Description
FIELD OF THE INVENTION

The present invention relates generally to a collapsible building frame structure, and more particularly, the present invention effectively improves the traditional building process by optimizing the construction process by providing a collapsible building frame to shorten the building time. The present invention further comprises two different structural designs that can make the user possible to choose different designs of collapsible frames according to the needs at the time of use.


BACKGROUND OF THE INVENTION

The following background information may present examples of specific aspects of the prior art (e.g., without limitation, approaches, facts, or common wisdom) that, while expected to be helpful to further educate the reader as to additional aspects of the prior art, is not to be construed as limiting the present invention, or any embodiments thereof, to anything stated or implied therein or inferred thereupon.


Today the demand in the housing market is increasing due to the continuous increase in the world population. Traditional methods of building houses use load-bearing structures, which consume a lot of labor and materials, have a large amount of building materials to transport, take a long time to build, and often generate a lot of construction waste at the construction site due to the construction method, resulting in a poor construction environment.


The common building structures consist of reinforced concrete structure, steel beam structure, wood structure, and light steel structure. Traditional reinforced concrete structure takes a long time to build and have a poor building environment, while wood frame structures are less costly but can carry lower loads. Light steel structures have a more complex structure than other methods. Steel-beam framed structures show clear advantages in these building structures.


Traditional steel beam structures require the assistance of mechanical tools such as cranes to complete the movement and installation because of the high density of steel materials. Machinery that can move steel beams is generally large in size, takes a long time to transport or move, and is costly. When installing the frame, it takes time to position the steel because it does not have pre-set connections.


Many prefabricated structures of construction can be manufactured in factories and transported to the construction site for direct installation, which is convenient and fast. However, current prefabricated structures are mostly prefabricated concrete slabs and prefabricated walls, which take longer to transport than traditional reinforced concrete structures, and save less time when constructed at the construction site. Also, prefabricated structures are too simple, resulting in no great improvement in prefabricated methods of construction compared to traditional construction.


Thus, there is still a need for a new construction model or house construction method. The new construction method will change the existing construction mode if it can: use steel structure for the main body, simplify the frame installation process, avoid, or minimize the use of large machinery, increase the interaction between structures, and transport easily. The present invention is dedicated to meet the above needs by inventing a new steel frame to realize this future concept of construction method.

Specific dimensions and other physical characteristics relating to the embodiments disclosed herein are therefore not to be considered as limiting, unless the claims expressly state otherwise.


Please refer to FIGS. 1-3, they illustrate the schematic views of collapsible building frame structure in the expended & contracted status and the detailed components that is needed to build the present invention. In the present invention, a collapsible building frame structure 1, which is a cuboid or a cube, has 8 corner units 11 and a plurality of horizontal sleeve rods 12. Each corner unit 11 has two horizontal rods 111 and a vertical rod 112, the horizontal rods 111 and the vertical rod 112 are perpendicular to each other, and the vertical rods 112 of every two vertically adjacent corner units 11 are connected and fixed to each other. The horizontal sleeve rods 12 are hollow rod bodies, and the horizontal sleeve rods 12 are arranged between any two horizontally adjacent corner units 11, and two ends of the horizontal sleeve rods 12 are respectively for the horizontal rods 111 of the two horizontally adjacent corner units 11 to be inserted, and move within the horizontal sleeve rods 12 to adjust the size of the collapsible building frame structure 1. Through the above structure, the collapsible building frame structure 1 can freely switch between the expanded status and the contracted status. In the contracted status, it can make it easier for workers to transport, and at the construction site, the workers only need to convert it from the contracted status to the expanded status to quickly build the framework of the building, which greatly reduces the time required for construction.


In this embodiment, one end of each horizontal rod 111 is provided with a fixing member 113, and the fixing members 113 are provided with a plurality of protruding structures 1131, and surfaces adjacent to two ends of each horizontal sleeve rod 12 are respectively provided with a plurality of holes 121 correspondingly for the protruding structures 1131 to be inserted into the holes 121 to detachably attach the horizontal rod 111 in the horizontal sleeve rod 12, like shown in FIG. 9, the pulleys 114 are rolling smoothly in the chutes 122. Such a structure allows the collapsible building frame structure 1 to expand and contract more efficiently, and there is no need to worry about the stability of the structure when it is in expanded status. In addition, a plurality of springs 1132 is arranged in the fixing member 113, which is connected with the protruding structures 1131, so that the protruding structures 1131 can expand and contract through elastic force. With the assistance of the elastic force, the structural rigidity of the collapsible building frame structure 1 will be stronger when it is in the expanded status, and the time for workers to switch between the expanded status and the contracted status can be reduced due to the setting of the springs 1132.


Furthermore, the present invention also provides a plurality of chutes 122 in each of the horizontal sleeve rods 12, and a plurality of pulleys 114 are provided on surface of each of the horizontal rods 111 adjacent to the fixing member 113 for the horizontal rod 111 to slide within the horizontal sleeve rod 12, like shown in FIGS. 10A & 10B. Such a chute 122 and pulley 114 structure make the collapsible building frame structure 1 smoother when contracting or extending, and less prone to failure and derailment. That is, the pulleys 114 roll in the chutes 122 during the unfolding of the frame 1 to help the parts of the frame 1 move against each other. When the frame 1 is fully expanded, a self-locking mechanism (the fixing member 113) on the hollow steel structure locks the steel beams in place, and the frame 1 is subsequently further strengthened by adding bolts 13, like shown in FIG. 8, to ensure the frame 1 cannot be expanded or loose while transporting. The bolts 13 can lock the horizontal rod 111 and horizontal sleeve rod 12 (which has holes 14 corresponding to the bolts) to ensure that the frame 1 is stable in both contracted status and expanded status.


Please refer to FIGS. 4-8, they illustrate the schematic views of collapsible building frame structure in the expended & contracted status and the detailed components that is needed to build the present invention. In this embodiment, the present invention provides another collapsible building frame structure 2 which is a cuboid or a cube with a plurality of first sides 201 and a plurality of second sides 202, any two of the first sides 201 are parallel to each other, and any two of the second sides 202 are parallel to each other, and the first sides 201 and the second sides 202 are perpendicular to each other. The collapsible building frame structure 1 has 8 corner units 21, a plurality of multi-connecting units 22, and a plurality of T-shape units 23. Each corner unit 21 has two corner horizontal rods 211 and a corner vertical sleeve rod 212, the corner horizontal rods 211 and the corner vertical sleeve rod 212 are perpendicular to each other, and the corner vertical sleeve rods 212 of every two vertically adjacent corner units 21 are connected through a vertical connecting rod 24. The multi-connecting units 22 are located on the first sides 201, each of the multi-connecting units 22 has two horizontal sleeve rods 221, a horizontal rod 222 and a vertical sleeve rod 223, the horizontal sleeve rods 221 are located on a same straight line, and the horizontal sleeve rods 221, the horizontal rod 222, and the vertical sleeve rod 223 are perpendicular to each other, and the vertical sleeve rods 223 of every two vertically adjacent multi-connection units 22 are also connected through the vertical connecting rod 24, and the horizontal sleeve rods 221 are each connected to the adjacent corner horizontal rods 211 through a horizontal connector 25, and the horizontal connectors 25 are open at one end for the insertion of the corner horizontal rods 211, and the other end is a closed surface for insertion into the horizontal sleeve rods 221. The T-shape units 23 are located on the second sides 202 and connecting lines between the horizontal rods 222 of the multi-connecting units 22, each of the T-shape units 23 having two auxiliary horizontal sleeve rods 231 and an auxiliary vertical sleeve rod 232, and the auxiliary vertical sleeve rods 232 of every two vertically adjacent T-shape units 23 are also connected through the vertical connecting rod 24, and the auxiliary horizontal sleeve rods 231 are also each connected to the adjacent horizontal rods 222 or the corner horizontal rods 211 through the horizontal connectors 25.


In this embodiment, the collapsible building frame structure 1 utilizes the following ways to adjust its expanded status and contracted status:

    • The corner vertical sleeve rods 212, the vertical sleeve rods 223 and the auxiliary vertical sleeve rods 232 are respectively moved on the vertical connecting rods 24 to adjust the height of the collapsible building frame structure 1.
    • Linkages of the horizontal sleeve rods 221, the horizontal connectors 25 and the corner horizontal rods 211 can adjust the length of the collapsible building frame structure 1 on the first sides.
    • Linkages of the auxiliary horizontal sleeve rods 231, the horizontal connectors 25, and the horizontal rods 222 and linkages of the auxiliary horizontal sleeve rods 231, the horizontal connectors 25 and the corner horizontal rods 211 are used to adjust the length of the collapsible building frame structure 1 on the second sides.


In addition, like shown in FIGS. 4-6, one end of the corner horizontal rods 211, one end of the horizontal rods 222, both ends of the vertical connecting rods 24 and closed ends of the horizontal connectors 25 are each provided with a fixing member 26, and the fixing members 26 are provided with a plurality of protruding structures 261, and adjacent to one end surface of the horizontal sleeve rods 221, one end surface of the vertical sleeve rods 223, one end surface of the auxiliary vertical sleeve rods 232, one end surface of the corner vertical sleeve rods 212, and one end surface of the auxiliary horizontal sleeve rods 231 are respectively provided with a plurality of holes 27 correspondingly for the protruding structures 261 to be inserted into the holes 27. Since the expansion and contraction in the horizontal direction are carried out in the same way, and the expansion and contraction in the vertical direction are also carried out in the same way, the present invention only shows part of the structure in the horizontal direction and part of the structure in the vertical direction, so that all the expansion and contraction modes of the present invention can be clearly represented.


In addition, such a structure can make the expansion and contraction of the collapsible building frame structure 2 more efficient, and it is not necessary to worry about the stability of the structure 2 when it is in the expanded status. And see also FIGS. 10A & 10B, a plurality of springs 262 is arranged in the fixing member 26, which is connected with the protruding structures 261, so that the protruding structures 261 can expand and contract through elastic force. With the assistance of the elastic force, the structural rigidity of the collapsible building frame structure 2 will be stronger when it is in the expanded status, and the time for workers to switch between the expanded status and the contracted status can be reduced due to the setting of the springs 262.


Furthermore, like shown in FIG. 9, in this embodiment, the horizontal sleeve rods 221, the vertical sleeve rods 223, the auxiliary vertical sleeve rods 232, the corner vertical sleeve rods 212, and the auxiliary horizontal sleeve rods 231 are provided with a plurality of chutes 28, and the corner horizontal rods 211, the horizontal rods 222, the vertical connecting rod 24, and the horizontal connectors 25 are respectively provided with a plurality of pulleys 29 on surface adjacent to the fixing member 26 for the pulleys 29 to slide on the chutes 28. Such a chute 28 and pulley 29 structure makes the collapsible building frame structure 1 smoother when contracting or extending, and less prone to failure and derailment.


In other words, the collapsible frame structure 1 has five sets of collapsible beams on upper portion, five sets of collapsible beams on lower portion, and nine sets of collapsible columns. One set of collapsible beams includes three multi-axial chute steel connectors connected by two sections of hollow steel structures with built-in chute 28 and pulleys 29. One set of collapsible columns consists of two multi-axial chute steel connectors connected by a section of hollow steel structure with built-in chute 28 and pulleys 29. The pulleys 29 roll in the chutes 28 during the unfolding of the frame 2 to help the parts of the frame 2 move against each other. When the frame 2 is fully expanded, a self-locking mechanism (the fixing member 26) on the hollow steel structure locks the steel beams and columns in place, and the frame 2 is subsequently further strengthened by adding bolts 203, like shown in FIG. 2, to ensure the frame 2 cannot be expanded or loose while transporting. When the frame 2 is in the expanded status, the bolts 203 can also be used to further strengthen the structural rigidity of the frame 2. That is, the bolts 203 can lock the all the rods and all the sleeve rods (which have holes 204 corresponding to the bolts 203) to ensure that the frame 2 is stable in both contracted status and expanded status. Furthermore, the frame 2 can be used alone or together with several frames 2 to expand the floor area, like shown in FIG. 11.


These and other advantages of the invention will be further understood and appreciated by those skilled in the art by reference to the following written specification, claims and appended drawings.


Because many modifications, variations, and changes in detail can be made to the described preferred embodiments of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be determined by the appended claims and their legal equivalence.
