This invention generally relates to a multi-story building floor support system. More specifically, the present invention relates to a multi-story building floor support system having a receptacle that is embedded into the building core and a chamber of the receptacle that is configured to receive a floor support structure.
Background Information
A conventional multi-story building can be constructed by building a building core as well as successive floor structural members at the ground level that are then lifted to the desired elevations of the building core. These floor structural members are supported at the various desired elevations adjacent the building core by support structures that are inserted into receptacles in the building core. Such receptacles may be constructed to include at least one chamber that receives the support structures therein. Recently, building core receptacles that support the floor structural members are constructed to be lightweight in order to decrease the cost of construction while maintaining durability against shear and strain forces caused by the external loads of the floor structural members.
Generally, the present disclosure is directed to various features of a multi-story building floor support system.
One aspect of the present invention is to provide a multi-story building floor support system having a receptacle and a first support member. The receptacle is configured to be embedded into a building core. The receptacle includes a first chamber, a first support plate and a second support plate. The first chamber has a first insertion opening. The first support plate protrudes from a top surface of the first chamber. The second support plate protrudes from a bottom surface of the first chamber. The first and second support plates are structured to retain the receptacle inside the building core. The first support member has a first end section and a second end section. The first end section is configured to be inserted into the first receiving opening of the first chamber such that the second end section projects outwardly from the first receiving opening of the first chamber.
A second aspect is to provide a multi-story building floor support system having a building core, a plurality of receptacles and a plurality of floor structural members. The building core is constructed from a slip-form process and has a plurality of corner areas at each elevation. Each of the receptacles is configured to be embedded into the building core. Each of the receptacles has a first chamber and a second chamber that are vertically aligned. The first chamber is configured to receive a first support member. The second chamber is configured to receive a second support member. Each of the floor structural members is supported at an elevation by the support members.

Selected embodiments will now be explained with reference to the drawings. It will be apparent to those skilled in the construction field from this disclosure that the following descriptions of the embodiments are provided for illustration only and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.
Referring initially to
Constructing the multi-story building 10 using a building core 22 (or a plurality of building cores) eliminates the use of columns and bracing elements. Preferably, the building core 22 is constructed from a slip-form process such as vertically slip forming a hardenable substance, such as concrete. Extendable elements, such as hydraulic jacks (not shown), may be used to push the slip form upward off the ground. Hydraulic jacks may also be used at various elevations of the building core 22 to push the slip form further upwards during building core 22 formation. Only one building core 22 is illustrated in this disclosure for the purposes of simplicity. However, it will be apparent to those skilled in the art from this disclosure that the building 10 may include a plurality of building cores formed by slip forming. These building cores can be coupled with one another so that the floor elevations of the building cores are aligned.

The building core 22 has a plurality of corner areas 32 at each elevation. Each receptacle 30 is embedded into a corner area 32 of the building core 22. Thus, in the illustrated embodiment, the multi-story building floor system 12 is designed such that each elevation of the building core 22 has four receptacles 30 embedded into the corner areas 32. The receptacles 30 are identical in size and structure so further description of the receptacles 30 will be in reference to a single receptacle 30.
In the current embodiment, the receptacle 30 is sized and dimensioned to be lightweight to reduce the cost of materials and construction. Specifically, in the illustrated embodiment, the receptacle 30 is designed to be 33 inches in height, 5 inches in width, and extends 12 inches into the building core 22. That is, when the receptacle 30 is embedded into the building core 22, it spans 33 inches long, 5 inches wide and extends 12 inches into the building core 22.

In the illustrated embodiment, the first and second horizontal plates 48 and 50 define the top and bottom outer surfaces of the first chamber 34, respectively. The first chamber 34 also has a first vertical plate 52 and a second vertical plate 54. In the illustrated embodiment, the first and second vertical plates 52 and 54 define the outer side surfaces of the first chamber 34. The first and second horizontal plates 48 and 50 are steel plates that are preferably 5 inches wide, ½ inch thick and extend 12 inches into the building core 2212 when the receptacle 30 is embedded. The first and second vertical plates 52 and 54 are steel plates that are preferably 4 inches long, ½ inch thick and extend 12 inches into the building core 22 when embedded. In this manner, the first chamber 34 spans 5 inches in the horizontal plane, 4 inches in the vertical plane and extends 12 inches into the building core 22. As previously stated, the first chamber 34 has the first receiving opening that is configured to receive the first support beam. Preferably, the inner walls of the first chamber 34 are lined with a lubricating member or substance (not shown) such as Teflon coating to facilitate insertion of the first support member 38 into the first chamber 34.
As previously stated, the receptacle 30 further includes the second chamber 36 with the second insertion opening 46 that is configured to receive and support the second support member 40 therein. The second chamber 36 is identical in size and structure to the first chamber 34. The second support plate 66 has first and second horizontal plates 48 and 50 as well as first and second vertical plates 52 and 54 in the same structure and configuration as the first chamber 34.
As previously stated, the receptacle 30 further includes the first, second and third support plates 64, 66 and 68. The first, second and third support plates 64, 66 and 68 serve to connect and retain the first and second chambers 34 and 36 inside the building core 22. In particular, the first, second, and third support plates 64, 66 and 68 are shop welded to portions of the first and second chambers 34 and 36 to form the receptacle 30. Preferably, in the illustrated embodiment, each of the first, second and third support plates 64, 66 and 68 are structured as ⅜ inch thick plates and are preferably sized so that they extend 12 inches into the building core 22 after embedding.
The first support plate 64 is a top plate that is shop welded to the first horizontal plate 48 (the top plate) of the first chamber 34. The first support plate 64 protrudes from the top outer surface of the first chamber 34. Thus, the first support plate 64 is a top plate of the receptacle 30 when the receptacle 30 is embedded into the building core 22. In the illustrated embodiment, the first support plate 64 measures preferably 6 inches in length when the receptacle 30 is embedded into the building core 22. As seen in
The first and second support plate 66s are connected by the second support plate 66, which is shop welded to the second horizontal plate 50 (the bottom plate) of the first chamber 34 and the first horizontal plate 48 (the top plate) of the second chamber 36. The second support plate 66 protrudes from the bottom outer surface of the first chamber 34 and the top outer surface of the second chamber 36. In this manner, a top surface of the second chamber 36 is connected to the second support plate 66 of the first chamber 34 so that the second chamber 36 is vertically aligned with the first chamber 34.
As previously mentioned, each of the first, second and third support plates 64, 66 and 68 includes at least one retaining member 70 protruding laterally therefrom. In the illustrated embodiment, each of the first, second and third support plates 64, 66 and 68 include 2 pairs of retaining members 70. Each one of the retaining member 70 of the pair of retaining members 70 protrudes in laterally opposite directions from its respective support plate. The retaining members 70 are identical in size and construction and thus further description of the retaining members 70 will be in reference to a single retaining member 70 of the first support plate 64. Preferably, the retaining member 70 is a Nelson stud. The retaining member 70 is secured to the first support plate 64 by stud welding in which the retaining member 70 is welded to the first support plate 64. The retaining member 70 is preferably ⅞ inches long. Thus, the retaining member 70 protrudes approximately ⅞ inches laterally from the first, second, or third support plate 68 when the receptacle 30 is embedded into the building core 22. The retaining member 70 is configured to fixedly contact a building structural member 72 of the building core 22 to secure the receptacle 30 into the building core 22. In the illustrated embodiment, the building structural remember 72 is a rebar and preferably a #5 rebar. As seen in
The first and second support members 38 and 40 will now be discussed in greater detail. As the first and second support members 38 and 40 are identical in size and construction. Thus, further description of the first and second support members 38 and 40 will be made in reference to the first support member 38 only. The first support member 38 is preferably a solid steel bracket that is approximately 10 inches long. The first support member 38 has a first end section 78 and a second end section 80. The first end section 78 is configured to be inserted into the first insertion opening 44 of the first chamber 34 such that the second end section 80 projects outwardly from the first insertion opening 44 of the first chamber 34. Preferably, the first support member 38 is inserted through the first through hole 77a of the first floor structural member 24 at the base 14 of the building 10. Thus, when the floor 20 is constructed on the coupled first and second floor structural members 24 and 26, the first support member 38 the first through hole 77a has the first support member 38 inserted therethough. The first support member 38 may be pushed into the first insertion opening 44 of the first chamber 34 by a hydraulic ram or a screw jack (not shown) that can be mounted on the second floor structural member 26. After insertion of the first support member 38 into the first chamber 34, the first chamber 34 can be filled with an epoxy or mortar to secure the first support member 38 therein. The coupled first and second floor structural members 24 and 26 are mounted on the first support member 38 such the second end section 80 of the first support member 38 will protrude from the first through hole 77a of the first structural member 24. Thus, the floor 20 is supported by the first support member 38 in the receptacle 30.
In the illustrated embodiment, the first support member 38 is configured to be inserted approximately 5 inches into the first insertion opening 44 of the first chamber 34 such that the first support member 38 protrudes 5 inches out of the first insertion opening 44. Optionally, stoppers 81 can be used to indicate the desired insertion amount of the first support member 38 into the first chamber 34.
As previously stated, the multi-story building support system 12 further comprises the second support member 40 that is configured to be inserted into the second insertion opening 46 of the second chamber 36 of the receptacle 30. In the same manner as the first support member 38, when the second support member 40 is supported in the second chamber 36, a first end section 82 of the second support member 40 is inserted into the second chamber 36 while a second end section 84 of the second support member 40 projects outwardly from the second insertion opening 46. The second end section 84 of the second support member 40 also extends through the second through hole 77b of the first floor structural member 24 that is coupled to the second floor structural member 26. In this manner, the floor 20 is supported by the first and second support members 38 and 40 within the receptacle 30. As each floor 20 of the building 10 is constructed at the base 14 and then lifted to its desired elevation 18, the first and second floor structural members 24 and 26 of each floor 20 are supported at its elevation 18 by the first and second support members 38 and 40.
