The disclosure relates to the technical field of building construction, and more particularly, to a connecting member, an ALC (Autoclaced Lightweight Concrete) batten mounting node structure, and a prefabricated mounting method.
At present, prefabricated steel structure buildings are developing vigorously in China. With a large market demand, the prefabricated buildings are still the development trend of future buildings. The fabricated steel structure buildings have a very mature structure system currently, and structure safety can be fully guaranteed. The difficulties lie in the selection of three-plate parts and the connection between the three-plate parts and a main structure. A production method for a mounting detail node of an ALC batten of a wall which is one of the three-plate parts is one of the key points that directly affect a quality and a sensory feeling of a whole residential wall. The ALC batten, also known as an autoclaved aerated concrete plate, is a porous silicate product formed, by using silica sand, cement, quicklime and gypsum as raw materials, and aluminum powder as a foaming agent, through a series of technological processes (batching, reinforcement, foaming, and cutting), and finally through high temperature and high pressure steam curing, with a series of advantages including a light weight and a high strength. However, in an actual construction process, when the ALC batten is spliced and mounted, it is prone to deviation during mounting and positioning, and movement under an action of an external force, so that it is very inconvenient and inefficient to mount an ALC batten mounting node.

In implementation, the first pipe clamp 31 and the second pipe clamp 32 may be positioned to be staggered with each other to disperse stress. For example, in the embodiment shown in
The second connecting segment 34 is bent towards one side of the first connecting segment 33, which is convenient to be fixedly connected with an upper mounting structure of the ALC batten, so that the ALC batten can be fixedly connected at a required position. According to a connection requirement, an included angle between the second connecting segment 34 and the first connecting segment 33 is set as required, in the embodiment, the included angle between the second connecting segment 34 and the first connecting segment 33 is a right angle, and the second connecting segment and the first connecting segment can be connected onto a steel beam above the ALC batten, thus being suitable for an internal or external partition wall below the steel beam, and convenient and firm in connection.
Specifically, the connecting part may be of a plate-like structure, which is beneficial for reducing a width of a seam between the adjacent ALC battens, and enables a seaming position to be more flat. The first pipe clamp 31 and the second pipe clamp 32 are respectively connected onto plate surfaces on two sides of the first connecting segment 33, and the first connecting segment 33 and the second connecting segment 34 may be formed by bending a same plate member, or splicing and connecting two plate members.
A flexible material 4, such as a foaming adhesion agent, is filled between tops of the first ALC batten 21 and the second ALC batten 22, and the steel beam 1, thus forming flexible connection. A seam is arranged between the first ALC batten 21 and the second ALC batten 11, and bonding mortar 5 is filled in the seam. In specific implementation, a certain distance is kept when the first pipe clamp 31 and the second pipe clamp 32 are inserted into the first ALC batten 21 and the second ALC batten 22, so that a gap 6 is provided between the first connecting segment 33, and the first ALC batten 21 and the second ALC batten 22. When the bonding mortar 5 is filled in the seam, the bonding mortar 5 is also filled in the gap 6.
In the embodiment, the first ALC batten 21 is provided with a concave structure 211 at a position corresponding to the connecting member 3, and the second ALC batten 22 is provided with a convex structure 221 matched with the concave structure 211 at a position corresponding to the connecting member 3, so that a seam 7 with an irregular cross section is formed at a seaming position of the adjacent ALC battens, which is beneficial for increasing a connecting area of the adjacent ALC battens, and improving a stability at a connecting position of the seam.
The patent NON-WELDING FLEXIBLE STEEL BEAM CLAMPING MEMBER FOR ALC BATTEN INTERIOR WALL AND U-SHAPED CLAMP NODE STRUCTURE with publication No. CN206941882U provides a non-welding flexible steel beam clamping member for an ALC batten interior wall and a U-shaped clamp node structure in a prefabricated steel structure building. The steel beam clamping member is formed by bending a steel plate, and a clamping groove matched with the steel beam is arranged on the steel beam clamping member. Inner sides of bent parts on two sides of the clamping groove are both provided with a clamping limiting protrusion, and an outer bottom surface of a middle part of the steel beam clamping member is a welding connection surface of the U-shaped clamping member.
The technical solutions provided by the patent application have the following disadvantages.
1. The patent only puts forward details of a node of a U-shaped clamp, without describing an application scope in detail. If a width of an ALC wall is less than a width of a beam flange plate, a width of the U-shaped clamp is reduced correspondingly, and then whether the clamping limiting protrusion may still be applied is uncertain.
2. A whole U-shaped clamp device is connected with the flange plate by the clamping limiting protrusion, and a connection strength is not guaranteed.
According to the ALC batten mounting node structure and the connecting member 3 provided by the embodiment of the disclosure, the connecting member 3 with double-sided pipe clamps is mounted in a vertical seam between two ALC battens 2, and the pipe clamps on two sides of a connecting plate directly extend into mounting holes in side surfaces of the prefabricated ALC battens 2, so that the pipe clamps at one node position fix the two adjacent ALC battens 2 at the same time. The second connecting segment 34 of the connecting member 3 is bent at the top of the ALC batten and welded on the lower flange plate of the steel beam 1, and is hidden in the top surface of the ALC batten, so that a finished surface of the wall is more beautiful and integrated, thus being suitable for mounting ALC battens of all thicknesses, being capable of optimizing construction sequence and method of the ALC battens, and improving a mounting accuracy of the battens.
According to an embodiment of the disclosure, there is further provided a prefabricated mounting method based on the above ALC batten mounting node structure.
The first ALC batten is arranged below the steel beam.
The connecting member is arranged on one side of the first ALC batten, the first pipe clamp is embedded in the first ALC batten, and the second connecting segment of the connecting member is fixedly connected with the steel beam.
The second ALC batten is mounted on one side of the first ALC batten, so that the second pipe clamp is embedded in the second ALC batten. Mounting holes may be arranged in the ALC battens at corresponding positions in advance to facilitate insertion and mounting of the first pipe clamp or the second pipe clamp during mounting.
According to the above mounting method, the ALC battens at the ALC batten mounting node are mounted in sequence, one of the ALC battens may be measured and positioned first, then the connecting member is mounted and fixed, and then the other ALC batten is mounted on the other side of the connecting member, thus effectively preventing deviation or displacement of the ALC battens during mounting, improving a mounting accuracy, ensuring a flush mounting surface, and having strong operation and implementation.
A flexible material, such as a foaming adhesion agent, is filled between tops of the first ALC batten and the second ALC batten, and the steel beam, thus forming flexible connection. The bonding mortar is filled in the seam between the first ALC batten and the second ALC batten. When a connecting plate is mounted, a certain distance is kept when the first pipe clamp and the second pipe clamp are inserted into the first ALC batten and the second ALC batten, so that a gap is provided between the first connecting segment, and the first ALC batten and the second ALC batten respectively, so that the bonding mortar is capable of being filled in the gap, which is beneficial for improving a stability at the connecting position.
Positioning method of the first ALC batten may use a conventional way of plumb bob paying-off. A required positioning line is arranged according to a designed position on the ground and wall and top surfaces, and the first ALC batten is positioned and arranged according to the positioning line.
The patent application CONSTRUCTION METHOD FOR PREFABRICATED PARTITION WALL BASED ON ALC BATTEN with publication No. CN106499091A provides a construction method for a prefabricated partition wall based on an ALC batten. The batten is mounted by manual transverse and longitudinal compaction, which is beneficial for combining an adhesion agent with a plate and a concrete surface, and ensures that there is no large stress on a wall and a seaming position after curing and shrinkage of the adhesion agent, so that a possibility of cracks on the wall and the seaming position is greatly reduced. During construction, mounting of the ALC batten is further adjusted and calibrated, thus improving a forming quality of the wall.
The technical solutions provided by the patent application have the following disadvantages.
1. The mounting method using manual transverse and longitudinal compaction for combining the adhesion agent with the plate and the concrete surface is inefficient, and the manual compaction cannot guarantee uniform adhesive force and gap between bonding surfaces, thus being poor in forming.
2. There is no fastener for fixing the ALC batten in the construction method, which is prone to deviation during mounting and positioning, especially prone to movement under an action of an external force of the manual compaction.
In some of other conventional structures and solutions, a U-shaped clamp is used to fix a top end of the batten. The U-shaped clamp is fixed on structural beam and plate in the seam between the top ends of two battens through a nail gun.
According to the ALC batten mounting node structure and the prefabricated mounting method based on the ALC batten mounting node structure provided by the embodiments of the disclosure, sequential mounting can be implemented. An ALC batten on an edge of an end part is positioned below the steel beam first, then the connecting member is mounted, and then the next ALC batten is mounted. The connecting member is provided with double-sided pipe clamps, an adjacent ALC batten may be directly inserted into the pipe clamp on an opposite side according to the position of the pipe clamp, and the sequential mounting is implemented in a sequence of “ALC batten—connecting member—ALC batten”, so that the mounting method is simple and easy to operate, improving mounting efficiency and guaranteeing the flatness of a wall appearance. Moreover, the fixation is firm by the fixing method, and one connecting member may fix two ALC battens at the same time, which enables the fixation of the battens to be more stable and improves a stability of the structure, thus being suitable for all prefabricated buildings with a steel structure as a main body and the ALC batten as the partition wall. For example, buildings with a steel structure as a main frame and an I-shaped structural steel beam, such as a residential building and a commercial building, are widely popularized.
The above is only some embodiments of the disclosure, but the disclosure is not limited to the above embodiments. A person of ordinary skill in the art may further make multiple equivalent modifications or substitutions without violating the gist of the disclosure, and these equivalent modifications or substitutions are all included in the scope defined by the claims of the present application.
