Description

Technical Field

[0001] The utility model relates to the technical field of connection between an ALC board and a floor slab or a beam, in particular to an auxiliary device for installing the ALC board. Background Art

[0002] ALC board is a new type of building material. It is a composite material board formed by cement, lime, mineral fiber and steam curing process with good thermal insulation, sound insulation and fire resistance. Its excellent properties such as light weight, thermal insulation and sound insulation make it one of the ideal choices for modern green energy-saving buildings. It is widely used in exterior walls and interior partitions of residential, office buildings, hotels and other buildings, as well as light roofs.

[0003] The difficulty in installing ALC panels lies in their connection with floor slabs or beams. Currently, there are usually the following ways to connect ALC panels with floor slabs or beams:

[0004] Fixed bolt connection: holes are reserved at the contact point between the ALC board and the floor or beam, and the two are fixed together by expansion bolts, chemical bolts, etc. This method has strong reliability and better stress transmission.

[0005] Mounting bracket connection: Pre-set metal brackets on the floor or beam, and then install the ALC board directly on the brackets. The brackets can be made of L-shaped steel, U-shaped steel, etc., welded or bolted. This makes it easy to install and remove the ALC board.

[0006] Embedded connection: A groove or flange is reserved on the edge of the floor or beam, and the edge of the ALC board is embedded in it and fixed with grouting. This connection method can improve the stability of the overall structure.

[0007] Adhesive connection: Apply high-strength structural adhesives such as epoxy resin and polyurethane on the contact surface between the ALC board and the floor or beam to achieve bonding connection between the two. This method can achieve smooth transition and reduce stress concentration.

[0008] Cast-in-place concrete connection: A layer of cast-in-place concrete is poured at the junction of the ALC board and the floor slab or beam to reliably combine the two. This connection method can give full play to the compressive properties of concrete.

[0009] In actual engineering applications, a combination of the above connection methods is usually used. For example, fixed bolts or embedded connections are used at the main load-bearing connections, and adhesives are used at non-load-bearing locations. However, the fixing effect of the above installation methods needs to be improved, and the impact resistance of ALC panels is poor. Utility Model Content

[0010] The technical problem to be solved by the utility model is to provide an auxiliary device for installing an ALC board which has the advantages of convenient operation, good fixing effect and strong impact resistance.

[0011] In order to achieve the above purpose, the utility model provides an auxiliary device for installing the ALC board, and the technical solution is as follows:

[0012] An auxiliary device for installing an ALC board is used to connect the ALC board on the bottom or top floor with a floor slab or a beam, and the auxiliary device includes: an L-shaped connector, a horizontal panel of the L-shaped connector is fastened to the floor slab or the beam, and a vertical panel of the L-shaped connector is adapted to the outer side of the ALC board; a hook head bolt, the hook head bolts are arranged at intervals along the length direction of the L-shaped connector; the hook portion of the hook head bolt is welded to the outer side of the vertical panel of the L-shaped connector, and the straight rod portion of the hook head bolt passes through the ALC board and is connected to a nut; an elastic pad, the elastic pad is arranged between the ALC board and the floor slab or the beam.

[0013] In the above-mentioned auxiliary device for installing the ALC board of the utility model, firstly, the ALC board is fixed at multiple points by arranging hook bolts welded and fixed to the L-shaped connector at intervals along the L-shaped connector, so that the connection is firm, and the stability and bearing capacity are strong. Secondly, by arranging elastic pads between the ALC board and the floor slab / beam, it can not only play a role in damping and shock absorption, alleviate local stress concentration, and improve the impact resistance of the overall connection, but also reduce the stress changes caused by temperature changes and improve the overall service life. It can be seen that the utility model adopts an auxiliary device composed of an L-shaped connector, a hook bolt and an elastic pad, which can effectively and reliably connect the ALC board to the floor slab or beam, and ensure the bearing capacity, seismic resistance and impact resistance of the connection part.

[0014] As a further improvement of the auxiliary device for installing the ALC board, the horizontal panel of the L-shaped connector is fixed to the floor or beam by metal expansion bolts, and the arrangement spacing of the metal expansion bolts is 50 to 70 cm. Therefore, the metal expansion bolts with the above arrangement spacing can ensure a sufficient number of fixing points without being too dense, which is convenient for construction operations. The mechanical fixing method of the metal expansion bolts, coupled with a reasonable arrangement spacing, can enhance the reliable connection between the L-shaped connector and the floor / beam, which can not only bear the dead weight of the ALC board, but also resist external forces and improve the stability of the overall structure.

[0015] As a further improvement of the auxiliary device for installing the ALC board, the L-shaped connector is formed by welding at least two angle steels at the first ends. Thus, the cross-sectional performance of the angle steel can be fully utilized, the overall bending and shearing resistance can be improved, and a larger external load can be borne, providing reliable support for the ALC board; welding at least two angle steels at the first ends together to form an L-shaped integral component can ensure the overall continuity of the component, avoid local stress concentration, and improve the overall rigidity and stability.

[0016] As a further improvement of the auxiliary device for installing the ALC board, the arrangement spacing of the hook bolts is 10 to 30 cm. As a result, the force on the ALC board is more evenly distributed, and the stress borne by a single hook bolt is relatively reduced, thereby improving the total bearing capacity of the entire connection system; improving the connection reliability between the ALC board and the L-shaped connector, improving the seismic performance, reducing the risk of local stress concentration, better controlling the deformation of the ALC board, and ensuring the stability of the connection part.

[0017] As a further improvement of the auxiliary device for installing the ALC board, a first strip groove matching the total thickness of the vertical panel and the hook is provided on the outer side of the ALC board. A second strip groove matching the thickness of the nut is provided on the inner side of the ALC board. Thus, the provision of the strip groove can not only improve the overall integration of the connection part and reduce stress concentration, but also avoid the connection component being directly exposed on the surface of the ALC board, which is convenient for the subsequent construction of the surface layer and the decorative layer.

[0018] As a further improvement of the auxiliary device for installing the ALC board, the matching length between the hook and the vertical panel is 1 to 3 cm, thereby improving the connection reliability between the hook and the vertical panel.

[0019] As a further improvement of the auxiliary device for installing the ALC board, the bottom of the ALC board is provided with a groove, and the top is provided with a protrusion, and the upper and lower ALC boards are connected by inserting the protrusion and the groove. Thus, the contact area is increased, and the stability of the connection and the construction efficiency are improved.

[0020] As a further improvement of the auxiliary device for installing the ALC board, the elastic pad includes a first pad and a second pad of different thicknesses. Thus, the pad thickness can be reasonably matched according to the gap width of different parts, thereby enhancing the integration of the ALC board with the floor or beam, and improving the stability and seismic performance of the overall structure.
