Description

Technical Field

[0001] The utility model belongs to the technical field of prefabricated buildings, and particularly relates to a slidable dry connection node between a precast concrete external wall panel and a precast concrete beam. Background Art

[0002] In recent years, with the development and in-depth popularization of prefabricated buildings, precast concrete external wall panels have been widely used in prefabricated buildings due to their good seismic resistance, wind resistance, impact resistance and other properties. At present, the connection nodes between precast concrete exterior walls and the main structure often adopt a wet connection method in which anchor bars are embedded in the exterior wall panels and cast together with cast-in-place concrete beams. This connection node has poor deformation capacity and is prone to cracking when the exterior wall panels are subjected to earthquake action, wind load, or under long-term vertical load.

[0003] Therefore, it is necessary to provide a slidable dry connection node between a precast concrete external wall panel and a precast concrete beam for use. Summary of the Utility Model

[0004] The embodiment of the utility model provides a slidable dry connection node between a precast concrete external wall panel and a precast concrete beam to solve the problems in the prior art.

[0005] The embodiment of the utility model adopts the following technical scheme: A slidable dry connection node between a precast concrete external wall panel and a precast concrete beam includes a precast concrete external wall panel, a precast concrete beam, a beam top adjusting support and a beam bottom limiting support. Wall top embedded parts and wall bottom embedded parts are respectively arranged on the precast concrete external wall panel;

[0006] The precast concrete external wall panel is connected through the beam top adjusting support, the beam bottom limiting support and the wall top embedded part and the wall bottom embedded part;

[0007] The precast concrete external wall panel is connected to the precast concrete beam and the beam top adjusting support.

[0008] The utility model solves the problems of obvious in-plane and out-of-plane deformation of the precast concrete external wall panel under long-term load, cracking of the wall panel, damage of the wall panel, etc., and further ensures the waterproof and heat insulation performance of the wall panel.

[0009] Further, the beam top adjusting support includes a beam top embedded part, a channel steel bracket, a height adjusting screw rod, a bolt and an adjusting base. The channel steel bracket is connected to the beam top embedded part. The bolt is located on the channel steel bracket. The height adjusting screw rod is threadedly connected to the bolt. The adjusting base is located on the height adjusting screw rod. The channel steel bracket is connected to the wall top embedded part and is tightened through the height adjusting screw rod.

[0010] Furthermore, the beam bottom limit support includes a beam bottom embedded part, a beam bottom angle steel bracket, a connecting angle steel and a connecting bolt. The beam bottom angle steel bracket is provided with an oblong hole. The beam bottom angle steel bracket is connected to one side of the beam bottom embedded part. The connecting angle steel is connected to the beam bottom angle steel bracket through the connecting bolt passing through the oblong hole. The connecting angle steel is connected to the wall bottom embedded part through a bolt.

[0011] The above at least one technical solution adopted in the embodiment of the present utility model can achieve the following beneficial effects:

[0012] First, the dry connection between the precast concrete exterior wall panel and the main structure can be realized through bolts for this connection node. This connection node has the advantages of clear force transmission path, convenient installation, environmental protection, etc. The beam upper end adjustment support bears the vertical load of the precast concrete exterior wall panel, and the support height can be adjusted to reduce the installation error. The oblong hole is opened in the angle steel bracket of the beam bottom limit support in the direction outside the wall plane. During installation, the installation error outside the wall plane of the wall panel can be adjusted through the oblong hole. This node solves the problems such as obvious in-plane and out-of-plane deformation of the precast concrete exterior wall panel under long-term load, cracks and damage of the wall panel, and further ensures the waterproof and heat preservation performance of the wall panel.

[0013] Second, in the prior art, the precast concrete exterior wall panel often adopts wet connection, and the wall panel and the main structure are fixedly connected. The wall panel cannot deform in coordination with the main structure under long-term load, and cracks and even damage are likely to occur in the precast concrete exterior wall panel, and the waterproof performance of the exterior wall cannot be guaranteed. This patent adopts an adjustable dry connection node, enabling the precast concrete exterior wall panel to deform in coordination with the main structure, greatly reducing the generation of cracks and ensuring the waterproof effect of the exterior wall. The dry connection node has high construction efficiency, and only bolts are needed to complete the installation after the wall panel is in place. BRIEF DESCRIPTION OF THE DRAWINGS
