Description

Back-hung anchor-bolt stone curtain wall structure with waterproof layer

technical field

The utility model relates to a curtain wall structure of a building, in particular to a back-hanging anchor bolt type stone curtain wall structure with a waterproof layer.

Background technique

There are three main dry-hanging techniques for building exterior stone materials: steel pin type, short groove type and back bolt type. Among them, the steel pin type has defects such as ① punching holes are easy to cause damage; ② point force, poor safety; ③ points can only be placed on the edge of the board, which cannot meet the needs of large-sized boards on the wall, and has been eliminated. The disadvantages of the short groove type are: ①The hardness of the stone is high, and it is easy to cause damage when slotting; ②The point can only be arranged on the edge of the board, and the way of force is unreasonable, and when the stone size is large and the height of use is high There are defects that cannot be effectively arranged; ③ cannot be replaced individually, and cannot meet the needs of the curtain wall; the back-bolt type (back-hung anchor type) has the characteristics of reliable and stable dry hanging and individual replacement, and can be used for larger stones or is safe for stones. Occasions with high performance requirements.

The technological principle of the back-bolt stone curtain wall is: the column and the main structure are connected by embedded parts and bolts, and then the transverse keel is welded to the main keel, and the stone and the transverse keel are connected together by the back bolt and the connector, and the main keel is not Instead of direct force, the self-weight of the stone and the external load are transmitted to the main keel through the horizontal keel, and then to the main structure. Among them, the connector can be a three-dimensionally adjustable connection structure, such as the three-dimensionally adjustable stone curtain wall connection structure (CN2679267) disclosed in the Chinese utility model patent, through the adjustment of the relative position between the pendants, it is fixed with bolts, so as to facilitate the stone installation process It can be adjusted in all directions in order to meet the process requirements such as flatness and straightness; at the same time, it is beneficial to the replacement of a single stone.

Because the stone slabs in the prior art are directly connected to the main structure (wall) through the connectors, the main keel and the transverse keel, in order to prevent rainwater from flowing into the interlayer of the two through the joint between the stone slabs and the stone slabs, causing the wall to collapse. Water seepage is generally filled with sealant, which is likely to cause secondary pollution to the surface of the slate and needs to be cleaned in time. At the same time, the overall feeling of the wall is also affected, and the aesthetics are poor.

Contents of the invention

The purpose of the utility model is to provide a back-hanging anchor bolt-type stone curtain wall structure with a waterproof layer. The curtain wall of this structure can avoid the use of sealant, avoid secondary pollution, and improve the overall aesthetics of the wall surface.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a back-hanging anchor bolt type stone curtain wall structure with a waterproof layer, including a plurality of stone slabs, a plurality of main keels, connecting components and a plurality of horizontal keels, the stone slabs The connecting component is connected with the transverse keel, the transverse keel is welded and fixed to the main keel, the main keel is welded and fixed with the embedded parts in the main structure through the connecting piece, and the connecting component is connected through connecting bolts, transfer Corner brackets and bolts are connected to the horizontal keel, a waterproof layer is provided between the stone slab and the main structure, and a through hole is opened on the waterproof layer corresponding to the connection between the connecting component and the transfer corner bracket, The waterproof layer is fixed between the connection assembly and the transfer corner code through the connection bolts passing through the through hole.

In the above technical solution, the connection assembly includes a back bolt on the back side of the stone slab, an adjustment mechanism connected to the back bolt, and a second transfer corner code connected to the transfer corner code installed on the transverse keel, and the waterproof layer It is sandwiched between the transfer corner code and the second transfer corner code, that is, between the connecting component and the horizontal keel, and passes through the transfer corner code (installed on the horizontal keel), the waterproof layer, the second rotating frame through the connecting bolt. After connecting the corner code (in the connection component), it is fixed by nuts. Since the waterproof layer is set between the stone slab and the main structure, it provides a waterproof barrier for the main structure. Therefore, there is no need to fill the sealant between the stone slabs outside the waterproof layer. Or other sealing structures to avoid secondary pollution of the sealant and improve the overall aesthetics of the slate wall.

In the above technical solution, the waterproof layer is formed by splicing a plurality of waterproof boards, two overlapping layers with an overlapping length of not less than 50 mm are provided at adjacent boards, and the upper waterproof board is stacked on the outside of the lower waterproof board, and the upper waterproof board A sealant layer is arranged between the end of the waterproof board and the lower waterproof board. During construction, it is laid sequentially from bottom to top. The upper waterproof board is located on the outer side of the lower waterproof board, that is, near the side of the stone slab, and the waterproof sealant is applied to the lap between the upper waterproof board and the lower waterproof board on the outer side. , to prevent water leakage.

In the above technical solution, a sealing ring is provided at the joint of the waterproof layer, and the sealing ring is sheathed on the connecting bolt at the joint.

A further technical solution is that the waterproof layer is a galvanized iron sheet layer, and its surface is coated with an anti-corrosion paint layer.

In the above technical solution, the outer side of the main structure is provided with an insulating layer, and the connecting piece for installing the main keel penetrates through the insulating layer and is welded and fixed to the embedded parts in the main structure. The insulation layer can adopt insulation material (such as polystyrene insulation board) with a thickness of about 40mm. When laying on the main structure, it is fixed by insulation nails to provide insulation effect for the curtain wall.

Due to the use of the above technical solutions, the utility model has the following advantages compared with the prior art:

1. Since the utility model is provided with a waterproof layer between the stone slab and the main structure, the connecting bolts of the fixed connection assembly and the transfer angle code (installed on the horizontal keel) penetrate through the through hole on the waterproof layer, and the waterproof layer is clamped It is held and fixed between the connection component and the adapter corner, providing a waterproof barrier for the main structure on the inside, so that the gap between the stone slabs on the outside does not need to be filled with sealant, avoiding the secondary pollution of the glue, and improving the integrity of the wall. aesthetics;

2. The insulation layer is laid on the main structure to provide insulation effect for the stone curtain wall.
