Description

Wall connectors for plug-in low-carbon thermal insulation and energy-saving panels

technical field

The utility model belongs to building materials, in particular to a wall body connector of a plug-in low-carbon thermal insulation and energy-saving panel applied to the external eaves wall of a building.

Background technique

The installation of marble decorative surface or glass curtain wall on the outer eaves of the building is widely used in practice. The dry-hanging process of marble decorative surface is to use corrosion-resistant bolts and corrosion-resistant flexible connectors to dry-hang marble, granite and other decorative stones on the outer surface of the building structure, leaving a gap of 40-50mm between the stone and the structure. cavity. The veneer made by this process is allowed to produce an appropriate amount of displacement under the action of wind and earthquake forces to absorb part of the wind and earthquake forces without cracks and shedding. When the wind and earthquake force disappear, the stone will reset with the structure. Compared with the traditional wet work process, this process eliminates the grouting process, shortens the construction period, reduces the weight of the building, improves the seismic performance, and more importantly, effectively prevents the saline and alkali pigments in the grouting from penetrating the stone and improving Its decorative quality and perception effect. In addition, due to the expansion and contraction deformation of the exterior surface caused by seasonal outdoor temperature differences, the veneer may fall off. This process can effectively prevent the occurrence of accidents where the veneer falls off and hurts people. The glass curtain wall is the outer protective wall of the building and is not load-bearing. The composition of the glass curtain wall. It is composed of three parts: skeleton, glass and accessories. The skeleton is composed of longitudinal columns and crosspieces, which are used to support the glass, fix the glass, and connect with the wall structure through connectors. It transmits the self-weight of the glass, wind load and other loads to the main structure, so that the glass and the wall structure are integrated. The main accessories of the glass wall include expansion bolts, aluminum rivets, nails, sealing strip materials and connectors. The installation sequence of the frame is: install the vertical frame (column) first, and then install the horizontal frame (crosspiece). There are generally two ways to fix the vertical frame and the wall. One is to prepare the embedded parts when pouring the main structure, and then fix the frame after the connecting parts and the embedded parts are welded firmly. Another method is to drill holes in the main structure, use expansion bolts to fix the connectors to the wall, and then connect the skeleton to the connectors. The former is solidly reinforced, but the position of the embedded parts often differs from the installation. The latter is installed in an accurate position, but it takes a lot of work to drill holes, and its firmness is not as good as that of pre-embedded. The construction process of the above two kinds of dry-hanging external eaves and walls is complicated, and the connection between the connectors and the decorative materials requires relatively high technical conditions for the operators. Especially, it is time-consuming and expensive to drill dry-hanging holes on the side walls of marble. It will destroy its strength; the skeleton material of the curtain wall is wasted a lot, and the construction cost is very high.

Utility model content

The purpose of this utility model is to overcome the deficiencies of the above-mentioned technologies, and provide a wall connector of a plug-in low-carbon heat preservation and energy-saving board.
