Zipper-type wall part and zipper key for producing the same

Abstract

The invention relates to a zipper-type wall part, also relates to a zipper key for the production of the zipper-type wall part. A zipper-type wall part is provided with a wedge groove in at least one corner of the part, and optionally the wedge groove edge is provided with a notch. The zipper-type wall part is characterized in that at least one side of the wedge groove is provided with one or more, preferably two or more than two grooves or protrusions. The invention can achieve the beneficial effects of: a pouring material in the zipper groove can be dispersed by gravity to each groove or protrusion, so as to avoid the uneven density in pouring; and stress between each layer of grooves or protrusions can be dispersed into the respective sides of the zipper groove, so as to avoid stress and rupture due to excessive local stress concentration and improve the overall quality of wall construction.

Description

technical field [0001] The present invention relates to a zippered wall component (eg, including building wall panels), and the invention relates to a zipper key for use in making the component. Background technique [0002] With the extensive implementation of "green building" and "energy-saving building", wall parts such as lightweight building wall panels made of renewable resources will gradually become important components of the wall. Due to the late design of light-weight building wall panels in China, many key technologies have not been well resolved so far. Such as: the connection between board and board Most producers and users make the board into convex and concave grooves, and then use gel material to bond the two connected boards together, even if the gel material with excellent performance is used It is also difficult to achieve lasting connection strength by bonding materials, so cracks appear on the walls of some built buildings. It affects the thermal insu...

AI Technical Summary

Problems solved by technology

For example: when the shrinkage coefficients of the two connected panels are out of sync, tiny cracks will appear between the two panels; the lintel still needs to be lapped to the panels on both sides, and if it is directly connected to the lintel, it is easy to slide down or fall off ; When the slab is connected to the beam, pile, or column, it is difficult for the clip to clamp the stuck side wall of the slab, and small cracks will also appear between the slab and the beam, pile, and column; when the inner wedge-shaped groove is slightly longer, The slurry in the tank is prone to intermittent fracture after solidification

The above defects and deficiencies lead to a good wall still can not be realized
