Description

Wall connectors and building materials wall connectors

This creation system relates to a connection component connected between building materials and walls or ceilings, especially a dry construction connection component.

In the prior art, when installing building materials (plates or columns, etc.) on the wall, if the building materials are heavy or safety is concerned, dry construction is often used to fix the building materials. The common dry construction is to use two L-shaped boards between the wall and the building materials. After they are stacked up and down, a carriage bolt is used to pass through and lock them, so that the building materials are fixed to the wall through two L-shaped plates.

However, such a fixing method is too standardized, and cannot be adapted to various positions, shapes, quantities, and weights of building materials, and a set of the aforementioned connecting components is required to simply correspond to one building material.

In addition, when the weight of the building materials to be installed is too heavy (usually columnar), it is usually necessary to use angle irons extending diagonally upwards to support the weight of the building materials, but the angle irons must first be cut into specific sizes according to site requirements. Then they are welded to each other, resulting in a complex overall structure, which is not only troublesome to install, but also increases the cost.

Therefore, the installation method of the building materials in the prior art needs to be improved.
