Hard polyurethane foamed wall-sticking stone material veneering construction method

Abstract

Firstly, cleaning base surface of building and stone veneer, prepositioning on the wall body, preparing working slurry liquor in-situ, and using the hard polyurethane foamed working slurry liquor to making veneering construction of stone veneer along the prepositioned position, then pointing and cleaning surface.

Description

Technical field [0001] The invention relates to a construction technology of building materials, in particular to a construction technology of stone veneer for wall surfaces, and belongs to the technical field of building construction. Background technique [0002] In the prior art, the marble or granite stone veneer of the building is generally applied by the hanging method and the dry hanging method. [0003] When the hanging method is adopted, the angle iron or rebar fixing frame should be fixed on the wall first, and the metal pendant should be installed on the fixing frame, then cement mortar is filled between the fixing frames, and then the stone veneer is pasted. The stone veneer is pasted on the wall by cement mortar. At the same time, the stone veneer is fixed by a fixing frame and metal pendants, and then grooves are made to deal with the gaps between the stones so that rainwater will not seep into the gaps. Between the stone and the wall. [0004] Its shortcomings are:...

Problems solved by technology

[0004] Its disadvantages are: firstly, during construction, the cement is required to be high-grade high-strength cement, and a large amount of steel is required to fix the stone veneer, which is costly; secondly, when the quality of the groove is not high or the cement mortar is not pasted enough, Rainwater easily penetrates between the stone and the wall. When the weather is cold, the rainwater freezes and expands in volume, which can cause local warping of the stone veneer. In severe cases, the entire stone veneer may fall off; Slurry back will form irregular alkali spots on the surface of the stone veneer, which will damage the surface gloss of the stone veneer and affect the appearance of the building

[0006] The disadvantages of this construction method are: First, because the stone veneer is only in contact with the fixed frame by the grooves around it during installation, the inner surface of the stone veneer has no contact with the wall and the fixed frame, and the stone veneer has no contact with the wall and the fixed frame. In this way, the brittle stone veneer can be damaged and fallen off, which is difficult to repair and has great potential safety hazards; second, because the weight of all the stone veneer is borne by the fixing frame, more steel is needed than the hanging method; third , the construction is difficult, the construction precision is high, the welding workload is large, labor-intensive, and consumables are required, which makes the project expensive and costly.
