Stone curtain wall construction method

Abstract

The invention discloses a stone curtain wall construction method, which comprises the following steps of: 1) arranging a main joist on a structural wall; 2) arranging a sub-joist on the main joist; 3) arranging a dry-hanging fitting on the sub-joist, wherein the dry-hanging fitting is a tin-coated steel piece and comprises a horizontal web, a vertically downward plugboard and a vertically upward baffle plate, which are formed at one time, the plugboard is arranged at the front end of the web, the baffle plate is arranged on the middle front part of the web, the web is provided with a mounting slot hole; and the slot hole is positioned behind the baffle plate; and 4) arranging stone slabs of which the upper parts are provided with notches layer by layer upwards in turn from the bottom of the curtain wall, wherein the plugboard is inserted in the notch of the below stone slab, the lower end of the upper stone slab is positioned at the front end of the web, the baffle plate limits the stone slab and controls the verticality of the stone slab, the stone slabs are adhered to the dry-hanging fitting through a structural adhesive, foam strips are inserted at the periphery of each stone slab and a sealant is used for caulking. The method facilitates the maintenance of the curtain wall.

Description

technical field [0001] The invention relates to a construction method of a building decoration curtain wall, in particular to a construction method of a stone curtain wall. Background technique [0002] As the progress of urban construction and development is accelerating day by day, various construction methods and related building materials and decorative materials have entered the market one after another, which has changed the appearance of the city with each passing day. my country has become the world's largest producer and user of building curtain walls, and the use of stone curtain walls has occupied a considerable proportion, becoming an indispensable part of building interior and exterior wall decoration. [0003] Stone installation is an important part of stone curtain wall construction. At present, the overhead dry-hanging method is used for installation. There are many types of pendants used, mainly pin-pin type, butterfly type (commonly known as up and down, ...

AI Technical Summary

Problems solved by technology

At present, there is still a kind of SE-type pendant, although it overcomes the above shortcomings, but because the structure of this pendant is relatively complicated, it is not easy to process, and the production cost is high

Moreover, the SE-type pendant is a component type, and the connection between the stone and the unit pendant needs to be processed in the factory in advance. The on-site processing ability is poor, and it lacks integrity and versatility, so it cannot be recognized by the market.

More importantly, after the curtain wall is installed, except for the SE-type pendant, the stone cannot be disassembled at will. No matter which stone needs to be dismantled, the stone above it must be removed first. The lower the stone needs to be dismantled, the greater the project volume. Inconvenient repair and maintenance
