Home loft production Beijing steel structure production

Beijing Xiangrui Tongda specializes in the production of steel structure lofts, family lofts, steel-concrete structure lofts with additional floors, steel-wood structure lofts, staircase steel structures, and ceramsite concrete cast-in-place lofts. Undertake large-scale workshops and outdoor steel structure additions and roofing projects. We have many years of production experience, strong strength, and professional designers for on-site measurements.
The prerequisite for building a loft: there must be sufficient floor height. Generally speaking, the lower edge of the floor slab of a new attic in a duplex house is level with the lower edge of the floor slab of the original first floor. The lower edge of the single-story attic floor slab shall not be less than 1 meter. The inner clear height of the attic floor and roof shall not be less than 1 meter, and the minimum height shall not be less than 1 meter. This is based on the premise that there are people living in it. If your attic is not occupied by people, then you can decide the height at will.

One main material: I-beam, rebar, wire rod, floor deck expansion bolt, special anti-rust coating for steel structure, light body ceramsite cement, etc.
Second process flow:
Determine the actual elevation of the embedded parts, determine the actual elevation of the site (determine the length of the main beam and secondary beams), frame (contact) processing, fix the main beam, fix the secondary beam, fix the plate, weld the steel mesh to reinforce the light body ceramsite The main structure of concrete pouring shall be inspected for rust removal and rust prevention (fire prevention).

Three construction specifications:

Determine the embedded parts: first remove the wall covering and expose the embedded parts to determine their specific location and size, and make the cutting connection of the main beam. When removing the wall covering, follow the markings on the original wall to avoid unnecessary shedding of the wall covering. The embedded parts should be in accordance with the design requirements.

On-site elevation determination: The elevation is determined based on the specific location of the embedded parts. If the site elevation is different from the original design, the company's design department must be consulted. Construction can only be carried out after the secondary design plan is finalized, and the site elevation must be marked with a horizontal line.

Main beam frame (joint) production: The frame is made of angle steel as the main material, and expansion bolts are used to fix the embedded parts and fix the point spacing.

The exact length of the main beam has been measured on site, and the error is measured one beam at a time, and then a data book is created, and the materials are cut uniformly according to the data book. The secondary beam is determined according to the main beam spacing, and its error.
