Detailed explanation of construction scheme of membrane structure garage

I believe everyone has seen the carport, and many units or public places will install carports for people to park their cars. There are membrane structure garages, steel structure garages, etc. Today, we will mainly study the lower membrane structure garage. Membrane structure is relatively light and unique in shape, so many parking lots and waiting rooms now choose to use membrane structure. Like the steel carport, it can play a good role in wind, rain and sun protection, but it is much lighter than the steel structure. Let's take a look at the construction scheme of membrane structure carport.

1. Processing preparation and blanking: setting out according to the construction drawing. When marking materials, the welding shrinkage and machining allowance shall be reserved, and samples shall be made according to the marking. Steel correction: steel must be corrected before blanking, and the corrected deviation value shall not exceed the allowable deviation value specified in the specification to ensure the blanking quality. Hot-worked steel should be hot-worked first, and then drilled after cooling. Cutting, drilling and spraying antirust paint on steel plate embedded parts.

2. Measuring and setting-out: Measure the elevation center line of embedded parts according to the civil elevation datum line, and check the elevation deviation and left-right deviation of embedded parts. Sort out the results and determine the adjustment and treatment scheme for the separation of embedded parts. Determine the top elevation line of embedded parts along the outer edge of the floor with the pop-up ink line.

3. Installation and treatment of embedded parts: locate the installation position of embedded parts and drill holes for installation. Require accurate position of embedded parts and firm embedding. The elevation deviation is not more than 9mm, and the left-right displacement is not more than 20mm.

4. Installation and welding of the boom: the boom is installed by welding, and the welding nodes need to be checked, and the design slope of the boom needs to be adjusted before welding. After one boom on one side is accurate, install the other boom on the other side, and spot weld it after it is in place accurately. Then, based on these two booms, draw the highest and lowest elevation lines of the booms and weld the remaining booms one by one. And weld seamless steel pipes.

When the section steel needs to be extended, weld the joint first and straighten it. When using reinforced joints, in order to make the joint reinforced close to the steel plate embedded parts, the corners should be shoveled off according to the design requirements. Butt welds shall be welded with arc plates at both ends of the weld, and the materials and groove types are the same as those of weldments. After welding, it should be cut off by gas cutting and ground flat.

5. Calibration check: After the boom is installed, first check the quality of the connecting parts on site. The installation quality of the boom mainly checks the verticality of the vertical plane of the boom; The vertical surface side of the cantilever sinks under pressure; Slope of suspension arm. Ensure that the suspension arm meets the design stress state and overall stability requirements.

6. Connect the stay cables: locate the reference line and elevation line of the stay cables, install the embedded parts as required, and weld the railings.

7. Installation and welding of stainless steel glass claw: pop up vertical and horizontal lines and design elevation according to the design size, clamp with fixture, spot weld, and weld the glass claw seat after assembly.

8. Anti-rust coating treatment: remove welding slag and spatter, spray white paint on the stainless steel surface of membrane structure awning, and carry out multiple anti-rust coating treatment. The thickness of coating and paint film shall meet the design requirements or the provisions of construction specifications. Do not leave out the paint on the inside of the limb steel.

9. Processing, manufacturing and installation of laminated glass: the glass size and its horizontal and vertical positions are determined according to the design requirements and measured dimensions, and the glass is processed and manufactured by the manufacturer. Install stainless steel glass claws, and adjust the glass after temporary fixation. The adjustment standard is horizontal, flat and vertical. The deviation shall not exceed the specified deviation.

10. Adjustment inspection: conduct overall adjustment inspection on the spotted glass, and the adjustment standards are horizontal, vertical and flat. The deviation shall not exceed the specified deviation.

1 1. gluing: thoroughly clean the gaps between the glasses, and the sunshade of the membrane structure shall be free of water, grease, paint, rust, cement mortar and dust. Clean the bonding surface completely and dry it. In order to adjust the depth of the joint and avoid three-sided adhesion. Stick protective tapes on both sides of the joint to protect the glass from pollution. Apply sealant from top to bottom at the same time. After glue injection, smooth the surface of glue joint to remove excess glue. Tear off the protective paper after glue injection, and wipe the glass with solvent if necessary. Don't be contaminated with dust and scratches until the glue is completely hardened.

12. Repair inspection: local repair inspection.

13, glass cleaning: cleaning glass dirt as a whole. If necessary, wipe the glass with solvent.

14. Clearing the site: protecting and cleaning the site.

15, completion acceptance: completion acceptance.

Well, the above steps are the construction step scheme of the whole membrane structure carport, which can be referenced by relevant staff. The above steps must be completed in each step to build a qualified carport. For those who use it, quality is the most important. In addition, when installing the membrane structure carport, we should also follow the national standards and cannot change it at will. Only in this way can the construction personnel be restrained and the most qualified membrane structure carport be built for customers.
