Construction Skill plan

(1) The installation method of this project burst wall board is (embedded) horizontal installation, the first choice of hook head bolt connecting angle steel node device node. (Thickness: 100mm, b05 a3.5)

(2) Construction Technology:

External Wall: bullet line lofting-set horizontal control line and straight control line-cultivation buried iron 600 expansion bolt-place buried iron @-through long Angle Steel 60*6, welding manufacturing and rust prevention disposal ---- plate appearance ----- view and check sheet ------ hoisting sheet ----- Welding Device of angle steel reinforced at the window hole ----- view of weld ----- paint of anti-rust paint ------ calibration plane and straight degree ----- fixed accessories ------ repair, sewing ----- glue filling disposal.

(3) construction method:

A) according to the drawing requirements, the flat line and horizontal control line of the device for constructing the floor, frame column, and girder are used to control the straight, flat, and elevation of the window holes. Test the leakage wall hole reserved for civil engineering. If there is any error in civil engineering correction, make a record.

B) based on the scale requirements of the construction drawing and layout map, the flat line and horizontal control line of the wall panel are used as the basis, cultivation of 600 expansion bolts on the side of the pillar @ (embedded plate, construction of the column side is not preset embedded, fixed embedded with expansion bolts) device buried iron, welding through angle steel, the weld quality of the welding device for angle steel reinforced by the welding window holes of the window direction control line should be carried out in accordance with the requirements of the "steel construction quality inspection standards. The appearance should reach the external surface without pores, no external surface slag, no biting side and no cracks and other needs, to achieve even fullness without loss. Welding should meet the planning requirements, welding should be knocked out after welding appearance of welding slag, check the welding quality, to meet the needs of the next process can be Rust Paint painting. Through the long angle steel and support parts of the device must be based on the device Plane Orientation of the plate wall and the horizontal height of each layer of the plate wall to welding ability to ensure that the horizontal seams of the plate device level and Plane flat.

C) The plate is transported by the factory to the site by car, and the quality of the plate is checked and checked according to the standards and quantity of the on-site delivery, plate quality inspection in accordance with China's national sand Aerated Concrete Plate inspection "GB15762-1995" rules. On the Formation of plate corner damage in the transportation, according to the need to use Kaiyuan special repair material (KY-XB-01) for Corner repair, in principle before the device first check the Board damage orientation and degree of damage, dispose of damage that affects the structural endurance of the sheet. Clean the base layer of the damaged part of the sheet during repair. The thickness of each repair should not exceed 7mm, after the repair is completed, the steel tooth grinding plate and sand grinding plate are used to correct the appearance scale after the repair material strength reaches. The edge in the Process of the plate device is damaged, and the device can be repaired after completion. Do not pollute the surrounding wall during the repair.

D) after the plate is checked and checked, the crane on site or the crane on the car is unloaded according to the plate standards required by each wall. During unloading, the maintenance plate should be paid attention, avoid board damage during unloading. Each sheet is mounted to the wall with a sling. Adjust the flatness and directness of the sheet surface based on the wall surface device control line and horizontal transverse joint control line, and then use a wooden joint to temporarily fix the wall panel, according to the planning requirements, drill in the direction of the bolt device and place the hook head bolt through the hook head bolt to fix the wall panel on the angle steel plane connected to the bolt. (When the first wall panel Device on each floor is used, the horizontal elevation is properly controlled ).

E) according to the planning requirements, angle steel should be used to reinforce the opening of the upper and lower wall window holes. The horizontal angle iron (in the same direction as the plate) of the window holes should be welded and fixed with the buried parts next to the column, vertical angle steel and transverse angle steel welding, device orientation and welding quality should meet the planning requirements, the weld should be plump, uniform, no pores, cracks and other welding defects. After the self-check welding quality reaches the requirement and the welding slag is eliminated, the supervisor should check the quality and then brush the rust-proof paint. (The angle steel should be embedded in the plate and flat with the plate, and fixed with a hook head bolt ).

F) The wall panels of the device should be properly protected during transportation, and each wall panel should be hoisted by electric hoist, small-scale hoist, and other lifting equipment, use nylon sling to fix the wall panel during hoisting. When installing the panel, pay attention to the corner of the wall panel and do not damage it.

G) Check the flatness of the Board with a 2 m Ruler, and verify the smoothness and water level based on the straight line and horizontal line, so that the device error control of the board is within the promised error range.

H) after each sheet is verified, the connecting parts of the sheet can be fixed.

I) after all the wall panel devices are completed, check the quality of the wall mounted devices. Correct the wall surface with steel tooth or sand plate exceeding the promised error. For the lack of corner wall board with open yuan special (KY-XB-01) repair material for repair. Only after passing the self-check and inspection by the supervisor can the next process such as gluing be carried out.

J) correct and organize the seams before applying sealant, for the parts with different slit width, use the ink line to pop up and correct the line, and then use the portable switch to start and cut the cut regular (use the special cutting material to open the yuan to repair the smooth corner), and connect the parts with the structure (horizontal and vertical) fill in the seams with fireproof rock wool, fill in depth out of the panel surface 10mm deep, fill needs to be dense, before gluing, You need to tidy up the dust inside the Board seams and other garbage, use special sealant bottom brush rubber seams, wait for the bottom to be coated with dry solid and then use a glue gun to inject the sealant into the plate joint. After each glue is exhausted, use a batch of glue knives to promptly batch split the seams. However, the sealant shall not pollute the wall surface, and the remaining Glue should be sorted in time, after the sealant is prepared, pay attention to the maintenance of the product to avoid damage to the smoothness of the rubber surface and cleaning of the contaminated rubber surface. It is prohibited to perform gluing operations in rainy places. K) Report to the supervisor for inspection after self-check is completed for all devices.
