[0052] This embodiment also provides a construction method of the membrane shell wall installation structure, comprising the following steps:

[0053] S1, measurement, positioning and layout; after the floor concrete reaches the designed strength, clean the joint surface, and have a professional surveyor lay out the measurement and positioning control axis, formwork wall positioning edge line and 200mm control line, and mark them.

[0054] S2, review and correct the lower vertical steel bars 21 of the lower membrane shell wall 2, correct the lower vertical steel bars 21 that do not meet the requirements, and adjust the lower vertical steel bars 21 that are offset in time;

[0055] S3, after the upper membrane shell wall 1 is hoisted and put in place, the diagonal brace assembly is installed; before the hoisting construction, the quality inspector shall check the model and size of the formwork wall. After checking the quality, a special person shall be responsible for hooking. After the hooking personnel evacuate to the safe area, the signalman shall confirm the safety of the components around. After confirmation, a trial hoisting shall be carried out, and the hoisting shall be directed to be slowly hoisted. When the hoisting is about 0.5m from the ground, the safety of the hoisting device shall be confirmed. After confirming the safety of the hoisting device, the hoisting operation shall be continued. When the formwork wall is hoisted to the construction floor 500mm away from the floor, it will be paused for a while. The installer will stabilize the formwork wall against the formwork wall positioning line that has been marked on the floor. After checking that it is qualified, the hook will be slowly dropped to make the position of the formwork wall steel bar close to the position of the lower embedded steel bar. After the formwork wall is in place, two long and short diagonal supports are used to temporarily fix the formwork wall. The diagonal support is mainly used to fix and adjust the formwork wall, ensure the verticality of the formwork wall installation, strengthen the connection between the formwork wall and the main structure, and ensure that the wall does not move during concrete pouring. The inclined floor supports are installed by using pre-buried lifting rings on the floor slab or installing expansion bolts.

[0056] S4, connect and fix the upper vertical steel bars 11 of the upper membrane shell wall 1 and the lower vertical steel bars 21 of the lower membrane shell wall 2; the lower reserved steel bars of the formwork wall can be directly raised to the upper layer by the vertical steel bars of the lower formwork wall, or additional steel bars can be added to connect the vertical steel bars of the upper and lower formwork walls. The upper and lower steel bars of the formwork wall can be connected by binding or mechanical connection. When mechanical connection is used, the mechanical connection joint is in the form of a gold concrete sleeve or a cold extrusion sleeve.

[0057] S5, calibrate the upper membrane shell wall 1, and install the template assembly 8 to obtain the membrane shell wall installation structure. Use the positioning adjustment tool to fine-tune the formwork wall. Adjust the second diagonal brace to adjust the position of the wall, adjust the first diagonal brace to adjust the verticality of the wall, use a crowbar to move the formwork wall, use a plumb bob and a ruler to calibrate the position and verticality of the formwork wall, and use a total station to check. After checking that the horizontal positioning, elevation and verticality of the formwork wall are correct, tighten the diagonal brace assembly and remove the sling clamp.

[0058] Double-sided foam tape is pasted on the contact area between the bottom of the formwork wall and the floor slab. A 200mm wide formwork strip is set at the bottom of the formwork wall as a footboard. The formwork strip is nailed to the concrete floor slab. A 150mm wide formwork strip is nailed above the 200mm wide formwork strip to form a formwork assembly to fix the root of the vertical formwork wall to ensure that the root of the formwork wall does not leak, rot, or deform.

[0059] The construction method of this embodiment adopts a temporary diagonal brace connection method, and connects and fixes the upper and lower membrane shell walls, shortening the shear wall construction time. After the installation is completed, the verticality, elevation, and plane position of the shear wall meet the requirements, and the overall quality appearance is excellent.
