Embodiment 1

[0041] The embodiment of the present invention discloses a construction method for the exterior wall structure of a prefabricated building, refer to figure 1 , including the following construction steps:

[0042] Step 1: Clean up the installation joint surface of the prefabricated outer wall 5 and the installed components, carry out positioning and lay-out on the installation joint surface of the installed components, measure and mark the positioning edge of the prefabricated outer wall 5, use 2 steel bar clamps to The reserved steel bars 11 of the installation components are positioned and checked;

[0043] Step 2: Use the reserved holes 21 on the steel bar fixture 2 to spread the slurry, so that the base surface of the installation joint surface forms a table shape with a convex middle and a concave on both sides;

[0044] Step 3: Install the prefabricated outer wall 5 on the base surface of the installation joint surface, hoist the prefabricated outer wall 5 to the base su...

Embodiment 2

[0050] On the basis of Example 1, increase:

[0051] The cleaning of the installation joint surface includes cleaning oil stains, floating ash and loose concrete blocks, and after the cleaning is completed, the installation joint surface is subjected to water spraying and wetting treatment.

[0052] refer to figure 2 , the two sides between the steel bar clamp 2 and the installed member are padded with square wood 3, the installed member includes a concrete beam 1, and the steel bar clamp 2 passes through the mountain-shaped clamp 4 and the tension bolt 41 is installed in a tight fit with the concrete beam, and the position of the mountain-shaped fixture 4 is adjusted by the bottom positioning rod 42 .

[0053] Before the laser leveler detects the elevation and verticality of the prefabricated outer wall 5, it first marks the fixed height control line on the prefabricated outer wall 5, and adjusts the elevation line of the laser leveler and the fixed height control on the pr...

Embodiment 3

[0058] On the basis of Example 2, increase:

[0059] The installation density of the diagonal braces 6 is determined according to the width of the prefabricated outer wall 5 . If the prefabricated outer wall 5 is wider than 4 meters, use 3-5 diagonal braces 6 , and use 4-6 diagonal braces 6 if the width of the prefabricated outer wall 5 is greater than 6 meters.

[0060] A BIM simulation model is established based on the position information and specification information of the prefabricated outer wall 5, the installation process is simulated, and the structural conflict during installation is checked.

[0061] After the installation of the prefabricated outer wall 5 is completed, the reinforcement bars are bound at the post-casting belt and concrete is poured at the post-casting belt.

Abstract

The invention relates to the technical field of fabricated building construction, in particular to a fabricated building outer wall structure construction method. The construction method comprises the following construction steps that a mounting combination face is cleaned, positioning and paying-off are conducted on the mounting combination face, reserved steel bars of a mounted component are positioned and checked through a steel bar clamp, slurry is spread, the base face of the mounting combination face is in a table shape with the convex middle and the two concave sides, and the prefabricated outer wall is mounted on the base face of the mounting combination face. And elevation and perpendicularity detection is conducted on the prefabricated outer wall through a laser swinger, inclined struts are installed on the side face of the prefabricated outer wall for fixing, and hole filling and grouting are conducted on the prefabricated outer wall. According to the method, the wallboard hoisting and grouting procedures are innovated, traditional extensive construction is converted into fine management, the problems that the flatness and perpendicularity qualification rate of the prefabricated outer wall is low, wall positioning is inaccurate, and grouting quality is not full are solved, the construction efficiency is improved, and the construction period is shortened.

Description

technical field [0001] The invention relates to the technical field of prefabricated building construction, in particular to a method for constructing an outer wall structure of a prefabricated building. Background technique [0002] Prefabricated buildings refer to the transfer of a large number of on-site operations in traditional construction methods to factories, where building components and accessories, such as floors, wall panels, stairs and balconies, are processed and fabricated, and then transported to the construction site. Reliable connection methods are assembled and installed on site. The materials are divided into concrete structure, steel structure and wood structure. [0003] Among them, the installation accuracy of the prefabricated building directly affects the overall firmness of the building, especially the wall panel installation. The wall panel installation generally adopts the form of reserved steel bars corresponding to the plug connection, which inv...
