[0002] During the curtain wall construction process, in order to provide an installation foundation for the curtain wall keel, it is often necessary to carry out prefabricated embedded plates or post-embedded plates for construction. When prefabricated embedded plates are used, the main structure reinforced concrete must be poured together for construction, which is complicated and can easily cause the prefabricated embedded plates to deviate during pre-embedding or pouring of concrete.

[0003] When using post-embedded plates, chemical anchor bolts are usually used to fix the post-embedded parts directly on the main structure at the corresponding position, and then welding is used to weld the supporting parts of the vertical keel (vertical frame) of the curtain wall to the prefabricated embedded plate to achieve the fixation and installation of the supporting parts. However, welding is affected by the welding level and welding process of the workers, which is easy to cause welding quality problems such as wrong welding, leaking welding, and incomplete welds, which seriously affects the construction quality of the embedded parts. Due to the influence of measurement and layout and the main structure steel bars, post-embedded parts often appear offset or need to be adjusted in installation position and angle. How to ensure the accuracy of the installation position, avoid direct welding to damage the post-embedded plate, improve the shear deformation resistance of the embedded parts, and ensure the safety, stability and shear resistance of the curtain wall keel has become an urgent problem to be solved.

[0025] The embedded plate 1 has an appearance of a back plate shaped like a rectangular parallelepiped, with symmetry on both sides and a groove formed on the reverse side of a central protrusion. One section of the protrusion is a connecting section 3, and two elliptical long holes 5 are provided on the connecting section 3. Both ends of the connecting section 3 are fixed sections 4, and two groups of adjustment holes 7 are provided on the fixed section 4. The detachable support plate 2 is connected and fixed through this embedded plate 1.

[0027] There are two groups of adjustment holes 7, namely transverse adjustment holes and vertical adjustment holes. The transverse adjustment holes and vertical adjustment holes are long holes and perpendicular to each other. The transverse adjustment holes and vertical adjustment holes cooperate with each other to achieve the adjustment of the anchor position in two different dimensions (transverse and vertical), thereby reducing measurement and installation errors and ensuring installation accuracy.

During actual installation, the installation angle of the detachable support plate 2 can be finely adjusted by adjusting the relative angle between the elliptical inclined hole 10 and the elliptical long hole 5.

[0031] Step 2: Measure and lay out the structure, and make holes for fixing bolts. Workers use professional hole-making tools (electric drills) to make and clean holes. The location and size of the holes must meet the size and depth requirements of the fixing bolts.

[0032] Step three, use chemical anchors or expansion bolts to fix the embedded plate to the main structure, and use the anchor transverse adjustment holes and anchor vertical adjustment holes to cooperate with each other to achieve the adjustable position of the embedded plate, ensure installation accuracy, and preliminarily eliminate measurement and construction errors.

[0033] Step 4: Use the installation holes and the long elliptical holes on the embedded plate to install and fix the support plate on the embedded plate, and use the long elliptical holes to adjust the position of the detachable support plate, thereby further eliminating the effects of structural, measurement errors, and construction errors on the installation quality.
