Description

Technical Field

[0001] This invention belongs to the field of building engineering, specifically a method for installing embedded prefabricated exterior wall panel components. Background Technology

[0002] Prefabricated modular buildings meet the requirements of building industrialization and green environmental protection. Especially with my country's industrial policies on green building and building industrialization, the demand for prefabricated modular buildings is increasing. The installation of prefabricated exterior wall panels is one of the main contents of prefabricated modular building construction. Currently, prefabricated exterior wall panels generally adopt an embedded installation design. The installation of large prefabricated exterior wall panel components such as PC and AAC panels requires the use of large machinery due to their size and weight. In the case of an embedded design, since there are beams above the prefabricated exterior wall panel components, there is currently no way to insert the prefabricated exterior wall panel components under the beams. Therefore, the common practice is to install the prefabricated exterior wall panel components before the construction of the upper floors (i.e., simultaneous construction of the main structure). However, this method seriously interferes with the existing procedures and work surfaces of the main structure construction, resulting in extended construction period and reduced efficiency. Therefore, there is an urgent need for a method that allows for the embedded installation of prefabricated exterior wall panel components after the main structure construction. Summary of the Invention

[0003] Embedded installation of prefabricated exterior wall panels is a standard architectural engineering term referring to the installation of prefabricated exterior wall panels within the space enclosed by beams and columns on upper and lower floors. Sometimes, the sides of the prefabricated exterior wall panels are not columns, but other walls; the upper and lower parts may be beams or floor slabs.

[0004] The purpose of this invention is to provide an installation method for embedded prefabricated exterior wall panel components to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An installation method for embedded prefabricated exterior wall panel components includes an upper floor structure, a lower floor structure, prefabricated exterior wall panel components, and connectors. The upper floor structure is a beam or floor slab, and the lower floor structure is a floor slab or beam. The prefabricated exterior wall installation method includes the following steps. This installation method can be applied to installation from the outdoor side or installation from the indoor side when the indoor floor slab has not been constructed.

[0007] Step 1: Use lifting equipment to lift the precast exterior wall panel components at a certain angle to the vertical direction until the top of the precast exterior wall panel components is close to and lower than the bottom of the upper floor structure. The main purpose of lifting the precast exterior wall panel at a certain angle is to facilitate the extension of the upper end over the upper floor structure in Step 2. If it is installed from the indoor side, the vertical height of the precast wall panel after tilting must be smaller than the net clearance of the top of the upper and lower floor structures.

[0008] Step 2: Guide the upper end of the prefabricated exterior wall panel component into or through the beam below the upper floor structure; lift the prefabricated exterior wall panel component as needed until the lower end of the prefabricated exterior wall panel component is higher than the top surface of the lower floor structure.

[0009] Step 3: Guide the lower end of the precast exterior wall panel component to the installation position above the lower floor structure; lower the precast exterior wall panel component and place it on the lower floor structure; continue to lower the precast exterior wall panel component and adjust it to be vertical; when guiding the lower end of the precast exterior wall panel component to the installation position, the lifting sling will be on the other side of the precast exterior wall panel component and in contact with the upper floor structure to bear the force, which can be used to pull the precast exterior wall panel component straight and vertical.

[0010] Step 4: Connect and secure the connectors to the precast exterior wall panel components, and remove the lifting equipment.

[0011] The connecting component is a connecting plate or embedded part fixed to the upper floor structure and the lower floor structure; or the connecting component is a connecting plate or embedded part fixed to the lower floor structure; or the connecting component is a temporary diagonal brace fixed to the lower floor structure.

[0012] The beneficial effects of this invention are: it solves the current problem of embedding and installing prefabricated exterior wall panel components, especially large PC and AAC exterior wall panels, after the main structure construction. This greatly simplifies the construction process and improves construction efficiency. Attached Figure Description

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0015] Please see Figure 1 In this embodiment of the invention, the structure includes an upper floor structure 2, a lower floor structure 3, prefabricated exterior wall panel components 1, and connectors fixed to the lower floor structure 3. The upper floor structure 2 is a beam or floor slab, and the lower floor structure 3 is a floor slab surface or beam top. The connectors are temporary diagonal braces 11. This embodiment is installed from the outdoor side. Installation is carried out according to the following steps and methods:

[0016] Step 1: Reference Figure 1In step ①, the prefabricated exterior wall panel component 1 is lifted at a certain angle to the vertical direction using a lifting device until the upper end of the prefabricated exterior wall panel component 1 is below the upper floor structure 2. The lifting device is a tower crane.

[0017] Step 2: Reference Figure 1 In step ②, the upper end of the prefabricated exterior wall panel component 1 is pulled in and extended into the upper floor structure 2 using the hook 10; then the prefabricated exterior wall panel component 1 is lifted until the lower end of the prefabricated exterior wall panel component 1 is higher than the top surface of the lower floor structure 3.

[0018] Step 3: Reference Figure 1 In step ③, the lower end of the precast exterior wall panel component 1 is pulled into the installation position above the lower floor structure 3 using the hook 10; the precast exterior wall panel component 1 is lowered and placed on the lower floor structure 3; the precast exterior wall panel component 1 is continued to be lowered, and the angle of the precast exterior wall panel component 1 is adjusted to make it vertical. When the lower end of the precast exterior wall panel component 1 is guided to the installation position, the first lifting sling 5 will be located on the other side of the precast exterior wall panel component 1 and will be in contact with the upper floor structure 2 to bear force. This force can be used to pull the precast exterior wall panel component 1 straight and vertical.

[0019] Step 4: Reference Figure 1 In step ④, the temporary diagonal brace 11 of the connector is connected and fixed to the upper and lower ends of the precast exterior wall panel component 1 respectively; then the first lifting sling 5 is removed to complete the installation.
