However, the practical application of prefabricated composite panels in current housing construction still faces numerous challenges. Traditional composite panels suffer from low splicing precision, prone to misalignment and compromising structural stability; the installation process relies on manual measurement and adjustment, which is inefficient and prone to large errors; and simple overlap joints are often used, resulting in insufficient seismic resistance and integrity, making them difficult to meet the requirements of complex building environments.

[0012] The present invention also provides a method for installing and constructing a composite panel for an assembled building, comprising the following steps:

[0013] Step 1: Before construction, clean and level the foundation components at the construction site. Then, according to the design drawings, open positioning holes corresponding to the positioning pins on the foundation components and perform 3D modeling of the construction site.

[0014] Step 2: Use a lifting device to lift the first plate through the lifting parts, and use the locator to obtain the position of the first plate, convert it into a position in the three-dimensional model, and the lifting device drives the first plate to move until the position obtained by the locator is placed in a fixed position in the three-dimensional model.

[0031] Example 1

[0032] like Figure 1-Figure 3 As shown, the present invention provides an assembled house building composite panel, including a first panel 1 and a second panel 2. The four corners of the lower surfaces of the first panel 1 and the second panel 2 are fixedly connected with positioning pins 5. The positioning pins 5 are used to ensure the position accuracy of the panels during installation to avoid misalignment. A conical rubber sleeve is sleeved on the positioning pins 5. The conical rubber sleeve can reduce the hard collision between the positioning pins 5 and the positioning holes during lifting and splicing, and can make the positioning pins 5 fit with the positioning holes to ensure the sealing of the connection between the basic components and the panels.

[0033] The upper surfaces of the first plate 1 and the second plate 2 are both provided with a hoisting member 3 and a locator 4. The first plate 1 and the second plate 2 are connected to the lifting device via the hoisting member 3. The hoisting member 3 is fixedly connected to the first plate 1 and the second plate 2. There are two sets of hoisting members 3, which are symmetrically arranged at both ends of the upper surfaces of the first plate 1 and the second plate 2. The hoisting members 3 are used for vertical transportation and positioning installation of the plates to achieve precise displacement. The locators 4 are symmetrically provided at the four corners of the upper surfaces of the first plate 1 and the second plate 2. The locators 4 are detachably connected to the first plate 1 and the second plate 2. The locators 4 are used to interact with the three-dimensional modeling software and the control system to obtain the actual position of the first plate 1 and the second plate 2 in space, and convert them into three-dimensional model coordinates to assist in adjusting them to the designed position.

[0034] A first positioning assembly is fixedly provided in the middle of the upper surface of the first plate 1, and a second positioning assembly is fixedly provided in the middle of the upper surface of the second plate 2. The first positioning assembly includes a first positioning column 6 and a first connecting hole 7 opened in the middle of the first positioning column 6, and the second positioning assembly includes a connecting plate 8, a connecting steel bar 9 fixedly connected to the connecting plate 8, a second positioning column 10 and a second connecting hole 11 opened in the middle of the second positioning column 10, and the connecting steel bar 9 is an inverted "U" shape. When the second plate 2 is lowered, the connecting steel bar 9 above it is inserted into the first connecting hole 7 to realize the positioning and splicing of the first plate 1 and the second plate 2 in the vertical direction. The connecting steel bar 9 is inserted into the first connecting hole 7 of the first plate 1, and forms a "steel bar-hole" locking structure with the first positioning column 6, forming a rigid connection after pouring.

[0035] A first retaining protrusion 12 is fixedly mounted on the left side of the first plate 1, with a first through-hole 13 defined in it. A first retaining groove 14 is defined on the right side of the first plate 1, with a first retaining steel bar 15 fixedly positioned in the middle of the first retaining groove 14. When adjacent first plates 1 are joined, the first retaining protrusion 12 of the second first plate 1 is inserted into the first retaining groove 14 of the first first plate 1 to prevent lateral misalignment. The first retaining steel bar 15 of the first first plate 1 is inserted into the first through-hole 13 of the second first plate 1, forming a steel bar connection and enhancing the lateral rigidity of the plate surface after casting.

[0036] A second limiting protrusion 16 is fixedly mounted on the left side of the second plate 2, with a second through-hole 17 defined in the second limiting protrusion 16. A second limiting groove 18 is defined on the right side of the second plate 2, with a second limiting steel bar 19 fixedly mounted in the second limiting groove 18. The transverse splicing principle between the second plates 2 is the same as that for the first plates 1, ensuring the connection accuracy and strength of the second horizontal row of plates.

[0037] The present invention also provides a method for installing and constructing a composite panel for an assembled building, comprising the following steps:

[0038] Step 1: Before construction, clean and level the basic components of the construction site. Then, according to the design drawings, open positioning holes corresponding to the positioning pins 5 on the basic components, and perform three-dimensional modeling of the construction site. The locator 4 and the three-dimensional modeling software are electrically connected to the control system. The locator 4 can be laser positioning or GPS, etc. Its data transmission method and the algorithm logic of the control system are all existing technologies, so they are not elaborated in detail.

[0039] Step 2: Use a lifting device to lift the first first plate 1 through the lifting part 3, and obtain the position of the first plate 1 through the locator 4, convert it into the position in the three-dimensional model, and the lifting device drives the first plate 1 to move until the position obtained by the locator 4 is placed in a fixed position in the three-dimensional model, and then lower the first plate 1 until the positioning pin 5 at the bottom of the first plate 1 is inserted into the positioning hole on the foundation component. The first vertical row of the first plate 1 and the second plate 2 are not provided with the first positioning column 6 and the second positioning column 10 on the left side to prevent the existence of pores and affect the casting quality, and the first limiting groove 14 and the second limiting groove 18 opened on the right side of the first plate 1 and the second plate 2 can be filled during casting, and are respectively provided with a first limiting steel bar 15 and a second limiting steel bar 19 inside to enhance their strength.

[0040] Step 3: Lift the second first plate 1, repeat the steps in step 2 until the first plate 1 is placed in a fixed position on the three-dimensional model, and slowly lower the first plate 1. During the lowering process, the first limiting protrusion 12 of the second first plate 1 is gradually inserted into the first limiting groove 14 of the first first plate 1, and the first limiting steel bar 15 of the first first plate 1 is inserted into the first through hole 13 of the second first plate 1. Repeat all the above steps until the first horizontal row is fully spliced;

[0041] Step 4: Use the lifting device to lift the second plate 2, obtain the position of the second plate 2 through the positioner 4, and when the second plate 2 is moved to the fixed position in the three-dimensional model, lower the second plate 2. During the lowering process, one end of the connecting steel bar 9 of the second plate 2 is inserted into the first connecting hole 7 of the first plate 1, and the positioning pin 5 at the bottom of the second plate 2 is inserted into the positioning hole to complete the splicing. Then, lift the second second plate 2. The connection operation of the two second plates 2 is the same as the connection operation of the two first plates 1, until all the second horizontal rows are spliced together;

[0042] Step 5. Repeat step 3 from the third row to the last row until all the splicing is completed. Remove the positioner 4 from the first plate 1 and the second plate 2, and lay the steel bars using the laying method in the existing technology, cast them, and finally complete the construction.

[0043] Therefore, the present invention adopts the above-mentioned prefabricated house building composite panel and installation construction method, and realizes high-precision positioning, firm connection and efficient construction of composite panel installation through structural designs such as positioning pins, tapered rubber sleeves, limiting grooves, positioning components, etc., in conjunction with three-dimensional modeling and automatic positioning of the positioner, which not only effectively improves the overall seismic resistance and stability of the structure, but also reduces manual intervention, reduces construction errors and safety hazards, significantly improves construction efficiency, reduces costs, and promotes the development of prefabricated building technology towards a greener and smarter direction.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the same.
