Description

Technical Field

[0001] This utility model belongs to the field of ACC wall auxiliary tooling technology, specifically relating to an ACC exterior wall panel auxiliary installation device. Background Technology

[0002] With the development of the construction industrialization, more and more companies are starting to research and produce prefabricated wall panels, breaking them down into multiple modules and processing them into semi-finished products in factories, such as ACC exterior wall panels. Currently, ACC exterior wall panels generally have embedded parts set in the wall surface, and then the ACC exterior wall panels are fixed by hooks or expansion screws. After that, waterproofing is done and the exterior wall is painted. When installing ACC exterior wall panels, a crane is required to assist, and the embedded parts and the connecting parts on the ACC wall are matched to achieve positioning, and then hooks or screws are used. This positioning method is relatively complex and requires a lot of time for calibration. In order to solve this problem, this solution was developed. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide an auxiliary installation device for ACC exterior wall panels, which can assist in positioning the ACC exterior wall panels during installation.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an ACC exterior wall panel auxiliary installation device, including a positioning plate, a cross-shaped limiting protrusion is provided on the outward side of the positioning plate, the extension line of the midpoint of the limiting protrusion extending toward its surface coincides with the extension line of the midpoint of the positioning plate extending toward its surface, a pre-embedded plate is formed on the back of the positioning plate, and at least two connecting holes are provided on the surface of the positioning plate.

[0005] Furthermore, the number of embedded plates is two, and they are arranged one above the other.

[0006] Furthermore, the limiting protrusion divides the positioning plate into four quadrants, and the number of connecting holes is four, each located in one of the four quadrants.

[0007] An ACC exterior wall panel auxiliary installation device includes a positioning plate and a pre-embedded column. The positioning plate has a cross-shaped limiting protrusion on its outward side. The extension line of the midpoint of the limiting protrusion towards its surface coincides with the extension line of the midpoint of the positioning plate towards its surface. The pre-embedded column is located on the back of the positioning plate. The positioning plate can rotate around the axis of the pre-embedded column.

[0008] Furthermore, the limiting protrusion is provided with a first countersunk hole in the middle, the embedded column is provided with a threaded hole on its surface, and the positioning plate and the embedded column are connected by a connector passing through the first countersunk hole and screwed into the threaded hole.

[0009] Furthermore, the connector includes a locking part, a connecting part, and a threaded part, which are connected sequentially. The locking part and the connecting part are located in the first countersunk hole, and the threaded part has an external thread. The threaded part is adapted to the threaded hole.

[0010] Furthermore, the positioning plate is provided with multiple pre-drilled holes, and the vertical projection of the pre-drilled holes coincides with the vertical projection of the surface of the embedded column.

[0011] Furthermore, the positioning plate is positioned by passing through a pre-drilled hole and being screwed into the pre-embedded column via a limiting member.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model involves installing four matrix-set positioning plates on the wall and adjusting their horizontal and vertical alignment. Pre-embedded plates extend into the wall, and expansion screws lock the connection holes to the wall. The area formed by the upper limit protrusions of the four positioning plates matches the shape of the ACC exterior wall panel. The ACC exterior wall panel is then embedded between the four limit protrusions, and the screws are tightened. This method allows for fast installation and eliminates the need to adjust the horizontal alignment of the ACC exterior wall panel, as the horizontal alignment between the four limit protrusions is already adjusted during the installation of the four positioning plates.

[0014] 2. Because the pre-embedded holes cannot perfectly match the pre-embedded columns, there may be some offset on the positioning plates, causing the limiting protrusions to shift. As a result, the area enclosed by the upper limiting protrusions of the four positioning plates cannot be matched with the ACC exterior wall panel. This utility model provides an auxiliary installation device for ACC exterior wall panels. By pre-embedding the pre-embedded columns of the positioning plates in a matrix setting into the wall, the horizontal and vertical alignment of the positioning plates is adjusted by rotating the positioning plates. After adjustment, a drill bit is used to drill through the pre-drilled holes to form connecting screw holes on the surface of the pre-embedded columns. Then, screws are inserted through the pre-drilled holes and screwed into the connecting screw holes to achieve horizontal and vertical positioning of the positioning plates. Finally, the positioning plates are fixed by screwing expansion screws through the connecting holes into the wall, and then the ACC exterior wall panels can be installed. Attached Figure Description

[0023] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0024] Example 1

[0025] like Figures 1-4 As shown, this embodiment provides an auxiliary installation device for ACC exterior wall panels, including a positioning plate 1.

[0026] The positioning plate 1 has a cross-shaped limiting protrusion 11 on its outward side. The extension line of the midpoint of the limiting protrusion 11 to its surface coincides with the extension line of the midpoint of the positioning plate 1 to its surface. The surface of the positioning plate 1 has a connecting hole 13, which is a countersunk hole. Specifically, the limiting protrusion 11 divides the positioning plate 1 into four quadrants 111, and there are four connecting holes 13 located in the four quadrants 111 respectively.

[0027] An embedded plate 12 is formed on the back of the positioning plate 1. The embedded plate 12 is used to extend into the wall 31. When the positioning plate 1 is installed with the ACC exterior wall panel 3 under stress, the load-bearing force is transmitted to the wall through the embedded plate 12.

[0028] Preferably, there are two embedded plates 12 arranged vertically, and the number of embedded plates 12 can be selected according to the weight of the ACC exterior wall panel 3.

[0029] The ACC exterior wall panel 3 in this solution includes a wall 31, and a surrounding frame 32 is provided around the wall 31. The surrounding frame 32 is used to abut against the surface of the limiting protrusion 11. When multiple ACC exterior wall panels 3 are assembled between multiple positioning plates 1, the surrounding frame 32 can cover the outer surface of the limiting protrusion 11, making the overall appearance more aesthetically pleasing.

[0030] Working principle: Four matrix-set positioning plates 1 are installed on the wall 31, and the horizontal and verticality of the four positioning plates 1 are adjusted. The pre-embedded plates 12 are inserted into the wall 31, and the connection holes 13 are locked to the wall 31 with expansion screws. If, during the adjustment process, a gap is found between the pre-embedded plates 12 and the adapter holes on the wall 31, causing the positioning plates 1 to tilt, this is solved by placing shims in the adapter holes. During installation, the ACC outer wall panel 3 is lifted, the wall 31 is inserted between the limiting protrusions 11 of the four positioning plates 1, the frame 32 abuts against the surface of the limiting protrusions 11, and then the ACC outer wall panel 3 is fixed to the wall 31. The fixing adopts the commonly used fixing method in the existing technology, such as expansion screw connection.

[0031] Example 2

[0032] like Figures 4-7 As shown, this embodiment provides an auxiliary installation device for ACC exterior wall panels, including a positioning plate 1 and a pre-embedded column 2.

[0033] The positioning plate 1 has a cross-shaped limiting protrusion 11 on its outward side. The extension line of the midpoint of the limiting protrusion 11 extending towards its surface coincides with the extension line of the midpoint of the positioning plate 1 extending towards its surface. The positioning plate 1 has a connecting hole 13 on its surface. The connecting hole 13 is a countersunk hole. Specifically, the limiting protrusion 11 divides the positioning plate 1 into four quadrants 111. There are four connecting holes 13 located in the four quadrants 111 respectively. The positioning plate 1 has four pre-drilled holes 14 located in the four quadrants 111 respectively and close to the middle of the limiting protrusion 11. The vertical projection of the pre-drilled hole 14 coincides with the vertical projection of the surface of the embedded column 2.

[0034] The embedded column 2 is located on the back of the positioning plate 1. The positioning plate 1 can rotate around the axis of the embedded column 2. The positioning plate 1 is limited by a limiting member passing through the pre-drilled hole 14 and screwed into the embedded column 2. Specifically, the middle of the limiting protrusion 11 is provided with a first countersunk hole 112, and the embedded column 2 is provided with a threaded hole 21 on its surface. The positioning plate 1 and the embedded column 2 are connected by a connector 4 passing through the first countersunk hole 112 and screwed into the threaded hole 21. The connector 4 includes a locking part, a connecting part, and a threaded part. The locking part, the connecting part, and the threaded part are connected in sequence. The locking part and the connecting part are located in the first countersunk hole 112. The threaded part has an external thread, and the threaded part is adapted to the threaded hole 21.

[0035] Working principle: Four matrix-set positioning plates 1 are installed on the wall 31, and the horizontal and vertical orientations of the four positioning plates 1 are adjusted. The pre-embedded columns 2 extend into the wall 31, and then the horizontal and vertical orientations of the positioning plates 1 are adjusted. After the positioning plates 1 are adjusted, the connecting parts 4 are tightened first, so that the positioning plates 1 abut against the pre-embedded columns 2 to achieve initial positioning. Then, a drill bit is used to drill through the pre-drilled hole 14, so that the surface of the pre-embedded column 2 is formed with connecting screw holes. Then, screws are inserted through the pre-drilled hole 14 and screwed into the connecting screw holes to limit the positioning of the positioning plates 1. Finally, the connecting hole 13 is locked to the wall 31 with expansion screws. During installation, the ACC outer wall panel 3 is lifted, the wall 31 is inserted between the limiting protrusions 11 of the four positioning plates 1, the frame 32 abuts against the surface of the limiting protrusions 11, and then the ACC outer wall panel 3 is fixed to the wall 31. The fixing adopts the commonly used fixing method in the existing technology, such as expansion screw connection.
