Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, specifically to a prefabricated building wall panel. Background Technology

[0002] Prefabricated buildings, with their advantages of short construction cycles, low resource consumption, and minimal on-site pollution, have become an important direction for the development of the construction industry. As the core enclosure component of prefabricated buildings, the installation and positioning accuracy of wall panels directly affects the stability and appearance quality of the overall structure. Currently, the installation of prefabricated building wall panels requires hoisting to determine their position, followed by repeated manual adjustments of adjacent wall panels to ensure seam alignment. This process is highly dependent on the experience of the operators and is time-consuming. If the positioning accuracy is not up to standard, it can create hidden dangers for the subsequent alignment of adjacent wall panel sections, increasing the overall installation difficulty and ultimately adversely affecting the construction progress and structural safety. Summary of the Invention

[0003] The technical problem to be solved by this utility model is how to improve the installation accuracy when installing prefabricated building wall panels.

[0004] The technical solution adopted by this utility model is: a prefabricated building wall panel, including a wall body, with a first positioning part and a second positioning part respectively provided at both ends of the wall body. The first positioning part includes a first trapezoidal positioning protrusion and a first trapezoidal positioning groove, and the second positioning part includes a second trapezoidal positioning protrusion and a second trapezoidal positioning groove. The first trapezoidal positioning protrusion cooperates with the second trapezoidal positioning groove of the adjacent wall panel, and the second trapezoidal positioning protrusion cooperates with the first trapezoidal positioning groove of the adjacent wall panel. The first trapezoidal positioning protrusion is provided with a first positioning protrusion and a first positioning groove, and the second trapezoidal positioning protrusion is provided with a second positioning protrusion and a second positioning groove. The first positioning protrusion cooperates with the second positioning groove of the adjacent wall panel, and the second positioning protrusion cooperates with the first positioning groove of the adjacent wall panel.

[0005] The above structure has the following beneficial effects:

[0006] By setting a main positioning structure that combines trapezoidal positioning protrusions and trapezoidal positioning grooves at both ends of the wall body, and cooperating with auxiliary positioning structures of the first positioning protrusion and the second positioning groove, and the second positioning protrusion and the first positioning groove, multiple positioning is formed. Through the main positioning structure and the auxiliary positioning structure, the relative displacement of adjacent wall panels can be restricted from multiple directions, so as to achieve precise splicing of wall panels, solve the problems of low splicing accuracy and poor stability of traditional single positioning structure, and improve the overall structural reliability of prefabricated buildings.

[0007] Preferably, the top and bottom surfaces of the first trapezoidal positioning protrusion and the second trapezoidal positioning protrusion are flush with the top and bottom surfaces of the wall body, respectively.

[0008] By ensuring that the top and bottom surfaces of the trapezoidal positioning protrusions are flush with the top and bottom surfaces of the wall body, it is ensured that the overall top and bottom surfaces remain continuous and flat after adjacent wall panels are spliced, avoiding steps or height differences, and also facilitating subsequent construction.

[0009] Preferably, one side of the first trapezoidal positioning protrusion is flush with one side of the wall body, and one side of the second trapezoidal positioning protrusion is flush with the other side of the wall body. The angle between the inclined surfaces of the first trapezoidal positioning protrusion and the second trapezoidal positioning protrusion and the end face of the wall body they are located is an obtuse angle.

[0010] By aligning one side of the trapezoidal positioning protrusion with the side of the wall body, the appearance quality of the wall is further improved by ensuring that no protrusions or depressions appear on the side after the adjacent wall panels are spliced. Furthermore, by setting the angle between the inclined surface of the trapezoidal positioning protrusion and the end face of the wall body it is located to an obtuse angle, a guiding function is provided for the splicing, making it easy for the trapezoidal positioning protrusion to be smoothly embedded into the trapezoidal positioning groove. At the same time, it increases the contact area of ​​the splicing surface and improves the stability of the connection.

[0011] Preferably, there are two of each of the first positioning groove and the second positioning protrusion. The first positioning groove is respectively located on the end face of the wall body where the first trapezoidal positioning protrusion is located, and on the end face of the first trapezoidal positioning protrusion away from the wall body. The second positioning protrusion is respectively located on the end face of the wall body where the second trapezoidal positioning protrusion is located, and on the end face of the second positioning protrusion away from the wall body.

[0012] By setting two first positioning grooves and two second positioning protrusions at different positions, and making the first positioning grooves at different positions engage with the second positioning protrusions on the adjacent wall panels, the potential shaking of the prefabricated building wall panels during the splicing process, which could cause changes in position, is further prevented. Through coordinated cooperation with the main positioning structure, the splicing stability between adjacent wall panels is significantly improved.

[0013] Preferably, both the first trapezoidal positioning protrusion and the second trapezoidal positioning protrusion are provided with a first grouting cavity, and the two ends of the wall body are provided with a second grouting cavity, and the first grouting cavity and the second grouting cavity are connected.

[0014] By setting up a first grouting cavity and a second grouting cavity, and connecting the first grouting cavity and the second grouting cavity, the grouting material can fill the internal space of the entire positioning structure under pressure or gravity, forming a continuous solidified connection. This method of cavity connection and overall grouting solves the problem of insufficient connection strength caused by mechanical interlocking in traditional splicing, firmly combining adjacent wall panels into one, and improving the overall load-bearing capacity and deformation resistance of the wall.

[0015] Preferably, the top surface of the wall body is provided with a first grouting hole that communicates with the second grouting cavity.

[0016] By setting a first grouting hole on the top surface of the wall body that communicates with the second grouting cavity, a convenient entry point is provided for the grouting operation. Compared with side or bottom grouting, top grouting is more in line with construction habits and makes it easier for operators to observe the grouting progress. When the grout overflows, it can be judged that the cavity has been filled, reducing the problem of insufficient or excessive grouting and improving construction efficiency and grouting quality.

[0017] Preferably, the bottom of the first grouting cavity and the second grouting cavity are provided with a guide slope.

[0018] By setting guide ramps at the bottom of the first and second grouting chambers, the grouting material can be guided to flow naturally along the ramps, avoiding grout stagnation or cavity problems caused by the flat bottom of the chambers. This ensures that the grouting material can fully fill every corner of the grouting chamber, especially the gap between the positioning protrusions and the grooves. After curing, it forms a seamless connection structure, improving the sealing and strength of the splicing parts.

[0019] Preferably, the angle between the guide slope and the horizontal direction is an acute angle.

[0020] By setting the angle between the guide slope and the horizontal direction to an acute angle, the flow path and speed of the grout are optimized. The acute angle design ensures that the grout can flow smoothly under the action of gravity, avoiding slow flow due to too small an angle, and also prevents air bubbles from being generated due to too fast a flow rate due to too large an angle. This ensures that the grouting material is filled evenly and densely, further improving the reliability of the connection after curing.

[0021] Preferably, the bottom side of the wall body is provided with a plurality of second grouting holes arranged at intervals, and the bottom surface of the wall body is provided with a plurality of interlocking holes arranged at intervals, wherein the second grouting holes and the interlocking holes are connected.

[0022] By setting multiple second grouting holes on the bottom side of the wall body and multiple interlocking holes on the bottom surface of the wall body, and making the second grouting holes and interlocking holes connected, after the interlocking holes and steel bars cooperate to position the prefabricated building wall panel, grout is injected into the second grouting holes to fill the gap between the steel bars and the hole wall and after curing, the wall panel is firmly riveted to the building foundation, effectively limiting the vertical displacement and horizontal sway of the wall panel.

[0023] Preferably, the bottom of the first positioning protrusion, the top of the second positioning protrusion, the top of the first positioning groove, and the bottom of the second positioning groove are all provided with rounded corners.

[0024] The rounded corners at the bottom of the first positioning protrusion, the top of the second positioning protrusion, the bottom of the first positioning groove, and the top of the second positioning groove can prevent the edges of the protrusion or groove from cracking or being damaged during the splicing process. At the same time, the rounded corner design reduces the frictional resistance during splicing, allowing the protrusion to be inserted into the groove more smoothly and reducing the difficulty of installation.

[0035] Example

[0036] The following description, in conjunction with a specific embodiment, further illustrates the following. Referring to Figure 1, this embodiment is a prefabricated building wall panel, including a wall body 10. A first positioning portion and a second positioning portion are provided at both ends of the wall body 10. The first positioning portion includes a first trapezoidal positioning protrusion 21 and a first trapezoidal positioning groove 22. The second positioning portion includes a second positioning protrusion 311 and a second positioning groove 312. The top and bottom surfaces of the first trapezoidal positioning protrusion 21 and the second trapezoidal positioning protrusion 31 are flush with the top and bottom surfaces of the wall body 10, respectively. Furthermore, the inclined surfaces of the first trapezoidal positioning protrusion 21 and the second trapezoidal positioning protrusion 31 form a blunt angle with the end face of the wall body 10 where the positioning protrusion is located. The first trapezoidal positioning protrusion 21 of the prefabricated building wall panel to be spliced ​​and the second trapezoidal positioning groove 32 of the already installed prefabricated building wall panel are in clearance fit to facilitate the reservation of filling space for subsequent grouting. When two adjacent prefabricated building wall panels need to be spliced, the first trapezoidal positioning protrusion 21 is embedded into the second trapezoidal positioning groove 32 of the adjacent prefabricated building wall panel to complete the splicing of the two prefabricated building wall panels. The first trapezoidal positioning protrusion 21 of the prefabricated building wall panel is provided with a first positioning protrusion 211 and a first positioning groove 212, while the second trapezoidal positioning protrusion 31 of the prefabricated building wall panel is provided with a second positioning groove 212. The first positioning protrusion 211 and the second positioning protrusion 311 are both rectangular blocks, and the first positioning groove 212 and the second positioning groove 312 are both rectangular slots. The bottom of the first positioning protrusion 211, the top of the second positioning protrusion 311, the top of the first positioning groove 212, and the bottom of the second groove are all rounded. The first positioning protrusion 211 mates with the second positioning groove 312 on the adjacent prefabricated building wall, and the second positioning protrusion 311 mates with the first positioning groove 212 on the adjacent prefabricated building wall. The first positioning protrusion 211 and the second positioning groove 312 are both rectangular slots. The protrusion 311 and the first positioning groove 212 are both transition fits; in addition, in order to further enhance the connection stability between adjacent walls and ensure that the walls will not shift, there are two of each of the first positioning groove 212 and the second positioning protrusion 311. The first positioning groove 212 is respectively set on the end face of the wall body 10 where the first trapezoidal positioning protrusion 21 is provided, and on the end face of the first trapezoidal positioning protrusion 21 away from the wall body 10. The two second positioning protrusions 311 are respectively set on the end face of the wall body 10 where the second trapezoidal positioning protrusion 31 is provided, and on the end face of the second positioning protrusion 311 away from the wall body 10.A first grouting cavity 40 is provided inside both the first trapezoidal positioning protrusion 21 and the second trapezoidal positioning protrusion 31. The first grouting cavity 40 is a rectangular cavity. A second grouting cavity 50 is provided inside both ends of the wall body 10. The second grouting cavity 50 is also a rectangular cavity, and the first grouting cavity 40 and the second grouting cavity 50 are connected to each other. A first grouting hole 80 is provided on the top surface of the wall body 10, and the first grouting hole 80 is connected to the second grouting cavity 50. A guide slope 60 is provided at the bottom of the first grouting cavity 40 and the second grouting cavity 50. The guide slope 60 forms an acute angle with the horizontal direction, so that the cement injected from the first grouting hole 80 can flow along the guide slope 60 to the first grouting cavity 40. The wall body 10, the trapezoidal positioning protrusion, the first positioning protrusion 211, the second positioning protrusion 311, the first positioning groove 212, and the second positioning groove 312 are integrally cast concrete.

[0037] Multiple second grouting holes 90 are provided at intervals on the bottom side of the wall body 10, and multiple interlocking holes 11 are provided at intervals on the bottom surface of the wall body 10. The second grouting holes 90 and the interlocking holes 11 are connected. In this embodiment, nine second grouting holes 90 and nine interlocking holes 11 are provided respectively. When the interlocking hole 11 is matched with the protruding steel bar at the placement position, cement can be injected into the second grouting hole 90 and fixed to the prefabricated building wall.

[0038] In addition, a lifting groove 70 is provided on the top surface of the wall panel body. The lifting groove 70 is a rectangular groove, and a lifting rod 71 is provided in the lifting groove 70. The two ends of the lifting rod 71 are fixed in the wall body 10, which facilitates the lifting of the prefabricated building wall during installation and transportation. When the prefabricated building wall panel is installed in the preset position and the hook is removed, cement will be filled into the lifting groove 70.

[0039] Working principle:

[0040] When installing prefabricated building wall panels, the lifting rod 71 fixed in the lifting groove 70 set on the wall panel body is first connected to the hook of the external lifting equipment. Through the lifting and moving action of the lifting equipment, the prefabricated building wall panel is transferred to the preset installation position. After being moved to the installation position, the prefabricated building wall panel can be spliced ​​with the pre-set column or another pre-installed prefabricated building wall panel.

[0041] When two adjacent wall panels need to be spliced, the first trapezoidal positioning protrusion 21 of the prefabricated building wall panel to be spliced ​​is aligned with the second trapezoidal positioning groove 32 of the other prefabricated building wall panel that has been installed in advance. Then, it is moved slowly so that the two fit together, and the prefabricated building wall panel to be spliced ​​moves vertically along the splicing surface. As the prefabricated building wall panel to be spliced ​​continues to move, the first positioning protrusion 211 of the prefabricated building wall panel to be spliced ​​gradually embeds into the second positioning groove 312 of the prefabricated building wall panel that has been installed. Similarly, the second positioning protrusion 311 also gradually embeds into the first positioning groove 212, further restricting horizontal offset and rotation, and realizing the precise splicing and positioning of the prefabricated building wall panel.

[0042] After the splicing is completed, cement is injected into the first grouting hole 80 on the top surface of the prefabricated building wall panel. After the cement is injected into the second grouting cavity 50, it flows to the bottom of the second grouting cavity 50 and then flows along the guide slope 60 to the first grouting cavity 40 until the cement fills the first grouting cavity 40 and the second grouting cavity 50. After the cement cures, the two adjacent prefabricated building wall panels are firmly connected.

[0043] Finally, align the interlocking holes 11 at the bottom of the prefabricated building wall panel with the pre-set reinforcing bars and insert them. Then, inject cement into the second grouting hole 90. After the cement solidifies, the reinforcing bars inserted into the interlocking holes 11 are firmly connected to the wall panel body.
