Description

Technical Field

[0001] The present invention relates to the technical field of building wall construction, and more particularly to a prefabricated standardized combined exterior wall and an installation process thereof. Background Art

[0002] Walls mainly include load-bearing walls and non-load-bearing walls, which mainly play the role of enclosing and dividing space. The walls of load-bearing structure buildings combine load-bearing and enclosing functions. The function of the walls of skeleton structure system buildings is to enclose and divide space. The walls must have sufficient strength and stability, and have the ability to keep warm, insulate, soundproof, fireproof and waterproof.

[0003] With the continuous advancement of building industrialization, the design of prefabricated wall panels continues to evolve to meet the practical requirements of installation convenience, stability, and safety. For example, Publication No. CN207348257U discloses a modular exterior wall for prefabricated buildings. This design utilizes modular prefabricated wall panels to reduce on-site construction work and minimize the environmental impacts associated with on-site construction, thereby accelerating on-site construction progress.

[0004] However, in practice, it cannot be ignored that, usually in the process of assembling the exterior wall, it is necessary to install and connect the various assemblies. During the assembly process, problems such as the assembly tipping over and inaccurate positioning may occur, affecting the stability and tightness of the installation of each assembly. In addition, the installation between the assemblies usually adopts the method of setting steel parts and bolts on the surface for connection. There will be gaps in the connection between the walls, which affects the tightness of the installation between the assemblies. Therefore, a new prefabricated standardized composite exterior wall design is in urgent need of development. Summary of the Invention

[0037] The present invention will be further described below with reference to the embodiments.

[0038] Example

[0039] Combine Figure 1-Figure 5 , a prefabricated standardized composite exterior wall of this embodiment includes: an assembly 1, the assembly 1 includes an exterior wall panel 11, a filling material 12 and an I-shaped steel beam 13 arranged in sequence and tightly spliced; a retaining block 4 is also provided on one side of the I-shaped steel beam 13, the retaining block 4 is fixedly connected to the middle cavity of the I-shaped steel beam 13, and the retaining block 4 is fixed to the ground. The filling material 12 specifically adopts a thermal insulation material. In this embodiment, an I-shaped steel beam 13 is adopted, and the middle part of the filling material 12 and the retaining block 4 corresponds to the inner cavity of the I-shaped steel beam 13, so that the top and bottom surfaces of the assembly 1 as a whole are still flush, which is convenient for installation operation. And through the setting of the retaining block 4, the I-shaped steel beam 13 is initially supported, further ensuring the stability of the I-shaped steel beam 13 during installation.

[0040] In this embodiment, support units 2 are provided on the exterior of exterior wall panels 11. Support units 2 have downward-applying ends for applying pressure from the top of assembly 1, keeping it tightly assembled. Furthermore, snap-fit units 3 are provided within assembly 1 to horizontally lock and connect exterior wall panels 11, filler material 12, and I-shaped steel beam 13. In other words, support units 2 and snap-fit units 3 work together to secure the exterior wall panels 11 and filler material 12, respectively, vertically and horizontally, enhancing the stability of the overall structure.

[0041] As an optional embodiment of the support unit 2, combined with Figure 1 and Figure 2 As shown, the support unit 2 includes a placement plate 21 connected to the exterior wall panel 11. The four corners of the bottom of the placement plate 21 are fixedly connected to pillars, the bottom surfaces of which are flush with the bottom surface of the assembly 1 to support and secure the placement plate 21. Two movable frames 22 are provided at the top and ends of the placement plate 21. A rotating plate 23 is rotatably connected to the inner cavity of the movable frame 22. The top of the rotating plate 23 at the outer end is connected to the electric telescopic rod 1 24, and the top of the rotating plate 23 at the inner end is connected to the block 25. A round rod 26 is connected to the top of the block 25. A sliding sleeve 27 is slidably connected to the surface of the round rod 26. Two connecting rods 28 are symmetrically provided on either side of the surface of the sliding sleeve 27. The two connecting rods 28 are rotatably connected to the first rotating frame 29 and the second rotating frame 210, respectively. More precisely, a U-shaped rotating frame is provided between the connecting rods 28 on both sides. The U-shaped rotating frame 1 29 is located on the lower side, and the U-shaped rotating frame 210 is located on the upper side. Both can rotate relative to the sliding sleeve 27. The middle portion of the lower rotating frame 1 (29) is connected to the output end of the electric telescopic rod 1 (24). The top of the round rod 26 is connected to a connecting block 211, the surface of which is rotatably connected to a support plate 1 (212). The bottom of the support plate 1 (212) contacts the I-shaped steel beam 13. One end of the support plate 1 (212) is connected to a connecting frame 213, the inner cavity of which is rotatably connected to a connecting rod 214. The bottom end of the connecting rod 214 is connected to the middle portion of the rotating frame 2 (210). More optimally, a spring 215 is sleeved on the surface of the round rod 26, the ends of which are respectively connected to the sliding sleeve 27 and the connecting block 211. The provision of the spring 215 serves to buffer and limit the movement of the sliding sleeve 27, to a certain extent preventing excessive movement of the sliding sleeve 27. In order to further improve the fastening and supporting effect of the support unit 2 on the assembly 1, a support plate 216 is fixedly connected to the side of the block 25 close to the exterior wall panel 11, and anti-slip grooves are provided on the opposite wall surfaces of the support plate 216 and the exterior wall panel 11; the bottom of the support plate 1 212 is also provided with anti-slip grooves, thereby increasing the contact friction and improving the supporting force.

[0042] As an optional embodiment of the buckle unit 3, combined with Figure 3 、 Figure 4 and Figure 5As shown, the buckle unit 3 includes a fixing rod 31 fixedly connected to the I-shaped steel beam 13, and the filling material 12 and the I-shaped steel beam 13 are correspondingly provided with a through hole 311 for the fixing rod 31 to pass through; Figure 3 The fixed rod 31 and the through hole 311 are symmetrically arranged at the four corners. The inner cavity of the fixed rod 31 is provided with an electric telescopic rod 32, the output end of which is connected to a transmission rod 33. A groove 34 is provided inside the fixed rod 31, and the transmission rod 33 is located within the groove 34. The inner cavity of the groove 34 is rotatably connected to two support rods 35, which are symmetrically distributed up and down. The surface of the support rod 35 is connected to a V-shaped transmission block 36. The two sides of the transmission block 36 are connected to a positioning block 37 and a mounting block 38, respectively. The surface of the positioning block 37 is connected to the transmission rod 33. A mounting ring 39 is also fixed in the through hole 311 of the exterior wall panel 11. The surface of the mounting block 38 is adapted to fit with the mounting ring 39. At this time, the telescopic drive of the electric telescopic rod 32 can translate the transmission rod 33, thereby driving the rotation of the transmission block 36, causing the mounting block 38 to deflect. When it flips and fits into the mounting ring 39, the connection between the assemblies 1 is achieved.

[0043] Combine Figure 5 As shown, to ensure the stable positioning of the transmission rod 33 and the positioning block 37, an optimized solution is as follows: the transmission rod 33 is provided with a placement groove adapted for the positioning block 37, and the positioning block 37 is inserted into the placement groove. At this time, as the transmission rod 33 is extended or retracted, the transmission block 36 rotates, causing the mounting block 38 to lock and release with the mounting ring 39. Similarly, in a further implementation, the surface of the second electric telescopic rod 32 is further provided with a fixing block 310. The fixing rod 31 is provided with a corresponding mounting position, i.e., a mounting positioning groove, which cooperates with the fixing block 310. This secures the second electric telescopic rod 32 and improves the stability of the second electric telescopic rod 32 during operation.

[0044] The installation process of the above-mentioned prefabricated standardized composite exterior wall of this embodiment is to place the exterior wall panel 11, filling material 12, I-shaped steel beam 13 and blocking block 4 in the assembly 1 in sequence, start the support unit 2, and use its downward pressure end to apply pressure from the top of the assembly 1 to keep the assembly 1 in a tight state; then use the snap unit 3 to lock and engage the exterior wall panel 11, filling material 12, and I-shaped steel beam 13 axially to achieve overall stable installation.

[0045] Specifically, the following processes are involved:

[0046] Step 1: The user places the I-shaped steel beam 13 on one side of the blocking block 4, places the filling material 12 in the inner cavity of the I-shaped steel beam 13, and places the exterior wall panel 11 on one side of the filling material 12; the fixing rod 31 on the I-shaped steel beam 13 passes through the through hole 311 in the filling material 12 and penetrates the mounting ring 39 on the exterior wall panel 11;

[0047] Step 2: The user turns on the electric telescopic rod 1 24. The output end of the electric telescopic rod 1 24 pushes the block 25 to move the rear movable frame 22 as the axis through the cooperation of the sliding sleeve 27 and the round rod 26, and drives the sliding sleeve 27 to slide upward. The sliding sleeve 27 drives the rotating frame 210 to rotate upward with the connecting rod 28 as the axis. The sliding sleeve 27 pushes the support plate 1 212 downward through the cooperation of the connecting rod 214, the connecting frame 213 and the connecting block 211, thereby making the support plate 216 and the support plate 1 212 respectively against the exterior wall panel 11 and the I-shaped steel beam 13, thereby completing the support of the exterior wall panel 11, the filling material 12 and the I-shaped steel beam 13 and keeping them in a tight state. The electric telescopic rod 1 24 can be closed.

[0048] Step 3: Turn on the electric telescopic rod 2 32. The output end of the electric telescopic rod 2 32 pushes the transmission rod 33 to move forward. The transmission rod 33 pulls the transmission block 36 to rotate with the support rod 35 as the axis through the cooperation of the placement slot, so that the two positioning blocks 37 are in a parallel state. At the same time, the two mounting blocks 38 are respectively embedded in the mounting rings 39 and fixed. The wall surface close to the mounting ring 39 and the fixing rod 31 is provided with an inwardly extending abutment plate. When the mounting block 38 is embedded in the mounting ring 39, it is limited and abutted by the abutment plate; thereby completing the purpose of installing the exterior wall panel 11, the filling material 12 and the I-shaped steel beam 13. At this time, the electric telescopic rod 2 32 can be closed.

[0049] The composite exterior wall of this embodiment applies pressure and tightens the top and side areas of the combination of the exterior wall panel 11, the filling material 12 and the I-shaped steel beam 13 through the support unit 2 to keep it basically stable, and then further locks the three together from the inside in the horizontal direction through the snap unit 3, thereby achieving further reinforcement. The stability and tightness of the overall structure are guaranteed, and the operation is very convenient, the labor intensity is low, and it is suitable for practical construction environments.

[0050] The above is a schematic description of the present invention and its embodiments. This description is not restrictive and is only one embodiment of the present invention. Therefore, if a person skilled in the art is inspired by this description and, without departing from the purpose of the present invention, designs structures and embodiments similar to this technical solution without creatively designing them, they shall fall within the scope of protection of the present invention.
