A prefabricated wall and its assembly method

Abstract

This invention discloses a prefabricated wall and its assembly method, specifically relating to the field of prefabricated walls. The wall includes a main wall panel with multiple sets of impact-resistant protective components arranged in a rectangular array. Each impact-resistant protective component includes a square column body, with an extended end fixed to one end and a rear baffle detachably connected to the other end.

This invention assembles separate impact-resistant protective components on the main wall panel. In the event of scratches or collisions, the adjusting groove corresponding to the square column body slides along a stop protrusion II. The contact between stop protrusion II and stop protrusion I prevents the square column body from retracting. Adjacent impact-resistant protective components simultaneously use stop protrusions I and II to jointly block the impact, thus dissipating the collision stress and forming a chain-like buffer effect. This ensures the versatility of the prefabricated wall system in various application locations and has higher application prospects.

Description

Technical Field

[0001] This invention relates to the field of prefabricated wall technology, and more specifically, to a prefabricated wall and its assembly method. Background Technology

[0002] Prefabricated wall systems are an important component of modern industrialized construction. They involve prefabricating and assembling wall structures in factories for rapid on-site installation, aiming to improve construction efficiency, reduce costs, enhance project quality, and achieve sustainable development. With the rapid development of the construction industry, prefabricated wall systems have gained significant attention due to their high efficiency and environmental friendliness. However, existing prefabricated wall systems still have many shortcomings in terms of material performance, structural layout, and construction techniques, limiting their widespread application.

[0003] With the explosive growth in the number of family cars today, vehicle collisions with walls or other objects are frequent on roads. In response, protective devices are installed in accident-prone locations, while guardrails or water-filled barriers are placed in areas where large devices are impractical. In more spacious areas, protective walls can be installed to reduce the likelihood of personal injury from accidental collisions. However, most existing protective devices are rigid barriers. Both minor scrapes and impacts can damage or deform these devices, requiring complete replacement and causing impact damage to the vehicle. This is especially true for common continuous guardrails, which are prone to collapsing due to minor collisions, resulting in prohibitively high maintenance and replacement costs, significantly increasing operating costs. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the embodiments of the present invention provide a prefabricated wall and an assembly method. The technical problem to be solved by the present invention is: how to prepare a non-rigid barrier protective wall to reduce the cost of use and protect the personal safety of drivers.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated wall panel, comprising a wall panel main board, wherein multiple sets of impact-resistant protective components are arranged in a rectangular array on the wall panel main board;

[0006] The wall panel includes a main body plate. A loading rail is fixedly provided on one side of the main body plate, and an assembly groove is provided on the other side of the main body plate. Limiting grooves are provided at the alignment points of the main body plate and the impact protection component. The limiting grooves are evenly arranged in a rectangular array in the lower middle part of the main body plate.

[0007] The impact-resistant protective component includes a square column body, one end of which is fixedly provided with an extended end head, and the other end of which is detachably connected with a rear baffle. Adjustment grooves are provided at the center of all four sides of the square column body and the extended end head, and multiple stop protrusions I are equidistantly arranged on the inner wall of the adjustment grooves.

[0008] In a preferred embodiment, the loading cams of two adjacent main plates are movably inserted into the assembly slots, and a mounting base plate is fixedly provided at the bottom of the main plate. A plurality of mounting holes are evenly provided on the mounting base plate, and bolts are used to fix the wall main plate mounting position to the ground through the mounting holes.

[0009] The limiting groove penetrates the main body plate. The size of the limiting groove is equivalent to the size of the square column main body. The inner walls of the four sides of the limiting groove are provided with stop protrusions II. The stop protrusions II are longitudinally provided with replacement holes. The stop protrusions II and the inner walls of the limiting groove are fixed by bolts through the replacement holes.

[0010] Both the stop bump I and the stop bump II have chamfered edges for smoothness.

[0011] In a preferred embodiment, the extended end is configured as a frustum conical shape, the square column body and the extended end are integrally injection molded, and the geometry formed by the square column body and the extended end is hollow.

[0012] Multiple protective protrusions are uniformly fixed on the surface of the extended end away from the main body of the square column;

[0013] The main body of the square column, the extended end, and the rear baffle are all injection molded from high-density polyethylene, and the protective protrusions are made of high-density sponge or rubber.

[0014] In a preferred embodiment, an identification sticker is provided on the outer wall of the square column body. The color of the identification sticker is set to a color with high contrast to the color of the square column body, and the identification sticker is set as a partition sticker with color saturation gradient.

[0015] In a preferred embodiment, the adjusting slide is aligned with the stop protrusion II, and the adjusting slide is slidably connected to the stop protrusion II. The height of the stop protrusion I is set to 1 / 3 of the height of the stop protrusion II.

[0016] The shape of the adjusting groove is set to match the square column body to the extended end in the shape of a "√".

[0017] In a preferred embodiment, a fixing bolt is provided between the rear baffle and the square column body, and a fixing hole is provided at the connection between the rear baffle and the fixing bolt;

[0018] A traction belt is provided between the rear baffles of the laterally adjacent anti-impact protective components, and a fixing rivet is fixed between the end of the traction belt and the rear baffle.

[0019] In a preferred embodiment, the size of the back baffle is equivalent to the size of the end of the extension head away from the main body of the square column. After multiple sets of anti-impact protective components are assembled on the main body of the wall, multiple sets of extension heads and the back baffle form a continuous wall parallel to the main body on both sides of the main body.

[0020] The length of the main body of the square column is greater than the length of the limiting through groove, that is, when the impact protection component is assembled on the main body of the wall, the extended end forms the outer facade of the main body plate.

[0021] The present invention also includes a method for assembling a prefabricated wall, the specific assembly steps of which are as follows:

[0022] S1: Transport the wall panel to the installation location, use bolts to fix the single main panel to the ground at the installation location through the mounting holes, and then use the loading cam rail and assembly slot to assemble multiple wall panels into a continuous wall in sequence, and use bolts to fix the subsequent wall panels through the mounting holes.

[0023] S2: Insert the square column body of each impact protection component into the limiting through groove in sequence, wherein the extended end is installed on the side of the main body plate closest to the road;

[0024] S3: Connect the rear baffle connected by the traction belt to the main body of the square column one by one, and use fixing bolts to fix the baffle to the main body of the square column through the fixing hole position;

[0025] S4: Push the rear panel and check if there is a different colored sticker on the side of the main panel away from the road to determine if the impact protection component has been pushed into place and complete the assembly;

[0026] S5: Regularly inspect the condition of the assembled wall. If the anti-impact protective parts are damaged, replace them separately. If there is a different colored label sticker on the back of the main panel, push the back panel to complete the reset.

[0027] The technical effects and advantages of this invention are as follows:

[0028] 1. This invention is configured to install a split-type anti-impact protective component on the main wall panel. In the event of a scratch or collision, the anti-impact protective component retracts along the direction of the limiting groove, causing the adjusting slide corresponding to the square column body to slide along the stop protrusion II. The contact between the stop protrusion II and the stop protrusion I blocks the retraction of the square column body. After the stop protrusion I at this position smoothly passes the stop protrusion II position, the next stop protrusion I continues to contact the stop protrusion II to form an intermittent blocking force. The adjacent anti-impact protective components work synchronously with the stop protrusion I and stop protrusion II to block the impact stress, thus completing the stress relief effect and forming a chain protection. This not only provides flexible blocking but also has a chain buffering effect, ensuring the versatility of the prefabricated wall system in various application locations and having a higher application prospect.

[0029] 2. This invention involves inspecting the back of the wall panel. If a label with a significantly different color from the rear baffle is found, the rear baffle at that point is pushed to reset the impact protection component. The adjacent impact protection components are then checked to see if they also have exposed labels. If so, they are reset as well. It is ensured that no labels are exposed by checking the back of the wall panel. The reset impact protection component can still continue to provide protection. If damage occurs during maintenance, only the stop protrusion II needs to be replaced. This reduces maintenance and replacement costs and lowers the overall cost of use. Attached Figure Description

[0042] 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.

[0043] Example 1:

[0044] This invention provides, for example Figure 1-2 The prefabricated wall shown includes a wall panel 10. Multiple sets of impact-resistant protective components 20 are arranged in a rectangular array on the wall panel 10. After the multiple sets of impact-resistant protective components 20 are sequentially assembled onto the wall panel 10, relatively separated exterior facades are formed on both sides of the lower part of the wall panel 10. A "split wall" (e.g., a section protruding a certain size) is formed near the roadway where vehicles travel. Figure 1 (Viewing conditions), only the lower part of the wall main board 10 (30cm-150cm height) is equipped with impact protection components 20. This can protect vehicles of normal height without having to install impact protection components 20 on the entire height of the wall main board 10. On the one hand, this can reduce costs, and on the other hand, the wall main board 10 at an appropriate height can achieve the same visual obstruction effect as traditional walls / panels.

[0045] like Figure 3-4 As shown, the wall panel 10 includes a main body plate 101. A loading rail 102 is fixedly provided on one side of the main body plate 101, and an assembly groove 103 is provided on the other side of the main body plate 101. Limiting grooves 104 are provided at the alignment points of the main body plate 101 and the anti-impact protective component 20. The limiting grooves 104 are evenly arranged in a rectangular array in the lower part of the main body plate 101. The loading rails 102 of two adjacent main bodies 101 are movably inserted into the assembly grooves 103. After the adjacent wall panels 10 are assembled, bolts can be used to fix them again to ensure the installation stability of the connection.

[0046] Specifically, a mounting base plate 105 is fixedly provided at the bottom of the main body plate 101. Multiple mounting holes are evenly provided on the mounting base plate 105. Bolts are used to fix the wall main body plate 10 to the ground at the mounting position through the mounting holes. The mounting base plate 105 added at the bottom of the main body plate 101 is one state. In addition, a precast concrete base or a water-filled base similar to a water-filled barrier is added at the bottom of the main body plate 101, which can achieve the same effect of supporting the main body plate 101.

[0047] Furthermore, the limiting groove 104 penetrates the main body plate 101. The size of the limiting groove 104 is comparable to that of the square column main body 201. The inner walls of the limiting groove 104 are provided with stop protrusions II 106 on all four sides. The edges of the stop protrusions I 207 and II 106 are chamfered and smooth. The stop protrusions I 207 and II 106 are made of high-density polyethylene material. Due to its high surface hardness and rigidity, it ensures the buffering effect of the impact protection component 20 when passing through the limiting groove 104. When the impact protection component 20 passes through the limiting groove 104, it is restricted by the position of the stop protrusions II 106 and I 207. The side of the hollow square column main body 201 forms a slight arc-shaped deformation, which avoids jamming and prevents the impact protection component 20 from being unable to move. It also avoids cracking or direct breakage when the impact force is greater than the fracture strength of the material itself, thus ensuring its service life.

[0048] like Figure 6 As shown, the impact protection component 20 includes a square column body 201, an extended end head 202 is fixedly provided at one end of the square column body 201, a rear baffle 203 is detachably connected to the other end of the square column body 201, and a plurality of protective protrusions 204 are uniformly fixed on the surface of the extended end head 202 away from the square column body 201.

[0049] like Figure 6-8As shown, adjusting grooves 206 are provided at the center of each of the four sides of the main body 201 and the extended end 202. The shape of the adjusting grooves 206 is set to match the "√" shape of the main body 201 and the extended end 202. Multiple stop protrusions I 207 are evenly distributed on the inner wall of the adjusting grooves 206. The extended end 202 is set in the shape of a frustum. The main body 201 and the extended end 202 are integrally injection molded, and the geometry formed by the main body 201 and the extended end 202 is hollow. The adjusting grooves 206 are aligned with the stop protrusions II 106, and the adjusting grooves 206 and the stop protrusions II 106 slide. The height of the stop protrusion I 207 is set to 1 / 3 of the height of the stop protrusion II 106. The square column body 201, the extension end 202 and the rear baffle 203 are all injection molded from high-density polyethylene, and the protective protrusion 204 is made of high-density sponge or rubber. The extension end 202 is designed to prevent the square column body 201 from moving excessively when it is inserted into the limiting groove 104, so that it can be separated from the limiting groove 104, thereby preventing the vehicle from directly rubbing against the main plate 101. And because the hollow geometry of the square column body 201 and the extension end 202 is relatively less damaging to the vehicle compared to the main plate 101.

[0050] like Figure 2 and 8 As shown in Figure 9, a fixing bolt 209 is provided between the rear baffle 203 and the square column body 201, and a fixing hole 208 is provided at the connection between the rear baffle 203 and the fixing bolt 209; a traction belt 210 is provided between the rear baffles 203 of the laterally adjacent anti-impact protective components 20, and a fixing rivet 211 is fixed between the end of the traction belt 210 and the rear baffle 203.

[0051] The present invention also includes a method for assembling a prefabricated wall, the specific assembly steps of which are as follows:

[0052] S1: Transport the wall panel 10 to the installation location, use bolts to fix the single main panel 101 to the ground of the installation location through the mounting holes, and then use the loading cam 102 to movably connect with the assembly groove 103 to assemble multiple wall panels 10 into a continuous wall, and use bolts to fix the subsequent wall panels 10 through the mounting holes.

[0053] S2: Insert the square column body 201 of each impact protection component 20 into the limiting through groove 104 in sequence, wherein the extension end 202 is installed on the side of the main body plate 101 near the road.

[0054] S3: Connect the rear baffle 203 connected by the traction belt 210 to the square column body 201 one by one, and use the fixing bolts 209 to fix the baffle 203 to the square column body 201 through the fixing holes 208.

[0055] S4: Push the rear baffle 203 and check whether there is a different colored label 205 on the side of the main plate 101 away from the road surface to determine whether the impact protection component 20 has been pushed into place and complete the assembly.

[0056] S5: Regularly inspect the usage of the assembly wall. If the impact protection component 20 is damaged, replace it separately. If a different colored label 205 is prominent on the back of the main plate 101, push the rear baffle 203 to complete the reset.

[0057] After the prefabricated wall assembly is completed, if a scratch or collision occurs due to driver inattention or unexpected driving route, the vehicle will first come into contact with the extended end 202. A slight scratch will cause the car body to first contact the protective protrusion 204 for protection. If the point continues to be subjected to force, the impact protection component 20 will retract along the limiting groove 104. During this process, the square column body 201 is restricted by the limiting groove 104, causing the adjusting slide 206 corresponding to the square column body 201 to slide along the stop protrusion II 106. The contact between the stop protrusion II 106 and the stop protrusion I 207 causes the square column body 201 to retract. The retracted body provides a barrier. If stress continues to be generated, due to the smooth chamfered design of the edges of the stop protrusions I 207 and II 106 and the slight deformation of the square column body 201, the stop protrusion I 207 can still pass smoothly through the stop protrusion II 106 position. The next stop protrusion I 207 continues to abut against the stop protrusion II 106 to form an intermittent barrier force. When the impact force is borne by the impact protection component 20, it retracts in the corresponding limiting groove 104. This method is not a one-time event and will not cause damage to the impact protection component 20 due to a single impact (except for major accident impacts).

[0058] At this time, as the impact protection component 20 retracts, the rear baffle 203 at the end of the impact protection component 20 moves backward synchronously. The traction belt 210 pulls the adjacent impact protection component 20 to move in the same direction. The stop protrusions I 207 and II 106 of the adjacent impact protection component 20 work together to block and relieve the impact stress. Thus, the impact protection components 20 adjacent to the collision point achieve synchronous protection and form a chain protection. Compared with the traditional rigid barrier, it not only provides a flexible barrier (the collision point can move backward and does not maintain the original position), but also has the effect of chain buffering to relieve the stress. This avoids the need for excessive displacement to buffer the excessive force on a single point, which would require thickening the prefabricated wall to adapt. This ensures the versatility of the prefabricated wall in terms of application locations.

[0059] Example 2:

[0060] Based on the prefabricated wall proposed in Embodiment 1, the present invention provides further technical solutions for the wall main board 10 and the impact protection component 20.

[0061] Please see Figure 6 The outer wall of the square column body 201 provided by the present invention is provided with an identification sticker 205. The color of the identification sticker 205 is set to a color with high contrast with the color difference of the square column body 201, and the identification sticker 205 is set as a partition sticker with color saturation gradient.

[0062] Please see Figure 1 and 6 -8. The size of the rear baffle 203 is approximately the same as the size of the end of the extension head 202 furthest from the main body 201. After assembling multiple sets of impact-resistant protective components 20 at the position of the main wall panel 10, multiple sets of extension heads 202 and rear baffle 203 form a continuous wall parallel to the main body panel 101 on both sides of the main body panel 101. This installation is suitable for straight road locations. However, in curved locations (such as the bend in a parking lot ramp), the main body panel 101 can be set as an arc-shaped panel with a certain curvature, and the extension head 202... The position is set parallel to the main body plate 101 in this state, and the position of the rear baffle 203 forms a discontinuous surface (but still a traction belt 210 is set for connection); the length of the square column main body 201 is greater than the length of the limiting through groove 104, that is, when the anti-impact protection component 20 is assembled on the wall main body 10, the extended end 202 forms the outer facade of the main body plate 101, and the stop protrusion II 106 has a replacement hole 107 longitudinally opened, and the stop protrusion II 106 and the inner wall of the limiting through groove 104 are fixed by bolts through the position of the replacement hole 107.

[0063] When conducting regular inspections of prefabricated walls, the maintenance methods can be categorized as follows based on the inspection results:

[0064] 1. When inspecting the assembled wall, check from the back side of the main wall panel 10 (i.e., the side of the protruding rear baffle 203). If a label 205 with a color that is significantly different from the color of the rear baffle 203 is found, push the rear baffle 203 at that point to reset the anti-impact protection component 20. Then check whether the adjacent anti-impact protection components 20 also have a label 205 exposed. Reset them in the same way.

[0065] 2. If the anti-impact protection component 20 is clearly resisted when the rear baffle 203 is pushed to reset the anti-impact protection component 20, then it is sufficient to ensure that no label 205 is exposed on the back side of the wall main board 10. The anti-impact protection component 20 at the reset point can still continue to play a protective role. Even if the collision point is hit again during the inspection interval, if the square column body 201 corresponding to the anti-impact protection component 20 is not completely submerged in the limiting through groove 104, it can continue to play a protective role.

[0066] 3. If the anti-impact protection component 20 has weak or no obvious blocking force when the rear baffle 203 is pushed to reset the anti-impact protection component 20, then the fixing rivet 211 and fixing bolt 209 corresponding to the anti-impact protection component 20 at that point should be removed. After removing the rear baffle 203, the square column body 201 together with the extended end 202 should be pulled out from the limiting through groove 104. The bolts should be removed from the replacement hole 107 position. The damaged or deformed stop protrusion II 106 should be replaced separately with the same component specifications. The anti-impact protection component 20 should be assembled in the reverse order of the installation and disassembly sequence.

[0067] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may change.

[0068] Secondly: The accompanying drawings of the embodiments disclosed in this invention only involve the structures involved in the embodiments disclosed in this invention. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this invention can be combined with each other.

[0069] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

A method for assembling the prefabricated wall structure according to any one of claims 1-3, characterized in that: The specific assembly steps are as follows: S1: Transport the wall main board (10) to the installation location, use bolts to fix the single main board (101) to the ground of the installation location through the mounting holes, and then use the loading cam (102) to connect with the assembly slot (103) to assemble multiple wall main boards (10) into a continuous wall, and use bolts to fix the subsequent wall main boards (10) through the mounting holes; S2: Insert the square column body (201) of each impact protection component (20) into the limiting through groove (104) in sequence, wherein the extension end (202) is installed on the side of the main body plate (101) close to the road; S3: Connect the rear baffle (203) connected by the traction belt (210) to the square column body (201) one by one, and use the fixing bolts (209) to fix the baffle (203) to the square column body (201) through the fixing holes (208); S4: Push the rear panel (203) and determine whether the impact protection component (20) has been pushed into place by observing whether there is a different colored label (205) on the side of the main plate (101) away from the road surface. This completes the assembly. S5: Regularly inspect the use of the assembly wall. If the anti-impact protection component (20) is damaged, replace it separately. If a different colored label (205) is prominent on the back of the main plate (101), push the back baffle (203) to complete the reset.
