Description

Technical Field

[0001] The present invention relates to the technical field of assembled walls, and more particularly to an assembled wall and an assembly method. Background Art

[0002] Prefabricated walls are a crucial component of modern building industrialization. Through prefabrication and assembly, wall structures are manufactured in factories and rapidly installed on-site. Their goal is to improve construction efficiency, reduce costs, enhance project quality, and achieve sustainable development. With the rapid development of the construction industry, prefabricated walls have attracted significant attention for their efficiency and environmental friendliness. However, existing prefabricated walls still have numerous shortcomings in terms of material performance, structural layout, and construction techniques, limiting their widespread application.

[0003] Under the premise of the explosive increase in the number of family cars today, vehicles often scrape against walls or collide on social roads. Under this premise, protective devices are installed in some places where accidents are prone to occur. Some places that are not conducive to the installation of large devices are often equipped with isolation guardrails or water barriers, while places with wide areas can be equipped with protective walls to reduce the possibility of personal accidents caused by accidental collisions. However, most of the protective devices in the existing technology are rigid barriers. Whether it is a small scrape or a collision, the protective device will be damaged or deformed, which not only requires overall replacement, but also causes impact damage to the vehicle. In particular, some common continuous guardrails are likely to cause continuous dumping due to small scrapes, and the subsequent maintenance and replacement costs are too expensive, which greatly increases the cost of use. Summary of the Invention

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

[0005] To achieve the above-mentioned object, the present invention provides the following technical solutions: an assembled wall, comprising a wall main plate, on which a plurality of groups of anti-impact protective members are arranged in a rectangular array; The wall main plate includes a main body plate, one side of which is fixed with a loading cam, and the other side of which is provided with an assembly groove. The main body plate and the anti-impact protection member are both provided with limiting grooves at their corresponding positions, and the limiting grooves are evenly arranged in a rectangular array in the middle and lower part of the main body plate; The anti-impact protective component includes a square column body, one end of the square column body is fixedly provided with an extended end head, the other end of the square column body is detachably connected to a rear baffle, and adjustment grooves are provided at the centers of the four sides of the square column body and the extended end head, and a plurality of stop protrusions I are evenly arranged on the inner wall of the adjustment groove.

[0006] In a preferred embodiment, the loading convex rails of two adjacent main body panels are movably plugged into the assembly grooves, and a mounting base is fixedly provided at the bottom end of the main body panel. A plurality of mounting holes are evenly opened on the mounting base, and bolts are used to fix the wall main board mounting position to the ground through the mounting holes. The limiting groove passes through the main body plate, and the size of the limiting groove is comparable to that of the main body of the square column. The inner walls of the four sides of the limiting groove are provided with stop protrusions II, and the stop protrusions II are longitudinally provided with replacement holes. The stop protrusions II are fixed to the inner wall of the limiting groove by bolts through the replacement holes. The edges of the stop block I and the stop block II are both chamfered and smooth.

[0007] In a preferred embodiment, the extension end is configured to be in the shape of a right truncated cone, the square column body and the extension end are integrally injection-molded, and the geometric body formed by the square column body and the extension end is hollow; The surface of the extended end away from the square column body is evenly fixed with a plurality of protective ridges; The square column body, the extended end and the rear baffle are all made of high-density polyethylene by injection molding, and the protective convex strips are made of high-density sponge or rubber.

[0008] 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 color contrast with the square column body, and the identification sticker is set to a partition sticker with a color saturation gradient.

[0009] In a preferred embodiment, the adjusting chute is aligned with the stop protrusion II, and the adjusting chute 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. The shape of the adjustment slot is set to be a "√" shape that matches the square column body to the extended end.

[0010] 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; A traction belt is provided between the rear baffles where the laterally adjacent anti-impact protection pieces are aligned, and a fixing rivet is fixed between the end of the traction belt and the rear baffle.

[0011] In a preferred embodiment, the size of the rear baffle is comparable 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 members are assembled at the main wall panel, the multiple sets of extension heads and the rear baffles form a continuous wall parallel to the main body panel on both sides. The length of the square column body is greater than the length of the limiting through slot, that is, when the anti-impact protection piece is assembled on the wall main board, the extended end forms the facade of the outwardly convex main board.

[0012] The present invention also includes an assembly method for a matching wall, and the specific assembly steps are as follows: S1: The wall panels are transported to the installation site. A single panel is fixed to the installation site using bolts through the mounting holes. Multiple wall panels are then assembled into a continuous wall by flexibly connecting the mounting rails with the assembly slots. Subsequent wall panels are then fixed using bolts through the mounting holes. S2: inserting the square column body of each impact protection member into the limiting slot in sequence, wherein the extended end is installed on the side of the main body plate close to the road; S3: Align the rear baffles connected by the traction belt with the main body of the square column one by one, and use fixing bolts to complete the fixation of the rear baffles and the main body of the square column through the fixing holes; S4: Push the tailgate and check whether the anti-impact protective element is in place by checking whether a different-colored label is highlighted on the side of the main plate away from the road. This completes the assembly. S5: Regularly inspect the use of the assembly wall. If the anti-impact protection parts are damaged, replace them separately. If there is a different-colored logo sticker on the back of the main plate, push the rear baffle to reset it.

[0013] Technical effects and advantages of the present invention: 1. The present invention is arranged in an assembly mode in which a split anti-impact protective member is installed on a main wall panel. If a scratch or collision occurs, the anti-impact protective member retracts along the direction of the limit slot, so that the adjustment slide groove corresponding to the square column body slides along the stop protrusion II. The stop protrusion II and the stop protrusion I interfere with each other to block the retraction position of the square column body. After the stop protrusion I at this position passes smoothly through the position of the stop protrusion II, the stop protrusion I at the next position continues to interfere with the stop protrusion II to form an interval-type blocking force. The adjacent anti-impact protective members perform synchronous stop protrusions I and stop protrusions II to jointly block, completing the force unloading effect of the collision stress and forming a chain-type protection. It not only plays a flexible blocking role, but also has the force unloading effect of chain-type buffering, ensuring the versatility of the use location of the assembled wall and having a higher application prospect. 2. The present invention checks from the back side of the wall main board. If an identification sticker of a color obviously different from that of the rear baffle is found, the rear baffle is pushed to complete the reset of the anti-impact protective member at that point, and the adjacent anti-impact protective member is checked to see if there is also an exposed identification sticker. The reset is also completed. It is ensured that no identification sticker is exposed through the back side of the wall main board. After the reset, the anti-impact protective member at that point can still continue to play a protective role. If damage occurs during maintenance, only the stop block II needs to be replaced separately. The maintenance and replacement costs are relatively low, which reduces the cost of use.

DETAILED DESCRIPTION

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Example 1: The present invention provides Figure 1-2 The assembled wall shown in the figure includes a wall main plate 10, on which a plurality of groups of anti-impact protective members 20 are arranged in a rectangular array. After the plurality of groups of anti-impact protective members 20 are sequentially assembled on the wall main plate 10, relatively separated facades are formed on both sides of the middle and lower height of the wall main plate 10, and a "split wall" with a certain size of protrusion is formed near the vehicle driving road (such as Figure 1 The anti-impact protective member 20 is only provided at the middle and lower height of the wall main plate 10 (30cm-150cm height). This can provide protection for vehicles of normal height without installing the anti-impact protective member 20 at the entire height of the wall main plate 10. This can reduce costs on the one hand, and on the other hand, the wall main plate 10 of appropriate height can achieve the sight blocking effect of traditional walls / panels. like Figure 3-4 As shown, the wall main board 10 includes a main body panel 101, a loading convex rail 102 is fixedly provided on one side of the main body panel 101, and an assembly groove 103 is provided on the other side of the main body panel 101. The main body panel 101 and the anti-impact protection member 20 are both provided with limited slots 104 at the positions thereof. The limited slots 104 are evenly arranged in a rectangular array in the middle and lower part of the main body panel 101. The loading convex rails 102 and the assembly grooves 103 of two adjacent main body panels 101 are movably plugged into each other, and can be re-fixed with bolts after the adjacent wall main boards 10 are assembled to ensure the installation stability of the connection. Specifically, a mounting base plate 105 is fixed to the bottom of the main body plate 101. A plurality of mounting holes are evenly opened on the mounting base plate 105. Bolts are used to fix the wall main board 10 to the ground through the mounting holes. The mounting base plate 105 added to the bottom of the main body plate 101 is a state. In addition, a precast concrete base or a water-filled base similar to a water horse is added to the bottom of the main body plate 101 to achieve the same supporting effect on the main body plate 101. Furthermore, the limiting groove 104 runs through the main plate 101, and 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 all provided with stop protrusions II 106; the edges of the stop protrusions I 207 and the stop protrusions II 106 are both chamfered and smooth. Among them, the stop protrusions I 207 and the stop protrusions II 106 are both made of high-density polyethylene material. Their surface hardness and rigidity have strong mechanical strength, which ensures the buffering effect of the anti-impact protection member 20 passing through the limiting groove 104. When the anti-impact protection member 20 passes through the limiting groove 104, it is restricted by the position of the stop protrusions II 106 and the stop protrusions I 207. The side surface of the square column main body 201 set in the hollow shell forms a slight deformation of the arc surface, which avoids the occurrence of jamming and the inability to move the anti-impact protection member 20, and avoids cracks or direct fractures caused by the impact force being greater than the breaking strength of the material itself, thereby ensuring its service life. like Figure 6 As shown, the impact protection member 20 includes a square column body 201, an extension end 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 ridges 204 are evenly fixed on the surface of the extension end 202 away from the square column body 201; like Figure 6-8 As shown, an adjustment slot 206 is provided at the center of each of the four sides of the square column body 201 and the extended end head 202. The shape of the adjustment slot 206 is set to match the "√" shape of the square column body 201 to the extended end head 202. A plurality of stop protrusions I 207 are evenly distributed on the inner wall of the adjustment slot 206. The extended end head 202 is set in a right frustum shape. The square column body 201 and the extended end head 202 are integrally injection molded, and the geometric body formed by the square column body 201 and the extended end head 202 is hollow. The adjustment slot 206 is aligned with the stop protrusion II 106, and the adjustment slot 206 slides with the stop protrusion II 106. 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 extended end 202 and the tailgate 203 are all injection-molded from high-density polyethylene, and the protective ridges 204 are made of high-density sponge or rubber; the provision of the extended end 202 can prevent the square column body 201 from excessive movement when it is immersed in the limiting groove 104, causing it to disengage from the limiting groove 104, thereby preventing the vehicle from directly colliding with the main plate 101. Precisely because the square column body 201 and the extended end 202 are hollow in geometry compared to the main plate 101, the degree of damage to the vehicle is less; like Figure 2 and 8As shown in FIG. 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 aligned with the laterally adjacent anti-impact protective members 20, and a fixing rivet 211 is fixed between the end of the traction belt 210 and the rear baffle 203; The present invention also includes an assembly method for a matching wall, and the specific assembly steps are as follows: S1: The wall main panels 10 are transported to the installation site, and a single main panel 101 is fixed to the installation site ground using bolts through the installation holes. Subsequently, multiple wall main panels 10 are assembled into a continuous wall by movably plugging the loading protruding rails 102 into the assembly grooves 103, and subsequent wall main panels 10 are fixed using bolts through the installation holes; S2: Insert the square column body 201 of each impact protection member 20 into the limiting slot 104 in sequence, wherein the extended end 202 is installed on the side of the main body plate 101 close to the road; S3: Align the rear baffle 203 connected by the traction belt 210 with the square column body 201 one by one, and use the fixing bolts 209 to complete the fixation of the rear baffle 203 and the square column body 201 through the fixing holes 208; S4: Push the tailgate 203 and determine whether the anti-impact protective member 20 is pushed into place by checking whether the different-colored identification sticker 205 on the side of the main body 101 away from the road is prominent, thus completing the assembly; S5: Regularly inspect the use of the assembly wall. If the anti-impact protection member 20 is damaged, replace it separately. If a different-colored identification sticker 205 is prominent on the back of the main body plate 101, push the rear baffle 203 to complete the reset.

[0018] After the assembled wall is assembled, if the driver is distracted or the driving route is accidentally scratched or collided, the vehicle can first contact the extended end 202 position, and the car shell will first contact the protective ridge 204 for protection if it is slightly scratched. If this point continues to be stressed, the anti-impact protection member 20 will retract along the limit groove 104. During this period, the square column body 201 is restricted by the position of the limit groove 104, so that the adjustment groove 206 corresponding to the square column body 201 slides along the stop protrusion II 106, and the interference between the stop protrusion II 106 and the stop protrusion I 207 causes the square column body 201 to retract. If the stress continues to be generated, the stop protrusion I 207 at this position can still pass through the stop protrusion II 106 position smoothly due to the smooth chamfer design of the edges of the stop protrusion I 207 and the stop protrusion II 106 and the slight deformation of the square column body 201, while the stop protrusion I 207 at the next position continues to conflict with the stop protrusion II 106 to form a spaced barrier force, and when the impact force is borne by the anti-impact protective member 20, it retracts in the corresponding limit slot 104. This method is not a one-time thing, and the anti-impact protective member 20 will not be damaged by a single impact (except for a major accident impact); At this time, as the anti-impact protective piece 20 at that location retracts, the rear baffle 203 at the end of the anti-impact protective piece 20 moves backward synchronously, and the adjacent anti-impact protective piece 20 is pulled by the traction belt 210 to move in the same direction, and the adjacent anti-impact protective piece 20 is synchronously blocked by the stop protrusion Ⅰ207 and the stop protrusion Ⅱ106 to complete the force unloading effect of the collision stress, so that the anti-impact protective piece 20 adjacent to the collision point has a synchronous protection effect, forming a chain protection. Compared with the traditional rigid block, it not only plays a flexible block (the collision point can be moved backward, instead of maintaining the original position), but also has the force unloading effect of the chain buffer, which avoids excessive force on a single point and requires excessive displacement to buffer, thereby requiring the thickening of the prefabricated wall size to adapt, thereby ensuring the versatility of the prefabricated wall in the place of use.

[0019] Example 2: Based on the assembled wall proposed in Example 1, the present invention provides a further technical solution for the wall main board 10 and the anti-impact protection member 20.

[0020] See also 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 a high color contrast with the square column body 201, and the identification sticker 205 is set as a partition sticker with a color saturation gradient; See also Figure 1 and 6-8, the size of the rear baffle 203 is equivalent to the size of the end of the extension end 202 away from the square column body 201. After the multiple sets of anti-impact protection members 20 are assembled on the position of the wall main board 10, the multiple sets of extension ends 202 and the rear baffle 203 respectively form a continuous wall arranged parallel to the main board 101 on both sides of the main board 101; this installation state is suitable for straight road positions, while if it is at a curved position (such as the corner of a parking lot ramp), the main board 101 can be set into a curved plate with a certain curvature, and the extension end 202 The position is formed to be parallel to the main plate 101 in this state, and the rear baffle 203 position forms a discontinuous surface (but a traction belt 210 is still provided for connection); the length of the square column body 201 is greater than the length of the limiting slot 104, that is, when the anti-impact protection part 20 is assembled on the wall main board 10, the extended end 202 forms the outer facade of the convex main plate 101, and the stop protrusion II 106 is longitudinally provided with a replacement hole 107, and the stop protrusion II 106 and the inner wall of the limiting slot 104 are fixed by bolts through the replacement hole 107.

[0021] When conducting regular inspections on assembly walls, the following maintenance methods can be used based on the inspection results: 1. When inspecting the assembly wall, check from the back side of the wall main board 10 (i.e., the side of the protruding rear baffle 203). If an identification sticker 205 of a color that is significantly different from the color of the rear baffle 203 is found, push the rear baffle 203 at that location to complete the reset of the anti-impact protective element 20 at that point, and check whether the adjacent anti-impact protective element 20 also has an exposed identification sticker 205. If so, complete the reset as well.

[0022] Second, when the rear baffle 203 is pushed to reset the anti-impact protective element 20, the blocking force of the anti-impact protective element 20 during the reset can be clearly felt. Then, it is sufficient to ensure that no identification sticker 205 is exposed on the back side of the wall main board 10. After the reset, the anti-impact protective element 20 at this point can continue to play a protective role. Moreover, even if the collision point is hit again during the inspection interval, if the square column body 201 corresponding to the anti-impact protective element 20 is not completely immersed in the limiting groove 104, it can continue to play a protective role.

[0023] 3. If the blocking force of the anti-impact protective member 20 is weak or there is no obvious blocking force when the rear baffle 20 is pushed to reset the anti-impact protective member 20, the fixing rivet 211 and the fixing bolt 209 corresponding to the anti-impact protective member 20 at that point should be disassembled. After removing the rear baffle 203, the square column body 201 together with the extended end 202 should be pulled out from the limiting groove 104, and the bolts should be removed from the replacement hole 107. The damaged and deformed stop protrusion II 106 should be replaced separately with the same component specifications, and the anti-impact protective member 20 should be assembled in the reverse order of the installation and disassembly sequence.

A method for assembling the prefabricated wall according to any one of claims 1 to 7, characterized in that: The specific assembly steps are as follows: S1: transporting the wall main plate (10) to the location to be installed, using bolts to fix a single main plate (101) on the ground at the installation location through the installation holes, then movably plugging the loading convex rail (102) into the assembly groove (103), sequentially assembling multiple wall main plates (10) into a continuous wall, and using bolts to fix subsequent wall main plates (10) through the installation holes; S2: inserting the square column body (201) of each anti-impact protection member (20) into the limiting slot (104) in sequence, wherein the extended end (202) is mounted on the side of the main body plate (101) close to the road; S3: Align the rear baffle (203) connected by the traction belt (210) with the square column body (201) one by one, and use the fixing bolts (209) to complete the fixing of the rear baffle (203) and the square column body (201) through the fixing holes (208); S4: Push the rear baffle (203) and determine whether the anti-impact protective member (20) is pushed into place by checking whether a different-colored identification sticker (205) is prominent on the side of the main body (101) away from the road surface, thereby completing the assembly; S5: Regularly inspect the use of the assembly wall. If the anti-impact protection member (20) is damaged, replace it separately. If a different-colored identification sticker (205) is prominent on the back of the main plate (101), push the rear baffle (203) to complete the reset.
