Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a paving slab for temporary construction roads. Background Technology

[0002] At construction sites, temporary construction roads are often needed to facilitate the passage of heavy vehicles and construction machinery while protecting the ground from damage. Existing temporary roads mostly use steel plates or simple interlocking paving slabs; however, these solutions have significant drawbacks: First, simple overlapping or splicing structures are unstable and are prone to lateral displacement and end lifting under repeated vehicle pressure, posing a serious safety hazard. Secondly, the poor sealing at the joint between the slabs allows surface water or rainwater to easily seep into the roadbed below, making the road muddy and slippery, affecting traffic efficiency. In severe cases, it can even erode and damage the roadbed, causing potholes in the roadbed below the slab. When vehicles drive over this defect, they can easily bend the slab, which can cause the joint between the slabs to lift up, creating a safety hazard. In addition, the installation and removal of traditional paving slabs is often inefficient and consumes a lot of manpower and time.

[0003] Therefore, developing a temporary construction road paving slab that is stable in connection, waterproof, and easy to install is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, this utility model provides a paving slab for temporary construction roads, which aims to solve the safety hazards caused by water seepage between the existing temporary paving slab and the temporary road, resulting in overall slippage and roadbed erosion.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A paving slab for temporary construction roads, comprising: The paving slab body is provided in multiple sets. The paving slab body is a rectangular plate structure, and an upper connecting plate and a lower connecting plate that are fixedly connected and interlocked on two adjacent sides. A connecting block is fixedly connected to both ends of the lower connecting plate or the upper connecting plate along its length, and the connecting block is provided with threaded holes. The slope slab includes an upper slope slab and a lower slope slab disposed on the outermost side of a plurality of interconnected paving slab bodies, wherein the upper slope slab and the lower slope slab are respectively snapped together with the lower connecting plate and the upper connecting plate. A waterproof mat is installed on the underside of the paving slab body and the slope slab, and the waterproof mat is fixedly connected to the upper slope slab and the lower slope slab. Furthermore, the joint surfaces between the lower connecting plate and the upper connecting plate, between the lower connecting plate and the upper slope plate, and between the upper connecting plate and the lower slope plate all have a labyrinthine structure.

[0006] Furthermore, the upper connecting plate and the lower connecting plate are provided with a groove on the side away from the paving slab body. The length of the groove is distributed along one side of the paving slab body and a snap-fit ​​plate is fixedly connected inside. A snap-fit ​​groove is formed between the snap-fit ​​plate and the side wall of the groove near the paving slab body.

[0007] Furthermore, the upper slope plate is composed of a first straight plate segment and a first inclined plate segment fixedly connected to the outside of the first straight plate segment and distributed downwards from the inside to the outside. A first snap-fit ​​plate and a first sealing plate are fixedly connected to the lower end face of the first straight plate segment. The first snap-fit ​​plate engages with the snap-fit ​​groove on the lower connecting plate, and a first snap-fit ​​groove is formed between the first snap-fit ​​plate and the first sealing plate to engage with the snap-fit ​​plate on the lower connecting plate.

[0008] Furthermore, the lower slope plate is composed of a second straight plate segment, a connecting plate, and a second inclined plate segment. The upper end face of the second straight plate segment is fixedly connected with a second snap-fit ​​plate and a second sealing plate. The second snap-fit ​​plate is engaged with the snap-fit ​​groove on the upper connecting plate, and a second snap-fit ​​groove is formed between the second snap-fit ​​plate and the second sealing plate to engage with the snap-fit ​​plate on the upper connecting plate. The second inclined plate segment is fixedly connected above the second straight plate segment through the connecting plate and is distributed downwardly from the inside to the outside.

[0009] Furthermore, it also includes a fixing assembly for securing connecting blocks on multiple sets of adjacent paving slab bodies.

[0010] Furthermore, the fixing assembly consists of a fixing plate, a sealing gasket, and fixing bolts. The fixing plate and the sealing gasket are connected to the connecting blocks of four adjacent paving slab bodies by fixing bolts, and the sealing gasket is located between the fixing plate and the four connecting blocks.

[0011] Furthermore, the sealing gasket is made of rubber and its size matches the groove formed at the connecting block of the four adjacent paving slab bodies.

[0012] Furthermore, in the fixed state, the upper surface of the fixing plate is flush with the upper surface of the paving slab body.

[0013] Furthermore, the upper and lower slope plates are provided with fixing holes that correspond to the positions of the threaded holes on the connecting block. The two plates are fixed to the connecting block by fixing bolts, and the lower end of the fixing bolts is threaded with a fixing nut for pressing the waterproof gasket.

[0014] Furthermore, the upper surface of the paving slab body is provided with anti-slip protrusions.

[0015] The technical solution provided by this utility model has the following advantages compared with the prior art: 1. Multiple sets of paving slabs are connected by upper and lower connecting plates on adjacent sides, and upper and lower slope plates are connected to the lower and upper connecting plates respectively, which facilitates quick installation and disassembly. In addition, by setting upper and lower slope plates on the outermost side of the paving slab, it is convenient for vehicles to drive, and can also divert water on the surface of the paving slab to the outside. 2. The upper and lower connecting plates, the upper and lower slope plates, and the lower and upper slope plates are all connected by a labyrinthine structure, which extends the seepage path of water and effectively prevents water from seeping down to the surface of the temporary road. In conjunction with the waterproof pad installed under the paving slab, it can further reduce the seepage of water above the paving slab to the temporary construction road below the paving slab, thereby avoiding the safety hazards caused by the paving slab slipping due to mud caused by water seeping into the temporary construction road, as well as the defects such as potholes in the construction road under the main body of the paving slab caused by excessive water accumulation. 3. The waterproof pad is pressed tightly onto the outer side of the paving slab body, the upper slope slab, and the lower slope slab using fixing bolts and nuts, making it easy to operate; 4. The main body of multiple paving slabs is further fixed by fixing plates and fixing bolts to improve the connection strength. Rubber sealing gaskets are set between the fixing plates and multiple connecting blocks to improve the buffering and sealing of the connection between the main body of multiple paving slabs, further reducing the chance of water accumulation on the top of the paving slabs seeping to the bottom.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] like Figures 1-29As shown, this utility model provides a paving slab for temporary construction roads, including multiple sets of paving slab bodies 1. The paving slab body 1 is generally rectangular in shape. One set has a lower connecting plate 2 integrally formed on two parallel sides, and the other set has an upper connecting plate 3 integrally formed on two parallel sides. Adjacent sets of paving slab bodies 1 are connected by the lower connecting plate 2 and the upper connecting plate 3 through a snap-fit ​​connection. It also includes an upper slope plate 4 and a lower slope plate 5. When multiple sets of paving slab bodies 1 are connected to each other, the upper slope plate 4 and the lower slope plate 5 are respectively fixedly connected above the outermost lower connecting plate 2 and below the upper connecting plate 3, so as to facilitate vehicle up and down movement or to drain water accumulated above the paving slab. Furthermore, a maze-like structure with a snap-fit ​​connection is provided between the lower connecting plate 2 and the upper connecting plate 3, between the lower connecting plate 2 and the upper slope plate 4, and between the upper connecting plate 3 and the lower slope plate 5.

[0021] Specifically, in this embodiment, the paving slab body 1 is made of polyethylene material, and its upper surface is provided with V-shaped anti-slip protrusions 101.

[0022] Lower connecting plate 2 as follows Figures 15-18 As shown, the upper and lower sides of the paving slab body 1 are integrally formed, and its length is equal to the length of the upper and lower sides of the paving slab body 1. The upper end face of the lower connecting plate 2 is lower than the upper end face of the paving slab body 1 by a dimension 'a' in the height direction, and the lower end face is flush with the lower end face of the paving slab body 1. A downward groove 201 is provided on the outer side of the lower connecting plate 2, that is, on the side away from the paving slab body 1. Figure 16 As shown, the lower groove 201 has an L-shaped cross-section, that is, it is distributed through the side away from the paving slab body 1. A lower clamping plate 202 is vertically fixed above the bottom surface of the lower groove 201. The length of the lower clamping plate 202 is distributed along the length direction of the upper or lower side of the paving slab body 1 and is formed with lower clamping grooves 203 at intervals with the inner side wall of the lower groove 201 (that is, the side wall near the paving slab body 1).

[0023] The upper connecting plate 3 is integrally formed on the left and right sides of the paving slab body 1. Its length is distributed along the left and right sides of the paving slab body 1. The upper end face of the upper connecting plate 3 is flush with the upper end face of the paving slab body 1. The lower end face is higher than the lower end face of the paving slab body 1 by a dimension a. An upwardly recessed upper groove 301 is also provided on the lower end face of the upper connecting plate 3. Similarly, the cross-section of the upper groove 301 is L-shaped, that is, it is distributed through the paving slab body 1. The upper end face of the upper groove 301 is vertically fixedly connected to the upper snap plate 302. The length of the upper snap plate 302 is distributed along the left or right length direction of the paving slab body 1. Furthermore, the upper snap plate 302 and the side wall of the upper groove 301 near the paving slab body 1 are spaced apart to form upper snap grooves 303.

[0024] Moreover, the shape and size of the lower locking plate 202 and the upper locking groove 303, and the lower locking groove 203 and the upper locking plate 302 are the same, so that the adjacent sides of different paving slab bodies 1 can be connected by locking. The upper connecting plate 3 and the lower connecting plate 2 between the two paving slab bodies 1 serve as connecting parts, and a maze-like joint surface is formed between the upper connecting plate 3 and the lower connecting plate 2.

[0025] In addition, connecting blocks 6 are fixedly connected to both sides of the lower connecting plate 2 and the corners of both sides of the upper connecting plate 3 along the length direction. The connecting blocks 6 are integrally formed with the lower connecting plate 2 or the upper connecting plate 3. The upper end face of the connecting block 6 is flush with the upper end face of the lower connecting plate 2 and the upper end face of the lower groove 301. The lower end face of the connecting block 6 is flush with the lower end face of the lower groove 201 and the lower end face of the upper connecting plate 3. The connecting block 6 is also provided with threaded holes 601 that are distributed vertically. In this embodiment, the length of the connecting block 6 in the length direction of the lower connecting plate 2 is half the width of the upper connecting plate 3, and the length in the length direction of the upper connecting plate 3 is half the width of the lower connecting plate 2, so that when two adjacent paving slab bodies 1 are connected, the sides of the two adjacent connecting blocks 6 fit together.

[0026] Upper slope slab 4 Figures 19-20 As shown, it consists of a first straight plate segment 401 and a first inclined plate segment 402. The first inclined plate segment 402 is fixedly connected to the outside of the first straight plate segment 401 and is distributed at an incline. The thickness of the first straight plate segment 401 is 'a', to ensure that the upper end face of the upper slope plate 4 is flush with the upper end face of the paving slab body 1, and its length is equal to the upper or lower edge of the paving slab body 1 plus twice the width of the upper connecting plate 3. A first snap-fit ​​plate 403 and a first sealing plate 404 are also fixedly connected below the first straight plate segment 401. The size and shape of the first snap-fit ​​plate 403 match the lower snap-fit ​​groove 203, and the two are snapped together. The first sealing plate 404 is fixedly connected below the first straight plate segment 401, and its length is equal to that of the first straight plate segment 401. A first groove 407 is formed between the first sealing plate 404 and the first snap-fit ​​plate 403. The first groove 407 engages with the lower snap-fit ​​plate 202. Furthermore, a first notch 405 is provided on both sides of the length direction of the first sealing plate 404. The shape and position of the first notch 405 match the connecting block 6 so that when the upper slope plate 4 and the lower connecting plate 2 are snapped together, it serves as a space for the connecting block 6 on the paving slab body 1 to avoid interference. In addition, a first fixing hole 406 is provided at the first notch 405 at both ends of the length direction of the first straight plate segment 401. Its position corresponds to the threaded hole 601 so that the upper slope plate 4 and the connecting block 6 can be bolted together.

[0027] Lower slope slab 5 Figures 21-22As shown, it consists of a second straight plate segment 501, a connecting plate 502, and a second inclined plate segment 503. The length of the second straight plate segment 501 is equal to the left or right side of the paving slab body 1 plus twice the width of the lower connecting plate 2, and its thickness is also 'a'. A second snap-fit ​​plate 504 and a second sealing plate 505 are fixedly connected to its lower end face. The size and shape of the second snap-fit ​​plate 504 match the upper snap-fit ​​groove 303, and the two are snap-fitted together. The second snap-fit ​​plate 504 and the second sealing plate 505 are spaced apart to form a A second slot 508 is provided, which engages with the upper locking plate 302. A connecting plate 502 is vertically fixed to the outer side above the second straight section 501 (i.e., the side away from the left or right side of the paving slab body 1). A second inclined section 503 is fixedly connected to the outer side above the connecting plate 502 and is distributed at an angle. Furthermore, the lengths of the second locking plate 504 and the second sealing plate 505 are equal to the lengths of the left or right sides of the paving slab body 1, forming a shape on both sides of the length of the second straight section 501. Figure 21 The second notch 506 shown is shaped and positioned to match the connecting block 6, so as to serve as a receiving cavity for the connecting block 6 when the lower slope plate 5 and the paving plate body 1 are engaged on the left or right side to avoid interference; in addition, second fixing holes 507 are provided on both sides of the second straight plate section 501 along the length direction, corresponding to the positions of the threaded holes 601.

[0028] This device also includes a fixing assembly for connecting adjacent connecting blocks 6 on multiple sets of paving slab bodies 1. The fixing assembly includes a fixing plate 7, a sealing gasket 8, fixing bolts 9, and fixing nuts 10. Figures 1-3 , Figure 5 , Figure 8 as well as Figure 10 As shown, the shape and size of the fixing plate 7 and the sealing gasket 8 match the grooves formed on the upper end faces of the connecting blocks 6 on the four sets of paving slab bodies 1. Four sets of mounting holes are provided on the fixing plate 7 and the sealing gasket 8, each corresponding to a threaded hole 601 on one of the four sets of connecting blocks 6. Furthermore, the size of the mounting holes on the fixing plate 7 matches the head of the fixing bolt 9. Figure 5 and Figure 10 As shown, the fixing bolt 9 passes through the upper fixing plate 7 and the sealing gasket 8 from top to bottom and connects to the threaded hole 601. In the installed state, the fixing plate 7 is flush with the upper end surface of the paving slab body 1, and the head of the fixing bolt 9 does not protrude from the upper end surface of the fixing plate 7. In this embodiment, the sealing gasket 8 is a rubber sealing gasket, which serves as both a buffer and a sealant, reducing the impact at the connection and improving the sealing performance at the connection of multiple paving slab bodies 1.

[0029] In addition, to prevent water from accumulating on the surface of the paving slab and seeping underneath, this device is also equipped with a waterproof pad 11. The waterproof pad 11 is made of high-density polyethylene (HDPE) roll material, such as... Figure 4 and Figure 5 As shown, the waterproof pad 11 is located below the paving slab body 1, the upper slope slab 4, and the lower slope slab 5. Before installation, depending on the number and location of the paving slab body 1 to be laid, through holes corresponding to the positions of the first fixing hole 406 and the second fixing hole 507 can be pre-drilled on the waterproof pad 11. During installation, as... Figure 4 and Figure 7 As shown, firstly, the upper slope plate 4 and the lower slope plate 5 are connected to the paving slab body 1 by fixing bolts 9. After appropriately raising the upper slope plate 4 or the lower slope plate 5, fastening nuts 10 are installed below the waterproof pad 11. The fixing nuts 10 are pressed into the first fixing hole 406 or the second fixing hole 507 on the lower end face of the upper slope plate 4 or the lower slope plate 5, thereby fixing the waterproof pad 11 around.

[0030] The construction process for this device is as follows: First, calculate the number and placement of the paving slabs 1 according to the required construction road. Based on the positions of the fixing holes on the upper slope slab 4 and lower slope slab 5, pre-drill corresponding through holes in the waterproof mat 11, and then lay the waterproof mat 11 on the temporary construction road. Next, place multiple sets of paving slabs 1 on top of the corresponding waterproof mats 11. At this point, the paving slabs 1 are not interlocked. Install the upper slope slab 4 and lower slope slab 5 on the outermost paving slab 1 of the overall paved road. Specifically… The first locking plate 403 on the upper slope plate 4 engages with the lower locking groove 203 on the lower connecting plate 2, and the first locking groove 407 engages with the lower locking plate 202. At this time, the lower end of the first inclined plate section 402 on the upper slope plate 4 is in contact with the ground. At the same time, a labyrinthine joint structure is formed between the first locking plate 403, the first sealing plate 404, the lower locking plate 202, and the lower locking groove 203. The second locking plate 504 on the lower slope plate 5 engages with the upper locking groove 303 on the upper connecting plate 3. The groove 508 engages with the upper snap-fit ​​plate 302. The second snap-fit ​​plate 504, the second sealing plate 505, the upper snap-fit ​​plate 302, and the upper snap-fit ​​groove 303 also form a labyrinthine sealing structure. Furthermore, the upper slope plate 4 and the lower slope plate 5 are fixed to their corresponding connecting blocks 6 by fixing bolts 9 passing through from top to bottom. Next, the paving slab body 1, on which the upper slope plate 4 and the lower slope plate 5 are installed, is raised to a certain height, and fixing nuts are installed at the lower ends of the fixing bolts 9 extending below the upper slope plate 4 and the lower slope plate 5. 10. Press the waterproof pad 11 tightly; finally, the multiple sets of paving slab bodies 1 are snapped together and fixed by the lower connecting plate 2 and the upper connecting plate 3, and the four adjacent connecting blocks 6 between the four sets of paving slab bodies 1 are fixed by the fixing bolts 9 and fixing nuts 10. It should be noted that if the fixing effect of the waterproof pad 11 is further increased, a through hole can be pre-set on the waterproof pad 11 at the location of the fixing plate 7, and a longer fixing bolt 9 can be passed through the through hole to limit the waterproof pad 11 at that position.

[0031] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
