Description

Technical Field

[0001] The present application relates to the technical field of road construction, and in particular to a paving formwork and a construction method using the formwork. Background Art

[0002] The concrete road surface layer is formed by paving a mixture on the roadbed. When paving, formworks need to be arranged on both sides of the road, and the formworks on both sides cooperate to form a paving space for paving the mixture.

[0003] The existing formworks use a large amount of angle irons, angle steels and steel pipes on the outer side of the formworks for support, thus requiring a large amount of materials and a large amount of manpower for installation, resulting in high construction costs and low efficiency. Summary of the Invention

[0004] In order to reduce construction costs and improve efficiency, the present application provides a paving formwork and a construction method using the formwork.

[0005] In a first aspect, a paving formwork provided by the present application adopts the following technical solution:

[0006] A paving formwork includes multiple rows of formwork groups. Adjacent two rows of the formwork groups cooperate to form a paving space for paving the road surface layer. Each formwork group includes a plurality of formwork bodies spliced together in sequence. A plurality of mounting holes are formed in the formwork body along the length direction of the formwork body. Support mechanisms are arranged at the positions of the mounting holes on the formwork body. The support mechanism includes:

[0007] A support steel wire, the support steel wire passes through the mounting hole from the paving space, and two connecting steel wires located on both sides of the formwork body are spaced apart. One of the connecting steel wires passes through the mounting hole and after rotation, the two connecting steel wires abut against the opposite side walls of the formwork body for positioning;

[0008] A fixing component, the fixing component is arranged on the support steel wire and located in the paving space and connected to the roadbed. When the road surface layer is paved, the fixing component is located in the road surface layer.

[0009] By adopting the above technical solution, the template body is installed on the roadbed, and then one of the connecting wires and the supporting wire are passed through the installation holes and rotated, so that the two connecting wires are pressed against the opposite side walls of the template body, and the end of the supporting wire far from the connecting wire extends into the paving space. Then, the supporting wire is fixed to the roadbed through the fixing component to support the template body. Then, the mixture is paved into the paving space, and the paved mixture accumulates on the fixing component and the supporting wire, thereby further improving the supporting effect on the template body. Moreover, when the mixture is compacted later, the pressure on the mixture will be transmitted to the fixing component and the supporting wire, and the supporting wire generates a pulling force on the template body to buffer the extrusion force of the mixture on the template body, so that the two forces form a certain cancellation, thereby further improving the supporting effect on the template body.

[0010] Supported by the supporting wire, a large amount of materials such as angle irons, angle steels and steel pipes are saved. Moreover, the wire material is easy to obtain, the structure is simple and the processing is fast, saving construction time and cost, reducing the construction cost, and at the same time improving the construction efficiency. At the same time, the supporting wire is passed through the installation hole and rotated for positioning, and finally fixed by the fixing component. The process is few and simple, thus reducing the construction personnel required for construction, and therefore reducing the construction cost and the social labor pressure.

[0011] When compacting the edge of the mixture, it is easy to compact the template body, so vibration will be generated on the template body during compaction. The supporting wire has certain toughness and elasticity, so that there is a certain buffering effect between the supporting wire and the template body, reducing the adverse impact of the vibration on the paving quality and improving the construction quality.

[0012] Optionally, the fixing component includes:

[0013] A fixing ring, which is arranged on the supporting wire;

[0014] A fixing nail, which passes through the fixing ring and inserts into the roadbed, and the head presses against the fixing ring for positioning;

[0015] A fixing wire, which is arranged on the fixing ring and presses against the roadbed under the action of the fixing nail.

[0016] By adopting the above technical solution, the fixing ring and the fixing steel wire are pulled close to the roadbed, so that the fixing steel wire presses against the roadbed. Then, the fixing nail is inserted into the roadbed through the fixing ring, and the head of the fixing nail presses against the fixing ring for positioning, so as to realize that the supporting steel wire pulls the template body for positioning. The fixing ring can be formed by bending the supporting steel wire, and the fixing nail, the supporting steel wire and the fixing steel wire are all simple and easy to obtain and fast to process, thus further reducing the construction cost and the social labor pressure, and also improving the construction efficiency. Moreover, after the mixture is piled up on the fixing steel wire for positioning, the fixing steel wire can also disperse the force received by the supporting steel wire, thus further improving the supporting effect on the template body and the construction quality.

[0017] Optionally, there is an avoidance space between the connecting steel wire located on the side of the template body away from the paving space and the template body. The avoidance space is used to make the template body away from the road surface layer when the template body is removed, so as to allow the cutting piece to extend into the cutting support steel wire. A plugging component for plugging the installation hole and supporting the connecting steel wire is arranged on the template body and on the side of the template body away from the paving space.

[0018] By adopting the above technical solution, the fixing component and most of the supporting steel wires are inside the road surface layer, and the connecting steel wire limits the template body, so that it is rather troublesome to remove the template body, and even can only be removed violently. Violent removal is likely to affect the quality of the road surface layer, thus reducing the construction efficiency and quality. At the same time, the installation hole will also cause the mixture to enter, resulting in waste of the mixture. Moreover, after the template body is removed, it will pull the mixture located on the installation hole to move, causing the mixture to fall and making the road surface layer uneven, increasing the construction cost and reducing the construction quality.

[0019] The connecting steel wire is passed through the installation hole from the side close to the paving hole, and then the connecting steel wire is rotated to push the connecting steel wire on the side close to the paving space to press against the template. There is a gap between the other connecting steel wire and the template to form an avoidance space. Then, the plugging component is activated to plug the installation hole, and at the same time, the plugging component presses against the connecting steel wire for support and positioning. During removal, the plugging component is activated to unlock the plugging of the installation hole and at the same time unlock the support for the connecting steel wire, so that the template body can move away from the road surface layer, forming a gap between the template body and the road surface layer. Then, the cutting piece of the cutting tool can be passed through the gap to cut the support steel wire, thus reducing the convenience of removing the template body, improving the construction efficiency, and also reducing the probability of the mixture entering the installation hole, so as to improve the construction efficiency and quality, and at the same time reduce the construction cost.

[0020] Optionally, the plugging component includes:

[0021] Two clamping blocks, the two clamping blocks are clamped and installed on the installation hole, located on both sides of the connecting wire, and seal the installation hole;

[0022] Two sliding blocks, the two sliding blocks are slidably arranged on the two clamping blocks, are inserted and installed together after approaching each other, and can push the connecting wire away from the template body. The sliding block presses against the connecting wire, so that the two connecting wires press against the template body and the sliding block for positioning;

[0023] A fixing screw, the fixing screw passes through one of the sliding blocks and is threadedly connected to the other sliding block for positioning.

[0024] By adopting the above technical scheme, the two clamping blocks are clamped and installed on the installation hole, and the two clamping blocks abut against the support wire for positioning. Then, the two sliding blocks are moved closer to each other at the same time. Therefore, the sliding block pushes the connecting wire away from the template body, so that the two connecting wires respectively press against the template body and the sliding block for positioning. At the same time, the two sliding blocks approach each other, so that the two sliding blocks are inserted and connected together. Finally, the fixing screw is screwed to fixedly connect the two sliding blocks together, so as to seal the installation hole and support the connecting wire at the same time. Moreover, the materials are easy to obtain, the structure is simple and convenient for processing. Therefore, the construction cost is further reduced and the construction efficiency is improved.

[0025] Optionally, the connecting wire located on the side of the template body away from the paving space is detachably installed on the support wire, and a sealing plate for sealing the installation hole and pressing against the template body is arranged on the other connecting wire.

[0026] By adopting the above technical scheme, during installation, the support wire is passed through the installation hole, so that the connecting wire and the sealing plate both press against the template body, so as to seal the installation hole. Then, the other connecting wire is fixedly installed on the support wire, so that the two connecting wires both press against the opposite side walls of the template body. Then, after the fixing component fixes the support wire, paving is carried out. When the template body needs to be removed, the connecting wire is removed, and then the template body can be taken down. Therefore, while supporting the template body, the convenience of removing the template body is greatly improved. Moreover, after the connecting wire passes through the installation hole, there is no need to rotate the support wire, so that the installation of the subsequent fixing component will not be interfered due to rotation, so as to further improve the convenience of installing the template and improve the construction efficiency.

[0027] Optionally, a threaded section is provided on the support wire, and the support wire slidably passes through the connecting wire. Two positioning nuts that are tightened together and press against the connecting wire for positioning are threadedly connected to the threaded section.

[0028] By adopting the above technical solution, the connecting wire is brought close to the supporting wire, so that the supporting wire passes through the connecting wire, and then two positioning nuts are threadedly connected to the supporting wire. First, the positioning nut is screwed to abut against the connecting wire, and finally the latter positioning nut is screwed to abut against the former positioning nut, so as to position the connecting wire. After removing the two positioning nuts, the connecting wire can be removed, thus realizing the detachable connection of the connecting wire. Moreover, the structure is simple, easy to process and operate, reducing the construction cost and improving the construction efficiency.

[0029] Optionally, the supporting wires at the opposite two template bodies located on two adjacent paving spaces are connected and supported together by a bearing assembly. The bearing assembly includes:

[0030] A bearing wire, which is located between the two supporting wires;

[0031] Two bearing cylinders, which are threadedly connected to both ends of the bearing wire and are respectively threadedly connected to the two supporting wires and abut against the positioning nuts for positioning.

[0032] By adopting the above technical solution, during the construction of the road surface layer, it is first paved multiple times, and then other substances are paved or filled again between two paving positions to complete the paving of the entire road surface layer. The opposite two rows of template bodies on two adjacent paving spaces are connected together by a bearing assembly. The two bearing cylinders are threadedly connected to the two supporting wires, so that the two bearing cylinders abut against the two positioning nuts for positioning, so as to realize the support and positioning of the two rows of template bodies and disperse the pressure, making the template bodies in two adjacent template groups connected together, improving the support effect on the templates and the construction quality;

[0033] The bearing cylinder also reduces the probability of the positioning nut falling off the supporting wire, thereby improving the stability of the template. At the same time, when it is necessary to disassemble the template body on which side, only the bearing cylinder connected to it needs to be disassembled, and after disassembly, it is not necessary to cut the exposed supporting wire, because when paving or filling the middle position later, the supporting wire is buried inside, thus further improving the construction convenience, reducing the construction cost and improving the construction efficiency.

[0034] Optionally, two adjacent template bodies are spliced and fixedly connected together by a splicing assembly. The splicing assembly includes:

[0035] Two splicing plates, which are arranged at both ends of the template body;

[0036] A plug-in plate, which is located between the two splicing plates, and sliding blocks are arranged on both ends along the direction of approaching and departing from the splicing plates. The two sliding blocks are respectively plugged and installed on the two splicing plates and are threadedly connected with a plug-in screw rod that abuts against the plug-in plate for positioning.

[0037] By adopting the above technical solution, two template bodies are installed on the roadbed, and then the insertion screw is pushed to drive the insertion block to move, so that the two insertion blocks are inserted and installed on the two fixing plates. Finally, the insertion screw is turned to position the insertion block, and the two ends of the two template bodies are in contact with each other. Finally, the template bodies are fixed by the support mechanism, so as to realize the fixed connection of multiple template bodies, thereby improving the stability of the template and the construction quality.

[0038] Optionally, the insertion plate includes a first insertion portion and a second insertion portion that are rotatably connected together and are respectively connected to the two insertion blocks. A positioning block that is slidably arranged on the second insertion portion is provided on the first insertion portion, and a positioning screw that abuts against the positioning block and is used to position the positioning block is provided on the second insertion portion. When the opposite ends of the first insertion portion and the second insertion portion are pressed together, the first insertion portion and the second insertion portion are parallel to each other.

[0039] By adopting the above technical solution, the first insertion portion and the second insertion portion are parallel in many cases. Therefore, the opposite ends of the first insertion portion and the second insertion portion are pressed together for positioning, thereby improving the stability of the template; when the first insertion portion and the second insertion portion are not parallel, the positioning screw is turned away from the positioning block, and then the angle between the first insertion portion and the second insertion portion is adjusted. After the adjustment is completed, the positioning screw is turned to abut against the positioning block for positioning, so that it can adapt to the positioning of two template bodies in more different situations, improving the convenience during the positioning of the template bodies and the construction efficiency.

[0040] In a second aspect, a construction method provided by the present application adopts the following technical solution:

[0041] A construction method includes the following construction steps:

[0042] A. Installation of the template group: Install multiple rows of template groups on the roadbed, and then fix them through the support mechanism. Adjacent two template bodies in the same template group are connected by a splicing component;

[0043] B. Paving and rolling: Add the mixture into multiple paving spaces for paving, and then roll it to realize the paving of multiple road surface layers;

[0044] C. Film covering and curing: After the rolling is completed, it enters the curing stage, and at the same time, a protective film is covered for protection;

[0045] D. Add the mixture between adjacent two road surface layers for paving, and then roll and perform subsequent film covering and curing to realize the construction of the entire road surface layer.

[0046] By adopting the above technical solution, multiple rows of template groups are installed first, and are supported and positioned by the support mechanism. At the same time, two adjacent template bodies are fixed by the splicing component. Then, the mixture is added to the paving space for paving. In this way, the paving of multiple road surface layers is realized. Then, film covering and curing are carried out. Then, the mixture is added between the two road surface layers, and then paving and film covering and curing are continued. Finally, the construction of the entire road surface layer is completed. For the second paving, there is no need to install templates, and the road surface layer is directly used as a template, which reduces the construction cost and improves the use efficiency and quality.

[0047] In summary, the present application includes at least one of the following beneficial technical effects:

[0048] Supported by the support steel wire, a large amount of materials such as angle irons, angle steels and steel pipes are saved. Moreover, the steel wire material is easy to obtain, the structure is simple and the processing is fast, which reduces the construction cost. At the same time, the construction efficiency is improved, and the processes are few and simple. Therefore, the construction cost and the social labor pressure are reduced; the support steel wire has certain toughness and elasticity, so that there is a certain buffering effect between the support steel wire and the template body, reducing the adverse impact of vibration on the paving quality and improving the construction quality.

Detailed implementation manners

[0057] The following further elaborates on this application Figure 1-7 in conjunction with the attached drawings.

[0058] An embodiment of this application discloses a paving formwork. Embodiment

[0059] Referring to Figure 1 and Figure 2 and, the paving formwork includes multiple rows of formwork groups 1. The adjacent two rows of formwork groups 1 cooperate to form a paving space 12 for paving the mixture. The number of formwork groups 1 can be four groups, thus forming two paving spaces 12. First, the mixture is paved in the two paving spaces 12 to construct a road surface layer, and then the mixture is continuously paved between the two road surface layers to form the entire road surface layer; each formwork group 1 includes a plurality of formwork bodies 11 spliced together in sequence. The formwork body 11 is made of channel steel, and the plurality of formwork bodies 11 are arranged along the length direction of the formwork body 11; a plurality of mounting holes 13 are spaced apart along the length direction of the formwork body 11 on the side wall of the formwork body 11, and a support mechanism 2 is provided at each mounting hole 13 on the formwork body 11.

[0060] Referring to Figure 1 and Figure 2, the installation hole 13 is strip-shaped and its length direction is parallel to the length direction of the template body 11. The support mechanism 2 includes a support wire 21 and a fixing component 3. The support wire 21 horizontally passes through the installation hole 13 from the paving space 12 and extends out of the installation hole 13. Two connecting wires 24 are arranged at intervals along the axis of the support wire 21 on the support wire 21. The two connecting wires 24 are located on both sides of the template body 11 and are in a vertical state. At the same time, the diameters of the support wire 21 and the connecting wires 24 are the same as the width of the installation hole 13, and the connection point of the connecting wire 24 and the support wire 21 is located at the middle position of the connecting wire 24. The length of the connecting wire 24 is less than the length of the installation hole 13, so that the connecting wire 24 can pass through the installation hole 13.

[0061] Refer to Figure 1 and Figure 2 , the connecting wire 24 located on the side of the template body 11 away from the paving space 12 is the first wire 25, and the other connecting wire 24 is the second wire 26; turn the first wire 25 to the horizontal state, and the second wire 26 is also in the horizontal state. Then the first wire 25 can be passed through the installation hole 13, and then rotated 90 degrees so that the first wire 25 and the second wire 26 are turned to the vertical state, so that the first wire 25 and the second wire 26 can press against the opposite side walls of the template body 11 for positioning.

[0062] Refer to Figure 1 and Figure 2 , the support wire 21 includes a connecting part 22 and a support part 23 integrally arranged together. The connecting part 22 is used to connect with the first wire 25 and the second wire 26, and the end of the support part 23 away from the connecting part 22 extends obliquely downward to the side close to the roadbed; the fixing component 3 is arranged on the support wire 21 and is located in the paving space 12 and is connected to the roadbed. When the road surface layer is paved, the mixture will bury the fixing component 3 inside, so that the fixing component 3 is located inside the road surface layer, and the support part 23, part of the connecting part 22 and the second wire 26 are also located inside the road surface layer.

[0063] Refer to Figure 1 and Figure 2, the fixing component 3 includes a fixing ring 31, fixing nails 32 and fixing steel wires 33. The fixing ring 31 is located at one end of the supporting part 23 close to the roadbed, and the fixing ring 31 is formed by bending the supporting part 23; the fixing nails 32 vertically pass through the fixing ring 31 and are inserted into the roadbed, and the heads of the fixing nails 32 are pressed against the fixing ring 31 for positioning. At the same time, the bottom ends of the fixing nails 32 can be inclined away from the template body 11, so that the template body 11 can be tightened when the fixing nails 32 move downward; the fixing steel wires 33 are fixedly installed on the lower surface of the fixing ring 31, and the axis of the fixing steel wires 33 is parallel to the length direction of the template body 11. The fixing steel wires 33 are pressed against the roadbed for positioning under the action of the fixing nails 32; the supporting steel wires 21 and the fixing steel wires 33 can be high-strength steel wires, and the fixing nails 32 can be high-strength cement nails.

[0064] Refer to Figure 1 and Figure 2 , there is a gap between the first steel wire 25 and the template body 11 to form an avoidance space 27. When the template body 11 is removed, the avoidance space 27 facilitates the template body 11 to move away from the road surface layer, so that the cutting blade of the cutting tool can extend in, so as to cut the supporting steel wire 21 located between the second steel wire 26 and the template body 11, thereby facilitating the disassembly of the template body 11; a sealing component 4 is arranged on the template body 11 and on the side of the template body 11 away from the paving space 12. The sealing component 4 is used to seal the installation hole 13 and support and position the first steel wire 25.

[0065] Refer to Figure 1 and Figure 2 , when the template body 11 is used for construction, the sealing component 4 supports the first steel wire 25 and seals the installation hole 13 at the same time. When the template body 11 needs to be removed, the sealing component 4 unlocks the sealing of the installation hole 13 and the support of the first steel wire 25, and then the template body 11 can be moved close to the first steel wire 25 and away from the road surface layer, so that a gap is formed between the template body 11 and the road surface layer. Then, the cutting blade of the cutting tool can be extended into the gap to cut the supporting steel wire 21, thereby improving the convenience of removing the template body 11.

[0066] Refer to Figure 2 and Figure 3 , the sealing component 4 includes two clamping blocks 41, two sliding blocks 42 and a fixing screw 43. The two clamping blocks 41 are clamped and installed on the installation hole 13 from the outside of the paving space 12, and the opposite ends of the two clamping blocks 41 are pressed against the connecting part 22 for positioning. A clamping surface that fits the connecting part 22 is provided on the clamping block 41. The two clamping blocks 41 are used to block the connecting part 22 from moving along the length direction of the template body 11. At the same time, the clamping blocks 41 are flush with the side wall of the template body 11 close to the paving space 12, so as to seal the installation hole 13.

[0067] Refer toFigure 2 and Figure 3 The two sliding blocks 42 are respectively slidably installed on the side wall of the clamping block 41 away from the paving space 12 along the length direction of the mounting hole 13.

[0068] Reference Figure 2 and Figure 3 The two locking parts 46 are integrally arranged on the side walls of the two sliding parts 44 close to the connecting part 22, and a locking block 47 that is plugged into and cooperates with the other locking part 46 is fixedly installed on one of the locking parts 46; the pushing part 45 and the locking part 46 are located on both sides of the first steel wire 25, and the pushing part 45 is located between the first steel wire 25 and the template body 11, and the pushing part 45 is used to push the first steel wire 25 away from the template body 11 to achieve support positioning; the fixing screw 43 passes through one of the locking parts 46 and is threadedly connected to the locking block 47 for positioning, and the fixing screw 43 is used to fix the two locking parts 46.

[0069] Reference Figure 2 and Figure 3 The two sliding parts 44 approach each other, driving the two pushing parts 45 and the two locking parts 46 to approach each other. The two pushing parts 45 push the first steel wire 25 away from the template body 11, so as to support the first steel wire 25, and the locking block 47 is inserted and installed on the locking part 46 for positioning, and then the fixing screw 43 is turned to position the two locking parts 46, thereby achieving the blocking of the installation hole 13 and supporting the first steel wire 25.

[0070] Reference Figure 1 and Figure 4 The two adjacent template bodies 11 in the template group 1 are spliced and fixedly connected together by a splicing assembly 5. The splicing assembly 5 includes two splicing plates 51 and a plug-in plate 52. The splicing plates 51 are fixedly installed on the inner wall of the template body 11, and the splicing plates 51 are in a vertical state. At the same time, splicing plates 51 are arranged at both ends of the template body 11. Splicing grooves are opened on the side walls of the two splicing plates 51 located on the two adjacent template bodies 11 and close to each other on the opposite side.

[0071] Reference Figure 4 and Figure 5, the plug-in board 52 is located between two splicing boards 51. The plug-in board 52 includes a first plug-in part 53 and a second plug-in part 54 that are rotatably connected together by a rotating shaft 55. The rotating shaft 55 is in a vertical state and is located on the side walls of the opposite ends of the first plug-in part 53 and the second plug-in part 54. At the same time, plug-in blocks 58 are slidably installed at the opposite ends of the first plug-in part 53 and the second plug-in part 54, and the plug-in blocks 58 move in the direction of approaching or departing from the splicing board 51. At the same time, the sliding direction of the plug-in blocks 58 is parallel to the length direction of the template body 11. The plug-in blocks 58 are inserted and installed in the splicing grooves for positioning; a plug-in screw 59 is threadedly connected to the plug-in block 58, and the plug-in screw 59 abuts against the first plug-in part 53 and the second plug-in part 54 to position the two plug-in blocks 58. At the same time, kidney-shaped holes 541 for the plug-in screw 59 to pass through are opened on both the first plug-in part 53 and the second plug-in part 54. Push the plug-in screw 59 to drive the two plug-in blocks 58 to be respectively inserted and installed into the two splicing grooves for positioning, and finally turn the plug-in screw 59 for positioning.

[0073] The working principle of the embodiment of the present application is as follows:

[0074] After passing the first steel wire 25 through the mounting hole 13, it is rotated 90 degrees, and then the channel steel is installed on the roadbed, while the fixing steel wire 33 is pressed against the roadbed. Then, the insertion block 58 is inserted and installed on the splicing groove, and finally the insertion screw 59 is screwed to position, so as to realize the connection of two adjacent template bodies 11. Then, the two clamping blocks 41 are clamped and installed on the mounting hole 13, and the pushing parts 45 and locking parts 46 on the two sliding seats 17 are pushed to approach each other. The two pushing parts 45 push the first steel wire 25 away from the template body 11, so that the second steel wire 26 is pressed against the template body 11, and the locking block 47 is inserted and installed on the locking part 46. Finally, the fixing screw 43 is screwed to position. Finally, the fixing nail 32 passes through the fixing ring 31 and is inserted into the roadbed, and the head of the fixing nail 32 is pressed against the fixing ring 31 for positioning, so as to realize the installation and support of the four template groups 1. Then, the mixture is paved in the two paving spaces 12 to form the road surface layer. When the template body 11 needs to be removed, after unscrewing the fixing screw 43, the blocking component 4 is removed, and then the template body 11 is pushed away from the road surface layer, so that a gap is formed between the template body 11 and the road surface layer. Then, the cutting piece is extended into the gap to cut the support steel wire 21, so as to realize the disassembly of the template body 11. Finally, the mixture is paved between the two road surface layers to form the entire road surface layer, thereby reducing the construction cost and improving the construction efficiency and quality.

[0075] Refer to Figure 6 and Figure 7 In this embodiment, the difference from Embodiment 1 is that the first steel wire 25 is detachably installed on the connecting part 22, and a blocking plate 14 pressed against the mounting hole 13 is fixedly installed on the second steel wire 26. The blocking plate 14 is located on the side of the template body 11 close to the paving space 12. At the same time, the blocking plate 14 is in a horizontal state and is used to completely block the mounting hole 13. A threaded section is provided on the connecting part 22, and a connecting hole 15 is provided on the first steel wire 25. The connecting part 22 slidably passes through the connecting hole 15. Two positioning nuts 16 that abut against each other for positioning are threadedly connected to the threaded section. One of the positioning nuts 16 abuts tightly against the first steel wire 25 for positioning, so that the first steel wire 25 and the second steel wire 26 are pressed tightly against the opposite side walls of the template body 11 for positioning.

[0077] Refer to Figure 6 and Figure 7 Two bearing cylinders 62 are coaxially and threadedly sleeved on both ends of the bearing wire 61, and the bearing cylinder 62 is threadedly connected to the two connecting parts 22. At the same time, the bearing cylinder 62 abuts against the positioning nut 16 on the side far from the first wire 25 for positioning, so as to support the two template bodies 11 located in the middle position. Moreover, when the template body 11 needs to be disassembled, the two bearing cylinders 62 can be removed from the two connecting parts 22.

[0078] The working principle of the embodiment of the present application is as follows:

[0079] Pass the connecting part 22 through the paving space 12 and the mounting hole 13, then pass the connecting part 22 through the first wire 25, and then thread the two positioning nuts 16 onto the connecting part 22 so that the two positioning nuts 16 abut against each other and the positioning nut 16 abuts against the first wire 25 for positioning, so that the first wire 25 and the second wire 26 are pressed against the opposite side walls of the template body 11, so as to position the template body 11. Then, the fixing component 3 positions the connecting part 22, so as to install the four-row template group 1. Then, screw the two bearing cylinders 62 threadedly connected to the two connecting parts 22 so that the bearing cylinder 62 abuts against the positioning nut 16 for positioning, so as to support and position the adjacent two template groups 1. Then, add the mixture to the two paving spaces 12 for paving to form the road surface layer. When the template body 11 needs to be removed, screw the bearing cylinder 62 to remove the bearing assembly 6, and then remove the two positioning nuts 16 and the first wire 25 in sequence, and then the template body 11 can be removed. Then, add the mixture between the road surface layers to form the entire road surface layer, and the exposed support wire 21 is buried in the road surface layer, so as to improve the construction quality and efficiency.
