[0028] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] First, some technical terms in the present application are explained to facilitate those skilled in the art to understand the present application.

[0030] Magnetic box: usually composed of a steel shell and a magnetic core. Its main function is to measure the tension of prestressed steel bars through magnetic sensors and help workers control the size and balance of prestress.

[0031] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0032] In a first aspect, an embodiment of the present application provides a prefabricated road slab.

[0033] Reference Figure 1 , Figure 1 Schematic diagram of the prefabricated road slab in the embodiment of the present application. Figure 1 As shown, in one embodiment, the prefabricated road slab includes a road slab body 1. During construction, multiple road slab bodies 1 are placed on the construction site, and two adjacent road slab bodies 1 are spliced ​​in sequence to form a construction road to meet the traffic requirements of large vehicles.

[0034] Specifically, the road plate body 1 includes two sets of opposite side walls, each of which is provided with a reserved groove 11 and a reserved hole 12, and the reserved groove 11 and the reserved hole 12 of each side wall are respectively arranged corresponding to the reserved hole 12 and the reserved groove 11 of the opposite side wall, the reserved groove 11 is a groove on the top of the plate, and a force transmission rod 2 is detachably arranged in the reserved hole 12. When two adjacent road plate bodies 1 are spliced, one end of the force transmission rod 2 is located in the reserved hole 12 of the side wall of the current road plate body 1, and the other end is located in the reserved groove 11 of the side wall of the spliced ​​road plate body 1.

[0035] Among them, the two groups of opposite side walls of the road plate body 1 can be a group of opposite side walls in the transverse direction and a group of opposite side walls in the longitudinal direction, so that the construction road opened up by splicing multiple road plate bodies 1 is relatively regular, which is convenient for large vehicles to travel. The reserved groove 11 can be a rectangular groove, and it is a groove on the top of the plate. The reserved hole 12 can be a square hole or a round hole, and a force transmission rod 2 is detachably arranged in the hole. The cross-sectional shape of the force transmission rod 2 should be similar to the hole shape of the reserved hole 12, and the cross-sectional dimensions of the force transmission rod 2 are smaller than the cross-sectional dimensions of the reserved groove 11 and the cross-sectional dimensions of the reserved hole 12, ensuring that the force transmission rod 2 can smoothly enter and exit the reserved groove 11 and the reserved hole 12. The reserved grooves 11 and reserved holes 12 on a group of opposite side walls of the road plate body 1 should be arranged correspondingly, for example: a group of opposite side walls of the road plate body 1 is the left and right side walls, the reserved hole 12 located on the left side wall corresponds to the reserved groove 11 located on the right side wall; the reserved groove 11 located on the left side wall corresponds to the reserved hole 12 located on the right side wall. When two adjacent road plate bodies 1 are spliced, the reserved hole 12 of the side wall of the current road plate body 1 should be kept in a straight line with the reserved groove 11 of the side wall of the road plate body 1 to be spliced ​​(that is, the other road plate body 1 to be spliced ​​with the current road plate body 1), and at the same time, the force transmission rod 2 is pulled out so that one end of it is located in the reserved hole 12 of the current road plate body 1, and the other end is located in the reserved groove 11 of the side wall of the road plate body 1 to be spliced; similarly, the reserved hole 12 of the side wall of the road plate body 1 to be spliced ​​is also performed in this way.

[0036] In this embodiment, when two adjacent road slab bodies 1 are spliced, one end of the force transmission rod 2 is located in the reserved hole 12 of the side wall of the current road slab body 1, and the other end is located in the reserved groove 11 of the side wall of the spliced ​​road slab body 1. This splicing form is relatively simple, reliable, and has good integrity. In addition, after the construction is completed, it is also convenient to dismantle the road slab body 1 and reuse it, which is conducive to reducing construction costs and reducing construction waste.

[0037] In addition, by setting the road slab body 1 into two groups of opposite side walls, and making the reserved grooves 11 and reserved holes 12 of each side wall correspond to the reserved holes 12 and reserved grooves 11 of the opposite side walls, the two adjacent road slab bodies 1 can meet the most basic splicing conditions while simplifying the construction process and improving the construction efficiency. By setting the reserved grooves 11 as slots on the top of the plate, it is convenient for the staff to observe the pull-out distance of the force transfer rod 2, and it is beneficial to control the connection accuracy between the two adjacent road slab bodies 1. By detachably setting the force transfer rod 2 in the reserved holes 12 instead of fixing it to the side wall where it is located, it is convenient to transport the road slab body 1. At the same time, it can also prevent the force transfer rod 2 from being hit or bent during transportation, thereby affecting the subsequent splicing. Through this embodiment, the technical problem that the cast-in-place access road in the prior art not only affects the construction period, but can also be used once, wasting manpower and material resources is solved.

[0038] Further, in one embodiment, referring to Figure 2 , Figure 2 for Figure 1 A side view of the middle road slab body 1. Figure 2 As shown, the reserved grooves 11 and the reserved holes 12 of each side wall are at the same level. In this embodiment, by placing the reserved grooves 11 and the reserved holes 12 of each side wall at the same level, the difficulty of splicing is reduced and the construction efficiency is improved. In addition, the reserved grooves 11 and the reserved holes 12 of each side wall are arranged alternately, which also helps the road plate body 1 to achieve uniform force distribution and avoid damage to the side wall of the road plate body 1 due to excessive local force.

[0039] Furthermore, in one embodiment, the depth of the reserved hole 12 is greater than the depth of the reserved groove 11. In this embodiment, the depth of the reserved hole 12 is greater than the depth of the reserved groove 11, in order to allow the dowel rod 2 to be fully inserted into the reserved hole 12. At the same time, during splicing, the end of the dowel rod 2 that has been inserted into the reserved hole 12 in advance will not affect the splicing of the two road slab bodies 1 to be spliced, so that the two road slabs are easily aligned.

[0040] Further, in one embodiment, if Figure 1 and Figure 2 As shown, the road plate body 1 is a cube, the reserved hole 12 is a circular hole, the reserved groove 11 is a rectangular groove, and the bottom of the reserved hole 12 and the bottom of the reserved groove 11 of each side wall are both located in the middle of the side wall. In this embodiment, the road plate body 1 is a cube, which can be a rectangular parallelepiped or a cube. Such a structure is relatively simple, easy to manufacture and lay, and can make the road plate body 1 closely arranged during laying, reducing gaps and improving the flatness and stability of the road. The reserved hole 12 is a circular hole, and the reserved groove 11 is a rectangular groove. By setting the bottom of the reserved hole 12 and the bottom of the reserved groove 11 of each side wall in the middle of the side wall, it helps to maintain the balance and stability of the road plate body 1 structure and reduce structural deformation and damage caused by uneven load distribution.

[0041] Further, in one embodiment, referring to Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the installation conditions of two adjacent road slab bodies 1 in the embodiment of the present application; Figure 3 Schematic diagram of the use of two adjacent road slab bodies 1 in the embodiment of the present application. Figure 3 and Figure 4As shown, a handle 21 perpendicular to the shaft of the force transmission rod 2 is provided at one end close to the reserved slot 11, and a receiving slot 121 for receiving the handle 21 is provided upwardly at the opening of the reserved hole 12. In this embodiment, by providing a handle 21 perpendicular to the shaft of the force transmission rod 2 at one end close to the reserved slot 11, and providing a receiving slot 121 for receiving the handle 21 upwardly at the opening of the reserved hole 12, it is convenient for construction workers to pull the force transmission rod 2 in and out, and the alignment between two adjacent road slab bodies 1 will not be affected, thereby shortening the construction period and improving the overall efficiency.

[0042] Further, in one embodiment, if Figure 3 and Figure 4 As shown, the handle 21 is not higher than the top surface of the road plate body 1 where it is located. In this embodiment, by setting the handle 21 not higher than the top surface of the road plate body 1 where it is located, the risk of collision between pedestrians or vehicles and the handle 21 can be reduced, potential traffic accidents and injuries can be reduced, and the overall safety of road use can be improved. At the same time, the handle 21 can also be prevented from being damaged by external impact (such as wheel rolling, etc.), thereby extending its service life and reducing maintenance costs.

[0043] Furthermore, in one embodiment, the top edge of the road slab body 1 is provided with an angle steel edging. In this embodiment, by providing the top edge of the road slab body 1 with an angle steel edging, the strength and stability of the top edge of the road slab body 1 can be enhanced to prevent damage and deformation caused by long-term vehicle rolling, pedestrian trampling, and natural environmental factors (such as weathering, corrosion, etc.).

[0044] Further, in one embodiment, if Figure 1 As shown, the top of the road plate body 1 is provided with a plurality of hanging nails 3 for hanging the road plate body 1. In this embodiment, by providing a plurality of hanging nails 3 for hanging the road plate body 1 on the top of the road plate body 1, it is convenient to place the road plate body 1 at a specified position and to control the accuracy of its splicing.

[0045] In some other embodiments, the road slab body 1 is composed of a concrete slab and two layers of steel mesh embedded in the concrete slab. The steel mesh also includes a plurality of transverse bars and a plurality of longitudinal bars tied together, and radial bars are provided at the four corners of the steel mesh to reinforce the steel mesh, so that the structure of the road slab body 1 is more stable and not easy to break.

[0046] In a second aspect, the present application provides a method for manufacturing a prefabricated road slab.

[0047] In one embodiment, referring to Figure 5 , Figure 5 for Figure 1 A schematic diagram of the manufacturing method of the prefabricated road slab. Figure 5As shown, the manufacturing method of the prefabricated road slab includes:

[0048] Step S10, placing the prefabricated formwork on the formwork platform, and then placing the steel bar skeleton into the prefabricated formwork.

[0049] In this embodiment, the prefabricated formwork can adopt a standard steel formwork, which includes four side forms. After the side forms are assembled, they are placed on a pre-leveled formwork platform. The side forms are connected by bolts, and the side forms are connected to the formwork platform by a magnetic box to ensure that all connections are firm. In addition, before assembling the formwork, the residues and debris on the surface must be cleaned to ensure that the surface is smooth and rust-free, and then the release agent is evenly applied. Among them, the magnetic box in this embodiment is composed of a steel shell and a magnetic core. Its main function is to measure the tension of the prestressed steel bars through a magnetic sensor and help workers control the size and balance of the prestress.

[0050] Prefabricated road slabs use double-layer steel mesh to form a steel skeleton, and the steel mesh also includes a number of transverse and longitudinal bars tied together, and radial bars are provided at the four corners of the steel mesh to reinforce the steel mesh. First, manual binding is carried out in the steel processing area, and after acceptance, the whole is moved into the prefabricated formwork; when binding the steel bars, the spacing between the transverse and longitudinal bars and the spacing between the two layers of mesh should be strictly controlled. When binding the steel mesh, the wires should be tied in a plum blossom shape with intervals, and the binding should be firm and the excess wires should extend to the inside of the steel cage; cement mortar pads are used to control the thickness of the steel protection layer, and the pad spacing can be 0.8m. The steel protection layer refers to the distance from the outer edge of the outermost steel bar to the concrete surface.

[0051] In this embodiment, by placing the precast formwork on the formwork platform and then placing the steel bar skeleton into the precast formwork, it is ensured that the cast concrete structure has an accurate shape and size and meets the design requirements; the combined use of the precast formwork and the steel bar skeleton makes the concrete structure more stable during the casting process and reduces structural problems caused by improper construction.

[0052] Step S20, before pouring concrete, respectively install the embedded parts corresponding to the reserved grooves 11 and the reserved holes 12 at the specified positions of the prefabricated template, and seal the openings of the embedded parts with blind plates.

[0053] In this embodiment, before pouring concrete, it is necessary to plan the positions of each reserved groove 11 and each reserved hole 12 in the precast template in advance, and mark them on the side template of the precast template as the specified positions. And the corresponding embedded parts of the reserved grooves 11 and reserved holes 12 are installed at the specified positions of the precast template. For example, if the reserved groove 11 is a rectangular groove, a rectangular channel steel is installed as an embedded part; if the reserved hole 12 is a round hole, a round steel pipe is installed as an embedded part. The connecting steel bars are connected to the steel mesh as a whole, and the connecting steel bars should be welded to ensure a secure connection. During the installation of the embedded parts, the position accuracy of the embedded parts must be strictly controlled, and blind plates must be set at the openings of the embedded parts for effective sealing to prevent concrete from flowing into the interior of the embedded parts during the pouring process.

[0054] In other embodiments, if the force transmission rod 2 has a handle 21, an open rectangular groove is reserved at the end of the embedded part corresponding to the reserved hole 12, so that the handle 21 of the force transmission rod 2 can be fully extended into the interior of the road plate body 1 later.

[0055] In some other embodiments, if the hanging points of the prefabricated road slabs adopt the process of embedding the hanging nails 3, it is necessary to use rubber balls matching the hanging nails 3 to fix the hanging nails 3 before pouring the concrete, and then fix the rubber balls on the side molds through the limit frames to prevent displacement during concrete pouring. The rubber balls are removed after the concrete is formed.

[0056] In some other embodiments, if the top edge of the prefabricated road slab is provided with angle steel edging, it is also necessary to plan the position of the angle steel in the prefabricated formwork in advance before pouring the concrete, and mark it on the side formwork of the prefabricated formwork as the specified position, and install the angle steel at the specified position.

[0057] Step S30, pouring concrete in the prefabricated formwork and performing curing to obtain a prefabricated road slab.

[0058] In this embodiment, concrete is poured into the prefabricated formwork using a hopper, and an inserted vibrator is used for manual vibration, but the vibrator should be prevented from colliding with the prefabricated formwork and the steel bars. When vibrating, the concrete is vertically inserted into the concrete, and the vibrator is inserted quickly and pulled out slowly to avoid leaving pores, until the concrete no longer sinks significantly, no bubbles appear, and the slurry begins to overflow. After the concrete is poured, the surface is smoothed and anti-skid patterns are drawn in time, the depth of the anti-skid patterns is 2 to 3 mm, and it is covered with water for curing, and the curing time of watering shall not be less than 14 days, and finally the prefabricated road slab is obtained.

[0059] In a third aspect, an embodiment of the present application provides a method for installing a prefabricated road slab based on any one of the above embodiments.

[0060] In one embodiment, the method for installing the prefabricated road slab includes:

[0061] Place another road slab body 1 next to the current road slab body 1, so that the reserved groove 11 of the current road slab body 1 and the reserved hole 12 of the road slab body 1 to be joined are located in the same straight line, and the reserved hole 12 of the current road slab body 1 and the reserved groove 11 of the road slab body 1 to be joined are located in the same straight line; pull out the force transmission rod 2 from the reserved hole 12 and place it in the opposite reserved groove 11; splice in sequence until all road slab bodies 1 are spliced.

[0062] In this embodiment, the force transfer rod 2 is first made. The force transfer rod 2 can be made of hot-rolled round steel bars. The length of the force transfer rod 2 should be less than the depth of the reserved hole 12 to ensure that the end of the force transfer rod 2 does not exceed the edge of the road slab body 1. This can ensure that no large gap will be generated between the two road slabs to be spliced. Before the prefabricated road slabs are spliced, the force transfer rod 2 is first inserted into the reserved hole 12 of the road slab body 1. Otherwise, after the two road slabs are aligned, it will be difficult to insert the force transfer rod 2, which will hinder the subsequent splicing.

[0063] Secondly, according to the on-site use requirements, several prefabricated road panels should be spliced ​​together to meet the traffic needs of large vehicles. When two adjacent road panel bodies 1 are spliced, another road panel body 1 is placed next to the current road panel body 1, so that the reserved groove 11 of the current road panel body 1 and the reserved hole 12 of the road panel body 1 to be spliced ​​are located in the same straight line, and the reserved hole 12 of the current road panel body 1 and the reserved groove 11 of the road panel body 1 to be spliced ​​are located in the same straight line. In this way, a "channel" for the horizontal sliding of the force transmission rod 2 can be formed between the reserved groove 11 and the reserved hole 12. At this time, the force transmission rod 2 is pulled out from the reserved hole 12 and placed in the relative reserved groove 11. This method is repeated repeatedly and spliced ​​in sequence until all road panel bodies 1 are spliced. The construction road spliced ​​in the above manner not only has good integrity, the prefabricated road panels can be reused, but also the construction efficiency has been greatly improved, saving costs.

[0064] In addition, if a handle 21 perpendicular to the rod body is provided at one end of the force transmission rod 2 near the reserved groove 11, the length of the handle 21 shall not be higher than the top surface of the road plate body 1, otherwise it will affect driving safety. A DN25 steel pipe can be inserted into the handle 21, and the force transmission rod 2 can be pulled out of the reserved hole 12 until it contacts the inner wall of the reserved groove 11 of the road plate body 1 to form a whole with two adjacent road plate bodies 1.

[0065] Finally, medium-coarse sand may be used to fill the gap between the force transmission rod 2 and the reserved groove 11 to form a stable whole.
