Description

Technical Field

[0001] This application relates to the field of road construction, and particularly to a prefabricated road module for rapid assembly. Background Art

[0002] In the field of road construction, the traditional road construction process usually includes multiple steps such as pre-construction preparation, trench excavation, drainage pipeline construction, pipe pit backfilling, subgrade construction, and pavement structure construction. This requires on-site concrete pouring, has a long construction period, and is greatly affected by weather conditions. Especially in cities, the problems of traffic congestion and environmental pollution caused by construction are particularly prominent.

[0003] Existing technologies for splicing roads with prefabricated road units, although improving the construction efficiency to a certain extent, still have some drawbacks. First, the splicing process of prefabricated road units is complex, requiring a large amount of manual and mechanical operations, resulting in high construction costs. Second, it is difficult to control the accuracy during the splicing process, and problems such as uneven splicing and excessive gaps are likely to occur, affecting the flatness and service life of the road. In addition, traditional prefabricated road units lack flexibility during the splicing process and are difficult to adapt to complex road design and construction environments.

[0004] In view of the above related technologies, improvements are made to the prefabricated road module in the direction of rapid assembly. Without affecting the strength of the prefabricated module, some mechanisms are designed on the prefabricated module to simplify the construction process, reduce the use of labor and machinery, and improve the accuracy and quality of splicing. Summary of the Invention

[0005] In order to simplify the construction process and improve the accuracy and quality of splicing, this application provides a prefabricated road module for rapid assembly.

[0006] The prefabricated road module for rapid assembly provided by this application adopts the following technical solutions:

[0007] A prefabricated road module for rapid assembly, including a prefabricated component, further including:

[0008] Side holes, horizontally opened on two opposite side walls in the length direction of the prefabricated component, the two side holes are symmetrically distributed and not connected, and a plurality of the side holes are equally spaced along the side of the prefabricated component;

[0009] Steel bar holes, horizontally penetrating through the bottom walls of a plurality of side holes, a plurality of the steel bar holes are equally angularly distributed along the circumferential direction of the bottom walls of the side holes, steel bars are inserted into the steel bar holes, and one end of each steel bar protrudes from the side hole; the steel bar holes on both sides of the prefabricated component are alternately distributed so that there is no interference when the side edges of the two prefabricated components are abutted;

[0010] Side blocks are formed at the bottom sides of the two side edges of the precast member, protruding from the bottom wall of the precast member, and the distance between the two side blocks is equal to the width of the top side of the precast member.

[0011] By adopting the above technical solution, the steel bar holes are used for inserting steel bars. The steel bars extend out from the steel bar holes, and at most the ends of multiple steel bars protrude into the side holes. The steel bars penetrate completely to improve the self-structural strength of the reinforced concrete precast member. In road construction, the width of the road requires the side edges of multiple precast members to be abutted. Therefore, the steel bar holes on the two sides are staggered so that the steel bars on both sides are distributed alternately, so that the steel bars are inserted into each other when the side edges of the two precast members are abutted. Therefore, in the above solution, side holes with a preset length are opened on the side edges of the precast member, and the steel bar holes are opened in the side holes to ensure that the steel bars are inserted into the side holes during insertion, and to avoid interference between their ends and the side edges of the precast member.

[0012] The opening of the side blocks is used for positioning in the horizontal plane of the precast member. After the installation of the lower precast member is completed, the upper precast member can be directly positioned through the side blocks, improving the efficiency of road construction.

[0013] Optionally, the top end of the side block is lower than half of the height of the side edge of the precast member.

[0014] By adopting the above technical solution, when the side edges of multiple precast members are abutted, a gap, that is, a splicing joint, needs to be reserved between the top side edge of the side block and the top side wall of the precast member for pouring concrete slurry.

[0015] Optionally, the bottom end of the side block on one side of the precast member is higher than the bottom side wall of the precast member, and the top wall of this side block is flush with the bottom wall of the other side block.

[0016] By adopting the above technical solution, when the side edges of the precast member are fitted, the side block of one precast member is completely fitted with the corresponding side block of the other precast member.

[0017] Optionally, the end faces of multiple steel bars are flush with the side wall of the side block.

[0018] By adopting the above technical solution, the lengths of the end faces of the steel bars are unified. Considering the side hole insertion structure, too long end faces of the steel bars will increase the length of the side holes inside the precast member and reduce the structural strength. Moreover, when the precast member is transported, the surface of the side block is flush with the end faces of the steel bars, which is more convenient for transportation.

[0019] Optionally, gaps are opened between the two end parts of the side block and the corresponding end parts of the precast member.

[0020] By adopting the above technical solution, the assembly and joining of precast components need to be transported by lifting tools such as electric hoists. The side block structure cannot bear a large weight. Therefore, the two side blocks of the precast component cannot directly install and dock the lifting parts of the lifting tool. So, the length of the side block needs to be shorter than the length of the precast component, and the part without the side block is used to install the above-mentioned lifting parts.

[0021] Optionally, it further includes:

[0022] Installation rings, vertically arranged and sleeved on both ends of the precast component. The distance between the installation rings is greater than the length of the side block. Grooves adapted to the installation rings are opened on the multi-side side walls of the precast component to make the outer ring surface of the installation ring flush with the surface of the precast component; a rope groove is opened on the ring surface of the installation ring parallel to the length direction of the installation ring.

[0023] By adopting the above technical solution, to ensure the tight fit of the precast component, the installation ring cannot protrude from the outer surface of the precast component. Before installing the precast component in road construction, construction workers need to install the steel wire rope in the rope groove first and install the top end of the steel wire rope on the lifting tool.

[0024] Optionally, the height of the top wall of the side block on one side of the precast component is higher than the height of the bottom of the side hole, and a fan-shaped groove adapted to the side hole is opened at the top of the side block.

[0025] By adopting the above technical solution, after the side edges of the precast component are fitted, in addition to pouring concrete to seal the gap, it is also necessary to fill the side holes of the precast component to improve the structural strength. In the above solution, the concrete slurry flows into the side holes along the fan-shaped groove to seal the side holes.

[0026] Optionally, the bottom wall of the fan-shaped groove is inclined towards the side close to the precast component.

[0027] By adopting the above technical solution, the inclination of the bottom wall of the fan-shaped groove improves the efficiency of the concrete slurry flowing into the side holes.

[0028] In summary, the present invention has at least the following beneficial effects:

[0029] 1. Due to the design of side holes and steel bar holes, the splicing of precast road modules is made simpler and faster, while ensuring accuracy and quality;

[0030] 2. Through the special design of side blocks and installation rings, the present invention improves the flexibility of splicing and can adapt to more complex road designs and changing construction environments. Description of the Drawings

[0036] The following further elaborates on the present application in conjunction with the attached Figures 1-4 drawings.

[0037] An embodiment of the present application discloses a precast road module for rapid assembly. Referring to Figure 1 , a precast road module for rapid assembly includes a precast component 1 body. During road construction, the length directions of multiple precast components 1 are parallel to the length direction of road paving, and are composed of pressing the two ends in the length direction and the two sides in the width direction of multiple precast components 1 against each other and pouring concrete slurry into the splicing seam.

[0038] Referring to Figure 1 and Figure 2 , a plurality of side holes 11 are symmetrically opened at the two side edges in the width direction of the precast component 1. The two side holes 11 are horizontally opened and are equally spaced along the length direction of the precast component 1; a plurality of steel bar holes 12 are opened on the bottom wall of each side hole 11, so that the bottom wall of the side hole 11 has a "coal ball type" structure. The plurality of steel bar holes 12 in each side hole 11 are circumferentially distributed at equal angles. Steel bars 121 are inserted into the steel bar holes 12. The steel bars 121 have the same length and the ends protrude from the side wall edge of the precast component 1; the distribution states of the steel bar holes 12 on the same side edge of the precast component 1 are the same, and the steel bar holes 12 on different side edges are staggered, so that the steel bars 121 on different side edges of the precast component 1 are alternately distributed. When the two opposite side edges of two precast components 1 are attached and spliced, the steel bars 121 are inserted into the side holes 11, and the multiple steel bars 121 from the two precast components 1 in the same side hole 11 are distributed on a circumferential line.

[0039] Referring to Figure 2 and Figure 3In this embodiment, two side blocks are formed on the two opposite side edges of the prefabricated component 1. The length direction of the two side blocks is parallel to the length direction of the prefabricated component 1. The structures and distributions of the two side blocks are different, but the lengths of the two side blocks are the same, both shorter than the length of the prefabricated component 1, so that there are parts at both ends of the length direction of the prefabricated component 1 without the two side blocks. For ease of explanation, the two side blocks are respectively a first side block 13 and a second side block 14; the top wall of the first side block 13 is lower than half of the side of the prefabricated component 1, and the bottom wall is higher than the side of the prefabricated component 1, so that the bottom wall of the first side block 13 does not protrude from the bottom wall of the side block, or in other words, a specific gap is provided between the bottom wall of the first side block 13 and the bottom wall of the prefabricated component 1; the top wall of the second side block 14 is flush with the bottom wall of the first side block 13, that is, the second side block 14 is higher than the bottom wall of the prefabricated component 1, and the height difference is equal to the height of the above-mentioned specific gap, and the bottom wall of the second side block 14 is lower than the bottom wall of the prefabricated component 1, so that there is a portion of the second side block 14 protruding from the bottom wall of the prefabricated component 1.

[0040] In order to ensure the stable fixation of the second side block 14, the second side block 14 needs to have a portion connected to the prefabricated component 1, that is, the height of the above-mentioned specific gap needs to reach a height that makes the structure of the second side block 14 stable and unbroken. The second side block 14 is flush with the two walls of the first side block 13, so that when two adjacent prefabricated components 1 are fitted, the two side blocks are stably fitted, and a joint is formed between the two adjacent prefabricated components 1 for pouring concrete. The protruding structure of the second side block 14 can be used to position the laying of the prefabricated components 1. After the laying of the lower prefabricated components 1 is completed, a proper amount of concrete slurry is poured between the adjacent prefabricated components 1, that is, in the gap above the first side block 13, and the protruding structure of the second side block 14 is used to clamp the gap above the first side block 13 to complete the positioning of the upper prefabricated component 1.

[0041] Reference Figure 2 and Figure 3 One end of the multiple steel bars 121 extending out of the side hole 11 is flush with a side wall of the side block away from the prefabricated component 1, so as to limit the length of the steel bars 121, facilitate transportation and reduce the opening depth of the side hole 11.

[0042] Reference Figure 2 and Figure 3, in this embodiment, the top wall portion of the first side block 13 is higher than the bottom edge portion of the side hole 11. A fan-shaped groove 131 is provided on the top wall of the first side block 13 corresponding to each side hole 11. The bottom of the fan-shaped groove 131 is arc-shaped, and its radius is equal to the radius of the side hole 11, so that the fan-shaped groove 131 can be used as an extension of the hole wall of the side hole 11. When grouting into the splicing seam, the concrete slurry can flow into the side hole 11 along the fan-shaped groove 131 to fill the side hole 11. To further improve the filling of the side hole 11 by the concrete slurry and the flow efficiency along the fan-shaped groove 131, in this embodiment, the bottom of the fan-shaped groove 131, or the top wall of the side block is inclined downward toward the side close to the precast member 1 to apply a gravity force to the concrete slurry.

[0043] Refer to Figure 2 With Figure 3 , engaging grooves 15 are provided in the portions of the two ends of the above-mentioned precast member 1 where the side blocks are not formed. The engaging grooves 15 are provided on all four side walls and are connected, so that the engaging grooves 15 are annular. An installation ring 151 is sleeved in the engaging grooves 15. The height of the installation ring 151 is equal to the height of the engaging grooves 15. When the precast member 1 is cast, the installation ring 151 needs to be pre-placed in the mold in advance and integrally formed with the precast member 1. The ring surface of the installation ring 151 is vertical and perpendicular to the length direction of the precast member 1. A rope groove 152 is provided on the surface of the installation ring 151 parallel to the length direction of the installation ring 151 for installing a steel wire rope to facilitate the transportation by a lifting tool.

[0044] The implementation principle of a precast road module with quick assembly in an embodiment of the present application is as follows: Construction workers pre-transport the precast member 1 to the road construction site, tie the steel wire ropes to the rope grooves 152 at both ends of the precast road module, fix the top ends of the steel wire ropes to the lifting tool, and transport them through the lifting tool.

[0045] When laying the precast member 1, it is positioned by relying on the first side block 13, so that the two length side edges of two adjacent precast members 1 are abutted, the steel bars 121 on the opposite side edges of the two precast members 1 are inserted into each other, and the side holes 11 are fitted together.

[0046] Refer to Figure 4 , construction workers pour an appropriate amount of concrete into the splicing seam between two adjacent precast members 1 to fill the splicing seam until the concrete slurry covers all the steel bars 121, and stop pouring. The reserved splicing seam is used to position the upper precast member 1, that is, when construction workers lay the upper precast member 1, the first side block 13 is inserted into the splicing seam corresponding to the lower precast member 1.

[0047] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
