Description

Technical Field

[0001] The utility model relates to the field of prefabricated road panels, in particular to a recycled concrete prefabricated road panel. Background Art

[0002] Recycled concrete refers to new concrete made by crushing, cleaning, and grading discarded concrete blocks, mixing them with grading in a certain proportion, partially or completely replacing natural aggregates such as sand and gravel (mainly coarse aggregates), and then adding cement, water, etc.

[0003] Prefabricated road panels are a new type of pavement material with the advantages of easy construction and long service life. For example, cement concrete road panels are mainly made of raw materials such as cement, aggregate, fly ash, etc. They have the characteristics of high strength, long service life and simple construction process.

[0004] Therefore, using recycled concrete to make prefabricated pavements can achieve waste utilization and reduce costs.

[0005] However, existing prefabricated road panels are simply recycled concrete prefabricated into a plate-like structure. For temporary construction that requires rapid pavement laying and later dismantling and recycling, the use of conventional prefabricated road panels will increase the construction period and difficulty.

[0006] Although the Chinese invention patent application with application number 202210113019.1 provides a prefabricated slab structure for mine pavement paving, and the connection between adjacent concrete slabs is achieved by arranging adjacent rectangular steels outside the concrete slabs, this connection method is too cumbersome and has the disadvantage of high alignment difficulty, and cannot effectively improve construction efficiency. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present utility model.

[0028] like Figure 1-5 As shown, the utility model provides a recycled concrete prefabricated road panel, including a recycled concrete panel 1 prefabricated from recycled concrete, which has low cost and is more environmentally friendly.

[0029] A plug rod 6 is pre-embedded at one end of the recycled concrete panel 1, and a slot 2 is preset at the opposite end of the recycled concrete panel 1, wherein the slot 2 is directly opposite to the plug rod 6 and the inner diameter of the slot 2 matches the outer diameter of the plug rod 6, so that two adjacent recycled concrete panels 1 can be spliced ​​together by cooperating between the plug rod 6 of one recycled concrete panel 1 and the slot 2 of the other recycled concrete panel 1.

[0030] In order to make the recycled concrete panel 1 meet the strength requirement, transverse reinforcing ribs 13 and longitudinal reinforcing ribs 14 are pre-embedded inside the recycled concrete panel 1 .

[0031] In order to facilitate the transportation and laying of the recycled concrete panel 1, a pull ring 12 is provided on the recycled concrete panel 1. The pull ring 12 is detachably connected to the recycled concrete panel 1, so that the pull ring 12 can be removed after the laying is completed, thereby improving the construction efficiency without affecting the use of the road surface and meeting the actual construction needs.

[0032] The pull ring 12 can be optionally threadedly connected to the recycled concrete panel 1 through the threaded rod 11 .

[0033] Preferably, a rectangular groove 8 is opened inside the recycled concrete panel 1, a limit plate 9 is arranged in the rectangular groove 8, a lifting hole is opened on the recycled concrete panel 1, a threaded sleeve 10 is arranged in the lifting hole, and when in use, the pull ring 12 is screwed to the limit plate 9 through the threaded rod 11 to avoid unstable connection between the threaded rod 11 and the threaded sleeve 10, and the limit plate 9 is used for secondary limiting to ensure safe and reliable lifting and transportation.

[0034] Specifically, the number of the insertion rods 6 on the recycled concrete panel 1 can be set to multiple. Taking four as an example, the four insertion rods 6 are arranged at intervals along the end surface of the recycled concrete panel 1, and the corresponding number of slots 2 also needs to be set to four, so that the four slots 2 and the four insertion rods 6 on the recycled concrete panel 1 spliced ​​therewith can cooperate to achieve a stable and reliable connection between two adjacent recycled concrete panels 1.

[0035] In order to further improve the stability and reliability of the connection between two adjacent recycled concrete panels 1 after assembly, a fixing groove 7 is selected to be opened on the insertion rod 6, and a socket 22 is opened on the recycled concrete panel 1. The socket 22 is connected to the slot 2, and a first threaded groove 4 is set on the inner wall of the socket 22. The number of the sockets 22 is the same as the number of the slots 2.

[0036] Therefore, in actual use, after the insertion rod 6 is plugged into the slot 2, the fixing bolt 5 is selected to be screwed with the first thread groove 4, so that the fixing bolt 5 passes through the first thread groove 4 and then through the fixing groove 7, thereby matching the insertion rod 6 with the slot 2.

[0037] Preferably, a positioning groove 3 is opened at the bottom of the slot 2 so that the fixing bolt 5 can be screwed into the positioning groove 3, thereby further improving the stability and reliability of the fit between the fixing bolt 5 and the insertion rod 6 and the slot 2, ensuring that the paved road surface meets the use requirements.

[0038] Further explanation, in order to further improve the connection stability of the recycled concrete panel 1, a connecting groove 15 is selected to be opened at one end of the recycled concrete panel 1, and a connecting plate 17 is selected to be set at the other end of the recycled concrete panel 1. The connecting groove 15 and the connecting plate 17 are opposite to each other so that two adjacent recycled concrete panels 1 can be connected to the connecting plate 17 through the connecting groove 15.

[0039] At this time, a second threaded groove 18 is provided on the connecting plate 17, and a locking seat 16 is provided on the connecting groove 15. When splicing the recycled concrete panels 1, the connecting plate 17 on one recycled concrete panel 1 is connected to the locking seat 16 on the connecting groove 15 on another recycled concrete panel 1 through the mounting bolts 19 to ensure stable and reliable assembly.

[0040] At the same time, an anti-skid layer is selected to be arranged on the outer side of the recycled concrete panel 1, and the anti-skid layer includes a first anti-skid strip 20 arranged on the top of the recycled concrete panel 1 and a second anti-skid strip 21 arranged on the bottom of the recycled concrete panel 1, so as to increase the anti-skid effect and paving stability of the paved road surface.

[0041] Working principle:

[0042] When the device is in use, the pull ring 12 is fixed in the threaded sleeve 10 through the threaded rod 11 by a lifting device such as a crane, and the recycled concrete panel 1 is lifted by the pull ring 12 for easy movement.

[0043] Arrange multiple recycled concrete panels 1 end to end, and then adjust the positions of the recycled concrete panels 1 so that two adjacent recycled concrete panels 1 are matched with each other through the insertion rod 6 and the slot 2, thereby completing the preliminary splicing between the two recycled concrete panels 1.

[0044] Then, the fixing bolt 5 is passed through the fixing groove 7 on the corresponding insertion rod 6 along the first thread groove 4 on the insertion hole 22, and the bottom of the fixing bolt 5 is screwed into the positioning groove 3 to achieve stable matching of the insertion rod 6 and the slot 2.

[0045] Subsequently, by installing the bolt 19 and rotating the second threaded groove 18 into the corresponding locking seat 16, the connecting groove 15 and the connecting plate 17 are fixed to each other, thereby performing secondary fixation on the recycled concrete panel 1, improving the connection strength of the panel, and completing the splicing.

[0046] Connect multiple panels according to actual construction conditions to provide a smooth construction surface.

[0047] When the project is completed, the fixing bolts 5 and the mounting bolts 19 are removed from the first thread groove 4 and the second thread groove 18, and the panels are separated by a hoisting device to complete the removal work.

[0048] Obviously, the embodiments described above are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
