Description

Technical Field

[0001] This utility model relates to the field of road paving, and in particular to an auxiliary device for road stone surface paving. Background Technology

[0002] In municipal, landscaping, and scenic road construction, natural stone or artificial stone slabs are widely used as surface paving materials due to their aesthetic appeal and durability. However, traditional stone slab paving techniques present significant technical challenges: it is difficult to efficiently and accurately ensure the flatness and alignment of adjacent slabs and the uniformity of gaps. Currently, construction mainly relies on manually setting up baselines combined with visual inspection and experience for positioning. This method has many drawbacks: First, the baselines are mostly single lines, controlling only one direction (such as longitudinal or transverse), making it difficult to simultaneously and accurately constrain the position of the stone slab in two dimensions within the plane; second, the set baselines are easily displaced or loosened by construction disturbances (such as people stepping on them or tools colliding), leading to reference failure; third, relying entirely on workers' experience to judge the distance between the stone slab edges and the baseline, as well as the height difference between adjacent slabs, results in high labor intensity, low efficiency, and difficulty in ensuring the overall flatness and gap consistency of large-area paving. Especially when encountering irregularly shaped stone slabs or complex paving patterns, problems such as misalignment and unevenness become more prominent, seriously affecting the project quality and aesthetic effect. Therefore, there is an urgent need for an auxiliary device that can effectively, reliably, and conveniently constrain the position of stone slabs in two dimensions, significantly improving paving accuracy and efficiency, in order to solve the core problem of difficulty in aligning stone slabs in existing technologies.

[0023] Please see Figures 1 to 12 As shown, the auxiliary device for road stone surface paving includes a splicing frame 1, several lateral limiting units 2 and several longitudinal limiting units 3. The several lateral limiting units 2 are evenly distributed longitudinally on the splicing frame 1, and the several longitudinal limiting units 3 are evenly distributed laterally on the splicing frame 1. The several lateral limiting units 2 and several longitudinal limiting units 3 are staggered vertically. The positions of the lateral limiting units 2 and the longitudinal limiting units 3 on the splicing frame 1 are adjustable. The lateral limiting units 2 and the longitudinal limiting units 3 have the same structure.

[0024] Specifically, the splicing frame 1 is placed on the base surface where the stone slabs are to be laid. Then, the spacing between the horizontal limiting units 2 and the spacing between the vertical limiting units 3 are adjusted according to the length and width of the stone slabs to be laid. After adjustment, the horizontal limiting units 2 and the vertical limiting units 3 are fixed. Then, the stone slabs are laid according to the grid formed by the horizontal limiting units 2 and the vertical limiting units 3.

[0025] The lateral limiting unit 2 includes a steel wire rope 21 and a steel wire rope tensioning and fixing device 22. The steel wire rope tensioning and fixing device 22 is disposed at both ends of the steel wire rope 21, and the steel wire rope 21 is disposed on the splicing frame 1 through the steel wire rope tensioning and fixing device 22.

[0026] Specifically, the lateral limiting unit 2 and the longitudinal limiting unit 3 are respectively set on the splicing frame 1 by corresponding wire rope tensioning and fixing devices. The wire rope tensioning and fixing devices can tension and fix the wire ropes.

[0027] The splicing frame 1 includes a longitudinal frame 11, a transverse frame 12, auxiliary reinforcing screws 13, auxiliary tightening nuts 14, mounting blocks 15, and mounting bolts 16. Several first slots 121 are evenly arranged on the transverse frame 12, and threaded holes 122 are provided in the corresponding first slots 121. First sliding grooves 123 are provided on the side walls of the transverse frame 12. Transverse frame mounting grooves 111 are provided at both the front and rear ends of the longitudinal frame 11. Second slots 112 are provided at the top of the transverse frame mounting grooves 111. Second sliding grooves 113 are provided on the side walls of the longitudinal frame 11. A through hole 115 is provided at the front end of the longitudinal frame 11. The transverse frame... The frame 12 is slidably set in the transverse frame mounting groove 111. The first slot 121 on the transverse frame 12 and the second slot 112 on the longitudinal frame 11 are used together. When the first slot 121 and the second slot 112 are aligned, the mounting block 15 can be simultaneously inserted into the first slot 121 and the second slot 112. The front end of the mounting bolt 16 can pass through the mounting block 15 and be screwed into the threaded hole 122. The auxiliary reinforcing screw 13 can pass through the through hole 115 at the front end of the longitudinal frame 11. There are four auxiliary tightening nuts 14. The auxiliary tightening nuts 14 are screwed onto the auxiliary reinforcing screw 13 and distributed on both sides of the longitudinal frame 11.

[0028] Specifically, the longitudinal frames 11 are arranged symmetrically from left to right, and the transverse frames 12 are simultaneously mounted on the two longitudinal frames 11 via transverse frame mounting slots 111. There is one transverse frame 12 at the front and back of each of the two longitudinal frames 11. At this time, the transverse frames 12 and the longitudinal frames 11 can slide freely. We can adjust the area enclosed by the longitudinal frames 11 and the transverse frames 12 according to the space to be constructed. When adjusted to the required size, the first slot 121 on the transverse frame 12 that is closest to the second slot 112 is then aligned with the second slot 112. Align the components, then snap the mounting block 15 into the first slot 121 and the second slot 112. Then, screw the mounting bolt 16 through the mounting block 15 into the corresponding threaded hole 122. At this time, the transverse frame 12 and the longitudinal frame 11 are locked and limited by the mounting block 15. Repeat the above operation for the other three contact points. Finally, the transverse frame 12 and the longitudinal frame 11 are completely locked. Then, the auxiliary reinforcing screw 13 passes through the through hole 115 between the two longitudinal frames 11. Finally, tighten the auxiliary tightening nut 14 to reinforce the entire frame.

[0029] The wire rope tensioning and fixing device 22 includes a fixing member 221, a tensioning member 222, a fixing member locking nut 223, a washer 224, a tensioning member locking nut 225, and a wire rope locking stud 226. The fixing member 221 is slidably disposed on the first slide groove 123 and the second slide groove 113. The front end of the fixing member 221 is provided with an external thread. The fixing member locking nut 223 is screwed to the front end of the fixing member 221 through the external thread. A washer 224 is provided between the fixing member locking nut 223 and the fixing member 221. The fixing member 221 is provided with an internal thread, and the tensioning member 222 is provided with an external thread. The tensioning member 222 is screwed inside the fixing member 221. A part of the tensioning member 222 extends out of the inside and outside of the fixing member 221. A tensioning member locking nut 225 is screwed onto the tensioning member 222. The tensioning member 222 has a through hole for the wire rope to pass through. A wire rope locking stud 226 is provided at the rear end of the tensioning member 222. The wire rope locking stud 226 is screwed to the rear end of the tensioning member 222. The front end of the wire rope locking stud 226 can pass through the through hole inside the tensioning member 222 to squeeze the wire rope passing through the through hole. The tail of the tensioning member 222 is also provided with an external hexagonal protrusion 2221 for cooperating with a wrench.

[0030] Specifically, the fixing member 221 is slidably disposed on the first slide groove 123 and the second slide groove 113. The front end of the fixing member 221 is provided with an external thread, and the fixing member locking nut 223 is screwed onto the front end of the fixing member 221 through the external thread. A washer 224 is provided between the fixing member locking nut 223 and the fixing member 221. When it is necessary to adjust the fixing member 221, the fixing member locking nut 223 is loosened. At this time, the washer 224 is far from the sidewalls of the first slide groove 123 and the second slide groove 113. When the fastener 221 is adjusted to the desired position, tighten the fastener locking nut 223. The fastener locking nut 223 presses the pad 224 tightly against the sidewalls of the first slide groove 123 and the second slide groove 113. At this time, the fastener 221 cannot move freely and is locked. When it is necessary to adjust the tension of the wire rope, first loosen the wire rope locking stud 226. At this point, the wire rope can slide freely within the tensioning member 222 and the fixing member 221. Then, the wire rope locking stud 226 of the wire rope tensioning and fixing device 22 at one end is tightened, and this section of the wire rope is fixed. Then, the worker uses pliers or other tools to pull the wire rope in the tensioning and fixing device 22 at the other end to pre-tighten the wire rope. Then, the wire rope locking stud 226 of the wire rope tensioning and fixing device 22 at this end is tightened, and the wire ropes at both ends are fixed. Tighten the tensioning member 222, and then use a wrench to rotate the tensioning member 222 through the external hexagonal protrusion 2221 at the tail of the tensioning member 222, so that it moves away from the fixing member 221. The tensioning member 222 drives the end of the wire rope to move away from the fixing member 221, thereby achieving the purpose of tightening the wire rope. When the wire rope reaches the required tension, tighten the locking nut 225 of the tensioning member until it is in close contact with the fixing member 221 to prevent the tensioning member 222 from reversing and causing the tension of the wire rope to change.

[0031] The bottom of the first slide groove 123 and the second slide groove 113 are respectively provided with a first scale line 124 and a second scale line 114. The bottom of the fixing member 221 is provided with an indicator groove 2211, which is used in conjunction with the first scale line 124 and the second scale line 114.

[0032] Specifically, in order to make the position of the wire rope more accurate, the bottom of the first slide groove 123 and the second slide groove 113 are respectively provided with the first scale line 124 and the second scale line 114. The bottom of the fixing member 221 is provided with the indicator groove 2211. During adjustment, the indicator groove 2211 corresponds to the first scale line 124 and the second scale line 114, thereby determining the position of the fixing member 221.

[0033] The working principle and process of this utility model:

[0034] In use, first adjust the area enclosed by the longitudinal frame 11 and the transverse frame 12 according to the space to be constructed. When the required size is reached, insert the mounting block 15 into the first slot 121 and the second slot 112. Then, screw the mounting bolt 16 through the mounting block 15 into the corresponding threaded hole 122. At this time, the transverse frame 12 and the longitudinal frame 11 are locked and limited by the mounting block 15. Repeat the above operation for the other three contact points. Finally, the transverse frame 12 and the longitudinal frame 11 are completely locked. Then, the auxiliary reinforcing screw 13 passes through the through hole 115 between the two longitudinal frames 11. Finally, tighten the auxiliary tightening nut 14 to reinforce the entire frame. Then, adjust the spacing between the transverse limiting units 2 and the spacing between the longitudinal limiting units 3 according to the length and width of the stone slab to be laid. After adjustment, fix the transverse limiting units 2 and the longitudinal limiting units 3. Then, lay the stone slab according to the grid formed by the transverse limiting units 2 and the longitudinal limiting units 3.
