Description

Technical Field

[0001] The utility model belongs to the technical field of road construction jointing, and in particular relates to a transverse jointing device for non-grade roads. Background Art

[0002] After the road concrete is poured, the road needs to be split. The traditional operation is to use a seam cutter to cut the concrete after the concrete strength reaches 2.5Mpa through maintenance, and then pour the split material to form a shrinkage joint on the road. The whole process has relatively many steps, which wastes the construction period. In addition, the construction length is too long when the road is paved, and the time after the final setting of the concrete is relatively concentrated. The horizontal cutting requires a large number of personnel and equipment, and the construction is concentrated, which will also cause a lot of labor waste. For some non-grade roads with a width of 3.5 meters to 4 meters, the split plate can be directly inserted when the joint is processed. The construction time of this method is after the initial setting of the concrete. Previously, prefabricated split plates were inserted into concrete slurry, and after the concrete solidified, it naturally formed shrinkage joints in the road in cooperation with the split plates. This splitting process is simple, and the labor and working time consumption is relatively low. However, its shrinkage joint morphology is slightly worse than that formed by the traditional splitting method, and is suitable for use on non-grade roads. This method requires the use of a splitting device to complete the process of inserting the split plates into the mud. The existing splitting device has a relatively complex structure and is inconvenient to operate. It cannot fully exert its function for narrow roads and will also delay working hours. Therefore, it is very in line with practical needs to develop a simple and easy-to-use transverse splitting device for use on narrow non-grade roads. Utility Model Content

The rotating shaft 2 is inserted into the angle steel 1, and the rotating shaft 2 is rotatably connected to the angle steel 1. Both ends of the rotating shaft 2 extend out of the two ends of the angle steel 1, and a wrench 5 is provided on the outer circumferential surface of each end of the rotating shaft 2, and the bottom end of each wrench 5 is fixedly connected to the rotating shaft 2. The splint group is arranged in the angle steel 1, and the splint group is arranged opposite to the vertical plate part in the angle steel 1, and the top of the splint group is fixedly connected to the outer circumferential surface of the rotating shaft 2.

[0022] The transverse joint device for non-grade highways provided in the present embodiment is designed to realize the clamping action of the joint plate by driving the clamping plate to swing through the wrench. As the construction personnel keep pushing the wrench, the clamping force of the joint plate can be stably output.

[0024] Specific implementation method 2: Combination Figures 1 to 5 This embodiment is described. The difference between this embodiment and the first embodiment is that the clamping plate group includes a plurality of clamping plates 3, and the plurality of clamping plates 3 are arranged equidistantly in sequence along the length extension direction of the angle steel 1. The spacing dimension between two adjacent clamping plates 3 is L, and the value range of L is 0.8m to 1m. Other components and connection methods are the same as those of the first embodiment.

[0025] Such arrangement takes into account the clamping stability of the split plate. Since the length of the split plate is the same as the width of the road surface when the split plate is arranged, the device provided in this application is 3.5m to 4m, and a clamping plate 3 is arranged every 0.8m to 1m, which is beneficial to ensure the uniformity of clamping the split plate and avoid deformation of the split plate during clamping.

[0026] Specific implementation method three: Combination Figures 1 to 5 The present embodiment is described, and the difference between the present embodiment and the second embodiment is that the angle between the wrench 5 and the clamping plate set is a, and the value range of a is 130° to 160°. The other components and connection methods are the same as those of the second embodiment.

[0027] Such arrangement is conducive to improving the comfort of the construction workers when operating the wrench 5.

[0028] Specific implementation method four: Combination Figures 1 to 5 This embodiment is described. The difference between this embodiment and the third embodiment is that the handle 4 includes a longitudinal connecting rod 41 and a horizontal pull rod 42. The longitudinal connecting rod 41 is arranged at the top of the horizontal part of the angle steel 1 in the vertical direction, and the bottom end of the longitudinal connecting rod 41 is fixedly connected to the angle steel 1. The horizontal pull rod 42 is arranged at the top of the longitudinal connecting rod 41 in the horizontal direction, and the top end of the longitudinal connecting rod 41 is fixedly connected to the center of the bottom of the horizontal pull rod 42. Other components and connection methods are the same as those of the third embodiment.

[0029] In this embodiment, the longitudinal connecting rod 41 is a component used for holding during the lowering process, so as to facilitate the adjustment of the lowering trajectory of the slit device, and the horizontal pull rod 42 is a component used during the pulling process, so as to facilitate the operator to perform the pulling action;

[0030] In order to improve the versatility of the device so that it can meet the operating habits of most people, the longitudinal connecting rod 41 and the horizontal pull rod 42 are both split combination structures, and the longitudinal connecting rod 41 includes a plurality of connecting rod segments. The bottom of the connecting rod segment located at the bottom of the plurality of connecting rod segments is fixedly connected to the horizontal part in the angle steel 1, and a threaded hole is processed at the top of the bottom connecting rod segment, and a connecting threaded segment is provided at one end of the remaining connecting rod segments, and a connecting threaded hole is processed at the other end. The plurality of connecting rod segments are arranged in sequence along the length extension direction of the longitudinal connecting rod 41, and the two adjacent connecting rod segments are connected by threaded disassembly, and the bottom of the connecting rod segment located at the top is provided with a connecting threaded segment, and the top of the connecting rod segment at the top is fixedly connected to the bottom center of the horizontal pull rod 42. Construction personnel can adjust the number of connecting rod segments according to their own height and operating habits so that the total length of the handle 4 can be adjusted as needed.

[0031] Specific implementation method five: Combination Figures 1 to 5 This embodiment is described. The difference between this embodiment and the fourth embodiment is that a plurality of perforated steel blocks 11 are arranged at equal intervals at the bottom of the horizontal portion of the angle steel 1 along the length extension direction of the angle steel 1, each perforated steel block 11 is fixedly connected to the angle steel 1, and the rotating shaft 2 is inserted into the plurality of perforated steel blocks 11, and the rotating shaft 2 is rotatably connected to the plurality of perforated steel blocks 11. The other components and connection methods are the same as those of the fourth embodiment.

[0032] In this way, the rotating shaft 2 is supported by the perforated steel block 11. In order to improve the rotation stability of the rotating shaft 2 and prevent the rotating shaft 2 from axial movement during rotation, a bearing can be added in the hole for support. The bearing is arranged between the rotating shaft 2 and the perforated steel block 11, and the outer ring of the bearing is fixedly connected to the inner wall of the perforated steel block 11, and the inner ring of the bearing is fixedly connected to the rotating shaft 2.

[0033] Specific implementation method six: Combination Figures 1 to 5 This embodiment is described. The difference between this embodiment and the fifth embodiment is that the distance between the perforated steel block 11 and the inner top corner of the angle steel 1 is b, and the value range of b is 0.4 cm to 0.6 cm. The other components and connection methods are the same as those of the fifth embodiment.

[0034] With such arrangement, the distance between the perforated steel block 11 and the inner top corner of the angle steel 1 is equal to the thickness of the split plate to be clamped, ensuring that when the clamping plate 3 is in a vertical state, the gap between the vertical portion of the angle steel 1 is just enough to insert a split plate.

[0035] Specific implementation method seven: Combination Figures 1 to 5 This embodiment is described. The difference between this embodiment and the sixth embodiment is that the clamping side of the clamping plate 3 is processed with a grid pattern, the clamping side of the middle plate portion of the angle steel 1 is processed with a grid pattern, and the wrench 5 is arranged near the end of the angle steel 1. The other components and connection methods are the same as those of the sixth embodiment.

[0036] In this way, the grid pattern is used to increase the friction between the clamping plate 3 and the angle steel 1 and the split plate to ensure the stability of the clamping. The wrench 5 is close to the end of the angle steel 1 and does not contact the angle steel 1. The working distance between the wrench 5 and the handle 4 can be shortened, which makes it convenient for construction workers to control the handle and the wrench with both hands at the same time. The gap between the wrench 5 and the angle steel 1 is to reduce the friction between the wrench 5 and the angle steel 1 to ensure the smoothness of the operation of the wrench 5.

[0037] The present invention has been disclosed as above with preferred implementation cases, but it is not used to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent implementation cases with equivalent changes by using the above-disclosed structures and technical contents without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above implementation cases based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.

[0038] How it works

[0039] When the present application is used, it is first necessary to mark the arrangement position of the split plate 6 on both sides of the poured road surface according to the design data, so as to facilitate the subsequent insertion of the split plate, assemble the various components according to the connection relationship described in specific implementation methods one to seven, and use a long board to lay on the poured road surface. The long board should be set close to the arrangement position of the split plate 6, and the two ends of the long board are overlapped on both sides of the road surface. After the construction personnel climb onto the long board, they transport the prefabricated split plate 6 to the long board and keep the split plate 6 in an upright state, set the split plate 6 in the angle steel 1 and make one side of the split plate 6 fit with the vertical plate part of the angle steel 1. At this time, push the wrench 4 to make the clamping plate 3 swing close to the split plate 6 until the clamping plate 3 contacts with the split plate 6, and the construction personnel keep pushing the wrench 5 to provide continuous clamping force to the split plate 6. It is worth noting that the present application requires the cooperation of two construction personnel when in use, and each construction personnel controls a handle 4 and an adjacent wrench 5. Under the premise that the two construction personnel can ensure the clamping reliability, the lower part of the split device holding the split plate 6 is inserted into the concrete slurry, and after the split plate 6 is completely immersed in the slurry, the wrench 4 is pulled at the same time to separate the clamp plate 3 from the split plate 6. At this time, the split device and the split plate are in a relaxed state, and the construction personnel pull the handle 4 upward to pull the split device out of the concrete slurry to complete the installation of a split plate 6.
