Description

Technical Field

[0001] The present application relates to the field of road construction technology, and in particular to a quick-release mold for laying a water-stabilizing layer on a road. Background Art

[0002] The laying of a water-stabilizing layer is an essential part of road construction, especially in highway construction. The water-stabilizing layer serves as the bottom foundation layer of the road, and is paved with cement and gravel to enhance the stability of the road.

[0003] During the construction process, the paving of the water-stable layer first requires the use of crushed stone as aggregate. Cementitious materials and materials are then used to fill and spread the gaps between the aggregates. Then, construction workers drive multiple road rollers, which move simultaneously and parallel to the road, to compact the water-stable layer. During the compaction process, because the crushed stone accumulates to a certain height, it is necessary to set up vertical limiting molds on both sides of the road to withstand the horizontal pushing force of the stones during the compaction of the water-stable layer, confining the crushed stone within the width of the road and preventing the water-stable layer from collapsing.

[0004] Existing restriction molds are simply laid on both sides of the road. Before gravel processing, construction workers place the restriction molds at preset positions on both sides of the road, and can remove them after compaction and concrete slurry solidification. However, a single road construction section is long, and the method of manually dismantling the molds one by one by construction workers is obviously labor-intensive and inefficient. Summary of the Invention

[0005] In order to improve the efficiency of laying water-stabilizing layers in road construction and reduce the labor intensity of workers, the present application provides a quick-release mold for laying water-stabilizing layers in roads.

[0006] The present application provides a quick-release mold for paving a road water-stabilizing layer, which adopts the following technical solutions:

[0007] A quick-release mold for paving a road water-stabilizing layer, comprising:

[0008] A quick-release plate, with hinge structures at both ends for connecting multiple quick-release plates;

[0009] A support rod is horizontally slidably connected to one side of the quick release plate, one end of the support rod is hinged to the quick release plate, and a fixing piece for fixing the support rod is provided on the quick release plate;

[0010] The plug-in rods are formed on a length side edge of the quick release plate, are distributed at equal intervals along the length direction of the quick release plate, and are arranged parallel to the plate surface of the quick release plate.

[0011] By adopting the above technical solution, the quick-release plate is a rectangular plate. When in use, the construction workers place the quick-release plate on both sides of the construction area of the road water-stabilizing layer. The plate surface of the quick-release plate restricts the stones inside the water-stabilizing layer. Under the huge pressure, the stones are horizontally pressed to both sides.

[0012] In order to improve the stability of the quick-release plate, a plug-in rod is provided on one length side or bottom side of the quick-release plate. When the quick-release plate is vertically installed on both sides of the road surface, the quick-release plate is inserted into the roadbed soil to stabilize the distribution of the quick-release plate.

[0013] After the quick-release plate is installed, the support rod rotates around the hinge point to be perpendicular to the surface of the quick-release plate, and slides to the preset position so that the other end of the support rod touches the ground to complete the support. Therefore, in actual application, the support rod can be tilted to the surface of the plate by selecting a ball hinge to improve the flexibility of the support rod.

[0014] Optionally, the quick-release plate is provided with a support rod groove horizontally corresponding to the support rod, and the length of the support rod groove is greater than the length of the support rod.

[0015] By adopting the above technical solution, the support rod groove is used to accommodate the support rod in a horizontal state. When the road construction is completed, the support rod is horizontally rotated into the support rod groove to complete the storage of the support rod.

[0016] Optionally, the fixing member includes a fixing rod formed on one end of the support rod slot and on the surface of the quick release plate. The fixing rod is arranged parallel to the surface of the quick release plate, and its length is greater than the height of the support rod slot.

[0017] By adopting the above technical solution, since the length of the above-mentioned support rod groove is greater than the length of the support rod, when the support rod is received in the support rod groove, a gap is provided between the end of the support rod groove and the end of the support rod, and the fixing rod is provided between one end of the support rod groove and the corresponding end of the support rod, so that the support rod slides toward the direction of the fixing rod and engages, thereby limiting the rotation of the support rod and stably receiving the support rod in the support rod groove.

[0018] Optionally, a slider is slidably connected in the support rod groove, a ball groove is provided in the slider, a metal ball is installed in the ball groove, and the metal ball is fixedly connected to one end of the support rod; a through groove is horizontally provided on the slider, and the through groove connects the support rod groove and the ball groove.

[0019] By adopting the above technical solution, the slider serves as the connecting structure between the support rod groove and the quick-release plate. A ball groove is opened inside the slider, and a metal ball is movably connected in the ball groove. The metal ball can rotate freely in the ball groove, but is restricted by the ball groove and can only move in the ball groove. The metal ball in the ball groove is connected to the support rod, and a corresponding through groove is opened to realize the connection between the metal ball in the ball groove and the support rod. The rotation of the support rod is restricted by the through groove.

[0020] Optionally, two of the sliding blocks and the support rods are provided in the support rod groove.

[0021] By adopting the above technical solution, the stress is greater at the road bends, and there is a certain angle between adjacent quick-release plates. When the water-stabilizing layer in this part is compacted, the horizontal stress is concentrated. Therefore, the two rods can play a supporting role at both ends of the quick-release plate to enhance the stability of the quick-release plate.

[0022] Optionally, a plugging hole adapted for the plugging rod is formed on an edge of one side of the quick-release plate facing away from the plugging rod, and the plugging holes correspond one-to-one to the plugging rods.

[0023] By adopting the above technical solution, when the construction environment is special, such as mountainous areas, national highways, etc. where high roadbed strength requirements are required, a thicker water-stabilizing layer is required. Therefore, the height of a single-layer quick-release plate is insufficient, and an additional layer of quick-release plate is required. Therefore, a plug-in hole is formed under the upper quick-release plate, and the plug-in rod is inserted into the plug-in hole to stabilize the connection of the vertically upward quick-release plate.

[0024] Optionally, the plug hole is parallel to the plate surface of the quick release plate and passes through the quick release plate.

[0025] By adopting the above technical solution, the insertion hole can be penetrated to allow a metal rod to be inserted into the insertion hole. After the quick-release plate is installed, the metal rod is vertically inserted through the insertion hole, and one end of the metal rod is inserted into the soil.

[0026] In the above solution, the plug holes and plug rods on both sides of the quick release plate need to be distributed crosswise to avoid structural interference.

[0027] Optionally, the hinge structure includes:

[0028] A hinge plate is arranged parallel to the surface of the quick release plate, one edge of the hinge plate is hinged to one side of an end surface of the quick release plate, and a hinge cylinder is formed on the hinge plate away from the hinge side;

[0029] The hinge shaft is fixedly connected to one end of the quick-release plate away from the hinge plate and is adapted to be arranged on the hinge cylinder.

[0030] By adopting the above technical solution, the hinged relationship between the hinge plate and the hinge axis is the connection structure of the quick-release plate at the edge of the same side of the road. In order to adapt to the turning part of the road, the quick-release plates are at a certain angle. The hinge plate plays a role in sealing and strengthening the connection between the two adjacent quick-release plates.

[0031] If the hinged plate is not installed, when the stones in the water-stabilizing layer expand horizontally under pressure, the part between the two quick-release plates at a certain angle will be unstable. Therefore, the hinged plate can not only improve the flexibility between the two quick-release plates, but also improve the strength of the connection structure between the two quick-release plates.

[0035] The following is combined with Figure 1-2 This application is described in further detail.

[0036] The embodiment of the present application discloses a quick-release mold for laying a road water-stabilizing layer. Figure 1 A quick-release mold for paving a water-stabilizing layer of a road includes a quick-release plate 1, which is the main structure of the quick-release mold. Connection structures are provided on both side edges and both ends of the quick-release plate 1 in the length direction for connecting the quick-release plates 1.

[0037] Reference Figure 1 A plurality of plug-in rods 11 are formed on a longitudinal side edge of the quick-release plate 1, or more specifically, on the bottom side edge during construction. The plurality of plug-in rods 11 are cylindrical, with their axes parallel to the longitudinal direction of the quick-release plate 1. The plurality of plug-in rods 11 are evenly spaced along the longitudinal direction of the quick-release plate 1. A plug-in hole 12 is formed inside the quick-release plate 1, parallel to the plug-in rod 11. The diameter of the plug-in hole 12 matches the diameter of the plug-in rod 11, allowing the plug-in rod 11 to be plugged into the plug-in hole 12. In this embodiment, the plug-in hole 12 is formed through the quick-release plate 1. The plug-in holes 12 are distributed alternately with the plug-in rod 11 on the same side of the quick-release plate 1 as the plug-in rod 11, avoiding structural interference between the plug-in rod 11 and the plug-in hole 12. As a result, during construction, construction workers can plug the plug-in rod 11 of a quick-release plate 1 into the plug-in hole 12, and can also insert a metal rod of corresponding size from the plug-in hole 12 into the roadbed soil, thereby stabilizing the installation of the quick-release plate 1 on both sides of the road.

[0038] Reference Figure 1One end of the quick release plate 1 is fixedly connected to a hinge shaft 13, the axial direction of the hinge shaft 13 is parallel to the plate surface of the quick release plate 1 and perpendicular to the length direction of the quick release plate 1, and a side edge of the other end of the quick release plate 1 is hinged with a hinge plate 15, the plate surface of the hinge plate 15 is parallel to the plate surface of the quick release plate 1, and the hinge plate 15 rotates around the hinge side until its plate surface forms a certain angle with the plate surface of the quick release plate 1, the height of the hinge plate 15 is the same as the height of the quick release plate 1, and the length of the hinge plate 15 is the same as the width of the quick release plate 1. Therefore, the hinge plate 15 can rotate around the hinge side to fit the end of the quick release plate 1 to accommodate the hinge plate 15, and can also rotate around the hinge side to form any flexible angle with the plate surface of the quick release plate 1. A hinge tube 14 is formed on the side of the hinge plate 15 facing away from the quick-release plate 1. The hinge tube 14 is arranged parallel to the hinge shaft 13. The inner diameter of the hinge tube 14 is adapted to the diameter of the hinge shaft 13. The hinge shaft 13 is inserted into the hinge tube 14 to complete the insertion of the two quick-release plates 1. At the same time, the hinge plate 15 is rotated to adjust the angle between the two quick-release plates 1.

[0039] Reference Figure 1 and Figure 2 The two sliders 21 are slidably connected in the support rod groove 2, and the two sliders 21 slide along the length direction of the quick release plate 1. The two sliders 21 are slidably arranged at different depths of the support rod groove 2, and the two sliders 21 are arranged at two different ends of the support rod groove 2, taking one of the sliders 21 as an example; a ball groove is provided inside the slider 21, and a metal ball 22 is placed in the ball groove. A through groove 24 is provided on the side wall of the slider 21, and the through groove 24 connects the ball groove inside the slider 21 with the support rod groove 2 outside the slider 21. A support rod 23 parallel to the length direction of the quick release plate 1 is provided in the support rod groove 2 corresponding to each slider 21. The length of the support rod 23 is adapted to the width of the through groove 24, so that one end of the support rod 23 passes through the through groove 24 and is fixed to the metal groove (generally welding is selected), and through the through groove 24, the support rod 23 can be flexibly rotated along the opening direction of the through groove 24, so that the support rod 23 extends out of the support rod groove 2. The through slot 24 extends perpendicularly to the length direction of the quick release plate 1 from the center of the slider 21 , so that the support rod 23 can tilt along the slot and form a certain tilt angle with respect to the surface of the quick release plate 1 .

[0040] Reference Figure 1 The quick-release plate 1 is located at one end of the support rod groove 2. To be more precise, a fixing rod 25 is fixed to the end of the support rod groove 2 away from the outer slider 21 of the two sliders 21. The fixing rod 25 is used to limit the support rod 23. The length of the support rod groove 2 is greater than the length of the support rod 23. When the slider 21 is located at one end of the support rod groove 2, the fixing rod 25 is located between the free end of the support rod 23 and the end of the support rod groove 2, and cannot limit the support rod 23.

[0041] The implementation principle of a quick-release mold for paving a water-stabilizing layer of a road in an embodiment of the present application is as follows: in the initial state, the support rod 23 is received in the support rod groove 2 and is restricted by the support rod 23. When in use, the construction personnel slide the slider 21 to one end so that the fixed rod 25 cannot restrict the support rod 23, and rotate the support rod 23 to tilt the support rod 23. After the quick-release plate 1 is placed, the support rod 23 abuts against the ground to play a supporting role. At the same time, check whether the plug-in rod 11 is stably connected to the soil. If the soil is loose, the construction personnel can also choose to insert a metal rod into the plug-in hole 12, and the metal rod is inserted into the ground to strengthen the connection.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
