Description

Technical Field

[0001] This application relates to the field of airport pavement laying technology, and particularly relates to an auxiliary device for pavement finishing. Background Art

[0002] According to the construction technical specifications of airport cement pavements, the construction technology of pavement concrete paving includes paving, vibrating, leveling, kneading, leveling, finishing, and grooving. When finishing the surface, it is necessary for workers to hold a trowel by hand and carefully smooth the surface of the layer that has been kneaded and leveled, press small stone sands into the board surface, and eliminate various uneven traces remaining on the board surface and sand holes.

[0003] In the related art, the newly poured pavement usually has a width of 5 meters. When finishing the surface at the edge of the pavement, due to the limited length of the arm and the insufficient length of the tool handle, it is impossible for workers to complete the pavement finishing work for the entire width. Therefore, workers need to step on the newly poured pavement with boots and then smooth the pavement bit by bit.

[0004] It is found in actual construction that during this process, workers need to slowly retreat on the pavement and then smooth the footprints they stepped on. The whole process is time-consuming and has low efficiency. Summary of the Invention

[0005] In order to improve the construction efficiency, this application provides an auxiliary device for pavement finishing, which is convenient for workers to smooth the pavement.

[0006] The auxiliary device for pavement finishing provided by this application adopts the following technical solution:

[0007] An auxiliary device for pavement finishing includes a support frame and a support board laid on the support frame. The support frame includes two cross beams erected on the templates on both sides of the pavement and multiple longitudinal beams connected between the two cross beams. The cross beams are arranged as upward-arching arched beams.

[0008] By adopting the above technical solution, a support frame is set and a support board is covered on the support frame. When in use, the two ends of the support frame are erected on the templates on both sides of the pavement, and then workers can step on the support board to smooth the pavement; the cross beams of the support frame are arranged as upward-arching arched beams. After the two ends of the cross beams are erected on the templates on both sides of the pavement, the upward-arching cross beams will not contact the pavement, which can prevent contact with the pavement; if the cross beams are arranged as straight beams, the downward bending of the cross beams may contact the pavement and damage the pavement. Arranging the cross beams as arched beams can prevent contact with the pavement.

[0009] Optionally, an arched reinforcing beam is fixedly installed at the positions on the support frame corresponding to the two cross beams respectively. The arched diameter of the reinforcing beam is smaller than the diameter of the cross beam. The reinforcing beam is located at the upper end of the cross beam, and both ends of the reinforcing beam are fixedly installed at both ends of the cross beam; A plurality of tie rods are fixedly installed between the cross beam on the same side and the reinforcing beam.

[0010] By adopting the above technical solution, an arched reinforcing beam is provided, and the reinforcing beam and the cross beam are connected by tie rods, which can effectively improve the overall structural strength, prevent the worker from stepping on it and causing downward bending deformation, and further help to improve the construction accuracy and construction efficiency.

[0011] Optionally, support blocks for supporting on the formwork are fixedly installed on the lower side of the support frame. There are two support blocks and they are respectively located at both ends of the support frame.

[0012] By adopting the above technical solution, support blocks are installed on the support frame. During use, the support blocks are placed on the formwork on both sides of the road surface, which can increase the height of the support frame on the road surface and prevent the support frame from contacting the road surface.

[0013] Optionally, sliding sleeves are fixedly installed at the positions on the support blocks corresponding to the cross beams. The sliding sleeves are slidably sleeved on the outer sides of the cross beams.

[0014] By adopting the above technical solution, sliding sleeves are installed at the positions on the support blocks corresponding to the cross beams. When dealing with road surfaces of different widths, the positions of the support blocks can be adjusted by sliding the sliding sleeves, which is convenient for use.

[0015] Optionally, locking bolts for tightly abutting against the side walls of the cross beams are screwed on the side walls of the sliding sleeves.

[0016] By adopting the above technical solution, after the support block is adjusted in place, the position of the support block can be fixed by tightening the locking bolts to tightly abut against the side walls of the cross beam.

[0017] Optionally, lifting handles are installed at both ends of the support frame.

[0018] By adopting the above technical solution, it is convenient for workers to carry and use.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

[0020] 1. By setting up a support frame and covering a support plate on the support frame, during use, the two ends of the support frame are placed on the templates on both sides of the road surface. Then, workers can step on the support plate to level the road surface. The cross beam of the support frame is set as an upward-arching arched beam. After the two ends of the cross beam are placed on the templates on both sides of the road surface, the upward arching of the cross beam will not contact the road surface, which can prevent contact with the road surface. If the cross beam is set as a straight beam, the downward bending of the cross beam may contact the road surface and damage the road surface. Setting the cross beam as an arched beam can prevent contact with the road surface;

[0021] 2. By setting up an arched strengthening beam and connecting the strengthening beam and the cross beam through a tie rod, the overall structural strength can be effectively improved, preventing the downward bending deformation when workers step on it, and thus helping to improve the construction accuracy and construction efficiency;

[0022] 3. By setting up support blocks on the support frame, during use, the support blocks are placed on the templates on both sides of the road surface, which can increase the height of the support frame on the road surface and prevent the support frame from contacting the road surface. When dealing with road surfaces of different widths, the position of the support block can be adjusted by moving the sliding sleeve, and then locked and fixed through the locking bolt, which is convenient to use.
