Description

Technical Field

[0001] The utility model relates to the technical field of pavement base drainage, and more specifically, to a fixture for reinforcing the formwork of porous cement stabilized macadam on the road surface. Background Art

[0002] Porous cement stabilized macadam is widely used in projects such as roads, bridges, dams, docks, etc. It has excellent mechanical properties, crack resistance and durability, and is a stable material with excellent performance.

[0003] With the acceleration of the urbanization process, road construction has become an indispensable part of urban construction. The pavement base is an important part of road construction, and its basic functions of bearing the load of the road and realizing drainage are important guarantees for the safe use of the road.

[0004] During the construction of the pavement base, in order to drain the free water that penetrates through the pavement joints, cracks or voids, or infiltrates from the subgrade or shoulder and stays in the pavement structure, an edge drainage system can be set along the pavement edge, and a drainage base or a drainage cushion drainage system can be set in the pavement structure. At present, porous cement stabilized macadam has been widely used in road construction, and it has the characteristics of firmness, stability and good drainage performance.

[0005] During the construction of the pavement drainage system, it is necessary to set porous cement stabilized macadam and perforated PVC drain pipes at the pavement edge, and set transverse drain pipes at intervals of 25m to infiltrate and drain the free water on the road surface. During the construction of porous cement stabilized macadam, it is necessary to excavate trenches and install formworks on both sides along the longitudinal direction of the road.

[0006] At present, the formworks on both sides of the porous cement stabilized macadam are usually supported by wooden beams, and the top of the formwork is fixed by tying steel bars to the wooden beams on both sides of the formwork. However, due to the long single-operation line of the porous cement stabilized macadam, the conventional formwork fixing method is time-consuming and laborious, requires a large amount of labor and materials, and has low construction efficiency, which cannot meet the needs of rapid construction.

[0007] Therefore, how to provide a fixture that can quickly reinforce the formworks on both sides of the porous cement stabilized macadam, reduce labor consumption and improve operation efficiency is an urgent problem to be solved by those skilled in the art. Summary of the Utility Model

[0008] In view of this, the utility model provides a fixture for reinforcing the formwork of porous cement stabilized macadam on the road surface, aiming to solve the above technical problems.

[0009] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0010] A clamping device for reinforcing the formwork of porous cement stabilized macadam for road surface, which is clamped between the formworks on both sides of the porous cement stabilized macadam, includes:

[0011] A support plate,

[0015] Bolts, there are multiple bolts which are respectively rotatably connected to the panel surfaces of the first vertical plate and the second vertical plate, and the threaded ends of the bolts can abut against the side wall of the formwork opposite to them.

[0016] The beneficial effect of the above technical solution is that after the formwork is placed, it is clamped on the formworks on both sides through the first vertical rod and the clamping rod, the second vertical rod and the clamping rod, and the bolts are screwed so that the bolts abut against the side wall of the formwork. When constructing the porous cement stabilized macadam, the extrusion force of the macadam will not squeeze and deform the formwork, ensuring the stability of the formwork.

[0017] Preferably, nuts are fixed on the panel surfaces of the first vertical plate and the second vertical plate, and the axis of the bolt is arranged perpendicular to the side wall of the formwork and is screwed with the nut. The rotation of the bolt is realized through the nut. After installation, the clamping device and the formwork form an integral body through the bolt, which is convenient and simple to install, improves the construction efficiency of formwork reinforcement, and reduces the labor intensity of operators.

[0018] Preferably, it further includes a supporting plate, the supporting plate is vertically fixed at one end of the first vertical plate away from the support plate, and the panel surface of the supporting plate can abut against the road surface; one end face of the supporting plate and one side face of the first vertical plate close to the clamping plate are in the same horizontal plane. The supporting plate can be placed on the road surface to ensure the firm fixation of the clamping device.

[0019] Preferably, the length of the first vertical plate is less than the length of the second vertical plate, and the first vertical plate and one of the clamping plates are clamped on the formwork on the side close to the road surface; the second vertical plate and the other clamping plate are clamped on the formwork on the side close to the slope. It adapts to the characteristics of the slope section and effectively improves the reinforcement quality of the formwork.

[0020] Preferably, the panel surfaces of the support plate, the first vertical plate, the second vertical plate and the clamping plate are all arranged perpendicular to the road surface, and the panel surface of the supporting plate is arranged parallel to the road surface.

[0021] Preferably, the support plate, the first vertical plate, the second vertical plate and the clamping plate are all made of stainless steel plates with a thickness of not less than 2 cm. The fixture is made of stainless steel plates with a thickness of not less than 2 cm, which gives it a certain strength, is not easily deformed, improves the turnover efficiency and reduces the construction cost.

[0022] Preferably, the side of the clamping plate away from the formwork is an inclined surface. The clamping plate and the vertical plate are clamped on both sides of the formwork, and the inclined surface design improves the clamping stability effect.

[0023] Preferably, the length of the clamping plate is not less than one-third of the height of the formwork. This further improves the clamping effect on the formwork.

[0024] Preferably, the number of the bolts on the second vertical plate is not less than two. This ensures an effective connection between the fixture and the formwork.

[0025] Through the above technical solutions, compared with the prior art, the present utility model discloses a fixture for reinforcing a multi-porous cement stabilized macadam pavement formwork.

[0035] A first vertical plate 2, which is vertically fixed at one end of the bottom end surface of the support plate 1;

[0036] A second vertical plate 3, which is vertically fixed at the other end of the bottom end surface of the support plate 1;

[0037] Clamping plates 5, there are two clamping plates 5 which are vertically fixed on the bottom end surface of the support plate 1, and there is a gap for clamping the formwork 8 between the two side walls of the clamping plate 5 opposite to the first vertical plate 2 or the second vertical plate 3;

[0038] Bolts 4, there are multiple bolts 4 which are respectively rotatably connected to the panels of the first vertical plate 2 and the second vertical plate 3, and the threaded ends thereof can abut against the side wall of the opposite formwork 8.

[0039] In the specific construction process, the width and height of the inner cavity formed between the two side formworks are both 27 cm. The formwork close to the road surface abuts against the road surface, the formwork close to the slope side abuts against the slope soil body and is supported by wooden beams.

The first vertical plate and the clamping plate, and the second vertical plate and the clamping plate are respectively clamped on both sides of the formwork, and the bolts abut against the side wall of the formwork, so that the fixture can be fastened to the formwork to prevent the fixture from falling off. There is no need to use tie rods, and the constructed porous cement stabilized macadam is more complete and has excellent drainage effect.

[0040] In order to further optimize the above technical solution and ensure an effective connection between the fixture and the formwork after the fixture is clamped to the formwork, nuts 7 are fixed on the panels of the first vertical plate 2 and the second vertical plate 3, and the axis of the bolt 4 is arranged perpendicular to the side wall of the formwork 8 and is screwed with the nut 7.

[0041] In order to further optimize the above technical solution and improve the stability of the fixture for clamping and reinforcing the formwork, a supporting plate 6 is further included.
