Description

Technical Field

[0001] The utility model relates to the field of road foundation formwork, in particular to a road foundation side formwork support and positioning device. Background Art

[0002] When pouring concrete on the road foundation, it is necessary to set up a spliced ​​side formwork on the side of the roadbed. When installing the side formwork, it is necessary to mark and position it. After positioning, the positioning rod is inserted from the positioning sleeve of the support frame into the roadbed through the outer fixing component to achieve fixation. In order to prevent the side formwork from position deviation when the positioning rod is inserted, multiple support rods are evenly placed on the inside of the existing side formwork for support (such as Figure 3 As shown), after the positioning rod is driven in and the shape is fixed, the support rod is taken out. However, since the two ends of the support rod are in tight contact with the inner wall of the side template, it is necessary to knock the support rod out of contact when taking it out, which is very troublesome and laborious. Utility Model Content

[0003] In order to solve the above-mentioned problems, the utility model provides a road foundation side formwork support positioning device.

[0004] The utility model is realized through the following technical solutions:

[0005] A road foundation side formwork support and positioning device includes side formworks arranged on both sides of the road foundation, pre-positioning components are arranged on the top of the side formworks on both sides, the pre-positioning components include a horizontal movable frame, telescopic support wheel components supported on the top of the side formworks are arranged on both sides of the movable frame, the lower part of the telescopic support wheel component is provided with a positioning wheel component supported on the lower part of the side formwork for sliding adjustment, and a fixed component is arranged on the outer side of the side formwork.

[0006] Further optionally, the telescopic support wheel assembly includes a telescopic rod telescopically connected to the two sleeves of the mobile frame, a support wheel is installed at the end of the telescopic rod, and the support wheel is provided with a guide groove that is clamped on the top of the side template.

[0007] Further optionally, the positioning wheel assembly includes a sliding frame, the two sides of the sliding frame are slidably connected to the corresponding telescopic rods on both sides through sliding sleeves, the lower part of the sliding frame is connected to multiple connecting rods, and the ends of the connecting rods are equipped with positioning wheels supported on the inner side of the lower part of the side template.

[0015] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0016] like Figure 1 As shown, a road foundation side formwork support and positioning device includes side formworks 1 arranged on both sides of the road foundation, and pre-positioning components are provided on the top of the side formworks 1 on both sides. The pre-positioning components can realize the pre-positioning of the side formworks 1 on both sides. The pre-positioning components include a horizontal movable frame 4, and the movable frame 4 is made of lightweight aluminum alloy, which is more labor-saving in subsequent transportation. Telescopic support wheel assemblies supported on the top of the side formworks 1 are provided on both sides of the movable frame 4, and a positioning wheel assembly supported on the lower part of the side formworks 1 for sliding adjustment is provided on the lower part of the telescopic support wheel assembly, and a fixed assembly is provided on the outer side of the side formwork 1.

[0017] like Figure 2 As shown, the telescopic support wheel assembly includes a telescopic rod 6 telescopically connected to the two sleeves 5 of the mobile frame 4, and a support wheel 7 is installed at the end of the telescopic rod 6. The support wheel 7 is provided with a guide groove 8 that is clamped on the top of the side template 1. The guide groove 8 is clamped on the top of the upper part of the side template 1 to not only support its upper part, but also prevent the support wheel 7 from falling off from the side template 1.

[0018] like Figure 2As shown, the positioning wheel assembly includes a sliding frame 9, and the two sides of the sliding frame 9 are slidably connected to the corresponding telescopic rods 6 on both sides through sliding sleeves 10. The lower part of the sliding frame 9 is connected to a plurality of connecting rods 12, and the ends of the connecting rods 12 are installed with positioning wheels 13 supported on the inner side of the lower part of the side template 1. The positioning wheel 13 is arranged horizontally, which can support the lower part of the side template 1. When adjusting the position of the positioning wheel 13, it is necessary to ensure that it and the support wheel 7 are kept on the same longitudinal plane, so that the supported side template 1 is horizontal and vertical.

[0019] like Figure 2 As shown, a locking screw 11 is installed on the sleeve 5 and the sliding sleeve 10.

[0020] The fixing assembly includes a plurality of support frames 2 fixed on the outside of the side formwork 1. The positioning sleeves on the outside of the support frames 2 can be inserted with positioning rods 3 for fixing. The positioning rods 3 are used to fix the support frames 2 firmly, thereby ensuring the stability of the subsequent concrete pouring in the side formwork 1.

[0021] The implementation principle of the road foundation side formwork support positioning device in the embodiment of the present application is as follows:

[0022] When placing the side formwork 1 according to the marked lines, first place the pre-positioning assembly. When placing, support the guide grooves 8 of the support wheels 7 on both sides of the telescopic support wheel assembly on the edge of the side formwork 1. At the same time, according to the different spacing widths of the side formwork 1, the locking screws 11 of the sleeve 5 can be loosened, and the length of the telescopic rod 6 can be adjusted from the sleeve 5 to achieve the adjustment of the support span. After adjustment, tighten the locking screws 11 on the sleeve 5;

[0023] After the cam 11 is released, the cam 13 is released, and the cam 11 is released to the left, and the cam 13 is released to the right, and the cam 13 is released to the right, and the cam 13 is released to the right, and the cam 13 is released to the left, and the cam 13 is released to the right, and the cam 13 is released to the right, and the cam 13 is released to the right, and the cam 13 is released to the left, and the cam 13 is released to the right, and the cam 13 is released
