Description

Technical Field

[0001] The invention belongs to the technical field of dismantling templates at the bottom of a trestle, and in particular relates to a dismantling structure and a dismantling method for dismantling templates at the bottom of a trestle. Background Art

[0002] With the development of large and medium-sized cities, urban land resources are becoming increasingly scarce, followed by rising land prices and generally improved land utilization rates. There are fewer and fewer sites within the land red line that can be used as material yards and construction passages, which brings great difficulties to the excavation and transportation of foundation pits and basement construction. Therefore, setting up construction trestles around the foundation pits has become a necessary means. By setting up trestles, the conditions for earthwork transportation can be greatly improved, the efficiency of earthwork excavation and transportation can be improved, the construction period can be shortened, and the project cost can be saved.

[0003] A concrete bottom cushion is usually set during the construction of a pier. Since the concrete bottom cushion is troublesome to chisel out and cannot be recycled, the cost is high. Therefore, a construction method is adopted by using a combination of waste formwork and economic isolation materials to replace the bottom cushion of the pier bridge. After the construction of the supporting pier and when the foundation pit is excavated, the formwork and blocks adsorbed on the bottom of the pier bridge should be removed in time to ensure the safety of subsequent construction under the pier. Most of the existing pier bottom operations are performed by workers climbing up on scaffolding and then manually cleaning the formwork, which is not only time-consuming and labor-intensive, affecting the demolition efficiency, but also when pouring concrete for the construction of the pier, leakage will occur, resulting in adhesion between the bottom of the pier and the economic isolation material and the formwork. After the soil at the bottom of the formwork is excavated, due to gravity, the formwork and the soil blocks at the bottom of the formwork are extremely likely to fall off piece by piece, posing a safety risk to the workers. To this end, a dismantling structure and a dismantling method for dismantling the formwork at the bottom of the pier are proposed to solve the above problems. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a dismantling structure and a dismantling method for dismantling the template at the bottom of the pier, which solves the problems of low efficiency in template dismantling and safety risks for workers.

[0005] The present invention is implemented by the following scheme: a dismantling structure for dismantling the template at the bottom of the trestle, which is preset between the bottom of the trestle and the economic isolation material, and the dismantling structure includes:

[0006] A limiting member is laid between the bottom of the trestle and the economical isolation material, and a through opening is formed between the limiting member and the bottom of the trestle;

[0007] The rope is passed through the through hole, and two ends of the rope extend outwards from two ends of the through hole respectively to form two traction parts for the pull-down operation.

[0008] A further improvement of the dismantling structure for dismantling the template at the bottom of the pier of the present invention is that the number of the through-holes is multiple, and the multiple through-holes are arranged along the length / width direction of the bottom of the pier, the number of the ropes is consistent with the number of the through-holes, and the multiple ropes are respectively passed through the multiple through-holes.

[0009] A further improvement of the dismantling structure for dismantling the template at the bottom of the pier of the present invention is that the limiting member includes a plurality of limiting strips arranged at intervals along the width / length direction of the bottom of the pier, and a plurality of openings arranged along the length / width direction of the bottom of the pier are formed between each of the limiting strips and the bottom of the pier, the plurality of openings on each of the limiting strips respectively correspond to the plurality of openings on adjacent limiting strips, and the corresponding openings on all the limiting strips are combined to form the through opening.

[0010] A further improvement of the dismantling structure for dismantling the template at the bottom of the trestle bridge of the present invention is that the limiting member is adhered to the economical isolation material.

[0011] A method for removing a template at the bottom of a trestle comprises the following steps:

[0012] Providing a demolition structure as described above, and presetting the demolition structure between the bottom of the trestle and the economic isolation material;

[0013] After the soil at the bottom of the formwork is removed, the two traction parts are pulled downward to make the ropes, the limit pieces, the economical isolation materials and the formwork fall off from the bottom of the trestle.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The present invention reserves a limit piece and a rope between the bottom of the trestle and the economical isolation material, and pulls down the two traction parts of the rope, so as to directly and quickly remove the template as a whole from the bottom of the trestle to avoid falling piece by piece; and the entire demolition structure after dismantling can be recycled and reused; compared with traditional cleaning methods, the template dismantling efficiency of the present invention is high, the construction period is shortened, the cost is reduced, and the safety hazards of workers are reduced.

[0019] In order to solve the problem of low template removal efficiency and safety risks for workers, the present invention provides a dismantling structure and method for dismantling the template at the bottom of a trestle. The dismantling structure and method for dismantling the template at the bottom of a trestle are further described below with specific embodiments combined with the accompanying drawings.

[0020] See also Figure 1-2 As shown, a dismantling structure for dismantling the template at the bottom of the trestle is preset between the bottom of the trestle 1 and the economic isolation material 4, and the dismantling structure includes:

[0021] The limiting member is laid between the bottom of the trestle 1 and the economical isolation material 4, and a through opening 6 is formed between the limiting member and the bottom of the trestle 1;

[0022] The rope 3 is passed through the through hole 6, and two ends of the rope 3 extend outward from two ends of the through hole 6 respectively to form two traction parts for the pull-down operation.

[0023] By pulling down the two traction parts of the rope 3, the template 5 can be directly and quickly removed from the bottom of the trestle 1 as a whole to avoid falling off piece by piece; and the entire demolished structure can be recycled and reused after being dismantled.

[0024] Among them, see Figure 1 As shown, there are multiple through-holes 6, and the multiple through-holes 6 are arranged along the length / width direction of the bottom of the trestle 1, the number of ropes 3 is consistent with the number of through-holes 6, and the multiple ropes 3 are respectively passed through the multiple through-holes 6;

The plurality of openings 7 on each limiting strip 2 respectively correspond to the plurality of openings 7 on adjacent limiting strips 2, and the corresponding openings 7 on all limiting strips 2 are combined to form a through opening 6.

[0026] Specifically, the number of ropes 3 and limit strips 2 can be determined according to the board span;

[0027] By cooperating with the multiple through-holes 6 and the multiple ropes 3, the force can be balanced when the ropes 3 are pulled down, so that the template 5 and other structures can be quickly dropped from the bottom of the pier 1, which is convenient for operation.

[0028] The limiting member is bonded to the economical insulating material 4 .

[0029] Specifically, the limiting strip 2 can be a nylon buckle or other adhesive material connected / adhered to the economical insulating material 4, so that the limiting strip 2 and the economical insulating material 4 can be detached as a whole, which is also convenient for subsequent overall recycling and reuse.
