Compared with the traditional cleaning means, the template dismantling efficiency is high, the construction period is shortened, the cost is reduced, and the safety hazards of workers are reduced.

Description

Technical Field

[0001] This invention belongs to the technical field of dismantling formwork at the bottom of trestle bridges, and specifically relates to a dismantling structure and method for dismantling formwork at the bottom of trestle bridges. Background Technology

[0002] With the development of large and medium-sized cities, urban land resources are becoming increasingly scarce, leading to rising land prices and a general increase in land utilization. The area within the land boundary that can be used as material storage yards and construction access routes is becoming increasingly limited, posing significant challenges to the excavation and transportation of excavated soil for foundation pits and the construction of basements. Therefore, setting up construction trestle bridges around the foundation pits has become a necessary measure. By setting up trestle bridges, conditions for soil transportation can be significantly improved, the efficiency of excavation and removal of excavated soil can be increased, the construction period can be shortened, and project costs can be saved.

[0003] During the construction of trestle bridges, a concrete base layer is typically installed. However, removing this concrete base layer is cumbersome and non-recyclable, leading to high costs. Therefore, a construction method combining recycled formwork with economical isolation materials has been adopted to replace the base layer. After the trestle bridge construction is completed and the excavation of the foundation pit begins, the formwork and blocks adhering to the bottom of the trestle bridge panels should be promptly removed to ensure the safety of subsequent construction beneath the trestle. Currently, most trestle bridge panel removal involves workers climbing scaffolding to manually clean the formwork, which is not only time-consuming and labor-intensive, affecting dismantling efficiency, but also prone to grout leakage during concrete pouring, causing adhesion between the trestle bottom and the economical isolation materials and formwork. After the soil at the bottom of the formwork is excavated, the formwork and the soil blocks at its base are extremely prone to falling off due to gravity, posing a safety risk to workers. Therefore, we propose a dismantling structure and method for removing the formwork at the bottom of trestle bridges to solve the above problems. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a dismantling structure and method for removing the formwork at the bottom of a trestle bridge, thus resolving the issues of low formwork removal efficiency and safety risks to workers.

[0005] This invention is achieved through the following solution: a dismantling structure for removing the formwork at the bottom of a trestle bridge, pre-installed between the bottom of the trestle bridge and an economical insulating material, the dismantling structure comprising:

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

[0007] A rope is threaded through the opening, with both ends of the rope extending outward from the two ends of the opening to form two traction parts for pulling down.

[0008] A further improvement of the present invention for the removal structure of the template at the bottom of the trestle bridge is that the number of the openings is multiple, and the multiple openings are arranged along the length / width direction of the bottom of the trestle bridge. The number of ropes is the same as the number of openings, and the multiple ropes are respectively threaded through the multiple openings.

[0009] A further improvement of the present invention for the removal structure of the template at the bottom of the trestle is that the limiting member includes a plurality of limiting strips spaced apart along the width / length direction of the bottom of the trestle. Each limiting strip forms a plurality of openings along the length / width direction of the bottom of the trestle between itself and the bottom of the trestle. The plurality of openings on each limiting strip correspond to the plurality of openings on adjacent limiting strips, and the corresponding openings on all limiting strips combine to form the through-hole.

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

[0011] A method for removing the formwork at the bottom of a trestle bridge includes the following steps:

[0012] Provide the dismantling structure as described above, and pre-install the dismantling structure between the bottom of the trestle and the economical isolation material;

[0013] After the soil at the bottom of the formwork is removed, pull down the two traction parts to allow the ropes, limiters, economical isolation materials, and formwork to detach from the bottom of the trestle.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] This invention uses a limiting component and rope pre-installed between the bottom of the trestle and the economical isolation material. By pulling down the two traction parts of the rope, the entire template can be directly and quickly detached from the bottom of the trestle, avoiding the pieces falling off one by one. Moreover, the entire dismantled structure can be recycled and reused. Compared with traditional cleaning methods, this invention has high template dismantling efficiency, shortens the construction period, reduces costs, and reduces safety hazards for workers.

[0019] To address the issues of low efficiency and safety risks to workers during formwork removal, this invention provides a removal structure and method for removing formwork from the bottom of a trestle bridge. The following detailed description, in conjunction with accompanying drawings, further illustrates this removal structure and method for removing formwork from the bottom of a trestle bridge.

[0020] See Figures 1-2 As shown, a dismantling structure for removing the formwork at the bottom of a trestle bridge is pre-installed between the bottom of the trestle bridge 1 and the economical isolation material 4. The dismantling structure includes:

[0021] A limiting component is laid between the bottom of the trestle 1 and the economical isolation material 4, and an opening 6 is formed between the limiting component and the bottom of the trestle 1.

[0022] Rope 3 is threaded through the opening 6, and both ends of rope 3 extend outward from the two ends of the opening 6 to form two traction parts for pulling down.

[0023] By pulling down the two traction parts of the rope 3, the template 5 can be directly and quickly detached from the bottom of the trestle 1, avoiding the pieces from falling off one by one; and the entire dismantled structure can be recycled and reused after dismantling.

[0024] Among them, see Figure 1 As shown, there are multiple openings 6, and the multiple openings 6 are arranged along the length / width direction of the bottom of the trestle 1. The number of ropes 3 is the same as the number of openings 6, and the multiple ropes 3 are respectively threaded through the multiple openings 6.

[0025] See Figure 2 As shown, the limiting component includes multiple limiting strips 2 spaced apart along the width / length direction of the bottom of the trestle 1. Each limiting strip 2 forms multiple openings 7 along the length / width direction of the bottom of the trestle 1 between itself and the bottom of the trestle 1. The multiple openings 7 on each limiting strip 2 correspond to the multiple 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 limiting strips 2 can be determined according to the span of the board;

[0027] By using multiple through-holes 6 in conjunction with multiple ropes 3, the force can be balanced when pulling down the ropes 3, thus allowing the template 5 and other structures to be quickly detached from the bottom of the trestle 1, which is beneficial for operation.

[0028] Among them, the limiting component is bonded to the economical isolation material 4.

[0029] Specifically, the limiting strip 2 can be a nylon buckle or other adhesive material that connects / bonds to the economical isolation material 4, so that the limiting strip 2 and the economical isolation material 4 can be detached as a whole, which also facilitates subsequent overall recycling and reuse.

[0030] A method for removing the formwork at the bottom of a trestle bridge includes the following steps:

[0031] Provide the dismantling structure as described above, and pre-install the dismantling structure between the bottom of the trestle 1 and the economical isolation material 4;

[0032] After the soil at the bottom of template 5 is removed, pull down the two traction parts to make the rope 3, the limiting piece, the economical isolation material 4, and the template 5 detach from the bottom of the trestle 1.
