TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a formwork support structure for a floating plate on a river retaining wall and a construction method thereof. BACKGROUND

[0002] In some river construction processes, retaining walls are cast on both sides of the river, and the height of the retaining wall exceeds 10m. In order to cast a floating plate on the top of the retaining wall as an observation walkway, a support needs to be erected for supporting the formwork of the floating plate. The preparation time of high formwork is relatively long if experts are required to demonstrate, which will seriously affect the site construction period. If the support is erected on the riverbed, the entire frame body has a large workload, a large height-width ratio, and poor stability. SUMMARY

[0003] In order to overcome the defects of the prior art, a formwork support structure for a floating plate on a river retaining wall and a construction method thereof are provided to solve the problems of long construction time and large workload in the construction of a floating plate on a river retaining wall using traditional supports.

[0004] To achieve the above-mentioned purpose, a formwork support structure for a floating plate on a river retaining wall is provided, comprising:

[0005] a retaining wall cast on opposite sides of the river;

[0006] an enclosure structure arranged on the opposite sides of the two retaining walls, and an inner support connected between the enclosure structures on the opposite sides of the river;

[0007] a support body arranged between the two retaining walls, the support body being mounted on the inner support, the side portion of the support body being connected to the retaining wall, and the top portion of the support body being flush with the top portion of the retaining wall for supporting the formwork of the floating plate.

[0008] Further, the number of inner supports is multiple, and the multiple inner supports are arranged in a vertical direction, each inner support comprising a plurality of support bodies arranged at intervals along the length direction of the river, and the support body being mounted on the plurality of support bodies at the top layer.

[0009] Further, the plurality of support bodies at the top layer are laid with a plurality of cross beams arranged at intervals along the length direction of the support body, and a plurality of clamping ribs are vertically arranged on the support body, and adjacent two clamping ribs are arranged on the cross beam.

[0010] Further, a dowel is vertically arranged on the cross beam, a lower end of a vertical rod of the support body is formed with a socket hole, and the dowel is detachably inserted into the socket hole.

[0011] Further, the side portion of the support body is connected to the inner side of the retaining wall through a wall connecting assembly.

[0012] Further, the wall connecting component comprises:

[0013] a vertical pipe embedded in the retaining wall;

[0014] a horizontal pipe, one end of the horizontal pipe being embedded in the retaining wall, one end of the horizontal pipe being connected to the vertical pipe through a fastener, and the side of the bracket body being connected to the other end of the horizontal pipe.

[0015] The present application provides a construction method of a formwork support structure for a floating slab on a river retaining wall, comprising the following steps:

[0016] constructing a containment structure on opposite sides of the river and connecting an inner support between the containment structures on opposite sides of the river;

[0017] constructing two retaining walls between the two containment structures;

[0018] providing a bracket body between the two retaining walls;

[0019] mounting the bracket body on the inner support and connecting the side of the bracket body to the retaining wall, so that the top of the bracket body is flush with the top of the retaining wall for supporting the formwork of the floating slab.

[0020] The present application has the beneficial effect that the construction preparation period of the formwork support structure for the floating slab on the river retaining wall is short.

The formwork support structure for the floating slab on the river retaining wall of the present application adds embedded steel bars, I-beams, etc. in the concrete inner support, so that the entire bracket body transmits force to the inner support, avoiding the occurrence of a large-scale dangerous sub-item project, reducing the time for expert demonstration of the scheme, and greatly reducing the construction preparation time.

[0021] The formwork support structure for the floating slab on the river retaining wall of the present application has a high construction safety factor. According to the traditional super-dangerous high formwork system, the requirements for formwork design and erection and related measures are high, the height-width ratio is large, the stability is poor, and the control difficulty is large during construction. In addition, when a landing type formwork support frame is used, it is easy to be washed by river water, and the overall formwork support system has a large safety risk. The formwork support structure for the floating slab on the river retaining wall of the present application transmits the formwork system to the concrete inner support, greatly reduces the formwork height, and does not belong to a super-dangerous formwork system, so the construction safety is effectively improved.

[0043] A dowel bar 33 is arranged vertically on the cross beam 31. The lower end of the vertical rod 34 of the bracket body 3 is formed with a socket hole. The dowel bar 33 is detachably inserted into the socket hole.

[0044] In the embodiment, the cross beam is an I-beam.

[0045] Referring to Figure 4 and Figure 6 As shown in the figure, the side of the bracket body 3 is connected to the inner side of the retaining wall 1 through a wall connecting assembly 35.

[0046] Specifically, referring to Figure 6 As shown in the figure, the wall connecting assembly 35 includes a vertical pipe 351, a horizontal pipe 352, and a fastener 353.

[0047] In the embodiment, the wall connecting assembly is embedded in the retaining wall. Specifically, the vertical pipe 351 is embedded in the retaining wall 1. One end of the horizontal pipe 352 is embedded in the retaining wall 1. The one end of the horizontal rod is connected to the vertical pipe 351 through the fastener 353.

[0050] The present application provides a construction method of a formwork support structure for a floating plate on a river retaining wall, comprising the following steps:

[0051] S1, constructing a containment structure 2 on opposite sides of the river, and connecting an inner support 21 between the containment structures 2 on opposite sides of the river.

[0052] S2, constructing two retaining walls 1 between the two containment structures 2.

[0053] S3, setting a support body 3 between the two retaining walls 1.

[0055] The construction preparation period of the formwork support structure for the floating plate on the river retaining wall of the present application is short. When the conventional floor support formwork construction system is constructed, it belongs to a large-scale dangerous sub-item project that needs expert demonstration. The formwork support structure for the floating plate on the river retaining wall of the present application adds embedded steel bars, H-shaped steels, etc. in the concrete inner support, so that the entire support body transmits force to the inner support, avoiding the occurrence of a large-scale dangerous sub-item project, reducing the expert demonstration time of the scheme, and greatly reducing the construction preparation time.

[0056] The formwork support structure for the floating plate on the river retaining wall of the present application has a high construction safety factor. According to the traditional super-dangerous high formwork system, the requirements of formwork design and erection and related measures are high, the height-width ratio is large, the stability is poor, and the control difficulty is large during the construction process. In addition, when the floor type formwork support frame is used, it is easy to be washed by river water, and the overall formwork support system has a large safety risk. The formwork support structure for the floating plate on the river retaining wall of the present application transmits the formwork system to the concrete inner support, greatly reduces the formwork height, and does not belong to the super-dangerous formwork system, so the construction safety will be effectively improved.
