Description

Technical Field

[0001] The utility model relates to the field of construction engineering, in particular to an anti-seepage support device for a top plate inner formwork bracket, especially for supporting the top plate formwork during one-time pouring of multi-layer superimposed structure buildings such as canals, pipe corridors, canals, etc. Background Art

[0002] In the context of the increasingly serious negative impact of the construction industry on the environment, in order to ensure the sustainable development of my country's construction industry, it is particularly important to implement the "four savings and one environmental protection". With the gradual deepening of the concept of "four savings and one environmental protection", the design of water plants at this stage tends to be superimposed and intensively arranged. The design of multiple pools has gradually matured, and the construction unit must strengthen the improvement and improvement of the cast-in-place construction technology of reinforced concrete in superimposed structures. In the construction of traditional reinforced concrete structures, after the bottom plate is cast, water-stopping measures are set on the pool wall and then the top plate concrete is cast to control the integrity and impermeability of the pool. The superimposed pools, canals, pipe corridors and other water treatment facilities are arranged in multiple layers. The traditional construction process has a long construction period and requires a construction process of cyclic steel bar binding-formwork support-concrete pouring. The construction progress is slow and is easily affected by factors such as construction joints and secondary pouring, resulting in the integrity and impermeability of the pool not meeting the requirements.

[0016] The present invention is further described in detail below in conjunction with the embodiments:

[0017] like Figure 1-Figure 2As shown, a top plate internal formwork support anti-seepage support device includes a steel pipe 2 connected to the N+1th layer top plate formwork support, where N is a natural number greater than or equal to 1. The outer side of the steel pipe 2 is sleeved with a detachable sleeve 1 made of PVC material, which can make the steel pipe 2 smoothly dismantled and recycled. A steel support 8 is sleeved below the steel pipe 2, and the steel support 8 includes a steel top support 4, a steel column 3 and two steel bottom supports 5. The steel top support 4, the steel column 3 and one steel bottom support 5 are welded into a "earth"-shaped structure. A steel plate water stop ring 6 is welded on the steel column 3, and the spacing between the steel plate water stop ring 6 and the steel top support 4 and the steel bottom support 5 is the same. The two steel bottom supports 5 are welded into a "cross"-shaped structure on the plane, and the bottom of the steel support 8 is placed in a concrete pad 7, which is prefabricated with concrete of the same grade. The concrete pad 7 is provided with a "cross"-shaped slot for placing the "cross"-shaped structure, which effectively ensures the overall rigidity of the formwork system and can achieve that the formwork does not move or deform when pouring concrete. The concrete pad 7 is placed in the steel grid on the bottom formwork of the Nth layer top plate.

[0018] Combination Figure 3-Figure 4 The following is a method for using the anti-seepage support device for the internal formwork support of the utility model:

[0019] 1. Prefabricated components:

[0020] According to the construction plan, a concrete pad 7 with a "cross"-shaped groove is prefabricated on the surface layer, and the strength of the concrete pad 7 is consistent with the structural strength; a steel support 8 welded from a steel top support 4, a steel column 3, a steel bottom support 5, and a water stop ring 6 is prefabricated and properly placed for use after prefabrication.

[0021] 2. Construction of one layer of formwork support:

[0022] A top slab formwork support is set up above a layer of already cast bottom slab. After qualified acceptance, the top slab formwork and top slab reinforcement are installed and the acceptance is completed.

[0023] 3. Construction of second-layer formwork support:

[0024] Place the prefabricated concrete pad 7 in the steel grid on the bottom formwork of the first top plate according to the plan, place the steel support 8 above the concrete pad 7, align the steel support 8 with the first layer of risers, and place the sleeve 1 and the steel pipe 2 on the steel support 8. When placing the steel pipe 2, two people are required to cooperate to complete the installation of the second-layer formwork support. After the formwork support installation is completed and accepted, the top plate formwork and top plate steel bars are installed and the acceptance is completed.

[0025] 4. Construction of three-layer formwork support:

[0026] Place the prefabricated concrete pad 7 in the steel grid on the bottom formwork of the second-floor top plate according to the plan, place the steel support 8 above the concrete pad 7, align the steel support 8 with the second-floor riser, and place the sleeve 1 and the steel pipe 2 on the steel support 8. When placing the steel pipe 2, two people are required to cooperate to complete the installation of the second-floor formwork support. After the formwork support installation is completed and accepted, install the top plate formwork and top plate steel bars and complete the acceptance.

[0027] 5. Multi-layer structure concrete pouring:

[0028] The installation of the pool wall formwork is interspersed with the above steps. After completion, the concrete pouring of the multi-layer structure begins. The pouring method is to pour the side wall first, then the top plate, from bottom to top, and in a reciprocating manner. When the first layer of the pool wall is poured to the first layer of the top plate, the rod workers and the plastering and finishing personnel will enter the top plate to vibrate and finish the surface. The plastering personnel will circulate back and forth in different areas to carry out the plastering work. When the top plate is initially solidified in one area, the second layer of the pool wall and the top plate will be poured in this area. When pouring to the second layer of the top plate, the rod workers and the plastering and finishing personnel will enter the top plate of the second layer of the top plate to vibrate and finish the surface. When the second layer of the top plate is initially solidified in one area, the third layer of the pool wall and the top plate will be poured in this area. This cycle will continue until the pouring work is successfully completed.

[0029] 6. Follow-up work:

[0030] After the concrete pouring is completed and the concrete reaches the demoulding strength, the template can be removed; the steel pipe 2 is recycled, the steel support 8 remains in the concrete, and the holes left by the removal of the steel pipe 2 are filled with concrete of the same grade mixed with a micro-expansion agent.
