Description

Technical Field

[0001] The utility model relates to a concrete pouring template, in particular to a concrete pouring single-side template support reinforcement system at a vertical misalignment of a filter tank bottom. Background Art

[0002] Some water purification plant pools combine ozone contact pools, activated carbon filter pools, and V-shaped filter pools into one. This type of large pool is completed by setting up the formwork as a whole and pouring concrete in one go. There is a 3-meter-high staggered platform at the bottom of this type of pool. When setting up the concrete pouring formwork for the pool body, a brick membrane is generally built near the soil at the staggered platform, which serves as the outer formwork for pouring concrete at the staggered platform. The inner formwork at the staggered platform uses a wooden formwork, and the height of the staggered platform is about 3 meters. The design requires that the concrete bottom plate of the high platform pool bottom be cast as a whole at one time with the wall at the high and low staggered platform. Not only the concrete in the wall, but also the concrete at the bottom of the high platform pool together constitute the pressure on the inner vertical formwork for pouring the staggered platform. The inner formwork will be under great lateral pressure, and it is easy to cause mold expansion. How to reinforce the inner formwork at the staggered platform has become a problem that needs to be solved during on-site construction. Summary of the invention

[0003] The utility model provides a single-side template support reinforcement system for concrete pouring at a vertical misalignment of a filtering pool bottom, solving the technical problem of how to reinforce the inner template at the misalignment.

[0004] The utility model solves the above technical problems through the following technical solutions:

[0005] A single-sided formwork support and reinforcement system for concrete pouring at a vertical misalignment of a filtering pool bottom comprises a low pool bottom concrete raft slab that has been poured, a brick-formed masonry wall is arranged on the left side of the low pool bottom concrete raft slab, soil is arranged on the left side of the brick-formed masonry wall, and a high pool bottom concrete pouring formwork system is arranged on the left side of the top of the brick-formed masonry wall; a single-sided inner formwork is arranged on the low pool bottom concrete raft slab on the right side of the brick-formed masonry wall, a vertical wooden slat is arranged on the left side of the single-sided inner formwork, a horizontal steel pipe is arranged on the vertical wooden slat, a vertical steel pipe is arranged on the horizontal steel pipe, and tension bolts are penetrated on the vertical steel pipe; a steel bar column is pre-buried on the low pool bottom concrete raft slab on the right side of the single-sided inner formwork, and an oblique brace is arranged between the steel bar column and the vertical steel pipe.

[0006] A horizontal brace is arranged between the steel bar column and the vertical steel pipe directly below the diagonal brace.

[0007] A partition wall left wall formwork system higher than the high pool bottom concrete casting formwork system is arranged above the high platform pool bottom concrete casting formwork system; a left-inclined masonry wall top inclined surface is arranged at the top of the brick formwork masonry wall.

[0008] The utility model changes the traditional single-sided formwork reinforcement method of using horizontal steel pipes and reserved tension screws for tensioning, to a method in which in addition to the horizontal steel pipes for tensioning, tensioning steel pipes are also added vertically, and Φ25 steel bars with a spacing of 2 meters are embedded in the raft slab passing through the low pool bottom as support points. The bottom and middle part of the one-way formwork are reinforced by a stable triangular support frame, and then each triangular support frame is connected into a stable three-dimensional support system to resist the larger impact force of concrete pouring on the one-sided formwork. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0010] The utility model is described in detail below with reference to the accompanying drawings:

[0011] A single-sided formwork support and reinforcement system for concrete pouring at a vertical misalignment of a filter pool bottom comprises a low pool bottom concrete raft 1 that has been poured, a brick-formed masonry wall 2 is arranged on the left side of the low pool bottom concrete raft 1, a soil body is arranged on the left side of the brick-formed masonry wall 2, a high pool bottom concrete pouring formwork system 3 is arranged on the left side of the top of the brick-formed masonry wall 2, and the high pool bottom concrete pouring formwork system 3 has been set up; a single-sided inner formwork 4 is arranged on the low pool bottom concrete raft 1 on the right side of the brick-formed masonry wall 2, a vertical wooden slat 5 is arranged on the left side of the single-sided inner formwork 4, and a vertical wooden slat 5 is arranged on the vertical wooden slat 5. A transverse steel pipe 6 is arranged on it, and tension bolts are embedded in the brick-formed wall 2. After the tension bolts cooperate with the vertical wooden slats 5 and the transverse steel pipe 6, the single-sided inner formwork 4 is fixed; vertical steel pipes 7 are arranged on the transverse steel pipe 6, and the vertical steel pipes 7 are arranged at intervals. A portion of the tension bolts 8 embedded in the brick-formed wall 2 pass through the single-sided inner formwork 4, the vertical wooden slats 5, the transverse steel pipe 6 and the vertical steel pipe 7 in sequence to reinforce and fix the single-sided inner formwork 4; a steel bar column 9 is embedded in the low pool bottom concrete raft 1 on the right side of the single-sided inner formwork 4, and a diagonal brace 10 is arranged between the steel bar column 9 and the vertical steel pipe 7.

[0012] A horizontal brace 11 is provided between the steel bar column 9 and the vertical steel pipe 7 directly below the diagonal brace 10 . The vertical steel pipe 7 , the diagonal brace 10 and the horizontal brace 11 form a stable supporting triangle frame to reinforce and support the single-sided inner formwork 4 .

[0013] A partition wall left side wall formwork system 12 is arranged above the high platform pool bottom concrete casting formwork system 3, which is higher than the high platform pool bottom concrete casting formwork system 3. The top of the precast partition wall composed of the brick formwork wall 2, the partition wall left side wall formwork system 12 and the single-sided inner formwork 4 is higher than the precast high platform pool bottom concrete raft slab. Therefore, the partition wall left side wall formwork system 12 can be arranged on the upper part of the precast partition wall, which is higher than the precast high platform pool bottom concrete raft slab. A left-inclined masonry wall top inclined surface 13 is arranged on the top of the brick formwork wall 2, so that when concrete is poured on the partition wall and the high platform pool bottom concrete raft slab, the concrete can enter the casting space of the partition wall more smoothly.
