Description

Technical Field

[0001] The invention relates to a T-shaped beam, in particular to a cover plate tooling for pouring a drainage hole of the T-shaped beam and a use method thereof, belonging to the technical field of bridge construction. Background Art

[0002] During the construction of the protective layer of the T-beam bridge deck, the concrete construction requirements for the drainage hole position must be beautiful, and the inverted "T" shape with a large top and a small bottom meets the drainage requirements of the bridge deck. Traditional construction uses a mortar bucket as a mold. The mortar bucket cannot be fixed during construction and will shift during concrete pouring, resulting in irregular appearance dimensions of the protective layer concrete above the pipe mouth, making it impossible to install the drainage pipe cover normally, failing to meet the acceptance standards, and resulting in unqualified quality. Summary of the invention

[0003] The technical problem to be solved by the present invention is: to provide a cover plate tooling for pouring T-beam drainage holes and a method of using the same. By setting a positioning plate and a positioning ring, the tooling can be accurately positioned in the drainage hole, which is convenient for pouring without displacement, thus solving the problem of substandard drainage hole pouring quality in the past.

[0004] The technical solution of the present invention is: a cover plate tooling for pouring T-beam drainage holes, which includes a positioning plate, a positioning ring and a cover plate assembly. The positioning ring is a conical cylinder structure that is larger at the top and smaller at the bottom. A cross plate is fixedly connected to the inner side of the bottom end of the positioning ring, the positioning plate is fixedly connected to the bottom end of the cross plate, a connecting rod is vertically fixedly connected to the center of the cross plate, a handle is fixedly connected to the top end of the connecting rod, and the cover plate assembly is movably sleeved on the connecting rod.

[0005] The cover plate assembly comprises a cover plate and handles. Two handles are fixedly connected to the cover plate. A through hole is provided at the center of the cover plate, and a connecting rod is located in the through hole.

[0006] The diameter of the cover plate is larger than the inner diameter of the bottom end of the positioning ring and smaller than the inner diameter of the top end of the positioning ring.

[0007] The positioning plate is a cross structure, formed by two mutually perpendicular flat plates fixedly connected.

[0008] A method for using a cover plate tooling for pouring a drainage hole of a T-beam, the method comprising: clamping the lower end of the cover plate tooling in the drainage hole through a positioning plate at the bottom end, applying a release agent around the outer side of a conical positioning ring, covering the positioning ring with a cover plate assembly, pouring concrete, and after the protective layer concrete is initially solidified, lifting the cover plate assembly, and injecting a foam filler into the gap between the positioning ring and the concrete from the gap of the cross plate; after the foam filler is solidified, the cover plate tooling can be separated from the protective layer concrete and recycled.

[0009] The beneficial effects of the present invention are as follows: compared with the prior art, the technical solution of the present invention is adopted, and the tooling design is light and one person can install all the tooling required for construction. It is also convenient to dismantle after construction, and can be recycled for many times, with high comprehensive economic benefits. A movable cover plate is provided in the conical positioning ring, which is convenient for injecting foam filler at the bottom of the conical positioning ring after the tooling is installed to prevent concrete leakage from contaminating the inside of the drain hole. The movable cover plate can prevent concrete from leaking into the drain hole and causing pollution. The tooling positioning ring adopts an inverted cone design to ensure that the appearance is neat and the external dimensions meet the design requirements, and it is convenient to disassemble and assemble the mold, improve productivity, reduce the labor intensity of workers, and achieve good on-site use effects.

[0015] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings of this specification.

[0016] Embodiment 1: As attached Figures 1 to 5 As shown, a cover plate tooling for pouring water drainage holes of T-beams comprises a positioning plate 4, a positioning ring 3 and a cover plate assembly 2. The positioning ring 3 is a conical cylinder structure which is larger at the top and smaller at the bottom. A cross plate 5 is fixedly connected to the inner side of the bottom end of the positioning ring 3. The positioning plate 4 is fixedly connected to the bottom end of the cross plate 5. A connecting rod 6 is vertically fixedly connected to the center of the cross plate 5. A handle 1 is fixedly connected to the top end of the connecting rod 6. The cover plate assembly 2 is movably sleeved on the connecting rod 6.

[0017] Furthermore, the cover plate assembly 2 includes a cover plate 22 and handles 21 . Two handles 21 are fixedly connected to the cover plate 22 . A through hole 23 is provided at the center of the cover plate 22 , and the connecting rod 6 is located in the through hole 23 .

[0018] Furthermore, the diameter of the cover plate 22 is larger than the inner diameter of the bottom end of the positioning ring 3 and smaller than the inner diameter of the top end of the positioning ring 3. The cover plate 22 is located in the positioning ring 3, which can protect the drain hole from being blocked by the poured concrete.

[0019] Furthermore, the positioning plate 4 is a cross structure, which is formed by two mutually perpendicular flat plates fixedly connected. The outer diameter of the positioning plate 4 is just matched with the inner diameter of the drain hole, so that the tool can be positioned in the drain hole without shaking, which facilitates the pouring of concrete to form better and meet quality requirements.

[0020] The tool is fixed in the middle of the drain hole by a cross-shaped positioning plate 4 so that it does not shake left and right and remains in a vertical state, so that the outer appearance and size of the protective layer above the drain hole meet the design requirements.

[0021] A method for using a cover plate tooling for pouring a drainage hole of a T-beam, the method comprising: clamping the lower end of the cover plate tooling in the drainage hole through a positioning plate 4 at the bottom end, applying a release agent around the outer side of a conical positioning ring 3, covering the positioning ring 3 with a cover plate assembly 2, pouring concrete, and after the protective layer of concrete has initially solidified, lifting the cover plate assembly 2, and injecting a foam filler into the gap between the positioning ring 3 and the concrete through the gap of a cross plate 5; after the foam filler has solidified, the cover plate tooling can be detached from the protective layer of concrete and recycled.

[0022] When in use, the cross-shaped positioning plate 4 at the lower end of the tool is stuck in the drain hole, and a release agent is applied around the conical positioning ring 3. After the protective layer concrete is initially set, the tool can be normally separated from the protective layer and recycled. After installation, the movable cover plate assembly 2 can be lifted to inject foam filler into the bottom of the conical positioning ring 3. After the protective layer concrete is initially set, the tool can be removed.

[0023] The parts not described in detail in the present invention are all known technologies to those skilled in the art. Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should be included in the scope of the claims of the present invention.
