Description

Technical Field

[0001] The utility model belongs to the field of water conservancy construction, and specifically relates to a separated inner formwork stand for construction of a back-casting belt of a beam-type U-shaped aqueduct. Background Art

[0002] The cast-in-place or prefabricated hoisting beam U-shaped aqueduct body of water conservancy projects has a post-casting strip between two adjacent trough bodies. The inner mold and formwork support used for the concrete construction of the post-casting strip of the U-shaped trough body are indispensable construction facility equipment.

[0003] In the existing formwork support system for the construction of the post-casting strip between two adjacent trough bodies of the beam-type U-shaped aqueduct, the inner and outer formworks are basically fixed by tension screws.

[0004] After the concrete construction of the backcast strip is completed, the tension screws and formwork are removed to form a through-hole in the backcast strip of the U-shaped aqueduct body. Dry hard mortar is often used to seal the tension screw holes, which affects the overall consistent performance of the U-shaped aqueduct and poses a hidden danger of water leakage.

[0005] The overall height of the large beam-type U-shaped aqueduct is relatively high. The construction of the post-casting strip requires the construction of a construction support inside the U-shaped aqueduct body for the construction of the post-casting strip of the U-shaped aqueduct body. Since it is necessary to set up a construction support, install formwork and tension screws in the post-casting strip between each adjacent U-shaped aqueduct body, the construction support platform is frequently erected and dismantled, which is time-consuming and labor-intensive, thus affecting the construction efficiency.

[0006] Therefore, we propose a separate inner formwork stand for the construction of the back-casting strip of the beam-type U-shaped aqueduct to solve the above problems. Utility Model Content

[0007] In view of the problems existing in the above-mentioned technology, the utility model provides a separate inner formwork stand for constructing the back-casting strip of a beam-type U-shaped aqueduct.

[0008] The utility model solves the technical problem by adopting a solution: a separate inner mold stand for the construction of the post-casting strip of a beam-type U-shaped aqueduct, comprising a walking frame, a template support system, and an inner mold for the post-casting strip of a U-shaped trough body made according to the width and structural characteristics of the post-casting strip between two adjacent U-shaped aqueduct bodies under construction;

[0009] The walking frame includes two layers of construction platforms arranged in parallel up and down, and a plurality of support rods are installed between the two layers of construction platforms;

[0010] The bottom of the construction platform of the lower layer is equipped with four supporting legs, and the bottom of the supporting legs is equipped with bottom walking wheels;

[0011] The formwork support system includes a middle rectangular frame, which is mounted on the outside of the two-layer construction platform so that the middle rectangular frame can move with the walking frame;

[0012] A plurality of bidirectional adjustment tie rods are installed around the central rectangular frame and between the inner mold of the post-casting belt of the U-shaped trough body.

[0013] Preferably, guardrails are installed on the front and rear sides of the construction platform respectively.

[0014] Preferably, a diagonal brace is installed between the support foot and the lower construction platform.

[0015] Preferably, a plurality of side walking wheels are respectively installed on the left and right sides of the construction platform.

[0016] Preferably, the inner mold of the post-casting strip of the U-shaped trough body includes a top mold, a bottom mold and two sets of side molds, the side molds and the bottom molds are detachably connected by a mold hinge, and the side molds and the top molds are detachably connected by a mold hinge.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. The utility model installs a plurality of bidirectional adjustment tie rods between the middle rectangular frame and the inner mold of the U-shaped trough body post-casting strip, thereby realizing the accurate installation and fixation of the inner mold of the U-shaped trough body post-casting strip at the position of the post-casting strip between two adjacent U-shaped aqueduct bodies, solving the problem that the construction method of setting the inner mold with tension screws to fix the tension screws leads to the existence of through holes in the post-casting strip of the U-shaped aqueduct body, thereby improving the overall consistency performance and overall strength of the construction body of the U-shaped aqueduct.

[0019] 2. The walking frame and formwork support system of the utility model can be separated from the inner mold of the post-casting strip of the U-shaped trough body. The walking frame and the formwork support system can move forward and backward in the U-shaped aqueduct and can be used as a construction support work platform alone, and can be used for the reinforcement binding of the post-casting strip of the U-shaped aqueduct trough or the trough body inspection, etc. After the construction of one place is completed, it can be quickly moved to the next construction point, which greatly improves the construction efficiency.

[0020] 3. The utility model allows workers to install two-way adjustable pull rods and remove the inner mold of the U-shaped trough post-casting belt on a construction platform with guardrails, which provides stable and safe working facilities, improves work efficiency and safety, shortens working time and saves construction costs.
