Description

Technical Field

[0001] The utility model belongs to the field of building construction, and in particular relates to a copper water stop belt fixing device for a U-shaped aqueduct body. Background Art

[0002] Large-scale aqueduct structures are an important part of water diversion projects. Post-cast strips need to be reserved between multi-span cast-in-place large-scale U-shaped prestressed thin-walled trough bodies, and the structure must be waterproof and leak-proof.

[0003] In order to meet the requirements of the above standards, the U-shaped prestressed thin-walled trough body is equipped with copper waterstop and other anti-seepage measures. 1 / 2 of the width of the copper waterstop is buried in the trough structure concrete, and the other 1 / 2 is buried in the post-cast strip. In order to achieve the anti-seepage effect, the copper waterstop is generally embedded 15 cm away from the inner wall of the U-shaped trough, and requires precise positioning, smoothness, no wrinkles, and no damage.

[0004] Before pouring the trough concrete, the copper waterstop is first installed and fixed on the U-shaped trough end mold. Since the copper waterstop is thin, it is very easy to be twisted during installation. Once the copper waterstop is wrinkled, it is difficult to restore it to smoothness.

[0005] Traditional fixing uses positioning steel bar clamps, which can easily cause the copper waterstop to be offset, not centered, twisted, not straight, or even wrinkled, resulting in quality defects and loss of waterproofing effect.

[0006] Therefore, we propose a U-shaped aqueduct body copper waterstop fixing device to solve the above problems. Utility Model Content

[0007] In view of the problem that traditional fixing method adopts positioning steel bar clamps, which easily causes the copper waterstop to be offset, misaligned, twisted, not straight or even wrinkled, has quality defects and loses its waterproof effect, the utility model provides a copper waterstop fixing device for the body of a U-shaped aqueduct.

[0008] The utility model solves the technical problem by adopting a solution: a copper water stop belt fixing device for a U-shaped aqueduct body, comprising an outer end mold for connecting with an outer mold of the aqueduct body and an inner end mold for connecting with an inner mold of the aqueduct body.

[0009] The outer end mold and the inner end mold are spliced ​​to match the end surface size of the U-shaped aqueduct;

[0012] Preferably, the outer end formwork is assembled by splicing multiple outer formwork units according to the shape of the U-shaped aqueduct body, and the inner end formwork is assembled by splicing multiple inner formwork units according to the shape of the U-shaped aqueduct body.

[0013] Preferably, multiple rib plates are respectively arranged on the outer formwork units and the inner formwork units.

[0014] Preferably, a plurality of outer fixing holes are formed on the side of the outer formwork unit facing away from the rigid splint, and U-shaped buckles for connecting with the outer formwork of the aqueduct body are arranged in the outer fixing holes.

[0015] Preferably, a plurality of inner fixing holes are formed on the side of the inner formwork unit facing away from the rigid splint, and U-shaped buckles for connecting with the inner formwork of the aqueduct body are arranged in the inner fixing holes.

A cross beam formwork 14 is installed between the upper ends of the two sides of the inner end form 4. After the outer end form 3 and the inner end form 4 are spliced, they are adapted to the end face size of the trough body of the U-shaped aqueduct, improving the overall performance and overall strength of the device.

[0030] Steel splints 6 are respectively installed on the front sides of the outer end form 3 and the inner end form 4. Angle steels are welded between the steel splints 6 and the outer end form 3 or the inner end form 4.
