Description

Technical Field

[0001] This utility model relates to the field of pipe gallery construction technology, specifically a prefabricated pipe gallery end template. Background Technology

[0002] In the construction of precast pipe galleries, a common method is to pre-leave installation grooves for waterproof adhesive strips at the ends of the galleries and then attach the waterproof adhesive strips to these grooves. This method requires processes such as grinding and cleaning the concrete interface, applying adhesive, and attaching the adhesive strips. The process is cumbersome, and gaps may remain between the adhesive strips and the concrete surface after attachment, potentially leading to water leakage in the pipe galleries later on. Summary of the Invention

[0003] This utility model provides a prefabricated pipe gallery end template. The purpose of this utility model is achieved through the following technical solution:

[0004] It consists of an end panel, a rubber strip storage slot, adjusting bolts, bolt holes, pressure blocks, and a pressure block storage slot.

[0005] The end panel is made of steel plate.

[0006] The width of the adhesive strip storage groove is slightly larger than the width of the waterproof adhesive strip by 2mm, and the depth is 50% of the thickness of the waterproof adhesive strip.

[0007] There are 3 adjusting bolts on each side, for a total of 12 bolts, which are screwed into the bolt holes.

[0008] The bolt hole size matches the adjusting bolt.

[0009] There is one pressure block on each side, for a total of four, which are placed in the pressure block storage slot.

[0010] The width of the storage groove for the pressed block is slightly greater than the thickness of the pressed block by 2mm, and the depth is the same as the height of the pressed block.

[0011] Place the waterproof strip in the strip storage slot, turn the adjusting bolt to press the waterproof strip tightly with the pressure block, and loosen the adjusting bolt to remove the formwork after the concrete has been poured and has reached the demolding strength.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] The terms “center,” “longitudinal,” “lateral,” “length,” “width,” “thickness,” “upper,” “lower,” “front,” “back,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” “outer,” “clockwise,” and “counterclockwise” indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience and simplification of description and do not imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this document.

[0018] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0019] like Figure 1 and Figure 2 As shown, this utility model provides a prefabricated pipe gallery end template, which includes an end panel 1, a rubber strip storage groove 2, an adjusting bolt 3, a bolt hole 4, a pressure block 5, and a pressure block storage groove 6.

[0020] The end panel 1 is made of steel plate. Specifically, the steel plate is 12mm thick.

[0021] The width of the adhesive strip storage groove 2 is slightly larger than the width of the waterproof adhesive strip by 2mm, and the depth is 50% of the thickness of the waterproof adhesive strip. Specifically, when the width of the waterproof adhesive strip is 40mm, the width of the adhesive strip storage groove 2 is 42mm, and when the height of the waterproof adhesive strip is 50mm, the depth of the adhesive strip storage groove 2 is 25mm.

[0022] There are 3 adjusting bolts 3 on each side, for a total of 12 bolts, which are screwed into bolt holes 4. Specifically, the diameter of the adjusting bolts 3 is 12mm.

[0023] The bolt hole 4 is sized to match the adjusting bolt 3. Specifically, the bolt hole 4 has a diameter of 12mm.

[0024] There are four pressure blocks 5, one on each side, which are placed in the pressure block storage slot 6. Specifically, the pressure blocks 5 are made of steel plate, with a thickness of 15mm and a height of 60mm.

[0025] The width of the briquette storage groove 6 is slightly greater than the thickness of the briquette by 2mm, and the depth is the same as the height of the briquette 5. Specifically, the width of the briquette storage groove 6 is 17mm and the depth is 60mm.

[0026] This utility model provides a prefabricated pipe gallery end template, the specific implementation of which includes the following steps:

[0027] Embed the waterproof adhesive strip into the adhesive strip storage slot 2, and firmly attach the joint of the adhesive strip with waterproof adhesive.

[0028] Rotate the adjusting bolt 3 to move the four-way pressure blocks 5 toward the adhesive strip storage slot 2 and press the waterproof adhesive strip.

[0029] After the concrete has been poured and has reached the required strength for demolding, loosen the adjusting bolts 3 to remove the formwork. Use a high-pressure water gun to clean the residual cement slurry on the formwork for future use.

[0030] The above description is merely a preferred embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this utility model should be included within the scope of protection of this utility model.
