Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, specifically to tunnel sidewall support formwork. Background Technology

[0002] During tunnel construction, tunnel sidewall support formwork is needed to support the tunnel sidewalls and keep them safe and stable.

[0003] In existing technologies, the supporting formwork is generally composed of a formwork frame, back ribs, transverse ribs, support legs, embedded parts, etc. In use, the formwork frame and other structures are connected by bolts to support the tunnel sidewall.

[0004] However, in actual use, because one of the embedded parts is designed at an angle, it needs to be slid from bottom to top during installation and then installed with bolts. This process makes it difficult to match the embedded part with the holes on the formwork. Furthermore, when pouring concrete, some concrete will enter the bolt holes inside the embedded part, making it impossible to install the bolts inside the embedded part. This makes the operation more complicated for workers, causing great inconvenience and affecting the construction progress. Utility Model Content

[0005] The purpose of this utility model is to provide a tunnel sidewall support template to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tunnel sidewall support template, including a template frame, an embedded part inserted inside the template frame, an insert block inserted on the upper side of the embedded part, a cover plate fixedly connected to the top of the insert block, and multiple protrusions fixedly connected to the outer periphery of the insert block. A groove is opened inside the embedded part, and the protrusions fit into the groove.

[0007] Preferably, the insert has multiple mounting slots inside, a pull rope is slidably connected inside the mounting slots, an elastic element is sleeved on the outside of the pull rope, a limit block is fixedly connected to one end of the pull rope, a push rod is fixedly connected to the other end of the limit block, a push plate is fixedly connected to the end of the push rod away from the limit block, and multiple limit slots are formed on the outer side of the insert.

[0008] Preferably, the outer periphery of the cover plate is provided with a sliding groove, and a sliding ring is slidably connected inside the sliding groove, with the other end of the pull rope fixedly connected to the bottom end of the sliding ring.

[0009] Preferably, the bottom end of the cover plate is fitted with the top end of the embedded part.

[0010] Preferably, one end of the elastic element is fixedly connected to the inner wall of the mounting groove, and the other end of the elastic element is fixedly connected to the limiting block.

[0011] Preferably, the limiting block is slidably connected inside the mounting groove, one side of the push rod is slidably connected inside the mounting groove, the other side of the push rod is slidably connected inside the limiting groove, and the push plate is slidably connected inside the limiting groove.

[0012] Preferably, the upper side of the pull rope is slidably connected to the inside of the cover plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The tunnel sidewall support formwork proposed in this utility model can block the bolt holes by inserting a block and a cover plate inside the threaded holes, so that the poured concrete will not enter the bolt holes.

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1: Please refer to Figures 1 to 6 This utility model provides a technical solution: a tunnel sidewall support template, including a template frame 1. An embedded part 2 is inserted into the inside of the template frame 1. An insert block 3 is inserted into the upper side of the embedded part 2. A cover plate 4 is fixedly connected to the top of the insert block 3. The bottom end of the cover plate 4 fits against the top end of the embedded part 2 and is used in conjunction with the insert block 3 to block the bolt holes inside the embedded part 2. Multiple protrusions 5 are fixedly connected to the outer periphery of the insert block 3. A groove 6 is opened inside the embedded part 2. The protrusions 5 fit against the groove 6, so that the connection between the insert block 3 and the embedded part 2 is relatively stable.

[0024] When it is necessary to plug the bolt holes inside the embedded part 2, the insert block 3 is inserted into the embedded part 2, and the cover plate 4 is attached to the upper side of the embedded part 2, so that the protrusion 5 is attached to the inside of the groove 6. This makes the connection between the insert block 3 and the embedded part 2 more stable, so that the insert block 3 will not automatically detach from the embedded part 2. Conversely, when it is necessary to remove the insert block 3, the cover plate 4 is pulled upward, so that the cover plate 4 pulls the insert block 3 out of the embedded part 2, so that the protrusion 5 is detached from the inside of the groove 6. This exposes the bolt holes inside the embedded part 2, at which point the bolts can be installed, so that the embedded part 2 can be conveniently installed on the formwork 1, thereby speeding up the construction progress and reducing the installation time.

[0025] Example 2: Based on Example 1, to achieve more stable installation of the insert 3, multiple mounting slots 10 are provided inside the insert 3. A pull rope 9 is slidably connected inside the mounting slot 10, and the mounting slot 10 limits the pull rope 9, allowing it to slide smoothly. An elastic element 11 is sleeved on the outside of the pull rope 9. One end of the pull rope 9 is fixedly connected to a limiting block 12. One end of the elastic element 11 is fixedly connected to the inner wall of the mounting slot 10, and the other end is fixedly connected to the limiting block 12. The limiting block 12 is slidably connected inside the mounting slot 10, and the mounting slot 10 limits the limiting block 12, preventing the mounting slot 10 from moving. The push rod 13 is fixedly connected to the other end of the limiting block 12. One side of the push rod 13 is slidably connected to the inside of the mounting groove 10. The mounting groove 10 limits the push rod 13, allowing it to slide smoothly. The end of the push rod 13 away from the limiting block 12 is fixedly connected to the push plate 14. Multiple limiting grooves 15 are opened on the inner and outer sides of the insert block 3. The other side of the push rod 13 is slidably connected to the inside of the limiting groove 15. The limiting groove 15 limits the push rod 13, allowing it to slide smoothly. The push plate 14 is slidably connected to the inside of the limiting groove 15. The limiting groove 15 limits the push plate 14, preventing it from shifting when moving.

[0026] When the insert 3 needs to be inserted into the embedded part 2, the pull rope 9 is pulled upwards, causing the pull rope 9 to pull the limiting block 12 to move inwards. This causes the limiting block 12 to compress the elastic element 11 and deform. As a result, the limiting block 12 can pull the push plate 14 to move inwards via the push rod 13. After the insert 3 is inserted into the embedded part 2, the pull rope 9 is released, causing the elastic element 11 to reset. This causes the elastic element 11 to push the limiting block 12 to slide outwards. The limiting block 12 can then push the push plate 14 to slide outwards via the push rod 13. This causes the push plate 14 to compress the inner wall of the insert 3, causing the insert 3 to deform. This allows the insert 3 to be stably connected to the inside of the embedded part 2.

[0027] Example 3: Based on Example 2, in order to facilitate the pulling of the pull rope 9, a groove 7 is provided on the outer periphery of the cover plate 4. A slip ring 8 is slidably connected inside the groove 7. The groove 7 limits the slip ring 8 so that the slip ring 8 will not deviate when sliding. The other end of the pull rope 9 is fixedly connected to the bottom end of the slip ring 8, so that the slip ring 8 can easily pull the pull rope 9. The upper side of the pull rope 9 is slidably connected inside the cover plate 4. The cover plate 4 limits the pull rope 9 so that the pull rope 9 can slide more smoothly.

[0028] When it is necessary to pull the rope 9, the slip ring 8 is pulled upward, so that the slip ring 8 slides against the groove 7, thereby pulling the rope 9 upward.

[0029] In actual use, by pulling the slip ring 8 upward, it slides against the groove 7, causing the slip ring 8 to pull the pull rope 9 upward. This pull rope 9 then pulls the limiting block 12 inward, causing the limiting block 12 to compress the elastic element 11 and deform. The limiting block 12 then pulls the push plate 14 inward via the push rod 13, inserting the insert 3 into the embedded part 2 and causing the cover plate 4 to fit against the upper side of the embedded part 2. This releases the pull rope 9, allowing the elastic element 11 to reset and push the limiting block 12 outward, causing the limiting block... 12 can push the push plate 14 outward through the push rod 13, thereby causing the push plate 14 to press the inner wall of the insert 3, causing the insert 3 to deform, so that the protrusion 5 can fit into the inside of the groove 6, thereby making the connection between the insert 3 and the embedded part 2 more stable, so that the insert 3 will not automatically detach from the embedded part 2. On the contrary, pull the slip ring 8 upward and reverse the above operation, so that the insert 3 can detach from the embedded part 2, thereby exposing the bolt holes inside the embedded part 2. At this time, the bolts can be installed, so that the embedded part 2 can be conveniently installed on the formwork 1, thereby speeding up the construction progress and reducing the installation time.
