Description

Technical Field

[0001] This utility model relates to the field of template technology, specifically a template for river embankment construction. Background Technology

[0002] In the construction of river embankments, retaining formwork is an indispensable piece of equipment. Its main function is to provide a forming space for concrete pouring, ensuring the construction quality and structural shape of the river embankment. Currently, most existing retaining formwork for river embankments requires a large number of bolts, nuts and other connectors for fixing during splicing. During the splicing process, workers need to repeatedly align the holes and tighten the bolts, which is cumbersome and not only consumes a lot of manpower and time, but also easily leads to excessive gaps in the formwork splicing due to uneven bolt tightening, affecting the quality of concrete pouring and making it difficult to meet the needs of rapid river embankment construction. Utility Model Content

[0003] The purpose of this utility model is to provide a template for river embankment construction, which has the advantages of quick splicing and firm assembly.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a river embankment retaining wall casting template, comprising a first template, an internal locking block installed on the right side of the first template, a second template installed on the right side of the internal locking block, a locking groove for the internal locking block to be inserted on the left side of the second template, a lower connecting block and an upper connecting block respectively installed at the upper and lower ends of the right side of the first template, a receiving groove for the lower connecting block to be installed at the lower end of the left side of the second template, a positioning groove at the upper end of the left side of the second template, a positioning bracket installed on the right side of the top of the first template, support springs symmetrically installed at the bottom of the right end of the positioning bracket, a lifting plate installed at the lower end of the support spring, a positioning locking block installed at the bottom of the lifting plate, and vertically arranged slots inside the upper connecting block and the positioning groove.

[0005] As a preferred embodiment, limit baffles are installed on both the front and rear sides of the right end of the first template, and the distance between the two limit baffles is the same as the thickness of the second template. An external locking block is installed on the right side of the second template.

[0006] As a preferred embodiment, a tension rod is fixedly installed on the top of the lifting plate, and the upper end of the tension rod extends through to the top of the positioning bracket where a pull plate is installed. The lower end of the positioning block corresponds to the slot inside the upper connecting block.

[0007] As a preferred embodiment, the upper end of the tension rod is provided with a positioning slot, and a positioning insert rod is longitudinally engaged inside the positioning slot, the positioning insert rod being L-shaped.

[0008] As a preferred embodiment, a positioning connecting frame is installed between the front sides of the first template and the second template by screws. An adjusting rod is vertically slidably installed inside the left end of the positioning connecting frame, and the back side of the adjusting rod is connected to the front side of the first template.

[0009] As a preferred embodiment, positioning brackets are installed on both the upper and lower sides of the left end of the first template, and the positioning brackets are generally arranged in a semi-rectangular shape.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model achieves rapid template fixing without the need for a large number of bolts by using a built-in locking block and locking groove, and a lower connecting block and receiving groove for initial positioning and cooperation. Combined with the support spring driving the positioning locking block to automatically insert into the slot of the upper connecting block and positioning groove, the template can be quickly fixed without the need for a large number of bolts, which greatly shortens the splicing time. At the same time, the limiting baffle can prevent the template from shifting back and forth during splicing. The positioning connecting frame and the adjustable adjustment rod further enhance the overall stability after splicing, avoiding template deformation and displacement during concrete pouring. The overall design takes into account rapid splicing, stability and reliability, convenient operation and practical adaptability, effectively improving the efficiency and quality of river embankment construction.

[0011] 2. This utility model ensures that the lower end of the positioning block precisely aligns with the internal slot of the upper connecting block. Combined with the elasticity of the support spring, this ensures that the positioning block is stably inserted into the slot, thus fixing the upper part of the first template and the second template. The tension rod and pull plate provide convenient operation points for disassembly. Disassembly does not require complicated tools; the operator only needs to pull the pull plate upwards to raise the lifting plate and positioning block via the tension rod, causing the positioning block to disengage from the slot and quickly separating the two templates. When adjusting the position of the positioning block before splicing, inserting the positioning rod into the positioning slot of the tension rod can stably fix the position of the tension rod and the lifting plate, avoiding the need for the operator to continuously lift and pull the pull plate, greatly reducing the operational intensity and making the splicing process more labor-saving.

[0014] 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.

[0015] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0016] Example 1: Please see Figure 1 As shown, this utility model provides a formwork for pouring concrete for river embankment protection, including a first formwork 1. A built-in locking block 2 is installed on the right side of the first formwork 1, and a second formwork 3 is installed on the right side of the built-in locking block 2. A locking groove 4 for inserting the built-in locking block 2 is opened on the left side of the second formwork 3. A lower connecting block 8 and an upper connecting block 9 are respectively installed at the upper and lower ends of the right side of the first formwork 1. A receiving groove for installing the lower connecting block 8 is opened at the lower end of the left side of the second formwork 3. A positioning groove 10 is opened at the upper end of the left side of the second formwork 3. A positioning bracket 11 is installed on the right side of the top of the first formwork 1. A support spring 12 is symmetrically installed at the bottom of the right end of the positioning bracket 11. A lifting plate 13 is installed at the lower end of the support spring 12. A positioning locking block 14 is installed at the bottom of the lifting plate 13. Vertical slots are opened inside the upper connecting block 9 and the positioning groove 10.

[0017] This technical solution utilizes the initial positioning and engagement of the built-in locking block 2 and locking groove 4, and the lower connecting block 8 and receiving groove. Combined with the support spring 12 driving the positioning locking block 14 to automatically insert into the slot of the upper connecting block 9 and positioning groove 10, the template can be quickly fixed without a large number of bolts, significantly shortening the splicing time. At the same time, the limiting baffle 5 can prevent the template from shifting back and forth during splicing, and the positioning connecting frame 18 and the adjustable adjusting rod 19 further enhance the overall stability after splicing, avoiding template deformation and displacement during concrete pouring. The overall solution takes into account rapid splicing, stability and reliability, convenient operation and practical adaptability, effectively improving the efficiency and quality of river embankment construction.

[0018] Example 2: Based on Embodiment 1, this utility model is as follows: Figure 3 As shown, the first template 1 has limit baffles 5 installed on both the front and rear sides of the right end, and the distance between the two limit baffles 5 is the same as the thickness of the second template 3. An external card block 6 is installed on the right side of the second template 3.

[0019] Adopting such Figure 1 The technical solution shown has a channel formed by two limiting baffles 5 that is perfectly matched with the thickness of the second template 3. When the first template 1 and the second template 3 are spliced, the second template 3 can be accurately embedded between the limiting baffles 5, effectively preventing the second template 3 from shifting back and forth during the splicing process. This ensures that the built-in card block 2 and the card slot 4, the lower connecting block 8 and the receiving slot, and the upper connecting block 9 and the positioning slot 10 can be quickly aligned, greatly reducing the difficulty of alignment operations and improving splicing efficiency.

[0020] Secondly, in the technical solution, a tension rod 15 is fixedly installed on the top of the lifting plate 13. The upper end of the tension rod 15 extends through to the top of the positioning bracket 11 and a pull plate 16 is installed there. The lower end of the positioning block 14 corresponds to the slot inside the upper connecting block 9. A positioning slot is opened inside the upper end of the tension rod 15, and a positioning insert rod 17 is longitudinally engaged inside the positioning slot. The positioning insert rod 17 is L-shaped.

[0021] Its adoption is as follows Figure 1The technical solution shown has a precise alignment between the lower end of the positioning block 14 and the internal slot of the upper connecting block 9. Combined with the elastic force of the support spring 12, this ensures that the positioning block 14 is stably inserted into the slot, completing the fixation of the upper part of the first template 1 and the second template 3. The tension rod 15 and the pull plate 16 provide convenient operation points for disassembly. Disassembly does not require complicated tools. The operator only needs to pull the pull plate 16 upwards, which will drive the lifting plate 13 and the positioning block 14 to rise through the tension rod 15, so that the positioning block 14 is disengaged from the slot and the two templates are quickly separated. When adjusting the position of the positioning block 14 before splicing, the positioning rod 17 is inserted into the positioning slot of the tension rod 15, which can stably fix the position of the tension rod 15 and the lifting plate 13, avoiding the need for the operator to continuously lift the pull plate 16, greatly reducing the intensity of operation and making the splicing process more labor-saving.

[0022] Example 3: This utility model is as follows Figures 1-5 As shown, a positioning connecting bracket 18 is installed between the front sides of the first template 1 and the second template 3 by screws. An adjusting rod 19 is vertically slidably installed inside the left end of the positioning connecting bracket 18. The back of the adjusting rod 19 is connected to the front side of the first template 1. Positioning brackets 7 are installed on both the upper and lower sides of the left end of the first template 1. The positioning brackets 7 are generally semi-rectangular in shape.

[0023] Using the above technical solution, the positioning connecting frame 18 is installed on the front of the first template 1 and the second template 3 by screws. It can horizontally connect the two templates and make up for the deficiencies of the built-in card block 2, positioning card block 14 and other structures in frontal force protection. It prevents the template from deforming or misaligning on the front due to lateral pressure during concrete pouring. The vertical sliding cooperation between the adjusting rod 19 and the positioning connecting frame 18 can flexibly adapt to the slight height deviation that may occur when the two templates are spliced. There is no need to readjust the template position. Just slide the positioning connecting frame 18 vertically along the adjusting rod 19 to find a suitable fixed position and lock it with screws. This not only ensures the reinforcement effect of the positioning connecting frame 18, but also reduces the strict requirements on the template splicing accuracy and improves the operation error tolerance.

[0024] The working principle of this utility model is as follows: First, the worker places the first template 1 in the designated position, then pulls the pull plate 16 upwards. The lifting plate 13 and the positioning block 14 are raised through the tension rod 15. The positioning rod 17 is inserted into the positioning slot and placed on top of the positioning bracket 11 to fix the positioning block 14. Next, the snap-fit ​​groove 4 on the left side of the second template 3 is aligned with the built-in snap-fit ​​block 2. At the same time, the receiving groove on the left side of the second template 3 is aligned with the lower connecting block 8, and the positioning groove 10 is aligned with the upper connecting block 9. The second template 3 is pushed so that the built-in snap-fit ​​block 2 is inserted into the snap-fit ​​groove 4, the lower connecting block 8 is inserted into the receiving groove, and the upper connecting block 9 is inserted into the receiving groove. Inside the positioning groove 10, the positioning rod 17 is then pulled out. Under the elastic force of the support spring 12, the lifting plate 13 drives the positioning block 14 to descend, so that the positioning block 14 passes through the slot of the upper connecting block 9 and is inserted into the slot of the positioning groove 10, completing the initial splicing of the first template 1 and the second template 3. Finally, the position of the positioning connecting frame 18 is adjusted, and the right end of the positioning connecting frame 18 is fixedly connected to the front of the second template 3 by screws to further fix the template. When multiple templates need to be spliced, the snap-fit ​​groove 4 of the subsequent template is aligned with the outer snap-fit ​​block 6 of the previous template and the end is aligned with the positioning frame 7 for splicing, following the above steps.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
