Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering construction technology, specifically relating to a slope protection toothed wall formwork reinforcement construction structure. Background Technology

[0002] In slope construction for projects such as canal engineering and dam filling, the traditional method for constructing toothed walls involves installing formwork on top of the trench after excavation, based on positioning control lines. Holes are pre-drilled at corresponding positions on both sides of the formwork, and tie rods are used to connect the formwork on both sides. Square timber supports are placed in the middle of the formwork. In addition, a large number of square timber diagonal braces are usually required on the outside of the formwork to prevent the formwork from shifting during pouring. After the concrete is poured and initially set, the tie rods are removed and the holes of the tie rods are sealed. This process involves many steps, a large amount of work, and requires a lot of manpower and time. Moreover, since there are no stress points on both sides of the toothed wall, the reinforcement effect of the square timber diagonal braces is poor. Therefore, a new construction structure for reinforcing toothed wall formwork for slope protection should be provided. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a slope protection toothed wall formwork reinforcement construction structure to address the shortcomings of the prior art. The structure is simple and reasonably designed, which can maintain the overall structural balance and stability of the inner formwork, outer formwork and multiple portal tie rod reinforcement supports. During the concrete pouring process, the inner and outer formwork may deviate or tilt, which improves the reinforcement effect of the inner and outer formwork. It eliminates the need to seal the tie rod holes, greatly saves labor costs and improves construction efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a slope protection toothed wall formwork reinforcement construction structure, characterized in that: it includes a plurality of portal-shaped tie-down reinforcement brackets arranged at intervals along the length direction of the inner and outer formwork, the number of the portal-shaped tie-down reinforcement brackets being equal to the number of pre-embedded anchor piles and corresponding one-to-one, and a tie assembly or top support bracket being provided between the corresponding portal-shaped tie-down reinforcement bracket and the pre-embedded anchor pile, the plurality of tie assemblies and the plurality of top support brackets being arranged at intervals, the portal-shaped tie-down reinforcement bracket including an adjustable crossbeam, a first side plate and a second side plate respectively fixedly installed at both ends of the adjustable crossbeam, an adjustable positioning rod being provided between the first side plate and the second side plate, the first side plate and the second side plate being connected by a tie rod, the tie rod being located directly above the adjustable positioning rod, the first side plate being pressed against the outer surface of the inner formwork, and the second side plate being pressed against the outer surface of the outer formwork.

[0005] The above-mentioned slope protection toothed wall formwork reinforcement construction structure is characterized in that: the top support bracket includes a horizontal bar supporting the outer formwork and the pre-embedded anchor pile, an inclined bar supporting the second side plate and the pre-embedded anchor pile, and a reinforcing bar connecting the horizontal bar and the inclined bar.

[0006] The above-mentioned slope protection toothed wall formwork reinforcement construction structure is characterized in that: the tie assembly includes a fixing plate installed on the inner side of the second side plate and a U-shaped tie rod connected to the fixing plate. The U-shaped tie rod includes a U-shaped hook, two connecting rods respectively connected to the U-shaped hook, and a threaded rod connected to the connecting rod. The U-shaped hook is fitted on the pre-embedded anchor pile, and the two threaded rods are respectively locked to both ends of the fixing plate by locking nuts.

[0007] This utility model has the following advantages compared with the prior art:

[0008] 1. This utility model uses multiple portal-shaped tie rods for reinforcement. Each portal-shaped tie rod includes an adjustable crossbeam, a first side plate, a second side plate, an adjustable positioning rod, and tie rods. In actual use, the first side plate is pressed against the outer surface of the inner template, and the second side plate is pressed against the outer surface of the outer template. The adjustable positioning rod and tie rods are located above the inner and outer templates. The tie rods do not need to pass through the inner and outer templates. That is, after the concrete has initially set and the inner and outer templates have been removed, it is not necessary to seal the tie rod holes, which greatly saves labor costs and improves construction efficiency.

[0009] 2. This utility model sets up multiple pre-embedded anchor piles, and the number of portal-shaped tie-down reinforcement brackets is equal to the number of pre-embedded anchor piles, and they correspond one-to-one. By setting tie components or top supports between the corresponding portal-shaped tie-down reinforcement brackets and pre-embedded anchor piles, in actual use, the multiple pre-embedded anchor piles on the outside of the toothed wall can provide support points for the installation of tie components or top supports. When the multiple tie components and multiple top supports are arranged at intervals, the inner template, outer template and multiple portal-shaped tie-down reinforcement brackets can maintain the overall structural balance and stability. During the concrete pouring process, the inner template and outer template may deviate or tilt, thus improving the reinforcement effect of the inner template and outer template.

[0010] 3. This utility model has a simple structure, reasonable design, is easy to construct, and is easy to promote and apply.

[0011] In summary, this utility model has a simple structure and reasonable design, which enables the inner and outer formwork and multiple portal-shaped tie rod reinforcement supports to maintain the overall structural balance and stability. During the concrete pouring process, if the inner and outer formworks become misaligned or tilted, the reinforcement effect of the inner and outer formworks is improved. It eliminates the need to seal the tie rod holes, greatly saving labor costs and improving construction efficiency.

[0023] like Figure 1 , Figure 2 and Figure 3As shown, this utility model includes multiple portal-shaped tie-down reinforcement brackets arranged at intervals along the length direction of the inner template 4-1 and the outer template 4-2. The number of portal-shaped tie-down reinforcement brackets is equal to the number of pre-embedded anchor piles 5 and corresponds one-to-one. A tie assembly or top support bracket is provided between the corresponding portal-shaped tie-down reinforcement bracket and the pre-embedded anchor pile 5. Multiple tie assemblies and multiple top support brackets are arranged at intervals. The portal-shaped tie-down reinforcement bracket includes an adjustable crossbeam 1-1, a first side plate 1-2 and a second side plate 1-3 respectively fixedly installed at both ends of the adjustable crossbeam 1-1, and an adjustable positioning rod 2 is provided between the first side plate 1-2 and the second side plate 1-3. The first side plate 1-2 and the second side plate 1-3 are connected by a tie rod 3. The tie rod 3 is located directly above the adjustable positioning rod 2. The first side plate 1-2 is pressed against the outer surface of the inner template 4-1, and the second side plate 1-3 is pressed against the outer surface of the outer template 4-2.

[0024] In this embodiment, multiple portal-shaped tie rods are installed, each including an adjustable crossbeam 1-1, a first side plate 1-2, a second side plate 1-3, an adjustable positioning rod 2, and tie rods 3. In actual use, the first side plate 1-2 is pressed against the outer surface of the inner template 4-1, and the second side plate 1-3 is pressed against the outer surface of the outer template 4-2. The adjustable positioning rod 2 and tie rods 3 are both located above the inner template 4-1 and the outer template 4-2. The tie rods 3 do not need to pass through the inner template 4-1 and the outer template 4-2. That is, after the concrete has initially set, after removing the inner template 4-1 and the outer template 4-2, it is not necessary to seal the tie rod holes, which greatly saves labor costs and improves construction efficiency.

[0025] In this embodiment, multiple pre-embedded anchor piles 5 are set, and the number of portal-shaped tie-down reinforcement brackets is equal to the number of pre-embedded anchor piles 5, and they correspond one-to-one. By setting tie components or top supports between the corresponding portal-shaped tie-down reinforcement brackets and pre-embedded anchor piles 5, in actual use, multiple pre-embedded anchor piles 5 can provide support points for the installation of tie components or top supports on the outside of the toothed wall. When multiple tie components and multiple top supports are arranged at intervals, the inner template 4-1, the outer template 4-2 and multiple portal-shaped tie-down reinforcement brackets can maintain the overall structural balance and stability. During the concrete pouring process, the inner template 4-1 and the outer template 4-2 may deviate or tilt, which improves the reinforcement effect of the inner template 4-1 and the outer template 4-2.

[0026] In this embodiment, the lengths of both the adjustable crossbeam 1-1 and the adjustable positioning rod 2 are adjustable. The adjustable crossbeam 1-1 includes a main crossbeam and an auxiliary crossbeam inserted into the main crossbeam. Both the main crossbeam and the auxiliary crossbeam have four equally spaced fastening bolt mounting holes. In actual use, it is only necessary to adjust the depth of the auxiliary crossbeam into the main crossbeam according to the width specifications of the slope protection toothed wall to be formed, and select the corresponding fastening bolt mounting holes for fastening bolt installation to achieve the purpose of adjusting the length of the adjustable crossbeam 1-1. The adjustable positioning rod 2 includes a main positioning rod and an auxiliary positioning rod inserted into the main positioning rod. The auxiliary positioning rod inside the main positioning rod has two set screw mounting holes. In actual use, it is only necessary to adjust the depth of the auxiliary positioning rod into the main positioning rod according to the width specification of the slope protection toothed wall to be formed. Then, the set screw is installed in the set screw mounting hole to achieve the purpose of adjusting the length of the adjustable positioning rod 2. By adjusting the length of the adjustable beam 1-1 and the adjustable positioning rod 2, the application range of the portal tension reinforcement bracket can be broadened. It can be applied to the formwork reinforcement of slope protection toothed walls with different width requirements. It has a high reusability, good economy, and is easy to promote and apply.

[0027] like Figure 2 As shown, in this embodiment, the top support bracket includes a horizontal rod 6-2 supporting the outer template 4-2 and the pre-embedded anchor pile 5, an inclined rod 6-1 supporting the second side plate 1-3 and the pre-embedded anchor pile 5, and a reinforcing rod 6-3 connecting the horizontal rod 6-2 and the inclined rod 6-1.

[0028] like Figure 3 and Figure 4 As shown, in this embodiment, the tie assembly includes a fixing plate 8 installed on the inner side of the second side plate 1-3 and a U-shaped tie rod connected to the fixing plate 8. The U-shaped tie rod includes a U-shaped hook 7-1, two connecting rods 7-2 respectively connected to the U-shaped hook 7-1, and a threaded rod 7-3 connected to the connecting rod 7-2. The U-shaped hook 7-1 is fitted onto the pre-embedded anchor pile 5, and the two threaded rods 7-3 are respectively locked to both ends of the fixing plate 8 by locking nuts.

[0029] like Figures 1 to 4 As shown, during actual construction, firstly, multiple inner formwork 4-1 and multiple outer formwork 4-2 are erected sequentially; secondly, multiple pre-embedded anchor piles 5 are set on one side of the outer formwork 4-2; then, multiple portal-shaped tie rods are installed sequentially on the inner formwork 4-1 and the outer formwork 4-2, so that the multiple portal-shaped tie rods correspond one-to-one with the multiple pre-embedded anchor piles 5; then, tie components or top supports are installed between the corresponding portal-shaped tie rods and the pre-embedded anchor piles 5, and the multiple tie components and the multiple top supports are arranged at intervals; finally, concrete can be poured on site to form the slope protection tooth wall.

[0030] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
