Description

Technical Field

[0001] This utility model relates to the field of formwork technology for civil engineering construction, specifically a concrete pouring formwork for water conservancy and hydropower civil engineering construction. Background Technology

[0002] In the field of water conservancy and hydropower civil engineering construction, concrete pouring is a crucial step, and the performance of the pouring formwork directly affects the quality and efficiency of concrete pouring. Currently, most concrete pouring formwork on the market is designed with a fixed height. This type of fixed-height formwork has many inconveniences in practical applications. Due to the diverse requirements for concrete pouring heights in different engineering projects and different construction parts of the same project, fixed-height formwork cannot meet the construction requirements when a higher concrete pouring height is needed. Construction workers have to use multi-layer formwork stacking, which is not only cumbersome and consumes a lot of manpower and time, increasing construction costs, but also makes it difficult to effectively guarantee the connection stability between the multiple layers of formwork. Problems such as loosening and displacement are prone to occur, which in turn affect the quality of concrete pouring, resulting in defects such as uneven surface and uneven strength of the poured structure, posing potential risks to the quality of the project.

[0003] Besides the height limitations, existing concrete pouring formwork also has significant shortcomings in sealing performance and reinforcement structure. In terms of sealing, many formwork joints are poorly designed and lack effective sealing measures, which makes it easy for cement slurry to leak out from the joints during concrete pouring. This not only wastes cement materials and increases project costs, but also forms hardened concrete on the outside of the formwork, affecting its reuse. At the same time, the leaked cement slurry will also pollute the construction site environment, making subsequent cleanup work difficult.

[0004] In terms of structural reinforcement, some formwork uses relatively simple reinforcement methods, resulting in limited strength and difficulty in withstanding the large lateral pressure generated during concrete pouring. During pouring, the formwork is prone to deformation and bulging due to excessive lateral pressure, severely affecting the shape and dimensional accuracy of concrete components, reducing project quality, and potentially causing formwork damage, leading to safety accidents and threatening the lives of construction workers. Therefore, we propose a concrete pouring formwork for water conservancy and hydropower civil engineering construction to address these problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a concrete pouring formwork for water conservancy and hydropower civil engineering construction, thereby solving the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a concrete pouring formwork for water conservancy and hydropower civil construction, including a lower formwork and an extension formwork. There may be multiple lower formworks and extension formworks, and the extension formwork is set on the upper part of the lower formwork. A first sealing plate is welded to one side wall and the top of the lower formwork. A second sealing plate is welded to one side wall and the top of the extension formwork. A first reinforcing plate is welded to one side of the lower formwork. A support frame is hinged to the first reinforcing plate. An installation fixing plate is hinged to the side of the support frame away from the first reinforcing plate. A second reinforcing plate is welded to one side of the extension formwork. Connecting angle steel is provided on the top of the two uppermost extension formworks that are in a parallel state.

[0007] As a preferred technical solution of this utility model, a sealing groove matching the first sealing plate is provided on the other side wall of the lower template, and multiple connecting through holes are provided on both sides of the lower template.

[0008] As a preferred technical solution of this utility model, a sealing groove matching the second sealing plate is provided on the other side wall of the heightened template, and a sealing groove matching the first sealing plate is provided at the bottom of the heightened template.

During the concrete pouring process, it can effectively prevent cement slurry from leaking out from the formwork joints, avoid the waste of cement materials, reduce the problem of concrete hardening on the outside of the formwork due to leakage, ensure the repeated use of the formwork, reduce the difficulty of cleaning the construction site, and maintain the cleanliness of the construction environment.

[0015] 3. This concrete pouring formwork for water conservancy and hydropower civil engineering construction features a support frame hinged to a first reinforcing plate welded to one side of the lower formwork. Multiple through holes are provided on an installation fixing plate hinged to the other side of the support frame.

A second reinforcing plate welded to one side of the raised formwork, along with connecting angle steels at the top of the two parallel raised formwork sections, are connected by bolts and nuts. This enhances the connection strength and overall stability between the raised formwork sections, enabling it to withstand the significant lateral pressure generated during concrete pouring. It effectively prevents formwork deformation and bulging, ensuring the shape and dimensional accuracy of the concrete components and improving project quality. Attached Figure Description

[0020] 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.

[0021] Example 1: Please refer to Figure 1 , Figure 2 and Figure 3A concrete pouring formwork for water conservancy and hydropower civil engineering construction includes a lower formwork 1 and a raised formwork 2. First, the number of lower formwork 1 and raised formwork 2 is determined according to the required concrete pouring height. The lower formwork 1 is placed in a predetermined position. Since the bottom of the lower formwork 1 is inclined, it further enhances the stability of the poured concrete. A support frame 4 is hinged to a first reinforcing plate 101 welded to one side of the lower formwork 1. Then, an installation fixing plate 401 is hinged to the side of the support frame 4 away from the first reinforcing plate 101. Through multiple installation through holes on the installation fixing plate 401, anchor bolts or similar materials can be used to firmly fix the installation fixing plate 401 to the ground of the construction site, thus providing stable support for the lower formwork 1. Next, the raised formwork 2 is placed on top of the lower formwork 1, so that the first sealing plate 101 welded to the top of the lower formwork 1... 2. Insert the first sealing plate 102 into the sealing groove at the bottom of the raised template 2, which matches the first sealing plate 102. Simultaneously, insert the second sealing plate 202 welded to one side wall of the raised template 2 into the sealing groove at the other side wall of the adjacent raised template 2, which matches the second sealing plate 202, to achieve a sealed splicing between the templates. Then, using the mounting holes at the top of the lower template 1 and the upper and lower parts of the raised template 2, use bolts and nuts to tightly connect the lower template 1 and the raised template 2. For the two uppermost raised templates 2 that are parallel, place connecting angle steel 3 on their tops. Use bolts and nuts to connect and fix the connecting angle steel 3 to the raised template 2 using multiple mounting holes on the connecting angle steel 3. If necessary, multiple connecting angle steels 3 can also be connected between the parallel raised templates 2 using bolts and nuts to enhance the stability of the overall structure. After the template assembly is completed, concrete pouring can begin.

[0022] Example 2: Please refer to Figure 1 , Figure 2 and Figure 3In another concrete pouring scenario of water conservancy and hydropower civil engineering construction, the same concrete pouring formwork is used. First, select an appropriate number of lower formwork 1 and extension formwork 2 according to the project requirements. Place the lower formwork 1 on the leveled and compacted construction site. Install the support frame 4 on the first reinforcing plate 101, and install the fixing plate 401 on the support frame 4. Use chemical anchors to fix the fixing plate 401 to the ground through the installation through holes to ensure the stability of the lower formwork 1. Alternatively, expansion bolts can be used to fix it to the pre-poured concrete foundation to make the lower formwork 1 stable. Then, the extension formwork is stacked one by one. 2. During the stacking process, ensure that the first sealing plate 102 of the lower template 1 is accurately inserted into the sealing groove at the bottom of the raised template 2, and that the second sealing plate 202 of the raised template 2 is inserted into the sealing groove on the side wall of the adjacent raised template 2 to prevent grout leakage during concrete pouring. Utilize the mounting holes on the lower template 1 and the raised template 2 to connect them with bolts and nuts. For the uppermost parallel raised template 2, install connecting angle steel 3. Through the mounting holes on the connecting angle steel 3, use bolts and nuts to tightly connect the connecting angle steel 3 to the raised template 2. As needed, arrange multiple connecting angle steels 3 between the raised templates 2 to enhance the template's resistance to lateral pressure. After the template installation is complete, concrete pouring is carried out. During the pouring process, the good sealing and reinforcement effect of the template effectively ensures the quality of the concrete pouring.

[0023] Implementation results: Multiple lower formwork 1 and raised formwork 2 can be set, and raised formwork 2 can be set on top of lower formwork 1. Construction workers can flexibly combine the number of lower formwork 1 and raised formwork 2 according to the actual needs of concrete pouring height for different projects. Unlike traditional formwork, which requires cumbersome modification or customization due to fixed height, this greatly improves the versatility and applicability of the formwork and effectively saves construction costs and time.

[0024] The first sealing plate 102 welded to one side wall and top of the lower template 1, and the second sealing plate 202 welded to one side wall and top of the raised template 2, precisely match the corresponding sealing grooves to form a tight sealing structure. During the concrete pouring process, this effectively prevents cement slurry from leaking out from the template joints, avoids waste of cement materials, reduces the problem of concrete hardening on the outside of the template due to leakage, ensures the template can be reused multiple times, reduces the difficulty of cleaning the construction site, and maintains a clean construction environment.

[0025] A support frame 4 is hinged to the first reinforcing plate 101 welded to one side of the lower template 1. The mounting plate 401, which is hinged to the other side of the support frame 4, has multiple mounting through holes. The mounting plate 401 can be firmly fixed to the construction site in various ways, providing reliable support for the lower template 1. The second reinforcing plate 201 welded to one side of the raised template 2 and the connecting angle steel 3 set at the top of the two uppermost raised templates 2 in a parallel state are connected by bolts and nuts, which enhances the connection strength and overall stability between the raised templates 2. It can withstand the large lateral pressure generated during concrete pouring, effectively prevent template deformation and bulging, ensure the shape and dimensional accuracy of the concrete components, and improve the quality of the project.
