Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a sliding formwork for reservoir step construction. Background Technology

[0002] With the increasing demand for water resource development and regulation, reservoir construction plays a crucial role in ensuring flood control, irrigation, water supply, and power generation. Reservoir step construction, as an important component of reservoir construction, directly affects the service life and operational safety of the water conservancy project. Sliding formwork has been widely used in reservoir step construction, efficiently completing the concrete pouring process and adapting to different terrains and design requirements. The application of this formwork not only improves construction efficiency but also enhances the appearance quality and stability of the concrete structure, demonstrating promising application prospects.

[0003] In the prior art, patent document CN220285322U, entitled "A Concrete Pouring Formwork Template," provides a technical solution. Its main features include equidistantly distributed step adjustment devices on the top of the stair support base plate, fixedly connected limiting devices, step partition plates set between the stair support base plates, and synchronous disassembly devices on both sides. The design intent of this structure is to achieve rapid assembly and convenient disassembly of stairs with different slope requirements, facilitating reuse. However, for cast-in-place reservoir steps, their length is typically long, and the prior art solution lacks a reinforcing structure in the middle of the slab. This easily leads to deformation of the slab after concrete pouring, resulting in uneven steps, dimensional deviations, and other problems, severely affecting the appearance quality of the reservoir steps and potentially threatening the structural stability.

[0004] Therefore, it is necessary to develop a sliding formwork with a central reinforcement structure that can adapt to the construction requirements of long reservoir steps, in order to address the shortcomings of existing technologies and ensure the quality and efficiency of reservoir projects. Utility Model Content

[0005] The present invention aims to provide a sliding formwork for reservoir step construction to overcome the shortcomings of the above-mentioned situation.

[0006] In order to achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A sliding formwork for reservoir step construction includes:

[0008] Two parallel and spaced-apart side panels;

[0009] A plurality of partition plates are located between the two side plates and arranged along the length of the side plates. The partition plates are arranged vertically, and a stepped pouring space is formed between adjacent partition plates. The lower ends of a plurality of support rods are fixedly connected to the side of the partition plate near the bottom of the slope along its length.

[0010] Multiple sets of reinforcing rods are arranged parallel to the side plate, and the multiple sets of reinforcing rods are spaced apart along the length of the partition plate. Each set of reinforcing rods is fixedly connected to the support rods on multiple partition plates, and the reinforcing rods on both sides are fixedly connected to the two side plates respectively.

[0011] Furthermore, each group of reinforcing rods consists of multiple rods, which are spaced apart vertically. Each reinforcing rod has multiple first strip holes that correspond one-to-one with the multiple support rods.

[0012] Furthermore, the multiple reinforcing rods in each group are arranged in parallel, and the first strip hole is arranged along the length direction of the reinforcing rod.

[0013] Furthermore, the reinforcing rods located on both sides below are provided with multiple second strip-shaped holes, and the top of the side plate is provided with multiple connecting holes. The multiple connecting holes are spaced apart along the length of the side plate, and the second bolt passes through the second strip-shaped holes and the connecting holes and is threaded with a second nut.

[0014] Furthermore, the second strip-shaped hole is provided along the length direction of the reinforcing rod.

[0015] Furthermore, a first reinforcing rib is fixedly provided on the side of the partition plate near the bottom of the slope, and the first reinforcing rib is fixedly connected to the support rod.

[0026] 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.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Reference Figure 1-3 This utility model provides a sliding formwork for reservoir step construction, which mainly consists of two side plates 1, multiple partition plates 2 and multiple sets of reinforcing rods 4.

[0029] Two side plates 1 are set parallel to each other and maintain a certain distance, serving a supporting role in the entire formwork structure and limiting the width of the poured steps. Their length, width, and thickness, among other dimensional parameters, need to be rationally designed and determined by comprehensively considering factors such as the actual specifications of the reservoir steps and the spatial conditions of the construction site. Side plates 1 are typically made of high-strength, corrosion-resistant steel to ensure good stability and durability in complex construction environments.

[0030] Between two side panels 1, multiple partition plates 2 are vertically arranged along the length of the side panels 1. The spaces between adjacent partition plates 2 form a space for pouring concrete for the steps, thus shaping the basic form of the reservoir steps. On the side of the partition plate 2 closest to the bottom of the slope, the lower ends of multiple support rods 3 are fixedly connected along its length. The support rods 3 are made of steel of suitable strength and are reliably fixed to the partition plates 2 by welding or bolting, providing reinforcement and support to the partition plates 2 and preventing deformation during concrete pouring, thereby ensuring the dimensional accuracy and appearance quality of the steps. Specifically, in this invention, the lower ends of the multiple support rods 3 are welded and fixed to the side of the partition plate 2 closest to the bottom of the slope.

[0031] The template also features multiple sets of reinforcing rods 4 parallel to the side panels 1, spaced apart along the length of the partition plates 2. Each set of reinforcing rods 4 is fixedly connected to multiple support rods 3 on the partition plates 2, while the reinforcing rods 4 on both sides are fixed to the corresponding side panels 1. The reinforcing rods 4 are also made of high-strength steel and are firmly connected to the support rods 3 and side panels 1 via welding or bolting, further strengthening and stabilizing the entire template structure, improving its load-bearing capacity and deformation resistance during construction, and ensuring the integrity and stability of the template.

[0032] It should be noted that this utility model is a method of on-site construction on the slope of a reservoir, because no bottom plate is set between the two side plates 1, which is located below the partition plate 2.

[0033] Each set of reinforcing rods 4 includes multiple reinforcing rods 4 spaced apart in the vertical direction, thereby improving the deformation resistance of the partition plate 2 and keeping it vertical. First slotted holes 5 are provided on the reinforcing rods 4, corresponding one-to-one with the multiple support rods 3. First bolts 6 pass through the first slotted holes 5 and the reinforcing rods 4, and a first nut 7 is threaded through to achieve a tight connection between the reinforcing rods 4 and the support rods 3. The design of the first slotted holes 5 facilitates adjustment of the relative positions between the reinforcing rods 4 and the support rods 3 during installation, improving installation flexibility and adaptability, and effectively addressing dimensional deviations in different construction scenarios.

[0034] Each group of multiple reinforcing rods 4 are parallel to each other, and the first strip hole 5 is set along the length of the reinforcing rod 4. This design layout can not only ensure the stability of the connection between the reinforcing rod 4 and the support rod 3, but also help to evenly distribute stress in the length direction, making the formwork structure more rationally stressed and better able to resist complex stress conditions such as lateral pressure generated during concrete pouring, thus ensuring the reliability and stability of the formwork construction process.

[0035] The reinforcing rods 4 located on both lower sides are provided with multiple second strip-shaped holes 8. Correspondingly, the top of the side plate 1 is provided with multiple connecting holes 9 spaced apart along the length direction. During installation, the second bolts 10 pass through the second strip-shaped holes 8 and the connecting holes 9, and are connected by threads to the second nuts, thus achieving a firm connection between the side plate 1 and the reinforcing rods 4. The second strip-shaped holes 8 are set along the length direction of the reinforcing rods 4, providing greater adjustment space for the connection between the side plate 1 and the reinforcing rods 4. The relative positions can be flexibly adjusted according to actual construction needs, making the formwork better adaptable to on-site construction conditions and the specific size requirements of the reservoir steps, thereby improving the versatility and operability of the formwork.

[0036] Optionally, a first reinforcing rib 12 is fixedly installed on the side of the partition plate 2 near the bottom of the slope and fixedly connected to the support rod 3 to enhance the structural strength and deformation resistance of the partition plate 2, ensure the stability and reliability of the partition plate 2 during the concrete pouring process, and help to form a flat and regular reservoir step.

[0037] Furthermore, a second reinforcing rib 13 is fixedly installed on the side of the two side plates 1 that are far apart from each other. The second reinforcing rib 13 is connected to a support leg 14 in the shape of a right angled triangle. One right-angled side of the support leg 14 is fixedly connected to the second reinforcing rib 13, and the other right-angled side is arranged horizontally and has mounting holes 15. This design of the support leg 14 provides stable support for the entire formwork structure, ensuring that the formwork remains stable during construction. At the same time, the mounting holes 15 allow for easy connection and fixation of the formwork to the ground or other fixed structures, enhancing the formwork's anti-overturning ability and stability. The right-angled triangle shape also helps to distribute and transfer the forces borne by the formwork, improving the overall stability and safety of the formwork structure.

[0038] In this invention, both the support rod 3 and the reinforcing rod 4 are made of angle steel. Angle steel has the advantages of low cost, easy processing, and high strength. It can meet the requirements of load-bearing capacity, stability, and durability during formwork construction, and is also easy to obtain from the market and for subsequent processing and manufacturing, which helps to reduce the cost of formwork manufacturing and construction.

[0039] Working principle of this utility model:

[0040] When using this sliding formwork for reservoir step construction, firstly, according to the design dimensions of the reservoir steps and the actual conditions of the construction site, place two side plates 1 parallel and at a certain distance to ensure accurate positioning and horizontal stability. Then, install multiple partition plates 2 vertically along the length of the side plates 1, and adjust the spacing of the partition plates 2 to form a step pouring space that meets the design requirements. Next, arrange multiple sets of reinforcing rods 4 at intervals along the length of the partition plates 2. Use the first bolt 6, the first nut 7, and the first slotted hole 5 to fix each set of reinforcing rods 4 to the support rods 3 on the multiple partition plates 2. At the same time, use the second bolt 10, the second nut, the second slotted hole 8, and the connecting hole 9 to firmly connect the reinforcing rods 4 on both sides to the side plates 1 on both sides, completing the formwork structure assembly.

[0041] After the template is assembled, it is reliably connected to the ground or other fixed structure through the mounting holes 15 on the support legs 14 to ensure the stability and safety of the template during concrete pouring. Then, the concrete pouring operation is carried out, and the concrete is filled into the step pouring space between adjacent partition plates 2. After pouring and vibration compaction, the reservoir step structure of the predetermined shape is formed.

[0042] Once the concrete has reached a certain strength, disconnect the support leg 14 from the ground or other fixed structure, remove the sliding formwork, and clean, inspect, and maintain it. Then, while maintaining the existing shape, move the formwork upwards to continue construction of the next step.

[0043] In one specific embodiment of this utility model, the reservoir slope concrete is 27m long, 75mm thick, and the steps are 3m wide and 16cm thick. It is constructed in 5m sections, poured in stages from the bottom to the top of the slope. Before the step construction, the slope concrete has been laid and the step construction area has been reserved. Support legs 14 are installed on the existing slope concrete. After the initial formwork is erected and the concrete has set, the formwork is moved upwards along the slope by sliding and fixed, and then the next stage of step construction is carried out. This process is then repeated.

[0044] Compared with the prior art, the present invention has the following advantages:

[0045] a. Structural reinforcement to ensure accuracy: By adding multiple support rods 3 and multiple sets of reinforcing rods 4, the problem of easy deformation due to lack of reinforcement structure in the middle of the plate in the existing technology is effectively solved. The support rods 3 connected to the side of the partition plate 2 near the bottom of the slope, and the multiple sets of reinforcing rods 4 fixed to the support rods 3, provide strong support for the partition plate 2, preventing it from bending and deforming due to stress during concrete pouring, thereby ensuring the dimensional accuracy and appearance quality of the steps.

[0046] b. Flexible Design, Enhanced Adaptability: The design of the first strip hole 5 and the second strip hole 8 on the reinforcing rod 4, as well as the connecting hole 9 on the top of the side plate 1, significantly improves the flexibility of template installation and use. The first strip hole 5 facilitates the adjustment of the relative position of the reinforcing rod 4 and the support rod 3, adapting to dimensional deviations under different construction scenarios; the cooperation between the second strip hole 8 and the connecting hole 9 provides greater adjustment space for the connection between the side plate 1 and the reinforcing rod 4, enabling the template to be flexibly adjusted according to on-site construction conditions and the specific dimensional requirements of the reservoir steps.
