Description

Technical Field

[0001] This utility model relates to the field of reservoir construction technology, and in particular to a modular fixing frame for reservoir dam construction. Background Technology

[0002] Reservoir construction consumes a significant amount of manpower and resources. Typical reservoir dams have a trapezoidal structure, storing water and releasing it when the water level rises. Current dam construction still utilizes scaffolding and other fixed structures to facilitate worker setup and monitoring of construction progress. Reservoirs with long spans and wide areas require extensive scaffolding, and assembling the dam structure is also time-consuming. Scaffolding primarily consists of steel pipes, clamps, and planks; the longer and taller the dam, the more materials are needed, and dismantling it later is cumbersome and poses safety risks. Utility Model Content

[0003] The purpose of this utility model is to provide a modular fixing frame for reservoir dam construction to solve the problems encountered in the background art.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A modular fixed frame for reservoir dam construction includes a template frame and an L-shaped support frame. Several template frames are laid out along the outer shape of the reservoir dam. The L-shaped support frame has an L-shaped structure and is fixed to the outer surface of the template frame by screws according to the number of layers. Several L-shaped support frames are provided in each layer. Perforations are opened on the plate of the L-shaped support frame, and steel wire ropes are inserted through the perforations to form a fence.

[0006] In the above scheme, the L support frame includes a vertical plate, a horizontal plate, and a support plate. The vertical plate is fixed vertically to the horizontal plate, the bottom of the horizontal plate is fixed obliquely to the support plate, and a reinforcing plate is fixed between the horizontal plate and the support plate. The ends of the horizontal plate and the support plate are respectively fixed to the outer surface of the template frame through connecting plates. The perforations are evenly arranged on the vertical plate.

[0007] Since the dam body is not entirely inclined and also has flat parts, during implementation, when the reservoir dam body is in a vertical state, the end of the horizontal plate is flush with the end of the support plate; when the reservoir dam body is in an inclined state, the end of the horizontal plate is located in front of the end of the support plate.

[0008] In the above scheme, two positioning holes are opened on the middle plate of the template frame, and the template frame is fixedly connected to the L support frame through the positioning holes and bolts.

[0009] In another embodiment, to support the cement in the dam body, the inner side of the formwork frame is also provided with reinforcing bars, which are vertically fixed to the inner side of the formwork frame. As a preferred embodiment, a tie frame is also installed on the outer side of the formwork frame, and the tie frame has welding holes, through which the reinforcing bars pass and are fixedly connected to the tie frame.

[0010] Compared with existing technologies, the advantages of this utility model are as follows: Several template frames are laid out along the outer shape of the reservoir dam, and they are all fastened together with bolts to form a modular structure. The L-shaped support frame, with its bottom as support, can hold scaffold boards, providing walking and working space for construction workers. Perforations are opened in the L-shaped support frame panels, through which steel wire ropes are inserted to form a fence, providing fence-like protection for construction workers, preventing falls, and improving construction safety. Furthermore, the steel wire ropes increase the strength of the fence, further enhancing construction safety. This fixed frame is installed on the outside of the reservoir dam using a modular method, making installation and disassembly very convenient, and greatly improving the work efficiency of reservoir construction.

These drawings are simplified schematic diagrams, illustrating only the basic structure of this utility model, and therefore only show the relevant components of this utility model.

[0020] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0021] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] Example 1, as Figure 1 , Figure 2 , Figure 4 , Figure 6 As shown, a modular fixing frame for reservoir dam construction includes a template frame 1 and an L-shaped support frame 2, which is mainly used to fix the external structure of the dam body during the integration process of reservoir dam construction.

[0023] Several formwork frames 1 are laid along the outer shape of the reservoir dam, and they are all fastened to each other with bolts to form an assembly-type structure. A layer of demolding formwork can also be laid on the outer shape of the reservoir dam as the final demolding component after the concrete has been formed and dried. After forming, the formwork frames 1 and the demolding formwork are removed, revealing the concrete reservoir dam body.

[0024] The L-shaped support frame 2 is fixed to the outer surface of the template frame 1 with screws according to the number of layers. There are several L-shaped support frames 2 in each layer. The bottom of the L-shaped support frame 2 is used as support to place scaffold boards, providing walking and working space for construction workers.

[0025] The L-support frame 2 has perforations 22 on its plate, through which steel wire ropes 27 are inserted to form a fence, providing fence-like protection for construction personnel to prevent falls and improve construction safety. In addition, the steel wire ropes 27 increase the strength of the fence and improve construction safety.

[0026] For details, please see Figure 2The L-shaped support frame 2 includes a vertical plate 21, a horizontal plate 23, and a support plate 24. The vertical plate 21 and the horizontal plate 23 are vertically welded and fixed. The bottom of the horizontal plate 23 is inclinedly welded and fixed to the support plate 24. A reinforcing plate 25 is also welded and fixed between the horizontal plate 23 and the support plate 24. The ends of the horizontal plate 23 and the support plate 24 are respectively fixed to the outer surface of the template frame 1 by connecting plates 26 and bolts. Perforations 22 are evenly distributed on the vertical plate 21. The vertical plate 21 is an I-beam, and its two side plates improve the protective effect. The steel wire rope 27 improves the construction safety.

[0027] Please see Figure 2 When the reservoir dam is in a vertical position, the end of the horizontal plate 23 is flush with the end of the supporting plate 24 in the vertical direction. Please refer to [link / reference]. Figure 3 When the reservoir dam body is tilted, the end of the horizontal plate 23 is located in front of the end of the support plate 24 in the vertical direction, so as to be fixed on the outside of the template frame 1.

[0028] To facilitate installation, two positioning holes 13 are provided on the middle plate of the template frame 1. The template frame 1 is fixedly connected to the L support frame 2 through the positioning holes 13 and bolts. The bolt fixing can improve work efficiency and save the construction period of the reservoir dam.

[0029] Example 2: To support the cement in the dam body, based on Example 1, please refer to... Figure 1 , Figure 4 , Figure 5 The inner side of the formwork frame 1 is also equipped with reinforcing bars 3, which are vertically fixed to the inner side of the formwork frame 1. When cement is poured into the dam body, the cement expands outward during storage. At this time, it can be pulled by the reinforcing bars 3. The reinforcing bars 3 do not need to be removed later, which can also improve the overall strength of the concrete dam body.

[0030] The other end of rebar 3 is fixed to the ground, and the end is anchored to it by welding a rebar segment, giving it higher support and tensile strength. Triangular welding can be used to increase the anchorage strength between rebar 3 and the ground, or a circular washer can be pre-embedded at the end to increase stability.

[0031] As a preferred embodiment, a tension frame 11 is also installed on the outer side of the formwork frame 1. The tension frame 11 is also welded from steel plates, and welding holes 12 are opened on the tension frame 11. The reinforcing bars 3 pass through the welding holes 12 and are fixedly connected to the tension frame 11. When the cement is being poured and set, the expansion force will squeeze the formwork frame 1 installed on the outer side. At this time, the reinforcing bars 3 are passed through the welding holes 12 and fixed to the tension frame 11, which plays a role in traction on the formwork frame 1.

[0032] After the reinforcing bar 3 passes through the welding hole 12 and extends out of the tension frame 11, a nut and washer can be fixed on the outside to lock the end of the reinforcing bar 3 onto the tension frame 11. The washer has a large area, which provides a larger coverage area for the tension of the reinforcing bar 3 and ensures the overall stability of the template frame 1.

[0033] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
