Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a positioning device for impermeable concrete formwork. Background Technology

[0002] In the construction of thermal power plants, many structures consist of pool-like structures. The conventional construction process for pouring sidewalls involves welding waterstops onto tie rods, with the protective layer thickness controlled by spacers. However, these pool-like structures are located in silty geological conditions, making them prone to leakage. Water enters the sidewalls along the tie rods and then penetrates the pool structure. Conventional tie rods, relying solely on a single waterstop, are insufficient for effective water prevention and exhibit poor seepage resistance. Furthermore, the conventional process relies on manually added spacers, which are prone to displacement, leading to inaccurate control of the protective layer thickness. In short, existing sidewall pouring methods suffer from poor waterstopping and inaccurate control of the protective layer thickness. Utility Model Content

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0035] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0036] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0037] In the construction of thermal power plants, many structures consist of pool-like structures. The conventional construction process for pouring sidewalls involves welding waterstops onto tie rods, with the protective layer thickness controlled by spacers. However, relying solely on a single waterstop can easily lead to leakage; manually adding spacers can result in displacement, leading to inaccurate control of the protective layer thickness. In short, existing sidewall pouring methods suffer from poor water-stopping performance and inaccurate control of the protective layer thickness.

[0038] In view of this, the present invention provides a positioning device for impermeable concrete formwork, including a tie rod assembly 100 and a locking assembly; the tie rod assembly 100 includes a connecting rod 110, a waterstop plate 120 and a waterstop platform 130, the two ends of the connecting rod 110 are respectively connected to the waterstop platform 130, the waterstop plate 120 is connected to the connecting rod 110 and is disposed between the two waterstop platforms 130; the two locking assemblies are detachably connected to the two waterstop platforms 130 respectively, and the locking assemblies are used to clamp the concrete formwork 10.

[0039] The anti-seepage concrete formwork positioning device provided by this utility model provides a first layer of waterproofing through the water-stop platforms 130 at both ends of the connecting rod 110, and a second layer of waterproofing through the water-stop sheet 120 between the two water-stop platforms 130, thus improving the waterproofing effect. Simultaneously, the position of the locking component is controlled by the detachable connection between the water-stop platform 130 and the locking component, thereby fixing the distance between the concrete formwork 10 and the water-stop platform 130, achieving precise control of the protective layer thickness. Specifically, the distance between the end of the water-stop platform 130 connected to the connecting rod 110 and the concrete formwork 10 is the protective layer thickness.

[0040] The following combination Figures 1-6The structure and shape of the anti-seepage concrete formwork positioning device provided in this embodiment are described in detail:

[0041] In some optional embodiments, the tie rod assembly 100 further includes a limiting rod 140, which is connected to the waterstop platform 130 and perpendicular to the connecting rod 110; the limiting rod 140 is disposed at one end of the waterstop platform 130 near the waterstop plate 120 and is used to abut against the reinforcing bar 20.

[0042] In an optional embodiment, the water-stop platform 130 is provided with a mounting groove 131, and the limiting rod 140 is inserted into the mounting groove 131, such as... Figure 3 As shown.

[0043] Furthermore, the waterstop plate 120, waterstop platform 130, and connecting rod 110 are welded together. In use, the welded waterstop plate 120, waterstop platform 130, and connecting rod 110 are first inserted into the frame formed by the steel bars 20, and then the limiting rod 140 is inserted into the installation groove 131, so that the limiting rods 140 on both sides clamp the frame formed by the steel bars 20.

[0044] In some optional embodiments, the waterstop plate 120, waterstop platform 130, connecting rod 110, and limiting rod 140 are welded together, and installation is completed by rotating the pull rod assembly 100 at a certain angle during use. Specifically, as shown... Figure 2 As shown, the frame composed of steel bars 20 forms a rectangular grid. During installation, the limiting rod 140 is made parallel to the diagonal of the rectangular grid. After it is inserted into place, the tie rod assembly 100 is rotated to make the limiting rod 140 horizontal or vertical, so that the limiting rods 140 on both sides clamp the frame composed of steel bars 20.

[0045] In some optional embodiments, the water-stopping platform 130 is configured as a frustum shape, with the smaller diameter end connected to the connecting rod 110. That is, the smaller diameter end points inward to the side wall, and the larger diameter end points outward to the side wall, which helps to prevent water from entering the side wall.

[0046] In some optional embodiments, the outer diameter of the waterstop 120 is in the range of 70 to 90 mm; the connecting rod 110 is made of round steel and the diameter is in the range of 12 to 14 mm.

[0047] In an optional embodiment, the locking assembly includes a connecting platform 210, a connecting screw 220, and a locking nut 230. The connecting platform 210 is detachably connected to the water-stop platform 130, and one end of the connecting screw 220 is connected to the connecting platform 210; the locking nut 230 is fitted onto the connecting screw 220 and threadedly connected to it. That is, the concrete formwork 10 is clamped and fixed by the connecting platform 210 and the locking nut 230.

[0048] Furthermore, one end of the connecting screw 220 is inserted into the connecting platform 210 and threadedly connected to the connecting platform 210. The connecting screw 220 can also be welded to the connecting platform 210.

[0049] In an optional embodiment, the locking assembly further includes a U-shaped clamp 240 and a locking rod 250. The locking rod 250 clamps the concrete formwork 10 with the connecting platform 210; the locking nut 230 abuts against the U-shaped clamp 240 to ensure the U-shaped clamp 240 abuts against the concrete formwork 10. Specifically, the locking rod 250 is vertically arranged and made of steel pipe. That is, by adding the locking rod 250 fixed by the U-shaped clamp 240, the concrete formwork 10 is better secured.

[0050] In some optional embodiments, the end of the water-stop platform 130 opposite to the connecting rod 110 has a slot 132 and a circular groove 133, and the slot 132 and the circular groove 133 are connected, such as... Figure 4 As shown. Specifically, slot 132 is a rectangular through slot, and circular slot 133 has a circular cross-section. The connecting platform 210 includes a body 211, a first rod 212, and a second rod 213 connected in sequence. The first rod 212 and the second rod 213 are perpendicular to each other, and the second rod 213 is perpendicular to the connecting rod 110, as shown. Figure 6 As shown; the second rod 213 passes through the slot 132 and is inserted into the circular slot 133, the width of the slot 132 being less than the length of the second rod 213.

[0051] In use, the second rod 213 is inserted into the circular slot 133 and rotated 90° to prevent the second rod 213 from coming out. The width of the slot 132 refers to the short side of the cross-section of the slot 132, and the length of the long side of the cross-section of the slot 132 is greater than the length of the second rod 213 to ensure that the second rod 213 can pass through.

[0052] In some optional embodiments, the body 211 is configured as a frustum shape, with the smaller diameter end connected to the first rod 212, facilitating the removal of the body 211 from the side wall. Further, the diameter of the smaller diameter end of the body 211 is equal to the diameter of the larger diameter end of the water-stop platform 130. Even further, the generatrices of the body 211 and the water-stop platform 130 are collinear.

[0053] In an optional embodiment, the larger diameter end of the main body 211 is flush with the wall surface, and the length of the tie rod assembly 100 is the side wall thickness minus the length of two main bodies 211. The total length of the waterstop platform 130 and the connecting platform 210 after assembly is the thickness of the concrete protective layer, used to precisely control the size of the protective layer.

[0054] The working process of the anti-seepage concrete formwork positioning device provided in this embodiment is as follows:

[0055] First, insert the second rod 213 of the connecting platform 210 into the circular groove 133 of the waterstop platform 130 and rotate it to lock it in place. Then, place the assembled part inside the formwork 10 to be poured concrete.

[0056] Then, insert the limiting rod 140 into the mounting groove 131 so that the limiting rod 140 abuts against the steel bar 20 on the side wall. At this time, the total length of the waterstop platform 130 and the connecting platform 210 after assembly is the thickness of the protective layer. Then, screw the two connecting bolts 220 into the two connecting platforms 210 respectively.

[0057] Next, the U-shaped clip 240 is fitted onto the connecting screw 220, and the locking rod 250 is engaged in the groove of the U-shaped clip 240. Then, the locking nut 230 is fitted onto the connecting screw 220 and screwed in, thereby pressing the U-shaped clip 240 against the concrete formwork 10, so that the U-shaped clip 240 presses the locking rod 250 against the concrete formwork 10. The degree of compression can be adjusted by rotating the locking nut 230, thereby ensuring the verticality of the concrete formwork 10, and consequently, the verticality of the sidewalls.

[0058] During disassembly, first remove the locking nut 230 and the U-shaped clip 240, then rotate the connecting screw 220 to separate it from the connecting platform 210. The locking nut 230, U-shaped clip 240, connecting screw 220, and locking rod 250 can be reused. Alternatively, the connecting platform 210 can be rotated using the connecting screw 220 and pulled out of the cast side wall for reuse; if the connecting platform 210 cannot be removed, only the connecting screw 220 needs to be removed.

[0059] In this embodiment, concrete protective layers of different sizes can be obtained by selecting connecting platforms 210 of different lengths.

[0060] The anti-seepage concrete formwork positioning device provided in this embodiment achieves a good water-stopping effect through double-layer water-stopping, and accurately controls the thickness of the concrete protective layer by replacing the pad block with the water-stopping platform 130 and the connecting platform 210. It also has the advantages of convenient disassembly and reusability of some parts, which reduces construction costs and improves construction efficiency.

[0061] 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 it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
