[0034] The following Figures 1 - 5 describes the specific structure and working principle of the adjustable template for the water retaining weir of the present utility model.

[0035] As Figures 1 to 3 shown, the adjustable template for the water retaining weir includes a connecting frame 10 and two telescopic frames 20. The two telescopic frames 20 are symmetrically arranged on both sides of the connecting frame 10. The connecting frame 10 and the two telescopic frames 20 cooperate to enclose a hollow area 30 with openings on both sides. Both ends of the two telescopic frames 20 are slidably inserted and connected to the connecting frame 10. The telescopic frame 20 is adapted to switch between an extended state and a retracted state to change the length of the hollow area 30.

[0036] The adjustable formwork for the water retaining weir provided by the present utility model has both ends of the two telescopic frames 20 slidably inserted and connected to the connecting frame 10, and the telescopic frames 20 are adapted to switch between the extended state and the retracted state; during use, by adjusting the length of the telescopic frames 20 inserted into the connecting frame 10, the length of the hollow area 30 is further changed, and then water retaining weirs of different lengths can be fabricated without on-site fabrication, effectively improving the construction efficiency; due to being reusable, the construction cost is effectively reduced.

[0037] In an embodiment of the present utility model, the connecting frame 10 and the two telescopic frames 20 cooperate to enclose a rectangular frame body, and the hollow area 30 is a rectangular hollow area 30, so the formed water retaining weir is a cuboid. The thickness of the rectangular frame body determines the thickness of the water retaining weir, so the thickness of the rectangular frame body is determined according to the height of the water retaining weir to be fabricated as required. Preferably, the cross-section of the hollow area 30 is trapezoidal, so that the width of the upper part of the formed water retaining weir is smaller than that of the lower part, which is convenient for the formwork to be taken out and more convenient to use.

[0038] In an embodiment of the present utility model, the material of the connecting frame 10 and the material of the telescopic frames 20 are both aluminum alloy materials. Using the formwork made of aluminum alloy materials not only reduces the weight of the formwork but also can prevent the formwork from rusting, prolonging the service life of the formwork.

[0039] In an embodiment of the present utility model, a plurality of protrusions are provided on the other side of the connecting frame 10, and the plurality of protrusions are arranged at intervals along the length direction of the connecting frame 10 (i.e., Figure 2 the left-right direction in ). During use, the protrusions are in contact with the concrete surface, forming a gap between the connecting frame 10 and the concrete surface, reducing the contact area between the connecting frame 10 and the concrete, and preventing the concrete from adhering to the connecting frame 10.

[0040] In an embodiment of the present utility model, as Figures 1 to 3 shown, the connecting frame 10 includes two connecting pipes 11, the two connecting pipes 11 are arranged in parallel, and the two connecting pipes 11 are arranged at intervals along the width direction of the connecting frame 10 (i.e., Figure 2 the up-down direction in ). The two ends of one telescopic frame 20 are correspondingly inserted into one ends of the two connecting pipes 11 respectively, and the two ends of the other telescopic frame 20 are correspondingly inserted into the other ends of the two connecting pipes 11 respectively; specifically, the left telescopic frame 20 is U-shaped, openings are provided at the left ends of the two connecting pipes 11, and the two ends of the left telescopic frame 20 are correspondingly inserted into the left ends of the two connecting pipes 11; the right telescopic frame 20 is U-shaped, openings are provided at the right ends of the two connecting pipes 11, and the two ends of the right telescopic frame 20 are correspondingly inserted into the right ends of the two connecting pipes 11.

[0041] In an embodiment of the present utility model, the lengths of the two connecting pipes 11 are equal, and the widths and thicknesses of the two connecting pipes 11 are equal. In this embodiment, the cross-section of the connecting pipe 11 is rectangular. Of course, the shape of the cross-section of the connecting pipe 11 is not limited to this, and it can also be trapezoidal.

[0042] In an embodiment of the present utility model, as Figures 1 to 3 shown, the connecting frame 10 further includes a reinforcing rod 12. The reinforcing rod 12 is located on one side of the connecting frame 10 and is connected to the two connecting pipes 11. Specifically, the two ends of the reinforcing rod 12 are riveted to the two connecting pipes 11 or integrally formed.

[0043] In an embodiment of the present utility model, the connecting frame 10 further includes two reinforcing rods 12. The two reinforcing rods 12 are arranged at intervals along the length direction of the connecting pipe 11. The two reinforcing rods 12 are parallel to each other. The two ends of one reinforcing rod 12 are connected to the right ends of the two connecting pipes 11, and the two ends of the other reinforcing rod 12 are connected to the left ends of the two connecting pipes 11.

[0044] In an embodiment of the present utility model, at least one end of the telescopic frame 20 is provided with a scale. By setting the scale, the operator can clearly understand the length of the telescopic frame 20 inserted into the connecting pipe 11. Since the lengths of the connecting pipe 11 and the telescopic frame 20 are known, after obtaining the length of the telescopic frame 20 inserted into the connecting pipe 11, the operator can directly obtain the total length of the adjustable formwork. The operator can quickly adjust the total length of the adjustable formwork according to the design requirements without using a ruler for length measurement, improving the construction efficiency.

[0045] In an embodiment of the present utility model, the water retaining weir adjustable formwork further includes at least two locking components 40. The at least two locking components 40 are connected to the corresponding telescopic frame 20 and the connecting pipe 11. The locking component 40 is used to adjust the length of the telescopic frame 20 inserted into the connecting frame 10. After the length of the telescopic frame 20 inserted into the connecting frame 10 is adjusted, the telescopic frame 20 is fixed by the locking component 40, so that the length of the adjustable formwork is fixed, effectively improving the quality of the water retaining weir.

[0046] In a specific embodiment of the present utility model, as Figure 2 shown, the water retaining weir adjustable formwork further includes four locking components 40. One locking component 40 is respectively arranged at one end of the two connecting pipes 11, and one locking component 40 is respectively arranged at the other end of the two connecting pipes 11. In this way, the two ends of the telescopic frame 20 can be fixed, effectively improving the stability of the adjustable formwork.

[0047] In a specific embodiment of the present utility model, as Figure 4 and Figure 5As shown, the locking assembly 40 includes an adjusting rod 41. A through hole is provided on one side of the connecting pipe 11 away from the hollow area 30. A guiding groove 13 and a plurality of positioning holes 14 are provided on one side of the telescopic frame 20 away from the hollow area 30. The guiding groove 13 extends along the length direction of the connecting pipe 11. Specifically, the guiding groove 13 is located in the middle of one side of the connecting pipe 11 away from the hollow area 30, and the width of the guiding groove 13 is greater than the outer diameter of the adjusting rod 41, ensuring that the adjusting rod 41 can slide freely within the guiding groove 13.

[0048] The plurality of positioning holes 14 are arranged at intervals along the length direction of the connecting pipe 11 and communicate with the guiding groove 13. After the adjusting rod 41 passes through the through hole, it is in sliding fit with the guiding groove 13. A positioning block 42 is provided at one end of the adjusting rod 41 close to the hollow area 30, and the positioning block 42 is in positioning fit with the positioning hole 14.

[0049] In a specific embodiment of the present utility model, as Figure 5 shown, the positioning hole 14 is a circular hole, the center of the positioning hole 14 is located on the center line of the guiding groove 13, and the positioning hole 14 communicates with the guiding groove 13. The positioning block 42 has a circular sheet-like structure. Of course, the shape of the positioning block 42 is not limited thereto and is specifically determined according to the shape of the positioning hole 14. After the positioning block 42 is snapped into the positioning hole 14, through the positioning fit between the positioning block 42 and the positioning hole 14, the adjusting rod 41 cannot move; when the positioning block 42 leaves a positioning hole 14, the adjusting rod 41 can slide along the guiding groove 13, and the positioning block 42 can move along with the adjusting rod 41 and move into other positioning holes 14.

[0050] In a specific embodiment of the present utility model, a pressing portion 43 is provided at one end of the adjusting rod 41 away from the hollow area 30, and the cross-sectional area of the pressing portion 43 is greater than the cross-sectional area of the adjusting rod 41. By providing the pressing portion 43, the contact area between the adjusting rod 41 and the operator's hand is increased, enabling the operator to easily push the adjusting rod 41 to move. Preferably, the side of the pressing portion 43 away from the adjusting rod 41 of the connecting pipe 11 is a hemispherical surface.

[0051] In a specific embodiment of the present utility model, as Figure 4 shown, the locking assembly 40 further includes an elastic member 44. The elastic member 44 is sleeved on the outer periphery of the adjusting rod 41. One end of the elastic member 44 abuts against the pressing portion 43, and the other end of the elastic member 44 abuts against the connecting pipe 11. Preferably, the elastic member 44 is a compression spring, and the compression spring is in a compressed state, ensuring that the positioning block 42 is snapped into the positioning hole 14 and ensuring that the length of the adjustable template does not change.

[0052] In a specific embodiment of the present utility model, there is a gap between the outer surface of the telescopic frame 20 and the inner wall of the connecting pipe 11, and the width of the gap is 2 mm - 6 mm. During the use of the adjustable formwork, sand in the concrete may enter the space between the telescopic frame 20 and the connecting pipe 11, causing the telescopic frame 20 to get stuck and unable to expand and contract. Therefore, a gap is reserved between the outer surface of the telescopic frame 20 and the inner wall of the connecting pipe 11. Even if sand enters, it will not cause the telescopic frame 20 to be blocked. Preferably, the connecting pipe 11 is provided with a plurality of through holes, and the plurality of through holes are arranged at intervals along the length direction of the connecting pipe 11. The sand entering the connecting pipe 11 can flow out through the through holes, ensuring that the telescopic frame 20 can slide freely.

[0053] In a specific embodiment of the present utility model, polymer coatings or silicate coatings are provided on both the outer surface of the telescopic frame 20 and the outer surface of the connecting frame 10. Since the telescopic frame 20 is in contact with concrete for a long time, concrete will adhere to its surface, and after the concrete solidifies, the telescopic frame 20 will be stuck in the connecting pipe 11 and unable to expand and contract. By providing polymer coatings or silicate coatings on the outer surface of the telescopic frame 20 and the outer surface of the connecting frame 10, the polymer coatings or silicate coatings can prevent concrete from adhering to the outer surfaces of the telescopic frame 20 and the connecting frame 10, effectively avoiding the occurrence of the situation where the telescopic frame 20 is blocked.

[0054] The usage method of the water retaining weir adjustable formwork. When in use, press the pressing part 43 by hand, so that the positioning block 42 extends out of the positioning hole 14, and the compression spring is further compressed; when pulling the telescopic frame 20 by hand, the adjusting rod 41 can slide along the guiding groove 13, and the positioning block 42 can move along with the adjusting rod 41. After adjusting the adjustable formwork to an appropriate length, release the pressing part 43. Under the action of the compression spring, the positioning block 42 is snapped into the positioning hole 14 to lock the telescopic frame 20, making the length of the adjustable formwork fixed. After the length of the adjustable formwork is fixed, it can be put into use.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present utility model.
