Description

Technical Field

[0001] This utility model relates to the field of concrete pouring formwork construction technology, and more specifically, to a concrete pouring anti-leakage formwork fastening device. Background Technology

[0002] In the concrete pouring stage of building construction, a formwork frame needs to be built outside the steel cage first. Aluminum formwork panels are widely used due to their advantages such as light weight and high turnover rate. During the construction of the aluminum formwork panel frame, fastening devices are needed to secure the aluminum formwork panel frame. Existing fastening devices usually use clamps with U-shaped ends for end hooking and connection, and wedge irons are inserted and fixed to form a fastening structure outside the aluminum formwork panel frame.

[0003] Existing fastening devices use a frame formed by clamping plates and wedges to fasten the formwork. However, relying solely on the clamping force of the frame is insufficient to completely eliminate gaps in the formwork, resulting in limited fastening effectiveness. Furthermore, gaps in the aluminum formwork are prone to grout leakage, affecting the quality of concrete pouring and failing to meet the requirements of high-quality construction. Therefore, we propose a grout-proof formwork fastening device for concrete pouring. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a concrete pouring anti-leakage template fastening device to solve the technical problem that the current fastening device has a poor fastening effect on aluminum templates in aluminum formwork frames.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a concrete pouring anti-leakage template fastening device, including a rectangular aluminum template frame, T-shaped strips are arranged in the aluminum template gaps in the rectangular aluminum template frame, L-shaped sealing gaskets are arranged on both sides of the T-shaped strips, and several sets of rectangular fastening structures are arranged at equal intervals from top to bottom on the outside of the rectangular aluminum template frame, and top fastening bolts are movably arranged on the rectangular fastening structures;

[0006] The insertion end of the T-shaped strip is trapezoidal, with the larger end of the trapezoidal insertion end facing inwards from the rectangular aluminum template frame, and the smaller end facing outwards from the rectangular aluminum template frame. The shape of the aluminum template gap in the rectangular aluminum template frame matches the trapezoidal insertion end of the T-shaped strip.

[0007] Preferably, the rectangular fastening structure includes several sets of clamping plates, one end of each clamping plate being a U-shaped end, and the several sets of clamping plates being connected end-to-end through the U-shaped ends.

[0008] Preferably, the card plate has two sets of parallel insertion holes at the end facing away from the U-shaped end, and the two sets of parallel insertion holes are arranged in an alternating manner, with wedge-shaped iron inserted into the insertion holes.

[0009] Preferably, the card plate has a rectangular opening, and a slider is slidably arranged inside the rectangular opening, with the top fixing bolt passing through the slider.

[0010] Preferably, the inner wall of the rectangular opening is provided with symmetrical limiting strips on the top and bottom, and the slider is provided with symmetrical limiting grooves on the top and bottom, and the limiting grooves are inserted into the corresponding limiting strips.

[0011] Preferably, the top fixing bolt is rotatably arranged with a rectangular block facing one end of the rectangular aluminum template frame, and the T-shaped strip has a rectangular hole on its outer side that matches the rectangular block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model utilizes a designed T-shaped strip with L-shaped sealing gaskets on both sides and a top-fixing bolt on a rectangular fastening structure. Therefore, when fastening a rectangular aluminum formwork frame, the T-shaped strip can be directly inserted into the gap between the aluminum formwork panels within the frame. The rectangular fastening structure then secures the frame, and the top-fixing bolts on the structure press against the T-shaped strip, fixing it in place. Furthermore, the aluminum formwork panels within the frame press against the L-shaped sealing gaskets on both sides of the T-shaped strip, effectively ensuring a tight seal and preventing grout leakage from the gaps. This solves the technical problem of poor fastening performance of current fastening devices for aluminum formwork frames. Therefore, this utility model offers the advantage of better sealing performance for rectangular aluminum formwork frames.

[0014] 2. The T-shaped insert end of this utility model adopts a trapezoidal design, with the larger end of the trapezoidal insert end facing inwards from the rectangular aluminum formwork frame and the smaller end facing outwards. The shape of the aluminum formwork gap in the rectangular aluminum formwork frame matches the shape of the trapezoidal insert end of the T-shaped strip. Therefore, during concrete pouring, under the action of grouting expansion force, the trapezoidal insert end makes the T-shaped strip and the aluminum formwork gap in the rectangular aluminum formwork frame squeeze tighter and tighter, strengthening the sealing effect and further improving the sealing performance of the rectangular aluminum formwork frame.

[0024] like Figures 1 to 7 As shown, this utility model relates to a concrete pouring anti-leakage template fastening device, comprising: 1. a concrete pouring anti-leakage template fastening device, characterized in that it includes a rectangular aluminum template frame 1, T-shaped strips 3 are arranged in the aluminum template gaps in the rectangular aluminum template frame 1, L-shaped sealing gaskets 4 are arranged on both sides of the T-shaped strips 3, and a number of rectangular fastening structures 2 are arranged at equal intervals from top to bottom on the outside of the rectangular aluminum template frame 1, and top fastening bolts 6 are movably arranged on the rectangular fastening structures 2.

[0025] When fastening the rectangular aluminum formwork frame 1, the T-shaped strip 3 can be directly inserted into the gap between the aluminum formwork in the rectangular aluminum formwork frame 1. Then, a rectangular fastening structure 2 is installed on the outside of the rectangular aluminum formwork frame 1 to fasten the rectangular aluminum formwork frame 1. The top bolts 6 on the rectangular fastening structure 2 are then turned to press the T-shaped strip 3, thus fixing the T-shaped strip 3 in the gap between the aluminum formwork in the rectangular aluminum formwork frame 1. When the rectangular fastening structure 2 is fastening the rectangular aluminum formwork frame 1, the aluminum formwork in the rectangular aluminum formwork frame 1 will press the L-shaped sealing gaskets 4 on both sides of the T-shaped strip 3, thereby effectively ensuring the sealing of the rectangular aluminum formwork frame 1 and preventing grout leakage from the gap between the aluminum formwork in the rectangular aluminum formwork frame 1.

[0026] Specifically, the rectangular fastening structure 2 includes several sets of clamping plates 5, one end of which is a U-shaped end 501, and the several sets of clamping plates 5 are connected end to end by hooking the U-shaped end 501; the end of the clamping plate 5 facing away from the U-shaped end 501 is provided with two sets of parallel insertion holes 502, and the two sets of parallel insertion holes 502 are arranged in an alternating manner, and wedge-shaped irons 503 are inserted into the insertion holes 502; the clamping plates 5 are arranged around the rectangular aluminum template frame 1 by hooking the U-shaped end 501, and then wedge-shaped irons 503 are nailed into the corresponding insertion holes 502 on each set of clamping plates 5, thereby forming a fastening frame to fasten the rectangular aluminum template frame 1.

[0027] Furthermore, a rectangular opening 504 is provided on the card plate 5, and a slider 505 is slidably arranged inside the rectangular opening 504. The fixing bolt 6 is arranged through the slider 505. Symmetrical limiting strips 506 are arranged on the upper and lower sides of the inner wall of the rectangular opening 504. Symmetrical limiting grooves 507 are provided on the upper and lower sides of the slider 505, and the limiting grooves 507 are inserted into the corresponding limiting strips 506. With the cooperation of the limiting grooves 507 and the limiting strips 506, the slider 505 can slide freely in the rectangular opening 504. Then, the fixing bolt 6 can be moved and adjusted freely through the slider 505 to make it correspond to the T-shaped strip 3. Then, by tightening the fixing bolt 6, the fixing bolt 6 can be used to fix the T-shaped strip 3.

[0028] Furthermore, a rectangular block 601 is rotatably arranged on one end of the rectangular aluminum formwork frame 1, and a rectangular hole 301 matching the rectangular block 601 is opened on the outer side of the T-shaped strip 3. When the jacking bolt 6 jacks the T-shaped strip 3, the rectangular block 601 of the jacking bolt 6 is inserted into the rectangular hole 301 of the T-shaped strip 3, which can position the T-shaped strip 3 in the vertical direction and avoid vibration. The displacement of the T-shaped strip 3 in the vertical direction can better ensure the stability of the T-shaped strip 3 in the aluminum formwork gap in the rectangular aluminum formwork frame 1.

[0029] In the embodiments of this utility model, the insertion end of the T-shaped strip 3 is trapezoidal, and the larger end of the trapezoidal insertion end of the T-shaped strip 3 faces the inside of the rectangular aluminum template frame 1, while the smaller end of the trapezoidal insertion end of the T-shaped strip 3 faces the outside of the rectangular aluminum template frame 1. The shape of the aluminum template gap in the rectangular aluminum template frame 1 matches the trapezoidal insertion end of the T-shaped strip 3.

[0030] During concrete pouring, under the action of grouting expansion force, the trapezoidal insertion end makes the T-shaped strip 3 and the aluminum formwork gap in the rectangular aluminum formwork frame 1 squeeze tighter and tighter, strengthening the sealing effect and further improving the sealing performance of the rectangular aluminum formwork frame 1.

[0031] Working principle: This embodiment provides a concrete pouring anti-leakage formwork fastening device. First, when fastening the rectangular aluminum formwork frame 1, the T-shaped strip 3 can be directly inserted into the gap of the aluminum formwork in the rectangular aluminum formwork frame 1. Then, a rectangular fastening structure 2 is installed on the outside of the rectangular aluminum formwork frame 1 to fasten the rectangular aluminum formwork frame 1. The top bolt 6 on the rectangular fastening structure 2 is then turned to press the T-shaped strip 3, thereby fixing the T-shaped strip 3 in the gap of the aluminum formwork in the rectangular aluminum formwork frame 1. When the rectangular fastening structure 2 fastens the rectangular aluminum formwork frame 1, the aluminum formwork in the rectangular aluminum formwork frame 1 will press the L-shaped sealing gaskets 4 on both sides of the T-shaped strip 3, thereby effectively ensuring the sealing of the rectangular aluminum formwork frame 1 and preventing grout leakage from the gap of the aluminum formwork in the rectangular aluminum formwork frame 1.

[0032] Secondly, during concrete pouring, under the action of grouting expansion force, the trapezoidal insertion end makes the T-shaped strip 3 and the aluminum formwork gap in the rectangular aluminum formwork frame 1 squeeze tighter and tighter, strengthening the sealing effect and further improving the sealing performance of the rectangular aluminum formwork frame 1.
