DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific drawings.

[0025] As Figure 1 And Figure 2 As shown in a kind of concrete keyway formwork that can be quickly installed and disassembled, including the keyway mould 1 of top end opening and box-like, keyway mould 1 is connected with horizontal fixed plate 2 by several height telescopic rods in it, horizontal fixed plate 2 is connected with buckle device on both sides by several telescopic parts, buckle device includes the tight hoop cylinder 3 for steel bar card, the end of tight hoop cylinder 3 away from telescopic part is penetrated and is provided with deformation groove 4, and tight hoop cylinder 3 is provided with tight hoop bolt 5 on the side of deformation groove 4 position, the other side is provided with the connecting block 6 for the end of tight hoop bolt 5 to pass out, and the end of tight hoop bolt 5 is screwed with tight hoop nut 7 after passing out connecting block 6.

[0026] In addition, the middle end of the connecting block 6 is also provided with a through slot 8 for the end of the binding bolt 5 to pass out, and the side of the connecting block 6 away from the binding bolt 5 is provided with a connecting slot 9 for the fastening nut to be clamped into.

[0027] Before pouring the concrete wall, the arrangement interval and position of the key groove are determined, and at the same time, a plurality of steel bars are preferably arranged at the key groove setting position as the installation basis of the key groove mold 1. Then the steel bars are passed through the binding cylinder 3, and the key groove is aligned by the horizontal expansion and contraction of the expansion member and the longitudinal expansion of the height expansion rod. Then the fastening nut is rotated to gradually clamp the fastening nut into the connecting slot 9, so that the connecting block 6 drives the binding cylinder 3 to shrink and deform under the extrusion of the fastening nut, thereby clamping the steel bars, and the positioning and installation work of the key groove mold 1 is completed. For key grooves at different positions, the binding cylinder 3 only needs to be disassembled and the key groove mold 1 of the application is installed again using the steel bars, thereby improving the efficiency of engineering construction.

[0028] The application utilizes the steel bar positioning key groove mold 1, and adjusts the horizontal and height positions of the key groove mold 1 through the expansion member and the height expansion rod, so that the key groove mold 1 of the application can adapt to different engineering requirements without the need for re-production and positioning installation, thereby effectively reducing the workload caused by adding key grooves at the construction joints and improving the efficiency of engineering construction.

[0029] In addition, the application only needs to adjust and position the key groove mold 1 using a few preferred steel bars, i.e. within the adjustable range of the expansion member and the height expansion rod, to complete the pouring of the concrete in the key groove mold 1, without the need for removing a large number of steel bars, so that the demolding workload after the key groove pouring is completed is small.

[0030] As shown in Figure 4 The height expansion rod includes a bottom pipe 10 welded to the inner wall of the key groove mold 1 and an extension pipe 11 sliding in the bottom pipe 10, and the outer wall of the bottom pipe 10 is screwed with a binding screw 12 for limiting the sliding of the extension pipe 11, and one end of the binding screw 12 extends into the inside of the bottom pipe 10.

[0031] When adjusting the height of the key groove mold 1, only the extension pipe 11 needs to be expanded, so that the extension pipe 11 and the bottom pipe 10 slide relative to each other. After confirming the position of the key groove mold 1, the extension pipe 11 is fixed by the binding screw 12, so that the adjustment of the key groove mold 1 in the up-down height range can be realized.

[0032] As shown in Figure 4As shown, the horizontal fixed plate 2 is provided with a middle groove 13 along the length direction, and the length of the middle groove 13 is greater than the distance between the two height telescopic rods. The top end of the extension pipe 11 slides in the middle groove 13, and the extension pipe 11 is further provided with a limiting structure for limiting the sliding of the horizontal fixed plate 2. Specifically, the limiting structure includes a fixed bolt 14 fixed to the top end of the extension pipe 11, one end of the fixed bolt 14 extends out of the top of the middle groove 13 and is screwed with a fixed nut 15, the bottom of the fixed nut 15 is provided with a friction plate 16, the friction plate 16 is sleeved on the fixed bolt 14, and in addition, it should be noted that in this embodiment, the width of the middle groove 13 is greater than the diameter of the fixed bolt 14.

[0033] The length of the middle groove 13 is greater than the distance between the two height telescopic rods, so that the key groove mold 1 can be finely adjusted in the horizontal direction independently of the horizontal fixed plate 2, and the width of the middle groove 13 is greater than the diameter of the fixed bolt 14, so that the key groove mold 1 has a certain angle of micro-rotation, which is convenient for realizing the small-angle rotation adjustment of the key groove mold 1 in the horizontal range, so that the key groove mold 1 of the present application is more suitable for different needs of engineering.

[0034] In addition, when the horizontal fine adjustment and rotation fine adjustment of the key groove mold 1 are fixed, only the fixed nut 15 needs to be tightened, so that the fixed nut 15 rotates and presses the friction plate 16 downward, so that the friction plate 16 is pressed against the surface of the horizontal fixed plate 2, so that the fixed bolt 14 is not easy to shake, and the fine adjustment and fixation of the key groove mold 1 are realized.

[0035] As shown in the figure, Figure 3 The telescopic part includes a first horizontal telescopic rod 17 rotatably connected to the horizontal fixed plate 2, and a second horizontal telescopic rod 18 slidably connected to the first horizontal telescopic rod 17 and welded to the tight hoop cylinder 3.

[0036] Specifically, the first horizontal telescopic rod 17 is provided with a sliding groove one 19 along the length direction, and the horizontal fixed plate 2 is fixed with a plurality of first limiting screws 20 for clamping into the sliding groove one 19, and the top of the first limiting screw 20 is screwed with a first limiting nut 21. The rotation angle is confirmed by rotating the first horizontal telescopic rod 17 relative to the first limiting screw 20, and the position of the horizontal fixed plate 2 relative to the steel bar is confirmed by sliding the first limiting screw 20 in the sliding groove one 19, and finally the angle adjustment and length adjustment of the first horizontal telescopic part relative to the horizontal fixed plate 2 are realized by rotating the first limiting nut 21 to press the first horizontal telescopic rod 17.

[0037] The second limiting screw 22 is fixed in the sliding groove one 19, the second horizontal telescopic rod 18 is provided with a sliding groove two 23 along the length direction, one end of the second limiting screw 22 extends out of the sliding groove two 23 and is screwed with a second limiting nut 24, and the third limiting screw 25 is further fixed in the sliding groove one 19, one end of the third limiting screw 25 extends out of the sliding groove two 23 and is screwed with a third limiting nut 26.

[0038] The limiting of the second horizontal telescopic rod 18 by the second limiting screw 22 and the third limiting nut 26 makes the second horizontal telescopic rod 18 unable to rotate and only capable of sliding along the length direction of the first horizontal telescopic rod 17, thereby making the sliding of the second horizontal telescopic rod 18 more stable, and in addition, the fixed adjustment of the horizontal position of the second horizontal telescopic rod 18 is realized by the sliding of the second horizontal telescopic rod 18 and the compression and limiting of the second horizontal telescopic rod 18 by the second limiting nut 24 and the third limiting nut 26.

[0039] In addition, the fixing of the telescopic member and the height telescopic rod by the first limiting nut 21, the second limiting nut 24, the third limiting nut 26 and the tight screw 12 makes the key groove mold 1 also capable of being connected firmly through the installation and positioning of the four steel bars, and the deformation and displacement of the formwork in the pouring process is avoided.

[0040] The use process of the utility model includes the following steps:

[0041] a, before pouring the concrete wall, determine the key groove arrangement interval and position, and simultaneously select the four steel bars at the key groove setting position as the installation basis of the key groove mold 1;

[0042] b, adjust the opening and closing state of the tight hoop cylinder 3, pass the steel bars through the tight hoop cylinder 3 to preliminarily install the key groove mold 1 on the selected four steel bars;

[0043] c, according to the actual measurement of the key groove position, adjust the position of the horizontal fixing plate 2, the first horizontal telescopic rod 17 and the second horizontal telescopic rod 18 to preliminarily align the key groove positioning, and tighten the related nuts;

[0044] d, measure the key groove position deviation by using the measuring instrument, rotate the adjustable range of the middle groove 13 of the horizontal fixing plate 2 relative to the fixed bolt 14 to make fine adjustment, and after the adjustment is completed, use the fixed nut 15 to tighten the friction clamping piece to fix the top of the extension pipe 11;

[0045] e, control the telescopic length by using the tight screw 12 to adjust the key groove mold 1 to the corresponding height;
