DETAILED DESCRIPTION OF THE EMBODIMENTS
[0025] To further understand the features, technical means, specific purposes and functions achieved by the present utility model, the present utility model will be further described in detail below in conjunction with the drawings and specific embodiments.
[0026] See Figures 1-3As shown in the figure, a formwork support and reinforcement device for basement anti-seepage construction includes a wall 1, formwork bodies 2 symmetrically arranged on both sides of the wall 1, a first vertical pipe 3 arranged on the wall 1 to support the formwork bodies 2, a support steel pipe 4 far from the formwork bodies 2 and close to one side of the first vertical pipe 3, a tension rod 5 arranged on the formwork bodies 2 to press the support steel pipe 4 and the first vertical pipe 3 against the formwork bodies 2, and a pressing mechanism 6 arranged on the tension rod 5 to press the gap between the formwork bodies 2 and the wall 1. The pressing mechanism 6 includes a wedge-shaped block 61, and an auxiliary limiting mechanism 7 arranged on the tension rod 5 to assist the wedge-shaped block 61 to rise or fall in the vertical direction.
[0027] When it is necessary to press the formwork bodies 2 against the wall 1, first place the first vertical pipe 3 on the ground and press the formwork bodies 2 against both sides of the wall 1. Then, horizontally arrange and install the fixed light pipes in an array on the first vertical pipe 3 in sequence, and fix the fixed pipes on the wall 1 and the formwork bodies 2 through the tension rod 5 in sequence. By adjusting the tension rod 5, the pair of formwork bodies 2 can be pressed against each other on the wall 1. Then, insert the wedge-shaped block 61 into the gap between the support steel pipe 4 and the formwork bodies 2, calculate the inclined plane angle and vertical dimension of the wedge-shaped block 61, so that the supporting force of the lower tension rod 5 is just transmitted to the horizontal joint of the formwork bodies 2 and the wall 1 through the wedge-shaped inclined plane, bear the lateral pressure of the concrete, tighten the tension rod 5, and control the insertion depth of the wedge-shaped block 61, ensuring the stiffness and density of the formwork bodies 2 at key parts, eliminating the adverse effects of the initial deformation of the support steel pipe on formwork support, and achieving the effects of preventing the wall 1 from cracking and leaking.
[0028] See Figure 3 As shown in the figure, the pressing mechanism 6 further includes pressing teeth 62 and a force-bearing block 63; the pressing teeth 62 are arranged on the wedge-shaped block 61 and contact the first support steel pipe 4, and a plurality of pressing teeth 62 are arranged along the inclined plane of the wedge-shaped block 61; the force-bearing block 63 is arranged on the wedge-shaped block 61, and the force-bearing block 63 is used to buffer the impact force received by the wedge-shaped block 61. The pressing teeth 62 are in a serrated reverse anti-slip shape, which can prevent the wooden wedge from being extruded and sliding as the lateral pressure increases during the concrete pouring process.
[0029] When the wedge block 61 is pressed against the gap between the support steel pipe 4 and the template main body 2, by tightening the tie rod 5 and controlling the depth of insertion of the wedge block 61 into the gap between the support steel pipe 4 and the template main body 2, the supporting force of the lower tie rod 5 can be exactly transmitted by a number of pressing teeth 62 provided on the wedge block 61 to the horizontal joint between the support steel pipe 4 and the template main body 2, bearing the lateral pressure of the concrete, effectively preventing the wooden wedge from being squeezed and sliding as the lateral pressure increases during the concrete pouring process, ensuring the compactness of the surfaces of the wall 1 and the two template main bodies 2 on both sides, eliminating adverse effects such as deformation and displacement of the template main body 2. The force-bearing block 63 is preferably made of rubber material, and the wedge block 61 can be inserted into the gap between the support steel pipe 4 and the template main body 2 by knocking the force-bearing block 63 with a tool.
[0030] See Figures 3-5 As shown, the auxiliary limiting mechanism 7 includes an auxiliary docking block 71, a docking plate 72 and a first positioning bolt 73; the auxiliary docking plate 72 is arranged on the tie rod; the docking plate 72 is arranged on the docking block; the first positioning bolt 73 is respectively threadedly connected to the auxiliary docking block 71 and the docking plate 72. An avoidance docking groove for the auxiliary docking block 71 to pass through is provided on the docking plate 72, and docking holes for the first positioning bolt 73 to be threadedly connected are provided on both the auxiliary docking block 71 and the docking plate 72.
[0031] When it is necessary to insert the wedge block 61 into the gap between the template main body 2 and the support steel pipe 4, first insert the docking plate 72 onto the auxiliary docking block 71 provided on the tie rod, and then install the first positioning bolt 73 on the auxiliary docking block 71 and the docking plate 72, achieving the effect of quickly installing the docking plate 72 onto the tie rod 5, reducing the assembly and installation time, and being convenient for disassembly and carrying.
[0032] See Figures 3-5 As shown, the auxiliary limiting mechanism 7 further includes a connecting block 74 and an auxiliary rolling wheel 75; the connecting block 74 is horizontally and linearly slidably arranged on the docking plate 72 and has a pair; the auxiliary rolling wheel 75 is rotatably arranged on the connecting block 74 and is used to contact the wedge block 61. The auxiliary rolling wheel 75 is preferably a rubber wheel, which can reduce the friction force in contact with the outside of the wedge block 61 and make the descending process of the wedge block 61 smoother.
[0033] When the docking plate 72 is quickly installed on the auxiliary docking block 71, the connecting block 74 can be quickly installed on the auxiliary docking block 71 synchronously. First, place the wedge-shaped block 61 between the connecting blocks 74 and make it contact with the auxiliary rolling wheel 75. Then, strike the force-receiving block 63 with a tool. At this time, the wedge-shaped block 61 is restricted by the auxiliary rolling wheel 75 and can stably descend in the vertical direction. During the descent, the auxiliary rolling wheel 75 can rotate following the descent movement of the wedge-shaped block 61, making the descent movement of the wedge-shaped block 61 more stable and preventing deviation. This can prevent the wedge-shaped block 61 from deviating when it is tightened due to the lack of restriction on the wedge-shaped block 61.
[0034] See Figure 5 and Figure 6 As shown, the auxiliary limiting mechanism 7 further includes a limiting groove 76, a sliding rod 77, and an adjusting screw 78. The limiting groove 76 is opened on the docking plate 72 and there are a pair of them. The sliding rod 77 is arranged on the connecting block 74 and is located in the limiting groove 76 for sliding in the horizontal linear direction. The adjusting screw 78 is threadedly installed on the sliding rod 77, and the adjusting screw 78 is used to abut against the limiting groove 76 to limit the movement of the sliding rod 77.
[0035] When it is necessary to adjust the spacing between the wedge-shaped block 61 and the template main body 2, first place the sliding rod 77 in the limiting groove 76. Since there are a pair of sliding rods 77, they can be restricted by the limiting groove 76 to slide in the horizontal linear direction. During the sliding, the sliding rod 77 can drive the connecting block 74 and the auxiliary rolling wheel 75 to move relatively away from or relatively close to the wedge-shaped block 61, achieving the clamping and limiting effect on the wedge-shaped block 61. After the adjustment, the adjusting bolt can be threadedly connected to the sliding rod 77 until the adjusting screw 78 abuts against the limiting groove 76, thereby fixing the adjusted auxiliary rolling wheel 75 and the sliding rod 77, preventing the connecting plate and the sliding rod 77 from freely sliding along the limiting groove 76 when the wedge-shaped block 61 descends, and controlling the gap between the connecting block 74 and the restricted wedge-shaped block 61 and the template main body 2 and the wall 1 by adjusting the abutting distance between the adjusting bolt and the sliding rod 77 and the limiting groove 76, improving the applicability.
[0036] See Figure 5 and Figure 6 As shown, the auxiliary limiting mechanism 7 further includes a limiting groove 79 and a positioning rod 791. The limiting groove 79 is opened on the connecting block 74 for the auxiliary rolling wheel 75 to rotate. The positioning rod 791 is arranged in the limiting groove 76 and there are several of them. The positioning rod 791 is used to restrict the rotational movement of the auxiliary rolling wheel 75.
[0037] When the auxiliary rolling wheel 75 rotates, it can stably rotate along the positioning rod 791 in the limiting groove 79.
[0038] The above embodiments merely represent one or several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the appended claims.
