Description

Technical Field

[0001] The utility model belongs to the technical field of embedded pipes, and specifically relates to a positioning and connecting structure for wire embedded pipes. Background Art

[0002] Embedded pipes refer to pipes pre-buried in concrete, walls or other structures during the construction of buildings or civil structures. Usually, the type, specification and quantity of the pipes need to be determined according to actual requirements, and their accurate positions in the structure need to be determined. During installation, it is necessary to ensure that the pipes are firmly fixed to the structure to prevent displacement or damage during concrete pouring or other construction processes.

[0003] Among them, through retrieval, it is found that the application number is CN202222573465.9, a pre-buried positioner for preset holes in construction projects. This pre-buried positioner for preset holes in construction projects can drive multiple clamping plates outside the embedded pipe to shift synchronously by using the linkage mechanism, so as to realize the positioning of embedded pipes of different sizes, avoid the need for construction workers to carry multiple pre-buried positioners of different sizes, and thus greatly reduce the work intensity of construction workers and improve the construction effect to a certain extent. The deficiencies are as follows:

[0004] When the construction worker uses this pre-buried positioner for preset holes in construction projects to position the embedded pipe, loosen the fastening bolt so that the bent plate can be adjusted normally. During the rotation of the bent plate, the bent plate drives the gear ring to rotate, and the rotation of the gear ring will drive multiple gears to rotate synchronously, and then drive the rack to shift. The clamping plates thereon will also shift inwards or outwards synchronously, so that the clamping plates are in close contact with the embedded pipe. When positioning the embedded pipe through the clamping plates, since only the pipe orifice of the embedded pipe is positioned singly and there is no limit between the adjusting component and the annular frame, the pipe body of the embedded pipe is suspended, and when pouring concrete, the impact force generated by the concrete on the pipe body of the embedded pipe is likely to cause the embedded pipe to squeeze the adjusting component to loosen, resulting in displacement of the embedded pipe, and thus the positioning effect of this pre-buried positioner for preset holes in construction projects is relatively poor. Content of the Utility Model

[0005] The purpose of the utility model is to provide a positioning and connecting structure for wire embedded pipes in order to solve the problem that the positioning effect of the above-mentioned pre-buried positioner for preset holes in construction projects is relatively poor.

A pressing plate is fixedly installed on the end side of the damping telescopic rod A, and the pressing plate is arranged in an arc shape.

[0008] Among them, the positioning distance adjusting mechanism is composed of a limiting card slot A and a limiting card frame. The limiting card slot A is relatively embedded on the upper and lower sides of the adjusting frame.

The limiting card frame is slidably arranged inside the limiting card slot A in a fitting manner.

[0009] Among them, the positioning direction adjusting mechanism is composed of a damping telescopic rod B, a limiting block and a limiting card slot B. A damping telescopic rod B is fixedly installed between the inner side of the rotating frame and the side of the positioning frame C, and a spring is arranged in a matching manner on the outer side of the damping telescopic rod B. The side of the positioning frame C is arranged in an arc shape.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0021] In the present invention:

[0022] Embodiment 1: Refer to Figures 1-4 , a positioning and connecting structure for a wire embedded pipe, including an embedded pipe 1, a positioning frame A 2, a limit slide bar 204, a slide groove 205, a positioning frame B 3, an adjusting frame 301, a rotating frame 4 and a positioning frame C 401. Positioning frames A 2 are arranged oppositely on both sides of the embedded pipe 1. A limit slide bar 204 is fixedly installed on the side of one positioning frame A 2, and a slide groove 205 is fixedly installed on the side of the other positioning frame A 2. And the limit slide bar 204 is fitted and slidably arranged inside the slide groove 205. Positioning frames B 3 are fixedly installed on the other side of the positioning frame A 2. An adjusting frame 301 is slidably arranged on the inner side of the positioning frame B 3. A rotating frame 4 is rotatably arranged on the inner side of the adjusting frame 301 through a bearing. A positioning frame C 401 is slidably arranged on the inner side of the rotating frame 4. A clamping and installing mechanism for positioning different embedded pipes is arranged between the outer sides of the positioning frame A 2. A positioning distance adjusting mechanism for freely adjusting the positioning distance of the embedded pipe is arranged on the outer side of the positioning frame B 3. A positioning direction adjusting mechanism for freely adjusting the positioning direction is arranged on the side of the positioning frame C 401.

[0023] Refer to Figures 1-3 , further, the clamping and installing mechanism is composed of an adjusting thread groove 201, an adjusting screw 202, an adjusting disc 203, a groove 206, a rubber pressing pad 207, a damping telescopic rod A 208 and a pressing plate 209;

[0024] On the side of the positioning frame A2, an adjusting thread groove 201 is relatively embedded. Inside the adjusting thread groove 201, an adjusting screw rod 202 is rotationally arranged by means of thread engagement on the inner side. Between the side ends of the adjusting screw rod 202, an adjusting disc 203 is fixedly installed. On the side opposite surface of the positioning frame A2, a groove 206 is relatively embedded near the rear of the adjusting thread groove 201. Inside the groove 206, a rubber pressing pad 207 is fixedly installed on the inner side, and the rubber pressing pad 207 is arranged in an arc shape. On the front and rear sides of the inner wall of the groove 206, a damping telescopic rod A208 is fixedly installed, and a spring is arranged in a matching manner on the outer side of the damping telescopic rod A208. On the side end of the damping telescopic rod A208, a pressing plate 209 is fixedly installed, and the pressing plate 209 is arranged in an arc shape. When the staff needs to position the embedded pipe 1 for threading in the foundation to be poured, the positioning frame A2 is carried to the position where the embedded pipe 1 needs to be positioned, and the adjusting disc 203 is rotated to drive the adjusting screw rod 202 to rotate by means of thread engagement on the inner side of the adjusting thread groove 201, driving the limiting slide rod 204 to slide out of the sliding groove 205 to release the two positioning frames A2. The rubber pressing pads 207 on the opposite surfaces of the two positioning frames A2 are respectively brought into contact with both sides of the surface of the embedded pipe 1. While the limiting slide rod 204 slides into the sliding groove 205, the adjusting screw rods 202 on both sides of the adjusting disc 203 are screwed into the corresponding adjusting thread grooves 201, squeezing the pressing plate 209 to drive the damping telescopic rod A208 and the outer spring to contract. The contracted damping telescopic rod A208 and the outer spring generate a reaction force on the pressing plate 209, squeezing the rubber pressing pad 207 to closely adhere to the surface of the embedded pipe 1, and then the installation of the positioning frame A2 is completed, which is convenient for the staff to subsequently position the positioning frame A2 to the specified steel reinforcement cage position, improving the effect of positioning various specifications of embedded pipes 1.

[0025] Refer to Figures 1-4 , Further, the positioning distance adjusting mechanism is composed of a limiting card slot A302 and a limiting card frame 303;

[0026] A limiting groove A302 is relatively embedded in the upper and lower sides of the adjusting frame 301. There are several limiting grooves A302, and every two of them are arranged in an arc shape and are equally spaced side by side. On the upper and lower sides of the side of the positioning frame B3, limiting brackets 303 are rotatably arranged through rotating shafts and torsion springs. The limiting brackets 303 are arranged in an arc shape, and the limiting brackets 303 are fitted and slidably arranged inside the limiting groove A302. After the staff installs the positioning frame A2 at the designated position of the embedded pipe 1, the two adjusting frames 301 are pushed to slide in the inner side of the positioning frame B3 in opposite directions, squeezing the limiting brackets 303 to slide out of the limiting groove A302 and driving the torsion spring to be tightened through the rotation of the rotating shaft. After the concave surface of the arc shape of the positioning frame C401 on the side of the adjusting frame 301 is squeezed and contacts the surface of the steel bar, the tightened torsion spring rebounds and the limiting bracket 303 rotates through the rotating shaft, so that the limiting bracket 303 slides into the inner side of the relative limiting groove A302. After the adjusting frame 301 is limited and fixed, the positioning process of the embedded pipe 1 is completed. After positioning other positions of the embedded pipe 1 in the same way, when the staff fills the foundation pit with concrete, the impact force generated by the concrete on the embedded pipe 1 is not likely to cause the embedded pipe 1 to shift in position, which is convenient for the staff to freely position the embedded pipe 1 at different distances, and at the same time improves the effect of stably positioning and preventing the embedded pipe 1 from shifting.

[0027] Refer to Figures 2-4 , Further, the positioning direction adjusting mechanism is composed of a damping telescopic rod B402, a limiting block 403 and a limiting groove B404;

[0028] A damping telescopic rod B402 is fixedly installed between the inner side of the rotating frame 4 and the side of the positioning frame C401. A spring is arranged on the outside of the damping telescopic rod B402. The side of the positioning frame C401 is arc-shaped. Limiting blocks 403 are fixedly installed around the side of the positioning frame C401, and the limiting blocks 403 are cylindrical. A limiting card slot B404 is embedded on the side of the adjusting frame 301 close to the side of the positioning frame C401. There are several limiting card slots B404, and they are arranged at equal intervals in a circular manner. The limiting blocks 403 are slidably fitted inside the limiting card slot B404. When the staff needs to position the embedded pipe 1 at an inclined angle, they push the positioning frame C401 to drive the damping telescopic rod B402 and the outer spring to expand, so that the limiting blocks 403 slide out of the limiting card slot B404 and release the positioning frame C401. Then, they push the positioning frame C401 to drive the rotating frame 4 to rotate through the bearing. After the positioning frame C401 rotates to the appropriate positioning angle, they release the positioning frame C401 to make the damping telescopic rod B402 and the outer spring contract, and the limiting blocks 403 slide into the inner side of the relative limiting card slot B404. After fixing the positioning frame C401, the staff then extends the adjusting frame 301 in the same way. After the arc-shaped concave surface on the side of the positioning frame C401 presses against and contacts the steel bars, the positioning of one place of the embedded pipe 1 is completed. And the positioning of other positions of the embedded pipe 1 is processed in the same way, which is convenient for the staff to freely adjust the angle of the positioning frame C401 to position the embedded pipe 1 at different inclined angles. Embodiment

[0029] Such as Figure 4 、 Figure 5As shown in the figure, on the periphery of the side of the positioning frame C401 of the present utility model, limit blocks 403 are fixedly installed, and the limit blocks 403 are arranged in a cylindrical shape. A limit card slot B404 is embedded on the side of the adjusting frame 301 close to the side of the positioning frame C401. There are several limit card slots B404, and they are arranged in an equidistant and circumferential manner. In addition to the embodiment in which the limit block 403 is fitted and slidably arranged inside the limit card slot B404, there is another implementation manner. On the periphery of the side of the positioning frame C401, limit blocks 403 are fixedly installed, and the periphery of the limit blocks 403 is arranged in a relatively inclined shape. A limit card slot B404 is embedded on the side of the adjusting frame 301 close to the side of the positioning frame C401. There are several limit card slots B404, and they are arranged in an equidistant and circumferential manner. The inner periphery of the wall of the limit card slot B404 is arranged in a relatively inclined shape, and the limit block 403 is fitted and slidably arranged inside the limit card slot B404. When the staff pushes the positioning frame C401 to drive the rotating frame 4 to rotate through the bearing, the damping telescopic rod B402 and the outer spring are squeezed and expanded, so that the limit block 403 slides out of the limit card slot B404 to release the positioning frame C401. After the positioning frame C401 rotates to a suitable positioning angle, the positioning frame C401 is released, and the damping telescopic rod B402 and the outer spring contract, and the limit block 403 slides into the inner side of the relative limit card slot B404 to fix the positioning frame C401. Compared with the first implementation manner, the adjustment is more convenient.

[0030] Working principle: First, when the staff needs to position the embedded pipe 1 for threading in the foundation to be poured, carry the positioning frame A2 to the position where the embedded pipe 1 needs to be positioned, and turn the adjustment disc 203 to drive the adjustment screw 202 to engage and rotate inside the adjustment thread groove 201, driving the limit slide bar 204 to slide out of the chute 205 to release the two positioning frames A2. Then, press the rubber pads 207 on the opposite surfaces of the two positioning frames A2 against both sides of the surface of the embedded pipe 1 respectively. While the limit slide bar 204 slides into the chute 205, screw the adjustment screws 202 on both sides of the adjustment disc 203 into the corresponding adjustment thread grooves 201, squeezing the pressure plate 209 to drive the damping expansion rod A208 and the outer spring to contract, so that the contracted damping expansion rod A208 and the outer spring generate a reaction force on the pressure plate 209, squeezing the rubber pad 207 to closely adhere to the surface of the embedded pipe 1, and then complete the installation of the positioning frame A2. Then, when the staff needs to position the inclination angle of the embedded pipe 1, push the positioning frame C401 to drive the damping expansion rod B402 and the outer spring to expand, so that the limit block 403 slides out of the limit card slot B404 to release the positioning frame C401. Then, push the positioning frame C401 to drive the rotating frame 4 to rotate through the bearing. After the positioning frame C401 rotates to the appropriate positioning angle, release the positioning frame C401 to make the damping expansion rod B402 and the outer spring contract, and the limit block 403 slides into the inner side of the opposite limit card slot B404 to fix the positioning frame C401. Finally, the staff pushes the two adjusting frames 301 to slide in the inner side direction of the positioning frame B3 towards the opposite direction, squeezing the limit card frame 303 to slide out of the limit card slot A302 and drive the torsion spring to be tightened through rotation of the rotating shaft. After the arc-shaped concave surface of the positioning frame C401 on the side of the adjusting frame 301 squeezes and contacts the surface of the steel bar, the tightened torsion spring rebounds, and the limit card frame 303 rotates through the rotating shaft, so that the limit card frame 303 slides into the inner side of the opposite limit card slot A302 to limit and fix the adjusting frame 301. After completing the positioning process of the embedded pipe 1 and positioning other positions of the embedded pipe 1 in the same way, when the staff fills the foundation pit with concrete, the impact force generated by the concrete on the embedded pipe 1 is not likely to cause the embedded pipe 1 to shift in position.

[0031] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
