Description

Technical Field

[0001] This application relates to the field of water supply and drainage pipeline construction, and in particular to a positioning mold for the construction of reserved ports of water supply pipes. Background Technology

[0002] With the development of architectural design, modern buildings are becoming increasingly multifunctional, multi-configured, and large-scale. As fully furnished apartments become more common, traditional water supply pipe ports can no longer meet the needs of customers. Many unfinished apartments require modifications to their water supply and drainage pipes during the renovation process.

[0003] During the renovation process, trenches are dug in the wall for the placement of pipes. After the pipes are installed and positioned, the trenches are filled with concrete. The reserved port of the water supply pipe can be regarded as the end of a cantilever structure during this process. It is very easy for it to sway and shift before and after pouring, which ultimately results in low accuracy of the pipe end position after construction and fails to meet the requirements of fine construction. Summary of the Invention

[0004] To address the aforementioned issues, this application provides a construction positioning mold for reserved ports on water supply pipes.

[0005] The technical solution for the construction positioning mold for reserved ports of water supply pipes provided in this application is as follows:

[0006] A construction positioning mold for a reserved port of a water supply pipe includes a pad, a template, and an adjustment mechanism. The pad is fixed to the wall, and the template is provided with a matching pipe clamp. The template is located on the side of the pad away from the wall. The end of the water supply pipe passes through the pad and is fixed relative to the matching pipe clamp on the template. The adjustment mechanism is used to adjust the position of the template relative to the pad.

[0007] By adopting the above technical solution, the pad is fixed to the wall, the template is fixed to the end of the water supply pipe by means of pipe clamps, the adjustment mechanism adjusts the position of the template, and at the same time adjusts and fixes the position of the end of the water supply pipe. Then, when the concrete is poured, the position of the end of the water supply pipe on the wall can be highly accurate.

[0008] Preferably, the adjusting mechanism includes a fastening bolt, the axis of which is perpendicular to the surface of the template, the fastening bolt passes through the template and is threadedly connected to the pad, and the nut of the fastening bolt abuts against the side of the template away from the pad; the number of the mating pipe clamps and the number of water supply pipe ends are both greater than two and correspond one-to-one, and there are multiple fastening bolts, with each fastening bolt located between two adjacent mating pipe clamps.

[0009] By adopting the above technical solution, the nuts of the fastening bolts limit the displacement of the template on the side of the template away from the pad, and the template can no longer move away from the pad.

[0010] Preferably, the adjustment mechanism includes a thrust member and a control component. The thrust member moves relative to the pad, and the control component controls the movement of the thrust member. When the thrust member moves, it generates a thrust on the template, causing the template to move away from the pad.

[0011] By adopting the above technical solution, the thrusting component applies a thrust to the template between the pad and the template, and together with the nuts of the fastening bolts, the template is placed in a specific position.

[0012] Preferably, the plurality of the mating pipe clamps are oriented in a specific direction, the thrusting component is a push rod, and the adjusting mechanism further includes a fixed rod and a force-bearing rod. The fixed rod is fixedly connected to the pad, and the force-bearing rod is located on the side of the template facing the pad and abuts against the surface of the template. The length directions of the push rod, fixed rod, and force-bearing rod are all parallel to the arrangement direction of the plurality of mating pipe clamps. The side walls of the push rod, fixed rod, and force-bearing rod are all provided with arc surfaces. The moving direction of the push rod is parallel to the surface of the pad and perpendicular to the length direction of the fixed rod. The force-bearing rod is located between the fixed rod and the push rod, and the side wall of the force-bearing rod is abutted by both the push rod and the force-bearing rod.

[0013] By adopting the above technical solution, when the push rod approaches the fixed rod, the arc surfaces of the two rods can clamp and push the force-bearing rod between them, causing the force-bearing rod to move. The force-bearing rod's force-bearing points are distributed throughout its entire length direction, and the thrust is eventually evenly transmitted to the template. This results in a smaller deflection deformation of the template due to uneven distribution of force-bearing points along its own length direction, thus improving the template's adjustment accuracy.

[0014] Preferably, the template is provided with a connecting spring, one end of which is connected to the template, and the other end is fixedly connected to a connecting ring. The connecting ring is sleeved on the force-bearing rod, and the extension and retraction direction of the connecting spring is parallel to the surface of the template and perpendicular to the length direction of the force-bearing rod.

[0015] By adopting the above technical solution, as the push rod moves closer to the fixed rod, the spatial center position between the two also shifts continuously. The connecting spring and connecting ring enable the force-bearing rod to have a certain position adjustment amount relative to the template, automatically adapting to the spatial conditions between the push rod and the fixed rod.

[0016] Preferably, the pad includes multiple raising frames, which are stacked and arranged along the thickness direction of the pad, and the maximum stroke of the adjustment mechanism controlling the template movement is equal to the thickness of the raising frame with the smallest thickness.

[0017] By adopting the above technical solution, changing the number of shim frames allows for stepped adjustment of the template position, while moving the push rod after determining the number of shim frames allows for stepless adjustment. The two work together to make the relative distance between the template and the wall highly adjustable and adaptable.

[0018] Preferably, the control assembly includes a force-bearing wedge, a control rod, a control wedge, and an operating screw. A control seat is fixedly connected to the pad, the operating screw is threadedly connected to the control seat, the force-bearing wedge is fixedly connected to the push rod, the control rod is located on the side of the push rod away from the fixed rod and is slidably connected to the pad, the control wedge is fixedly connected to the side wall of the control rod, the wedge surface of the control wedge abuts against the wedge surface of the force-bearing wedge, the length direction of the control rod is consistent with the sliding direction and the same as the length direction of the push rod, the end of the operating screw abuts against one end of the control rod, the end of the operating screw pushes the control rod to move, and the control wedge pushes the force-bearing wedge and the push rod away from the control rod.

[0019] By adopting the above technical solution, the control rod moves under the thrust of the operating screw, the control wedge moves together with the control rod, and the force-bearing wedge and the push rod move closer to the fixed rod through the wedge surface transmission.

[0020] Preferably, the pad is connected to a plurality of tension springs, the extension and retraction direction of the tension springs is perpendicular to the surface of the pad, and the end of the tension spring away from the pad is connected to the template.

[0021] By adopting the above technical solution, the tension spring is tightened so that the template has a tendency to move closer to the pad before the fastening bolts are tightened, so that the push rod can push the template to meet the plate, making it easier for the operator to make high-precision adjustments to the template.

[0022] Preferably, the pad is further provided with a backstop block, which is located at the end of the control rod away from the control seat. A backstop bolt is passed through the backstop block. A backstop threaded hole for the backstop bolt to be screwed into is opened at the end of the control rod near the backstop block. The axes of the backstop bolt and the backstop threaded hole are parallel to the length direction of the control rod. A control groove for the control rod to slide is opened on the pad. An expansion hole is opened on the control rod and on the wall of the backstop threaded hole. An expansion protrusion is fixedly connected to the wall of the expansion hole. One side of the expansion protrusion abuts against the backstop bolt, and the other side abuts against the groove wall of the control groove.

[0023] By adopting the above technical solution, after the template position is adjusted to the design position, the anti-reverse bolt is screwed into the anti-reverse threaded hole. The anti-reverse bolt applies tension to the control rod through the thread pair, keeping it in a stable position. At this time, the operating screw can be removed. The principle of the expansion protrusion is similar to that of the expansion nut. At the same time, it abuts against the groove wall of the anti-reverse bolt and the control groove, which can increase the friction between itself and the two adjacent objects, improve the positional stability of the anti-reverse bolt and the control rod, and thus improve the positional stability of the force-bearing rod and the template.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. By setting up a pad, template and adjustment mechanism, the pad is fixed to the wall, the template is fixed to the end of the water supply pipe by means of pipe clamps, and the adjustment mechanism adjusts the position of the template, and at the same time adjusts and fixes the position of the end of the water supply pipe. Then, when pouring concrete, the position of the end of the water supply pipe on the wall can have a high degree of accuracy.

[0026] 2. By using a push rod, a fixed rod, and a force-bearing rod with curved surfaces, when the push rod approaches the fixed rod, the curved surfaces of both can clamp and push the force-bearing rod between them, causing the force-bearing rod to move. The force-bearing rod's force-bearing points are distributed throughout its entire length, and the thrust is ultimately transmitted evenly to the template. This results in less deflection deformation of the template due to uneven force-bearing point distribution along its length, thus improving the template's adjustment accuracy.

[0035] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0036] This application discloses a construction positioning mold for reserved ports of water supply pipes, such as... Figure 1 and 2 As shown, it includes a base plate 2, a template 3, and an adjustment mechanism 4. The base plate 2 is used to directly fix it to the wall surface, and the template 3 is set on the side of the base plate 2 away from the wall surface. The template 3 is used to temporarily fix the end of the water supply pipe, and the adjustment mechanism 4 is used to change and control the relative distance between the template 3 and the base plate 2.

[0037] like Figure 1 and 2 As shown, the pad 2 and the wall are fixed with screws. The screws pass through the pad 2 and are screwed into the wall, and the surface of the pad 2 is in contact with the wall. The length direction of the water supply pipe end 1 is horizontal and perpendicular to both the wall and the surface of the pad 2. The pad 2 has a through hole for the water supply pipe end 1 to pass through. The template 3 is equipped with a matching pipe clamp 31, which is connected to the water supply pipe end 1 for relative fixation. When the template 3 moves, the water supply pipe end 1 can move with the template 3 through the matching pipe clamp 31. In this embodiment, there are four water supply pipes, and the ends of the four water supply pipes are arranged sequentially at a fixed distance along the horizontal direction. Therefore, the number of through holes on the pad 2 and the number of matching pipe clamps 31 on the template 3 are both four.

[0038] like Figure 1 , 2As shown in Figure 3, the pad 2 includes multiple raised frames 21, which are stacked along the thickness direction of the pad 2. Each raised frame 21 has a different thickness, such as 2cm, 1.5cm, 1cm, etc. Multiple raised frames 21 of various thicknesses need to be combined according to the site requirements. The adjustment mechanism 4 includes fastening bolts 41, a thrust member, and a control component 5. The thrust member moves relative to the pad 2, and the control component 5 is used to control the movement of the thrust member. When the thrust member moves, it generates a thrust on the template 3, causing it to move away from the pad 2. The axis of the fastening bolts 41 is perpendicular to the surface of the template 3. The raised frames 21 have through holes for the ends of the fastening bolts 41 to be inserted. The through hole on the raised frame 21 closest to the template 3 is a threaded hole. The fastening bolts 41 pass through the template 3 and are threadedly connected to the pad 2 closest to the template 3. The nut of the fastening bolt 41 abuts against the side of the template 3 away from the pad 2. That is, one side of the template 3 receives the thrust from the thrusting component, and the other side receives the abutting force from the nut of the fastening bolt 41. The combined effect of the two forces keeps the template 3 in a relatively fixed position. There are multiple fastening bolts 41, and each fastening bolt 41 is located at the midpoint between two adjacent mating pipe clamps 31.

[0039] like Figure 3 and 4 As shown, the thrusting component is a push rod 42. The adjusting mechanism 4 also includes a fixed rod 44 and a force-bearing rod 43. The fixed rod 44 is fixedly connected to the pad 2. The force-bearing rod 43 is connected to the side of the template 3 facing the pad 2 and abuts against the surface of the template 3. A connecting spring 32 is provided on the side of the template 3 facing the pad 2. There are multiple connecting springs 32 and they are evenly arranged on both sides of the force-bearing rod 43. One end of the connecting spring 32 is connected to the template 3, and the other end is fixedly connected to a connecting ring 33. The connecting ring 33 is sleeved on the force-bearing rod 43. Several annular grooves for the connecting ring 33 to be coaxially embedded are opened on the rod wall of the force-bearing rod 43. The extension and retraction direction of the connecting spring 32 is parallel to the surface of the template 3 and perpendicular to the length direction of the force-bearing rod 43. In the natural state, the length directions of the force-bearing rod 43, the push rod 42 and the fixed rod 44 are all parallel to the arrangement direction of the multiple mating pipe clamps 31.

[0040] like Figure 3 , 4 As shown in Figure 5, there are two of each of the push rod 42, fixed rod 44, and force-bearing rod 43, which are symmetrically arranged on opposite sides of the mating pipe clamp 31. The moving direction of the push rod 42 is parallel to the surface of the pad 2 and perpendicular to the length direction of the fixed rod 44. The force-bearing rod 43 is a round rod. The side walls of both the push rod 42 and the fixed rod 44 are arc-shaped. The force-bearing rod 43 is located between the fixed rod 44 and the push rod 42. When the push rod 42 moves closer to the fixed rod 44, the space between them decreases. The side wall of the force-bearing rod 43 is simultaneously abutted by the arc-shaped side walls of the push rod 42 and the force-bearing rod 43 and receives the abutting thrust from both of them.

[0041] like Figure 1 , 4 As shown in Figure 5, six tension springs 22 are connected to the side of the pad 2 closest to the template 3. The six tension springs 22 are evenly distributed along the edge contour of the template 3. The extension and retraction direction of the tension springs 22 is perpendicular to the surface of the pad 2, and the end of the tension spring 22 away from the pad 2 is fixedly connected to the template 3. In its natural state, the tension springs 22 transmit tension to the template 3, causing the template 3 to continuously tend to move closer to the pad 2. When the distance between the push rod 42 and the fixed rod 44 is large enough that the side wall of the force-bearing rod 43 abuts against the surface of the pad 2, the template 3 is at the position closest to the pad 2 in its stroke. When the push rod 42 moves to abut against the fixed rod 44, the force-bearing rod 43 and the template 3 are at the position furthest from the pad 2 in their stroke. The maximum stroke of the template 3 is equal to the thickness of the smallest pad frame 21, which is 1 cm. This mechanism combines stepped adjustment and stepless adjustment, thus making the relative distance between the template 3 and the wall highly adjustable and adaptable.

[0042] like Figure 3 , 4 As shown in Figure 5, the control assembly 5 includes a force-bearing wedge 53, a control rod 51, a control wedge 52, and an operating screw 54. A control seat 24 is fixedly connected to the edge of the pad 2 near the template 3. The operating screw 54 is threadedly connected to the control seat 24. The control rod 51 is located on the side of the push rod 42 away from the fixed rod 44 and is slidably connected to the pad 2. The pad 2 has a control groove 23 for the control rod 51 to be inserted and slide along it. The length direction of the control rod 51 is consistent with the sliding direction and is the same as the length direction of the push rod 42. The length direction of the operating screw 54 is consistent with the length direction of the control rod 51. The end of the operating screw 54 abuts against one end of the control rod 51. That is, when the operating screw 54 rotates and moves close to the control rod 51, it can generate a thrust on the control rod 51 along its length direction.

[0043] like Figure 3As shown, the control wedge 52 is fixedly connected to the side wall of the control rod 51, and the force-bearing wedge 53 is fixedly connected to the push rod 42. The number of control wedges 52 on a single control rod 51 and the number of force-bearing wedges 53 on a single push rod 42 are consistent with the number of mating pipe clamps 31, and the wedge surface of the control wedge 52 abuts against the wedge surface of the force-bearing wedge 53. When the operating screw 54 moves and pushes the control rod 51 to move, the wedge surface engagement transmission between the control wedge 52 and the force-bearing wedge 53 causes the force-bearing wedge 53 to tend to move away from the control rod 51. The force-bearing wedge 53, under the thrust, can carry the push rod 42 closer to the fixed rod 44, thereby realizing the abutment and push of the force-bearing rod 43. The force-bearing points of the force-bearing rod 43 are distributed throughout its entire length direction, and the thrust is ultimately transmitted evenly to the template 3. This results in a smaller deflection deformation of the template 3 due to the uneven distribution of force-bearing points along its length direction, improving the adjustment accuracy of the template 3.

[0044] like Figure 6 and 7 As shown, the pad 2 is also provided with a backstop block 25, which is located at the end of the control rod 51 away from the control seat 24. A backstop bolt 55 passes through the backstop block 25. The end of the control rod 51 near the backstop block 25 has a backstop threaded hole 511 for the backstop bolt 55 to be screwed into. The axes of the backstop bolt 55 and the backstop threaded hole 511 are parallel to the length direction of the control rod 51. After the position of the template 3 is adjusted, all fastening bolts 41 need to be tightened. Then, the backstop bolt 55 is inserted into the backstop block 25 and screwed into the backstop threaded hole 511. The threaded pair of the two provides a pulling force to the control rod 51 based on the backstop block 25. This pulling force is used to replace the thrust from the operating screw 54 to keep the control rod 51 in a stable position. Then the operating screw 54 can be removed. The backstop block 25 has a countersunk groove for placing the nut of the backstop bolt 55. An expansion hole 512 is provided on the control rod 51 and on the wall of the anti-reverse threaded hole 511. An expansion protrusion 513 is fixedly connected to the wall of the expansion hole 512. After the anti-reverse bolt 55 is screwed into the anti-reverse threaded hole 511, one side of the expansion protrusion 513 abuts against the anti-reverse bolt 55 and the other side abuts against the groove wall of the control groove 23. Its principle is similar to that of an expansion nut, which can increase the friction between itself and two adjacent objects, improve the positional stability of the anti-reverse bolt 55 and the control rod 51, and thus improve the positional stability of the force-bearing rod 43 and the template 3.

[0045] The implementation principle of the construction positioning mold for the reserved port of the water supply pipe in this embodiment is as follows:

[0046] The number of support frames 21 is determined according to the design dimensions. The water supply pipe end 1 passes through the support plate 2 and locks with the matching pipe clamp 31 on the template 3. Then, the support plate 2 is fixed to the wall. During the fixing of the support plate 2, the arrangement direction of each matching pipe clamp 31 must be kept horizontal. If necessary, a level is used for measurement. After the support plate 2 is fixed, the distance between the template 3 and the support plate 2 is further adjusted by the adjustment mechanism 4 until the distance between the template 3 and the wall reaches the design dimension. After the distance dimension meets the requirements, the anti-reverse bolt 55 is screwed in, the various fastening bolts 41 are screwed in, and the operating screw 54 is removed. At this time, the positioning of the water supply pipe end is completed. Then, the pipe trench can be poured and filled. After the concrete in the pipe trench has solidified, the mold can be removed from the wall.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
