Description

Technical Field

[0001] The invention relates to the field of building construction, and in particular to a positioning device for an auxiliary pipe penetrating a rigid waterproof casing and a use method thereof. Background Art

[0002] In order to prevent water from leaking out of the side walls of a general pool, all pipes passing through the pool must be covered with waterproof casings, which are divided into rigid and flexible types. Among them, rigid waterproof casings are generally used for pipes passing through the exterior walls of buildings; during the construction process, the rigid waterproof casing is poured into the wall to protect the pipes or facilitate the installation of the pipes, which is beneficial to the waterproofing of the wall.

[0003] After the pipe in the pipeline passes through the rigid waterproof casing, there is a gap between the pipe and the rigid waterproof casing, which needs to be twisted and sealed. In the current construction process, there is no control measure to make the pipe and the rigid waterproof casing coaxial. When twisting the pipe, the pipe may abut against the inner wall of the rigid waterproof casing, resulting in a gap between the two that allows water to seep after the twisting, which greatly reduces the waterproof performance of the twisted part. Therefore, a positioning device that assists the pipe to pass through the rigid waterproof casing is needed to solve the above problem. Summary of the invention

[0004] In order to improve the problems in the background technology, on the one hand, the present invention provides a positioning device for assisting pipes to pass through a rigid waterproof casing, comprising a stainless steel clamp, a steel sheet, and a plurality of wedge positioning blocks; the plurality of wedge positioning blocks are evenly distributed on the same side of the stainless steel clamp ring body along the circumferential interval of the stainless steel clamp, and the plurality of wedge positioning blocks are respectively connected to the stainless steel clamp through the steel sheet; the length direction of the steel sheet is parallel to the axis of the stainless steel clamp; the side of the wedge positioning block close to the axis of the stainless steel clamp is the first side, and the side away from the axis of the stainless steel clamp is the second side; the edge of one side of the first side away from the stainless steel clamp coincides with the edge of one side of the second side away from the stainless steel clamp, the overlapping edges of the two side surfaces are perpendicular to the axis of the stainless steel clamp, and the connection between the two side surfaces constitutes a flat sharp end of the wedge positioning block; the first side surface of each of the wedge positioning blocks is tangent to the outer side surface of the pipe that penetrates the stainless steel clamp, and the space through which the pipe can pass, which is surrounded by the first side surface of the wedge positioning block, is coaxial with the stainless steel clamp.

[0005] Preferably, at least four wedge positioning blocks are provided on the stainless steel clamp.

[0006] Preferably, a plurality of triangular prism-shaped grooves are evenly spaced on the second side surface of the wedge positioning block; the length direction of the groove is parallel to the overlapping edges of the first and second side surfaces, and passes through the two edges of the second side surface; the inner cavity surface of the groove is composed of a groove bottom surface and a groove side surface, the groove side surface is perpendicular to the axis of the stainless steel clamp, and the groove bottom surface is perpendicular to the groove side surface.

[0007] Preferably, a socket is provided on the side of the wedge positioning block close to the stainless steel clamp, and the wedge positioning block is sleeved on an end of the steel sheet away from the stainless steel clamp through the socket.

[0008] Preferably, the wedge positioning block is a wooden wedge.

[0009] A plurality of wedge positioning blocks are arranged on the stainless steel clamp, and the flat sharp end of the wedge positioning block can penetrate into the gap between the pipe and the rigid waterproof casing, and the first side surface of the wedge positioning block is tangent to the radial side surface of the pipe penetrated into the device, and can abut the pipe more tightly; the second side surface of the wedge positioning block forms an acute angle in the counterclockwise direction with the first side surface, and when the wedge positioning block penetrates into the gap between the pipe and the rigid waterproof casing to a certain extent, the second side surface of the wedge positioning block will abut against the port edge of the rigid waterproof casing, thereby limiting the displacement of the pipe in the rigid waterproof casing; since the wedge positioning blocks are evenly distributed on the stainless steel clamp, the pipe is subjected to the extrusion force of the wedge positioning blocks in different directions, so that the pipe is located in the middle of the rigid waterproof casing, realizing the coaxiality of the pipe and the rigid waterproof casing, and preventing the pipe from abutting against the inner wall of the rigid waterproof casing.

[0010] In addition, a number of triangular prism-shaped grooves are evenly spaced on the second side surface of the wedge positioning block, and the side surfaces of the grooves are perpendicular to the axis of the stainless steel clamp; when the wedge positioning block is inserted from its flat and sharp end into the gap between the pipe and the rigid waterproof casing until it is tightly abutted, the port edge of the rigid waterproof casing is inserted into the groove on the second side surface of the wedge positioning block and abuts against the side surfaces of the grooves; since the side surfaces of the grooves are perpendicular to the axis of the stainless steel clamp, that is, perpendicular to the length direction of the rigid waterproof casing, the side surfaces of the grooves of the multiple wedge positioning blocks arranged on the pipe can better abut against the port edges of the rigid waterproof casing, thereby preventing displacement of the pipe in the rigid waterproof casing.

[0011] On the other hand, the present invention provides a method for using a positioning device for assisting a pipe to penetrate a rigid waterproof casing, comprising the following steps:

[0012] 1) Select a suitable wedge positioning block according to the size of the pipe and the rigid waterproof casing, and set the wedge positioning block on the stainless steel clamp through the steel sheet;

[0013] 2) Pass one end of the pipe through the rigid waterproof casing to a suitable length, and sleeve one of the stainless steel clamps on the portion of the pipe located outside one end of the rigid waterproof casing, or sleeve two of the stainless steel clamps on the portions of the pipe located outside both ends of the rigid waterproof casing respectively; adjust the position of the stainless steel clamp so that the wedge positioning block passes through the rigid waterproof casing from its flat sharp end until the first side surface of each of the wedge positioning blocks is tightly against the outer side surface of the pipe and the second side surface thereof is tightly against the edge of the port of the rigid waterproof casing, and then tighten the clamp bolts to fix the stainless steel clamp;

[0014] 3) Install the pipe support and hanger to fix the pipe. After the pipe support and hanger are installed, loosen the clamp bolt, remove the stainless steel clamp from the pipe, and then remove the wedge positioning block from the stainless steel clamp;

[0015] 4) Waterproofing the gap between the pipe and the rigid waterproof casing.

[0016] Preferably, after the wedge positioning block penetrates into the gap between the pipe and the rigid waterproof sleeve, the stainless steel clamp is rotated until one of the wedge positioning blocks is located directly below the pipe.

[0017] According to the above operation, the stainless steel clamp is put on the pipe, and multiple wedge positioning blocks are tightly clamped into the gap between the pipe and the rigid waterproof casing to achieve the coaxiality of the pipe and the rigid waterproof casing. Then the pipe support and hanger are installed to fix the position of the pipe and the rigid waterproof casing. After removing the stainless steel clamp, the gap between the pipe and the rigid waterproof casing is twisted. The twisting material can cover the entire outer side of the pipe in the rigid waterproof casing, thereby improving the waterproof performance of the twisting point; a positioning device can be set on the outside of one end of the rigid waterproof casing, and positioning devices can also be set on the outside of both ends of the rigid waterproof casing respectively. The latter can effectively prevent the pipe from tilting or sagging in the rigid waterproof casing, causing it to abut against the inner wall of the rigid waterproof casing, and is therefore particularly suitable for pipes with higher density and heavier weight; rotating the stainless steel clamp so that one of the wedge positioning blocks is located directly below the pipe can better play the supporting role of the wedge positioning block.

[0018] In summary, this application has the following beneficial effects:

[0019] 1. The flat sharp end of the wedge positioning block of the positioning device can penetrate into the gap between the pipe and the rigid waterproof casing as the stainless steel clamp moves on the pipe. When the wedge positioning block penetrates into the gap between the pipe and the rigid waterproof casing to a certain extent, the first side surface of the wedge positioning block tightly abuts the pipe, and the second side surface tightly abuts the port edge of the rigid waterproof casing, thereby limiting the displacement of the pipe in the rigid waterproof casing; since the wedge positioning blocks are evenly distributed on the stainless steel clamp, the extrusion force on the pipe is evenly distributed, so that the pipe is clamped in the middle of the rigid waterproof casing by multiple wedge positioning blocks, achieving the coaxiality of the pipe and the rigid waterproof casing, and preventing the pipe from abutting against the inner wall of the rigid waterproof casing; in addition, by providing a triangular prism-shaped groove on the second side surface of the wedge limit block, the device can better play the role of preventing the pipe from abutting against the inner wall of the rigid waterproof casing.

[0020] 2. The positioning device is used to assist the pipe to penetrate the rigid waterproof casing, which can ensure that the twisting material covers the entire outer side of the pipe in the rigid waterproof casing, thereby improving the waterproof performance of the twisting joint. And for pipes with high density and heavy weight, positioning devices are respectively set on the outer sides of both ends of the rigid waterproof casing, which can effectively prevent the pipe from tilting or sagging in the rigid waterproof casing, causing it to abut against the inner wall of the rigid waterproof casing, and avoid the situation where the twisting material cannot cover the entire outer side of the pipe in the rigid waterproof casing; rotating the stainless steel clamp so that one of the wedge positioning blocks is located directly below the pipe can better play the supporting role of the wedge positioning block.

[0026] The following is combined with Figure 1-4The present invention is further described in detail. For the convenience of description below, the referenced "upper", "lower", "left" and "right" are the same as the upper, lower, left and right directions of the drawings themselves, and the "first", "second" and the like below are distinguished for the description and have no other special meanings.

[0027] Example 1

[0028] Reference Figure 1-2 The positioning device for the auxiliary pipe to pass through the rigid waterproof casing comprises a stainless steel clamp 1, a steel sheet 2, and a wedge positioning block 3. The wedge positioning block 3 is a wooden wedge, which is connected to the stainless steel clamp 1 through the steel sheet 2. The wooden wedge is provided with a socket on the side close to the stainless steel clamp 1; four steel sheets 2 are evenly connected to the stainless steel clamp 1 along the circumferential interval of the stainless steel clamp, and the four steel sheets 2 are arranged along the axial direction of the stainless steel clamp to point to the same side of the ring body of the stainless steel clamp 1. One end of the steel sheet 2 is welded to the stainless steel clamp 1, and the other end is inserted into the socket of the wooden wedge. Through the adaptation of the steel sheet 2 and the socket, the four wooden wedges are detachably mounted on the steel sheet 2, and the four wooden wedges are symmetrically distributed; the side of the four wooden wedges close to the axis of the stainless steel clamp is the first side 3 1, the side away from the axis of the stainless steel clamp is the second side 32, the first side 31 of the wooden wedge is parallel to the axis of the stainless steel clamp, the second side 32 of the wooden wedge forms an acute angle with its first side 31 in the counterclockwise direction, the edge of the first side 31 away from the stainless steel clamp 1 coincides with the edge of the second side 32 away from the stainless steel clamp 1, the coincident edges of the two side surfaces are perpendicular to the axis of the stainless steel clamp, the connection between the two side surfaces constitutes the flat sharp end of the wooden wedge, and the flat sharp ends of the four wooden wedges are all facing the side away from the stainless steel clamp 1; the first side surfaces 31 of the four wooden wedges are tangent to the outer side surface of the pipe 5 inserted into the stainless steel clamp 1, and the space enclosed by the first side surfaces 31 of the four wooden wedges through which the pipe 5 can pass is coaxial with the stainless steel clamp 1.

[0029] The implementation principle of Example 1 is:

[0030] By adjusting the clamp bolt 11, the ring diameter of the stainless steel clamp 1 is changed so that it can be set on pipes 5 of different sizes. The position of the stainless steel clamp 1 on the pipe 5 is adjusted to drive the wooden wedge from its flat sharp end to penetrate the gap between the pipe 5 and the rigid waterproof casing 4. When it reaches a certain degree, the first side 31 of the four wooden wedges tightly abuts against the outer side of the pipe 5, and the second side 32 tightly abuts against the edge of the port of the rigid waterproof casing 4. The four wooden wedges are evenly distributed, giving the pipe 5 extrusion pressure in different directions, clamping the pipe 5 in the middle position of the inner cavity of the rigid waterproof casing 4, making the pipe 5 coaxial with the rigid waterproof casing 4, and preventing the pipe 5 from abutting against the inner wall of the rigid waterproof casing 4.

[0031] Example 2

[0032] Reference Figure 3-4On the basis of Example 1, a plurality of triangular prism-shaped grooves are evenly spaced on the second side surface 32 of the wooden wedge; the length direction of the groove is parallel to the overlapping edges of the first and second sides, and passes through the two edges of the second side surface 32; the inner surface of the groove is composed of a groove bottom surface 321 and a groove side surface 322, the groove side surface 322 is perpendicular to the axis of the stainless steel clamp, and the groove bottom surface 321 is perpendicular to the groove side surface 322.

[0033] The implementation principle of Example 2 is:

[0034] When the wooden wedge is inserted from its flat and sharp end into the gap between the pipe 5 and the rigid waterproof sleeve 4 until it is tightly against the pipe, the edge of the port of the rigid waterproof sleeve 4 is inserted into the groove of the second side 32 of the wooden wedge and abuts against the side 322 of the groove; the bottom surface 321 of the groove is parallel to the first side 31 of the wooden wedge, which is convenient for the wooden wedge to penetrate the gap between the pipe 5 and the rigid waterproof sleeve 4 along the flat and sharp end; the side 322 of the groove is perpendicular to the axis of the stainless steel clamp 1, that is, perpendicular to the length direction of the pipe 5 inserted into the stainless steel clamp 1; when the pipe 5 is inserted into the rigid waterproof sleeve 4 along its length direction, the side 322 of the groove of the wooden wedge of the stainless steel clamp 1 placed on the pipe 5 is perpendicular to the length direction of the rigid waterproof sleeve 4; therefore, the edge of the port of the rigid waterproof sleeve 4 abuts against the side 322 of the groove, giving the pipe 5 additional support force to prevent the pipe 5 from tilting or sagging in the rigid waterproof sleeve 4.

[0035] Example 3

[0036] Reference Figure 2 , using the positioning device provided in implementation 1 or 2 to assist the pipe to pass through the rigid waterproof casing, including the following steps: 1) selecting a suitable wooden wedge according to the size of the pipe 5 and the rigid waterproof casing 4, and sleeve the wooden wedge on the steel sheet 2; 2) passing one end of the pipe 5 through the rigid waterproof casing 4 to a suitable length, sleeve the stainless steel clamp 1 on the pipe 5, so that the stainless steel clamp 1 is located on the outside of one end of the rigid waterproof casing 4, push the stainless steel clamp 1 so that four wooden wedges pass through the rigid waterproof casing 4 from its flat and sharp ends, and rotate the stainless steel clamp 1 in the process of pushing the stainless steel clamp 1 so that one of the wooden wedges is located directly below the pipe 5, and continue to push. 1) Move the stainless steel clamp 1 to the first side 31 of the four wooden wedges tightly against the outer side of the pipe 5 and the second side 32 of the four wooden wedges tightly against the edge of the port of the rigid waterproof sleeve 4, tighten the clamp bolts 11 to fix the position of the stainless steel clamp 1 on the pipe 5. At this time, the pipe 5 is located in the middle of the rigid waterproof sleeve 4 and is coaxial with the rigid waterproof sleeve 4; 3) Install the pipe support and hanger to fix the position of the pipe 5. After the pipe support and hanger is installed, loosen the clamp bolts 11, remove the stainless steel clamp 1 from the pipe 5, and then remove the four wooden wedges from the stainless steel clamp 1; 4) Waterproof the gap between the pipe 5 and the rigid waterproof sleeve 4.

[0037] The implementation principle of Example 3 is:

[0038] After the pipe 5 passes through the rigid waterproof casing 4, the pipe 5 may abut against the inner wall of the rigid waterproof casing 4, and a gap will be left at the abutment point after the joint is twisted, affecting the waterproof function of the joint. Therefore, by setting a positioning device on the pipe 5, the pipe 5 and the rigid waterproof casing 4 are made coaxial to prevent the pipe 5 from abutting against the rigid waterproof casing 4; the waterproof performance of the joint after such setting is more superior.

[0039] By placing one of the wooden wedges directly below the pipe 5 , the positioning device can better perform the function of supporting the pipe 5 .

[0040] Example 4

[0041] On the basis of Example 3, the following changes are made to step 2): one end of the pipe 5 is passed through the rigid waterproof sleeve 4 to an appropriate length, and the stainless steel clamps 1 of the two positioning devices are sleeved on the pipe 5, and the two stainless steel clamps 1 are respectively located on the outside of the two ends of the rigid waterproof sleeve 4, and the flat and sharp ends of the four wooden wedges on the two stainless steel clamps 1 are arranged opposite to each other, all facing the rigid waterproof sleeve 4; the two stainless steel clamps 1 are pushed so that the wooden wedges on them respectively pass through the rigid waterproof sleeve 4 from their flat and sharp ends, and in the process of pushing the two stainless steel clamps 1, the two stainless steel clamps 1 are rotated so that one of the wooden wedges on the two stainless steel clamps 1 is located directly below the pipe 5, and the push is continued until the first side surfaces 31 of the four wooden wedges on the two stainless steel clamps 1 are tightly against the outer side surface of the pipe 5 and the second side surfaces 32 of the four wooden wedges are tightly against the port edge of the rigid waterproof sleeve 4, and at this time, the clamp bolts 11 are tightened to fix the positions of the two stainless steel clamps 1 on the pipe 5.

[0042] The implementation principle of Example 4 is:

[0043] The stainless steel clamps 1 of the two positioning devices are respectively arranged at the two ends of the rigid waterproof sleeve 4, and the wooden wedges thereon clamp the pipe material 5 to prevent the pipe material 5 from tilting or sagging and then abutting against the inner wall of the rigid waterproof sleeve 4 when the positioning device is only arranged on the outside of one end of the rigid waterproof sleeve 4. This arrangement is particularly suitable for pipe materials 5 with higher density and heavier weight.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
