Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a device for searching buried pipes. Background Art

[0002] To ensure the seismic capacity of a building masonry wall, when the length of the masonry wall exceeds a certain value, tie bars need to be set in the masonry wall. Tie bars refer to the steel bars that connect the post-masonry and concrete components together according to certain structural requirements by means of connection methods such as post-inserted bars, embedded bars, and binding. The common practice in the prior art is as follows: positioning holes on the reinforced concrete column → drilling holes → clearing holes → injecting glue → implanting bars → extending the steel bars. The drilling depth requirement is > 100 mm and > 10d. After drilling, the dust in the bar-implanting hole is blown out with an air compressor or other equipment, and then the bar-implanting hole is wiped clean with a brush or cotton wool dipped in acetone. However, during construction, it is easy for the drill bit to hit the internal steel bars in the concrete when drilling, and it is necessary to change the position and reposition the drilling. In addition, there are also situations that affect the quality and efficiency of bar implantation, such as insufficient drilling depth, large dust during drilling, and incomplete cleaning of the dust in the hole. Therefore, it is necessary to improve the prior art. Summary of the Utility Model

Detailed Description of the Embodiment

[0024] The embodiments of the present disclosure will be described in detail below with reference to the drawings.

[0025] The following describes the embodiments of the present disclosure through specific examples. Those skilled in the art can easily understand the other advantages and effects of the present disclosure from the content disclosed in this specification. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. The present disclosure can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present disclosure without creative efforts belong to the scope protected by the present disclosure.

[0026] The utility model discloses a pipe pre-embedded pipe-finding device, which is applied to the construction of tie bars in a reinforced concrete masonry wall. It includes a pre-embedded pipe 2 and a pipe-finding structure. A guiding hole 205 is provided on the pre-embedded pipe 2. The pre-embedded pipe 2 is bundled on the steel bars and buried in the concrete masonry wall. The pipe-finding structure is detachably connected to the pre-embedded pipe 2 and closes the orifice of the guiding hole 205 after connection. After the concrete masonry wall is poured, the pipe-finding structure is used to locate the position of the pre-embedded pipe, and the pipe-finding structure is removed. The orifice of the guiding hole 205 is opened, and the guiding hole 205 serves as a rebar planting hole.

[0027] Further, as an embodiment of the present application, the pre-embedded pipe 2 includes an anchoring steel plate 201 and a pipe body 202. The pipe body 202 is vertically and fixedly arranged on the anchoring steel plate 201. The guiding hole 205 is arranged in the pipe body 202 and the orifice faces away from the anchoring steel plate 201. After the concrete is poured, the anchoring steel plate 201 and the pipe body are buried in the concrete masonry wall. Since the area of the anchoring steel plate 201 is large, the anti-pulling force of the rebar planting is increased, and the rebar planting efficiency is improved.

[0028] Further, the guiding hole 205 is arranged as an internal thread structure. The rebar to be implanted is arranged as an external thread, and the rebar is threadedly connected to the guiding hole 205 (i.e., the rebar planting hole), replacing the existing technology of bonding with glue, making the connection between the rebar and the guiding hole more firm, and further increasing the anti-pulling force of the rebar planting.

[0029] The pipe-finding structure corresponding to the above pre-embedded pipe 2 is as Figure 4As shown in the figure, the hole - finding structure includes a hole - finding nail 5 and a spring 6. The hole - finding nail 5 includes a hole - finding nail cap 503, a guiding ring 501, and a hole - finding nail rod 502 that are fixedly arranged in sequence. The hole - finding nail cap 503 is placed outside the pipe body 202, and its outer diameter is larger than the outer diameter of the pipe body 202. One end of the pipe body 202 away from the anchoring steel plate 201 is provided with a placement groove. The guiding ring 501 is placed in the placement groove and can reciprocate along the axial diameter of the pipe body 202 in the placement groove. The depth of the placement groove is larger than the height of the guiding ring 501. The spring 6 is placed in the guiding hole 205, with one end abutted against the bottom of the pipe body 202 and the other end abutted against the guiding ring 501. The hole - finding nail rod 502 is placed inside the spring 6.

[0030] During use, the embedded pipe 2 is tied to the structural steel bars, and the spring 6 and the hole - finding nail 5 are sequentially placed into the guiding hole 205. Since the outer diameter of the hole - finding nail cap 503 is larger than the outer diameter of the pipe body 202, the hole - finding nail cap 503 remains outside the guiding hole 205. At this time, the spring 6 is stuck between the guiding ring 501 and the anchoring steel plate 201 and is in a compressed state. The spring 6 presses the hole - finding nail cap 503 tightly against the template 4. After pouring the concrete and it solidifies, the template 4 is removed. Due to the action of the spring 6, when there is no template 4 to resist, the spring 6 pops the hole - finding nail 5 out of the guiding hole 205, and the hole - finding nail 5 and the spring 6 are taken out, and the hole - making is completed.

[0031] In the hole - making process of this application, there is no need to drill holes, and no dust will be left in the holes. Since the hole positions are fixed before pouring, there will be no situation of inaccurate positioning either.

[0032] The diameter of the hole - finding nail rod 502 is smaller than the inner diameter of the spring 6, and the outer diameter of the spring 6 is smaller than the inner diameter of the guiding hole 205. The diameter of the guiding ring 501 of the hole - finding nail is larger than the diameter of the spring 6. This setting can make the hole - finding nail rod 502 easily inserted into the spring 6, and make the spring 6 stuck between the guiding ring 501 and the anchoring steel plate 201. When installing, the template 4 presses the hole - finding nail 5 into the guiding hole 205, and tightly abuts the hole - finding nail cap 503 against the top of the pipe body 202 to prevent the concrete slurry from covering the guiding ring 501 during pouring.

[0033] The outer diameter of the hole - finding nail cap 503 is larger than the outer diameter of the pipe body 202 and is tightly fitted with the top of the pipe body 202. This setting can make it so that during formwork sealing and concrete pouring, even if the embedded pipe 2 is inclined and cannot fit well with the template, the hole - finding nail 5 can still be in a fitting state with the embedded pipe 2, making the hole - finding nail cap 503 block the guiding hole 205 and preventing the concrete slurry from flowing into the embedded pipe 2.

[0034] Further, as the second implementation mode of the present application, the embedded pipe 2 includes an anchor plate 201 and a pipe body 202. The pipe body 202 is vertically and fixedly arranged on the anchor plate 201. A guiding hole 205 is arranged in the pipe body 202 and the orifice faces away from the anchor plate 201. A retaining port 204 is arranged at one end of the pipe body 202 away from the anchor plate 201. The inner diameter of the retaining port 204 is larger than that of the guiding hole 205, so that a boss is formed between the retaining port 204 and the guiding hole 205. At least one prying opening 203 is arranged on the retaining port 204, and the prying opening 203 extends to the position of the boss.

[0035] The pipe-finding mechanism matching with the second type of embedded pipe 2 includes a magnetic chip plug 7 and an iron powder box 8. The magnetic chip plug 7 is a high-strength magnet and is snap-fitted in the retaining port 204 without clearance. The magnetic chip plug 7 is a high-strength magnet, and its bottom fits with the boss. The iron powder box 8 is filled with magnetic metal powder 802. It can be one or a combination of two or more of magnetic materials such as iron powder, cobalt powder, nickel powder, etc.

[0036] The magnetic chip plug 7 is a cylinder, and its outer diameter dimension is larger than the diameter of the guiding hole 205 and smaller than the diameter of the retaining port 204. This setting can make the magnetic chip plug 7 block the orifice of the embedded pipe 2 to prevent the concrete slurry from entering the embedded pipe 2 and polluting the inside of the embedded pipe 2.

[0037] Further, the iron powder box 8 is made of a transparent material, such as acrylic, plastic, etc. The box is divided into several compartments 801. Taking 3×3 compartments as an example, as Figure 7 shown. The magnetic metal powder 802 is filled in the compartments 801. During use, the embedded pipe 2 is fixed on the steel bar 3, and the magnetic chip plug 7 is plugged into the orifice of the embedded pipe 2. After the formwork 4 is removed, the iron powder box 8 is moved up and down on the wall surface of the concrete masonry wall near the orifice of the embedded pipe 2. Under the action of the strong magnet of the magnetic chip plug 7, the magnetic metal powder 802 inside the compartment 801 will have corresponding movements. According to the density of the magnetic metal powder 802, the position of the orifice of the embedded pipe 2 can be quickly found. After knocking off the concrete outside the magnetic chip plug 7 with a small hammer, the magnetic chip plug 7 is pried out from the prying opening 203 with a flat screwdriver, and the hole making is completed.

[0038] Further, the iron powder box 8 is composed of a hollow cuboid transparent material, and is internally divided into multiple compartments (which can be various combinations such as 3×3 or 4×4), and is filled with an appropriate amount of magnetic metal powder 802. This setting is convenient for workers to observe when the magnetic metal powder 802 has movements, and can better and faster find the position of the embedded pipe, saving time.

[0039] The specific use process of the present utility model is: positioning → installing the embedded pipe → installing the spring and the hole-finding nail (installing the magnetic chip plug) → pouring concrete → curing the concrete → removing the formwork → taking out the hole-finding nail (magnetic chip plug) → injecting glue → implanting steel bars → lengthening the steel bar. As Figure 1 、 2As shown, compared with traditional construction methods, the significant advantages of the present utility model are as follows: There is no need for experienced drilling workers to drill holes. After positioning, ordinary workers can also complete the operation well; Workers do not need to drill holes in concrete walls, especially in hard reinforced concrete columns; There is no need to drill holes in the formwork; The drilling depth is guaranteed; A greater uplift force can be provided under the same anchorage length. It saves labor and improves work efficiency.
