Abstract
Description
Technical Field
[0001] The utility model relates to a fastener, belonging to the field of grouting for prestressed ducts of continuous beams, and particularly relates to an integrated fastener of a corrugated pipe joint and an exhaust pipe. Background Technique
[0002] With the gradual development of the construction engineering industry, more and more projects involve the construction of continuous beams. In order to improve the durability of continuous beams, prestressed projects are essential. The prestressed ducts usually arch in the beam body, and the grouting port of the prestressed duct is located at the lowest point of the prestressed duct. After the prestressed tensioning is completed, grouting construction is carried out through the grouting port of the prestressed duct. When the other end of the prestressed duct discharges slurry, the prestressed ducts at higher positions have the situation of incomplete grouting, which will affect the durability and safety of the prestressed structure.
[0003] Chinese Patent with application number 202120557103.3 and application date of March 18, 2021 discloses a prestressed corrugated pipe exhaust hole device for continuous beam construction, including an exhaust pipe, the exhaust pipe is connected to a pipe attachment component, the pipe attachment component includes a connecting plate that fits with the prestressed corrugated pipe, an exhaust hole corresponding to the position of the exhaust reserved hole on the prestressed corrugated pipe is opened on the connecting plate, an exhaust connecting outer pipe is provided at the exhaust hole, one end of the exhaust pipe is communicated with the exhaust connecting outer pipe, and the other end of the exhaust pipe is closed by an exhaust control valve. Although this design can achieve the exhaust effect during the grouting process, it still has the following defects:
[0004] This design requires pre-opening an exhaust hole at the installation position of the corrugated pipe. Since the corrugated pipe is a curved surface structure, opening an exhaust hole on the corrugated pipe easily leads to an irregular shape of the exhaust hole, resulting in poor sealing at the connection between the exhaust hole and the exhaust pipe, and ultimately causing slurry leakage from the corrugated pipe and the adverse consequence of blockage of the prestressed duct.

When grouting, the air in the fastener is discharged from the exhaust pipe. The advantages of the utility model also include:
[0024] First: There is no need to drill holes in the bellows. The exhaust holes and the exhaust pipe have been set, and the connection between the exhaust pipe and the connecting pipe is stable, so slurry leakage will not occur here; the left joint is tightly connected with the bellows, and the right joint is tightly connected with the bellows, so good sealing spaces are formed between the left joint and the bellows and between the right joint and the bellows, and slurry leakage accidents will not occur between the left joint and the bellows and between the right joint and the bellows either;
[0025] Second: The exhaust pipe is fixed to the connecting pipe, that is, the insertion depth of the exhaust pipe is fixed, avoiding the situation that the exhaust pipe is inserted too deep and affecting the threading of the prestressed steel strand, that is, it cooperates well with other processes;
[0026] Third: The exhaust pipe is made of a soft material. One end of the exhaust pipe is fixed, and the other end can move in multiple directions. That is, it can extend more than five centimeters above the beam surface elevation according to the specific arrangement of the beam body steel bars. In this way, it can ensure the air outflow effect in the fastener, make the slurry in the exhaust pipe below the beam surface full and compact, and can also avoid the concrete covering the exhaust pipe, resulting in the failure of the exhaust pipe. Therefore, the exhaust effect is better;
[0027] Fourth: One side of the left joint, the connecting pipe and the right joint is a hinge structure, and the other side is a detachable structure. Therefore, the left joint, the connecting pipe and the right joint can be turned upwards to achieve the opening effect. When opening, it is easier to insert the bellows into the left joint and the right joint. Therefore, the utility model is convenient to use;
[0028] Therefore, the utility model will not cause slurry leakage and cooperates well with other processes.

The length of the connecting pipe is 3 to 5 cm. During application, an overlapping distance of 15 to 30 cm can ensure a tight connection between the left joint and the corrugated pipe, and between the right joint and the corrugated pipe. The connecting pipe is of a straight cylinder structure, and its length needs to be greater than the diameter of the exhaust pipe, so as to stably connect the exhaust pipe and the connecting pipe. Therefore, the connection of the present utility model is stable.
[0030] 3. In the integrated fastener of the corrugated pipe joint and the exhaust pipe of the present utility model, left tie straps are arranged at intervals on the left joint.

Specific embodiments
[0044] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0045] In an embodiment of the present application, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 12 , a corrugated pipe joint and an exhaust pipe integrated fastener, the fastener includes a left joint 1, a connecting pipe 2, an exhaust pipe 22 and a right joint 3; one end of the left joint 1 is used for sleeving the end of the corrugated pipe 4, the other end of the left joint 1 is integrally communicated with one end of the connecting pipe 2, a connecting hole 21 is provided at the top of the connecting pipe 2, the connecting hole 21 is integrally communicated with one end of the exhaust pipe 22, the other end of the connecting pipe 2 is integrally communicated with one end of the right joint 3, and the other end of the right joint 3 is used for sleeving the end of the corrugated pipe 4.

Then put the right joint 3 on the outside of the bellows 4 on the other side to firmly connect the right joint 3 and the bellows 4. Then extend the exhaust pipe 22 out of the beam surface along the specific arrangement of the beam reinforcement, and make the exhaust outlet 221 five centimeters higher than the elevation of the beam surface. Then grout into the bellows 4. The slurry flows from the bellows 4 into the left joint 1, then into the connecting pipe 2, then into the right joint 3, and then back into the bellows 4. During the above process, the air is squeezed by the slurry and flows upward into the exhaust pipe 22, and then the air is discharged from the exhaust outlet 221 to avoid the influence of air on the grouting effect and make the grouting in the bellows 4 and the fasteners full and dense.
[0047] In another embodiment of the present application, refer to Figure 1 、 Figure 5 The left joint 1 includes a symmetrically arranged left upper end 11 and a left lower end 12. The left upper end 11 and the left lower end 12 enclose a tubular shape. One side of the left upper end 11 is hinged to one side of the left lower end 12, and the other side of the left upper end 11 is detachably connected to the other side of the left lower end 12. The connecting pipe 2 includes a symmetrically arranged upper pipe 23 and a lower pipe 24. The upper pipe 23 and the lower pipe 24 enclose a tubular shape. One side of the upper pipe 23 is hinged to one side of the lower pipe 24, and the other side of the upper pipe 23 is detachably connected to the other side of the lower pipe 24. The right joint 3 includes a symmetrically arranged right upper end 31 and a right lower end 32. The right upper end 31 and the right lower end 32 enclose a tubular shape. One side of the right upper end 31 is hinged to one side of the right lower end 32, and the other side of the right upper end 31 is detachably connected to the other side of the right lower end 32. Both ends of the upper pipe 23 are integrally connected to the left upper end 11 and the right upper end 31 respectively. Both ends of the lower pipe 24 are integrally connected to the left lower end 12 and the right lower end 32 respectively. Preferably, the detachable connection is a hinge connection. Preferably, the detachable connection is a snap connection.
[0048] During application, first separate the detachable connection side of the left upper end 11 and the left lower end 12. Since the left upper end 11 is integrally connected to the upper pipe 23 and the right upper end 31 in sequence, and the left lower end 12 is integrally connected to the lower pipe 24 and the right lower end 32 in sequence, the detachable connection side of the upper pipe 23 and the lower pipe 24 is separated, and the detachable connection side of the right upper end 31 and the right lower end 32 is separated. Then put the bellows 4 into the left lower end 12, and then put another bellows 4 into the right lower end 32. Then connect the detachable side of the left upper end 11 and the left lower end 12, the detachable side of the upper pipe 23 and the lower pipe 24, and the detachable side of the right upper end 31 and the right lower end 32, and then the left joint 1 and the bellows 4 inside it can be fixed, and the right joint 3 and the bellows 4 inside it can be fixed.
[0049] In another embodiment of the present application, refer toFigure 1 , Figure 2 , Figure 3 , Figure 4 , the length of the left joint 1 is greater than or equal to 15 cm and less than 30 cm; the length of the right joint 3 is greater than or equal to 15 cm and less than 30 cm.
[0050] Further, referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , the connecting pipe 2 is of a straight tube type, and the length of the connecting pipe 2 is 3 to 5 cm to ensure a good fit between the connecting pipe 2 and the exhaust pipe 22.
[0051] During application, when inserting the corrugated pipe 4 into the left joint 1, the overlapping distance between the corrugated pipe 4 and the left joint 1 is greater than or equal to 15 cm and less than 30 cm. In this way, the connection between the corrugated pipe 4 and the left joint 1 can be made tight, so as to obtain a good sealing effect to prevent slurry leakage accidents; if the overlapping distance between the corrugated pipe 4 and the left joint 1 is less than 15 cm, the sealing effect between the corrugated pipe 4 and the left joint 1 is not good, which may cause slurry leakage. If the overlapping distance between the corrugated pipe 4 and the left joint 1 is greater than 30 cm, the left joint 1 is too long, resulting in material waste; when inserting the corrugated pipe 4 into the right joint 3, the overlapping distance between the corrugated pipe 4 and the right joint 3 is greater than or equal to 15 cm and less than 30 cm. In this way, the connection between the corrugated pipe 4 and the right joint 3 can be made tight, so as to obtain a good sealing effect to prevent slurry leakage accidents; if the overlapping distance between the corrugated pipe 4 and the right joint 3 is less than 15 cm, the sealing effect between the corrugated pipe 4 and the right joint 3 is not good, which may cause slurry leakage. If the overlapping distance between the corrugated pipe 4 and the right joint 3 is greater than 30 cm, the right joint 3 is too long, resulting in material waste. The connecting pipe 2 is of a straight tube type, which is convenient for setting a circular connection hole 21, so that the shape of the connection hole 21 matches the shape of the exhaust pipe 22 to obtain a good sealing effect. The length of the connecting pipe 2 needs to be greater than the diameter of the exhaust pipe 22, so the length of the connecting pipe 2 is greater than 3 cm, and the length of the connecting pipe 2 needs to be less than 5 cm to avoid the connecting pipe 2 conflicting with the prestressed duct, thus affecting the grouting effect.
[0052] In another embodiment of the present application, referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , the left joint 1 is of a corrugated structure, and the right joint 3 is of a corrugated structure.
[0053] Further, referring to Figure 4 , Figure 5, the left joint 1 includes a plurality of left recesses 13, and a left cable tie 5 for fixing the left joint 1 and the corrugated pipe 4 is arranged on the left recess 13. The right joint 3 includes a plurality of right recesses 33, and a right cable tie 6 for fixing the right joint 3 and the corrugated pipe 4 is arranged on the right recess 33.
[0054] Further, referring to Figure 6 , Figure 7 , Figure 8 , the left cable tie 5 includes a left strip 51 and a left plug 52 fixed on the left recess 13. The left strip 51 is clamped with the left plug 52. The left strip 51 is located on the outer surface of the upper left recess 131, and the left plug 52 is located on the outer surface of the lower left recess 132.
[0055] Further, referring to Figure 6 , Figure 7 , Figure 8 , the left strip 51 is uniformly distributed with left stepped structures 511, and a left stepped hole 521 matching the left stepped structures 511 is arranged in the left plug 52. Therefore, the left stepped structures 511 can move unidirectionally in the left stepped hole 521.
[0056] Further, referring to Figure 9 , Figure 10 , Figure 11 , the right cable tie 6 includes a right strip 61 and a right plug 62 fixed on the right recess 33.

The right strip 61 is located on the outer surface of the upper right recess 331, and the right plug 62 is located on the outer surface of the lower right recess 332.
[0057] Further, referring to Figure 9 , Figure 10 , Figure 11 , the right strip 61 is uniformly distributed with right stepped structures 611, and a right stepped hole 621 matching the right stepped structures 611 is arranged in the right plug 62. Therefore, the right stepped structures 611 can move unidirectionally in the right stepped hole 621.
[0058] During application, both the left joint 1 and the right joint 3 are corrugated structures. Therefore, both the left joint 1 and the right joint 3 can form a good fit with the corrugated pipe 4, achieving the clamping effect between the left joint 1, the right joint 3 and the corrugated pipe 4. First, pass the free end of the left strip 51 through the left stepped hole 521 to the outside of the left stepped hole 521. At this time, the left stepped structure 511 slides through the left stepped hole 521 in sequence, and then pull the free end of the left strip 51 until the left strip 51 tightly connects the left upper end 11 and the left lower end 12. The left strip 51 and the left stepped hole 521 are ratchet structures. Therefore, the left strip 51 can only move unidirectionally in the left stepped hole 521, that is, the left strip 51 can only tighten the left upper end 11 and the left lower end 12, but cannot loosen the left upper end 11 and the left lower end 12. Then, pass the free end of the right strip 61 through the right stepped hole 621 to the outside of the right stepped hole 621. At this time, the right stepped structure 611 slides through the right stepped hole 621 in sequence, and then pull the free end of the right strip 61 until the right strip 61 tightly connects the right upper end 31 and the right lower end 32. The right strip 61 and the right stepped hole 621 are ratchet structures. Therefore, the right strip 61 can only move unidirectionally in the right stepped hole 621, that is, the right strip 61 can only tighten the right upper end 31 and the right lower end 32, but cannot loosen the right upper end 31 and the right lower end 32. One left tie strap 5 is provided at every other left recess 13, and one right tie strap 6 is provided at every other right recess 33. This can make the connection between the left recess 13 and the right recess 33 stable while minimizing the constraints of the left tie strap 5 and the right tie strap 6.
