Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a precast corrugated pipe reinforcement support device for precast T-beam steel cages. Background Technology

[0002] In prestressed concrete structures, the corrugated pipes installed inside the T-beam reinforcement cage mainly serve to provide channels for the prestressing tendons. The corrugated pipes are pre-embedded in the T-beam reinforcement cage before concrete pouring to form continuous and smooth channels, which facilitates the later insertion of prestressed steel strands or steel bundles. The corrugated structure can ensure the flexibility of the pipes to adapt to the shape of the T-beam reinforcement cage, and also avoid blockage of the channels during concrete grouting.

[0003] During concrete grouting and T-beam reinforcement cage hoisting, corrugated pipes are susceptible to displacement or compression deformation due to external forces. Positioning supports can firmly fix the corrugated pipes to the transverse reinforcement bars of the T-beam reinforcement cage, preventing the prestressing channel from twisting and ensuring the smooth passage of prestressing tendons and uniform stress transmission after grouting. Usually, positioning components are welded into the T-beam reinforcement cage to provide reinforcement support.

[0004] In the existing technology, when providing reinforcement support for corrugated pipes, the positioning frame is generally welded to the T-beam steel cage. However, after the corrugated pipe is inserted, it is in an arc-shaped structure with a low middle and high ends in the steel cage, which is inconvenient to insert and has poor support stability. Utility Model Content

[0005] The purpose of this invention is to provide a precast corrugated pipe reinforcement support device for precast T-beam steel cages, which is easy to insert and provides better support stability after reinforcement connection.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a precast corrugated pipe reinforcement support device for precast T-beam reinforcement cages, comprising a corrugated pipe body, wherein the corrugated pipe body is disposed inside the T-beam reinforcement cage, and a supporting steel bar is fixedly connected to the bottom of the corrugated pipe body along the length direction of the T-beam reinforcement cage. Each supporting steel bar is fixedly connected to two collars corresponding to one corrugated pipe body, and a positioning hole is opened at the top of the collar. An inverted U-shaped positioning frame is inserted into the two positioning holes and fixed by a fixing component. The positioning frame is sleeved on the corrugated pipe body.

[0007] Furthermore, an installation hole is provided on one side of the inner wall of the aforementioned positioning hole. A rod is slidably connected to the installation hole. A tension spring is sleeved on the rod. The two free ends of the positioning frame are provided with insertion holes that can be directly aligned with the rod. The two ends of the tension spring are respectively fixedly connected to the large end of the inner end of the rod and the opening of the installation hole. The two free ends of the positioning frame are provided with insertion holes that can be directly aligned with the rod. After the positioning frame is inserted into the positioning hole, the rod is inserted into the insertion hole.

[0008] Furthermore, the aforementioned fixing component includes a rotating shaft rotatably connected to a semi-circular ring, the lower end of which is helically connected to a bolt, and a threaded hole is provided at the bottom of the collar, with the bolt helically connected to the threaded hole.

[0009] Furthermore, a protective layer is fixedly connected to the outer wall of the aforementioned positioning frame, and an anti-slip strip is fixedly connected to the top inner side of the protective layer, with anti-slip textures provided on the two vertical sections of the protective layer.

[0010] Furthermore, the aforementioned anti-slip texture is in the shape of a vertically curved arc.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1) This utility model uses the inverted U-shaped design of the positioning frame to lock into the corrugated pipe body for limiting, and inserts it into the positioning hole of the collar and fixes it with a fixing component, which greatly improves the support stability of the corrugated pipe. Moreover, after inserting the corrugated pipe, the inverted U-shaped positioning frame is installed, which provides a large space for inserting the pipe and makes it easier to insert the pipe. 2) The insertion rod automatically engages with the insertion hole under the action of the spring to achieve locking, further improving the connection reliability and stability of the positioning frame; 3) The rotating ring of the fixed component covers half of the collar area by rotating the shaft and is tightened by screwing bolts into the screw holes, which improves the reinforcement stability of the bellows body, makes the installation convenient and reliable, and the automatic locking of the plug rod provides a positioning function for the bolts on the rotating ring to be accurately screwed into the screw holes. 4) The anti-slip strips on the top of the protective layer are inserted into the corrugated grooves of the corrugated pipe, and the irregular arc-shaped anti-slip patterns on the sides enhance the friction between the positioning frame and the corrugated pipe body in all directions, effectively suppressing construction vibration displacement and improving the stability of the reinforcement.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] Example 1: Refer to Figures 1-3 A precast corrugated pipe reinforcement support device for precast T-beam reinforcement cages includes a corrugated pipe body 1, which is installed inside the T-beam reinforcement cage 2. Supporting reinforcing bars 3 are fixedly connected to the bottom of the corrugated pipe body along its length in the T-beam reinforcement cage 2. The number of collars 5 on the supporting reinforcing bars 3 is determined according to the number of corrugated pipe bodies 1 (four in this embodiment, for two corrugated pipes). If two sets of corrugated pipe bodies 1 are installed inside the T-beam reinforcement cage 2, then four sets of collars 5 are installed on the supporting reinforcing bars 3. Two sets of collars 5, in conjunction with a positioning frame 4, provide reinforcement and positioning functions for one set of corrugated pipe bodies 1. The supporting reinforcing bars 3 are fixedly connected to… There are two collars 5 corresponding to a corrugated pipe body. The top of the collar 5 is provided with a positioning hole 6. A positioning frame 4 is provided on the outside of the corrugated pipe body 1. The positioning frame 4 is in the shape of an inverted U. The U shape makes it easy to be inserted into the corrugated pipe body 1 to limit its position. The two free ends of the positioning frame 4 are inserted into the positioning hole 6 and fixed by a fixing component. The positioning frame 4 is sleeved on the corrugated pipe body 1. The inverted U-shaped design of the positioning frame is used to insert into the corrugated pipe body to limit its position. It is inserted into the positioning hole of the collar and fixed by a fixing component, which greatly improves the support stability of the corrugated pipe. Moreover, after the corrugated pipe is inserted, the inverted U-shaped positioning frame is installed, which provides a large space for pipe insertion and makes pipe insertion easier.

[0016] Specifically, to improve the insertion stability of the positioning frame, an installation hole 7 is provided on one side of the inner wall of the positioning hole 6. An insertion rod 9 is slidably connected to the installation hole 7. The end of the insertion rod 9 facing the positioning hole is set as a ball head. The insertion rod 9 penetrates into the interior of the positioning hole 6 and is arranged in a transverse T-shape. A tension spring 10 is sleeved on the insertion rod 9. In its free state, the tension spring can keep the ball head 3-5mm inside the positioning hole. The two free ends of the positioning frame are set as a conical structure with a smaller inner end and a larger outer end, facilitating the smaller end to enter the positioning hole first, and then the insertion rod is pushed by the conical surface. Pushed into the mounting hole, one end of the tension spring 10 is fixedly connected to the large end of the insertion rod 9, and the other end of the spring 10 is fixedly connected to the opening of the mounting hole 7. Under the elastic action of the tension spring 10, the end of the insertion rod 9 can be placed inside the positioning hole 6. The two free ends of the positioning frame 4 are provided with insertion holes 8 that can be directly aligned with the insertion rod. After the positioning frame 4 is inserted into the positioning hole 6, the insertion rod 9 can be inserted into the insertion hole 8. Through the locking mechanism of the insertion hole, the insertion rod and the tension spring, the positioning frame can play a better locking role, improving the reliability and stability of the connection.

[0017] Reference Figures 3-5 The fixing assembly includes a rotating shaft 11, a rotating ring 12, a bolt 13, and a screw hole 14. For the two bellows bodies 1, at least two sets of rotating rings 12 are provided, which are mirror images of the two ends of the rotating shaft 11 along its length. The rotating ring 12 can fit against the surface of the collar 5, that is, the inner surface of the rotating ring 12 is adapted to the outer surface of the collar 5. The upper end of the rotating ring 12 is rotatably connected to the positioning frame 4 through the rotating shaft 11. The rotating ring 12 is semi-circular in shape. The lower end of the rotating ring 12 is screwed with a bolt 13. A screw hole 14 is provided at the bottom of the collar 5. The inner wall of the screw hole 14 is threadedly connected to the outer wall of the bolt 13. This fixing assembly further improves the connection reliability and stability of the positioning frame.

[0018] Reference Figure 5 A protective layer 15 is fixedly connected to the outer wall of the positioning frame 4. The protective layer 15 is made of metal and is welded to the positioning frame in a half-and-half structure. An anti-slip strip 16 is fixedly connected to the inner top of the protective layer 15. The anti-slip strip 16 is made of metal and can be inserted into the groove of the corrugated pipe, thereby increasing the friction between the protective layer 15 and the top of the corrugated pipe body 1. Anti-slip patterns 17 are provided on the two vertical sections of the protective layer 15. The anti-slip patterns 17 are vertically curved arcs. The curvature of the anti-slip patterns 17 is irregular, which further increases the friction between the side of the corrugated pipe body 1 and the positioning frame 4.

[0019] Working principle: When it is necessary to reinforce the corrugated pipe body 1, first insert the corrugated pipe body 1 into the T-beam reinforcement cage 2. The supporting steel bar 3 supports the corrugated pipe body. After inserting the corrugated pipe body, the collar 5 on the supporting steel bar 3 cooperates with the positioning frame 4 to position the corrugated pipe body 1. If there are two sets of corrugated pipe bodies 1 in the T-beam reinforcement cage 2, the four sets of collars 5 on the supporting steel bar 3 are arranged in pairs. With the cooperation of the inverted U-shaped positioning frame 4, the U-shaped structure can easily insert the corrugated pipe body 1 and limit its position. After the positioning frame 4 is inserted into the positioning hole 6 at the top of the collar 5, under the elastic action of the tension spring 10, the insertion rod 9 automatically inserts into the insertion hole 8 on the outer wall of the positioning frame 4, realizing the initial fixation of the positioning frame 4 and the collar 5, and preventing the positioning frame 4 from falling off during use. Meanwhile, the positioning frame 4 further enhances the connection stability through the fixing components. Specifically, by rotating the rotating shaft 11, the rotating ring 12 is made to fit against the surface of the collar 5, covering the collar 5. Then, the bolt 13 is tightened to make it threaded into the screw hole 14, thereby firmly fixing the positioning frame 4 and the collar 5. In addition, the protective layer 15, anti-slip strips 16 and anti-slip textures 17 on the outer wall of the positioning frame 4 play a role. The anti-slip strips 16 on the protective layer 15 and the irregularly curved anti-slip textures 17 increase the friction between the positioning frame 4 and the corrugated pipe body 1 from multiple dimensions, effectively preventing the corrugated pipe body 1 from sliding during use, ensuring the stability and reliability of the entire reinforced support structure, and providing a long-lasting and stable reinforced support effect for the corrugated pipe body 1.
