Abstract
Description
Technical Field
[0001] The invention relates to the technical field of corrugated pipe fixing, in particular to a novel fixing device for a prestressed corrugated pipe. Background Art
[0002] In the rapid development of the construction industry, prestressing technology has been widely used. Prestressing technology is to enhance its compressive resistance and structural stability by applying pre-designed stress on the corrugated pipe. This technology plays a key role in many building structures, especially for structural parts that need to bear large loads.
[0003] As a key component in the implementation of prestressing technology, the fixing method of corrugated pipes is crucial. In view of the characteristics of corrugated pipes, traditional fixing methods may use specially designed prestressed anchors or clamps to ensure that the prestress can be effectively transferred to the pipe structure.
[0004] In post-tensioning construction, a corrugated pipe with a diameter larger than the prestressed steel bar is usually installed outside the prestressed steel bar. However, there are often some problems in conventional construction operations. For example, a common steel bar is generally used for positioning and then welded to the nearby steel bars. However, this method is usually difficult to weld and fix the inner steel bars. This results in the prestressed corrugated pipe being unable to be stably fixed in the specified position, which may affect the prestressing effect and stability of the entire structure.
[0005] Such situations as missing welding, missing or falling off of positioning reinforcement will not only bring inconvenience to construction, increase construction cost and time, but may also pose a potential threat to the quality and safety of the building structure.
[0006] Therefore, the development of a new type of prestressed corrugated pipe fixing device and method that can effectively solve these problems has important practical significance. It will help improve the construction quality and safety of building structures and promote the further development of prestressed technology applications in the construction industry.

[0054] Preferably, the first elastic member 8 is a tension spring. In this embodiment, the ends of the tension spring are fixed by welding. In other embodiments, a hook or other structure may be provided for connection and fixation, which is not specifically limited in the present invention. The hinged structures 12 are all made of ordinary steel plates 5 to reduce costs. The spring is embedded in the inner wall of the steel plate 5, and the connection method between the spring and the hinged movable part 6 can be to open a hole inside the hinged movable part 6 to embed the spring and then weld it to complete the installation.
[0055] Based on the above embodiments, in an optional embodiment of the present invention, as Figure 3 , Figure 4 and Figure 6 As shown, the hinged fixing member 13 is connected to the steel plate 5 through a first fastener 11. Preferably, the hinged member further comprises a first stud 9 connected to the steel plate 5. The hinged fixing member 13 is provided with a first screw hole matched with the first stud.
[0056] Specifically, a screw with threads on both sides of ordinary round steel is passed through the steel plate 5 in the middle of the steel plate 5 to form the first stud 9.

The first connecting member 10 is provided with a second screw hole. The second screw hole is used to engage with the hinged movable member 6 through a second fastener. Preferably, the side wall of the open sleeve 7 is provided with a protrusion or texture for increasing resistance. The protrusion or texture can increase the friction between the steel bar and improve the stability of the fixation.
[0058] Specifically, the sleeve component can be detachably connected to the hinge component through the first connecting member 10, so that one end of the new fixing device can be fixed to the internal longitudinal steel bar first, and then the other end can be fixed to the external longitudinal steel bar to avoid interference during installation.

[0061] Embodiment 2: The present application further provides a method for fixing a novel fixing device for a prestressed corrugated pipe, which is used to fix the novel fixing device for a prestressed corrugated pipe of embodiment 1 to a steel frame 1. The fixing method includes steps S1 to S9.
[0062] S1. Select the bent steel bars 4 according to the corrugated pipe 3 to be fixed.
[0063] S2. Select the steel plate 5 according to the distance between the longitudinal steel bars of the steel frame 1.
[0064] S3. Weld the bent steel bar 4 to the steel plate 5 so that a channel capable of being sleeved on the corrugated tube 3 is formed between the bent steel bar 4 and the steel plate 5.
[0065] Specifically, the length of the steel plate 5 can be adjusted according to the distance between the longitudinal reinforcements on site to improve the situation in which the welding cannot be fixed on the inner side of the reinforcement cage in the traditional method, instead of using ordinary reinforcements on site for positioning, which may cause the positioning reinforcement to be missing, missing, or falling off.
[0066] S4, joining the first hinge member and the second hinge member to the steel plate 5. Based on the above embodiment, in an optional embodiment of the present invention, step S4 specifically includes steps S41 to S44.
[0067] S41, performing the following steps on the first hinge member and the second hinge member respectively to join them to the steel plate 5.
[0068] S42, fixing the two ends of the first elastic member 8 of the hinged component to the hinged movable member 6 and the steel plate 5 respectively.
[0069] S43, engaging the first screw hole of the hinged fixing member 13 with the first stud 9 on the steel plate 5.
[0070] S44, fixing the hinged fixing member 13 by using the first fastening member 11.
[0071] Specifically, slots are provided on both sides of the steel plate 5, and the strong springs are installed on the slots of the steel plate 5 and welded first; after the installation is completed, the hinged fixing part 13 is connected to the first studs 9 on both sides of the steel plate 5; then the hinged fixing part 13 is fixed to the steel plate 5 by the first fastener 11.
[0072] S5. Engage the first sleeve member with the first hinge member.
[0073] S6. Extend the first sleeve member into the steel frame 1 and fix it to the internal longitudinal steel bars.

Extend the installed first sleeve member into the side away from the operating surface (i.e., the outer surface) of the steel frame 1 and fix it to the longitudinal steel bar. Since the structure adopts a tension spring, when the open sleeve 7 is in contact with the longitudinal steel bar during construction, the two sides of the first hinge member will open. When the first sleeve member is inserted into the longitudinal steel bar, due to the action of the tension spring, it is clamped inward so that the structure can be fixed.
[0075] S7. Place the second hinged member on both sides of the external longitudinal reinforcement.
[0076] S8. Fix the second sleeve member to the external longitudinal reinforcement.
[0077] S9. Fix the second sleeve member to the second hinge member.
[0078] When fixing the first sleeve member, the novel fixing device is inserted obliquely from the gap between the steel bars into the steel bar frame 1. Therefore, the second hinge member is still between the steel bars. At this time, the second hinge member is opened, and then the second hinge member is inserted into the corresponding longitudinal steel bar, and then the open sleeve is installed.
[0079] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
