Description
Technical Field
The utility model relates to a technical field is assembled in the prefabricated of segment section, especially relates to a prefabricated device for reservation pore of segment section.
Background
The segment prefabrication and assembly construction process divides a beam body into a plurality of segments, and all the segments are manufactured one by one in a prefabrication factory and are connected into a whole on a construction site. The method has the advantages of wide application in bridge construction. However, in the construction process, a pore channel needs to be reserved and a beam end needs to be fixed, so that the penetration and tensioning work of the prestressed steel strand is influenced, and the importance is high. The traditional method generally adopts a pre-embedded corrugated pipe to form a hole or a drawn rubber rod to form a hole, the former cannot be reused, and cracks are easy to appear during the manufacturing of a section, so that slurry leakage and hole plugging are caused. The latter is easy to deform, is fussy to position in pore channel forming, is commonly used for forming pores by small prestress, has large mass and can not meet the requirements of people. Therefore, there is a need for a device for segment prefabrication of a pre-cast tunnel to solve the above problems.
Disclosure of Invention
The utility model discloses a solve above-mentioned problem, provide a prefabricated device for reservation pore of festival section.
The utility model adopts the following technical proposal: the utility model provides a prefabricated device for reserved hole of segment, including the rubber stick, rubber stick center department is provided with the through-hole, install supporting spring in the through-hole, still be provided with a plurality of tunnels on the rubber stick, a plurality ofly set up and use the through-hole to set up and evenly distributed as central ring, be provided with the inlayer gasbag in the tunnel, the inlayer gasbag is connected with tunnel surface bonding, be provided with the valve on the inlayer gasbag, the inlayer gasbag has connect aerating device and force pump through the valve, the inlayer gasbag is hollow pipeline structure, the inside reinforcing bar that is equipped with of inserting of inlayer gasbag.
Further, the supporting spring is an annular structure with the outer diameter being the same as the inner diameter of the through hole and is made of an elastic material.
Furthermore, a plurality of supporting springs are uniformly arranged along the through hole and are connected with the inner surface of the through hole in an adhesive mode.
Further, the inner diameter D of the through hole is larger than the inner diameter D of the pore channel.
The working principle is as follows: during the use, place outer rubber hollow tube, insert the inlayer gasbag, insert the reinforcing bar that the shape preparation was accomplished in the inlayer gasbag, utilize aerating device to aerify to the inlayer gasbag through the valve to monitor gasbag atmospheric pressure, inflation pressure reaches the predetermined value after, stops to aerify, concreting, treat the concrete shaping and after the maintenance, open the valve and lose heart, take out the inlayer gasbag earlier, take out rubber tube and spring at last.
Compared with the prior art, the utility model discloses following beneficial effect has:
1. through aerating device, the gasbag can closely meet with outer rubber tube, and contains the spring in the rubber tube way, forms the support, and non-deformable has solved the problem that traditional pulling out rubber tube is applicable to less prestressing force pore-forming.
2. The advantages of the traditional rubber rod are combined, the rubber pipeline and the spring have high elasticity, and are contracted in the radial direction when stressed in the axial direction, and the drawing is easier due to the existence of the air bag. The surface is smooth, and the hole wall is smooth. Can be used repeatedly, has long service life and low price. The problems of slurry leakage and the like are not easily caused in the concrete pouring process.
3. The inner layer air bag is in a hollow pipeline form and is connected with a reinforcing steel bar, and the reinforcing steel bar can be changed into a pore canal shape to help positioning. After the air bag leaks air, the reinforcing steel bar is easy to take out.
4. The traditional rubber rod is mostly in a solid or small hole form, and the mass can be reduced due to the existence of the air bag, so that the transportation is convenient.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention; based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1-3, a prefabricated device for reserving pore canal of segment, including rubber stick 1, rubber stick 1 center department is provided with through-hole 5, install supporting spring 4 in the through-hole 5, still be provided with a plurality of pore canals 7 on the rubber stick 1, a plurality of and pore canal 7 set up and use through-hole 5 as central annular setting and evenly distributed, be provided with inlayer gasbag 2 in the pore canal 7, inlayer gasbag 2 is connected with pore canal 7 surface bonding, be provided with valve 6 on the inlayer gasbag 2, inlayer gasbag 2 has connect aerating device and force pump through the valve, inlayer gasbag 2 is hollow pipeline structure, inlayer gasbag 2 is inside to be inserted and is equipped with reinforcing bar 3. The inner diameter D of the through hole 5 is larger than the inner diameter D of the porthole 7.
