Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the corrugated pipes with bonded prestressed structural reserved channels continuously arranged on the same surface and in the same direction are not easy to locate and fix, and the construction is time-consuming. The conventional fixing device has high material input and cannot be handled well to improve the construction efficiency. In order to reduce the cost of measures and other issues, on the basis of the original bellows positioning and fixing, the bellows fixing and positioning device with bonded prestressed structure is continuously installed on the same surface in the same direction (horizontal or vertical direction) and innovated and fixed. Improvement, providing a prestressed bellows fixing device and method capable of fixing and positioning multiple bellows at one time, and positioning quickly and accurately

Embodiment 1

[0019] Such as figure 1 As shown, it is a structural schematic diagram of the device. The left part of the pool body wall 1 structure of the airtight pool is equidistantly arranged with the first main rib structure 2 arranged in parallel, and the first main rib structure 2 constitutes the thickness of the protective layer. The right part of the pool body wall The second main reinforcement structure 3 and the corrugated pipe fixing reinforcement device 4 arranged in parallel are arranged at equal intervals. The bellows fixing reinforcement device 4 and the outer wall of the pool body 5 constitute the distance of the isolation layer. The thickness of the structure includes the thickness of the protective layer and the distance of the isolation layer. The first The upper and lower parts of the main reinforcement structure 2 are respectively connected to the upper and lower reinforcement bars of the second main reinforcement structure through I-shaped steel bars 6, and the bellows ...

Embodiment 2

[0023] This device was improved and summarized during the construction process of the sludge digestion tank of the Kunming sludge disposal project. Since the digestion tank is constructed by the bonded prestressed sliding form method, the positioning of concrete, steel bars and corrugated pipes and fixed construction time and sliding are required. The mold lifting time is matched, the vertical spacing of prestressed steel bars is designed to be 25cm-50cm, and the distance from the center of the bellows to the outer pool wall is 11cm. The design requires that the construction positioning error of the bellows should not exceed 5mm. According to the specific requirements of the prestressed bellows, combined with the existing technical conditions, the positioning and fixing of the prestressed bellows were tested, optimized and improved, and implemented after the improvement. The implementation effect was satisfactory and the expected goal was achieved.

Abstract

The invention relates to the technical field of corrugated pipe fixing devices and discloses a prestressed corrugated pipe fixing device and method for rapid and accurate positioning. First main reinforcement structures which are arranged in parallel are arranged at the left part of a pool wall structure at equal intervals so as to form thickness d1 of a protective layer; second main reinforcement structures which are arranged in parallel at equal intervals and a corrugated pipe fixed steel reinforcement device are arranged at the right part of the pool wall; a designed isolation layer distance d2 is formed between the corrugated pipe fixed steel reinforcement device and the external wall of a pool; the upper parts and the lower parts of the first main reinforcement structures are respectively connected with reinforcements at the upper parts and the lower parts of the second main reinforcement structures through I-shaped reinforcements; the corrugated pipe fixed steel reinforcement device is connected with the I-shaped reinforcements phi22 together by adopting round steel phi8; the prestressed corrugated pipe fixing device is welded on the joint of the corrugated pipe fixed steel reinforcement device through two upper and lower pieces of round steel with different lengths according to the outer diameters of corrugated pipes and the designed vertical distance of prestressed reinforcements. The prestressed corrugated pipe fixing device and method have the advantages that the machining operation is simple, the construction efficiency is high, time spent on mounting a template and connecting and binding the reinforcements is shortened, and the corrugated pipe mounting and positioning time is reduced.

Description

[technical field] [0001] The invention relates to the technical field of concrete structure bellows fixing devices, specifically, it is applied to the prestressed structure of structural bellows with multi-layer and multi-channel prestressing on the same structural surface, and is a fast and accurate positioning, fixing device and bellows. Construction fixed positioning method. [Background technique] [0002] Prestressed bellows is a key process in the construction of prestressed structures. In the existing prestressed structures, the conventional positioning of bellows with bonded prestressed tendon channels is mainly done by welding and fixing the main reinforcement with a well-shaped device or by binding with iron wires. Fixing, the traditional positioning method has problems such as long construction time, low construction efficiency, large material consumption, inaccurate positioning, and weak positioning. Regarding the positioning and fixing of continuous multi-layer ...
