Embodiment 1

[0029] like Figure 1-3 As shown, the present embodiment provides a device for rapidly securing a prestressed bellows, including a plurality of boom assemblies, determined by the length of the prestressed beam, in most cases, to add prestressed corrugations for five meters long prestressed beam 20 boom assemblies are required when tubing. The plurality of boom assemblies are suspended in the longitudinal direction of the prestressing beam, each of which includes a vertical boom 1 and a support tie rod 2, and the vertical boom 1 and the support tie rod 2 are made of C12 steel bars, support The pulley 2 is transversely distributed, and its own length is larger than the width of the prestressed beam. The upper end of the vertical boom 1 is perpendicular to the intermediate position of the support tie rod 2, and there are two upper and lower parallel distributions of the vertical boom 1, and the two crossbar 3 is thrown down from the vertical boom 1. "F" shape, the two crossbar 3 forms...

Embodiment 2

[0037] like Figure 4 As shown, the present embodiment provides a device for a rapid fixed prestressed bellows, and most of the structures are the same as in Example 1. Further, in the present embodiment, the vertical hanging lever 1 is The No. 1 rod 11 and the second rod 12 are composed, before construction, the No. 1 rod can be welded in the support crossbar to facilitate mass production. When the on-site construction, the second rod is directly stacked and then placed and then welded. In order to change the length of the overlap region, change the overall length of the vertical boom, more convenient and flexible.

Embodiment 3

[0039] like Figure 5 As shown, the present embodiment provides a device for a rapid fixed prestressed bellows, and most of the structures are the same as in Example 1. Further, in the present embodiment, the vertical hanging lever 1 is The No. 1 rod 11, the second rod 12 and the inner threaded cylinder 13 are connected to the upper and lower rods 12, and the inner threaded cylinder 13 is provided with a reverse thread, at a rod 11 The lower end thread is connected to the upper end of the inner threaded cylinder, the upper end of the second rod 12 is threaded to the lower end of the internal threaded cylinder. When the inner thread barrel 13 is rotated, the spacing of the No. 1 rod 11 and the second rod 12 can be changed, thereby adjusting the length of the vertical boom 1, convenient and flexible.

Abstract

According to the device for rapidly fixing the prestressed corrugated pipe and the operation method, a traditional corrugated pipe fixing mode can be replaced, installation is carried out by fully combining the actual situation of a construction site, the stability of the corrugated pipe in a concrete structure is greatly improved, corrugated pipe fixing and beam side formwork reinforcing synchronous construction is achieved, the construction efficiency is improved, the lifting device comprises a plurality of lifting rod assemblies, the lifting rod assemblies are distributed in the length direction of a prestressed beam in a suspended mode, and the lower end of each lifting rod assembly lifts the pipe wall of a prestressed corrugated pipe; and the plurality of suspender assemblies are used for jointly hoisting the prestressed corrugated pipe and enabling the prestressed corrugated pipe to be distributed in a concave curve shape.

Description

Technical field [0001] The present invention relates to the field of prestressed bellows mounting of the prestressed beam, and more particularly to a device and an operation method of a rapid fixed prestressed bellows. Background technique [0002] With the rapid development of my country's scientific and technology, the span and scale of civil, public and other buildings are getting bigger and larger, and have a variety of structural forms. The widespread use of prestressed technology improves the spatial and comfort of the building. The prestressed bellows are fixedly mounted in the length of the frame beam, and then the concrete is poured. After the concrete reaches the intensity, it is prestressed to form a prestressed beam. However, the traditional prestressed bellows fixing method is welded positioning steel, which is complex, which is not conducive to post adjustment, and cannot be synchronized with other steps, and the construction efficiency is low. Inventive content ...
