Problems solved by technology

[0005] 1. The transportation of the pipe gallery segment has high requirements on the site of the construction site. It must meet the entry and exit of transport vehicles and the work of the hoisting machine, and at the same time meet the movement of the hoisting machine. Therefore, the hoisting of the pipe gallery is limited and flexible. Low, poor construction accuracy
[0006] 2. Adopt traditional hoisting equipment, most of which are cantilever hoisting, and have strict requirements for hoisting weight
[0007] 3. In the prior art, in order to meet the above requirements, it is usually necessary to invest a lot of manpower and material resources in the pretreatment before construction, resulting in unnecessary cost investment and prolonging the construction period

Embodiment 1

[0051] Such as Figure 1-5 As shown, a hoisting device for prefabricated segments is provided in this embodiment, which mainly includes a support column 1, a beam 2 arranged on the support column 1, a longitudinal beam 3 arranged on the beam 2, and a longitudinal beam arranged on the longitudinal beam 2. The hoisting mechanism 4 on the beam 3.

[0052] One end of the supporting column 1 is provided with a bent portion 11 , and the supporting device 5 is disposed on the bent portion 11 . The other end of the support column 1 is slidably connected to the beam 2 . As a preferred solution, the support device 5 includes a support part 51, a height-adjustable column 52 arranged on the support part 51, and a height-adjustable column 52 provided on the column 52 for adjusting the height of the bending part 11. Adjusting device; the support part 51 is provided with a rotating wheel 511 . Further, the upright 52 includes a first upright and a second upright that are nested in each ot...

Embodiment 2

[0060] The same as in Embodiment 1 will not be repeated, such as Image 6 As shown, in this embodiment, the bending parts 11 are arranged on the ground on both sides of the prefabricated segment 6 in opposite directions. Moreover, an arc-shaped contact structure is provided between the support portion 51 and the column 52, the arc-shaped contact includes an arc-shaped concave surface 522 provided on the support portion 51, and an arc-shaped concave surface 522 is provided on the column 52 corresponding to the arc-shaped concave surface 522. The arc-shaped protrusion 521 at the end is fixedly installed between the support column 1 and the fixed surface through the contact between the arc-shaped protrusion 521 and the arc-shaped concave surface 522, and can be applied to uneven ground.

Embodiment 3

[0062] In order to facilitate the understanding of the scheme, based on the hoisting device described in Example 1, such as Figure 7-9 As shown, a hoisting method is provided in this embodiment:

[0063] Firstly, segmental design is carried out on the embedded parts, and the members with regular cross-section are divided according to a certain length, and the division principle meets the transportation conditions. That is to say, within the effective length, the segment can withstand the load generated by the segment and the racking equipment. The second is to prefabricate the sections, using factory prefabrication to process the underground section box structure, and the required components are produced and processed by the prefabrication factory to ensure quality and reduce environmental pollution during production. Then the foundation pit 7 is excavated. The foundation pit 7 can be excavated in the form of grading excavation or steel sheet piles, and the segment length ca...

Abstract

The invention discloses a hoisting device for prefabricated segments. The hoisting device comprises support columns, a cross beam arranged on the support columns, longitudinal beams arranged on the cross beam and hoisting mechanisms arranged on the longitudinal beams, wherein a bending part is arranged at one end of each of the support columns; supporting devices are arranged on the bending parts;the other end of each of the support columns is connected with the cross beam in a sliding manner; the two ends of the cross beam are connected with the support columns in a sliding manner; the longitudinal beams are connected with the lower part of the middle part of the cross beam in a sliding manner; and the hoisting mechanisms are connected with the longitudinal beams in a sliding manner. A hoisting machine in the prior art is not needed to be used, hoisting mounting of the prefabricated segments can be conveniently realized, a requirement on quick and high-efficient repeated use can be met, and popularization and application are convenient.

Description

technical field [0001] The invention belongs to the technical field of civil construction, and in particular relates to a hoisting device for a prefabricated segment and a hoisting method thereof. Background technique [0002] At present, the erection of prefabricated structures has been gradually carried out at home and abroad. As an emerging construction project in the past two years, underground comprehensive pipe corridors, current urban underground road construction projects, and large subway projects are all lacking in the construction of prefabricated structures. Prefabricated structure, as a structural engineering with low environmental impact and high construction quality, is the only way for future development. [0003] The underground structure can be roughly divided into open-cut structure and underground structure. Due to the control of the use function and cost, the construction of underground structures often adopts the principle of shallow buried depth. The...
