Walking type pipe gallery formwork supporting device

Abstract

The invention relates to a walking type pipe gallery formwork supporting device. The walking type pipe gallery formwork supporting device comprises a vehicle body, an upper truss, an inner formwork assembly, a cross beam lengthening joint and a length-adjustable inclined strut, wherein the upper truss is connected with the top of the vehicle body; a short section formwork is fixedly connected to the upper portion of the cross beam lengthening joint; a chamfering formwork is arranged at the upper end of an inner side formwork; an upper cross beam of the upper truss is fixedly connected with a top formwork; the two ends of the upper cross beam of the upper truss are connected with the chamfering formwork of the inner side formwork through the cross beam lengthening joint; and one end of the length-adjustable inclined strut is connected with the cross beam lengthening joint. According to the walking type pipe gallery formwork supporting device, the inner side formwork can be adjusted to be fixed to the design position through the length-adjustable inclined strut, and side formworks can be adjusted at multiple angles and in multiple directions; the formwork splicing speed is high, side walls and a top plate can be poured at the same time, the operation efficiency can be greatly improved, the construction period is shortened, and economical efficiency is good; the vehicle body is of a bailey frame structure, the dead load is low, and walking is convenient; and machining and combination can be conducted in a segmented manner in the longitudinal direction, and the walking type pipe gallery formwork supporting device is very flexible to use in an operation section with large longitudinal slope changes.

Description

technical field [0001] The invention relates to the technical field of pipe gallery formwork support devices, in particular to a walking pipe gallery formwork support device. Background technique [0002] In urban municipal road projects, the number of underground comprehensive pipe gallery projects has increased year by year, most of which involve urban pipelines, electric power, water supply and drainage relocation projects. The traditional construction method of the main structure of the underground comprehensive pipe gallery is a full-scale scaffolding or a hydraulic steel formwork trolley. These two traditional methods have certain disadvantages, which are mainly reflected in the following aspects: [0003] First, there are many supporting components of the full hall scaffolding, including horizontal rods, longitudinal rods, sweeping rods, diagonal braces, etc., resulting in a narrow space inside the pipe gallery, and workers cannot normally enter the interior of the p...

AI Technical Summary

Problems solved by technology

[0003] First, there are many supporting components of the full hall scaffolding, including horizontal rods, longitudinal rods, sweeping rods, diagonal braces, etc., resulting in a narrow space inside the pipe gallery, and workers cannot normally enter the interior of the pipe gallery;

[0004] Second, when using full-height scaffolding for construction, the side walls and the roof need to be poured separately, and construction joints need to be set between the side walls and the roof. On the one hand, it increases the cost investment, and on the other hand, it leads to a longer construction period;

[0005] Third, the use of full hall scaffolding construction, when the scaffolding is dismantled, takes up more construction sites, more components, and poor on-site civilized construction; and because the working space of the underground comprehensive pipe gallery is small, the scaffolding and formwork are inconvenient when they are unlucky. Very inefficient;

[0006] Fourth, when a hydraulic steel formwork trolley is used, the cost of the trolley is relatively high, the entire support system is generally heavy, and the structural components are complex. Generally, it is necessary to set up side-to-side support, which occupies a lot of internal space in the pipe gallery and is inconvenient to operate Personnel enter and exit the pipe gallery; and when walking, generally need to use walking rails, the cost is relatively high;

[0007] Fifth, hydraulic steel formwork trolleys are used, which are generally custom-made as a whole, usually for one-time use, and the reuse rate of the trolley is low;

[0008] Sixth, the hydraulic steel formwork trolley is used. Since the trolley is integrally processed and manufactured, it is not suitable for the construction section with a large curve radius, and it is easy to cause mold jamming, and even needs to cut the trolley.
