Abstract
A prefabricated steel structure protective shed frame for a railway business line. The concrete foundation comprises a concrete foundation, embedded bolts, upright posts, cross beams, tie bars and a roof panel; the utility model discloses the advantage: the beam is made of H-shaped steel, so that the quality is ensured, and the cost of raw materials is reduced; the dead weight of the whole structure is reduced, the pressure of the upright post is reduced, and the strength of the whole structure is improved. The nodes are all designed to be connected through bolts without welding. Need not to use equipment such as electric welding in the installation, reduced the construction process, improved the work efficiency of construction in the skylight point, avoided safety risks such as high altitude welding, electric shock simultaneously. When in installation, the components can be assembled on the ground according to different parts and then integrally hoisted; the assembling process can be carried out outside the skylight points, so that the construction processes in the skylight points are reduced, and the working efficiency is improved. If later stage turnover, only need to demolish the bolt and can realize whole turnover, turnover efficiency, high quality avoid causing the unnecessary extravagant because of welding, the partial structure damage that the cutting caused.
Description
Technical Field
The utility model belongs to the technical field of railway construction protector, especially, relate to a railway business line is with prefabricated assembled steel construction protection rack.
Background
In the construction process of crossing six arches on a railway business line or crossing other railway bridges, due to uncontrollable construction process, materials, tools and waste materials often fall on the business line, so that accidents occur in railway driving, and therefore in the construction process of crossing railway bridge engineering, a railway protection shed frame needs to be installed between the business line and a construction main structure to protect the business line from being influenced by external construction conditions; the raw and other materials that traditional protection rack used are comparatively heavy, lead to the loaded down with trivial details, the engineering volume is great, construction period is long, inefficiency, can't effectively have enough to meet the need the use scheduling problem to appear the process in the installation.
Disclosure of Invention
In order to solve the problem, the utility model aims to provide a railway business line is with prefabricated assembled steel construction protection rack.
In order to achieve the purpose, the prefabricated steel structure protective shed frame for the railway business line comprises a concrete foundation, pre-buried bolts, stand columns, cross beams, tie bars and a roof panel; the concrete foundations are in a long-strip plate shape, and the two concrete foundations are arranged on roadbeds on two sides of a business line below the construction main body structure side by side; the lower parts of the embedded bolts are embedded in the concrete foundation, and a plurality of groups of embedded bolts are arranged on the concrete foundation at intervals along the length direction of the concrete foundation; the lower end of each upright post is connected to a concrete foundation by a group of embedded bolts and nuts; two ends of each cross beam are respectively connected with the upper ends of two corresponding upright posts; two ends of the tie bars are connected to two adjacent cross beams at intervals; the roof panel is laid on the outer sides of the cross beams and the tie bars and is fixed by nuts.
The prefabricated steel structure protective shed frame for the railway business line further comprises a cross brace connected between every two adjacent stand columns.
Each group of embedded bolts consists of 6 embedded bolts distributed in a shape like a Chinese character 'ri'.
The cross beam is made of H-shaped steel.
The utility model provides a railway business line is with prefabricated assembled steel construction protection rack has following advantage:
1. the beam is made of H-shaped steel, so that the quality is ensured, and the cost of raw materials is reduced; meanwhile, the dead weight of the whole structure is reduced, the pressure of the stand column is reduced, and the strength of the whole structure is improved.
2. The nodes are all designed to be connected through bolts without welding. Need not to use equipment such as electric welding in the installation, reduced the construction process, improved the work efficiency of construction in the skylight point, avoided safety risks such as high altitude welding, electric shock simultaneously.
4. When in installation, the components can be assembled on the ground according to different parts and then integrally hoisted; the assembling process can be carried out outside the skylight points, so that the construction processes in the skylight points are reduced, and the working efficiency is improved. If later stage turnover, only need to demolish the bolt and can realize whole turnover, turnover efficiency, high quality avoid causing the unnecessary extravagant because of welding, the partial structure damage that the cutting caused.
5. Through the inspection and calculation of professional departments, the structural design completely meets the construction protection requirements of the railway business line.
