Description
Technical Field
The utility model relates to a gantry crane track roof beam, more specifically the assembled gantry crane track roof beam that says so belongs to subway station gantry crane track roof beam design technical field.
Background
With the development of economic society of China and the acceleration of urbanization process, more and more permanent population is flooded into limited urban space. In order to solve the contradiction between the increase of urban population and the shortage of land, more and more cities start the construction of urban rail transit, and a gantry crane is generally used for horizontal transportation and vertical transportation of substances in the construction process of subway stations and shield intervals; particularly, in the area of a shield starting well, a gantry crane is needed to hoist shield segments and other substances needed in the shield tunneling process.
In general, in order to smoothly hoist the shield machine in the shield starting well of the subway station, the width of the shield starting well area is larger than that of other areas of the subway station; and because the construction site of the subway station is generally in the urban area, the site space is limited, and in order to reduce the occupation of the gantry crane on the ground space of the construction site of the subway station, the gantry crane track foundation of the shield starting well area is arranged on the crown beam at the end part of the shield starting well. The surface elevation of the portal crane rail base in the general area of the subway station is slightly higher than the ground elevation, the surface elevation of the crown beam at the end part of the starting well is dozens of centimeters lower than the ground elevation, and in order to keep the surface elevation of the portal crane rail base in all areas at the same elevation, the crown beam in the shield starting well area needs to be raised by dozens of centimeters. At present, concrete is generally poured on the crown beam, so that the surface elevation of the poured concrete is consistent with the surface elevation of the gantry crane track foundation. However, this approach has the following disadvantages: 1. concrete is poured, a support and a template need to be erected before pouring, and the construction process is multiple; 2. the concrete foundation has long maintenance time, high cost, one-time investment and non-recycling use; 3. after the concrete gantry crane foundation is constructed in the subway station and the shield interval, the part of the concrete foundation higher than the backfill design elevation needs to be chiseled to the backfill elevation, time and labor are wasted, and the efficiency is low.
Disclosure of Invention
The utility model aims to solve the problems that the construction process is more, the cost is high, the efficiency is lower and the like in the existing mode that adopts the concrete to pour on the crown beam to make the concrete surface elevation and the portal crane track basic surface elevation be consistent, and provide an assembly type portal crane track beam.
In order to achieve the above object, the technical solution of the present invention is: the utility model provides an assembled portal crane track roof beam, includes a plurality of rectangular shape H shaped steel 1 of arranging in proper order, is connected between the adjacent H shaped steel.
A plurality of inner plates are arranged on the strip-shaped H-shaped steel, bolt holes are formed in two sides of the bottom of the H-shaped steel, high-strength bolts and high-strength nuts are connected between the adjacent H-shaped steel through the bolt holes in the inner plates, and the H-shaped steel is connected with the crown beam through the bolt holes in the bottom.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the H-shaped steel component in the utility model has smaller size, lighter weight, convenient transportation and installation, and can be quickly installed on site, and the gantry crane can be quickly installed and put into use; and all adopt high-strength steel in the H shaped steel, the structural deformation is little, rigidity and stability are good, have guaranteed that the live time is long.
2. The utility model discloses well H shaped steel can be at mill's preprocessing, can guarantee the size precision of component, avoids appearing because the problem that the installation of size error is not last.
3. The utility model discloses in except that the earth anchor bolt, other components can recycle, have practiced thrift a large amount of materials, economical and practical.

FIG. 2 is a schematic view of the structure of the H-shaped steel of the present invention.
Fig. 3 is a cross-sectional view of the H-section steel of the present invention.
Fig. 4 is an installation schematic diagram of the present invention.
In the figure, H-shaped steel 1, an inner plate 2, bolt holes 3, high-strength bolts 4, high-strength nuts 5, crown beams 6, ground anchor bolts 7 and rails 8.
Detailed Description
The invention is described in further detail below with reference to the following description of the drawings and the detailed description.
Referring to fig. 1 to 4, an assembled gantry crane track beam is an improved conventional construction method of a gantry crane track beam in a shield starting well region, belongs to an assembled and recyclable steel structure gantry crane track beam, and is suitable for construction of a shield starting well gantry crane track beam in subway tunnel engineering; the H-shaped steel comprises a plurality of strip-shaped H-shaped steels 1 which are sequentially arranged, and adjacent H-shaped steels 1 are connected. A plurality of strip-shaped H-shaped steels 1 are connected together to form a longer gantry crane track beam; divide into a plurality of H shaped steel 1 with portal crane track two, made things convenient for transportation, installation, dismantlement.
Referring to fig. 1 to 4, a plurality of inner plates 2 are arranged on the strip-shaped H-shaped steel 1, and bolt holes 3 are arranged on two sides of the bottom of the H-shaped steel 1; the adjacent H-shaped steel 1 are connected through bolt holes 3 in the inner plate 2 by high-strength bolts 4 and high-strength nuts 5, and the H-shaped steel 1 is connected with the crown beam 6 through anchor bolts 7 and high-strength nuts 5 through bottom bolt holes 3. The structure provides a stressed carrier for a gantry crane track, and transmits the force borne by the H-shaped steel 1 to the concrete crown beam 6; and the transportation, the installation and the disassembly are convenient, the stability of the single H-shaped steel 1 is enhanced, and the strength, the rigidity and the stability between the adjacent H-shaped steels 1 are enhanced.
Referring to fig. 1 to 4, the gantry crane track beam has a simple structure, is convenient to mount, dismount and use, and can be dismounted and recycled; and the gantry crane has reasonable strength and strong size adaptability, can be quickly installed on site, and is greatly favorable for the gantry crane to be quickly put into use in the working range of the gantry crane. Before the gantry crane track beam is installed, a gantry crane track beam installation area is poured by concrete, the ground of the installation area is leveled, and meanwhile, the ground anchor bolts 7 are pre-embedded. During installation, the H-shaped steel 1 is connected through the anchor bolts 7, the high-strength nuts 5 and the bolt holes 3, and the adjacent H-shaped steel 1 is connected through the high-strength bolts 4, the high-strength nuts 5 and the bolt holes 3. By analogy, appropriate H-shaped steel 1 is selected according to the length, the installation number and the length of the installation area of the gantry crane track beam, and after all H-shaped steel 1 are installed, the gantry crane track 8 can be installed on the upper surface of the H-shaped steel 1.
The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described.
