Description

Technical Field

[0001] The utility model relates to the technical field of coal sheds, in particular to a coal shed with good tensile performance. Background Art

[0002] A coal shed is a building or facility used to store coal, usually for industrial, commercial or residential purposes. The design of a coal shed requires consideration of a variety of factors, including storage requirements, safety, environmental considerations, and the natural forces that may affect the structure.

[0003] Compared with traditional house-structure coal storage methods, large-span steel grid coal storage sheds have many advantages, including light weight, large span, short construction period, economical and energy-saving, and reusable. However, in daily use, coal sheds are affected by wind, especially large-span steel grid structures, which may be subject to large lateral loads. This is mainly manifested in the lateral impact of wind, which causes the structure to be stretched in the lateral direction.

[0004] Since the large-span steel grid structure has the characteristics of light weight and high freedom, it is relatively flexible. When it is subjected to lateral impact of strong wind, the structure may experience horizontal stress. This is mainly due to the lateral load imposed by the wind on the structure. At the same time, considering the expansion and contraction of the structure caused by temperature changes, this further increases the complexity of the lateral tensile effect on the structure. Therefore, a coal shed with good tensile performance is proposed. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 An embodiment of the utility model provides a coal shed with good tensile strength, comprising: a middle column 10 and a plurality of side columns 11, the middle column 10 is located in the middle of the plurality of side columns 11, a roof frame 12 is installed on the top of the middle column 10 and the plurality of side columns 11, the roof frame 12 comprises a lower chord 121 and an upper chord 122 of the roof truss, four grooves are symmetrically provided at the top and bottom of the middle column 10, a plurality of single-piece chord supports 13 of the roof truss are installed between the lower chord 121 and the upper chord 122 of the roof truss, wherein two single-piece chord supports 13 of the roof truss are symmetrically installed on both sides of the middle column 10, a damper 14 is installed on the side of the single-piece chord support 13 of the roof truss away from the middle column 10, and one end of the damper 14 is fixedly connected to the roof frame 12.

[0022] According to the above technical solution, the single-piece chord support 13 of the roof truss can resist and disperse the tensile stress when subjected to lateral loads such as external wind force, thereby reducing the impact on the overall structure.

[0023] The symmetrical arrangement of the single-piece chord support 13 on the central column 10 helps to enhance the stability of the overall structure. When facing lateral impact of wind, the single-piece chord support 13 on the roof truss provides additional support and stability by being symmetrically arranged on both sides of the structure, thereby preventing the roof frame 12 from lateral tilting or twisting, and solving the problem of lateral tensile stress of the structure that is prone to occur under the action of wind.

[0024] The damper 14 is installed between the two sides of the central column 10 and the single-piece chord support 13 of the roof truss, which can reduce the vibration of the structure, thereby improving the seismic performance of the coal shed. When subjected to external wind lateral loads, reducing vibration helps maintain the stability of the structure and prevent structural fatigue and damage.

[0025] This enables the coal shed to maintain higher stability and tolerance under conditions of large span and wind.

[0026] In one embodiment of the present invention, Figure 3 As shown, the lower chord 121 of the roof truss includes a plurality of rods 1211 and a plurality of bolt balls 1212, and the plurality of rods 1211 and the plurality of bolt balls 1212 are installed with each other to form a quadrangular pyramid.

[0027] According to the above technical solution, through such an arrangement, the structural strength and stability of the lower chord 121 of the roof truss are enhanced to form a solid and reliable support system suitable for large-span structures. Especially when facing lateral loads such as wind, the external load acts on the bolt ball 1212, so that the rod 1211 is subjected to axial force, tension or compression to fully utilize the strength of the rod 1211, thereby effectively dispersing and bearing external loads and improving the resistance and tolerance of the overall structure.

[0028] In one embodiment of the present invention, Figure 3 and Figure 4 As shown, a rubber sleeve 1213 is installed on the outside of the rod 1211. Through such a configuration, the heat conduction between the rod 1211 and the external environment is reduced, which helps to maintain the stability of the rod 1211.

[0029] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the upper chord 122 of the roof truss includes a plurality of grids 1221, which are installed on the top of the lower chord 121 of the roof truss, and a top plate 1222 is installed on the top of the grids 1221. Through such an arrangement, the plurality of grids 1221 form a uniformly distributed support system, which effectively improves the stability of the overall structure, can resist the influence of lateral loads such as external wind force, and enhances the stability and durability of the entire coal shed structure.

[0030] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, a plurality of C-shaped steels 1223 are installed between the grid 1221 and the top plate 1222. Through such an arrangement, the distribution of the C-shaped steels 1223 forms a plurality of fulcrums, which can more evenly disperse the load from the grid 1221, reduce the point pressure on the top plate 1222, and improve the bearing capacity of the grid 1221 for external loads.

[0031] In one embodiment of the utility model, specifically, the outside of the rod 1211 is coated with a ceramic coating. Through such a setting, the ceramic coating has excellent corrosion resistance, can effectively prevent the external environment (such as humidity, acid rain, etc.) from corroding the frame 1221, and extend the service life of the rod 1211.

[0032] In one embodiment of the utility model, specifically, the lower chord 121 and the upper chord 122 of the roof truss are both alloy steel. Through such a setting, the lower chord 121 and the upper chord 122 of the roof truss of the coal shed can have high strength, light weight, wind resistance, corrosion resistance and other properties, thereby improving the structural stability and durability of the entire coal shed.

[0033] This enables the coal shed to maintain higher stability and tolerance under conditions of large span and wind.

[0034] Parts not involved in the present invention are the same as the prior art or can be implemented by the prior art. Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the attached claims and their equivalents.
