Description

Technical Field

[0001] The present invention belongs to the technical field of steel structure engineering, and particularly relates to an installation structure and an installation method for a steel structure corridor. Background Art

[0002] In mines, steel mills, and cement plants, belt conveyors are usually used to transport various raw materials such as iron ore, coke, and pulverized coal to production units or transfer stations. The belt conveyor transportation system is generally placed in a closed steel structure corridor, which can reduce the overflow and dust of transported materials and meet the increasingly strict environmental protection requirements.

[0003] The streamline of the belt conveyor transportation system is complex and variable, resulting in many changes in the span and elevation angle of the steel structure corridor, making it difficult to standardize the design, manufacture, and installation, and the degree of productization is low.

[0004] The steel structure corridor forms a stable space structure by vertical trusses and horizontal members and is placed on the support crossbeam. The vertical trusses bear the material load, maintenance load, roof snow load, etc. of the belt conveyor transportation system. Usually, the end columns of the vertical trusses are perpendicular to the horizontal plane, and a slight change in the elevation angle will cause a change in the inclined length of the steel structure corridor. The trusses composed of horizontal members mainly bear the wind load.

[0005] The support spacing is usually 20 meters to 50 meters. When changing the elevation angle of the steel structure corridor, the inclined length of the steel structure corridor changes, and then the joint dimensions of the vertical trusses and horizontal members change. Therefore, for the same support spacing, if the elevation angles of the steel structure corridors are different, the joint dimensions of the corridors are different, resulting in a large variety of steel structure corridor components and a low degree of standardization.

[0006] The current design method is to first determine the support spacing and then design the steel structure corridor according to the elevation angle. If the elevation angle is slightly different, the size of the steel structure corridor will be different, making it difficult to standardize and unable to achieve the purpose of mass production of products. Summary of the Invention

[0007] In view of the above-mentioned deficiencies of the prior art, the purpose of the present invention is to provide an installation structure for a steel structure corridor, which is suitable for steel structure corridors with different elevation angles.

[0008] To achieve the above purpose and other related purposes, the technical solution of the present invention is as follows:

[0009] An installation structure for a steel structure corridor includes supports and a space truss installed on the supports. A hinge seat is additionally provided between the end of the space truss and the support and is rotationally connected through the hinge seat, and the elevation angle of the space truss is adjustable.

[0010] An adjustable-angle hinge seat is added between the space truss and the support of the steel structure aisle of the present invention to adapt to different elevation angles. The panel lengths of the steel structure aisles with the same span or length are the same, which improves the standardization degree, enables batch production of the steel structure aisles, improves the project quality, and reduces the project cost.

[0011] Optionally, both ends of each said space truss are respectively installed on two spaced supports through corresponding hinge seats. Among two adjacent space trusses, the tail end of the previous space truss and the head end of the subsequent space truss are respectively rotatably installed on the same support through hinge seats.

[0018] Optionally, a strip-shaped adjustment hole or an enlarged hole is formed in the lower bottom plate. The lower bottom plate is bolted to the support and is laterally adjustable on the support.

[0019] Optionally, a reinforcing plate is provided between the upper bottom plate and the upper vertical plate and / or between the lower bottom plate and the lower vertical plate.

[0020] Optionally, a reinforcing plate is provided between the lower bottom plate and the lower vertical plate. Both ends of the rotating shaft are connected with end plates. Both ends of the rotating shaft are stepped shafts. A central hole is provided on the end plate. The end of the rotating shaft is inserted into the central hole, and the shaft shoulder of the rotating shaft abuts against the inner side of the end plate. The reinforcing plate between the lower bottom plate and the lower vertical plate presses against the outer side of the end plate and is welded and fixed to the end plate.

Specific implementation mode

[0036] The following specific embodiments illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0037] Embodiment

[0038] Figure 1The following shows the installation method of a traditional steel structure corridor and support 1. The steel structure corridor is formed by a vertical truss 2a and a horizontal member 2b to form a stable space structure. The end column member 21 of the vertical truss 2a of the steel structure corridor is perpendicular to the horizontal plane, and a slight change in the elevation angle will cause a change in the diagonal length of the steel structure corridor. When changing the elevation angle α of the steel structure corridor, the diagonal length of the steel structure corridor changes, and then the panel lengths of the vertical truss 2a and the horizontal member 2b ( Figure 3 shown in) change. Therefore, for the same support 1 spacing, if the elevation angles α of the steel structure corridors are different, the panel lengths of the corridors are different, resulting in a large variety of steel structure corridor components and low standardization.

[0039] As Figures 2 to 5 shown, to adapt to different elevation angles α and improve the standardization and versatility; an installation structure of a steel structure corridor in this example includes a support 1 and a space truss 2 installed on the support 1, where the space truss 2 is the main part of the steel structure corridor, and the space truss 2 is rotationally installed on the support 1 through a hinge seat 3. Specifically, the end of the space truss 2 is rotationally connected to the support 1 through the hinge seat 3, realizing that the elevation angle α of the space truss 2 is adjustable.

[0040] An adjustable-angle hinge seat 3 is added between the space truss 2 of the steel structure corridor and the support 1 to adapt to different elevation angles α. The panel lengths of steel structure corridors with the same span or length are the same, improving the standardization, enabling batch production of steel structure corridors, improving the project quality, and reducing the project cost.

[0041] Of course, the steel structure corridor also includes other accessories besides the space truss 2, such as purlins, wall panels, roof panels, belt conveyor supports, etc.

[0042] Among them, each end of the space truss 2 is supported on the support 1 by at least two hinge seats 3, and the hinge seats 3 are arranged side by side in the width direction of the space truss 2; each hinge seat 3 includes an upper support 31 and a lower support 32 connected by a rotating shaft 34, the upper support 31 is connected to the space truss 2, and the lower support 32 is installed on the support 1; specifically, the space truss 2 includes a vertical truss 2a and a horizontal member 2b, the vertical truss 2a includes a lower chord member 22 and a column member 21, where the end column member 21 of the vertical truss 2a is perpendicular to the lower chord member 22, the upper support 31 is fixed on the lower chord member 22, and the lower support 32 is installed on the cross beam or platform at the upper end of the support 1.

[0043] The end column member 21 of the space truss 2 is not perpendicular to the ground but perpendicular to the lower chord member 22 of the space truss 2. When the elevation angle α changes, the end column member 21 remains perpendicular to the lower chord member 22, which can achieve the purpose of batch production of products, directly select standard steel structure corridor products, and improve the design efficiency.

[0044] AsFigure 6 and Figure 7 As shown in Figure 7 , in this example, the upper support 31 includes an upper bottom plate 311 and an upper vertical plate 312 connected below the upper bottom plate 311. The upper bottom plate 311 is welded and fixed to the lower chord member 22, specifically to the lower surface of the lower chord member 22. The lower support 32 includes a connected lower bottom plate 321 and a lower vertical plate 322. The lower bottom plate 321 is welded or bolted 36 to the support 1. Corresponding shaft holes for installing the rotating shaft 34 are provided on the upper vertical plate 312 and the lower vertical plate 322, and they are rotatably connected through the rotating shaft 34.

[0045] As Figure 8 shown in Figure 8 , the installation schematic diagram of the hinge seats 3 corresponding to two adjacent space trusses 2 on the same support; Figure 8 In Figure 8 , after the hinge seat 3 on the left side (the hinge seat 3 at the right end of one space truss 2) is bolted to the support 1 and then welded, the lateral position is fixed. Specifically, connection holes 324 are provided on the bottom plate 321 of the hinge seat 3 on the left side. After the bolts pass through the connection holes 324 and are connected to the support 1, the lower bottom plate 321 is welded to the support 1. The position of the hinge seat 3 on the right side (the hinge seat 3 at the left end of the other space truss 2) is adjustable in the span direction with respect to the support 1. Specifically, adjustment holes 323 are provided on the lower bottom plate 321, and the lower bottom plate 321 is connected to the support 1 through bolts 36. The bolts 36 pass through the adjustment holes 323 and are connected to the support 1, so that the lateral position of the lower bottom plate 321 on the support 1 is adjustable. A spacer 37 is also provided between the bolts 36 and the lower bottom plate 322. To adjust the lateral position of the space truss 2 on the support 1, the adjustment holes 323 can be strip-shaped holes or enlarged holes with a size larger than the bolts 36.

[0046] To improve the strength of the upper support 31 and the lower support 32, a plurality of reinforcing plates 33 are provided between the upper bottom plate 311 and the upper vertical plate 312, and / or a plurality of reinforcing plates 33 are provided between the lower bottom plate 321 and the lower vertical plate 322. The reinforcing plates 33 are fixed to the upper support 31 and the lower support 32 by welding.

[0047] In this example, the limiting structure is an end plate 35, and the end plate 35 is connected to both ends of the rotating shaft 34. Specifically, both ends of the rotating shaft 34 are stepped shafts. Central holes are provided on the end plate 35, and the ends of the rotating shaft 34 are inserted into the central holes. The shoulders at both ends of the rotating shaft 34 abut against the inner side of the end plate 35. The reinforcing plate 33 between the lower bottom plate 321 and the lower vertical plate 322 presses against the outer side of the end plate 35 and is welded and fixed to the end plate 35 to provide lateral support.

[0048] In one embodiment, the lower supports 32 of each hinge seat 3 are in two groups, and the upper vertical plate 312 of the upper support 31 is located between the two lower vertical plates 322 of the two groups of lower supports 32. The rotating shaft 34 passes through the upper vertical plate 312 and the two lower vertical plates 322, and a limiting structure for restricting the axial movement of the rotating shaft 34 is provided on the lower vertical plate 322. Alternatively, each lower support 32 includes a lower bottom plate 321 and two lower vertical plates 322 which are installed on the lower bottom plate 321 and spaced apart, and the upper vertical plate 312 of the upper support 31 is located between the two lower vertical plates 322.

[0049] Both ends of each space truss 2 are respectively installed on two brackets 1 arranged at intervals through corresponding hinge seats 3.

[0050] The installation method of two adjacent space trusses 2 on the same bracket 1 is as follows: the tail end of the previous space truss 2 is installed on the bracket 1 through at least two juxtaposed hinge seats 3, and the head end of the subsequent space truss 2 is rotatably installed on this bracket 1 through at least two other hinge seats 3, and their positions are referenced to the positioning line of the bracket 1.

[0051] When the steel structure corridor has an elevation angle α, the rotation center heights of the hinge seats 3 of the two space trusses 2 installed on the same bracket 1 are different on this bracket 1. That is, the rotation center of the hinge seat 3 at the tail end of the previous space truss 2 is different from the rotation center of the hinge seat 3 at the head end of the subsequent space truss 2; as Figure 3 shown, the height of the rotation center of the left hinge seat 3 is higher than that of the right hinge seat 3. During manufacturing, the upper support 31 can be designed with a general size, and the lower support 32 can be designed with different height dimensions to adapt to different elevation angles α.

[0052] Among the two space trusses 2 installed on the same bracket 1, the position of the hinge seat 3 of one space truss 2 is fixed on the bracket 1, and the lateral position (span direction) of the hinge seat 3 of the other space truss 2 on the bracket 1 is adjustable, that is, an adjustment hole 323 is provided on the lower support 32 to adjust the lateral position, as Figure 3 and Figure 8 shown, the position on the left is fixed, and the position on the right is adjustable.

[0053] As Figure 5 shown, both ends of each space truss 2 are respectively installed on two brackets 1 arranged at intervals through corresponding hinge seats 3. The leftmost one in the figure is the first bracket 1a, and the rightmost one is the second bracket 1b; the lateral position of the hinge seat 3 at the left end of this space truss 2 is fixed on the first bracket 1a, and the position of the hinge seat 3 at the right end on the second bracket 1b in the span direction of the space truss 2 is adjustable to adapt to the spacing error between the first bracket 1a and the second bracket 1b, etc. Of course, in other embodiments, it can also be that the right end is fixed and the left end is adjustable.

[0054] Specifically corresponding toFigure 5 In it, another space truss 2 installed on the first support 1a, and the position of its corresponding hinge support 3 on the first support 1a is adjustable, and is adjusted along the span direction of the space truss 2; while installed on Figure 5 Another space truss 2 on the second support 1b in it, and the position of its corresponding hinge support 3 on the second support 1b is fixed; that is, among the two space trusses 2 installed on the same support 1, the position of the hinge support 3 of one space truss 2 on the support 1 is fixed, and the lateral position of the hinge support 3 of the other space truss 2 on the support 1 is adjustable.

[0055] Based on the above installation structure, the present invention also provides an installation method for a steel structure aisle:

[0056] 1. Provide the hinge support 3, and prefabricate space trusses 2 with the same or different length dimensions; that is, the length of the space truss 2 is no longer determined according to the spacing of the supports 1;

[0057] 2. Weld the upper support 31 of the hinge support 3 to the lower chord member 22 of the space truss 2, and install the accessory components on the space truss 2 to form a steel structure aisle. The accessory components include purlins, wall panels, roof panels, belt conveyor supports, etc.; these accessory components are existing structures and will not be elaborated;

[0058] 3. During installation, first install a plurality of supports 1 on the foundation; the spacing distance of the supports 1 is determined according to the length dimension of the selected space truss 2;

[0059] 4. Install the space truss 2 (i.e., the steel structure aisle) with the aisle accessory components on the support 1 through the hinge support 3; specifically, hoist the steel structure aisle above the support 1, connect the hinge support 3 at one end of the space truss 2 to the first support 1a by bolts, and then weld and fix it; connect the hinge support 3 at the other end of the space truss 2 to the second support 1b. Specifically, first pass the bolt 36 through the adjustment hole 323 of the lower support 32 to connect with the support 1, adjust the position in the span direction and position it, and then weld the lower support 32 to the support 1; of course, it is also possible to weld after both ends are connected by bolts 36; or just connect by bolts 36 without welding.

[0060] Among them, the hinge support 3 has been connected to the space truss 2 in the second step. In order to further improve the standardization production level of the steel structure aisle, the welding of the upper support 31 and the lower chord member 22 of the space truss 2 is completed in the factory. The lower support 32 can adopt different external dimensions and is applicable to steel structure aisles with different elevation angles α and spans.

[0061] The beneficial effects of the present invention are:

[0062] 1. An adjustable-angle hinge seat 3 is added between the space truss 2 of the steel structure aisle of the present invention and the bracket 1 to adapt to different elevation angles α. The panel lengths of the steel structure aisles with the same span or length are the same, which improves the standardization degree, enables batch production of the steel structure aisles, improves the project quality, and reduces the project cost.

[0063] 2. The end column member 21 of the space truss 2 is not perpendicular to the ground but perpendicular to the lower chord member 22 of the space truss 2. When the elevation angle α changes, the end column member 21 remains perpendicular to the lower chord member 22, which can achieve the purpose of batch production of products. Standard steel structure aisle products can be directly selected, improving the design efficiency.

[0064] 3. The bracket 1, the steel structure aisle, and the hinge seat 3 are all fabricated in the factory and hoisted on site, with high connection efficiency and fast installation speed.

[0065] The present invention changes the prior art method of first determining the bracket spacing and then designing the aisle steel structure according to the elevation angle. It overcomes the problem that due to different elevation angles, the sizes of the steel structure aisles are different, making it difficult to standardize and impossible to achieve mass production of products. The present invention can achieve the standardization and batch production of the steel structure aisle, is not dependent on the bracket spacing and elevation angle, and improves the operation efficiency.

[0066] Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
