Description

Technical Field

[0001] The utility model relates to the technical field of skid-mounted equipment, and particularly to a modular skid-mounted steel structure with welded rectangular steel columns. Background Technique

[0002] Skid-mounted modular and standardized design is to integrate equipment, pipelines, etc. into skids according to functional units, and make skids similar in size to containers, which can achieve rapid and accurate construction of projects.

[0003] The steel structure is the skeleton of the entire skid structure. The disassembly, transportation, hoisting and normal use of the skid all depend on the steel structure skeleton to proceed normally. The cost of the steel structure accounts for about 5%-15% of the overall skid cost. With the increasingly fierce market competition, the cost issue has always been one of the core factors affecting the competitiveness of skid products.

[0004] Most traditional skid steel structures use H-shaped cross-section steel columns plus H-shaped cross-section steel beams as the load-bearing skeleton (such as a skid with a simple structure disclosed in the patent number CN202321202834.1). Due to the large difference in the load-bearing capacity of the H-shaped steel column in two directions, there are potential safety hazards in its weak axis direction under earthquake action. In order to ensure that the traditional skid steel structure has a certain seismic performance, it is necessary to increase the model or size of the H-shaped steel column according to the maximum load-bearing capacity of the weak axis of the H-shaped steel column. However, there is a large margin in the strong axis load-bearing capacity of the H-shaped steel column, which results in an increase in the steel consumption and an increase in the cost. Content of the Utility Model

[0005] Therefore, to solve the above deficiencies, the utility model provides a modular skid-mounted steel structure with welded rectangular steel columns. This skid-mounted steel structure forms a steel structure through the combination of rectangular columns and H-shaped cross-section beams. The rectangular columns are in contact with the ground. Since the load-bearing capacity of the cross-section of the rectangular columns is roughly the same in two directions, the potential safety hazards under earthquake action are reduced, and the seismic performance of the overall structure is improved. Moreover, the rectangular columns can save about 15% of the steel consumption compared with H-shaped cross-section steel columns with the same load-bearing capacity.

[0006] The utility model is realized as follows: A modular skid-mounted steel structure with welded rectangular steel columns is constructed, including several parallel columns;

[0007] Several cross-beams are respectively connected between several columns to connect them together;

[0008] The cross-section of the column is a rectangular frame, and the cross-section of the cross-beam is H-shaped and the open end direction is kept consistent with the side direction of the column.

[0009] Specifically, the vertical columns are placed vertically and keep their bottom ends in contact with the ground. A plurality of the cross beams are arranged in layers at different heights of the columns. Each layer of cross beams encloses between a plurality of columns to form a closed shape. Two end portions of each cross beam are respectively connected to the side surfaces of the columns in a fixed manner.

[0010] Specifically, the fixing manner of the cross beam and the column is welding.

[0011] Specifically, a plurality of groups of mounting holes are uniformly formed in the side surface of the column along the length direction. Each group of mounting holes penetrates through two adjacent side surfaces of the column and keeps the same height. There are two mounting holes in each group on any one side surface. A support rod can be inserted into each group of mounting holes on any one side surface. The end portion of the support rod extends outside the mounting hole, and the end portion of the cross beam can be inserted into the support rod to keep support and fixation.

[0012] Specifically, the cross-sectional shape of the column is a square frame.

[0013] Specifically, both the column and the cross beam are made of steel.

[0014] The utility model has the following beneficial effects:

[0015] 1. The skid-mounted steel structure adopts welded rectangular-section steel columns. The load-bearing capacities in two directions of the rectangular section are the same, so it has high seismic performance, making the entire skid structure safer. And compared with H-shaped-section steel columns with the same load-bearing capacity, the steel columns with rectangular sections have smaller self-weights, are faster to lift as a whole, are convenient for transportation, have a light and beautiful appearance, and are economical and reasonable.

[0016] 2. The skid-mounted steel structure is equidistantly provided with mounting holes of the same height on the peripheral side surfaces of the rectangular-section steel columns. Combining with the support rods that can be inserted into the mounting holes, it is convenient to ensure that the height of each group of cross beams is the same when welding the cross beams, so as to facilitate the horizontal support of components.

[0024] The technical solution of the present utility model will be further specifically described below through specific embodiments in conjunction with the drawings; it should be understood that the specific embodiments described herein are only used to illustrate and explain the present utility model and do not serve as any limitation to the present utility model; the drawings in the present utility model are only used in conjunction with the embodiments for narration and are convenient for understanding and use, and do not serve as any relevant limitation to the present utility model.

[0025] It should be noted that the structures, ratios, sizes, etc. schematically shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those skilled in this technology to understand and read, and are not used to limit the implementable conditions of the present utility model. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects that the present utility model can produce and the purposes that can be achieved, should still fall within the scope that can be covered by the technical content disclosed in the present utility model.

[0026] As described in the background technology, most traditional skid-mounted steel structures adopt H-shaped cross-section steel columns plus H-shaped cross-section steel beam load-bearing skeletons. Since there is a large difference in the load-bearing capacity of H-shaped steel columns in two directions, there are potential safety hazards in the weak axis direction under earthquake action. If the size or model of the H-shaped steel column is increased, the load-bearing capacity in the strong axis direction of the H-shaped steel column will have a large surplus, undoubtedly resulting in an increase in the amount of steel used and an increase in cost.

[0027] For the above reasons, please refer to the attached Figure 1 - attached Figure 4 , the present utility model provides a welded rectangular steel column modular skid-mounted steel structure, including several parallel columns;

[0028] Several cross beams 2, respectively connected between several columns 1 to connect them together;

[0029] The cross section of the column 1 is a rectangular frame, and the cross section of the cross beam 2 is H-shaped and keeps the opening end direction consistent with the side direction of the column 1.

[0030] Please refer carefully to the attached Figure 1 and the attached Figure 4, after the cross beam is connected to the column, the open end of the H-shaped cross section of the cross beam is aligned with the side surface of the column, so as to ensure that when the column is placed vertically, the strong axis direction of the H-shaped cross beam corresponds to the supporting surface, and thus a larger supporting force can be provided.

[0031] Please continue to refer to the appendix Figure 1 , specifically, the column 1 is placed vertically with its bottom end in contact with the ground, and a plurality of the cross beams 2 are arranged in layers at different heights of the column 1. Each layer of the cross beams 2 encloses between a plurality of columns 1 to form a closed shape, and the two ends of each cross beam 2 are respectively connected to the side surface of the column 1 in a fixed manner.

[0032] According to the above paragraph, arranging the cross beams in layers at different heights of the column can facilitate the formation of supporting surfaces at different heights, so as to facilitate the placement of different components in layers. At the same time, each layer of cross beams encloses between the columns to form a closed shape to facilitate the placement of an external support plate, and a support beam can be installed between each layer of cross beams to place an external support plate, so as to support and fix the components.

[0033] Specifically, the fixing method of the cross beam 2 and the column 1 is welding.

[0034] According to the above paragraph, setting the welding method is to ensure the stability of the cross beam and the column, prevent falling off and displacement, etc., and avoid damage to the components.

[0035] Please refer to the appendix carefully Figure 4 and the appendix Figure 5 , specifically, a plurality of groups of mounting holes 1.1 are evenly formed on the side surface of the column 1 along the length direction. Each group of the mounting holes 1.1 penetrates through the adjacent two side surfaces of the column 1 and has the same height. There are two mounting holes 1.1 in each group on any one side surface. A support rod 3 can be inserted into each group of mounting holes 1.1 on any one side surface. The end of the support rod 3 extends outside the mounting hole 1.1, and the end of the cross beam 2 can be inserted into the support rod 3 to maintain support and fixation.

[0036] According to the above paragraph, the purpose of forming the mounting holes on the side surface of the column is to facilitate the positioning of the cross beam after inserting the support rod, so as to facilitate the welding and fixing of the cross beam. And the mounting holes with the same height are formed on the adjacent side surfaces of the column to ensure that after welding the cross beam, the heights of the cross beams in the same group are the same, so as to facilitate the placement of the support plate in the closed circle enclosed by the cross beams, and the support plate will not tilt or cause one side to be suspended, so that the support plate provides a relatively stable supporting force after being placed horizontally.

[0037] Furthermore, the purpose of the mounting holes is only to position the cross beam after inserting the support rod. Therefore, the aperture of the mounting holes can be set as small as possible, and the support of the end of the cross beam can be realized after the support rod is inserted. Try to avoid too large an aperture affecting the strength of the column.

[0038] Please refer to the appendix Figure 3 , specifically, the cross-sectional shape of the column is a square frame.

[0039] According to the above description, setting the cross-section of the column as a square frame can further ensure that the bearing capacities in two directions of the cross-section are the same.

[0040] , specifically, both the column 1 and the cross beam 2 are made of steel.

[0041] Compared with the H-shaped steel column, the rectangular steel column has stronger seismic resistance, and the principle is as follows:

[0042] Since the H-shaped steel column has a high bearing capacity in the strong axis direction of the cross-section and a small slenderness ratio, generally the cross-section design result of the component is controlled by the weak axis of the H-shaped steel column, and there is a large margin in the bearing capacity and stability in the strong axis direction. By welding a rectangular steel column, the bearing capacities in two directions of its cross-section are approximately equal, and the slenderness ratios in two directions of the cross-section are similar. Since the vibration borne by the steel column during an earthquake may come from different directions, if a large impact force is borne in the weak axis direction of the H-shaped steel column, it is very easy to cause deformation or even fracture. However, the bearing capacities in two directions of the cross-section of the rectangular steel column are approximately equal, so the seismic performance can be effectively improved.

[0043] When installing this skid-mounted steel structure, first fix one end of the column 1 on the ground or plane, and at the same time, the column can be firmly maintained vertically fixed through the reinforcing ribs. Then insert the support rod 3 into a set of installation holes 1.1 at any height of the column 1, and keep the end of the support rod 3 extending outside the column 1 after passing through the installation hole 1.1. Then place the end of the cross beam 2 on the support rod 3 and keep the end in tight contact with the side surface of the column 1. After fixing by welding, remove the support rod 3. Finally, insert the support rod 3 into another installation hole 1.1 of the column 1 on the adjacent side surface of this cross beam 2, put another cross beam 2 and fix it. After repeating the above steps, several columns and several cross beams are fixed, thus forming a steel structure, which is convenient to place a placement board on the cross beam 2 to install components.

[0044] The above description is a detailed description of the preferred and feasible embodiment of the present invention, but the embodiment is not used to limit the patent application scope of the present invention. Any equivalent changes or modified changes completed under the technical spirit disclosed by the present invention shall fall within the patent scope covered by the present invention.
