Description

Technical Field

[0001] The utility model relates to the field of assembled steel structures, in particular to an assembled supporting enclosure structure. Background Art

[0002] Multi-storey industrial plants mostly use reinforced concrete frame structures. These plants have certain dust emissions during production, and there may be other low-risk pollution sources. According to the requirements of national environmental protection policies, these multi-storey reinforced concrete frame structures need to be enclosed to reduce the emission of pollutants during workshop production. At present, the enclosure structure of factory buildings mostly uses metal corrugated steel plates as the main material. A supporting and fixing structure of the corrugated steel plates is set between the corrugated steel plates and the concrete frame structure. The corrugated steel plates are fixed to the purlins of the supporting and fixing structure by self-tapping screws. The supporting and fixing structure is generally composed of vertical wind-resistant columns and multiple purlins in the horizontal direction. The wind-resistant columns of the supporting structure are generally supported on the frame beams, and the purlins are supported on the frame columns and wind-resistant columns respectively. The wind-resistant columns and purlins are connected to the embedded parts on the concrete frame. During the construction process, the rods of the enclosure support structure are generally hoisted to the predetermined position. The on-site workers then weld the wind-resistant columns to the embedded parts on the concrete frame on site, and then hoist the purlins one by one for high-altitude installation. The purlins are connected to the purlin supports on the wind-resistant columns with bolts, and the two ends of the purlins are connected to the embedded purlin supports on the concrete frame with bolts, and finally a corrugated steel plate is formed to support the overall structure.

[0003] But there are several problems:

[0004] 1. The connection has a low fault tolerance. In the existing support structure scheme, the wind-resistant columns and purlins must be connected to the embedded parts on the concrete frame. A large number of embedded parts need to be set on the concrete frame structure. There are many quality control points for the embedded parts, which are difficult to operate. When the position deviation of the embedded parts is large, it will affect the connection between the purlins and the wind-resistant columns. Especially for the purlins, it often causes the purlin support bolt holes to not correspond to the purlin bolt holes. Then the purlins must be welded to the purlin supports on site. A large amount of high-altitude welding on site is not easy to guarantee the construction quality and safety control, and it will damage the galvanized surface paint of the purlins, thus affecting the durability of the purlins.

[0005] 2. Low construction efficiency and difficult to ensure operational safety. ① The installation of loose parts requires many quality and safety control points, making construction control difficult; ② The error of embedded parts in civil engineering often cannot meet the precision requirements of bolt connections in steel structures, resulting in a large amount of high-altitude welding on site, which not only fails to ensure construction quality but also increases construction workload; ③ The on-site loose parts installation has low utilization rates of construction machinery and personnel, resulting in low construction efficiency.

[0006] 3. Adverse effects during production. The existing purlins usually use thin-walled C-shaped steel. The C-shaped purlin has an open cross-section and a large width. It is easy to retain waste or dust during construction and production. After the accumulation during production, the inside of the wall cannot be effectively cleaned, which affects the appearance of the building and easily causes secondary pollution.

[0007] 4. Low space utilization. The purlins have a large extension width, and the entire structure itself occupies a large area. In addition, the purlins of the existing supporting structure are equivalent to being set up and hung on the outside of the concrete frame, which will occupy part of the space outside the concrete structure, resulting in an increase in the area occupied by the entire building. Utility Model Content

[0008] The purpose of this utility model is to provide an assembled support enclosure structure to address the above shortcomings. It adopts an integral assembly technology to reduce the connection nodes with the concrete frame structure, reduce the construction defects caused by the deviation of embedded parts, and reduce the quality control points of the high-altitude installation process, thereby improving the construction efficiency and quality.

[0011] Furthermore, supports are provided at both upper and lower ends of the wind-resistant column; the supports are used to connect the wind-resistant column with embedded parts in the frame beam.

[0012] Furthermore, it also includes a safety net; the safety net is arranged between the two lowest purlins; the safety net is composed of a plurality of mutually perpendicular rods.

[0013] Furthermore, a lifting ear plate is welded at the middle part of the wind-resistant column; the lifting ear plate is used as a temporary lifting point during lifting and installation construction.

[0014] Furthermore, the wind-resistant columns and purlins are made of square steel tubes or rectangular steel tubes.

[0015] Furthermore, the diagonal bracing members are made of thin-walled square steel pipes.

[0016] The beneficial effects of the utility model are:

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the present invention is not limited to the following embodiments.

[0021] Embodiment 1:

[0022] Attached Figure 1, an assembled supporting enclosure structure is arranged between existing concrete frames, and the concrete frame is a rectangular frame structure composed of two parallel frame columns 1 and two parallel frame beams 2; it includes wind-resistant columns 3, purlins 4 and diagonal bracing assemblies 5; a plurality of wind-resistant columns 3 are arranged between the two frame columns 1; a plurality of wind-resistant columns 3 are arranged vertically in the horizontal direction; the two ends of the wind-resistant columns 3 are respectively connected to the two frame beams 2; a plurality of purlins 4 are arranged between adjacent wind-resistant columns 3; a plurality of purlins 4 are arranged horizontally in the vertical direction; the two ends of the purlins 4 are respectively connected to two adjacent wind-resistant columns 3; a diagonal bracing assembly 5 is arranged between the upper and lower adjacent purlins 4. It can be seen from the above structure that the assembled support structure of the utility model is set in the concrete frame, including wind-resistant columns 3, purlins 4 and diagonal bracing components 5. Several wind-resistant columns 3 are arranged in columns between frame columns 1 and are parallel to frame columns 1. The distance between the wind-resistant columns 3 at the head and tail of the wind-resistant column 3 column and the adjacent frame column 1 is 50-100mm. The reason for leaving a gap is to facilitate the installation of the assembled support structure in the concrete frame. The spacing between adjacent wind-resistant columns 3 in the middle is recommended to be no more than 4.5m. When a large opening is opened in the corrugated steel plate enclosure structure, the wind-resistant columns 3 should be set according to the layout of the opening. The two ends of the wind-resistant column 3 are respectively welded to the frame beams 2 on the upper and lower sides, and the outer edge of the wind-resistant column 3 is flush with the outer surface of the frame column 1. Several purlins 4 are arranged between two adjacent wind-resistant columns 3 and are parallel to the frame beam 2. The outer edge of the purlin 4 is also flush with the outer surface of the frame column 1. The distance between the bottom purlin 4 and the lower frame beam 2 is 50mm, the distance between the second purlin from the top and the frame beam 2 is 1200mm, and the distance between the top purlin 4 and the upper frame beam 2 is 100mm. The middle adjacent purlins 4 are arranged at equal intervals, and the interval is generally 1500mm to 2000mm. The two ends of the purlin 4 are welded to the two adjacent wind-resistant columns 3, and the two horizontally adjacent purlins 4 are arranged on the same horizontal line. A diagonal brace assembly 5 is provided between the upper and lower adjacent purlins 4, and the diagonal brace assembly 5 is used to improve the overall rigidity of the entire assembled support structure. Therefore, the assembled support structure of the utility model is arranged in the concrete frame, and the outer edge line of the entire support structure is flush with the outer side of the concrete frame and is on the same plane, without occupying additional area outside the concrete frame, and the facade is beautiful and has good integrity.The assembled support structure of the utility model adopts the overall assembly technology. The whole support structure is processed and manufactured in the factory, then transported to the construction site, and hoisted into the concrete frame. The wind-resistant column 3 is welded to the frame beam 2. Compared with the prior art purlin 4 which is set up separately, the rigidity is small and the deformation is large under the action of wind load. Due to construction errors, it is difficult to ensure that the facade is absolutely flush. The assembled support structure of the utility model is manufactured in the factory to ensure that the outside of each rod is flush. A diagonal brace assembly 5 is provided to improve the overall rigidity and significantly reduce the number of connection nodes with the concrete frame. It only needs to weld the wind-resistant column 3 to the frame beam 2, which reduces the number of embedded parts and reduces the workload of on-site welding. At the same time, it also reduces the construction defects caused by the position deviation of the embedded parts. The overall assembled installation reduces the quality control points in the high-altitude installation process, which is beneficial to on-site construction and quality control.

[0023] Embodiment 2:

[0024] See attached Figure 1 . On the basis of the first embodiment, the diagonal bracing assembly 5 includes a plurality of diagonal bracing rods 6; a plurality of the diagonal bracing rods 6 are arranged in a continuous "V" shape between the upper and lower adjacent purlins 4; the two ends of the diagonal bracing rods 6 are respectively welded and connected to the upper and lower purlins 4. It can be seen from the above structure that the diagonal bracing assembly 5 is composed of a plurality of diagonal bracing rods 6, and the diagonal bracing assembly 5 is arranged between the upper and lower adjacent purlins 4, each diagonal bracing rod 6 is not perpendicular to the adjacent upper and lower purlins 4, and the two ends are respectively welded and connected to the upper and lower purlins 4, and the entire diagonal bracing assembly 5 is in a continuous "V" shape after welding. An assembled support structure can only be provided with diagonal bracing assemblies 5 between the upper and lower adjacent purlins 4 in the middle position, and the centers of these diagonal bracing assemblies 5 are on a straight line and are arranged in the horizontal direction through the entire length, such as Figure 1 As described above, the overall rigidity of the supporting structure is improved, and deformation of the supporting structure during hoisting and use is prevented.

[0025] Supports are provided at both the upper and lower ends of the wind-resistant column 3; the supports are used to connect the wind-resistant column 3 with the embedded parts in the frame beam 2. It can be seen from the above structure that after the entire support structure is hoisted in place, the support at the upper end of the wind-resistant column 3 is connected to the embedded parts of the upper frame beam 2, and the support at the lower end of the wind-resistant column 3 is connected to the embedded parts of the lower frame beam 2, so that the entire support structure is installed in the concrete frame. Compared with the existing support structure, the assembled support structure of the utility model only connects the two ends of the wind-resistant column 3 with the concrete frame structure, and the number of connection nodes between the two is significantly reduced, and the number of embedded parts is reduced. Compared with the existing support structure, it not only reduces the workload of on-site welding, but also reduces the construction defects caused by the position deviation of the embedded parts, improves the connection fault tolerance rate, and is beneficial to on-site construction and quality control.

[0026] It also includes a safety net 7; the safety net 7 is arranged between the two lowest purlins 4; the safety net 7 is composed of a plurality of mutually perpendicular rods. As can be seen from the above structure, the safety net 7 is arranged at the bottom of the entire supporting structure. Counting the purlins 4 from the bottom to the top, the first purlin is 250mm away from the lower frame beam, and the second purlin is 1200mm away from the lower frame beam. The safety net 7 is arranged between the first purlin and the second purlin. The safety net 7 is composed of a number of mutually perpendicular rods, wherein the rods are square steel tubes B30x2, the spacing of the vertical rods is 1000mm, the spacing of the horizontal steel tube rods is 350mm, the two ends of the vertical rods are respectively welded to the first purlin and the second purlin, the two ends of the horizontal rods are respectively welded to the outermost wind-resistant columns 3, and the vertical rods and the horizontal rods are welded to each other at the intersection, so that the first purlin and the second purlin respectively replace the upper cross bar and the bottom skirting board of the railing, and are integrated with the assembled support structure, without the need to set up additional embedded parts and connectors for installing the railing.

[0027] A lifting lug plate 8 is welded in the middle of the wind-resistant column 3; the lifting lug plate 8 is used as a temporary lifting point during the lifting and installation construction. From the above structure, it can be seen that the lifting lug plate 8 is a temporary lifting point for the entire support structure during the lifting and installation construction. It is welded in the middle of the wind-resistant column 3, so that when the entire support structure is lifted, the force is more uniform and more stable.

[0028] Embodiment three:

[0029] See attached Figure 1 . On the basis of the second embodiment, the wind-resistant column 3 and the purlin 4 are both made of square steel pipes or rectangular steel pipes. From the above structure, it can be seen that the wind-resistant column 3 and the purlin 4 are both made of square steel pipes or rectangular steel pipes. Compared with the existing open-section H-shaped steel or C-shaped steel, the square steel pipe or rectangular steel pipe is a closed-section steel, the cross-sectional size of the rod is small, and the space occupied is relatively small, which makes it easier for the entire structure to be set in a concrete frame, and the closed-section steel pipe can avoid the accumulation of waste or dust during construction and production, and is more conducive to the cleaning of pollutants.

[0030] The diagonal bracing rod 6 is made of a thin-walled square steel pipe. As can be seen from the above structure, the diagonal bracing rod 6 is made of a thin-walled square steel pipe, which has strong pressure resistance, high bending strength and is easy to be welded and connected with other structures.
