Description

Technical Field

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

[0002] 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 existing supporting and fixing structure mainly consists of vertical wind-resistant columns and horizontal purlins, such as Figure 1 As described above, after the rod hanging device is positioned in a predetermined position, the on-site workers manually adjust the bottom of the wind-resistant column of the color plate support structure to contact the embedded part, and set a circle of fillet welds between the bottom of the wind-resistant column of the color plate support structure and the embedded part. After the bottom welding construction is completed, the top of the bottom of the wind-resistant column of the color plate support structure is connected to the top embedded part by bolts to form a complete color plate support structure. This connection node has the following problems:

[0003] ① Low construction accuracy. The crane hoisting construction accuracy is low. The construction error required for concrete is within 5mm, while the bolt connection construction accuracy is 0.5-1mm. It is difficult to accurately hoist the color plate support structure to the predetermined position, it is difficult to ensure that the bolts can be accurately installed in place, and it is difficult to achieve the preset construction accuracy.

[0004] ②Slow construction speed. After the crane is hoisted into place, the structure needs to be manually adjusted by manpower. Since the color plate support structure is heavy, it is difficult to adjust and takes a long time, which greatly affects the speed of construction.

[0005] ③ The structure has potential safety hazards. Hoisting, installation and welding require a certain amount of time. If there is a sudden wind during the welding process, the color plate support structure may shake, affecting the quality of welding. Under extreme working conditions, there may be a risk of insufficient weld strength and structural damage.

[0006] In recent years, as the country has put forward new and higher requirements for environmental protection and safe production, the existing supporting fixed structure has been technically improved and upgraded, and an assembled supporting enclosure structure has been adopted, such as Figure 2As shown, the entire supporting enclosure structure is processed and manufactured in the factory, then transported to the construction site, and then hoisted to the installation location. The supporting enclosure structure is connected to the embedded parts in the concrete frame through the connection nodes on the wind-resistant columns. The connection construction between the connection nodes on the wind-resistant columns and the embedded parts is the main work of the on-site installation and construction. The construction quality of the node connection determines whether the structural force form is reasonable, whether the supporting enclosure structure is beautiful and applicable after the construction is completed, and whether the overall construction progress meets the expected construction period. If the existing connection nodes are used again, the above problems will occur, the construction accuracy is low, the construction speed is slow, and there may be safety hazards in the structure. Therefore, setting reasonable connection nodes is of great benefit to the design, construction and use of prefabricated supporting enclosure structures. Utility Model Content

[0007] The purpose of this utility model is to provide a connection node of an assembled support enclosure structure to address the above shortcomings, and to solve the problem of how to quickly position and connect the assembled support enclosure structure with the concrete frame, which not only ensures the construction speed and construction accuracy, but also ensures the structural safety during construction, and improves the construction efficiency and construction quality.

[0014] The beneficial effects of the utility model are:

It can be seen from the above structure that the concrete frame structure is a rectangular structure composed of two upper and lower parallel concrete frame beams and two left and right parallel concrete frame columns, and the assembled supporting enclosure structure is mainly composed of a vertical wind-resistant column 1 and a horizontal purlin 18, such as Figure 2 As shown. The entire supporting enclosure structure is manufactured in the factory in advance, then transported to the site, and finally installed in the concrete frame. The installation of the assembled supporting enclosure structure is mainly through connecting the upper and lower ends of the wind-resistant column 1 in the supporting enclosure structure with the upper and lower concrete frame beams 3 through connecting nodes. The connecting node includes a column bottom support 4 and a column top sliding support 5. The column top sliding support 5 is arranged at the top of the wind-resistant column 1.

[0028] Embodiment 2:

[0029] See attached Figures 3 to 5 . On the basis of the first embodiment, the column bottom support 4 includes a bottom plate 8 and a first baffle 9; the bottom surface of the bottom plate 8 is connected to the first embedded part 6; a first baffle 9 is provided on one side of the top surface of the bottom plate 8; the first baffle 9 is perpendicular to the bottom plate 8; a second baffle 10 is provided on the second embedded part 7; the second baffle 10 is perpendicular to the second embedded part 7; the first baffle 9 and the second baffle 10 are located on the same side of the wind-resistant column 1. It can be seen from the above structure that the column bottom support 4 includes a bottom plate 8 and a first baffle 9, the bottom plate 8 is connected to the first embedded part 6 on the downward side, and the first baffle 9 is welded on the left or right side of the upward side, the first baffle 9 is perpendicular to the bottom plate 8, and the first baffle 9 is used to position the bottom end of the wind-resistant column 1. A second baffle 10 is provided on the left or right side of the second embedded part 7, and the second baffle 10 is perpendicular to the second embedded part 7. The second baffle 10 is used to position the top of the wind-resistant column 1, so the side of the first baffle 9 located on the bottom plate 8 and the side of the second baffle 10 located on the second embedded part 7 correspond to each other. When the assembled support structure is hoisted into the concrete frame for installation, the first baffle 9 and the second baffle 10 can quickly position the assembled support enclosure structure. At this time, it is only necessary to place the sliding support at the upper end of the wind-resistant column 1 against the second baffle 10, and the bottom end of the wind-resistant column 1 against the first baffle 9, so that the assembled support structure can be quickly positioned. The connection node of the utility model can allow the assembled support enclosure structure to be quickly hoisted into place, reduce the time for crane and manual adjustment, improve the use efficiency of the crane, greatly increase the construction speed, maximize the benefits of assembly, and make the installation of the support enclosure structure more accurately installed to the predetermined position, so that the entire frame is on the same plane after the construction is completed, making the facade more beautiful.

[0030] The column base support 4 also includes a pin 11; a pin 11 is provided in the middle of the top surface of the base plate 8; a column base sealing plate 12 is provided at the bottom end of the wind-resistant column 1; an opening 13 is provided in the middle of the column base sealing plate 12; the pin 11 passes through the opening 13 and is inserted into the wind-resistant column 1; the base plate 8 is connected to the column base sealing plate 12. It can be seen from the above structure that a pin 11 is provided in the middle position of the upward side of the bottom plate 8, and a column foot sealing plate 12 is provided at the bottom end of the wind-resistant column 1. The size of the column foot sealing plate 12 is the same as the cross-sectional size of the wind-resistant column 1. An opening 13 is provided in the middle position of the column foot sealing plate 12, and the size of the opening 13 is slightly larger than the size of the pin 11, so that the pin 11 passes through the opening 13 and enters the wind-resistant column 1. When the wind-resistant column 1 is hoisted into the concrete frame and positioned by the first baffle 9 and the second baffle 10, the pin 11 is inserted into the wind-resistant column 1 through the opening 13 of the column foot sealing plate 12, and the entire supporting enclosure structure is further positioned and initially fixed, and then the bottom plate 8 and the column foot sealing plate 12 are welded.

[0031] The column top sliding support 5 includes a top plate 14, a limit plate 15, a column top sealing plate 16 and a sliding rod 17; the upper end of the sliding rod 17 is provided with a top plate 14, and the lower end is provided with a limit plate 15; the sliding rod 17 is covered with a column top sealing plate 16; the column top sealing plate 16 moves freely on the sliding rod 17; the top plate 14 is connected to the second embedded part 7; the column top sealing plate 16 is connected to the upper end of the wind-resistant column 1. It can be seen from the above structure that the column top sliding support 5 includes a top plate 14, a limit plate 15, a column top sealing plate 16 and a sliding rod 17, the top plate 14 and the limit plate 15 are welded to the upper end and the lower end of the sliding rod 17 respectively, the axis of the sliding rod 17 is located on the same straight line as the center of the top plate 14 and the limit plate 15, the length of the sliding rod 17 is generally 150mm, and the size of the limit plate 15 is smaller than the cross-sectional size of the wind-resistant column 1. A column top sealing plate 16 is also sleeved outside the sliding rod 17. A through hole is provided in the middle of the column top sealing plate 16. The sliding rod 17 is located in the through hole. The size of the through hole is slightly larger than the cross-sectional size of the sliding rod 17. The column top sealing plate 16 can slide freely on the sliding rod 17. Since a top plate 14 and a limit plate 15 are provided at both ends of the sliding rod 17, the column top sealing plate 16 only moves on the sliding rod 17. The top sliding support is first manufactured in the factory. The wind-resistant column 1 is made of square steel pipe or rectangular steel pipe.

The size of the top plate 14 is smaller than the size of the top sealing plate 16. When the supporting enclosure structure is hoisted into the concrete frame for installation, the top end of the wind-resistant column 1 is positioned by the top sealing plate 16 against the second baffle 10. Finally, the top plate 14 is welded to the second embedded part 7 to connect the wind-resistant column 1 to the upper concrete frame beam 2. Since the sliding rod 17 can freely extend and retract through the hole, the sliding support can release the axial force transmitted from the frame beam.

[0032] Embodiment three:

[0033] See attached Figures 3 to 5 Based on the second embodiment, the pin 11 is made of round steel. As can be seen from the above structure, the pin 11 is generally made of round steel with a diameter of 30 mm. The diameter can be adjusted appropriately according to the size of the wind-resistant column 1, and the height is generally the same as the height of the first baffle 9.

[0034] The sliding rod 17 is made of a steel pipe. As can be seen from the above structure, the sliding rod 17 is made of a steel pipe, generally a steel pipe with a pipe diameter of 42 mm and a wall thickness of 4 mm.
