Description

Technical Field

[0001] This utility model relates to the field of container house technology, specifically to a large-span beam-column rigid connection structure that can continuously adjust the installation position of the partition columns according to the functional module requirements. Background Technology

[0002] Modular building systems are widely used in various scenarios due to their significant advantages in prefabricated construction technology. However, they face systemic technical constraints in the integrated application of large-span, multi-functional spaces. There is a structural contradiction between the existing standard modular system of steel beams and columns and the spatial requirements of heterogeneous functional units. Differences in the standardized modular matrices of different functional modules lead to the need for reconfiguration of force transmission paths, resulting in a surge in the number of redundant force transmission components. This leads to a large number of repetitive load-bearing components, causing significant material waste and a substantial increase in construction costs. Excessive redundant force transmission components also cause excessive interference during on-site assembly, hindering assembly efficiency. Utility Model Content

[0003] This utility model proposes a large-span beam-column rigid connection structure with adjustable-position partition columns. Its purpose is to solve the problem of material waste and installation interference caused by the structural contradiction between the existing standard modular system of steel beams and columns and the spatial requirements of multifunctional units, which leads to an increase in the number of redundant force transmission components.

[0004] The technical solution of this utility model is as follows:

[0005] A large-span rigid beam-column structure with adjustable partition columns includes parallel left and right side columns and steel beams connecting the left and right side columns. The steel beams include a first steel beam and a second steel beam, with the first steel beam located above the second steel beam. An inner partition column is hinged between the first and second steel beams. The upper end of the inner partition column has an installation groove for the first steel beam to pass through. The top plate of the installation groove is detachably connected to the first steel beam by bolts. The top plate has a channel for the web of the first steel beam to pass through. The inner partition column is bolted to the second steel beam by a column base connecting plate fixed at its lower end. The installation position of the inner partition column can be continuously adjusted along the length of the steel beam.

[0006] Furthermore: The steel beam includes an upper flange plate, a lower flange plate, and a web plate. Both the upper flange plate and the lower flange plate have outwardly extending insertion ends at their left and right ends, which are connected through the side column. A first middle flange plate extending into the frame and beyond the rear side of the side column, and a second middle flange plate extending outward and flush with the front side of the side column are fixed on the web plate between the upper flange plate and the lower flange plate. The extension length of the first middle flange plate is greater than the extension length of the second middle flange plate. The left and right end faces of the first middle flange plate and the second middle flange plate are in contact with the corresponding side faces of the corresponding side columns.

[0007] Furthermore: the mounting groove includes two inverted L-shaped support plates symmetrically arranged parallel to the length direction of the steel beam. The horizontal plate at the upper end of the inverted L-shaped support plate is used to support the middle flange plate of the steel beam. The first middle flange plate and the second middle flange plate are respectively bolted to the corresponding side of the inverted L-shaped support plate. A column top sealing plate is fixed at the bottom of the mounting groove.

[0008] Furthermore: the middle part of the column base connecting plate is a sealing part that conforms to the outer contour of the cross-section of the inner partition wall column, and the left and right sides of the sealing part are connecting parts, through which the inner partition wall column is bolted to the second steel beam.

[0009] Compared with the prior art, the present invention has the following advantages:

[0010] (1) This utility model adjusts the division of functional modules in the space by setting an internal partition wall with continuously adjustable installation position inside the rigid beam-column connection structure. While ensuring functional requirements, it greatly reduces redundant force transmission components, thereby reducing material waste and lowering the total construction cost. At the same time, it can reduce installation interference and improve assembly efficiency.

[0011] (2) The steel beams in the length direction of the frame structure of this utility model are rigidly connected, which can effectively improve the planar stiffness of the structure and reduce the deflection of the steel beams at the beam-column connection ends. Combined with the internal partition wall columns that are hinged to the steel beams, the mid-span deflection of the steel beams is further reduced. Without increasing the cross-sectional dimensions of the steel beams, it can meet both the stress requirements of the structure itself and the installation requirements of the building's finishing layer.

[0012] (3) In this utility model, the inverted L-shaped support plates symmetrically arranged on both sides of the steel beam at the upper end of the internal partition wall divider column form an installation groove for the steel beam to pass through. The upper horizontal plate of the inverted L-shaped support plate is used to support the first middle flange plate and the second middle flange plate of the steel beam. A channel for the web plate of the steel beam to pass through is left between the two inverted L-shaped support plates. Attached Figure Description

Detailed Implementation

[0023] The technical solution and effects of this utility model will be described in detail below with reference to the embodiments and accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0024] like Figure 1 As shown, a large-span rigid beam-column structure with adjustable partition columns includes parallel left and right side columns 110 and steel beams connecting the left and right side columns 110. The steel beams include a first steel beam and a second steel beam, with the first steel beam located above the second steel beam. An inner partition wall partition column 120 is hinged between the first steel beam and the second steel beam. (Combined with...) Figure 2 , Figure 3 and Figure 4As shown, the side column 110 is preferably a square steel tube with elongated holes. The steel beam includes an upper flange plate 211, a lower flange plate 214, and a web plate 215. Both ends of the upper flange plate 211 and the lower flange plate 214 have outwardly extending insertion ends, which are connected through the side column 110. A first middle flange plate 212 extending inwards and beyond the rear side of the side column 110, and a second middle flange plate 213 extending outwards and flush with the front side of the side column 110, are fixed on the web plate 215 between the upper flange plate 211 and the lower flange plate 214. The extension length of the first middle flange plate 212 is greater than that of the second middle flange plate 213, used to support the floor slab 300. The left and right end faces of the first middle flange plate 212 and the second middle flange plate 213 contact the corresponding sides of the corresponding side column 110. Bolt holes are provided on both the first middle flange plate 212 and the second middle flange plate 213. The upper flange plate 211 and the lower flange plate 214 of the steel beam are provided with plug-in ends at both ends. The plug-in ends pass through the corresponding elongated holes on the side column 110 to the left and right and are then welded firmly. The left and right end faces of the first middle flange plate 212 and the second middle flange plate 213 are in contact with the corresponding side faces of the corresponding side columns 110.

[0025] Specifically, such as Figure 5 , Figure 6 and Figure 7 As shown, the upper end of the inner partition wall dividing column 120 is provided with an installation groove 123 for the first steel beam to pass through, and the lower end is fixed with a column base connecting plate 121 for bolting to the upper flange plate 211 of the second steel beam. As a preferred embodiment of this utility model, such as... Figure 8 As shown, the mounting groove 123 includes two inverted L-shaped support plates 1231 symmetrically arranged in the length direction of the steel beam, parallel to the length direction of the steel beam. The horizontal plate at the upper end of the inverted L-shaped support plate 1231 is used to support the middle flange plate of the steel beam. The first middle flange plate 212 and the second middle flange plate 213 are respectively bolted to the corresponding side of the inverted L-shaped support plate 1231. A column top sealing plate 122 is fixed at the bottom of the mounting groove 123.

[0026] like Figure 9 As shown, the middle of the column base connecting plate 121 is a sealing part that is adapted to the cross-section of the inner partition wall dividing column 120. The left and right sides of the sealing part are connecting parts. The inner partition wall dividing column 120 is bolted to the second steel beam through the connecting parts.

[0027] During workshop processing, the required steel beams and side columns 110 are first processed according to the drawings. Then, the inner partition wall columns 120 are processed. The specific method is as follows: cut the two opposite pipe walls of the inner partition wall columns 120 along the length of the inner partition wall columns 120. After cutting, weld the column top sealing plate 122 to the top of the cut. Then, bend the two side walls into inverted L-shaped support plates 1231 and open bolt connection holes on the horizontal plate of the inverted L-shaped support plates 1231.

[0028] During assembly, the steel beam and one side column 110 are first pre-assembled on a horizontal workbench. The insertion end of the steel beam is inserted into the corresponding elongated hole of the side column 110. The plan layout is determined according to functional requirements, and the required number of internal partition columns 120 is determined. The internal partition columns 120 are pushed into the structural frame along the length of the steel beam and pre-fixed with bolts. Then, the insertion end of the other side column 110 is inserted and fixed to the corresponding side of the steel beam. The splicing node of the steel beam and the side column 110 is adjusted and calibrated and sent to the welding robot workstation. The contact point between the steel beam and the steel column is welded with fillet welds to complete the rigid connection between the side column 110 and the steel beam. The position of the internal partition column 120 is adjusted and calibrated, and the connecting bolts are tightened to complete the hinged connection between the upper and lower ends of the internal partition column 120 and the corresponding side steel beam.

[0029] It should be noted that, as will be apparent to those skilled in the art, this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. The scope of this utility model is defined by the claims rather than the foregoing description.
