Description

Technical Field

[0001] The present invention belongs to the technical field of steel-concrete frame structures, and in particular relates to a self-resetting shock-absorbing modular structure, a frame and a construction method thereof. Background Art

[0002] Special-shaped steel-concrete columns have excellent load-bearing capacity and are widely used in high-rise and super-high-rise buildings. However, they are difficult to construct on-site, have long construction cycles, and are significantly affected by environmental factors. Modular construction allows for simultaneous construction and fabrication, shortening overall construction time. Reduced on-site workload requires fewer workers, alleviating labor shortages. Precise factory-controlled manufacturing processes enhance quality control. Mass production of components allows for economies of scale, saving costs. However, in high-rise and super-high-rise buildings, lower-level columns are subject to significant forces. Steel columns would require stiffening ribs to prevent instability, while concrete columns would require a larger cross-sectional area. Therefore, special-shaped steel-concrete columns can address this shortfall. They also increase interior space and facilitate construction connections. Furthermore, since modular buildings require complete transportation and use, they must ensure overall stability during transportation and use, as well as ensure seismic performance during operation.

[0033] 1. Fast construction speed

[0034] The present invention adopts modular structure technology to manufacture the modular structure of the building in the factory and transport it to the site for assembly of each module to form a complete building. This process eliminates the process of on-site formwork and concrete pouring, reduces the amount of wet work on site, and simplifies the on-site construction process.

The teeth and disc springs ensure self-reset after support displacement, while the elliptical holes allow the frame supports to absorb shock during earthquakes by displacement. Adjusting the tightness of the bolts can adjust the stiffness and self-reset capability of individual frames.

[0037] 3. Cost savings

[0038] The wet work amount in the construction process of the present invention is small, and the on-site work mainly consists of hoisting and connection. The construction process is simple, so a large amount of labor is not required, thereby greatly reducing labor costs.

[0039] 4. Good integrity

The support and shock-absorbing bolts can be adjusted during transportation and use, thus ensuring the overall stability of the modular structure and facilitating transportation and use. Square steel tubes and U-shaped steel are used to connect the modules, which solves both vertical and horizontal connection problems between modules. BRIEF DESCRIPTION OF THE DRAWINGS

[0062] The embodiments of the present invention are described in detail below with reference to the accompanying drawings and examples.

[0063] refer to Figure 1 The present invention first provides a self-resetting, shock-absorbing modular structure assembled from special-shaped steel-concrete columns 1, I-beams 2, and supports 4 with shock-absorbing portions 5. Each self-resetting, shock-absorbing modular structure comprises four special-shaped steel-concrete columns 1 and eight I-beams 2. Supports 4 are diagonally connected between adjacent I-beams 2. The number of supports 4 can be determined based on the length of the I-beams 2 and the spacing between the upper and lower layers of I-beams 2. Four supports 4 are used in the figure, and are arranged only between the upper and lower layers of I-beams 2 in the horizontal X-direction.

[0064] The self-resetting shock-absorbing modular structure of the present invention can be applied to medium and high-rise buildings with simple internal partitions, can effectively shorten the construction period, and reduce the amount of wet work on site.

[0065] refer to Figure 2 、 Figure 3 and Figure 4 As shown, each support 4 is assembled by two pairs of processing angle steels 6 and a processing connecting plate 7 set at intervals. The two ends of the processing connecting plate 7 are respectively clamped between the two adjacent pairs of processing angle steels 6. The clamping part of the processing angle steel 6 and the clamped part of the processing connecting plate 7 are matched through a tooth structure. The pair of processing angle steels 6 clamping the same end of the processing connecting plate 7 are connected to the end of the processing connecting plate 7 by bolts 18 and elliptical long holes 20. The bolts 18 are ordinary bolts. The elliptical long holes 20 are opened at the connection between the processing angle steel 6 and the processing connecting plate 7. The length direction of the elliptical long holes 20 is consistent with the length direction of the support 4, so that the clamped part and the clamping part can slide relative to each other along the length direction of the support 4 to form a shock-absorbing part 5. The self-resetting function of the present invention is achieved by the disc spring 19 set at the end of the bolt 18. The disc spring 19 can be set at both ends or at one end, preferably at the left and right ends, to facilitate the self-resetting of the structure after deformation.

[0066] The tooth-shaped structure of the application, in particular, the clamping part of the angle steel 6 has a first tooth-shaped structure, the clamped part of the connecting plate 7 has a second tooth-shaped structure, the tooth length direction of the first tooth-shaped structure and the second tooth-shaped structure is perpendicular to the length direction of the support 4, and the tooth groove of the first tooth-shaped structure and the second tooth-shaped structure is matched, so that the angle steel 6 and the connecting plate 7 can be engaged with each other along the length direction of the support 4, can slide relative to each other along the length direction under stress, and can be self-reset under the action of the bolt 18 and the disc spring 19. The application uses the cooperation of the tooth-shaped structure and the disc spring 19 to extrude the angle steel 6 and the connecting plate 7 back to the original position, so as to realize the damping and self-resetting functions.

A part of space 17 with a length of about 20 cm is left at both ends of the column, and the part of space 17 is not provided with the cladding concrete 3, so as to facilitate the connection between the modules. The end plate 10 is L-shaped, is arranged at both ends of the column, and seals the inner side of the web of the T-shaped steel 16 and the inner side of the web of the I-shaped steel 15. In order to realize the connection of the upper and lower self-resetting damping modular structures, a plurality of vertical bolt holes are formed in the end plate 10, and in order to realize the connection of the horizontal self-resetting damping modular structures, a plurality of horizontal bolt holes are formed in the webs of the I-shaped steel 15 and the T-shaped steel 16 at the space 17.

Corresponding bolt holes are provided at both ends of the I-steel beam 2 to facilitate the connection between the I-steel beam 2 and the steel-concrete special-shaped columns 1. Among them, the inner flange of the I-steel 15 and the flange of the T-steel 16 are connected to the end of the I-steel beam 2 through a rectangular connecting plate 26 to form a basic module frame. One vertical edge of the rectangular connecting plate 26 is welded to the flange of the I-steel 15 or the flange of the T-steel 16, and the plate surface is in contact with the web of the I-steel beam 2 and connected with bolts.

[0085] The construction method of the self-resetting shock-absorbing frame of the present invention mainly includes the following steps:

[0086] In the factory, S1, I-beams 15 and T-beams 16 are welded, then formwork is installed and concrete is poured. After the concrete reaches a certain strength, the overcoat 3 is removed from the formwork and cured, forming a preliminary steel-concrete special-shaped column. During formwork, approximately 20 cm is left at both ends of the column's length. Concrete is not poured in this area to facilitate subsequent connection between modules.

[0087] S2. In the factory, uncast concrete parts are reserved at both ends of the preliminary steel-concrete special-shaped column as space 17, bolt holes are opened in the webs of the I-beam 15 and the T-beam 16 corresponding to the space 17, and two end plates 10 with bolt holes are welded to facilitate the connection between the modules to form the steel-concrete special-shaped column 1.

[0088] S3, in the factory, the steel reinforced concrete special-shaped column 1 and the I-shaped steel beam 2 are bolted by using the rectangular connecting plate 26 to form a basic frame. The rectangular connecting plate 26 between the beam and the column is connected by welding with the steel reinforced concrete special-shaped column 1 and is connected by bolting with the I-shaped steel beam 2.

[0089] S4, in the factory, the processed angle steel 6 and the processed connecting plate 7 are toothed and an elliptical long hole 20 is formed at the connecting position, and the bolt 18 and the disc spring 19 are used for connection to form the support 4 with the damping part 5. The toothed processing at the connecting position of the processed angle steel 6 and the processed connecting plate 7 needs to be matched with each other, and then the elliptical long hole 20 is formed at the processing position, and the two components are connected by using the bolt 18 and the disc spring 19. During the connection process, the disc spring 19 is placed between the bolt 18 and the component to form the support 4 with the damping part 5.

[0090] S5, in the factory, the support 4 with the damping part 5 is welded with the upper and lower adjacent I-shaped steel beams 2 by using the connecting steel plate 1 8 and the connecting steel plate 2 9 to obtain the self-centering damping modular structure. The damping part 5 can adjust the self-centering ability by adjusting the tightness of the bolt 18.

[0091] S6, the self-centering damping modular structure produced in the factory is transported to the construction site.

[0092] S7, on site, the self-centering damping modular structure is connected horizontally and vertically by using the connecting pieces, and in this process, the connecting pieces are connected with the corresponding web plate at the upper and lower end space 17 of the column.
