Description

Technical Field

[0001] The 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] Steel concrete special-shaped columns have good bearing capacity and are widely used in high-rise and super-high-rise buildings. However, they are difficult to construct on site, have a long construction period, and are greatly affected by the environment. Modular buildings allow for simultaneous construction and manufacturing, which shortens the overall construction time; due to the reduced workload on site, fewer workers are needed on site, which alleviates the labor shortage; quality control is strengthened through precise factory control of the manufacturing process; and economies of scale can be achieved through mass production of components, thereby saving costs. However, in high-rise and super-high-rise buildings, the forces borne by the lower columns are relatively large. If steel columns are used, stiffening ribs need to be added to prevent instability. If concrete columns are used, the cross-sectional area needs to be increased. Therefore, steel concrete special-shaped columns are used to fill the gap, and the use of steel concrete special-shaped columns can increase indoor space and facilitate construction connections. In addition, since modular buildings need to be transported and used as a whole, it is necessary to ensure overall stability during transportation and use, as well as seismic performance during use.

[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, which is assembled from a steel-concrete special-shaped column 1, an I-shaped steel beam 2 and a support 4 with a shock-absorbing part 5. For a self-resetting shock-absorbing modular structure, it has four steel-concrete special-shaped columns 1 and eight I-shaped steel beams 2. The support 4 is obliquely connected between the upper and lower adjacent I-shaped steel beams 2, and the number of the supports 4 can be determined according to the length of the I-shaped steel beam 2 and the spacing between the upper and lower layers of the I-shaped steel beams 2. Four supports 4 are used in the figure, and are only arranged between the upper and lower layers of the I-shaped steel 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 improve 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 arranged at intervals. The two ends of the processing connecting plate 7 are respectively clamped between the two adjacent pairs of processing angle steels 6, and the clamping part of the processing angle steel 6 cooperates with the clamped part of the processing connecting plate 7 through a toothed structure. The pair of processing angle steels 6 clamping the same end of the processing connecting plate 7 is connected to the end of the processing connecting plate 7 through a bolt 18 and an elliptical long hole 20. The bolt 18 is an ordinary bolt. The elliptical long hole 20 is opened at the connection between the processing angle steel 6 and the processing connecting plate 7, and its length direction 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 realized 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, so as to facilitate the self-resetting of the structure after deformation.

[0066] The tooth structure coordination of the present invention specifically refers to that the clamping portion of the processing angle steel 6 has a first tooth structure, and the clamped portion of the processing connecting plate 7 has a second tooth structure, and the tooth length directions of the first tooth structure and the second tooth structure are perpendicular to the length direction of the support 4, and the tooth grooves of the first tooth structure and the second tooth structure match, so that they can bite each other along the length direction of the support 4, and can slide relatively along the length direction when subjected to force, and the deformed structure can self-reset under the action of the bolt 18 and the disc spring 19. The present invention utilizes the coordination of the tooth structure and the disc spring 19 to squeeze the relatively sliding processing angle steel 6 and the processing connecting plate 7 back to their original positions, thereby achieving shock absorption and self-reset functions.

[0067] refer to Figure 5 The steel-concrete special-shaped column 1 of the present invention mainly includes an I-shaped steel 15, a T-shaped steel 16, a coating concrete 3 and an end plate 10. The T-shaped steel 16 is arranged in parallel with the I-shaped steel 15, and the web of the T-shaped steel 16 is vertically welded to the inner side of the web of the I-shaped steel 15. The coating concrete 3 is arranged between the upper and lower flanges of the I-shaped steel 15 and between the web of the I-shaped steel 15 and the flange of the T-shaped steel 16. Ordinary concrete can be used, and the cross-section of the rear column is T-shaped. A part of the space 17 with a length of about 20 cm is reserved at both ends of the column. The coating concrete 3 is not arranged in the part of the space 17, which is convenient for the connection between the modules. The end plate 10 is L-shaped and is arranged at both ends of the column to block 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 shock-absorbing modular structures, a plurality of vertical bolt holes are opened on the end plate 10, and in order to realize the connection of the horizontal self-resetting shock-absorbing modular structure, a plurality of horizontal bolt holes are opened in the webs of the I-shaped steel 15 and the T-shaped steel 16 at the space 17.

After the basic module frame is formed, the support 4 with the shock absorbing part 5 is connected to the basic module frame by connecting steel plate 1 8 and connecting steel plate 2 9, thereby forming a self-resetting shock absorbing module structure based on steel concrete special-shaped columns.

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

[0086] S1, in the factory, the I-shaped steel 15 and the T-shaped steel 16 are welded, and the formwork is supported, and concrete is poured. After the concrete reaches a certain strength, the covering concrete 3 is obtained, and the formwork is removed and cured to form a preliminary steel-concrete special-shaped column. When supporting the formwork, it is necessary to leave about 20 cm at both ends of the column in the length direction, and concrete is not poured in this part. This setting facilitates the connection between subsequent 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 modules to form a steel-concrete special-shaped column 1.

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

[0089] S4, in the factory, the connection between the processed angle steel 6 and the processed connecting plate 7 is processed into teeth and an elliptical long hole 20 is opened, and the bolts 18 and the disc springs 19 are used to connect them to form a support 4 with a shock absorbing part 5. The teeth processing at the connection between the processed angle steel 6 and the processed connecting plate 7 only needs to match each other, and then the elliptical long hole 20 is opened at the processing, and the two components are connected by bolts 18 and disc springs 19. During the connection process, the disc spring 19 is placed between the bolts 18 and the components to form a support 4 with a shock absorbing part 5.
