The present invention solves the technical problem that the relative displacement between the module unit system and the additional lateral force resisting system is less than the damper starting displacement by rationally configuring the structural parameters of the scissor-type mechanism; solves the technical problem that the concentrated load of the damper causes damage to the floor slab by the coordinated cooperation of the damper, the support, and the scissor-type mechanism; and combines the expansion joint with the two-point connection damper into a connection structure that has both architectural and structural functions, and applies the connection structure to the connection between the module unit system and the additional lateral force resisting system, not only solving the technical problem of limited installation space, but also having relatively obvious comprehensive benefits and potential value.

Description

Technical Field

[0001] The invention relates to a novel modular structural system and belongs to the technical field of structural engineering. Background Art

[0002] Compared to traditional prefabricated structures, modular construction offers advantages such as faster construction, lower labor intensity, and energy conservation and environmental protection. In recent years, modular construction has been widely used in low-rise structures. These structures are typically assembled on-site from prefabricated modular units and connecting nodes. Due to the lightweight and standardized nature of these modular units, the application of modular structures in high-rise buildings often requires an additional lateral force-resisting system (either a frame system or a frame-and-bracing system) to meet seismic design requirements. Previous studies have shown that adding a lateral force-resisting system between modular units can effectively increase the maximum applicable height of modular structures.

[0003] In terms of structural construction, to ensure reliable force transmission between the modular unit system and the additional lateral force resisting system, common connection methods for the modular unit system and the additional lateral force resisting system are rigid connections (on-site welding or cast-in-place concrete connections) and flexible connections (damper connections). For rigid connections, using on-site welding or cast-in-place concrete connections can affect the interior design of the modular unit. For flexible connections, existing two-point connection dampers (such as buckling-restrained braces and viscous dampers) are difficult to directly apply to the connection between the modular unit system and the additional lateral force resisting system due to the distance between the modular unit system and the additional lateral force resisting system. Under horizontal earthquake action, placing two-point connection dampers directly on either side of the modular unit floor slab and the additional lateral force resisting system floor slab may cause stress concentration in the floor slab, thereby affecting the damper's efficiency. Furthermore, compared with the inter-story displacement of general building structures, the relative displacement between the modular unit system and the additional lateral force resisting system is smaller. Therefore, further research is needed to determine the flexible connection method suitable for connecting the modular unit system and the additional lateral force resisting system.

[0004] In terms of building construction, expansion joints are typically installed between the modular unit system floor slab and the additional lateral force resisting system to facilitate the passage of personnel between them and to prevent collisions during earthquakes. However, traditional expansion joints only have a construction function. Summary of the Invention

[0005] In order to overcome the problems in the prior art, the present invention proposes an energy dissipation and shock absorption system based on a module and frame combination connected by a scissor-type deformation joint. The energy dissipation and shock absorption system includes a module unit system, a frame system, and an X-direction scissor-type deformation joint and a Y-direction scissor-type deformation joint connected to the module unit system and the frame system respectively. The energy dissipation and shock absorption system solves the technical problem that the relative displacement between the module unit system and the additional lateral force resisting system is less than the damper starting displacement by rationally configuring the structural parameters of the scissor-type mechanism; solves the technical problem that the concentrated load of the damper causes damage to the floor slab by the coordinated cooperation of the damper, the support and the scissor-type mechanism; and combines the deformation joint with the two-point connection damper into a connection structure with both architectural and structural functions, and applies the connection structure to the connection between the module unit system and the additional lateral force resisting system, which not only solves the technical problem of limited installation space, but also has relatively obvious comprehensive benefits and potential value.

[0010] In some embodiments, the scissor-type deformation joint includes two relatively arranged supports, a slide plate and two scissor-type mechanisms installed between the two supports from top to bottom, a friction damper arranged between the two scissor-type mechanisms, and two limit assemblies connected to the two supports at the ends respectively; the scissor-type deformation joint is connected to the frame system and the corresponding module unit system through its two supports; the two ends of the friction damper extend to the outside of the corresponding limit assemblies respectively and are connected to the corresponding ends of the two scissor-type mechanisms; the two scissor-type mechanisms are respectively connected to the two supports for movement, so as to shorten or lengthen the friction damper, or cause the two supports to move relative to each other.

[0011] In some embodiments, the limiting assembly includes two A limiting steel plates arranged side by side along the width direction of the scissors-type deformation joint as a whole, two B limiting steel plates arranged side by side along the upper and lower directions of the scissors-type deformation joint as a whole, and one C limiting steel plate; two A limiting steel plates, two B limiting steel plates, and one C limiting steel plate are arranged in sequence along the length direction of the scissors-type deformation joint as a whole, and the C limiting steel plate and the two B limiting steel plates are respectively connected to each other in a movable manner along the width direction of the scissors-type deformation joint as a whole, and the two B limiting steel plates and the two A limiting steel plates are also respectively connected to each other in a movable manner along the width direction of the scissors-type deformation joint as a whole.

[0012] In some embodiments, two sides of the scissor mechanism are movably connected to two supports respectively, and two ends thereof are hingedly connected to two ends of the friction damper respectively.

[0013] In some embodiments, the scissors-type mechanism includes two multi-link structures that are alternately arranged up and down along the overall length direction of the scissors-type deformation joint; the multi-link structure includes two short links located at its two ends, and a plurality of long links located between the two short links; the corresponding long links in the two multi-link structures are alternately arranged up and down along the overall length direction of the scissors-type deformation joint; the short links and long links, as well as the long links and long links in the same multi-link structure are connected to the corresponding supports through B pins; the ends of the short links corresponding to the ends of the two multi-link structures are respectively connected to the ends of the friction damper through A pins.

[0014] In some embodiments, the two multi-link structures are further adapted to form a plurality of diamond-shaped telescopic structures sequentially arranged along the entire length direction of the scissor-type deformation joint.

[0022] Compared with the prior art, the technical solution of the present invention has at least the following beneficial effects:

[0023] For example, the combined use of X-direction scissor-type expansion joints and Y-direction scissor-type expansion joints can utilize the relative displacement between the module unit system and the frame system to achieve bidirectional energy dissipation and shock absorption. At the same time, the application of scissor-type expansion joints can also amplify the relative displacement between the module unit system and the frame system and reduce the load demand of the friction damper. Compared with directly installing the friction damper on both sides of the module unit system and the frame system, the scissor-type expansion joints of the present invention can convert the concentrated load of the friction damper into a uniformly distributed load, thereby avoiding damage to the floor slab under the action of concentrated force. In addition, the scissor-type expansion joints do not require holes to be opened in the floor slab during installation, nor do they require adjustment of the distance between the module unit system and the frame system. They can meet the restrictions on the installation space when the module unit system is connected to the frame system, and have relatively obvious comprehensive benefits and potential value.

[0042] 4-Screws. DETAILED DESCRIPTION

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0044] like Figure 1 As shown, an embodiment of the present invention provides an energy dissipation and vibration reduction system based on a module and frame combination connected by scissor-type deformation joints.

[0045] Specifically, the energy dissipation and vibration reduction system includes a module unit system 1, a frame system 2, and a scissor-type deformation joint 3 connecting the module unit system 1 and the frame system 2. The scissor-type deformation joint 3 includes an X-direction scissor-type deformation joint 3.X and a Y-direction scissor-type deformation joint 3.Y.

[0046] In a specific implementation, multiple module unit systems 1 are arranged in sequence around the frame system 2, and the module unit systems 1 located on the side of the frame system 2 are connected to the frame system 2 in the X-axis direction and the Y-axis direction through the X-direction scissor-type deformation joint 3.X and the Y-direction scissor-type deformation joint 3.Y respectively.

[0047] like Figure 2 and Figure 3 As shown, the modular unit system 1 specifically comprises an A-type modular unit 1.1 and a B-type modular unit 1.2. The A-type modular unit 1.1 is located at the bottom layer of the modular unit system 1, while the B-type modular unit 1.2 is located at the top layer of the modular unit system 1. The A-type modular unit 1.1 has one or more layers (at least two layers), while the B-type modular unit 1.2 has only one layer. The A-type modular unit 1.1 is used to construct the interior space of a building, while the B-type modular unit 1.2 is used to construct the roof of a building.

[0048] Furthermore, the specific composition of the A-type module unit 1.1 includes four A-module columns 1.1.1, four A-floor beams 1.1.2, one A-floor slab 1.1.3 and four A-ceiling beams 1.1.4.

[0049] In a specific implementation, for the same floor, four A floor beams 1.1.2 are connected in sequence to form an A floor beam frame, and four A ceiling beams 1.1.4 are connected in sequence to form an A ceiling beam frame. The A ceiling beam frame and the A floor beam frame are arranged up and down and connected in the vertical direction by four A module columns 1.1.1. The four A module columns 1.1.1 are respectively connected to the four corners of the A ceiling beam frame and the A floor beam frame.

[0050] Furthermore, the A module columns 1.1.1, A floor beams 1.1.2, and A ceiling beams 1.1.4 are all connected by welding, and the A floor slab 1.1.3 is connected to the four A floor beams 1.1.2 by integral concrete pouring; the bottom elevation of the A floor slab 1.1.3 is the same as the top elevation of the A floor beams 1.1.2.

[0051] The B-type modular unit 1.2 specifically comprises four B-module columns 1.2.1, four B-floor beams 1.2.2, and a B-floor slab 1.2.3. The four B-floor beams 1.2.2 are sequentially connected via the four B-module columns 1.2.1 to form a B-floor beam frame. The B-floor slab 1.2.3 is integrally connected to the four B-floor beams 1.2.2 via cast concrete. The bottom elevation of the B-floor slab 1.2.3 is the same as the top elevation of the B-floor beams 1.2.2, and the top elevation of the B-floor slab 1.2.3 is the same as the top elevation of the B-module columns 1.2.1. The B-floor beams 1.2.2 and B-module columns 1.2.1 are welded together.

[0052] like Figure 4 As shown, the frame system 2 specifically comprises frame columns 2.1, frame beams 2.2, and floor slabs 2.3. For each floor, four frame beams 2.2 are sequentially connected to form the frame of the frame system 2. Four frame columns 2.1 are connected to the corners of the frame system 2, and the floor slabs 2.3 are integrally connected to the four frame beams 2.2 through cast concrete. Furthermore, welded connections are used between the frame beams 2.2 and frame columns 2.1 on the same floor, and between the frame columns 2.1 on adjacent floors. The top elevation of the floor slabs 2.3 is the same as that of the top elevation of the A floor slabs 1.1.3 or the B floor slabs 1.2.3. The number of floors of the frame system 2 is the total number of the A-type modular units 1.1 and the B-type modular units 1.2.

[0053] like Figures 5 to 7 As shown, the specific components of the scissor-type deformation joint 3 include two supports 3.1, a slide plate 3.2, two limit assemblies 3.3, two A pins 3.4, a friction damper 3.5, two scissor mechanisms 3.6 and several groups of B pins 3.7.

[0054] Taking the Y-direction scissors-type expansion joint as an example, in a specific implementation, the two supports 3.1 extend along the Y-axis direction (i.e., the overall length direction of the Y-direction scissors-type expansion joint) and are symmetrically arranged in the X-axis direction (i.e., the overall width direction of the Y-direction scissors-type expansion joint); the slide 3.2 also extends along the Y-axis direction and is installed between the two supports 3.1; the two scissors-type mechanisms 3.6 also extend along the Y-axis direction and are symmetrically arranged in the Z-axis direction (i.e., the overall vertical direction of the Y-direction scissors-type expansion joint), and the two scissors-type mechanisms 3.6 are respectively connected to the two supports 3.1 via B pins 3.7; the friction damper 3.5 also extends along the Y-axis direction and is located between the two scissors-type mechanisms 3.6, and the two ends of the friction damper 3.5 are respectively connected to the two scissors-type mechanisms 3.6 at the end via an A pin 3.4; the two limit assemblies 3.3 extend along the X-axis direction and are symmetrically arranged in the Y-axis direction, and the two limit assemblies 3.3 are respectively welded to the two supports 3.1. The two scissor-type mechanisms 3.6 are both located below the slide plate 3.2.

[0055] The limit assembly 3.3 is used to eliminate the deadweight of the friction damper 3.5 and prevent the friction damper 3.5 from bending or twisting; the friction damper 3.5 is used to provide a restoring force; the scissor mechanism 3.6 is used to convert the restoring force of the friction damper 3.5 and transmit the restoring force to the support 3.1; the support 3.1 is used to transmit the restoring force to the module unit system 1 and the frame system 2; the slide 3.2 is used for personnel passage.

[0056] like Figure 8As shown, the support 3.1 includes a support oblong hole 3.1a, a support slide mounting groove 3.1b, and a support web circular hole 3.1c. Multiple support oblong holes 3.1a are arranged along the length of the support 3.1, i.e., the Y-axis direction, for connection to the scissor mechanism 3.6 via a B pin 3.7. Two support oblong holes 3.1a are provided in the Z-axis direction, corresponding to the two scissor mechanisms 3.6. The support slide mounting groove 3.1b is located above the support oblong hole 3.1a and extends along the length of the support 3.1, i.e., the Y-axis direction, for mounting the slide 3.2. The slide 3.2 can be inserted into the support slide mounting groove 3.1b. Multiple support web circular holes 3.1c are also arranged along the length of the support 3.1, i.e., the Y-axis direction, for fastening the scissor-type expansion joint 3 to the module unit system 1 and the frame system 2.

[0057] like Figure 9 As shown, the specific components of the limiting assembly 3.3 include two A limiting steel plates 3.3.1, two B limiting steel plates 3.3.2, one C limiting steel plate 3.3.4 and six C pin shafts 3.3.3.

[0058] The A limiting steel plate 3.3.1 includes two A limiting steel plate oblong holes 3.3.1a arranged side by side in the Z-axis direction, and the A limiting steel plate oblong holes 3.3.1a extend along the X-axis direction; the B limiting steel plate 3.3.2 includes a B limiting steel plate oblong hole 3.3.2b located in the middle and extending along the X-axis direction, and two B limiting steel plate circular holes 3.3.2a located at both ends thereof; the C limiting steel plate 3.3.4 includes a C limiting steel plate square hole 3.3.4a located in the middle, and two C limiting steel plate circular holes 3.3.4b located on both sides thereof along the Z-axis.

[0059] Furthermore, the diameters of the A limit steel plate oblong hole 3.3.1a, the B limit steel plate circular hole 3.3.2a, the B limit steel plate oblong hole 3.3.2b, and the C limit steel plate circular hole 3.3.4b are all the same as the diameter of the C pin shaft 3.3.3.

[0060] The two B limit steel plates 3.3.2 are arranged side by side in the Z-axis direction. The two C limit steel plate circular holes 3.3.4b of the C limit steel plate 3.3.4 are each connected to the B limit steel plate oblong holes 3.3.2b of the two B limit steel plates 3.3.2 via a C pin 3.3.3. This allows the C pin 3.3.3 to move along the length of the B limit steel plate oblong holes 3.3.2b, i.e., the X-axis direction, thereby allowing the C limit steel plate 3.3.4 and the B limit steel plate 3.3.2 to move relative to each other along the X-axis direction.

[0061] Two A-limiting steel plates 3.3.1 are arranged side by side in the X-axis direction. The circular holes 3.3.2a at each end of the B-limiting steel plate 3.3.2 are connected to the A-limiting steel plate oblong holes 3.3.1a of the A-limiting steel plate 3.3.1 via a C-pin 3.3.3. This allows the C-pin 3.3.3 to move along the length of the A-limiting steel plate oblong holes 3.3.1a, i.e., the X-axis direction, thereby allowing the A-limiting steel plates 3.3.1 and the B-limiting steel plates 3.3.2 to move relative to each other along the X-axis.

[0062] Furthermore, the size of the C-limiting steel plate square hole 3.3.4a is the same as that of the friction damper 3.5. Both ends of the friction damper 3.5 are adapted to extend outward through the C-limiting steel plate square hole 3.3.4a of the corresponding limiting assembly 3.3.

[0063] Furthermore, the limiting assembly 3.3 is welded to the support 3.1 via the limiting steel plate A 3.3.1. Specifically, the limiting steel plate A 3.3.1 is connected to the inner side of the support 3.1 via the outer side of the limiting steel plate A along the X-axis direction.

[0064] like Figure 10 and Figure 11 As shown, taking the Y-direction scissors-type deformation joint as an example, the scissors-type mechanism 3.6 includes two multi-link structures arranged alternately up and down along the Y-axis direction; the multi-link structure includes two short links 3.6.1 located at its two ends, and a plurality of long links 3.6.2 located between the two short links 3.6.1; the corresponding long links 3.6.2 in the two multi-link structures in the scissors-type mechanism 3.6 are arranged alternately up and down along the Y-axis direction; the short links 3.6.1 and the long links 3.6.2, as well as the long links 3.6.2 and the long links 3.6.2 of the same multi-link structure are connected to the oblong holes 3.1a of the corresponding supports 3.1 through the B pins 3.7; the ends of the short links 3.6.1 corresponding to the ends of the two multi-link structures are connected to the ends of the friction dampers 3.5 through the A pins 3.4.

[0065] The short connecting rod 3.6.1 includes a short connecting rod circular hole A 3.6.1a and a short connecting rod circular hole B 3.6.1b, which are used to connect the B pin 3.7 and the A pin 3.4 respectively; the long connecting rod 3.6.2 includes two long connecting rod circular holes 3.6.2a, both of which are used to connect the B pin 3.7.

[0066] In a specific implementation, the two multi-link structures are also suitable for forming a plurality of diamond-shaped telescopic structures arranged sequentially along the Y-axis. Accordingly, the spacing between the long link circular holes 3.6.2a is twice the spacing between the short link circular holes 3.6.1a and the short link circular holes 3.6.1b, so that the four sides of the diamond-shaped telescopic structure are equal in length, thereby forming a symmetrical structure.

[0067] In the embodiment of the present invention, the friction damper 3.5 is implemented by any known technical means in the prior art, which is not limited here.

[0068] like Figure 12 As shown, the support 3.1 of the scissor-type expansion joint 3 is connected to the floor 2.3 and the A floor 1.1.3 by screws 4. Specifically, the support web circular hole 3.1c of the support 3.1 is connected to the floor 2.3, the A floor 1.1.3, and the B floor 1.2.3 by screws 4.

[0069] The following combination Figures 13 to 15 The working principle of the energy dissipation and vibration reduction system based on the combination of modules and frames connected by scissor-type deformation joints is further introduced.

[0070] For example, the frame system 2 is relatively stationary, and the module unit system 1 produces a relative displacement in the positive X direction.

[0071] Under the action of an earthquake, when the relative distance between the two supports 3.1 in each of the first Y-direction scissors-type deformation joints 3.Y1 increases, the corresponding B pin 3.7 will move along the support oblong hole 3.1a, thereby causing relative rotation between the short link 3.6.1 and the long link 3.6.2 of the corresponding scissors-type mechanism 3.6, as well as between the long link 3.6.2 and the long link 3.6.2, thereby shortening the corresponding friction damper 3.5 connected to the scissors-type mechanism 3.6.

[0072] As the relative distance between the two supports 3.1 in the second Y-direction scissors-type deformation joint 3.Y2 decreases, the corresponding B pin 3.7 will move along the oblong hole 3.1a of the support, thereby causing relative rotation between the short link 3.6.1 and the long link 3.6.2 of the corresponding scissors-type mechanism 3.6, as well as between the long link 3.6.2 and the long link 3.6.2, thereby causing the corresponding friction damper 3.5 connected to the scissors-type mechanism 3.6 to extend.

[0073] Correspondingly, the relative distance between the two supports 3.1 of the first X-directional scissors-type deformation joint 3.X1 and the second X-directional scissors-type deformation joint 3.X2 remains unchanged, the friction dampers 3.5 of the first X-directional scissors-type deformation joint 3.X1 and the second X-directional scissors-type deformation joint 3.X2 remain relatively stationary, and the supports 3.1 of the first X-directional scissors-type deformation joint 3.X1 and the second X-directional scissors-type deformation joint 3.X2 slide horizontally along their respective support oblong holes 3.1a, causing the two supports 3.1 of the first X-directional scissors-type deformation joint 3.X1 and the second X-directional scissors-type deformation joint 3.X2 to respectively shift relative to each other, thereby releasing the forces exerted by the first X-directional scissors-type deformation joint 3.X1 and the second X-directional scissors-type deformation joint 3.X2 on the module unit system 1 and the frame system 2.

[0074] The scissor-type deformation joint 3 is defined as the restoring force provided by the module unit system 1 and the frame system 2. F d The initial spacing between the two supports 3.1 of the scissor-type expansion joint 3 is x d0 , the relative displacement of the scissor-type deformation joint 3 is x d , the design load of the friction damper 3.5 is F f , the relative displacement of the friction damper 3.5 is x f , the length of the short connecting rod 3.6.1 is l , the total number of diamond telescopic structures in each scissor mechanism 3.6 is n , the angle between the friction damper 3.5 and the short connecting rod 3.6.1 is θ .

[0075] Among them, the restoring force of the scissor-type deformation joint 3 F d , load of friction damper 3.5 F f The conversion relationship can be proved by the force balance condition; the relative displacement of the scissor-type deformation joint 3 is x d , the relative displacement of the friction damper 3.5 is x f The conversion relationship can be proved by the geometric relationship between the scissor mechanism 3.6 and the friction damper 3.5. The details are as follows:

[0076] like Figure 15 As shown, the 1 / 4 symmetrical structure of the diamond telescopic structure in the scissor mechanism 3.6 is taken as the basic analysis unit, and the formula (1) can be obtained according to the load conversion relationship diagram:

[0077] (1)

[0078] The initial length of the friction damper 3.5 in the static state is x f0 , the length of the friction damper 3.5 in the motion state is x f1 , then the relative displacement of the friction damper 3.5 x f The calculation formula is as follows:

[0079] (2)

[0080] exist Figure 15In the triangle ABC shown, the length of side AB is obtained by the Pythagorean theorem. The length of side AE ​​in rhombus ADEC is twice the length of side AB. Accordingly, the length of friction damper 3.5 is equal to the length of side AE. n times, thus formula (3) to formula (5) are obtained.

[0083] (5)

[0084] Based on the above, the combination of the first X-direction scissors-type deformation joint 3.X1, the second X-direction scissors-type deformation joint 3.X2, the first Y-direction scissors-type deformation joint 3.Y1, and the second Y-direction scissors-type deformation joint 3.Y2 can achieve bidirectional energy dissipation and vibration reduction by utilizing the relative displacement between the module unit system 1 and the frame system 2.

[0085] For example, consider a situation where the total number of diamond-shaped telescopic structures in scissor mechanism 3.6 is seven, the length of short link 3.6.1 is 300 mm, the initial spacing of scissor joints 3 is 300 mm, and the relative displacement of scissor joints 3 is 50 mm. When the design load of friction damper 3.5 is 50 kN, the restoring force provided by scissor joints 3 for module unit system 1 and frame system 2 can reach 251 kN, and the relative displacement of friction damper 3.5 can reach 226 mm.

[0086] This shows that by rationally configuring parameters such as the total number of diamond-shaped telescopic structures in the scissor mechanism 3.6, the length of the short connecting rod 3.6.1, and the initial spacing of the scissor-type deformation joints 3, the relative displacement between the modular unit system 1 and the frame system 2 can be amplified, thereby reducing the load demand on the friction damper 3.5.

[0087] Furthermore, compared to installing friction damper 3.5 directly on either side of modular unit system 1 and frame system 2, the concentrated load of friction damper 3.5 can be transferred to scissor mechanism 3.6 via pin A 3.4. Furthermore, because support 3.1 is much stiffer than scissor mechanism 3.6, support 3.1 can evenly transfer the concentrated load of pin B 3.7 on support oblong hole 3.1a to screw 4, converting the concentrated load of friction damper 3.5 into a uniformly distributed load, thereby preventing damage to the floor slab from concentrated forces. The scissor-type expansion joint 3 eliminates the need to drill holes in the floor slab during installation, nor does it require adjustment of the distance between modular unit system 1 and frame system 2, thus satisfying the space constraints imposed by the connection between modular unit system 1 and frame system 2.

[0088] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the scope defined by the claims.
