Description

Technical Field

[0001] The present invention relates to the technical field of building systems, and in particular to a restorable functional floor system and a building. Background Art

[0002] With today's ever-increasing construction needs, floor systems, as an integral component of building structures, have a direct impact on their overall safety, affordability, and comfort. Recoverable floor systems, a traditional floor construction method, have been widely adopted in various types of buildings due to their simple structure and ease of construction. However, with the continuous advancement of construction technology and increasing demands for building performance, these systems have also exposed certain problems and challenges in their structural design and application.

[0003] Resilient floor systems typically rely on columns as the primary vertical load-bearing components. Floor loads are transferred to the columns via horizontal components such as beams and slabs, and the columns then transmit the loads to the foundation. This structural form is particularly common in multi-story and high-rise buildings. Its design principle is based on force balance and transmission, effectively supporting floor loads and ensuring the overall stability of the building. Summary of the Invention

[0004] The object of the present invention is to provide a restorable functional floor system to solve at least one technical problem existing in the prior art.

[0005] In order to solve the above technical problems, the present invention provides a restorable functional floor system, comprising a floor, a steel beam, a column transmission device and a column;

[0006] The floor is arranged on the steel beam;

[0007] The column transfer device is an elastic structure and is arranged between the steel beam and the column;

[0008] When relative movement occurs between the floor slab and the column, the column transfer device can play an energy dissipation role.

[0009] Furthermore, the column transmission device includes a compression spring and a core column;

[0010] The end of the steel beam is provided with a force transmission plate;

[0011] One end of the core column is fixedly arranged on the force transmission plate, and the other end is a free end;

[0013] Furthermore, a reinforcement sleeve is provided on the column;

[0014] The compression spring abuts against the reinforcement sleeve.

[0015] Furthermore, the floor is arranged on the steel beam;

[0016] The steel beam comprises a pentagonal perforated stiffener, a support plate and prestressed steel strands;

[0019] Furthermore, an L-shaped perforated stiffening plate passing through the prestressed steel strand is provided between the pair of pentagonal perforated stiffening plates;

[0020] The lower end of the support plate abuts against the L-shaped perforated stiffening plate.

[0021] Furthermore, a rubber support is provided on the support plate;

[0022] The rubber bearing includes a supporting portion, a first connecting portion and a second connecting portion;

[0023] The support portion is a column made of rubber;

[0034] By adopting the above technical solution, the present invention has the following beneficial effects:

[0035] (1) By introducing the column transmission device as an elastic structure, the relative slip between the steel beam and the column will be effectively absorbed by the compression spring of the column transmission device during earthquakes or other external stress disturbances, thereby dissipating the seismic energy, reducing the damage to the structure, and significantly improving the seismic performance of the floor system.

[0036] (2) The design of the column transfer device enables the floor system to stabilize the structure through the compression deformation of the spring when subjected to external forces, thereby preventing the structure from becoming unstable or damaged due to external forces.

[0037] (3) The construction of the restorable functional floor system is divided into two stages: factory processing and on-site installation.

[0063] The present invention will be further explained below with reference to specific embodiments.

[0064] Example 1

[0065] like Figure 1 and 10 As shown, this embodiment provides a restorable functional floor system, including a floor, a steel beam 1, a column transmission device 2 and a column 3;

[0066] The floor is arranged on the steel beam 1;

[0067] The column transfer device 2 is an elastic structure and is arranged between the steel beam 1 and the column 3;

[0068] When relative movement occurs between the floor slab and the column 3, the column transfer device 2 can dissipate energy.

[0069] The column transmission device 2 includes a compression spring 4 and a core column 5;

[0070] The end of the steel beam 1 is provided with a force transmission plate 18;

[0071] One end of the core column 5 is fixed on the force transmission plate 18, and the other end is a free end;

[0072] The compression spring 4 is wound on the core column 5 , with one end of the compression spring 4 being fixed on the core column 5 and the other end of the compression spring 4 being directly or indirectly in contact with the column 3 .

[0073] The column 3 is provided with a reinforcing sleeve 6;

[0074] The compression spring 4 abuts against the reinforcement sleeve 6 .

[0075] When the resilient functional floor system of the present application encounters an earthquake or other external stress disturbance, relative slippage will occur between the steel beam 1 and the column 3. To dissipate the energy of the steel beam 1 and the column 3 and prevent damage, the compression spring 4 of the column transfer device 2 will be compressed along the axial direction of the core column 5, thereby dissipating energy.

[0076] Example 2

[0077] like Figure 1-9 The second embodiment of the present application is shown, in which the floor is arranged on the steel beam 1;

[0078] The steel beam 1 comprises a pentagonal perforated stiffening plate 7, a support plate 8 and prestressed steel strands 9;

[0079] The pentagonal perforated stiffening plate 7 is passed through the prestressed steel strand 9;

[0080] The pentagonal perforated stiffening plates 7 are arranged in pairs, and a supporting plate 8 is arranged between the pair of pentagonal perforated stiffening plates 7 .

[0081] An L-shaped perforated stiffening plate 10 passing through the prestressed steel strand 9 is further provided between the pair of pentagonal perforated stiffening plates 7;

[0082] The lower end of the support plate 8 abuts against the L-shaped perforated stiffening plate 10 .

[0083] The support plate 8 is provided with a rubber support 11;

[0084] The rubber support 11 includes a supporting portion 12, a first connecting portion 13 and a second connecting portion 14;

[0085] The support portion 12 is a column 3 made of rubber;

[0086] The first connecting portion 13 and the second connecting portion 14 are fixedly connected at both ends of the support portion 12;

[0087] The first connecting portion 13 is fixedly connected to the supporting plate 8 .

[0088] The second connecting portion 14 is provided with a connecting plate 15;

[0089] The connecting plate 15 is connected to the second connecting portion 14 via fasteners.

[0090] The end of the connecting plate 15 away from the rubber support 11 is provided with a bolt 16;

[0093] The post-cast concrete 17 is arranged on the connecting plate 15;

[0094] The studs 16 are embedded in the post-cast concrete 17 .

[0095] The construction of the reusable functional floor system of this application includes two stages: factory processing and on-site installation. During the factory processing stage, holes are pre-drilled, the short beams and columns 3 are welded together to form a whole, reinforcement sleeves 6 are welded to the outside of the steel columns, force transfer plates 18 are welded to the steel beams 1, core columns 5 are welded to the force transfer plates 18, and compression springs 4 are installed on the core columns 5.

[0096] During the on-site installation phase, the columns 3 are first positioned and installed, and the beams are hoisted in place using a crane. Prestressed steel strands 9 are threaded through the beams and prestressed, and the beams are connected using high-strength bolts. The rubber bearings 11 are then fastened to the beams using high-strength bolts.

[0097] (1) By introducing the column transmission device 2 as an elastic structure, the relative slip between the steel beam 1 and the column 3 during an earthquake or other external stress disturbance will be effectively absorbed by the compression spring 4 of the column transmission device 2, thereby dissipating the seismic energy, reducing the damage to the structure, and significantly improving the seismic performance of the floor system.

[0098] (2) The design of the column transfer device 2 enables the floor system to stabilize the structure through the compression deformation of the spring when subjected to external force, thereby preventing the structure from becoming unstable or being damaged due to external force.

[0099] (3) The construction of the restorable functional floor system is divided into two stages: factory processing and on-site installation. This prefabricated and assembled construction method effectively shortens the construction period, improves construction efficiency, and reduces safety risks at the construction site.

[0100] (4) The use of components such as rubber bearings 11 not only provides a good seismic isolation effect, but also enhances the durability and service life of the structure. The elastic properties of the rubber bearings 11 enable the floor system to maintain good stability and comfort during long-term use.

[0101] (5) By introducing structural reinforcement measures such as pentagonal perforated stiffeners 7 and L-shaped perforated stiffeners 10, the bearing capacity of the steel beam 1 is effectively improved, enabling the floor system to withstand greater loads and increasing the safety of the structure.

[0102] (6) The components such as the column transfer device 2 and the rubber support 11 are all modularly designed, which are easy to maintain and replace, reducing the subsequent maintenance costs and improving the ease of use of the structure.

[0123] In this embodiment, the outer end of the transverse beam positioning barrel 250 is designed to be an "eight"-shaped outer shell body, and the outer wing frame 650 extends toward the longitudinal beam positioning frames 210 on the upper and lower sides, and a connecting frame surface 710 is provided on the outer shell body of the outer barrel connecting bolt 240, and the adjustment block 740 is installed on the adjustment groove 720, and the operating position of the fine-tuning connection adjustment block 740 is used to make the parallel bolt 730 accurately inserted into the locking bolt 560, and then the parallel bolt 730 is locked and fixed by the locking bolt 550, and at the same time, the fixing bolts on the locking connection adjustment block 740 are used to complete the fixed installation of the outer wing frame 650 and the longitudinal beam positioning frames 210 of the upper and lower wings.

[0124] In this way, on the basis of the main connecting vertical support frame 120 as the connecting structure of the transverse steel beams and the longitudinal steel beams, the transverse beam positioning barrel 250 and the longitudinal beam positioning frame 210 used to fix the transverse steel beams and the longitudinal steel beams are connected, thereby improving the stability coefficient of the overall connecting area. Even in the structure of multiple staggered steel beams, sufficient stability can be guaranteed to ensure the support strength of the overall building structure.

[0125] Compared with the prior art, the present invention has the following beneficial effects:

[0126] (1) The present invention is used for positioning and connecting multiple steel beams at staggered positions. The main connecting transverse support frame and the main connecting vertical support frame are the main supporting structures. The barrel connecting piece is fixed on the transverse steel beam, and the longitudinal steel beam staggered with the transverse steel beam is fixed and positioned by the longitudinal beam positioning frame; an opening is provided at the center line position of the main connecting vertical support frame, and a transverse positioning sleeve is provided at the opening. The main body of the barrel connecting piece is a transverse beam positioning barrel, and the transverse beam positioning barrel is stably fixed in the transverse positioning sleeve by an outer tube hoop, thereby ensuring the reliability of the fixing structure itself; the transverse steel beam is integrally installed in the transverse beam positioning barrel on the left and right sides, and the longitudinal steel beams erected above and below the transverse steel beam are internally positioned in the longitudinal beam positioning frame.

[0127] (2) The present invention also provides an adjustment outer frame on the upper and lower sides of the transverse positioning sleeve for slightly adjusting the working position of the external support connector, that is, adjusting the working position of the longitudinal beam positioning frame for positioning the longitudinal steel beam. After the adjustment is completed, the external support connector is locked and fixed on the adjustment outer frame, thereby adapting to the coordinate differences of the longitudinal steel beam and the transverse steel beam in different building areas.

[0128] (3) The present invention is also provided with an outer cylinder connecting bolt and an outer frame connecting bolt, and the longitudinal beam positioning frame and the barrel connecting piece are connected again by the outer cylinder connecting bolt and the outer frame connecting bolt, thereby adding the connection point between the transverse steel beam and the longitudinal steel beam on the outside of the main connecting vertical support frame, thereby improving the overall stability coefficient.

[0129] The present invention can effectively ensure the staggered installation of multiple groups of longitudinal steel beams and transverse steel beams, and set a stable frame connection structure at the staggered installation position to form a stable support from the inside to the outside, thereby forming an integral and stable connection interval.
