Description

Technical Field

[0001] This invention belongs to the field of seismic resistance technology for public buildings, specifically a BIM-based seismic-resistant composite beam for public buildings and its construction method. Background Art

[0002] BIM uses various relevant information and data of a building project as the basis for building model creation, and simulates the real information of the building through digital information.

[0003] Earthquake resistance of public buildings refers to the building's ability to effectively resist seismic forces during an earthquake, reducing structural damage and casualties. To improve a building's seismic performance, appropriate materials, structural design, and technical measures must be considered during design and construction to ensure the building's safe and stable operation during an earthquake. Based on BIM (Building Information Modeling), structural designers can comprehensively consider multiple factors such as material properties, component dimensions and shapes, and connection methods to ensure the structure has sufficient strength and stability during earthquakes.

[0020] A construction method for seismic-resistant composite beams in public buildings based on BIM includes the following steps:

[0021] Step 1: Preliminary Preparations

[0022] Prepare the necessary materials, including shock absorber 202, support plate 201, first support column 101, second support column 103, limiter 102, bolts, and anti-tipping assembly 300; check the quality of all materials to ensure there is no damage or defect, and perform pretreatment as needed, such as cleaning and rust prevention;

[0023] Step 2: Install shock absorbers and support plates:

[0024] Fix the shock absorber 202 to the middle position of the support plate 201, ensuring that it is firmly fixed and without loosening; insert the shock absorber 202 and the support plate 201 into the middle position of the first support member 101 and the second support member 103, ensuring that the insertion is stable and without shaking.

[0025] Step 3: Install the limiting components:

[0026] Several limiting members 102 are fixed to the first support member 101 with bolts to ensure that the bolts are tightened and the limiting members are stable; several limiting members 102 are connected to each other in sequence with bolts to form a stable limiting system, so that the second support member 103 is effectively limited.

[0027] Step 4: Install the anti-tipping components:

[0028] Check the verticality of the first support member 101 and the second support member 103. If there is any tilting, adjust it in time. Install the anti-tipping component 300 in an appropriate position to ensure that it provides effective support for the second support member 103.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] This invention uses a first support plate and a second support plate to fix the rigid spacer block and rubber pad, which are then installed between the first and second support pillars. This provides additional axial damping to the first and second support pillars, reducing the vertical seismic response or vertical environmental vibration response of the structure. When the connection between the second and first support pillars tilts severely during vibration, the support arm and support block can provide support, while the paint-coated part of the warning pole is exposed to alert personnel.

Detailed Implementation

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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 are within the scope of protection of the present invention.

[0040] See also Figure 1-5This invention provides a BIM-based seismic composite beam for public buildings, comprising a frame assembly 100, including a first support member 101, a limiting member 102 located on the first support member 101, and a second support member 103 connected to the limiting member 102; a damping assembly 200, including a support plate 201 located within the limiting member 102, and a damping member 202 located in the middle of the support plate 201; and an anti-tipping assembly 300, including a first support member connector 301 located outside the first support member 101, and a second support member connector 302 located outside the second support member 103. The damping component 202 is fixed to the middle position of the support plate 201. The damping component 202 and the support plate 201 are then snapped into the middle position of the first support member 101 and the second support member 103. Several limiting components 102 are fixed to the first support member 101 with bolts. At the same time, several limiting components 102 are connected to each other in sequence with bolts, thereby limiting the second support member 103. The damping component 202 and the support plate 201 can provide additional axial damping for the first support member 101 and the second support member 103 to reduce the vertical seismic response or vertical environmental excitation response of the structure. If the first support member 101 and the second support member 103 tilt, the anti-tipping component 300 can provide a certain support for the second support member 103.

[0041] Specifically, the first support member 101 includes a first support body 101a, on which a first support fixing plate 101a-1 is provided; the limiting member 102 includes a shear rib 102a, on which a first connecting plate 102a-1 is provided; the first connecting plate 102a-1 is fixed to the first support fixing plate 101a-1 by bolts, and the connection between the first support fixing plate 101a-1 and the first support body 101a is reinforced by pre-welded stiffening ribs, thereby enhancing local stiffness.

[0042] Specifically, the second support member 103 includes a second support body 103a, on which a second support fixing plate 103a-1 is provided; a second connecting plate 102a-2 is also provided on the shear rib 102a; the second support body 103a is limited by a number of second connecting plates 102a-2, and the number of second connecting plates 102a-2 are fixedly connected by bolts. The number of adjacent second connecting plates 102a-2 are fixedly connected by bolts in sequence. The connected number of second connecting plates 102a-2 can just restrain the second support body 103a so that the second support body 103a can only move up and down.

[0043] Specifically, the support plate 201 includes a first support plate 201a and a second support plate 201b; the damping component 202 includes a plurality of rigid spacer blocks 202a and rubber pads 202b; the rigid spacer blocks 202a and rubber pads 202b are indirectly disposed in the middle position of the first support plate 201a and the second support plate 201b, and the rubber pads 202b are made of thick rubber with a small shape factor, that is, the ratio of the constrained area to the free surface area is small, so as to provide sufficient vertical flexibility and additional damping.

[0044] Specifically, the first support plate 201a and the second pillar fixing plate 103a-1 are fixedly connected by bolts, and the second support plate 201b and the first pillar fixing plate 101a-1 are fixedly connected by bolts.

[0045] As can be seen from the above, the rigid spacer 202a and the rubber pad 202b are indirectly set in the middle position of the first support plate 201a and the second support plate 201b. The first support plate 201a and the second pillar fixing plate 103a-1 are then fixedly connected by bolts. The second support plate 201b and the first pillar fixing plate 101a-1 are also fixedly connected by bolts. Several first connecting plates 102a-1 are fixed to the first pillar fixing plate 101a-1 by bolts. A thin layer of lubricating oil is pre-applied to the position of several second connecting plates 102a-2 near the second pillar body 103a. Then, several adjacent second connecting plates 102a-2 are sequentially fixedly connected by bolts.

[0046] The first support connector 301 includes a first support connector body 301a, which is fixedly connected to the first support member 101; wherein, the first support connector body 301a has a through hole that matches the reinforcing threaded rod 303a, thereby limiting the reinforcing threaded rod 303a.

[0047] Specifically, the second support connector 302 includes a second support connector body 302a, which is fixedly connected to the second support member 103; wherein, the second support connector body 302a has a through hole that matches the reinforcing threaded rod 303a, thereby limiting the reinforcing threaded rod 303a.

[0048] Specifically, the anti-tipping component 300 also includes a number of reinforcing rods 303 located between the first pillar connector 301 and the second pillar connector 302, which can strengthen the support capacity between the second pillar body 103a and the first pillar body 101a.

[0049] Specifically, the reinforcing rod 303 includes a reinforcing threaded rod 303a, with a frustum 303a-1 on the outer side of the reinforcing threaded rod 303a and several nuts 303a-2 on the outer side of the reinforcing threaded rod 303a; wherein, when the reinforcing threaded rod 303a is fixed to the first support connector body 301a and the second support connector body 302a, the frustum 303a-1 on the reinforcing threaded rod 303a is partially embedded in the upper side of the first support connector body 301a.

[0050] Specifically, the outer side of the first pillar connector body 301a is provided with several support arms 301a-1, and support blocks 301a-2 are provided on the support arms 301a-1; the outer side of the second pillar connector body 302a is provided with several warning rods 302a-1; the support arms 301a-1 are also provided with movable holes 301a-3, and the warning rods 302a-1 can move freely within the movable holes 301a-3. The part of the warning rods 302a-1 located within the movable holes 301a-3 is coated with paint; among them, several support arms 301a-1 are snap-fit ​​shaped, and the movable holes 301a-3 located on the support arms 301a-1 are elliptical, and the warning rods 302a-1 can move flexibly up, down, left, and right within the movable holes 301a-3.

[0051] As can be seen from the above, the reinforcing threaded rod 303a is fixed to the first support connector body 301a and the second support connector body 302a by a number of nuts 303a-2. The frustum column 303a-1 abuts against the first support connector body 301a. When the second support body 103a and the first support body 101a are relatively offset, the second support connector body 302a located on the second support body 103a will also be offset. At this time, the reinforcing threaded rod 303a and the frustum column 303a-1 can play the role of strengthening support and assisting connection. When the connection between the second support body 103a and the first support body 101a tilts severely during vibration, the reinforcing threaded rod 303a and the second support connector body 302a both move along the tilt direction of the second support body 103a, while the first support connector body 301a outside the second support body 103a does not move. When the second support connector body 302a moves and abuts against the support arm 301a-1, the support arm 301a-1 and the support block 301a-2 can provide support, and at the same time, the part of the warning rod 302a-1 with paint is exposed to remind personnel.

[0058] Several limiting members 102 are fixed to the first support member 101 with bolts to ensure that the bolts are tightened and the limiting members are stable; several limiting members 102 are connected to each other in sequence with bolts to form a stable limiting system, so that the second support member 103 is effectively limited.
