Description

Technical Field

[0001] This utility model belongs to the field of building structure technology, specifically relating to an embedded component for floor slab overlap. Background Technology

[0002] In the field of building structures, the connection nodes between floor slabs and columns are crucial for ensuring the overall structural stability and load transfer efficiency. Traditional connection methods often employ an indirect connection where beams are placed atop the columns, supported by floor slabs. This approach suffers from complex construction and low space utilization. With the development of industrialized building, modular prefabricated structural systems place higher demands on node connection technology, requiring both structural safety and rapid construction while optimizing space utilization.

[0003] In existing technologies, slab-column structural systems connect the floor slab directly to the column head, eliminating the need for beam components and effectively increasing the clear height of the space. This system often uses column cap reinforcement or pre-embedded connectors at the connection between the floor slab and column. However, in practical engineering applications, it still faces the following technical bottlenecks: traditional stud connectors require on-site welding, resulting in low construction efficiency and inconsistent quality; pre-embedded connectors have issues such as high positioning accuracy requirements and insufficient shear bearing capacity; under complex loads, stress concentration easily occurs in the joint area, leading to connector failure or floor slab cracking.

[0004] This utility model addresses the shortcomings of existing technologies by proposing a novel embedded component for floor slab overlap, which solves the problems of complex construction and insufficient shear resistance in traditional floor slab-column connection nodes. Utility Model Content

[0005] The purpose of this invention is to provide an insert for floor slab overlap in order to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an insert for floor slab overlap, comprising a column and an insert.

[0007] An installation groove is provided at the top of the column, and an anchoring steel bar is installed in the installation groove.

[0008] The insert is an I-shaped structure, including a lower flange, a web, and an upper flange;

[0009] The lower flange is fixed in the mounting groove and connected to the column by anchoring steel bars;

[0010] The web plate is vertically fixed to the center of the lower flange, and an insertion groove is provided on its side wall.

[0011] The upper flange has a mounting hole at its center that fits with the web clearance, and a square groove is formed on the end face near the web. The side wall of the square groove has an insertion groove two that corresponds to the position of the insertion groove one.

[0012] Four support plates are fixed to the upper flange sidewall. The support plates have notches and correspond to the shape of the upper flange sidewall. A gap is formed between adjacent support plates. The gap corresponds to the position of the second insertion slot.

[0013] Four fixing plates are fixed to the outer side of the top of the column, and rectangular telescopic blocks are slidably connected between adjacent fixing plates. The rectangular telescopic blocks are adapted to the support holes of the support plates to form a sealed chamber that encloses the column.

[0014] The present invention further describes that the insert also includes a connecting plate, which is snapped into the insertion groove one and the insertion groove two. Its lower part is in clearance fit with the insertion groove three of the sealing piston, and its upper part is in contact with the upper surface of the support plate.

[0015] The connecting plate has a snap-fit ​​groove, which snaps into the lower flange to achieve a tight connection between the fixed plate and the support plate.

[0016] The present invention further describes that an installation groove II and a sealing groove are provided in the lower flange, and the installation groove II is located on both sides of the web and communicates with the sealing groove;

[0017] The sealing piston is slidably connected in the second mounting groove. The bottom of the sealing piston is located in the sealing groove, and its end face is opened with the third insertion groove, which corresponds to the position of the first insertion groove.

[0018] A sliding groove is also provided in the lower flange, and a sliding plate is slidably connected in the sliding groove. The sliding plate is engaged with the connecting plate under the action of air pressure in the sealing groove.

[0019] The present invention further explains that the sealed chamber is composed of four fixed plates and four rectangular telescopic blocks. The rectangular telescopic blocks are located below the support holes and are adapted to them to prevent the upper flange from shifting or rotating.

[0020] The present invention further explains that the sealed chamber is composed of four fixed plates and four rectangular telescopic blocks. The rectangular telescopic blocks are located below the support holes and are adapted to them to prevent the upper flange from shifting or rotating.

[0021] The present invention further explains that the anchoring steel bar provided in the mounting groove is used to strengthen the connection strength between the embedded part and the column.

[0022] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: This utility model forms a three-dimensional force-bearing system through the coordinated action of the upper and lower flanges and the web of the I-shaped insert. The lower flange is anchored to the column top mounting groove, the web vertically transmits the load, and the upper flange is directly connected to the floor slab, which significantly enhances the shear bearing capacity of the joint.

[0023] The system employs a multi-path force transmission mechanism: "upper flange deformation coordination - horizontal force transmission through connecting plate - vertical load guidance through web". When the floor slab is under load, the upper flange transmits the horizontal component of the force to the ring frame through the embedding effect of the square groove and the support plate, while the vertical load is directly transmitted to the column through the web.

[0024] Through the coordinated constraint of the sealed chamber and the support hole, multiple seismic defense lines are formed: the ring frame composed of rectangular expansion blocks and fixed plates provides the first seismic barrier; the mechanical interlocking of the connecting plate and the snap-fit ​​groove constitutes the second fall protection; the air pressure damping effect of the sealing system absorbs seismic energy, thereby improving the energy dissipation capacity of the nodes.

A rectangular telescopic block 301 is slidably connected between two adjacent fixing plates 3. The rectangular telescopic block 301 is located below and adapted to the support hole 2041. The support hole 2041 is used to cooperate with the rectangular telescopic block 301 to achieve a stable connection of the structure and prevent the upper flange 203 from shifting or rotating.

[0038] The rectangular telescopic block 301 and the fixed plate 3 form a sealed chamber that encloses the column 1.

[0039] Each sidewall of the web plate 202 is provided with an insertion slot 1 2021, and the insertion slot 20321 corresponds to the insertion slot 1 2021.

The two sliding grooves 209 are located directly below the insertion groove 2021. A sliding plate 210 is slidably connected in the sliding groove 209. The sliding plate 210 is used to engage the connecting plate 205.

[0042] Working principle:

[0043] Installation of insert 2: Fix the lower flange 201 into the mounting groove 101 at the top of the column 1, and strengthen the connection by anchoring steel bars.

[0044] A web plate 202 is fixed above the lower flange 201, a connecting plate 205 is placed on the lower flange 201, and one end of the connecting plate 205 with a snap-fit ​​groove 2051 is inserted into the insertion groove 2021.

[0045] Install the upper flange 203 onto the web plate 202 through the mounting hole 2031 and adjust it to a suitable position to ensure that the square groove 2032 and the support hole 2041 are in accurate position. At this time, the insertion groove 20321 on the upper flange 203 is in clearance fit with the connecting plate 205.

[0046] During the installation of the upper flange 203 and the web plate 202, the distance between the upper flange 203 and the lower flange 201 gradually decreases. The upper flange 203 first contacts the sealing piston 208, and the upper flange 203 drives the sealing piston 208 to move downward. The air pressure in the sealing groove 207 gradually increases. Under the action of the air pressure in the sealing groove 207, the sliding plate 210 moves upward and enters the interior of the snap-fit ​​groove 2051 to snap the connecting plate 205, thereby fixing the upper flange 203.

[0047] Formation of the sealed chamber: Four fixed plates 3 are fixed along the outer diameter of the column 1, and rectangular telescopic blocks 301 are slidably connected to form a sealed chamber with the fixed plates 3, which encloses the column 1, while ensuring that the rectangular telescopic blocks 301 are adapted to the support holes 2041.

[0048] When the floor slab is under load, the initial stress dispersion is achieved through the deformation coordination of the upper flange 203. The connecting plate 205 transfers the horizontal component of the force to the annular frame formed by the fixed plate 3. The vertical load is transferred to the lower flange 201 through the web 202, and finally introduced into the column through the anchoring steel bars. During the load transfer process, the cooperation between the rectangular expansion block 301 and the support hole 2041 always maintains the structural alignment, and the displacement compensation mechanism of the sealing piston 208 ensures that the connection interface can maintain its sealing performance under deformation conditions.
