Description

Technical Field

[0001] This invention relates to the field of prefabricated beam socket filling technology, specifically to prefabricated beam socket filling structures, filling methods, and building structures. Background Technology

[0002] With the rapid development of prefabricated buildings in my country, more and more structural forms have emerged, and prefabricated steel structure systems have come into being as a new type of building structure system. H-beams are commonly used components in steel structure systems. One application of H-beams is for connection and fit with walls. To ensure that the H-beams can be aligned with the wall surface and to consider the requirements for thermal insulation and sound insulation of the steel beams, the recesses on both sides of the steel beams need to be filled.

[0003] Currently, hollow bricks are commonly used to fill beam sockets, with cement slurry applied to the outer surface of the hollow bricks. However, this method requires the construction of multiple hollow bricks, resulting in low construction efficiency. Furthermore, the large weight of hollow bricks can easily cause excessive downward deformation of the steel beams. Moreover, hollow brick filling cannot provide good sound insulation and fireproofing effects. Therefore, the hollow brick filling method has significant drawbacks. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a prefabricated beam socket filling structure, filling method, and building structure. This technical solution solves the problems mentioned in the background art, where hollow bricks are commonly used for filling beam sockets, with cement slurry applied to the outer surface of the hollow bricks. However, this filling method requires the construction of multiple hollow bricks, resulting in low construction efficiency. Furthermore, the significant weight of hollow bricks can easily cause excessive downward deformation of the steel beams. Moreover, hollow brick filling cannot provide adequate sound insulation and fireproofing. Therefore, the hollow brick filling method has significant drawbacks.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A prefabricated beam-socket filling structure includes a steel beam, which is I-shaped. Beam sockets are formed on both sides of the steel beam. Rock wool boards are filled into both beam sockets near the web of the steel beam. Vertically arranged sound insulation boards are spaced apart on the outer side of the rock wool boards. A cavity sound insulation layer is formed between the rock wool boards and the sound insulation boards. Several sets of fixing components for fixing the upper and lower ends of the sound insulation boards are provided at the inner top and bottom of each beam socket. A fireproof layer located outside the sound insulation boards is filled into each beam socket. Prefabricated filling blocks located outside the fireproof layer are also filled into each beam socket. Installation components are attached to the outer side of each prefabricated filling block. The upper and lower sides of the installation components are connected to the inner top and inner bottom of the beam socket, respectively. Wall panel components are installed on the outer side of the installation components.

[0006] Preferably, the upper and lower ends of the sound insulation board are respectively attached to the inner top and inner bottom of the beam socket, and the outer sides of the upper and lower ends of the sound insulation board are provided with reserved grooves, which are filled with high-density polyurethane foam.

[0007] Preferably, the sound insulation board is a double-layer gypsum board, which is composed of two single-layer gypsum boards combined together. The thickness of one single-layer gypsum board is 12mm, and the thickness of the rock wool board is ≥50mm.

[0008] Preferably, the fixing component includes two L-shaped angle steels arranged symmetrically at intervals, the sound insulation plate is sandwiched between the vertical plates of the two L-shaped angle steels, and a vertically arranged fixing screw is passed through the horizontal plate of the L-shaped angle steel. One end of the fixing screw passes through the horizontal plate of the L-shaped angle steel and is threadedly connected to the steel beam.

[0009] Preferably, the precast filling block is made of lightweight aggregate concrete, and a water-swellable rubber strip is provided on the contact surface between the precast filling block and the beam socket.

[0010] Preferably, the installation assembly includes a vertically arranged support plate, with square installation tubes integrally formed at both the upper and lower ends of the support plate. The support plate is fitted to the precast filling block, and the upper and lower square installation tubes are fitted to the inner top and inner bottom of the beam socket, respectively. A first self-tapping screw, which is vertically arranged, and a second self-tapping screw, which is horizontally arranged, are passed through the upper and lower square installation tubes. The first self-tapping screw passes through the square installation tube and is then inserted into the steel beam. The second self-tapping screw passes through the wall panel assembly and the square installation tube in sequence, and is finally inserted into the steel beam.

[0011] Preferably, the wall panel assembly includes a first wall panel and a second wall panel arranged inside and outside each other. One side of the first wall panel is fitted with the square mounting tube, and the outer side of the first wall panel is flush with the outer end of the beam socket. The second wall panel is fitted with the first wall panel, and the second self-tapping screw passes through the second wall panel, the first wall panel, and the square mounting tube in sequence, and finally passes through the precast filling block.

[0012] The building structure includes walls and floors. The steel beams are supported between the walls and floors. The outer side of the second wall panel is flush with the sidewall of the wall. The outer side of the second wall panel and the sidewall of the wall are covered with wire mesh and coated with an outer coating.

[0013] Preferably, the bottom of the steel beam is filled with polymer mortar containing an elastic modifier between it and the wall, which forms a flexible buffer layer after curing.

[0014] The method for filling sockets in prefabricated beams includes the following steps: S1. Before filling, first remove debris and dust from the beam socket and rinse it with a high-pressure water gun. Then apply anti-rust paint to the beam socket. After the anti-rust paint dries, the filling work can be carried out. S2. When filling, first fill the beam sockets on both sides of the steel beam with rock wool boards, and then install the sound insulation board. When installing the sound insulation board, a cavity sound insulation layer needs to be left between the sound insulation board and the rock wool board. Then, first install the inner L-shaped angle steel into the inner top and inner bottom of the beam socket with fixing screws. When installing the inner L-shaped angle steel, the vertical plate of the L-shaped angle steel needs to be set outward. Then fill the beam socket with the sound insulation board, so that one side of the sound insulation board is attached to the outside of the vertical plate of the L-shaped angle steel. Then install the outer L-shaped angle steel into the inner top and inner bottom of the beam socket with fixing screws, so that the sound insulation board is sandwiched between the vertical plates of the left and right L-shaped angle steel. S3. Then fill the beam socket with a fireproof layer and precast filling blocks. The fireproof layer is filled between the outer L-shaped angle steel and the precast filling blocks. When filling the precast filling blocks, water-swellable rubber strips are installed in the gap between the precast filling blocks and the beam socket. Then, the upper and lower square mounting tubes are fixedly installed on the inner top and inner bottom of the beam socket by the first self-tapping screws on the upper and lower sides. At the same time, the support plate will be fitted with the precast filling blocks to fix and strengthen the precast filling blocks. S4. Finally, attach the first wall panel to the outside of the two square mounting tubes, then attach the second wall panel to the outside of the first wall panel, then pass the second self-tapping screw through the second wall panel, the first wall panel and the square mounting tube in sequence, and finally pass it through the precast filling block. Then, attach a mesh and plaster to the outside of the second wall panel and the side wall of the wall as a whole to complete the filling.

[0015] Compared with the prior art, the present invention provides a prefabricated beam socket filling structure, filling method and building structure, which has the following beneficial effects: 1. This invention fills the beam sockets with precast lightweight aggregate concrete blocks. The dry density of lightweight aggregate concrete is 1 / 5 that of ordinary concrete, which greatly reduces the self-weight of the structure, reduces foundation costs, facilitates handling and installation, and avoids excessive pressure on the steel beams, resulting in excessive deflection deformation. At the same time, the precast filling blocks can be standardized in the factory and directly assembled into the beam sockets, which can be directly assembled during construction, which helps to speed up construction efficiency and save on-site assembly time and labor costs.

[0016] 2. This invention utilizes a combination of rock wool boards, sound insulation boards, a cavity sound insulation layer, and a fireproof layer. By filling the beam cavity with rock wool boards and sound insulation boards, and setting up a cavity sound insulation layer, sound transmission can be effectively blocked, thus achieving a sound insulation effect. The fireproof layer and the precast filling blocks made of lightweight aggregate concrete are both made of Class A fireproof materials, which can effectively prevent the spread of flames. Their non-combustible properties increase the fire delay time by more than 50%, thereby achieving the purpose of isolating the fire source and preventing the rapid spread of fire.

Detailed Implementation

[0019] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0020] Example 1 Please refer to Figures 1 to 2As shown, the prefabricated beam-socket filling structure includes a steel beam 1, which is arranged in an I-shape. Beam sockets 2 are formed on both sides of the steel beam 1. Rock wool boards 3 are filled in the two beam sockets 2 near the web of the steel beam 1. The porous fiber structure of the rock wool board 3 can absorb medium and high frequency sound waves and reduce noise transmission. At the same time, the rock wool board 3 is made of natural minerals such as basalt and has a fire resistance rating of A1, which can also effectively prevent the spread of fire. The rock wool board 3 is provided with vertically arranged sound insulation boards 4 at intervals on its outer side. A cavity sound insulation layer is formed between the rock wool board 3 and the sound insulation board 4. The inner top and inner bottom of the beam socket 2 are provided with several sets of fixing components 5 for fixing the upper and lower ends of the sound insulation board 4. The beam socket 2 is filled with a fireproof layer 6 located outside the sound insulation board 4. The beam socket 2 is also filled with a prefabricated filling block 7 located outside the fireproof layer 6. An installation component 8 is attached to the outer side of the prefabricated filling block 7. The upper and lower sides of the installation component 8 are connected to the inner top and inner bottom of the beam socket 2, respectively. A wall panel component 9 is installed on the outer side of the installation component 8.

[0021] Those skilled in the art will understand that the prefabricated filling block 7 in this invention can be directly assembled into the beam socket 2 after being standardized in the factory. It can be directly assembled during construction, which helps to speed up construction efficiency and save on-site assembly time and labor costs.

[0022] In addition, filling the beam cavity 2 with rock wool board 3 and sound insulation board 4, and setting a cavity sound insulation layer, can effectively block the transmission of sound, thereby achieving a sound insulation effect. The fireproof layer 6 and the precast filling block 7 made of lightweight aggregate concrete are both made of Class A fireproof materials, which can effectively prevent the spread of flames. Their non-combustible properties increase the fire delay time by more than 50%, thereby achieving the purpose of isolating the fire source and preventing the rapid spread of fire.

[0023] Example 2 Furthermore, the upper and lower ends of the sound insulation board 4 are respectively attached to the inner top and inner bottom of the beam socket 2, and the outer sides of the upper and lower ends of the sound insulation board 4 are provided with reserved grooves 10, which are filled with high-density polyurethane foam.

[0024] Those skilled in the art will understand that the reserved groove 10 provided in this invention facilitates the filling of high-density polyurethane foam. By filling the upper and lower reserved grooves 10 with high-density polyurethane foam, the gap between the upper and lower ends of the sound insulation board 4 and the inner top and inner bottom of the beam socket 2 can be filled and sealed, thereby optimizing the sound insulation effect.

[0025] In addition, a special reserved groove 10 is provided for filling with high-density polyurethane foam, which can reserve space for the expansion of high-density polyurethane foam and avoid the expansion of high-density polyurethane foam affecting the installation of external L-shaped angle steel 501.

[0026] Example 3 Furthermore, the sound insulation board 4 is a double-layer gypsum board, which is composed of two single-layer gypsum boards combined together. The thickness of one single-layer gypsum board is 12mm, and the thickness of the rock wool board 3 is ≥50mm.

[0027] Those skilled in the art will understand that the double-layer gypsum board in this invention can reduce sound transmission by 30%-50%, and when combined with the cavity sound insulation layer and rock wool board 3 to form a sound insulation structure, it can isolate sound transmission.

[0028] Example 4 Furthermore, the fixing component 5 includes two L-shaped angle steels 501 arranged symmetrically at intervals, the sound insulation plate 4 is sandwiched between the vertical plates of the two L-shaped angle steels 501, and a vertically arranged fixing screw 502 is passed through the horizontal plate of the L-shaped angle steels 501. One end of the fixing screw 502 passes through the horizontal plate of the L-shaped angle steels 501 and is threadedly connected to the steel beam 1.

[0029] Those skilled in the art will understand that, in this invention, when installing the sound insulation panel 4, the inner L-shaped angle steel 501 is first installed in the inner top and inner bottom of the beam socket 2 using fixing screws 502. When installing the inner L-shaped angle steel 501, the vertical plate of the L-shaped angle steel 501 needs to be set outwards. Then, the sound insulation panel 4 is filled into the beam socket 2, so that one side of the sound insulation panel 4 is attached to the outer side of the vertical plate of the L-shaped angle steel 501. Then, the outer L-shaped angle steel 501 is installed in the inner top and inner bottom of the beam socket 2 using fixing screws 502, while the vertical plate of the outer L-shaped angle steel 501 is attached to the outer side of the sound insulation panel 4, so that the sound insulation panel 4 is clamped and fixed between the vertical plates of the left and right L-shaped angle steel 501.

[0030] Example 5 Furthermore, the precast filling block 7 is made of lightweight aggregate concrete, and a water-swellable rubber strip 11 is provided on the contact surface between the precast filling block 7 and the beam socket 2.

[0031] Those skilled in the art will understand that the precast filler block 7 made of lightweight aggregate concrete used in this invention has a dry density of only 400-700 kg / m³, which is 1 / 5 of that of ordinary concrete. This significantly reduces the self-weight of the structure, reduces the cost of the foundation, facilitates handling and installation, and avoids excessive pressure on the steel beam 1, resulting in excessive downward deformation.

[0032] In addition, its lightweight properties reduce seismic inertial forces, and combined with the energy absorption capacity of inorganic aggregates, the seismic performance is improved by more than 30%, and it meets the Class A fire protection standard with a fire resistance limit of more than 2 hours. It is also recyclable, reducing construction waste pollution.

[0033] A water-swellable rubber strip 11 is installed on the contact surface between the precast filling block 7 and the beam socket 2. When the water-swellable rubber strip 11 comes into contact with water, it expands in volume and can tightly fill the gaps in the contact surface, effectively blocking the water penetration path and preventing rainwater from seeping into the interior of the structure.

[0034] Example 6 Furthermore, the installation assembly 8 includes a vertically arranged support plate 801. Both the upper and lower ends of the support plate 801 are integrally formed with square installation tubes 802. The support plate 801 is fitted to the precast filling block 7. The upper and lower square installation tubes 802 are fitted to the inner top and inner bottom of the beam socket 2, respectively. Each of the upper and lower square installation tubes 802 is provided with a vertically arranged first self-tapping screw 803 and a horizontally arranged second self-tapping screw 804. The first self-tapping screw 803 passes through the square installation tube 802 and is inserted into the steel beam 1. The second self-tapping screw 804 passes through the wall panel assembly 9 and the square installation tube 802 in sequence, and is finally inserted into the steel beam 1.

[0035] Those skilled in the art will understand that when the installation component 8 is used in this invention, the two square installation tubes 802 are fixedly installed on the inner top and inner bottom of the beam socket 2 by the first self-tapping screws 803 on the upper and lower sides. At the same time, the support plate 801 will be fitted with the precast filling block 7 to fix and reinforce the precast filling block 7. Then, the second self-tapping screw 804 passes through the wall panel component 9 and the square installation tube 802 in sequence, and finally passes through the steel beam 1, thereby fixing and installing the wall panel component 9.

[0036] Example 7 Furthermore, the wall panel assembly 9 includes a first wall panel 901 and a second wall panel 902 arranged inside and outside. One side of the first wall panel 901 is fitted with the square mounting tube 802, and the outer side of the first wall panel 901 is flush with the outer end of the beam socket 2. The second wall panel 902 is fitted with the first wall panel 901. The second self-tapping screw 804 passes through the second wall panel 902, the first wall panel 901, and the square mounting tube 802 in sequence, and finally passes through the precast filling block 7.

[0037] Those skilled in the art will understand that the first wall panel 901 in this invention is made of magnesium oxide board, and the second wall panel 902 is made of cement fiberboard. Both magnesium oxide board and cement fiberboard have the characteristics of high temperature resistance, flame retardancy, sound absorption and shock absorption, waterproof and moisture-proof, insect-proof, lightweight and corrosion-resistant, which are beneficial to the waterproof and moisture-proof properties of the beam socket structure, and prevent mold growth in the internal structure, thus affecting the structural strength.

[0038] Example 8 The building structure includes a wall 12 and a floor slab 13. The steel beam 1 is supported between the wall 12 and the floor slab 13. The outer side of the second wall panel 902 is flush with the side wall of the wall 12. The outer side of the second wall panel 902 and the side wall of the wall 12 are covered with wire mesh and coated with an outer coating 14.

[0039] Those skilled in the art will understand that the outer coating 14 in this invention is a putty layer. By laying wire mesh, the tensile force caused by the difference in thermal expansion and contraction at the joint between the second wall panel 902 and the wall 12 can be effectively offset, reducing the risk of cracks in the outer coating 14. It can also enhance the overall integrity, making the second wall panel 902 and the wall 12 connected as a whole, reducing local cracking of the outer coating 14 due to strength differences.

[0040] In addition, the wire mesh serves as a skeleton structure, which can significantly improve the bonding strength between the outer coating 14 and the second wall panel 902 and the wall 12, preventing the outer coating 14 from becoming hollow or peeling off. Moreover, during an earthquake, the wire mesh can disperse stress, reducing the risk of large-area detachment of the outer coating 14. The combination of the outer coating 14 and the wire mesh can seal micro-cracks and improve the waterproof performance of the wall 12.

[0041] Example 9 Furthermore, the bottom of the steel beam 1 and the wall 12 are filled with polymer mortar containing an elastic modifier, which forms a flexible buffer layer 15 after curing.

[0042] Those skilled in the art will understand that the flexible buffer layer 15 provided in this invention allows the steel beam 1 and the wall 12 to undergo different degrees of compression deformation under different pressures, thereby reducing the assembly precision between the steel beam 1 and the wall 12 and allowing the steel beam 1 and the wall 12 to have a certain degree of deformation after assembly.

[0043] In addition, the mortar with added elastic epoxy modifier has a tensile strength of over 10MPa, effectively supporting the structural load, while its flexural strength is ≥6MPa, ensuring that the bond strength between steel beam 1 and wall 12 is ≥1.0MPa, thus guaranteeing long-term stability.

[0044] The method for filling sockets in prefabricated beams includes the following steps: S1. Before filling, first remove debris and dust from the beam socket 2, and rinse and moisten it with a high-pressure water gun. Then, apply anti-rust paint to the beam socket. After the anti-rust paint dries, the filling work can be carried out. S2. When filling, first fill the two side beam sockets 2 of the steel beam 1 with rock wool board 3, and then install the sound insulation board 4. When installing the sound insulation board 4, a cavity sound insulation layer needs to be left between the sound insulation board 4 and the rock wool board 3. Then, first install the inner L-shaped angle steel 501 on the inner top and inner bottom of the beam socket 2 with fixing screws 502. When installing the inner L-shaped angle steel 501, the vertical plate of the L-shaped angle steel 501 needs to be set outward. Then fill the sound insulation board 4 into the beam socket 2, so that one side of the sound insulation board 4 is attached to the outside of the vertical plate of the L-shaped angle steel 501. Then install the outer L-shaped angle steel 501 on the inner top and inner bottom of the beam socket 2 with fixing screws 502, so that the sound insulation board 4 is sandwiched between the vertical plates of the left and right L-shaped angle steel 501. S3. Then, fireproof layer 6 and precast filling block 7 are filled into beam socket 2. Fireproof layer 6 is filled between external L-shaped angle steel 501 and precast filling block 7. When filling precast filling block 7, water-swellable rubber strip 11 is set in the gap between the contact surface of precast filling block 7 and beam socket 2. Then, the upper and lower square mounting tubes 802 are fixedly installed on the inner top and inner bottom of beam socket 2 by the first self-tapping screws 803 on the upper and lower sides. At the same time, the support plate 801 will be attached to the precast filling block 7 to fix and strengthen the precast filling block 7. S4. Finally, the first wall panel 901 is attached to the outside of the two square mounting tubes 802, and then the second wall panel 902 is attached to the outside of the first wall panel 901. Then, the second self-tapping screw 804 is passed through the second wall panel 902, the first wall panel 901 and the square mounting tube 802 in sequence, and finally passed through the prefabricated filling block 7. Then, the outer side of the second wall panel 902 and the side wall of the wall 12 are integrally wire meshed and plastered to complete the filling.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.

Then install the outer L-shaped angle steel (501) in the inner top and inner bottom of the beam socket (2) with fixing screws (502) so that the sound insulation board (4) is sandwiched between the vertical plates of the left and right L-shaped angle steel (501). S3. Then fill the beam socket (2) with fireproof layer (6) and prefabricated filling block (7). The fireproof layer (6) is filled between the outer L-shaped angle steel (501) and the prefabricated filling block (7). When filling the prefabricated filling block (7), water-swellable rubber strip (11) is set in the gap between the prefabricated filling block (7) and the beam socket (2). Then, the two square mounting tubes (802) are fixedly installed in the inner top and inner bottom of the beam socket (2) by the first self-tapping screws (803) on the upper and lower sides. At the same time, the support plate (801) will be attached to the prefabricated filling block (7) to fix and strengthen the prefabricated filling block (7). S4. Finally, the first wall panel (901) is attached to the outside of the two square mounting tubes (802), and the second wall panel (902) is attached to the outside of the first wall panel (901). Then, the second self-tapping screw (804) is passed through the second wall panel (902), the first wall panel (901) and the square mounting tube (802) in sequence, and finally passed into the prefabricated filling block (7). Then, the outer side of the second wall panel (902) and the side wall of the wall (12) are plastered together with the mesh to complete the filling.
