Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a prefabricated beam for an assembled house. Background Art

[0002] In the construction industry, with the enhancement of environmental awareness and the advancement of technology, prefabricated buildings have received widespread attention due to their high efficiency, energy saving, and green environmental protection. Compared with traditional cast-in-place concrete structures, prefabricated buildings greatly shorten the construction period and significantly reduce the amount of on-site work by factory-producing components and assembling them on site. However, in actual application, it was found that due to the high assembly precision requirements and the direct impact of the connection method between components on the safety and stability of the overall structure, how to ensure reliable connection between prefabricated components has become one of the problems to be solved;

[0003] Existing prefabricated beams for assembled buildings mainly include two categories: steel structure beams and reinforced concrete beams. Among them, steel structure beams are usually spliced ​​by bolt connection or welding; while reinforced concrete beams mostly rely on the method of reserved dowel bars and grouting anchoring to achieve connection. Although these two methods can meet the requirements of connection strength to a certain extent, there are still many limitations in the actual engineering application process. For example, for bolt connections, when encountering extreme situations such as earthquakes, it is easy to loosen or even fall off; although welding can provide higher stiffness and shear resistance, the application scope is limited due to problems such as the difficulty in ensuring the quality of welds and low construction efficiency. As for reinforced concrete beams, although they have good bearing capacity and durability, the construction process is not only complicated, but the grouting quality is also greatly affected by environmental factors, which may affect the final connection reliability. In the process of realizing this application, the inventor found that the prior art has the following problems:

[0004] The prefabricated beam connection technology for assembled buildings that is currently popular on the market cannot completely overcome the disadvantages of unstable connection, difficult construction and high maintenance costs. At the same time, it often does not have shock-absorbing mechanisms and detection functions. When internal cracks or other defects occur in the main beam body, it is impossible to discover them in time for maintenance work. Summary of the invention

[0005] The purpose of this application is to provide a prefabricated beam for an assembled house.

[0006] In the first aspect, the present application provides a prefabricated beam for an assembled house using the following technical solution:

[0007] A prefabricated beam of an assembled house comprises a main beam body, a reinforcement support frame is arranged on one side of the main beam body, the reinforcement support frame comprises transverse reinforcement ribs and longitudinal ribs, the transverse reinforcement ribs are evenly distributed on the inner wall surface of the main beam body, a longitudinal rib is arranged on one side of the transverse reinforcement ribs, the longitudinal ribs are arranged perpendicular to the cross-section of the main beam body, the transverse reinforcement ribs and the longitudinal ribs are connected to the main beam body by welding, both ends of the main beam body are provided with connection nodes, a locking groove is arranged on the side of the connection node away from the main beam body, an adjacent beam body is arranged on one side of the main beam body, the adjacent beam body is embedded in the locking groove, the outer walls of the ends of the adjacent beam bodies are arranged with positioning pins, the inner walls of the locking grooves are arranged with limiting grooves, the positioning pins are embedded in the limiting grooves, a No. 1 through hole is arranged on one side of the middle of the connection node, a No. 2 through hole is arranged on one side of the end of the adjacent beam body, the No. 1 through hole corresponds to the No. 2 through hole, and a fixed connecting rod is penetrated through the middle of the No. 1 through hole and the No. 2 through hole.

[0008] By adopting the above technical scheme, the main beam body adopts Q345D low-alloy high-strength steel with good toughness and weldability. The transverse reinforcement ribs are made of hot-rolled round steel with a diameter of 16mm, and the thickness of the longitudinal ribs is 8mm. The materials are all ordinary carbon structural steel plates. The rigidity and bending resistance of the entire beam body are enhanced by the setting of the reinforced support frame. At the same time, when the adjacent beam bodies are embedded in the locking grooves, the positioning pins are embedded in the limit grooves, thereby realizing the precise alignment of the connection between the adjacent beam bodies and the main beam body. When the adjacent beam bodies are embedded in the locking grooves, the No. 1 through hole and the No. 2 through hole are in the same straight line. The connection and fixing of the adjacent beam bodies are realized by passing the fixed connecting rod through the No. 1 through hole and the No. 2 through hole.

[0009] A limiting head is provided at the end of the fixed connecting rod, and a fixed connecting box is provided on one side of the bottom of the connecting node, and the end of the fixed connecting rod away from the limiting head passes through the No. 1 through hole and the No. 2 through hole to extend into the fixed connecting box, and a connecting groove is provided on one side of the bottom end of the fixed connecting rod, and a connecting component is provided inside the fixed connecting box, and the connecting component includes a threaded barrel, a threaded rod, a top column, a limiting rod and an adjusting knob, and a threaded barrel is connected to an inner wall of one side of the fixed connecting box through a bearing, and a threaded rod is threadedly connected to the inner wall of one end of the threaded barrel, and the end of the threaded rod away from the threaded barrel is connected to the top column, and one end of the top column passes through the connecting groove and extends to the inner wall of the fixed connecting box to abut against it, and limiting rods are connected on both sides of one end of the top column close to the threaded rod, and one end of the limiting rod away from the top column passes through the edge of the inner wall of the fixed connecting box.

[0010] By adopting the above technical scheme, the fixed connecting rod passes through the No. 1 through hole and the No. 2 through hole and the bottom end is embedded in the fixed connecting box. The threaded barrel is driven to rotate by twisting the adjusting knob. The rotation of the threaded barrel drives the threaded rod to perform reciprocating translational motion. The translation of the threaded rod drives the top column to perform synchronous translational motion. The top column moves through the connecting groove to realize the locking function of the fixed connecting rod. The fixed connecting rod can be fixed by the connecting assembly, so as to firmly connect the main beam body and the adjacent beam body. Therefore, workers only need to lift each prefabricated beam in turn and place it in the corresponding position according to the instructions on the drawing and fix them to each other by matching and fixing the connecting nodes to quickly build the required load-bearing frame structure. A firm connection can be achieved without using the method of reserved dowel bars and grouting anchoring.

[0011] An adjusting knob is connected to an outer wall of one side of the fixed connection box, and an output end of the adjusting knob is connected to a threaded barrel. The threaded barrel is rotated by twisting the adjusting knob, and the rotation of the threaded barrel drives the threaded rod to perform reciprocating translational motion, and the translation of the threaded rod drives the top column to perform synchronous translational motion.

[0012] By adopting the above technical solution, the adjusting knob plays a driving role, and by twisting the adjusting knob, the locking function of the top column to fix the connecting rod can be driven.

[0013] A sealing rubber gasket is provided on the inner wall at the edge of the locking groove, and an abutment plate is provided at the center of the inner wall of the locking groove. A No. 1 spring is arranged and connected to one side of the abutment plate, and one end of the No. 1 spring away from the abutment plate abuts against the inner wall of the locking groove.

[0014] By adopting the above technical solution, the sealing rubber gasket has a thickness of 5mm and a moderate hardness. By arranging a circle of sealing rubber gasket on the periphery of the connection node, it can effectively prevent external moisture from invading and causing internal corrosion damage, thereby improving the service life of the steel beam. After the adjacent beam body is embedded in the locking groove, it will abut against the abutment plate and push the abutment plate to move horizontally deep into the inner wall, thereby squeezing the No. 1 spring to contract.

[0015] The inner walls of both sides of the locking groove adjacent to the abutment plate are provided with movable grooves, and connecting plates are embedded in the movable grooves. The abutment plates are connected to two groups of connecting plates.

[0016] By adopting the above technical solution, the two groups of connecting plates can perform translational movement in the movable grooves, and the connecting plates can be driven to perform translational movement by the movement of the abutting plates.

[0017] The adjacent beams are provided with slots on both sides close to the connecting plates, and the two groups of movable slots are provided with movable cavities on one side close to the edge of the connecting node, and a top block is embedded in the middle of the movable cavity, and the top block matches the slots.

[0018] By adopting the above technical solution, the top block is embedded in the card slot to achieve preliminary positioning and fixation of the adjacent beam body embedded in the locking slot, and the beam body is automatically locked and fixed while performing the limiting work. After limiting, the No. 1 through hole and the No. 2 through hole are in the same straight line to avoid offset movement during connection, so that the fixed connecting rod can easily perform the penetration and fixing work.

[0019] The end of the top block is in contact with the connecting plate, and the end of the top block away from the connecting plate is connected to a connecting rod. A No. 2 spring is sleeved on the middle outer wall of the connecting rod. The two ends of the No. 2 spring are respectively in contact with the top block and the inner wall of the active cavity, and the end of the connecting rod away from the top block is connected to a pull block through a connecting node.

[0020] By adopting the above technical scheme, when the adjacent beam bodies are embedded in the locking groove, they will abut against the abutment plate and push the abutment plate to move horizontally deep into the inner wall. The movement of the abutment plate drives the connecting plate to move synchronously. The connecting plate moves in the direction of the abutment plate and thus moves out of the outer wall of the movable cavity. The top block loses its restriction and is pushed out of the movable cavity by the rebound force of the No. 2 spring and thus is embedded in the slot, thereby realizing automatic locking and fixed positioning of the adjacent beam bodies. When disassembly is required, the pull block can be pulled to drive the connecting rod and the top block to retract to the movable cavity to separate the top block from the slot for easy subsequent disassembly.

[0021] The inner wall of the main beam body is provided with elastic vibration isolators arranged along the axis, an outer wall of one side of the main beam body is connected with an ultrasonic detection sensor, and a timer is provided on one side of the ultrasonic detection sensor.

[0022] By adopting the above technical solution, the elastic isolator is built into the main beam to play a shock-absorbing and damping effect. When encountering strong vibration impact, it can effectively absorb excess energy and buffer the vibration amplitude to protect the main body of the building from damage. The steel beam can be detected regularly through the ultrasonic detection sensor. When the ultrasonic wave propagates inside the steel beam, it will be reflected and refracted when encountering different media (such as defects or damage). By analyzing the reflected ultrasonic signal, the structure and integrity of the steel beam can be judged. If there are cracks or other defects inside the steel beam, the ultrasonic wave will be reflected when encountering these defects, and the reflected signal will be different from the normal steel beam signal. The ultrasonic detection sensor can be set to a fixed time through the timer, so that it can continuously and regularly monitor the health of the main beam.

[0023] A controller is arranged on one side of the timer, a data processor and a communication unit are arranged inside the controller, and the controller is connected to the ultrasonic detection sensor and the timer through wires.

[0024] By adopting the above technical solution, the controller can control the ultrasonic detection sensor to work at a fixed time. The data from the ultrasonic detection sensor will be transmitted to the data processor for data analysis and processing. When it is analyzed that there are cracks or other defects inside the main beam, the signal will be transmitted to the communication unit. The communication unit can perform wireless communication and wired communication. The signal can be transmitted through the communication unit to facilitate timely repair of the main beam.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The fixed connecting rod passes through the No. 1 through hole and the No. 2 through hole, and the bottom end is embedded in the fixed connecting box. The threaded barrel is driven to rotate by twisting the adjusting knob, and the rotation of the threaded barrel drives the threaded rod to perform reciprocating translational motion. The translation of the threaded rod drives the top column to perform synchronous translational motion. The top column moves through the connecting groove to realize the locking function of the fixed connecting rod. The fixed connecting rod can be fixed by the connecting assembly, so as to firmly connect the main beam body and the adjacent beam body. Therefore, workers only need to lift each prefabricated beam in turn according to the instructions of the drawing and place it in the corresponding position and match and fix it with each other through the connection nodes to quickly build the required load-bearing frame structure. A firm connection can be achieved without using the method of reserved dowel bars and grouting anchoring, which improves the stability of the connection between prefabricated beams of prefabricated houses and effectively avoids the risk of loosening caused by changes in the external environment.

[0027] 2. The elastic isolator is built into the main beam to play a shock-absorbing and damping role. When encountering strong vibration impact, it can effectively absorb excess energy and buffer the vibration amplitude to protect the main body of the building from damage. The ultrasonic detection sensor can be used to perform regular inspections on the steel beam to determine the internal structure and integrity of the steel beam. If there are cracks or other defects inside the steel beam, the ultrasonic wave will be reflected when encountering these defects. The reflected signal will be different from the normal steel beam signal, allowing it to continuously and regularly monitor the health of the main beam, enhance the overall earthquake resistance and disaster prevention characteristics of the system, extend the service life and reduce subsequent operation and maintenance expenses.
