Abstract
Description
Technical Field
[0001] This utility model relates to the field of prefabricated housing technology, specifically to an adjustable crossbeam for the steel frame of prefabricated housing. Background Technology
[0002] Prefabricated construction refers to transferring a large amount of on-site work from traditional construction methods to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are prefabricated in factories, transported to the construction site, and assembled on-site using reliable connection methods. Prefabricated buildings mainly include precast concrete structures, steel structures, and modern wood structures. Because they adopt standardized design, factory production, assembly construction, information management, and intelligent applications, they represent modern industrialized production methods. In the construction of prefabricated houses, beams are important load-bearing structural components, and their performance is crucial to the overall stability and safety of the house. Existing prefabricated house steel frame beams often have the problem of inconvenient adjustment, making it difficult to adapt to different architectural designs and site requirements.
[0003] A beam lifting device, as described in application number CN202221929820.5, includes lifting lugs, a beam body, and hanging plates on both sides of the beam body. The hanging plates are provided with holes for connecting hooks, and are multi-hole plates with the holes distributed along the length of the beam body. This utility model is suitable for lifting long goods, such as the lifting of mechanical arm components for engineering trolleys. During lifting, the holes on the hanging plates can be flexibly selected according to the length of the goods being lifted, thereby changing the hook distance, better stabilizing the center of gravity of the goods, and making the lifting process smoother. However, when using adjustable beams to meet different span requirements, uneven settlement, and adjustments to the indoor space layout, traditional beams cannot flexibly change their structure, leading to many limitations in building construction and use, such as insufficient space utilization, structural stress concentration causing safety hazards, etc., increasing construction costs and the difficulty of later modifications.
[0004] Therefore, in view of this, we studied and improved the existing structure to address its shortcomings, and proposed an adjustable crossbeam for the steel frame of prefabricated houses. Utility Model Content
[0005] The purpose of this invention is to provide an adjustable crossbeam for the steel frame of prefabricated houses to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an adjustable crossbeam for a prefabricated house steel frame, comprising a crossbeam body and a protective mechanism, characterized in that the protective mechanism is fixedly connected to the outer surface of the crossbeam body, and the protective mechanism includes an anti-corrosion layer fixedly connected to the outer surface of the crossbeam body, a fireproof layer is fixedly connected to the outer surface of the anti-corrosion layer, and a reflective layer is fixedly connected to the outer surface of the fireproof layer.
[0007] Preferably, the main body of the crossbeam has a slider internally slidably connected, and an adjustment frame is fixedly connected to one side of the slider.
[0008] Preferably, the inner surface of the adjustment frame is threaded with a locking bolt, and the outer surface of the adjustment frame is fixedly connected with a connecting ear plate.
[0009] Preferably, a vibration damping and sound insulation mechanism is provided on one side of the connecting ear plate, and the vibration damping and sound insulation mechanism includes a locking pin threaded to the inner surface of the connecting ear plate, a spring sleeved on the outer surface of the locking pin, and sound-absorbing cotton fixedly connected to one side of the connecting ear plate, and a vibration damping rubber pad fixedly connected to one side of the sound-absorbing cotton.
[0010] Preferably, a column is provided on one side of the connecting ear plate, and multiple sets of mounting holes are evenly opened on the inner surface of the column.
[0011] Preferably, the inner surface of the crossbeam body is provided with an installation groove, and the crossbeam body is fixedly connected with reinforcing ribs.
[0012] Preferably, a stress-dispersing block is fixedly connected inside the main body of the crossbeam, and a drainage groove is provided on the inner wall of the main body of the crossbeam.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model effectively achieves corrosion prevention, fire prevention and energy saving through the setting of the protective mechanism. The protective mechanism works in conjunction with the overall structure of the main beam to reduce the frequency of use of indoor air conditioning and other refrigeration equipment, reduce energy consumption and achieve energy saving. At the same time, humidity-sensitive materials are added to the anti-corrosion coating. When the ambient humidity is high, the humidity-sensitive materials will promote the active ingredients in the anti-corrosion coating to react faster and form a denser anti-corrosion protective film on the surface of the main beam.
[0015] 2. This utility model, through the setting of a shock-absorbing and sound-insulating mechanism, can absorb the impact force generated by factors such as building vibration and wind, reduce structural wear and damage, prevent the main body of the beam from shifting during use, and ensure that the main body of the beam remains stable. When the building is subjected to vibration or wind, the shock-absorbing rubber pad can not only buffer the impact force, but also absorb the noise generated by the vibration. Working together with the fireproof and heat-insulating layer, the fireproof and heat-insulating layer blocks heat transfer while the noise suppression mechanism reduces the transmission of indoor and outdoor noise, creating a good living environment.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1-3As shown, an adjustable crossbeam for a prefabricated house steel frame includes a crossbeam body 1 and a protective mechanism 2. The protective mechanism 2 is fixedly connected to the outer surface of the crossbeam body 1, and the protective mechanism 2 includes an anti-corrosion layer 201 fixedly connected to the outer surface of the crossbeam body 1. A fireproof layer 202 is fixedly connected to the outer surface of the anti-corrosion layer 201, and a reflective layer 203 is fixedly connected to the outer surface of the fireproof layer 202. The crossbeam body 1 is made of high-strength alloy steel, possessing excellent compressive and bending resistance. The anti-corrosion layer 201 uses high-performance anti-corrosion materials such as epoxy zinc-rich paint, effectively preventing the steel beam from rusting and corroding, extending the service life of the crossbeam. The fireproof layer 202 improves the fire resistance of the crossbeam and also provides heat insulation, reducing heat transfer between indoors and outdoors and improving the energy efficiency of the house. The reflective layer 203 reflects heat from sunlight, reducing the solar radiation heat absorbed by the house.
[0023] like Figure 1 As shown, a slider 3 is slidably connected inside the main body 1 of the crossbeam, and an adjustment frame 4 is fixedly connected to one side of the slider 3. A locking bolt 5 is threadedly connected to the inner surface of the adjustment frame 4, and a connecting ear plate 6 is fixedly connected to the outer surface of the adjustment frame 4. The adjustment frame 4 is slidably connected to the main body 1 of the crossbeam through the slider 3. When the appropriate length is adjusted, tightening the locking bolt 5 can fix the slider 3 on the main body 1 of the crossbeam. The connecting ear plate 6 is used to connect with the column 8 of the steel frame.
[0024] Furthermore, a vibration damping and sound insulation mechanism 7 is provided on one side of the connecting ear plate 6. The vibration damping and sound insulation mechanism 7 includes a locking pin 701 threaded to the inner surface of the connecting ear plate 6. A spring 702 is sleeved on the outer surface of the locking pin 701. A sound-absorbing cotton 703 is fixedly connected to one side of the connecting ear plate 6, and a vibration damping rubber pad 704 is fixedly connected to one side of the sound-absorbing cotton 703. When the main body of the crossbeam 1 is installed in place and adjusted, the locking pin 701 is fixed to the corresponding pin hole on the column 8. The elastic force provided by the spring 702 makes the locking pin 701 tightly fixed, preventing the main body of the crossbeam 1 from shifting during use. The vibration damping rubber pad 704 has good elasticity and can absorb the impact force generated by factors such as house vibration and wind, reducing the wear and damage of the structure. The sound-absorbing cotton 703 absorbs the noise generated by vibration, reduces the transmission of indoor and outdoor noise, and improves the living comfort of the house.
[0025] Furthermore, a column 8 is provided on one side of the connecting ear plate 6, and multiple sets of mounting holes 9 are evenly opened on the inner surface of the column 8. A mounting groove 10 is opened on the inner surface of the crossbeam body 1, and a reinforcing rib 11 is fixedly connected inside the crossbeam body 1. A level can be placed in the mounting groove 10 to observe the level and judge the levelness of the crossbeam body 1. The reinforcing rib 11 is triangular, which enhances the bending and shear resistance of the crossbeam body 1 and improves the load-bearing capacity of the crossbeam.
[0026] Furthermore, a stress-dispersing block 12 is fixedly connected inside the main body of the crossbeam 1, and a drainage groove 13 is provided on the inner wall of the main body of the crossbeam 1. The stress-dispersing block 12 is made of high-strength and high-toughness alloy material. When the main body of the crossbeam 1 is subjected to large pressure or bending moment, the concentrated stress is dispersed to different parts of the crossbeam. The drainage groove 13 can drain water in time, avoid the steel beam from being in a humid environment for a long time, extend the service life of the anti-corrosion coating, and enhance the anti-corrosion performance of the main body of the crossbeam 1.
[0027] Working principle: When using this adjustable crossbeam for prefabricated housing steel frame, firstly, the crossbeam body 1 is hoisted to the installation position. The position of the adjustment frame 4 is moved by the slider 3 to adjust the length of the crossbeam body 1 to adapt to the spacing of the steel frame columns 8. The locking bolts 5 are tightened to fix the length. Then, the crossbeam body 1 is placed on top of the column 8. At the same time, the level inside the mounting groove 10 is observed to ensure that the crossbeam body 1 is level. After adjustment, the spring 702 is sleeved on the outside of the locking pin 701. The connecting ear plate 6 is installed using the locking pin 701 to fix the position of the crossbeam body 1. The sound-absorbing cotton 703 and the shock-absorbing rubber pad 704 of the vibration damping and sound insulation mechanism 7 are installed at the connection between the crossbeam body 1 and the column 8. The surface of the crossbeam body 1 is covered with a protective mechanism 2 consisting of an anti-corrosion layer 201, a fireproof layer 202, and a reflective layer 203 to protect the crossbeam body 1. Finally, the water inside the crossbeam body 1 is drained through the drainage groove 13. This is the working principle of this adjustable crossbeam for prefabricated housing steel frame.
