Description

Technical Field

[0001] This utility model relates to the field of lightweight building technology, and in particular to a lightweight building structure with good load-bearing capacity. Background Technology

[0002] Lightweight building structures are a type of building structure system in the field of architectural engineering that takes lightweight as its core design orientation while also taking into account structural stability, functionality, and ease of construction. Its core feature is that by using lightweight and high-strength materials, optimizing component cross-section design, or innovating structural forms, it can significantly reduce the building's self-weight while meeting the basic safety requirements of the building in terms of load-bearing capacity, wind resistance, and earthquake resistance. It is widely applicable to prefabricated buildings, temporary buildings, low-rise residential buildings, auxiliary rooms of industrial plants, and other scenarios.

[0003] In existing lightweight buildings, workers often stand on pre-tied steel mesh to work, which often causes the steel bars on the floor or roof slabs of the building structure to sink, resulting in insufficient load-bearing capacity and cracking of the floor or roof slabs.

[0004] The existing patent (publication number: CN220035794U) describes a lightweight building structure with good load-bearing capacity. It uses aluminum alloy keel and is matched with calcium silicate board and mineral wool board, which have high strength and light weight. They serve as supports and fixation, and will not decompose to produce any toxic or suffocating gases. The lightweight steel structure makes it low-cost, and the cost can be reduced by more than half compared with traditional buildings.

[0005] To address the aforementioned issues, existing patents offer solutions. However, when using such lightweight building structures, they typically rely on direct bolt fixing. Bolt fixing requires pre-drilling multiple mounting holes precisely on the lightweight components, demanding high construction precision. Furthermore, single-node installation necessitates repeated alignment of holes and tightening of bolts, making the operation cumbersome and time-consuming. Especially in large-area assembly scenarios, installation can be hindered due to hole position deviations, making it inconvenient to connect adjacent building structures and reducing the flexibility of use.

[0006] Therefore, a lightweight building structure with good load-bearing capacity is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a lightweight building structure with good load-bearing capacity, which can solve the problem that existing lightweight building structures usually rely on direct bolt fixing during use. Bolt fixing requires multiple installation holes to be accurately drilled in the lightweight components in advance, which requires high construction precision. Moreover, the installation of a single node requires repeated alignment of the holes and tightening of bolts, which is cumbersome and time-consuming. Especially in the case of large-area assembly, the installation is easily hindered by the deviation of the hole position, which makes it inconvenient to connect adjacent building bodies and reduces the flexibility of use.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a lightweight building structure with good load-bearing capacity, comprising a building body, a connecting component provided between two adjacent building bodies, the connecting component comprising a connecting plate, T-shaped grooves provided on both sides of the top of the connecting plate, a T-shaped block fixedly connected to the side of the building body near the connecting plate, and the T-shaped block cooperating with the T-shaped groove, a groove provided on the front side of the top of the connecting plate, a rotating component rotatably connected inside the groove via a bearing, an L-shaped cover plate fixedly sleeved on the surface of the rotating component, and the L-shaped cover plate cooperating with the opening of the T-shaped groove.

[0009] Preferably, the main building structure includes a protective layer, a load-bearing layer, and a thermal insulation layer. The protective layer is made of asbestos-free fiber cement and its thickness is set to 15-30mm.

[0010] Preferably, the load-bearing layer is fixedly connected to the outside of the protective layer, and the load-bearing layer is made of cold-formed thin-walled steel with a thickness of 30-100mm.

[0011] Preferably, the thermal insulation layer is fixedly connected to the outside of the load-bearing layer, and the thermal insulation layer is made of extruded polystyrene material with a thickness of 30-80mm.

[0012] Preferably, the L-shaped cover plate has an internal groove at the end away from the rotating part, and a positioning rod passes through the internal groove. The rear side of the connecting plate has a positioning groove that cooperates with the positioning rod.

[0013] Preferably, a pull ring is fixedly connected to one end of the positioning rod located in the built-in groove, and a tension spring is sleeved on the surface of the positioning rod, with both ends of the tension spring being fixedly connected to the pull ring and the built-in groove, respectively.

[0014] Preferably, an elastic sealing gasket is fitted between the outer wall of the T-shaped block and the inner wall of the T-shaped groove. The elastic sealing gasket is made of EPDM rubber and its thickness is set to 2-5mm.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This application sets up a connecting component, which replaces the traditional bolt fixing with the cooperation of T-shaped blocks and T-shaped slots. It eliminates the need to accurately drill multiple installation holes, greatly reducing the construction accuracy requirements. With the help of a rotatable L-shaped cover plate to seal the opening of the T-shaped slot, and the locking structure of the positioning rod and the positioning slot, it can realize the rapid assembly and stable connection of adjacent building bodies, avoid the installation obstruction problem caused by hole position deviation, significantly simplify the operation process and improve construction efficiency.

[0017] 2. This application sets up a building main body, which adopts a multi-layer composite structure of protective layer + load-bearing layer + thermal insulation layer. This effectively solves the problem of cracking of the panel surface due to insufficient load-bearing capacity in traditional lightweight structures, and achieves a balance of multiple performances such as lightweight, high load-bearing capacity and thermal insulation, thereby meeting the needs of multiple usage scenarios.

Detailed Implementation

[0024] 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.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A lightweight building structure with good load-bearing capacity includes a main building 1. A connecting component 2 is provided between two adjacent main building 1s. The connecting component 2 includes a connecting plate 201. T-shaped grooves 202 are provided on both sides of the top of the connecting plate 201. A T-shaped block 203 is fixedly connected to the side of the main building 1 near the connecting plate 201, and the T-shaped block 203 cooperates with the T-shaped groove 202. A groove is provided on the front side of the top of the connecting plate 201. A rotating component 204 is rotatably connected to the inside of the groove through a bearing. An L-shaped cover plate 205 is fixedly sleeved on the surface of the rotating component 204, and the L-shaped cover plate 205 cooperates with the opening of the T-shaped groove 202.

[0027] In this embodiment: By setting up the connecting component 2, the connecting plate 201 serves as the connecting carrier of the adjacent building body 1 and is the basic support component of the entire connecting component 2. It is used to support the T-slot 202, rotating component 204, and other structures, while providing a stable connection reference for the adjacent building body 1 to ensure the positional accuracy when the two are docked. The T-slot 202 and the T-block 203 cooperate to achieve rapid positioning and docking of the adjacent building body 1 and the connecting plate 201. No precise drilling is required; the initial assembly can be completed simply by inserting the T-block 203 along the T-slot 202. The groove is opened on the top front side of the connecting plate 201. The rotating component 204 is rotatably connected in the groove through a bearing, which can drive the L-shaped cover plate 205 to rotate around the rotating component 204, realizing the opening and closing action of the L-shaped cover plate 205. When the cover is closed, it can cover the opening of the T-shaped groove 202, preventing the T-shaped block 203 from coming out of the T-shaped groove 202, further strengthening the connection stability between the main building 1 and the connecting plate 201. The built-in groove 3 can provide a hidden installation and accommodation space for the pull ring 6, tension spring 7 and positioning rod 4, avoiding the pull ring 6 and tension spring 7 from being exposed to the outside, and preventing them from being damaged by construction collisions, dust accumulation or rainwater erosion. The positioning rod 4 passes through the built-in groove 3. The positioning groove 5 is opened on the rear side of the connecting plate 201. When the L-shaped cover 205 is closed, the positioning rod 4 can be inserted into the positioning groove 5 to fix the L-shaped cover 205 on the connecting plate 201 and prevent the cover from being opened accidentally. The pull ring 6 makes it easy to manually pull the positioning rod 4 to unlock the cover. The tension spring 7 can automatically reset and insert into the positioning groove 5 by pulling the positioning rod 4 with its own elastic force, simplifying the locking operation.

[0028] Specifically, such as Figure 5 As shown, the main building 1 includes a protective layer 101, a load-bearing layer 102, and a thermal insulation layer 103. The protective layer 101 is made of asbestos-free fiber cement material, and its thickness is set to 15-30mm.

[0029] Specifically, such as Figure 5 As shown, the load-bearing layer 102 is fixedly connected to the outside of the protective layer 101. The load-bearing layer 102 is made of cold-formed thin-walled steel and its thickness is set to 30-100mm.

[0030] Specifically, such as Figure 5 As shown, the thermal insulation layer 103 is fixedly connected to the outside of the load-bearing layer 102. The thermal insulation layer 103 is made of extruded polystyrene and its thickness is set to 30-80mm.

[0031] In this embodiment: By setting up the main building 1, the protective layer 101 can provide inner foundation protection for the main building 1, preventing the load-bearing layer 102 from being directly exposed and damaged. It is made of asbestos-free fiber cement, which has inherent fireproof, moisture-proof, and corrosion-resistant properties. It can prevent the erosion of the load-bearing layer 102 by moisture inside the building and minor impacts, and avoids the safety hazards of traditional asbestos materials. Moreover, it is lightweight, meeting the requirements for lightweight construction. As the load-bearing skeleton of the main building 1, the load-bearing layer 102 is a key structure for achieving good load-bearing performance and can bear and transmit loads. The insulation layer, made of cold-formed thin-walled steel, bears all the building's load. Compared to traditional reinforced concrete, it reduces weight by more than 60% (meeting lightweight requirements) while maintaining high bending and shear strength. This ensures sufficient cross-section to withstand the load without exceeding the overall weight limit due to excessive thickness. The thermal insulation layer 103 provides thermal insulation to the main building structure, improving user comfort without adding extra load. Made of extruded polystyrene, it effectively blocks heat exchange between the interior and exterior and has a density of only 0.03-0.04 g / cm³. 3 It is extremely lightweight and hardly increases the load pressure on the load-bearing layer 102. While ensuring the thermal insulation effect, it avoids the building size or weight increase due to excessive thickness.

[0032] Specifically, such as Figure 4 As shown, the L-shaped cover plate 205 has an internal groove 3 at the end away from the rotating part 204, and a positioning rod 4 passes through the inside of the internal groove 3. The rear side of the connecting plate 201 has a positioning groove 5 that cooperates with the positioning rod 4.

[0033] Specifically, such as Figure 4 As shown, a pull ring 6 is fixedly connected to one end of the positioning rod 4 located in the built-in groove 3, and a tension spring 7 is sleeved on the surface of the positioning rod 4. The two ends of the tension spring 7 are fixedly connected to the pull ring 6 and the built-in groove 3, respectively.

[0034] Specifically, such as Figure 3 As shown, an elastic sealing gasket 8 is fitted between the outer wall of the T-shaped block 203 and the inner wall of the T-shaped groove 202. The elastic sealing gasket 8 is made of EPDM rubber and its thickness is set to 2-5mm.

[0035] In this embodiment: Through the above settings, the built-in groove 3 can provide a hidden installation and sliding channel for the positioning rod 4. When the L-shaped cover plate 205 rotates to the position that blocks the opening of the T-shaped groove 202, the positioning rod 4 can pass through the built-in groove 3 and insert into the positioning groove 5 on the rear side of the connecting plate 201 to form a rigid lock. This prevents the cover plate from shifting when the building is subjected to vibration or external force collision, thereby preventing the T-shaped block 203 from coming out of the T-shaped groove 202 and ensuring the reliability of the connection between adjacent building main bodies 1. The pull ring 6 can improve the ease of operation of the positioning rod 4, making it easy for construction personnel to manually pull the positioning rod 4 to achieve quick operation of pulling to unlock and releasing the lock without the need for additional tools. The tension spring 7 can automatically pull the positioning rod when the pull ring 6 is released using elastic force. 4. Reset: This avoids the tedious steps of manually aligning holes, improving assembly efficiency. It also ensures the precise fit between positioning rod 4 and positioning groove 5, reducing human error. The elastic sealing gasket 8 is used to fill the gap between T-block 203 and T-groove 202, achieving sealing and buffering at the connection. On the one hand, it can effectively prevent rainwater, dust and other impurities from entering the connection gap, preventing the T-shaped structure from rusting or accumulating dirt, which would make subsequent disassembly difficult. On the other hand, its elastic properties can buffer the friction and compression between T-block 203 and T-groove 202 when the building expands and contracts due to temperature changes or is subjected to slight vibrations, reducing structural damage. At the same time, it enhances the sealing of the connection, preventing heat loss from indoor and outdoor exchange, and helping to improve the overall energy-saving effect of the building.

[0036] Working principle: First, lift or push a single building body 1 so that the T-shaped block 203 on its side aligns with the opening of the T-shaped groove 202 on one side of the connecting plate 201. Slowly insert the T-shaped block 203 along the length of the T-shaped groove 202 until the building body 1 and the connecting plate 201 are in contact. Repeat the above steps to insert the T-shaped block 203 of the other building body 1 into the T-shaped groove 202 on the other side of the connecting plate 201. This completes the initial docking of adjacent building bodies 1 and connecting plates 201. Then rotate the L-shaped... Cover plate 205 covers the opening of T-shaped groove 202 to prevent T-shaped block 203 from coming out. Then pull the pull ring 6 inside the inner groove 3. After the L-shaped cover plate 205 is fully closed, release the pull ring 6. The tension spring 7 will reset and push the positioning rod 4 through the inner groove 3 and insert it into the positioning groove 5 on the back side of the connecting plate 201 to lock the L-shaped cover plate 205 and realize the stable connection of adjacent building bodies 1. Then, the subsequent building bodies 1 are spliced ​​in sequence until the structural assembly of the preset area is completed.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
