Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a prefabricated integrated floor slab connection device for wooden structures. Background Technology

[0002] Prefabricated wood structure integrated floor slabs are a type of wood structure roofing system built using a "factory prefabrication, on-site assembly" model. The core of this system involves standardizing key components such as wood trusses, beams, panels, and connectors in a factory, then transporting them to the construction site after quality inspection. Specialized auxiliary equipment is then used to quickly assemble them into a complete floor slab structure. This system combines the advantages of wood structures (low carbon emissions, environmental friendliness, and thermal insulation) with the efficiency, speed, and precision control of prefabricated buildings. It is suitable for various scenarios, including residential buildings, cultural and tourism buildings, and public venues. Designs can be tailored to achieve large spans, pitched roofs, or flat roofs. Compared to traditional on-site fabrication of wood structure floor slabs, the construction cycle is shortened, and the component damage rate is reduced. This makes it an important roofing form for promoting the industrialization and green development of wood structure buildings.

[0003] In the field of prefabricated timber structure buildings, the connection and installation of integrated floor slabs is a crucial step. Traditional connection methods have many shortcomings. On the one hand, for floor slabs with sloping tops, there is a lack of effective restraint mechanisms. Under the influence of gravity, the floor slabs are prone to slipping and detaching from the splicing structure, posing risks to construction safety and structural stability. On the other hand, aligning two floor slabs often requires repeated manual adjustments, which is not only labor-intensive and time-consuming but also difficult to guarantee alignment accuracy. Due to the lack of a linkage adjustment structure, precise alignment cannot be achieved through the coordinated action of components. Alignment deviations can easily affect the tightness of the floor slab connection and the stability of the overall structure, making it difficult to meet the requirements of efficient and precise construction in prefabricated buildings. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a prefabricated integrated wooden floor slab connection device, which has the advantages of effective limiting and fall prevention and rapid alignment. It solves the problems in the background technology where the traditional connection method lacks effective limiting for floor slabs with slanted tops, leading to easy slippage of the floor slabs, and relies on repeated manual adjustments during floor slab alignment, which is labor-intensive, time-consuming, and difficult to guarantee accuracy.

[0005] To achieve the aforementioned objectives of effective limiting and fall prevention and rapid alignment, this utility model provides the following technical solution: a prefabricated wood structure integrated floor slab connection device, comprising a load-bearing inclined beam, with connecting beams installed on both sides of the middle of the load-bearing inclined beam, and multiple splicing grooves opened on the top surfaces of the two connecting beams, with multiple connecting frame members threadedly connected between the load-bearing inclined beam and the connecting beam, a floor slab splicing groove opened in the middle of the upper surface of one of the connecting frame members, and the floor slab splicing grooves being mutually aligned, with an output groove extending through the middle of the connecting frame member, and swing grooves opened on both sides of the top of the connecting frame member, with swing limiting plates rotatably connected to the middle of the two swing grooves, and a contact angle opened on one side of the bottom of one of the swing limiting plates, with a floor slab placed between the splicing groove and the floor slab splicing groove, and beveled contact blocks installed on both sides of the floor slab by screws, and the beveled contact blocks abutting against each other.

[0006] As a further embodiment of this utility model: an extension plate is slidably connected through the two swing limiting plates on the side away from the abutting angle, an mounting plate is fixedly connected to the side of the two extension plates away from the swing limiting plates, and an L-shaped abutting plate is fixedly connected to the side of the two mounting plates away from the extension plates.

[0007] As a further improvement of this utility model: an output plate is provided at the bottom center of the connecting frame, and the output plate slides in the output groove.

[0008] As a further embodiment of this utility model: a fixing plate is fixedly connected to one side of the bottom of the connecting frame, a bolt is threaded through and connected to the middle of the fixing plate, and the side of the bolt away from the fixing plate is rotatably connected to the output plate.

[0009] As a further improvement of this utility model: the side of the output plate away from the bolt abuts against the L-shaped contact plate.

[0010] As a further improvement of this utility model: splicing grooves are provided on both sides of the top of the load-bearing inclined beam, and the splicing grooves and splicing slots cooperate with each other.

[0011] As a further improvement of this utility model: the L-shaped contact plate passes through the middle of the mounting plate and has a screw groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the angled contact block and the swing limiting plate abut against each other, thereby achieving instant positioning of the floor slab in the top-cut angled state. When the floor slab slides down due to gravity, it can quickly respond and form a stable constraint, preventing it from detaching from the splicing groove and the floor slab splicing groove. Compared with the traditional connection method, which lacks effective positioning and the floor slab is prone to slippage, this mechanism fundamentally eliminates construction safety hazards, while ensuring the initial stability of the structural connection. It does not require additional manual temporary fixing, greatly improving construction safety and efficiency, making the construction process smoother, and reducing the occurrence of accidents.

[0013] Through the coordinated action of components such as the swing limit plate, extension plate, L-shaped contact plate, and bolts, the alignment of the floor slabs is achieved. The dual adjustment of swing transmission and bolt drive allows the floor slabs to slide smoothly into the alignment state within the splicing groove, replacing the traditional method of repeated manual adjustment, reducing manpower and time consumption, avoiding the problem of insufficient connection tightness caused by human operation errors, significantly improving the stability of the overall structure, and making the building quality more guaranteed.

[0016] 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.

[0017] Please see Figures 1-3In this embodiment of the utility model, a prefabricated wood structure integrated floor slab connection device includes a load-bearing inclined beam 1, with connecting beams 2 installed on both sides of the middle of the load-bearing inclined beam 1. Multiple splicing grooves 3 are formed on the top surface of both connecting beams 2. Multiple connecting frame 5s are threadedly connected between the load-bearing inclined beam 1 and the connecting beams 2. A floor slab splicing groove 6 is formed in the middle of the upper surface of one connecting frame 5, and the floor slab splicing groove 6 is identical to the splicing groove 3. An output groove 7 is formed through the middle of the connecting frame 5. Swing grooves 8 are formed on both sides of the top of the connecting frame 5. Swing limiting plates 9 are rotatably connected to the middle of both swing grooves 8. A clash angle 10 is formed on one side of the bottom of one swing limiting plate 9. A floor slab 18 is placed between the splicing groove 3 and the floor slab splicing groove 6. Clash angle clash blocks 19 are installed on both sides of the floor slab 18 by screws. The clash angle clash blocks 19 are installed on the outer wall of the floor slab 18 by screws. The floor slab 18 is made of wood. Pre-drilled holes are required in the floor slab 18 to avoid damage to the wooden structure of the floor slab 18 and protect its integrity. Compared with the traditional connection method that may require pre-drilled holes in the floor slab, this method can reduce the impact of the holes on the load-bearing capacity of the wooden board. In addition, the angled contact block 19 and the contact angle 10 abut against each other. When installing the floor slab 18 with the top cut at an angle, the floor slab 18 is first placed between the splicing groove 3, the splicing groove 4 and the floor slab splicing groove 6. At the same time, the angled contact blocks 19 installed by screws on both sides of the floor slab 18 are placed between the two swing limiting plates 9 that are rotatably connected in the inner cavity of the connecting frame 5. Since the floor slab 18 is in an inclined state, it will slide down under the action of gravity. When it slides down, it will drive the angled contact block 19 to slide down. When the angled contact block 19 slides, it will abut against the contact angle 10 opened on the swing limiting plate 9 to limit it, thereby preventing the floor slab 18 from falling off the splicing groove 3 and the floor slab splicing groove 6 due to gravity. Two swing limiting plates 9 are slidably connected to extension plates 11 on the side away from the contact angle 10. Mounting plates 12 are fixedly connected to the side of each extension plate 11 away from the swing limiting plate 9. L-shaped contact plates 13 are fixedly connected to the side of each mounting plate 12 away from the extension plates 11. The L-shaped contact plates 13 penetrate the middle of the mounting plates 12 and have screw grooves 14. Simultaneously, the L-shaped contact plates 13 drive the extension plates 11 to slide within the swing limiting plate 9, extending them. At the same time, the angled contact block 19 contacts the contact angle 10 of the swing limiting plate 9, causing the swing limiting plate 9 to swing within the swing groove 8. The swinging of the swing limiting plate 9 causes the extension plates 11, mounting plates 12, and L-shaped contact plates 13 to swing and contact the floor slab 18. Then, screws passing through the screw grooves 14 are used to fix the three components. An output plate is provided at the bottom center of the connecting frame 5. 17, and the output plate 17 slides in the output groove 7. A fixed plate 15 is fixedly connected to one side of the bottom of the connecting frame 5. A bolt 16 is threaded through the middle of the fixed plate 15 and connected to it. The side of the bolt 16 away from the fixed plate 15 is rotatably connected to the output plate 17. The side of the output plate 17 away from the bolt 16 abuts against the L-shaped abutment plate 13. Splicing grooves 4 are opened on both sides of the top of the bearing inclined beam 1. The splicing grooves 4 and splicing grooves 3 cooperate with each other. When the L-shaped abutment plate 13 swings, the bottoms of the two L-shaped abutment plates 13 approach each other and slide in the output groove 7. Then, the bolt 16 is rotated to move it forward in the fixed plate 15 and drive the output plate 17 to slide in the output groove 7, abut against the L-shaped abutment plate 13, and cause it to drive the mounting plate 12 to slide up. The screw drives the floor slab 18 to move up, so that one end slides and aligns in the splicing groove 4.

[0018] The working principle of this utility model is as follows: When installing the floor slab 18 with a slanted top, the floor slab 18 is first placed between the splicing groove 3, the splicing slant groove 4, and the floor slab splicing groove 6. At the same time, the angled abutment blocks 19 installed by screws on both sides of the floor slab 18 are placed between the two swing limiting plates 9 that are rotatably connected in the inner cavity of the connecting frame 5. Since the floor slab 18 is in an inclined state, it will slide down under the action of gravity. When it slides down, it will drive the angled abutment blocks 19 to slide down. When the angled abutment blocks 19 slide, they will abut against the abutment angles 10 opened on the swing limiting plates 9 to limit the movement, thereby preventing the floor slab 18 from falling off due to gravity and separating from the splicing groove 3 and the floor slab splicing groove 6. Simultaneously, after the angled contact block 19 abuts against the angled contact 10 of the swing limiting plate 9, it causes the swing limiting plate 9 to swing within the swing groove 8. The swing of the swing limiting plate 9 causes the extension plate 11, the mounting plate 12, and the L-shaped contact plate 13 to swing and contact the floor slab 18. Then, the three are fixed by screws passing through the screw groove 14. When the L-shaped contact plate 13 swings, the bottoms of the two L-shaped contact plates 13 approach each other and slide within the output groove 7. Then, the bolt 16 is rotated to move it forward within the fixing plate 15 and cause the output plate 17 to slide within the output groove 7, abutting against the L-shaped contact plate 13, causing it to drive the mounting plate 12 to slide upward. The screws drive the floor slab 18 upward, causing one end to slide and align within the splicing groove 4. At the same time, the L-shaped contact plate 13 drives the extension plate 11 to slide within the swing limiting plate 9 to achieve extension.
