Abstract
Description
Technical Field
[0001] This invention relates to the field of construction, specifically to a prefabricated box-shaped steel-concrete composite prefabricated roof system based on angle steel ribbed steel base plate. Background Technology
[0002] The roof is the uppermost enclosing structure of a building, and it should meet the corresponding functional requirements to provide a suitable internal space environment for the building. The roof is also the load-bearing structure at the top of the building, and is constrained by factors such as materials, structure, and construction conditions.
[0003] The above two inventions have the following structural shortcomings:
[0004] 1. When the bolt holes on the steel base plate and the bolt holes on the angle steel are not aligned and there is an error, it is impossible to adjust in time.
[0005] 2. When angle steel, steel base plate and concrete are poured on the ground, the overall weight is large, which is inconvenient for hoisting. At the same time, it is also inconvenient for workers to install when hoisted to the construction position, which can easily reduce construction efficiency and affect the construction progress. Summary of the Invention
[0006] The purpose of this invention is to provide a prefabricated box-shaped steel-concrete composite prefabricated roof system based on angle steel ribbed steel base plate.
[0007] To achieve this objective, the present invention adopts the following technical solution:
[0008] A prefabricated box-shaped steel-concrete composite prefabricated roof system based on angle steel rib steel base plate is provided, including steel base plate and fixing mechanism. The fixing mechanism includes shielding component and fixing component. Shielding component is symmetrically arranged at the bottom and top of steel base plate, and fixing component is arranged on shielding component.
[0009] Furthermore, the shielding assembly includes four first angle steels and four second angle steels. The four first angle steels are symmetrically arranged at the bottom and top of the steel base plate along its length, and the four second angle steels are symmetrically arranged at the bottom and top of the steel base plate along its width, with each second angle steel having its two ends respectively attached to the outer walls of the two first angle steels.
[0010] Furthermore, the fixing component includes several studs, and several stud holes are evenly spaced on the outer wall of the steel base plate in both the length and width directions, with each stud inserted into a stud hole.
[0011] Furthermore, a locking block is fixed to the bottom of the steel base plate by a first bolt. The locking block has a rectangular through hole, and a support block is inserted inside the rectangular through hole. The support block has a insertion hole, and the locking block has a through hole. A second bolt is inserted into the insertion hole and the through hole.
[0012] Furthermore, each side wall of the support block is fixedly provided with a threaded sleeve, and each threaded sleeve is threadedly connected to a sleeve, with an inner tube inserted inside the sleeve.
[0013] Furthermore, each sleeve has a fixed sleeve rod on its outer wall, an inner rod inserted inside the sleeve rod, the inner rod passes through the sleeve, a telescopic spring is inserted between the inner rod and the sleeve rod, and a hemispherical buckle is fixed at one end of the inner rod near the inner tube. Several slots for the hemispherical buckle to engage are evenly spaced on the outer wall of the inner tube.
[0014] Furthermore, each inner tube has a slot fixed at the end away from the sleeve, a plug-in post is inserted into the slot, and a support plate is fixed on the outer wall of the plug-in post.
[0015] Furthermore, two sliders are provided on the outer wall of the end of the support plate away from the inner tube, and an adjustment plate is fixed between the two sliders. The adjustment plate has an inverted L-shaped structure, and an anti-slip pad is fixed on the end of each adjustment plate near the angle steel. A limit rod is also fixed on the outer wall of the support plate. An adjustment screw is connected to the internal thread of the limit rod, and the adjustment screw is rotatably connected to the bottom of the adjustment plate.
[0016] Furthermore, a conical indicator strip is fixedly provided on the outer wall of one end of each adjustment plate near the support plate, and a scale value is provided on the outer wall of the support plate, with the conical indicator strip facing the scale value.
[0017] Furthermore, a limiting block is fixedly connected to the outer wall of each inner tube in the circumferential direction, and a limiting groove is provided on the inner wall of each sleeve, with the limiting groove and the limiting block being inserted into each other.
[0018] The beneficial effects of this invention are:
[0019] 1. This invention, through the design of locking blocks, support blocks, two sleeves, two inner tubes, and two adjusting plates, eliminates the need for workers to assemble angle steel, steel base plates, and precast concrete on the ground. Instead, the steel base plate is first hoisted to the roof, and then several angle steels are assembled with the upper and lower ends of the steel base plate. Finally, concrete is poured at high altitude to complete the roof construction. Compared with existing technologies, this reduces the workload of workers, saves construction time, and thus helps to improve construction efficiency and shorten the construction cycle.
[0020] 2. This invention, through the design of a hemispherical buckle, inner rod, sleeve rod, and telescopic spring, allows for timely adjustment when workers discover misalignment between the bolt holes on the angle steel and the bolt holes on the steel base plate during angle steel installation. The inner tube slides inside the sleeve and is locked by the hemispherical buckle. This enables timely and flexible adjustment when deviations are detected, preventing construction errors, improving efficiency, avoiding material waste, and ultimately reducing construction costs.
[0021] 3. This invention designs four support plates, four adjusting screws, and adjusting plates, with the adjusting plates designed in an inverted L-shape. The outer wall of the adjusting plate can effectively fit against the outer wall of the angle steel. This allows workers to directly place the angle steel between the top of the two adjusting plates and the bottom of the steel base plate during installation. The adjusting screws then lift the angle steel until it fits against the bottom of the steel base plate, where it is finally secured with studs. Compared to existing technologies, this invention utilizes the support of the two adjusting plates during angle steel installation, eliminating the need for manual support and reducing worker fatigue. Furthermore, since this is a high-altitude operation, it saves worker effort and reduces potential safety hazards.
[0022] 4. This invention, through the design of a locking block, a support block, two sleeves, two inner tubes, and two adjusting plates, allows all the above-mentioned components to be quickly fixed through plug-in, threaded connection, and sleeve connection, thereby enabling rapid assembly with the steel base plate without delaying the overall process of roof assembly, thus improving the practicality of this roof.

[0034] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0035] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.
[0036] Reference Figures 1 to 9 The above describes a prefabricated box-shaped steel-concrete composite prefabricated roof system based on angle steel rib steel base plate 1. It includes a steel base plate 1 and a fixing mechanism 2. The fixing mechanism 2 includes a shielding component 3 and a fixing component 4. The shielding component 3 is symmetrically arranged at the bottom and top of the steel base plate 1, and the fixing component 4 is arranged on the shielding component 3.
[0037] The shielding component 3 includes four first angle steels 5 and four second angle steels 6. The four first angle steels 5 are symmetrically arranged at the bottom and top along the length of the steel base plate 1, and the four second angle steels 6 are symmetrically arranged at the bottom and top along the width of the steel base plate 1. Each second angle steel 6 has its two ends attached to the outer walls of two first angle steels 5 respectively. After the two first angle steels 5 and second angle steels 6 at the bottom of the steel base plate 1 are completely fixed, the other two first angle steels 5 and second angle steels 6 are fixedly connected to the top of the steel base plate 1 by studs 7. Finally, concrete is poured at the top and bottom ends of the assembled steel base plate 1 to facilitate the construction of the roof.
[0038] First Implementation Method
[0039] The fixing component 4 includes several bolts 7. Several bolt holes are evenly spaced on the outer wall of the steel base plate 1 in both the length and width directions. Each bolt 7 is inserted into a bolt hole. When the two first angle steels 5 are attached to the bottom of the steel base plate 1, the two first angle steels 5 are fixed by the bolts 7. Then, the two second angle steels 6 are fixedly connected to the bottom of the steel base plate 1 by the bolts 7, thereby realizing the fixed connection between the two first angle steels 5 and the second angle steels 6 and the bottom of the steel base plate 1.
[0040] A locking block 8 is fixed to the bottom of the steel base plate 1 by a first bolt. A rectangular through hole is opened on the locking block 8, and a support block 9 is inserted into the rectangular through hole. The support block 9 has a insertion hole, and the locking block 8 has a through hole. A second bolt is inserted into the insertion hole and the through hole. Before assembling the roof, the locking block 8 is first fixed to the bottom of the steel base plate 1 on the ground by the first bolt. Then, the support block 9 is inserted into the rectangular through hole in the locking block 8. Then, the second bolt is passed through the through hole and the insertion hole in sequence to lock the support block 9.
[0041] Second Implementation Method
[0042] Each side wall of the support block 9 is fixedly provided with a threaded sleeve 10, and a sleeve 11 is threadedly connected inside each threaded sleeve 10. An inner tube 12 is inserted inside the sleeve 11. Then the sleeve 11 is screwed into the inside of the threaded sleeve 10 to achieve a fixed connection between the sleeve 11 and the support block 9.
[0043] Each sleeve 11 has a fixed sleeve rod 13 on its outer wall. An inner rod 14 is inserted inside the sleeve rod 13, passing through the sleeve 11. A telescopic spring 15 is inserted between the inner rod 14 and the sleeve rod 13. A hemispherical buckle 16 is fixed at one end of the inner rod 14 near the inner tube 12. Several slots for the hemispherical buckles 16 to engage are evenly spaced on the outer wall of the inner tube 12. The inner tube 12 is then inserted into the sleeve 11. During insertion, the telescopic spring 15 contracts under force, thereby causing... The inner rod 14 retracts inside the sleeve rod 13. When the hemispherical buckle 16 slides into the slot, the telescopic spring 15 returns to its original position, thereby locking the inner tube 12 with the hemispherical buckle 16. This fixes the inner tube 12 to the sleeve 11. The inner tube 12 can slide flexibly inside the sleeve 11 and be locked by the hemispherical buckle 16. This allows for timely adjustment when there is a deviation between the bolt hole on the first angle steel 5 and the bolt hole on the steel base plate 1, thus facilitating assembly and improving assembly efficiency.
[0044] Each inner tube 12 is fixedly provided with a slot at the end away from the sleeve 11. A plug post 17 is inserted into the inside of the slot. A support plate 18 is fixedly provided on the outer wall of the plug post 17. After the inner tube 12 and the sleeve 11 are assembled, the support plate 18 is inserted into the end of the inner tube 12, and the plug post 17 is inserted into the inside of the slot, thereby fixing the support plate 18 and the inner tube 12.
[0045] Two sliders 19 are provided on the outer wall of the end of the support plate 18 away from the inner tube 12. An adjusting plate 20 is fixed between the two sliders 19. The adjusting plate 20 has an inverted L-shaped structure, and an anti-slip pad 21 is fixed on the end of each adjusting plate 20 near the angle steel. A limiting rod 22 is also fixed on the outer wall of the support plate 18. An adjusting screw 23 is internally threaded to the limiting rod 22. The adjusting screw 23 is rotatably connected to the bottom of the adjusting plate 20. When all the components at the bottom of the steel base plate 1 are assembled, the steel base plate 1 is first lifted by a lifting device. The base plate 1 is hoisted onto the roof beam. Workers stand on the scaffolding and then insert the first angle steel 5, which is hoisted along with it, between the two adjusting plates 20 and the bottom of the steel base plate 1. Then, by rotating the adjusting screw 23, since the adjusting screw 23 is rotatably connected to the adjusting plate 20, the adjusting plate 20 is slidably connected to the support plate 18, thereby driving the two adjusting plates 20 and the first angle steel 5 at the top to rise until they are in contact with the bottom of the steel base plate 1. The L-shaped structure of the adjusting plate 20 can support the angle steel, thereby improving the support effect.
[0046] Each adjusting plate 20 has a tapered indicator strip 24 fixed on the outer wall of one end near the support plate 18. The outer wall of the support plate 18 has a scale value 25, which can record the rising distance of the adjusting plate 20. This allows the worker to quickly and tightly attach the first angle steel 5 to the bottom plate of the steel base plate 1 when adjusting it again, thus speeding up the assembly process and improving assembly efficiency.
[0047] Each inner tube 12 has a limiting block 26 fixedly connected to its outer wall in the circumferential direction, and each sleeve 11 has a limiting groove on its inner wall. The limiting groove is inserted into the limiting block 26, and the limiting block 26 is inserted into the limiting groove, so that the inner tube 12 and the sleeve 11 are accurately inserted and the limiting function is achieved.
[0048] The working principle of this invention is as follows: Before assembling the roof, the locking block 8 is first fixed to the bottom of the steel base plate 1 on the ground by the first bolt. Then, the support block 9 is inserted into the rectangular through hole in the locking block 8. Then, the second bolt passes through the through hole and the insertion hole in sequence to lock the support block 9. Then, the sleeve 11 is screwed into the inside of the threaded sleeve 10 to realize the fixed connection between the sleeve 11 and the support block 9.
[0049] Then, the inner tube 12 is inserted into the sleeve 11. When inserted, the telescopic spring 15 is compressed, which causes the inner rod 14 to contract inside the sleeve rod 13. When the hemispherical buckle 16 slides into the slot, the telescopic spring 15 returns to its original position, which causes the hemispherical buckle 16 to lock the inner tube 12, thus fixing the inner tube 12 to the sleeve 11. The inner tube 12 can slide flexibly inside the sleeve 11 and be locked by the hemispherical buckle 16. This allows for timely adjustment when there is a deviation between the bolt hole on the first angle steel 5 and the bolt hole on the steel base plate 1, which facilitates assembly and improves assembly efficiency.
[0050] After the inner tube 12 and the sleeve 11 are assembled, the support plate 18 is inserted into the end of the inner tube 12, and the plug post 17 is inserted into the inside of the slot, thereby fixing the support plate 18 and the inner tube 12.
[0051] Once all components at the bottom of the steel base plate 1 are assembled, the steel base plate 1 is hoisted onto the roof beam using a lifting device. Workers stand on scaffolding, and then the first angle steel 5, which is hoisted along with it, is inserted between the two adjusting plates 20 and the bottom of the steel base plate 1. Next, by rotating the adjusting screw 23, which is rotatably connected to the adjusting plate 20, the adjusting plate 20 is slidably connected to the support plate 18, thereby causing the two adjusting plates 20 and the first angle steel 5 at the top to rise until they are in contact with the bottom of the steel base plate 1. The L-shaped structure of the adjusting plate 20 can support the angle steel, thereby improving the support effect. The scale value 25 can record the rising distance of the adjusting plate 20, so that when the workers adjust the first angle steel 5 again, they can quickly achieve a tight fit with the bottom plate of the steel base plate 1, speeding up the assembly process and improving assembly efficiency. The limiting block 26 and the limiting groove are inserted, so that the inner tube 12 and the sleeve 11 are accurately inserted, playing a limiting role.
[0052] After the two first angle steels 5 are attached to the bottom of the steel base plate 1, they are fixed with studs 7. Then, the two second angle steels 6 are fixedly connected to the bottom of the steel base plate 1 with studs 7, thus achieving a fixed connection between the two first angle steels 5 and the second angle steels 6 and the bottom of the steel base plate 1. After the two first angle steels 5 and the second angle steels 6 at the bottom of the steel base plate 1 are completely fixed, the other two first angle steels 5 and the second angle steels 6 are fixedly connected to the top of the steel base plate 1 with studs 7. Finally, concrete is poured at the top and bottom ends of the assembled steel base plate 1 to facilitate the construction of the roof.
