Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a steel reinforcement yard layout structure suitable for narrow and long plots of land. Background Technology

[0002] The steel reinforcement processing shed adopts frequency-modulated seamless welding technology, ensuring flawless welds. It boasts excellent resistance, being abrasion-resistant, rain-proof, and anti-aging. It offers high flexibility, allowing for disassembly and reuse after project completion. It features separation, barrier, and warning functions. Applications include safety protection at elevator shafts and edge areas on construction sites, as well as widespread use in power distribution maintenance, electrical maintenance, renovation construction, traffic control, company warning lines, and other restricted areas. Foundation pit safety fencing is an essential protective facility for preventing personal injury on construction sites. Suitable for safety protection at all types of construction sites, its conspicuous color markings serve as early warnings to workers of dangerous areas, making it an indispensable construction safety net for all construction sites.

[0003] The existing steel reinforcement sheds require workers to weld the supporting frame together before constructing the shed. This method results in sheds with poor stability and low construction efficiency, especially when constructing in narrow spaces. The limited space makes it difficult to bring in materials and hinders worker work. Furthermore, disassembly is inconvenient when the shed is removed from the factory, severely impacting construction efficiency.

[0004] Therefore, a rebar layout structure and installation method suitable for narrow and elongated plots are proposed. Utility Model Content

A motor is fixedly installed at the left end of the interior of the fixed base. An output shaft is provided at the right end of the motor. A fixing mechanism is provided on the right side of the output shaft. An extension mechanism is provided on the upper side of the fixed base. The fixing mechanism includes a threaded rod 1 fixedly installed at the right end of the motor's output shaft. The threaded rod 1 is a bidirectional threaded rod. A worm gear is fixedly installed at the right end of the threaded rod 1. A threaded rod 1 is fixedly installed at the right end of the worm gear. Threaded sleeve 1 is helically connected to the left side of the outer surface of two sets of threaded rod 1. A connecting rod 1 is rotatably connected to the front and rear sides of the outer surface of threaded sleeve 1. Threaded sleeve 2 is helically connected to the right side of the outer surface of threaded rod 1. A connecting rod 2 is rotatably connected to the front and rear sides of the outer surface of threaded sleeve 2. Fixed columns are fixedly installed at the four corners of the lower end face of the fixed base. The lower end face of the precast base has slots corresponding to the fixed columns.

[0008] Preferably, each of the two sets of threaded rods has a top block on its front and rear sides, and the connecting rod one and connecting rod two are rotatably connected to the corresponding top block one.

[0009] Preferably, a rod is fixedly installed on the outer side of the top block, and a slot is provided on the inner wall of the prefabricated base corresponding to the rod.

[0010] Preferably, the extension mechanism includes a threaded rod two provided on both the front and rear sides of the worm, and a gear is fixedly installed on the lower side of the outer surface of the threaded rod two, and the gear meshes with the worm.

[0011] Preferably, the threaded rod two is a bidirectional threaded rod, and a threaded sleeve three is helically connected to the lower side of the outer surface of the threaded rod two. A connecting rod three is rotatably connected to the left and right sides of the outer surface of the threaded sleeve three. A threaded sleeve four is helically connected to the upper side of the outer surface of the threaded rod two, and a connecting rod four is rotatably connected to the left and right sides of the outer surface of the threaded sleeve four.

[0012] Preferably, a top block 2 is provided on both the left and right sides of the threaded rod 2, and both the connecting rod 1 and the connecting rod 2 are rotatably connected to the corresponding top block 2.

[0013] Preferably, a support rod is fixedly installed on the left end of the top block, a slider is fixedly installed on the lower side of the support rod, and a slide rail is provided on the upper end of the fixed seat corresponding to the slider, and the slider is slidably connected inside the slide rail.

[0014] Preferably, a protective shell is provided on the upper side of the threaded rod 2, the threaded rod 2 is rotatably connected to the protective shell, and an extension canopy is slidably connected to the left and right sides inside the protective shell. A sliding groove is provided at the lower end of the protective shell, and the support rod is fixedly connected to the extension canopy through the sliding groove.

[0015] The beneficial effects of this utility model are:

[0016] This application employs a fixed mechanism. First, precast concrete is poured on the site as indicated. After the precast base solidifies, hoisting equipment is used to lift the fixed base, inserting the fixing column into the slot on the precast base. Then, the fixed base is lowered, and the motor is started. The motor's output shaft rotates the threaded rod and worm gear. As the threaded rod rotates, the threaded sleeves 1 and 2, which are helically connected on the left and right sides of the outer surface of the threaded rod, move towards each other. The threaded sleeve 1 moves the connecting rod 1, and the threaded sleeve 2 moves the connecting rod 2. Both connecting rods 1 and 2 are rotatably connected to a corresponding set of top blocks 1. Therefore, with the cooperation of connecting rods 1 and 2, the top blocks 1 are pushed outward. The top blocks 1 push the insert rod out of the fixed base and insert it into the slot on the precast base, thus completing the fixed installation of the fixed base. The installation is performed automatically by using pre-set equipment off-site and then by starting the motor, eliminating the need for manual installation and avoiding the problem of inconvenient installation of equipment in narrow sites.

[0017] This application incorporates an extension mechanism where the worm gear is meshed with the gear on the threaded rod 2. Therefore, when the worm gear rotates, the threaded rod 2 rotates synchronously. The threaded sleeves 3 and 4, which are helically connected on the outer surface of the threaded rod 2, move towards each other. The threaded sleeve 3 carries the connecting rod 3, and the threaded sleeve 4 carries the connecting rod 4. Both connecting rods 3 and 4 are rotatably connected to the top block 2, thereby pushing the top block 2 to move to both sides and pushing the two sets of support rods to move to both sides. As the support rods move, they drive the extension canopy to extend out from inside the protective shell, thus unfolding the steel reinforcement canopy. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The embodiments described below are only some embodiments of the present utility model, and not all embodiments.

[0028] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] Reference Figure 1-7 A rebar yard layout structure suitable for narrow and elongated plots includes a precast base 1, a fixed base 2 on the upper side of the precast base 1, a motor 3 fixedly installed at the left end of the interior of the fixed base 2, an output shaft at the right end of the motor 3, a fixing mechanism on the right side of the output shaft, and an extension mechanism on the upper side of the fixed base 2. The fixing mechanism includes a threaded rod 4 fixedly installed at the right end of the output shaft of the motor 3, the threaded rod 4 being a bidirectional threaded rod, a worm gear 14 fixedly installed at the right end of the threaded rod 4, and a threaded rod 4 fixedly installed at the right end of the worm gear 14. A threaded sleeve 5 is helically connected to the left side of the outer surfaces of the two sets of threaded rods 4. The outer front and rear sides of the threaded sleeve 5 are rotatably connected to the connecting rod 6. The outer right side of the threaded rod 4 is helically connected to the threaded sleeve 7. The outer front and rear sides of the threaded sleeve 7 are rotatably connected to the connecting rod 8. The four corners of the lower end face of the fixed seat 2 are fixedly installed with the fixing post 12. The lower end face of the precast seat 1 is provided with a slot 13 corresponding to the fixing post 12. The front and rear sides of the two sets of threaded rods 4 are provided with the top block 9. The connecting rod 6 and the connecting rod 8 are rotatably connected to the corresponding top block 9. The outer side of the top block 9 is fixedly installed with the insertion rod 10. The inner wall of the precast seat 1 is provided with a slot 11 corresponding to the insertion rod 10.

[0030] Specifically, existing steel reinforcement sheds require workers to weld the supporting frame together before constructing the shed. This method results in poor stability, low construction efficiency, and difficulty in disassembly upon return to the factory, severely impacting construction efficiency. Therefore, this application addresses the shortcomings of existing solutions by incorporating a fixing mechanism and an extension mechanism. Specifically: First, precast base 1 is poured with concrete according to the site plan. After the precast base 1 solidifies, a hoisting device is used to lift the fixing base 2, inserting the fixing column 12 on the fixing base 2 into the slot 13 on the precast base 1. Then, the fixing base 2 is lowered, and the process begins. Motor 3 causes the output shaft of motor 3 to rotate threaded rod 4 and worm gear 14. When threaded rod 4 rotates, threaded sleeve 5 and threaded sleeve 7, which are helically connected on the left and right sides of the outer surface of threaded rod 4, will move towards each other. Threaded sleeve 5 will move connecting rod 6, and threaded sleeve 7 will move connecting rod 8. Both connecting rod 6 and connecting rod 8 are rotatably connected to a corresponding set of top blocks 9. Therefore, with the cooperation of connecting rod 6 and connecting rod 8, the top blocks 9 are pushed to move outward. The top blocks 9 will push the insert rod 10 to extend out of the inside of the fixed seat 2 and insert it into the slot 11 on the prefabricated seat 1, thereby completing the fixed installation of the fixed seat 2.

[0031] As shown in the figure, the extension mechanism includes a threaded rod 16 on both the front and rear sides of the worm 14. A gear 15 is fixedly installed on the lower outer surface of the threaded rod 16, and the gear 15 meshes with the worm 14. The threaded rod 16 is a bidirectional threaded rod. A threaded sleeve 17 is helically connected to the lower outer surface of the threaded rod 16. A connecting rod 18 is rotatably connected to the left and right sides of the outer surface of the threaded sleeve 17. A threaded sleeve 19 is helically connected to the upper outer surface of the threaded rod 16. A connecting rod 20 is rotatably connected to the left and right sides of the outer surface of the threaded sleeve 19. A top is provided on both the left and right sides of the threaded rod 16. Block 21, connecting rod 1 6 and connecting rod 2 8 are rotatably connected to the corresponding top block 21. A support rod 22 is fixedly installed on the left end of the top block 21. A slider 23 is fixedly installed on the lower side of the support rod 22. A slide rail 24 is opened on the upper end of the fixed seat 2 corresponding to the slider 23. The slider 23 is slidably connected inside the slide rail 24. A protective shell 25 is provided on the upper side of the threaded rod 2 16. The threaded rod 2 16 is rotatably connected to the protective shell 25. An extension canopy 26 is slidably connected on the left and right sides inside the protective shell 25. A groove 27 is opened at the lower end of the protective shell 25. The support rod 22 is fixedly connected to the extension canopy 26 through the groove 27.

[0032] Specifically, the worm gear 14 is in a meshing transmission state with the gear 15 on the threaded rod 16. Therefore, when the worm gear 14 rotates, the threaded rod 16 rotates synchronously. The threaded sleeves 17 and 19, which are helically connected on the outer surface of the threaded rod 16, will move towards each other. The threaded sleeve 17 carries the connecting rod 18 to move, and the threaded sleeve 19 carries the connecting rod 20 to move. Both the connecting rod 18 and the connecting rod 20 are rotatably connected to the top block 21, thereby pushing the top block 21 to move to both sides and pushing the two sets of support rods 22 to move to both sides. At the same time as the support rods 22 move, they will drive the extension canopy 26 to extend out from the inside of the protective shell 25, thereby unfolding the steel reinforcement canopy.

[0033] A method for installing rebar in a narrow, elongated plot of land, comprising the following steps:

[0034] S1: Hoisting and fixing: First, use concrete to pour the precast base 1 at the construction site. After the precast base 1 has solidified, use hoisting equipment to hoist the fixing base 2 so that the fixing column 12 on the fixing base 2 is aligned with the groove 13 on the precast base 1, so that the fixing column 12 is inserted into the inside of the groove 13 for fixing and installation.

[0035] S2: Extension Fixing: By starting the motor 3, the output shaft of the motor 3 carries two sets of threaded rods 4 to rotate. The rotation of the threaded rods 4 drives the threaded sleeves 5 and 7 to move towards each other. Under the cooperation of the connecting rods 6 and 8, the top block 9 is driven to push the insert rod 10 out of the inside of the fixed seat 2 and insert it into the inside of the slot 11, thereby completing the fixing operation.

[0036] S3: Extension and Deployment: When the starting threaded rod 4 rotates, the worm gear 14 rotates synchronously to transmit power to the extension mechanism, causing the support rod 22 to carry the extension canopy 26 to unfold, expanding the area of ​​the steel reinforcement canopy. When not in use, the reverse motor 3 can be reversed to retract the steel reinforcement canopy, reducing the usable space of the steel reinforcement canopy.

[0037] In use of this utility model, firstly, precast base 1 is poured with concrete on the site. After the precast base 1 solidifies, a hoisting device is used to hoist the fixed base 2, so that the fixing column 12 on the fixed base 2 is inserted into the slot 13 on the precast base 1. Then, the fixed base 2 is lowered, and the motor 3 is started, causing the output shaft of the motor 3 to rotate the threaded rod 4 and worm gear 14. As the threaded rod 4 rotates, the threaded sleeves 5 and 7, which are helically connected on the left and right sides of the outer surface of the threaded rod 4, move towards each other. The threaded sleeve 5 carries the connecting rod 6, and the threaded sleeve 7 carries the connecting rod 8. Both connecting rods 6 and 8 are rotatably connected to a corresponding set of top blocks 9. Therefore, with the cooperation of connecting rods 6 and 8, the top blocks 9 are pushed outwards. The push rod 10 extends out from the inside of the fixed base 2 and is inserted into the slot 11 on the precast base 1, thereby completing the fixed installation of the fixed base 2. Next, the worm gear 14 is in a meshing transmission state with the gear 15 on the threaded rod 16. Therefore, when the worm gear 14 rotates, the threaded rod 16 rotates synchronously. The threaded sleeves 17 and 19, which are helically connected on the outer surface of the threaded rod 16, will move towards each other. The threaded sleeve 17 carries the connecting rod 18 to move, and the threaded sleeve 19 carries the connecting rod 20 to move. The connecting rods 18 and 20 are rotatably connected to the top block 21, thereby pushing the top block 21 to move to both sides and pushing the two sets of support rods 22 to move to both sides. While the support rods 22 are moving, they will drive the extension canopy 26 to extend out from the inside of the protective shell 25, thereby unfolding the steel reinforcement canopy.
