Description

Technical Field

[0001] This utility model relates to the field of floor slab construction, and in particular to a truss-type support platform for floor slabs. Background Technology

[0002] For example, Chinese Utility Model Patent Publication No. CN 201794297 U discloses an early-stripping formwork support system for cast-in-place ribbed slabs with large spans. This system includes beam formwork, ribbed slab formwork, trusses, and supports, as well as adjustable supports under the beams. These adjustable supports are removed after the supports, trusses, beam formwork, and ribbed slab formwork. The supports include beam formwork supports, support rods, and support columns. The ribbed slab formwork includes profiled steel formwork and grating. The ribbed slab formwork is laid on the trusses, with the ends of the profiled steel formwork located at the top of the beam formwork. A plug is provided between the ends of the profiled steel formwork and the top of the beam formwork. The trusses used primarily serve to support the bottom formwork of the slab and are not converted into unit platforms, making disassembly and relocation inconvenient. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a truss-type support platform for floor slabs, which can stably support and disassemble planar formwork, such as the bottom formwork of the slab, and is also convenient for transporting planar formwork together, so that the planar formwork can be divided into unit grids, which is conducive to improving construction efficiency.

[0004] To solve the above problems, a floor slab truss support platform was adopted, which includes:

[0005] Truss beams, which are arranged in both longitudinal and transverse directions, form a frame grid structure;

[0006] A portal frame, spaced apart in a grid, is fixed on both sides to a truss beam. It has an upper U-shaped frame and a lower U-shaped frame. The lower U-shaped frame has lower uprights on both sides and is fixed to the truss beam. The lower ends of the upper uprights on both sides of the upper U-shaped frame slide into the lower uprights of the lower U-shaped frame.

[0007] The hydraulic jack is installed on the bottom beam of the lower U-shaped frame, and its piston head is installed on the top beam of the upper U-shaped frame.

[0008] The conversion beam is installed on the bottom beam of the lower U-shaped frame and is located on one side of the hydraulic jack.

[0009] The pad beam is installed on the lower chord of the truss beam and fixed under the transfer beam;

[0010] The lifting lugs are installed on the transfer beam;

[0011] Adjusting sleeve, which is fixed to the middle node of the scissor brace on the front and rear sides of the truss beam;

[0012] The adjusting ring has a threaded section and a ring head fixed at one end of the threaded section, and the threaded section is threadedly connected to the adjusting sleeve.

[0013] The pull rope is installed between the adjusting ring and the lifting lug.

[0014] With this structure, the portal frame is used to support the bottom formwork of the slab; the portal frame is raised and lowered by hydraulic jacks, which facilitates the support and disassembly of the bottom formwork of the slab; when the hydraulic jacks apply force, the bottom beam of the lower U-shaped frame is subjected to a reaction force, which is transmitted to the pull rope by the conversion beam; by adjusting the threaded section of the pull ring into the adjusting sleeve, the pull rope is tightened to prevent the bottom beam of the lower U-shaped frame from deflecting, so as to ensure that the hydraulic jacks stably support the portal frame.

[0015] As a further improvement of this utility model, angle steel is fixed on the four branch rods of the scissor brace, and the angle steel is fixed around the adjusting sleeve.

[0016] This structure provides stable support for the adjusting sleeve and strengthens the connection between the adjusting sleeve and the scissor brace.

[0017] As a further improvement of this utility model, reinforcing ribs are provided on the angle steel.

[0018] This structure is used to improve the overall rigidity of the angle steel.

[0019] As a further improvement of this utility model, a ring sleeve is provided at the bottom of the ring head and is slidably sleeved on the threaded section, and a limiting screw head is provided at one end of the threaded section that extends out of the ring sleeve.

[0020] With this structure, when the limiting screw head rotates, the ring sleeve slides on the threaded section, so the ring head will not rotate. This means that the pull rope will only be subjected to tension, and will not exert a reaction force on the threaded section due to torsion, thus preventing the threaded section from reversing.

[0021] As a further improvement of this utility model, the lifting lug and the conversion beam, as well as the conversion beam and the bottom beam of the lower U-shaped frame, are connected by a bolt and nut assembly.

[0022] This structure allows for a tighter connection between the various components.

[0023] As a further improvement of this utility model, the top beams of the upper U-shaped frame in a grid are fixed together by horizontal bars, which fix the middle and both ends respectively.

[0024] This structure facilitates the formation of a planar frame from the top beam of the portal frame.

[0025] As a further improvement of this utility model, the lower end of the upper upright tube of the upper U-shaped frame and the upper end of the lower upright tube of the lower U-shaped frame are provided with pin holes and are adapted to be fitted with pins.

[0026] With this structure, when the upper U-shaped frame is fully extended, the lower end of the upper upright tube of the upper U-shaped frame and the upper end of the lower upright tube of the lower U-shaped frame can be locked with a pin. When the upper U-shaped frame needs to be retracted, the pin can be pulled out and the lock released.

[0027] As a further improvement of this utility model, a sliding trolley is provided at the bottom of the truss beam.

[0028] With this structure, the sliding trolley can easily move along the track to support the truss structure.

[0029] This invention can stably support and disassemble planar templates, such as bottom templates, and is also convenient for transporting planar templates together. It allows the planar templates to be divided into unit grids, which helps to improve construction efficiency. Attached Figure Description

[0054] With this structure, the portal frame 2 is used to support the bottom formwork of the slab; the portal frame 2 is controlled by hydraulic jacks 3 to raise and lower, which facilitates the support and disassembly of the bottom formwork of the slab; when the hydraulic jacks 3 apply force, the bottom beam of the lower U-shaped frame 202 is subjected to a reaction force, which is transferred to the pull rope 9 by the conversion beam 4. The pull rope 9 is tightened by adjusting the threaded section 801 of the pull ring 8 into the adjusting sleeve 7 to prevent the bottom beam of the lower U-shaped frame 202 from deflecting, so as to ensure that the hydraulic jacks 3 stably support the portal frame 2; the upper and lower ends of the lower vertical tube of the lower U-shaped frame 202 are fixed to the inside of the truss beam by welding reinforced angle steel.

[0055] In this embodiment, angle steel 10 is fixed on the four branch rods of the scissor brace 101, and the angle steel 10 is fixed around the adjusting sleeve 7.
