Description

Technical Field

[0001] The utility model relates to the technical field of preventing T-beam cracking, in particular to a structure for preventing T-beam end heads from tensioning and cracking. Background Art

[0002] T-beam refers to a beam with a T-shaped cross section. The upper part is called the flange, and the middle part is called the beam rib (or web). Since it is equivalent to the concrete in the tensile area of ​​the rectangular beam that does not play a role in the bending strength, it has the same bending strength as the original rectangle, but it can save concrete, reduce the deadweight of the component, and improve the spanning capacity;

[0003] In the patent entitled "A structure for preventing tension cracking of T-beam ends" with the Chinese announcement number CN220202435U, a foam pad of polyethylene foam material with a length of 10-20 cm is set at the end of the T-beam block in the T-beam structure for preventing tension cracking of the T-beam end. The span of the foam pad is the same as the width of the T-beam bottom plate. During the tensioning process of the T-beam block end, the foam pad at the connection between the T-beam bottom plate and the T-beam block reduces the stress concentration at the bottom of the T-beam block, so that the stress of the T-beam block end is dispersed to most areas of the T-beam block end. At the same time, part of the stress of the T-beam block end is transferred to the inner side of the T-beam bottom plate, so as to achieve the purpose of reducing the tension damage of the T-beam block end, and will not affect the appearance quality and overall force performance of the beam plate;

[0004] However, this device still has some shortcomings. This mechanism uses two sets of fixing components to achieve the effect of limiting and fixing the T-beam block. However, since the installation position of the T-beam block is mostly at a higher place, workers are required to move the fixing components to both sides of the T-beam for installation, which makes the installation process have certain safety hazards. At the same time, after the two sets of fixing components are installed on both sides of the T-beam, workers are required to complete the work of limiting the two sets of fixing components by turning rods, thereby increasing the workload of workers. In view of the above problems, the inventor proposes a structure for preventing the tension cracking of the T-beam end to solve the above problems. Utility Model Content

A bottom block 36 is fixedly connected to the center of the bottom end of the plate groove 2 33, and the bottom block 36 is rotatably connected to the screw rod 2 38 through a thread.

[0022] One end of the side plate 37 away from the second screw rod 38 is fixedly connected to the second motor 39 , and the output end of the second motor 39 passes through the side plate 37 and is fixedly connected to the second screw rod 38 .

[0023] By adopting the above technical solution, the second motor 39 is operated, so that the second screw rod 38 which is fixedly connected is rotated.

[0024] Insertion rods 311 are symmetrically fixedly connected to both side ends of the second limiting plate 310 and near the center, and external threads are provided on the outer circle of the insertion rods 311 and near the first limiting plate 32.

[0025] By adopting the above technical solution, setting the insertion rod 311 and opening the external thread, and matching the corresponding bolts and the insertion plate 312, the effect of fixing the distance between the limiting plate 1 32 and the limiting plate 2 310 is achieved.

[0036] Working principle: When the present device is used, firstly, the limit plate 1 32 and the limit plate 2 310 are placed in the plate groove 1 31 and the plate groove 2 33 respectively, and then the motor 1 23 is operated to rotate the screw rod 1 21 fixedly connected, so that the lifting plate 24 connected by the threaded rotation is lifted under the action of the straight beam 2, and then, with the cooperation of the base 3, the limit plate 1 32 and the limit plate 2 310 are lifted to the T beam, thereby solving the problem that the workers need to move the fixed components to both sides of the T beam for installation because the installation position of the T beam block is mostly at a higher place, which makes the installation process have certain safety hazards;

[0037] Then, by running the motor 2 39, the screw rod 2 38 that is fixedly connected is rotated, so that the bottom block 36 that is rotatably connected by the thread, under the cooperation of the plate groove 2 33, the two rollers 34 and the rail groove 35, makes the plate groove 2 33 drive the limit plate 2 310 to move toward the limit plate 1 32, so that the limit plate 1 32 and the limit plate 2 310 are abutted against the two sides of the T beam, and the two insertion rods 311 are inserted into the inside of the insertion plate 312, thereby achieving the effect of limiting the T beam, thereby solving the problem that after the two sets of fixed components are installed on both sides of the T beam, the workers still need to complete the work of limiting the two sets of fixed components by turning the rod, which increases the workload of the workers.
