Clamping structure for H-shaped steel structure production

Abstract

The clamping structure for H-shaped steel structure production comprises a base plate, a driving assembly and a clamping plate, a through groove is formed in one side of the clamping plate, a threaded column is connected to the inner wall of the through groove in a sliding mode, a supporting plate is connected to one end of the threaded column in a rotating mode, a threaded sleeve is connected to the outer wall of the threaded column through threads, and the threaded sleeve is connected to the driving assembly. And the supporting plate is fixed with the clamping plate through a fastener. According to the H-shaped steel clamping device, when H-shaped steel is placed on the base plate to be clamped, a worker adjusts the positions of the two supporting plates according to the thickness of a flange plate of the H-shaped steel and the height of a web plate, then the worker rotates a threaded column through a grip, the threaded column enables a threaded sleeve to move to extrude a friction ring, and then the H-shaped steel is clamped. The friction ring can increase the friction force with the clamping plate to fix the supporting plate at the designated height, then the worker moves the movable plate to insert the clamping column into the clamping groove through the spring, and therefore the limiting block can be positioned to enable the threaded sleeve not to move horizontally.

Description

Technical Field

[0001] The utility model relates to the technical field of H-shaped steel, in particular to a clamping structure for producing H-shaped steel structures. Background Art

[0002] H-shaped steel is an economical and efficient profile with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H". Since all parts of the H-shaped steel are arranged at right angles, it has the advantages of strong bending resistance in all directions, simple construction, cost savings and light structural weight, and has been widely used.

[0003] The existing clamping structure used in the production of H-shaped steel structures can only clamp and fix H-shaped steel of a single specification. When facing H-shaped steels of different specifications, the existing clamping mechanism cannot effectively support the gap between the web and flange of the H-shaped steel. This will cause the flange to be squeezed and deformed due to lack of support during the processing of the H-shaped steel. Utility Model Content

[0004] The purpose of the utility model is to solve the above problems and to provide a clamping structure for producing H-shaped steel structures.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A clamping structure for producing H-shaped steel structures includes a base plate, a driving assembly and a clamping plate, a through groove is opened on one side of the clamping plate, a threaded column is slidably connected to the inner wall of the through groove, one end of the threaded column is rotatably connected to a support plate, the outer wall of the threaded column is connected to a threaded sleeve via a thread, and the support plate is fixed to the clamping plate via a fastener.

[0007] Preferably, the fastener comprises a friction ring, a protrusion is fixedly connected to the outer wall of the threaded sleeve, and a limiting block is fixedly connected to one side of the protrusion.

[0008] Preferably, a slot is provided on one side of the limit block, a movable active plate is installed on the clamping plate, a clamping column is slidably connected to the inner wall of the movable plate, one end of the clamping column is fixedly connected to a push plate, and one side of the push plate is fixedly connected to a spring.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0012] In the present application, when the H-shaped steel is placed on the base plate for clamping, the staff adjusts the positions of the two support plates according to the thickness of the H-shaped steel flange plate and the height with the web plate. Then the staff rotates the threaded column through the handle, and the threaded column will cause the threaded sleeve to move and squeeze the friction ring. The friction ring will increase the friction with the clamping plate to fix the support plate at a specified height. Then the staff moves the movable plate to insert the clamping column into the clamping slot through the spring, so that the limit block can be positioned so that the threaded sleeve cannot move horizontally.
