Anchoring-thickness-adjustable height-adjusting support

Abstract

The invention provides an anchoring-thickness-adjustable heightening support which comprises a support body, height-adjusting type anchoring bolts and common type anchoring bolts. The support body iscomposed of a beam bottom embedded plate, an upper base plate, a middle base plate and a lower base plate which are symmetrically arranged along the center line. Two upper anchoring holes used for installing the height-adjusting type anchoring bolts are formed in the edges of the two transverse sides of the upper flat plate respectively, a beam bottom pre-buried plate is arranged on the upper surface of the upper flat plate in an attached mode, and installing holes which correspond to the upper anchoring plates and are used for the height-adjusting type anchoring bolts to penetrate through areformed in the beam bottom pre-buried plate. Each height-adjusting type anchoring bolt comprises a sleeve, an anchor rod, an adjusting bolt, a deformation plate and a nut, the adjusting bolt is rotated to enable the deformation plate to press or leave the upper surface of the anchor rod, the deformation plate deforms to press or leave the inner wall of the sleeve, and pressing fixing or contracting loosening is achieved. The problems that an existing screw telescopic anchoring scheduling support is inconvenient to operate, and height adjustment fails due to thread stress deformation are solved, and the support is reliable in function, convenient to operate, large in height adjustment amount application range and good in economy.

Description

technical field [0001] The invention relates to the technical field of height-adjusting supports, in particular to a height-adjusting support with adjustable anchorage thickness. Background technique [0002] At present, there are 4 methods of height adjustment for backing plate, spiral height adjustment, wedge height adjustment and injection filling body height adjustment at home and abroad. The spiral height adjustment structure bears the force through the threaded pair, which is not suitable for occasions with high bearing capacity requirements; the bolts of the wedge to push the wedge in the center of the wedge are under a large force, the slope of the wedge should not be too large, and the amount of height adjustment is limited; filling The body height adjustment method is complicated to adjust, and the filling body takes a long time to cure; the backing plate height adjustment method is currently the most widely used and the easiest to operate. The backing plate heigh...

Problems solved by technology

[0003] In order to solve the above-mentioned technical problems, the present invention provides a height-adjustable support with adjustable anchorage thickness, which solves the problem that the existing general-purpose height-adjustment support has different heights due to different height adjustments and poor economic efficiency, and solves the problem that the existing screw telescopic anchor The operation of the dispatching support is inconvenient, and the deformation of the screw thread causes the failure of height adjustment. The support meets the requirements of reliable function, convenient operation, large adaptability of height adjustment, and good economy.
