Problems solved by technology

This fixing method cannot meet the accuracy requirements of one-time construction on high-flatness ground. First, the steel and the tripod are independent of each other, and there is no fixed connection method; second, the height of the tripod is fixed. When the elevations of the points are different, only the measure of adding cushions at the foot of the bracket can be taken; third, the support of the tripod bracket is unstable, and it will fall down under mechanical vibration.

Embodiment Construction

[0012] The fixed and height-adjustable rail support structure for controlling the thickness of paving cast-in-place concrete of the present invention will be described in conjunction with the accompanying drawings and embodiments.

[0013] The fixed and adjustable height rail support for controlling the thickness of cast-in-place concrete ground paving according to the present invention, the rail support is arranged under the shaped steel track to support and fix the shaped steel track, and adjust the height of the shaped steel track. The rail support includes a belt wire Buckle legs 6, beams 9, adjustable nuts 4, steel gaskets 5, fastening nuts 3; the two ends of the beams 9 are respectively fixedly connected with thread buckle legs 6, forming H-shaped brackets with the beams 9, two straps The lower end of the threaded support foot 6 passes through the adjustable nut 4 and the steel washer 5, and the lower ends of the two support feet go deep into the preset hole 8; The lug p...

Abstract

The invention provides a fixed height-adjustable steel rail support capable of controlling the paving thickness of cast-in-situ concrete, and the steel rail support comprises support legs with screw threads, wherein the support legs with the screw threads are fixedly connected at two ends of a cross beam respectively so as to form an H-shaped support with the cross beam, the lower ends of the twosupport legs with the screw threads penetrate through adjustable nuts and steel gaskets, and the lower ends of the two support legs are deeply arranged in preset holes; and fastening nuts are arranged at the upper ends of the two support legs with the screw threads respectively, and lug plates on the two sides of a section steel rail are compressed and fixed respectively for closely fixing the section steel rail with the cross beam. The fixed height-adjustable steel rail support has the benefits that the height of the steel rail support per se can be regulated precisely, the effect of adjusting the height of the section steel is achieved, the height-adjustable support and the section steel can be prevented from moving in the horizontal direction, the section steel rail and the height-adjustable support are fastened into a whole, and after the process steps of paving the concrete and leveling the concrete are completed, the height-adjustable support and the section steel rail can be folded together and used repeatedly. The scale height and the levelness of the unilateral section steel rail, as well as the relative levelness of the two rails, can be adjusted, and the final precisioncan be within 1mm.

Description

technical field [0001] The invention relates to a concrete paving thickness and flatness control device for a large-area wear-resistant cast-in-place concrete floor in one-time forming construction technology in building construction, in particular to a fixed and height-adjustable steel rail support for controlling the thickness of paving cast-in-place concrete. Background technique [0002] In general building construction, the concrete paving and leveling process of large-area wear-resistant concrete floor construction adopts mechanical paving and leveling technology, and the concrete paving thickness and leveling accuracy depend on the two sides of the paving and leveling equipment The profiled steel track is controlled, so the concrete thickness and leveling accuracy depend on the overall leveling accuracy of the two profiled steel tracks. [0003] The concrete ground surface layer constructed by traditional technology cannot be used as the final surface layer because it...
