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 two support 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 precision can be within 1mm.
Description
Technical field
The present invention relates to concrete speading thickness, the planeness control device of the wear-resisting cast-in-situ concrete terrace of large tracts of land once-molding construction process in the building operations, particularly control the fixedly adjustment height rail rest of the thickness of cast-in-place concrete that paves.
Background technology
In the common buildings construction, the concrete speading of large tracts of land abrasion-proof concrete floor construction and leveling operation are to adopt machinery to pave and levelling process, concrete paving thickness and leveling precision rely on the shaped steel track that paves with the levelling means both sides to control, therefore concrete thickness and leveling precision depend on the overall leveling precision of two shaped steel tracks.
The concrete surface surface layer of traditional handicraft construction, do not reach smooth precision and the aesthetics of finish coat because of its planeness, therefore can not be as final surface layer, must be aided with other coating ways, such as the final surface layer of the conducts such as Self-leveling, floor tile, stone material, according to " building floor engineering construction quality standards of acceptance " (GB50209-2002) requirement, surface evenness is not more than 3mm accurately.Its reason is exactly that the precision of shaped steel track does not reach requirement.Basic unit under the common indoor cast-in-situ concrete surface layer is the reinforced concrete structure surface layer, and the fixing means of shaped steel track in basic unit is to adopt A-frame to support so.This fixed form can not satisfy the required precision of the construction molding in high-flatness ground, at first, is separate between shaped steel and the A-frame, is not fixedly connected with mode; The second, the height of A-frame is certain, such as the absolute altitude of each point on the shaped steel not simultaneously, can only take the measure of cushioning under the stent foot; The 3rd, A-frame supports unstable, can lodge at mechanical shock.
Summary of the invention
For solving the problem that exists in the above-mentioned technology, the purpose of this invention is to provide pave the fixedly adjustment height rail rest of thickness of cast-in-place concrete of a kind of control, be beneficial to guarantee that large area concrete ground once paves, the planeness after smooth satisfies code requirement, the planeness of shaped steel track satisfies and is higher than code requirement, avoid the interference of mechanical shock, guarantee that the concrete pavement of once-cast has higher planeness.
For achieving the above object, the technical solution used in the present invention provides pave the fixedly adjustment height rail rest of thickness of cast-in-place concrete of a kind of control, this rail rest is located at below the shaped steel track, with rest and fixed steel track, and adjustment type steel track height, described rail rest includes band screw thread leg, crossbeam, adjustable nut, steel plate washer, clamp nut; Be fixedly connected with respectively band screw thread leg at the two ends of described crossbeam, form H type support with crossbeam, two pass adjustable nut and steel plate washer with the lower end of screw thread leg, and two leg lower ends are deeply in the default hole; Two upper ends with the screw thread leg are respectively equipped with clamp nut, and two clamp nuts are pressed abd fixed on respectively the otic placode of shaped steel track both sides, form the closely fixing of shaped steel track and crossbeam.
Effect of the present invention is this fixedly adjustment height rail rest, absolute altitude by the adjustable bolt regulation type steel track on the fixing adjustment height rail rest leg, and by regulate fixing adjustment height rail rest control type steel track about with the above-below direction displacement, have four aspect effects, the first, this support can precision regulating integer oneself height, reaches the effect of adjusting the shaped steel height, adopt thin button bolt to regulate height, precision can reach 0.5mm; The second, in the default hole of going down to the grass-roots units in this support lower end, can prevent from regulating the horizontal direction play of height bracket and shaped steel; The 3rd, the fastening bolt of this support leg upper end can compress the otic placode of shaped steel both sides, and making shaped steel and adjustable-height support fastening is an adult; The 4th, after concrete speading, smooth operation were finished, adjustable-height support and shaped steel track were together packed up, and reuse.By adjusting the adjusting bolt of each support, absolute altitude and the levelness of the one-sided shaped steel track of capable of regulating, and the relative level degree of two tracks, its final precision can reach in the 1mm.After the leveling of high-accuracy mechanical levelling means, can realize that concrete once-cast, leveling precision reach 3mm with interior effect.Surface layer can be removed other finish coat ways from after cure process, directly as final finished surface.
