an adjustable strip-type plate surface negative rib protective layer thickness control device comprises a hollow transverse square steel; the upper surface of the square steel is a concrete pouring completion surface, and the lower surface is a connecting surface; the connecting surface is provided with two symmetrically arranged bolt holes for accommodating bolts; one end of the bolt sequentially passes through the first nut and the bolt hole adjacent to the first nut and then is locked with the second nut, and the other end of the bolt is fixedly connected with the middle part of a bottom plate; the two ends of each bottom plate are fastened with the template through screws in a threaded manner; two through holes corresponding to the positions of the bolt holes and convenient for taking and placing the second nuts are formed in the concrete pouring completion surface.
Further, the bottom plate is perpendicular to the square steel.
Further, the through holes are concentrically arranged with the adjacent bolt holes; the diameter of the through hole is larger than that of the bolt hole.
Further, the bolts are welded with the bottom plate.
Further, the screws pass through the bottom plate to fix the screws on the template.
The utility model has the following beneficial effects:
1. according to the utility model, the bottom plate and the template are fastened through screw threads, so that the square steel is fastened with the screw threads on the bottom plate, the effect of improving the connection stability of the square steel and the template is achieved, and the concrete pouring effect is not easily influenced by displacement and dumping in the construction process; through the through holes arranged on the concrete pouring completion surface of the square steel, the second nut is convenient to take and place, and the lower through holes of the connection surface are matched with the first nut and the second nut, so that the adjustment of the height of the square steel and the control of the thickness of the protective layer are realized; the square steel is fastened with the screw threads of the bolts on the bottom plate, so that the square steel is conveniently taken down for reuse before concrete pouring and initial setting are completed.

Detailed Description
The utility model will now be described in detail with reference to the drawings and to specific embodiments.
Referring to fig. 1-3, an adjustable strip plate surface negative rib protective layer thickness control device comprises a hollow transverse square steel 1; the upper surface of the square steel 1 is a concrete pouring finished surface 11, and the lower surface is a connecting surface 12; the connecting surface 12 is provided with two symmetrically arranged bolt holes 13 for accommodating the bolts 2; one end of the bolt 2 sequentially passes through the first nut 3 and the bolt hole 13 adjacent to the first nut and then is locked with the second nut 3', and the other end of the bolt 2 is fixedly connected with the middle part of a bottom plate 4; both ends of each bottom plate 4 are fastened with the templates 6 through screws 5 in a threaded manner; two through holes 14 corresponding to the positions of the bolt holes 13 and facilitating the taking and placing of the second nuts 3' are formed in the concrete pouring completion surface 11.
Further, the bottom plate 4 is perpendicular to the square steel 1.
Further, the through hole 14 is concentrically arranged with the adjacent bolt hole 13; the diameter of the through hole 14 is larger than the diameter of the bolt hole 13.
Further, the bolts 2 are welded to the bottom plate 4.
Further, the screws 5 pass through the bottom plate 4 to fix it to the form 6.
The working principle of the utility model is as follows:
referring to fig. 1-3, before pouring concrete, a plurality of utility models are arranged on a template 6 provided with a plate surface negative rib 7 at intervals, so that the utility models are close to the plate surface negative rib 7, and each of the utility models is arranged in the following way: two bottom plates 4 are arranged below the connecting surface 12 of the square steel 1, bolts 2 on the two bottom plates 4 are aligned with bolt holes 13 on the adjacent connecting surface 12 respectively, and screws 5 are arranged at two ends of each bottom plate 4, so that the screws 5 penetrate through the bottom plates and then are fixed on the templates 6; through adjusting the height of square steel 1 on bolt 2, make the concrete placement of square steel 1 accomplish face 11 keep in the position that highly is 15mm with face negative muscle 7 between, make the one end that bolt 2 kept away from bottom plate 4 pass first nut 3 in proper order, screw-fastening with second nut 3' behind the bolt hole 13 adjacent to it, can accomplish the fixed connection between bottom plate 4 and template 6, between bottom plate 4 and the square steel 1, in order to improve the steadiness of square steel 1, can carry out concrete placement afterwards, make it flush with concrete placement accomplish face 11, realize the control to protective layer thickness.
