Cushion block for controlling floor thickness

Abstract

The invention relates to a cushion block for controlling floor thickness. The cushion block for controlling floor thickness effectively overcomes the problems of great consumption of labor and energy and long construction period since the elevation and flatness of floors in construction are difficult to control and subsequent operation like making of a leveling layer is needed in the prior art. According to a technical scheme in the invention, a totally through hole is arranged in a concrete cushion block; a nut is embedded in the through hole; the nut is nested with the lower end of a bolt; the upper end of the bolt is arranged above the nut and coated with a reflecting paint layer; and a groove located at the outer side of the through hole is formed in the center of the top surface of the concrete cushion block. The cushion block for controlling floor thickness in the invention is simple in structure, low in manufacturing cost, practical and convenient; the height of the cushion block can be adjusted at will to fit floors with various thicknesses; floor thicknesses of both plane roofs and sloping roofs can be effectively guaranteed; and the elevation and flatness of cast-in-situ concrete slabs can be controlled in one shot, so the construction procedure for making a leveling layer for a floor is omitted.

Description

Technical field [0001] The invention relates to the field of construction, in particular to a floor slab thickness control pad. Background technique [0002] At present, during the construction of cast-in-place floor slabs, the elevation and flatness of the floor slabs are difficult to meet the design and specification requirements. Some use the mark elevation control on the reserved steel bars, and some draw the elevation line control, but due to the operator’s arbitrariness and The different levels of operation technology ultimately lead to difficult control. During the quality acceptance and construction of the next process, the quality problems of the pouring floor elevation and flatness will be exposed. In order to make the floor structure layer meet the requirements and design of the next process construction In accordance with the requirements of the regulations, measures must be taken to make a leveling layer, which not only wastes a lot of labor and energy, but also prol...

Problems solved by technology

[0003] In view of the above situation, in order to overcome the defects of the prior art, the object of the present invention is to provide a floor thickness control block, which can effectively solve the difficulty in controlling the height and flatness of the floor during construction, and the follow-up treatment of the leveling layer is required, resulting in labor-intensive and cost-intensive The problems of energy and long construction period
