Abstract

The invention relates to a slide-type concrete surface smoothness test device, belonging to the field of the test of a concrete material, and solving the problem that no device which can be conveniently, accurately and rapidly used for quantitatively evaluating the surface smoothness of the concrete exists both at home and abroad at the present. The upper end of a box body is provided with a plurality of rod holes, wherein the inner wall of each rod hole is provided with a through hole running through the side surfaces of the box body, the upper end of each straight rod is provided with a suspension ring, the side wall of each straight rod is provided with a pin shaft hole, the straight rods are respectively arranged in the rod holes, a positioning pin is sequentially arranged inside the through hole and the pin shaft hole on the straight rod in a penetrating way, the left side of the box body is provided with a pulley, the right side of the upper end of the box body is provided with a rope pole, one end of a rigid rope is fixed on the rope pole, the other end of the rigid rope is fixedly provided with a balancing weight, the weight of the balancing weight is smaller than half of the weight of each straight rod, the rigid rope is sequentially arranged in the suspension rings in a penetrating way, and a fixed point at the right end of the rigid rope, the central line of the rod holes and the center of the pulley are on a same vertical plane. The slide-type concrete surface smoothness test device is used for evaluating the surface smoothness of the concrete.

Description

technical field [0001] The invention relates to a concrete surface testing device, which belongs to the field of concrete material testing. Background technique [0002] As a new type of rapid mechanical construction method for modern concrete engineering structures, slipform construction is widely used in many construction engineering fields such as highways and airport pavements. Since the dry hard concrete used in the traditional sliding form construction technology can only be fully compacted under intensive external vibration conditions, the actual project is often destroyed prematurely due to the over-vibration of the concrete in the local area around the vibrator. In response to this specific technical problem, in recent years, it has been proposed at home and abroad to apply modified self-compacting concrete to slipform construction without vibrating forming. Since high fluidity is required to achieve the effect of vibration-free self-compacting, and high cohesion i...
