Embodiment Construction

[0021] The following are specific embodiments of the present invention and the technical solution of the present invention is further described in conjunction with the accompanying drawings, but the present invention is not limited to the following embodiments.

[0022] Such as figure 1 As shown, the concrete slump integrated test device includes a bottom plate 1, and a scale plate 2 and a fixed plate 3 are vertically fixed on the bottom plate 1. The bottom plate 1, the scale plate 2 and the fixed plate 3 are perpendicular to each other. The area enclosed by the scale plate 2 and the fixed plate 3 has a flat test area 1a; a laser emitter 4 capable of emitting a word line is fixed on the base plate 1 facing the scale plate 2, and the test area 1a of the base plate 1 is placed. The slump cylinder 5 and the slump cylinder 5 are located between the scale plate 2 and the laser emitter 4; the slump cylinder 5 has a double-layer structure and a heating wire 6 is arranged between the ...

Abstract

The invention provides a concrete slump integrated test device, which belongs to the technical field of test devices, and solves the technical problems that an existing concrete slump test device is not convenient and accurate enough to use and the like. The test device comprises a bottom plate, a scale plate and a fixing plate are vertically and fixedly arranged on the bottom plate, the bottom plate, the scale plate and the fixing plate are perpendicular to one another in pairs, and a flat test area is arranged in the area, defined by the scale plate and the fixing plate, of the bottom plate;a laser emitter capable of emitting a straight line is fixedly arranged at the position, right opposite to the scale plate, of the bottom plate, and a slump cone is placed in a test area of the bottom plate and located between the scale plate and the laser emitter; the slump cone is of a double-layer structure, and a heating wire is arranged between double layers; scale values are arranged on theside surface, facing the test area, of the scale plate; a connecting rod capable of lifting and horizontally moving is arranged on the fixing plate; one end of the connecting rod can be inserted intothe slump cone. The concrete slump integrated test device is accurate and reliable in test data and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of testing devices, and relates to an integrated testing device for concrete slump. Background technique [0002] Concrete slump mainly refers to the plasticizing performance and pumpability of concrete, including the water retention, fluidity and cohesion of concrete. Factors affecting concrete slump mainly include gradation changes, water content, weighing deviation of weighing instruments, dosage of admixtures, etc., and the temperature of cement is easily overlooked. The so-called slump test is a work that must be done to test the performance of concrete when pouring concrete in construction. Only by measuring the concrete that meets the slump requirements can the normal progress of construction and the quality of concrete buildings be guaranteed. At present, when measuring the slump of concrete, the horn-shaped slump cylinder is usually placed on the ground, and then the concrete is poured into it and ...
