specific Embodiment approach 1

[0016] Embodiment 1: Combining Figure 1 to Figure 3 Illustrating this embodiment, the multifunctional concrete single-pull test piece forming and experimental device in this embodiment includes a mold base plate 1 , two mold side plates 2 , a mold upper cover 11 and two mold fixture units, and two mold side plates 2 The two ends of each mold side plate 2 are respectively connected to two of the mold clamp units, and the mold upper cover 11 is connected to the mold side plate 2 and the mold clamp units. The mold side plate 2 is made of steel plate, and can be stacked in the thickness direction. The mold base plate 1 has a certain strength and rigidity, which is sufficient to ensure that the bottom surface of the concrete bottom surface is flat after prefabrication and does not deform. The mold upper cover 11 has certain strength and rigidity, and can be made of transparent materials, such as plexiglass, etc., which is convenient for observing the molding quality of the test p...

specific Embodiment approach 2

[0017] Specific implementation mode 2: Combining Figure 1 to Figure 3 Illustrating this embodiment, each of the end plate fixture units of the multifunctional concrete single tensile test piece forming and experimental device in this embodiment includes a fixture 3, a tie rod 4 and two connecting plates 5, and the two connecting plates 5 are arranged in parallel , one end of the pull rod 4 is connected with one end of the two connecting plates 5 , and the clamp 3 is connected with the other ends of the two connecting plates 5 .

[0018] The fixture 3 can be assembled from different thicknesses of steel with extremely high tensile strength according to the thickness of the tensile specimen. The fixture should be symmetrically designed to ensure that the axis is consistent with the axis of the specimen. The contact surface between the fixture and the concrete should be set in an arc shape.

[0019] The strength of the tie rod 4 is large enough to ensure that neither damage no...

Abstract

The invention discloses a multifunctional concrete single-pull test part molding and experiment device, relates to a multifunctional test part molding and experiment device, in particular to a multifunctional concrete single-pull test part molding and experiment device, and aims to solve the problem that eccentricity is caused as a conventional concrete single-shaft pull test part is relatively incomplete in contact. The device comprises a bottom plate, two side mold plates, an upper mold cover and two mold clamping units, wherein the two side mold plates are arranged on a bottom mold plate; two ends of each side mold plate are respectively connected with the two mold clamping units; and the upper mold cover and the side mold plates are connected with the mold clamping unit. The device belongs to the field of buildings.

Description

technical field [0001] The invention relates to a multifunctional test piece forming and experimental device, in particular to a multifunctional concrete single tensile test piece forming and experimental device, which belongs to the field of construction. Background technique [0002] In the uniaxial tensile test of concrete, it is difficult to obtain the ideal uniaxial tensile performance because it is easy to produce eccentricity, which leads to the eccentric tensile failure of concrete, and although there are standards that specify the uniaxial tensile performance requirements of concrete. However, the current uniaxial tensile test fixtures have not been unified, and some fixtures cannot be automatically aligned in the experiment, resulting in the failure of the experiment due to eccentricity, and it is difficult to ensure the experimental effect. Moreover, only three sides of the uniaxial tensile test specimen are molds The molding surface and the top surface are manual...
