specific Embodiment approach 1

[0007] Specific Embodiment 1: This embodiment is described in conjunction with FIGS. 1 to 5. The fiber concrete mixing uniformity measuring instrument of this embodiment includes a housing 1, a sampling rod 2 and a sliding pin 5. The front part of the housing 1 is conical. The rear part of the housing 1 is sleeve-shaped, and the rear part of the housing 1 is divided into six areas clockwise along the cross section of the housing 1 from back to front, which are the first non-porous area 1-1, the first Slotted area 1-2, first pore area 1-3, second non-porous area 1-4, second slit area 1-5 and second pore area 1-6, the first slit area 1-2 and the long grooves 11 of the second slotted area 1-5 are opened along the length direction of the shell 1, and the plurality of holes 12 of the first holed area 1-3 and the second holed area 1-6 are along the length of the shell 1. 1 in the length direction, the length of the first slotted area 1-2, the second slotted area 1-5, the first holed...

specific Embodiment approach 2

[0008] Specific embodiment two: This embodiment is described in conjunction with Figs. 1 and 2, a shoulder 4 is formed between two adjacent grooves 3 of each row of grooves in this embodiment, and a shoulder 4 is formed along the length direction of the sampling rod 2 on the shoulder 4 Dimple 13 is arranged. With such arrangement, the sampling rod has a stronger drawing force, and can draw fibers distributed horizontally and vertically. Other compositions and connections are the same as in the first embodiment.

specific Embodiment approach 3

[0009] Specific Embodiment Three: This embodiment is described with reference to FIGS. 1 and 2 . The measuring instrument of this embodiment is further provided with a hand wheel 6 , and the hand wheel 6 is fixed on the rear end of the sampling rod 2 . With such setting, the operation is more convenient. Other compositions and connections are the same as those in Embodiment 1 or Embodiment 2.

[0010] Working principle (see Figures 1 to 5), the sampling rod 2 is inserted into the casing 1, the sliding pin 5 enters the axial groove 9, the handwheel 6 is turned, the sliding pin 5 slides into one end of the circumferential groove 10, and the sampling rod The groove 3 and the dimple 13 on the 2 are covered by the first non-porous area 1-1 and the second non-porous area 1-4 of the shell 1, and the measuring instrument is vertically inserted into the fiber concrete to be measured, clockwise Turn the hand wheel 6, the sliding pin 5 slides to the other end of the circumferential groo...

Abstract

The invention relates to a fibre concrete agitation evenness measuring apparatus, solving the problem that the distribution evenness of fibre in fibre concrete cannot be measured. One end of a sampling rod (2) in the invention is arranged in a shell (1), the sampling rod (2) is symmetrically equipped with two rows of grooves along the radial direction of the sampling rod (2), multiple grooves areequidistantly arranged along the length direction of the sampling rod (2), and the length of each row of the grooves is the same as that of a first grooving region (1-2); the wall at the tail end of the shell (1) is equipped with an axial groove (9) and a circumferential groove (10) communicated with the axial groove (9), the axial groove (9) and the circumferential groove (10) form a sliding guide groove of a sliding pin (5), one end of the sliding pin (5) is fixed on the sampling rod (2) and the other end of the sliding pin (5) slides in the sliding guide groove. The invention realizes the measurement of distribution evenness of fibre in fibre concrete. The invention has the characteristics of accurate measurement, small error and simple structure.

Description

technical field [0001] The invention relates to a concrete mixing uniformity measuring instrument. Background technique [0002] Fiber-reinforced concrete, also known as fiber-reinforced concrete, is a cement-based composite material composed of cement paste, mortar or concrete as the base material and fiber as the reinforcing material. 3 Due to the dispersion of various fibers in different numbers in fiber concrete, its reinforcing effect spreads throughout all parts of the concrete, making it appear as a homogeneous material as a whole. At present, the fiber concrete with mature technology includes steel fiber concrete, glass fiber concrete and polypropylene fiber concrete and so on. For example, fiber concrete, especially steel fiber concrete, has been successfully applied in large-area concrete projects in my country. Such as the covering and structure of the bridge deck part, the road surface, the airstrip, the pavement and structure of the tank parking lot, mining an...
