Bidirectional self-balance shear loading device for fired shale masonry and test method therefor

Abstract

The invention discloses a bidirectional self-balance shear loading device for a fired shale masonry and a test method therefor. The loading device comprises a base, wherein two vertical bolt rods are symmetrically mounted at the two ends in the width direction of the base; vertical loading steel beams are mounted at the upper ends of the two vertical bolt rods; the vertical loading steel beams comprise two first parallel horizontal plates and two first vertical plates connected in parallel between the first horizontal plates; mounting holes are symmetrically formed in the two ends of each first horizontal plate; the upper ends of the vertical bolt rods penetrate through the mounting holes of the two first horizontal plates of the vertical loading steel beams and are fixedly connected; and the top ends of the vertical bolt rods are fixed to the first horizontal plates on the upper side through vertical screw caps and gaskets. The bidirectional self-balance shear loading device adopts a matched instrument, is quick to assemble or disassemble and movable, can make full use of a test site, and is simple and convenient for loading a test piece and higher in bidirectional self-balance loading stability.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a loading device and method for a block strength test, in particular to a two-way self-balancing shear-compression loading device for sintered shale masonry and a testing method thereof. Background technique [0002] At present, my country's existing construction area has reached 42 billion m 2 , and still maintain about 2 billion m 2 / year huge growth rate. The total energy consumption of buildings is about 870 million tons of standard coal per year, accounting for nearly one-third of the total energy consumption of the society. About 80% of the heat consumption of buildings is mainly transmitted in or out through the heat transfer of the building envelope. Compared with developed countries, the utilization rate of energy-saving sintered wall materials in my country is still very low, and wall materials in foreign developed countries are developing in the direction of h...

Problems solved by technology

[0004] The traditional masonry shear compression loading device usually includes a reaction frame, a jack and a sensor. Since the reaction frame is fixed on the ground, the device cannot be moved, which greatly limits the test conditions and greatly reduces the convenience of the test; at the same time, The lateral rigidity of the support of the reaction force frame is insufficient, resulting in a decrease in the stability of the reaction force frame when the axial pressure is large, which often leads to the failure of the test
