Embodiment Construction

[0031] combine Figure 1~5 As shown, the present invention carries out the masonry 1 performance detection method of autoclaved aerated concrete block, and the steps include:

[0032] 1) Masonry 1. After the maintenance is completed, put the masonry 1 down and transfer it to the loading platform of the testing equipment; lay the masonry 1 flat, use 3 round steel pipe pads at one end, and 4 angle steel pads at the other end Pad, the corners of the angle steel 4 are in contact with the lower surface of the masonry 1;

[0033] 2), then use jack 7 to apply load to the surface of masonry 1 from top to bottom; loading speed: 0.03-0.3N / mm per minute 2 , the loading speed is controlled according to the failure of the specimen within 3min to 5min;

[0034] 3) Record the failure load value and failure characteristics, calculate and process the test data to obtain the test results.

[0035] In terms of steps, the steps 1) are as follows: Figure 4 , 5 As shown, the masonry 1 is plac...

Abstract

The invention relates to detection on the mechanical performance of building members, and particularly provides an autoclaved aerated concrete block masonry performance detection method. The method comprises the following steps: 1) laying a masonry and maintaining, then laying down the masonry, and transferring to a loaded platform of detection equipment; putting the masonry flat, supporting one end with a round steel tube, and supporting the other end with angular steel, wherein the corners of the angular steel are contacted with the lower surface of the masonry; 2) then applying load to the surface of the masonry with a jack from top to bottom at the application speed of 0.03-0.3N / mm<2> per minute, wherein the application speed is controlled according to collapse of a test piece in 3min-5min; and 3) recording the collapse load value and the collapse feature, and calculating and processing test data to obtain a test result. The autoclaved aerated concrete block masonry performance detection method is suitable for performance detection of blocks or masonry. The method has the effects of being convenient to detect and implement, and beneficial to improvement of detection standardization and detection precision.

Description

technical field [0001] The invention relates to a testing method and testing equipment for mechanical properties of building components. Background technique [0002] Autoclaved aerated concrete blocks are mainly used for external filling walls and non-load-bearing internal partition walls of buildings, and can also be combined with other materials to form composite walls with thermal insulation functions. The unit volume weight of the autoclaved aerated concrete block is one-third of that of clay bricks, its thermal insulation performance is 3-4 times that of clay bricks, its sound insulation performance is twice that of clay bricks, and its impermeability is more than double that of clay bricks. , the fire resistance is 6-8 times that of reinforced concrete. The masonry strength of the block is about 80% of the strength of the block itself (30% for the red brick). [0003] With the continuous advancement of my country's wall material innovation, energy conservation and e...
