Abstract
The present invention is the buildings brick strength method of inspection and device fabrication thereof, and core is to measure shearing strength with brick wall list brick shearing test device.This device comprises that the join opposite side of pulling force sensor of activity that anchor clamps are fixed by bolts to a side draw sensor of anchor clamps on the one brick wall body opens in the slideway with loading rotating disk fixed and arranged reaction frame one side with traveling nut, and the loading rotating disk drives pulling force sensor and writes down numerical value by electronic scales.The device that this method is designed, rational in infrastructure, the starting material simple to operation wide cost of originating is lower.
Description
The present invention relates to a kind of strength test of building brick method and apparatus, further talking is the existing intensity that a cover test verification has been built mortar in the engineering brick setting, is applicable to the check of new and old building thing body of wall mechanical performance indexs such as public building, residential houses, industrial premises.
Determine the brick setting compressive strength of existing building, bending and tensile strength, mechanical performance index keys such as shearing strength are how scientifically to measure exactly the mortar strength in the brick setting, measure the label of brick again, then the above-mentioned mechanical performance index of brick setting just can be tried to achieve the conventional rebound method test mortar strength that adopts according to relevant calculation formula in the standard more and promptly be inferred its intensity with the skin hardness of mortar in the reisilometer test masonry mortar joint, this method and apparatus, not accurate enough, science, because it can not reflect the influence of construction masonry quality to the masonry project mechanical property truly, on the low side as full degree of mortar at bed joint, wall on the hacking, mortar is long service time, the incorrect grade of building method all will directly influence the mechanical property of masonry, so part provinces and cities have stopped using rebound method test mortar strength.
In recent years, many accidents resulting from poor quality of projects had appearred in construction work.Use inferior materials and turn out substandard goods, barbarous construction causes poor workmanship, therefore the dispute case that takes place is of common occurrence.Connect layer enlarging on old buildings, because the masonry mechanical index is unclear, the original calculation index is often for supposition, or because of means of testing falls behind the measured result distortion, makes the design error, caused accident resulting from poor quality of projects.So the brick setting quality is pressed for the detection testing equipment and the method for science.
The objective of the invention is to avoid above-mentioned weak point of the prior art to invent a kind of equipment accurate, that science is simple in structure by force, practicality is higher of measuring, propose a kind of simple method of testing and computing method.
Purpose of the present invention can realize by following measure:
Described single brick shearing test device includes the pull sensing apparatus, is connected with electronic scale on it.Steel disc in the anchor clamps is by being bolted on the body of wall list brick, one side of anchor clamps and pulling force sensor flexibly connect, the opposite side of pulling force sensor is fixed and is arranged in reaction frame one side of the geometric configuration of the same surface level of anchor clamps and opens in the slideway with the loading rotating disk with traveling nut, rotate the loading rotating disk and drive pulling force sensor, at this moment the electronic scale video data.
Purpose of the present invention can realize by following scheme:
The relation of determining mortar strength and masonry strength in the masonry structure directly on body of wall single brick shear test find out mortar, determine mortar strength, utilize relevant formula to calculate the intensity index of brick setting, R=f(R1R2), Rj=f(R2), Rl=f(R2), Rw=f(R2).And concern R-masonry strength, Rw-bending and tensile strength, Rl-axial tensile strength, Rj-shearing strength between the shear resistance of the horizontal adhesive surface of single brick and the mortar strength full degree of mortar at bed joint.
Describe in detail below in conjunction with accompanying drawing embodiment:
Fig. 1 is an equipment synoptic diagram of the present invention.
1 anchor clamps, 2 reaction frames, 3 loading rotating disks, 4 poles (flexible), 5 pulling force sensors, 6 electronic scales etc. are partly formed (seeing accompanying drawing for details).During operation: adjust pole 4 after anchor clamps 1 are clamped single fragment of brick, make reaction frame 2 and anchor clamps 1 be in same horizontality, adjusting electronic scale 6 simultaneously, to make initial reading be zero.Manually at the uniform velocity rotate loading rotating disk 3, pulling force sensor 5 was in the tension duty and reached electronic scale 6 by the lead electric signal and shows load numerical value this moment.The value of reading and the full degree of mortar at bed joint of electronic scale 6 when noting fragment of brick and cutting up.Carry out a certain amount of test back by relevant calculation formula in the strength test of building brick, can calculate the existing intensity of mortar, by the mechanical performance index that can calculate body of wall in the masonry standard about formula, for the relevant works skill
Described single brick shearing test device includes the pull sensing apparatus, is connected with electronic scale on it.Steel disc in the anchor clamps is by being bolted on the one brick wall body, reaction frame one side that the same surface level of anchor clamps was fixed and be arranged in to the opposite side of one side of anchor clamps and pulling force sensor flexible connection pulling force sensor with traveling nut with the loading rotating disk is opened in the slideway, rotates the loading rotating disk and drives pulling force sensor electronic scale video data this moment.
The relation of determining mortar strength and masonry strength in the masonry structure directly on body of wall single brick shear test find out mortar, determine mortar strength, utilize relevant formula to calculate the intensity index of brick setting, R=f(R1R2), Rj=f(R2), Rl=f(R2), Rw=f(R2).And concern R-masonry strength, the existing intensity of R2-, Rl-axial tensile strength, Rj-shearing strength between the shear resistance of the horizontal adhesive surface of single brick and the mortar strength full degree of mortar at bed joint.
Brick wall list brick shearing test device partly is the off-the-shelf except that pulling force sensor, electronic scale, and remaining part all adopts common iron to make the light practicality of equipment.
Good effect of the present invention: this method of testing can reflect the influence of construction factor to the masonry project quality truly, as previously mentioned factors such as full degree of mortar at bed joint.More science is truer for the mechanical property of masonry index of measuring.
The device that this method is designed, rational in infrastructure, the starting material simple to operation wide cost of originating is lower.
