Single brick in situ double shear device is a special testing instrument for testing the shear strength of building masonry. Be sure to read the instructions carefully before use. It is operated by ** experimental personnel to avoid injury caused by improper operation. For more information, please contact our customer service staff.

單磚原位雙剪儀是一臺(tái)小型液壓裝置，通過活塞上升推動(dòng)蓋板對(duì)砌塊產(chǎn)生作用力檢測(cè)砌體抗剪強(qiáng)度，使砌塊上下兩個(gè)面發(fā)生剪切，通過測(cè)定砌塊發(fā)生剪切時(shí)的力來計(jì)算砌體的抗剪強(qiáng)度，測(cè)試結(jié)果直觀性強(qiáng)，檢測(cè)部位局部破損。由上海榮計(jì)達(dá)儀器科技有限公司提供，設(shè)備質(zhì)保期一年，一年內(nèi)產(chǎn)品如有質(zhì)量問題，供方負(fù)責(zé)免費(fèi)維修。如果因操作不當(dāng)或者人為損壞，我公司亦應(yīng)提供維修、更換服務(wù)，由此產(chǎn)生的費(fèi)用我公司會(huì)酌情收取。

The single brick in-situ double shear device is a small hydraulic device that detects the shear strength of the masonry by pushing the cover plate to push the cover to exert force on the masonry. The cutting force is used to calculate the shear strength of the masonry. The test results are intuitive and the detection site is partially damaged. Provided by Shanghai Rongjida Instrument Technology Co., Ltd., the equipment warranty period is one year. If the product has quality problems within one year, the supplier is responsible for free maintenance. If due to improper operation or man-made damage, our company should also provide repair and replacement services, and the costs incurred by our company will be charged as appropriate.

單磚原位雙剪儀特點(diǎn)：

1.該儀器結(jié)構(gòu)新穎，體積小巧，質(zhì)量輕盈，操作方便。

2.采用手動(dòng)泵加荷油缸，操作簡(jiǎn)單方便，互換性強(qiáng)。

3.數(shù)字顯示壓力表，可直接讀出剪切力。

Features of single brick in situ double shear

1. The instrument has a novel structure, small size, light weight and easy operation.

2. The manual pump is used to load the oil cylinder, the operation is simple and convenient, and the interchangeability is strong.

3. Digital display pressure gauge can directly read the shearing force.

單磚原位雙剪儀操作方法：

■所示，**先將砌塊相鄰一端的另一砌塊掏出，清除四周的灰縫，制備出安放主機(jī)的孔洞。其截面尺寸不得小于115mmX65mm，然后掏空并清除砌塊另一端的豎縫。

■砌塊兩端的灰縫應(yīng)清理干凈。開鑿清理過程中，嚴(yán)謹(jǐn)擾動(dòng)砌塊;如發(fā)現(xiàn)砌塊有明顯缺棱掉角或上下灰縫有明顯松動(dòng)現(xiàn)象時(shí)，應(yīng)舍棄該砌塊。被推砌塊的承壓面應(yīng)平整，否則應(yīng)用變砂輪等工具磨平。

■將雙剪儀主機(jī)放入開鑿好的孔洞中，使儀器的蓋板與砌塊的頂面重合，儀器軸線與砌塊軸線吻合，若開鑿孔洞過長(zhǎng)，應(yīng)在儀器尾部另加墊塊。

■壓動(dòng)手動(dòng)泵，使雙剪儀對(duì)砌塊均勻施加水平載荷，直至砌塊和砌體之間相對(duì)位移，砌塊達(dá)到破壞狀態(tài)。加荷的全過程宜為1-3min。

■記錄砌塊破壞時(shí)數(shù)字壓力表的讀數(shù)。根據(jù)此讀數(shù)可計(jì)算出灰縫面的抗剪強(qiáng)度。

Single brick in situ double shear instrument operation method

■ As shown, ** first pull out the other block adjacent to the block, remove the gray seams around it, and prepare a hole for the host. Its cross-sectional dimension should not be less than 115mmX65mm, and then hollow out and remove the vertical seam at the other end of the block.

■ The gray joints at both ends of the block should be cleaned up. During the excavation and cleaning process, the block is disturbed rigorously; if it is found that the block has obvious edges and corners or the upper and lower gray joints have obvious loosening, the block should be discarded. The pressure-bearing surface of the pushed block should be flat, otherwise it should be smoothed by tools such as variable grinding wheels.

■ Put the main body of the double-scissor instrument into the excavated hole, so that the cover plate of the instrument coincides with the top surface of the block, and the axis of the instrument coincides with the axis of the block. If the excavated hole is too long, another block should be added at the end of the instrument.

■ Press the manual pump to make the double shear device apply the horizontal load evenly to the block until the block and the block are displaced relative to each other, and the block reaches the damaged state. The whole process of loading should be 1-3min.

■ Record the digital pressure gauge reading when the block is broken. Based on this reading, the shear strength of the gray seam surface can be calculated.
