一、40×40×160水泥抗折夹具用于水泥胶砂抗折试验。符合JC/T683-1997、GB/T17671-1999标准要求。是水泥实验室是试验夹具适用于任何类型的压力试验机,使用时应将本夹具安放在压力试验机下压力板上,由夹具底部Ф8孔定位以对A位置,然后把上、下压力板平面上擦干净,放入水泥试块,试块宽的一边紧靠定位销调整压力试验机的上压力板与夹具的上球座的上平面接触,便可以加压,记录试块压碎时压力试验机的示值 单位:N,除以试块面积(40×40=1600mm2)即可很方便地求出抗压强度 单位:MPa。

First, the 40 × 40 × 160 cement flexural clamp is used for the flexural test of cement mortar. Meet the requirements of JC / T683-1997 and GB / T17671-1999. It is a cement laboratory. The test fixture is suitable for any type of pressure testing machine. When using this fixture, it should be placed on the lower pressure plate of the pressure test machine. It is positioned by the Ф8 hole at the bottom of the fixture to position A. Wipe clean on the surface and put in the cement test block. The wide side of the test block is close to the positioning pin to adjust the upper pressure plate of the pressure testing machine and the upper surface of the upper ball seat of the clamp. The display unit of the pressure testing machine: N, divided by the area of the test block (40 × 40 = 1600mm2), can easily find the compressive strength unit: MPa.


二、40×40×160水泥抗折夹具技术参数:

规格:40×40×160

上、下压力板长度40±0.1mm。

压辊直径 10mm

下压辊跨距100mm。

净重≈6kg。

Technical parameters of 40 × 40 × 160 cement anti-bending fixture:

Specifications: 40 × 40 × 160

The length of the upper and lower pressure plates is 40 ± 0.1mm.

Pressure roller diameter 10mm

The pressing roller span is 100mm.

Net weight ≈ 6kg.


三、性能特点:

1.具有坚固的夹具体,在夹具体下部孔内固定着下压力板,用作承放水泥试块之用。

2.在下压力板上装有二只定位销,用于试块定位。

3.夹具体上部孔内紧配衬套,衬套内装有上球座,上球座在孔内能自由轴向移动和转动。上压力板由挂簧销,拉簧,螺母,球面圆柱头螺钉,相互连接,挂吊在夹具体上,并与上球座球面接触,以保证试块上、下平面不平行时,使上压力板能自动回转,使其平面与试块上平面紧密接触,在上压力板一侧装有导向圆销,插入夹具体中部长槽内,使上压力板不能在水平面转动。

4.通过旋转球面圆柱头螺钉可调整上压力板的高低位置。上、下压力板之距一般调整为45~50,当试块加压时,上球座受力向下移动,使上压力板接近试块上平面,卸压后由于拉簧作用,上压力板能自动复位

Performance characteristics of 40 × 40 × 160 cement anti-bending fixture:

1. It has a solid clamp concrete, and a lower pressure plate is fixed in the lower hole of the clamp concrete, which is used for holding the cement test block.

2. Two positioning pins are installed on the lower pressure plate for positioning the test block.

3. The upper hole of the clip is tightly matched with a bushing. The bushing is provided with an upper ball seat, and the upper ball seat can freely move and rotate axially in the hole. The upper pressure plate is connected to each other by a hanging spring pin, a tension spring, a nut, and a spherical cylinder head screw. It is hung on the clamp and contacts the spherical surface of the upper ball seat to ensure that the upper and lower planes of the test block are not parallel. The pressure plate can rotate automatically so that its plane is in close contact with the upper surface of the test block. A guide round pin is installed on one side of the upper pressure plate and inserted into the middle slot of the clamp to prevent the upper pressure plate from rotating on the horizontal plane.

4. The height of the upper pressure plate can be adjusted by rotating the spherical cylinder head screw. The distance between the upper and lower pressure plates is generally adjusted to 45 ~ 50. When the test block is pressurized, the upper ball seat is forced to move downward to bring the upper pressure plate close to the upper plane of the test block. Board can reset automatically


四、注意事项:

使用完毕后及时清除试块碎屑,各运动部位涂抹润滑油,各光面涂抹防锈油以防腐蚀。

Four, 40 × 40 × 160 cement anti-bending fixture matters needing attention:

After use, remove the test piece debris in time, apply lubricating oil to each moving part, and apply anti-rust oil to each smooth surface to prevent corrosion.


五、结构组成:

水泥抗折夹具主要由下夹具座、上夹具座、标准夹辊、抗劈裂夹具上下压条等组成。下夹具座通过定位销(、垫圈固定在压力机活塞上,上夹具座通过上支座、菱形销及压力机上的定位销和两内六角螺钉固定在压力机横梁上。

Five, 40 × 40 × 160 cement anti-bending fixture structure composition:

The cement anti-bending fixture is mainly composed of a lower fixture base, an upper fixture base, a standard nip roller, and an upper and lower bead of a crack-resistant fixture. The lower clamp seat is fixed on the press piston by positioning pins (and washers), and the upper clamp seat is fixed on the press beam by the upper support, diamond pins, and positioning pins on the press and two hexagonal screws.
