Then, after fixing the curtain wall beam 33, rotate the rotating handle 12 to rotate the rotating rod 13 and push the connecting plate 14 to slide in the first sliding groove 15. At the same time, since the curtain wall beam 33 is fixed in the clamping block 30, the two connecting plates 14 are moved in opposite directions to test the tensile strength of the curtain wall beam 33.

[0022] In the above scheme, the sliding of the connecting plate 14 is achieved by the first sliding groove 15 on the two testing frames 1, the sliding and limiting of the connecting plate 14 in the first sliding groove 15 is achieved by the rotating rod 13 on the connecting plate 14, the curtain wall beam 33 is fixed by the two uprights 16 on the connecting plate 14 and the clamping blocks 30 on the two uprights 16, the rotation of the rotating rod 13 is achieved by the rotating handle 12 on the rotating rod 13, and the movement of the testing frame 1 is achieved by the handle 11 on the testing frame 1.

[0023] As a further embodiment of this utility model, according to Figure 1 and Figure 2 As shown, four third screws 31 are provided on the curtain wall beam 33 in a rectangular array.

[0024] Furthermore, including a third screw 31, a fixing box 27 is movably disposed on the clamping block 30, the third screw 31 passes through the fixing box 27 and clamps the block 30 and is fixed on the fixing box 27, and the fixing box 27 has symmetrically opened insertion holes 28 on both sides, and a second screw 29 is provided in the internal thread of the insertion hole 28.

[0025] Furthermore, both the clamping block 30 and the fixing box 27 are provided with a third sliding groove 32, in which the curtain wall beam 33 slides.

[0026] Furthermore, an anti-slip component 34 is provided inside the third sliding groove 32, and the curtain wall beam 33 is located inside the anti-slip component 34.

[0027] Specifically, after fixing the curtain wall beam 33 into the anti-slip member 34 in the third sliding groove 32, the third screw 31 is rotated and passes through the clamping block 30 into the fixing box 27, fixing the clamping block 30 and the fixing box 27 together. Then, the second screw 29 located in the insertion hole 28 is rotated. The second screw 29 will push against the anti-slip member 34 in the third sliding groove 32, and the anti-slip member 34 will further fix the curtain wall beam 33, preventing the curtain wall beam 33 from sliding during the tensile test.

[0028] As a further embodiment of this utility model, according to Figure 2 As shown, each of the two uprights 16 is slidably provided with a collar 17, and an ear plate 18 is fixedly provided on the collar 17. The ear plate 18 is provided with a fixing hole 19.

[0029] Furthermore, a fixing block 20 is provided between the two collars 17, and sliding shells 24 are symmetrically provided on both sides of the fixing block 20.

[0030] Furthermore, sliding blocks 23 are symmetrically arranged on both sides of the fixed block 20, and a second sliding groove 25 is provided on the sliding shell 24, and the sliding block 23 slides in the second sliding groove 25.

[0031] Furthermore, a limit box 21 is provided at the bottom of the fixed block 20, and a first screw 22 is rotatably provided inside the limit box 21, with a push plate 26 provided on the first screw 22.

[0032] Specifically, the collar 17 is fitted onto the upright 16, and then the threaded screw is inserted into the fixing hole 19 and tightened to fix the collar 17 onto the upright 16. When the test frame 1 is moved, the sliding blocks 23 on both sides of the fixing block 20 will slide in the second sliding groove 25 opened in the sliding shell 24. After the tensile test is completed, the first screw 22 is rotated and rotated upward in the limit box 21, pushing the push plate 26 upward, and the curtain wall beam 33 is pushed to test the bending resistance of the curtain wall beam 33.

[0033] Working principle: In use, first, put the collar 17 onto the upright 16, then insert the threaded screw into the fixing hole 19 and tighten it to fix the collar 17 onto the upright 16. Pull the handle 11 to move the detection frame 1. After the detection frame 1 moves to the designated position, install the curtain wall beam 33 in the two clamping blocks 30. After fixing the curtain wall beam 33 in the anti-slip part 34 in the third sliding groove 32, rotate the third screw 31 and pass it through the clamping block 30 into the fixing box 27 to fix the clamping block 30 and the fixing box 27 together.

At the same time, since the curtain wall beam 33 is fixed in the clamping block 30, the two connecting plates 14 are moved in opposite directions to test the tensile strength of the curtain wall beam 33. Then, when the test frame 1 is moved, the sliding blocks 23 on both sides of the fixed block 20 will slide in the second sliding groove 25 opened in the sliding shell 24. After the tensile test is completed, rotate the first screw 22 to rotate upward in the limit box 21 and push the push plate 26 upward, pushing the curtain wall beam 33 to test the bending resistance of the curtain wall beam 33.

[0034] All fixed connections mentioned above are welded, while rotating connections are set as rotating bearing connections.
