A non-movement clamp for tensile testing of ultra-high strength steel bars includes an upper clamping block structure and a lower clamping block structure with similar structures. The upper clamping block structure includes an upper clamping block, an upper clamping shaft, an upper shaft cap, and an upper combined ring. The upper clamping block includes two semi-circular clamping blocks, and a combined ring step is provided on the outer side of the lower end of the semi-circular clamping blocks. The upper combined ring is fitted onto the outer side of the upper clamping block and contacts the combined ring step. The interior of the semi-circular clamping block has a sample mounting area and an upper clamping shaft mounting area that are connected vertically. One end of the sample is clamped in the sample mounting area. The lower end of the upper clamping shaft and the upper shaft cap are threaded together and clamped in the upper clamping shaft mounting area. The upper shaft cap contacts the end of the sample. The other end of the upper clamping shaft is connected to the wedge clamping end of the tensile testing machine. This utility model uses a combined ring to fix the clamping blocks together. The clamping block body has no structural damage. The sample limiting device composed of the upper and lower clamping shafts and the upper and lower shaft caps can limit the position according to the position of the sample, and has high applicability.

The suspended ceiling structure comprises two main keels, auxiliary keels are arranged on the two sides of the tops of the main keels respectively, adjusting components are arranged on the auxiliary keels, and fixing components are arranged between the auxiliary keels and the main keels. The adjusting component comprises movable frames arranged on the two sides of the auxiliary keel in a sleeving mode, first supporting rods fixedly connected with the tops of the movable frames, adjusting grooves formed in the tops of the first supporting rods, second supporting rods arranged in the adjusting grooves and protrusions fixedly connected with one sides of the first supporting rods. By arranging the two main keels, the auxiliary keels, the adjusting parts and the fixing parts, the problems that although the positions of the auxiliary keels can be adjusted when an existing suspended ceiling structure is used, the height of the whole suspended ceiling is fixed, the height of the suspended ceiling is inconvenient to adjust according to actual requirements, and the auxiliary keels are fixed through threaded pins, so that the service life of the suspended ceiling is prolonged are solved. And the efficiency is low during adjustment, so that the practicability becomes poor.

The invention relates to the field of constructional engineering equipment, and discloses a constructional engineering early-dismantling supporting device which comprises a stand column, a lifting mechanism is arranged at the upper end of the stand column, and a support and a top block are installed at the upper end of the stand column through the lifting mechanism. By rotating the threaded sleeve, stabilizing the position of the threaded sleeve through the positioning assembly and stabilizing the position of the stud through the first limiting assembly, the stud can be driven by the stud to move longitudinally, so that the supporting height of the support is adjusted through the lifting mechanism, and the support can adapt to the supporting positions of early-dismantling formworks with different heights; the distance between the top block and the support can be conveniently adjusted through the adjusting assembly so as to adapt to early-dismantling formworks of different thicknesses, the sliding rod is pulled to slide in the sliding groove, the position of the sliding rod is stabilized through the second limiting assembly, and then the distance between the supporting block and the supporting rod can be adjusted through the extending assembly so as to adapt to early-dismantling formworks of different thicknesses. Therefore, the supporting area of the top block can be increased through the supporting block, and the supporting position of the early-dismantling supporting device is more stable.
