This invention belongs to the field of modular prefabricated floor slab technology, and more particularly to a modular prefabricated building floor slab structure, including a floor slab body. Multiple locking mechanisms and multiple U-shaped reinforcing bars are equally spaced on both sides of the floor slab body. The locking mechanisms and U-shaped reinforcing bars on both sides of the floor slab body are centrally symmetrically distributed. Each locking mechanism includes a box detachably mounted on the floor slab body. Inside the box is a unidirectional rotating column, and two centrally symmetrically distributed levers are fixedly mounted on the side of the rotating column. This invention, by setting multiple sets of cooperating locking mechanisms and U-shaped reinforcing bars between adjacent floor slab bodies, applies active traction force to the slabs during splicing, creating reliable pre-stress at the joint, transforming "passive filling" into "active pressing," effectively overcoming the problem of penetrating micro-cracks caused by inconsistent drying shrinkage deformation in traditional post-cast strips.

The motor drives the eccentric wheel to rotate, the transmission swing arm drives the sliding block to slide between the two guide blocks in the rotating process of the eccentric wheel, the cutter holder pressing block fixes the cutter holder and the cutter set main plate into a whole, and only the height of the cutter set main plate needs to be adjusted during installation. And the problem of height difference between the cutter clamp and the cutter group main plate in the adjusting process can be effectively avoided, so that friction and noise are reduced, and the service life of the cutting assembly is greatly prolonged.

The utility model discloses a direct-touch type ground splicing structure, and relates to the field of ground stone installation, the direct-touch type ground splicing structure comprises a fine aggregate concrete layer, a thick daub bonding layer and stone plates which are sequentially laid on a reinforced concrete floor layer from bottom to top, and expansion joint strips are arranged between the stone plates; an expansion joint strip is arranged on the surface of the stone plate, an auxiliary assembly used for auxiliary positioning is arranged outside the expansion joint strip, an arc groove is formed in one side of the surface of the stone plate, and arc plates matched with the arc groove are fixedly connected to the two sides of the expansion joint strip correspondingly. When the supporting plate is located in the positioning piece, the supporting plate is opened through the elastic force of the torsional spring and abuts against the inner wall of the positioning piece, the expansion joint strip is clamped, the position of the expansion joint strip is more stable, and position deviation caused after the expansion joint strip is impacted can be prevented.

The utility model relates to the technical field of faucet elbow machining, and discloses a numerical control lathe fixture for faucet elbow machining, which comprises a support part and a control switch, the surface of the support part is slidably connected with a fixture lower part, the two sides of the support part are provided with accommodating holes, the interiors of the accommodating holes are fixedly connected with limiting assemblies, and the limiting assemblies are fixedly connected with the support part. Connecting plates are fixedly connected to the edges of the two sides of the lower clamp part correspondingly, and adjusting assemblies are fixedly connected to the surfaces of the two connecting plates correspondingly. According to the numerical control lathe clamp for machining the faucet elbow, through the arrangement of the clamp lower part, the adjusting assembly, the clamp upper part and the micro rolling wheels, the effect of clamping pipe bodies with different thicknesses is achieved, in addition, the pipe bodies are convenient to move, and the situation that when the faucet elbow is machined, the pipe bodies need to move in the clamp, and the machining efficiency is improved is avoided. And the interior of the clamp can scratch the pipe body, and the pipe body is difficult to move in the clamp easily, so that the practicability and the adaptability of the clamp in use are improved.
