The utility model discloses a prestressed concrete structure hole reinforcing connecting device, which belongs to the field of concrete structure design and construction, and comprises a concrete beam, and a hole is arranged in the concrete beam. Meanwhile, the connecting prestressed steel strands are arranged at the circular hole, the hole is surrounded by the connecting prestressed steel strands, the effect of enhancing the shear bearing capacity of the net section of the beam at the hole can be achieved, and meanwhile the connecting prestressed steel strands comprise the horizontal prestressed steel strands and the hole prestressed steel strands; the reinforcing ribs on the periphery of the hole are extruded through the arc-shaped hole prestress steel strands, the effect of supporting multiple side ends of the hole can be well achieved, the supporting force of the hole is enhanced, the hole is more stable, the effect of reinforcing connection of a concrete hole structure is achieved, and later construction is more convenient.

The utility model provides a house building construction leveling device which comprises a first connecting rod and a second connecting rod which are horizontally distributed left and right, three sets of leveling structures which are distributed left and right at equal intervals are arranged in the second connecting rod, and a third connecting rod and a limiting rod are fixedly installed at the end, close to the first connecting rod, of the second connecting rod. The two sets of limiting rods are located on the two sides of the third connecting rod. According to the utility model, by designing the flatness measuring structure, when in use, the laser emitter is started, laser emitted by the laser emitter passes through the three groups of laser holes, and the insertion rod is pulled out, so that the scale can slide up and down in the second connecting rod, and then the lantern ring, the first connecting rod and the second connecting rod are rotated around the connecting shaft, so that the ground flatness is measured in a circle drawing manner; when the ground is uneven, the laser emitted by the laser emitter is blocked, at the moment, a worker can observe the scales on the scale to quickly obtain the uneven ground value, and later construction is facilitated.

The application relates to the technical field of building construction, in particular to a horizontal ALC plate outer window sill wall structure, the lower end of a main frame column is provided with a side straight plate and an ALC plate, the side straight plate is arranged on the inward side of the ALC plate, the end of the side straight plate and the end of the ALC plate are connected with the lower end side of the main frame column through L-shaped steel, the outward side of the side straight plate is provided with a plurality of connecting plates, the upper end and the lower end of the ALC plate are both provided with perforations, and the side straight plate and the ALC plate are connected through the connecting plates penetrating the perforations. The application can make up the height of the outer window sill wall with different design heights, so that the limitation of the installation height of the ALC plate during installation can be made up, the overall reinforcing requirement of the outer window sill wall is met, and the overall adaptability is improved.

The invention relates to the field of expressway construction methods, in particular to a mountainous area steep-cliff-crossing section bent cap construction structure which is characterized in that width piers, single-column piers and a bridge floor of a bent cap structure are combined, so that the arrangement position of the single-column piers is adjusted, the stability of the construction structure is realized, and the construction efficiency is improved. The bridge floor is arranged between a highway side and a cliff side, a pier structure is fixedly arranged at the bottom of the bridge floor, and the bridge floor is of a bent cap structure; the bridge pier structure comprises a single-column pier, a left width pier and a right width pier, the left width pier, the right width pier and the single-column pier are sequentially arranged in the cross section direction of the bridge floor, the single-column pier is close to one side of the cliff edge, and the bottom of the bridge floor is fixedly connected with the top faces of the left width pier, the right width pier and the single-column pier. The method is particularly suitable for road construction of cliff-crossing sections in mountainous areas.

The utility model discloses a kind of silt ground stratum deep foundation pit support structures, including baffle, adjusting assembly is provided between two described baffles, and the top of one of described baffles is fixedly installed with L-shaped plate, one side of the L-shaped plate is fixedly installed with driving motor, the output of the driving motor is fixedly installed with winding wheel, the inner wall of the L-shaped plate is rotatably connected with the winding wheel, and the outer end of the winding wheel is wound with measuring scale;The silt ground stratum deep foundation pit support structure is provided with driving motor, winding wheel, measuring scale and counterweight, driving motor is responsible for driving winding wheel rotation, and then realizes the winding operation of measuring scale, by adjusting, the length of measuring scale can be accurately controlled, the effect of counterweight is to make measuring scale vertically move downwards, to facilitate the depth of silt ground stratum deep foundation pit measurement, this process greatly facilitates staff to carry out later construction, and expand the application range of silt ground stratum deep foundation pit support structure.
