The utility model discloses a two-way prestress weight reduction assembly type composite floor slab system. The two-way prestress weight reduction assembly type composite floor slab system comprises a pre-tensioning prestress prefabricated concrete bottom plate, weight reduction blocks, cast-in-place concrete ribs and post-tensioning prestress steel bars. Longitudinal prestressed load-bearing steel bars and transverse distribution steel bars are arranged in the pre-tensioned prestressed precast concrete bottom plate. A concrete reinforcing rib or a steel truss reinforcing rib or a steel and concrete combined structure reinforcing rib is arranged on the concrete bottom plate; the weight reducing blocks are laid on the pre-tensioned pre-stressed precast concrete bottom plate, and the weight reducing blocks are spaced by a certain distance. A plurality of pre-tensioned pre-stressed precast concrete bottom plates are assembled together, and concrete ribs are formed after the weight reducing blocks are cast in place. The prestressed steel bars are post-tensioned in the concrete ribs, and after the concrete reaches the strength, the steel bars are tensioned to form post-tensioned prestressing force to form bonded or unbonded prestressing force. According to the utility model, the bidirectional rigidity of the floor system is consistent, the bidirectional force transmission performance and the bidirectional anti-cracking effect are better, the integrity of the floor system is better, and more steel materials are saved.

The utility model relates to the technical field of signboard, specifically disclose a angle adjustable signboard, including base, the top surface mounting of base has the mounting frame, the inner chamber middle part of mounting frame installs the mounting panel, the mounting panel end face and bottom are evenly rotatory and set up a plurality of connecting shafts between mounting frame respectively, the outer wall on connecting shaft installs the signboard, the top surface of mounting panel evenly distributes a plurality of positioning piece, the both sides of two connecting shafts in the same vertical direction are close to each other respectively and are provided with adjusting assembly, the utility model discloses a angle adjustable signboard is provided with mounting panel, positioning piece, connecting shaft and signboard, and in the process of device use, realizes the mutual separation between multiple signboards in the gale weather through the mutual cooperation between above -mentioned structure, reduces the integrity of device, reduces the wind area and stress, thereby reaches the effect that reduces the stress of device, improves device stability and security.

The present application relates to the technical field of suspension bridge, and particularly relates to an anchoring system and a design method thereof, the anchoring system comprising a composite saddle and an anchorage, a main cable is connected with the anchorage through the composite saddle, a first front anchoring surface of the anchorage close to the composite saddle is in a spherical shape, the main cable is diverged into a plurality of strands through the composite saddle, and the strands are radiated from the composite saddle and connected on the first front anchoring surface. By setting the first front anchoring surface of the anchorage in a spherical shape, the stress increment of each strand is consistent when the composite saddle is displaced and slipped, and the consistency of the stress of the main cable is ensured. Further, by setting the first front anchoring surface in a spherical shape, the adjusting displacement of the composite saddle is not limited, that is, the stress level among the strands of the main cable is consistent under any displacement of the composite saddle, the stress adjusting step of the strands in the construction process is cancelled, the stress state of the main cable is ensured, and the uniform stress of the main cable is further ensured.

The utility model belongs to the technical field of water conservancy project protection, and relates to an ice-pushing-resistant heat absorption floating ball device for a reservoir in a cold region. Comprising a plurality of floating balls located on the water surface, and the floating balls are attached to form a floating cover layer; the floating ball is a hollow ball body and comprises an upper hemisphere and a lower hemisphere; the upper hemisphere is a light-transmitting layer; the lower hemisphere is a heat absorption layer; and the mass of the lower hemisphere is greater than that of the upper hemisphere. The device completely depends on solar energy to autonomously operate, has the advantages of zero carbon emission, low operation and maintenance cost and the like, and is particularly suitable for winter protection requirements of reservoirs in remote cold regions.

The invention discloses a two-way prestress overlap-reducing composite floor system which comprises a pre-tensioning prestress precast concrete bottom plate, weight reducing blocks, cast-in-place concrete ribs and post-tensioning prestress steel bars. Longitudinal prestressed load-bearing steel bars and transverse distribution steel bars are arranged in the pre-tensioned prestressed precast concrete bottom plate. A concrete reinforcing rib or a steel truss reinforcing rib or a steel and concrete combined structure reinforcing rib is arranged on the concrete bottom plate; the weight reducing blocks are laid on the pre-tensioned pre-stressed precast concrete bottom plate, and the weight reducing blocks are spaced by a certain distance. A plurality of pre-tensioned pre-stressed precast concrete bottom plates are assembled together, and concrete ribs are formed after the weight reducing blocks are cast in place. The prestressed steel bars are post-tensioned in the concrete ribs, and after the concrete reaches the strength, the steel bars are tensioned to form post-tensioned prestressing force to form bonded or unbonded prestressing force. According to the device, the consistency of the two-way rigidity of the floor system can be achieved through the two-way prestress, the two-way force transmission performance and the two-way anti-cracking effect are better, the integrity of the floor system is better, and more steel materials are saved.
