The invention discloses a pressure dispersion type yielding anchor cable. The pressure dispersion type yielding anchor cable comprises an inner anchoring section, a free section and an outer anchoring section, wherein the inner anchoring section comprises multiple levels of inner anchoring bearing bodies; n is an integer not less than 2; each inner anchoring bearing body comprises a bearing plate, a sealing shell and at least two yielding anchorage devices arranged between the bearing plate and the sealing shell; and a constant-resistance body of each yielding anchorage device is connected with an inhaul cable which passes through the bearing plate. The anchor cable disclosed by the invention can prevent a single inhaul cable from being snapped efficiently when over-great bearing force is applied to the inhaul cable, the loading capability of the whole yielding anchor cable after resisting earthquake is not changed, and the yielding anchor cable can be stretched-drawn integrally for once, so that convenience is provided for construction; a dispersion type anchoring way is adopted, so that the size of a drilling hole is small and good economical efficiency is obtained; and the pressure dispersion type yielding anchor cable, disclosed by the invention, is suitable for multiple stratum conditions and in particular for the anchoring of rock soil in earthquake regions and high-pressure deformation conditions.

The invention provides a fruit packaging box for logistics transportation. The fruit packaging box comprises an outer box and an inner box located in the outer box; the outer box is composed of an outer box body and an outer box cover located at the top of the outer box body; the inner box is composed of an inner box body and an inner box cover located at the top of the inner box body; a pluralityof springs are arranged between the inner surface of the outer box and the outer surface of the inner box, and a cavity is formed and internally provided with a plurality of ice bags; the inner box is a foam box; and the wall of the outer box is composed of an inner layer, an outer layer and a damping mechanism located between the inner layer and the outer layer. According to the fruit packagingbox, the two-box form is adopted, the inner box is the foam box and used for storing fruits, the springs are arranged between the inner box and the outer box and achieve the vibration reduction effect, and moreover, the wall of the outer box is provided with an interlayer which is internally provided with the damping mechanism. The fruit packaging box has a certain damping effect, the cavity formed between the outer box and the inner box is internally provided with the ice bags and can achieve the effect of cooling the inner box, and the fruits can keep fresh advantageously.

The invention discloses a beam-column anti-seismic connecting joint and a connecting method thereof, and the problem of brittle fracture is solved. The beam-column anti-seismic connecting joint is used for connecting of a steel column and an I-shaped steel beam, and a first space and a second space are arranged on connecting parts of the two ends of the steel beam; a laminated component is arranged in the first space, and a grouting groove is formed in the second space; a transition connecting piece is fixed on the steel column, and an inserting groove of the transition connecting piece is a U-shaped groove structure with upward opening and is composed of a bottom plate and side plates on the two sides; a connecting part is connected with the inserting groove in an inserted mode, and high strength long bolts are fixed on the two side walls of the inserting groove; and high strength long bolts pass through a strip hole I in a steel sheet, a strip hole II in a beam web and a pin hole in a friction slice. By means of grouting, rigid connecting is formed between the steel beam and the transition connecting piece. Under the action of an strong earthquake, concrete blocks are damaged and crushed, then flexible connecting is formed between the steel beam and the transition connecting piece through the laminated component and the concrete blocks.

This application relates to a concrete prefabricated component, which includes several component bodies, and several component bodies are stacked along the thickness direction, and each side wall of the component body is respectively provided with locking grooves. The corresponding locking grooves on the main body are all connected, and locking pieces are respectively arranged in the locking grooves. This application has the effect of standardizing the production of the component body, that is, the component body can be mass-produced, thereby reducing the manpower and material cost of making various molds.

The invention discloses a steel structure beam column connecting joint and a connecting method thereof, and aims at solving the problem that existing connecting joints are prone to brittle fracture. The steel structure beam column connecting joint and the connecting method thereof are used for steel column and I-shaped steel beam connection. Connecting parts at the two ends of the steel beam are afirst space and a second space. A transition connecting piece is composed of a steel plate and an inserting and connecting groove and is fixed to a steel column, and after inserting and connecting ofthe inserting and connecting groove and the steel beam, a joint structure is formed. A platy spring assembly is arranged in the inserting and connecting groove between the connecting parts and a bottom plate. A steel cable is arranged between the steel beam and the transition connecting piece. The part between the second space and the side wall of the inserting and connecting groove is grouted. Under the action of the violent earthquake, concrete blocks are crushed in a damaged manner, then the steel beam and the transition connecting piece are flexibly connected, and the relative movement capability is achieved; under the action of the platy spring assembly and the action of the earthquake, high-frequency reciprocating vibration is conducted, and most of earthquake energy can be consumed; and connecting point brittle fracture can be effectively avoided, and the earthquake resisting function is achieved.
