The invention relates to a plastic building template which comprises a planar main body plate and a strengthening rib positioned on one side of the planar main body plate, wherein the planar main body plate and the strengthening rib are produced by a solid plate which is formed by one-step molding of a PVC (polyvinyl chloride) foam material, the Vicat softening temperature of the solid plate is 97 DEG C, the elastic modulus is 3000, and the anti-bending degree is 60MPa. The plastic building template is light in weight, high in strength and surface smoothness and friction-resistant, is easy to clean, has no deformation, and can be cut and nailed arbitrarily according to needs without affecting the reuse of the template almost; any combination and supporting structure can be completed alone; square lumbers do not need to be attached to the back surface of the plastic building template to improving the strength of the template; and the material of the template can be recycled. The plastic building template is easy to process and manufacture, and the plastic building template further has the characteristic of one-step demolding and molding, and the filling of a hollow part and the re-strengthening problem of the side surface of the template do not need to be considered.

The invention discloses a fire-resistant cable bridge. The fire-resistant cable bridge comprises a bridge main body, a plurality of heat dissipation holes are formed in the side wall of the bridge main body, and a fireproof layer is fixedly attached to the inner wall of the bridge main body. A fireproof sliding plate for fire retardance and thermal insulation is arranged, and the bottom end of thefireproof sliding plate is clamped in the sliding groove. A fire retarding mechanism is arranged, and the fire retarding mechanism comprises a fixed wheel, a temperature sensing cavity and a push rod; a temperature sensing cavity is fixed on the bottom wall of the outer side of the bridge main body; a temperature sensing expansion piece is arranged in the temperature sensing cavity; the temperature sensing expansion piece is heated to expand; the push rod can be pushed, and then the conical side surface of the push rod head can push the fixed wheel so as to drive the fireproof sliding plate to slide and then seal heat dissipation holes, therefore, in case of a fire, high temperature can be automatically sensed to seal the cable bridge, and the fireproof layer in the bridge main body is used for stopping fire and insulating heat; and the fireproof sliding plate can be pulled to slide and reset under the action of the elastic force of the reset spring, so that the cable bridge has ventilation, heat dissipation and fire resistance, and can be automatically reset without influencing repeated use.

The invention relates to the filed of concrete pump truck manufacturing, in particular to a nondestructive technology for disassembling a landing leg pin shaft in the concrete pump truck remanufacturing process. The technology comprises the following steps that (1) drilling is conducted on the middle of a shaft sleeve with a copper sleeve; (2) a positioning pin is inserted into a hole, and the shaft sleeve and the landing leg pin shaft which relatively move originally are locked; (3) a landing led is swung, the landing leg pin shaft and the corrosion portion, without the copper sleeve, of the shaft sleeve are loosened; (4) the positioning pin is taken out; (5) the landing leg pin shaft is taken out. The nondestructive technology for disassembling the landing leg pin shaft in the concrete pump truck remanufacturing process is easy to carry out, gives a new life cycle of the landing pin shaft and a new life cycle of the shaft sleeve, improves landing leg pin shaft disassembling production efficiency by 70% and solves production bottleneck problems.
