The utility model discloses through with mould is divided to two mould plates on, two mould plates all adopt multilayer thin plate plywood and are formed, and each layer thin plate fiber direction is staggered, can bear the pressure, impact force and other external force in the mould use process, reduces mould damage risk, and four edges of two mould plates all adopt angle iron package, and the corner is welded, guarantees that mould whole structure is complete, prolongs mould service life.

The utility model discloses an improved prefabricated T-beam temporary supporting device which comprises an adjustable lifting rod, one end of the adjustable lifting rod is detachably connected with a supporting mechanism, and the other end of the adjustable lifting rod is detachably arranged in a fixing mechanism in a penetrating and sleeved mode. The supporting mechanism comprises a supporting top plate; the lower end of the supporting top plate is connected with a supporting sleeve which is connected with the upper end of an adjustable lifting rod in a pluggable mode. The upper end of the fixing mechanism is in lifting movable fit with the adjustable lifting rod, and the lower end of the fixing mechanism makes contact with or is connected with the ground. And the adjustable operating part is arranged on the adjustable lifting rod in a penetrating and sleeving manner in a sliding manner and is used for manually completing lifting of the adjustable lifting rod in the fixing mechanism. The height adjusting device is compact in structure, rapid and convenient to adjust in height, small in occupied space and capable of being rapidly and easily installed on a T-shaped beam or a cross beam needing to be supported in a limited space, time and labor cost are saved, it is guaranteed that the T-shaped beam or the cross beam keeps stable in structure under the action of bearing gravity or other external force, and deformation or inclination is avoided.

The invention discloses a pre-positioning fast dismounting stock bin and method based on foldable fan-shaped bin sections.The stock bin is formed by connecting a plurality of fan-shaped bin sections from bottom to top, each fan-shaped bin section comprises an arc-shaped fan-shaped piece, the two side ends of each arc-shaped fan-shaped piece are hinged to one end of a straight face piece, and the other end of each straight face piece is hinged to the corresponding arc-shaped fan-shaped piece. The other ends of the two straight-face sheets are detachably connected with each other, and telescopic supporting rods are respectively connected between the two straight-face sheets and the arc-shaped sector sheet; positioning holes are formed in the connecting end faces of the upper fan-shaped bin section and the lower fan-shaped bin section respectively, and positioning pins are inserted into the positioning holes. On the basis of ensuring the transportation size, the positioning work is completed in advance in a processing plant, and only the folded bin body needs to be opened and fastened on site, so that the structural integrity of the bin body is ensured, and the on-site construction period is also shortened. Meanwhile, the folding bin body can be more convenient to maintain and replace the bin body in the future.
