Description

Prefabricated superimposed sheet that dead weight is little and be convenient for stack and transportation deposits transportation support

Technical Field

The utility model relates to the technical field of building structures, in particular to a prefabricated composite slab storage and transportation support which is small in self weight and convenient to stack and transport.

Background

The laminated floor slab is an assembled integral floor slab formed by laminating prefabricated slabs and cast-in-situ reinforced concrete layers, and has the advantages of high integrity and rigidity, good crack resistance, no increase of the consumption of reinforcing steel bars, template saving and the like of the cast-in-situ floor slab. Meanwhile, the laminated slab moves the step of partial cast-in-place floor slabs to a factory, so that the working procedures are reduced and the construction period is shortened for a construction party.

At present, the laminated slab prefabricated slab is usually produced in a mode of being manufactured in a factory and assembled on site, and a storage rack of the laminated slab cannot be separated in the process. Meanwhile, the land for factories and construction sites is short, and the storage space of the laminated slab needs to be saved as much as possible. Therefore, stacking between storage racks is unavoidable, and the safety of stacking must be considered heavily. The transportation is also one of the most important links of superimposed sheet for the actual engineering, and the high of storage rack stand often can influence the current of vehicle, realizes that stand altitude mixture control can make things convenient for the superimposed sheet transportation. In addition, the detachability of the storage rack can save the storage space when the storage rack is empty. The existing storage rack scheme often does not consider the safety problem caused by the overlarge dead weight of the storage rack, the problem of the overlarge occupied storage space during no-load and the transportation limitation caused by the height of the upright column.

The existing connection node has the following defects: firstly, all the rod pieces are solid rods, and the dead weight is large; secondly, the upper layer and the lower layer are connected by the plug holes and the plug parts, so that the requirement of vertical stacking is met, but each layer can only be respectively lifted from top to bottom during lifting; thirdly, the storage rack is not detachable, and the utilization rate of the stacking space is not high when the storage rack is empty; finally, the frame height cannot be adjusted, and transportation is easily limited.

An effective solution to the problems in the related art has not been proposed yet.
