Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments of the present invention may be combined with each other without conflict.
It is to be understood that such description is merely exemplary and is not intended to limit the scope of the present invention.
The following describes a close-splicing bidirectional prefabricated laminated plate structure provided by some embodiments of the present invention with reference to the accompanying drawings.
The first embodiment is as follows:
referring to fig. 1 and 3, the upper plywood body 100 and the lower plywood body 200 are provided, the lower plywood body 200 includes a lower plate body 201 and at least two engaging teeth 202 provided on the lower plate body 201, the upper plywood body 100 includes an upper plate body 101 and an engaging groove 102 opened in the upper plate body 101, and the engaging groove 102 is configured to be fitted to the engaging teeth 202.
Specific, present prefabricated superimposed sheet is when using, the concrete has all been pour at the top, when a plurality of prefabricated superimposed sheets splice, the easy crack that produces of concatenation department, lead to the compactness variation of connecting between the prefabricated superimposed sheet, thereby influence prefabricated superimposed sheet's result of use, and present prefabricated superimposed sheet is the integral type mostly, it is inconvenient to its transportation and construction, through being provided with superimposed sheet main part 200 down, with the top of going up superimposed sheet main part 100 assembly superimposed sheet main part 200 under, constitute complete prefabricated superimposed sheet, when splicing between a plurality of prefabricated superimposed sheets, through pegging graft between meshing tooth 202 and meshing groove 102, the fastening force that produces when utilizing to peg graft, thereby prevent that the junction between a plurality of prefabricated superimposed sheets from producing the crack.
The cross section of the meshing tooth 202 is in a parallelogram shape, and an included angle between the meshing tooth 202 and a horizontal line is eighty-five degrees, so that the meshing tooth 202 and the meshing groove 102 are connected in an inserting mode to form a certain inclination, and when the meshing tooth is influenced by external force, the meshing tooth is not easy to separate from the meshing groove.
Example two:
the lower laminated board main body 200 further comprises positioning columns 203 fixed on the lower board body 201, the upper laminated board main body 100 further comprises positioning holes 103 formed in the upper board body 101, the positioning holes 103 are inserted into the positioning columns 203, the number of the positioning columns 203 is at least two, and the number of the positioning holes 103 corresponds to that of the positioning columns 203.
Specifically, according to the first embodiment, the lower laminated slab main body 200 and the upper laminated slab main body 100 are assembled to form a complete prefabricated laminated slab, the positioning holes 103 are inserted into the positioning columns 203 by providing the positioning columns 203, so that the lower laminated slab main body 200 and the upper laminated slab main body 100 are connected, and the positions of the lower laminated slab main body 200 and the upper laminated slab main body 100 are defined.
