Description
Technical field
The utility model relates to a kind of tri- layers of grid coextruded plastic building templates of PP.
Background technique
The building template that the architectural engineering of various regions generally uses at present be divided into steel form, bamboo blanket template, PVC template and
Plywood form.Wherein steel form is not only heavy and construction in there are biggish security risks；Bamboo blanket template and glued template die
Plate itself is by the compression of multilayer veneer, is bonded, easy to crack after infiltration, and contains formaldehyde using what is be harmful to the human body in production
Glue；Although PVC building template, which uses foaming technique, makes weight saving, the property of PVC itself determines building template
Brittleness it is bigger and intensity is small.Therefore, there is hollow plastic building template light-weight, that intensity is high in the demand for answering market,
However the multiplicity of existing hollow template above and below layer and central hollow out interlayer is poor, hollow out position intensity is low, and hollow out position pours into
It is serious to hinder completion rear mold demoulding after concrete and solidification, in addition, the physics to expand with heat and contract with cold since plastic material is generally existing
Property, template is continuously in the case of general plate, the hard extruding that plate seam crossing is generated due to deformation, easily caused by damaged template or de-
Out.
