Description
Technical field
The utility model relates to a kind of building template, is specifically related to a kind of Plywood for concrete form.
Background technology
Plywood for concrete form is the concrete structure engineering requisite instrument of constructing, and it directly has influence on the economic benefit of quality, speed, cost and the construction enterprises of engineering construction.Plywood for concrete form have breadth large (length and width of general Plywood for concrete form are of a size of 2440 * 1220mm, and thickness is no more than 24mm), piece few, good from heavy and light, easily processing, integral rigidity, water the features such as the concrete surface building up is smooth, service life is long.Nowadays Plywood for concrete form has become a kind of welcome, application template material very widely.Conventional concrete blinding, is suppressed and is formed under the condition that heats or do not heat by the crisscross slab being made into of grain direction with the veneer after gluing.Conventional have a 9-15 layer glued board.Glued board can improve timber utilization rate, is a main path saving timber.
In prior art, the production technology of Plywood for concrete form is: first, log, through rotary-cut, forms veneer, and described veneer is the laminar timber that half-round cut, slicing or saw method processed are produced.This rotary-cut technology gets the maximum degree of application log.Veneer is generally to contain very juicyly, and the plank with moisture is unfavorable for the processing in later stage, so after rotary-cut, plank can dry, if require highlyer for efficiency, the general method of using is to make to Tumble Dry.Gluing, covers glue to the aspect up and down of template, makes template have the outstanding characteristics such as the anti-combustion of waterproof.Described glue is phenolic resin glue or urea-formaldehyde resin adhesive.Template after gluing is carried out to typesetting, plank is arranged according to specific rule, wood grain should be crisscross, so that the strength increase of building template, general one deck building template is pressed into by several layers of plank, and inside is the core material of 2 millimeters, and upper and lower two-layer is the cladding of 1.2 millimeters, this arrangement mode both can make building template reach certain intensity, also can guarantee the characteristics such as the resistance to combustion of its waterproof.Compacting, the compacting of building template need to be colded pressing and make to produce certain connection between core material through repeatedly processing, and the shape of building template is tentatively shaped.The process of hot pressing can make the glue that covers between core material thoroughly glue together, and deburring, after being pressed into, is used the modification of Sawing machine to template machine molded dimension.After deburring finishes, also should on the new edge of shearing out, use glue to carry out edge sealing.General Plywood for concrete form is of a size of 2440 * 1220mm.Through after above processes, Plywood for concrete form has just been made.Traditional Plywood for concrete form, longitudinal and laterally easily distortion under the larger environment of the temperature difference, thereby the correct shape of the concrete of very difficult assurance cast etc., leakiness concrete grout, service life is also short.
Utility model content
The purpose of this utility model is that a kind of a kind of casting concrete template that can overcome above-mentioned shortcoming will be provided, and has cost low, the advantage of long service life.
The technical solution adopted in the utility model is: a kind of Plywood for concrete form, is characterized in that: described Plywood for concrete form comprises template body layer, back-up coat.

The width of described back-up coat is not less than 2 times of width of the plywood panel in template body.
On the upper side of described upper back-up coat, be pasted with the film paper of waterproof, corrosion-resisting function, on the downside of described lower back-up coat, be pasted with the film paper of waterproof, corrosion-resisting function.
Described plywood panel is for cutting the plywood panel that gets off from whole glued board.Described whole glued board can be fresh processed glued board, can be also the old glued board reclaiming after construction.
Further, the width of described plywood panel is 5-50cm.Length, the thickness of described plywood panel are not limit.
Further, the width of described plywood panel is: 15-30cm.Length, the thickness of described plywood panel are not limit.
Further, the equal and opposite in direction of described plywood panel, is carved with the concave station that is " L " shape on one group of adjacent edge of its upper side, and described concave station connects described limit; One group of adjacent edge that its downside is relative is also carved with the concave station that is " L " shape, and described concave station connects described limit; Adjacent plywood panel is combined by overlap joint.
Further, when two adjacent plywood panels splice, wherein the butt joint edge of a plywood panel is provided with some fins, and the butt joint edge of another piece plywood panel is provided with the groove that shape adapts with it, and the combination by described groove and fin is connected together the two.
Further, end face and the distance between the upper side of plywood panel of described fin end are less than the distance between its root end face and the upper side of plywood panel, or
End face and the distance between the upper side of plywood panel of described fin end are greater than the distance between its root end face and the upper side of plywood panel.
Further, described fin has 1-4 bar.
Further, on the Mosaic face of described plywood panel, be coated with glue.
Further, when described template body layer is composited by multilayer body layer, between at least one group of its adjacent body layer, be provided with body back-up coat;
Described body back-up coat comprises at least two-layer wood grain veneer glued together arranged vertically each other, and described veneer is the laminar timber that half-round cut, slicing or saw method processed are produced; Or
Described body back-up coat comprises the veneer glued together that at least one deck wood grain is arranged in parallel, and described veneer is the laminar timber that half-round cut, slicing or saw method processed are produced.
The beneficial effects of the utility model are: because template body layer is composited by one or more layers body layer, the plywood panel that the glued board that body layer is rectangle by cross section cuts is spliced, owing to connecting by splicing between these plywood panels, when the construction environment temperature difference is larger, form shrinkage joint, therefore whole Zhang Shimu template or the glued board of the utility model template in compared to existing technology, its temperature deformation amount is much smaller, solved at one stroke in prior art template the temperature difference compared with under overall situation longitudinally with laterally easily distortion, the correct shape of the very difficult concrete that guarantees cast etc., leakiness concrete grout, the difficult problem that service life is short.Plywood panel in the utility model is whole the plywood panel that glued board cuts, these plywood panels can be produced from fresh processed whole glued board, also can from constructing, reclaim whole glued board produces, while particularly using the rear recycled materials of construction, cost is low and can reclaim waste resource, has good economic benefit and social benefit.
