A kind of novel C LT plate of zigzag interlayer gluing mode, the novel C LT plate are made of sandwich layer and surface layer, and sandwich layer and surface layer all have corresponding recessed (convex) slot；CLT plate is generally all formed by odd-level panel gluing, intermediate core layer is bonded with two adjacent surfaces with recessed (convex) slot both sides sandwich layer using two sides with convex (recessed) chute panel, it is successively bonded according to the panel number of plies needed for engineering in this way, until last surface layer is bonded using unilateral recessed (convex) slot with adjacent sandwich layer；During being bonded herein, it is chimeric together to make groove between each adjacent panels and tongue (tongue with groove), and use anhydride cured epoxy orthogonal glued together between each deck panels.The present invention is had the advantage that compared with existing glued mode and is fitted between each laminate using tongue and groove, can make to connect between plate and plate closer, it is not easy to peel off, to improve the overall performance of CLT plate.
Description
Technical field
The invention belongs to buildings and technical field of buildings, are related to building element, in particular to a kind of zigzag interlayer is glued
The novel C LT plate of mode.
Background technique
Application and research of the CLT panel in building structure are constantly subjected to favor both domestic and external in recent years.CLT plate is to pass through
Orthogonal gluing forms between adjacent panels, all has the wet performance that rises of identical drying shrinkage in material primary and secondary direction, therefore its size is steady
Qualitative is 12 times of solid wood and other laminated wood band direction dimensional stabilitys；Due to the particularity of its group of embryo, shearing is rolled
Performance is lower；Compared with traditional Light-frame building, the sectional dimension of CLT building element is larger, surface carbonation shape when burning
At heat-insulating protective layer, its bearing capacity in a fire is effectively raised；CLT can carry out large-scale production and pre- in factory
It makes, and can be processed into floorboard, beam, column and the shingle nail of any suitable size door-window opening specification according to engineering design requirements,
These components can directly be transported to live Fast Installation, greatly shorten the installation period of building, and be a kind of environmentally protective knot
Structure component.The CLT hardened structure more universal for existing application, rate of utilization of strength and other some mechanical performance indexs are simultaneously
Insuperior and present most of glued board is directly to form panel tiling gluing, glued under prolonged load action
The adhesive property sharp fall between layers of plate, or peeling is generated, influence the overall performance of structure.
For the above problems faced, domestic and foreign scholars have also carried out more research.Its direction studied can be divided mostly
For the following aspects.First aspect studies the type of adhesive used in gluing between layers, such as uses asphalt mixtures modified by epoxy resin
The others adhesive such as rouge adhesive or synvaren, although its adhesive stability is all preferable, it is harmful
Substance (such as formaldehyde) content is higher and uneconomical, and overlong time, is also easily easy to appear aging phenomenon, makes to hold between layers
It is easy to fall off.In gluing procedures, one layer of special binder course is arranged in the second aspect between the layers, such as some scholars exist
One layer or multilayer FRP is added between layers, although its overall performance that can increase CLT plate, cost are excessively high.Third
A kind of embeded-fixed device is arranged in a aspect between adjacent laminate, such as some scholars are arranged relatively in the adjacent surface of adjacent panels
Reinforcing bar is arranged between corresponding groove in the groove answered, and is combined together adjacent deck panels firmly, although its method can
Effectively overcome disengaging between layers, but its gluing technique and design process are complex, and uneconomical.
Summary of the invention
In order to overcome the disadvantages of the above prior art, the purpose of the present invention is to provide a kind of zigzag interlayer gluing modes
Novel C LT plate, not only can guarantee prevents the removing of glued board between layers under action of long-term load, but also can make gluing technique
Simplify with design process, and economic and environment-friendly.
To achieve the goals above, the technical solution adopted by the present invention is that:
A kind of novel C LT plate of zigzag interlayer gluing mode, including upper layer 1, cutting optimal 3 and middle layer plate 2, the core

The lower surface of layer 1 is provided with groove 1 that can be chimeric with the matching of tongue 1, and the upper surface of cutting optimal 3 is provided with can be with institute
State the chimeric groove 24 of the matching of tongue 25；
When for multilayer, the upper surface of top layer's middle layer plate 2 is provided with several tongues 1, the following table of lowest level middle layer plate 2
Face is provided with several tongues 25, is fitting to connection between adjacent layer middle layer plate 2 with tongue and groove, the lower surface setting of the upper layer 1
Have a groove 1 that can be chimeric with the matching of tongue 1, the upper surface of cutting optimal 3 be provided with can be matched with the tongue 25 it is embedding
The groove 24 of conjunction.
The middle layer plate 2 uses fast growing wood, and such as poplar or willow, the laminate 1 above and following laminate 3 use iron
China fir, and glued composition CLT plate orthogonal with middle layer plate 2.
It is described above between laminate 1 and middle layer plate 2, between adjacent layer middle layer plate 2 and middle layer plate 2 and following laminate 3 it
Between, including between each tongue and groove, it is all made of that anhydride cured epoxy is orthogonal glued together, i.e., the fiber side of each adjacent layer
To being mutually perpendicular to, and pass through pressurization, the stability and globality of Lai Zengjia component.
The upper surface of described laminate 1, following laminate 3 and middle layer plate 2 are to select suitable quantity and ruler according to scantling needs
Very little specification wood combination forms.
The tongue 25 and tongue 1 can use any suitable shape, corresponding groove 24 and groove 1
Shape also accordingly changes, need to only guarantee that corresponding groove can be completely fitted with tongue together with.That is, no matter concave-convex
What shape slot uses, tongue and groove and middle layer plate 2 between adjacent middle layer plate 2 and the up and down tongue between surface layer with it is recessed
Slot should all be entrenched togather.
The shape of the tongue 25 and tongue 1 and corresponding groove 24 and groove 1 can be according to requirement of engineering
It is determined with easy making process.The fast growing wood panel number of plies can be adjusted according to requirement of engineering and the demand of element bearing capacity.
The tongue 25 and tongue 1 and corresponding groove 24 and groove 1 are according to scantling and bearing capacity
It needs to determine its corresponding geometric dimension size.
Compared with prior art, the beneficial effects of the present invention are: a kind of zigzag interlayer gluing mode of the invention it is new
Type CLT plate is bonded between each layer of glued board using notch, the fastness combined between plate and plate is increased, to improve
The globality of CLT plate, and its gluing technique and design process are simple, it is economic and environment-friendly.
