The present invention proposes a kind of high-strength building formwork free of demolition, including wire side, core, connection structure；The wire side is arranged in the surface of core, and insertion core surface depth is not more than 3 millimeters；By being made with meshed grid cloth, the core is solidified the wire side by being mixed into gypsum slurry including high strength gypsum powder, fiber, additive and water；The fibre length is 0-16mm, and the weight percent of fiber and core is 0.05%-0.1%, and the periphery of template core is arranged in the connection structure, for being connected with each other between template and the connection of external fixation device and template.Fiber is added in core, increases the intensity of template, avoid because intensity of vibrating is big and the mould that occurs rising leads to the phenomenon of template breakage, make template form one with building element using gypsum and the good binding performance of concrete, improve efficiency saving cost.
Description
Technical field
The invention belongs to building field, in particular to a kind of height free of demolition used when casting concrete in construction
Intensity building template.
Background technique
In construction, since structure needs, generally requires to carry out cast-in-site to certain building elements, be poured
When, in the template of the periphery installation respective shapes of casting component, inner cavity identical with Components Shape is formed, is cast into the lumen
With the concrete of mobility and other slurries；In existing casting process, peripheral template mostly use greatly timber or
The template of steel production, needs to set up template before casting, needs to dismantle template after casting complete, seriously affect architectural engineering
Construction period, and need to waste many timber and steel plate, cause building cost to increase.In view of the deficiencies of the prior art, it sends out
A kind of bright building template free of demolition, but in concreting process, need to vibrate by vibrating head, in process of vibrating,
Since vibrating time and intensity are different, building template breakage free of demolition is caused to deform.
Summary of the invention
For the above problem existing for formwork for placing in existing construction, the present invention proposes a kind of high intensity free of demolition
Building template, it is characterised in that: including wire side, core, connection structure；The wire side is arranged in the surface of core, insertion
Core surface depth is not more than 3 millimeters；The wire side with meshed grid cloth by being made, and the core is by including high-strength
Degree land plaster, fiber, additive and water are mixed into gypsum slurry and solidify；The fibre length is 0-16mm, fine
Dimension and the weight percent of core are 0.05%-0.1%, and the periphery of template core is arranged in the connection structure, is used for template
Between be connected with each other and external fixation device and template connection.
Further, the high strength gypsum powder is by including alpha semi-hydrated gypsum or β type building gypsum or anhydrous type gypsum
It is made.
Further, the high strength gypsum powder includes the mixture of 5%-70% semi-hydrated gypsum and anhydrous III type gypsum,
The anhydrous II type gypsum of 20%-80%, other compositions are impurity；The mixture of the semi-hydrated gypsum and anhydrous III type gypsum is
The semi-hydrated gypsum that the anhydrous III type gypsum that ardealite calcination temperature is generated at 200 °C -360 °C and 130 ° -200 °C whens generate
Mixture；This is the mixture formed in ardealite calcination process；The anhydrous II type gypsum, is to calcine ardealite
The anhydrous II type gypsum generated when to 360 °C；Other substances contained inside ardealite when the impurity is ardealite calcining
The impurity formed after calcining；Semi-hydrated gypsum, anhydrous II type gypsum, anhydrous III type gypsum and the impurity is all powdery.
Further, the additive includes one of mountain flour, fine sand, perlite, vermiculite, EPS particle or a variety of
Mixing, water-reducing agent and foaming agent.
Further, the foaming agent include surfactant, it is dodecyl sodium sulfate, lauryl sodium sulfate, double
One or more mixing of oxygen water.
Further, the fiber is one of alkali-resistant glass fibre, glass fibre, nylon, plant fiber or more
Kind mixing, the plant fiber is sawdust, sawdust, plant stalk crushed material.
Further, the connection structure is slot hole either protrusion.
Beneficial effect
The beneficial effects of the present invention are fiber is added in core, increases the intensity of building template free of demolition, avoids because of vibration
Smash that intensity is big and the mould that occurs rising causes building template free of demolition damaged, it is good using gypsum and concrete and other construction materials
Binding performance makes template and building element form one, simultaneously because gypsum has lightweight, pollution-free, heat-resisting, heat conductivity
The characteristic of energy difference, can be attached to building element surface and form heat-insulated and decorative layer, reduce successive projects amount.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention
1, wire side, 2, core, 3, connection structure, 4, fiber.
Specific embodiment
Below with reference to embodiment, the present invention is described in further detail.
Embodiment 1
As shown in Figure 1, a kind of high-strength building formwork free of demolition, including wire side, core, connection structure；The wire side 1 is arranged
In the surface of core 2, insertion 2 case depth of core is not more than 3 millimeters；The wire side 1 is fabric with meshed grid
At the core 2 is solidified by being mixed into gypsum slurry including high strength gypsum powder, fiber 4, additive and water；
The additive includes one of mountain flour, fine sand, perlite, vermiculite, EPS particle or a variety of mixing, water-reducing agent and foaming
Agent, the foaming agent include surfactant, dodecyl sodium sulfate, lauryl sodium sulfate, one kind of hydrogen peroxide or more
Kind of mixing, the fibre length is 16mm, and the weight percent of fiber and core is 0.05%, and the fiber 4 is alkaline-resisting glass
One of glass fiber, glass fibre, nylon, plant fiber or a variety of mixing, the plant fiber are sawdust, sawdust, plant
The periphery of template core 2 is arranged in object bar stem crushed material, the connection structure 3, for interconnection between template and outside
The connection of fixed device and template, the attachment device are slot hole either protrusions.
The high strength gypsum powder is described by including that alpha semi-hydrated gypsum or β type building gypsum or anhydrous type gypsum are made
High strength gypsum powder include 5%-70% semi-hydrated gypsum and anhydrous III type gypsum mixture, the anhydrous II type gypsum of 20%-80%,
