Description

A kind of one assembly concrete Side fascia of the six directions

Technical field

The utility model relates to construction material, the utility model is specifically related to a kind of one assembly concrete exterior wall of the six directions Plate.

Background technique

For a long time, cast-in-place or brick masonry structure is widely used in exterior wall, and exterior-wall heat insulation common practice is external thermal insulation.Tradition Outside wall heat preservation is placed on thermal insulation material on the outside of exterior wall, and heat bridge is essentially eliminated, and is not take up indoor usable floor area, but has There is the defects of difficulty of construction is big, easy to crack, easy to fall off, durability is poor.Especially in recent years, external-wall heat-insulation material and exterior wall tile It falls off and often results in casualties, there is very big security risk, social influence is more severe.

Currently, country starts to promote assembled architecture, according to " about the instruction for greatly developing assembled architecture ", " strive the time with 10 years or so, the ratio for making assembled architecture account for new building area reaches 30% ", and therefore, assembled is built Building can be greatly developed.But the wall board structure that assembled architecture uses at present is mostly " sandwich sandwich " form, i.e. " 200mm Thick concrete structure wall+50~60mm rock wool heat-preservation layer+60mm thickness concrete cover ", such structural form can play Load-bearing, heat preservation, fire-proof function, falling off also to prevention and treatment insulating layer has certain positive effect, but has the disadvantage that and 1. make work Skill is relatively cumbersome, needs casting concrete in two times using platform prefabricated, and upper layer concrete can only be poured using vibrating head It builds, is easily destroyed insulating layer.2. more traditional " cast-in-place structural wall+external thermal insulation " way obviously has more one layer of 60mm thickness concrete and protects Sheath, cost directly increase.3. after assembling type outer wall plate is installed, the decorative layer (waterproof layer) of usual wall appearance need to be existing Field is completed, rather than factory's integration is completed, and is thereby resulted in site workload and overall construction cost in building course and is increased.

Utility model content

In view of the deficiencies of the prior art, while developing assembled architecture, in order to more effectively realize " four sections, one ring Protect ", green construction value is embodied, therefore propose a kind of collection load-bearing, heat preservation, fire prevention, waterproof, decoration, six Xiang Gongneng of automatically cleaning The one assembly concrete Side fascia of the six directions and its production method being integrated.

A kind of one assembly concrete Side fascia of the six directions, it is characterised in that: dredged including what is be fixedly connected sequentially from outside to inside Water self-cleaning coating layer, flexible board, anticracking grout layer, grid cloth, fire prevention dry-mixed mortar layer, insulation board and concrete slab, in institute State and be evenly distributed with bar for line on insulation board, described bar for line one end end is located in the insulation board, the bar for line it is another One end end is located in the concrete slab, offers the item that several sections are isosceles trapezoid in the lower surface of the insulation board Shape through slot, the bar shaped groove are set side by side and are uniformly distributed, and the upper surface of the concrete slab corresponds to the bar shaped groove Position integrated to be equipped with the fixture block that section is isosceles trapezoid, the fixture block is embedded in the bar shaped groove.

Further are as follows: the insulation board is slapped together by the heat insulating block of several cube types, between every two heat insulating block By being bonded after the isolation of fire prevention parting bead.

Further are as follows: be embedded with bolt collar suspender in the concrete slab side.

Further are as follows: the grid cloth is fiberglass gridding cloth.

Further are as follows: the flexible board is bonded in the anticracking grout layer.

Further are as follows: the concrete slab uses C30 ceramsite foam concrete.

The utility model point of the utility model and the utility model has the advantages that the concrete of each production unit, dry-mixed mortar of preventing fires Multiple enclosure spaces are formed around insulation board with fire prevention parting bead, the enclosure space and outside air completely cut off, and truly have individual When enclosure space is exposed in air by destruction, encountering stronger fire source insulation board may burn, but for not being destroyed Enclosure space is not because have air-breathing, and insulation board will not burn, to reach fireproof purpose；The section is isosceles ladder The bar shaped groove of shape and the bar for line for penetrating setting can increase viscous between insulation board and concrete slab after casting concrete Frictional force is connect, tensile bond intensity meets code requirement；The utility model have load-bearing, heat preservation, fire prevention, waterproof, decoration, from clear Clean effect.
