Description
Technical field
The present invention relates to the building block of a kind of type of respiration sandwich wall and utilize the siphonal lobe method for building wall of this building block.
Background technology
The insulation of external wall, generally has Surgery therapy (insulation layer is outside load bearing wall), self-heat conserving (utilizing materials for wall to be incubated, the brick masonry wall as brick mix structure) and inside holding (doing insulation layer inside building) three class.Sandwich wall belongs to the one in Surgery therapy, is to do one deck retaining wall again at the exterior wall of insulation layer, and form the sandwich wall of internal lobe load bearing wall-heat insulating material-siphonal lobe enclosure wall composition, the effect of three layer construction is load-bearing respectively, is incubated and goes along with sb. to guard him.Frame construction etc. be there is no to the structure of outer load bearing wall; need to arrange exterior enclosure wall; now be incubated again outside exterior enclosure wall; and the siphonal lobe enclosure wall of protection insulation layer; then define the sandwich wall of internal lobe enclosure wall-heat insulating material-siphonal lobe enclosure wall, the effect of three layer construction is go along with sb. to guard him, be incubated, go along with sb. to guard him (protection insulation layer) respectively.As a kind of New-type heat insulating walling, sandwich wall utilizes polystyrene board heat-insulatation, and siphonal lobe circummure protects, and can meet the requirement of thermal insulation, also protects insulation layer owing to having solid siphonal lobe wall, makes insulation layer not be subject to destruction, thus have good performance.And the enclosure wall in outside, the splitting block of the ornamental blocks of shades of colour or imitative stone effect can be adopted as required, thus get a promotion on decorative effect, its cost again comparatively lithotome be at half above, therefore have broad application prospects.Increasing in building in recent years.
But in use, due to the crack that siphonal lobe wall may exist, moisture or water can be made to enter into interlayer (insulation layer), and be difficult to timely discharge, long humidity can cause local body of wall mouldy, become mildewed, or the ponding in northern area inside produces freeze thawing, cause body of wall especially siphonal lobe wall cracking.In sandwich wall way abroad, being generally that the duct leading to sandwich of layers is set in siphonal lobe wall, sandwich of layers being made the form that can ventilate, so as to discharging moisture, keeping the drying of sandwich of layers in body of wall.In order to form the sandwich of layers of ventilation, needing the heat insulating material of sandwich of layers to be discontented with and filling out, but reserving the space of about 2cm, utilize space to form the passage of gas.This way has some shortcomings, and one is that heat insulating material needs to be pasted onto on internal lobe wall, and self positions, and adds operation and cost; Two is need additional space, increases the thickness of body of wall, reduces the ratio of usable floor area.Some engineerings, in construction, simplify working procedure, do not paste heat insulating material, save brush coating, but owing to there being space, block benzene plate is often difficult to be kept upright, and keep the state of inclination, define space between each block of benzene plate, reduce heat insulation effect.These problems constrain the application of this body of wall to a certain extent.Therefore the way had no longer stays to establish space, completely filled out by benzene plate, and heat insulation effect promotes, but once enter water in sandwich of layers, be then difficult to discharge, form aforesaid problem.
Summary of the invention
The present invention in order to solve rainwater in existing sandwich wall insulation layer, moisture is difficult to discharge and causes body of wall to become mildewed mouldy problem, and then propose the building block of a kind of type of respiration sandwich wall and utilize the siphonal lobe method for building wall of this building block.
The present invention solves the problems of the technologies described above the technical scheme taked to be:
The building block of a kind of type of respiration sandwich wall comprises building block body, two vertical through holes, two half slots and multiple U-lags, two vertical through holes are symmetricly set on the upper surface of building block body respectively, each vertical through hole is arranged along in the short transverse of building block body respectively, a half slot is respectively equipped with between the front side wall of each vertical through hole and the front end face of building block body, two half slots are symmetricly set on the lower surface of building block body respectively, and the upper surface of building block body is uniform arranges multiple U-lag.
Utilize a siphonal lobe method for building wall for type of respiration sandwich wall building block, described method comprises the steps:
Step one: air inlet through hole is set: first skin mortar joint at the bottom of the upper surface laying of bottom lintel, one group of air inlet through hole is set the front end face of end skin mortar joint is uniform, each air inlet through hole is U-shaped, the upper surface of each air inlet through hole is concordant with the upper surface of end skin mortar joint respectively, and the horizontal range between adjacent two air inlet through holes is 1.2m;
Step 2: masonry panel: build building block body by laying bricks or stones above end skin mortar joint, the multiple U-lags on each building block body are arranged all upward, and two half slots on each building block body are all pressed close to inside body of wall;
Step 3: set out vent hole: lay top skin mortar joint between top layer building block body and top layer lintel, arrange one group and go out vent hole the front end face of top skin mortar joint is uniform, each go out vent hole be inverted U-shaped, each go out the lower surface of vent hole concordant with the lower surface of top skin mortar joint respectively, adjacent two horizontal ranges gone out between vent hole are 1.2m.
The beneficial effect that the present invention compared with prior art comprises is: the invention provides a kind of sandwich wall complete set technology utilizing natural conditions to realize autonomous interchange of air in body of wall, adopt the cavity ensured respiration in special protection building block and building block, achieve siphonal lobe wall to be communicated with the effective of outdoor with insulation layer, the natural air pressure differential utilizing the difference in height of every layer of body of wall top and bottom to produce realizes convection current, reaches the wet object exchanged.Change traditional sandwich wall reserved way being not less than 2cm air blanketing in body of wall, reduce difficulty of construction, ensure that workmanship, enhance in body of wall ventilate, the function of hydrofuge, avoid the heat-insulating property that the sandwich wall insulation layer that freely do not cause because of ventilation dewetting goes mouldy because condensation, steam transmission cause in body of wall, the increase of heat insulating material moisture content causes to decline and the not enough problem of durability.
