Abstract
The utility model relates to a kind of finished product high-air-tightness wall bushings, including PVC water string, pulika casing, polyurethane foam, gastight adhesive band and waterproof layer, the PVC water string is in outermost and is connected directly with wall, the pulika casing is surveyed in PVC water string, is fixed using polyurethane foam；The waterproof layer is affixed on 90 ° of angles that on wall and PVC water string is formed.The waterproof layer uses high polymer waterproof material.In the utility model, used wall bushing is finished product, pre-buried before masonry panel, floor, directly pours one-pass molding, easy to install and use；Waterproof layer is posted in wall bushing and wall contact position, waterproof trapping protects inner materials to destroy and aoxidize, can ensure that its durability；In the utility model, used wall bushing avoids the appearance of air-tightness loss, enhances building energy conservation performance.
Description
Technical field
The utility model belongs to wall technical field of sealing technology, and in particular to a kind of finished product high-air-tightness wall bushing.
Background technique
With the fast development of China's urbanization and economic society, continuous improvement of people's living standards, cause the energy and
Environment contradiction becomes increasingly conspicuous, and the novel urbanization planning of country proposes specific target to green building ratio.Therefore, passively
The buildings such as room, super low energy consumption are come into being and are rapidly developed.Wall feed-through pipeline on various exterior walls is building external envelope structure door
One of major air breakthrough other than window, building high-air-tightness cause energy waste as the heat preservation and insulation for reducing house
It is the emphasis natural enemy of passive type building with the arch-criminal of loss.Wall bushing as component indispensable in building construction,
How to avoid it from installing brought air-tightness reduces the attention for also gradually causing each side.In conventional construction, applied for cooperation main body
Work progress, often only in wall pre-embedded single tube, the later period reprocesses air-tightness closure before concreting, process flow is multiple
It is miscellaneous, high to quality of materials and the requirement of worker's construction quality, it is careless slightly to be just unable to reach desired effect.It is through walls in passive type building
The air-tightness of casing is dealt with improperly, gently then causes energy loss and passive type effect, heavy then to cause metope mildew ponding to destroy whole
Body thermal insulation property.
Currently, having to wall bushing without the main reason for air-tightness processing: (1) without finished product member, when construction, can not
Disposably it is installed in place；(2) conventional pre-buried common wall pipe post-processing is that air-tightness Joining Technology complexity is careful, construction quality
It is difficult to ensure with effect；(3) it is smaller to account for wall area specific gravity for wall bushing.
Utility model content
It is through walls to better solve the purpose of this utility model is to provide a kind of finished product high-air-tightness wall bushing
The air-tightness of casing blocks processing problem.
To achieve the goals above, the technical solution of the utility model is as follows.
In order to solve the above-mentioned technical problem, the utility model is achieved using following technical scheme:
A kind of finished product high-air-tightness wall bushing, including PVC water string, pulika casing, polyurethane foam, gastight adhesive
Band and waterproof layer, the PVC water string are in outermost and are connected directly with wall, and the pulika casing is in PVC waterproof
It surveys in casing, is fixed using polyurethane foam；The waterproof layer is affixed on 90 ° of angles that on wall and PVC water string is formed.
Further, the waterproof layer uses high polymer waterproof material.
Further, gastight adhesive band is fitted on the inside of waterproof layer.
In the utility model, above structure is installed, electrical and communication class pipeline is directly entered interior by pulika casing,
External pasting air-tightness adhesive tape indoors, and fix and block using heat preserving and insulating material in outdoor, realize high-air-tightness installation and
Connection；Used wall bushing is finished product, pre-buried before masonry panel, floor, directly pours one-pass molding.
The beneficial effect of the utility model is: in the utility model, used wall bushing is finished product, masonry wall
It is pre-buried before body, floor, one-pass molding is directly poured, it is easy to install and use；Waterproof layer is posted in wall bushing and wall contact position,
Waterproof trapping protects inner materials to destroy and aoxidize, and can ensure that its durability；In the utility model, used wall bushing is kept away
Exempt from the appearance of air-tightness loss, enhances building energy conservation performance.
Detailed description of the invention
Fig. 1 is apparatus structure schematic diagram used in the utility model embodiment.
Description of symbols in figure: 1, pulika casing；2, polyurethane foam；3, PVC water string；4, gastight adhesive band；5, prevent
Water layer.
Specific embodiment
Specific embodiment of the present utility model is described with reference to the accompanying drawing, it is practical new to better understand this
Type.
Finished product high-air-tightness wall bushing as shown in Figure 1, including PVC water string 3, pulika casing 1, polyurethane foam
Foam 2, gastight adhesive band 4 and waterproof layer 5, the PVC water string 3 are in outermost and are connected directly with wall, the pulika
Casing 1 is surveyed in PVC water string 3, fixed using polyurethane foam 2；The waterproof layer 5 is affixed on wall and PVC waterproof jacket
90 ° of angles that pipe 3 is formed.The waterproof layer uses high polymer waterproof material.Gastight adhesive band is fitted on the inside of waterproof layer.
In the utility model, above structure is installed, electrical and communication class pipeline is directly entered room by pulika casing 1
It is interior, external pasting gastight adhesive band 4 indoors, and fix and block using heat preserving and insulating material in outdoor, realize high-air-tightness installation
And connection；Used wall bushing is finished product, pre-buried before masonry panel, floor, directly pours one-pass molding.
The above is preferred embodiments of the present invention, it is noted that for the ordinary skill of the art
For personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these are improved and profit
Decorations are also considered as the protection scope of the utility model.
