Abstract

The utility model relates to a line sandwiched type building sealing strip, belonging to the technical field of accessories of building door and window curtain walls. The sealing strip comprises a sealing strip base body (1), and is characterized by further comprising a fiber line (2) which is embedded inside the sealing strip base body (1) along the length direction. The line sandwiched type building sealing strip is low in transverse extensibility, convenient in assembly, fine in sealing performance and long in service life.

Description

Clamp type building weather strip

(1) technical field

The utility model relates to a kind of building weather strip, particularly relates to a kind of clamp type building weather strip.The door and window curtain wall that is particularly useful for big facade long profiles.Belong to building doors and windows curtain wall auxiliary equipment technical field.

(2) background technology

The building doors and windows weather strip has elasticity (retractility), and vertically the elasticity of (along cross-wise direction) is the reason that it can bring into play sealing function.And weather strip is flexible equally at horizontal (along its length), adhesive tape fast will occur stretching in the process of assembling with section bar (aluminium alloys, plastic-steel or timber window), but this part stretching can not keep lastingly, in use deduct the creep factor, thereby As time goes on weather strip can little by little restore the weather strip physical length is shortened, the result who causes is that the bight of door and window the slit occurs and leaks, and this phenomenon goes wrong when using on the door and window curtain wall of big facade long profiles especially easily.Therefore we wish vertically flexible at weather strip, and smaller even do not have at transversal stretching, but the fact is not like this.Even, can do sizing material hardness softlyer usually in order vertically to have bigger elasticity, but be directly proportional with it, the transversal stretching of weather strip also can be bigger.

If workman's careful work when assembling, speed are slowly, situation can slightly be taken on a new look but be needed strict control, the more important thing is to deal with problems at all particularly also have the factor of weather strip and section bar batch sizes tolerance variations to cause this problem serious attack often.

Can the building doors and windows weather strip be realized long-term seal and realize the assembling steadily fast of weather strip and long profiles, and these two problems all will solve under the prerequisite of the elastic packing performance that does not influence the building doors and windows weather strip.

(3) summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provides that a kind of horizontal extension is little, easy to assembly, the clamp type building weather strip of good seal performance, long service life.

The purpose of this utility model is achieved in that a kind of clamp type building weather strip, and it comprises the weather strip matrix, it is characterized in that it also comprises single, and described single is embedded in weather strip matrix inside along its length.

The utility model clamp type building weather strip because the inhibition of intrinsic fiber line causes the transversal stretching of rubber very little, thereby is realized the quick assembling of building doors and windows weather strip and section bar; And single is very tiny, does not influence the elasticity longitudinally of weather strip, does not promptly influence its sealing performance; Meanwhile owing to be not subjected to drawing stretching action in assembling process, As time goes on weather strip can not shorten yet, and has guaranteed long-term application life.

Compare with existing door and window sealing strip, the utlity model has following characteristics:

1, do not change existing door-window section bar design and assembly technology;

2, add single, cross directional stretch when stoping the weather strip assembling;

3, can improve the efficiency of assembling of weather strip and section bar;

4, long service life has solved owing to weather strip shrinks the difficult problem that the bight cause leaks, and is particularly useful for big facade long profiles situation.

(4) description of drawings

Fig. 1 is the utility model clamp type building weather strip section structure schematic diagram.

Among the figure: weather strip matrix 1, single 2.

(5) specific embodiment

Referring to Fig. 1, the clamp type building weather strip that the utility model relates to is made up of weather strip matrix 1 and single 2, and described single 2 is embedded in weather strip matrix 1 inside along its length.

This practical clamp type building weather strip that relates to, weather strip matrix 1 and single 2 adopt the mode one-shot forming of co-extrusion.

Claims

1. a clamp type is built weather strip, and it comprises weather strip matrix (1), it is characterized in that it also comprises single (2), and described single (2) is embedded in weather strip matrix (1) inside along its length.
