Abstract
The invention relates to a novel line-clamping building seal strip. The seal strip comprises a left arc section (1), a right arc section (2), a horizontal section (4) and a fiber wire (6), wherein the upper end of the right arc section (2) stretches out from a connecting point to form an extending section (3); a supporting leg (5) is disposed on the left end of the horizontal section (4); the fiber wire (6) is embedded in the horizontal section (4) along the length direction; a hollow structure (7) is formed through enclosing of the left arc section (1), the right arc section (2) and the horizontal section (4); multiple concave troughs (8) are formed in the inner wall of the hollow structure (7); a a comb-shaped insertion body (9) made of resin is inlaid in the seal strip; and the insertion body (9) comprises a body (9.1) and a tooth part (9.2). The novel line-clamping building seal strip provided by the invention has the advantages that horizontal flexibility is low; assembly is convenient; sealing performance is good; the service life is long; the seal part has high grasping force to a matched part; and the seal strip has high flexibility in bending operations.
Description
Technical field
The present invention relates to a kind of building sealing strip, more particularly to a kind of new line sandwiched type building sealing strip, for the door and window curtain wall of big facade long profiles.Belong to building doors and windows curtain wall auxiliary equipment technical field.
Background technology
Building doors and windows sealing strip has elasticity（Retractility）, longitudinal direction（Along cross-wise direction）Elasticity be the reason for it can play sealing function.And sealing strip is horizontal（Along its length）Same have elasticity, adhesive tape with section bar（Aluminium alloy, plastic-steel or Wood-door window）Stretching just occurs during quick assembling, but this part stretching persistently can not keep, creep factor is deducted in use, As time goes on sealing strip little by little can restore, so that sealing strip physical length shortens, caused result is that door and window corner gap occurs and leak, and this phenomenon is particularly susceptible when using on the door and window curtain wall of big facade long profiles and goes wrong.Therefore it is desirable that flexible in the longitudinal direction of sealing strip, and it is smaller even without but the fact is not so in transversal stretching.In order to longitudinal direction have bigger elasticity, it will usually sizing material hardness do it is softer, but therewith into this than, the transversal stretching of sealing strip also can be bigger；Existing sealing strip is made using gum material, therefore little to the grip of counterpart, flexible poor during bending operation, it is impossible to meet the demand of client.
The content of the invention
It is an object of the invention to overcome above-mentioned deficiency, there is provided one kind fills new line sandwiched type building sealing strip.Its transversal stretching is little, easy to assembly, good airproof performance and long service life, while this sealing member is big to the grip of counterpart, has good flexibility during bending operation.
The object of the present invention is achieved like this：
A kind of new line sandwiched type building sealing strip, is characterized in：The new line sandwiched type building sealing strip includes left segmental arc, right segmental arc, crosspiece and single, the upper end of the left segmental arc is connected with the top of right segmental arc, stretch out junction point in the upper end of right segmental arc, form extension, the lower end of the lower end of the left segmental arc and right segmental arc is connected with the right part of crosspiece, the left end of crosspiece is provided with leg, the single is embedded in crosspiece along its length, single adopts co-extrusion mode one-shot forming with sealing strip, the left segmental arc, right segmental arc and crosspiece surround a hollow structure, multiple grooves are provided with the inwall of the hollow structure, the sealing strip is embedded in the insertion body for adopting the pectination being made of resin, the insertion body includes body and is arranged on the teeth portion on body both sides.
Compared with prior art, the invention has the beneficial effects as follows：
A kind of new line sandwiched type building sealing strip of the present invention, left segmental arc, right segmental arc and crosspiece surround a hollow structure, not only reduce the consumption of sealing strip, while so that the compression ratio of sealing strip is greatly improved；Multiple grooves are provided with hollow structure inwall, when sealing strip is compressed, groove can enter row buffering, prevent the inwall of hollow structure from damaging；Single is embedded in crosspiece along its length, as the inhibition of intrinsic fiber line causes the transversal stretching very little of sealing strip；The left end of crosspiece is provided with leg, and leg can help staff to be positioned when installing；Sealing strip is embedded in an insertion body for adopting the dressing being made of resin, therefore can improve grip of the sealing strip to counterpart, while sealing strip has good flexibility during bending operation.

Specific embodiment
Referring to Fig. 1-2, a kind of new line sandwiched type building sealing strip of the present invention, including left segmental arc 1, right segmental arc 2, crosspiece 4 and single 6, the upper end of the left segmental arc 1 is connected with the top of right segmental arc 2, stretch out junction point in the upper end of right segmental arc 2, form extension 3, the lower end of the lower end of the left segmental arc 1 and right segmental arc 2 is connected with the right part of crosspiece 4, the left end of crosspiece 4 is provided with leg 5, the single 6 is embedded in crosspiece 4 along its length, single 6 adopts co-extrusion mode one-shot forming with sealing strip, the left segmental arc 1, right segmental arc 2 and crosspiece surround a hollow structure 7, multiple grooves 8 are provided with the inwall of the hollow structure 7.
The sealing strip is embedded in the insertion body 9 for adopting the pectination being made of resin, and the insertion body 9 includes body 9.1 and is arranged on the teeth portion 9.2 on 9.1 both sides of body.
Operation principle：The left segmental arc 1, right segmental arc 2 and crosspiece surround a hollow structure 7, not only reduce the consumption of sealing strip, while so that the compression ratio of sealing strip is greatly improved；Multiple grooves 8 are provided with 7 inwall of hollow structure, when sealing strip is compressed, groove 8 can enter row buffering, prevent the inwall of hollow structure 7 from damaging；Single 6 is embedded in crosspiece 4 along its length, as the inhibition of intrinsic fiber line causes the transversal stretching very little of sealing strip；The left end of crosspiece 4 is provided with leg 5, and leg 5 can help staff to be positioned when installing.
