Abstract
The utility model discloses a rubber sealing strip for sealing slab joints of various external wall decorative plates or heat-insulating boards, and various sash joints, which comprises a rubber strip, the main design point of which is providing a flexible metal frame in the rubber strip. The rubber sealing strip is designed in the way that a flexible metal frame is arranged in the rubber strip, thereby when the rubber sealing strip is wedged in slab joints of external wall decorative plates or heat-insulating boards and frame joints of sashes, the rubber sealing strip is tightly inserted in the slab joints and frame joints under the effect of the flexible metal frame, and good sealing is formed. Because of the large tension of the flexible metal frame, the shortage of easy peeling resulting from weakened self-stretch caused by long use time of rubber strip can be covered, and service life of the rubber sealing strip is greatly increased.
Description
Technical field
The utility model relates to construction, seal specifically for building.
Background technology
In building engineering, adopt fluid sealant or sealing joint strip to carry out encapsulation process usually for the plate seam of decorative plate of outer wall or warming plate and the framework slit in the doorframe and window frame.Fluid sealant is generally had relatively high expectations to the cleanliness factor at sealing position, otherwise is very easily come off owing to the colloid self characteristics.Moreover fluid sealant is very easily aging, thereby application life is short, and adopts fluid sealant to be subjected to the influence of weather conditions bigger, as promptly constructing in the rainy day.Employed sealing joint strip in the engineering is generally rubber weather strip at present.Sealing bar sealing effectiveness is poor, and same existence is easily aging, caducous problem.Limited owing to existing rubber weather strip tension force in addition, thereby need make the model that many thicknesses do not wait in process of production, to satisfy the needs of various seal clearances.For solving the problem of rubber weather strip sealing effectiveness difference, CN2749970 discloses a kind of weather strip, and the sealing position of sealing bar is provided with a plurality of projectioies, and this projection can form a plurality of equivalent pressure cavities in position contacted with it when sealing, thereby forms multiple-sealed.The sealing bar has just solved the problem of weather strip sealing effectiveness difference to a certain extent, but waits to solve for other problems.
The utility model content
The purpose of this utility model just provides that a kind of tension force is big, long service life, good sealing effect, and the rubber weather strip of being convenient to install.
The purpose of this utility model is achieved in that
The rubber weather strip that the utility model is designed includes rubber strip, and its design main points are to be provided with the elastic metallic skeleton in rubber strip.
The rubber weather strip of design like this, because rubber strip contains the elastic metallic skeleton, thereby when the framework slit in the plate seam of rubber strip being clamp-oned decorative plate of outer wall or warming plate and the doorframe and window frame, rubber strip is just under the effect of elastic metallic skeleton, tightly embed wherein, formed good sealing thus.Because the tension force of elastic metallic skeleton is big, thus can remedy fully since rubber strip use more long afterwards self elastic force weaken due to caducous defective, the application life of having improved rubber weather strip thus greatly.
Be described in further detail the utility model below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model includes rubber strip 1, is provided with elastic metallic skeleton 3 in the rubber strip 1.Elastic metallic skeleton 3 can be selected steel sheet for use, also can select steel-wire carcass for use.During fabrication, earlier steel sheet or steel-wire carcass are bent into the flat figure with elastic force, snakelike as continuous bending, or the isosceles triangle of continuous bending as shown in fig. 1; The steel sheet or the steel-wire carcass of bending forming are lain in the mould die casting moulding after the rubber mass that is generally used for preparing seal of reinjecting.For the ease of installing and using, the elastic metallic skeleton 3 in the utility model is preferably steel-wire carcass, and this cross-section of its skeleton is curved.Help like this in the weather strip insert plate seam.In order further to strengthen sealing effectiveness of the present utility model, improve its application life, steel-wire carcass is preferably the isosceles triangle of continuous bending, and the both sides of rubber strip preferably are near-spherical 2.The tension force on weather strip both sides equates like this, makes the whole stressed equalization of weather strip, avoids can avoiding producing sealed airspace thus; And the both sides of rubber strip are near-spherical, and the cross section that makes rubber weather strip is just as dumbbell shaped, and in the time of can making rubber weather strip be pressed in plate seam or the frame seam thus, the limit body of two near-sphericals combines, thereby plate that will be darker seam or frame seam are full of, add flat.
The utility model only needs, with special-purpose press strip instrument it to be rolled along the plate seam in weather strip placing plate seam or the frame seam when mounted, sealing joint strip can be embedded the precalculated position.Its sealing function is to rely on self extend out, lining support to carry out fully.Its quick construction, flat appearance, with low cost.
The utility model is applicable to the plate seam of various decorative plate of outer wall of sealing or warming plate, and the frame seam that seals door and windows such as various alumium alloy door and window, plastic-steel door and window.
