According to the invention, the tear-out band has a matrix of modified natural rubber which at least partially surrounds the fibres.
Description
Technical field
The present invention relates to a kind of anchor rail that can cast in claim 1 type as described in the preamble.This anchor rail can be cast a member, and described anchor rail consists of to be had: the rail body, and described rail body has the container cavity that extends along the longitudinal extension direction of rail body; Obturator, described obturator are arranged in the container cavity of described rail body; And at least one utilizes the band that tears that fiber strengthens, and the described band that tears is arranged between described rail body and the described obturator, in order to obturator is removed from container cavity.
Background technology
Generally must be sealed in order to avoid concrete enters at the anchor rail of inserting before in the template with concrete curing (Betonieren), thereby do not lost its function.This also can occur by such as PE foam, polystyrene etc. of foam type material is incorporated in the anchor rail.The foam type filler was generally just removed before using the anchor rail again.For example by DE8705644U and US4,532,740A is known with the anchor rail of temporary filler.In addition, by the known a kind of plastic foam filler for the anchor rail of DE29515152U1, it is made by LDPE.
In order to remove easily interim rail filler, for example by US4, the known band that tears of 532,740A, the described band that tears is along on the bottom side that vertically is installed in filler of rail.According to US4,532,740A, described band also can be provided with adhesive and have reinforcing fibre.
Certainly fiber is strengthened tear band and be applied in (einbetonierten) anchor rail that is arranged in the concrete time, what shown is, the described band portion ground that tears is torn just being significantly less than under the load of theoretical tearout, this may cause, and described before throwing off reliably to tear band just inoperative making described filler.
Summary of the invention
The object of the invention is to, a kind of anchor rail is provided, it allows packing material especially simply and reliably to be removed.
According to the present invention, this purpose realizes by the anchor rail with feature claimed in claim 1.Preferred improvement project provides in the dependent claims.
The invention is characterized in that the described band that tears has the matrix of being made by the natural rubber after the modification, described matrix surrounds described fiber at least in part.
Test made us showing with feeling surprised, the Partial Observation that tears band that known fiber is strengthened to inefficacy (Versagen) be not to lose efficacy owing to fiber itself usually, but the matrix inefficacy of imbedding owing to described fiber.Described matrix has following shearing resistance under int state, what it can be realized is to make load be distributed on the described fiber and therefore make as far as possible all fibres all participate in loading and transmit.If present described matrix is malfunctioning, load is not redistributed on all fibres so, but only is on a small amount of several fiber.So these fibers rupture in advance, the result who brings is, load only is on a small amount of fiber again once more, and these fibers rupture again, etc.In weakened matrix, bear unevenly the therefore gradually fracture of fiber of load, until whole band is all torn.
Test makes us also showing that owing to the mixed earth of liquid state, described liquid concrete for example can corrode described matrix owing to its high namely alkaline pH value usually in the weakening of observing of matrix with feeling surprised.Yet, install on the template so that the separating mechanism of the mixed adhesion of concrete on form surfacing of reduction also may have a negative impact to described matrix.
At this, it should be noted that described tear band not only may the outstanding brace of anchor rail and distolateral on and also may follow closely the adverse effect that concrete liquid is born in the hole at it.What shown in test is, diameter only is that perhaps 3 millimeters nail hole just can produce the lasting infringement to described band, and the result who brings is that described band is just in time torn at the position in nail hole and no longer can be provided the functional of described band.It should be noted that also at packing material not seal fully in the situation of inner chamber of described rail that mixed earth liquid may enter via distolateral, can be in the bottom of anchor rail fully by mixed earth liquid dip-dye thereby tear band.This may be so that described band be fully unavailable.
The present invention is based on following understanding of making us feeling surprised, i.e. described malfunctioning malfunctioning owing to described matrix that tears band, and described matrix this malfunctioning may be again based on the adverse effect of mixed earth itself.The present invention proposes, and the natural rubber after the modification is used as matrix material.Made us in the test showing that natural rubber is because the alkaline corrosion of mixed earth can cause at most the limit impaired with feeling surprised.
This discovery be, natural rubber is special resistance to chemical attack not only, and it can be used for tearing band in the advantageous mode of tool simultaneously and stick to obturator, described obturator preferably has foamed material.By such adhesion, can avoid described band below obturator in the very short situation lower slider of rail spare, and do not need the adhesive layer that adds.Therefore, particularly preferably be, the described matrix of being with the natural rubber after it is by modification to make that tears sticks on the described obturator.Advantageously, described matrix directly abuts on the obturator, that is to say not have for example adhesive layer of layer between matrix and obturator.
Advantageously, the described band that tears has carrying belt, is furnished with described matrix and/or described fiber at described carrying belt.Described carrying belt especially can have polyethylene (PE), polypropylene (PP) or PETG (PET).
Preferably, described fiber is glass fiber.Described fiber is not only with respect to the natural rubber matrix but also with respect to all special resistances to chemical attack of mixed earth liquid according to the present invention.Especially, can be with long filament as fiber.Described fiber is advantageously along vertical distribution of tearing band.
In addition, what conform with purpose is, described obturator has the exruded foams material, and described exruded foams material has the epidermis of extruding at least in the described zone that tears band.This epidermis of extruding has guaranteed that the described band that tears is attached on the obturator especially well.Simultaneously, the described epidermis of extruding can stop mixed earth liquid to enter in the obturator in the mode of not expecting, perhaps this can make pulls out described obturator difficult.
Especially in order to resist the diffusion of concrete liquid in filling, also may tool be advantageous be that described obturator has the exruded foams material of closed pore.
For example consider that manufacturing cost can set, described obturator has low density polyethylene (LDPE) (LDPE).In this case, it should be noted that LDPE is not special tension, thereby the band that tears that utilization is weakened usually can not removing with traction realization LDPE obturator.But under tearing with impaired situation, usually producing many single foam blocks, it also must individually be removed again.Therefore, according to the present invention ground use the natural rubber matrix just with the combination of LDPE obturator under have especially advantage, the weakening that band is torn in described natural rubber matrix antagonism.Experiment shows, described rail is pegged and nail not only passed described tear band but also pass described obturator in, this combination can realize taking out foam.
In addition, experiment shows, removing when for example appearing at embedding and getting concrete epidermis (Betonkruste) in the somewhat dark a little anchor rail or sustain beaing of hammer when seeking described starting point of tearing band with the band that tears of natural rubber matrix.In the described combination of materials, the described band that tears can form the tension unit with obturator in front, its acting in conjunction and can realize the simple taking-up of obturator when removing obturator.
Further improvement to the stability of tearing band can realize by following scheme: keep apart in order to make glass fiber and external corrosion environment, can production tear with the time two bands being made by natural rubber are set, between them, be furnished with a glass layer sandwich-type.Then, can make each described natural rubber roll coil of strip together and connect by adhesive or by heat effect, thereby they surround described glass layer in both sides.
