Abstract
Abstract The present sealing device for expansion gaps between adjacent structural members is connected to the side walls forming the gap by poured, hardening synthetic resin concrete. The sealing strip proper is anchored in lost casing means embedded at least partially in said synthetic resin concrete. The lost casing means are formed so that the sealing strip proper may act as an anchor for a removable form body or core which is used to give the poured synthetic resin concrete the shape in which it is supposed to harden. Once the resin is hardened, the form body may be removed. Preferably, the sealing strip has an M-sectional shape or an inverted V-sectional shape whereby preferably the free ends are anchored to the lost casing and the tips are anchored to the form body.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
138 words
An expansion gap sealing device for sealing an expansion gap comprising an elastic sealing strip adapted to be anchored by means of synthetic resin concrete, said sealing strip comprising first anchoring means for securing a form body to said elastic sealing strip, said first anchoring means including a contoured top surface having shoulder means at the edges thereof on said elastic sealing strip to provide a supporting area for said form body, said supporting area providing for an intimate contact between the sealing strip and said form body substantially over said entire top surface of said elastic sealing strip, and seconD anchoring means for anchoring said sealing strip in the expansion gap, whereby said first and second anchoring means and said supporting area combine for rigidly supporting said form body during the setting of said synthetic resin concrete.
Claim 2
Dependent Claim
138 words
An expansion gap sealing device for sealing an expansion gap comprising an elastic sealing strip adapted to be anchored by means of synthetic resin concrete, said sealing strip comprising first anchoring means for securing a form body to said elastic sealing strip, said first anchoring means including a contoured top surface having shoulder means at the edges thereof on said elastic sealing strip to provide a supporting area for said form body, said supporting area providing for an intimate contact between the sealing strip and said form body substantially over said entire top surface of said elastic sealing strip, and seconD anchoring means for anchoring said sealing strip in the expansion gap, whereby said first and second anchoring means and said supporting area combine for rigidly supporting said form body during the setting of said synthetic resin concrete.
Claim 3
Dependent Claim
25 words

Claim 4
Dependent Claim
40 words
The sealing device according to claim 1, comprising a plurality of wall sections extending longitudinally of said strip, two each of said wall sections merging into each other to form anchoring ridge means as part of said contoured top surface.
Claim 5
Dependent Claim
23 words
The sealing device according to claim 3, wherein two adjacent wall sections merging into said anchoring ridge means form an inverted V-sectional shape.
Claim 6
Dependent Claim
28 words
The sealing device according to claim 3, wherein said wall sections form an M-sectional shape whereby the two tips of said M-sectional shape comprise said anchoring ridge means.
Claim 7
Dependent Claim
15 words
The sealing device according to claim 1, wherein said second anchoring means comprise bulging edges.
Claim 8
Dependent Claim
13 words
The sealing device according to claim 6, wherein said bulging edges are hollow.
Claim 9
Dependent Claim
16 words
The sealing device according to claim 1, wherein said first anchoring means comprise longitudinal hollow ridges.
Claim 10
Dependent Claim
14 words
The sealing device according to claim 8, wherein said hollow ridges are open downwardly.
Claim 11
Dependent Claim
21 words
The sealing device according to claim 1 wherein said shoulder means is located adjacent to and above said second anchoring means.
Claim 12
Dependent Claim
95 words
The expansion gap sealing device of claim 1, comprising a form body having a bottom surface with third anchoring means therein, said first and third anchoring means cooperating with each other for directly securing said form body to said sealing strip, said third anchoring means comprising recess means in said bottom surface of said form body, said first anchoring means comprising snap-in means which fit into said recess means in a form locking manner, said recess means comprising recess defining walls, and an entrance opening of given width and an inner diameter of greater width.
Claim 13
Dependent Claim
96 words
The expansion gap sealing device of claim 11, wherein said bottom surface of said form body has acute angled wall sections positioned to merge into said recess means at the entrance opening thereof, said acute angled wall sections of said bottom surface having a given surface area, said top surface of said sealing strip having a contoured area corresponding substantially in surface area to said given surface area and being shaped to closely fit the acute angled wall sections of said form body, whereby said form body is held in hugging contact on said sealing strip.
Claim 14
Dependent Claim
25 words
The expansion gap sealing device of claim 11, wherein said form body comprises means positioned to rest on said shoulder means of said sealing strip.
Claim 15
Dependent Claim
53 words
The expansion gap sealing device of claim 1, further comprising casing means for anchoring said sealing strip to gap forming walls in concrete members by means of said synthetic resin concrete, said casing means comprising lost casing sections, said lost casing sections being anchored to said second anchoring means of said sealing strip.
Claim 16
Dependent Claim
100 words
The expansion gap sealing device of claim 14, wherein said second anchoring means comprise contoured edged portions on said edges of said sealing strip, said lost casing sections comprising channel means having an open side and a wall portion inclined toward said open side, said contoured edged portions of said sealing strip being fitted into said channel means in a form locking manner with the inclined wall portions of said casing sections holding the contoured edged portions of the sealing strip inside said channel means, said shoulder means of said sealing strip being above and outside of said channel means.
Claim 17
Dependent Claim
