A hollow access box having an open side is positioned in the form in which the panel is to be poured so that the open side faces the peripheral wall of the form in close proximity thereto. At least one hollow conduit is also positioned in the form and communicates with the interior of the access box. A cap shaped sealing member of resiliently flexible material is securable to the peripheral wall of the frame and extends sealingly into the open side of the hollow access box to prevent intrusion of the liquid concrete into the interior of the access box as well as to maintain the latter in predetermined position relative to the peripheral wall of the form during hardening of the concrete.,下面是Panel form with flexible cap holding access box in sealing relationship专利的具体信息内容。

1. Arrangement for forming a skeleton wiring structure in prefabricated panels made from hardenable material which is introduced in flowable state into a form having a peripheral wall, comprising in combination, at least one hollow access box having an open side and arranged in predetermined position within the form with said open side facing said peripheral wall of the form in close proximity thereto; at least one hollow conduit positioned in the form and communicating with the interior of said access box so that wiring may be inserted into an withdrawn from said conduit through said open side of said access box; and sealing means including a cap member of resiliently flexible material frictionally connected with said access box in sealing relationship therewith, said sealing means also being connectable with the peripheral wall of the form and sealingly and releasably extending into said open side for preventing entry to the interior of said access box of said hardenable material while the same is in flowable state, and for maintaining said access box in predetermined position during the flowable state of said hardenable material.
2. An arrangement as defined in claim 1; and further comprising a sealing bead provided on said cap member for sealing said access box against entry of said material when said cap member extends into said open side of said access box.
3. An arrangement as defined in claim 1; further comprising cooperating sealing ribs respectively provided on said access box and said cap member and sealingly engaging with one another when said cap member extends into said open side of said access box.
4. An arrangement as defined in claim 1, said access box being substantially funnel-shaped and having a converging side opposite said open side, said converging side being provided with an opening communicating with the interior of said access box and for receiving one of said open ends of said coupling member.
5. An arrangement as defined in claim 1; said sealing means further comprising releasable connecting means for releasably connecting said cap member with the peripheral wall of said form.
6. An arrangement as defined in claim 5, wherein said peripheral wall of said form consists at least in part of magnetizable material; said connecting means including a permanent magnet connected with said cap member and arranged for magnetically connecting the same to said peripheral wall of the form.
7. An arrangement as defined in claim 5, said connecting means including a pin member having opposite end portions respectively extending into apertures provided in said cap member and the peripheral wall of the form for maintaining said cap member against lateral displacement relative to the peripheral wall.
8. An arrangement as defined in claim 5, said connecting means including a fastener member extending through said cap member into said peripheral wall of the form.
9. An arrangement as defined in claim 5, said fastener member being a bolt having a weakened zone along which it may be severed during separation of the finished panel and the form.
10. An arrangement for forming a skeleton wiring structure in prefabricated panels made from hardenable material which is introduced in flowable state into a form having a peripheral wall, comprising in combination, at least one hollow access box having an open side and arranged in predetermined position within the form with said open side of said access box facing said peripheral wall of the form in close proximity thereto; at least one hollow conduit positioned in the form and communicating with the interior of said access box so that wiring may be inserted into and withdrawn from said conduit through said open side of said access box; sealing means including a cap member of resiliently flexible material frictionally connected with said access box in sealing relationship therewith, said sealing means also being connectable with the peripheral wall of the form and sealingly and releasably extending into said open side for preventing entry to the interior of said access box of said hardenable material while the same is in flowable state, and for maintaining said access box in predetermined position during the flowable state of said hardenable material; said coupling means for sealingly coupling said conduit and said access box, said coupling means comprising a tubular coupling member of flexible material having opposite open ends respectively communicating with the interior of said access box and said conduit.
