Definitions

• the invention relates to a guide device for a pipe laid in a concrete ceiling and in particular for the end of at least one pipe laid in a concrete ceiling having an upper and a lower side.
• a pipe In the production of concrete ceilings with concrete core activation, a pipe is arranged in an approximately middle plane of the concrete ceiling running parallel to the top and bottom, which is held within the reinforcement structure of the concrete ceiling.
• the pipe ends must be led out of the formwork space formed by the formwork.
• Pipe guiding devices for these purposes are e.g. B. from DE-U-85 22 996.2 and CH-A-660 618 known. Since there is an increasing tendency to arrange the necessary distributors from below on the underside of the concrete ceiling for the later installation and subsequent connection of the piping system for the concrete core activation, the pipe ends would have to be led down through the formwork wall. This would have to destroy the formwork wall or provide bushings in the lower formwork wall, which leads to sealing problems.
• a certain disadvantage of the known pipe holder can be seen in the fact that the length of the pipe end section accommodated in the pipe holder is structurally limited and in particular only a small pipe length is available for the arrangement of the distributor in the corner region between the underside of a concrete ceiling and the wall.
• the pipe ends can only be accessed after the bottom formwork wall has been cast, in order to, for example, subject the pipeline laid in the concrete ceiling to a leak test (so-called pressing).
• the invention is based on the object of providing a guide device for at least one pipe laid in a concrete ceiling, which, with the smallest possible dimensions, enables the reception of the longest pipe end section possible.
• the invention proposes a guide device for the end of at least one pipe laid in a concrete ceiling having an upper and a lower side, the guide device being provided with a housing which has an upper side wall, a side wall adjoining this and a has at least partially open underside, with the underside of the housing being able to be positioned essentially at the level of the underside of the concrete ceiling, an opening in the side wall of the housing for inserting the end section of the at least one laid in the concrete ceiling
• Pipe into the housing and at least one protruding pipe bushing protruding from the top wall of the housing for receiving and guiding the pipe end section in the direction of the top of the concrete ceiling.
• the upper side of the housing protrudes from the at least partially open lower side of the housing. lies opposite, a pipe lead-through projection, which is designed in the manner of a pipe guide bend.
• This pipe lead-through projection is directed towards the top of the concrete ceiling, ie away from the bottom of the housing.
• the pipe end section passed through this pipe lead-through projection thus extends in the direction of the top of the concrete ceiling.
• the height of the hollow pipe lead-through protrusion is either adapted to the thickness of the concrete ceiling so that the pipe lead-through protrusion protrudes above the top of the concrete ceiling, or an empty pipe (e.g. corrugated pipe) can be attached to the end of the pipe penetration protrusion facing away from the housing.
• the pipe end section extends through an opening, which expediently seals against the pipe end section, into the housing.
• the pipe end section can be pulled out of the underside of the housing without being destroyed.
• the housing of the guide device according to the invention is expediently elongated and has the opening at one end, while at the opposite end it projects from the top wall of the pipe bushing projection.
• the opening in the side wall towards the underside of the housing is closed off by a pipe routing element which preferably seals against the pipe end section.
• This pipe guiding element can in particular be detachably attached to the housing.
• the pipe guiding element supports the pipe in its area extending through the opening and guides it out of the housing at an angle. This results in a smooth transition between the housing and the pipe laying level within the concrete ceiling.
• the pipe guide device is expediently designed to receive and guide both pipe end sections of the pipe laid in the concrete ceiling. Accordingly, both pipe end sections extend through the opening in the side wall of the housing and then extend further through the housing into a common pipe lead-through projection or up to two separate pipe lead-through projections. It is sufficient if when laying two pipe end sections through the pipe guiding device next to one of the two Pipe end sections is formed an intermediate space for easier detection of the pipe end sections and for pulling these pipe end sections out of the lead-through projections.

• Fig. 3 is a sectional view taken along the line III-III of Fig. 2 to illustrate the underside of the guide device and
• Fig. 4 shows a section through the area of a concrete ceiling without formwork wall, in which the guide device is arranged, wherein the pipes received by it are led out downwards.
• the guide device 10 has a housing 12 with an upper side wall 14 and an adjoining peripheral side wall 16, 18.
• the housing 12 is open towards its underside 20.
• the housing 12 is elongated and has an opening 24 on its side wall 18 forming one end 22 and two pipe lead-through projections 28 at the other end 26, which protrude upward from the top side wall 14 and are hollow.
• the side wall 16 is curved (shown at 30).
• the installation situation of the housing 12 within a concrete ceiling is shown in FIGS. 2 and 4 are shown.
• the housing 12 Before the concrete ceiling 32 is poured, the housing 12 is placed with its open underside on the casing wall 34. Previously, the reinforcement structure 36, 38, 40 was created and a pipe 42 used to activate the concrete core was laid accordingly. The two end sections 44, 46 of the tube 42 are guided through the opening 24 in the side wall 18 of the housing 12. The opening 24 to the casing wall 34 is closed off by a pipe guide element 48 which has an inclined surface for guiding the pipe 42 from the casing wall 34 to the laying plane.
• the two pipe end sections 44, 46 extend through the housing 12 and through the pipe lead-through projections 28.
• the pipe lead-through projections 28 are lower in height than the thickness of the concrete ceiling.
• the height of the pipe lead-through projections it would also be possible for the height of the pipe lead-through projections to be selected such that their ends protrude beyond the top side 50 of the concrete ceiling 32.
• this projection is achieved by fitting empty tubes 52 in the form of corrugated tubes onto the tube lead-through projections 28.
• the pipe end sections 44, 46 led out of the pipe lead-through projections 28 accordingly extend through the empty pipes 52 to over the upper side 50.
• the concrete or mortar 54 of the concrete ceiling 32 now hardens.
• the casing 34 is then removed, so that the situation according to FIG. 4 results after the pipe end sections have been pulled out.
• the intermediate space 54 free space
• the intermediate space 54 not only extends to the side of the pipe end sections 44, 46, but also to the top wall 14 of the housing 12. This is shown in FIG. 1 and in FIGS. 2 and 4 can be seen.
