Definitions
- the invention relates to an expansion profile for mining and tunneling, consisting of two I-profiles, the butted inner flanges of which are connected to form a box profile.
- expansion profiles which can fulfill the function of caps and beams.
- This preferably includes web profiles such as I-profiles, channel profiles and box profiles, although channel profiles are regularly used as route arches.
- the expansion profiles must either be supported by stamps or, using rock anchors, be hung from the hangers under the expansion profiles.
- the connection of the expansion profiles is generally carried out by means of overlapping and external tabs.
- the stamps to be placed, as well as the tabs to be mounted, are disruptive for various reasons. In addition to the cost of materials, the stamps hinder, for example, when setting up and taking down.
- the invention has for its object to provide an expansion profile for the pit and tunnel expansion of the type described above, which can be installed without support, enables the end connection of other expansion profiles without outer straps and can therefore be used as a track.
- a box profile is realized as an expansion profile, which can be secured by means of rock anchors, e.g. B. expansion sleeve anchor, cement mortar anchor or adhesive anchor, can be properly attached to the mountains and especially on slopes.
- rock anchors e.g. B. expansion sleeve anchor, cement mortar anchor or adhesive anchor
- a support-free or stamp-free installation of the expansion profile according to the invention is consequently possible, both in the stretching and longitudinal direction as well as in the transverse direction.
- an outer lug-free connection with an adjacent expansion profile in the area of the butt ends is made possible because the An Have closing means placed on the one hand in the cavities of the box profiles to be connected, and on the other hand have them locked into place by inserting them into the cavities.
- the expansion profile according to the invention is stamp-free or support-free, there is now sufficient space for the undisturbed installation of conveying and extraction facilities in the manufacture of thawing and dismantling as well as in the setting up of machine stalls, while the setting and robbery of the construction of line accompanying dams There is no stamping.
- expansion profiles according to the invention can be arranged one above the other and recesses can be locked in the area of the assembly, irrespective of whether they are intersecting expansion profiles or rectified expansion profiles. It is also possible to use suspension devices in the lower mounting recesses of the centrally anchored expansion profile. Finally, the connection to route expansion profiles and especially route arches - preferably in the transition area from the strut to the route - is no problem. Flawless securing of the expansion spaces is always ensured by stamp-free or support-free installation of the expansion profile according to the invention as a cap or beam using rock anchors.
- the invention provides that the inner flanges of the upper and lower I-flange narrower than the outer flanges, for. B. are half as wide. This allows an expansion profile to be realized which is relatively narrow, even though it is a box profile. Besides, that can expansion profile according to the invention can also be used in a conventional manner as a cap or underside, ie with the support of a stamp, if this should be absolutely necessary. However, a suspension using rock anchors is preferably provided. For this reason, the invention teaches that the upper and lower mounting recesses are aligned as congruent recesses, which facilitates the passage of the anchor rods through the mounting recesses. The expansion profile is secured using an anchor plate and.
- the mounting recesses are preferably designed as elongated holes and symmetrical in vertical projection, between the I-webs. arranged for the purpose of central anchoring.
- the elongated holes ensure the necessary play for the passage of the anchor rods of the anchors that have already been placed in the course of installing the expansion profile.
- the distance between the mounting recesses can be twice as long as their length. - Mach a preferred embodiment of the invention with independent meaning is provided that the Aufienfl near the I-flange see are designed as running surfaces for load drives, that the expansion profile according to the invention thus fulfills the function of a running rail.
- expansion profile according to the invention can be connected to other expansion profiles in the region of its butt ends without the use of external brackets, that is to say it can be assembled into an uninterrupted running rail without disruptive connecting elements.
- This also results in the possibility of moving a drilling device with an anchor setting device on the expansion profile according to the invention or the resulting running rail, which thereby always is in place for setting mountains anchors are available.
- dam construction elements e.g. B. to erect a blower offset wall or similar devices on the continuously laid running rail by means of the load drives, so that the expansion profile according to the invention can also be used for track driving.
- the outer longitudinal edges of the outer flanges are provided with recesses at predetermined intervals to form cams, in which the crown-like stamp heads can engage in a manner known per se.
- the invention teaches that coupling pieces which can be angled about horizontal and / or vertical axes can be inserted at the end into the box section of the expansion profile according to the invention and can be locked in the area of the mounting recesses and angled gearbox.
- the expansion profile according to the invention can also be used as a rigidly connectable and attachable joint cap.
- an expansion profile for pit and tunnel expansion is realized, which can be installed without support, that is to say without stamps, outer straps or the like.
- This support-free installation is achieved by means of rock anchors, so that the expansion profile according to the invention is practically suspended from the slope.
- installation on the bed is also possible.
- the support-free and yet safe installation of the expansion profile according to the invention as a cap or beam results in freedom of space or freedom of movement when creating and setting up hewing and dismantling as well as in Transition area from longwall to route or. Machine stall. It is also possible to create stamp-free route accompanying dams.
- the expansion profile according to the invention ensures an external link-free connection with expansion profiles to be connected at the end, so that a continuous running rail for load drives and consequently equipment and load transport is available. - This succeeds with relatively simple and functional means.
- FIG. 2 is a plan view of the object of FIG. 1,
- FIG. 3 shows a partial longitudinal section through the object according to FIG. 1 in the area of mounting recesses with an inserted suspension
- Fig. 4 is a partial longitudinal section through two coupled expansion profiles with the interposition of a coupling piece with a lockable joint and
- FIG. 5 is a top view of the object of FIG. 4.
- an expansion profile 1 for the pit and Tunnel construction shown which in its basic structure consists of two I-profiles, the butted inner flanges 2 connected to each other to form a box profile, namely welded.
- the box profile has 4 mounting recesses 5 in its upper I-flange 3 and in its lower I-flange.
- the mounting receptacles 5 are arranged at predetermined intervals on the central longitudinal axis M of the I-flanges 3, 4.
- the upper and lower mounting recesses 5 overlap in a vertical projection.
- the mounting recesses 5 are preferably aligned as congruent recesses.
- the inner flange 2 of the upper and lower I-flange 3, 4 are narrower than the outer flanges 6, z. B. half as wide, that the I-profiles are asymmetrical
- the mounting recesses 5 are designed as elongated holes and arranged symmetrically in a vertical projection between the I-webs 7.
- the distance A of the mounting recesses 5 is twice as long as their length L according to the exemplary embodiment.
- the outer flanges 6 of the I-flange 3, 4 are designed as running surfaces for load drives, so that expansion profiles 1 according to the invention can be assembled without the use of ash outside to form a running rail, the mounting recesses 5 enable the support-free connection to the rock anchor.
- the outer longitudinal edges of the outer flanges 6 can have recesses 9 at predetermined intervals in a known manner, with the formation of cams.
- coupling pieces 11 which can be angled about horizontal and / or vertical axes 10 can be inserted into the box profile or to be connected to one another, which can be locked in the area of the mounting recesses 5 and their angled joints 12, for example by means of wedges 13, 14.
