Abstract

The armouring uses coupled armouring mats (5) for providing a framework enclosing each Bullflex prop (1,3,4), each armouring mat having longitudinal wires and transverse wires. A 3-part construction is assembled from 2 side mats (7,8) and a central mat (6), coupled together along their abutting edges, each mat having hooks for securing to a Bullflex prop, with further Bullflex props attached by hooking further armouring mats to the first Bullflex prop.

Description

The invention relates to a reinforcement for interconnectable Bullflex Pillar according to the features in the preamble of claim 1.

DE 43 04 052 C1 describes a reinforcement mat for external reinforcement of an accompanying dam made of Bullflex pillars for underground. Bullflex pillars consist of a tube made of Bullflex fabric and the outside reinforcements made of reinforcing mats. After installing the outer reinforcement the Bullflex hose is inserted into the reinforcement and at 3 to 4 bar filled early bearing building material. To continuously continue one out To enable Bullflex piers to be built along the line of the DE 43 04 052 C1 proposed two different types of mats combine. Longitudinal mats are required for the first Bullflex pillar are equipped with hairpin-like hooks on both long sides. Between these longitudinal mats extend across mats without hooks. These four mat Ten form a square for the first Bullflex pillar. For all other Bullflex  A third embodiment of a reinforcement mat is required for the pillar is equipped with hairpin-like hooks only on one long side. This Reinforcing mats are hung one behind the other on the long sides Bullflex pillars joined together. The respective cross mats are like therefore carried out without a hook.

The disadvantage of this configuration of external reinforcement is that for everyone Bullflex pillar two different types of mats are required and for the a third type of mat is required for each first Bullflex pillar. ahead It is therefore essential that the right mat types are always used in the the right number are available to open the desired reinforcements to build. However, this is not always the case.

In practice, therefore, it has started to use reinforcement mats those that are only hooked on one long side. Become several Bullflex pillars placed separately next to each other, always four identi cal reinforcement mats used. To attach to a first Bullflex post Connecting the second Bullflex pillar is for the second and each additional one Bullflex pillars require three reinforcement mats each. Now becomes the first Reinforcement mat of the second Bullflex pillar with its hooks in the reinforcement of the first Bullflex pillar and accordingly the second and third reinforcement mat of the second Bullflex pillar to the first reinforcement matte attached, missing for the last connection to the first Bullflex pillar Hook. In order to still be able to connect, the Armie mats connected manually with eyelets or with one-way belts. However, this type of connection is time-consuming and, last but not least, secure technically questionable.  

DE 39 19 841 A1 describes a building material support with transport-friendly Support structure, the support structure consisting of around its longitudinal axis foldable and articulated partial shells in Form of reinforcing mesh exists. The outer longitudinal bars of the part Shells can be hinged together at two or more points be connected, the hinges of wire placed around the longitudinal bars loops are formed. A disadvantage of this preconfigured building material support is that only a single building material pillar can be erected without that a possibility is provided for the individual building material pillars with each other to connect in order to build a dam from building material pillars th.

DE 44 18 937 A1 describes a folding joint mat for the underground Route expansion known. The folding joint mats can be both in anchor  stretch as well as be used in arches and have on their Longitudinal joints to create an articulated connection with the neighbor to produce warp mats. They are drawn in multiple combinations folded like a monika and transported underground. The ends the cross bars or the ends of the longitudinal bars of adjacent mats can be used as Be designed eyelets through which an articulated rod can be inserted can, so that the eyelets form a joint together with the joint rod. Joints can also be formed in that the longitudinal or transverse bars Overall surrounded by a wire spiral on the long and short sides are or separate links in the form of S-shaped wire loops are suspended between the longitudinal and cross bars.

DE 36 12 506 C1 discloses a drafting mat for longwall construction, those of transverse and longitudinal connected at the crossing points wires exists. The cross wires are at least partially at one end bent hook-like and bent in the same direction at the other end angles and connected to each other via a coupling wire. In the dome wire, the hooks of another drafting mat can be hooked in. The newly hung mat can hang down and provides similar protection a curtain the workers in the area of an expansion sign. Now is the end When the construction sign is moved up hydraulically, the freely swinging hanging mat is attached lifted and trapped between the extension plate and the hanging wall. The before The removal sign can be moved until the next mat is back into the coupling wires protruding forward and downwards Mat can be hung. Through side hooks is also an on all mats provided over a face length can be closed together.

Based on this prior art, the object of the invention to create a reinforcement for Bullflex pillars, both for individual standing as well as connected Bullflex pillar is suitable, the is easy to assemble and does not require any additional connecting means.  

The invention solves this problem by the features of claim 1.

Essential in the reinforcement according to the invention for connectable Bullflex pillar is that the reinforcement mats have a three-part structure Zen.

In contrast to the known reinforcement mats for Bullflex pillars, the best hen the reinforcement mats according to the invention from two side mats and a center mat that is articulated on its adjacent longitudinal edges and are captively connected. The three-part reinforcement mat ten form a preconfigured unit and therefore do not have to be on first location to be connected. The assembly effort is thereby significantly reduced.

For coupling a reinforcement mat to another reinforcement mat hook up each reinforcement mat. As a result, a first reinforcement mat in U- shaped arrangement on a single mat hooked to a first Bullflex pillar connectable. Other Bullflex pillars are U-shaped by hooking in more installed reinforcement mats can be connected to the first Bullflex pillar.

Only for the first Bullflex pillar is due to the reinforcement in the form of a Ge Fourth, a single mat is required, which in combination with the U-shaped up position of the reinforcement mats forms a closed reinforcement. It is there if it is possible that the single mat is provided with hooks on its longitudinal edge, so that hookless outer longitudinal edges of the reinforcement mats in the individual mat can be hung. But it is also possible that the outer Longitudinal edges of the reinforcement mats are provided with hooks and these for Setting up a square can be hooked into the single mat. Important is, that each reinforcement mat is provided with hooks over which several ar Mating mats in a U-shaped arrangement can be connected to each other.

There are several for the arrangement of the hooks on the reinforcement mats Possibilities. According to the features of claim 2, it is provided  that the hooks on the longitudinal edges of the sides facing the central mat mats are arranged.

But it is also conceivable that the hook on the facing away from the center mat Longitudinal edges of the side mats are arranged (claim 3). Important is, that either on the outer longitudinal edges of the side mats or in the area the longitudinal edges of the hook facing the center mat are provided according to the features of claim 4 also on the longitudinal edges of the Middle mat can be arranged. The key is that the reinforcement can be erected without additional fasteners.

According to claim 5 it is provided that the mutually facing Longitudinal edges of the middle mat and the side mats over the outer ones Longitudinal wires of the center mat and the side mat at least in sections helically enclosing joint elements are interconnected. The joint elements can extend over the entire length of a longitudinal edge extend. Depending on the length of the longitudinal edge and the expected load it may also be sufficient that the adjacent longitudinal edges of we at least two joint elements arranged at a distance from one another are connected (claim 6). The joint elements exist preferably made of wire, which is helical or helical in a circle the or also elliptical configuration the mutually facing longitudinal wires surrounding the center mat and the adjacent side mat.

The single mat is advantageously provided with hooks on its two longitudinal edges (Claim 7). In this hook of the single mat, the longitudinal edges of the side mats. With this configuration it is expedient that each additional reinforcement mat is designed in the same way as the first reinforcement mat. That is, the outer longitudinal edges of the side mats are designed without hooks, while the facing longitudinal edges the center mat and the side mats are hooked to follow hang in the reinforcing mats.  

In the embodiment according to claim 8, the single mat between two adjacent hooked cross wires at least one Cross wire without a hook, the hooked cross wires can have a larger wire diameter than the cross wires without Hook (claim 9).

The cross wires without hooks are stressed far less than those with Hooked cross wires, so that there is the possibility of a mate rial saving on the cross wires without hooks results without the function the reinforcement is impaired.
