Definitions
- connection component having a formwork interface for detachable connection to a frame of a formwork panel.
- the invention also relates to a system for shuttering a wall element, comprising at least one shuttering panel and at least one connecting component.
- the invention relates to the field of construction.
- building parts are often formed by pouring concrete.
- the shape of these cast building parts is specified by a formwork, the formwork being erected on the construction site before the casting.
- ceilings or walls of a building are erected with the help of formwork.
- scaffolding is required in order to be able to prepare the formwork for the construction of the wall element.
- scaffolding is required to connect individual formwork panels to form the overall formwork, for example by attaching formwork locks.
- two opposing formwork panels must be connected to one another by means of anchors in order to absorb the outward pressure of the poured concrete material.
- the formwork panels must be accessible to workers over their entire height, which is usually done using scaffolding or a working platform.
- reinforcement In most cases, before the wall element is produced, reinforcement must be attached to an already positioned formwork or between such a formwork and a closing formwork which is opposite the formwork.
- scaffolding or working platforms that are provided for attaching formwork locks are arranged on the formwork in such a way that no reinforcement can be attached to these scaffolding or working platforms.
- the places where the reinforcement must be positioned are simply not accessible from these scaffolding or work platforms used to prepare the formwork panels, since they are on the opposite side of the formwork panel. In practice, this means that a first type of scaffolding is required to operate the formwork and a second type of scaffolding is required to position and insert the reinforcement into the formwork.
- the object of the present invention is therefore to simplify the production of a wall element, in particular to enable flexible, universal and/or secure attachment of scaffolding, platforms and/or supports to formwork panels.
- a connection component having a formwork interface for detachable connection to a frame of a formwork panel, the formwork interface comprising a first gripping device having at least one first gripping arm with a clamping jaw and a second gripping device having at least one second gripping arm with a clamping jaw, the first gripping arms of the first gripping device can be moved in a closing direction relative to the second gripping arms of the second gripping device in order to connect or release the clamping jaws to the frame and having at least one attachment interface for detachable connection to an attachment, the formwork interface and the attachment interface being operable independently of one another .
- connection component creates a combination between a formwork interface and an attachment interface, with which a large number of different objects, in particular different types of scaffolding, platforms, supports, etc., can be detachably connected to the frame of the control panel in an advantageous manner.
- the attachment interface can in particular be connectable as an attachment to a scaffolding section, in particular a vertical post of a scaffolding, a platform section, a support, in particular an alignment support.
- several add-on part interfaces can also be provided, in particular an add-on part interface for a scaffolding section and an add-on part interface designed separately therefrom for a support, in particular an alignment support.
- the attachment interface can preferably have a connection clamp for receiving an attachment.
- the connecting clamp can preferably be non-positively connected or connectable to, for example, a vertical post of a scaffolding section.
- the formwork panel to which the connecting component can be releasably fixed can preferably have a frame on the front side of which a formwork skin can be fixed, in particular attached or attached.
- the frame of the formwork panel also preferably has a plurality of longitudinal struts and a plurality of transverse struts running plane-parallel to one another.
- the longitudinal struts and the transverse struts can be arranged essentially perpendicularly to one another or can run perpendicularly to one another.
- At least one arc-shaped bridging element can be arranged between at least two transverse struts running adjacent to one another.
- the bridging element can have two end areas, one of the end areas being fixed to one of the two adjacent crossbars.
- the arched bridging element can simplify the handling of the formwork panel in an ergonomically advantageous manner. With the help of the curved bridging element, the formwork panel can be transported and positioned more easily. Insofar as this is legally permissible in the respective jurisdictions, the bridging element can advantageously also serve as a handle and/or as a climbing aid or as a climbing strut, in particular in connection with scaffolding positioned adjacent to or on the formwork panel.
- the arched bridging element can in particular be an arched handle.
- the arcuate design of the bridging element makes it possible in a particularly advantageous manner for a worker to be able to grip around the bridging element.
- the shuttering interface may include a locking mechanism to adjust and/or releasably fix the position of the gripping arms in the closing direction.
- the locking mechanism allows the clamping jaws of the first and second gripping arms to be connected, e.g. clamped, to the frame, in particular to the transverse struts and/or the longitudinal struts of the frame.
- the locking mechanism can include a wedge, the outer contour of which preferably at least partially forms a control surface.
- This measure provides a simple, detachable and at the same time secure locking option.
- the two gripping devices can each have recesses which at least partially overlap one another and into which the wedge can be inserted or has been inserted.
- the connecting component is designed in such a way that a movement of the wedge relative to the recesses leads to a closing movement (in the closing direction), in which the gripping arms move towards one another relative to one another.
- one of the gripping devices preferably the first gripping device
- the closing movement of the gripping devices results only from the movement of one of the two gripping devices, preferably the second gripping device, which thus also moves relative to the frame, eg orthogonally to a crossbar of the frame to which the connecting component is to be fixed.
- the wedge can be arranged captively in the recesses, with the wedge preferably having stops projecting beyond the recesses at its front ends in order to form the captive device.
- the captive device can be designed, for example, in the form of a dowel pin, a dowel sleeve, a cotter pin, a securing pin, a bolt or the like.
- the control surface of the wedge can preferably be designed in such a way that by moving the wedge into a locking position, the gripping arms of the first gripping device and the second gripping device move relative to one another in the closing direction and these are thus attached to the frame, in particular to transverse struts and/or longitudinal struts of the frame , attack or engage in the frame or be clamped to the frame.
- control surface of the wedge or the locking mechanism is particularly suitable if, as will be explained in more detail below, the frame, in particular the transverse struts and/or longitudinal struts of the frame, have grooves and the clamping jaws of the gripping arms engage in the grooves.
- the wedge can be brought into its locking position with a hammer or a similar suitable tool.
- the first gripping device can preferably have two first gripping arms and the second gripping device can have a second gripping arm.
- the gripping arms can run plane-parallel and at a distance from one another, and the second gripping arm can be arranged in an intermediate space, preferably centrally, between the two first gripping arms.
- At least one bolt can be present, which bridges a gap between the first gripping arms and is arranged in such a way that it serves as a stop for movement of the second gripping arm against the closing movement.
- the bolt can also be provided to connect the two first gripping arms to one another. It is advantageous if the clamping jaws have a projection at their front ends which is designed to engage in grooves in the frame.
- transverse struts and/or the longitudinal struts has at least one groove in the upper side and the lower side, which runs in the longitudinal direction of the transverse struts.
- the “top” and the “bottom” of the transverse struts are also collectively referred to as side surfaces.
- the profile of the transverse struts and/or the longitudinal struts can preferably have the shape of a bone or an "H".
- different scaffolding, platforms and/or supports in particular push-pull supports, can be attached to the formwork panel in a particularly simple and secure manner.
- the connecting component whose gripping devices or gripping arms are preferably adapted to the profile, can be variably attached to the frame and removed again. Scaffolding, platforms and/or supports, in particular props, can thus be attached particularly flexibly for aligning the formwork.
- connection components can be fixed to the frame in a particularly advantageous and flexible manner.
- the grooves can be arranged axially symmetrically to one another and/or arranged opposite one another and, viewed in cross section, have at least approximately the same shape.
- a stable non-positive and positive connection can be created between the connecting component and the longitudinal struts and/or transverse struts of the frame of the formwork panel.
- the clamping jaws are preferably designed to be complementary in shape to the grooves in the longitudinal and transverse struts of the formwork panel.
- the relative position between the connecting component and the formwork panel can be designed to be steplessly adjustable in a direction parallel to the direction in which the grooves run in the longitudinal struts and/or transverse struts.
- the connecting component can be used particularly advantageously since the connecting component can be attached to the frame in a suitable horizontal (or also vertical) position, in particular with the aid of the grooves, in particular along the cross braces of the frame.
- the position between the formwork interface and the attachment interface can also be adjustable.
- a connecting part formed on the attachment interface for example a connecting clamp of the attachment interface, can be designed to be infinitely adjustable in its position relative to a scaffolding section, for example a vertical post. The connecting component thus enables the position between the formwork panel and the scaffolding section or an alignment support to be adjusted in two spatial directions oriented perpendicularly to one another.
- connection component can be fixed in a captive manner on the longitudinal and/or transverse struts of the frame of the formwork panel.
- the grooves in the upper and lower sides of the respective transverse struts and/or longitudinal struts run eccentrically, such that the grooves run closer to a rear side of the frame than to the front side.
- the grooves in the upper side and the lower side preferably run at a constant or even distance from the edges of the upper side or the lower side of the transverse strut or the longitudinal strut.
- the grooves preferably run off-centre in the top or bottom of the transverse struts and/or longitudinal struts in such a way that the grooves are at a greater distance from a front edge of the strut, in which the top or bottom touches the front of the frame or the formlining abuts than to the respective rear edge of the strut that abuts the rear of the frame. Due to the fact that the grooves run eccentrically in this way, the connection component can be fixed or clamped particularly advantageously in the grooves.
- cross braces have holes in the upper side and/or the lower side that are spaced apart from the grooves and are preferably used for draining liquids, for example rainwater.
- the side walls or flanks of the respective grooves are inclined outwards from a groove base of the respective grooves, the side walls preferably being able to enclose an angle of 95° to 125°, in particular 110°, with the groove base.
- the grooves can preferably have a depth of 9 mm to 16 mm, preferably 13 mm.
- connection component The aforementioned values have turned out to be particularly suitable for determining the connection component.
- This geometry allows the connecting components to be fixed in the grooves in a particularly simple and non-twisting manner, preferably by clamping.
- one or more bridging elements has proven to be particularly advantageous in connection with cross struts that have at least one groove in the top and bottom, which run in the longitudinal direction of the cross struts, in particular as above described.
- the curved course of the bridging element is particularly suitable. Due to the curved shape of the bridging element, it is possible to fix the bridging element in a section of the upper side or the lower side of the cross braces that does not have a groove. These sections are adjacent to the front of the frame.
- a configuration of the bridging element with a linear progression would have the disadvantage that a worker's hand cannot suitably or easily grasp the bridging element due to the spatial proximity to the front side of the frame and thus also to the formwork skin. This problem is advantageously solved by the arcuate design of the bridging element.
- the frame has two outer frame cross braces and two outer frame longitudinal braces, between which inner cross braces are arranged.
- all inner cross braces have the grooves and the outer frame cross braces have no grooves. It has been found to be sufficient if all inner cross members have grooves. The additional formation of grooves on the outer frame cross braces can therefore also be omitted for cost reasons.
- the formwork interface and at least one of the attachment interfaces can be releasably connected to one another, the formwork interface and the attachment interface preferably each having a contact surface with an elongated hole, and a fastening element being insertable through the elongated holes in order to detachably connect the contact surfaces to one another.
- the fastening element can preferably be in the form of a double T. This achieves an advantageous and preferably detachable coupling of the formwork interface and the attachment interface.
- the form-fitting connection between the formwork interface and the attachment interface using the fastening element can preferably be achieved by inserting the fastening element in an alignment with the elongated holes into the elongated holes and then rotating it by preferably 90 degrees, so that one crossbar of a T is attached on the inside the respective elongated hole rests and thus the fastener is no longer executable from the elongated holes.
- a connection between the formwork interface and the attachment interface can also be produced by a screw connection or other method familiar to the person skilled in the art.
- the fastening element can be materially connected to the contact surface of the attachment interface or the formwork interface and/or the second gripping arm can have a projection which is designed and arranged in such a way that rotation of the fastening element is limited by the projection.
- connection of the fastening element to the attachment interface or the formwork interface can preferably be produced by welding or riveting. Other connection options are also conceivable here.
- the fastening element is materially connected to the attachment interface and positively connected to the formwork interface, rotation of the fastening element relative to the formwork interface preferably being prevented by the projection of the second gripping arm.
- the contact surface of the formwork interface can be formed by an angled surface of one of the first gripping arms and/or the contact surface of the attachment interface can be formed by a base of a rail with a U-shaped cross section.
- the contact surface of the formwork interface can preferably be formed in that one of the first gripping arms is angled at its end facing away from the clamping jaw.
- the contact surface of the formwork interface, which is used to connect the attachment interface, can be formed after the bend.
- At least one of the add-on part interfaces can have a hole for attaching an alignment support.
- the bore or the attachment interface for the push-pull support can preferably be formed in at least one of the first and/or the second gripping arms.
- the hole can also be used, for example, to fix tools by means of a carabiner or the like.
- the attachment interface for the push-pull support can also be realized by another fastening option, for example the attachment interface can be designed as a hook or angle.
- Claim 16 specifies a system for forming a wall element, comprising at least one formwork panel and at least one connecting component, the formwork panel having a frame with a plurality of Longitudinal struts and a plurality of transverse struts, the longitudinal struts and the transverse struts being arranged essentially perpendicularly to one another, at least some of the longitudinal struts and/or the transverse struts having at least two grooves which run in the longitudinal direction and on opposite side surfaces of the respective longitudinal strut and/or transverse strut and wherein the connecting component is a connecting component according to one of claims 1 to 15 and/or one of the embodiments described above, wherein the gripping arms of the connecting component engage in the at least two grooves of a respective longitudinal strut and/or transverse strut.
