Schaltisch

Technical field

The present invention relates to a kind of prefabricated Schaltisch, it is in the template of building field especially for floor.

Background technology

If with the floor floor/top of concrete casting building, build the formwork that a substantial horizontal is provided with so, its edge surrounds by so-called end face template.Formwork can form by a plurality of templates, and they are laid on the so-called crossbeam, and crossbeam is placed in again on the so-called longeron vertical with it.Usually longeron at a plurality of positions by so-called floor (Decke) bracket supports on ground, bottom.

By the known a kind of slab form platform of EP0945564A1, because it is made in advance, formwork is fixed on the crossbeam with the form of a plurality of templates, and crossbeam is fixed on the longeron.On longeron, also be provided with can with the coefficient Connection Element of Connection Element that is arranged on floor support upside.By the prefabricated unit of forming by template, crossbeam and longeron the modular component that only need be equipped with support again can be set, so that and the complete slab form of other this element formation.Prefabricated element particularly can be saved time and expense ground is rotated between each floor, so that water the floor of tier building successively.

By the known a kind of similar slab form device of DE10056831C1, wherein longeron is formed from steel at least.Support is connected so-called being separately fixed on two supporting frames between the adjacent longeron.

Summary of the invention

The objective of the invention is, a kind of slab form platform is provided, it is improved on its applicability with the effective and efficient manner method.

This purpose realizes that by a kind of like this Schaltisch this Schaltisch has: one is fixed on the formwork on a plurality of crossbeams; At least two steel longerons, described crossbeam is fixed on the described longeron, and described longeron is provided with the hole along its whole length by the spacing of rule basically, the connector that is used for being connected with support is installed in a unique longeron respectively by means of described hole, and can install along the whole length of longeron basically, wherein, described longeron is made up of two section bars, described two section bars interconnect by means of side plate, also are fixed with described crossbeam on side plate.

Therefore have a formwork that is fixed on a plurality of crossbeams by prefabricated molds pallet of the present invention, formwork can for example be made up of a plurality of templates.Crossbeam is preferably made by timber.Different therewith, be provided with at least two steel longerons that crossbeam is fixed thereon.Owing on every longeron, the connector that is used for mounting bracket can be installed, can on longeron, fix the support that needs.This realizes that by such method promptly its whole length of this upper edge of at least two foundation in the longeron of Cun Zaiing is provided with the hole by the spacing of rule.At the fixing described connector in place, described hole.This for example can realize by means of the bolt that passes and fix.Should illustrate that support installing on connector this can be undertaken by the wedge connection.At this moment squeeze into one or more wedges in this wise, they make the tensioning securely of support and connector by means of the top board that is arranged on the support upper end.Should furthermore be mentioned that about connector it also can abbreviate " head ", " connector " etc. as.Mainly be that such element is suitable for as connector on meaning of the present invention, promptly the floor support can be fixed on above it, and itself can be fixed on the unique longeron by means of the hole that is arranged on above it.

Connector is separately fixed at possibility on the independent longeron compares with DE10056831C1 and can produce such advantage by of the present invention, promptly can cancel two supporting frames between the longeron that are fixed on shown in the document.According to the present invention by connector directly being fixed on the method on the unique longeron, can be more simply and make connector inexpensively.In order to improve and the acting in conjunction that can be arranged on the mark on the longeron, on connector, a mark can be set respectively, thereby when two marks alignd mutually, the hole on support and the connector is alignment mutually also.

Basically along the whole length of longeron by regular spaces be provided with the hole produce connector on the one hand can be almost infinitely along the fixing advantage of the whole length of longeron.Can neatly support be fixed on the same Schaltisch thus, as with different slab thickness and thus with different concrete pressure be complementary desired.In other words, the distance between the support can be arranged so that on the Schaltisch that designs identically on demand by support and guarantee to derive fully the power that is occurred.Can more promptly connector be installed on the longeron in addition, bolt be passed the hole on connector and the longeron and fix because for example only need.With compare this and can save time significantly by being screwed into metric system screw in the screw thread in the longeron.

The communicating structure in the hole on this jack stringer also provides such advantage, promptly can fix a large amount of annexes without a doubt on longeron.For example can so-called Support joint be installed in this wise, make and can connect support by the orientation that tilts by the hole so that with Schaltisch not only resistance to compression but also tension be fixed on the ground, bottom and/or carry out adjustment process.Secondly can connect different elements with connecting side plate without a doubt by means of the hole.For example two adjacent forms platforms can be interconnected by connecting side plate.Connect side plate by means of one or a few in addition and can connect a compensation film panel element or a workbench as the Schaltisch stand.But also can be by utilizing for this purpose is arranged on hole on the longeron, and this stand directly is fixed on the longeron.Connect side plate and also can make gusset, and be used for fixing longeron by this way to form so-called joist (Unterzug).Here relate to the template part that is in than on the low height of original slab form height.Should illustrate in addition, for by the longeron hole of Schaltisch of the present invention, be preferably the spacing of the spacing of the wall gooseneck (Stahlwandriegel) that its setting is equivalent to use always.Here mainly be meant the beam that is formed from steel of wall form element.By adopting the common spacing between the hole in new ways, for can adopt the annex that has been verified in the wall form field in a large number by Schaltisch of the present invention.Therefore enlarge the common possibility of using of Schaltisch and other form element on the whole, and realized higher flexibility when using Schaltisch effectively.It is noted that, one or more frame elements rather than single support can be set on Schaltisch, described frame element is born function and/or middle connection mode pallet and each support of a plurality of supports.

Longeron preferably has at least one U-shaped section bar.Wherein " bottom " of U-shaped is substantially perpendicular to the formwork orientation usually, thereby goes up the described hole of formation in described " bottom ".The branch of U-shaped can be advantageously used in and interconnect being connected and the supporting of crossbeam on longeron of two U-shaped section bars and/or longeron and crossbeam.In addition particularly the U-shaped section bar dorsad the branch of formwork can be used for fixing the clamping of device.In this case by being arranged to make this tension element to be bearing in the described branch plate-like tension element of a fastening devices, for the thought of having considered by Schaltisch of the present invention from the wall form field.

Alternatively or as to this replenish, longeron can have at least one forming tube.In this form of implementation, also can realize a kind of favourable moulding of longeron.

As mentioned above, preferably make it be equivalent to pitch of holes set on the wall girder steel for pitch of holes.Obtain thus this new Schaltisch with from the described favourable compatibility of a large amount of parts in wall form field.

Set visually visible mark preferably within the scope of the invention in addition each hole.For example can be used for installing the hole of connector with special mode mark with " standard state ".Here standard state is meant, is used for reaching the formwork of certain thickness floor to a certain extent by the study plot supporting with this state.Just when floor is thicker, just must adopt other and/or other hole, so that be provided for being installed in this case connector than the support of under normal conditions, Duoing with the less spacing of needs.At this moment can use the used hole of suitable manner mark equally.Can distinguish different hole groups mutually by different colors, described hole group can be respectively under specific circumstances-promptly under the maximum load that allows separately-select for use.Certainly also can imagine in this case and only be provided with for the essential hole of specific situation.But can improve flexibility in use by additional hole is set, at this moment, as mentioned above, the employed under specific circumstances hole of mark is preferred.At last can be with special mode mark in the hole at longeron middle part, so that show to the staff, here be the center, and have the limited supporting width that is used for longeron be used for raising Schaltisch so that the shift unit of displacement will be installed in this center, topple over to avoid Schaltisch.Should illustrate in this case,, the mark that needn't set to single hole can also be set as replenishing or possibility of above-mentioned mark.Described mark for example can be as the supporting mark, showing, at which situation template platform can prop up on the Schaltisch that is placed on below it, or can prop up on Schaltisch on which position and put other Schaltisch.

In order to adopt from the basic connection possibility in wall form field and fixing possibility as far as possible in extensive rangely, longeron preferably is made up of two section bars in addition, and described section bar at a distance of 15cm or still less.10cm or still less preferably, particularly about 5cm.Two section bars can be respectively " bottom " opposed U-shaped section bars.These bottoms also can be called web, and the branch of the U-shaped that stretches out from the bottom also can be called flange.So corresponding longeron is formed by two such section bars, consequently does equally with so-called wall girder steel in the wall form element basically.Thus can be advantageously on the beam of making by this way, realize through the connection possibility of checking and fixing possibility.Two section bars of the beam of making by this way nearer setting mutually provide such advantage, and promptly needed intermediary element and supporting frame transmit desired power till the order so far.Should be noted that especially that in this case a Schaltisch may be from support to the bigger moment of beam transmission under the state that the free end of the support long by several meters lifts from ground, this is advantageously born by the branch of the formwork dorsad of U-shaped section bar respectively.

For the structure that described longeron is made up of two section bars, it is preferred that section bar interconnects by the side plate that also is fixed with crossbeam thereon, and side plate can have ribs, and for example can be welded on two section bars of longeron.The connection of crossbeam can be undertaken by the hole that forms on side plate and crossbeam respectively.

Connector preferably is removably mounted on the Schaltisch.Thus by connector is pulled down from platform, can realize for the transportation of Schaltisch and deposit the stacking in special saving space.Connector can be especially rapidly and is dismantled easily and retighten, because for example only need to insert or knock in for example two pins of each connector for this reason.Thus save the stacking of ground, space in order to transport and to deposit after, can make the land used scene promptly finish supporting by Schaltisch of the present invention, save the stacking of ground, space for transportation and for example produce such advantage, promptly only need less transport space, thereby and can reduce freight.

Although only be to be fixed on the connector that being used for above it is connected with support for the important part of Schaltisch of the present invention, in the scope of a kind of preferred form of implementation of the present invention, to imagine, at least one connector is designed to swing.This provides such advantage, promptly needn't pull down the support that is contained on the Schaltisch in order to save the space, but it can be swung in this wise, so that it favours and/or almost to be parallel to formwork ground directed.Schaltisch of the present invention can transport and deposit with the methods of saving the space with the formwork parallel orientation time.This external such can also be when directed from building, as the back also will describe in detail, even from building, shift out the very little opening.When support is arranged at least obliquely, by for example with Schaltisch from one deck of having built up by the window of an architectural openings-for example or balcony revetment-shift out, can move Schaltisch to be positioned at its top that one deck that will build its floor from one deck.This process also can be undertaken by adopting a so-called swing head not tear support ground open.Particularly, make the present invention can use longeron with less structure height because the connection between connector and the longeron can design to such an extent that obviously be different from this fact of prior art.This structure height is preferably 12cm at present.

For described swing head, it preferably has one and is provided with one and is used for support is fixed on locking plate or the handle (Klinke) of showing locational eccentric curve.The position of showing in this case is interpreted as the position of support to become about 90 a ° angle to extend with respect to formwork.Described handle is arranged on the swing head swingably, and can by means of the described eccentric curve that for example on a hooked projection, forms with a pin or bolt in this wise conjugation on counterpart, promptly realize counterpart more and more is pressed on the longeron by handle being rotated to the lock position.One support for example can be fixed on the described counterpart by a wedge mechanism, thereby reliable especially thus and firmly fix support.

In addition for handle, it is preferably in the possibility that the position has a locking that swings in of support.Swing in the position that the position is interpreted as that support tilts or also can extend abreast with respect to formwork.For example it is contemplated that 10 ° position locking,, thereby can for example Schaltisch be displaced to the one deck that is positioned at its top by the window on the building with the orientation that realizes that Schaltisch obviously dwindles at a support (with respect to formwork).One is used for locking that support is parallel to the orientation of formwork and can be thought of as and deposits and transporting position in addition.

Secondly if handle is shown the position of support and is bent away from from a support that is fixed on the connector, is favourable for handle then.Handle is not one directed to protrude from the downside of Schaltisch below tiltedly when this structure, but is fitted on the Schaltisch owing to the trend of bend to a certain extent.Prevent the obstruction of working thus in the connector zone.In addition since like this " applyings " especially little in the structure height of Schaltisch patrix pallet, thereby a plurality of Schaltisch can be saved space ground stacking especially.

Can realize other advantage by connector in the form of implementation that its downside has at least one softer supporting bed.Because form the downside of Schaltisch at the downside of the state connector of the support of dismantling, can be by the good stackable property of described supporting bed realization.Be on the formwork of the Schaltisch Schaltisch that can utilize soft supporting bed to be seated in to be positioned at its below, and do not have the danger that damages the formwork that is positioned at the Schaltisch below it.Softer in this case being meant, supporting bed for example are made up of plastics etc., thereby avoid the damage that causes on the formwork of being made by timber owing to an element that is formed from steel being placed on usually.Should illustrate that for the above-mentioned connector of swinging that also can be described as the swing head it also can be independent of Schaltisch of the present invention and bring into play its advantage.Therefore will describe the swing head that is used for connecting between floor support and the beam as content independently, it both can be by steel, also can make, and this swing head can have any combination top and feature given below by timber or any other suitable material.

As mentioned above, Schaltisch of the present invention particularly with the compatibility of different annexes and connectivity on have its advantage.Therefore imagine in a kind of scope of particularly preferred form of implementation, described Schaltisch is provided with at least one and connects side plate and/or at least one retaining element (Verankerungselement) and/or at least one stand.This has reflected several different expansion possibilities of Schaltisch according to the present invention and the possibility that a plurality of Schaltisch that are provided with are abreast mutually linked together.As mentioned above, the direction along longeron can connect by suitable connection side plate.On the direction vertical, can adopt the retaining element that passes the hole insertion that is arranged on the longeron with above-mentioned direction.This is external to utilize under the situation in hole on the longeron and can prevent that annex one from for example dropping along the retaining element one perpendicular to the setting of formwork direction.

Above-mentioned feature of the present invention can be used arbitrarily in combination, and formed thus technical scheme all belongs to scope of the present invention.
