Lifting means and method

The present invention relates to promote the equipment and the method for building element or corresponding tabular component, these members to small part comprises the core and the plate-like surface layer that covers two sides of core that are made of elastomeric material, and this superficial layer is at least in a member edge bend into a part of thickness of core.

The building element of available equipment lifting of the present invention for example can comprise an elastomeric core, this core is for example made by mineral wool fiber, each flat surface of core all is coated with the layer of metal thin slice, and this sheet metal is be bonded to this mineral wool board lip-deep.For fear of the damage of plate, must be careful careful when handling this building element, can not use existing clamp jaw type lifting means to promote these plates.In order to promote said thistle board, developed various different types of clamping parts, these clamping parts are to fill up on the flat surface that is fixed to building element by inhaling.

No matter how light it is that these plates that will promote have, the number of inhaling pad all must be quite big, only in this way could guarantee enough big improving safety, could will may disturb the fixing numerous influence factor of suction pad to take into account.Have, the clamping part of lifting means need have an enough big clearance envelope in lip-deep certain position of plate at least again, and this position is exactly that fixing device is fixed to position on the flat surface of plate to be hoisted.

Just can eliminate said these shortcomings by means of equipment of the present invention and method, it makes to clamp at the edge of plate becomes possibility, in certain embodiment even in the required space of the thickness of plate along continuous straight runs clamp and become possibility.

According to one aspect of the present invention, a kind of equipment that promotes building element is provided, this member to small part comprises an elastomeric core, and superficial layer that covers these core both sides, this superficial layer stretches out with the cover part core on a member edge at least, and this equipment comprises a rack construction, at least one passes that frame is extended and with respect to frame rod unit movably, one is arranged on an end of rod unit and the clamping part that can insert below the superficial layer above the core, an other end that is arranged on rod unit is used for rod unit is locked the locking member of a raised position, and be used for rack construction is supported on parts on the superficial layer of opposite side of member to be hoisted.

According to another aspect of the present invention, provide a kind of method that is used to promote building elements of panel.This member comprises an elastomeric core layer and the superficial layer that covers these core layer both sides at least in part, on an edge that has at least a superficial layer at member on this member, stretch out a part, the method is characterized in that this member is from clamped below a tectal crimping that extends above the edge of core layer with a corresponding edge that covers core layer.

By means of accompanying drawing the present invention is described below, wherein:

Fig. 1 represents a member to be hoisted, places an equipment of the present invention that is in the initial secured step in the top edge of this member;

Fig. 2 represents unidirectional member to be hoisted, the state when expression is fixed to raised position with equipment of the present invention;

Fig. 3 represents the member of flat surface direction, and expression is with the situation of lifting means when raised position is fixed to top edge;

Fig. 4 represents the applicable cases of the present invention when promoting roofing element.

Such building elements of panel of available equipment lifting of the present invention comprise a core 8 and cover the plate 9,9 of core both sides ', the thickness of core 8 accounts for the overwhelming majority of member thickness.Core 8 for example can constitute by having suitable intensity cushion of mineral wool, with this core 8 of sheet metal cover.

In order to realize a kind of connected structure, the top edge of the wall structure of Fig. 1-3 is such design, makes each wrapper plate 9,9 ' stretch out certain distance and bend towards core above core 8, so that stretch out a crimping along the length direction of member.Bead structure is stretched to the core certain distance of member, but does not cover the main portion of core 8 top edge.In the embodiment shown in the figure, each crimping is at joint tongue 10 of vertical formation of plate, and joint tongue is corresponding therewith in the lower edge of next member a groove that connects.

In the roofing element of Fig. 4, the design trip edge is departed from out itself and wall structure.The wrapper plate 9 that forms this member lower surface partly extends in the top of core 8 corresponding to wall structure, but the wrapper plate 9 of formation upper surface ' outwardly-bent successively, so that between the panels of two placements close to each other, form a water seam.Also have, the tenon groove structure of the tenon groove structure 10 of this lower surface ' promote the edge with wall structure staggers mutually, and the tenon groove structure (it has a longitudinal slot) of the lower edge of in fact best and wall structure is corresponding.

At first, the inventor's lifting means comprises a crossbeam 1 that forms frame.The crossbeam width that is used to promote the lifting means of wall structure preferably conforms to the thickness of wall structure.Under the contrast, the width of this frame member that is used to promote roofing element is just not too important.At the lifting means that is used for promoting wall structure, the length of this housiung separator 1 can be selected; But at the lifting means that is used for promoting roofing element, the length of housiung separator but is to be determined by the thickness of roofing element to be hoisted.Have at least a clamping unit will be assemblied on this housiung separator 1, this clamping unit comprises an axle (or corresponding parts) 2, this 2 hole that preferably is placed in the midway location that is arranged in housiung separator 1 width.In the hole, leave axle 1 mobile space, make this axle 2 not only rotatable but also can vertically move along housiung separator 1.

At the other end of axle, along a clamp jaw 3 longitudinally being set perpendicular to the axle y direction.At the lifting means that is used for promoting wall structure, determine the size of pawl 3 by the width of clamp jaw 3, pawl 3 can be placed in the intermediate space that the crimping by surface plate 9 stays, thereby pawl 3 arbitrarily can be pressed against on the top edge of core 8.Determine the size of pawl 3 by the length of clamp jaw 3, when making pawl 3 with respect to this member vertical, carry out lateral rotation, pawl 3 tensible at least but preferably makes pawl 3 tensibles be shown under the crimping of two tenon groove structures 10 by Fig. 1 and 2 under a tenon groove structure 10.At the lifting means that is used for promoting roofing element, clamp jaw 3 is side-prominent from axle 2 only preferably, and come to determine the size of pawl 3 like this so that the position of axle 2 is taken into account by the length of pawl 3, thus make pawl 3 extend in the tenon groove structure 10 of this member lower surface ' crimping under.

At the lifting means that is used for promoting wall structure, the lower surface of housiung separator 1 is such design, makes this lower surface can cooperate the upper surface of member to be hoisted, forms vertically admittance groove at joint tongue shape 10 on housiung separator.At the lifting means that is used for promoting roofing element, do not need these joint tongues and groove, but the suggestion on housiung separator 1 end that comprises clamp jaw 3, be provided with a cam 1 ', cam 1 ' the be stretched over side of the clamp jaw of housiung separator 1, determine like this cam 1 ' size make its tenon groove structure that can be assembled to the roofing element lower surface 10 ' groove within.

At the lifting means that is used for promoting roofing element,, be used to clamp the water seam 12 of roofing element upper surface at special clamping part 11 of end assembling of housiung separator 1.This clamping part 11 is made hook-like assembly unit, can clamping part 11 be fixed on the housiung separator 1 by axle 2, the fit of clamping part 11 conforms to the fit of the clamp jaw 3 that is positioned at the housiung separator other end.Determine the size of clamping part 11 like this, make parts 11 can the raised brim 12 of water seam ' the rear hook, then housiung separator is fixed to the fixed position of clamp jaw 3, be close to the edge of roofing element.If need not hook-shaped clamping part 11, this structure can also comprise the parts of other type so that clamp member to be hoisted, for example clamp the plate 9 that forms superficial layer ' one inhale pad.

In wall structure lifting means as Figure 1-3, when lifting means was transferred to raised position, clamp jaw 3 at first rotated along the direction of housiung separator 1, then housiung separator 1 is put into the top (see figure 1) of member upper limb.After this, will pass the upper surface that the axle 2 of housiung separator and clamp jaw 3 is pressed onto the elastomeric core layer 8 of this member in the end.This elastomeric core layer can be slightly flexible, therefore may make clamp jaw 3 be pressed into the inside of member, and the size that is pressed into should be able to make pawl 3 reach certain position along the thickness direction of member.In this position, the pawl of clamping part extends in the below (see figure 2) of crooked tenon groove structure 10 crimpings of this piece table surface layer.Lifting bar 5 turns to its position along the direction of housiung separator 1 then, and in this position locking, forms a locking member 6 that is fixed on the housiung separator 1.This locking member loser best and this equipment works simultaneously.

The lifting means that will be used to promote roofing element again is placed on the horizontal position of member to be hoisted in proper order, realized at first that thus the above-mentioned clasp joint at flange 12 ' afterwards of clamping part 11 fixes.After this, with the cam 1 of rack unit ' the be pressed into tenon groove structure of member, pressing against on the elastomeric core layer 8, and allow axle 2 rotate the axle 2 of end and clamp jaw 3 with aforementioned corresponding mode, make clamp jaw 3 tenon groove structure 10 ' crimping below the location.If do not adopt said rotary embodiment, also can adopt following structures at the lifting means that is used for promoting roofing element, make and axle 2 cooresponding parts can vertically moving in an axial clearance of housiung separator along housiung separator.In this case, clamp jaw 3 may be in position as shown in Figure 4, and clamp jaw 3 has at this moment compressed the upper surface of core 8.In the slid underneath of this position pawl 3, and pawl 3 is locked at this raised position by parts as shown in Figure 4 at the crimping of tenon groove structure.

Use supplementary features of the present invention and can guarantee that bont is fixed on the edge of member to be hoisted, by these supplementary features, by means of wedge-shaped surface 4 ' make an articulated section 4 between lifting bar 5 and the axle 2 become a compacting part.When lifting bar 5 forwards level attitude to, can make moving that axle 2 realizes rising slightly by means of these wedge-shaped surface, this rising is moved between housiung separator and the clamp jaw 3 between (being equivalent at housiung separator) and the clamping part 11) clamping element (for example crimping of tenon groove structure and water seam) of locking member to be hoisted is enough usefulness.

The lifting means that is used to promote wall structure preferably comprises that by mode shown in Figure 3 the above-mentioned lifting piece of paired setting is right: axle 2, clamp jaw 3, articulated section 4 and lifting bar 5, they and identical locking member 6 concerted actions.By means of a kind of like this arrangement, can make this lifting means become the instrument of at the uniform velocity coordination.But within the scope of the invention, also have other layout certainly, for example each lifting means only has a lifting piece.Can make the longer dimension of lifting means, make to promote the lifting piece that comprises two or more apart suitable distances is set.

The lifting means that is used to promote roofing element includes only parts shown in Figure 4 naturally, therefore will clamp the member to be hoisted of the certain distance that is separated from each other, and preferably can use several lifting means.

Different with the foregoing description, replace described uniform crossbeam shape frame 1 also can use the rack construction of other type, the case structure that constitutes by flat board for example, or constitute the rack construction of other type by the plate bending, the case structure that constitutes by flat board for example, or the structure that constitutes by the plate bending.The rack construction of various frame-types all is feasible.

If axle 2 is not installed on the frame, so just can use one to pass rod-like members that frame thickness extends, that form by plain mode, directly form a clamp jaw 3 at the one end, and directly form a lifting bar 5, by this rod unit being locked to frame at its other end.Contrast with situation about having described in the past, this rod unit 2 can be installed on the frame 1, for example rod unit is a bevelled with respect to frame, therefore an obliquity, clamp jaw 3 in the rod unit 2 may be pushed below the overplate crimping, and at another obliquity clamp jaw 3 the overplate crimping is locked on the frame, the other end in this position by rod unit is locked to rod unit on the frame.Also can not use above-mentioned lifting bar directly rod unit 2 to be locked on the frame, and for example be locked on the loser 6 in this case, or be locked on certain other the position of frame.

Said parts also can slide with respect to frame, for example in passing a groove of frame, slide, thereby promptly replaced axle/or rod unit 2 or both together rotation and tilt to move.For example in the embodiment of Fig. 4, under the condition of not turning cylinder 2 and clamp jaw 3, can below the superficial layer crimping, push this clamp jaw 3, therefore clamp jaw 3 can be designed to the sledge shape, so that the surface of sandwich layer is moved and avoided damaging in this pushing.

As previously discussed, in many practical applications, it is just enough so that only clamp a superficial layer crimping that lifting means is only installed a structure that is formed by clamp jaw 3 or corresponding rod unit 2.Can in every way the other end of lifting means be supported on the opposite side at member edge, wherein a kind of variation is shown among Fig. 4 as hook-shaped clamping part 11.Can also use the clamping part of another kind of type, for example be fixed to superficial layer 9 ' one inhale mat structure and replace parts 11.If superficial layer 9 ' also above core 8, stretch, so also can at first to insert superficial layer 9 ' be used as a clamping part of superficial layer crimping below, hook or the analogue that goes out to its distal process from frame 1 for example, these parts at first insert the below by a crimping of superficial layer 9 ' form.After this, for example by means of the clamp jaw 3 that below facing surfaces layer 9 crimping, works, with the other end locking of frame by mode shown in Figure 4.
