Description

Detailed Description of the Invention

The present invention relates to polygonal building panels and building structures containing such panels.

It comprises first and second sheet metal dish-shaped bodies each having a central portion which substantially forms a polygonal edge portion and a bent edge flange bent inwardly of the panel surface. The flange of one of the dish bodies engages in the flange of the other dish body, and the heat insulating core fits into the body of the dish body, which is usually glued or by molding the core directly inside. Many forms of installed building panels are known. The profile engages the inwardly facing flange portion of the panel to provide lateral edges to the panel so that the panels can be attached to each other and to the support structure.

Known panels are generally sufficient for interior applications, but when used as exterior materials, they are subject to much greater forces, especially those due to the weather such as wind, and the known constructions are therefore totally for this reason. Not enough.

According to the present invention, the above-mentioned weaknesses of the conventional panel can be overcome, and therefore, the present invention provides that the polygonal edge portion includes the first central portion and the polygonal edge portion. A first sheet-shaped metal dish-shaped body having a first bent edge flange on a side, and a second central portion having a shape similar to that of the first dish-shaped body but having a smaller covering area and a second central portion. A second sheet metal having a second bent edge flange on each side of a polygonal edge portion sized to fit closely along the first bent edge flange of the first dish-shaped body A dish-shaped body and a core structural material that substantially fills an inner portion formed by the first and second central portions and the second bent edge flange, and the first bent edge A part of the flanges is bent in the direction that intersects the other bent edge flanges and is approximately in the center of the dish. A row of projecting edges, and further a bar-shaped piece in the middle of a predetermined cross-section for engaging and positioning the first and second bent-edge flanges, the bar-shaped piece Providing a building panel characterized in that it has an abutting portion that engages the side surface of the portion, and that the first dish-shaped body and the intermediate rod-shaped portion hold each other. Is. Further, this building panel realizes a building panel structure by being integrated with a supporting structure material.

Preferably, the intermediate rod-shaped piece includes a laterally protruding joint of the panel which engages a side surface of the upper edge portion so as to press the dish-shaped body corresponding to the core.

By providing such a joint on the bent edge flange that engages the edge, the edge is prevented from being pulled outward from the panel surface by the wind. It is preferred that the laterally projecting edge of such a panel be provided at the edge of the flange corresponding to the outer dish.

The matable bent edge flanges preferably have intermediate bar-shaped members that engage on both the inside and outside of the panel.

In the preferred construction, the intermediate bar-shaped piece preferably has a portion engageable with a fastener used to clamp the panel to the support structure. It is desirable that this portion presses the rod-shaped piece in the direction in which the joint is pressed against the edge when the fastener is tightened. In this way a fastener can be used to hold the two dish-shaped bodies firmly against the support structure and slightly tighten the core sandwiched between them.

The fastener may be, for example, a screw type fastener in combination with a washer-like rotatable member, the rotatable member engaging at least an outwardly facing mounting surface formed on said portion of the bar-shaped piece. It is preferable that one groove is formed.

Frequently, rod-shaped pieces of a given cross-section are arranged in a mirror image so that a fastener corresponds to each rod-shaped piece of two adjacent panels. The rotatable member rotates to a position where the second panel can easily take a position close to the already fixed panel, and then the rotatable member rotates by, for example, 90 ° so that the rotatable member becomes the second member. It may be a partial circle in which a part of the peripheral portion is omitted so as to engage with the panel portion.

In another form, the fastener is shaped to have a contoured head engageable with the above portion of the intermediate bar.

In fact, according to another aspect of the invention, there is provided a support structure and a central portion where each panel forms a polygonal edge and a first bent edge flange on at least one side thereof. A plurality of panels having a first sheet metal dish, a second central portion having a similar shape to the panels and a second bent edge flange on at least one side of a polygonal edge portion; A second sheet metal dish-shaped body;
Core structure that substantially fills the inner portion formed by the bent edge flanges and an integral flange that has the first and second bent edge flanges engaged and positioned with each other and having a bent ridge It consists of a rod-shaped piece in the middle of a predetermined cross section and a plurality of fasteners including a head and a fastener that each engage an integral flange, the integral flange is slidable with respect to the head, and the fastener is a support structure. Features a building panel structure having a portion shaped for mounting and further having locking means for locking the fastener to the integral flange.

In such a fastener, the head portion of the fastener is abutted against a part of the intermediate rod-shaped piece to be engaged with a locking means having a screw which is fastened so as to lock the intermediate outer shape portion with respect to the fastener. It has a hole that can be pressed. In short, it is preferable that the body portion of the fastener includes a notch that can be engaged with the support member of the support structure.

Filling strips may be disposed between adjacent panels of each pair. This may be of a grooved sheet metal construction, with the gasket first facing inward when the filling member is forced into the space between two adjacent panels. To provide a weatherproof seal between the flanges, then grooved to have an engaging portion that engages behind the mating ridges formed in the two corresponding intermediate bar pieces. A gasket may be attached to each side of the flange of the filling member.

This is, so to speak, with respect to the first bent edge flange, although the edges of the first and second inwardly facing flanges are usually bent outward from their corresponding cores. However, it is conceivable that the second bent edge flange may have a bent edge extending laterally of the panel.

In the preferred construction, the edges are formed on alternating flanges and not on the intermediate flanges. For example, most commonly the panel is rectangular, in which case two opposing first flanges have edges and the other two marginal flanges have no edges. In that particular embodiment, the second flange in mating relationship with every other flange does not have an edge while the other flange has a bent edge. Would have. Also, the polygonal shape may have a different number of sides, for example the polygonal building panel may be hexagonal, where again every other first flange faces the panel front. It may be preferable to have the edges provided and not the other three flanges.

In order that the present invention may be more readily understood, the following description is given, by way of example only, with reference to the accompanying drawings. 1 and 2 show a curtain wall cladding system for a building according to the present invention. More specifically, the portion at the location of the joint between the horizontal and vertical members is shown.

A load-bearing building frame or structure 10 having a front flange or web 12 comprises a plurality of individually removable and interchangeable panels 1.
4 is used as a mounting body. The load-bearing frame can consist of any number of parallel, spaced-apart elongate profiles of L-shaped, U-shaped or H-shaped cross-section with one flange exposed at the front for mounting the panel. Each panel 14 has upper and lower horizontal flanges 2 that rigidly secure a bar of predetermined cross section that forms the edge of the panel.
It is mounted by a rotatable member 16 and a screw fastener 18 that engages zero.

The panel itself has a first outer sheet metal dish 22 and a second inner sheet metal dish 2
4, a lightweight core structural member 26, and intermediate horizontal and vertical reinforcing rods 28 and 30. The horizontal flange 20 is integral with the horizontal rod 28. Also integral with each of the rod-shaped pieces 28 and 30 is an outer groove 32, which is open towards the outer surface of the panel, into which the rod-shaped piece of the filling member, indicated schematically by 34, can engage. The rod-shaped piece 34 of the filling member comprises an elastic gasket 36 and a rigid sheet metal groove-shaped outer strip or body 38.

The attachment of the panel 14 to the load bearing structure 10 is accomplished by a member 16 and a fastener 18 whereby a raised portion of a flange 20 is provided on the rear surface of the rotatable member, as shown more clearly in FIGS. 2-5b. Article 42
Parallel recessed grooves 40 are provided which are adapted to engage above.

The cross-sectional dimension of the groove 40 in the lateral direction is shaped so as to exceed the cross-sectional width of the ridge portion 42 in order to provide some dimensional difference and tolerance during thermal expansion and contraction. ing. A roughly circular rotatable member 1
6 is a flat side portion 44 which is rotated to fit one flange 20 so as to pass other rod-shaped pieces while holding other cross-sectional shaped pieces during installation.
have. This feature is particularly shown in Figures 5a and 5b, where the screw fasteners and the load bearing structure have been omitted for clarity.

FIG. 4 shows in detail a cross section of the filling member in the horizontal direction in which the panel 14 and the rod-shaped piece 34 of the filling member are properly installed. The screw fastener 18 shown in the example is of the type having a piercing end 46 and self-tapping screw 48 so that several steps are performed in a single operation. It will be appreciated that any type of threaded fastener may be used provided that the thread 48 is long enough to be loosened and rotated over the ridge 42 while retaining the member 16 on the load bearing structure. Let's do it.

FIG. 4 shows that the rod-shaped piece 34 of the filling member engages with the groove exposed to the outside of the intermediate rod-shaped piece 28. To further explain this structure, reference is made to FIG. 6 which shows a cross section of the filling member in the vertical direction and to FIG. 5c which shows the rod-shaped piece itself of a predetermined cross section of the filling member. A quick comparison of FIGS. 6 and 4 reveals that there is no panel mount on the vertical fill member.

The filling member rods 34 are pressed from the outside of the structure and the gasket 36 and the rigid body 38 are both slightly variable constructional tolerances with some variable spacing between adjacent panel grooves 32. It has enough elasticity to fit in. The gasket 36 shown in FIG. 5c has a transverse panel airfoil 50 which provides a weather-proof seal against a first bent edge flange 52 of the dish-shaped body on the outer side of the panel. The gasket bar is also provided with a bent lip 54 which grips behind the rib 56 in the outwardly open groove 32 to hold the filler bar 34 in place.

FIG. 5c shows the rod-shaped piece of the filling member in the loosened form. FIG. 6 shows a cross section of the filling member in the vertical direction,
4 shows a cross section of the filling member in the horizontal direction. Further, it can be seen from FIGS. 4 and 6 that the edges of the panel in the vertical and horizontal directions differ from the panel surface. It can be seen that the sheet metal outer dish 22 at the horizontal panel edge shown in FIG. 4 has a bent edge flange 52 with an edge 58 projecting laterally of the panel.

The intermediate bar 28 in the horizontal direction is provided with a joint in the form of a ridge 60 in a groove 32 open towards the panel outer side, which ridge is of the dish-shaped body on the outer side of the panel. It can be engaged and retained above the laterally projecting edge 58. As a result, the dish-shaped body on the outer surface of the panel is structured to receive the load and is securely held, so that the curtain wall structure can withstand an excessive wind suction force. Thus, the connection to the dish-bearing structure of the panel outer surface is not subject to chemical degradation as would be the case if the sheet on the panel outer surface was simply held and secured with an adhesive.

The bent edge flange 52 at the edge of the vertical panel as shown in FIG. 6 is formed so that there is no edge projecting laterally from the panel surface.

FIG. 7 shows the panel in a slightly simplified and broken configuration. Not shown in FIG. 7 is the core member 26 covering substantially all of the inner major surface of the dish on the inner and outer sides of the panel and interconnected with an adhesive, but part of the assembled structure. Will be

However, both the rigidity of the assembled panel and the flatness of the relatively thin wall-like outer surface depend in particular on the uniform connection with the core and its structural rigidity. The purpose of FIG. 7 is to describe an assembly or panel structure of dish-shaped bodies on the inner and outer surfaces of the panel and the panel surface and horizontal and vertical intermediate reinforcing bar pieces.

The rod-shaped pieces 28 and 30 in the middle of the panel surface in the horizontal and vertical directions have substantially the same cross section, but differ in length and end shape.

As shown in FIG. 7, each of the intermediate bar-shaped pieces has a dish 22 on the outside surface of the panel when assembled.
Has a main surface 62 that engages the inner surface of the bent edge flange 52. This intermediate bar piece also has a main surface 64 which engages the outer surface of the second bent edge flange 66 of the dish 24 on the inside surface of the panel when assembled. The sheet-shaped metal dish-shaped body 24 on the inner surface of the panel has a central portion 25, which is similar in shape to the central portion 23 of the sheet-shaped metal dish-shaped body 22 on the outer surface of the panel. The inner side dish has a slightly smaller area to fit over the folded edge flange 52 of the panel outer side dish to provide space for the intermediate rods 28,30.

Each of the intermediate rod-shaped pieces 28, 30 is also provided with a groove 68 which opens towards the dish-shaped bent edge flange 66 on the inside surface of the panel. The free ends of the folded edge flanges 66 of the pans on both the inner and outer sides of the panel engage grooves such as 68 or 32 respectively, but the load and force exerted on these pans is intermediate. Is transmitted to the rod-shaped part of the structure, and is thereby transmitted to the structural material that receives the load.

From a safety point of view, particularly in a structure which is relatively maintenance-free, such as a curtain wall of a building, the joint portion of the structure is easily subjected to the chemical deterioration action, and therefore the adhesive material is applied to the joint portion. Obviously it is preferable not to use only. The panel of the building according to the invention provides a secure mechanical locking of all its parts, especially when it is mounted on a load-bearing structure as described above.

Of particular importance in this regard is the panel assembly sequence, which is as follows. That is, first of all, in the panel structure, a corresponding horizontal flange 52 of the dish-shaped body 22 on the outer side of the panel is attached to the horizontal outer shape portion 28. In the panel structure, the horizontal bar-shaped piece 28 is rotated about the vertical axis of the panel surface to guide the lateral edge 58 of the panel surface to the rear of the ridge 60 of the groove 32. Made by putting in.

As shown in FIG. 7, the groove 68 of the horizontal profile portion 28 is cut shorter than the other portions of the bar-shaped piece above the portion 70. The recesses 70 are aligned with the opposite ends of the grooves 68 of the adjacent vertical profile portions 30.

After inserting the vertical bar 30 of the panel surface between the opposing horizontal contours 28 of the panel surface, the bar 28 is no longer disengaged from the edge 58. Horizontal and vertical bar pieces 2 on the panel surface
After 8 and 30 are placed on the dish-shaped body on the outer side of the panel,
The preferably lightweight core structure is now ready for insertion into the inner portion of the dish 22 on the panel outer surface formed by the intermediate member. This core structure is not shown in FIG. 7, but any suitable foam such as preformed blocks or slabs of expanded polystyrene, expanded polyurethane, mineral wool, or other suitable material, Alternatively, a preformed cell-shaped core such as a honeycomb structure may be used.

To complete the "sandwich body", the free end of the bent edge flange 66 faces the free end of the bent edge flange 52 of the dish-shaped body on the outer side of the panel, and there is also an intermediate bar piece. The dish-shaped body on the inner surface of the panel is inserted so as to enter the groove 68. The central surface 25 of the dish on the inside of the panel is adhered to the core and thereby to the major surface 23 of the dish on the outside of the panel, holding the entire assembly together. Such a sandwich structure is very advantageous because it enables a large area panel without using a heavy metal plate.

Flatness is usually important for large area panels, and any defects in this flatness directly impair the visual aspect of the wall cladding. The sandwich panel according to the invention is lightweight so as to provide flatness, enhance the mechanical strength of the installation and reduce the cost of the support structure.

The details of the corners of the positions taken by the rod-shaped intermediate pieces in the vertical and horizontal directions on the panel surface are further shown in FIG. Different ends of the horizontal middle bar 28 and also the vertical middle bar 30 in the panel plane as seen in the particular (more sophisticated) profile of the preferred embodiment of FIGS. Are shown in Figures 9a and b respectively.

FIG. 10 shows a modification of the panel, which is not rectangular but hexagonal in this example. The form of the panel assembly is similar to the embodiment of FIG. 7, but in this example,
Three "horizontal" type bar pieces and three "vertical" type bar pieces alternate along the six perimeter flanges of the panel.

An alternative configuration is shown in FIG. 11 in which the assembly includes an intermediate bar having two opposing bent edge flanges 66 of the dish on the inside surface of the panel, somewhat similar in shape to the groove 32. It differs from that of FIG. 7 in that it has a bent edge 72 which is assembled to have a groove 74 in the piece 30.

Obviously, the latter modification requires a slight adjustment to the assembly procedure in that the "vertical" type bar piece 30 is here assembled integrally with the dish-shaped body 34 on the inside surface of the panel. And

12 and 13 show the mounting structure shown in FIG.
4 shows another embodiment different from those of FIGS. 12 and 13 show horizontal and vertical cross sections of the filling member in the vertical direction on the panel surface. This embodiment is characterized in that the vertically loaded structural member 110 corresponds to the vertical filling member, and the panel is oriented in the vertical direction of the panel rather than the horizontal filling member of the panel as in the first described embodiment. It can be attached to the filling member.

Apart from having a different intermediate profile 120, the pans on the inner and outer sides of the panel are also 90
Can be turned by ° to make horizontal edges vertical edges and vice versa.

FIG. 12 shows lateral edges 58 and ridges 1.
It is shown that 60 is arranged on the vertical filling member.

FIG. 13 is a sectional view taken along the line XIII-XIII in FIG. 12, but the panel 114 descends and is mounted on the bolt 115. A hook-shaped member 117 connected to the panel 114 is engaged with the bolt 115 by an enlarged head 119 that fits into the recessed groove 121 of the intermediate rod-shaped piece 120.

As shown in FIG. 13, the hook-shaped member 117 has a recessed groove 121 cut by a fastener 123.
Can be held at

An elastic member 125 may be additionally provided to provide a snug, mated and unmated connection, which snaps onto the bolt 115 and further includes a detent 129 on the hook-like member 117. There may be additional means 127 for engaging the rear as well.

The support structure 110 is preferably in the shape of a top hat and preferably has a lateral surface 112 of the panel surface for supporting the rear surface of the panel.

Elastic padding in the form of strips 113 may be provided between the surface 112 and the inner panel surface.

The embodiments of FIGS. 12 and 13 are generally preferred for installations in which the rectangular panel is oriented with its long direction vertically on the panel surface, and the embodiments of FIGS. 1-4 are horizontal on the panel surface. Would be preferred for rectangular panels of.

FIGS. 14 to 17 show another embodiment of the present invention in which an intermediate outer shape portion substantially similar to that of FIGS. 1 to 4 and a mounting form generally similar to those of FIGS. 12 and 13 are modified. The example of is shown.

In detail, the support structure 210 is very similar to that of FIG. 12 and includes a transfer bolt 215. First
Dish-shaped body 222, second dish-shaped body 224 and core 226
Two panels having a tab are shown mounted adjacent to each other (FIG. 15), each including a body portion 217, an enlarged head 218 and a downwardly extending notch 219 engageable on a bolt 215. It is held in contact with a fastener 216 (FIG. 16).

From FIG. 15 the head 218 engages in the recess 227 of the corresponding intermediate rod-shaped piece 228, which recess corresponds to the head 2.
It will be appreciated that it includes a folded rim 229 for engaging the underside of 18.

The head 218 has at least one screw hole 2
50 is provided, and the locking member 252 is screwed to this, and when the locking member 252 is screwed, it engages with the intermediate rod-shaped piece 228 and between the intermediate rod-shaped piece and the fastener 216. It is locked so that it does not move relatively. As can be seen from FIG. 16, the screw holes 250 of the two fasteners are on the panel surface of the head and are offset from each other in the vertical direction. This facilitates the operation of the spanner with the locking member. In this way, the height and position of each panel 214 can be adjusted to suit particular needs. The other side of this configuration is similar to that shown in FIG. 4, and the assembly also includes a rod 234 and gasket 236 of the filler member.
You can see that is provided. These can be removed so that the aging member 252 can be tightened and loosened with a suitable spanner.

This form of tightening is not only used for structures of the type shown, but other panels provided that the fastener head has some form of edge profile that can be engaged and locked. It will be understood that the above is equally applicable to.
