BODY STRUCTURE

The invention relates to a frame structure as defined in the preamble of claim 1.

5 Today, nail plate gratings are turned into halls and similar large industrial buildings and warehouses in two main ways. In others, nail plate cross-members are used only as load-bearing parts of roof structures and the walls of the building are made of separate beams, columns or the like resting on the foundations 10.

In another known application, the load-bearing structure of both the walls and the roof is nail plate gratings, in which case a curved nail plate structure extending over the space to be built consists of two rigid nail-15 plate truss structures which are hinged to each other as well as hinged to foundations. In this way, a sufficiently strong and computationally manageable entity has been obtained.

However, there are significant drawbacks to the prior art. The articulated structures used limit the free spans that can be achieved and the structures become relatively heavy and expensive. Similarly, where they consist of two parts which must be manufactured industrially using nail plate technology, their transport must be carried out. 25 Kalle is often awkward. There is also the problem that the cross. the distance between the joints must be kept relatively small, on the order of 1 to 2 meters, due to the buckling sensitivity of both the individual rods and the whole structure. ACCURATE. This is not possible in the side walls of buildings: 30 large doorways, which significantly hampers the use of buildings.

.1. The object of the invention is to eliminate the above-mentioned drawbacks. In particular, it is an object of the invention to provide a new type of frame structure utilizing nail plate truss technology: which is more cost-effective and versatile than the prior art for various construction applications.

With regard to the features characteristic of the invention, reference is made to the claims.

The frame structure according to the invention comprises circumferential nail plate trusses acting as a load-bearing structure, which form both load-bearing roof trusses and foundation-supporting wall trusses supporting the roof trusses, the roof truss and both wall trusses being joined together into a rigid circumferential whole. These circumferential nail plate grids 10 are then spaced apart at relatively even intervals in the amount required by the length of the building.

According to the invention, the two nail plate trusses forming a rigid circumferential whole are connected in parallel to each other into a rigid whole, a double nail plate grid structure. In this way, the individual bars of the lattice are reinforced in such a way as to prevent buckling of the individual bars.

Preferably, the grids are fastened to each other by means of suitable spacers, i.e. spacers of suitable size are arranged between the grids 20 at a suitable distance from each other, by means of which the grids are e.g. nailed together into a rigid whole.

A grid • · ^ is preferably used as the spacer. 25 pieces of wood, thick and wide, on chalks or rods. Their length may vary from case to case • · · so that, for example, on the bars of the truss, which are subjected to the greatest compressive stresses, two * ·; the space between adjacent rods extending all the way »· ·; : 30 spacer. Between a pair of rods subjected to less compressive forces, its length may be placed. depending on the one or more short blocks • ** \ as spacers. Especially in those pairs of rods which are subjected only to tensile stresses, no intermediate, i .: "J pieces are necessarily required.

• «· i,., ** Similarly, the lattice of both the roof section and. ·. 3 «9,987 spacers of different lengths» »· · · · ^ ♦,» i ·· * »can be used on the joists of the wall sections at suitable distances from each other in the manner and density required by the loads on the structure.

When rigidly fixing the circumferential nail plate truss structures according to the invention to the foundation, means and methods known per se can be used in the fastening. One well-established attachment is disclosed in the applicant's Finnish Utility Model Registration No. 203, which is hereby incorporated into this application.

Preferably, between the nail plate grids, i.e. in the space delimited by the spacers, a substantially horizontal steel traction element 15 extending from the edge to the edge of the nail plate grid structure is placed, e.g. a rigid steel bar tightened between the ends of the grid to reduce the horizontal support reaction and increase grid stiffness. The steel tensile element is particularly suitable for long-span truss structures, and especially for truss structures in which the walls are formed by vertical or nearly vertical parts of the truss, whereby the load on the ceiling spreads the walls more apart. In substantially arcuate or oblique-walled structures, steel ·. 25 support elements are not needed or at least they are not very necessary.

.: The rigid structure according to the invention is preferably rigidly attached to the foundations, in particular with large *. at spans, rigid fastening is necessary, but ·· .1 30 in relatively small structures, garages and similar halls, fastening to foundations can be done with traditional articulation technology.

: The rigid, circumferential nailing device according to the invention can consist of 35 parts during the manufacturing and transport stages, which are assembled as a whole only at the installation and erection site. Thus, the truss structure according to the invention has mounting extensions, supporting joint areas, of which the truss parts can be joined together, usually by nailing, screwing or bolting. In this way, nail plates are not required in these joint areas, the use of which always requires carefully controlled installation conditions, 5 so that their use on site is not possible.

The double nail plate truss structure according to the invention enables truss structures much more diverse than known nail plate trusses as well as steel trusses, larger spans with lighter structures 10 and the affordability and easy transportability and erection of the structures. Similarly, the lattice structures according to the invention are needed less frequently, even in large structures of the order of 5 meters, in which case it becomes possible to build doors between them.

The invention will now be described in detail with reference to the accompanying drawings, in which Figure 1 shows a side view of a frame structure according to the invention, Figure 2 shows a section of the frame structure of Figure 1, Figure 3 shows another section of the frame structure of Figure 1, Figure 4 shows a structure according to the invention, Figure 5 shows another Fig. 6 shows a third structural solution according to the invention, Fig. 7 shows a fourth structural solution according to the invention, / Fig. 8 shows a fifth structural solution according to the invention and Fig. 9 shows a sixth structural solution according to the invention. : cuddle.

: In the circumferential · according to the invention shown in Fig. 1. The nail plate truss 35 has vertical outer portions 9 of the wall portions and inwardly and upwardly inclined inner portions 10, which are connected to each other by a number of rods 5. 1 # 5 97987 The upper end of these braces is supported at an angle by the lower girder 11 and the upper girder 12. , which are connected to each other by a number of rods 5 between them. This forms the rigid cross-structure 5 shown in the figure, which extends from one foundation 3 to another.

Figure 2 shows a section of the roof part of the grid of Figure 1, in which the structure according to the invention is shown. Thus, the nail plate grid of Figure 1 comprises two adjacent nail plate grids consisting of the above-mentioned chords and spacer bars 10 connected to each other as a rigid whole by spacers 6 suitably positioned between and nailed to both the rods 5 and the straps 9, 10, 11 and 12. as required by forces 15.

The lower ends 13 of the nail plate trusses are, for example, rigidly fastened to the corresponding foundations 3 with bolts.

Figure 3 shows the attachment of the steel tension element 20 of Figure 1 between the ends of the nail plate grid. As shown in Fig. 3, the upper rafters 12 are connected to the outer rafters 9 by nail plates 14. There are spacers 6 at a suitable distance between the outer rafters and the upper rafters. Thus a gap corresponding to the thickness of the spacer 25 is left outside the spacers and a steel pulling element 7 is placed in this gap. is attached to support plates 15 resting on the outer surfaces of the outer rafters. Thus, the steel tension element supports the upper end of the wall-30 portions of the circumferential nail plate grid, increasing the rigidity and reducing the horizontal support reaction.

The nail plate truss structure of Fig. 1 consists of three separate industrially manufactured parts, which are only joined together at the installation site. Thus. The structure 35 has two mounting extensions 8, parts provided with rods additional to the rest of the structure, of which the parts can be joined together with sufficient strength by nailing, bolting or countering.

Figures 4 to 9 show schematic diagrams of different nail plate grid shapes that can be implemented with the structure according to the invention 5. Essential in all six structures is the double structure of the trusses supported together, as well as a rigid whole from one foundation to another.

Figures 4 and 5 and 8 and 9 show substantially 10 straight wall portions in a nail plate grid, whereby the use of a steel traction element is desirable, in wider applications 4 and 5 even necessary. In the substantially curved structure of Figure 7, depending on the dimensions and the application, a steel traction element may be necessary in some applications, but in the structure of Figure 6 it is not required.

The invention has been described above without limiting it in any way by means of examples, the various embodiments of the invention being possible within the scope of the inventive idea defined by the appended claims.
