Background of invention
-
The invention relates to a construction according to the preamble of claim 1. The invention also relates to a method for manufacturing the construction according to the preamble of claim 6. The invention further relates to using the construction according to the invention and the construction manufactured with the method according to the invention.
-
Of prior art, several different constructions are known which can be employed e.g. as climbing constructions or support constructions or for some other use.
-
A construction is described e.g. in an arrangement presented by specification
FR2837397 which depicts a construction, and in more detail a climbing construction, which consists of several laminar parts which are connected with connecting parts to each other, and of which laminar parts are thus formed box-like pieces, and which box-like pieces are then set one on the other. In the arrangement according to the specification, the box-like pieces are coated with concrete the purpose of which is to 'imitate' a rock face.

Detailed description of invention
-
Fig. 1a shows a front view of a construction according to the invention, and the construction 1, which is lattice-like, comprises several tubular and/or beam- like support pieces 6, 7, 11 which are directly or indirectly fitted in an elongated frame piece 2 (which elongated piece can be e.g. a steel pipe or a steel bar), and further the frame is fitted with a support structure 15, such as support reinforcement of steel. The construction 1 is fitted with a meshwork 10, such as a steel meshwork, such that the meshwork is fastened in a subframe 14 and/or the frame and/or the support structure 15, which subframe comprises at least one tubular and/or beam-like piece 5 being substantially elongated, and which tubular and/or beam-like pieces 5 are fitted in the support pieces 6, 7, 11 and/or the frame piece. The support structure 15 is fastened in the invention on top of the meshwork 10, but the support structure can also be fastened beneath the meshwork.
-
The purpose of the subframe, i.e. the tubular and/or beam-like pieces 5, is to enable various appearances for the construction, such as shown in Figs. 2a-2c. The tubular and/or beam-like pieces of the subframe can be of different lengths, and they can be fastened at desired points of the construction, and the tubular and/or beam-like pieces forming the subframe can be straight, curved etc.
-
In the construction according to the invention, the meshwork 10 is coated with sprayed concrete. The sprayed concrete is supplied on the surface of the meshwork either with dry or wet spraying technique.
-
The meshwork 10, the mesh size of which is 1-18 mm, is fastened in the subframe 14 and/or the frame and/or the support structure with suitable fastening pieces 16, but the meshwork can alternatively be fastened by welding or in some other suitable way. The fastening pieces can be e.g. steel nails (e.g. driven by a nail gun), screws or bolts, but the fastening pieces can also be quick-fastening pieces, such as cable ties of metal or some other material.
-
The ends of the frame piece 2 include a rotation support, such as a pivot, a shaft or a projection 13, where the frame piece can be supported in order to rotate the frame piece around its longitudinal axis. A foot part, such as a foot ledge, by means of which the construction is supported and fastened in a substantially vertical position, is designated with reference number 9. Reference number 8 designates a topmost support pipe/support bar of the construction which is fastened at the ends of the support pieces 11.
- Fig. 1b shows a top view of the construction of Fig. 1a. The support pieces in Fig. 1b are of the same length and symmetrically fitted in the frame piece 2, but the support pieces can also be of different lengths and unsymmetrically fitted in the frame piece 2. In the support pieces 11 is fastened the subframe, i.e. the tubular and/or beam-like pieces 5. The meshwork 10 is fitted on top of the subframe, i.e. the tubular and/or beam-like pieces, and the meshwork is coated with concrete (not shown in the figure). The tubular and/or beam-like pieces can be in a desired way and of desired length fastened in the support pieces 11 or the other parts of the construction, and thus they provide a desired shape for the meshwork when the meshwork is fastened in the subframe, i.e. the tubular and/or beam-like pieces.
- Figs. 2a-2c show a top view of some possible different shapes for the construction according to the invention. However, the shapes of the construction are not solely limited to the ones shown in the figure, because it is possible to form the construction of a desired shape, depending on the number and length of the tubular and beam-like pieces and on how they are fastened in the support pieces 11. The tubular and/or beam-like pieces operating as the subframe can also be e.g. of curved, angular etc. shape and their number is not limited, i.e. a desired number of them can be fitted in the support pieces 11 and at desired points of the support pieces.
- Fig. 3a shows the construction according to the invention which can be rotated in a rotating frame 12 around the longitudinal axis of the construction, because the ends of the construction include the rotating support 13 where it can be supported on the rotating frame when manufacturing the construction, when e.g. the support reinforcement is fastened in the construction being manufactured, and the meshwork, and when spraying concrete in the meshwork.
- Fig. 3b shows the spraying of concrete in the construction, i.e. the meshwork 10. The concrete spray is designated with reference number 16. The spraying of concrete on different sides of the construction 1, in the meshwork 10, is easy to perform as the construction is thus rotatable in the rotating frame. The rotating frame 12 can include a drive, such as e.g. an electric drive or a hydraulic drive, or it is possible to operate it manually e.g. by means of a hoist with which the construction is rotated when it is in the rotating frame. This is not yet shown in the figure.
- Fig. 3c shows a top view of the rotating frame.
-
The method according to the invention for manufacturing the construction 1 will be described next, with reference to Figs. 1a, 1b and 3b.
-
In the method according to the invention, a lattice-like frame is formed of several tubular and/or beam- like support pieces 6, 7 and 11 which are directly or indirectly fitted i.e. fastened in an elongated frame piece 2, which support pieces and/or the frame piece are fitted with a support structure 15, such as support reinforcement. In the frame piece and/or the support pieces is fastened a subframe 14, which subframe comprises at least one tubular and/or beam-like piece 5, and in the subframe 14 and/or the frame and/or the support structure 15 is fastened a meshwork 10, such as a steel meshwork, which meshwork is coated with concrete by spraying concrete in it as dry or wet spraying.
-
The construction according to the invention can be rotated in a rotating frame 12 around the longitudinal axis of the construction when manufacturing the construction, when e.g. the support reinforcement is fastened in the construction being manufactured, and the meshwork, and when further spraying concrete in the meshwork.
-
The meshwork is fastened in the subframe and/or the frame and/or the support structure with nails, screws or bolts, but it can also be fastened in the subframe and/or the frame and/or the support structure with quick-fastening pieces, such as e.g. cable ties made of metal or some other material. The meshwork can alternatively be fastened in the subframe and/or the frame and/or the support structure by welding.
-
It is well known by those skilled in the art that the different embodiments of the invention are not solely limited to the examples described above, and thus they can vary within the scope of the appended claims.
-
In the arrangement according to the invention, the different parts of the construction, such as the elongated frame piece or the support pieces, can each consist of one or several pieces, e.g. such that several metal profiles, such as steel bars or steel pipes, are welded or fastened in some other way, e.g. by bolts, together.
-
The construction according to the invention can also be fitted with fixed or detachable climbing holds for climbing e.g. such that the climbing holds are fastened in the concrete (sprayed in the meshwork) with bolts, screws or other fastening means. The fastening of the climbing holds can also occur e.g. such that the climbing holds are first fastened in the meshwork or at some other point, such as the support parts, in the construction, and only then the concrete is supplied on the surface of the meshwork.
