Description

CONNECTED PI LARI / PILE 94795

The invention relates to a composite column / pile comprising a pipe and the casting component contained therein and a casting reinforcement in which the pipe consists of separate profiles which are bound together at their edges into a closed circuit.

Today, composite columns are made of welded steel pipe, which also includes a separate reinforcement.

10 In particular, welded steel pipe incurs considerable costs, which makes the structure economically disadvantageous. The benefit of high-strength concretes is largely lost due to their fire sensitivity.

The object of the present invention is to provide a novel pillar / pile structure which makes it possible to manufacture it economically. The characteristic features of the invention are set out in the appended claim. The extension flange according to the invention has two functional functions. First of all, it also acts as an angle reinforcement. The extension flange preferably includes suitable gripping members. On the other hand, the extension flange allows the opposite edge flanges to be pulled apart from each other without the concrete mass being allowed to drain away between them. The edge flanges and the outer part of the profile are equipped with holes that allow bolt-nut installation from outside the pipe. The mounting holes on the outside of the profile also have the function of releasing water in the event of a fire. steam out of the tube. A highly advantageous column structure in terms of fire technology is obtained in such a way that a so-called inner buckle reinforcements terminated in the holes in the extension flange. These act as water vapor traps in the event of a fire, so that the crystalline water released from the concrete does not damage the structure. The invention will now be described with reference to the accompanying figure, which shows a composite column according to the invention.

The advantages of the new pile or pillar are ease of use and simplicity of construction. Figure 1 below shows the structure of the composite pillar (1). The column casting tube consists of a fourth to 40 profiles (2), each with a trough-like outer surface 2 94795 and flanges (3 and 5) turned inwards at an angle of about 45 °, from which the other flange (3) is further formed an extension flange (4) turned at an angle of about 90 °. ). Such profiles (2) can be assembled into a substantially square pile, which are fastened to each other with bolts (8). For the bolts (8), the outer surface of the profile (2) has holes (6).

Figure 1 shows an inner buckle reinforcement (17) mounted inside the profile, which is attached to the holes made in the corner reinforcements.

With thin plate thicknesses, the gutter-like outer surface stiffens the profile and then also allows a simple pull of electrical wires (13) or other piping on the outer surface of the beam.

By means of the invention, the sub-profiles bent from a simple sheet form an easily connectable pipe which acts as both a mold and a reinforcement. The inward corner turns replace the corner reinforcements and stiffen the pipe-20 kennel before casting, and form a fire-protected inner reinforcement in the composite structure.

In the event of a fire, the inner buckle reinforcement acts as a water vapor trap and the screw holes in the outer flanges act as steam-25 outlet holes in the event of a fire. These can be fitted with plastic plugs when molding. Internal reinforcements can be attached directly inside the pipe to the corner stiffeners.

The corner flanges can be provided with gripping members, knobs, 30 holes, bent strips or their edge can be rolled into a corrugation.

In the pillar / pile according to the invention, the full advantage is obtained from the high-strength concrete, because the fire situation is controlled. The escaping water vapor cools the surface profiles, so the strength of the composite structure is maintained for a long time.
