BRACKET

The invention relates to a support for fixing a building element to the side of a concrete pillar, the support comprising a support part placed on the concrete pillar and a support part attached to the building element, comprising parts projecting from the surface of the building element and a support plane to be fastened thereto.

10 Building elements, such as concrete beams or the like, are attached to the sides of concrete columns with various supports. Finnish patent 72369 discloses a building system consisting of a concrete pillar and a building element supported by a support member attached thereto. The support member is supported on a part 15 placed on the surface of the building element, and an attempt has been made to transfer the compressive stress caused by the support to the concrete by means of gripping steels 13. FI patent 81865, on the other hand, discloses the joining of two building blocks to each other using a surface-oriented support plate 7 located on the surface of the building block 20, to which a plate-shaped connecting member 9 is attached and has a support surface 7a substantially domestic to the main building anchoring member; against the direction.

The problem with using current proponents is that • · ·. *. ! as the beam or other element bends, the support reaction moves to a different • «point, and the change in stress cannot be reliably predicted. A further disadvantage is that at the points I * »30 of the supports, a high local stress moment is applied to the concrete columns, which cannot be distributed to the other structure of the concrete column in a controlled manner.

The object of the invention is to provide a support which. 35 removes the shortcomings of existing brackets. In particular, the object of the invention is to provide a '' 'support, in the use of which the support reaction is at the same point 2 100417 also when the element is bent. It is a further object of the invention to provide a support in which the moment caused by the support reaction is transferred to the rest of the structure of the concrete pillar in a controlled manner.

The object of the invention is achieved by a support which is characterized by what is stated in the claim.

In the support according to the invention, the support plane is fixed to the protruding parts of the support part at an oblique angle when viewed from the side, so that the front edge of the support plane is higher than the edge inside the element. When the support plane is at an oblique angle, i.e. inclined, with respect to the protruding parts, the support reaction does not move when the element bends to a different point. In this case, it can be prepared for when designing and manufacturing the structure.

In a preferred embodiment of the invention, protrusions extending inside the concrete column are attached to the support member to convert the moment caused by the support reaction 20 of the beam into a pair of horizontal forces or a pair of vertical forces. The protrusions extending inside the concrete column divide the torque as desired into either a pair of horizontal forces or a pair of vertical forces. In this case, the stresses on the pillar: '·' are known and can be prepared for.

: 'V 25::: The invention will now be explained in more detail with reference to the accompanying drawing, in which Figure 1 shows an application of a support according to the invention obliquely to the side and the support part being placed on a fit 30 concrete column, Figure 2 shows a another embodiment of a bracket according to the invention, viewed obliquely from the side and the support part being placed on a concrete pillar, and Fig. 3 shows a side view of the connection of a building element to the pillar using the bracket according to Fig. 2.

In the applications according to the figures, the support comprises a support part

3 100417 2 and a support part 4. The support part 2 is placed in the edge part of the concrete column 1 and comprises cavity-like supports 9. The support part 4 comprises protruding parts 5 which are of plate-like material and a support level 6.

Figures 1 and 2 do not show a building element for the sake of clarity, but Figure 3 shows the attachment of the bracket to the element. A reinforcement and support material 10 is placed in the building element 3, which is attached to the plate part 11.

This plate part is in turn fixed to a support plane 6 at an oblique angle to the edge of the element. As shown in Fig. 3, the leading edge of the support plane, i.e. the outer edge, is higher than the edge inside the element, so that the support plane is inclined inwards. The bracket-15 so 6 is attached to the protruding parts 5 protruding from the building element, of which there are two in these applications.

According to Fig. 3, the protruding parts 5 extend beyond the edge of the element and their outer parts can be inserted into the cavities 9 of the support part so that the upper parts of the protruding parts 5 rest on the outer wall of the space formed at the upper edge of the cavities. In this case, a firm fastening is achieved.

In the embodiment according to Figure 1, the support part 2 extends to the concrete; from edge 1 to edge and is a unitary piece to which the elements can be attached on both sides. Below the support part • · ···, diagonally downwardly extending projections 8 are arranged, by means of which the moment 30 caused by the support reaction of the beam is converted into a pair of vertical forces.

»· * ... In the application according to Figures 2 and 3, the support part includes its • · · *. above and below the projections 7 extending towards the center of the pillar 1, the upper ones being bent at their ends:: 35 downwards. Such protrusions provide a supportive reaction ’. torque caused by the converted horizontal force pair.
