Description
SPECIFICATION
Construction system
The present invention is concerned with a construction system which consists of concrete columns and of construction elements carried by means of carrier members attached to the side face of the concrete column, whereby the carrier member comprises a vertical fastening part supported against the side face of the column and a horizontal carrier part attached to the fastening part at a distance from its lower edge.
As a rule, beams of reinforced concrete are supported on columns of reinforced concrete by means of concrete brackets. A steel bracket has been used if it has been necessary to correct erroneous plans or in connection with modification work. In such a case, the steel bracket has been attached to the column by means of percussion or wedge anchors and bolts. Most extensive use of the steel bracket has occurred for supporting walls panels on columns. If a steel plate has been fixed to the column at the casting stage for the bracket, the bracket has been attached to the said steel plate by welding or by means of bolts.
The object of the present invention is to provide a simpler mode of fastening a steel bracket to a concrete column. The construction system in accordance with the invention is characterized in that the rear edge of the carrier part of the carrying member, to be fitted towards the concrete column, is provided with a hook part projecting downwards and towards the concrete column and that a side face of the concrete column is provided with a recess extending downwards behind the upper edge of a support part attached to the said side face of the column, the hook part of the said carrier member being fitted into the said recess so that it is supported against the upper edge of the support part.
In the system in accordance with the invention, the joint of the bracket with the column is based on a hooking between the steel bracket and the steel plate provided in the column. In the joint, no welding is required at all. Even the bolt fastening is necessary only for the purpose that the steel bracket should stay in its position during the transportation and installation of the column. In the solution of the present invention, tensile and compression strains act upon the steel plate installed in the column in connection with the casting.
The compression strain can be transferred to the concrete by shaping the bottom edge of the steel plate placed in the column chamfered.
The invention and its details will be described in more detail in the following with reference to the attached drawings, wherein
Figure 1 is a side view of the construction system in accordance with the invention, wherein the beam is supported on the column by means of a bracket,
Figure 2 is a side view, as a vertical section, of one embodiment of the joint used in the invention,
Figure 2a shows a detail of the modification of the joint shown in Fig. 2a,
Figure 3 shows a second alternative embodiment of the joint used in the invention,
Figure 3a shows a modification of Fig. 3, and
Figure 4 shows a third alternative embodiment of the joint used in the invention.
In Fig. 1, a beam 2 supported on a column 1 is shown. The carrier member consists of a bracket 3, which is attached to the column. In the bottom face of the end of the beam, there is a recess 4, into which the bracket fits.
In Figs. 2 to 4, the joint is shown on a larger scale while using different brackets.
The steel bracket 3 shown in Fig. 2 consists of a vertical fastening plate 5, of a horizontal carrier plate 6 fitted at the top edge of the fastening plate, and of a triangular support plate 7 fitted underneath the carrier plate 6 in the angle between the fastening plate 5 and the carrier plate 6. A rearwards and downwards projecting hook portion 8 is connected with the rear edge of the support plate fitted towards the column. The hook portion may be provided over the entire length of the rear edge or on a part of its length only. The lower edge of the fastening plate 5 is provided with a hole for the bolt 9, and the carrier plate 6 is provided with a hole for the bolt 1 0.
At the casting stage, a support plate 11 has been fixed to the column 1, the fastening plate 5 of the bracket being fitted against the said support plate. The top edge of the support plate 11 is chamfered rearwards and downwards so that it corresponds to the chamfering of the hook portion 8 of the bracket. At the casting stage, a recess 1 2 has been formed above the support plate, into which said recess the hook portion 8 of the bracket fits.
In order to transfer the compression strain resulting from the support to the concrete, bond steels 1 3 have been welded onto the rear side of the support plate 11. which said bond steels are made of round bar or profile bar. The upper bond steel 1 3 is fitted in a hole drilled into the plate 11 and fixed by welding to the front face of the plate. The bond steel 1 3 may also be attached to the plate 11 by welding it exclusively onto the rear face of the plate. Moreover, the bottom edge of the support plate 11 is chamfered in such a way that it is approximately perpendicular to the force resultant directed by the bracket at the support plate 11. whereby the load can be directed at the column efficiently.
The most advantageous angle of the chamfering depends on the ratio of the height of the bracket to the dimension of the carrier plate 6 in the direction of the column.
In order to improve the adhesion between the support plate 11 and the concrete, the area has been increased by welding one or several round or angular steel bars 1 4 parallel to the plate onto the rear face of the support plate. The lower edge of the support plate 11 is provided with a threaded hole for the bolt 9.
At the casting stage, a support plate 1 5 has been attached to the bottom edge of the end of the beam 2, which said support plate 1 5 is provided with a threaded hole for the bolt 1 0.
At the end of the beam, a vertical plate 1 6 has been attached to the end of the support plate 1 5 by welding. At the support plate 15, it is possible to use round or angular steel bars 1 7 welded onto the top face of the support plate 1 5 in order to improve the adhesion.
The bracket 3 is attached to the column 1 in a simple way by inserting the hook portion 8 into the recess 1 2 behind the support plate
11 and by fastening the bolt 9. The recess 1 2 can be concreted. The beam 2 is supported on the bracket and fixed by means of the bolt
10.
Fig. 3 shows an alternative embodiment of the bracket, whereby the hook portion 8 has been formed by welding a vertical plate onto the rear edge of the carrier plate 6. Thereby the top face of the support plate 11 is horizontal, and the recess 1 2 extends to behind the rear face of the support plate 11.
Fig. 3a shows an alternative embodiment in which the hook portion 8 is formed at the end of the support plate 6 by forming a groove 1 7 into the support plate. The width of the groove thereby corresponds to the thickness of the support plate 11.
Fig. 4 shows an embodiment in which the hook portion 8 of the bracket consists of a both horizontal and slanting part. The top face of the support plate 11 is shaped accordingly.
Other variations are also possible. The bracket may have several support plates 7 side by side. The numbers and locations of the fastening bolts 9 and 10 may vary. Besides underneath the beam, the bracket may also be fitted in a recess placed higher in the end of the beam. The bracket may also be used for supporting wall panels and, for example, ribbed slabs.
