Description
Column shoe
Background of the invention
The object of the invention is a column shoe according to the preamble of claim 1.
The invention relates to column shoes which are used in lower end corners and sides of steel concrete columns or corresponding concrete element columns for securing the column to the bolts in the column base structure.
From publication FI 118186 a column shoe for securing steel concrete columns to a base is known. The column shoe comprises a baseplate provided with a bolt hole and a sideplate secured to the baseplate by welding in order to form a bolt housing. The column shoe further comprises main attachments fixed to the bolt housing for securing the column shoe and the steel concrete column together. Column shoes of this type are also known from publications FI 95164 and SE 511 606.
One problem with these known column shoes is the connection between the baseplate and the sideplate, which is a welded connection and which for this reason generates stress peaks. Welded connection also increases deformations of the connection under load and thus substantially reduces the overall rigidity of the connection of the steel concrete column implemented as a bolt connection. A further problem is caused by the rear attachment which transmits eccentric forces and which is con- nected to the structure in a separate working stage. Traditional method of implementing the rear attachment reduces the arrangement of the column shoe into a small column cross-section. Manufacturing of the rear attachment as a separate working stage also adds the production costs of the product. The carrying out of welding or other type of securing of the main attachments to the frame element may also be considered a problem of the welded structure. In all known solutions multi-stage production is required, because the end product will be formed by simple elements which are assembled together by welding.
Brief description of the invention
The aim of the invention is to solve the above problems.
The object of the invention is obtained by the column shoe according to independent claim 1.
Preferred embodiments of the invention are described in dependent claims. The invention is based on the idea that, since the bolt housing is fabricated by casting such that the bolt housing comprises a single-piece casting comprising a base- plate and a sideplate, no stress peaks are generated between the baseplate and the side-
plate. This is because as a result of casting there is created a joint of uniform quality between the baseplate and the sideplate. Moreover, the bolt housing is designed so that the connection between main attachments may be performed simply in one working stage. The bolt housing may also be formed such that the rear attachment which stabilizes the eccentric forces will be formed directly in the casting. On the other hand, the bolt housing allows to use a flexible wire as rear attachment, which wire permits to minimize the dimensions of the column or wall cross-section required by the connection part.
Advantages of the bolt housing fabricated by casting according to the inven- tion are among other things cost-effectiveness, dimensional accuracy and lesser eccentricity, which allows for connection parts of reduced weight. The inner space of the bolt housing may be made smaller by casting compared to welded structures, whereupon there is no unused space, and on the other hand a smaller size of the bolt housing is permitted. Bolt housing made by welding generally has, inside the housing, a weld between the baseplate and the sideplates, which weld takes place from the baseplate, which is needed between the nut of the bolt secured to the bolt housing and the washer of the bolt housing. This results in that a welded bolt housing will never be made as compact as a cast bolt housing.
In one solution according to the invention the bolt housing is comprised of a single-piece casting.

Detailed description of the invention
The object of the invention is a column shoe 1 for securing steel concrete columns 2, such as concrete element columns to a base 3, such as a foundation of building or corresponding load-bearing structural element. Fig. 15 shows a base 3 on which a steel concrete column 2 has been secured.
Figs. 1 to 6 show a first preferred embodiment of the column shoe 1.
The bolt housing 1 comprises a bolt housing 4, which comprises a baseplate 6, provided with a bolt hole 5, and a sideplate 7. In Figures the sideplate 7 is arcuate in shape, but alternatively the sideplate 7 may comprise rectilinear, planar portions.
The column shoe 1 further comprises main attachment units 8 fixed to the bolt housing 4 for securing the column shoe 1 and the steel concrete column 2 together.
The bolt housing 4 is fabricated by casting such that the bolt housing 4 comprises a single-piece casting 9 comprising a baseplate 6 and a sideplate 7.
Said single-piece casting 9 is preferably, but not necessarily, fabricated from cast steel or cast iron.
In Figures the bolt housing 4 consists of a single-piece casting 9. It is however evident, that the bolt housing 4 may in addition to such a single-piece casting 9 also comprise parts which are secured to such single-piece casting 9.
The bolt hole 5 of the baseplate 6 may be formed during casting. It is however evident, that the bolt hole 4 in the baseplate 6 of the bolt housing 4 may at least partly be machined after casting on the baseplate 6 of the bolt housing 4.
An elongate groove 16 may be formed by casting or at least by machining on the sideplate 7 of the bolt housing 4 for the main attachment unit 8. In Figures, two elongate grooves 16 are formed by casting on the sideplate 7 of the bolt housing 4 for the main attachment unit 8. In Figures both main attachment units 8 are secured to the elongate groove 16 by welding. It is also possible for the sideplate 7 of the bolt housing 4 to be formed by casting or at least partly by machining a hole 17 or more holes, in which the main attachment unit 8 is at least partly arranged. In case a hole is formed in the sideplate 7 of the bolt housing 4, the main attachment unit 8 may be secured to the sideplate 7 of the bolt housing 4 by pressing the bolt housing 4 into engagement with the main attachment unit 8 at the location of the hole 17, i.e. by pressing the bolt housing 4 into engagement with the main attachment unit 8. It is also pos- sible that the sideplate 7 of the bolt housing 4 has only one hole 17, which is provided with inner threads (not shown in Figures) and that there is at least one main attachment unit 8, which is provided with matching outer threads (not shown in Figures) so that the main attachment unit 8 is secured to the hole 17 by screwing the main attachment 8 to the hole 17. It is also possible that there is at least one main attachment unit 8, which is secured to the hole 17 by means of a sleeve (not shown in Figures) so that the sleeve is positioned in the hole 17 and that the main attachment unit 8 is positioned at least partly in the sleeve so that between the hole 17 and the sleeve and respectively the sleeve and the main attachment unit 8 there is formed for example a form-locked or friction-locked connection.
The bolt housing 4 of the column shoe may be provided with a top structure
19. Figs. 26 to 30 and Figs. 31 to 35 show bolt housings 4, which are provided with such top structure 19. In Figs. 26 to 30 the top structure 19 is provided with two holes 17 for the main attachment unit. It is possible that there is at least one hole 17, which is provided with inner threads (not shown in Figures) and that there is at least one main attachment unit 8, which is provided with matching outer threads (not shown in Figures) so that the main attachment unit 8 is secured to the hole 17 by screwing the main attachment 8 to the hole 17. It is possible that there is at least one main attachment unit 8, which is secured to the hole 17 by means of a sleeve (not shown in Fig-
ures) so that the sleeve is positioned in the hole 17 and that the main attachment unit 8 is positioned at least partly in the sleeve so that between the hole 17 and the sleeve and respectively the sleeve and the main attachment unit 8 there is formed for example a form-locked or friction-locked connection. In Figs. 31 to 35 two slots 20 are formed to the top structure 19 for the main attachment unit and to which slots the main attachment units 8 may be positioned such that they will subsequently be engaged by welding.
In Figures, the main attachment units 8 comprise reinforcement bars 11.
The column shoes 1 shown in Figs. 1 to 6 and Figs. 12 to 14 comprise a rear attachment unit 10 for transmitting to the steel concrete column 2 the lower horizontal force of the horizontal force couple generated by eccentric position relative to the bolt situated at the location of the main attachment units 8 and the bolt hole 5.
In Figs. 1 to 6 the rear attachment unit 10 comprises a reinforcement bar 11.
In Fig. 12 the rear attachment unit 10 comprises a plate part 12, which is se- cured to the bolt housing 4, and a reinforcement bar 11, which is secured to the plate part 12.
In Fig. 13 the rear attachment unit 10 comprises a flexible wire loop 13.
In Fig. 14 the rear attachment unit 10 comprises a flexible wire 14, to the end of which is connected a pressure sleeve 15.
At least one attachment lug 18, which protrudes from the bolt housing 4, may be formed by casting to the bolt housing of the column shoe for enhancing the fastening of the bolt housing 4 to the steel concrete column. The attachment lug 18 may also serve as stiffener or support for the bolt housing 4. Figs. 21 to 25 and Figs. 36 and 40 show bolt housings 4 to which one such attachment lug 18 is formed by casting. Figs. 16 to 20 show such bolt housing 4 on which two such attachment lugs 18 are formed by casting. The attachment lug 18 may be provided with at least one attachment hole 21 through which during assembly phase of the column shoe, a wire or a reinforcement bar may be passed in order for example to secure a plurality of column shoes together.
Figs. 7 to 11 show a first preferred embodiment of the bolt housing 4. In Figs.
7 to 11 the bolt housing 4 forms a single-piece casting. In Figs. 7 to 11 two elongate grooves 16 are formed on the sideplate 7 of the bolt housing 4, into which grooves main attachment units may be positioned so that they are engaged by welding to the elongate grooves 16.
Figs. 16 to 40 show five other preferred embodiments of the bolt housing 4 of the column shoe.
