Detailed Description
Hereinafter, some embodiments and modifications of the column shoe and the column shoe for fastening the reinforced concrete column to the base will be described in more detail.
The pole shoe comprises a bottom plate 1 with a bolt opening 2. The bootie further comprises a side wall member 3, which side wall member 3 is fastened to the bottom plate 1 for providing a bolt housing 4 of the bottom plate 1 and the side wall member 3. When the column shoe is cast into a reinforced concrete column and the reinforced concrete column is fastened to the base by means of the column shoe, a threaded rod or the like protruding from the base penetrates the bottom plate 1 in the bolt hole 2 and a nut is screwed to the threaded rod to fix the column shoe to the threaded rod.
The pole shoe further comprises a main joint 5, which main joint 5 is fastened to the side wall member 3 for fastening the pole shoe and the column of reinforced concrete to each other.
The pole shoe further comprises a back coupling device 6.
In the pole shoe, the side wall member 3 is of unitary construction comprising two flat side plate sections 7 and a connecting section 8 connecting the two side plate sections.
The pole shoe is symmetrical about an imaginary vertical centre plane a of the bolt housing 4.
In the pole shoe, the angle α between the flat side plate sections 7 is between about 40 ° and about 60 °, preferably between about 45 ° and about 50 °, such as about 48 °.
In the pole shoe, the back coupling device 6 comprises a back anchor 9, which back anchor 9 is fastened to the back surfaces 12 of each flat side plate section 7 facing away from each other. Each back anchor 9 has a fastening section 10 and a vertical section 11 extending parallel to the main joint 5, by means of which fastening section 10 the back anchor 9 is fastened by welding along the fastening section 10 to said back surface 12 of the side plate section. The back coupling device 6 is dimensioned in the following manner and the back coupling device 6 is fastened to said back surface 12 of the side plate section in the following manner: so that the vertical sections 11 of each back anchor 9 are arranged at a distance from each other.
Thanks to the arrangement of the back anchors 9 firmly fastened to said back surfaces 12 of the side plate sections by welding along the fastening sections 10, the back bonding means 6 will be firmly fastened to the flat side plate sections 7. The narrow angle α between the flat side plate sections 7 enables the use of two separate anchors. Due to the angle α between the flat side plate sections 7 the cross section of the pole shoe is small, which makes it easy to mount e.g. 4 pole shoes to a pole with a small cross section, one in each corner. Due to the narrow angle α between the flat side plate sections 7, the cross section of the pole shoe is small, which results in saving of pole shoe material, which in turn results in a reduction of material costs and a reduction of weight of the pole shoe, which in turn makes the pole shoe easy to handle. The narrow angle α between the flat side plate sections 7 also results in an increased stiffness of the bolt housing 4 of the pole shoe. This has the advantage that the side wall member 3 can be made of a thinner material to achieve the required stiffness. Thanks to the provision of the back coupling means 6 comprising two separate back anchors 9, the arrangement of the pole shoe in relation to the reinforcement structure of the reinforced concrete column is easy when the reinforced concrete column is manufactured by casting. The space required for using two separate back anchors 9 is also less and this makes it possible to make the pole shoe smaller than if a single back anchor were used, which in turn makes it possible to make the cross section of the pole where the pole shoe is to be used smaller. The use of two separate back anchors 9 in the pole shoe will result in a more even distribution of force to the pole in which the pole shoe is used than a pole shoe provided with a single back anchor.
Preferably, but not necessarily, the back anchors 9 are identical and arranged symmetrically with respect to an imaginary vertical central plane a of the bolt housing 4.
Preferably, but not necessarily, the main joint 5 comprises two main joints 5, such that one main joint 5 is fastened to the inner surfaces 13 of each flat side plate section 7 facing each other.
Preferably, but not necessarily, the main joint 5 is identical and arranged symmetrically with respect to an imaginary vertical central plane a of the bolt housing 4.
Preferably, but not necessarily, the fastening section 10 of each back anchor 9 extends perpendicularly with respect to the vertical section 11 of the back anchor 9.
Preferably, but not necessarily, the bolt openings 2 in the bottom plate 1 are arranged symmetrically with respect to an imaginary vertical center plane a of the bolt housing 4.
As shown in the drawings, in the side wall member 3, the connecting section 8 is preferably, but not necessarily, curved. The flat side plate section 7 facilitates fastening of the back anchor 9 by welding to the flat side plate section 7 and enables a more secure connection between the flat side plate section 7 and the back anchor 9, as the welded joint between the flat side plate section 7 and the back anchor 9 can be linear. Providing curved connecting sections 8 enables the side wall member 3 to be more rigid.
As shown in the figures, the fastening section 10 of each back anchor 9 preferably, but not necessarily, extends parallel to the bottom plate 1.
As shown in the drawings, preferably, but not necessarily, the imaginary vertical central plane a of the bolt housing 4 is not penetrated by any of the back anchors 9. This makes the column easy to manufacture and makes it easy to install the column shoe in a mould for casting the column.
As shown in the drawings, preferably, but not necessarily, each back anchor 9 is arranged spaced apart from an imaginary vertical central plane a of the bolt housing 4. This makes the column easy to manufacture and makes it easy to install the column shoe in a mould for casting the column.
It is obvious to a person skilled in the art that as the technology advances, the basic idea of the invention can be implemented in various ways. The invention and its embodiments are thus not limited to the examples described above but may vary within the scope of the claims.
