Connecting element support foot height adjustable

The innovation relates to a connecting element, in particular for supporting wooden supports with the corresponding possibility of adjusting the height while simultaneously absorbing tensile loads (axial displacement upwards).

A number of column feet are known for connecting a wooden column to a solid foundation in an area exposed to the weather. These usually have the disadvantage that the height cannot be adjusted over a large area. There are also column feet that allow tensile loads to be absorbed, but the creation of the necessary positive connection requires appropriate drilling jigs.

There are also column feet that use the well-known metric or similar threaded rods with a continuous thread. However, these have the disadvantage that the thread must be treated with care, so that if it is damaged, the function of adjusting the height and absorbing the load from the wooden column may no longer be guaranteed. Another disadvantage of these threads is their sensitivity to dirt and their low pitch.
Furthermore, these column feet do not allow any inclination or warping of the axes.

In contrast, the innovation is based on the task of creating a column base that does not have the deficiencies outlined; in particular, the column base itself should be simple, inexpensive and easy to use or install with the highest possible security of the connection, as well as saving time, also with regard to the special conditions in rough construction site operations.

This problem is solved by the features of the main claim.

Creating the central hole in the wooden support is easy. Since the pipe section is surrounded by material on all sides, there is no risk of the wooden support splitting or anything similar.

For effective protection against axial displacement, it is proposed to proceed as claimed. The hole to be made after joining the pipe to the beam does not cause any difficulties, since the position of the pipe section is easy to determine and, on the other hand, the pipe is relatively thin-walled, as far as the mechanical strength allows.

It is particularly important, however, that the tolerances that are almost unavoidable during construction can be compensated for by means of the thread, and this can be done according to claims 4 and 5 almost over the entire length of the threaded rod 5 and very quickly due to the large pitch.

According to claim 6, the thread is largely insensitive to dirt or damage. Likewise, the coarse thread according to claim 7 allows a certain inclination and twist, so that the abutment plate attached to the concrete does not have to be aligned exactly horizontally.

Furthermore, the components can be assembled separately according to claim 8. This is very advantageous if the abutment plate 10 with welded threaded rod 5 is first cast into the foundation 9.

The drawing illustrates the innovation, for example;

against axial displacement

According to Fig. 1, a pipe section 2 is located in the hole 12 of a wooden support 7, which rests on an abutment plate 3 that is firmly connected to the pipe section. The abutment plate 3 is in turn firmly connected to a threaded nut 4. The threaded rod 5 is firmly connected to another abutment plate 6. Since tolerances must almost certainly be compensated for during construction, this height compensation is carried out by turning the firmly connected parts 2, 3, 4 relative to the firmly connected parts 5, 6. The abutment plate 6 is usually attached to the foundation 9 with dowels and screws 8. It is advisable to only create the positive connection against axial displacement upwards at the end, as shown in Fig. 3.

Fig. 2 shows the possibility of anchoring the abutment plate 10 together with the continuous threaded rod 5 in a prepared hole or recess 11 of a foundation 9 by subsequently gluing or pouring it in. The height adjustment is carried out as shown in the description in Fig. 1.

Fig. 3 shows the positive connection against axial displacement upwards. Here, after joining the connecting element 2, 3, 4 with the wooden support 7, a hole 13 is made across the wooden support 7 together with the thin-walled tube, and a pin 1 is inserted into this hole 13 in a self-locking manner.

Connecting element according to claim 1, characterized in that the securing against axial upward displacement of the parts to be connected on the pipe section (2) is formed by pins (1) which are self-lockingly inserted into bores (12, 13) made after the parts have been joined together and which cross the axis of the pipe section (2). 3. Connecting element according to claim 1, characterized in that the distance between wooden supports (7) and foundation (9) can be changed almost arbitrarily by turning the abutment plate (3) with threaded nut (4) and pipe section (2). 4. Connecting element according to claim 1, characterized in that the range of change for the distance between the wooden support (7) and the foundation (9) corresponds to the length of the threaded rod (5). 5. Connecting element according to claim 1, characterized in that a threaded rod (5) with a large pitch is used. 6. Connecting element according to claims 1 and 4, characterized in that a coarse thread (5) is used. 7. Connecting element according to claims 1, 4 and 5, characterized in that the central axes of the two connected components (2, 3, 4 and 5, 6 or 10) can be inclined or warped relative to one another within a certain range. 8.
