DE2737660A1 - Concrete component holding channel on sheet piling - is welded on piling top for steel reinforced component anchored by welding - Google Patents

Abstract

The connector is factory prepared in works and can be installed on building site without expensive formwork, reinforcement and concreting operations. On the head of the sheet piling wall (2) is welded an upwards open channel profile. The reinforced concrete prefabricated part (1) is inserted by its lower edge into this channel and anchored. The prefabricated concrete part has integral steel plates which are welded to channel profile. Alternatively an anchoring bolt can be placed through concrete component for holding it in the channel.

Description

Connection of a precast stable concrete part with a sheet pile wall

The invention relates to a connection between a precast reinforced concrete part and the head of a sheet pile wall.

It is a connection between a precast reinforced concrete part and a Known sheet pile head in which the precast reinforced concrete part has an in-situ concrete seal is connected to the sheet pile head. With this in-situ concrete seal, the elaborate Formwork, reinforcement and concreting work on the construction site is required, but is possible the advantages of sheet piling and prefabricated reinforced concrete construction, modern prefabricated construction methods are partially lost.

The invention is therefore based on the object of a connection to create between a precast reinforced concrete part and a sheet pile head, the greatest possible extent at the factory and without time-consuming formwork, reinforcement and concreting work on the Construction site can be produced.

According to the invention the object is achieved in such a way that on the At the top of the sheet pile wall, a profile that is open at the top is welded on in sections is, in which a precast reinforced concrete part with the foot side, aullen concreted and to the Reinforcement is inserted and anchored in the steel plates welded onto the precast reinforced concrete is. The steel plates welded to the reinforcement in the precast reinforced concrete part can be used be hidden with the profile. In order to also have this tail-work on the construction site To avoid this, the base of the precast reinforced concrete part is screwed to the profile.

Appropriately, the profile is a U-iron or double T-beam, also one or both of the upwardly facing flanges of the U-iron or double-T-beam are inclined inwards to z. B. Tolerances of the width of the foot of the precast reinforced concrete part to be able to calibrate.

To z. B. the insertion of the precast reinforced concrete part in the on denl Sheet pile head arranged profile to facilitate and a way to align To create the precast reinforced concrete part in the vertical, it is advantageous that the steel plates set in the precast reinforced concrete element at the foot are arranged in a wedge shape are.

Another possibility for aligning the precast reinforced concrete part To create in the vertical, the profile is a concave bent sheet metal, whereby in the precast reinforced concrete part at the base only a correspondingly convex steel plate concreted in is provided.

The advantages of the connection between a precast reinforced concrete element unc! the head of a sheet pile according to the invention are particularly in the extensive factory machining and manufacturing, which means that apart from welding or Screwing work no further work is necessary on the construction site. aside from that the advantages of modern prefabricated construction are retained.

In the drawing, the invention is illustrated using exemplary embodiments explained in more detail. They show: FIG. 1 a connection in section, FIG. 2 another Connection in section, FIG. 3 another connection in section, FIG. 4 another Connection in section, FIG. 5 shows a further connection in section.

As can be seen from FIGS. 1 to 4, there is a connection between a precast reinforced concrete part 1 and the head of a sheet pile wall 2 from an upside down the sheet pile wall 2 arranged profile, such. B. a U-iron 3 or double T-beam 4 (Fig. 1, right side), which is open at the top and welded to the head of the sheet pile wall 2 is, and two eyes on the foot in the upwardly open profile 3, 4 inserted Precast reinforced concrete part 1 concreted in and attached to the reinforcement 5 in the precast reinforced concrete part 1 welded steel plates 6, which are welded to the profile 3, 4 (Fig: 1, 3 and 4) or screw bolts 7 (Fig. 2) composite are, where the screw bolts 7 horizontally through the flanges 8 and precast reinforced concrete part 1 are guided with the steel plates 6.

To compensate for width tolerances of the foot of the precast reinforced concrete part 1 to be able to, an upwardly pointing flange 8 of the U-iron 3 or double T-beam 4 be inclined inwards (Fig. 3).

In an embodiment not shown, both flanges can be inclined inward.

To z. B. threading the foot of the precast reinforced concrete part i in to facilitate the U-iron 3 and a possibility to align the precast reinforced concrete part To create in the vertical, the steel plates 6 are arranged in a wedge shape (Fig. 4).

A special embodiment is shown in FIG. 5. Another possibility To create the vertical alignment of the precast reinforced concrete part 1 is that on the head of the sheet pile wall 2 welded profile a concave bent sheet metal 9, that with a correspondingly convex curved steel plate 10 in the foot of the precast reinforced concrete part 1 is welded, the steel plate 10 also being attached to the reinforcement 5 in the precast reinforced concrete part 1 is welded on.

To produce a connection according to the invention between the precast reinforced concrete part 1 and the head of the sheet pile wall 2, the sheet pile wall 2 is already made into panels of at the factory contracted several meters wide and with the selected profile 3, 4 or 9 provided. These finished sheet piling panels are then used on site Rammed in or vibrated in as a large surface element. Then the precast reinforced concrete part 1, which is also manufactured at the factory with the steel plates 6, 10, into the Profile inserted and only with this by welding or screw bolts 7 anchored.

The seal of the connection is made by the continuous weld seams guaranteed or with the screw connection by not shown, pressed, permanently plastic putty or a similar material.
