Definitions

  • the invention relates to a tool for introducing fine concrete into wall joints.
  • part of the masonry is up to about one Meters broken out and replaced with new masonry.
  • the problem here is how, regardless of whether the masonry is bricked or made of concrete, the fine concrete is to be compacted in a joint above the new masonry and below the old masonry to be supported. So far, this has been done by hand with fists and logs. This process is very labor intensive. Nevertheless, the compaction effect is uncertain. If sufficient compaction is not achieved, the masonry to be supported settles and cracks develop.
  • the invention has therefore set itself the task of providing a tool with the help of which a safe compression of the masonry can be achieved, which is easy to use and which remains comparatively light.
  • the invention is based on a tool for introducing fine concrete into wall joints and suggests that the tool has an elongated active surface with a slightly smaller width than the joint height, and a device for releasably connecting the tool with a motor-driven hammer, the direction of impact of the hammer is perpendicular to the effective surface.
  • the weight of the tool itself remains comparatively low, and nevertheless effective work is possible.
  • the fine concrete in which an excessive amount of water is to be avoided, is introduced into the wall joints and compacted to the maximum with the help of the active surface.
  • the use of fine concrete with as little water as possible allows compaction and prevents the mass from escaping.
  • the volume loss during setting is also reduced, so that the risk of occurrence of set cracks is low. Due to the slightly smaller width of the effective area than the height of the wall joint, the tool can be easily inserted into the wall joint, and there is enough leeway when working.
  • the active surface is essentially flat.
  • the active surface is arched like a fillet.
  • the fillet-like curvature produces a particularly good compression effect. This shape also allows the tool to be held in the middle of the joint, making work much easier.
  • the connecting device is a drill pipe of the motor hammer records.
  • Such a drill pipe allows the use of commercially available motor hammers. So there is no need for additional equipment.
  • the length of the drill pipe is adjusted to the depth of the joint to be machined.
  • a placement shoe with a larger width and / or length is pushed onto the active surface.
  • Such a placement shoe can be used, for example, to counteract wear on the tool, or to increase the effective area. Increasing the effective area is particularly desirable if higher wall joints are to be processed. As a rule, joints with a height of about eight centimeters are provided.
  • the tool is designed as a drop forging.
  • This embodiment is particularly durable, can cope with large loads and is low in wear.
  • an elongated plate carries the active surface on the front and the connecting device on the rear, as well as struts between the connecting device and the outer regions of the plate.
  • This shape can be performed very well in one piece as a drop forging, and is also relatively light.
  • the tool has rounded transitions between the plate, the connecting device and the preferably triangular struts.
  • the tool 1 consists essentially of the elongated plate 9, the struts 10 and the connecting device 4th
  • the plate 9 has an active surface 2 with a fillet-like curvature on its underside. On its upper side, the plate 9 is connected to the connecting device 4 by means of the struts 10.
  • the struts 10 are essentially triangular and carry in their center the connecting device 4, which receives the drill rod 6 of a motor hammer 5, which is shown in FIG. 3, in a hardened opening.
  • the drill pipe 6 can easily be replaced without special tools.
  • the length of the plate 9 is approximately 30 cm, its width is approximately 6 cm.
  • the width is slightly less than the joint height 3 of the joint 8, which is approximately 8 cm.
  • the depth of the joint 8, i.e. the wall thickness, can be up to one meter or even more.
  • Fig. 3 it can be seen how the fine concrete 11 is compacted in the joint 8 with the help of the active surface 2. If the joint is still relatively deep, a particularly long drill pipe 6 is used. Depending on the decrease in the joint depth in the course of the process, the drill pipe 6 is replaced by a shorter one.
  • the joint 8 is, for example, in masonry, the lower area of which is to be renewed piece by piece. An approximately one meter wide piece is removed from the masonry and replaced with new masonry 12. Above the new masonry 12, the joint 8 remains, which is closed at one end by a formwork board 7, which is fixed in the usual way. Now a sufficient layer of fine concrete 11 is first introduced and this layer is compacted by moving the motor-driven tool 1 back and forth. Subsequently, fine concrete is added and the process continues until the entire joint 8 is filled with the compacted fine concrete.
  • the new masonry 12 can contain an insulating layer in the usual way, but this is not shown in detail and which can also be arranged in the joint under the fine concrete 11, for example.
  • the invention can also be implemented with a tool with a flat active surface.
  • a curved active surface as shown in the drawings, has the advantage that, when compacting, the fine concrete 11 introduced tends to dodge less, and that it is also easier to hold the tool 1 approximately in the middle of the joint.
  • the tool according to the invention is used to compact fine concrete in horizontal wall joints. It is clear that the tool can also be used when the joint has an inclined course or when it comes to vertical joints.
