Abstract

The invention relates to mechanical engineering, namely to means for anchoring. The purpose of the invention is to simplify the design and increase the load capacity. The dowel contains the sleeve 1 with longitudinal grooves 6. In the slots placed anchor elements 3 in the form of torus segments. In the axial channel 4 of the sleeve, a spacer rod 2 is installed. The distance rod, moving forward inside the sleeve, pushes the torus segments. The segments with their pointed ends cut into the walls of the hole of the base part. All parts of the dowel are simple in configuration and in manufacture, they are made in the form of bodies of rotation. Both of the pointed ends of each torus segment cut into the walls of the hole of the base part, which contributes to an increase in the load capacity of the dowel. 6 Il.

The invention relates to mechanical engineering, to means for anchoring.
The purpose of the invention is to simplify the design and increase the load capacity.
Fig, 1 shows a dowel; in fig. 2 - the same at the final moment of installation; in fig. 3 - connection with dowel; in fig. 4 - section A-A in FIG. 1; in fig. 5 is a section BB in FIG. 3; in fig. 6 - scan sleeve dowel.
The dowel has a sleeve 1, a spreader bar 2 and several anchor elements 3, the sleeve 1 is made with a through axial channel 4, threading 5 at one end and longitudinal grooves 6 at the other end. The expansion rod 2 is made in the form of a cylinder with a pointed tip 7 and is placed in the axial channel 4 of the sleeve from the side of the threaded thread 5 with a pointed tip towards the longitudinal grooves 6. The anchor elements 3 are placed in the longitudinal grooves of the sleeve and made in the form of torus segments with pointed ends 8, while the end walls 9 of the longitudinal grooves of the sleeve are made radial in magnitude of the radius of the torus segments, which are placed in the slots with an emphasis on the end walls. The anchor elements in the initial position are placed in the slots of the sleeve flush with its outer surface.
The dowel is mounted as follows.
In the base part to which the structural member is to be attached, an opening 10 with a diameter equal to the outer diameter of the sleeve 1 is made to a depth slightly exceeding the length of the sleeve 1. Torsal segments 3 are inserted into the grooves of sleeve 1, as shown in FIG. . 1 and 4,

and fix them with a sticky pasty substance, such as clay. A sleeve with torus segments is inserted into the hole 10 and an expansion rod 2 is inserted into the sleeve (Fig. 1).
Then the expansion rod is pressed forward until it stops, as shown in FIG. 2. The rod, the entrance between the torus segments, pushes the torus segments and, straightening them, presses the ends of the torus segments into the wall of the hole of the base part (Fig. 2). After that, the fastening bolt 11 is screwed into the thread of the base part attachable structural member (Fig. 3).
The proposed dowel is easy to manufacture and install, as it consists of simple parts such as rotation bodies. Since both pointed ends of the anchor element are involved in the work, the load capacity of the dowel increases.

Claims (1)

  1. Claims of the invention A dowel containing a sleeve, a spreader bar and anchor elements, the sleeve being threaded at one end and longitudinal grooves limited by end walls, at the other end, the anchor elements are flush with the external surface of the sleeve, and expansion the rod is mounted in the sleeve with the possibility of interaction with the anchor elements, characterized in that, in order to simplify the design and increase the load capacity, the anchor elements are placed in longitudinal The sleeve hubs with emphasis in their end walls and are made in the form of end segments with pointed ends, and the surfaces of the end walls of the longitudinal grooves of the sleeve are radially outlined.
