DETAILED DESCRIPTION OF THE INVENTION

[0049] The invention is presented in the embodiments:

Embodiment 1

[0050] Anchoring device design

[0051] The anchoring device according to the invention, intended for shuttering walls is shown in FIG. 1. It contains a body 1 equipped with an arm 11 ended with an upper tab 12 ended with a cone intended for mounting the device in the structural opening of the shuttering wall (FIG. 2), the moving closing part mounted in the body and pressed to the closed position in the rest position (FIG. 3), the lock 3 (FIG. 4) and the fastener 4, fixing at least one connecting part 5 (FIG. 5). As indicated in FIG. 2, body 1 has a rectangular shape and is equipped with an arm 11 terminated with an upper tab 12 ended with a cone. The body 1 has a through hole for use as a hand grip. Wherein arm 11 of body 1 may be of different lengths depending on the dimensions of the shoring. Similarly, the dimensions (i.e. length and thickness) of the top 12 of the body 1 are adapted to the dimensions of the shoring.

[0052] In this embodiment, the fastener 4 is a steel fastening plate, but metal sheet, composite sheet, or aluminum can also be used. Whereas a connecting piece 5 is a steel carabiner.

[0053] However, in this embodiment, the aforementioned fixing plate is equipped with two lugs for attaching the connecting piece 5 (FIG. 5, FIG. 6). Wherein, in this embodiment, slider 2, fastener 4 and slider lock 3 are connected to the body 1 by means of conical mounting screws 10. A riveted connection can also be used.

[0054] The device is characterized in that the closing part is a slider 2 with cutout 6 on one of its lateral surfaces, which matches the slider lock 3 in the open position of the device, with through pockets 7 and a bottom tongue 13. However, the lower tab 13 of slider 2 forms together with the arm 11 and the upper tab 12 of body 1 a tong closure assembly, in which the upper tab 12 is used to anchor the device in the shuttering opening, and the lower tab in the closed position of the device is a locking part that jams the device (FIG. 1, FIG. 3, FIG. 6). Moreover, as shown in FIG. 3, slider 2 is C-shaped and its internal curvature matches the shape of the through hole of body 1 designed for the user's grip.

[0055] In addition, the device contains a set of springs forming an automatic locking of the device which prevents uncontrolled opening of the device during use. Wherein, one spring 8a, which pushes the slider 3 downwards by default, is located inside the body 1 directly above the slider 3 lock and is secured from above by a grub screw 9 (FIG. 9), which prevents it from falling out. Whereas three compression springs 8b, 8c and 8d are located inside the body 1 in the through pockets 7 of slider 2 (FIG. 6).

Embodiment 2

[0056] Anchoring device according to embodiment 1, except that its body 1 is composed of a two-sided side part 14 and an upper part 15 (FIG. 12).

Embodiment 3

[0057] Anchoring device according to embodiment 1, except that its body 1 is composed of two side parts 16 and 17 and an upper part 15 (FIG. 13). Wherein, preferably, the upper tab 12 is fixed to the top part 15 of body 1 by means of a fastening bolt 18 (FIG. 14).

Embodiment 4

[0058] The mode of operation of the device according to any of the previous embodiments from 1 to 3

[0059] If you want to place the device according to the invention on a shuttering wall, you must open its movable slider 2 to the maximum. However, in order to do this, it is necessary to release lock 3 by moving it with the thumb of either hand upwards, overcoming the resistance of spring 8a in body 1, wherein the spring is secured against falling out by means of a grub screw 9. Moving the lock of slider control 3 until its topmost position (slider control lock is in horizontal position) will allow slider control 2, which has a special indentation 6 on one of its side surfaces, to move backwards (i.e. in the direction opposite to the position of the body's arm 11) in a horizontal direction, moving the tongue of the lower 13 slider control 2 away from the tongue of the upper 12 of body 1, resulting in the device taking an open position. FIG. 7 shows the direction of force application (arrow) in order to move the lock 3. However, the movement of lock 3 does not require much force. Whereas FIG. 3 8 shows the direction of force application to move slider 2. Movement of the slider 2 relative the body 1 shown in FIG. 8 enables the device to be mounted in the structural opening of the shuttering wall. Wherein the top tab of body 1 is placed in the opening of the shuttering wall.

[0060] The automatic lock of the device in the form of a set of springs 8a, 8b, 8c and 8d prevents the device from opening when in use. If no action is taken by the user and the moving parts are in the free space, the device automatically moves to the closed position (as in FIG. 6A). Only when both actions have been performed consciously (raising the lock of the slider 3 and shifting the slider 2 backwards) will it be possible to unlock the device (as in FIG. 6B) and e.g. its insertion/removal from the shuttering wall, as shown in FIG. 10 and FIG. 11.

Embodiment 5

[0061] Strength Analysis of the Device

[0062] The main strength calculations for sensitive components and anchor device parts according to the invention were carried out using the Finite Element Method (FEM) using SolidWorks Simulation 2018 software.

[0063] FEM is an advanced method of solving systems of differential equations, based on the division of a domain (the examined component) into finite elements for which the solution is approximated by specific functions, and performing actual calculations only for the nodes of this division.

[0064] The results obtained with the Simulation design analysis software provide an approximation of the stress/strain values, etc. that can be expected during the use of the equipment.

[0065] In this embodiment, the FEM simulation was performed under a load of 15 kN, i.e. the value required by the PN-EN795 standard.

[0066] The results of the FEM simulation show the correctness of the designed device according to the invention. The device according to the invention meets the PN-EN795 standard.
