Description

The invention relates to scaffolds for installing and / or moving a work platform.

The scaffolds have a device for installing and / or moving the platform.

The mechanism of the working platform has a stop serving as a support for the entire device and connected by means of the first fastening to the working platform.

By means of the first fastening, the platform in the area of the first side can be supported by a support or a wall.

The platform using the first mount is connected with the first vertical rack, located essentially at right angles to the transverse beam of the platform.

On the second side of the working platform, located opposite the first side, the working platform has a second mount, which creates support for the working platform.

The second mount is connected to the jib. One end of the jib is rigidly and / or movably connected to the working platform, and the other end is connected to the first vertical stand.

At the working site parallel to the first rack and at some distance from it, at least one more vertical rack can be located that serves as a support for one or more crossbars.

Publication FR 2641018 discloses a mounting device for elevator shafts. The device is attached to the door sill and has two parallel beams resting on the opposite wall. In addition, a supporting staircase construction is provided, which serves as an entrance to a horizontal work platform. The beams are made in the form of telescopic rods with locking pins and are directed at an angle of 25 ° to the horizontal plane. This mounting device consists of many parts and has a very complex structure that does not allow for simple and quick installation.

Work scaffolds are also known having the following features (DE 19928574 C2). Working platforms have a device for installing and (or) moving the working platform. This device is designed to move the work platform and is equipped with a mount (support part). The mount serves as a support for the movable work platform. For this, the mount has a device with which the working platform on one side can rest on a support or wall. In addition, on the opposite side, the work platform has a second device, which can also be supported by a support part on a support or wall. On the opposite side, the mount has a safety device for the working platform, consisting of a locking device and a beam as a supporting device, as well as a second supporting part adjacent to the wall. The locking device is made in the form of a part, one end of which is movably connected to the working platform, and the second end is with the beam. To create support for the working platform, it is necessary that at least two side walls are located opposite each other in the shaft.

In the publications DE 803 075 C and WO 00/70169 A, working platforms are disclosed with a stand located motionless relative to the doorway. A rotatable crossbeam rests on a stand and serves as a support for the work site. The beam from the side opposite the transverse strut is fixed with a rod attached to the strut above the transverse beam. The rod is made with the possibility of bending at an angle to provide the ability to fold and unfold the work platform.

The basis of the present invention is the task of creating working scaffolds of a simple design for elevator shafts and other shafts with the possibility of installation in a short time by one person in the area of a doorway or hole in the wall.

In the invention, this problem is solved due to the fact that the transverse beam of the working platform and the vertical strut connected by means of the jib are supported by the first fastening and are made to rotate around a common bolt.

Due to the appropriate design and location, the working scaffolds can be easily fixed on one vertical wall with a hole, the presence of another wall opposite the doorway or hole in the wall is not required. Scaffolds with a vertical stand are placed in a hole in the wall, the lower part of the vertical stand is supported on the floor or its covering element, and the upper part is turned and leaned against the inside of the supporting wall.

From the point of view of simplifying installation, it is convenient that the transverse beam and the rack are inserted into the first mount and each of these parts is fixed with a bolt.

The advantage of this design also lies in the fact that the working platform is formed by a transverse beam and a base plate lying on it, and the transverse beam is connected to the jib via a second fastening.

With regard to fitting to the dimensions of the shaft, it is convenient that the jib is movably connected to the second fastener by means of a swivel joint.

It is convenient that the first vertical strut is connected to the second vertical strut by means of three essentially horizontal rungs.

From the point of view of flexibility of use, it is convenient that a second working platform with a base plate, connected by a transverse beam to the first and second racks, is provided above the working platform.

It is also convenient that a vertical post and a vertically oriented rear post are connected to the second working platform, the first being attached to the transverse beam, and the rear post is inserted into the second vertical post.

It is particularly convenient that the vertical and rear racks are connected by means of three essentially horizontal crossbars.

An additional convenience is that a hole is made in the working platform for the passage and installation of an access ladder.

The advantages of the design also include the fact that the first vertical stand serves as a support for the entire working platform.

Additional features are provided by an improved design in which the emphasis of the working platform is made in the form of a grip and / or a locking part.

Further, the advantages of the design include the fact that the above emphasis is made in the form of an angular beam resting on the corner of a wall or door threshold. Thanks to the use of a corner beam, it is enough to lean the first vertical stand on the corner of the base and clamp it, while the base takes on the main load created by the entire working platform, and the upper part of the first vertical stand is only a tensile load from the side of the working platform.

In addition, the advantage of this design is that the first mount has a vertical support element for fixing with a grip of the first vertical strut and / or a horizontal second support element for creating support for a horizontal transverse beam connected to the base plate, as well as a U-shaped support Element - to create support for vertical and horizontal support elements.

Thanks to the use of horizontal support elements on the working platform, it is easy to mount side elements, lattice fasteners or even additional struts that take load from the side of the working platform and facilitate movement along the height within the device. In the given construction example, only the right part of the scaffolds is shown. Working platforms consist of two identical or identical supporting nodes, between which a work platform or a base plate is hung or fixed. On the side, the base plate or the working platform is fenced with restrictive elements made in the form of crossbars.

Finally, according to one preferred embodiment of the invention, at least the horizontal support element and the vertical support element form a single structural unit.

Of particular importance in this case is that it is possible to rigidly connect the U-shaped support element with a stop made in the form of an angular beam.

According to the present invention, it is preferable that the jib is connected to the first vertical post by means of a top mount on the top of the post.

Further, the advantages of the construction include the fact that at least one connecting link is provided on the mounts and / or uprights, which serves as a support for the horizontal and almost horizontal slopes of the other rungs and / or base plates.

An additional advantage lies in the fact that the connecting links are made with the possibility of installation on vertical racks in different places with fastening to the racks using locking elements (bolts).

Further, the advantages of this construction according to the present invention include the fact that the supporting elements are partially made in the form of tubular elements, and partially in the form of angular, L-shaped or U-shaped elements.

In addition, the advantage of this design is that the supporting elements are made with the possibility of articulation between themselves.

Finally, the width and / or length of the platform or base plate allows them to rotate in the doorway.

Additional advantages and features of the invention are disclosed in the claims and the following description and are shown in the drawings.

It is possible to make several adjacent holes in the sides of the U-shaped support element 12.1 and / or in the transverse beam 16, allowing the transverse beam 16 to be moved along the stop 4 in the horizontal direction to adjust it depending on conditions, for example, the width of the shaft between walls 10.1 and 10.2, as shown in figa and 1b.

Located on the side of the transverse beam 16, the vertical support member 12.3 can support the lower end of the first vertical post 14. The first vertical post 14 can also be fixed using the aforementioned bolt 23. The first vertical post 14 can be made in the form of a simple pipe of rectangular cross section or telescopic pipes so that the length of the rack 14 can be changed and adjusted according to various operating conditions.

As mentioned above, the first fastener 12 is rigidly or by means of a threaded plug-in connection (not shown in the drawing) connected to the corner beam 4. In Fig. 4, only the right fastener 12 is shown. However, for the working platform 2, at least two identical first fasteners 12 located at some distance from each other in the direction perpendicular to the plane of the drawing, with a corresponding transverse beam 16 for each fastener. The base plate 15, clearly shown in figa and 1b, lies on two transverse beams 16 located at some distance from each other. The plate can be attached to the specified beams. The first fixture 12, which is located behind in the direction perpendicular to the plane of the drawing, as well as the corresponding transverse beam 16 are not shown in the drawing. The base plate 15 forms a working platform 2, providing the possibility of free movement on it.

The stop 4 is fixed on the first side 6a of the work platform 2. On the opposite side 6b opposite the stop 4 of the work platform 2 there is a second fastener 9. This fastener is shown in more detail in FIGS. 3 and 4. The second fastener 9 is used for rigid or swivel attachment to it one end of the jib 11 using a bolt or swivel 20, the other end of the jib 11, also using a swivel or bolt 21, is connected to another mount 3 located above. According to FIGS. 2 and 4, the upper mount 3 is rigidly connected to the lane howling vertical rack 14 with the ability to move in height.

As shown in FIGS. 3 and 4, the second fastener 9 consists of a vertical support element 26 and a horizontal support element 17, which can also be made in the form of pipes of rectangular cross-section. A second vertical post 33 is supported on a support member 26, and a horizontal transverse beam 16 is supported on a support member 17. The cross-member 16 and the second vertical post 33 shown in detail in FIGS. 1a and 2 can be fixed by means of bolts 23, as shown in FIG. four.

The support element 26 is adjacent to an inclined holder 18 having a U-shaped profile in cross section. The lower end of the jib 11 is fixed to the holder 18, fixed by a bolt 20. In the holder 18 and / or the jib 11, several adjacent holes can be made, providing different mounting positions of the locking bolt 20 and allowing the jaw 11. to be fixed in place. Another, that is, the upper end jaws 11 are inserted into an inclined holder 18.1 and fixed with a locking bolt 21. Both holders 18 and 18.1, forming angles of 45 ° with the vertical and horizontal, can be connected to the horizontal supporting element 17 and the vertical supporting element 26 with the possibility of changing the angle of inclination of 18.1 and holder 18 relative to the horizontal.

Two fasteners 9 and 12 are installed on both sides of the working platform 2, which in the example shown in Fig.1, 1b and 2, has a rectangular shape. In this example, there are two vertical posts 14 and 33 with an attached jib 11. The vertical posts 14 and 33 are located at some distance from each other, with the second vertical post 33 installed on the second side 6b on the base plate 15. Between the posts 14 and 33 are horizontal the transverse beam 16, which serves as a support for the base plate 15, and the crossbars 29, 30 and 31 or 34.2, 35 and 36, as shown in FIG. 2, as well as the transverse beam 34, which serves as the support for another base plate 39. According to FIG. 1a, the ends of the crossbars 30 and 31 are installed in single links 13.1 and 13.2. The connecting links 13.1 and 13.2, as shown in the example of the connecting link 13.3 in figure 4, are attached to various mounts 12 and 9 or, as shown in figure 2, directly to the vertical posts 14 and 33.

The connecting links together with the fastener 5 can also be mounted on the uprights 14 and 33. The connecting links 13.1 and 13.2, as mentioned above and shown in FIG. 1a, serve as supports for the horizontal bars 30 and 31. According to FIG. 2, the bar 34.2 is connected with the connecting link 13.4 mounted directly on the mount 5. The crossbars 29-31 and 34.2-36 together with the connecting links 13.1-13.4 and the transverse beams 16 and 34 can be fixed with bolts (not shown in the drawing), and the crossbar 36 can be made in kind of commission nya.

The crossbars 29-31 and 34.2-36, firstly, limit the working platforms 2 and 2 'from the sides and serve to ensure the safety of people on the platforms 2 and 2'. Secondly, the transverse beams 16 and 34 also serve as supports for the base plates 15, mounted depending on operating conditions at various heights. This is done so that as construction progresses, it is possible to move up and work at different levels when using one or more work sites 2 and 2 '.

The construction shown in FIG. 2 comprises an additional upright post 14.2 and a back post 37, the lower end of the upright post 14.2 being connected via a connecting device using a rigid or detachable connection to the transverse beam 34.
