Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a building frame forming a framed scaffold, and more particularly, to a retractable building frame whose height can be adjusted so that the scaffolding can be assembled at a desired height.

[0002]

[Prior Art]

 Conventionally, work such as repair and painting of buildings has been carried out using frame scaffolds provided on the outer periphery of the building or inside the building.

As for the frame scaffolding, as shown in FIG. 4, a large number of building frames 1 in which steel pipes for scaffolding are processed in advance in a factory into fixed frame units are arranged at predetermined intervals in the lateral direction as shown in FIG. However, a scaffolding plate 3 for workers to work on is substantially horizontally bridged between the building frames 1 arranged opposite to each other and between the building frames 1. Then, the braces 5 having a rigid structure for the scaffold are connected in an X-shape to the side portions of the building frames 1 arranged so as to face each other.

Further, although not shown, in the case of performing work in a high place of a building, a building frame is further added to the upper part of the building frame to extend the frame scaffolding upward. Thus, in the frame scaffolding 7 configured as described above, various works can be easily performed by using the scaffolding plate 3.

[0005]

[Problems to be solved by the device]

 However, since the height of the conventional building frame 1 as shown in FIG. 4 cannot be adjusted, it has been pointed out that the frame scaffolding cannot be assembled at a height according to the situation of the site.

Further, conventionally, several types of building frames having different heights are manufactured, but in order to bring these several types of building frames to the site in advance, it is necessary to secure a storage place for them. However, there was a drawback that these building frames sometimes hinder the work.

[0007] The work of appropriately selecting these building frames according to the situation and moving the building frames from their storage location to the installation location of the framework scaffolding is also very troublesome. The present invention has been devised in view of such circumstances, and provides a construction frame of a frame scaffold capable of adjusting the height so that the frame scaffold can be assembled at a desired height according to the situation of the site. With the goal.

[0008]

[Means for Solving the Problems]

 In order to achieve such an object, the present invention provides a large number of laterally spaced scaffolds, bridges scaffolding boards on or between them, and connects braces between each side pillar. In a building frame that forms a frame scaffold, the pillar is composed of an outer pipe and an inner pipe that has a diameter smaller than the inner diameter of the outer pipe and is expandable and contractable from inside the outer pipe, and the inner pipe is fixed to the outer pipe. It is equipped with a fixing means.

[0009]

[Action]

 According to the present invention, the height of the building frame can be adjusted according to the situation of the site by expanding and contracting the inner pipe of each strut from the respective outer pipe and fixing it to each outer pipe.

[0010]

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In FIG. 1, reference numeral 9 denotes a building frame according to an embodiment of the present invention, which is manufactured from a steel pipe for scaffolding. Two columns 11 of the building frame 9 include an outer pipe 13 and an outer pipe 13, respectively. The inner tube 15 has a diameter smaller than the inner diameter of the inner tube 15, and the lower end of the inner tube 15 is inserted into the outer tube 13.

Further, a scaffolding plate mounting pipe 17 is laid over the upper ends of the inner pipes 15 of both columns 11, and each inner pipe 15 is expanded and contracted in the vertical direction from the inside of the outer pipe 13 as shown in FIG. As a result, the height of the scaffolding plate mounting tube 17 can be changed.

A substantially L-shaped reinforcing frame 19 that reinforces the scaffolding plate mounting pipe 17 is attached between both inner pipes 15 and the scaffolding plate mounting pipe 17, and each outer pipe 11 has A substantially L-shaped reinforcing frame 21 is also attached to the inside.

Further, as shown in FIG. 3, a pair of pin insertion holes 23 are provided in the upper peripheral wall of the outer tube 13 so as to face each other, and the fixed support pins 25 are inserted into the pin insertion holes 23. It has become so. Further, the shaft portion 25a of the fixed support pin 25 is provided with a split pin insertion hole 29 into which the split pin 27 is inserted, and by inserting the split pin 27 into the split pin insertion hole 29, the pin insertion hole is formed. The fixed support pin 25 inserted in the 23 is prevented from falling off.

On the other hand, a plurality of pairs of pin insertion holes 31 into which the fixed support pins 25 can be inserted are also provided in the peripheral wall of the inner tube 15 so as to face each other at a predetermined interval in the vertical direction, as shown in FIG. As described above, the inner pipe 15 is fixed to the outer pipe 13 by inserting the fixed support pin 25 into the pin insertion holes 23 and 31.

Since the building frame 9 according to the present embodiment is configured in this way, when performing work on site, the inner pipes 15 of the columns 11 of each building frame 9 are expanded and contracted from the respective outer pipes 13. After that, the predetermined pin insertion hole 31 of the inner pipe 15 and the pin insertion hole 23 of the outer pipe 13 are aligned with each other, and the inner and outer pipes 13 and 15 are fixed by the fixed support pins 25 to keep the building frame 9 at a constant height. Just set it.

As in the conventional case, a large number of such building frames 9 are laterally arranged at a predetermined interval, and scaffolding boards for workers to work are provided on or between the facing building frames 9. If the braces are connected in an X-shape between the columns 11 of each building frame 9, the frame scaffolds of a certain height will be formed.

In addition, depending on the situation of the site, when a frame scaffolding higher than the above frame scaffolding is required, for example, when forming the frame scaffolding, each of the columns 11 of the building frame 9 as shown in FIG. The pipes 15 are extended from the respective outer pipes 13, and as shown in FIG. 3, the pin insertion holes 31 of the selected inner pipes 15 and the pin insertion holes 23 of the outer pipe 13 are aligned and fixedly supported. After inserting the pin 25, the split pin 27 is inserted into the split pin insertion hole 29 to fix the inner pipe 15 to the outer pipe 13, whereby the height adjustment of the building frame 9 is completed.

If a frame scaffold is made using the building frame 9 whose height is adjusted in this way, a higher frame scaffold will be formed. As described above, in this embodiment, both columns 11 of the building frame 9 are configured by the outer pipe 13 and the inner pipe 15 that is expandable and contractable from within the outer pipe 13, and the outer pipe 13 and the inner pipe 15 are connected to each other. Since it is fixed by the fixed support pin 25, the height of the building frame 9 can be adjusted according to the situation at the site.

Therefore, according to this embodiment, the frame scaffolding can be assembled at a desired height without using a plurality of types of building frames, and several types of building frames having different heights can be prepared on the site as in the past. There is no need to keep it in place, and there is no need to move the building frames of other heights from their storage location to the installation location of the frame scaffolding depending on the situation, improving workability on site. It has the advantage that it can.

In the above embodiment, the outer pipe 13 and the inner pipe 15 are fixed by using the fixed support pins 25, but the fixing means is not limited to the above embodiment, and other means may be used. Of course, it is also good.

[0021]

[Effect of the device]

 As described above, according to the construction frame of the present invention, the height can be adjusted according to the situation of the site, so that the frame scaffold can be assembled at a desired height without using a plurality of types of construction frames. In addition to being able to stand, it is no longer necessary to prepare several types of building frames with different heights at the site as before, and depending on the situation, building frames of other heights can be installed from the storage location to the frame scaffolding. It also has the advantage of improving workability on site, such as eliminating the need for work to move to a location.
