[0003]

[Problems to be solved by the device]

 In the frame scaffolding as shown in FIG. 9, in case of rain, the worker on the uppermost tread 6 is exposed to the rain and the work efficiency is reduced. For the workers on the treads 6 below, the treads 6 above them will serve as a rain shield, but there is usually a gap between the treads 6 and the above-mentioned uppermost treads. From then on, it rains and drops on the workers through the gaps, and it does not play the role of avoiding much rain. Moreover, since the space between the frame scaffold and the outer wall of the building T has an open ceiling, rain will fall directly into the above space, not only the workers but also the building under construction. The outer wall is also directly exposed to rain, which leads to deterioration of the quality of the outer wall during work such as painting.

【Example】

 FIG. 1 is an overall perspective view showing an example of a framed scaffolding with a roof to which the present invention is applied. First, the overall outline will be described by using a large number of building frames 1 and cross bracing members 3 for each stage. A building frame assembly is constructed, and they are stacked in four stages, for example. The treads 6 are laid over the building frames from the bottom to the third, and the roof M, which is the main part of the present invention, is mounted on the building frames at the top. ing. The roof M is arranged at a position higher than the height of the building. Framework A space of about 30 cm to 50 cm is secured between the scaffold and the building T.

The single member of each building frame 1 is formed by using a round pipe as a raw material, and the shape thereof is a flat gate-shaped or torii type. The building frames 1 are arranged with an interval of 900 mm to 1800 mm between adjacent building frames 1 and are connected in parallel to each other by the X-shaped cross bracing members 3 on the building side and the road side. , Thereby constructing a three-dimensional building frame assembly at each stage. Although not shown, the tread 6 has a pair of left and right hooks integrally at both ends in the lengthwise direction. By hooking these hooks on the upper end horizontal pipes 1b of the adjacent building frames 1, , It is fixed at the upper end of the adjacent building frames 1.

In FIG. 2 showing a side view, the lower end of the first-stage building frame 1 is installed on the ground through a jack base 2 or on a foundation surface such as a floor plate, and the second-stage building frame 1 The lower end of is connected to the upper end of the first-stage building frame 1 via a joint member (connecting pin) 8. The lower ends of the third- and fourth-stage building frames 1 are connected to the upper ends of the second- and third-stage building frames 1 via joint members (connection pins) 8 similar to the above. .

The roof M is composed of a plurality of pipe legs 11, 11 a and 12, a seat mount 15, a roof seat 16 and the like. A short leg 11 is provided at a position corresponding to the vertical pipe 1a on the building side of the building frame 1, and a long leg 12 is provided at a position corresponding to the vertical pipe 1a on the road side. The lower ends of the legs 11 and 12 are The uppermost stage, that is, the upper end of each vertical pipe 1a of the fourth-stage building frame 1 is connected via the joint member (connecting pin) 8 for the building frame joint. The seat mounting base 15 is fixed to the upper ends of the legs 11 and 12 so as to integrally connect them, and the roof seat 16 is fixed to the seat mounting base 15. The roof sheet 16 covers the entire upper part of the frame scaffold, and extends to a position above the building through the space between the building T and the scaffold. That is, it covers the upper part of the scaffold, the upper part of the clearance space, and the upper part of the building. As described above, since the leg 12 on the road side is made long and the leg 11 on the building side is made short, the seat mounting base 15 is inclined so that the building side becomes low. The roof sheet 16 is also inclined so that the building side becomes lower, so that the rain falling on the roof M is guided to the upper surface of the building T without falling to the road side. The intermediate leg 11a is an optional member used in place of the short leg 11 when the roof M is mounted on a building frame whose building frame size is narrower than that shown in the drawing. It is set to match the width of a narrow building frame (for example, 900 mm width).

With reference to FIG. 6, a joint mechanism for connecting the building frame 1 and the building frame 1 thereabove through a joint member 8 will be described. The joint member 8 is formed in a pin shape having a diameter that can be fitted to the inner peripheral surface of the vertical pipe of the building frame 1, and has a flange 20 having a diameter larger than the inner diameter of the vertical pipe of the building frame 1 in the central portion in the vertical direction. Thus, the pin portion is divided into upper and lower pin portions 20a 1 and 20b 2. Circumferentially extending long grooves 22 and 23 are formed in the upper and lower pin portions 20a and 20b, respectively, and the upper long groove 22 is provided with a guide groove 22a extending upward from the end of the long groove 22 to the upper end edge. Has been formed. A handle 21 for rotating the flange 20 is formed on the flange 20. On the other hand, in the upper end portion of the vertical pipe 1a of the building frame 1, as shown in the lower half portion of FIG. 6, an inward projection 24 that can be engaged with the lower long groove 23 is formed, and the lower end of the vertical pipe 1a is formed. As shown in the upper half of FIG. 6, inward projections 25 that can engage with the upper long grooves 22 are formed in the respective portions. The lower pin portion 20b of the joint member 8 is fitted to the inner peripheral surface of the upper end portion of the vertical pipe 1a of the lower building frame 1, and the projection 24 is engaged with the lower long groove 23. It is locked so as not to come out upward, and is rotatable within the range of the length of the long groove 23. With respect to the joint member 8 attached to the upper end of the lower building frame 1 as described above, the upper building frame 1 is attached to the lower end of the vertical pipe 1a with the position of the protrusion 25 aligned with the position of the guide groove 22a. Part is fitted to the upper pin part 20a, and then the joint member 8 is rotated in the direction of the arrow with the handle 21 to shift the projection 25 in the long groove 22 to the side opposite to the proposed groove 22a. Thereby, the upper building frame 1 is locked so as not to come out upward.

In contrast to such a joint mechanism, the lower ends of the roof legs 11 and 12 made of pipes have the same inner diameter as the inner diameter of the vertical pipe 1a of the building frame 1, and An inward projection 28 similar to the inward projection 25 at the lower end of the vertical pipe 1a is formed. Therefore, the roof legs 11 and 12 are fixed to the upper end of the building frame 1 by fitting into the upper pin portion 20a of the joint member 8 and engaging with the long groove 22 as in the case of connecting the building frames. be able to.

FIG. 3 shows an exploded perspective view of the roof M. The roof sheet 16 is stretched over a rectangular pipe frame body 17, and the outer peripheral edge of the roof sheet 16 is, for example, , Is fixed to the frame body 17 by a connecting cord. The width D of the roof sheet 16 is substantially equal to the center distance D1 between the adjacent building frames 1. The cross section of each seat mounting base 15 is formed in a gutter shape with a U-shape open upward, and at least the building side is open. Seat mounting brackets 30 are welded on both sides of each seat mounting base 15 at equal intervals in the mounting base length direction. Each of the brackets 30 is long in the mounting base length direction and is on the front side (road side). The long holes 31 for bolt insertion, each of which has an open end, are formed. On the other hand, a mounting piece 32 corresponding to the bracket 30 is welded to the frame body 17 of the roof sheet 16.

FIG. 4 is an enlarged cross-sectional view of the seat mounting base 15 (IV-IV cross-sectional enlarged view of FIG. 2). A bolt 35 is welded to the mounting piece 32 of the frame body 17 so as to project downward. ing. The frame bodies 17 of the adjacent seats 16 are fitted in the seat mount 15, and the mounting pieces 32 of the frame body 17 are mounted on the bracket 30. The frame body 17 of the seat 16 is fixed to the seat mount 15 by being inserted into the hole 31 and tightened with the nut 37 via the L-shaped washer 36. As shown in FIG. 5, the L-shaped washer 36 bends upward on the building side (lower side), that is, on the side opposite to the open end of the long hole 31, and engages with the edge of the bracket 30. The frame body 17 is prevented from shifting to the road side.

7 and 8 show a joint portion between the roof leg 11 and the building frame 1, and in addition to the structure in which the joint member 8 is connected as described above, an L-shaped clamp member 40 is used to The connection between 11 and the building frame 1 is reinforced. That is, openable and closable clamps 44 are provided on both sides of the L-shaped plate 41, and the clamps 44 are held by the legs 11 and the upper lateral pipe 1b of the building frame 1.

At the time of assembling the scaffold, in FIG. 2, the building frame 1 is assembled from the lower tier, and the upper tier is successively added by the joint member 8. Then, at the time of assembling the uppermost stage, legs 11 and 12 are added to the upper side of the same through the joint member 8 similar to the above, and the roof sheet 16 is fixed thereon. As a result, a scaffold with a roof as shown in Fig. 1 is completed. Since the roof M covers the space above the scaffold and the space between the scaffold and the building, rain is prevented from directly pouring on the worker on the tread 6 even in rainy weather. The rain that falls on the roof M does not fall on the road side because it rains on the upper side of the building T due to the inclination of the roof sheet 16. Also, it is possible to prevent rain from being transferred into the space between the frame scaffold and the outer peripheral surface of the building T, and protect the outer peripheral surface of the building during construction. In addition, rainwater flowing between the roof sheets flows into the gutter-shaped seat mounting base 15 and is guided to the upper side of the building due to its inclination. When installing a roof on a scaffold that uses a 900 mm wide frame as the building frame 1, the long leg 12 and the intermediate short leg 11a of Fig. 2 are respectively connected to the pipe of the 900 mm building frame through joint members. Connecting.
