In order to solve the above problems, the invention of claim 1 uses a linear chute in which the upper surface of one end and the other end are open, and is temporarily installed outside the building. On the scaffolding, a structure is adopted in which the chutes are arranged in a tilted state so that the ends of the upper and lower chutes are positioned vertically so as to form a slope.

Here, the chutes are formed in an upward U-shaped section, a rectangular tubular shape, or a circular pipe, and the chutes are sequentially arranged so as to form a fold-back slope at an inclination angle at which construction waste slides. It

According to a second aspect of the present invention, a chute formed so as to have an arcuate planar shape is used, and the upper and lower chutes are spirally connected to a scaffold temporarily installed outside the building with the chute inclined. It adopts a configuration in which the slopes are formed by arranging at.

Here, the chute is formed into a U-shaped or rectangular tube-shaped or circular pipe having an upward cross section, and the chute is sequentially connected vertically at an inclination angle at which construction waste slides to form a spiral slope. There is.

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 to 5 show a first example of a unloading device which uses a straight chute and has a fold-back type slope. The chute 1 is straight and has an upward U-shaped or square-cylindrical cross section. When the length direction is tilted by a predetermined angle, both ends are vertical short-angled cylinders, and the upper surface of one end, which is the upper side, and the lower surface of the other end are both horizontal and have the same opening diameter. It is a few.

The scaffold B temporarily installed on the outside of the building A connects the building frames B ₁ standing upright at regular intervals to each other with braces B ₂ and scaffolding plates, and moves the building frame B ₁ upward and upward. The chute 1 is constructed by connecting, and the chute 1 is, for example, in a slanted state between a width that fits inside the building frame B _{1 as} shown in FIG. 2 and two spans of the facing interval of the building frame B ₁ as shown in FIG. It is formed to a length that can be accommodated, and the building frame B ₁ is attached to both ends of the chute _1.
The hooks 4 and 4 which are locked to the horizontal rail B ₃ are fixed.

Therefore, the chute 1 is necessary for sliding the building waste in a bag when the hooks 4 and 4 at both ends are locked to the horizontal rail B ₃ of the building frame B ₁ at different heights as shown in FIG. while being extended between Do inclination angle rungs B _3, the upper and lower chute 1 when folded arranged vertically so that the inclination directions are reverse arrangement, the upper end of the lower connecting port 3 and the lower chute 1 of the upper chute 1 A slide-type unloading device that communicates with the connection port 2 and continues vertically in a zigzag state is configured.

The material forming the chute 1 is a steel plate,
When stainless steel, synthetic resin, or the like is used and flanges are provided on the outer peripheries of the upper and lower connecting ports 2 and 3 or a rectangular tube or circular pipe has a cross-sectional structure, as shown in FIG. May be provided, and the input port 5 can be opened and closed by a lid.

The lowermost part of the unloading device is shown in FIGS.
As shown in FIG. 3, the lowermost chute 1a is arranged so as to project toward the outside of the scaffold B by a wire 6 or the like with respect to the scaffold B, and the construction waste has fallen to the ground directly below. A container 7 or a stage for accommodating the is provided, and in the case of the stage, it may be put into the container after sorting.

Further, the chute 1 is desired to be lightweight because it can be lifted to a high place, and not only the material is selected, but also the chute 1 is divided into two parts at the central portion in the longitudinal direction and is connected to the flange joint by bolts. Good.

The first example of the present invention has the above-mentioned structure, and when the building A is constructed, the scaffold B is installed on the outside thereof,
Build upwards as construction progresses.

With respect to the scaffold B, the chute 1 is installed between the cross rails B ₃ and B ₃ so as to be inclined, and the upper and lower chutes 1 are arranged so as to be reversely inclined, as shown in FIG. , Forming a straight-backed slope.

The construction waste generated in the building A can be put into the chute 1 through the upper end connection port 2 of the chute 1 located at the uppermost part in the state of being packed in a bag, and the construction waste can be stored in the chute 1. And slide back to move from the upper shoot to the lower shoot in a loopback manner
It is dropped and stored in the container 7 immediately below from the lower end connection port 3 of a.

In this way, the construction waste will slide down just by throwing it into the chute 1, and the construction waste can be easily unloaded on the ground, and the floor height of the building A will rise and the scaffold B will increase. Since it is also added upward, the chute 1 may be installed at the upper position each time, and the slope may be sequentially extended upward in a folded shape.

If each of the chutes 1 is provided with the charging port 5 on the upper surface on the lower end side, the construction waste can be charged even in the middle of the continuous slope, and the construction waste from any floor of the building A. It is possible to put in things.

Next, a second example shown in FIGS. 6 and 7 shows another example of a folded-back slope using a straight chute, and the chute 1a has a straight trough shape with an upward U-shaped cross section. The one end that is on the upper side when tilted is closed by the end wall 8, and the upper surface and the other end are open.

In the chute 1a, the side walls 9 on both sides are sloped so as to open upward so that the chute 1a can be sequentially fitted at the time of stacking to achieve a low bulk stacking.

In order to attach the chute 1a to the scaffold B to form a slope, as shown in FIG. 6, a pipe B ₄ is erected on the upper part between the vertical columns on both sides of the building frame B ₁ using a single pipe clamp.
The chute 1a is attached by fixing one end of the chute 1a on the pipe B ₄ with a single pipe clamp 10 attached to the lower surface thereof, and the lower surface of the middle part of the chute 1a is adjacent to the building frame B ₁
If placed on the rungs B _3, the chute 1a is mounted in an inclined state to the scaffold B.

In this way, if the chutes 1a are attached to the upper and lower sides of the scaffold B so as to be inclined in the opposite directions,
The open lower end of the upper chute faces directly above the upper end of the lower chute, forming a fold-back slope in a state where the upper and lower chutes 1a are not directly connected, and unloading construction waste as in the first example. You can do it.

Next, a third example shown in FIGS. 8 to 12 is
It is a case where a spiral slope is formed, and the chute 11
Is a semi-circular plane with a circular pipe having an upward U-shaped cross section, a rectangular tubular shape, both ends open, and both edges are vertical with a predetermined inclination angle. In the case of a U-shaped cross section, it is preferable that both side walls are outwardly opened upward.

Hooks 1 are provided on the lower surfaces of both ends of the chute 11.
2 is provided, and as shown in FIGS. 8 and 9, the hook 12 is attached to the crosspiece B ₃ of the building frame B ₁ so that the hook 12 is attached to the scaffold B so as to be in a predetermined inclined state, and the upper and lower chutes are attached. If 11 is attached so as to be continuous, a spiral slope will be formed.

The lowermost chute 11a is linear and is installed so as to project to the outside of the scaffold B.

The chute 11 is made of steel plate, stainless steel,
Although it is made of synthetic resin, the bottom surface of the chute 1 is made smooth so that the bag-like construction waste can slip off smoothly.
The bottom surface of 1 may be formed by arranging round shafts 13 along the length direction in parallel in the width direction.

The third example of the present invention has the above-mentioned structure. If the chute 11 having a plane semicircular shape is attached to the scaffold B so as to be successively inclined from the lower part to the upper part, the vertical direction of the building frame B ₁ can be increased. A spiral slope can be formed by winding a pillar, and the construction waste generated in each floor of the building A is put in a bag and put into the chute 11, which slides along the chute 11 to the ground. You can take it down.
