Abstract

PROBLEM TO BE SOLVED: To locate a downspout at any arbitrary position during work by giving freely slidable shape to an upper bend pipe connected to an upper downspout at the downstream side and also to an lower bend pipe to be connected to a lower downspout at upstream side and fitting them together. SOLUTION: An increased pipe diameter portion 11 is provided at the upstream side of an upper bend pipe 1, and an inner sliding pipe 12 is formed at the downstream side through an intermediate bend portion of about 45 deg.. The lower bend pipe 2 is provided with an outer slidable pipe 21 having a shape fitted to the outside of the inner slidable pipe 12 and a lower end portion 22 fitting and connectable to the increased pipe diameter portion of the downspout at downstream side. Material should be stainless steel plate. When working, the inner slidable pipe 12 and the outer slidable pipe 21 must be first slided and adjusted and located near a projected portion of a building, to which the pipe joint will be secured. Next, the downspout is connected to the increased pipe diameter portion 11 and the lower end portion 22 respectively and are fixed to wall surface with metal fittings. By doing this, the downspout can be built along the wall surface in alignment with the shape of the projected portion from the building. Thus, work can be performed very easily and good outer appearance of joints can be provided.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is formed by bending a metal plate such as a stainless steel plate into a bent tubular shape and slidably combining them.
The present invention relates to an adjusting joint used when connecting and constructing by shifting the axial position of a vertical rail.

[0002]

2. Description of the Related Art A metal ledge for construction along a wall surface of a building such as a building is, for example, stainless steel.
A pipe formed by forming a plate having a thickness of about 6 mm to 1.0 mm into a tubular shape is used. The upper part of this vertical tower is connected to the drain on the rooftop and fixed on the wall of the building with metal fittings.

However, the place where the wall surface of the building is constructed is not always flat, and there are various protruding structures such as windows, bodies and pipes. For example, it is not possible to drop a straight line from the upper part to the ground straight in such a place, so it is common to call it in the middle in various directions, and then drain it to a buried pipe on the ground. there were.

[0006] This routing requires adjustment not only in the plane direction along the wall surface but also in the vertical direction protruding from the wall surface depending on the shape of the building. That is, in many cases, a projecting portion of several cm to several tens of cm is generated from the wall surface in relation to the external structure of the building. In the case of hanging a vertical tower on the wall surface of such a building, it was necessary to draw around the vertical tower so as to avoid the protruding portion.

[0005]

The routing work for avoiding the projecting portion of the building requires a lot of connecting parts, which is troublesome. In other words, since the connecting parts are manufactured and adjusted by measuring the dimensional length of the construction site one by one, the cost is high. Further, in the case of stainless steel plate, etc., it is difficult to process, so the precision of the parts is likely to be insufficient, and there is a functional concern such as rain leakage, and the appearance after construction cannot be said to be sufficient.

[0006] Further, if the position of the buried pipe deviates from the position on the ground, the connection itself may occur.

[0007]

In order to solve the above-mentioned problems, the adjusting joint according to the present invention has a
It can be slidably adjusted when it is drawn around the projecting part of the building, and its adjustment width can be set arbitrarily. That is, a combination of an upper bending pipe that expands the water side for vertical fitting to the outside and a water bending side that is a thin tube to the thickness of the material and a lower bending tube that can be slidably fitted on the thin tube and adjusted The construction can be done by adjusting the distance from the wall of the vertical tower.

Alternatively, when adjusting the deviation from the buried pipe, the adjustment can be performed in the direction parallel to the wall surface by changing the direction of the adjusting joint.

[0009]

[Operation] As the vertical construction has been performed from above along the wall surface of the building, connect the water side of the upper bending pipe at the projecting portion of the building, and then fit the lower bending pipe below it. , Adjust the projecting position while sliding it. If you connect the lower vertical to the water side of the lower bent pipe, you can install it in a position where the vertical is staggered, and if it is more complicated, you can easily carry out the work of routing the vertical by repeating such work. Can be done. (FIG. 4)

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to an embodiment shown in the accompanying drawings. FIG. 1 is an exploded perspective view of an adjusting joint A which is an embodiment according to the present invention, and FIGS. 2 and 3 are side views when they are connected. The table B adjacent to the upper part has a cylindrical shape made of a stainless steel plate having a thickness of about 0.6 mm to 1.0 mm, and the adjusting joint A connected to the lower part thereof is made of the same stainless steel plate.

The adjusting joint A is constructed when the center axes of the vertical rails are displaced and connected, and is composed of an upper bending pipe 1 and a lower bending pipe 2. The upper bent portion of the upper bent pipe 1 on the water side is provided with an expanded pipe portion 11 for external fitting on a vertical end, and an inner slide which is a thin pipe having a material thickness on the water side through a bent portion in the middle. A moving tube 12 is formed. In the present embodiment, the angle of this bent portion is bent at about 45 degrees, but as will be described later, it is naturally possible to use other angles.

Further, a lower bent tube 2 connected to the upper bent tube 1
Has a shape that can be slidably fitted on the underwater side of the upper bent pipe 1, and is fitted and connected to the expanded portion 3 of the tee B and the like connected to the lower side on the underwater side. . That is, the sliding fitting depth of the upper bending tube 1 and the lower bending tube 2 is used to adjust the deviation of the vertical joints to be connected. If the amount of deviation is as large as W2, the fitting may be shallow (Fig. 3).

That is, at the time of construction, the adjusting joint is slid according to the projecting portion of the building to be constructed, and the fitting depth is adjusted to an appropriate fitting depth to match the amount of shift. After that, if the vertical blades are connected to each other and the metal fittings C are used for the construction, the construction can be carried out according to the change of the wall surface D (FIG. 4).

Further, in FIG. 5, when the angle of the bent portion is changed to increase the angle to X which is about 60 degrees, the adjustment range W described above can be widened, and the angle can be decreased as shown in FIG. When Y is set to about 30 degrees, the adjustment range is narrow, but on the other hand, fine adjustment is possible.

In this embodiment, the adjustment of the displacement with respect to the wall surface has been described, but it is possible to sufficiently cope with the displacement between the vertical shaft B and the buried pipe, and the length of the sliding portion is increased. If so, the adjustment range is widened, and the application range within the scope of the present invention is wide.

[0016]

As described above, in the vertical joint adjusting joint according to the present invention, when the vertical rail to be constructed along the wall surface is constructed so as to avoid the projecting portion of the building, the sliding portion is moved and displaced. By adjusting the width, the work can be performed very easily.

Further, by using a bending tube having different angles of inclination above and below the inclination, the adjustment range can be widened or the adjustment range can be narrowed to enable fine adjustment.

[0018] Therefore, the appearance after construction will be good without forcibly deforming the vertical head.
Since the material of the present invention is not particularly limited, the present invention can be carried out using other metal plates or synthetic resins in addition to the stainless steel plate of this embodiment.
