Description

Description: TECHNICAL FIELD The present invention relates to a suspension support device or a suspension support structure in a building, and more specifically, in a steel frame or reinforced concrete building structure, for example, a metal steel plate is formed. It is applied when lower floor ceiling is hung on the lower surface of the upper floor using the concrete formwork plate, and especially noise such as vibration noise and impact noise generated on the support side is supported. The present invention relates to a suspension support device or a suspension support structure having improved soundproofing and sound insulation so as not to be transmitted to the side.

[Conventional technology]

For example, in a steel frame or reinforced concrete building structure, a concrete form board formed by molding a metal steel plate is used as at least a part of the concrete formwork of the upper floor, and this is left on the lower surface of the upper floor. The structure shown in FIGS. 5 and 6 has been conventionally proposed as a suspension support structure for the ceiling part of the concrete form board so that the ceiling part of the lower floor is suspended and supported. ing.

Here, FIG. 5 is a cross-sectional view schematically showing a schematic configuration of a suspension supporting structure for a ceiling portion according to a conventional example, and FIGS. 6 (a) and 6 (b) are the same as above. FIG. 3 is a perspective view and a cross-sectional view showing a concrete form plate made of a metal steel plate applied to the above.

That is, in these conventional structures shown in FIGS. 5 and 6, a concrete form plate (also simply referred to as a form plate hereinafter) (1) which also serves as a cloth plate is formed by forming a metal steel plate in the longitudinal direction. A plurality of reinforcing ridges (2) are fold-folded downward in a cross-sectional triangular shape in parallel with each other along the ridge, and engaging portions (3) which can be attached to both sides in the longitudinal direction between adjacent ridges. ), (4), and flat parts (5),
(5) is provided for each of them.

When constructing a building, the main pillars (6) of the concrete are constructed by placing them vertically including steel bars and steel frames.
From this, in the horizontally extending steel frame part, here, between the beam members (7), (7) such as I-shaped steel, the ends of the concrete form plate (1) made of the metal steel plate are The flat parts (5) and (5) are hooked and locked, and the engaging parts (3) and (4) on both sides adjacent to each other are engaged with each other and laid,
This form board (1) is used as a part of the floor part formwork as a concrete formwork, and the reinforcing bars and the like are appropriately arranged on the upper part of the formwork board (1), and concrete is placed in this state. By arranging the concrete form parts such as the wall part (8) and the floor part (9), the concrete form board (1) is constructed in this case.
For this, leave it on the bottom surface of the floor (9), and at the time of interior decoration thereafter, attach a plurality of metal support bolts () to the remaining form plate (1). 1
0) is fixed by welding at the upper end and is hung, and the ceiling part (11) is directly supported by each of these support bolts (10).

[Problems to be Solved by the Invention] However, in the case of the suspension supporting structure for the ceiling portion according to the conventional example configuration as described above, regarding the concrete formwork plate (1) made of a metal steel plate, this constitutes the concrete skeleton portion. A plurality of supporting bolts (10) made of metal that are left in direct contact with the lower surface of the floor (9) on the upper floor side and are also directly welded to the concrete form plate (1).
The ceiling part (11) on the lower floor side is directly hung and supported by using, and thus, the floor part (9) on the upper floor side and the ceiling part (11) on the lower floor side are thus combined. Since the both are connected by each metal member having relatively good transmission of vibration such as sound, noise such as vibration sound and impact sound generated on the floor (9) on the upper floor side is generated. However, there is an unfavorable problem that it is transmitted straight to the ceiling portion on the lower floor side.

Further, such a problem is not limited to the above-mentioned suspension support structure of the ceiling portion, and is also similar in the case of other suspension support structures. Immediate improvement is desired.

The present invention is to improve the conventional problems as described above, and to meet the intended request, the purpose is to support the side of the body structure and the like in the building structure,
In the case of supporting the supported side such as the ceiling part, it is possible to suspend and transmit the vibrations such as acoustic waves between them so that they can be cooperatively and effectively suspended and coupled. It is an object of the invention to newly provide a lower support device or a suspension support structure.

A lower support member having a mounting portion is provided on the upper portion, and a flange portion extending from the other end is provided in the holding portion extending from one of the lower end portion of the upper support member and the upper end portion of the lower support member. A vibration absorbing member made of a rubber material or a synthetic resin material having a vibration absorbing property is inserted into the holding portion, and the flange portion is isolated from the inside of the holding portion via the vibration absorbing member. Since they are supported and integrated, vibration such as vibration noise and impact noise generated on one side of the upper support member and the lower support member, for example, the floor of the upper floor, is interposed between them. Can be effectively absorbed by the vibration absorbing member What is directly the vibration in the ceiling portion or the like other side of the lower floor side, without a fear that is transmitted,
Very good soundproofing properties can be obtained.

Further, as the structure of the suspension supporting device, since one flange portion is connected with the vibration absorbing member intervening so as to be surrounded from the periphery by the other holding portion,
Since the entire device is integrated as much as possible, it is easy to handle and the workability at the time of mounting and supporting can be improved. Therefore, the workability at the time of constructing a suspended support structure such as a ceiling is good.

According to the second aspect of the invention, in addition to the effects described above, the upper support member can be arbitrarily selected from above or below to be inserted and fixed at the time of work, and the degree of freedom in directionality is widened, so that the upper support member can be installed in a narrow space. Workability can be further improved, and
Since the holding portion is screwed with the upper support member, it is possible to easily perform work in a narrow space.
