A suspension support device that is used when a lower floor ceiling is suspended from the lower surface of an upper floor using a board, and is particularly designed to reduce noise such as vibration sounds and impact sounds generated on the support side. The present invention relates to a hanging support device that has improved soundproofing properties and sound insulation properties so as not to transmit the sound to the sides.

[Conventional technology]

For example, in steel frame and reinforced concrete building structures,
A concrete form board formed from a metal steel plate is used as at least a part of the concrete formwork for the upper floor, and this is left on the lower surface of the upper floor, and the concrete form board is On the other hand, conventionally, as a ceiling suspension support structure in which the lower floor side ceiling is suspended and supported,
The configurations shown in FIGS. 5 and 6 have been proposed.

FIG. 5 is a sectional view schematically showing the general structure of a ceiling suspension support structure according to a conventional example, and FIG.
Figures (a) and (b) are a perspective view and a cross-sectional view showing a concrete form board made of metal steel plate applied to the above suspension support structure.

In other words, in the conventional structure shown in FIGS. 5 and 6, the concrete form board (hereinafter also simply referred to as form board) (1), which also serves as a fabric board, is formed by forming a metal steel plate so that the longitudinal direction A plurality of reinforcing protrusions (2) are folded downward in a triangular cross-sectional shape in parallel to each other along the longitudinal direction, and engaging portions (
3), (4), and flat parts (5) at both ends.
, (5) respectively.

Therefore, when constructing a building, the steel frame section extends horizontally from the concrete main column section (6), which includes steel frames and reinforcing bars and is cast in the vertical direction.

In this case, the concrete form board made of the metal steel plate (
The hook locks each flat part (5), (5) at both ends of 1), and each engaging part (3), (4) on adjacent both sides.
) are attached to each other and laid, and this formwork board (1) is used as a part of the floor formwork as concrete formwork, and the upper part of the formwork board (1) is also fitted with reinforcing bars, etc. as appropriate. By arranging reinforcement and pouring concrete in this state, concrete body parts such as the wall part (8) and the floor part (9) are constructed respectively. For the frame board (1), connect it to the floor part (9
), and during the subsequent interior decoration process, attach multiple metal support bolts (t = y < 10) to the upper end of the remaining formwork board (1). The ceiling part (11) is directly supported by each of these support bolts (1(1)).

However, in the case of the suspension support structure for the ceiling part having the conventional configuration as described above, the concrete form board (1) made of metal steel plate is attached to the floor part (9) on the upper floor side that constitutes the concrete frame part. A plurality of supporting bolts (10
), the ceiling part (11) on the lower floor side is directly suspended and supported, and in this way, the floor part (9) on the upper floor side and the ceiling part (II) on the lower floor side Because they are connected by metal members that have relatively good transmission of sound and vibration, noise such as vibration noise and impact sound generated on the upper floor (9) is There is an undesirable problem in that the light is transmitted straight to the ceiling on the lower floor side.

In addition, these problems are not limited to the above-mentioned ceiling suspension support structure, but also apply to other suspension support structures, and are an issue in architectural structures. Immediate improvements are desired.

The object of the present invention is to provide a new suspension support device for this type of architectural structure.

(Means for Solving the Problems) In order to achieve the above object, a suspension support structure for a ceiling in a building according to the present invention includes an upper support member provided with an attachment section at the upper end, and an upper support member provided at the lower end. Attachment is such that the lower support member provided with the part is integrally connected in a separated state by a member having vibration absorbing properties.

That is, the first invention includes an upper support member having an attachment part at its upper end, and a lower support member having an attachment part at its lower end, and the lower end of the upper support member and the lower support member. In the enclosing part extending from either one of the upper ends of the member,
The flange extending from the other side is inserted, and a rubber material or a synthetic resin material having vibration absorbing properties is filled and solidified in the holding part, and the flange part is inserted through the solidified vibration absorbing member. This is a suspension support device for an architectural structure, characterized in that the suspension support device is configured such that the suspension support device is supported in an isolated state within a holding part.

Further, the second invention has an upper support member provided with an attachment part along almost the entire length, and a lower support member provided with an attachment part at its lower end, and is screwed to the lower end of the upper support member. A holding part is provided, a flange part extending from the other side is inserted into the holding part, and a rubber material or a synthetic resin material having vibration absorbing properties is filled and solidified in the holding part,
This suspension support device for an architectural structure is characterized in that the flange portion is supported in an isolated state within the enveloping portion via the solidified vibration absorbing member.

[For production]

That is, in the first invention, the flange portion extending from the other is fitted into the enclosing portion extending from either the lower end of the upper support member or the upper end of the lower support member. The two are integrally supported while being isolated through a vibration absorbing member, and a rubber material or synthetic resin material having vibration absorbing properties is filled and solidified in the enclosing part, and this solidified vibration absorbing material is used. Since the flange part is isolated and supported within the enclosing part through the member, vibrations such as vibration sounds and impact sounds generated on one side are absorbed by the intervening vibration absorbing member, and this vibration is transferred to the other side. In the second invention, in addition to the above-mentioned effect, the upper support member can be inserted and fixed from either above or below during operation. This increases the degree of freedom in directionality and improves workability in a narrow space, and since the holding part is threaded with the upper support member, it is possible to work in a narrow space with ease.

Further, since the holding part (34) is separate from the upper support member, workability in a narrow space is very good.

In addition, in the above embodiment, the case where this suspension support device is applied to a suspension structure of a lower floor ceiling from an upper floor floor is described, but it can also be applied to other similar suspension structures. Of course, similar actions and effects can be obtained with this S.

Further, in the embodiment, a case was described in which a concrete form board formed into a specific shape was used, but any form board that serves a similar purpose may be used.
