DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a space filled with a long body (for example, a pipe or a cable) inserted into a through hole provided in a structure (for example, a floor, a ceiling or a wall). The present invention relates to a filler support for a through-hole capable of supporting a material.

[0002]

2. Description of the Related Art Conventionally, as a filler support for a through hole of this kind, as shown in FIG. 5, the through hole 2 is filled in the through hole 2 at the front side in the filling direction of the filler J. An annular support portion 20 having an integral structure capable of receiving the filler J,
A plurality of locking pieces 21 that can be locked separately are provided around the opening of the through hole 2, and a plurality of connecting sections 22 that respectively connect the locking pieces 21 to the support 20 are provided. The filler supporter is locked to the structure 1 by the locking piece 21, and the elongated body P is inserted into an insertion hole formed in the center portion of the support 20. A filler J was packed between the elongated body P and the through-hole wall 2a and supported by the support portion 20.

[0003]

According to the above-described conventional filler support for a through hole, since the support portion is integrally formed in a ring shape, the elongated body is already inserted and arranged in the through hole. When installing the filler support in the through hole in the state,
It is necessary to insert the end of the elongated body into the insertion hole of the support portion of the filler supporter, and to shift the filler supporter to the installation location along the longitudinal direction of the elongated body, which requires less installation time. There is such a problem.

[0004] In order to solve this problem, it has been proposed that the annular support portion is simply divided in the radial direction. However, when the support portion is divided, the number of parts increases, and there is a risk that a new problem that storage and handling properties are reduced may occur.

Furthermore, both the conventional filler support of the through hole and the one proposed by the above-mentioned improvement proposal lock a plurality of locking pieces around the opening of the through hole in a single state. Therefore, in the state where the locking pieces are locked in the through holes, the locking pieces individually bear the locking force, and the locking pieces are individually deformed. Will be. Therefore, for example, in a state where the filler support is installed in the through hole and the filler is filled and the elongated body is fixed, when an external force in the pushing direction acts on the elongated body, the external force is the plurality of the plurality of elongated bodies. There is a problem in that it acts directly on the locking pieces, easily deforms each locking piece, and makes it difficult to hold the elongated body stably.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the above-mentioned problems, to easily install a long body after installing a long body in a through hole, and to reduce the length with a small number of parts. An object of the present invention is to provide a filler support for a through-hole capable of stably holding a scale.

[0007]

In order to achieve this object, a feature of the "filler support for through-hole" according to the present invention is that the filler is filled in the through-hole provided in the structure in the front side in the filling direction. An annular supporting portion capable of receiving the filler filled in the through-hole and an annular locking portion capable of being locked around an opening of the through-hole are separately formed in a radial direction. Divided and formed, and provided a connecting portion for separately connecting the divided support portion and the divided locking portion corresponding to the depth direction of the through hole,

[0015] Further, it is possible to freely lock on the locked portion, and
If an annular lid member is provided to cover the surrounding space while being locked to the locked portion, it is possible to prevent the filler filled in the surrounding space from being exposed, and the filler is It is possible to prevent deterioration due to direct influence of light or heat. And, for example, even when filled with a heat-expandable filler such as used for fire-resistant penetrations,
Good sealing performance of the filling space is ensured, the thermal expansion force of the filling material is effectively applied, and the effect of closing the through hole can be maintained (corresponding to claim 5).

If the lid member is formed by being divided in the radial direction and a lid connecting portion is provided which can be connected and fixed in a state where the divided lid members are combined with each other, the elongated body is inserted into the through hole. Even in the state where it is inserted, the lid member can be quickly installed without any trouble by just fitting the divided lid members from both sides of the long body, and furthermore, the two divided lid members are connected by the lid connecting part. The cover member can be connected and fixed, and the lid member can be securely fixed (corresponding to claim 6).

Further, in order to constitute the lid member, a locking projection is provided on an outer peripheral edge of the lid body so as to protrude inward along the radial direction, and the locked portion is constituted. If the locking convex portion is provided with a locking surface portion that receives the locking member on the side of the detaching direction of the lid member, in a state in which the lid member is locked to the locking portion, the locking convex portion in the detaching direction is provided. The movement can be received by the locking surface portion to prevent the detachment of the cover member, and the cover member can be securely attached in a state where the cover member does not detach along the axial direction of the through hole. When constructing a fire-resistant through-hole using
It is easy to prevent the lid member from coming off due to the thermal expansion force of the filler acting along the axial direction of the through hole (corresponding to claim 7).

[0018]

Therefore, according to the "filler support for through-hole" of the present invention, even after the long body is installed in the through-hole, it can be easily installed without any trouble. As a result, the flexibility of the installation work is improved, and the deformation due to the external force is reduced, so that the mounting stability to the structure is improved. In addition, adaptability to long bodies having different outer diameter dimensions and shapes is also improved. In addition, the provision of the lid member enables the thermal expansion of the filler particularly to effectively act on the elongated body, and the adaptability to the fireproof through hole is improved.
