Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filler support for a through hole for supporting a filler filled between a through hole provided in a structure and an elongated body inserted in the through hole. Regarding the ingredients.

[0002]

2. Description of the Related Art Conventionally, as a filling material supporter for a through hole of this kind, one frame member which can be locked in an inner fitting state is provided in one through hole, and a bottom member is provided in the frame member. A through space for inserting a long body in the inner space of the frame member is formed in one section, and a filling material can be filled between the long body inserted in the space and the frame member to be supported. There was something that was formed.

[0003]

There are various types of elongated members that penetrate the structure, such as a refrigerant pipe provided with a flammable heat insulating coating layer on the outer peripheral portion and a fire resistant structure. There are water supply and drainage pipes made of steel pipes alone, and when these multiple types of long bodies are respectively penetrated into the structure consisting of slabs, partition walls, etc., in order to prevent mutual combustion between the two spaces partitioned by the structure In the refrigerant pipe, by filling the periphery of the penetrating portion of the pipe with a filler made of flame-retardant thermal expansion putty, it is possible to reliably pack the periphery of the pipe by the expanded filler even if a fire occurs, In the water supply / drainage pipe, the circumference of the penetrating portion of the pipe is filled with a filling material made of mortar which is inexpensive and has a small volume change due to fire.
In addition, it is rare that the elongate bodies penetrate through the through holes at the same time, and in general, the long bodies are often installed at different times. In addition, a long body that was not originally planned may be added and installed afterwards.

According to the conventional through hole filling material support, when a plurality of elongated bodies are inserted into the elongated body insertion through space, each elongated body is located in the same through space (compartment). Therefore, each elongated body is supported by the same filler in the same supporting state. However, as mentioned above,
In order to penetrate multiple types of long bodies that need to have different support states or long bodies with different installation times into the structure, install multiple through holes in the structure and Since it is necessary to sort and insert the long bodies having the same support state into each other, it is troublesome to install a plurality of through-holes, and there is a risk that the long body installation efficiency may decrease and the structure Since the through holes are dispersedly arranged in the body, there is a problem that a large through space is needed and the space is taken up.

As a means for solving such a problem,
It is conceivable that the frame member is provided with a partition portion for dividing the through space for inserting the elongated body into a plurality of parts. However, since a long body of the same type and size (outer diameter) is not always inserted into each through space defined by the partition section, there are several types of filling formed with different partition intervals. It is necessary to prepare a material support tool, the number of products will increase, and if mass production is assumed,
There is a problem of increased costs.

Therefore, an object of the present invention is to solve the above-mentioned problems and to allow a plurality of types of elongated bodies having different supporting states to be inserted and supported in the through holes of the structure in the respective supporting states. An object of the present invention is to provide a highly versatile filling material support tool for through-holes, which can cope with various elongated body arrangement situations.

[0007]

To achieve this object, the through hole filling material support of the present invention is characterized in that a support frame integrally attachable to the structure is provided, and the structure is provided in the structure. In the inner space of the provided long body insertion through hole, a support plate capable of supporting a filling material filled between the long body inserted into the through hole is detachably attached to the support frame. And a partition plate that can freely partition the through hole in the radial direction.
The support frame is slidably mounted along the radial direction of the through hole.

Even if the support plate is divided and formed so as to sandwich the insertion portion of the elongated body, and further, the support frame is provided with an engaging portion with the structure. Good.

[0009]

According to the characteristic structure of the filling material supporter for the through hole of the present invention, a support frame that can be integrally attached to the structure is provided, and the filling material can be supported in the inner space of the through hole. Since the support plate is detachably attached to the support frame and the partition plate that partitions the through hole in the radial direction is provided, the partition plate is provided inside the through hole of the structure to which the support frame is attached. With this, it becomes possible to partition into a plurality of through spaces for inserting long bodies, and it becomes possible to individually carry out the insertion setting work of each long body to be inserted into these partitioned spaces. Even if the body is inserted and installed at different times, it is possible to proceed with the insertion and installation work without adversely affecting other installed long bodies, and further, to install multiple long bodies of different types. After installing in the penetration space, part Even when the type of that replacing only long body, it is possible to proceed by itself without affecting the long body of other kinds.

Further, the structure is provided with only one through-hole in which the spaces for inserting the long bodies are provided, and a plurality of long bodies of different types as described above can be used in a state suitable for the site situation. It can be inserted and installed in each different insertion space, and as a result, it is possible to reduce the installation labor of the through hole and save space.

Since the partition plate is slidably attached to the support frame along the radial direction of the through hole, the size, number, and shape of each elongated body to be inserted into the through hole.・ The partition space can be freely changed according to the arrangement, etc., and the limited space of the through hole can be used as a long body insertion through space to match the site situation more efficiently. It is possible to use them properly. Therefore, compared with the one in which the partition plate is fixed at a predetermined position, the flexibility of inserting the long body is improved,
It can be used as a filler support with high versatility, and as a result, it is possible to use it as a dual-purpose filler support without preparing different types of filler supports with different partitioning intervals, thus achieving cost reduction in mass production. be able to.

Further, for example, when a putty-like material is used as the filling material, the partition plate is slid to the side retracted from the putty filling portion, and the putty filling work is performed in a state where a wide working space is secured. After that, a filling method of sliding the partition plate to the original position can be adopted, and thus the work efficiency of filling the through hole with the filling material can be improved.

If the support plate is divided and formed so as to sandwich the insertion portion of the elongated body, the division can be made compact and easy to install.
The support plate can be installed around the long body even after the long body is inserted into each long body insertion through space, and the flexibility of the work can be improved.

Furthermore, if the support frame is provided with an engaging portion with the structure, the support frame can be installed in a state of engaging with the structure, and the support frame and the structure can be provided. Can be bound more strongly. As a result, for example, even if a fire occurs and heat is applied to the support frame, it is possible to make it difficult for the support frame to be deformed independently, and prevent a gap through which smoke or flame can pass from the structure. Therefore, it is possible to form a more reliable fireproof penetration portion.

[0015]

As described above, according to the filler supporter for the through hole of the present invention, the through hole of the structure can be easily partitioned in various partitioning conditions, so that the versatility of the filler supporter can be improved. And at the same time, it is possible to reduce the cost of the product. It is also possible to insert and support a plurality of different types of elongated bodies in the respective sections of the through-holes of the structure in an individually supported state and with good work efficiency, thus saving the through-space and increasing the length of the elongated body. It is possible to improve the efficiency of the insertion installation work and the filling work of the filling material, and the maintainability after the insertion.
