Description of the Related Art Hitherto, there has been a structure in which piping means is penetrated through various sections such as a floor separating upper and lower layers in a multi-story building and a wall separating adjacent spaces. When such a compartment penetration part is a fireproof compartment, a structure is required so that when a fire occurs in one of the spaces partitioned by the compartment, the flame does not enter the other space.

構造とすることが多かった。FIG. 3 shows a structure around a pipe penetrating a conventional fireproof compartment. The concrete slab 1 for partitioning the upper layer and the lower layer is provided with a through hole 3 through which a pipe penetrates. Pipes 5 and 7 such as drain pipes and ventilation pipes arranged in the upper layer and similar pipes 9 arranged in the lower layer that penetrate the through holes 3 are connected to each other by a joint 11.
The pipes 5, 7, 9 and the joint 11 are made of iron, or a fire-resistant two-layer pipe product having a heat insulating two-layer structure in which an inner pipe made of a synthetic resin and an outer pipe made of a noncombustible material are combined. It was often used to prevent fires on the lower floors from being transmitted to the upper floors during a fire.

る。Next, the operation of the refractory compartment penetration processing structure configured as described above will be described. In the present structure configured as shown in FIG. 1, the concrete slab 21 is penetrated by the piping means including the pipes 33, 35, the joint 25, and the integrated pipe 26. Therefore, the concrete slab 21 is sandwiched between the upper layer space and the lower layer. Fluid circulation such as drainage and ventilation is secured between spaces. Here, when a fire occurs, the heat-expandable sheet 37 is heated by the heat of the fire on the lower floor side.
Expands to promote the blockage of the pipe, so that the space through which the piping means passes in the through hole 23 can be blocked. Therefore, for example, even if a fire occurs in the lower space and the heat causes the integrated pipe 26 made of synthetic resin to contract, resulting in incomplete blockage, the heat-expandable sheet 37 expands. Since the blockage of the integrated pipe is promoted, the space where the integrated pipe 26 is disposed is blocked, and the flame can be prevented from propagating to the upper layer through the space. Further, since the refractory material 39 such as mortar fills the space between the heat-expandable sheet 37 and the concrete slab 21, the structure prevents the flame from propagating from one space above and below to the other space. is doing.

When 3 (R / t) 1/2 / A> X, the heat-expandable sheet 37 is too thin, so that the pipe line blocking effect is not sufficient, and conversely X <6 (R / t) 1/2. In the case of / A, there is a problem that the cost is too high because the heat-expandable sheet 37 is thicker than necessary, but in the present invention, the thickness of the heat-expandable sheet 37 is set as described above. As a result, it is possible to achieve cost reduction and weight reduction while being able to obtain a sufficient pipe line blocking effect.
In addition, concretely, as a vinyl chloride pipe, JIS
K6741 “Rigid Vinyl Chloride Pipe” and JIS K6739
When a 2-hour heating test based on ISO 834 was performed using a nominal diameter of "drainage hard vinyl chloride pipe joint" of 100, the following test results were obtained. In the test, the structure of the example of the present application (sheet 2 mm wound product) coated with the heat-expandable sheet having a thickness within the range of the above-described conditions, and the heat-expandable sheet having a thickness outside the range of the condition are coated. The comparison was performed with the structure of the comparative example (sheet 1 mm wound product). First, about 2 minutes after the start of heating, foaming of the heat-expandable sheet started in both Examples and Comparative Examples.
Five minutes after the start of heating, the vinyl chloride pipe in the heating side space started to fall off in both the example and the comparative example. Further, after 13 minutes from the start of heating, in the comparative example, the vinyl chloride pipe in the heating side space almost fell off. On the other hand, in the example, the vinyl chloride pipe was blocked by the foaming action of the heat-expandable sheet. Furthermore, in the comparative example, after 69 minutes from the start of heating, smoke was generated from the vinyl chloride pipe and the vicinity of the mortar portion, and 72 minutes later,
The amount of smoke started to increase gradually, and after 112 minutes,
Smoke was violently ejected from each joint of the vinyl chloride pipe. On the other hand, in the example, even after 120 minutes from the start of heating, no abnormality was observed after the vinyl chloride pipe was blocked by the heat-expandable sheet. As described above, in the fireproof compartment penetrating structure covered with the heat-expandable sheet having the preferable thickness of the present invention, it is possible to secure a sufficient pipe line closing effect.

There is no need to use iron or a fireproof double-layer pipe structure.
Due to this, in the present embodiment, since the pipes 33, 35 and the joint 25 all have a single-layer pipe structure made of synthetic resin, they are excellent in chemical resistance, corrosion resistance, and inner surface smoothness,
In addition, due to its light weight, it has excellent workability and is superior in terms of cost compared to steel and fire-resistant double-layer pipe structures. Therefore, in the fireproof compartment penetration treatment structure of the present embodiment, in addition to the weight reduction and cost reduction of the heat-expandable sheet itself, the weight reduction and cost reduction of the piping means itself are also achieved. Overall, weight reduction and cost reduction have been realized.

The fireproof compartment penetration processing structure of the present embodiment is the same as the structure according to the first embodiment described above, except for the covering aspect of the heat-expandable sheet. A heat-expandable sheet 137 having a thickness similar to that of the heat-expandable sheet 37 in the first embodiment is annularly formed on the outer periphery of the portion of the integrated pipe 26 located in the through hole 23. It is covered. The upper end 137a of the heat-expandable sheet 137 has a dimension D (preferably 20 m) from the upper surface of the concrete slab 21.
(about m to 50 mm) ends at a position located below. That is, the outer peripheral surface of the joint 25 in the through hole 23 has a portion not covered by the height dimension D. In the fire protection compartment penetration processing structure according to the second embodiment, in addition to the effect of the fire protection compartment penetration processing structure according to the first embodiment, the effect of blocking the passage of smoke at the time of fire is It is higher than that of the first embodiment. That is, since the refractory material 39 such as mortar is directly connected to the upper part of the pipe 26 without the heat-expandable sheet 137 in the upper part (the range of the dimension D) in the through hole 23, the heat-expandable property is increased in the case of fire. Even when the sheet 137 is foamed by heating and follows the deformation of the vinyl chloride pipe, a gap is formed between the heat-expandable sheet 137 and the refractory material 39, and this prevents the generation of smoke as an airway. It is possible. The uncovered portion of the outer peripheral surface of the piping means in the through hole 23 is not limited to the upper surface side of the concrete slab and may be set on the lower surface side.
