Description

Construction device for granular tube attached with fireproof filler}

The present invention relates to a fireproof filler-attached standing pipe construction apparatus, and more particularly, to attach a fireproof filler to fill a penetrating gap inside a sleeve that is fixed to penetrate a wall so that the standing pipe can be constructed simply and accurately. It relates to a fireproof filler-attached granular pipe construction device.

In a multi-family house or building, such as an apartment, vertical plumbing is installed so that water for each use is transported to each floor.

In order to perform the above-mentioned facilities, when a layered floor (pipe duct) is built by pouring concrete, a hole is drilled so that the upright pipe is penetrated, and a perforated penetration part is pre-constructed.

At this time, the diameter of the penetration part should be drilled to be larger than the diameter of the pipe to be piped so that the pipe can freely enter and exit the penetration part. According to the recognition and management standards for fire-resistance structures according to the Ministry of Land, Infrastructure and Transport Notification No. 2014-200 for the above-mentioned building structures,

The fire-resistance filling structure is to prevent the spread of fire through the gap between the horizontal and vertical facility penetration joint of the fire compartment and the curtain wall and the floor. It was announced that it was legislated to be constructed according to the rules and installation standards for standards such as evacuation and fire protection structures of buildings.

According to the above, the fire-resisting filling structure that fills the gap between the inner periphery of the bottom penetration part and the outer periphery of the standing pipe, which is currently known and constructed according to the above, has fire-resistance and flame-retardant performance. After filling and inserting it into the penetration part,

In the event of a fire, the filling material is heated and foamed by the flame, which blocks the gap in the penetration part to prevent the spread of flame, smoke, and gas.

However, the fire-resistance filling structure by the conventional filler as described above is made of a flame-retardant material that does not burn easily. There is a problem in that it cannot be blocked, and when the pipe is filled with a rod-shaped filler with less flexibility and filled in the penetration part, a gap is left in the penetration part without faithfully contacting the pipe and the peripheral surface of the penetration part. In the case of a fire protection division between floors, this is the case when the fire-resistance filling structure is constructed in accordance with the criteria for determining the defects of the fire division between floors (No. 2013-930 of the Ministry of Land, Infrastructure and Transport). It is a defect in the construction, and it is difficult to precisely construct the product because it is not easy to match the thickness of the standardized filler according to the large or small gap between the pipe size and the standard of the penetration section or the degree of eccentricity of the pipe piped in the penetration section. I need a lot of this.

For the erection pipe after piping, to relieve vibration, reduce load pressure, and prevent warping, as in known construction examples, U-bolts by angle brackets are used, and they are necessarily fixedly constructed.

However, the installation structure of the sleeve, socket, and pipe for installing the fireproof filler is very complicated, and the work is difficult and very difficult. There were various problems such as wastewater flowing to the outside.
