New description: [New technical field] The original creation department involves a type of building plastic pipe. [Prior Art] A device used for fire safety, especially for the interception of cable cutters for cable lines. Fire extension device. Regardless of the form of the building, there will be plastic members of the pipe fittings and lines, such as water pipes, pipes, wire pipes, etc. These pipes often pass through walls, floors or pipes to place their equipment. The space where the functional contents are delivered. However, when a building fires, the flame and smoke cannot quickly break through the fire wall and the floor, but the fire can quickly spread to other parts through the above-mentioned open pipe fittings or pipelines. The space, which in turn produces the pipe smoke: the effect 'and the fire quickly expands; therefore, the fireproof packing between the pipe of the pipe through the wall of the building and the floor pipe is a very important part of the fire prevention of the building. The heat-expandable foam is installed between the pipe fittings, the pipe edge and the opening of the wall or the floor. Therefore, when the fire occurs, the thermal expansion foam contacts the high temperature, and the expansion expands irregularly toward the softened plastic. The pipe member is pressed inwardly, and the pipe member is blocked and closed, so that it is difficult for the fire heel to pass through the pipe member to achieve the ideal purpose of preventing the burning. When the thermal expansion foam is installed, it is installed after the slab and the wall are completed. For example, when the slab is built, a tubular phantom is placed vertically on the slab, and then the concrete is poured on the slab. On the mold, after the concrete is dried and solidified, the plate mold and the tubular mold body can be removed to obtain a '匕 concrete floor slab' and the concrete slab is formed at the corresponding tubular mold body, and the opening is in the upper and lower sides. The ends communicate with each other, and thereby the various pieces of equipment and pipelines can be passed through. Then the outer wall of the pipe is sleeved and fixed with the aforementioned thermal expansion foam ' and the thermal expansion foam is located in the opening of the concrete floor Then, fill in appropriate materials, such as concrete or refractory materials, to fill the openings, and the device is completed. However, the pipe fittings in the openings of the concrete slab may be too complicated and complicated, so it is difficult to accurately reserve The size of the opening, the aperture of the opening is often reserved for a small distance; however, the reserved distance also causes the gap between the inner wall surface of the opening and the pipeline and the thermal expansion foam to be too large, because It is necessary to fill in the gap as described in the following, and the filling operation causes troubles in construction, which is time consuming and laborious; in addition, even if the aperture of the opening is much larger than the outer diameter of the thermally expanded foam, However, if the object is to be installed in the opening, it is bound to be restricted by the wall of the hole and it is difficult to install. Moreover, the prior art thermal expansion foam has no seal and moisture proof design, so the moon b can be used because of the party lake. The fire retarding effect is not good, and the long-term application of financial property is affected. [New content] In order to achieve the above-mentioned creative purpose, the technical means adopted in this creation is to design a pre-buried building fire-blocking tube fire-retardant and burn-out device.

The advantage of this creation is that when the floor or wall is constructed, the creation can be directly fixed on the form to replace the prior art tubular body, and then When poured on the formwork, the heat-expandable foam is covered together, so that when the floor or wall is poured, only the formwork needs to be removed, and the concrete is not only connected by the externally connected sleeve. Similarly, the pipeline can be passed through the 'heat-expandable foam outside the sleeve and also installed in the concrete to achieve the pre-embedded fire retarding effect; in addition, since the thermal expansion foam is installed outside the sleeve, Therefore, there is no need to reserve space in the sleeve to install the thermal expansion foam, so that the design can be designed into various specifications with different inner diameters, and when installed, the outer diameter of the pipeline can be matched with appropriate specifications. This creation can effectively reduce the gap between the pipeline and the sleeve, thereby eliminating the need to fill the gap and saving a lot of manpower and time. This creation achieves the purpose of facilitating the installation of the thermal expansion foam. In addition, when a fire occurs, 'the thermal expansion foam will rapidly expand to squeeze the pipe sleeve and the pipeline in it' and the pipe casing and pipeline will be blocked and closed, thereby blocking the fire and smoke, so as to achieve the building fire protection regulations. The requirement of the step-in-step, the pre-buried building wears a fire tube sleeve fire retardant and fire-extinguishing device, wherein the single heat-expandable foam body and the U-core 1 are dry, and the heat-expandable foam body is adjacent to the sleeve Set the flange ring to open the scorpion to the flange ring. Or the 'pre-buried building cut-off pipe sleeve fire retardant has two heat-expandable foams and two " U-pieces, and the two-expansion expansion foams are respectively adjacent to the two ends of the sleeve The opening, ... ^ again, the thermal expansion foam abuts against the flange ring of the official sleeve; the two fixed expansion foams. + knife set - the two heats M443260 further = the above-mentioned pre-buried building fire interception pipe sleeve fire retardant, set, wherein the flange ring of the official sleeve is axially formed with at least one fixing hole.

Belt, thermal expansion foam and sleeve. Step-by-step [the pre-buried building wearing fire tube sleeve is fire-retardant, wherein each fixing member comprises a ring-shaped purple belt and -", the ring-shaped belt is wrapped around the corresponding heat-expandable foam ; banding around, looping #扎带, and pressing the ring-shaped cable ties 'thermal expansion foam and sleeve. Further, in the pre-embedded building, the fire tube sleeve fire-retarding and extruding device, wherein the ring-shaped cable ties of the fixing members are respectively axially at both ends thereof and radially extending from the plurality of end-stop ring sheets The spacer ring is disposed around the spacer and abuts against the corresponding thermal expansion foam. Further, the pre-buried building fire-blocking pipe sleeve is fire-retardant and has a pipe diameter of 8 cm to 63 cm. In the case of the step-by-step, the pre-embedded building wears a fire tube sleeve fire retardant device, wherein the step further comprises a moisture barrier layer, the moisture barrier layer is tightly sleeved: an official sleeve, a thermal expansion foam and a fixing member outer. In this way, the moisture-proof effect can be further achieved to avoid failure of the thermal expansion foam in the event of moisture.
