Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and in particular to a fire arrestor ring that can be quickly assembled. Background Technology

[0002] Fire collars are safety devices used to prevent the spread of fire. They are generally made of metal with a flame-retardant expanding core material inside. They are fitted over the outer wall of rigid polyvinyl chloride (PVC) pipes and fixed to the floor or wall. When a fire occurs, the core material expands rapidly due to heat, squeezing the UPVC pipe and sealing the pipe opening in a short time, preventing the fire from spreading along the opening.

[0003] The main construction method for installing existing fireproof collars is to attach the fireproof collar to the riser, drill holes in the bottom of the floor slab, and fix it to the floor slab with expansion bolts. This installation method is cumbersome, especially in narrow spaces, and has low overall installation efficiency. In addition, drilling holes will damage the floor slab. To solve this problem, we have researched a fireproof collar that can be assembled quickly. Utility Model Content

[0013] The following will describe specific embodiments and appendices. Figure 1-2 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0014] A fire-resistant ring that can be quickly assembled includes a water-stop section 1, which is a cylindrical ring with a through hole in the center for inserting pipes. A connecting ring 11 is fixedly connected to the bottom end of the water-stop section 1, protruding radially outward. Four fixing ears 12 are equidistantly arranged along the outer circumference of the connecting ring 11. Each fixing ear 12 has a pre-embedded bolt 13 fixedly connected to its upper side. In actual use, the entire water-stop section 1 needs to be poured into the floor slab concrete. The through hole on the water-stop section 1 allows for holes to be left in the poured floor slab for pipes to pass through. A fire-resistant ring 2 is provided on one side of the water-stop section 1, and is assembled and connected to the water-stop section 1. Several connecting ears 26 are provided on the outer side of the fire-resistant ring 2 corresponding to the fixing ears 12. The connecting ears 26 are detachably connected to the fixing ears 12, enabling the fire-resistant ring 2 to be quickly assembled and connected to the water-stop section 1.

[0015] The pre-embedded bolt 13 is fixedly connected to the top side of the fixing ear 12. The pre-embedded bolt 13 includes a metal rod 131, which is cylindrical in shape. The metal rod 131 is fixedly connected to the top surface of the fixing ear 12. Two externally protruding rings 132 are fixedly connected to the metal rod 131. The externally protruding rings 132 are annular and are sleeved and fixedly connected to the metal rod 131. One externally protruding ring 132 is fixedly connected to the upper part of the middle of the metal rod 131, and the other externally protruding ring 132 is fixedly connected to the upper part of the metal rod 131. The metal rod 131 and the externally protruding rings... 132 is cast into the concrete floor slab together, which makes the connection between the entire waterstop joint 1 and the concrete more stable. A threaded hole 133 is opened inside the metal rod 131. The threaded hole 133 passes through the fixing lug 12 from bottom to top but does not pass through the metal rod 131. The threaded hole 133 is a stepped hole. A plastic plug 134 is detachably connected inside the threaded hole 133. The plastic plug 134 is inserted into the threaded hole 133. During the pouring of concrete, it can prevent foreign objects from entering the threaded hole 133 and affecting its subsequent connection with the bolt, ensuring the smooth flow of the internal threads.

[0016] The fixing lug 12 has a fixing hole 14, which can be used to fix the waterstop 1 to the template by means of nails or other devices. The connecting lug 26 of the fireproof ring 2 has a connecting hole 27 corresponding to the threaded hole 133. Later, the fireproof ring 2 can be quickly fixed to the pipe inserted into the waterstop 1 by bolts passing through the connecting hole 27 and threaded into the threaded hole 133. The fixing lug 12 and the connecting lug 26 are detachably connected by fixing bolts.

[0017] The fireproof ring 2 includes two semi-circular shells, namely a negative shell 21 and a positive shell 22. Both ends of the negative shell 21 are provided with connecting buckles 23, and both ends of the positive shell 22 are provided with locking plates 24. The connecting buckles 23 and the locking plates 24 are connected in cooperation. The connection port and the locking plates 24 are existing technologies and can be plugged in. The inner ring of the negative shell 21 and the positive shell 22 is provided with a flame-retardant ring 25. The flame-retardant ring 25 is existing technology. When it is exposed to high temperature and open flame, it expands rapidly when heated and can squeeze the pipe, seal the pipe in a short time, and prevent the fire from spreading through the pipe.

[0018] Usage: First, before pouring the concrete for the floor slab, the waterstop joint 1 needs to be fixedly connected to the floor slab formwork through the fixing hole 14. Then, the concrete is poured. After the concrete solidifies, it will wrap around the waterstop joint 1. Then, pipes are inserted into the upper and lower ends of the waterstop joint 1, which allows the pipes on the upper and lower floors of the floor slab to be interconnected through the waterstop joint 1. A waterstop ring is placed on the upper pipe to further prevent water from seeping into the gap. Then, the male shell 22 and female shell 21 are fitted onto the pipe below the waterstop joint 1. Then, the fixing bolts are used to connect the fireproof ring 2 to the threaded hole 133 of the fixing ear 12 through the connecting hole 27. This will firmly connect the fireproof ring 2 to the waterstop joint 1. No drilling is required, and the installation is convenient and simple.
