Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a smoke curtain and system. Background Technology

[0002] In building fire protection systems, when electrical and mechanical pipelines pass through smoke curtains in their normal drooping state, a common practice is to use 10mm thick flame-retardant inorganic composite panels connected by angle irons and bolts. The panels are then hoisted and fixed to the structural floor slab using angle irons. However, holes need to be drilled at the points where the electrical and mechanical pipelines pass through to facilitate installation. This method has several disadvantages: firstly, the flame-retardant inorganic composite panels are heavy and inconvenient to install; secondly, drilling holes in the panels is difficult, affecting the construction progress of the electrical and mechanical pipelines; and thirdly, the need to drill holes in the angle irons and then fix them to the structural floor slab with screws reduces the hoisting efficiency of the flame-retardant inorganic composite panels. Utility Model Content

[0003] The purpose of this utility model is to provide a smoke curtain and system to solve the problems of inconvenient installation of flame-retardant inorganic composite panels and difficulty in making holes for electromechanical pipelines to pass through.

[0025] The present invention will now be described in detail with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0026] Please refer to Figures 1 to 4 This utility model provides a smoke curtain 100, comprising a rectangular fireproof cloth 102. An upper forming clamp 101 is fixedly disposed on the upper edge of the fireproof cloth 102, and a lower forming clamp 103 is fixedly disposed on the lower edge of the fireproof cloth 102. The upper forming clamp 101, parallel to the mounting surface, suspends the fireproof cloth 102 onto the mounting surface 200. The fireproof cloth 102 is in a hanging state due to the lower forming clamp 103. An electromechanical conduit 106 is vertically passed through the fireproof cloth 102 via an opening 104. A sewn edge 105 is provided at the edge of the fireproof cloth 102 passing through the electromechanical conduit 106. The sewn edge 105 is located on at least one side. The mounting surface 200 can be a roof ceiling or a structural beam.

[0027] Please refer to Figures 1 to 5 This utility model also provides a smoke curtain system 1, comprising multiple smoke curtains 100 suspended and aligned on the same straight line. The vertical edges of the fireproof cloth 102 between adjacent smoke curtains 100 are bonded together as a whole by fireproof cloth strips 300 with fireproof structural adhesive. The fireproof cloth strips 300 prevent gaps between the vertical edges of adjacent fireproof cloths 102, thus improving the smoke blocking effect.

[0028] The smoke curtain 100 and system 1 provided in this embodiment of the utility model use fireproof cloth 102, which is lightweight and easy for construction workers to lift and hoist onto the installation surface 200 via the upper forming clamp 101, thus improving the construction efficiency of the fireproof cloth 102 as a smoke curtain; the upper forming clamp 101 allows the fireproof cloth 102 to be hoisted into close contact with the installation surface 200; the fireproof cloth 102 is a soft material, making it easy to create holes 1 for the passage of electromechanical pipelines 106. The opening of hole 04 improves the efficiency of fireproof cloth 102 installation for electromechanical pipelines 106; the lower forming clamp 103 and the through pipe keep the fireproof cloth 102 in a hanging state; a sewn edge 105 is provided at the opening of hole 104 to facilitate the repair of the gap in hole 104 after the electromechanical pipelines 106 are installed, reduce the gap in hole 104, prevent smoke from flowing through the gap in hole 104 of the electromechanical pipelines 106, and improve the smoke blocking effect.

[0029] To improve the smoke-blocking effect, in the smoke curtain 100 and system 1 provided in this embodiment of the invention, the fireproof cloth 102 is positioned 200mm-500mm below the mounting surface 200. Specifically, when the mounting surface 200 is a suspended ceiling, the fireproof cloth 102 can be positioned 200mm below the ceiling; when the mounting surface 200 is a structural beam, the fireproof cloth 102 can be positioned 500mm below the ceiling.

[0030] In order to fix the upper and lower forming clamps 101 and 103 at the corresponding positions on the fireproof cloth 102, the smoke curtain 100 and system 1 provided in this utility model embodiment have the upper and lower forming clamps 101 and 103 respectively bonded to the upper and lower edges of the fireproof cloth 102 by adhesive.

[0031] Please refer to Figure 1 To improve the fixing effect of the upper and lower forming clamps 101 and 103 to the fireproof cloth 102, the smoke curtain 100 and system 1 provided in this embodiment of the invention have the upper and lower forming clamps 101 and 103 fixed to the upper and lower edges of the fireproof cloth 102 by multiple evenly distributed bolts 107. To improve the stability of the fireproof cloth 102 fixed to the mounting surface 200 and to improve the stability of the fireproof cloth 102 in a drooping state, the upper and lower forming clamps 101 and 103 are symmetrically distributed on both sides of the fireproof cloth 102. The upper and lower edges of the fireproof cloth 102 may have rolled edges. On the one hand, the rolled edges at the upper and lower forming clamps 101 and 103 facilitate lifting or handling by construction workers; on the other hand, the rolled edge at the upper forming clamp 101 can improve the sealing performance of the fireproof cloth 101 after installation on the mounting surface 200 through the upper forming clamp 101, avoiding gaps and improving the smoke blocking effect.

[0032] Please refer to Figure 4To secure the upper forming clamp 101 to the mounting surface 200, the fireproof cloth 102 in the smoke curtain 100 and system 1 provided in this embodiment of the invention is fixed to the mounting surface 200 by passing steel nails 108 or screws through the upper forming clamp 101. To improve the construction efficiency of fixing the steel nails 108 or screws to the mounting surface 200 through the upper forming clamp 101, both the upper and lower forming clamps 101 and 103 can be made of wood, plastic, or rubber. This eliminates the need to drill holes in the wood, plastic, or rubber before installation; the steel nails 108 or screws can be directly passed through and fixed to the mounting surface 200, thereby improving the construction efficiency of hoisting and installing the fireproof cloth 102 onto the mounting surface 200.

[0033] The smoke curtain 100 and system 1 provided in this embodiment of the present invention can improve the hoisting efficiency of fireproof cloth and the construction efficiency of electromechanical pipelines 106 passing through the fireproof cloth 102, thereby improving the overall construction efficiency of the smoke curtain 100 and system 1 with electromechanical pipelines 106 passing through it and shortening the construction cycle.
