Description

Technical Field

[0001] This utility model relates to the technical field of wall structure, and in particular to an integrated fireproof and soundproof prefabricated railing. Background Technology

[0002] In modern architectural design, to meet the requirements for fire protection, safety, and sound insulation, especially in the design of floor-to-ceiling windows and balconies in high-rise residential and commercial buildings, firewalls and protective railings are usually required. Traditional construction methods use brick masonry to meet fire protection requirements and use materials such as metal or glass as protective railings to provide the necessary physical barrier.

[0003] Currently, while the method of forming fireproof partitions by laying bricks on-site can effectively prevent the spread of fire, the construction process is complex, time-consuming, and the large amount of bricks used not only increases the cost of building materials but also occupies a large amount of indoor space. Utility Model Content

[0004] To simplify the construction of prefabricated railings, this utility model provides an integrated fireproof and soundproof prefabricated railing.

[0005] This utility model provides an integrated fireproof and soundproof assembled railing, which adopts the following technical solution: An integrated fireproof and soundproof prefabricated railing includes a cement fiberboard, uprights, crossbars, a first connecting piece, and a second connecting piece. The cement fiberboard is arranged in a box-shaped structure, and multiple uprights are arranged inside the cement fiberboard. The bottom end of the upright is fixedly connected to the first connecting piece, and the first connecting piece is fixedly connected to the concrete base by means of screws and nuts; Multiple crossbars are provided along the axial direction of the upright. The crossbars are fixedly connected to the upright. Both ends of the crossbars are fixedly connected to the second connecting pieces. Two adjacent cement fiberboards are fixedly connected by the second connecting pieces between the crossbars. Two adjacent second connecting pieces are fixed by screws and nuts. The inner cavity of the cement fiberboard is filled with a foamed core layer.

[0006] Preferably, the crossbar has multiple threaded holes at both ends, and the second connecting piece is fixedly connected to the crossbar through the threaded holes.

[0007] Preferably, an extension plate is provided between two adjacent cement fiberboards to seal both ends of the cement fiberboard. The extension plate has a slot for placing the second connecting piece.

[0008] Preferably, the extension plate is further provided with a plurality of fixing plates, the fixing plates abutting against the inner end of the cement fiberboard, and the extension plate is fixedly connected to the cement fiberboard through the fixing plates.

[0009] Preferably, the extension plate has multiple fixing holes, which are connected to the placement groove.

[0010] Preferably, a third connecting piece is fixedly installed at the bottom end of the upright, the two ends of the third connecting piece are set at a certain angle, one end of the third connecting piece is fixedly connected to the upright by bolts, and the other end of the third connecting piece is fixedly connected to the concrete base by multiple bolts.

[0011] Preferably, the surfaces of the first connecting piece, the second connecting piece, and the third connecting piece are all coated with an anti-rust layer.

[0012] Preferably, the foamed core layer is polyurethane foam.

[0013] In summary, this utility model has at least one of the following beneficial technical effects: 1. This design integrates fireproofing and sound insulation, replacing traditional multi-material stacking. All components can be prefabricated in the factory and connected on-site with bolts, ensuring rapid, clean, and quality-controlled construction. The internal uprights and crossbars form a robust framework, greatly enhancing the overall rigidity and impact resistance of the balustrade, providing superior safety compared to pure masonry structures. The continuously filled foam core layer eliminates sound and cold bridges, ensuring the integrity and stability of sound insulation and fireproofing performance. The design of the crossbars and second connecting pieces enables convenient and reliable connection between multiple balustrade units, adapting to the needs of balustrades of varying lengths.

[0014] 2. The extension plate seals the seams between units, making the appearance more complete and aesthetically pleasing, while preventing the internal structure from being exposed. It effectively seals the seams, prevents the foam core layer from being exposed, and further improves the sound insulation and fire resistance of this node, preventing it from becoming a performance bottleneck.

[0015] 3. By more effectively transferring and distributing the vertical force of the uprights to the base, the ability of the parapet to resist horizontal thrust is greatly enhanced, preventing the base from being pulled out or torn, resulting in a higher safety factor. The increased connection area reduces localized pressure on the concrete base, making the connection more reliable. Attached Figure Description

[0023] Example 1: This utility model discloses an integrated fireproof and soundproof prefabricated railing. (Refer to...) Figures 1 to 6 An integrated fireproof and soundproof prefabricated railing mainly includes a cement fiber board 101, uprights 102, crossbars 103, a first connecting piece 201, and a second connecting piece 202. The cement fiber board 101 is box-shaped, and multiple uprights 102 are arranged inside the cement fiber board 101. The bottom end of the upright 102 is fixedly connected to the first connecting piece 201, and the first connecting piece 201 is fixedly connected to the concrete base by screws and nuts. Multiple crossbars 103 are arranged along the axial direction of the uprights 102. The crossbars 103 are fixedly connected to the uprights 102, and both ends of the crossbars 103 are fixedly connected to the second connecting pieces 202. Adjacent cement fiber boards 101 are fixedly connected by the second connecting pieces 202 between the crossbars 103, and adjacent second connecting pieces 202 are fixed by screws and nuts. The inner cavity of the cement fiber board 101 is filled with a foamed core layer 300.

[0024] Cement fiberboard 101 inherently possesses fire-resistant properties. Its box-type structure provides space for the foamed core layer 300, achieving integrated fire resistance and sound insulation, replacing traditional multi-material stacking. All components can be prefabricated in the factory and connected on-site with bolts, ensuring rapid, clean, and quality-controlled construction. The internal uprights 102 and horizontal bars 103 form a robust framework, significantly enhancing the overall rigidity and impact resistance of the balustrade, providing superior safety compared to pure masonry structures. The continuous, seamless, and corner-free foamed core layer 300 eliminates sound and cold bridges, guaranteeing the integrity and stability of sound insulation and fire resistance. The design of the horizontal bars 103 and the second connecting piece 202 enables convenient and reliable connection between multiple balustrade units, adapting to the needs of balustrades of varying lengths.

[0025] Reference Figure 4 and Figure 6 In some embodiments, the crossbar 103 has multiple threaded holes 104 at both ends. The second connecting piece 202 is fixedly connected to the crossbar 103 through the threaded holes 104. The second connecting piece 202 can be fixedly assembled using bolts by selecting the corresponding threaded hole 104 according to the assembly length requirements. This allows for fine-tuning during installation, compensating for dimensional errors in civil construction and improving the adaptability and success rate of installation. The threaded connection method is robust and reliable, ensuring the effectiveness of force transmission between adjacent units.

[0026] Reference Figures 1 to 3 In some embodiments, an extension plate 105 is also provided between two adjacent cement fiberboards 101. The extension plate 105 seals both ends of the cement fiberboard 101, and has a placement groove 106 for placing the second connecting piece 202. The extension plate 105 seals the joint between units, making the appearance more complete and aesthetically pleasing, while preventing the internal structure from being exposed. It effectively seals the joint, prevents the foamed core layer 300 from being exposed, and further improves the sound insulation and fire resistance of the node, avoiding it becoming a performance bottleneck.

[0027] Reference Figure 3 In some embodiments, a third connecting piece 203 is fixedly installed at the bottom of the upright 102. The two ends of the third connecting piece 203 are set at right angles. One end of the third connecting piece 203 is fixedly connected to the upright 102 by bolts, and the other end of the third connecting piece 203 is fixedly connected to the concrete base by multiple bolts. The angled design more effectively transmits and distributes the vertical force of the upright 102 to the base, greatly enhancing the ability of the parapet to resist horizontal thrust, preventing the root from being pulled out or torn, and thus increasing the safety factor. It also increases the connection area, reduces local pressure on the concrete base, and makes the connection more reliable.

[0028] In some embodiments, the surfaces of the first connecting piece 201, the second connecting piece 202, and the third connecting piece 203 are all coated with an anti-rust layer. Connectors are crucial for ensuring structural safety; anti-rust treatments, such as hot-dip galvanizing, significantly improve their corrosion resistance, extend the service life of the railing in outdoor environments, and ensure long-term safety.

[0029] In some embodiments, the foamed core layer 300 is polyurethane foam. Polyurethane foam has excellent sound insulation properties, good fire resistance and flame retardancy, strong adhesion, can be firmly bonded to cement fiberboard 101 and internal skeleton to form a composite structure, and is lightweight.

[0030] Example 2: This utility model discloses an integrated fireproof and soundproof prefabricated railing. (Refer to...) Figure 3An integrated fireproof and soundproof prefabricated railing mainly includes an extension plate 105 with multiple fixing plates 107. The fixing plates 107 abut against the inner end of the cement fiberboard 101, and the extension plate 105 is fixedly connected to the cement fiberboard 101 through the fixing plates 107. The abutment between the fixing plates 107 and the inner end of the cement fiberboard 101 forms a "clamping" or "supporting" effect, making the installation of the extension plate 105 more stable and less prone to falling off.

[0031] Reference Figure 3 and Figure 6 In some embodiments, the extension plate 105 has multiple fixing holes 108, which communicate with the placement groove 106. Through the fixing holes 108, a screwdriver can be passed through the fixing holes 108 to insert and fix two overlapping second connecting pieces 202 using a tapered screw, making the fixing connection method more convenient; at the same time, after fixing, protective glue can be filled into the fixing holes 108 for sealing to improve aesthetics.

[0032] The implementation principle of the integrated fireproof and soundproof prefabricated railing of this utility model embodiment is as follows: The system utilizes prefabricated box-type cement fiberboard 101 and an internal steel frame composed of crossbars 103 and uprights 102, with a continuous polyurethane foam core layer 300 filling the cavity. This composite structure not only provides excellent sound insulation and fire resistance but also solves the problems of cracking and weak points in the parapet structure. It achieves rapid, clean, and quality-controlled construction. Furthermore, the precise connector system ensures convenient connections between units and extremely high safety and durability of the overall structure.

[0033] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
