Description

Technical Field

[0001] This utility model belongs to the field of building decoration technology, and in particular relates to a structure of a window sill plate for fireproofing between curtain wall layers. Background Technology

[0002] In modern architecture, curtain wall structures, as a widely used form of exterior wall, not only offer excellent decorative effects but also provide certain functions such as heat insulation, waterproofing, and energy conservation. However, in high-rise buildings, fire prevention is particularly important, and inter-floor fire-resistant construction is crucial for preventing the vertical spread of fire.

[0003] In traditional inter-layer fire-resistant curtain wall construction, window sills are often supported by the curtain wall structure. This design requires connecting structures on the curtain wall structure to fix the window sills, which brings several significant problems. First, the weight of the window sills and connecting structures increases the burden on the curtain wall structure, potentially leading to deformation or damage, affecting its overall stability and safety. Second, the connecting structures occupy considerable space, making the curtain wall structure more complex, reducing the installation space for materials, and limiting the selection of fire-resistant materials and construction methods. Utility Model Content

[0004] In view of the shortcomings of the related technologies, this utility model provides a window sill structure for fireproofing between curtain wall layers, so as to solve the problem that the curtain wall structure is prone to deformation and damage when bearing too much load.

[0005] This utility model provides a window sill structure for fireproofing between curtain wall layers, including a building wall and a building curtain wall located on the outside of the building wall;

[0006] An embedded plate is installed on the outer end of the building wall. The embedded plate is L-shaped and extends from the top surface of the building wall to its outer end. A window sill support is installed on the embedded plate. A base fire-retardant board is fixedly installed on the top surface and the rear end of the window sill support. A window sill decorative board is laid on the base fire-retardant board.

[0007] The building curtain wall has horizontally arranged transverse ribs, and the inner end face of the transverse ribs is fitted with the outer end face of the corresponding window sill decorative panel with a gap, and a foam rod is installed between the two.

[0008] Flame-retardant mounting brackets are installed between the horizontal ribs of the curtain wall and the embedded plate. There are two flame-retardant mounting brackets, and there is a space between the two flame-retardant mounting brackets. Rock wool is installed in the space.

[0009] In some embodiments, the embedded plate has a vertically arranged first plate and a horizontally arranged second plate. The first plate is attached to the outer end face of the building wall and fixedly connected to it by a first expansion bolt, and the second plate is attached to the top surface of the building wall and fixedly connected to it by a second expansion bolt.

[0010] In some embodiments, the window sill support includes a vertically arranged support beam and a horizontally arranged cantilever beam. The top end of the support beam is fixedly connected to the inner end of the cantilever beam to make the window sill support L-shaped. The bottom end of the support beam is fixedly connected to the corner bracket fixedly welded to the rear of the top surface of the embedded plate.

[0011] In some embodiments, an inclined bracing beam is fixedly installed between the bottom of the embedded plate and the outer end of the cantilever beam.

[0012] In some embodiments, the cantilever beam, support beam, and diagonal brace are all made of galvanized steel pipe.

[0013] In some embodiments, the two flame-retardant mounting brackets are a first mounting bracket and a second mounting bracket, respectively.

[0014] The first mounting bracket includes a first suspension plate, a support plate, and a first connecting plate. The first suspension plate is vertically arranged, with its top end connected to the horizontal rib of the curtain wall and its bottom end connected to the outer end of the support plate. The support plate is horizontally arranged, with its rear end connected to the top end of the first connecting plate. The first connecting plate is vertically arranged, attached to the outer surface of the embedded plate, and fixedly connected to it.

[0015] The second mounting bracket includes a second suspension plate and a second connecting plate. The second suspension plate is vertically arranged, with its top end connected to the horizontal rib of the curtain wall and its bottom end connected to the outer end of the second connecting plate. The second connecting plate is horizontally arranged, with its rear end attached to the top surface of the embedded plate and fixedly connected to it.

[0016] The accommodating space is located between the support plate and the second connecting plate.

[0017] In some embodiments, the first suspension plate and the second suspension plate are stacked sequentially from the inside out, and their top ends are fixedly connected to the horizontal ribs of the curtain wall by the same fixing bolt.

[0018] In some embodiments, the bottom of the embedded plate is fixedly connected to the outer end face of the building wall by a first expansion bolt, and the first connecting plate is fixedly connected to the bottom of the embedded plate by a first expansion bolt.

[0019] The top of the embedded plate is fixedly connected to the top surface of the building wall by a second expansion bolt, and the second connecting plate is fixedly connected to the top of the embedded plate by a second expansion bolt.

[0020] In some embodiments, rock wool fills the accommodating space so that its rear end is attached to the outer surface of the embedded plate.

[0021] Based on the above technical solution, in this embodiment of the utility model, an embedded plate is installed on the building wall to fix the window sill support base, and a window sill decorative panel is installed on the window sill support base to form a window sill structure. The window sill decorative panel is supported by the building wall through the window sill support base. The window sill decorative panel and the window sill support base are not connected to the building curtain wall, which reduces the load on the building curtain wall, prevents the curtain wall structure from deforming or being damaged due to excessive load, and improves the structural stability and safety. A connection space is left on the horizontal ribs of the curtain wall structure for the flame-retardant mounting bracket, which is convenient for the installation of the flame-retardant mounting bracket. The flame-retardant mounting bracket is fixed by the embedded plate and the horizontal ribs of the curtain wall, and rock wool is installed in the space between the two flame-retardant mounting brackets. The rock wool is supported by both the building wall and the curtain wall structure, which makes it more stable. The two flame-retardant mounting brackets are located in a large space between the embedded plate and the horizontal ribs of the curtain wall, and their shapes have a large degree of freedom. Thus, the corresponding accommodating space can be formed according to the shape of the rock wool, which improves the freedom of fireproof material selection and solves the problem that the curtain wall structure is prone to deformation and damage when subjected to excessive load in the interlayer fireproof construction of the curtain wall.

[0036] like Figures 1 to 2 As shown, in one schematic embodiment of the fire-resistant window sill structure of the interlayer curtain wall of this utility model, the fire-resistant window sill structure of the interlayer curtain wall includes a building wall 1 and a building curtain wall 2 located outside the building wall 1.

[0037] An embedded plate 3 is installed on the outer end of the building wall 1. The embedded plate 3 is L-shaped and extends from the top surface of the building wall 1 to its outer end face. A window sill support 4 is installed on the embedded plate 3. A base fire-retardant board 5 is fixedly installed on the top surface and the rear end face of the window sill support 4. A window sill decorative board 6 is laid on the base fire-retardant board 5.

[0038] The building curtain wall 2 has horizontally arranged curtain wall transverse ribs 21. The inner end face of the curtain wall transverse ribs 21 is fitted with the outer end face of the corresponding window sill decorative panel 6 with a gap, and a foam rod 7 is installed between the two.

[0039] A flame-retardant mounting bracket 8 is installed between the horizontal rib 21 of the curtain wall and the embedded plate 3. There are two flame-retardant mounting brackets 8, and a receiving space 9 is provided between the two flame-retardant mounting brackets 8. Rock wool 10 is installed in the receiving space 9.

[0040] The embedded plate 3, installed on the building wall 1, provides a mounting component for the window sill support 4. This allows the window sill support 4 to be fixedly connected to the embedded plate 3 via welding or other mechanical connections. The building wall 1 provides vertical support for the window sill support 4 through the embedded plate 3. The window sill support 4 forms the skeleton of the window sill structure. The window sill decorative panel 6 is installed on the window sill support 4 for covering and decoration, and its weight is directly borne by the building wall 1 through the window sill support 4, without being applied to the building curtain wall 2, thus preventing deformation of the building curtain wall 2 under pressure. The outer end of the window sill decorative panel 6 extends to the inner side of the curtain wall's horizontal rib 21 and faces it directly. A foam rod 7 is installed in the gap between them to seal the gap, ensuring a seamless and complete interior space. Additionally, the L-shaped embedded plate 3 covers the top and outer end faces of the building wall 1, acting as a protective structure to protect the corners and improve the stability of the building wall 1.

[0041] Rock wool 10 is installed on a flame-retardant mounting bracket 8. One end of the flame-retardant mounting bracket 8 is suspended from the horizontal rib 21 of the curtain wall, and the other end is fixed to the embedded plate 3. This allows the building wall 1 and the curtain wall structure to jointly support it, thereby reducing the load on the curtain wall structure and preventing the building curtain wall 2 from deforming due to excessive pressure. The flame-retardant mounting bracket 8 between the horizontal rib 21 of the curtain wall and the embedded plate 3 is located on the outside of the building wall 1 below the window sill support 4, in a relatively large space. This allows for greater flexibility in the shape of the flame-retardant mounting bracket 8, enabling the formation of various sizes and shapes of accommodating spaces 9 to accommodate different specifications of rock wool 10, thus improving the flexibility of rock wool 10 installation.

[0042] The rock wool 10 on the lower side and the base fire-retardant board 5 installed on the window sill support 4 constitute two fireproof structures, improving fire resistance.

[0043] In the above illustrative embodiment, the fire-resistant window sill structure at the interlayer of the curtain wall is constructed by installing an embedded plate 3 on the building wall 1 to fix the window sill support 4, and then installing the window sill decorative panel 6 onto the window sill support 4 to form the window sill structure. The window sill decorative panel 6 is supported by the building wall 1 through the window sill support 4. The window sill decorative panel 6 and the window sill support 4 are not connected to the building curtain wall 2, which reduces the load on the building curtain wall 2, prevents the curtain wall structure from being deformed or damaged due to excessive load, improves structural stability and safety, and leaves a connection for the flame-retardant mounting bracket 8 on the curtain wall transverse rib 21 of the curtain wall structure. The space facilitates the installation of the flame-retardant mounting bracket 8; the flame-retardant mounting bracket 8 is fixed by the embedded plate 3 and the horizontal rib of the curtain wall 21, and rock wool 10 is installed in the space between the two flame-retardant mounting brackets 8, so that the rock wool 10 is supported by both the building wall 1 and the curtain wall structure, which makes it more stable. Moreover, the two flame-retardant mounting brackets 8 are located in a large space between the embedded plate 3 and the horizontal rib of the curtain wall 21, and their shapes have a large degree of freedom. Thus, the corresponding accommodating space 9 can be formed according to the shape of the rock wool 10, which improves the freedom of fireproof material selection and solves the problem that the curtain wall structure is prone to deformation and damage when bearing too much load in the interlayer fireproof construction of the curtain wall.

[0044] In some embodiments, the embedded plate 3 has a vertically arranged first plate 31 and a horizontally arranged second plate 32. The first plate 31 is attached to the outer end face of the building wall 1 and is fixedly connected to it by a first expansion bolt 101. The second plate 32 is attached to the top surface of the building wall 1 and is fixedly connected to it by a second expansion bolt 102.

[0045] The embedded plate 3 is fixedly connected by two expansion bolts, and the two connection points are located in two mutually perpendicular directions, which improves the firmness of the connection between the embedded plate 3 and the building wall 1.

[0046] In some embodiments, the window sill support 4 includes a vertically arranged support beam 41 and a horizontally arranged cantilever beam 42. The top end of the support beam 41 is fixedly connected to the inner end of the cantilever beam 42 to make the window sill support 4 L-shaped. The bottom end of the support beam 41 is fixedly connected to the corner bracket 33 fixedly welded to the rear of the top surface of the embedded plate 3.

[0047] The window sill support 4 adopts a cantilever structure, with its top spaced apart from the building wall 1. The top horizontal window sill decorative panel 6 is raised to be flush with the horizontal rib 21 of the curtain wall, extending to the horizontal rib 21 and directly opposite it, ensuring the integrity of the interior decorative surface. In addition, a large space is formed under the window sill support 4, which improves the convenience of installing the flame-retardant mounting bracket 8 and the rock wool 10.

[0048] In some embodiments, an inclined bracing beam 43 is fixedly installed between the bottom of the embedded plate 3 and the outer end of the cantilever beam 42, further enhancing the support capacity and structural stability of the cantilever beam 42. The inclined arrangement of the bracing beam 43 effectively disperses the load borne by the cantilever beam 42, reducing the possibility of structural deformation.

[0049] In some embodiments, the cantilever beam 42, the support beam 41, and the diagonal brace beam 43 are all made of galvanized steel pipes. Galvanized steel pipes are readily available and easy to weld or mechanically fix to the embedded plate 3, reducing the manufacturing cost and installation difficulty of the window sill support 4. Furthermore, galvanized steel pipes have strong durability and corrosion resistance, extending the service life of the window sill support 4.

[0050] In some embodiments, the two flame-retardant mounting brackets 8 are a first mounting bracket 8A and a first mounting bracket 8B, respectively.

[0051] The first mounting bracket 8A includes a first suspension plate 81, a support plate 82, and a first connecting plate 83. The first suspension plate 81 is vertically arranged, with its top end connected to the horizontal rib 21 of the curtain wall and its bottom end connected to the outer end of the support plate 82. The support plate 82 is horizontally arranged, with its rear end connected to the top end of the first connecting plate 83. The first connecting plate 83 is vertically arranged, attached to the outer surface of the embedded plate 3, and fixedly connected to it.

[0052] The first mounting bracket 8B includes a second suspension plate 84 and a second connecting plate 85. The second suspension plate 84 is vertically arranged, with its top end connected to the curtain wall horizontal rib 21 and its bottom end connected to the outer end of the second connecting plate 85. The second connecting plate 85 is horizontally arranged, with its rear end attached to and fixedly connected to the top surface of the embedded plate 3.

[0053] The accommodating space 9 is located between the support plate 82 and the second connecting plate 85.

[0054] Both flame-retardant mounting brackets 8 are formed by bending plates, thus creating a space 9 for installing rock wool 10. This design offers low manufacturing costs and high processing flexibility. The two flame-retardant mounting brackets 8 form a two-layer metal plate structure, positioned between the building curtain wall 2 and the building wall 1, acting as two barriers against flames and improving the structure's fire resistance.

[0055] In some embodiments, the first suspension plate 81 and the second suspension plate 84 are stacked sequentially from the inside out, and their top ends are fixedly connected to the horizontal rib 21 of the curtain wall by the same fixing bolt. The stacked arrangement allows the two flame-retardant mounting brackets 8 to support each other in the horizontal direction, improving their stability. The use of the same fixing bolt simplifies the installation process and improves construction efficiency.

[0056] In some embodiments, the bottom of the embedded plate 3 is fixedly connected to the outer end face of the building wall 1 by the first expansion bolt 101, and the first connecting plate 83 is fixedly connected to the bottom of the embedded plate 3 by the first expansion bolt 101.

[0057] The top of the embedded plate 3 is fixedly connected to the top surface of the building wall 1 by the second expansion bolt 102, and the second connecting plate 85 is fixedly connected to the top of the embedded plate 3 by the second expansion bolt 102.

[0058] The two flame-retardant mounting brackets 8 are connected to the embedded plate 3 by corresponding expansion bolts, which improves the stability of the bottom connection and fixation of the flame-retardant mounting brackets 8.

[0059] In some embodiments, rock wool 10 fills the accommodating space 9, with its rear end attached to the outer surface of the embedded plate 3, so that the rock wool 10 is as close as possible to the building wall 1, thereby increasing the fireproof coverage of the rock wool 10 and improving its fireproof performance.

[0060] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0061] The above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
