Description

Technical Field

[0001] The utility model relates to the technical field of casement doors and windows, and in particular to a bridge arch moment bearing structure system. Background Art

[0002] With the determination of the goal of building a resource-saving society, the country has higher and higher requirements for building energy conservation. Doors and windows, as the main structural components of the construction industry, must also adapt to the needs of the times. The industry generally conducts testing and evaluation on the three physical properties of doors and windows: air tightness, water tightness and wind pressure resistance.

[0003] In the prior art, a plurality of rectangular cavities are often provided at the bottom end of the lower profile of the casement door and window, and the plurality of rectangular cavities are directly installed on the installation interface (such as a window sill or a wall). The setting of the rectangular cavity can withstand a certain vertical force, but for lateral force, such as when subjected to impact by wind pressure, the rectangular cavity is difficult to provide effective lateral force support, resulting in the profile being twisted and stressed all around, which is very likely to cause the rectangular cavity and other parts of the profile to deform, seriously affecting the load-bearing effect of the profile; further, the deformation of the profile may also cause the connection between the frame materials to loosen, thereby causing safety hazards, and will also cause the sealing of the connection between the profiles and the connection between the profiles and the glass to fail, thereby reducing the sound insulation, heat insulation and other performances. Utility Model Content

[0004] The purpose of the utility model is to provide a bridge arch moment bearing structure system to at least improve the lateral and longitudinal force performance of the lower profile, thereby improving the deformation resistance of doors and windows, the connection sealing between profiles, and the connection sealing between profiles and glass, ensuring that the sound insulation and heat insulation performance of the profiles can be continuously and stably exerted.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] A bridge arch moment bearing structure system comprises a first cavity, a second cavity and a heat insulation strip for connecting the first cavity and the second cavity; the vertical cross section of the bottom wall of the first cavity is an arch structure; the vertical cross section of the bottom wall of the second cavity is a semi-arch structure.

[0007] Preferably, the bottom wall of the first cavity includes two first support plates and a first connecting plate disposed on top of the two first support plates; the vertical cross-sections of the two first support plates are in an "eight"-shaped structure.

[0008] Preferably, the bottom wall of the second cavity comprises a second connecting plate, and a second supporting plate arranged on a side of the second connecting plate away from the thermal insulation strip; the second supporting plate is arranged to be inclined downward in a direction away from the thermal insulation strip.

[0009] Preferably, the first connecting plate and the second connecting plate are planar structures or curved structures.

[0010] Preferably, a plurality of sub-cavities are provided in the first cavity and the second cavity.

[0011] Preferably, a trough is provided on the top of the load-bearing structure, and the vertical projection of the doors and windows arranged in the trough is just located within the vertical projection of the second support plate and the first support plate close to the second support plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] By setting the bottom of the first cavity (close to the indoor side) to an arch structure, and setting the bottom of the second cavity (close to the outdoor side) to a semi-arch structure, when subjected to lateral forces such as wind or other external forces, the synergistic effect of the arch and semi-arch structures can make the lateral force more uniform, thereby effectively improving the lateral force-bearing capacity of the profile; when subjected to longitudinal forces, the synergistic effect of the arch and semi-arch structures can distribute the forces to the entire structural system, thereby further improving the longitudinal force-bearing capacity and load-bearing capacity of the profile.

[0014] In addition, in addition to the longitudinal and lateral pressures, after the external pressures in other directions are applied to the cavity, due to the setting of the arch structure and the semi-arch structure (which is essentially also an arch structure), the external pressure can also be distributed to the entire structural system and transferred to the installation interface, effectively improving the force-bearing capacity of the load-bearing structure system.

[0015] Through the synergistic effect of the above-mentioned arch and semi-arch structures, the profile's ability to bear force in all directions can be effectively improved, thereby effectively improving the profile's load-bearing capacity and deformation resistance, effectively ensuring the sealing of the connection between profiles, the sealing of the connection between profiles and glass, and the stable performance of the profile's sound insulation and heat insulation properties, while enhancing the profile's service life.

[0019] Below in conjunction with the attached Figure 1 to Figure 2, the technical solutions in the embodiments of the utility model are clearly and completely described, but the protection scope of the utility model is not limited to the following.

[0020] Example 1

[0021] In the prior art, such as Figure 1 As shown, the lower profile of the casement door and window is often provided with a plurality of rectangular cavities, and the plurality of rectangular cavities are directly mounted on the mounting interface 300 (such as a windowsill or a wall). The rectangular cavity arrangement can have a certain bearing capacity in the vertical direction, but for lateral forces, such as when subjected to impacts such as wind pressure, the rectangular cavity is difficult to provide effective lateral force support, resulting in distortion of the profile on all sides, and further deformation of the rectangular cavity and other parts of the profile, seriously affecting the load-bearing capacity of the profile; further, the deformation of the profile may also cause the connection between the frame materials to loosen, thereby causing safety hazards, and will also cause the sealing of the connection between the profiles and the connection between the profiles and the glass to fail, thereby reducing the sound insulation, heat insulation and other performances.

[0022] Based on this, the utility model provides a bridge arch moment bearing structure system, that is, a profile below a door and window, such as Figure 2 As shown, it includes a first cavity 100, a second cavity 110 and a heat insulation strip 120 for connecting the first cavity 100 and the second cavity 110; the vertical cross-section of the bottom wall of the first cavity 100 is an arch structure; the vertical cross-section of the bottom wall of the second cavity 110 is a semi-arch structure, as shown in FIG. Figure 2 As shown, the semi-arched structure is provided with two first support plates 130, while the semi-arched structure is provided with only one second support plate 160, which is also essentially an arched structure. Figure 2 As shown, the bottom wall of the first cavity 100 includes two first support plates 130 and a first connecting plate 140 disposed on the top of the two first support plates 130; the vertical section of the two first support plates 130 is an "eight"-shaped structure. Further, the bottom wall of the second cavity 110 includes a second connecting plate 150 and a second support plate 160 disposed on the side of the second connecting plate 150 away from the thermal insulation strip 120; the second support plate 160 is disposed downwardly and tilted away from the thermal insulation strip 120.

[0023] Working principle: The arch structure is also called a thrust structure. Its characteristic is that it decomposes the pressure into downward pressure and outward thrust. It is the only structure that generates outward thrust among all structures. In the arch structure, because of the effect of horizontal thrust, the building can maintain structural stability continuously. The utility model sets the bottom end of the first cavity 100 and the second cavity 110 as an arch structure, which can distribute the external force to the entire structural system when subjected to horizontal left external force and vertical downward force and external force in other directions, and transfer it to the installation interface, effectively improving the load-bearing capacity and force-bearing capacity of the load-bearing structure system. Compared with the setting of the rectangular cavity in the prior art, the arch structure of the utility model can effectively improve the deformation resistance of the first cavity 100 and the second cavity 110 (i.e., the profile), thereby effectively ensuring the connection sealing between the profiles, the connection sealing between the profiles and the glass, and the stability of the sound insulation and heat insulation performance of the profiles, while enhancing the service life of the profiles.

[0024] Further, based on Example 1, the first connecting plate 140 and the second connecting plate 150 are planar structures (such as Figure 2 In this solution, whether the first connecting plate 140 and the second connecting plate 150 are a flat structure or an arch-like curved structure, the purpose of the utility model can be achieved.

[0025] Further, on the basis of Example 1, Figure 2 As shown, a plurality of sub-cavities are provided in the first cavity 100 and the second cavity 110. In actual implementation, appropriately increasing the number of sub-cavities can improve the load-bearing capacity and force-bearing capacity of the profile.

[0026] Further, on the basis of Example 1, a trough body (existing technology) is provided on the top of the load-bearing structure, such as Figure 2 As shown, the vertical projection of the door and window 200 arranged in the groove body is just located within the vertical projection of the second support plate 160 and the first support plate 130 close to the second support plate 160. In this solution, although the vertical projection of the door and window 200 is limited, it is actually to limit the position of the groove body by limiting the position of the door and window 200. In the prior art, due to the size setting problem of the rectangular cavity, after the door and window 200 is installed in the groove body, the right side of the door and window 200 can bear the weight through the rectangular cavity, but the left side is directly in a suspended state, such as Figure 1 As shown, the door and window 200 is subjected to uneven force, which seriously affects the stability of its operation. Figure 2 As shown, when the door and window 200 is placed in the trough, the second support plate 160 and the first support plate 130 on the right side respectively bear the weight evenly on both sides, thereby improving the force uniformity of the door and window 200 and improving the running stability of the door and window 200.
