[0025] Please refer to Figures 1 to 4 , the present utility model provides a UHPC hollow flower window, including a flower window body, and the flower window body is precast with UHPC concrete;

[0026] The flower window body includes a window frame 1 and a hollow decorative panel 2. The hollow decorative panel 2 is arranged inside the window frame 1, and the window frame 1 and the hollow decorative panel 2 are set as an integrally formed structure;

[0027] The window frame 1 is of a rectangular structure; the hollow decorative panel 2 includes a decorative disc 21 and four decorative flower strips 22 arranged on the periphery of the decorative disc 21. The decorative disc 21 is connected to the window frame 1 through the decorative flower strips 22, and adjacent decorative flower strips 22 are connected to each other.

[0028] In an embodiment of the present utility model, the window frame 1 is of a rectangular frame structure, and a hollow decorative panel 2 is arranged inside. The hollow decorative panel 2 is composed of a decorative disc 21 and four decorative flower strips 22. The decorative disc 21 is located at the central position, and the four decorative flower strips 22 are located at the four corners inside the window frame 1. Adjacent decorative flower strips 22 are symmetrically arranged with each other, and adjacent decorative flower strips 22 are butt-jointed with each other.

[0029] Through the above structural design, the decorative flower strip 22 adopts a curved and extended arc structure. The shapes of flowers, flower stems and petals are outlined by multiple arc lines, and these arc lines respectively contact the window frame 1, adjacent decorative flower strips 22 and the decorative disc 21 at the central position to form a connected structure, providing support for the decorative disc 21 so that the decorative disc 21 can be stably arranged at the central position.

[0030] In this embodiment, the window frame 1 and the hollow decorative panel 2 are made by an integral molding method and are made of UHPC concrete. UHPC (Ultra High Performance Concrete) is a new type of building material, mainly composed of cement, quartz powder, wollastonite, fibers, etc. Compared with traditional concrete materials, UHPC concrete materials have higher strength, better durability and lighter weight, and are widely used in construction projects. The compressive strength of UHPC concrete can reach more than 150 MPa, far higher than that of traditional concrete materials. This high strength makes the hollow flower window made of UHPC concrete perform better in load-bearing and support. Compared with conventional concrete materials, UHPC concrete is light in weight and small in volume density. The hollow flower window made of UHPC concrete is not only convenient for handling and installation, but also can reduce the self-weight load of the building structure and has lower requirements for the installation environment. UHPC concrete has good acid and alkali resistance and weather resistance, and its penetration of chloride ions is also very weak. Therefore, the hollow flower window made of UHPC concrete performs more excellently in terms of service life. UHPC concrete has a high fiber content, is not easy to catch fire, and even if it catches fire, it will not burst, nor will it peel off like ordinary concrete, and has a particularly good fire prevention effect. In addition, UHPC concrete has strong structural stability, is not easy to crack and deform, and has a relatively long service life. Therefore, the hollow flower window made of UHPC concrete has more advantages in terms of safety and reliability.

[0031] In this embodiment, by optimizing the design of the structure of the flower window, it is made more aesthetically pleasing and at the same time has a good support effect, making the connection between the decorative plate 21 and the decorative flower strip 22 more stable and having better mechanical properties. In order to improve the structural strength of the flower window, this embodiment uses UHPC concrete as the main material for prefabrication, reducing the time of on-site casting construction and being superior in terms of lightweight and durability.

[0032] Preferably, the decorative plate 21 includes a central ring 211, a middle ring 212 and an outer ring 213. The central ring 211 and the outer ring 213 are butted through a plurality of arc-shaped connectors 214; the arc-shaped connectors 214 are composed of a pair of symmetrically arranged arc-shaped strips; the middle ring 212 is arranged between the central ring 211 and the outer ring 213 and is connected to the arc-shaped strips.

[0033] In this embodiment, the decorative plate 21 adopts a three-ring design, namely a central ring 211, a middle ring 212 and an outer ring 213. The central ring 211 is located at the center of the entire flower window. The middle ring 212 and the outer ring 213 are arranged in sequence. The three rings are connected and fixed by an arc-shaped connecting member 214. The arc-shaped connecting member 214 adopts a symmetrical structure and is composed of two arc-shaped bars. The arc-shaped bars intersect with the middle ring 212, and one end is connected to the outer side of the central ring 211, and the other end is connected to the inner side of the outer ring 213.

[0034] Further, in order to improve the strength of the arc-shaped connecting member 214, a short arc bar is also arranged between the two arc-shaped bars. The short arc bar is located between the middle ring 212 and the outer ring 213. The two ends of the short arc bar are respectively connected to the two arc-shaped bars, and multiple short arc bars outline a circular structure, improving the decorative effect of the decorative plate 21.

[0035] Preferably, the decorative flower strip 22 includes a flower strip main body 221. The flower strip main body 221 is provided with a plurality of curved and extended connecting nodes 222. The connecting nodes 222 are connected to the outer side wall of the outer ring 213. In this embodiment, the decorative flower strip 22 is provided with a plurality of connecting nodes 222, and the outer side wall of the outer ring 213 is connected through these nodes to provide support for the entire decorative plate 21.

[0036] Preferably, the flower window body is composed of a UHPC concrete layer and a fiber material layer. The fiber material layer is arranged inside the concrete layer. In this embodiment, the flower window body internally includes a UHPC concrete layer and a fiber material layer. UHPC concrete is used as the main material, and fiber materials are mixed therein. The comprehensive mechanical properties of UHPC concrete are improved through the fiber materials, enabling the hollow decorative plate 2 to achieve various complex hollow patterns without worrying about the connection parts being too slender and resulting in breakage or collapse.

[0037] Preferably, the UHPC concrete layer includes a first UHPC layer 3, a second UHPC layer 4 and a third UHPC layer 5; the fiber material layer includes a first fiber layer 6 and a second fiber layer 7. The first UHPC layer 3, the first fiber layer 6, the second UHPC layer 4, the second fiber layer 7 and the third UHPC layer 5 are arranged in sequence. In this embodiment, the flower window body adopts a multi-layer stacked structure, and two fiber layers are respectively arranged in the three UHPC layers, making the distribution of the fibers more uniform, thereby effectively improving the structural strength of the flower window body and enabling the flower window body to maintain the complex pattern effect more durably.

[0038] Preferably, the first fiber layer 6 includes a plurality of transverse fibers which are arranged horizontally; the second fiber layer 7 includes a plurality of longitudinal fibers which are arranged horizontally; the transverse fibers and the longitudinal fibers are arranged perpendicular to each other. In this embodiment, the two fiber layers adopt a transverse and longitudinal layout perpendicular to each other, which can effectively improve and enhance the performance of the UHPC concrete layer.

[0040] Preferably, the fiber material layer includes a plurality of fiber strips, the diameter of the fiber strips is 2 to 4 mm, and the length includes but is not limited to 10 mm, 20 mm, 25 mm, 30 mm, and 50 mm.

[0041] Preferably, the fiber strips are copolymerized formaldehyde fiber strips or ceramic fiber strips. In this embodiment, the fiber strips can be copolymerized formaldehyde fiber strips or ceramic fiber strips. The addition of the fiber strips provides higher matrix toughness for the UHPC concrete, prevents the expansion of local microcracks generated by uneven shrinkage during the setting process of the UHPC concrete, effectively prevents the occurrence of early cracking of the UHPC concrete, and prevents water from carrying chloride ions from seeping in through the surface gaps, greatly extending the service life of the UHPC concrete.

[0042] Preferably, on both sides of the back surface of the window frame 1, there are respectively provided buckles for hanging, and the two buckles are arranged parallel to each other. In some hot areas, if wet connection is used for the installation of the lattice window, the water evaporates quickly, which is not conducive to the connection of materials. Therefore, in this embodiment, buckles are provided, and the hollow-out lattice window can be directly hung on the wall, greatly improving the construction speed and at the same time ensuring the connection stability.

[0043] Compared with the prior art, the beneficial effects of the present utility model are as follows: The present utility model is reasonably designed and has a simple structure. By providing a hollow-out decorative panel in the window frame, the hollow-out decorative panel is composed of a decorative disc and four decorative flower strips, and the decorative flower strips have a symmetrical structure, which can provide good support for the decorative disc, not only being beautiful but also having a good ventilation effect. In order to improve the structural strength of the window frame and the hollow-out decorative panel, the present utility model uses UHPC concrete as the production material, and a fiber material layer is provided in the UHPC concrete layer. The fiber material layer can effectively improve the comprehensive mechanical properties of the UHPC concrete, making the flower window body made of UHPC concrete have higher strength, better durability, and lighter weight, and being able to reduce the later maintenance cost of the flower window.
