Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and specifically relates to a hollow arch plate for building construction. Background Technology

[0002] In the field of construction engineering, especially in the construction of underground structures such as cable trenches and cable wells, traditional building panels present numerous problems in practical applications. Currently, most traditional building panels are made of cast-in-place or precast concrete slabs. From a mechanical performance perspective, to meet strength requirements, the thickness of the slabs often needs to be increased, directly resulting in excessive weight. Heavy equipment is required during transportation and hoisting, which not only increases construction costs but also leads to extremely low construction efficiency. Furthermore, concrete itself has poor environmental performance; its production process generates high carbon emissions, and the recycling rate of concrete after building demolition is less than 30%, resulting in significant resource waste and environmental pollution.

[0003] Currently, some building construction uses lightweight panels, such as GRC and ALC panels. While this reduces weight to some extent, most of these panels are flat structures. Such flat structures have low bending stiffness, which cannot meet the load-bearing requirements of actual engineering projects. Furthermore, these panels are typically designed as straight plates. When used in underground pre-embedded construction, the panels may be subjected to compressive forces from the underground soil. The straight plate structure is prone to stress concentration, making it susceptible to brittle fracture under impact loads, further limiting its application in practical engineering. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a hollow arch panel for building construction that meets the requirements of lightweight construction while also possessing high strength and good durability.

[0005] Therefore, the technical solution of this utility model is: a hollow arch panel for building construction, comprising a panel body, the panel body being integrally extruded from lightweight material; the panel body having an overall arched structure with arch toes on both sides; the panel body having a hollow structure with several webs inside, and the webs dividing the interior of the panel body into multiple continuous rectangular, triangular or trapezoidal hollow cavities.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the lightweight material is PVC or aluminum alloy.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the main body of the plate has a left-right symmetrical structure, and the two sides of the arch toe have a hollow rectangular structure.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the hollow structure of the main body of the plate has a rectangular hollow cavity in the middle and continuous and uniform triangular hollow cavities on both sides.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the arch structure has a rise of ≤200mm, a span of ≤1500mm, and a rise-to-span ratio of ≤0.13.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: the angle between the web and the tangent at the top of the arched structure is 45 degrees to 90 degrees.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme: the main body of the plate includes an inner plate, an outer plate, and a web between the two. The wall thickness of the inner plate, the outer plate, and the web is 1~5 mm, and the wall thickness of the outer plate is greater than that of the inner plate.

[0012] Based on the above scheme and as a preferred embodiment of the above scheme: the inner layer plate and the outer layer plate are concentric arc surface structures, and the arc surface shape is a circular arc, a parabola or a catenary.

[0013] Based on the above scheme and as a preferred embodiment of the above scheme: the bottom or side surface of the arch toe is provided with a groove, and a water-stopping strip is provided in the groove.

[0014] Based on the above scheme and as a preferred embodiment of the above scheme: one or more of the following can be placed in the hollow cavity: heat insulation layer, sound insulation layer, and pipeline.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The panels are made of lightweight materials such as PVC or aluminum alloy through integral extrusion molding. Compared with traditional concrete panels, the weight of the panels is significantly reduced, which solves the problem that the heavy weight of traditional panels leads to the need for heavy equipment for transportation and hoisting, as well as low construction efficiency, and reduces construction costs.

[0017] The overall structure of the plate is arched, and combined with the internal web, it forms a stable mechanical structure. The arched structure naturally has good compressive strength and can effectively distribute pressure; the web further enhances the strength of the plate. The inclined web and the vertical web work together to distribute stress, making the plate more stable under pressure, improving bending stiffness, and meeting the load-bearing requirements in actual engineering. This avoids the problem of flat plate structures failing to meet load-bearing requirements due to low bending stiffness.

[0018] The web divides the interior of the slab into multiple continuous rectangular, triangular, or trapezoidal hollow cavities, optimizing stress distribution. In particular, the specific angle between the inclined web and the tangent at the top of the arched structure, and the perpendicularity of the vertical web to the tangent at the top of the arched structure, allow the slab to more effectively disperse stress when subjected to external forces such as the compressive force of the underground soil. This avoids stress concentration, reduces the risk of brittle fracture under impact loads, improves the durability of the slab, and overcomes the defect of traditional straight slab structures being prone to brittle fracture due to stress concentration during underground pre-embedded construction.

[0019] By abandoning high-carbon-emission concrete materials and choosing lightweight materials, carbon emissions in the production process of building materials are reduced from the source, which is in line with the concept of environmental protection. Attached Figure Description

[0023] In the description of this utility model, it should be noted that the directional terms such as "center", "horizontal (X)", "longitudinal (Y)", "vertical (Z)", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this utility model.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" or "a number" means two or more, unless otherwise explicitly specified.

[0025] See the attached drawings. The hollow arch panel for building construction described in this embodiment includes a panel body 1, which is integrally extruded from a lightweight material. The lightweight material can be PVC or aluminum alloy, which are extrudable materials. The lightweight material reduces the weight of the panel, making it easier to install and transport later.

[0026] The main body 1 of the board is a symmetrical structure with an overall arched shape. The arch height is ≤200mm, the span is ≤1500mm, and the span-to-span ratio is ≤0.13. The arched structure naturally possesses excellent compressive strength and can effectively distribute pressure. The main body 1 has arch toes 2 on both sides. The arch toes 2 are hollow rectangular structures that overlap with the supports (walls, columns, or beams), facilitating rapid assembly during construction and improving construction efficiency. Additionally, if water-stopping is required at the installation location, a groove (not shown in the figure, but can be set according to actual needs) can be provided on the bottom or side of the arch toes 2, and a water-stopping strip can be installed within the groove. If water-stopping is not required, this is not necessary.

[0027] The main body 1 of the sheet material includes an inner layer 11 and an outer layer 12. The inner and outer layers are concentric arc surfaces, which can be circular, parabolic, or catenary. There is a hollow structure between the inner and outer layers 11 and 12, and a plurality of webs 13 are provided within the hollow structure. The wall thickness of the inner layer 11, outer layer 12, and webs 13 is 1-5 mm, and the wall thickness of the outer layer is greater than that of the inner layer.

[0028] The web 13 is divided into inclined webs 14 and vertical webs 15. The angle between the inclined web 14 and the tangent at the top of the arched structure is 45 to 60 degrees, and the vertical web 15 is perpendicular to the tangent at the top of the arched structure. Each web divides the interior of the main body 1 into multiple continuous rectangular, triangular, or trapezoidal hollow cavities 16. The webs can be configured as fully inclined webs, fully vertical webs, or a combination of inclined and vertical webs, depending on actual needs.

[0029] like Figure 2 As shown, the hollow structure of the main body of the plate has a rectangular hollow cavity in the middle and continuous and uniform triangular hollow cavities on both sides. It can also be adjusted to other shapes of hollow cavities according to mechanical distribution. Simultaneously, the hollow cavities can be filled with heat insulation and sound insulation materials, or used for laying pipelines, etc., to achieve structural and functional integration.

[0030] The hollow arched panel described in this embodiment can be used as a wall panel for underground facilities such as cable wells and cable trenches. The arched side faces the underground soil layer, utilizing its own structural characteristics to cope with the squeezing pressure of the underground soil layer and extend its service life.

[0031] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
