Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of fabricated building, especially relates to a prestressed large-span dense rib hollow planting roof panel. BACKGROUND

[0002] With the development of modern industrial technology, the fabricated building gradually replaces the ordinary building system in the prior art with the advantages of fast construction speed, small restriction by weather conditions, saving labor force and the like, the roof panel used in the fabricated building is all factory production embedded connecting plate, the embedded connecting plate is connected through steel columns to form a building three-dimensional space, and the roof panel is laid on the building three-dimensional space. The roof as a maintenance structure of the building plays an important role in building energy saving. Generally, the roof panel is a concrete solid plate, which is heavy in quality, high in manufacturing cost and transportation cost, and its heat preservation effect needs to be improved. The current roof insulation layer is basically constructed and arranged after the construction of the roof structure layer, which delays the construction period and increases the cost of building energy saving.

[0003] For example, the patent number is 202420102855.4, and the patent name is a greening and heat preservation integrated composite dense rib sandwiched concrete roof panel. The whole roof panel is formed by sequentially splicing a plurality of roof panels. A plurality of longitudinal rib beams of each roof panel are arranged at a certain interval. The lower end of the longitudinal rib beam is provided with an extension beam. A light fiber concrete planting box and a transverse rib beam are arranged between every two adjacent longitudinal rib beams. A groove is formed in the upper end surface of each light fiber concrete planting box. A plurality of first connecting holes and a plurality of second connecting holes are respectively formed in the longitudinal rib beam corresponding to the groove position along the width direction and the length direction of the longitudinal rib beam. The groove is filled with a planting soil layer, and the planting soil layer is provided with a plant layer. A fastener is arranged in the first connecting hole and the second connecting hole corresponding to the position of every two adjacent roof panels. The greening and heat preservation integrated composite dense rib sandwiched concrete roof panel provided by the utility model can be provided with a plant layer in the planting soil layer, and realizes the greening and heat preservation integration.

[0004] Although the above patent solves the problems of construction period and building energy saving, the design of the inverted T-shaped longitudinal auxiliary beam makes it impossible to design a large span, and the roof assembly can only be realized by splicing multiple times. When the roof panel with the above technical solution has a large span, the bottom of the panel is prone to cracking during transportation and hoisting, which affects the subsequent normal use. UTILITY MODEL CONTENTS

[0005] Therefore, the utility model provides a prestressed large-span dense rib hollow planting roof panel.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] The utility model provides a prestressed large span dense rib hollow planting roof panel, including a plurality of rectangular distribution planting box, the planting box between the adjacent front and back both ends is provided with transverse beam, the planting box between the adjacent left and right both ends is provided with I -shaped longitudinal beam, the planting box between the outermost side is provided with U type longitudinal beam.

[0017] The I -shaped longitudinal beam and U type longitudinal beam are adopted, compared with the I -shaped longitudinal beam, the upper end of the planting box and transverse beam are also limited, so that the I -shaped longitudinal beam and U type longitudinal beam generate opposite force displacement opposite to the working load during transportation and use, are not easy to crack, and the large span roof panel design is realized.

[0018] Because of the design of the I -shaped longitudinal beam and U type longitudinal beam, compared with the I -shaped longitudinal beam, the planting soil layer can exceed the planting box more during the covering of the planting soil layer, so the planting area is larger, and the planting soil layers under the same column are connected, and the characteristics of the I -shaped longitudinal beam under the planting soil layer are also retained.

[0019] The prestressed steel bars arranged inside the I-shaped and U-shaped longitudinal beams further stabilize the stability of the large-span design of the technical scheme. BRIEF DESCRIPTION OF DRAWINGS

[0024] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0025] In the description of the utility model, unless otherwise specified, the meaning of "multiple" is two or more than two; the orientation or position relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail" and the like is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second", "third" and the like are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0026] In the description of the utility model, it should be noted that, unless otherwise specified and limited, the terms "connected", "connected" should be broadly understood, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium. For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0027] As Figures 1 to 3 shown, the main components of the technical scheme of the embodiment include: planting box 1, transverse beam 2, I-shaped longitudinal beam 3, U-shaped longitudinal beam 4.

[0028] As shown in the accompanying drawings Figure 1 It can be seen that the U-shaped longitudinal beams 4 are located at both ends of the entire roof panel and are parallel to each other, and the U-shaped grooves of the U-shaped longitudinal beams 4 are oppositely arranged;

[0029] A plurality of I-shaped longitudinal beams 3 are arranged in parallel between the two U-shaped longitudinal beams 4;

[0030] The left and right sides of the planting box 1 are arranged in the U-shaped grooves of the U-shaped longitudinal beams 4 and the recesses of the I-shaped longitudinal beams 3, forming a clamping form;

[0031] The transverse beams 2 are arranged on the front and rear sides of the planting box 1, and the left and right ends of the transverse beams 2 are also arranged in the U-shaped grooves of the U-shaped longitudinal beams 4 and the recesses of the I-shaped longitudinal beams 3.

[0032] The above description is the main part of the present application, and the U-shaped longitudinal beams 4 and the I-shaped longitudinal beams 3 are designed compared with the inverted T-shaped design, which limits the upper end of the planting box 1 and the transverse beam 2, so that the longitudinal beams of the I-shaped and U-shaped generate a counter-displacement of the counter-force opposite to the working load during hoisting and use, which is not easy to crack, thereby realizing the design of a large-span roof panel.

[0033] In order to ensure the further stability in the process of large span, a plurality of prestressed steel bars 6 are arranged in the lower end of the I-shaped longitudinal beam 3 and the U-shaped longitudinal beam 4.

[0034] In order to facilitate the connection of the roof panel with other panels or the roof panel, a plurality of first connecting holes 7 are arranged on the side surface of the U-shaped longitudinal beam 4, and a plurality of second connecting holes 8 are arranged on the outermost transverse beam 2, and both the first connecting holes 7 and the second connecting holes 8 penetrate into the recess of the planting box 1, which is convenient for subsequent use of a screw rod and a nut for fixing.

[0035] As shown in the accompanying drawings Figure 1 As shown in the left two columns of the accompanying drawings, the recess in the planting box 1 can adopt a waffle-shaped recess or a sun-shaped recess, and of course the middle partition strip in the sun-shaped recess can be parallel to the longitudinal beam or vertically placed, and considering the structural stability, it is best to vertically place.

[0036] After the above structure is processed in the factory, it can be hoisted to the roof to use the roof panel, and after hoisting is completed, the planting soil layer 5 is arranged;

[0037] As shown in the accompanying drawings Figure 1 to Figure 3As shown, for the arrangement of the planting soil layer 5, the user can flexibly change according to the needs, for example, the planted plants need to be arranged in a grid (such as succulents, flowers, etc.), and the planting soil layer 5 is flush with or lower than the upper end surface of the planting box 1, so that the soil between the grooves of the planting box 1 does not affect each other, increasing the aesthetic appearance, if the planted plants are not concerned about the aesthetic appearance and need a large area of planting area (such as vegetables), the planting soil layer 5 can be higher than the upper surface of the planting box 1 and lower than or equal to the upper surface of the I-shaped longitudinal surface, so that the planting soil layer 5 forms a long strip planting area, compared with the surface area of the soil arranged in a grid, the planting area is larger (because the soil covers the upper end surface of the internal baffle of the planting box 1), and the planting area is more.

[0038] Therefore, the technical solution retains the grid design of the inverted T-shaped longitudinal beam design on the planting soil layer 5, and also adds the overall soil covering design, thereby increasing the practical performance.

[0039] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent replacements or changes according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
