Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated pavement, and particularly to a metal prefabricated pavement slab and its connection structure. Background Art

[0002] With the increasingly obvious development trend of building assembly and industrialization, as an important innovation in the construction industry, prefabricated pavement technology is gradually showing its unique advantages. Compared with traditional cast-in-place concrete pavements, prefabricated pavements, especially metal prefabricated pavements, have become the focus of the industry due to their short construction period, controllable quality, convenient maintenance and renewal, and strong recyclability.

[0003] In the existing prefabricated pavement technical solutions, concrete pavements dominate, but due to their unique properties, metal prefabricated pavements have been initially applied in specific scenarios such as construction temporary roads and airport standby emergency pavements. These metal prefabricated pavement solutions, such as direct laying of steel plates, welding of steel plates, and bolt connection of special steel plates, although meeting the requirements of rapid construction and load-bearing to a certain extent, still need to be optimized in terms of the connection structure of the pavement slabs, load transfer efficiency, installation convenience, and subsequent maintenance.

[0004] Especially in the paving plate solutions for airport standby emergency pavements, there are extremely high requirements for the flatness, load-bearing capacity, and installation speed of the pavement. Existing solutions such as rollable steel paving plates and snap-type steel paving plates, although meeting these requirements to a certain extent, still have room for improvement in terms of the stability of the inter-board connection structure, uniformity of load transfer, and convenience of disassembly and maintenance.

[0005] Therefore, there is an urgent need to develop a new type of metal prefabricated pavement slab and its connection structure to solve the problems existing in the prior art. Summary of the Invention

[0006] To solve the above problems, the present invention provides a metal prefabricated pavement slab and its connection structure, which can effectively transfer the coupling loads such as power and temperature in various directions between the plates; can realize the rapid assembly of the pavement, has a simple structural form, excellent load transfer capacity between the plates, a safe and reliable principle, and is convenient for disassembly, maintenance, and secondary utilization.

[0007] The technical solution of the present invention is as follows:

[0012] The edges of the metal plate intersecting with the outer rib are rounded.

[0013] Several of the radial ribs are arranged at equal angles with respect to the center of the metal plate.

[0014] Several of the anti-slip strips are radially arranged at equal angles with respect to the center of the metal plate.

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings through specific embodiments. Similar elements in different embodiments are denoted by related similar element numbers. In the following embodiments, many detailed descriptions are provided to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, or methods.

For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0032] In addition, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can also be reordered or adjusted in a manner obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for clearly describing a certain embodiment, and do not mean that they are the necessary sequences, unless it is stated that a certain sequence must be followed.

[0033] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the objects described, and do not have any sequential or technical meaning. And the "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connection (coupling).

[0034] As Figures 1 to 3 shown, the metal prefabricated assembled paving panel is composed of a metal plate 1, stiffening ribs 2, and anti-slip strips 3.

[0035] Among them, the metal plate 1 has a symmetric configuration with an even number of sides such as a quadrilateral or a hexagon, that is, the metal plate 1 is a regular polygon with an even number of sides, and the thickness of the metal plate 1 can be adjusted according to the use scenario and requirements.

[0036] The stiffening ribs 2 arranged under the metal plate 1 are divided into circular ribs 2-1, radial ribs 2-2, and outer ribs 2-3. The size and spacing of the ribs can be adjusted according to the use scenario and requirements; the stiffening ribs 2 not only strengthen the mechanical properties of the metal plate, but also play roles such as strengthening the mechanical transmission between the paving surface and the base layer, restricting the lateral displacement of the paving surface, and preventing the free edges of the edge paving panels from warping by being embedded in the base layer under the paving surface; the outermost one of the circular ribs 2-1 is located at the edge of the metal plate 1, and it is preferably integrally formed or firmly welded with the metal plate 1, and appropriate chamfers are made at the upper edges of the metal plate 1.

[0037] The anti-slip strips 3 arranged on the upper part of the metal plate 1 should be arranged radially. The height of the anti-slip strips should be 4-8 mm, and the shape of the anti-slip strips should be a combined shape of an arc-shaped edge and a top platform.

[0038] As Figures 4 to 6 shown, the periphery of the metal plate 1 is provided with male and female snap fasteners 4. The female snap opening 4-1 is a fixed card hole integrated with the metal plate 1, and the male snap fastener 4-2 is a snap fastener that can rotate around a fixed axis on the metal plate 1 in the vertical plane. The female snap opening of the adjacent metal plate 1 corresponds to the connection of the male snap fastener. The male snap fastener rotates and snaps into the female snap opening 4-1 of the adjacent metal plate 1. After multiple metal plates 1 are connected and pressed on the ground, the metal plates 1 are mutually overlapped and locked through the male and female snap fasteners 4, and a stable large-scale pavement can be formed without additional mechanical connection.

[0039] Installation steps of the metal assembled paving panel and its connection structure:

[0040] 1. Level the roadbed or lay the underlying layer of the pavement; 2. Position before laying the paving panel; 3. Lay the first paving panel; 4. According to the angle of the first paving panel, lay the adjacent paving panels according to the principle of corresponding male and female snap fasteners. During the laying process, the female snap opening of the later-laid plate presses on the male snap fastener of the previously laid paving panel, and the male snap fastener can be rotated and adjusted; 5. Apply force to press the paving panel to make the paving panel fit with the underlying layer, and the rib strips are embedded in the underlying layer.

[0041] Local replacement steps of the metal assembled paving panel and its connection structure:

[0042] 1. Use a sharp tool to dig out a hole under the snap fastener from the flat pore of the male and female snap fastener to form an operation space; 2. Rotate the male snap fastener to disengage from the female snap opening; 3. Pry up the paving block to be replaced and repaired and perform the required repair operations, such as re-laying the underlying layer; 4. Reinstall the paving block and re-fix the snap fastener; 5. Fill the hole at the rotation position of the snap fastener.

[0043] The technical problem to be solved by the present invention is to develop a metal assembled paving panel and its inter-panel connection structure that can bear vehicle loads and can be used as a pavement for use scenarios such as roads and airfields, is stable in work, simple in structure, and easy to install.

[0044] In the present invention, a metal plate with reinforcing ribs is used as the bearing pavement surface, and the bearing capacity of the plate is extremely strong. Anti-slip strips are provided on the upper surface of the plate to provide sufficient friction coefficient for the pavement surface. The plate surface has a symmetrical configuration, and male and female snaps are alternately arranged, so that the plates are universal plates without the need to select the configuration, and the procurement and installation are more convenient and practical. The connection between the plates is realized through male and female snaps. This snap structure can not only transfer the horizontal load between the plates, but also transfer the vertical load between the plates. The snap can form self-locking through the mutual pressing of male and female parts without additional mechanical connection. At the same time, by adjusting the size of the snap, the installation accuracy redundancy can be increased, making the installation more simple and rapid. The principle of this invention is safe and reliable, the structure is stable and firm, the installation method is simple and easy, and it is very convenient for subsequent maintenance and the recycling and reuse of the pavement plates.

[0045] The above uses specific examples to elaborate on the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the technical field to which the present invention pertains, according to the idea of the present invention, several simple deductions, deformations or substitutions can also be made.
