Technical Field

The utility model relates to the field of roadbed boxes, in particular to a roadbed box combining concrete and steel plates.

Background

The roadbed box is of a plate-shaped structure, the existing roadbed box mostly adopts a steel plate structure, a framework body of the roadbed box is composed of a longitudinal main rib framework and a transverse framework, a patterned anti-skid steel plate is sealed on the surface of the framework body, and a flat steel plate is sealed on the reverse side of the framework body, so that a box body is integrally formed.

SUMMERY OF THE UTILITY MODEL

The utility model provides a concrete and steel plate combined roadbed box which is simple in structure, high in overall strength, low in cost and long in service life.

In order to achieve the purpose, the utility model provides the following technical scheme: a concrete and steel plate combined roadbed box, comprising:

the steel plate layer is positioned at the bottom of the roadbed box;

splicing the concrete layers, and uniformly arranging the concrete layers on the upper sides of the steel plate layers in parallel;

gaps are reserved between adjacent spliced concrete layers, and deformable material strips are filled in the gaps.

Preferably, the spliced concrete layer is made of UHPC materials.

Preferably, the deformable material strip is made of polyurethane concrete.

Preferably, the steel plate layer is of a hollow plate-shaped structure, and a plurality of reinforcing plates are arranged in the steel plate layer in a transverse and vertical mode.

Compared with the prior art, the utility model has the beneficial effects that:

the structure is simple, the steel plate layer and the concrete layer are combined together, the cost of the roadbed box is greatly reduced, the excellent performances of corrosion resistance, moisture resistance, rust resistance and the like of the roadbed box are improved, the bottom stress is more uniform, and the roadbed box is not easy to deform and damage.

Detailed Description

In the following, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the drawings in the embodiments of the present invention, and it should be noted that all directional indicators (such as up, down, left, right, front, and back) in the embodiments of the present invention are only used for explaining a relative position relationship between components, a motion situation, and the like in a certain specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is changed accordingly.

In addition, the descriptions related to "first", "second", etc. in the present invention are only for descriptive purposes and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless explicitly specifically defined otherwise.

In the present invention, unless otherwise expressly stated or limited, the terms "connected," "secured," and the like are to be construed broadly, and for example, "secured" may be a fixed connection, a removable connection, or an integral part; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In addition, the technical solutions in the embodiments of the present invention may be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination of technical solutions should not be considered to exist, and is not within the protection scope of the present invention.

As shown in fig. 1, the utility model relates to an embodiment, in particular to a concrete and steel plate combined roadbed box, which comprises a steel plate layer 1 positioned at the bottom of the roadbed box, wherein at least two spliced concrete layers 2 are arranged on the upper side of the steel plate layer 1 side by side;

gaps are reserved between the adjacent spliced concrete layers 2 and filled with strips 3 of deformable materials, and the spliced concrete layers 2 are made of UHPC materials.

Ultra-High Performance Concrete (UHPC) is called active Powder Concrete (RPC) for short, is the most innovative cement-based engineering material in the last thirty years, realizes the large span of the Performance of the engineering material, and has excellent wear resistance and explosion resistance. The cement-based material is an ultrahigh-strength cement-based material with high strength, high toughness and low porosity. It minimizes defects (voids and microcracks) within the material to achieve ultra-high strength and high durability.

Simultaneously, but the strip of deformable material 3 adopt the polyurethane concrete, use the deformability between the adjacent concatenation concrete layer 2 of polyurethane concrete greatly increased.

In this embodiment, the steel deck 1 is a hollow plate-shaped structure, and a plurality of reinforcing plates are vertically and horizontally arranged in the steel deck 1, so that the overall strength of the steel deck 1 is improved.
