Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a high-performance concrete composite trestle board and a preparation method thereof. Background Art

[0002] The trestle board is a kind of board used to build a trestle. A trestle is a building shaped like a bridge, usually built on the water, between buildings or in terrain such as valleys, for the passage of people, transportation of goods or placement of equipment.

[0003] Trestle boards can be made of a variety of materials, the most common of which are wood, steel and concrete. Wood trestle boards have a certain elasticity and natural beauty, but their durability is relatively poor and they need to be treated for corrosion; steel trestle boards have high strength and good toughness, can withstand large loads, and are relatively easy to install; concrete trestle boards have good durability and stability, and high compressive strength.

[0004] Due to the high density of concrete itself, the concrete trestle board has a heavy weight, which will increase the construction cost and difficulty of installation, and its earthquake resistance is poor. Summary of the invention

[0005] The purpose of the present invention is to overcome the existing defects and provide a high-performance concrete composite trestle board and a preparation method thereof, which can reduce the weight while enhancing the earthquake resistance and saving the cost.

[0006] The technical solution to achieve the above-mentioned purpose is: a high-performance concrete composite trestle board, including multiple steel beams, each of which is parallel to each other, with the same spacing between each of the steel beams, a steel plate welded on the upper surface of each of the steel beams, the steel plate is perpendicular to the multiple connected steel beams, and multiple strip holes are evenly opened on the steel plate.

[0007] Preferably, a rib is welded between every two adjacent steel beams.

[0008] Preferably, the upper end of each rib passes through two corresponding strip holes and is welded to the steel plate.

[0009] Preferably, a steel mesh is installed on the upper surface of each of the steel plates, and concrete is poured on the upper surface of each of the steel plates, and the concrete covers the upper end of each rib and the steel mesh.

[0010] Preferably, the steel beams include but are not limited to H-shaped steels, channel steels and I-shaped steels.

[0011] A method for preparing a high-performance concrete composite trestle slab comprises the following steps: S1 places the steel beams in parallel and installs all the ribs between the steel beams; S2: Multiple strip holes are evenly opened on the steel plate, and then the steel plate is vertically laid on each steel beam, so that each strip hole of each steel plate is just fitted on the corresponding rib plate, and then the contact surfaces of the steel plate and each rib plate are welded together, and then the steel plate and each steel beam are welded together; S3 installs a steel mesh on the upper surface of the steel plate, and then pours concrete on the upper surface of the steel plate.

[0012] The beneficial effects of the present invention are as follows: a steel plate is welded on the upper surface of each steel beam, a rib is connected to every two adjacent steel beams, the upper end of each rib passes through the steel plate and is welded thereto, concrete is poured on each steel plate, replacing the traditional integral casting, which greatly reduces the amount of concrete used, thereby reducing the weight of the structure, and installing multiple ribs and steel plates can enhance the seismic resistance and strength of the structure, saving costs; Concrete covers the upper end of each rib and the steel mesh, and the steel mesh can prevent the subsequent covering concrete from cracking, thereby ensuring the durability of the structure.

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] like Figure 1-2 As shown, a high-performance concrete composite trestle slab comprises a plurality of steel beams 1, a steel plate 2 and a plurality of ribs 3.

[0018] Specifically, the steel beams 1 are parallel to each other, the spacing between the steel beams 1 is the same, a steel plate 2 is welded on the upper surface of each steel beam 1, the steel plate 2 is perpendicular to the multiple connected steel beams 1, and a plurality of strip holes are evenly opened on the steel plate 2; a rib 3 is welded between every two adjacent steel beams 1; the upper end of each rib 3 passes through two corresponding strip holes and is welded to the steel plate 2.

[0019] Specifically, a steel mesh is installed on the upper surface of each steel plate 2, and concrete 4 is poured on the upper surface of each steel plate 2, replacing the traditional integral casting molding, which greatly reduces the use of concrete, thereby reducing the weight of the structure. At the same time, installing multiple ribs 3 and steel plates 2 can enhance the seismic resistance and strength of the structure and save costs; concrete 4 covers the upper end of each rib 3 and the steel mesh, and the steel mesh can prevent the concrete 4 covered later from cracking, thereby ensuring the durability of the structure.
