Description

Technical Field

[0001] The utility model relates to the field of composite boards, and in particular to a spliced ​​bidirectional composite board. Background Art

[0002] Two-way laminated slabs are a type of building material made of two or more layers of thin plates stacked perpendicular to each other. In the construction field, two-way laminated slabs are widely used as concrete formwork to support the load of concrete and keep the concrete flat and stable during construction.

[0003] However, when pouring concrete on the existing spliced ​​two-way composite slab, the contact area between the concrete and the two-way prefabricated composite slab is limited, and the two-way prefabricated composite slab cannot be fully locked with the later poured concrete.

[0004] Therefore, it is very necessary to invent a spliced ​​two-way composite plate. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a technical solution adopted by a spliced ​​two-way composite slab: a spliced ​​two-way composite slab, comprising a concrete precast slab, wherein: a plurality of vertical steel bars, transverse steel bars, truss steel bars and C-shaped channel steel plates are cast in the concrete precast slab, and the vertical steel bars, transverse steel bars and truss steel bars are fixedly connected, and the C-shaped channel steel plates and the truss steel bars are arranged alternately; both ends of the vertical steel bars are evenly exposed from both ends of the concrete precast slab; both ends of the transverse steel bars are evenly exposed from both sides of the concrete precast slab; the truss steel bars are exposed from the upper surface of the concrete precast slab; the opening of the C-shaped channel steel plate faces upward, and the opening of the C-shaped channel steel plate is flush with the upper surface of the concrete precast slab;

[0006] Preferably, a plurality of inner reinforcing ribs are evenly fixedly installed inside the opening of the C-shaped channel steel plate, and a plurality of lower reinforcing ribs are evenly fixedly installed on the bottom surface of the C-shaped channel steel plate, and a plurality of side reinforcing ribs and side reinforcing ribs 2 are evenly fixedly installed on both sides of the C-shaped channel steel plate; the lower reinforcing ribs, side reinforcing ribs and side reinforcing ribs 2 are all cast in the concrete precast slab.

[0007] Preferably, a plurality of grooves are evenly arranged on the upper surface of the precast concrete panel.

[0008] Preferably, a plurality of notches are evenly formed on the upper surfaces of the inner reinforcing rib, the side reinforcing rib and the second side reinforcing rib.

[0009] Preferably, a plurality of notches 2 are evenly formed on both sides of the lower reinforcing rib.

[0010] Preferably, the outer surfaces of the vertical steel bars, transverse steel bars, truss steel bars, C-shaped channel steel plates, inner reinforcement ribs, lower reinforcement ribs, side reinforcement ribs and side reinforcement ribs 2 are all provided with corresponding anti-corrosion coatings.

[0011] Compared with the prior art, the advantages of the utility model are:

[0012] The overall arrangement of the utility model can allow the post-poured concrete to enter the C-shaped channel steel plate when pouring concrete on the concrete precast plate. In this way, not only the contact area between the post-poured concrete and the concrete precast plate can be increased, but also the post-poured concrete and the concrete precast plate can be better locked together, thereby making the whole safer and more reliable.

[0021] Embodiment 1

[0022] Reference Figure 1-3 , a spliced ​​two-way composite slab, comprising a concrete precast slab 1, wherein: a plurality of vertical steel bars 2, transverse steel bars 3, truss steel bars 4 and C-shaped channel steel plates 5 are cast in the concrete precast slab 1, and the vertical steel bars 2, transverse steel bars 3 and truss steel bars 4 are fixedly connected, and the C-shaped channel steel plates 5 and the truss steel bars 4 are arranged alternately. Through the arrangement of the C-shaped channel steel plates 5, when the concrete is poured later, the post-cast concrete can enter the C-shaped channel steel plates 5, thereby increasing the contact area with the post-cast concrete, and allowing the concrete precast slab 1 to be integrated with the post-cast concrete; both ends of the vertical steel bars 2 are evenly exposed from both ends of the concrete precast slab 1; both ends of the transverse steel bars 3 are evenly exposed from both sides of the concrete precast slab 1; the truss steel bars 4 are exposed from the upper surface of the concrete precast slab 1; the opening of the C-shaped channel steel plate 5 faces upward, and the opening of the C-shaped channel steel plate 5 is flush with the upper surface of the concrete precast slab 1;

[0023] It should be noted that when the precast concrete panel 1 is poured, the vertical steel bars 2, the transverse steel bars 3 and the truss steel bars 4 are first poured into the concrete of the precast concrete panel 1, and then the C-shaped channel steel plate 5, the lower reinforcement 7, the side reinforcement 8 and the side reinforcement 9 are inserted into the poured concrete, and the opening of the C-shaped channel steel plate 5 is made flush with the upper surface of the precast concrete panel 1, so as to prevent the concrete of the precast concrete panel 1 from entering the opening of the C-shaped channel steel plate 5.

[0024] A plurality of inner reinforcing ribs 6 are evenly and fixedly installed inside the opening of the C-shaped channel steel plate 5. Through the arrangement of the inner reinforcing ribs 6, the C-shaped channel steel plate 5 can be better solidified with the post-cast concrete and the locking strength with the post-cast concrete can be improved. A plurality of lower reinforcing ribs 7 are evenly and fixedly installed on the bottom surface of the C-shaped channel steel plate 5. A plurality of side reinforcing ribs 8 and side reinforcing ribs 9 are evenly and fixedly installed on both sides of the C-shaped channel steel plate 5. The lower reinforcing ribs 7, the side reinforcing ribs 8 and the side reinforcing ribs 9 are all cast in the precast concrete slab 1 so as to improve the solidification between the C-shaped channel steel plate 5 and the precast concrete slab 1 and improve the strength and stability therebetween.

[0025] The upper surface of the precast concrete panel 1 is evenly provided with a plurality of grooves 10 so as to better solidify the precast concrete panel 1 and the later poured concrete together.

[0026] A plurality of notches 11 are evenly formed on the upper surfaces of the inner reinforcing ribs 6, the side reinforcing ribs 8 and the second side reinforcing ribs 9; a plurality of second notches 12 are evenly formed on both sides of the lower reinforcing ribs 7; by providing the notches 11 and the second notches 12, the contact area between the C-shaped channel steel plate 5 and the precast concrete panel 1 can be increased so that they can be better locked together.

[0027] The outer surfaces of the vertical steel bars 2, the transverse steel bars 3, the truss steel bars 4, the C-shaped channel steel plates 5, the inner reinforcement 6, the lower reinforcement 7, the side reinforcement 8 and the side reinforcement 9 are all provided with corresponding anti-corrosion coatings to improve the overall anti-corrosion ability. The anti-corrosion coating adopts existing technology, such as paint in the existing technology, but is not limited to this one, and other means of anti-corrosion treatment can also be performed; since anti-corrosion treatment is a very mature technology available and there are many types, it will not be described in detail here.

[0028] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
