Description
Technical Field
The utility model relates to a concrete slab, especially the steel construction concrete slab who pours concrete formation on the steel sheet.
Background
The steel plate is a novel building structure by pouring concrete on the basis of the steel plate, can be used as a floor slab and a shear wall, and can take the advantages of both steel and concrete into consideration. The steel plate among the prior art is smooth, and the workman encloses the wooden pattern on the steel plate all around and forms the pouring chamber, toward pouring intracavity concreting, the steel sheet is glued to after the concrete sets, forms steel construction concrete slab jointly with the steel plate. The prior art has the defects that the adhesion between the concrete layer and the steel plate is not firm enough, and the steel plate is likely to fall off when being subjected to external force in the using process.

FIG. 2 is a schematic front view cross-sectional view of a steel plate;
fig. 3 is a schematic top view of a steel structural concrete panel (concrete layer not shown);
in the figure: 1. a steel plate; 2. a narrow-mouth groove; 3. a right connecting rod; 4. a rod cap; 5. a left connecting rod; 6. wood molding; 7. a concrete layer; 8. and (5) concrete blocks.
Detailed Description
The invention will be described in further detail with reference to the following detailed description.
As shown in fig. 1, the top wall of the steel plate 1 is provided with a left connecting rod 5 inclining towards the left side and a right connecting rod 3 inclining towards the right side, the right connecting rod 3 is arranged in front of the left connecting rod 5, anti-skid stripes (not shown in the figure) are distributed on the outer side walls of the connecting rods, the top end of each connecting rod is provided with a rod cap 4, the middle part of the top wall of the rod cap 4 is bulged, and the bottom wall is a plane wall. As shown in fig. 2, a narrow groove 2 is formed at the top of the steel plate 1, and the narrow groove 2 gradually narrows from the bottom to the top. The worker surrounds the periphery of the steel plate 1 by four wood moulds 6 to form a pouring cavity together with the steel plate 1, the worker pours concrete into the pouring cavity until the rod caps 4 of the connecting rods are submerged, a concrete layer 7 is formed on the top wall of the steel plate 1 after the concrete is solidified, and a concrete clamping block 8 is formed in the narrow groove 2, on one hand, the rod caps 4 are clamped in the concrete layer 7 to hang the steel plate 1 through the connecting rods to realize connection, and the anti-skid stripes on the connecting rods increase the friction force between the connecting rods and the concrete layer 7 to reduce the stress of the rod caps 4; on the other hand, the concrete block 8 which is clamped into the narrow groove 2 holds the inner side wall of the narrow groove 2 by the outer side wall thereof.
Preferably, as shown in fig. 3, these left and right connecting rods 5 and 3 are arranged side by side in the front-rear direction with the shafts of two connecting rods adjacent in the front-rear direction being staggered with each other (see fig. 1), and such connecting rods are provided with three rows of left, middle and right. The narrow-mouth grooves 2 are positioned between two adjacent rows of connecting rods and are arranged in parallel in a front-back transverse mode, namely, the two rows of narrow-mouth grooves 2 and the three rows of connecting rods are arranged in a left-right transverse mode at intervals, so that the concrete layer 7 is stressed evenly and is not easy to generate local fragmentation.
The above description is only the embodiments of the present invention, and the scope of protection is not limited thereto. The insubstantial changes or substitutions will now be made by those skilled in the art based on the teachings of the present invention, which are still within the scope of the claims.
