Description

Technical Field

[0001] The utility model relates to the technical field of precast slabs, and more specifically, to a prefabricated and assembled concrete slab applicable to an oil drilling platform. Background Art

[0002] Concrete precast members formed by production and processing in a prefabrication yard are directly transported to a construction site for installation, so they are called precast slabs. Precast slabs are usually of a steel bar-concrete structure and are usually used for rapid construction or some places where on-site construction is not convenient. Among them, precast slabs are usually used as flat supporting slabs, and they are mainly used to bear pressure.

[0003] However, for an oil drilling platform, it is usually located at sea, and some drilling platforms are semi-floating on the sea surface. Although most of the drilling platforms are steel skeletons except for the pier structures, in some large-area platforms, reinforced concrete is still used as support, and precast concrete slabs are mostly used in the construction of drilling platforms. Compared with the concrete slabs used in in-situ pouring, the drilling platforms in long-term shaking need to consider their tensile properties more, that is, the strength of the connection between concrete slabs. Therefore, more applicable concrete slabs need to be designed for oil drilling platforms. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a prefabricated and assembled concrete slab applicable to an oil drilling platform, which has better connection strength and can have better tensile properties.

[0005] The embodiment of the utility model is realized by the following technical solutions: The prefabricated and assembled concrete slab applicable to an oil drilling platform of the utility model includes a slab body, a steel bar mesh arranged in the slab body, an L-shaped connecting rod connected to the steel bar mesh, and through holes opened on the slab body; the connecting rod on one slab body is inserted into the through holes of the adjacent slab body.

[0006] Further, a plurality of connecting rods are provided, and a plurality of through holes are provided; the connecting rods and the through holes correspond one by one.

[0007] Further, a first groove is provided on the lower side of the slab body, and the first groove is communicated with the through holes; the first groove is used to accommodate the connecting rods.

[0008] Further, a second groove is opened on the upper side of the slab body, and the second groove is used to communicate a plurality of through holes; a reinforcing rod is provided in the second groove, and the reinforcing rod is used to connect a plurality of connecting rods.

[0009] Further, a sleeve is provided in the through hole, and the sleeve is fixedly connected to the steel bar mesh.

[0010] Further, the steel mesh is provided with two layers, and the two layers of the steel mesh are connected by a plurality of connecting bars; the connecting rod is connected to the steel mesh located in the lower layer.

[0011] The technical solution of the embodiment of the present invention has at least the following advantages and beneficial effects: The prefabricated and assembled concrete slab applicable to an oil drilling platform of the present invention, during assembly, only needs to lay the slab bodies in sequence in the horizontal direction. When laying the slab bodies, insert the connecting rod on the previous slab body into the through hole on the subsequent connecting slab. After the overall laying is completed, perform concrete pouring to fill the gaps and the through holes on the slab bodies. In this way, adjacent slab bodies are connected by the connecting rods, having better tensile strength. When multiple layers need to be laid, longer connecting rods can be preset, and then the connecting rods of the lower layer slab bodies can penetrate into the through holes of the upper layer slab bodies to achieve a closer connection between layers and improve the overall tensile strength.

Specifically, the main body of the slab body 1 is made of concrete. During assembly, it is only necessary to lay the slab bodies 1 in sequence in the horizontal direction. When laying the slab body 1, insert the connecting rod 3 on the previous slab body 1 into the through hole 4 on the subsequent connecting slab. After the overall laying is completed, perform concrete pouring to fill the gaps and the through holes 4 on the slab body 1. In this way, the adjacent slab bodies 1 are connected by the connecting rod 3, having better tensile strength. When multi-layer laying is required, longer connecting rods 3 can be preset, and then the connecting rods 3 of the lower-layer slab body 1 can pass through the through holes 4 of the upper-layer slab body 1 to achieve a more compact connection between layers (as shown in the attached Figure 6 figure), with the orientation of the upper-layer slab body 1 being opposite to that of the lower-layer slab body 1), improving the overall tensile strength.

[0027] In this embodiment, a plurality of the connecting rods 3 are provided, and a plurality of the through holes 4 are provided; the connecting rods 3 and the through holes 4 are in one-to-one correspondence. Specifically, a plurality of connecting rods 3 can better improve the connection strength, and the connecting rod 3 and the steel mesh 2 are connected by welding.

[0028] In this embodiment, a first groove 5 is provided on the lower side of the slab body 1, and the first groove 5 communicates with the through hole 4; the first groove 5 is used to accommodate the connecting rod 3. Specifically, in this way, the connecting rod 3 can be completely embedded in the slab body 1 without protruding.

[0029] In this embodiment, a second groove 6 is opened on the upper side of the slab body 1, and the second groove 6 is used to communicate a plurality of the through holes 4; a reinforcing rod 8 is provided in the second groove 6, and the reinforcing rod 8 is used to connect a plurality of the connecting rods 3. Specifically, after the connecting rod 3 passes through the second groove 6, the plurality of connecting rods 3 are connected by the reinforcing rod 8, which can achieve a more stable connection. The connecting rod 3 and the reinforcing rod 8 are connected by welding.

[0030] In this embodiment, a sleeve 7 is provided in the through hole 4, and the sleeve 7 is fixedly connected to the steel mesh 2. Specifically, using the sleeve 7 is not only more convenient for positioning the through hole 4, but also the sleeve 7 can be directly used as a formwork for pouring when manufacturing the slab body 1.

[0031] In this embodiment, the steel mesh 2 is provided with two layers, and the two layers of the steel mesh 2 are connected by a plurality of connecting bars; the connecting rod 3 is connected to the lower-layer steel mesh 2.

[0032] In summary, for the prefabricated and assembled concrete slab applicable to an oil drilling platform in this embodiment, during assembly, it is only necessary to sequentially lay the slab body 1 horizontally. When laying the slab body 1, insert the connecting rod 3 on the previous slab body 1 into the through hole 4 on the subsequent connecting slab. After the overall laying is completed, perform concrete pouring to fill the gaps and the through holes 4 on the slab body 1.
