Description

Technical Field

[0001] This utility model relates to the technical field of concrete double-T slab structure design, and in particular to a large-span concrete double-T slab. Background Technology

[0002] The concrete double-T slab is a high-efficiency, large-span precast reinforced concrete component. It consists of a wide panel and two tall, narrow longitudinal ribs forming a "double-T" section, combining the functions of a slab and a beam.

[0003] A search revealed Chinese patent CN206428821U, which discloses a high-earthquake-resistant, large-span prestressed concrete double-T slab. It includes a slab body and two supporting beams, with a steel reinforcement skeleton inside both the slab body and the supporting beams. The two sides along the length of the slab body are designated as side one and side two. Protrusions are spaced apart on side one, forming cavities between adjacent protrusions. Similarly, protrusions are spaced apart on side two, also forming cavities between adjacent protrusions. The shape and position of the protrusions on side one correspond to the shape and position of the cavities on side two, and vice versa. This invention, through its special structural design at both ends of the slab body, significantly improves the slab's earthquake resistance, stability, and strength, exhibiting strong earthquake resistance and fracture prevention capabilities.

[0004] Based on the above search and existing technology, the findings were as follows:

[0005] The aforementioned deceleration patent molds are highly complex, making mass production difficult and significantly increasing mold processing costs. Furthermore, the high precision requirements for on-site hoisting increase the difficulty of construction for workers and reduce work efficiency, thus presenting certain limitations. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes a large-span concrete double-T slab, which reduces construction difficulty while improving construction efficiency.

[0007] The technical solution to achieve the purpose of this utility model is: a large-span concrete double-T slab, including a double-T slab body, and further comprising;

[0008] Positioning slots, which begin around the perimeter of the double-T plate body, with a positioning block inserted into the interior of each positioning slot;

[0009] A heat insulation board is fixedly installed on the inner top of the double-T board body.

[0010] Preferably, lifting rings are fixedly installed around the surface of the double-T plate body, and support beams are fixedly installed on both sides of the bottom of the double-T plate body, with reinforcing ribs fixedly installed between the support beams.

[0011] Preferably, the bottom of the heat insulation board is fixedly installed with board body steel bars, the bottom of the board body steel bars is installed with a sound insulation board, and the sound insulation board is fixedly installed on the inner bottom of the double T board body.

[0012] Compared with existing technologies, the significant advantages of this invention are:

[0013] Firstly, this utility model enhances the load-bearing capacity of the double-T slab body by setting up supporting beams, reinforcing bars, and slab reinforcement bars. Furthermore, the vertical and staggered installation of the slab reinforcement bars inside the double-T slab body improves the seismic resistance, stability, and fracture resistance of the double-T slab body.

[0014] Secondly, the thermal insulation board used in this utility model is composed of glass wool, rock wool, and FS cement fly ash insulated roof, which has good environmental performance, good comprehensive utilization, low density, low thermal conductivity, and good thermal insulation performance. In addition, the positioning opening can be inserted into the positioning groove to ensure that the ends of the adjacent double T board bodies are flat, which facilitates installation, thereby reducing the difficulty of the workers' work and improving work efficiency.

[0015] This solution addresses the problems of existing molds being highly complex, making mass production difficult, significantly increasing mold processing costs, and requiring high precision for on-site hoisting, which increases the difficulty of construction for workers and reduces work efficiency.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] This utility model provides an improved large-span concrete double-T slab. The technical solution of this utility model is as follows:

[0024] like Figures 1-3 As shown, a large-span concrete double-T slab includes a double-T slab body 1, which has a high prefabrication rate and good fire and corrosion resistance, and also includes;

[0025] Positioning grooves 9 are located around the body of the double T plate 1. Positioning blocks 2 are inserted into the interior of each positioning groove 9, which reduces the difficulty of the workers' work and improves work efficiency.

[0026] The heat insulation board 5 is fixedly installed on the inner top of the double-T board body 1, which makes the thermal conductivity of the double-T board body 1 low and its heat insulation performance good.

[0027] Furthermore, lifting rings 8 are fixedly installed around the surface of the double T-plate body 1, and support beams 3 are fixedly installed on both sides of the bottom of the double T-plate body 1. Reinforcing ribs 4 are fixedly installed between the support beams 3. The support beams 3 and reinforcing ribs 4 further enhance the load-bearing capacity of the double T-plate. The lifting rings 8 make it easier for workers to lift the plate while ensuring stability during lifting.

[0028] Furthermore, the bottom of the heat insulation board 5 is fixedly installed with the board body steel bar 6, which improves the stability and earthquake resistance of the double T board body 1. The bottom of the board body steel bar 6 is installed with the sound insulation board 7, which is fixedly installed on the inner bottom of the double T board body 1. Through the setting of the sound insulation board 7, the double T board body 1 has a good sound insulation effect.

[0029] The specific working method is as follows: During hoisting, the lifting device is installed on the lifting ring 8, and then the crane is controlled to slowly lift the double T plate body 1. After reaching the designated position, the double T plate body 1 is slowly lowered. The positioning block 2 is aligned with the positioning groove 9 of the previous double T plate body 1 so that the positioning block 2 is inserted into the positioning groove 9. Then the hoisted double T plate body 1 is lowered. After being lowered, the ends of the two adjacent double T plate bodies 1 are flat, thereby reducing the difficulty of the workers' work and improving the workers' work efficiency.

[0030] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
