Its installation process is relatively cumbersome, thus prolonging the construction period.

[0004] However, there is still a problem that the above patent needs to weld the framework into one body. Therefore, in order to improve work efficiency and at the same time be able to adapt to the disassembly and installation in a variety of application scenarios, and simplify the erection steps, a precast floor component is proposed.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] See Figures 1 to 4, a floor slab precast member, comprising a number of regular hexagon precast members 1, the regular hexagon precast members 1 are connected by connectors 3, a number of connection holes 2 are provided on the regular hexagon precast members 1, and the connectors 3 are inserted into each connection hole 2; the connector 3 includes a U-shaped connecting bolt 31, an expansion tube 32 and an expansion bolt 33, the two free ends of the U-shaped connecting bolt 31 are respectively inserted into the connection holes 2 on two connected regular hexagon precast members 1, the end of the free end of the U-shaped connecting bolt 31 is provided with the expansion tube 32, and the expansion bolt 33 is clamped inside the expansion tube 32.

[0022] During the splicing process of the regular hexagon precast members 1, by inserting the connector 2 into the connection hole 3, a stable traction force is formed, so that the installation of the floor slab is more convenient and fast, and thus the construction period can be saved.

[0023] Furthermore, the sum of the length of the U-shaped connecting bolt 31 inserted into the connection hole 2 and the length of the expansion tube 32 is equal to the depth of the connection hole 2. A clamping groove 321 is provided on the inner side of the expansion tube 32, and a clamping protrusion 331 is provided on the outer side of the expansion bolt 33, and the clamping protrusion 331 is engaged with the clamping groove 321;

[0024] The U-shaped connecting bolt 31 locks the regular hexagon precast members 1 together, forming a stable traction force between two adjacent regular hexagon precast members 1. When a number of regular hexagon precast members 1 are spliced together, a stable structure is formed; when the U-shaped connecting bolt 31 is inserted into the connection hole 2 and the U-shaped connecting bolt 31 is hammered, the expansion bolt 33 expands the expansion tube 32, so that the U-shaped connecting bolt 31 is locked in the connection hole 2 and the regular hexagon precast members 1 are locked together.

[0025] Furthermore, the edge of the regular hexagon precast member 1 is of an inclined structure. After adjacent regular hexagon precast members 1 are spliced, the inclined part forms a V-shaped groove;

[0026] It can facilitate the timely drainage of water on the top of the floor slab, avoiding water seepage caused by a large amount of water accumulation on the top of the floor slab.

[0027] Furthermore, the regular hexagon precast member 1 has an upper large and lower small structure for forming a spherical structure after a number of regular hexagon precast members 1 are spliced, and a hollow groove 11 is provided on the surface of the small area end of the regular hexagon precast member 1. The hollow groove 11 can reduce the use of concrete, save materials, and at the same time reduce the overall weight of the floor slab.

[0028] Furthermore, the side surface of the regular hexagon precast member 1 is coated with an asphalt coating; after the floor slab is spliced, the asphalt coatings are fused together by heating, thereby enhancing the stability of the floor slab. At the same time, the asphalt coating does not need to be poured and cured again, which can further save the construction period and protect the regular hexagon precast member 1 from damage.

[0029] Working principle of the utility model:

[0030] In the present utility model, a number of regular hexagon prefabricated components 1 are connected to each other through connectors 3. A number of connection holes 2 are provided on the regular hexagon prefabricated component 1, and the connector 3 is inserted into each connection hole 2; then the two free ends of the U-shaped connection bolt 31 are respectively inserted into the connection holes 2 on two connected regular hexagon prefabricated components 1. An expansion tube 32 is installed at the end of the free end of the U-shaped connection bolt 31, and an expansion bolt 33 is clamped inside the expansion tube 32. During the splicing process of the regular hexagon prefabricated component 1, a stable traction force is formed by inserting the connector 2 into the connection hole 3, so that the installation of the floor slab is more convenient and fast, and thus the construction period can be saved; the sum of the length of the U-shaped connection bolt 31 inserted into the connection hole 2 and the length of the expansion tube 32 is equal to the depth of the connection hole 2. A clamping groove 321 is provided on the inner side of the expansion tube 32, and a clamping protrusion 331 is provided on the outer side of the expansion bolt 33. The clamping protrusion 331 is engaged with the clamping groove 321. After the expansion tube (32) and the expansion bolt (33) are connected, the connector (3) is effectively prevented from falling off.

[0031] The U-shaped connection bolt 31 locks the regular hexagon prefabricated components 1 together, forming a stable traction force between two adjacent regular hexagon prefabricated components 1. When a number of regular hexagon prefabricated components 1 are spliced together, a stable structure is formed; when the U-shaped connection bolt 31 is inserted into the connection hole 2 and the U-shaped connection bolt 31 is hammered, the expansion bolt 33 expands the expansion tube 32, so that the U-shaped connection bolt 31 is locked in the connection hole 2 and the regular hexagon prefabricated components 1 are locked together.

[0032] Then, the edge of the regular hexagon prefabricated component 1 is designed to be an inclined structure. After adjacent regular hexagon prefabricated components 1 are spliced, a V-shaped groove is formed at the inclined part; it is convenient for the water on the top of the floor slab to drain away in time, avoiding water seepage caused by a large amount of water accumulation on the top of the floor slab; the regular hexagon prefabricated component 1 has an upper large and lower small structure for forming a spherical structure after a number of regular hexagon prefabricated components 1 are spliced. The spherical structure can make the building structure more beautiful. At the same time, when an external force is applied to the upper side of the floor slab, mutual forces are generated between the regular hexagon prefabricated components 1, and the external force is dispersed, thereby improving the strength of the floor slab to bear the external force.

[0033] And a hollow groove 11 is provided on the surface of the small area end of the regular hexagon prefabricated component 1. The hollow groove 11 can reduce the use of concrete to save materials and at the same time reduce the overall weight of the floor slab.

[0034] The side surface of the regular hexagon prefabricated component 1 is coated with an asphalt coating; after the floor slab is spliced, the asphalt coatings are fused together by heating, thereby enhancing the stability of the floor slab. At the same time, the asphalt coating does not need to be poured and cured again, which can further save the construction period and protect the regular hexagon prefabricated component 1 from damage.

[0035] The entire device enables the floor slab to be installed without erecting a support structure during the installation process, thus making the installation of the floor slab more convenient and rapid, and saving the construction period.

[0036] The above are only embodiments of the present invention, and do not thus limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present invention.
