The present application is described in further detail below in conjunction with figures 1-5.
The embodiment of the application discloses a connection structure of prefabricated roofing. Referring to fig. 1 and 2, the connecting structure of the prefabricated roof comprises a prefabricated roof panel 1, a roof beam 2, a connecting sleeve 3 and a connecting rod 4, wherein the connecting sleeve 3 is pre-buried in the prefabricated roof panel 1, the connecting sleeve 3 is in a circular tube shape, and one end of the connecting sleeve 3 is in a closed arrangement. The opening direction of the connecting sleeve 3 is vertically downwards, and the opening surface of the connecting sleeve 3 is flush with the lower side wall of the prefabricated roof panel 1. The connecting rod 4 part is pre-buried in the up end of roofing roof beam 2, and connecting rod 4 perpendicular to roofing roof beam 2's up end. The prefabricated roof boarding 1 is erected on the upper end face of the roof girder 2, and the connecting sleeve 3 is sleeved on the connecting rod 4.
Referring to fig. 1 and 2, an exhaust pipe 31 is fixedly connected to the top wall of the connection sleeve 3, the central axis of the exhaust pipe 31 is perpendicular to the central axis of the connection sleeve 3, and the exhaust pipe 31 is communicated with the connection sleeve 3. The side wall of the connecting sleeve 3 is fixedly connected with a grouting pipe 32, the axis of the grouting pipe 32 is perpendicular to the axis of the exhaust pipe 31, and the grouting pipe 32 is communicated with the connecting sleeve 3. The exhaust pipe 31 and the grouting pipe 32 are both pre-buried in the prefabricated roof board 1, and the grouting pipe 32 and the exhaust pipe 31 are both communicated with the external space of the prefabricated roof board 1.
When the prefabricated roof panel 1 is lifted to and put on the roof beam 2, the connecting sleeve 3 is sleeved on the connecting rod 4, cement mortar is poured into the connecting sleeve 3 through the grouting pipe 32, and air in the connecting sleeve 3 is discharged through the exhaust pipe 31, so that the inside of the connecting sleeve 3 can be filled with the cement mortar. The exhaust pipe 31 is arranged on the top wall of the connecting sleeve 3, so that the cement mortar cannot block the exhaust path of the exhaust pipe 31 before filling the connecting sleeve 3.
When the cement mortar is cured, the cement structure enables the connecting rod 4 to be firmly connected to the connecting sleeve 3, so that the prefabricated roof panel 1 can be firmly mounted on the roof beam 2. Compared with the welding of two pre-buried steel plates, the requirement of pouring cement mortar into the connecting sleeve 3 to the field is lower, the connecting sleeve can be suitable for high-altitude operation, and can be poured and installed in rainy days, so that the installation efficiency of the prefabricated roof panel 1 is relatively higher.

After the connecting rod 4 and the connecting sleeve 3 are fixed, the prefabricated roof panel 1 can be more firmly connected to the roof beam 2, and the possibility that the connection stability of the prefabricated roof panel 1 and the roof beam 2 is affected due to strong wind blowing is reduced.
Referring to fig. 2, in order to further enhance the connection stability between the prefabricated roof panel 1 and the roof girder 2, a plurality of reinforcement teeth 41 are fixedly connected to the portion of the connection rod 4 located in the connection sleeve 3, and a plurality of reinforcement teeth 41 are distributed on the side wall of the connection rod 4 in an array.
The plurality of reinforcing teeth 41 can increase the connection strength of the connecting rod 4 with the cement structure to enhance the connection strength of the connecting rod 4 with the connecting sleeve 3 and the prefabricated roof panel 1, further reducing the possibility of affecting the connection stability of the prefabricated roof panel 1 with the roof girder 2 due to strong wind blowing.
Referring to fig. 2 and 5, when a strong wind or an earthquake occurs, the roof beam 2 and the prefabricated roof panel 1 are relatively displaced, resulting in bending or breaking of the connection rod 4, thereby affecting the connection stability of the roof beam 2 and the prefabricated roof panel 1. The top surface of roof beam 2 pre-buried has a positioning tube 6, and positioning tube 6 is the tubulose, and the one end of positioning tube 6 is the closed setting, and the opening direction of positioning tube 6 is vertical upwards to be set up. The connecting rod 4 is arranged on the bottom wall of the positioning cylinder 6 in a penetrating way.
Referring to fig. 2 and 5, an insertion tube 7 is fixedly connected to the opening edge of the connecting sleeve 3, and the insertion tube 7 is inserted into the positioning cylinder 6. A first sealing paste layer 8 is arranged between the pipe wall of the insertion pipe 7 and the inner wall of the positioning cylinder 6. The first layer of sealing paste 8 is disposed around the central axis of the positioning cylinder 6.
The plug tube 7 is inserted in the positioning cylinder 6, when cement mortar is poured into the connecting sleeve 3, the cement mortar can flow into the positioning cylinder 6 and the connecting sleeve 3 to be solidified to form a cement structure, so that the strength of the connecting rod 4 is further enhanced, the bending or fracture possibility of the connecting rod 4 is reduced when the prefabricated roof panel 1 and the roof beam 2 slightly displace relatively, and the connection stability of the prefabricated roof panel 1 and the roof beam 2 is further improved.
The first sealing paste layer 8 seals between the pipe wall of the insertion pipe 7 and the inner wall of the positioning cylinder 6, so that rainwater is not easy to flow into the cement structure in the insertion pipe 7 through between the outer wall of the insertion pipe 7 and the positioning cylinder 6 and seeps through the cement structure to rust the connecting rod 4, the strength of the connecting rod 4 is affected by rainwater infiltration is reduced, and the possibility that the connection of the prefabricated roof panel 1 and the roof beam 2 is unstable is caused.
The implementation principle of the connection structure of the prefabricated roof provided by the embodiment of the application is as follows: when the prefabricated roof panel 1 is lifted to and put on the roof beam 2, the connecting sleeve 3 is sleeved on the connecting rod 4, cement mortar is poured into the connecting sleeve 3 through the grouting pipe 32, and air in the connecting sleeve 3 is discharged through the exhaust pipe 31, so that the inside of the connecting sleeve 3 can be filled with the cement mortar. When the cement mortar is cured, the cement structure enables the connecting rod 4 to be firmly connected to the connecting sleeve 3, so that the prefabricated roof panel 1 can be firmly mounted to the roof girder 2.
Compared with the welding of two pre-buried steel plates, the requirement of pouring cement mortar into the connecting sleeve 3 to the field is lower, the connecting sleeve can be suitable for high-altitude operation, and can be poured and installed in rainy days, so that the installation efficiency of the prefabricated roof panel 1 is relatively higher.
And connect fixedly connecting rod 4 and connecting sleeve 3 through cement structure, the steel construction does not expose outside, consequently need not to apply paint to the steel construction, also need not to spend time and money and to apply the fender to the application, practiced thrift the installation cost to prefabricated roof boarding 1.
