Technical Field
[0001] The utility model relates to the technical field of stand drainage, in particular to a prefabricated stand drainage device. Background Art
[0002] When the stadium stands adopt prefabricated stand splicing technology, the treatment of the joints is focused on preventing leakage. However, due to the influence of technology, materials and time, leakage is inevitable in the end. The research on the drainage method of this part is still insufficient.
[0003] At present, in the stadium projects that are under construction or have been built, most of them use the method of reserving drainage ditches when pouring concrete inclined beams to deal with the joints. This construction method requires waterproofing construction later. Because the drainage ditch is small and on the inclined beam, waterproofing construction has problems such as unchanged construction, low construction efficiency, and long cycle. Therefore, in view of the above phenomenon, a prefabricated stand drainage device is proposed to meet the needs of actual use. Utility Model Content

[0006] Preferably, one end of the horizontal drainage pipe close to the inner corner of the inclined beam is inserted 2-5 cm into the inner side of the step of the inclined beam.
[0007] Preferably, an anti-slip plate is fixedly installed on the inner arc surface of one end of the horizontal drainage pipe near the inner corner of the inclined beam.
[0008] Preferably, a reinforcing connecting plate is fixedly installed between the bottom of the horizontal drain pipe and the outer arc surface of the vertical drain pipe.
[0009] Preferably, the reinforcing connecting plate is a right triangle, the inclination angle of the hypotenuse of the reinforcing connecting plate is the same as the inclination angle of the oblique beam, and a slot is provided on the hypotenuse edge of the reinforcing connecting plate.
[0010] Compared with the related art, the prefabricated stand drainage device provided by the utility model has the following beneficial effects:
[0011] The utility model provides a prefabricated stand drainage device, which uses PVC drainage pipes to replace traditional drainage ditches. Due to the material of the pipes, waterproof construction after the drainage ditch is completed is saved, thereby reducing construction costs.
[0012] The utility model provides a prefabricated grandstand drainage device. In order to avoid the risk of leakage at the connection between the horizontal drainage pipe and the vertical drainage pipe, the horizontal drainage pipe is inserted into the inclined beam to avoid the hidden danger of leakage and ultimately achieve the purpose of drainage.
[0013] The utility model provides a prefabricated stand drainage device, which increases the anchoring force between the transverse drainage pipe and the inclined beam after being pre-buried by adding an anti-dropping plate, thereby ensuring the fastening effect of the pre-buried transverse drainage pipe and preventing the transverse drainage pipe from falling off after aging.
[0014] The utility model provides a prefabricated stand drainage device, which can strengthen the connection between the horizontal drainage pipe and the vertical drainage pipe by means of a reinforced connecting plate, and facilitates the fixation of the horizontal drainage pipe and the vertical drainage pipe before pre-embedding.
