Title:
NON-DRAINAGE SHEET-TYPE EXPANSION JOINT DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/191347
Kind Code:
A1
Abstract:
The present invention relates to a non-drainage sheet-type expansion joint device that can effectively improve the drainage structure between upper slabs of a bridge. The present invention is characterized by comprising: first and second finger arms (10)(10') which are provided to form expansion joints between upper slabs (1) of a bridge; a drainage plate (20) which is spaced apart from the bottom surface of the first finger arm (10) and forms a drainage passage (21), and which has an upwardly protruding upward barrier (22) provided at one end and a gap block (23) provided at the other end to prop and support the first finger arm (10); a cover plate (30) which is disposed below the second finger arm (10') and installed such that one end is fixed to the upper slabs (1) of the bridge together with the second finger arm (10'), and the other end extends up to the upper region of the drainage passage (21); and a sliding pad (60) which is made of a hard synthetic resin and pressed into close contact with the bottom surface of the cover plate (30) by the weight of the finger arm. The non-drainage sheet-type expansion joint device has an improved structure in which the drainage passage is integrally formed below the finger arm so that a drainage sheet can be excluded when using the non-drainage sheet-type expansion joint device, thus improving on-site constructability. In addition, the drainage passage can be easily and automatically cleaned by applying an air cleaning method using compressed air, and thus the device has the advantage of being easy to maintain.
