Embodiment Construction
[0020] A support device for a concrete waterproof steel plate of the present invention and its application method will be further described in detail below in conjunction with the accompanying drawings.
[0021] Such as Figure 1~3 As shown in the figure, it is a schematic diagram of the composition structure and use and installation of a support device for a concrete waterproof steel plate of the present invention.
[0022] The supporting device 1 of the concrete waterproof steel plate has two metal short pipes that can be nested together. The length of the two short metal pipes can be changed through an adjustment device arranged between them. One end of the inner pipe 9 A baffle plate 14 is welded for resisting the water-stop steel plate 2, and a stop ring 15 is welded at the end of the outer tube 8 on the same side, and the stop ring 15 can slide on the outer wall of the inner tube 9 together with the outer tube 8 , used to prevent concrete from falling into the gap betwe...

The invention provides a supporting device for a concrete water stop steel plate. The supporting device comprises two short metal pipes which can be in sleeve joint together, and total length of the sleeve joint of the two short metal pipes is changed by an adjusting device arranged between the two short metal pipes. The specific structure of the adjusting device is as follows: a section of screwis welded at one end of an inner pipe, a blocking piece provided with a center hole is welded at the end part of an outer pipe located on the same side, a nut is welded on the inner side of the centerhole of the blocking piece, the nut is matched with the screw welded on the inner pipe, and therefore, the total length of sleeve joint of the inner and outer casing pipes can be adjusted. A using method of the supporting device for the concrete water stop steel plate comprises following steps: S1, two supporting devices are placed between the water stop steel plate and a formwork and propped against the water stop steel plate and the formwork; S2, the inner and outer casing pipes in the supporting devices are twisted until the casing pipes are tightened; and S3, the screws exposed out of outer sides of E-shaped buckles are fastened by the nuts. The supporting device has beneficial effects as follows: mounting quality of the water stop steel plate is guaranteed, and mounting work efficiency is improved and higher.
Description
technical field [0001] The invention relates to a concrete waterproof construction technology, in particular to a support device for a water-stop steel plate in a horizontal construction joint of a concrete waterproof structure and a method for using the same. Background technique [0002] In concrete construction projects, underground concrete construction projects occupy a high proportion, so the waterproof structure work of underground concrete occupies an important position. In the waterproof structure construction of underground concrete, the waterproof work of horizontal construction joints is often done, but there is only one way at present, which is to vertically bury a trapezoidal groove-shaped strip steel plate at the position of the horizontal construction joints of the concrete. Then the steel plate is welded with positioning steel bars and fixed on the formwork. Due to the thinness of the water-stop steel plate, it is difficult to control the welding quality, a...
