Furthermore, the terms "first," "second," and the like are used merely to distinguish one description from another, and are not to be construed as indicating or implying relative importance.
Example one
As shown in fig. 1, a groove mold 2 for waterproofing an anti-floating anchor 1 comprises a mold body and a fixing support; the die body comprises a first inclined surface, a second inclined surface, a third inclined surface and a fourth inclined surface; the first inclined plane, the second inclined plane, the third inclined plane and the fourth inclined plane are provided with elongated holes 3; the fixed support comprises a transverse support 5 and a longitudinal support 6; the transverse support 5 and the longitudinal support 6 both pass through the two opposite elongated holes 3 and have a point of intersection inside the die body; the upper opening and the lower opening of the die body are not sealed, the die body is fixed with the transverse support 5 and the longitudinal support 6, and the transverse support 5 and the longitudinal support 6 are used for being fixed with the anti-floating anchor rod 1. The anti-floating anchor 1 in fig. 1 is arranged at the periphery of the positioning steel pipe 4. The anti-floating anchor rod 1 adopts 3 reinforcing steel bars or steel pipes with the diameter of 22mm (22 mm).
In order to solve the problem of leakage at the node of the anti-floating anchor rod 1, the invention summarizes some problems that the node of the anti-floating anchor rod 1 is likely to cause waterproof leakage in the construction process, and designs a set of groove device, thereby effectively preventing leakage risk and hidden danger in the traditional construction of the anti-floating anchor rod 1, reducing the secondary repair cost caused by leakage after the construction of the anti-floating anchor rod 1, saving resources and improving the quality of the anti-floating anchor rod 1. The invention changes the former form of pouring concrete bosses around the anchor rods, improves the structure, and has better waterproof effect of the anti-floating anchor rods 1 after the groove molds 2 are applied to the anti-floating anchor rods 1 for waterproofing. As shown in fig. 2, a schematic view is shown with the groove mould 2 arranged at a level.
Example two
And the tops of the first inclined plane, the second inclined plane, the third inclined plane and the fourth inclined plane of the die body are provided with a guard plate. The guard plate is a vertical plate or a plate inclined outwards from the die body. When backplate mainly used prevented concreting, the concrete entered into the recess, guaranteed the shaping quality of recess.
First inclined plane, second inclined plane, third inclined plane and fourth inclined plane weld in order and form, and the bottom of mould body is the rectangle opening, and the top of mould body is the rectangle opening and is bigger than the rectangle opening of bottom. If the round hole is arranged, the circular arc surface is involved, and the process is more complicated. In addition, the rectangular structure is convenient for production and manufacture of the first inclined plane, the second inclined plane, the third inclined plane and the fourth inclined plane, and the problem that the inclined planes are difficult to manufacture due to the fact that irregular openings are adopted is avoided.
The width of the rectangular opening at the bottom of the die body is at least the width of the anchor hole of the anti-floating anchor rod 1, and the rectangular opening at the bottom of the die body covers the anchor hole of the anti-floating anchor rod 1. If only a part is covered, or a part is covered by concrete, the waterproof effect is not good.
