Mounting method for enhancing, expanding expansion screw bolt functions

Abstract

The present invention relates to a mounting method for reinforcing and enlarging expansion screw bolt use function, especially is a mounting method for reinforcing pulling resistance, preventing rusting, and expansion screw bolt of outside wall hang adhibit granite panel. The mounting method is that expansion screw bolt is inserted into an expanding nail hole filled with same structure glue after external diameter of expansion screw bolt is coated with structure gum without flowing, under the action between expansive power and structure gum fixing, hanging part can be installed at the tail of expansion screw bolt for matching with hole and groove on granite panel, so multiple modus mounting fixing of granite panel is realized. The beneficial effects of the present invention is a whole cylinder of expansion screw bolt with touching contact between structure gum and expanding nail hole, but no a common circular line for improving bearing ability greatly; and because expansion screw bolt is packaged by structure gum, so rust element is prevented, this can considerably prolong service lifetime, thereby mounting fixing of granite and various decoration panel is satisfied, and with utility value.

Description

Technical field: [0001] The invention relates to an installation method of an expansion bolt, in particular to an installation method capable of enhancing and enlarging the use function of the expansion bolt. technical background: [0002] In the installation and construction of existing expansion bolts, the method commonly used is to drill the expansion bolt hole on the required position earlier, so that the expansion bolts can only enter, or even enter after hitting with an iron hammer. When entering the limited depth, start the expansion device to increase the expansion head and get stuck in the expansion nail hole for fixation. However, the contact between the expanded nail head of the expansion bolt and the wall of the expansion hole is only a circular line, so softer walls such as hollow bricks or aerated concrete are not suitable for expansion bolt installation, which limits its scope of use. At the same time, because there is air in the gap between the expansion bol...

Problems solved by technology

However, at this time, the contact between the expanded nail head of the expansion bolt and the wall of the expansion nail hole is only a circular line, so relatively soft walls such as hollow bricks or aerated concrete are not suitable for installation of expansion bolts, which limits its scope of use.

At the same time, because there is air in the gap between the expansion bolt and the expansion bolt hole, the expansion bolt made of steel has the weakness of rust, so it is not suitable for the long-term and stable safety requirements of decorative panels such as granite, and there are deficiencies
