Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fixing and positioning face bricks, in particular to a bolt for fixing and positioning face bricks. Background Art
[0002] Due to the strong decorativeness, good durability, easy cleaning, and the ability to protect the wall, the tiles once became the mainstream of exterior wall decoration in the 1980s and 1990s, and also a beautiful landscape in the city. Due to the lack of advanced tile pasting technology and materials, cement mortar was generally used to paste tiles at that time. Cement mortar is made by mixing cement, sand and water, without any additives, and has limited adhesion. In particular, there is no measurement standard for cement mortar mixed on site. The construction master arbitrarily determines the combination ratio and mixes it on the ground with a shovel. There is no guarantee for construction quality and performance. Therefore, after a period of use, the tiles often appear hollow, loose, and may fall off at any time. On the one hand, the falling of tiles is unsightly, just like the wall has "psoriasis", which looks particularly uncomfortable; on the other hand, the falling of tiles is easy to injure pedestrians and vehicles, endangering the lives of pedestrians downstairs, and causing great harm to social public safety. In addition, the falling of facing tiles will cause wall cracks over time, resulting in indoor wall leakage, peeling, falling off and mildew of wall decorative paint or wallpaper, bringing many inconveniences to residents' lives. Repairs are time-consuming, labor-intensive and costly, and have become a "headache" for many residents.
[0003] Traditional brick repair generally uses the following methods:
[0004] (1) All the tiles are removed. Then the general exterior latex paint construction plan is carried out. This is time-consuming, material-intensive, and costly, and leaves a large amount of construction waste.
[0005] (2) Local repair: After removing the obviously loose and falling parts, re-tiling the tiles. This solution only treats the symptoms and not the root cause, and does not solve the overall problem.
[0006] For this reason, a solution of fixing the tiles with bolts and then waterproofing the surface came into being, and special bolts were required to reinforce the tiles. Utility Model Content
[0007] The utility model aims to provide a bolt for fixing a facing brick to solve the problems raised in the above-mentioned background technology.
[0008] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0009] A bolt for fixing a facing brick, comprising: a sleeve, an external expansion barb, an internal expansion nail and a four-sided blooming structure; the left side of the sleeve is connected with a blooming expansion tube,
[0010] The hollow part of the sleeve is a nailing hole, and a through hole is opened on the outer wall of the sleeve. One end of the external expansion barb is fixedly connected to the through hole, and the tail of the external expansion barb expands outward. The four-sided blooming structure is connected to the right side of the sleeve and is in the shape of radiating petals. The right side of the sleeve is used to drive in the internal expansion nail. The minimum diameter of the blooming expansion tube is smaller than the diameter of the internal expansion nail.
[0011] Preferably, the four-sided blooming structure is integrally arranged with the sleeve and is equally divided at ninety degrees at the right end of the sleeve for fixing the facing bricks.
[0012] Preferably, one end of the inner expansion nail driven into the casing is in a conical structure, the end of the inner expansion nail driven into the casing is used for expanding the blooming expansion tube, and the tail of the inner expansion nail is used for expanding the barbs outward.
[0013] Preferably, the blooming expansion tube is in an elliptical shape, and grooves are provided on both sides of the outer wall of the blooming expansion tube.
[0014] Preferably, the number of the through holes is two, and they are symmetrically arranged on both sides of the outer wall of the sleeve and flush with the axis of the groove.
[0015] Compared with the prior art, the beneficial effects of the utility model are:
[0016] When the bolt is used in the method of fixing the facing bricks, the inner expansion nail is driven in to expand the outer barb, so that the whole surface of the sleeve is more firmly fixed in each layer of the wall, and the bolt is fixed by the conical front end of the inner expansion nail, and the facing bricks on all four sides are fixed by the flowering structure at the front end of the sleeve, and the empty tube is filled with mortar to perfectly combine the various layers of the facing brick wall, forming the integrity of the wall, making the repaired facing brick wall strong and durable.
