Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a waterproof center-joint strip for fixing an exterior wall decorative plate of an existing building. Background Art

[0002] Exterior wall decorative panels are new integrated building exterior wall decoration and insulation materials developed in recent years. They are mainly used for exterior wall decoration and energy-saving renovation of various buildings such as gymnasiums, libraries, school and hospital office buildings, villas, etc.

[0003] During the installation of the existing exterior wall insulation decorative integrated panels (hereinafter referred to as "integrated panels"), the integrated panels are fixed to the wall by special glue and anchor fasteners, and the adjacent integrated panels are waterproofed and fixed by artificially injecting the special glue of the product. The traditional technology of waterproofing and fixing the adjacent integrated panels by artificially injecting the special glue of the product has the following major disadvantages:

[0004] 1. High construction cost: On the one hand, the traditional method uses a large amount of special glue for this product, which makes the material cost higher; on the other hand, in the traditional method, the step of injecting special glue in external construction takes a long time and before injecting the special glue, it is necessary to stick masking tape on the edge of the integrated board to prevent contamination of the integrated board surface, which in turn increases material and labor costs.

[0005] 2. Limited service life and poor waterproof ability: In traditional technology, adjacent integrated panels are fixed by injecting special glue. In cold areas where integrated panels are popular, this operation can easily lead to cracks at the joints, which in turn causes problems such as water seepage, poor weather resistance, and a short service life.

[0006] 3. Poor stability and poor appearance: During the construction process under traditional technology, due to the unevenness of the wall and other reasons, adjacent integrated panels are prone to uneven surfaces, which not only reduces the overall stability but also affects the overall appearance.

[0007] 4. The technical requirements of the constructors are high: the risk of outdoor construction is increased: the adjacent integrated panels are completed by manually injecting special glue, so the technical requirements of the constructors are very high. Not only does it require the horizontal and vertical beauty after the special glue is injected, but also the injection amount must be appropriate. Too little will result in poor waterproof performance, and too much will increase costs and cause pollution. On the other hand, this technology will increase the time of outdoor high-rise construction, which invisibly increases the risk of construction. Utility Model Content

[0008] The utility model aims to provide a waterproof center joint strip for fixing the exterior wall decorative panels of existing buildings, so as to solve the problems raised in the above-mentioned background technology.

[0009] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a waterproof center-joint strip is fixed on the exterior wall decorative panel of an existing building, comprising a fixed back plate, an extension plate is fixedly installed on the bottom of the fixed back plate, and a water retaining back plate is fixedly installed on the bottom of the extension plate on a side away from the fixed back plate, an intermediate connecting plate is fixedly installed on the center position of a side of the water retaining back plate away from the fixed back plate, and a fixed baffle is fixedly installed on the side of the intermediate connecting plate away from the water retaining back plate.

[0010] Preferably, an upper groove is formed between the top of the middle connecting plate and the water retaining back plate and the fixed baffle, and a lower groove is formed between the bottom of the middle connecting plate and the water retaining back plate and the fixed baffle.

[0011] Preferably, a plurality of fixing holes are equidistantly spaced apart on one side of the fixed back plate, and fixing bolts are installed in the fixing holes, and a blocking piece is connected to the outer shell of the fixing bolt.

[0012] Preferably, the fixed back plate, the extension plate, the water retaining back plate, the middle connecting plate and the fixed baffle are all made of aluminum alloy.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. Low construction cost. It is inserted into the integrated board during the production process and only needs simple fixing during installation, which makes the product cost-effective and low in construction cost.

[0015] 2. Made of aluminum alloy, it has low depreciation rate and long service life.

[0016] 3. The utility model can prevent rainwater from penetrating, solves the problem of water seepage in the external wall for many years, and has good waterproof performance.

[0017] 4. Good stability and beautiful appearance: During the installation process, because the construction effect of this product is similar to the "H" type structure, there is no height difference problem between the upper and lower adjacent integrated panels, which perfectly solves the problem of unevenness and poor stability of adjacent integrated panels caused by uneven walls, and enhances the stability between integrated panels. At the same time, the increase in flatness also improves the overall appearance. BRIEF DESCRIPTION OF THE DRAWINGS
