Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of ceramic brick guardrail installation, and particularly relates to a construction method of a ceramic brick panel cantilever type guardrail. BACKGROUND

[0002] The guardrail is a kind of building structure for safety protection and decoration, which is used for enclosing and protecting the edges of balcony, staircase, corridor and the like to prevent people from accidentally falling. The current mainstream guardrail structures include three kinds of traditional masonry type guardrail, metal frame + filling plate type guardrail and prefabricated concrete hanging plate guardrail, which can realize the protection function, but all have the following problems: The traditional masonry type guardrail is integrally built by bricks or concrete, has a heavy structure and needs foundation support, has a large self-weight, and is high in load requirement for the building structure; the construction period is long, needs on-site wet work, and is poor in environmental protection; the shape is single, and it is difficult to realize the light aesthetics pursued by modern buildings.

[0003] The metal frame + filling plate type guardrail takes steel structure / aluminum alloy as a skeleton, fills glass, metal plate or wooden plate, and is commonly seen in modern buildings, but the metal skeleton is easy to corrode (especially in coastal or high humidity environment), and is high in maintenance cost; rigid connection causes stress concentration, and the welding seam or bolt is easy to loosen after long-term use; the filling plate relies on external fixing members, and there is redundant support structure in vision.

[0004] The prefabricated concrete hanging plate guardrail suspends the concrete plate on the main structure through a pre-embedded part, reduces part of the weight, but the plate thickness is large (usually greater than or equal to 80 mm), and the root bending moment is significant when cantilevered; an additional decoration layer (such as paint, veneer) is needed on the surface, and the comprehensive cost is high.

[0005] As can be seen, the existing guardrail structures generally face the contradiction between "structural redundancy" and "aesthetic simplicity", and the above technical problems have not been solved, and the application designs a ceramic brick panel cantilever type guardrail. SUMMARY

[0011] Further, the specific process of step 6 is as follows: The ceramic tile with a mounting hole is sequentially hung on the ceramic tile steel pipe from bottom to top, and the adjacent two ceramic tiles are separated by a spacer; when the ceramic tile is installed to the top layer, the installer first places the ceramic tile and temporarily holds it with his hand to ensure that the centers of the holes on the ceramic tile and the ceramic tile below are on the same vertical line, and then a long pin is sequentially inserted through the upper layer of steel plate, the ceramic tile on the top layer, and the spacer until the long pin is inserted into the limiting block in the ceramic tile steel pipe, so that the entire ceramic tile steel pipe is fixed.

[0012] Further, the specific process of step 7 is as follows: The outer package decoration profile is placed on the upper layer of steel plate, and the outer package decoration profile and the upper layer of steel plate are separated by a spacer and rubber skin, then the outer package decoration profile is fixed on the upper layer of steel plate from below the upper layer of steel plate by using a bolt, and the bolt is hidden by installing a decoration profile cover below, the outer package decoration profile is closed, and then the gap between the outer side of the outer package decoration profile and the upper layer of steel plate is sealed by using sealant.

[0013] Further, the specific process of step 5 is as follows: First, the outer packaging decorative profile of the column is installed, and then the lower galvanized steel pipe of the transverse framework and the outer packaging decorative profile of the middle steel plate are installed; flexible gaskets are used to separate the contact parts of the steel materials during the installation of the outer packaging decorative profile to prevent bimetallic corrosion.
