Steel structure surface brick pavement construction method

Abstract

The invention discloses a steel structure surface brick pavement construction method. The method comprises the following steps: galvanized iron wire nets A (2) and galvanized iron wire nets B (3) cover the surfaces of steel columns (1); the galvanized iron wire nets B (3) are vertically pressed from the external by using reinforcements (4); the galvanized iron wire nets A (2), the galvanized ironwire nets B (3) and the reinforcements (4) are welded on the steel columns (1) by each other 400-600 mm through arc welding; cement mortar A (5) is used for plastering and totally wrapping the galvanized iron wire nets A (2), the galvanized iron wire nets B (3) and the reinforcements (4); and the finished surface of the cement mortar A (5) is higher than the highest point of the reinforcements (4)by 8-12 mm to guarantee the levelness of base layers of the cement mortar A (5). After the base layers of the cement mortar A (5) are hardened, cement mortar B (6) can be plastered on the surfaces ofthe cement mortar A (5) for pavement of surface bricks (7). The method is low in cost, not easy to slide, convenient to operate, high in working efficiency, low in construction cost, safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a construction method for laying bricks on the surface of a steel column. Background technique [0002] Because the steel structure has many advantages such as light weight, small size, high strength, fast construction speed, and excellent seismic performance, it is widely used in construction engineering. Steel columns and steel pipe columns of various shapes are very common in daily life. Due to steel columns, Most of the decorations on the exterior of steel pipe columns are sprayed with paint, which is easy to fall off and change color after being exposed to the sun and rain, and the method is single and lacks texture. Most of the projects adopt the steel structure system, and then add steel keel hanging bricks and stone materials outside the steel columns and steel pipe columns. However, in the dry hanging process, there are many parts such as skeletons, hang...

[0002] Because the steel structure has many advantages such as light weight, small size, high strength, fast construction speed, and excellent seismic performance, it is widely used in construction engineering. Steel columns and steel pipe columns of various shapes are very common in daily life. Due to steel columns, Most of the decorations on the exterior of steel pipe columns are sprayed with paint, which is easy to fall off and change color after being exposed to the sun and rain, and the method is single and lacks texture. Most of the projects adopt the steel structure system, and then add steel keel hanging bricks and stone materials outside the steel columns and steel pipe columns. However, in the dry hanging process, there are many parts such as skeletons, hanging parts, and clips, which greatly increase the amount of steel used. The area of ​​a single stone block is small, and there are many hanging parts, clips and other parts added, which is uneconomical. However, it is easy to fall off when directly laying veneer bricks on the steel column and steel pipe cylinder surface. The surface of the upper steel structure is relatively smooth after derusting, which leads to the weakening of the adhesion between the brick paving mortar and other adhesives and the steel column and steel pipe column. The work efficiency is low, the construction cost is high, and a certain degree of dry shrinkage will occur during the hardening process of the mortar, which will weaken the adhesion between the mortar and the steel column and steel pipe column, and cause gaps and hollows between the surface of the steel column, steel pipe column and mortar, and Outdoor steel columns and steel pipe columns are exposed to the sun and rain for a long time and affected by temperature changes, causing repeated thermal expansion and contraction, the thermal expansion coefficients of steel and facing brick mortar and other bonding materials are inconsistent, and the paving bricks, steel columns, and steel pipe columns are peeled off from the attachment surface , under the action of the brick’s own weight, the peeling speed intensifies, and finally a large area is peeled off, detached, and landed, resulting in project repair, poor project quality, easy to fall off and hurt people, and there are potential safety hazards
