Prefabricating and mounting method for pebble-pattern prefabricated slab

Abstract

The invention discloses a prefabricating and mounting method for a pebble-pattern prefabricated slab. The method comprises the steps that a bottom plate and a prefabricated frame with the area not larger than 1m<2> are made; graph paper is printed and is fixed to the bottom plate; the prefabricated frame is mounted on the bottom plate and surrounds the graph paper; a figure river sand layer is laid on graph paper figures; figure pebbles are laid on the figure river sand layer; a bottom river sand layer is laid on the non-figure position of the graph paper; bottom pebbles are laid on the bottom river sand layer; unqualified pebbles are replaced; a cement paste sticking layer is laid on the pebble layer; a concrete cushion is laid on the cement paste sticking layer; after the concrete cushion is cured, the prefabricated frame is removed, and 180-degree turning is carried out; the figure river sand layer and the bottom river sand layer are swept out; a cement mortar layer is brushed on the pebble layer; the pebble layer protrudes out of the cement mortar layer by 8mm to 10mm; a concrete base layer is laid; the cement mortar layer is laid on the concrete base layer; and multiple pebble-pattern prefabricated slabs are put on the cement mortar layer; and the pebble-pattern prefabricated slabs are jointed. The site operation efficiency is high, and the quality is stable.

Description

【Technical field】 [0001] The invention relates to a prefabrication and installation method of a pebble pattern prefabricated board, belonging to the technical field of landscape engineering. 【Background technique】 [0002] Pebbles are formed by cutting, eroding, flowing, scouring and grinding of running water. As landscape materials, they have a strong affinity for environmental combinations. They are often used in the design of combined patterns such as squares, courtyards, garden roads, and landscape walls. Various natural attributes enrich the artistry of its combination. In the ruins of the Mycenaean city in ancient Greece, traces of paving streets with pebbles as ground materials were found. In the gardens of the Grenada Alhamhra Palace in South America, and in the Jewish streets of Cordoba and Seville in Spain, the traditional Mediterranean pebble pavement is still preserved. . The material of pebbles is also widely used in Chinese and classical gardens. In the first...

Problems solved by technology

However, the use of soft steel sheets to set the pebble pattern increases the difficulty of welding and laying out for complex pattern textures, and the accuracy of the pattern is difficult to guarantee. In addition, the prefabricated shape is square, and the prefabricated square traces are obvious during paving, and the construction effect is difficult to guarantee.

[0008] The above existing pebble pavement construction methods are either optimized from the paste materials, and the construction technology is still the traditional process, or only the prefabrication method is used but the method of transferring and setting out the pebble pattern is not changed. The fineness of the pebble pattern pavement and quality stability are difficult to guarantee
