The size of each piece ranges from 300 mm × 300 mm to 500 mm × 500 mm. Can use thin board and 1:2 cement mortar mixed with 107 glue for paving. Stone floor refers to natural granite, marble, artificial granite, marble and other floors. 1. Stone floor decoration structure The stone used on the indoor floor is generally polished board with a thickness of about 20 mm. There are also thin boards with a thickness of about 10 mm, suitable for home decoration. The size of each piece ranges from 300 mm × 300 mm to 500 mm × 500 mm. Can use thin board and 1:2 cement mortar mixed with 107 glue for paving. Second, the basic process flow of stone floor decoration Cleaning and finishing the base level floor→leveling with cement mortar→setting the elevation and elastic line→selecting material→soaking the board with water→installing standard blocks→paving cement mortar→paving stone→grouting→cleaning→maintenance. Three, construction points The treatment of the base layer should be clean, and the unevenness should be flattened and repaired first. The base layer should be clean and free of mortar, especially white mortar ash, oil stains, etc., and moisten the ground with water. When paving stone and porcelain tiles, standard blocks must be placed. The standard blocks should be placed at the intersection of the cross lines and installed diagonally. When paving operation, each line should be hung in sequence. The stone must be soaked in water and dried in the shade and wipe the backside. The maintenance of the stone and porcelain tile floor after paving is very important. It must be sprinkled with water 24 hours after installation, and covered with sawdust after paving. Four, matters needing attention (1) Before paving, try to assemble the boards, match the flowers, colors, and numbers, so that the patterns on the ground are the same. (2) The stone must be soaked in water and dried in the shade. So as not to affect its hardening, hollowing, shelling and other problems. (3) After the paving is completed, no one will be allowed for 3 days.

Use stone mosaic technology to make beautiful natural stone paintings

石材拼花，其实可以看做是马赛克工艺的一种发展和延伸，是马赛克工艺和新的加工工艺和技术相结合的而衍生出的新的石材产品。像早期的石材拼花，主要是石材板材类产品的拼组，这可以看成是放大版的石材马赛克，而后期由于水刀技术的应用和加工精度的提升，石材拼花把马赛克的镶嵌工艺发挥到了极至，形成了自己独特的风格。不过在国外石材拼花还是属于石材马赛克的范畴的。

Technical requirements for granite industry

Technical requirements for granite industry

The industrial technical requirements for granite have different focuses due to different uses. 1. The main requirements for natural granite blocks: The main requirements of the building materials industry standard (JC-204-92) for natural granite blocks are as follows: The blocks must have the shape of a right-angled parallelepiped. The large surface of the block should be parallel to the joint surface or pattern direction of the rock. The size of the block requires a length greater than or equal to 140cm, a width greater than or equal to 60cm, and a height greater than or equal to 60cm. Appearance quality requires that the hue, pattern and grain structure of the same batch of blocks should be basically the same. The quality requirements for the missing corners, missing edges, cracks, color lines and stains of the blocks shall meet the requirements of Table 4.24.6. Physical performance requirements: density not less than 2.50g/cm3; water absorption not more than 1.0%; dry compressive strength not less than 60.0MPa; bending strength not less than 8.0MPa. 2. Quality requirements for acid and alkali-resistant granite: (1) Quality requirements for acid-resistant granite Main chemical composition requirements: SiO2>70%～75%, the higher the content, the better the acid resistance; Al2O3>13%～15%; Fe2O3<0.5%; CaO<0.8%; MgO<0.4 %; Acid resistance is greater than 97.5%. hard. The thermal resistance (compressive strength after 10-40 thermal changes) is greater than 16.2MPa, the melting point is 1610°C, the expansion coefficient is less than 8×10-3, and the water absorption is less than 1.5%. (2) The quality requirements of alkali-resistant granite require high CaO and MgO content. The higher the content, the better the alkali resistance. Some acid-resistant stones have high SiO2 content, but have low porosity and can also be used as alkali-resistant stones. The chemical composition of the alkali-resistant granite products produced by Qingdao Liushi General Factory is as follows: SiO276.6%, Al2O314.39%, (K2O+Na2O)9.07%, Fe2O31.14%, CaO1.34%, MgO0.68%.

Dry Hanging Process and Quality Control of Stone Exterior Wall

Dry Hanging Process and Quality Control of Stone Exterior Wall

Abstract: The construction technology of the dry hanging (sticking) process of decorative engineering stone is relatively difficult. The dry hanging (sticking) construction is a new type of decoration that uses high-strength corrosion-resistant connection rings to install and fix the decorative stone on the surface of the building's exterior wall. The construction process, construction technology requirements are high and the operation is relatively difficult. To make stone decoration achieve the expected quality goals, it must be strictly controlled to affect its construction quality. This article combines engineering examples, conducts research and analysis, and introduces the construction technology of stone dry hanging and the key points of quality control. 1 Introduction With the continuous development of the economy, we have come into contact with more and more engineering projects, such as courts, procuratorates, commodity inspection, radio and television centers, etc., all of which are public buildings with dozens of floors and dozens of floors. The main building (or skirt Natural stone (granite stone) curtain wall is used for the decoration of the outer protective structure of the building and the inner wall (column) of the first floor. The decoration of stone curtain wall or the combination of stone curtain wall and glass curtain wall makes the whole building produce a strong contrast between virtual and reality, harmonious colors, unique style, solemn and elegant visual effects, adding splendor to the city. Same as glass curtain wall project. The factors affecting the construction quality of stone curtain wall engineering are also multifaceted. The five factors of human, machine, science, law and environment have a comprehensive impact on construction quality. However, due to the particularity of stone and its dry hanging structure, its construction method and process quality influencing factors and quality control focus are different. Practice has shown that, according to the structural characteristics of the building, the requirements of the design and specifications, and the company's own technical strength, the corresponding construction technology is formulated and strictly implemented. Doing a good job of supervision and inspection is an important part of the foundation of construction technology management and quality control of stone curtain wall engineering. Combining engineering examples and taking the construction of a certain building curtain wall as a reference, the author makes some discussion on the construction technology of stone dry hanging and its quality control points. 2. Project overview The frame-shear structure of a certain building has one basement floor, 16 floors above ground, and a height of 71m; a three-story podium with a total construction area of 37,781 square meters. The construction unit requires curtain wall decoration for the main building and the outer walls of the podium. Except for the glass curtain wall in the middle of the main building's front and back facades, the rest (including the decorative lines in the glass curtain wall) are all granite curtain walls. The granite slabs on the outer walls and the first floor cover an area of approximately 11,300 square meters. The stone curtain wall project is constructed by dry hanging method; the construction process, key parts, key procedures and construction difficulties are strictly controlled throughout the construction process. 3. Construction technology 3.1 Construction process Set up external scaffolding to measure and set the line → install the steel structure frame → formulate the arc sleeve model template → granite drilling → install the stainless steel support and granite slab → adjust and correct, check the verticality and smoothness → the same set at the edge of the seam Masking tape → applying sealant → removing the tape, cleaning, waxing → removing the shelf → cleaning the site. 3.2 Rack requirements The clear distance between the vertical pole and the wall is not less than 400mm, anchored with the main structure, the upper end is the same as the parapet, the middle is anchored with the floor column, the shelf is covered with safety protection boards, and the outside is protected by dense mesh nets. 3.3 Measuring and setting out Measurement and setting-out is an important part of this stone dry hanging construction. Pay-off accuracy. Directly affect the effect of stone dry hanging. Therefore, the laying method determines the size of the construction error. We require the construction unit to check the laying off from these aspects: (1) This project first needs to release the control line. Before the control line is cast, it is necessary to carry out the lead: that is, the original main structure axis and elevation, when the control line is cast on the floor, the center line of the building must be found first, and then cast in two directions, which can eliminate 50% cumulative er
