Description

Technical Field

[0001] The invention relates to the field of bamboo fiberboard construction technology, in particular to a seamless wall construction technology based on bamboo fiber substrate board. Background Art

[0002] With the rapid development of urbanization, scale and speed in recent years, the carbon dioxide emissions from the construction industry account for almost 50% of the total carbon dioxide emissions in my country. The construction industry is the second largest source of carbon emissions in my country. Compared with developed countries, the energy forms used in my country's buildings and the increasing energy consumption of buildings have led to high emissions of pollutants from buildings in my country, which has put great pressure on energy supply and environmental protection. The energy consumption of buildings is related to the heat obtained inside and outside the buildings. my country is in urgent need of vigorously promoting the development and application of building wall insulation technology to reduce the demand for energy consumption in buildings. In addition, the level of thermal insulation of building walls in my country is low, resulting in high energy consumption for heating and air conditioning, and low economic and social benefits. The traditional bamboo and wood fiberboard has a low secondary recycling rate due to the surface coating, which cannot effectively exert and promote its recyclable material properties. In addition, the traditional wall cloth laying method is to lay the wall cloth directly on the wall, but due to the high uncontrollable factors such as aging and moisture on the wall surface, the wall cloth will not have a long life and the labor cost of later maintenance is high.

[0003] At the 15th Conference of the Parties to the United Nations Framework Convention on Climate Change, the Chinese government solemnly promised that by 2020, my country's carbon dioxide emissions per unit of GDP will be reduced by 40% to 45% compared with 2005. The need to solve environmental problems is very urgent, and the country is vigorously promoting the healthy development of environmentally friendly and low-carbon buildings. Under the premise of low-carbon economic requirements, it consumes less natural resources and produces the least environmental pollution. However, the traditional construction model can no longer meet the requirements of sustainable development. It has become an inevitable trend for the construction industry to take the path of low-carbon, environmental protection and green development. Environmentally friendly low-carbon buildings and green buildings are the key to transforming the traditional development model of the construction industry, and are also conducive to creating a comfortable and healthy living environment. Under the guidance of the concept of sustainable development, it is imperative to reduce greenhouse gas emissions throughout the life cycle of buildings and develop environmentally friendly and low-carbon green buildings.

[0025] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-2 , the embodiment of the present invention includes:

[0027] Bamboo fiber-based panels and seamless wall coverings are prefabricated building components that can reduce material waste, improve construction efficiency, and reduce the impact of construction on the environment. The use of environmentally friendly bamboo fiber-based panels that meet the national "Environmental Label Product Requirements for Lightweight Wall Panels" and have passed the China Environmental Labeling Certification can reduce the emission of building pollutants, improve environmental quality, and reduce the impact on the environment and human health during production and use. It is also an important measure for the country to achieve environmentally friendly and low-carbon buildings.

[0028] Thermal insulation rock wool board, bamboo fiber substrate board, and wall cloth can all improve the thermal insulation performance of the wall, reduce the electricity and heat consumed during the operation phase of the building's life cycle, and not only improve the thermal insulation performance of the wall, but also reduce building energy consumption and greenhouse gas emissions. At the same time, the above three materials also have sound absorption and sound insulation properties, which can reduce the indoor sound source and the noise from the outside, reduce noise pollution, and provide users with a good, comfortable and healthy working and living environment.

[0029] In addition, bamboo fiber-based panels are easier to disassemble and can be recycled and reused. The technical solution of using recyclable green building materials is of great significance to the sustainability of the entire life cycle of the building, with good economic, social and environmental benefits, and realizing the development of a low-carbon economy.

[0030] A seamless wall construction process based on bamboo fiber substrate board adopts a set of on-site construction process of composite wall with insulation effect, which uses bamboo fiber substrate board as substrate, seamless wall cloth as finishing layer, and thermal insulation technology designed in the wall. It can solve the problem of gaps in the installation and splicing of traditional bamboo fiber integrated boards on the wall, and can also effectively reduce building energy consumption and greenhouse gas emissions. In addition, the bamboo fiber substrate board has waterproof and moisture-proof properties, which can effectively solve the problem of moisture on the wall surface, reduce the probability of mold on the wall cloth, and can significantly increase the life of the wall cloth, and increase the service life of the building and interior decoration.

[0031] Seamless wall cloths are of various types, rich in patterns, and good in texture, and can create a delicate and soft decorative effect. If the wall of the scheme of the present invention needs to be replaced with a new seamless wall cloth style later, it is only necessary to tear off the surface seamless wall cloth and re-apply a new seamless wall cloth. The basic structure of the wall can be reused repeatedly, or if the composite inner wall of the present invention needs to be demolished later, after the surface seamless wall cloth is torn off, the bamboo and wood fiber substrate board can be removed and can be recycled or reused, while reducing the generation of construction waste. Specific embodiment one:

[0033] The construction process steps of seamless wall with efficient thermal insulation effect include:

[0034] 1: Check the verticality and flatness of the wall to be constructed. The flatness deviation of the wall shall not exceed 3mm. After the construction wall is accepted, install the plumbing and electrical equipment, lay out the lines and fix the points, drill holes and glue the embedded parts or switches and sockets. Remove and clean the protruding concrete blocks, mortar and other debris on the wall. Check the appearance quality and size of all materials to be used. For bamboo and wood fiber substrates, use boards with flat seams.

[0035] 2: Set the spacing of the horizontal dividing lines on the wall at 300mm, distribute them evenly, and then pop up the horizontal dividing lines on the wall from bottom to top. Set the standard spacing of the vertical dividing lines on the wall at 400mm, and pop up the vertical dividing lines from left to right on the wall. Install wooden keels according to the horizontal and vertical dividing lines. When choosing wooden keels, you should choose wooden keels that have been treated with fire prevention, anti-corrosion and insect prevention in advance. Use nails to fix the keels horizontally and vertically according to the dividing lines. Then, the keels need to be installed independently at the edges of the inner walls of the door openings, and wooden keels are installed at the edges of the top, bottom, left, right and four sides of the wall, and wooden keels are installed at the edges of the sockets.

[0036] 3: When installing thermal insulation and sound insulation rock wool, operators should wear labor protection equipment, take good health protection, and pay attention to construction safety. Measure the spacing of the keels, use special cutting equipment to cut the thermal insulation and sound insulation rock wool board into small pieces of thermal insulation and sound insulation rock wool boards with a length of 400mm and a width of 300mm, and use a trowel to apply a layer of plastering mortar on the surface of the small piece of thermal insulation and sound insulation rock wool. The thickness of the mortar is about 2mm, and then fill the small pieces of thermal insulation and sound insulation rock wool boards into the gaps between the keels. In order to ensure that the flatness deviation of the thermal insulation and sound insulation rock wool board surface is not greater than 2mm, use a ruler to flatten the thermal insulation and sound insulation rock wool board laid on the wall at any time. If it exceeds 2mm of the keel height, remove the thermal insulation and sound insulation rock wool board and re-cut and install it or use a special grinding trowel to smooth it.

[0037] 4: Measure the wall height where the bamboo fiber base material board is to be installed, and use a special cutting tool to cut the required length of the bamboo fiber base material board. The error should not be greater than 1.5mm. Then, take the board surface of the first bamboo fiber base material board as the base surface, vertically cut off the co-extruded edge of the male end slot, apply glue on the back of the bamboo fiber base material board, and install the first bamboo fiber base material board from the left side of the wall. Use a spirit level to check the verticality, and use a rubber hammer to knock from the right to the left and the front to clamp the special stainless steel slot fastener of the bamboo fiberboard on the inside of the right female end slot of the first bamboo fiber base material board, move the special stainless steel slot fastener of the bamboo fiber up and down to a horizontal keel, fix it with self-tapping screws, and then install the special stainless steel slot fastener of the bamboo fiberboard at the intersection of the upper and lower parts of the right female end slot of the bamboo fiber base material board and the horizontal keel. Measure and cut the length of the second board according to the required wall height for installing the bamboo fiber base board, insert the male end slot of the second bamboo fiber base board into the right female end slot of the first bamboo fiber base board on the left, and knock it from right to left with a rubber hammer to make the male and female ends of the two bamboo fiber base boards completely combined at the co-extruded edges, and then evenly install the bamboo fiber stainless steel special slot fasteners again. Use this method to install the bamboo fiber base boards on the wall from left to right in sequence. When encountering the right end of the wall, door and window openings, electrical box, and socket position, the excess part of the bamboo fiber base board needs to be cut off or opened, resulting in the situation that the bamboo fiber stainless steel special slot fastener cannot be installed on one or both sides of the bamboo fiber base board. Glue needs to be applied to the back of the bamboo fiber base board for bonding, and knock it with a rubber hammer.

[0038] 5: After the overall installation of the bamboo fiber substrate board on the wall is completed, check the gaps between the joints of the bamboo fiber substrate boards, the gaps at the intersection of the bamboo fiber substrate boards and the top or the ground, and the gaps at the inner and outer corners of the wall. If the gap is greater than 1.5mm, mark the position with a marker, then fill the gypsum joints and then grind and level them. Wait for the gypsum to dry. Use a wall base membrane that has the function of resisting the smoothness of the wall surface and improving the bonding performance. It can be diluted with 20%~50% clean water, and evenly brush, roll or spray it on the surface of the bamboo fiber substrate board after sufficient stirring. The suitable construction temperature is 5~40℃, and wait for the wall base membrane to dry.

[0039] 6: Add appropriate amount of water to the glutinous rice glue according to the required proportion of glutinous rice glue. The proportion of glue should not be too thin. Use a roller or brush to evenly apply it to the surface of the bamboo fiber substrate board. The wall glue should not be too thick. Lay the seamless wall cloth on the bamboo fiber substrate board on the wall from left to right, use a soft brush to drive away bubbles from the middle to both sides, scrape the wall cloth flat and fit, and lay it in order. Use a utility knife to cut off the excess wall cloth at the upper and lower ends of the bamboo fiber substrate board, doors, windows and switch boxes, etc., wipe off the excess glue with a clean towel or foam, and lay the seamless wall cloth on the bamboo fiber substrate board in order. Finally, conduct a comprehensive inspection of the paving of the seamless wall cloth. If bubbles or bubbling are found, use a fine needle to puncture holes to release the air, and then flatten it with a towel. Specific embodiment 2:

Stick the stainless steel special slot fastener for bamboo fiberboard on the inside of the right female end slot of the first bamboo fiber substrate board, move the stainless steel special slot fastener for bamboo fiber up and down to a horizontal dividing line, fix it with an air gun, and then install the stainless steel special slot fastener for bamboo fiberboard at the intersection of the upper and lower parts of the right female end slot of the bamboo fiber substrate board and the horizontal dividing line. Measure and cut the length of the second board according to the required wall height for installing the bamboo fiber base board, insert the male end slot of the second bamboo fiber base board into the right female end slot of the first bamboo fiber base board on the left, and knock it from right to left with a rubber hammer to make the male and female ends of the two bamboo fiber base boards completely combined at the co-extruded edges, and then evenly install the bamboo fiber stainless steel special slot fasteners again. Use this method to install the bamboo fiber base boards on the wall from left to right in sequence.
