Description

Technical Background

[0001] The invention belongs to the field of bamboo material processing and application, in particular to a method for preparing an earthquake-resistant house by using bamboo material composite modified gypsum and wall modules. Background Art

[0003] At present, most civilian houses are built with cement, reinforced brick and concrete structures. The idea of ​​"using steel to overcome steel" to measure earthquake intensity dominates the construction of earthquake-resistant houses. my country has a vast territory and many places are in earthquake zones. The longitudinal wave amplitude and transverse wave shear force brought by earthquakes cause houses to shake up and down, left and right, or back and forth, which is the main reason for house collapse. The Forbidden City has survived earthquakes for more than 600 years. It uses a lot of wood and bracket mortise and tenon structures, which allow houses to shift slightly during earthquakes. The wooden columns and wooden components have not decayed for hundreds of years. The use of the hemp knife wrapping technology is like putting armor on the wood, which is a model of "soft overcoming hard" earthquake-resistant housing. The scarcity of wood today determines that wood can no longer be the mainstream of civil construction. my country's abundant bamboo resources are sustainable resources. It is rare to use the resilience of bamboo for earthquake-resistant housing. Compared with steel, bamboo of the same diameter has slightly lower tensile strength, but stronger resilience than steel. The disadvantage of bamboo is that it is easy to breed insects and mold in a humid environment. Bamboo is compounded with high-alkaline materials such as cement concrete. Over time, the lignin and hemicellulose in the bamboo will decompose under the action of alkali, thereby reducing the strength of the bamboo. For example, high-temperature carbonization is often used for bamboo insect prevention, and a large amount of organic matter inside the bamboo will be lost, which is not conducive to the resilience of the bamboo. The present invention uses a "smoke and fire" method at a medium temperature of 60-90 degrees. It takes 4-6 hours to allow tar to smoke and penetrate into the bamboo for insect prevention, and lightly carbonize it to a moisture content of 15%-20%. After the bamboo is soaked with cooked tung oil, combined with modern material processing technology, the resilience of the bamboo is protected and its durability is increased. The following schemes are adopted: 1: Conventional Polyurethane low-foam resin or isocyanate glue has a neutral alkalinity. Its hardness, flexibility, adhesion, waterproofness, sealing, and fluidity are well combined with bamboo. It can be applied on the surface of bamboo as a secondary protective layer. 2. Gypsum has a neutral alkalinity. It is brittle, has limited bonding strength, poor flexibility and waterproofness, and needs to be modified. Use 100 parts of gypsum, 10-20 parts of acrylic emulsion, 10-15 parts of styrene acrylic emulsion, 3-5 parts of bamboo fiber, 0.3-0.5 parts of water reducer, 0.1-0.3 parts of defoamer, and 0.1-0.3 parts of bamboo and 35-40 parts of water are mixed into modified gypsum slurry; the technical route of the present invention is: bamboo is used to prepare bundled bamboo reinforcement and double-headed dovetail joints, which are molded into wall modules with longitudinal holes in the middle, transverse grooves and wall seam supporting mortise and tenon joints on both sides, and vertical dovetail joints on the inner surface, and double-headed dovetail joints are used to plug into a hollow layer, which is filled with foam insulation material to form an integrated wall module; on the foundation layer at the construction site, the wall modules are used to build the wall with staggered joints and holes up and down, and bundled bamboo reinforcement is placed in the transverse grooves and inserted into the longitudinal holes, and modified The trapezoidal foundation modules and wall modules are injected with flexible gypsum slurry, and the horizontal grooves, longitudinal holes and wall seams are filled. The first layer wall modules and bracket modules are injected with polymer flexible glue to form earthquake-resistant walls. The light steel bamboo bow gable roof is fixed with the bundled bamboo reinforcement on the bracket module to prepare earthquake-resistant houses with bamboo composite modified gypsum and wall modules. Its benefits are: 1. When an earthquake occurs, the polymer flexible glue and the bundled bamboo reinforcement in the foundation first layer wall module and the top bracket module are flexible pins, which can allow the wall and roof to move slightly to resist the wall The deformation of the body and roof, the shear resistance of the longitudinally bundled bamboo bars, the pin-key force of the modified gypsum and the longitudinally and transversely bundled bamboo bars on the wall modules, and the supporting force of the double-headed dovetail joints on the inner and outer wall modules, the synergy of these three forces plus the lightweight roof helps the house to be "not broken when it is shaken and not collapsed"; 2. The light steel bamboo bow gable roof can be installed with distributed photovoltaic power generation. The bamboo bow imitation Han tile roof is particularly suitable for composite solar flexible power generation film, connected to the home DC power supply and energy storage system, to complete the self-generation and self-use of the surplus power to the grid, and cooperate with DC appliances to achieve near zero energy consumption; 3. At the construction site In this case, modified gypsum slurry is injected into the longitudinal holes and seams of the wall modules to achieve bonding between them, eliminating the traditional manual cement mortar laying method. This saves labor costs and improves construction efficiency. Furthermore, the wall modules reduce the weight of the house, reducing construction and transportation costs. Fourthly, in the wall modules, modified gypsum slurry is injected into the wall modules to wrap the transverse and longitudinal bundled bamboo reinforcements. In the event of a fire, the gypsum loses its crystallization water to form reinforced bamboo core gypsum columns to support the roof, mitigating the risk of disasters. Summary of the Invention
