| Building energy consumption is about30-40%of a country’s total energy consumption. Effectively reduce building energy consumption are becoming increasingly scarce energy today has a very important practical significance,Green prefabricated concrete building, the housing industry and the industrialization of construction has become an irreversible trend in the construction industry,Energy-saving building materials has also become the focus of world construction industry is committed to research and development.This paper presents the design of a prominent energy efficient, fireproof, waterproof and sound insulation performance, hardcover integration, slats chemical plant prefabricated production and the scene quickly plug the construction of the exterior wall the prefabricated insulation slats system-HRP exterior wall slats systemthe concept of HRP exterior slats basic design and performance analysis and optimization and industrialization production technology.The HRP strip wall of the plate body along the direction of the thickness thereof is set of the inner panel, outer panel and is located in the outer panel, the inner panel between the core sheet and the outer panel, the inner panel between the Heat Broken Bridge structural member connection as a whole, to preventthe emergence of a "cold bridge". Between the two plates embedded a continuous sealing silicone strip, can block the exchange of outside air and room to reduce the loss of heat. By calculating the thermal resistance value of the slats is2.922m2·K/W, the heat transfer coefficient compared to0.342W/(m2·K), reached more than75%of the energy efficient targets. HRP wall panels board type and size, wallboard panel mortar, wallboard structure and production process optimization design, to match factory industrial production needs, and can be used intelligent production line, large-scale, standardized production, a significant reduction in production costs. On the the plate board type and size to optimize the design, its width600mm, thickness and length can be adjusted, and a reasonable layout design as simple as possible, set aside a certain amount of manufacturing and construction deviation. Test developed by a balanced better liquidity and high strength mortar, sand particle size distribution were studied, early strength agent, superplasticizer dosage Mortar analysis by orthogonal test results select the best ratio of each component in the additives sulphoaluminate of cement:PO42.5:defoamer:superplasticizer:boric acid:cellulose ether: early strength agent=100:300:0.1:3:0.1:0.05:8.Using a fire closed polystyrene board to do the insulation layer material, polystyrene board reserved1-2mm compression space along the width direction, and surrounded by reserved space of30mm×57mm polystyrene board substrate paste modified phenolicfire board. Slats fire rating improves fire blocking design; at the same time will not produce heat broken bridge.HRP slat wall on both sides of the tenon and mortise wateiproof construction, the vertical seam into horizontal fractures, tenon and mortise waterproof structure is tilted45°diamond-shaped beveled, set on an incline diversion tank once the flood water from entering like tile roofthe same water can be quickly exported; and on the slats along, following along both supporting the slope is very conducive to waterproof; located around the slat ends and two seals, but also conducive to waterproof.Set HRP exterior slats around two sealing strips for wall sealing, and batten construction after pouring a sealing material in places connected with the beam. Article sound insulation performance analysis and calculation, the amount of standard board insulation58.85dB, sound insulation performance is very prominent.HRP exterior slats themselves to achieve a set of thermal insulation, fire protection, water, refined decoration in one, and reserve the appropriate size deviation plate body, used the industrialized high accuracy to meet the low accuracy of the on-site construction, board hoisting plug assemblyin place, construction is fast and convenient. The true stone class coatings and Futan of class external finishes diversification to need to customize according to the project.0.5to1mm gap, in the longitudinal direction of the plate in the width direction of the plate reserved reserved3～5mm gap, and should be adopted when the construction the "Winter left seam, summer top tight manner so that the size of the slit is reserved more reasonable.Mortar meet the performance requirements of the HRP slat wall panel and panel φ2@40mm steel mesh preparation, slat structure is more reasonable force. Developed a the panel dedicated fiber mortar, the panel size from50mm down to30mm, greatly reducing weight; plate length3600mm standard board, for example, the internal force calculation and analysis of the use phase and construction phase, based on the control of internal forces of the dangerous section checking φ2@40mm, steel mesh reinforcement requirements.In the case of the test site, according to the trial, the preliminary ideas designed HRP exterior slats fully automated production lines, Production steps work points as well as the production of packaging, storage and other considerations, to meet the industrialization and standardization of mechanical automated production needs. Strip automated production line is divided into a loading mode system, mixing a grouting system conservation systems and Chaimo system of, the location of each system in the production fixed, rely on the operating mode of the automation control system car running on a predetermined track the completion of the entire production process process, minimize manual. |
