Description
Technical Field
The invention belongs to the technical field of building structures, and particularly relates to a construction method of a hidden type stone-built wall body with an embedded assembly type H-shaped steel framework.
Background
The masonry structure is used as a traditional and old building structure form, and is still largely used by village and town residents at present due to the fact that local materials are easily obtained, transportation is convenient, construction is simple and the like. Masonry structures mainly include common sintered brick masonry structures, masonry structures and block masonry structures of other materials. The sintered brick is mainly made of clay, shale and the like by firing, natural rubble blocks or boulders are the main raw materials of the masonry structure, and other block masonry structures can be made of industrial waste materials (slag and the like). Obviously, the masonry structure has a wide material source for a long time and is easy to use locally; meanwhile, the brick, stone or block masonry has good durability, fire resistance and chemical stability, and also has good heat insulation performance; secondly, compared with the reinforced concrete structure, the masonry does not need a template and special mechanical equipment during the building, the template can be saved, the construction period is shortened, and the manufacturing cost is low. Therefore, the masonry structure wall is a good bearing structure and a good enclosure structure, and still occupies an important position in civil building construction of vast rural areas, villages and towns, and even county cities at present. Particularly, a large number of Tibetan rubble masonry structure houses still exist in western Sichuan plateaus and Qinghai-Tibet plateaus, and the Tibetan rubble masonry structure houses are wide in application and long-lasting in history on the Qinghai-Tibet plateaus due to the advantages that the Qinghai-Tibet plateaus are rich in stones, local materials are easy to obtain, severe cold climate in plateau regions is resisted, and the like. The bearing wall body of the Tibetan stone-built building is formed by dry-building of rubble and clay, a plurality of gravel pieces are mixed in the middle of the bearing wall body, yellow mud caulking is adopted, the strength is low, the thickness difference of the caulking is large, and the ring beam and the constructional column adopted by the masonry structure design specification (GB50003-2011) are not adopted for integral reinforcement during building. Meanwhile, the floor system of the Tibetan stone-built building is formed by ramming wood, clay and the like, the integrity of the building is poor, and the stone wall body cannot be effectively horizontally supported during earthquake, so that the out-of-plane damage of the wall body can occur. Although under the action of small earthquake and short-period earthquake, the hidden stone wall dissipates earthquake energy due to the closing and the pulling of the gaps among the blocks, and has certain energy dissipation and shock absorption functions; however, under the action of strong earthquake and long-period earthquake, the hidden stone wall has poor integrity and is easy to damage outside the plane of the wall, so that the wall collapses, and personnel and property loss is caused. Civil buildings collapse in earthquakes occurring in recent years, and the main reason is that the building with the masonry structure is lack of members for restraining excessive deformation of the wall, and the failure of a single wall easily causes the overall collapse. In particular, the Tibetan masonry walls in earthquakes are subject to failure, partial collapse and general collapse due to lack of effective restraint. In recent years, the earthquake resistance of the hidden stone-built building is gradually concerned, and through investigation and structural analysis on earthquake damage of the hidden stone-built building after an earthquake, the improvement of the earthquake resistance of the hidden stone-built building is found to mainly solve the earthquake resistance of the hidden rubble wall, limit overlarge out-of-plane space displacement of rubble blocks of the wall in the earthquake, restrain the generation of out-of-plane dislocation among the rubble blocks, improve the shearing resistance of the rubble wall and the overall stability of a house, and further improve the earthquake resistance of the hidden stone-built building. Meanwhile, the green building and the building industrialization greatly promote the reform of urban building industry, aim at the requirement of novel urbanization construction, and greatly improve or develop a batch of novel construction technologies with land conservation, water conservation, energy conservation, material conservation and environmental protection on the premise of keeping the regional characteristics and national characteristics of the civil building, so that the technical system and product equipment of the civil building in key links of green energy conservation, environmental quality improvement, engineering construction efficiency, quality safety and the like reach the international advanced level; finally, the quality, the energy efficiency and the construction efficiency of civil buildings in various regions are improved, so that large-scale, high-benefit and sustainable development are realized. Meanwhile, the maintenance, the reinforcement, the transformation and other work are carried out on the traditional Tibetan type stone-made house, and the safety and the comfort level of the traditional Tibetan type stone-made building are improved on the premise that the national features and the high-altitude area features of the traditional Tibetan type stone-made building are kept. Therefore, the earthquake-resistant improvement technology and the earthquake-resistant design theory research are developed on the Tibetan plateau rubble masonry structure, the novel earthquake-resistant design technology or theory which is more economical and applicable is provided, and the requirement of novel highland urbanization construction can be well met.
Obviously, the adoption of the ring beam constructional column is the most effective earthquake fortification measure for improving the earthquake resistance of the stone building structure; however, the cast-in-place ring beam constructional column is not beneficial to storing national characteristics and regional features of the Tibetan stone-built building, and meanwhile, the cast-in-place ring beam constructional column can cause serious damage to the ecological environment of a plateau area due to the procedures of on-site formwork erecting, pouring, maintenance and the like. Meanwhile, in view of the overall anti-seismic performance of civil buildings in the Tibetan region, the existing house building process is simple, the farmer and herd living houses in most regions are designed and built according to local house building customs, building materials are made according to local conditions and local materials, raw soil, stone materials and wood materials are used mostly, and the anti-seismic performance is relatively weak. Therefore, on the premise of considering the national characteristics and regional features of the Tibetan region building, the steel structure assembly type building technology is utilized to develop the local industrialized earthquake-resistant technical research aiming at the Tibetan region rubble masonry house, the novel Tibetan rubble wall body building technology is formed, the important significance and the good application prospect are achieved, and the novel Tibetan region rubble wall body building method has great economic value and social benefit for building, reinforcing and maintaining the Tibetan region rubble masonry structure house.
The H-shaped steel is selected to carry out the improvement on the earthquake-resistant construction technology of the Tibetan rubble wall body, because the section shape of the H-shaped steel is similar to that of an H-shaped economic section profile, which is also called universal steel beam, wide-edge (side) I-shaped steel or parallel-flange I-shaped steel and the like, the H-shaped steel can be suitable for different steel structures, and H-shaped steel members show excellent performance no matter bear bending moment, or bear loads such as tension, compression or shearing force. Compared with the common I-shaped steel, the H-shaped steel greatly improves the bearing capacity and saves the steel consumption by 10 to 40 percent. The steel consumption can be saved by 15-20% when the H-shaped steel is used for building the steel truss. Meanwhile, the planes of the inner side and the outer side of the flange of the H-shaped steel are parallel, and the end part of the flange and the joint of the flange and the web are right-angled, so that the H-shaped steel is convenient to assemble and combine into steel members in various shapes, the assembly type construction is convenient, and the construction period is obviously shortened. Therefore, the H-shaped steel combination is selected and applied to the hidden rubble wall to form the assembled integral steel skeleton, and in the rubble wall building, the application of the H-shaped steel avoids the complex procedures of binding a reinforcement cage, manufacturing a template, pouring vibrating concrete and the like in a construction site. The method not only realizes convenient and quick production, transportation and construction and short construction period, but also meets the development strategy requirement of 'novel urban and rural construction in plateau' provided by a Tibetan region for keeping the national characteristics and the landscape of the traditional Tibetan stone-built building, and accords with the sustainable development strategy of green buildings.
