Description

Square steel pipe sand pebble ring beam-construction column construction suitable for masonry structure houses in villages and towns technology

technical field

The invention belongs to the technical field of building structures, and specifically relates to a combination of sand pebbles and square steel pipes, which is suitable for the construction technology of square steel pipe sand pebble ring beams and structural columns for masonry houses in villages and towns. The basic requirements for the construction of "farm houses".

Background technique

Masonry structures mainly include ordinary clay brick structures, stone structures and block structures of other materials. Clay bricks are mainly fired with clay, natural stone is the main raw material of stone structure, and blocks can be made of industrial waste (slag, etc.). Obviously, masonry structure materials have a wide range of sources and are easy to obtain locally; at the same time, brick, stone or block masonry has good durability, fire resistance and chemical stability, and also has significant thermal insulation properties; secondly, masonry There is no need for formwork and special construction equipment during masonry, which can save wood, and save a lot of cement and steel compared with reinforced concrete structures. Therefore, the masonry structure wall is not only a good load-bearing structure but also a good enclosure structure, and it still occupies an important position in the construction of civil buildings in vast rural areas, towns, and even counties in my country. In the late 1980s and early 1990s, masonry structures accounted for more than 90% of the total number of buildings in villages and towns, and basically did not test the requirements for seismic fortification; The villagers began to pay a certain degree of attention to the anti-seismic fortification measures, and some newly built masonry structures also designed and added reinforced concrete ring beams, structural columns and other anti-seismic fortification measures. However, due to the weak bond between bricks, stones, blocks and mortar, the tensile, flexural and shear strength of unreinforced masonry is very low; and the basic materials and connection methods of blocks and mortar determine In view of its brittle nature, if the ring beam structural column is not designed and constructed according to the requirements of the code, or only part of the wall is set, or the design and construction of the section size, reinforcement, and tie reinforcement are not standardized, it will not achieve a good seismic fortification effect. As a result, the seismic effect of masonry structures is still poor. According to statistics, the severe damage and collapse of masonry structures in the Tangshan earthquake accounted for more than 90%; the Wenchuan earthquake caused more than 6.5 million houses to collapse and more than 23 million houses to be damaged, of which 3.476 million rural houses were damaged in Sichuan. Farm houses in villages and towns in Beichuan, Wenchuan, Yingxiu and other districts and counties in the epicenter were particularly severely damaged. Therefore, it is necessary to pay enough attention to the seismic fortification of civil buildings in villages and towns. The Wenchuan and Lushan earthquakes also show that improving the seismic performance of masonry structures in villages and towns is an urgent problem to be solved.

Domestic and foreign research and engineering practice have shown that setting ring-beam structural columns is the most effective measure to improve the seismic performance of masonry structures. The reason is that the hoop effect of the closed ring beam construction column can effectively restrain the deformation of the wall and enhance the integrity and stability of the masonry structure. On the one hand, the ring beam can not only reduce the adverse effects on the building due to uneven foundation settlement or large vibration loads and cause wall cracks, but also the ring beam can cooperate with the floor slab and structural columns to enhance the overall rigidity and stability of the building , reduce the damage to the house caused by the uneven settlement of the foundation, and resist the impact of earthquake force. On the other hand, the structural columns and ring beams work together to divide and surround the brick masonry to form a whole. When the masonry cracks, it can force the cracks within the enclosed range and prevent further expansion. Even if the masonry has cracks under the action of the earthquake, the ring beam structural column can effectively limit its dislocation, so that it can maintain its bearing capacity and offset the vibration energy so that it is not easy to collapse early. Through engineering practice, it has been found that the masonry structure houses with low storeys and uniform structural layout have good seismic performance after setting up structural columns and ring beams, and can achieve the fortification target of 8 degrees; the houses after the Wenchuan and Lushan earthquakes The results of the earthquake damage investigation also show that the masonry structure buildings with structural columns and ring beams set up in accordance with the code requirements can be "cracked and not collapsed" during the earthquake. Although most villagers in post-disaster reconstruction and current new rural construction have realized the importance of ring-beam structural columns in the seismic fortification of masonry structures, due to limited traffic conditions, high construction costs, long construction periods, and complicated construction techniques, etc., Some villagers are unwilling to set up ring-beam structural columns, or only some walls are equipped with ring-beam structural columns. At the same time, due to the lack of formal design and the lack of guidance and supervision of skilled technical personnel in villages and towns, even if ring beam structural columns are installed, there is no guarantee that their quality can meet the requirements for seismic fortification.

However, the square steel pipe sand pebble component is a composite member formed by filling the square steel pipe with unbonded sand pebbles according to a certain degree of compaction. The composite member makes full use of the retarding effect of the sand and pebbles on the local buckling of the steel pipe during the stress process, making it under a complex stress state, and the strength and stability can also be greatly improved, so as to ensure that the mechanical properties of the material can be fully exerted. Compared with concrete-filled steel pipe columns, sand and pebbles can compensate for the stress concentration caused by uneven shrinkage and deformation of concrete. In addition, it can also abandon the long construction period, high cost, and poor reproducibility of steel pipe concrete after reaching the service life, resulting in new buildings. Disadvantages such as garbage and not conducive to energy saving and environmental protection reuse. Filling sand and pebbles into square steel pipes to replace traditional reinforced concrete ring beam construction columns is not only easy to obtain local materials and convenient and fast construction, but also has a short construction period, and has excellent characteristics such as energy saving, land saving, material saving, and environmental protection, which conforms to the national standard.
