The invention relates to the technical field of building
engineering design and construction crossing, in particular to a design and construction method of temporary gate-type channel for building. The design and construction method of the temporary gate-type channel for the building comprises the following steps that 1, the position and composition of a temporary door type channel are determined; 2, a plane position map of the vertical rods of the beam and slab formwork
supporting system is drawn; 3, plane positions of I-shaped steel stand columns, I-shaped steel main beams and I-shaped steel secondary beams are determined; 4, the
axial force of a vertical rod above the temporary gate-type channel is calculated; 5, the
bearing capacity of the I-shaped steel secondary beams is calculated; 6, the
bearing capacity of the I-shaped steel beams is calculated; 7, the
bearing capacity of the I-shaped steel stand columns is calculated; 8, I-shaped steel stand column construction is calculated; 9, the I-shaped steel stand columns is connected to the I-shaped steel main beams; 10, the I-shaped steel secondary beams are connected to the I-shaped steel main beams; and 11, a formwork
supporting system is erected. The design and construction method is good in stress performance, safe and convenient to construct, short in period and low in cost, solves the key technical problem of design and construction of the temporary door type channel for the building, meets the efficient and energy-saving green construction requirements, and has great application and popularization value.
