Concrete structure and construction method of frame structure infill wall and window sill

Abstract

The invention discloses a frame structure filled wall window sill roofing concrete masonry structure, which comprises a window sill roofing prefabricated block and a window sill roofing template; the window sill roofing prefabricated block is a cuboid made of concrete, the middle of which is pre-embedded and protruded, and the window sill roofing prefabricated block There is a reserved hole in the middle; the window sill top formwork is a long strip frame welded with square tubes, the middle of the frame is welded with steel plates, and holes are reserved on the steel plates at both ends of the frame; two window sill top prefabricated blocks are built on both sides of the window sill, two The pre-embedded and protruding steel bars on the window sill top prefabricated block are bound and overlapped with each other, and the lap length is 36*the diameter of the steel bar; the window sill top formwork is closely attached to the inside and outside sides of the window sill top top prefabricated block from the inner and outer sides of the wall. The pull bolts pass through the reserved holes of the window sill top prefabricated blocks to connect the window sill top formwork and fix them with nuts. The invention adopts the window sill capping concrete masonry structure combined with prefabricated blocks and formwork pouring, which is fast and convenient in construction, firm in structure and not easy to leak.

Description

technical field [0001] The invention relates to a concrete construction method for filling a window sill of a frame structure. Background technique [0002] With the acceleration of urbanization in my country, the lack of land resources is prominent, and the cost of land per square meter of construction area remains high. Therefore, restrictions on the design and construction of multi-storey brick-concrete structures have been introduced in various places, which are gradually replaced by small high-rise and high-rise buildings. The building structure has also changed from a single brick-concrete structure to a framed concrete filled wall structure and a framed shear wall structure. [0003] The frame concrete infill wall structure better solves the land resources, and the infill wall is replaced by lightweight materials or hollow wall blocks. However, poor structural integrity and leakage water concentration points will be formed at the window sill, and subsequent design and ...

Problems solved by technology

[0004] The conventional method of cast-in-place window sill topping is: when filling the wall to the window sill position, pour reinforced concrete window sill topping first, and continue to lay bricks after the reinforced concrete topping is poured, and masonry workers need to stop and wait for this part, resulting in intermittent time for wall masonry Long, affecting the construction period is not conducive to improving production efficiency, and the upper wall after the topping concrete is poured will also lead to the defect of poor connection integrity under the wall; on the other hand, the installation of cast-in-place formwork and the supply and pouring of concrete are difficult

[0005] Therefore, some construction units have adopted prefabricated window sill roofing. First, the prefabricated window sill roofing is limited by the length of the window sill. The finished product is not suitable for protection, and the construction operation is cumbersome. Second, when the connecting mortar is not full, there will be hidden dangers of leakage.
