Assembly type composite wallboard and groove-shaped foundation beam self-tapping screw block connecting structure and manufacturing method

Abstract

The invention discloses an assembly type composite wallboard and groove-shaped foundation beam self-tapping screw block connecting structure and a manufacturing method, and belongs to the technical field of assembly type concrete structures. The self-tapping screw collecting block is a steel-concrete combined block which is formed after groove-shaped foundation beam channel steel with studs is connected with a composite wallboard linear force transmission steel plate through self-tapping screws, the steel-concrete combined block is 40 mm in steel structure outline, the flange of the channel steel and the force transmission steel plate have friction force generated by extrusion force between the steel plates, and meanwhile the meshing force between the steel plates and the self-tapping screws can be strengthened. Reinforcing bars of the groove-shaped foundation beam are groove-shaped reinforcement cages restrained by C-shaped stirrups; the groove-shaped foundation beam of the pre-embedded channel steel not only facilitates in-place of the composite wallboard, but also can effectively restrain bottom slippage of the composite wallboard under the action of an earthquake in the direction perpendicular to the wallboard. The assembly type composite wallboard and groove-shaped foundation beam self-tapping screw block concentrated force transfer connection structure and the composite wallboard and groove-shaped foundation beam high-performance mortar continuous force transfer connection structure have the technical advantage of cooperative and efficient stress.

Description

technical field [0001] The invention relates to a connection structure and a method for a self-tapping screw aggregate block of an assembled composite wall panel and a trough-shaped foundation beam, and belongs to the technical field of assembled concrete structures. Background technique [0002] At present, the construction technology of low-storey and ultra-low energy consumption houses in villages and towns, especially the construction technology of prefabricated ultra-low energy consumption and low-storey houses, is very lacking. The technical bottlenecks in the existing technology are: [0003] (1) The connection between the traditional shear wall and the foundation beam is a cast-in-place concrete connection, which has a large amount of wet work and a slow construction speed. There are environmental pollution problems such as large construction waste discharge and high noise during the construction process. (2) The traditional shear wall sleeve connection technology i...

Problems solved by technology

[0003] (1) The connection between the traditional shear wall and the foundation beam is a cast-in-place concrete connection, which requires a large amount of wet work and slow construction speed. During the construction process, there are environmental pollution problems such as large discharge of construction waste and high noise

(2) The traditional shear wall sleeve connection technology is not suitable for the assembly of the inner and outer leaf single-row reinforced mesh concrete thin-slab sandwich polystyrene board wall panels and the concrete foundation, because the thickness of the inner and outer leaf thin wall panels is only 40mm to 60mm (3) The traditional shear wall and foundation steel plate bolt connection technology is not suitable for the assembly of the inner and outer leaf single-row reinforced mesh concrete thin-slab sandwich polystyrene board wall panels and steel plates, because the inner and outer leaf wall boards are sandwiched between polystyrene boards In addition, thermal bridges, waterproof, moisture-proof, and corrosion-resistant steel components are considered. Polystyrene boards are not allowed to drill holes and bolts, so it is difficult to assemble the inner and outer leaf concrete thin wall panels separately by using traditional steel plate bolt connection technology; (4) The upper surface of traditional foundation beams It is flat, which is not convenient for the ecological wall panel to be in place, and is also not conducive to the lateral restraint of the foundation beam on the bottom edge of the ecological wall panel. The present invention solves this problem key technical issues
