Problems solved by technology
[0003] (1) The connection between the traditional cast-in-place 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 prefabricated shear wall and foundation sleeve connection steel bar technology is expensive and not suitable for the connection of prefabricated ecological interior walls and foundation beams
(3) The upper surface of the traditional foundation beam is flat, which is not convenient for the placement of the ecological wall panel, and it is also not conducive to the lateral restraint of the foundation beam on the bottom edge of the ecological wall panel
(4) The price of self-tapping screws is relatively low, which is very suitable for the assembly of reinforced concrete frame ecological wall panels and foundation beams, but there is no matching connection structure before

Embodiment Construction
[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of this application.
[0031] like Figure 1-6 As shown, the self-tapping screw block is a one-shaped steel plate with self-tapping screw holes and an anchor bolt at the lower part with self-tapping screw holes welded on the steel bars of the trough-shaped foundation beam reinforcement cage, which is also used as a force transmission steel plate and a connecting steel plate. The C-shaped connecting steel plates welded on the steel bars of the concrete bottom frame are connected by s...

The invention discloses an assembly type ecological inner wall and groove-shaped foundation beam self-tapping screw block connecting structure and a construction method, and belongs to the technical field of assembly type concrete structures. The self-tapping screw block is a steel-concrete combined block which is formed by connecting a groove-shaped foundation beam with a stud connecting steel plate and an ecological wallboard C-shaped force transmission steel plate through self-tapping screws and has a steel structure contour of 40mm; 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 groove-shaped reinforcing bar type facilitates in-place of the ecological wallboards and can effectively restrain the ecological wallboards from bottom slippage under the action of an earthquake in the direction perpendicular to the wallboards. The ecological inner wall is composed of a concrete frame and a light ecological environment-friendly plate filled in the concrete frame, and the light ecological environment-friendly plate is prepared from solid waste such as fly ash and slag; the ecological wallboard and trough type foundation beam self-tapping screw block concentrated force transfer connection structure and the ecological wallboard and trough type 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 an assembled ecological inner wall and a trough-shaped foundation beam self-tapping screw block connection structure and method, 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 existing in the prior art are: [0003] (1) The connection between the traditional cast-in-place shear wall and the foundation beam is the connection of cast-in-place concrete, 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 prefabricated shear wall and foundation sleev...
