Description

Technical Field

[0001] The utility model relates to the technical field of building structures, in particular to a frame-supported wall-beam structural system. Background Art

[0002] In the bottom frame masonry house, the conventional design of the frame-supported wall-beam structure system is to directly build the upper masonry wall and cast the structural column on the frame joist after the frame joist reaches the design strength. The upper masonry wall is connected to the frame joist only through the structural column anchored in the frame joist by the longitudinal reinforcement. As a combined load-bearing component, the wall beam is not integral enough. And under the action of horizontal earthquake, the horizontal shear bearing capacity at the interface between the wall and the beam may be insufficient. The current specification considers the partial combined action of the wall beam, and the force calculation is divided into two parts: one is that the joist bears the load alone, and the other is to consider the overall load of the wall beam and reduce this part of the load, and finally superimpose the calculation results of the two parts of the joist. Due to concerns about the difficulty in ensuring the construction quality, the insufficient connection strength of the upper wall and the frame joist joint surface, and the insufficient integrity of the wall beam, a large number of designers simply do not consider the combined action of the wall beam when designing this type of bottom frame masonry structure, and directly bear all the loads by the frame joist, resulting in excessive joist size and reinforcement, affecting the bottom net height and increasing the cost.

[0020] Embodiment 1, as Figure 1 , Figure 2 ;

[0021] The present embodiment provides a frame-supported wall-beam structural system of a bottom-frame masonry house, comprising a frame column 1, a frame joist 2, a masonry wall 6, a structural column 5, and a ring beam 7. A plurality of frame columns 1 are provided below the frame joist 2 to be connected to the house foundation, a plurality of structural columns 5 are provided above the frame joist 2 to be connected to the ring beam 7, a masonry wall 6 is built between the frame joist 2, the structural column 5, and the ring beam 7, and the masonry wall 6 is located above the frame joist 2; a plurality of protruding pin keys 3 are provided along the length direction of the frame joist 2, and the plurality of protruding pin keys 3 are embedded in the masonry wall 6, so that the wall-beam interface 4 is changed from a plane interface in the traditional design to a horse-tooth-shaped interface.

[0022] The thickness of the protruding pin key 3 is the same as the thickness of the masonry wall 6, the width of the protruding pin key 3 is 250-350mm, preferably 300mm; the height of the protruding pin key 3 is 300-400mm, preferably 350mm; the spacing of the protruding pin keys 3 is 1200-1500mm, preferably 1300mm; the protruding pin keys 3 are evenly arranged along the length direction of the frame support beam 2; the vertical cross-section of the protruding pin key 3 can be one of the shapes of rectangle, trapezoid, inverted trapezoid, etc., preferably rectangle.

[0023] More specifically, the protruding pin key 3 adopts a reinforced concrete structure, including a plurality of longitudinal bars 8, a plurality of stirrups 9 and concrete, the plurality of longitudinal bars 8 are anchored into the frame support beam 2, and the plurality of stirrups 9 connect the longitudinal bars 8 and are evenly distributed along the height direction of the protruding pin key 3.

[0024] During construction, the frame column 1 is constructed first, and then the frame joist 2 and the steel cage of the protruding pin key 3 are tied together, and the concrete of the frame joist 2 and the protruding pin key 3 are poured respectively. After the concrete strength grade of the frame joist 2 and the protruding pin key 3 meets the design requirements, the masonry wall 6 is built on the frame joist 2 according to the conventional construction method and the structural column 5 and the ring beam 7 are poured.

[0025] The number and arrangement of the stirrups 9 of the protruding pin keys 3 can be determined by calculation based on the principle that the sum of the shear bearing capacity of the protruding pin keys 3 is not less than the shear bearing capacity of the masonry wall 6 .

[0026] Through the above-mentioned processing method, that is, after a plurality of protruding pin keys 3 are set on the frame joist 2, the interface between the frame joist 2 and the masonry wall 6 becomes a horse tooth shape, which changes the form of the plane interface in the conventional design, enhances the horizontal shear and anti-slip capabilities along the axis direction of the frame joist 2 on the interface between the wall and the beam, thereby strengthening the integrity of the wall and the beam, making the wall beam as a combined component subjected to force as a whole, which can reduce the size and reinforcement of the frame joist 2, increase the net height of the bottom layer and reduce the cost.
