Abstract
The utility model discloses a top drawknot mechanism of step infilled wall behind superelevation has solved how to improve the problem of the stability of step infilled wall body in vertical side behind the step. The concrete beam structure comprises a rear wall building body (1) and a concrete beam (2), wherein the rear wall building body (1) is arranged under the concrete beam (2), an inverted U-shaped steel clamp (5) is arranged on the lower bottom surface of the concrete beam (2), the inverted U-shaped steel clamp (5) is fixed on the lower bottom surface of the concrete beam (2) through an expansion bolt (4), and the inverted U-shaped steel clamp (5) is clamped at the top end of the rear wall building body (1); the structural safety and the shock resistance of the rear-built filling wall body are effectively improved.
Description
Technical Field
The utility model relates to a secondary structure, in particular to superelevation back step is filled secondary structure wall and primary structure at the drawknot mechanism of top position.
Background
In the construction process of public buildings, after a primary structure is constructed, the secondary structure wall is often built in the primary structure, and the building height of the post-built infilled wall is sometimes more than 6 meters; for the ultrahigh secondary structure wall, even after ring beams, constructional columns and tie bars are arranged according to the drawing specification, the stability and the structural shock resistance of the post-built infilled wall in the vertical direction are still difficult to ensure; if the number of ring beam constructional columns is additionally increased, the engineering construction cost is increased, and the problems that construction personnel are required to be increased and the potential safety hazards are more exist in field construction.
Disclosure of Invention
The utility model provides a top drawknot mechanism of step infilled wall behind superelevation has solved how to improve the technical problem of back step and has filled superelevation wall body stability in vertical side.
The utility model discloses a solve above technical problem through following technical scheme:
the utility model provides a top drawknot mechanism of filler wall builds after superelevation, builds body and concrete beam including back wall, and back wall builds the body and sets up under concrete beam, is provided with the U-shaped steel card of falling on concrete beam's lower bottom surface, and the U-shaped steel card of falling is fixed on concrete beam's lower bottom surface through expansion bolts, and the U-shaped steel card joint is on the top of the body of building wall after.
The utility model provides a top drawknot mechanism of filler wall is built after superelevation, includes that the body is built to back building wall and floor roof, and the body setting is built to back building wall under the floor roof, is provided with the U-shaped steel card of falling on the lower bottom surface of floor roof, and the U-shaped steel card of falling is fixed on the lower bottom surface of floor roof through expansion bolts, and the U-shaped steel card of falling joint is on the top of the body is built to back building wall.
The utility model discloses a back step infilled wall top and major structure's drawknot has improved back step infilled wall's structural security and shock resistance effectively, has optimized the antidetonation structure for the construction progress has saved the construction cost who additionally increases the ring beam structure post.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
the utility model provides a top drawknot mechanism of filler wall builds behind superelevation, builds body 1 and concrete beam 2 including the back of building a wall, and the body 1 sets up under concrete beam 2 is built to the back of building a wall, is provided with down U-shaped steel card 5 on concrete beam 2's lower bottom surface, and down U-shaped steel card 5 is fixed on concrete beam 2's lower bottom surface through expansion bolts 4, and the top of the body 1 is built at the back of building a wall to the 5 joints of down U-shaped steel card.
The utility model provides a top drawknot mechanism of filler wall is built after superelevation, includes that the body 1 is built to the back wall and floor roof 3, and the body 1 is built to the back wall sets up under floor roof 3, is provided with down U-shaped steel card 5 on the lower bottom surface of floor roof 3, and the steel card 5 of falling U-shaped is fixed on the lower bottom surface of floor roof 3 through expansion bolts 4, and the top of the body 1 is built to the back wall to 5 joints of the steel card of falling U-shaped.
The width of the inverted U-shaped steel clamps 5 is the same as that of the rear masonry 1, lower bent edges are arranged at two ends of each inverted U-shaped steel clamp and clamp the rear masonry 1, the distance between the inverted U-shaped steel clamps 5 is 1 meter when the seismic intensity is required to be 8 degrees, and the distance is 1.5 meters when the seismic intensity is required to be 6/7 degrees; when the width of the rear masonry body 1 is less than 200 mm, the downward length of the downward bent edge of the inverted U-shaped steel clip 5 is 250 mm, and when the width of the rear masonry body 1 is greater than or equal to 200 mm, the downward length of the downward bent edge of the inverted U-shaped steel clip 5 is 300 mm.
The utility model discloses an execute and do the step as follows:
step one, stopping building the rear wall building body 1 when the rear wall building body 1 is built to be 180 mm away from the concrete beam 2 or the floor top plate (3);
secondly, arranging inverted U-shaped steel clamps 5 on the lower bottom surface of the concrete beam 2 right above the rear wall masonry 1 or the lower bottom surface of the floor top plate 3 at intervals, and firmly fixing the inverted U-shaped steel clamps by using expansion bolts 4;
thirdly, continuing to build the rear wall building body 1, and enabling the inverted U-shaped steel clamp 5 to be clamped at the top end of the rear wall building body 1;
and fourthly, after the filling wall is built, after the rear wall building body 1 shrinks and settles for 14 days, filling a gap between the rear wall building body 1 and the top by adopting an inclined brick building method.
