Examples are given. A double-spliced rectangular core-penetrating rod device is shown in figures 1-6 and comprises a group of pier studs 5, a group of rectangular core-penetrating rods 1, a section steel cross beam 2, a pull rod 3 and a wood wedge block 4; run through on the pier stud 5 and be provided with two pier stud preformed holes, install a rectangle piercing rod 1 in two pier stud preformed holes separately, the cross section of rectangle piercing rod 1 is the rectangle, and the mounting means of rectangle piercing rod 1 is the long limit of rectangle in the vertical direction.
This device sets up two rectangles and pierces through stick 1, rather than with single stick of wearing, because "single stick of wearing" can only realize through increaseing cross-sectional dimension when needs improve the bearing capacity, and the expansion of pre-buried hole will inevitably disturb the vertical main muscle of pier stud, can influence the anti-seismic performance of pier stud. This device "two core bars of wearing" pre-buried two less hole installation rod steels of thickness respectively, when guaranteeing the bearing capacity, can not cause the interference to the vertical main muscle of pier stud.
The section steel cross beams 2 on two sides of the pier stud 5 are connected in a counter-pulling mode through pull rods 3.
The aspect ratio of the cross section of the rectangular core-through rod 1 is not more than 3, and the purpose is to prevent the rectangular core-through rod 1 from generating torsional deformation instability due to the overlarge aspect ratio.
And wood wedge blocks 4 are clamped in the gaps between the two ends of the two rectangular core penetrating rods 1. The wood wedge block 4 is clamped between the two rectangular core penetrating rods 1, and mainly prevents one independent steel rod from shaking, so that the other steel rod is stressed too much, the integral stability of the structure is influenced, and the wood wedge block is an auxiliary construction measure for improving the stability.
The wood wedge block 4 is bound on the rectangular core penetrating rod 1 through an adhesive tape.
The rectangular core penetrating rod 1 is of a solid structure. The solid structure has higher bearing capacity under the same external dimension, and is more convenient to customize and process; the high-strength steel can provide higher bearing capacity, the general range of the bracket is improved, and the material strength is at least Q345 steel.
The size of each side of the pier stud preformed hole is 0.8-1.2cm larger than that of each side of the rectangular core penetrating rod 1.
The size of each side of the pier stud preformed hole is 1cm larger than that of each side of the rectangular core rod 1. A certain size is reserved, so that the installation of the rectangular piercing rod 1 is facilitated.
The section steel cross 2 is selected according to the structural bearing.
The application method of the double-spliced rectangular core penetrating rod device comprises the following steps:
(1) When installing the bracket, when installing earlier, install two rectangle piercing pins 1 in pier stud rectangle preformed hole, each side size of preformed hole is 1cm than each side size of rectangle piercing pin 1, and the long limit of piercing pin cross-section is in the vertical direction, and the cross-section minor face is in the horizontal direction. The gap between the ends of the two rectangular piercing rods 1 is clamped by a wood wedge block 4 and then is bound on the rectangular piercing rods 1 by adhesive tapes. The section steel beam 2 clings to the pier column and is arranged on the rectangular penetrating rod 1, and the section steel beams 2 on two sides of the pier column are connected in a counter-pulling mode by using the pull rod 3
(2) After bearing, the section steel beam 2 transmits load to the rectangular core penetrating rod 1, the rectangular core penetrating rod 1 serves as a main bearing component, the pull rod 3 is worn with a nut and serves as an auxiliary component for preventing the section steel beam 2 from moving and overturning, and the pull rod 3 can be tightly attached to the section steel beam 2 after the nut is screwed without being tightened;
(3) When the bracket is dismantled, the bracket is unloaded firstly, the pull rod 3 is taken down, the section steel beam 2 is lifted away, the wood wedge block 4 and the rectangular penetrating rod 1 are dismantled, the preformed hole of the pier stud is repaired, and the construction is completed.
The above description is only for the preferred embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can substitute or change the technical solution of the present application and its concept within the technical scope of the present application, and shall be covered by the scope of the present application.
