Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The first embodiment is as follows:
the utility model provides a combined bearing rear anchor bolt embedded part as shown in figures 1-3, which comprises a first embedded part 5 and a second embedded part 6 which are fixedly arranged on adjacent roof girders 2 through connecting parts 1, wherein the connecting parts 1 are rear anchor bolts or full-thread screws. Waist holes 3 are formed in the first embedded parts 5 along the arrangement direction of the second embedded parts 6, the other sides of the first embedded parts 5 are fixedly connected with steel columns 7, and the first embedded parts 5 and the second embedded parts 6 are welded and fixed by abutting against one ends;
when a steel structure factory building is newly built on a roof, pre-embedded parts are required to be pre-installed in order to fix steel columns 7, the first pre-embedded parts 5 are fixedly installed on steel beams through rear anchor bolts or full-thread screws penetrating through waist holes 3 formed in the first pre-embedded parts 5, and the second pre-embedded parts 6 are fixedly connected with another roof beam 2 through the following two installation modes;
one is that when adjacent roof girders 2 are relatively perpendicular, the second embedded parts 6 are in a long strip shape, and the other is that when adjacent roof girders 2 are relatively parallel, the second embedded parts 6 are in a T shape, and the transverse parts of the T-shaped second embedded parts 6 are fixedly arranged along the roof girders 2.
After the installation is finished, only the vertical force transmitted by the columns and the horizontal force vertical to the roof truss are born through the first embedded parts 5; and because waist hole 3 has been seted up along second built-in fitting 6 arrangement direction on the first built-in fitting 5, reserve out certain space for second built-in fitting 6 bears the horizontal force along the roof truss direction that the post transmitted, through the cooperation of the two, strengthens whole built-in fitting and receives the comprehensive bearing capacity of cutting, pulling, and the bearing effect is better, and life is longer, and is stronger to the suitability when the margin is less.
