the utility model provides a bent cap construction bracket device, includes pier stud, bearing girder, distribution secondary beam and bent cap, the bearing girder sets up in the top of pier stud, the distribution secondary beam sets up in the top of bearing girder, the bent cap sets up in the top of distribution secondary beam, the bottom of bearing girder and the both sides that are located the pier stud all are equipped with a sand section of thick bamboo, the fixed sand section of thick bamboo backing plate that is equipped with between the top of a sand section of thick bamboo and the bearing girder, the fixed rod backing plate that is equipped with in bottom of a sand section of thick bamboo, the inside of pier stud is passed and is equipped with the rod, the bottom of rod backing plate is seted up and is used for the semicircular hole that the rod passed, the opposite tie rod preformed hole has all been seted up to the both sides of rod backing plate and the lateral wall of pier stud, and the inside of opposite tie rod preformed hole is passed and is equipped with the opposite tie rod and through nut fixed connection.

Preferably, the two sides of the bent cap are construction platforms, and guard rails are fixedly arranged on the two sides of the top of the bent cap.

Preferably, the steel bar backing plate is a Q235 steel plate with the thickness of 2 cm.

Preferably, the two tie rod preformed holes are symmetrically positioned on two sides of the semicircular hole.

Preferably, the diameter of the sand cylinder is 350mm.

Preferably, the diameter of the steel bar is 140mm, and the diameter of the counter pull rod is 25mm.

Compared with the prior art, the utility model provides a bent cap construction bracket device possesses following beneficial effect:

this bent cap construction bracket device through passing the setting on the rod iron backing plate and to the pull rod, can repeatedly have enough to meet the need the use, can effectively reduce the tradition simultaneously and can cause to have certain corner between sand section of thick bamboo and the rod iron through fixed one pad flat steel sheet on the cross core rod iron for the normal use security of entire structure improves.

The part that does not relate to among the device all is the same with prior art or can adopt prior art to realize, the utility model discloses can be after the back field preparation, the assembly of front field, overall structure installation is simple, and installs the easy control of quality.
