It is not held on shelving on beam for two neighboring steel pile casting, one end of longeron is held on positioned at Single row pillars base end part in described second
Steel pile casting is shelved on beam.
Preferably, the axis direction of longeron is located along the same line in the axis direction and second of longeron in described first.
Further, diagonal brace is fixedly connected between the other end of longeron and the surface of steel pile casting in described second.
Further, it is fixedly connected with pull rod between the end for shelving beam of the steel pile casting front and rear sides.
Further, it is fixedly connected between the support bracket and steel pile casting surface and reinforces strength plate.
The construction method of the bed die support system of the cast-in-place crossbeam of above-mentioned long piled wharf includes the following steps：
Step 1：Multiple support brackets parallel with the axis direction of single pile foundation are welded in the peripheral surface of steel pile casting；
Step 2：Axis direction of the beam perpendicular to single pile foundation will be shelved it is held on the support bracket of steel pile casting front and rear sides
On；
Step 3：The axis direction that side longeron is parallel to single pile foundation is held at left and right sides of steel pile casting and shelves beam
On.
Further, in the step 1 front and rear sides surface of steel pile casting respectively symmetrically set there are two support bracket, institute
It states to be welded between support bracket and the surface of steel pile casting and reinforces strength plate.
Further, one is respectively equipped on the support bracket of the front and rear sides of steel pile casting shelve beam in the step 2,
It shelves and is fixedly connected with pull rod between the end of beam, pull rod is parallel with the axis direction of single pile foundation.
Further, it is additionally provided with middle longeron between the side longeron in the step 3 at left and right sides of steel pile casting, in described
Longeron includes between being located at two adjacent steel pile castings, longeron and is fixed on list in parallel with the axis direction of single pile foundation first
On the steel pile casting of the rear and front end of campshed base, parallel with the axis direction of single pile foundation second in longeron；It is indulged in described first
The both ends of beam are held on the shelving on beam of two neighboring steel pile casting respectively, and one end of longeron is held on positioned at single in described second
The steel pile casting of pile foundation end is shelved on beam, is fixedly connected with diagonal brace between the other end and the surface of steel pile casting, in described first
The axis direction of longeron is located along the same line in the axis direction of longeron and second.
The beneficial effects of the invention are as follows：The across footpath of longeron is set to reduce a steel pile casting diameter by longitudinally disposed bracket
Size, the mid span moment that the cast-in-place crossbeam of longeron sufferance wharf transmits greatly reduces；In addition, side longeron is shared with middle longeron
Three, conventional method is compared, more longerons participate in stress；Middle longeron is provided at both ends with diagonal brace, and diagonal brace can effectively be held
Carry the construction load of the cast-in-place crossbeam cantilever segment of long piled wharf；Therefore the safety of bed die support system is easier to ensure that.And this reality
