Abstract
The invention discloses a bottom die supporting system of a long-piled wharf cast-in-place beam and a construction method of the bottom die supporting system. The bottom die supporting system comprises a plurality of steel protection cylinders arranged on the surface of a pouring pile in the axis direction of a single-row pile foundation. A plurality of supporting brackets parallel to the axis direction of the single-row pile foundation are fixed to the surfaces of the steel protection cylinders in the circumferential direction. Shelving beams perpendicular to the axis direction of the single-row pile foundation are shelved on the supporting brackets located on the front sides and the rear sides of the steel protection cylinders. Side longitudinal beams which are shelved on the shelving beams and are parallel to the axis direction of the single-row pile foundation are arranged on the left sides and the right sides of the steel protection cylinders. The span length of the longitudinal beams is reduced by the diameter of one steel protection cylinder through the longitudinally-arranged brackets, and the mid-span moment, borne by the longitudinal beams, transmitted by the cast-in-place beam is greatly reduced; and the number of the side longitudinal beams and the number of middle longitudinal beams are each three. Compared with a traditional method, one longitudinal beam is additionally arranged to participate in stress; inclined struts are arranged at the two ends of each middle longitudinal beam and can effectively bear the construction load of a cantilever section of the long-piled wharf cast-in-place beam; and thus, the safety of the bottom die supporting system is more easily guaranteed.
Description
Technical field
The present invention relates to long piled wharf construction of beam technical field, in particular to bed die support system and the construction method thereof of the cast-in-place crossbeam of a kind of long piled wharf.
Background technology
The crossbeam of long piled wharf is positioned at pile foundation top, the pile foundation of single framed bent connects into entirety, and the upper load of long piled wharf is passed to pile foundation.At present, the pile foundation of long piled wharf is frequently with the bored concrete pile of band steel pile casting, after filling pile construction completes, bored concrete pile need to be relied on to set up the bed die support system of crossbeam cast-in-place construction.Tradition sets up the way of bed die support system: installing steel hoop on bored concrete pile, the bracket setting direction of steel hoop is perpendicular to the axis direction of single framed bent pile foundation, is laterally；Then on bracket, lay longeron, distribution beam, form bed die support system.When the pile foundation spacing that single framed bent is adjacent is bigger, the mid span moment of longeron can be very big, to such an extent as to the risk that collapses occurs in bed die support system.
Summary of the invention
Present invention aim to solve the deficiency of above-mentioned background technology, it is provided that the bed die support system of the cast-in-place crossbeam of a kind of long piled wharf and construction method thereof, the support strength of this system is higher, and longeron moment of flexure is little, it is ensured that the Stability Analysis of Structures of bed die casting system.
For realizing this purpose, the bed die support system of the cast-in-place crossbeam of long piled wharf designed by the present invention, the many steel pile casting on bored concrete pile surface it are arranged at including the axis direction along single pile foundation, the peripheral surface of described steel pile casting is fixed with the support bracket that the axis direction of multiple and single pile foundation is parallel, being positioned at supporting of both sides before and after steel pile casting and be shelved with the shelve beam vertical with the axis direction of single pile foundation respectively on bracket, being respectively arranged on the left side and the right side to be held on of described steel pile casting is shelved on beam and the limit longeron parallel with the axis direction of single pile foundation.
Further, be additionally provided with middle longeron between the limit longeron of the described steel pile casting left and right sides, described middle longeron include between two adjacent steel casings longeron in parallel with the axis direction of single pile foundation first and be fixed on single pile foundation before and after two ends steel pile casting on longeron in parallel with the axis direction of single pile foundation second；What in described first, the two ends of longeron were held on adjacent two steel pile casting respectively shelves on beam, and in described second, one end of longeron is held on the shelving on beam of steel pile casting being positioned at Single row pillars base end part.
Preferably, in the axis direction and second of longeron, the axis direction of longeron is located along the same line in described first.
Further, it is fixedly connected with diagonal brace between the other end and the surface of steel pile casting of longeron in described second.
Further, it is fixedly connected with pull bar between the end shelving beam of both sides before and after described steel pile casting.
Further, it is fixedly connected with between described support bracket and steel pile casting surface and adds powerful plate.
The construction method of the bed die support system of the cast-in-place crossbeam of above-mentioned long piled wharf comprises the following steps:
Step one: the peripheral surface at steel pile casting welds the support bracket that multiple and single pile foundation axis direction is parallel；
Step 2: the axis direction shelving beam and being perpendicular to single pile foundation is held on before and after steel pile casting on the support bracket of both sides；
Step 3: limit longeron is parallel to the axis direction of single pile foundation and is held on the shelving on beam of the steel pile casting left and right sides.
Further, in described step one, before and after steel pile casting, both side surface is respectively symmetrically and is provided with two support brackets, is welded with and adds powerful plate between described support bracket and the surface of steel pile casting.
Further, being respectively equipped with one and shelve beam in described step 2 before and after steel pile casting on the support bracket of both sides, shelve and be fixedly connected with pull bar between the end of beam, pull bar is parallel with the axis direction of single pile foundation.
Further, described step 3 is additionally provided with between the limit longeron of the steel pile casting left and right sides middle longeron, described middle longeron include between two adjacent steel casings longeron in parallel with the axis direction of single pile foundation first and be fixed on single pile foundation before and after two ends steel pile casting on longeron in parallel with the axis direction of single pile foundation second；What in described first, the two ends of longeron were held on adjacent two steel pile casting respectively shelves on beam, in described second one end of longeron be held on be positioned at Single row pillars base end part steel pile casting shelve on beam, being fixedly connected with diagonal brace between the other end and the surface of steel pile casting, in described first, in the axis direction and second of longeron, the axis direction of longeron is located along the same line.
The invention has the beneficial effects as follows: made the size reducing a steel pile casting diameter across footpath of longeron by longitudinally disposed bracket, the mid span moment that the cast-in-place crossbeam of longeron sufferance wharf transmits is greatly reduced；It addition, limit longeron and middle longeron have three, comparing traditional method, many longerons participate in stress；The two ends of middle longeron are provided with diagonal brace, and diagonal brace can carry the construction load of long piled wharf cast-in-place crossbeam cantilever segment effectively；Therefore the safety of bed die support system is easier to ensure that.And present configuration is simple and convenient to operate, there is bigger promotional value.
