Description
Technical field
The utility model relates to building and bridge field, the particularly connecting structure of a kind of steel pipe pile and reinforced concrete pile cap.
Background technology
The steel pipe pile of prior art is high owing to having supporting capacity, can adapt to the fluctuations of bearing course at pile end, spreading, prescinds conveniently, on advantages such as the impact of environment are little, becomes a kind of pile foundation form that building and bridge field often adopt.
As depicted in figs. 1 and 2, being rigidly connected of steel pipe pile 20 and cushion cap 10 is general by being imbedded by steel pipe pile 20 in cushion cap 10 after certain length, steel pipe pile outer wall 21 welds a vertical connecting reinforcement 40 of circle and stretches in cushion cap 10, in the certain length of steel pipe top, fill in reinforcing cage 30 simultaneously, in reinforcing cage 30, longitudinal reinforcement also stretches in cushion cap, with cushion cap reinforcing bar binding reinforcing cage integrally, then build wadding weft variation and the cushion cap concrete of steel pipe top, finally realize being rigidly connected of steel pipe pile 20 and cushion cap 10.
But, because steel pipe pile outer wall 21 generally needs the vertical connecting reinforcement 40 welding a greater number, be linear contact lay when adding and weld along steel pipe pile outside wall surface, therefore operate very inconvenient, and the welding job amount at scene is also larger.In addition, at steel pipe pile outer wall Site Welding reinforcing bar, length and the welding quality of vertical connecting reinforcement welding during welding are all difficult to ensure.And the welding quality of outer wall welded reinforcement realizes steel pipe pile and the rigidly connected important guarantee of cushion cap exactly.
Therefore, need to propose one and more easily ensure joint quality, facilitate the steel pipe pile of site operation and the connecting structure of reinforced concrete pile cap.
Utility model content
Because the above-mentioned defect of prior art, the utility model provides one more easily to ensure joint quality, facilitate the steel pipe pile of site operation and the connecting structure of reinforced concrete pile cap, it comprises: imbed the steel pipe pile in cushion cap and some vertical connecting reinforcements being welded in described steel pipe pile, it is characterized in that, described steel pipe pile comprises on steel pipe pile and saves stake, the welded top one that described steel pipe pile saves stake lengthens lengths of steel pipes, the end face of described lengthening lengths of steel pipes has been horizontally disposed with an annular connecting plate, interval welding (such as adopting the welding manner of arc stud welding commonly known in the art) described vertical connecting reinforcement on the plate face of described annular connecting plate.
In certain embodiments, described steel pipe pile saves stake top and embed reinforcing cage, described reinforcing cage comprises and somely stretches into longitudinal reinforcement in cushion cap and stirrup.Arrange longitudinal reinforcement in reinforcing cage and cage in the present embodiment and stirrup portion can adopt technology commonly known in the art to realize, the non-improvement place of the present utility model of this reinforcing cage part, and therefore not to repeat here.
In certain embodiments, described annular connecting plate is a horizontal annular steel plate.Certainly, replacing as one, can also be that other has certain bonding strength and is convenient to the metal sheet of welding.
On the basis meeting this area general knowledge, above-mentioned each optimum condition, can be combined, and obtains each preferred embodiment of the utility model.
The beneficial effects of the utility model: the utility model adopts and save stake top place's connection one section lengthening lengths of steel pipes on steel pipe pile, due to lengthen lengths of steel pipes can in steel work factory prior overall processing shaping, take Site Welding again, so just need not be welded to connect reinforcing bar in side one by one around the side wall surface of steel pipe column at the scene again.And only connecting reinforcement need be welded on the doughnut-shaped steel plate of level by arc stud welding, therefore welding operation is very convenient, and Site Welding workload significantly reduces than traditional sidewall weld workload.
In addition, a kind of welding procedure that electric arc stud welding of the present utility model the most often adopts when being the WELDING STUDS welding of compound beam steel work top, technical maturity, switching performance is reliable, easy construction, therefore, uses it for the connection of plain bars and steel pipe pile top steel plate in the utility model, construction is easier, and joint connects more firm.Greatly facilitate the steel pipe pile of site operation and the connection of reinforced concrete pile cap.
Be described further below with reference to the technique effect of accompanying drawing to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, characteristic sum effect fully.

Description of reference numerals: conventional art: cushion cap 10, steel pipe pile 20, steel pipe pile outer wall 21, reinforcing cage 30, vertically connecting reinforcement 40,
The utility model: cushion cap 1, steel pipe pile 2, steel pipe pile save stake 201, top 2011, reinforcing cage 3, longitudinal reinforcement 31, stirrup 32, vertical connecting reinforcement 4, lengthen lengths of steel pipes 5, horizontal annular steel plate 51
Detailed description of the invention
Enumerate preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the utility model to be described.
Embodiment
The purpose of this utility model is achieved through the following technical solutions: as shown in Fig. 3 ~ Fig. 5, the connecting structure of the steel pipe pile that the present embodiment provides and reinforced concrete pile cap comprises: imbed the steel pipe pile 2 in cushion cap 1, described steel pipe pile 2 comprises on steel pipe pile and saves stake 201, the top 2011 that steel pipe pile saves stake 201 is welded with a trifle and lengthens lengths of steel pipes 5, the end face lengthening lengths of steel pipes 5 arranges horizontal annular steel plate 51, the mode of electric arc stud welding is adopted to weld required vertical connecting reinforcement 4 at the end face of horizontal annular steel plate 51, simultaneously fill in reinforcing cage 3 saving from steel pipe pile in the certain length of stake 201 top.
Reinforcing cage 3 is provided with some longitudinal reinforcements 31 and stirrup 32, and longitudinal reinforcement 31 stretches into cushion cap 1, fixes with the reinforcing bar binding in cushion cap 1, after building steel pipe pile wadding weft variation and cushion cap concrete, then realizes being rigidly connected of steel pipe pile 2 and cushion cap 1.
The utility model one section of connecting owing to steel pipe pile saving stake 201 place lengthen lengths of steel pipes 5 can in steel work factory prior overall processing shaping, then take Site Welding, so just need not more extremely scene weld vertical connecting reinforcement 4 one by one around the side wall surface of steel pipe column.Therefore not only welding operation is convenient, and the welding job amount at scene significantly reduces than traditional on-the-spot sidewall weld workload.
In addition, a kind of welding procedure the most often adopted when electric arc stud welding of the present utility model is the WELDING STUDS welding of compound beam steel work top, technical maturity, switching performance is reliable, easy construction.
Therefore, the utility model is used for the connection of plain bars and steel pipe pile top steel plate, construction is easier, and joint connects more firm; And greatly facilitate the steel pipe pile of site operation and the connection of reinforced concrete pile cap.
More than describe each preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technician in the art according to design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
