Abstract
The invention discloses a connection node of a steel structure truss and prestressed concrete pipe piles. The connection node comprises a top plate and steel members, wherein the top plate is welded on the steel structure truss, the steel members are anchored to the prestressed concrete pipe piles, and the steel members are welded with the top plate. In the invention, the upper part is provided with the top plate which is welded on the steel structure truss, the lower part is provided with the steel members which are anchored to the concrete pipe pile, and the firm welded structure of the top plate and the steel members reliably connects the steel truss with the concrete pipe piles, so that the steel structure truss on the top and the prestressed concrete pipe piles as the support structure constitute an integral body to bear force together. The connection node can indirectly regulate the pile top levels of the concrete pipe piles to be consistent, thereby ensuring the required external appearance size and favorable mechanical properties of the formed structural system. The invention has the advantages of simple structure and easy manufacture.
Description
Technical field
The present invention relates to building engineering field, particularly a kind of steel structure truss and prestressed concrete pipe pile connected node.
Background technology
In engineering construction, usually can run into soft foundation pattern foundation pit supporting structure problem, and in double prestressed concrete pipe pile+waterproof of man+top steel truss supporting and protection structure the top steel truss to be connected with prestressed concrete pipe pile be difficult point, if top truss is directly welded and will certainly have many drawbacks with the pile crown flange, for example hammer piling process king-pile top mark height differs, if directly welding can be welded after will adjusting levelling with billet in advance; And because that tubular pile head flange and pile body are connected shear strength is lower, also might in being subjected to exogenic processes, cause weld seam after being welded to connect, have very big potential safety hazard by drawing crack.
Summary of the invention
The present invention provides a kind of connect steel structure truss and prestressed concrete pipe pile connected node reliable, that can adjust prestressed concrete pipe pile stake top mark high level error indirectly for solving the technical problem that exists in the known technology.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: a kind of steel structure truss and prestressed concrete pipe pile connected node, comprise with the top board of described steel structure truss welding and with steel member, described steel member and the welding of described top board of described prestressed concrete pipe pile anchor connection.
Described steel member is a H shaped steel.
Described top board is circular.
Described H shaped steel is connected with described top board full weld.
Advantage and good effect that the present invention has are: adopt top that the top board that welds with steel structure truss is set, the bottom is provided with the steel member with the concrete tubular pile anchor connection, top board reliably is connected steel truss with concrete tubular pile with the firm welded structure of steel member, makes top steel structure truss and supporting and protection structure prestressed concrete pipe pile form unified whole common load; And can adjust concrete tubular pile stake top mark height indirectly and make its horizontal absolute altitude unanimity, the apparent size requirement of structural system after guaranteeing to be shaped, good mechanical performance; Simple in structure, be easy to make.

The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1～Fig. 4, a kind of steel structure truss of the present invention and prestressed concrete pipe pile connected node, comprise with the top board 2 of steel structure truss 1 welding and with H shaped steel 3, H shaped steel 3 and top board 2 welding of prestressed concrete pipe pile 4 anchor connections.Be connected with top board 2 reliably in order to ensure H shaped steel 3, should adopt full weld to connect between the two.Being not limited to H shaped steel 3 with the steel member of prestressed concrete pipe pile 4 anchor connections, also can be i iron, also can adopt the member of steel plate welding, can also be the steel member etc. of shaped steel Combination Welding.
In order to ensure the good mechanical performance of above-mentioned connected node, top board 2 preferably adopts circular slab.
The work progress of present embodiment:
1) making of above-mentioned connected node adopts the circular steel plate of thick 20mm, diameter 600mm to be formed by connecting as the H200 * 200 shaped steel full welds of top board 2 with long 1000mm.2) installation of above-mentioned connected node is lowered to concrete pallet 6 in advance in prestressed concrete pipe pile, concrete pallet 6 is the thick steel plate of 3mm, and the reinforcing bar 7 by Φ 16mm hangs on the pile crown of prestressed concrete pipe pile 4.The H shaped steel of above-mentioned connected node is partly put into the stake core of pile tube 4, adjust circular top plate 2 end face absolute altitudes after satisfy the truss installation requirement, the tack weld support plate supports circular top plate 2 on the pile crown flange of pile tube 4; 3) above-mentioned connected node grouting anchoring, with all nodes support finish after, adopt 5 pairs of pile tubes 4 of C25 concrete anchoring H shaped steel 3 that is in the milk; 4) top truss is installed, and concrete to be in the milk reaches the installation of carrying out truss 1 after the intensity.
Although in conjunction with the accompanying drawings the preferred embodiments of the present invention are described above; but the present invention is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present invention; not breaking away under the scope situation that aim of the present invention and claim protect, can also make a lot of forms, these all belong within protection scope of the present invention.
