The node includes the angle steel lattice column of the vertical supporting member constructed before the implementation of the top-down method and the first floor beam constructed in the implementation of the top-down method. The top of the angle steel lattice column is positioned at the bottom of the first floor beam. The node is characterized in that the connection of the first floor beam and the angle steel lattice column is provided with a column terminal, the column terminal is positioned at the right lower end of the juncture of the first floor beam and the angle steel lattice column, the size of the cross section is always consistent with that of the cross section of a permanent frame column, a plurality of bidirectional horizontally distributed ribs are arranged inside, a column is connected with the beam through the vertical reinforcement ribs in the column terminal, the column is provided with two rows of angle steel up and down in the scope of the column terminal, and the bottom of the column terminal is wrapped with channel steel. The beam column node provided in the utility model completely solves the crossing problem of the steel bar of the first floor beam, and the disadvantages of the present node are overcome.
Description
Affiliated technical field
The utility model relates to the structure connected node in a kind of base pit engineering contrary sequence method, especially a kind of doubling as the structure first floor beam of horizontal supporting system and the angle steel lattice column connecting T-shaped node of vertical support member.
Background technology
Contrary do the stage and often need to column be set as vertical support in frame column position, until contrary do to finish after again in steel post outside in addition concreting form permanent frame column.And there is column against doing stage frame column position, thus the problem of bringing bean column node middle frame beam steel to pass through, this problem is also the contrary general character difficult problem in technique of doing.
In general contrary working method engineering, comparatively common column is angle steel lattice column, and at present, the beam-column connection in contrary sequence method mainly contains boring reinforcing bar connection method, power transmission steel plate method, beam side haunch method for angle steel lattice column.But all there is corresponding deficiency in above the whole bag of tricks: boring reinforcing bar connection method has cross section damage to vertical support steel post, power transmission steel plate method can reduce the bearing capacity of steel work and increase the difficulty that concrete compaction is built, and beam side haunch method increases the difficulty of site operation.
Summary of the invention
The utility model provides a kind of contrary sequence method beam column connecting T-shaped node, and this node can solve the problem that first floor structural beams reinforcing bar passes through completely, and makes up the deficiency of existing connected node.
The utility model is achieved by the following technical solution:
For a beam column connecting T-shaped node for base pit engineering of topdown construction method, comprise main muscle in angle steel lattice column, first floor structural beams, styletable head, channel-section steel, angle steel, vertical strengthening ribs, horizontal distribution muscle, beam.It is characterized in that: by styletable head, connect first floor structural beams and angle steel lattice column, angle steel lattice column top absolute altitude equals the end absolute altitude of first floor structural beams, and rear monobloc cast concrete has been welded in the colligations such as reinforcing bar, form the T-shaped node of beam column.
Based on above-mentioned technical characterictic, the vertical strengthening ribs in styletable head is connected column with structural beams, is conducive to improve the horizontal shearing resistance of beam column; Configuring multi-layer two-way horizontal distribution bar in styletable head, and at upper and lower side welding angle steel, be conducive to improve vertical shear-carrying capacity and the globality of beam column.
Based on above-mentioned technical characterictic, styletable head bottom welding channel-section steel, is connected by peg between channel-section steel and lattice column, and described peg is arranged along the outer perimeter spaced surface of described angle steel lattice column.Being provided with of channel-section steel is beneficial to and strengthens anchor ear effect.
In said method first floor structural beams, acerous steel lattice column penetrates, successfully solve the reinforcing bar of underground first floor bean column node in contrary working method engineering and passed through a difficult problem, by the application of the measures such as vertical strengthening ribs, channel-section steel and angle steel, the problems such as its shear-carrying capacity is low have well been solved simultaneously.
