Abstract

The utility model discloses an anti-pulling embedded fixed column base for a portal-rigid frame. The anti-pulling embedded fixed column base is characterized in that: a foundation short column (1) is formed by pouring concrete, wherein a local pressure resistant steel bar net piece (2) is arranged on the top of the foundation short column (1); a reverse foundation cup hole (3) is formed in the foundation short column (1); a lower section of a steel column (8) is inserted into the reverse foundation cup hole (3); a steel column bottom plate (4) is welded at the bottom of the steel column (8); steel column studs (5) are welded within a height range of the lower section of the steel column (8); a horizontal stiffening plate (6) is welded on the lower section of the steel column (8) 100mm away from the top of the foundation short column (1); and the foundation short column (1) is combined with the steel column (8) by pouring cement mortar (7) in the reverse foundation cup hole (3). By the anti-pulling embedded fixed column base, a foundation bolt is not required, the foundation short column has relatively small dimensions, the anti-pulling embedded fixed column base has a simple structure and is safe and reliable, and steel is saved.

Description

Resistance to plucking flush type portal-rigid frames rigidly connect suspension column
Technical field
The utility model relates to a kind of resistance to plucking flush type portal-rigid frames and rigidly connects suspension column.
Background technology
Portal frame structure is used for individual layer industry or civilian construction such as factory building, warehouse, station, supermarket more, its characteristics be from heavy and light, construction is simple, anti-seismic performance is good, therefore be used widely.The general employing of the suspension column of portal-rigid frames is articulated and connected, and be big when the rigid frame span, then adopt when load is big and rigidly connect suspension column, can make rigit-frame beam post reasonable stress like this, reaches the purpose of saving steel.The rigid frame of the band stiffening rib of using always at present rigidly connects suspension column and is made up of stone bolt, shearing resistance part, bottom plate of steel column foot, suspension column stiffener; This suspension column needs backup land foot bolt on basic short column; Because the suspension column moment of flexure is big; Diameter through calculating stone bolt is done also very greatly usually, and the bolt center is to the distance on the basic short column limit times diameter of bolt at least >=4, and therefore the size of basic short column is also done greatlyyer; Because the bottom plate of steel column foot bore size is limited, the embedding precision of stone bolt requires very high, if construction error is bigger, the installation meeting of portal-rigid frames is difficulty very; Because the suspension column horizontal force is bigger, independent shearing resistance part need be set resist horizontal force.The rigid frame of the band stiffening rib of therefore, using always at present rigidly connects suspension column and has the deficiencies such as difficult installation that basic short column size is big, the embedding precision of stone bolt requires height and portal-rigid frames.
Summary of the invention
The technical problem that the utility model will solve is, provides a kind of resistance to plucking flush type portal-rigid frames to rigidly connect suspension column, requires the deficiencies such as difficult installation of height and portal-rigid frames to overcome the basic short column size embedding precision big, stone bolt that prior art exists.
Resistance to plucking flush type portal-rigid frames rigidly connect suspension column and take following technical scheme: basic short column is made of the perfusion concrete; Anti-office wherein is set at basic short column top presses reinforced mesh; Reverse cup hole, basis is set in basic short column; The hypomere of steel column is inserted in the reverse cup hole, basis; The weldable steel column base plate in the bottom of steel column; Welding steel column peg in the hypomere altitude range of steel column is apart from downward 100mm place, basic short column top, at the hypomere weld horizontal stiffener of steel column; The basis short column combines with steel column by cement injection mortar in reverse cup hole, basis.
Resistance to plucking flush type portal-rigid frames rigidly connect the job practices of suspension column and take following technical scheme: it comprises following process: one, and the concrete pouring construction of basic short column is provided with anti-office at basic short column top and presses reinforced mesh, stays in basic short column inside and establishes reverse cup hole, basis; Two, make steel column, weldable steel column base plate in the bottom of steel column; Welding steel column peg in the hypomere altitude range of steel column; At the hypomere weld horizontal stiffener of steel column, the welding position of horizontal stiffener is reference with basic short column top, at distance downward 100mm place, basic short column top; Three, treat after basic short column concrete strength meets the demands steel column to be installed, the steel column hypomere is inserted in the reverse glass hole, basis; Four, perfusion secondary cement mortar in reverse cup hole, basis, cement mortar fills up reverse cup hole, basis, and steel column combines with basic short column.
Can find out from above technical scheme; Through perfusion secondary cement mortar in reverse cup hole, basis; By reverse cup hole, basis and the cement mortar that wherein solidifies etc., then form a reverse taper, after cement mortar reaches intensity; Basis short column and reverse taper co-operation wherein form integral body, and basic short column forms the effect of hoop.Anti-office presses the existence of reinforced mesh, can guarantee at steel column foot stressedly when very big, is not crushed by the part in the top of basic short column.The existence of steel column base plate can guarantee to convert the frictional force between steel column and the concrete into pressure.The existence of steel column peg can guarantee that basic short column, reverse taper and steel column have firm combination, and can share the part shearing between steel column and the concrete.The existence of horizontal stiffener can help steel column opposing horizontal shear.Realized rigidly connecting of portal-rigid frames suspension columns through said structure.
The structure of the utility model need not be provided with stone bolt, and basic short column size is less relatively, simple installation between suspension column and the basis, and construction is simple, does not need to be provided with separately the shearing resistance part.On the whole resistance to plucking flush type suspension column simple structure, save steel, safe and reliable, for large span, have factory building than gross ton position crane to use greater advantage is arranged.
