Description
Technical field
The present invention relates to grouting between a kind of steel core concrete column and girder steel and connect node and method of attachment, particularly relate to a kind of grouting connection node being applied in technical field of structural engineering, being particularly well-suited between the steel core concrete column of fabricated construction and girder steel.
Background technology
Concrete filled steel tube is to form a kind of combinative structure at steel duct casting concrete. Internal core concrete is subject to the effect of contraction of outside steel pipe, and its compressive property significantly improves; Outside steel pipe is subject to the lateral support of inner concrete, and local stability performance significantly improves. Compared with steel construction and reinforced concrete structure, concrete filled steel tube has that bearing capacity is high, moulding and anti-seismic performance is superior, saves the advantage such as material and easy construction, is widely used in recent years. The framework of steel core concrete column and girder steel composition is a kind of typical bearing structural system in building structure. Bean column node is to ensure that steel core concrete column and girder steel collaborative work, forms the critical component that structure is overall. Beam-ends axle power and moment of flexure are all be connected part by the edge of a wing of beam in the way of axle power to pass to post. For avoiding steel pipe partial drawn bad or reduce the effect of contraction to core concrete, generally ribbed stiffener is being set with beam tension flange corresponding position. The principal mode of ribbed stiffener has outer annular-stiffer, interior reinforcing ring, through, the four-bladed vane of ring flat-plate etc., but these ribbed stiffener processing and fabricatings are comparatively laborious and difficult, except be both needed to beyond reinforcing ring weld in steel duct. Web and the connecting plate bolt being welded on steel core concrete column side, flange of beam welds with reinforcement plate or steel pipe walls. In recent years, China promotes the assembling of housing industry, and existing scholar is proposed with the monolateral bolt of punching bolt or Introduced From Abroad and carries out the joint connection in site of steel core concrete column and girder steel. But existing test shows that the anti-bending bearing capacity adopting the bolted steel core concrete column of punching and steel beam joint is relatively big, but rotational stiffness does not meet the requirement of rigid joint. The node fabrication and installation adopting monolateral bolt are fairly simple, but because steel pipe column tube wall and flange of beam correspondence position are not provided with the measure of putting more energy into, there is local tension in vial wall, the anti-bending bearing capacity of node and rotational stiffness all do not meet the requirement of rigid joint near tension bolt.
Summary of the invention
Present invention aim at providing a kind of connection integrity good, it is prevented that the local power transmission of connecting portion steel pipe walls, connect anti-bending bearing capacity and rigidity is big, construction is simple, it is simple between site-assembled steel core concrete column and girder steel, grouting connects node and method of attachment.
In order to solve above-mentioned technical problem, a kind of technical scheme of the present invention is, between a kind of steel core concrete column and girder steel, grouting connects node, including steel core concrete column, H profile steel beam, described steel core concrete column is arranged with steel thimble, steel thimble is concentric with steel core concrete column and is positioned at outside steel core concrete column, H profile steel beam is connected with steel thimble, it is provided with high intensity grout blanket, steel thimble medial surface and steel core concrete column lateral surface between steel thimble and steel core concrete column and is provided with annular shear key.
Further, the edge of a wing of H profile steel beam and web all weld with steel thimble.
Further, annular shear key welds with steel thimble or steel core concrete column.
Further, the top of the annular shear key that the annular shear key being positioned on steel thimble is arranged on steel core concrete column, the annular shear key on steel thimble is not less than 45 degree with the line of the annular shear key on steel core concrete column with the angle of horizontal plane composition.
The method of attachment of a kind of steel core concrete column and girder steel, comprises the following steps:
(1) weld annular shear key at steel core concrete column lateral surface and steel thimble medial surface, and the angle that the line of the annular shear key on steel thimble and the annular shear key on steel core concrete column and horizontal plane are constituted after ensureing installation is not less than 45 degree;
(2) edge of a wing of H profile steel beam and web are welded with steel thimble make one;
(3) steel thimble is set on steel core concrete column;
(4) between steel thimble and steel core concrete column, build high strength grout, steel thimble is connected with steel tube concrete post.
Further, in step (1), annular shear key is round steel or steel plate is made.
Further, in step (1), the top of the annular shear key that the annular shear key being positioned on steel thimble is positioned on steel core concrete column.
Compared with prior art, the method have the advantages that easy construction is simple, it may be achieved the prefabricated construction of concrete filled steel tube; Make simple, it is not necessary to ribbed stiffener is set in steel duct or outside, hole without on steel pipe; Connecting portion is strengthened, and node globality is strong, and its load-carrying properties and rigidity are all better; Avoid because of the local tension impact on its load-carrying properties of steel core concrete column tube wall, be particularly suited for the connection of concrete-filled thin-walled steel tubular column and girder steel.
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
