Abstract
The invention discloses a prefabricated concrete column in butting connection by steel nodes. The prefabricated concrete column comprises a prefabricated concrete column body, a first steel node positioned at one end of the prefabricated concrete column body, and a second steel node positioned at the other end of the prefabricated concrete column body, wherein the first and second steel nodes are matched. As the first steel node and the second steel node are additionally arranged at the two ends of the prefabricated concrete column body, two sections of prefabricated concrete columns can be quickly matched and connected by using a principle of mutual matching of the first and second steel nodes; and then, the matched place is fixed through electric welding, so that the butting connection between the two sections of prefabricated concrete columns can be guaranteed, the traditional scene butting wet operation of prefabricated concrete columns is prevented, and the construction efficiency is quickened. The prefabricated concrete column is simple in structure and low in cost; and after the steel nodes are used for connecting, the node stress and the node ductility are improved.
Description
Technical field
The present invention relates to construction engineering technical field, particularly a kind of steel node that adopts docks the precast concrete column connected.
Background technology
Precast concrete has the advantage of standardized designs, prefabricated production, prefabricated construction, is a kind of structural shape meeting the industrialization of construction industry mode of production, is more and more widely used at present.
In the precast concrete system that current application is general, often need more piece concrete column to dock connection successively, realize precast concrete system.Wherein, docking between upper and lower joint precast concrete column is connected with two kinds of modes, a kind of mode is by rigging at the scene, then carry out concrete building to realize connecting, another kind of mode is: adopt slurry anchor to connect and save precast concrete column up and down, above-mentioned two kinds of forms of construction work all cannot avoid situ wet operation, also reduce the efficiency of construction of precast concrete.In addition, precast concrete column also has and adopts cylinder prefabrication, the on-the-spot way adopting the docking of prestressing force dry method, but presstressed reinforcing steel wear that to draw also be a procedure of more complicated.
Summary of the invention
The invention provides a kind of steel node that adopts and dock the precast concrete column connected, two joint precast concrete column can be connected fast, situ wet joint can be avoided to connect simultaneously, improve efficiency of construction.
For solving the problems of the technologies described above, the invention provides a kind of precast concrete column, comprise: precast concrete column body, be positioned at the first steel node of described precast concrete column body one end and be positioned at the second steel node of the described precast concrete column body other end, first, second steel node described agrees with.By setting up the first steel node and the second steel node at precast concrete column body two ends, utilize the principle that first, second firm contact agrees with mutually, can fast two joint precast concrete column be connected together, again this is agreed with to place and carries out electric welding and fix, just the stable connection between two joint precast concrete column can be guaranteed, avoid situ wet operation, accelerate efficiency of construction.The structure of this precast concrete column is simple, with low cost.
As preferably, described first steel node comprises: the first steel fastener and be arranged on the positioning and guiding steel plate of described first steel fastener surrounding, and one end of described first steel fastener is anchored in described precast concrete column body.Together with this first steel fastener can be cast in precast concrete column body in advance when factory carries out precast concrete column, easy to process, described positioning and guiding steel plate can position the second steel node and lead, and realizes the quick connection between two joint precast concrete column.
As preferably, described second steel node comprises the second steel fastener matched with described first steel fastener and positioning and guiding steel plate, and one end of described second steel fastener is anchored in described precast concrete column body.That is, together with described second steel fastener can be cast in precast concrete column body when factory carries out precast concrete column equally in advance.
