Description
Technical field
The utility model is related to a kind of mechanical equipments to overhaul mounting technique, more particularly, to a kind of connection on concrete column
Device.
Background technology
Heavy mechanical equipment is being installed or overhauled, can all be related to the connection of steel construction and concrete column, i.e. steel construction and coagulation
The connection of earth pillar.Due on concrete column can not welding steel, when steel construction is needed to be connected with concrete column, run on concrete column
There is no a built-in fitting or built-in fitting position offset causes concrete column majority can use expansion bolt to fix steel when cannot be with steel structure connection
Plate realizes the connection of steel construction and concrete column, but this connection structure causes steel plate that cannot bear larger load, easily causes and sets
Standby is unbalance.
Utility model content
The purpose of this utility model is just to provide a kind of attachment device on concrete column, existing for connecting to solve
The smaller problem of bearing load present in the attachment device of concrete column and steel construction.
The object of the present invention is achieved like this：
A kind of attachment device on concrete column, including the banding body that is used to be set on the outside of concrete column and for by banding body
Several expansion bolts being fixedly connected on concrete column, the banding body include four banding pieces, and four banding pieces surround structure
Into the rectangular cylinder of both ends open, the banding piece is bonded setting with the side of concrete column respective side, the every banding piece with
It is fixedly connected by welding between adjacent banding piece；
It is provided with to accommodate the bolt penetration hole that the expansion bolt passes through in the every banding on piece, is arranged on every
The bolt penetration hole of the banding on piece is arranged in multiple lines and multiple rows.
The every banding piece uses steel plate.
The diameter of the bolt penetration hole is more than the diameter of the expansion bolt.
The utility model includes being set in the banding body on the outside of concrete column with being arranged on for banding body to be fixedly connected
Several expansion bolts on concrete column, the banding body include four banding pieces, and four banding pieces surround composition both ends and open
The rectangular cylinder put, side of the banding piece with concrete column respective side are bonded setting, since banding piece is bonded with concrete column side
It sets so that banding piece is tightly combined with concrete column.And pass through the side of welding between the every banding piece and adjacent banding piece
Formula is fixedly connected, and can so enable the attachment device producing balanced forces, other banding pieces of the device can pair and steel structure connection
Banding piece generate the pulling force of a balance, therefore the attachment device can bear larger load.
The utility model have it is at low cost, time saving and energy saving it is efficient, small, light-weight, adaptable and fabrication cycle is short
Etc. advantages, the utility model is smaller to the destructive power of concrete column in addition, have higher promotional value.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the top view of the utility model.
In figure：1st, banding piece；2nd, expansion bolt；3rd, concrete column.
Specific embodiment
As depicted in figs. 1 and 2, the utility model includes for the banding body that is set on the outside of concrete column and for by banding body
Several expansion bolts 2 being fixedly connected on concrete column, banding body include four banding pieces 1, and every banding piece 1 uses steel plate system
Into.In the present embodiment, every banding piece 1 is rectangular steel plates.Four banding pieces 1 surround the rectangular cylinder for forming both ends open
Body, banding piece 1 are bonded setting with the side of 3 respective side of concrete column, pass through welding between every banding piece 1 and adjacent banding piece
Mode be fixedly connected, in the present embodiment, the water of the length of the horizontal direction of every banding piece 1 and the corresponding side surface of concrete column 3
Square to equal length.The angle welding for welding is provided between every banding piece 1 and adjacent banding piece.
It is provided with to accommodate the bolt penetration hole that expansion bolt 2 passes through on every banding piece 1, is arranged on every banding piece
On bolt penetration hole be arranged in multiple lines and multiple rows, the diameter of bolt penetration hole is more than the diameter of expansion bolt 2.
The installation method of the utility model is：Banding piece 1 is processed for four sides of concrete column 3 and concrete column 3 is right
Answering the side of side can fit closely, and the side of banding piece 1 and 3 respective side of concrete column, which can fit closely, can increase between the two
Frictional force；Multiple lines and multiple rows bolt penetration hole is opened up in every banding piece 1, the diameter of each bolt penetration hole is all higher than expansion bolt 2
Diameter；Expansion bolt through the bolt penetration hole of banding piece 1 and is driven on concrete column 3, four banding pieces 1 are each attached to concrete
Expansion bolt is fastened to predetermined pretightning force after on column, expansion bolt 2 is fastened to after predetermined pretightning force to two neighboring banding
Angle welding between piece 1 is welded.The connection construction of steel construction can be carried out after welding, if expansion bolt 2 and steel
It, can be with the position of local directed complete set expansion bolt 2 when structure connection position is equipped with conflict.
The manufacturing process of the utility model is simply easily implemented, and need to only be operated according to the technological requirement of the utility model,
Special training need not be carried out, general technical staff can grasp the technology, and carry out practical operation.Therefore this practicality
New technical data and operating procedure great popularization.
