Abstract
The invention relates to the field of civil building construction operation, in particular to the field of operation of a connecting joint between concrete columns. A prefabricated concrete column connecting joint structure is characterized by comprising an upper section of connecting column and a lower section of connecting column connected through screw bolts, wherein each connecting column comprises a pair of flat plates in horizontal arrangement and a group of reinforcing ribs connected with the two flat plates. With the design, parts of the structure can be prefabricated in capable factories and then conveyed to a construction operation site for connection and concrete casting, so that the operation is convenient, and the quality is also guaranteed.
Description
Technical field
The present invention relates to Civil Engineering Construction operation field, especially design the connected node operation field between concrete column and post.
Background technology
At present concrete column is connected pattern and mainly contains sleeve and connect with slurry anchor and be connected with node between post: sleeve connection cost is too high, and grouting quality is subject to execute-in-place ambient influnence, and whether slip casting is full cannot check one by one; The quality major part of slurry anchor node depends on the operant level of field worker, and quality of connection cannot be verified one by one.
Summary of the invention
The object of the present invention is to provide the prefabricated units connected node that a kind of cost is low, performance is ripe, easy to control the quality.
In order to achieve the above object, the present invention is achieved in that
A precast concrete column connecting joint structure, it comprises with bolted upper and lower two sections of joint pins, described joint pin comprises the dull and stereotyped of a pair of horizontal arrangement and connects two one group of dull and stereotyped stiffening ribs.
Described precast concrete column connecting joint structure, all has through hole on upper joint pin, lower joint pin, and lower joint pin end face is provided with shear key.
Described precast concrete column connecting joint structure, stiffening rib is provided with stirrup.
The preparation method of described precast concrete column connecting joint structure, it comprises
Step 1, upper and lower two sections of joint pins are adopted respectively to steel welding production;
Step 2, transport upper and lower two sections of joint pins to operation field;
Step 3, by the upper and lower firm bolt of bolt for two sections of joint pins;
Step 4, the complete joint pin of bolt be placed in to construction put 1 ~ 1.3 meter of on flooring, in joint pin periphery, stirrup is set,
Step 5, joint pin is implemented formwork and pouring concrete operation and it is connected with target cylinder;
Step 6, after concrete is solid, implement formwork and remove operation.The present invention adopts above-mentioned design, and it can transport to and to construction operation scene, connect and fluid concrete after tool factory with good conditionsi makes in advance, and so, easy to operate, quality is also secure.
Accompanying drawing explanation
Fig. 1 is upper joint pin structural representation.
Fig. 2 is lower joint pin structural representation.
Fig. 3 is upper and lower joint pin syndeton schematic diagram.
The specific embodiment
By specific embodiment, further illustrate the present invention below.
As shown in Figure 1, Figure 2 and Figure 3, a kind of precast concrete column connecting joint structure, it comprises the upper and lower two sections of joint pins 1,11 that connect with bolt 13, and described joint pin 1,11 comprises the flat board 2,3,7,8 of a pair of horizontal arrangement and connects two dull and stereotyped one group of stiffening ribs 5,6.
Described precast concrete column connecting joint structure, all has through hole on upper joint pin 1, lower joint pin 11, and lower joint pin 11 end faces are provided with shear key 9.
Described precast concrete column connecting joint structure, stiffening rib 5,6 is provided with stirrup 12.
The preparation method of described precast concrete column connecting joint structure, it comprises
Step 1, upper and lower two sections of joint pins are adopted respectively to steel welding production;
Step 2, transport upper and lower two sections of joint pins to operation field;
Step 3, by the upper and lower firm bolt of bolt for two sections of joint pins;
Step 4, the complete joint pin of bolt be placed in to construction put 1 ~ 1.3 meter of on flooring, in joint pin periphery, stirrup is set,
Step 5, joint pin is implemented formwork and pouring concrete operation and it is connected with target cylinder;
Step 6, after concrete is solid, implement formwork and remove operation.
The present invention adopts above-mentioned design, and its advantage is:
This connected node is different from traditional bean column node, avoids the area of stress concentration of beam column, is chosen in 1 ~ 1.3m punishment on flooring and separates.
This connected node chief component is comprised of two parts: factory-made component and building site cast-in-situ concrete; So, easy to make, precision is high, quality is guaranteed; Meanwhile because this node used be general steel plate and bolt, therefore sleeve node relatively, this node cost significantly reduces.
