Description
Technical field
The present invention relates to house construction engineering field, it is related to a kind of room and builds assembled technology more particularly to a kind of precast hollow wall
Column and its construction method.
Background technique
During building house or mansion, it is necessary to first build and build foundation, then on this basis with reinforcing bar and mixed mud
The construction of main body is carried out, including wall column and crossbeam etc., traditional construction method are after arranging reinforcing steel bar shelf, to be wrapped up with template,
Then then placing concrete, compacting, coagulation forming are successively increased.The shortcoming of this construction method is exactly construction efficiency
Not high, template loss is excessive, and environmental pollution is serious, and is easy waste concrete in the construction process.
Existing prefabricated construction system be using prefabricated solid component as main member, it is cast-in-place through assembly, connection, part
Made of concrete structure.It is solid wall column that the shortcomings that this construction method, which is prefabricated wall column all, is the connection of upper and lower wall column
Difficulty is brought with part cast-in-place construction, and the quality after pile is difficult to control.
Summary of the invention
The purpose of the present invention is low for assembled wall column construction efficiency and excessive, existing prefabricated wall column pile is lost in template
Quality is difficult to control and the problems such as connecting portion constructional difficulties, and it is simple to provide a kind of construction technology, at low cost, high-efficient, ecological
Precast hollow wall column and its construction method.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is that:
A kind of precast hollow wall column, it is characterised in that: be made of the splicing of more piece open tubular column, the open tubular column, which is equipped with, runs through two
The internal cavities at end, open tubular column one end are equipped with female, and the other end is equipped with male connector, passes through male connector and female between adjacent open tubular column
Splicing forms complete concrete wall column, male connector and female composition connection in internal cavities placing concrete after the completion of splicing
Part.
As an improvement, the open tubular column lower end of bottommost is flush end or is connected with ground by connector, the sky of top
Stem top is flush end or is connected with crossbeam by connector.
As an improvement, the end of the open tubular column is that three steps are stepped, wherein the middle part of highest step is equipped with protrusion, most
The matched groove of protrusion on size and adjacent vacant stem is equipped in the middle part of low step, the ladder at open tubular column both ends is contrary, so that
Open tubular column one end is male connector, and the other end is female.
As an improvement, the ladder table top at the male connector end is equipped with several connection sleeves or connection reinforcing bar, the female
The ladder table top at end is equipped with the corresponding connection reinforcing bar of quantity and position or connection sleeve.
As an improvement, the connection sleeve is higher than ladder table top, and when so that adjacent vacant stem docking, the ladder table top of male connector
There is gap between the ladder table top of female, when adjacent vacant stem internal cavities are poured concrete, concrete is by the rank of male connector
Gap between halfpace face and the ladder table top of female is filled up.
As an improvement, open tubular column end face cavity mouth surrounding each ladder table top up to less be equipped with a connection reinforcing bar or
Person connects sleeve.
As an improvement, the connection reinforcing bar is equipped with unidirectional groove, the connection sleeve is equipped with unidirectional tooth, so that connection
Reinforcing bar can be inserted into the one-way movement of connection sleeve, and the connection sleeve is expansion sleeve, and connection sleeve, which is equipped with, pricks muscle, work as connection
When reinforcing bar and connection sleeve fix, tightened by pricking muscle.
As an improvement, the ladder table top of the hollow column end is intilted inclined-plane, so that ladder table top is generally
Wedge shape.
As an improvement, the open tubular column upper side is equipped with the preformed hole for installing crossbeam.
A kind of precast hollow wall column construction method, which comprises the following steps:
Step 1, precast hollow column, be prefabricated in the factory open tubular column, according to hollow column dimension assembling reinforcement, then inside and outside installation
Template is fixed between inner and outer template with pull rod, the male connector and female of open tubular column both ends three steps step type is reserved according to shape, is poured
Prefabricated open tubular column is obtained after note maintenance molding；
Prefabricated open tubular column, is stitched together by step 2, open tubular column splicing installation as needed, the public affairs of adjacent vacant stem
Head and female, in the ladder table top preset clearance of adjacent hollow column end, are transferred to being correspondingly connected in the internal cavities of open tubular column
The steel reinforcement cage bound；
Step 3, installation crossbeam, bind crossbeam reinforcing bar, supporting beam template on corresponding open tubular column on preformed hole；
Step 4, casting, according to being first poured crossbeam lower part, being poured crossbeam again, the sequential casting for being finally poured crossbeam top is empty
The internal cavities of stem after maintenance molding, complete the construction of precast hollow wall.
The medicine have the advantages that
The present invention uses structure for the male connector of mirror type and female connection type, so that the duplicate mould of each open tubular column
Block, male connector and female use staged, and Tai Ji door tilts, and form wedge shape, so that open tubular column Aligning degree is significantly when installation
It improves, can be effectively prevented because contraposition caused by open tubular column self weight process is difficult to install, while presetting and running through in open tubular column
The inner wall cavity at both ends, after open tubular column is installed as needed, the casting concrete in internal cavities completes last system
To make, such beam column had not only had the cast-in-place intensity of tradition but also had had the convenient degree of assembled beam-column installation and meet construction period,
The advantages of being provided simultaneously with cast-in-place beam column and fabricated construction, relative to conventional wall column construction method, it is of the invention it is easy to operate, apply
Work simple process and low cost, high-efficient, ecological, environmental protective.
