Description
Technical field
The present invention relates to building engineering field, in particular to a kind of constructional column close U-shaped concrete segment and its
Construction method.
Background technique
Setting constructional column is needed in the masonry filler wall of reinforced concrete structure, is wanted to meet its stability and anti-seismic construction
It asks.Constructional column is commonly referred to as concrete-constituted pile, is the predetermined portion in masonry house wall, by constructional reinforcement, and by first building
Concrete column made of the sequence of construction of placing concrete column, constructional column are generally arranged at the half space of staircase after wall,
Longitudinal cross wall junction, the corner of wall, long more than the 2 times layers height of wall or the intermediate position greater than 5 meters.
In the prior art, it pours component and needs first to carry out formwork, however formwork complex steps, Quality Control Links are more,
And needing to put into more manpower, and more using consumptive material, such as plate, screw rod through walls etc., construction cost investment is larger；
In the construction process, plate is connected with wall is not easy to appear spillage phenomenon tightly, and the use of screw rod through walls causes to construct
There is perforation in column, the quality of constructional column is impacted.
In view of this, the present invention is specifically proposed.
Summary of the invention
The first object of the present invention is to provide a kind of constructional column and closes U-shaped concrete segment, the U-shaped concrete block
Block can be avoided the formwork in constructional column casting process, improve speed of application and construction quality, and can be avoided and pouring
The destruction of the U-shaped concrete segment is caused under the pressure of concrete and when vibrating after building concrete and is fallen off.
The second object of the present invention, which is to provide, a kind of replaces constructional column tradition formwork using above-mentioned U-shaped concrete segment
Construction method, this method can ensure that constructional column and U-shaped concrete segment are effectively be bonded, and can be improved the appearance of constructional column
Quality and integral construction progress.
In order to realize above-mentioned purpose of the invention, spy uses following technical scheme：
The first aspect of the present invention is to provide a kind of constructional column and closes U-shaped concrete segment, the U-shaped concrete block

12 parts.
By the way that the U-shaped concrete segment to be used to pour in constructional column in the present invention, it can be avoided and poured in constructional column
Formwork in the process improves speed of application and construction quality；In the present invention, by using specific concrete prefabricated U-shaped
Concrete segment can be improved speed of application and ensure the intensity of U-shaped concrete segment, can be avoided in casting concrete
The destruction of the U-shaped concrete segment is caused under the pressure of concrete and when vibrating afterwards and is fallen off.
Further, the U-shaped concrete segment is formed by the raw material including following parts by weight is prefabricated：15 parts of cement, machine
41 parts of sand processed, 43 parts of rubble and 9 parts of water；
Preferably, the ballast grain sizes are 5-20；Machine-made Sand partial size is 0.5-0.25mm；
Preferably, the U-shaped coagulation block thickness is 18-24mm.
By the specific selection of the specific dosage of above-mentioned concrete material and rubble and Machine-made Sand partial size, can be improved described
The compression strength of U-shaped concrete segment；In addition, can be avoided and pouring by the restriction to the U-shaped concrete segment thickness
The destruction of the U-shaped concrete segment is caused after concrete under the pressure of concrete and when vibrating and is fallen off；In the present invention
If the thickness of U-shaped concrete segment described in is too thin to be easily caused broken in the construction process, directly results in construction once broken
Column can not pour, and it is time-consuming to take material；And thickness is too thick, can be influenced by constructional column reinforcing bar, and block construction can not be organized, and cuts if changing pillar muscle
Face then will affect constructional column intensity.
Further, steel fabric sheet is provided in the U-shaped concrete segment；Preferably zinc-coated wire mesh sheet；More preferably
Ground, steel wire diameter is 0.8-1mm in the steel fabric sheet；Grid is 10mm × (8-12) mm.
By the setting of above-mentioned steel fabric sheet, the integral strength of U-shaped building block can be improved.
The intensity of U-shaped concrete segment is not limited strictly in the present invention, the preferably described U-shaped concrete segment is anti-
Compressive Strength >=20MPa.
By the restriction of above-mentioned compression strength, and it can be avoided and pouring with U-shaped concrete segment thickness collective effect
The destruction of the U-shaped concrete segment is caused after concrete under the pressure of concrete and when vibrating and is fallen off.
The size of U-shaped concrete segment is not limited strictly in the present invention, it is preferable that the U-shaped concrete segment
Including a variety of different sizes；Specifically, the bottom edge length in the U-shaped concrete segment section is 240mm, 360mm and 200mm
In any one, any one in side edge length 95mm, 115mm, 230mm and 290mm.
By above-mentioned various sizes of setting, can satisfy different construction demands, and be applicable in the middle part of wall and
In the pouring of end different location constructional column, have a wide range of application.
The second aspect of the present invention provides a kind of construction method that constructional column is poured using above-mentioned U-shaped concrete segment, packet
Include following steps：
(1) according to architectural design drawing, the thickness of filling wall, and prefabricated U-shaped concrete segment are determined；

(3) when building height to 1.2-1.8m, pouring for constructional column is carried out；
(4) continue to build, when masonry to wall collar tie beam, constructional column pours simultaneously with collar tie beam；
(5) continue to build, until filling walling and U-shaped concrete block masonry are completed, then, complete pouring for constructional column
It builds.
It can guarantee that constructional column and U-shaped concrete segment are effectively be bonded by above-mentioned construction method, and can be improved structure
Make the presentation quality and integral construction progress of column.
Further, the U-shaped concrete segment is identical as the material of constructional column.
By the way that the U-shaped concrete segment and constructional column are selected identical material, can further improve described U-shaped
The adhesive strength of concrete segment and constructional column；Further, since the U-shaped concrete segment and constructional column concrete strength one
It causes, can guarantee that constructional column quality is unaffected.
The masonry way of U-shaped concrete segment is not limited strictly in the present invention, it is preferable that when constructional column setting exists
When filling the middle part of wall, the U-shaped concrete segment open end is opposite to be built, and the neighbouring U-shaped concrete segment
Bottom edge length it is different；
