As shown in fig. 4 to 5, based on the same concept as that of the above embodiment, in step S90, the present embodiment further proposes that the sloping beam divides the frame column into two sections, a portion of the frame column located below the sloping beam is a lower section, a portion of the frame column located above the sloping beam is an upper section, two adjacent frame columns and the sloping beam located between the two frame columns form a casting unit, any one casting unit is divided into a section a, a section B, a section C, a section D and a section E, wherein the section a and the section D are respectively a lower section and an upper section of one frame column, the section B and the section E are respectively a lower section and an upper section of another frame column, the section C is the sloping beam in the casting unit, and the casting sequence of the casting units is the section a, the section B, the section C, the section D and the section E.
In this embodiment, the frame column is divided into two sections by the oblique beam, the frame column portion located above the oblique beam is an upper section, the frame column portion located below the oblique beam is a lower section, when pouring is performed, pouring is started from the frame column with the lowest height of the lower section, the oblique beam is separated into two adjacent frame columns, and when pouring is performed on the oblique beam, a single-span pouring mode is adopted. For the pouring of the frame columns, the lower sections of the frame columns are poured firstly, the lower sections of two adjacent frame columns are poured, then the sloping beam part of the span is poured, when the sloping beam is poured, the upper section of the frame column in the span can be poured, as the adjacent span has three frame columns and the middle frame column is shared, but the pouring sequence of the frame columns and the sloping beams in the adjacent span is the same, the pouring sequence of the single span is shown as figure 5, the area A on the frame column is poured firstly, the area B on the other frame column is poured secondly, the area C on the sloping beam is poured secondly, the area E on the frame column is poured secondly, and the area F on the frame column is poured finally. For any span, two frame columns need to be sequentially poured, the frame column with the lower section of small height is poured firstly, then the frame column with the lower section of large height is poured, then an oblique beam is poured, then the frame column with the upper section of large height is poured, and finally the frame column with the upper section of small height is poured. For a single span, the pouring interval time in each span is less than the initial setting time of the concrete by 4h. When the upper section of each frame column is poured, a layered pouring mode is adopted.
As shown in fig. 6, two adjacent casting units share one frame column, and as viewed from fig. 6, the frame column is divided into a left frame column, a middle frame column and a right frame column from left to right, and the oblique beam is divided into a left oblique beam and a right oblique beam from left to right. The left frame column, the left oblique beam and the middle frame column form a first pouring unit, the first pouring unit is an A1 area, a B1 area, a C1 area, a D1 area and an E1 area, the middle frame column, the right oblique beam and the right frame column form a second pouring unit, and the second pouring unit is an A2 area, a B2 area, a C2 area, a D2 area and an E2 area; for the first pouring unit and the second pouring unit, the lower section of the middle frame column is a B1 area and an A2 area at the same time, and the upper section of the middle frame column is an E1 area and a D2 area at the same time. Therefore, the casting sequence of any two adjacent casting units is the same as that in the present embodiment.
In each span pouring sequence of the construction method, the key point is to reasonably control the time interval of layered pouring, and if the time interval is too small, the concrete in the extrusion inclined beam is turned outwards when the concrete at the upper section of the frame column is poured; if the time interval is too large, a cold joint is easily formed at the joint of the frame column and the oblique beam, which is not beneficial to the structure safety.
Tests show that the slump of the pumped concrete at the inclined beam is properly controlled to be about 160, so that the fluidity of the concrete is reduced under the condition of meeting the requirements, and the construction is convenient. The concrete at the inclined beam can be considered to be alternately poured with the concrete in the staircase.
Based on the same concept as the above embodiments, the present embodiment further provides that the spacing distance between any two adjacent frame columns is L, and L is greater than or equal to 8m and less than or equal to 10m.
In the embodiment, in order to increase the daylighting area of a breeding hall and reduce the difficulty in integrally pouring the oblique beams and the frame columns, the spacing distance between any two frame columns can be optimally selected, and the spacing distance is limited to be more than or equal to 8m and less than or equal to 10m.
The gymnasium has 5 spans on the south wall and has 6 frame columns; the west wall has 7 spans and 8 frame columns; wherein a frame column is shared at the intersection of the south wall and the west wall, and thus, 13 frame columns are connected to the oblique beams.
Based on the same concept as the above embodiments, the present embodiment further provides a U-shaped c20@100 steel bar disposed at the interface between the oblique beam and the frame column, wherein the steel bar horizontally connects the frame column and the oblique beam.
In this embodiment, for convenience of carrying out integrative the pouring with the sloping in frame post, set up the reinforcing bar of U type C20@100 in the junction of sloping and frame post to the reinforcing bar level is to connecting frame post and sloping.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present invention should be included in the protection scope of the present invention.
