Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
Referring to fig. 2 and 3, a bluestone railing structure of an embodiment includes a plurality of pile-foundation steel bars 1 which are reserved on the upper surface of a retaining wall and extend vertically upwards, a lower horizontal bluestone 2 which is arranged on the retaining wall, a vertical bluestone 3 and an upper horizontal bluestone 4; the lower horizontal bluestone 2, the vertical bluestone 3 and the upper horizontal bluestone 4 are sequentially arranged from bottom to top; the upper surface of the lower horizontal bluestone 2 vertically penetrates downwards to be provided with a grouting hole 201 capable of accommodating the plurality of pile foundation reinforcing steel bars 1, and the plurality of pile foundation reinforcing steel bars 1 extend upwards into the grouting hole 201; the middle part of the lower surface of the vertical bluestone 3 is prefabricated with a plurality of first reinforcing steel bars 301 which vertically extend downwards, the first reinforcing steel bars 301 extend downwards into the grouting holes 201, and concrete inner cores are poured in the grouting holes 201, so that the lower horizontal bluestone 2 and the vertical bluestone 3 are bonded into a whole.
According to the bluestone railing structure, the vertically-through grouting holes 201 are formed in the lower transverse bluestone 2, pile foundation steel bars 1 are vertically arranged in the grouting holes 201, then concrete slurry is poured in situ, and before the concrete slurry is solidified into a concrete inner core, the first steel bars 301 prefabricated on the vertical bluestone 3 vertically extend into the grouting holes 201, so that the side surfaces of two sides of the lower transverse bluestone 2 and the vertical bluestone 3 are aligned, and after the concrete slurry is solidified, the lower transverse bluestone 2 and the vertical bluestone 3 are bonded into a whole without paying attention to aligning and inserting the steel bars into the holes with the diameter being slightly larger than that of the steel bars; and will be original a whole pile foundation reinforcing bar 1 divide into two parts, partly pre-buried in putting upright bluestone 3 of one section (being first reinforcing bar 301), in another part extension inserts slip casting hole 201, is favorable to guaranteeing the tensile strength and the compressive strength of whole stand like this.
During the concrete implementation, the feasible method of prefabricating the first reinforcing steel bar 301 and the second reinforcing steel bar 303 on the vertically-arranged bluestone 3 and prefabricating the third reinforcing steel bar 401 on the horizontally-arranged bluestone 4 is to embed expansion screws on the corresponding surfaces of the bluestones, and then weld the corresponding reinforcing steel bars and the corresponding expansion screws to complete the prefabrication.
With continued reference to fig. 2, a grouting groove 302 is vertically formed downwards in the middle of the upper surface of the vertically arranged bluestone 3; a plurality of third steel bars 401 which vertically extend downwards are prefabricated in the middle of the lower surface of the upper horizontal bluestone 4, and the third steel bars 401 extend downwards into the grouting groove 302; concrete cores are poured into the grouting grooves 302, so that the upper horizontal bluestone 4 and the vertical bluestone 3 are bonded into a whole.
Thus, the upper horizontal bluestone 4 is bonded with the bonded lower horizontal bluestone 2 and vertical bluestone 3 into a whole column in the same way.
A plurality of second steel bars 303 extending vertically and upwards are prefabricated on the bottom surface of the grouting groove 302, a plurality of third steel bars 401 extend downwards into the grouting groove 302, and a concrete inner core is poured in the grouting groove 302, so that the upper horizontal bluestone 4 and the vertical bluestone 3 are bonded into a whole.
Therefore, the prefabricated second steel bar 303 is additionally arranged on the bottom surface of the grouting groove 302, and the tensile strength of the joint of the upper horizontal bluestone 4 and the vertical bluestone 3 is improved.
Wherein, pile foundation reinforcing bar 1 stretches into the degree of depth that the degree of depth of slip casting hole 201 is less than slip casting hole 201 and is greater than the half of the degree of depth of slip casting hole 201, first reinforcing bar 301 stretches into the degree of depth that the degree of depth of slip casting hole 201 is less than and is greater than the half of the degree of depth of slip casting hole 201.
