A kind of support construction of foundation pit, if including arterial highway supporting beam and support column, if arterial highway supporting beam intersects at a bit, institute The lower section that support column is vertically set on supporting beam crosspoint is stated, the support column includes several support units, described in several Support unit headtotail forms support column, passes through connection frame connection between the adjacent support unit.
It, all can be in support column in order to increase the support strength of support column when worker constructs by using above-mentioned technical proposal Interior casting concrete, when in foundation pit construction complete need to remove when, can only be removed by way of cut support column support column with Concrete therein removes concatenation unit, then dismantling concrete when needing to remove support column by the way that concatenation unit is arranged , support column can recycle, and reduce construction cost.
Further, the support unit includes four L-shaped supporting blocks, and four supporting blocks are separately fixed at company It connects in frame, two sides of the supporting block are tightly attached to the inner sidewall of connection frame respectively.
It by using above-mentioned technical proposal, connects frame and plays the role of connecting two sections of supporting blocks, and connect frame and also act as The effect of reinforcing increases the structural strength of support column entirety.
Further, the connection bolt for connecting adjacent supports block, the connection bolt are provided in the connection frame Across supporting block and connection frame, one end of the connection bolt is arranged with fixture nut.
It by using above-mentioned technical proposal, connects bolt and passes through supporting block and connection frame, then connection bolt is secured with nuts, Achieve the purpose that support frame and connection frame fitting are fixed, and connect bolt-through connection frame, further functions as increase support The purpose of the support strength of column.
Further, locking nut is arranged on the connection bolt, the locking nut setting is close in fixture nut Connect the side of frame.
By using above-mentioned technical proposal, locking nut and fixture nut are mutually limited, by the self-locking feature of screw thread, Gu Determining nut will not loosen, correspondingly, connection bolt will not loosen.
Further, the both ends of the support column are provided with attachment base, and the attachment base is embedded in inside supporting beam, institute Support column is stated to be removably mounted on attachment base.
By using above-mentioned technical proposal, attachment base is embedded in inside supporting beam, and bolt is integrated with supporting beam, then is led to It crosses support column to fix with bolt, support column achievees the effect that support supporting beam, and facilitates the dismounting of support column.
Further, the side of the connection frame at the support column both ends turns down outward forms flange, and the flange passes through spiral shell Bolt is fixed on attachment base.
It is all by support column with cutting machine from branch since worker is when removing support column by using above-mentioned technical proposal It is cut down on support beam, causes support column that cannot recycle, increase construction cost, fixed by using bolt by frame is connected Mode on attachment base facilitates the dismounting of support column, support column is enable to recycle, reduce and apply after construction is completed Work cost.
Further, the lateral surface of the connection frame is wholely set the ribs of the structural strength for increasing support column Plate, the deep floor are fixed on flange far from a side of connection frame.
By using above-mentioned technical proposal, deep floor is set in the lateral surface of connection frame, the support for increasing support column is strong Degree, enables support column to play good supporting role.
Further, the concrete for increasing support column overall structural strength is poured inside the support column.
By using above-mentioned technical proposal, after the hollow internal casting concrete of support column, concrete formation with support Column surrounds one, and overall structural strength increases.
Compared with prior art, the utility model has the beneficial effects that
(1) by setting supporting block and connection frame, support column using complete remove when, successively by supporting block from connection frame Interior dismounting, and the concatenation unit removed can be recycled, and construction cost is reduced;
(2) pass through setting connection bolt, connection bolt-through connects frame, plays and is fixedly connected with supporting block and connects frame Effect, and connect bolt and play the support strength for increasing support column;
(3) by setting attachment base, support column is bolted on attachment base, by support column between supporting beam When removing, cutting support column is not needed, improve support column recycles rate, reduces construction cost.
