Projected area, and in the orthographic projection of the first steel plate.
Steel plate is rectangle steel plate, the full weld welding of H profile steel floor and steel plate.H profile steel floor uses Q235-B steel, model
Hhx300x11x18.H profile steel floor is 8mm with the steel plate throat thickness.Steel plate uses Q235-B steel, and the thickness of steel plate is
The surface of 20mm, steel plate are equipped with rib, and the thickness of rib is 5mm.H profile steel floor is arranged along the length direction of the steel plate;Position
It is respectively placed on the step in outermost two H profile steel floors;H profile steel floor along the steel plate long side direction every
1.0m settings are together.
A kind of holes blocking structure of the present invention, including holes blocking precast construction;Further include side wall, the hole of hole
Hole side structure reinforcing bars, waterproof polymer mortar layer, steel armpit angle.
Side wall is two stage steps side wall, and described hole is divided into narrower bore position and wide aperture position;The hole side at the top of wide aperture position
Surrounding structure reinforcing bars part is exposed, which extends from hole edge toward side structure direction.
Holes blocking precast construction is arranged in wide aperture position;First edges of plate is placed in the side structure of hole, and first
Fluting is respectively set in edges of plate;In the exposed described hole side surrounding structure reinforcing bars merging fluting of wide aperture and with institute
State the welding of the first steel plate.Weld length is the length of 20 times of hole side structure reinforcing bars diameters.Exposed hole positioned at wide aperture position
22 times of the diameter of structure reinforcing bars when the length of structure reinforcing bars is hole.The length for the part of first steel plate being placed in the structure of side
Degree is 0.1 times of the hole length of side, and the part is not less than the length of the hole side structure reinforcing bars diameter described in 22 times.Second steel plate
It is supported on the step structure of two stage steps side wall, step width is more than 300mm, the highly thickness for 1/3 hole.
Steel armpit angle is set to narrower bore position and is adjacent to side wall setting, the wing at steel armpit angle while be located at narrower bore hole while tie
Structure reinforcement welding (being welded with the exposed end of hole side structure reinforcing bars herein), another wing side and the surface of the second steel plate are welded
It connects.Steel armpit angle uses Q235-B steel, and thick 20mm, right angled triangle, short right-angle side is 1 with long right-angle side ratio:2.Steel armpit angle is along institute
The short side distribution of steel plate is stated, and together every 0.5m settings.
Waterproof polymer mortar layer is set to the lateral surface of the first steel plate and extends in the side structure of hole, and covers exposed
Hole side surrounding structure reinforcing bars.Waterproof polymer mortar thick layer exceed original structure face 10mm, be layed in steel plate just on
Side, the length of side of waterproof polymer mortar layer exceed the length of side 100mm of the first steel plate respectively.Holes blocking structure of the present invention
Construction:Reserving hole surrounding is dug into stepped first, step width 300mm~400mm is highly 1/3 hole thickness.Root
Select precast construction after steel plate, H profile steel floor and steel plate full weld to weld according to step-like hole size, along steel plate long side direction every
