Abstract
The tower crane cruciform steel structure foundation changes the traditional reinforced concrete tower crane foundation into the cruciform steel structure foundation, which adopts I-shaped profiled bar or II-shaped profiled bar, which is connected into the cruciform steel girder through welding or with high-strength bolt, thereby replacing the traditional reinforced concrete foundation. The utility model is suitable for various tower crane foundations and has the advantages of short construction period, low cost, repetitive use and environmental protection.
Description
Technical field
The utility model relates to a kind of pillar crane cross steel work basis.
Background technology
Traditional tower crane foundation adopts the cast-in-situ steel reinforced concrete basis, and concrete and reinforcing bar content are bigger.Usually concrete amount reaches 35m
3More than, amount of reinforcement surpasses 2 tons, and the about 15-20 of construction period days, nearly 30,000 yuan of cost.Engineering completion back concrete foundation becomes underground discarded object, for urban construction from now on stays underground obstacle.
Summary of the invention
The purpose of this utility model has provided a kind of pillar crane cross steel work basis, and cross steel work basis substitutes traditional reinforced concrete foundation, and cost is low, and is reusable, easy installation and removal.
The technical scheme that its technical problem that solves the utility model adopts is: pillar crane cross steel work basis, main girder steel adopts worker's shaped steel or II shaped steel to be welded with time girder steel, use bottom wing then along connecting steel plate and linking girder steel and main girder steel, inferior girder steel are cross connect into integral body, connected mode adopts welding or high-strength bolt to connect.Main girder steel directly is connected with the tower crane foundation joint with time girder steel top, and main girder steel is disposed steel plate with time girder steel bottom with bored pile or back, hand excavated pile stake top and is connected.After the engineering completion, the connecting bolt repeated use of can cutting to only need be taken off in pillar crane cross steel work basis.
The purpose of this utility model provides a kind of pillar crane cross steel work basis and replaces the cast-in-situ steel reinforced concrete tower crane foundation.Its beneficial effect is: cost low (about 2.5 ten thousand yuan of disposable cost of manufacture, reusable), and short construction period (installed only 1-2 days at the girder steel scene), construction is not subjected to weather influence, and easy installation and removal is environmental.
Description of drawings
Fig. 1 is a pillar crane cross steel work foundation layout plan.
Fig. 2 is the A-A sectional drawing of Fig. 1.
Fig. 3 is that the cross girder steel is connected full-page proof with the stake top.
1 bored pile or hand excavated pile 2 main girder steels 3 link on 4 girder steel 5 tower crane foundations of girder steel joint 6 bottom wing and dispose the weldering of steel plate 9 consents after connecting 8 tops of steel plate 7 high-strength bolts among the figure
The specific embodiment
The cross girder steel is processed in advance in factory, main girder steel adopts worker's shaped steel or II shaped steel to be welded with time girder steel, use bottom wing then along connecting steel plate and linking girder steel and main girder steel, inferior girder steel are cross connect into integral body, connected mode adopts welding or high-strength bolt to connect.When finishing, the tower crane foundation pile driving construction reaches curing period, cut a top laitance to design elevation, back, stake top is installed disposes steel plate 8, then, a disposal steel plate 8 behind the top on main girder steel 3 and time girder steel 4 and the bored pile 1 is connected, and it is to weld with the pile body reinforcing bar employing consent weldering 9 of bored pile 1 that back disposal steel plate 8 is pushed up in stake.Tower crane foundation joint 5 is directly installed on main girder steel 2 and time girder steel 4, tower crane foundation joint 5 is connected with model employing high-strength bolt or the typing welding base of time girder steel 4 connected modes according to pillar crane with cross master girder steel 2, can move after the assay was approved.
After the engineering completion, remove tower crane, lay down cross master girder steel 2 and time girder steel 4 end high-strength bolts 7, promptly dismountable cross master girder steel 2 and 4 transitions of time girder steel are reused.
Claims (2)
1, a kind of pillar crane cross steel work basis, its adopt steel work processing method with main girder steel (2), inferior girder steel (4), go up bottom wing along connecting steel plate (6), linking girder steel (3) and be assembled into cross steel work basis, it is characterized in that: main girder steel (2) adopts worker's shaped steel or II shaped steel to be welded with time girder steel (4), use bottom wing then and main girder steel (2) and time girder steel (4) are connected into integral body along connecting steel plate (6) and linking girder steel (3), connected mode adopts welding or high-strength bolt to connect, and is the cross layout after main girder steel (2) and time girder steel (4) are connected.
2, pillar crane cross steel work according to claim 1 basis, it is characterized in that: main girder steel (2) pushes up back disposal steel plate (8) with the stake on time girder steel (4) and the bored pile (1) and is connected, and the pile body reinforcing bar of disposing steel plate (8) and bored pile (1) behind the stake top adopts consent weldering (9) to weld.
