Bolts penetrate through bolt holes in the ends of the horizontal supporting beams and penetrate through connecting holes A of supporting beam connecting plates, the bolts are tightened by nuts, the first horizontal supporting beam is connected with the connecting plates, the other two horizontal supporting beams are connected with the connecting plates in the same way, and a horizontal supporting system of the protective casing is formed by the three horizontal supporting beams. Thus, standard knots of the protective casing are obtained, and the other protective casing sections are installed in the same way.
Description
Technical field
the present invention is mainly used in the tower crane construction of construction work, also can be used for small-sized open caisson construction, belongs to building engineering construction field.
Background technology
At building engineering field, when general construction highrise building and annex, first to need to construct before deep pit digging tower crane, again tower crane is installed, to provide vertical transport and horizontal transport in follow-up deep pit digging and brace summer work progress, this situation ubiquity in modern construction engineering.General tower crane form of construction work is castinplace pile of first constructing, then is connected with filling pile head at natural ground level right position construction tower crane, forms the foundational system of tower crane, reaches absolutely, then install tower crane until tower crane concrete strength.In follow-up Deep Excavation, the castinplace pile supporting tower crane can expose outside soil layer, and construction equipment, particularly excavator may collide castinplace pile, obviously there is potential safety hazard; After building underground engineering construction completes dismounting tower crane, need again to remove tower crane and castinplace pile, time-consuming, extremely uneconomical.
Summary of the invention
the invention solves the problems referred to above, it utilizes open caisson construction principle, first 3 arc (1) combinations are mounted to a joint open caisson casing, often saving in casing merogenesis excavation, merogenesis sinking casing also installs next joint casing, until casing lower end sinks down into below deep foundation ditch floor, and tower crane of constructing in open caisson casing, be actually and current tower crane is moved to below deep foundation ditch floor by ground, avoid filling pile construction; When tower crane concrete strength reaches absolutely, in open caisson casing, merogenesis installs tower crane tower body until go out outside open caisson casing, continues outward to install tower crane tower body to whole tower crane installation at open caisson casing; When deep pit digging thereafter, open caisson casing can protect again tower crane tower body not collided by excavator, eliminates potential safety hazard; When building underground engineering construction is complete need dismantle tower crane time, only need dismantle tower crane and open caisson casing, tower crane is then embedded in below deep foundation ditch floor, and the open caisson casing of dismounting can also reuse, and saves a large amount of operating expenses.
the current tower crane of China generally adopts long 6 meters, the square foundation of wide 6 meters, certainly other base form is also had, for the ease of versatility of the present invention, tower crane of the present invention can be designed to the circular foundation of diameter 7 meters, open caisson casing is designed to the cylinder of diameter 7 meters equally, as the template of circular tower crane, can save foundation forms expense; Install for the ease of transport, the present invention is mounted to often to save open caisson casing by the combination of 3 arcs (1), often save open caisson casing height about about 2 meters, so the every sheet arc length about 7 meters of arc of the present invention (1), height 2 meters, thickness about 20 millimeters (thickness need be determined by design), weight about 2 tons, meet the requirement of urban road transport completely, the whole component of the present invention all can be mass, and can reduce manufacturing cost.
the present invention often saves open caisson casing and is connected to form by 3 arcs (1) and junction plate (2), adds 3 horizontal shore (3) composition horizontal struts systems, can form triangular support, reasonable stress, save material; In addition, the horizontal support that 3 horizontal shores (3) form, does not affect the installation of inter-chamber tower tower crane body.Certainly, open caisson casing also can be made up of 1,2 or multi-disc arc (1), does not affect essentiality content of the present invention.
the present invention is primarily of arc (1), junction plate (2), horizontal shore (3) composition; There is multiple connecting hole C(11 at arc (1) two ends); Junction plate (2) has multiple connecting hole B(7); Brace summer junction plate (8) is welded on junction plate (2), and brace summer junction plate (8) is with connecting hole A(4); Link slot (9) is welded on the upper end of arc (1), installs waterstop (10) in groove; Bolt (5) is through the connecting hole B(7 of junction plate (2)), the connecting hole C(11 of arc (1)) and tightening nuts (6) two panels arc (1) is connected, use the same method the 3rd arc (1) connection, three arcs (1) are connected to form a joint open caisson casing; The lower end of the arc (1) of a upper joint casing is inserted in next link slot (9) saving arc (1) upper end of casing and completes the connection saving casing up and down; There is bolt hole at horizontal shore (3) two ends, bolt is passed the bolt hole of horizontal shore (3) termination also through the connecting hole A(4 of brace summer junction plate (8)), tight a bolt connecting of first horizontal shore (3) and junction plate (2) with nut, use the same method and all the other two horizontal shores (3) to be connected with junction plate (2), three horizontal shores (3) form the horizontal struts system of casings; Need to illustrate: when junction plate (2) is connected with arc (1), between two plates, sealing rod is installed, prevents Groundwater infiltration; Bolt (5), nut (6) are all provided with water stop spacer with the contact surface of arc (1), junction plate (2), prevent Groundwater infiltration.

Detailed description of the invention
below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
see Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, first place, smooth open caisson position, lifting two panels arc (1), between junction plate (2) and the surface of arc (1), rubber fastening band is installed, by the connecting hole B(7 of bolt (5) through junction plate (2)), the connecting hole C(11 of arc (1)) and nut of screwing on (6) two panels arc (1) is connected, lift the 3rd arc (1) again, use the same method and be connected to form first segment open caisson casing with previous two panels arc (1), the earthwork in excavation open caisson, open caisson casing is sunk, after sinking to a joint casing height, waterstop (10) is arranged in the link slot (9) of first segment open caisson casing, again the lower end of second section casing arc (1) is inserted in the link slot (9) of first segment casing arc (1) upper end, the earthwork of second section height will be excavated and the second section casing that sinks in casing after 3 arcs (1) connections, use the same method and successively Section of three casing is installed, earth excavation and sinking casing are until casing lower end sinks down into design elevation, build bottom concrete, form the sealing hoistway of a safety.After open caisson drops to certain altitude, earth lateral pressure, by increasing, needs in heavy casing, install horizontal shore (3), and horizontal shore (3) two ends bolt is by connecting hole A(4) be connected to form horizontal struts system with junction plate (2); Certainly, for the sake of security, after well sinking completes, whole horizontal shores (3) should be installed; Finally, tower crane of constructing in open caisson, installs tower crane.When follow-up deep pit digging, open caisson casing can expose outside soil layer completely, and tower crane tower body can be protected not collided by excavator for casing or other facility collide, and eliminates potential safety hazard.When building underground engineering construction is complete need dismantle tower crane time, first need dismantle tower crane, more from top to bottom dismantle the horizontal shore (3) and arc (1) that often save casing successively, until all dismantled.
