Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1-2, a kind of box girder formwork splicing lifting accessory appliance, is made up of following a few part:
Comprise bracket component 1, described bracket component is made up of vertical beam 110, the top rail 120 being vertically fixed on vertical beam the same side and lower transverse beam 130, the upper reinforcement cant beam 140 being arranged on top rail upper end and the lower reinforcement cant beam 150 that is arranged on lower transverse beam lower end.Upper and lower two crossbeams be arranged in parallel, between upper and lower two crossbeams, leave spacing, and this spacing forms the draw-in groove 160 that can match with box girder formwork edge of a wing end.The two ends of upper reinforcement cant beam are connected with the outer end of top rail and the upper end of vertical beam respectively, concrete, mode by welding connects, also in the two ends welded end plate of upper reinforcement cant beam, then with bolt, the end plate of corresponding end can be coupled together with the outer end of top rail and the upper end of vertical beam respectively.Like this, by arrange between vertical beam and top rail above-mentioned on strengthen cant beam, just above top rail, defining stable gusseted, thus ensure that top rail is when being subject to traction force upwards, can not there is flexural deformation upwards in top rail.The two ends of lower reinforcement cant beam are connected with the outer end of lower transverse beam and the bottom of vertical beam respectively.The two ends of lower reinforcement cant beam respectively with the concrete connected mode of the outer end of lower transverse beam and the bottom of vertical beam referring to above-mentioned upper reinforcement cant beam two ends respectively with the connected mode of the outer end of top rail and the upper end of vertical beam, do not repeat them here.Like this, by arranging lower reinforcement cant beam between vertical beam and lower transverse beam, just defining stable gusseted in the below of lower transverse beam, thus ensure that lower transverse beam is when being subject to downward pressure, can not there is downward flexural deformation in lower transverse beam.
Comprise positive stop 2, described positive stop is fixedly mounted on the medial surface of vertical beam bottom, and stretches out from a side of vertical beam.The concrete setting position of positive stop in vertical beam bottom and size, need to determine according to the deployment scenarios of the outside cross rib of case beam side.The effect of above-mentioned positive stop is: in the process of box girder formwork lifting, positive stop contacts with soldier, make vertical beam be in plumbness during lifting, limit this lifting accessory appliance because Long-Time Service causes upper and lower crossbeam slight deformation, and do not reach desirable result of use.
Comprise suspension ring 3, described suspension ring are being preferably fixedly connected with top rail adjustable along line direction in outer end in top rail.Like this, when using this lifting accessory appliance, just not needing the installation site deliberately looking for suspension ring, only needing in use, regulate the position of suspension ring, the position of centre of gravity of suspension centre and template is positioned on same vertical curve.In addition, the structure of suspension ring adjustable position, also meets the instructions for use that the box girder formwork position of centre of gravity of different size is different, thus has increased considerably the applicability of lifting accessory appliance.
In said structure, adjustable being fixed on top rail of suspension ring can adopt various structures to realize.In the utility model, described suspension ring preferably adopt following structure: the upright part 310 be arranged in parallel by two, the arcuation ejector rod part 320 be connected with two vertical rod upper ends, form with the detachable movable crossbar sections 330 be connected in two vertical rod bottoms and the fixed transverse rod part 340 be connected with the middle part of two vertical rods; Arc ejector rod part, two upright part and fixed transverse rod part are connected to form the main part of suspension ring, and the main part of suspension ring is arranged on the top of top rail.Suspension ring main part is when lifting by crane box girder formwork, the part be directly connected with the lifting rope of crane gear.Fixed transverse rod part, two upright part and movable crossbar sections are connected to form the portion of clamping, and the portion of clamping is sleeved on top rail.Adopt above-mentioned suspension ring structure, when needs are on top rail during mobile suspension ring (when changing the position of suspension centre), first the bottom of movable crossbar sections from two vertical rods is pulled down, then along top rail inwards or to external-adjuster suspension ring, after adjusting to the right place, movable crossbar sections is inserted to the bottom of two upright part, and locking activity crossbar sections, like this, fixed transverse rod part, movable crossbar sections and two upright part contact with the upper surface of top rail, lower surface and two sides respectively, thus realize suspension ring to be fixed on top rail.
In said structure, described top rail length is greater than the length of lower transverse beam, can ensure when box girder formwork mass centre changing like this, the flexibility adjusted before and after suspension ring.
In said structure, described vertical beam, top rail, lower transverse beam, upper reinforcement cant beam, lower reinforcement cant beam and positive stop all preferably adopt square steel structure.
Adopt this lifting accessory appliance to lift by crane box girder formwork 1 ', need two cover lifting accessory appliances to use simultaneously.Concrete, according to different box girder formwork length, two cover lifting accessory appliances are separated into suitable distance, to ensure that box girder formwork can keep balance at fore-and-aft direction when lifting.In addition, this lifting accessory appliance is adopted can to adopt the crane gear such as straddle truck or crane.
