Abstract
The invention discloses a rear-mounted eccentric screw system for formwork erection, and belongs to the technical field of formwork erection of buildings. When crossed longitudinally and transversely, the existing screws for formwork erection can intervene to one another and are single in function. The rear-mounted eccentric screw system for formwork erection comprises a double-end screw, round nuts, outer screws, a shaping square stopper, eccentric guide sleeves and a chuck, wherein the round nuts are connected to two ends of the double-end screw; the outer screws are connected to the round nuts; bayonet locks are fixed on the outer screws; positioning through holes which correspond to through holes of screws on a formwork are formed in the shaping square stopper; the eccentric guide sleeves can be rotatably placed in the positioning through holes of the shaping square stopper; each eccentric guide sleeve is provided with an eccentric adjusting hole; the outer screws and the bayonet locks can penetrate in the eccentric adjusting holes of the eccentric guide sleeves; the chuck is provided with through holes; the outer screws and the bayonet locks can penetrate in the through holes; and the chuck rotates so that the bayonet locks are clamped at the edges of the through holes. During formwork erection, the eccentric guide sleeves rotate so as to adjust skewing of the outer screws, the circumstance that the screws which are crossed longitudinally and transversely intervene to one another is avoided, the screw can be mounted at the rear of the formwork, and the rear-mounted eccentric screw system is convenient and flexible to operate; and moreover, the rear-mounted eccentric screw system has effects of pulling the formwork, supporting the formwork when the formwork is mounted and assisting in detachment of the formwork when the formwork is detached.

Detailed description of the invention
Below in conjunction with Figure of description, the present invention will be further described.
Formwork of the present invention with rearmounted eccentric screw system as shown in figs. 1-7, it comprises:
A double threaded screw 01 (see Fig. 1) between two parallel templates;
Two round nuts 02 (see Fig. 1), each round nut is connected to one end of double threaded screw 01 by screwed hole;
Two external screw rods 03 (see Fig. 1), every root external screw rod 03 is connected with the screwed hole of a round nut 02, external screw rod 03 is fixed with bayonet lock 31;
For leaning against the sizing side's shelves 04 (see Fig. 4 A-6B) on template lateral surface, it is offered the positioning through hole 41 of screw rod perforation in corresponding templates for two;
Two eccentric guide pin bushings 05 (see Fig. 3 A-3B), in the rotating positioning through hole 41 being placed in sizing side's shelves 04 of each eccentric guide pin bushing 05 (see Fig. 5 A-5C), each eccentric guide pin bushing 05 has an eccentric adjusting hole 51 passed for external screw rod and bayonet lock;
Two chucks 06, all have a through hole 61 (see Fig. 6 A-6B) passed for external screw rod and bayonet lock, rotate this chuck and make bayonet lock 31 be stuck in the edge of through hole 61.
During formwork, two round nuts 02 are connected to one end of double threaded screw 01, can after template be in place, again the double threaded screw linked together and round nut are placed between parallel template, respectively two external screw rods 03 are connected to a round nut 02 outside template again, according to the specification of setting, the outer end of round nut is just supported on the medial surface of template; (see Fig. 5 A-5C on the lateral surface that two sizing side's shelves lean against two parallel templates respectively, the diagram in template and template is omitted) in figure, two eccentric guide pin bushings 05 to be enclosed within respectively on external screw rod 03 and to be placed in the positioning through hole 41 of sizing side's shelves 04, rotating eccentric guide pin bushing 05 makes the eccentric adjusting hole 51 on it go to proper angle (see Fig. 5 C), thus makes external screw rod can depart from center in eccentric adjusting hole 51 and regulate its position in the height direction (diameter that the diameter of the screw rod perforation in template is greater than external screw rod makes external screw rod to regulate); Two chucks 06 are enclosed within two external screw rods 03 respectively, rotating chuck 06 makes bayonet lock 31 be stuck in the outward flange of through hole 61, tentatively fixing to screw rod, be convenient to other structure is installed on external screw rod and attaching nut on the outer end screw thread of external screw rod again, make installation process more convenient and quicker.
Accordingly, by being departed from by the screw rod intersected in length and breadth, center can avoid screw rod in corner, the interference of wall column, wall wall infall is in length and breadth fought; How much screw rod short transverse is adjustable depends on the offset in eccentric adjusting hole and the rotational angle in eccentric adjusting hole, when the offset in eccentric adjusting hole is enough large, only regulating the screw rod in the direction intersected in length and breadth and adjustable enough offsets to avoid the interference of infall in length and breadth to fight, is that the screw rod intersected in length and breadth is avoided interfering fought respectively to upper, downward bias in-migration shown in Fig. 7.
For the ease of being taken off by round nut 02 after casting, the outer end of round nut 02 is provided with hexagon ring 21 (see Fig. 2), and after pulling down template, round nut is pulled down by available inner hexagon spanner.Especially, round nut 02 is in frustum, and its large end toward the outer side, thus is more convenient for round nut to take off and fills up the cavity of round nut position.
In order to be taken off by double threaded screw after pouring, the external diameter of double threaded screw screw thread is not more than the diameter of double threaded screw.Especially, double threaded screw overlaps to have and shirks sleeve pipe, be beneficial to double threaded screw and extract from shirking sleeve pipe, after extracting double threaded screw, shirk sleeve pipe and stay in concrete body.
The external diameter of external screw rod screw thread is not more than the diameter of external screw rod.
The end of the side's of sizing shelves 04 is provided with accepts falcon mouth 42 (see Fig. 4 A-4B), for accepting up and down.
Positioning through hole on eccentric guide pin bushing, the side's of sizing shelves is coniform and can match.
For the ease of dismounting template, external screw rod 03 is fixed with lean against on round nut and be supported on and template medial surface takes over a business 32, when formwork, this takes over a business the medial surface that 32 parts treating as round nut are supported on template; During dismounting template, back out external screw rod 03, then template 32 is outwards pushed open by taking over a business on external screw rod; be convenient to template and depart from concrete body; especially connect into and provide convenience compared with the form removal of macroplate template, had good protection to template on the one hand, on the other hand also for operation provides conveniently.
Concrete, take over a business to be welded on external screw rod, bayonet lock is welded on external screw rod.
Chuck 06 is provided with inner hexagonal hole 62, pulls chuck rotate by inner hexagon spanner.
