Abstract
The invention discloses a folding drawing steel internal mould system for a prefabricated hollow beam, which uses a steel structure and is provided with two semi-mould units with opposite openings at left and right sides on a cross section of the internal mould. The semi-mould unit is formed by an upper unit plate and a lower unit plate which are hinged at the side to form a hinge structure capable of unfolding or folding up and down. In the semi-mould unit, a pull rod is arranged along the length direction of the internal mould. The pull rod is hinged respectively with the upper plate unit at the top plate through a group of upper connecting rods arranged at intervals and hinged with the lower unit plate at the bottom plate through a group of lower connecting rods arranged at intervals. In the invention, the pull rod is drawn so that the internal mould is respectively in unfolding and folding states. The invention does not need to disassemble manually and is particular suitable for prefabricating hollow beams with small sections, and improves the work efficiency greatly.
Description
Technical field
The present invention relates to the steel-made internal mould system of prefabricated hollow beam.
Background technology
The internal model structure size of prefabricated hollow beam depends on the physical dimension of hollow beam itself, hollow beam physical dimension in practical application is of a great variety, take a kind of 10m hollow beam as example: this hollow joist steel internal mold length is as 10.9m, width are as 0.75m, highly as 0.36m, and existing interior modular form exists respectively following problem:
A kind of gasbag-type internal mold, but easily damaged, turnover rate is low, and after air bag breakage, needs specialized factory to repair, maintenance difficult, maintenance cost is high; Gasbag-type internal mold is from heavy and light, and hollow beam gasbag-type internal mold when prefabricated easily floats, and hollow beam quality is difficult to guarantee.
A kind of bamboo rubber sheet type internal mold, is comprised of bamboo offset plate and inner support, but the perishable damage of bamboo offset plate, turnover rate is low, and use cost is high; Its inner supporting structure need to be by manually dismantling, but for width be 0.75m, highly for the small bore hollow beam of 0.36m, manually cannot enter dismounting.
Summary of the invention
The present invention is for avoiding the existing weak point of above-mentioned prior art, and the prefabricated hollow beam folding slide steel inner formwork system that provide a kind of sound construction, be easy to dismounting, use cost is low adopts the form of pull to avoid manually entering.

Deployed condition position: pull bar pushes, upper connecting rod and lower link are vertically, and vertical with pull bar, and the hinge that the upper cell board in half form unit and lower unit plate form launches, and two and half form units dock the inside cavity that forms sealing on top board and base plate position;
Rounding state position: pull bar pull-out, upper connecting rod and lower link are inclination, and the hinge that the upper cell board in half form unit and lower unit plate form draws in can pull state for folding.
The design feature of foldable drawing type steel inner mold system for prefabricated hollow beam of the present invention is also:
Described two and half form units are to be arranged in the upper cell board of half form unit of a side the upper cell board formation of half form unit that is arranged in a right side is withheld at top board and the locational docking of base plate.
The back of cell board and lower unit plate arranges respectively the horizontal rib in longitudinal rib He Ge road on described.
Upper cell board and lower unit plate in described half form unit are directly hinged at sidepiece; Or upper cell board and lower unit plate are fixedly connected with respectively the hinged ear that stretches to template center at sidepiece, hinged to be partial to the hinge hole of internal mold center one side on described hinged ear.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention is the version of folding pull, utilizes hoist engine to draw and can, by the internal mold demoulding pull-out from complete prefabricated hollow beam, without artificial unloading, be particularly suited for the prefabricated of small bore hollow beam pull bar in internal mold, can improve significantly work efficiency;
2, the present invention adopts steel construction, and internal mold, from great, has effectively been avoided internal mold floating, guarantees the prefabricated quality of hollow beam;
3, steel construction internal mold intensity of the present invention is high, not fragile, and turnover utilization rate is high, can effectively reduce use cost.

The specific embodiment
Referring to Fig. 1 and Fig. 3, in the present embodiment, foldable drawing type steel inner mold system for prefabricated hollow beam is to adopt steel construction, on internal mold cross section, is a first from left and parts body on the right side two and half form units that opening is relative are set; Each half form unit is respectively hinged at sidepiece by upper cell board 1 and lower unit plate 2, the hinge structure that formation can launch up and down or draw in;
In each half form unit, along internal mold length direction, pull bar 3 is set, pull bar 3 is hinged on top board position with upper cell board 1 with one group of spaced upper connecting rod 4 respectively, and hinged on base plate position with lower unit plate 2 with one group of spaced lower link 5;
Adopt the version in the present embodiment, by operation pull bar 3, can make inner mold have following two mode bits:
Deployed condition position shown in Fig. 1 and Fig. 3: pull bar 3 pushes, upper connecting rod 4 is vertical with pull bar 3 with lower link 5, the hinge that upper cell board 1 in half form unit and lower unit plate 2 form launches, and two and half form units dock the inside cavity that forms sealing on top board and base plate position;
Rounding state position shown in Fig. 2 and Fig. 4: pull bar 3 pulls out, upper connecting rod 4 and lower link 5 are inclination, and the hinge that the upper cell board 1 in half form unit and lower unit plate 2 form draws in can pull state for folding.
In addition, as shown in Figure 1, in order to make template structure on top board and base plate position more firm, shown in Fig. 1, two and half form units are to be arranged in the upper cell board of half form unit on right side the upper cell board formation of half form unit that is arranged in left side is withheld at top board and the locational docking of base plate.In order to guarantee the solid and reliable of each connecting portion, need to be on each the back of cell board 1 and lower unit plate 2 longitudinal rib 6 horizontal ribs 7 in He Ge road are set respectively, the connection between each member is to be connected to longitudinal rib 6 or laterally on rib 7.
In concrete enforcement, also there is variable cross-section hollow beam structure as shown in Figure 5; Because hollow cavity width on II-II cross section place is greater than the hollow cavity width on I-I cross section place.In order to guarantee that internal mold is not subject to the impact of width can be by along pulling out hollow beam, internal model structure is set on I-I cross section place as shown in Figure 5 a, internal model structure is set on II-II cross section place as Fig. 5 b, wherein, shown in Fig. 5 a, the upper cell board 1 in half form unit and lower unit plate 2 are directly hinged with bearing pin at sidepiece; Upper cell board 1 shown in Fig. 5 b in half form unit and lower unit plate 2 are fixedly connected with respectively the hinged ear 8 that stretches to internal mold center at sidepiece, to be partial to the hinge hole 9 of internal mold center one side on hinged ear 8, realize hinged between upper cell board 1 and lower unit plate 2, can dwindle like this internal mold and receive the width after disturbing, the internal mold that on II-II section, width is larger can be pulled out smoothly from I-I light section.
Operating process:
1, according to the residing height of pull bar in internal mold and internal mold length, hoist engine is installed, is guaranteed steel wire rope and the hollow beam 11 longitudinal centre line keeping parallelisms of hoist engine, and hoist engine mounting distance meets the required minimum range of dismounting internal mold;
2, utilize hoist engine to draw pull bar in internal mold, first remove side half form unit, by the version shown in Fig. 1, first should remove half form unit that is positioned at right side, remove again subsequently half form unit that is positioned at left side, avoid phase mutual interference.
