Abstract
The utility model discloses a withdrawable internal mold for small cavity beams in bridge construction. The existing rubber air bag is easy to float up during casting construction, the concrete thickness of a top plate is difficult to be ensured, and the removal difficulty of wooden molds after the casting construction is high. The utility model is characterized in that reinforcing ribs are welded on reinforcing rods at certain intervals, connecting rods are respectively hinged and connected with the reinforcing rods and main pulling rods for forming a mold plate body frame, hanging rings are respectively welded on the ends of the reinforcing rods and the main pulling rods, and two corresponding hanging rings are connected through regulating rods. Because the rods are mostly connected through hinging joint, the shapes of the mold plates can be changed through extending or retracting the regulating rods, and the mold plates can be withdrawn from the cavity. When the withdrawable internal mold is in use, small cavity internal molds in various shapes can be manufactured according to the requirements of the internal mold technology, the utility model is suitable for the construction of various small cavity beams, the internal mold of the same beam bodies can be reused, and the utility model has the advantages of high circulating speed, easy mold plate processing, light weight, convenient operation, improved internal mold removing speed of the small cavity beams, high reassembling speed and capability of reuse.
Description
Technical field
The utility model relates to a kind of bridge construction equipment, specifically is the pullable internal mold of a kind of loculus body beam, belongs to the road construction technical field.
Background technology
Loculus body beam is exactly the narrow and small beam of design intracavity space in the precast bridge beam body, personnel enter beam body built-in function limited space, operation easier is big, the consumption worker is bigger, what loculus body beam internal mold adopted at present is rubber pneumatic bag or wooden model, and all there is defective in these two kinds of methods, and rubber pneumatic bag is when concreting, air bag floats easily, and concrete roof thickness is difficult to guarantee; When adopting wooden model to build, it is big to remove difficulty after the concrete setting, and built-up time is long once more to remove the back internal mold, and wooden internal mold is after once using, and assembling can be all not intact once more, so cost is higher, waste greatly; Be retained in the wooden model of beam intracoelomic cavity in addition, at the beam body during because of variations in temperature stretch-draw or in operation, have a potential safety hazard.
The utility model content
In order to overcome the deficiency that present loculus body beam internal mold uses air bag, wooden model to exist, the utility model provides a kind of loculus body beam pullable internal mold, with the speed of raising loculus body beam internal mold dismounting, and the quality of raising bridge construction.
The technical scheme that the utility model adopted is:
Last ribs is hinged respectively with corresponding following ribs, form one group of ribs, one group of ribs of welding vertically whenever keeps at a certain distance away on bracing piece, connecting rod longitudinal separation certain distance is hinged with bracing piece and main tie respectively, form the main template body framework, in one week of main body frame outer rim panel is set, bracing piece and main tie termination be welding hanging ring respectively, connect by adjusting rod between two corresponding suspension ring, the one group of ribs in end connects with bolt by junction plate.
The utility model can be suitable for the construction of various loculus body beams, and is applied widely, the efficiency of construction height, and same beam body internal mold can be reused, the turn-around speed height, template processing is simple, in light weight, easy to operate.Improved the speed of loculus body beam internal mold dismounting, assembling speed is fast once more, and can reuse, and cost is low.
Description of drawings
Accompanying drawing 1 is looked cross-sectional view for the master of the utility model embodiment.
Accompanying drawing 2 is the side-looking cross-sectional view of accompanying drawing 1A-A direction.
Description of reference numerals is as follows:
Main tie 1, bracing piece 2, connecting rod 3, panel 4, adjusting rod 5, last ribs 6, following ribs 7, junction plate 8, suspension ring 9.
The specific embodiment
Below provide an embodiment and in conjunction with the accompanying drawings the utility model done and describe in further detail:
Going up ribs (6) for two is hinged respectively with corresponding two following ribs (7), form one group of ribs (6,7), go up vertical every interval 50cm at bracing piece (2) and weld one group of ribs (6,7), per four connecting rods (3) are one group, every group of connecting rod (3) longitudinal separation 50cm is hinged with bracing piece (2) and main tie (1) respectively, form the main template body framework, in one week of main body frame outer rim panel (4) is set, bracing piece (2) and main tie (1) termination difference welding hanging ring (9), connect the one group of ribs (6 in end between corresponding two suspension ring (9) by adjusting rod (5), 7) connect with bolt by junction plate (8).
The utility model is cut apart loculus body internal mold, most rod members adopt articulated form to connect, the flexible shape of template that makes it by adjusting rod changes, thereby can come out from pull in the little cavity, and the loculus body internal mold that only needs during use to make multiple shape according to the inner mould technology needs gets final product.
Claims (2)
1. the pullable internal mold of bridge construction loculus body beam, it is characterized in that ribs (6) and corresponding following ribs (7) are hinged respectively forms one group of ribs (6,7), one group of ribs (6 of welding vertically whenever keeps at a certain distance away on bracing piece (2), 7), connecting rod (3) longitudinal separation certain distance is hinged with bracing piece (2) and main tie (1) respectively and forms the main template body framework, in one week of main body frame outer rim panel (4) is set, bracing piece (2) and main tie (1) termination difference welding hanging ring (9), connect the one group of ribs (6 in end between corresponding two suspension ring (9) by adjusting rod (5), 7) connect with bolt by junction plate (8).
2. the pullable internal mold of bridge construction loculus body beam according to claim 1, it is characterized in that going up ribs (6) for two is hinged respectively with corresponding two following ribs (7), form one group of ribs (6,7), go up vertical every interval 50cm at bracing piece (2) and weld one group of ribs (6,7), per four connecting rods (3) are one group, every group of connecting rod (3) longitudinal separation 50cm is hinged with bracing piece (2) and main tie (1) respectively, form the main template body framework, in one week of main body frame outer rim panel (4) is set, bracing piece (2) and main tie (1) termination difference welding hanging ring (9), connect the one group of ribs (6 in end between corresponding two suspension ring (9) by adjusting rod (5), 7) connect with bolt by junction plate (8).
