Description

Anticreep creeping formwork switching-over box

Technical Field

The utility model relates to a construction technical field specifically is an anticreep creeping formwork switching-over box.

Background

The climbing formwork is called as the jumping formwork for short, and is an advanced formwork construction process suitable for cast-in-situ reinforced concrete structure of high-rise building or high-rise structure. Depend on building vertical structure at the structure construction stage, rise along with the successive layer of structure construction, the template can not occupy the construction site like this, also need not other perpendicular transportation equipment. The climbing device consists of climbing templates, climbing frames, climbing rails and other equipment, and is an effective tool in constructing high-rise structures such as a shear wall system, a cylinder system, piers and the like. Because of the self-climbing capability, the lifting of hoisting machinery is not needed, the lifting workload of the transportation machinery in construction is reduced, and the external scaffold in the construction process can be saved by hanging the scaffold on the self-climbing template. Therefore, the climbing formwork can reduce the number of hoisting machines and accelerate the construction speed, thereby having better economic benefit and being particularly suitable for building multi-storey or high-rise buildings on narrower fields.

The climbing formwork reversing box is a device installed on a climbing rail, the climbing rail is fixed on a concrete wall, the angle of a tongue body which can rotate in the climbing formwork reversing box is changed, the tongue tip of the tongue body can be clamped with a bearing ladder rail on the climbing rail, and then the load fixed on the reversing box can be fixed on the wall surface, and the load does not slide down or fall.

Disclosure of Invention

The utility model provides an anticreep creeping formwork switching-over box, its with climb the track fixed contact after, through the inside outstanding embedded structure of casing, avoid the switching-over box to deviate from the track that climbs at the slip in-process, cause the phenomenon that the structure pine takes off.

In order to realize the above the utility model discloses an aim, the technical scheme who adopts is:

the utility model provides an anticreep creeping formwork switching-over box, sets up the spout on the casing, and the spout inlays with the creeping rail and slides, sets up rotatable tongue in the casing, sets up the back plate behind the tongue, and the tongue is articulated with the casing through tongue pivot, and tongue pivot end fixing sets up the axle handle, still articulates the switching-over handle on the casing, and the axle handle is connected with the switching-over handle through the extension spring. The reversing handle rotates to two positions, the handle is positioned below or above the rotating shaft, when the handle is pulled from the upper part to the lower part, the tension spring pulls the shaft handle to drive the rotating shaft of the tongue body to rotate the tongue body, the tongue tip at one end of the tongue body protrudes out of the shell, and the right-angle side is supported above the step of the climbing track, so that the reversing box and the climbing track are relatively positioned; when the box that needs to commutate slides, pull the top with the switching-over handle, the spring pulls the axle handle, and the tongue body rotates about 90, and tongue point right-angle side switching-over, hypotenuse can't support the ladder shelves, and then realize the removal of switching-over box.

A sliding groove on the shell corresponds to the groove in the middle of the climbing rail and is provided with a flange; the flange has two positions, one is located at the upper part of the shell, the other is located at the lower part of the shell, and the two protruding parts always keep the reversing box in the middle part of the climbing rail in the sliding process of the reversing box, so that the lateral displacement cannot occur.

The shape of the tongue body is two tongue points of a mirror image, the middle of the two tongue points is a convex arc shape, and the edge of the convex arc is always kept in the groove position in the middle of the climbing rail when the convex arc rotates. The existence of convex circular arc has just guaranteed, no matter the tongue body is under slip or non-slip state, through convex circular arc's limiting displacement, guarantees that the tongue body can not deviate from outside climbing orbital spout, plays the effect of anticreep.

The cross section of the transmission part of the rotating shaft of the tongue body is hexagonal and corresponds to the hexagonal shaft hole of the tongue body. The cooperation in hexagonal pivot and hexagonal shaft hole has realized that the tongue body can rotate along with the rotation of tongue body pivot, can not take place the phenomenon of skidding.

Compared with the prior art, the invention has the substantive characteristics and the progress that:

1. the utility model discloses the switching-over box with climb between the track, through the design of protruding portion and tongue shape, have fine anticreep effect, no matter at the in-process that climbs, or the location state, all have the technological effect that limit structure prevented the switching-over box and deviate from.

2. The utility model discloses the structure is succinct, and it is convenient to maintain, and is applicable in original creeping formwork system, need not to carry out the change of other parts during the improvement.

Detailed Description

Example 1

The utility model provides an anticreep creeping formwork switching-over box, sets up spout 2 on the casing 1, and spout 2 inlays with climb rail 9 and slides, sets up rotatable tongue 4 in the casing 1, sets up back plate 5 behind the tongue 4, and the tongue 4 is articulated with casing 1 through

tongue pivot

6, and 6 end fixing of tongue pivot set up the axle handle 7, still articulated reversing handle 8 on the casing 1, and the axle handle 7 is connected with reversing handle 8 through extension spring 11.

The sliding groove 2 on the shell 1 corresponds to the groove position in the middle of the climbing rail 9 and is provided with a protruding part 3 from top to bottom.

The shape of the tongue body 4 is two tongue points of a mirror image, the middle of the two tongue points is a convex arc shape, and the edge is always kept in the groove position in the middle of the climbing rail 9 when the convex arc rotates.

The cross section of the transmission part of the tongue body rotating shaft 6 is hexagonal and corresponds to the hexagonal shaft hole of the tongue body 4.

As shown in fig. 6, when the reversing wrenches of the upper reversing box 12 and the lower reversing box 13 are simultaneously pulled upwards, the lifting of the rail can be realized in the process of repeated extension and retraction of the jack 14. When the reversing wrenches of the upper reversing box 12 and the lower reversing box 13 are simultaneously wrenched downwards, the load can be lifted (namely, the formwork climbing frame body) in the process of repeated extension and retraction of the jack 14.
