Abstract

The utility model discloses a foldable embedded sleeve device which comprises three pipe walls, two sets of hinges, a bolt, a long bolt hole and a short bolt hole. The three pipe walls are connected through the two sets of hinges so that a circular pipe can be formed. The long bolt hole is welded to the inner side of the opening position of the circular pipe, the short bolt hole is welded to the outer side of the opening position of the circular pipe, and the long bolt hole and the short bolt hole are connected through the bolt. The foldable embedded sleeve device is simple in structure, convenient to use and capable of effectively solving the problem that in the building construction field, after concrete is set, an embedded sleeve is not prone to being pulled out and completely satisfying the requirement for the arrangement of a reserved hole in the building construction field.

Description

A kind of collapsible service sleeve device

Technical field

The utility model relates to a kind of collapsible service sleeve device, especially a kind of a kind of collapsible service sleeve device that is applied to the realm of building construction.

Background technology

The modern architecture required function is more, in order to meet the demand of engineering construction, a large amount of hole to be provideds need to be set in construction, in the middle of construction, the main method of service sleeve that adopts arranges hole to be provided at present, but traditional service sleeve condenses due to concrete in construction, cause it not to be drawn out easily, have a strong impact on the progress of successive projects.

Summary of the invention

In order to overcome the difficult problem that service sleeve is not drawn out easily in the middle of building operations, the utility model provides a kind of collapsible service sleeve device.

The technical scheme that the utility model provides is, a kind of collapsible service sleeve device, and this device comprises three tube walls, two combined page, a latch, an espagnolette bolt hole and a short latch hole, described two combined page connect into pipe by three tube walls; The espagnolette bolt eyelet welding is connected on the inboard at circular tube open place, and the short latch eyelet welding is connected on the outside at circular tube open place, and both connect by latch.

In order to guarantee can firmly using safely of embedding pipe fittings, this utility model has also increased a fixed head, a stay hook and the parts such as nut, pipe and bottom that wherein stay hook forms through three tube walls are fixed, fixed head is positioned over edge on tube wall through stay hook, and nut is tightened on fixed head by stay hook.

For the ease of operation in the middle of construction, on the pipe that the utility model forms at described three tube walls, be welded with two handles of handle.

Collapsible service sleeve device provided by the utility model is after extracting latch, and two tube walls can move inward, and can have enough spaces to separate with concrete, can reach good separating effect.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is elaborated.

As shown in accompanying drawing 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, this device comprises handle 1, tube wall 4, hinge 2, latch 3, espagnolette bolt hole 5, the short latch hole 9 of welding and tube wall inboard, fixed head 6, stay hook 7, nut 8, wherein two combined page 2; 12 by three tube walls 4; 10; 11 connect into pipe, and need to guarantee two combined page 2; 12 height and tube wall height are consistent; This espagnolette bolt hole 5 is welded on the inboard at circular tube open place, and espagnolette bolt 5 height and tube wall 4; 10; 11 height is consistent and near opening part, to avoid spillage.Short latch hole 9 is welded on the outside at circular tube open place, two pin holes 5; 9 connect by latch 3, and in construction, the pin hole position must be controlled well in addition, makes in the pipe closure and can insert the latch inertia each other afterwards; This stay hook 7 is through tube wall 4; 10; 11 pipes that connect to form and bottom are fixed; Fixed head 6 is positioned over edge on tube wall through stay hook 7, and nut 8 will be tightened on fixed head 6 by stay hook 7.

The course of work of the present utility model is as shown in Fig. 2, Fig. 3, Fig. 4, Fig. 5: in engineering construction, need the utility model preset in advance, after concrete coagulation, while needing to remove service sleeve, at first need to extract latch 3, then knocking a side pipe wall 4 makes it move inward the disengaging concrete, knock an adjacent side pipe wall 10 again and make it break away from concrete, finally knock tube wall 11 of residue and make the whole concrete that breaks away from of service sleeve, finally we utilize handle 1; 13 extract service sleeve smoothly.

The above describes embodiment of the present utility model by reference to the accompanying drawings, but the utility model is not limited to above-mentioned embodiment, in the ken possessed those of ordinary skills, can also make many variations to it.
