JPH0725396Y2 - Device for removing interstitial inclusions - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is directed to a device for removing interstitial material, more specifically, for removing styrofoam, a separator and other foreign matter left in the expansion (gap) of a building or a workpiece. It relates to a removing device for removing.

[Prior Art] For example, as shown in FIG. 8, when concrete buildings 1 and 1 are built close to each other at an interval of 10 to 20 cm, styrofoam 3 and a separator are placed in a gap 2 between the buildings 1 and 1. 4 is performed.

As described above, when the Styrofoam 3, the separator 4, etc. are left in the gap 2, noise or vibration is generated in the building, or the structure is constrained to generate cracks or the like, and thus these need to be removed. is there.

Conventionally, as a method of removing the styrofoam 3 and the like described above, a method of dissolving the styrofoam or the like with a solvent as a chemical method and a method of cutting with a core boring or a wire cutter as a physical method have been considered.

[Problems to be solved by the device]

By the way, the former chemical method has a problem that the solvent used is harmful to the human body and there is a risk of fire.

In addition, the latter physical method has a problem that a large amount of water is used for the removal work, so that water permeates the building wall from the boundary wall.

Therefore, in order to solve the above problems, the problem of the present invention is to form a gap that can physically and easily remove the Styrofoam, the separator, and other foreign matter left in the expansion without using a solvent or water. An object is to provide a device for removing inclusions.

[Means for Solving the Problems]

In order to solve the above problems, the present invention has a holding jig fixedly arranged at both ends of a gap, a removing member arranged so as to be movable between both holding jigs, and a holding member held at both ends of the gap. A winch that is arranged at the lower position of the jig and winds the wire connected to both ends of the removing member through the holding jig, and reciprocates the removing member between the holding jigs. It employs a structure provided with scraping metal fittings.

[Action]

A holding jig and a winch below the holding jig are fixed to both ends of a gap having an inclusion, and wires are connected to both ends of a removing member arranged between the holding jigs on the inclusion. The wire is wound with a winch through a holding jig, and both winches are operated to move the removing member back and forth between the holding jigs, and a scraping metal fitting provided under the removing member scrapes the inclusions. When the scraping progresses to some extent, both holding jigs are moved downward and the above operation is repeated, whereby the inclusions can be efficiently removed.

〔Example〕

An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, the removing device has holding jigs 11 and 11 which are fixedly arranged at both ends of a concrete building or a work piece sandwiching a gap.
And a removing member 12 arranged so as to be movable between the holding jigs 11 and 11, and a wire 13 fixedly arranged below the holding jigs 11 and 11 and connected to both ends of the removing member 12. It comprises winches 14 and 14 for winding 13 and a control device 15 for operating both winches 14 and 14 shown in FIG.

As shown in FIG. 4 and FIG. 5, the holding jigs 11 and 11 are
A horizontal shaft 17 is provided on a mounting base 16 formed by using a mold material, and a pulley 18 is attached to the shaft 17.

As shown in FIG. 6, the building 1, 1 or the workpiece to which the holding jigs 11 and 11 are fixed are fitted to the bolt holes 19 of the mounting base 16 on the outer surfaces of both ends sandwiching the gap 2. anchor
The 20 are mounted side by side in the vertical direction, and the fixing position of the holding jig 11 can be moved sequentially from the upper part to the lower part by the bolt 21.

As shown in FIGS. 2 and 3, the removing member 12 has pulleys 23, 23 attached to both inner ends of a main body 22 having a horizontally long rectangular tube shape. It has a structure in which the metal fittings 24, 24 are fixed, and both scraping metal fittings 24, 24 are bent toward the inner end side approaching each other in a downward arc shape toe tip 24a, 2
It has a bar shape with 4a.

The winches 14 and 14 are fixed to the ground below the both ends of the gap 2 directly or by providing a foundation, and the winch 14 and 14 are tuned and independently rotated by the controller 15.

As shown in FIG. 7, the control unit 15 includes power on / off switches 31, 32, switches 33, 34 for selecting either one of the winches 14, 14 for single use or both for simultaneous use, and one winch. Switch 3 for winding and unwinding
5, 36 and switches 37, 38 for winding and unwinding the winch on the other hand, and a switch for the winch on the other hand
Reference numerals 35 and 36 also serve as a double control for simultaneously operating both winches 14 and 14 when the switch 34 for simultaneous use is input.

Next, the removal of the Styrofoam 3 and the separator 4 which are present in the gap of the concrete building will be described.

As shown in FIG. 1, holding jigs 11 and 11 are attached to the upper portions of both ends of the concrete building 1 and the gap 2 between them, and winches 14 and 14 are fixed to the lower portions.

The removing member 12 is placed on the polystyrene foam 3 between the holding jigs 11 and 11.
, And the wire 13, which is pulled out from both winches 14 and 14,
13 is a removing member 12 via the holding jigs 11 and 11 pulleys 18 and 18.
It is wound around the pulleys 23, 23, and its ends are locked to the shafts 17 of the holding jigs 11, 11.

In this state, using the control device 15, first, one winch is wound and actuated to tension the wires 13, 13, and then both winches 14, 14 are tuned and rotated so that one winches the wire and the other unwinds the wire. The removing member 12 and the holding jig 11.
The styrene foam 3 and the separator 4 are gradually scraped from the upper part by scraping metal fittings 24, 24 fixed to the lower surface of the removing member 12 by reciprocating between 11.

When the scraping progresses, the wires 13 and 13 loosen. Therefore, if the wire is wound up by one of the punches and the wires 13 and 13 are tensioned each time, the tension stress of the wire 13 and the weight of the removing member 12 cause the foamed polystyrene 3 to separate. The separator 4 can be scraped off.

When the removing member 12 descends on the line connecting the holding jigs 11 and 11 by scraping, the holding jigs 11 and 11 are moved to the lower position, and the removing member 12 is reciprocally moved in the same manner as described above. By sequentially repeating the above, the Styrofoam 3 and the separator 4 can be completely removed.

〔effect〕

As described above, according to the present invention, styrofoam, separators and other foreign matter remaining in the gaps between buildings and workpieces can be mechanically and efficiently scraped off, and noise, vibration, and cracks in buildings and workpieces can be removed. It is useful for preventing cracks.
