Description

[Technical field]

[0001] The present invention relates to a rebar washer and a rebar washer system used to remove concrete and the like adhering to rebars when pouring concrete. [Background technology]

[0002] In construction work, with the aging of craftsmen and workers and the increase in the number of female workers, there is a high demand for labor-saving in manual work. One such work is the washing of reinforcing bars in concrete pouring work. For example, in concrete pouring work, concrete and other contaminants may be attached to the exposed reinforcing bars in the area where concrete is poured. If concrete is poured while leaving the contaminants as they are, there is a risk that the adhesion between the poured concrete and the reinforcing bars will deteriorate.

[0003] Conventionally, workers would spray water on the rebar and scrub the surface of the rebar with a hand-held brush or the like to remove dirt such as adhering concrete. Since washing rebars by hand is a laborious task, it is possible to use, for example, a high-pressure washer. Patent Document 1 describes a high-pressure washer for washing the surface of steel plates and the like. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2004-25163 A Summary of the Invention [Problem to be solved by the invention]

[0005] Manual rebar washing using a brush requires a lot of strength, and the time and results vary greatly depending on the worker. It is especially desirable to be able to wash rebars without relying on the worker, so that weaker or older workers can do the same work. When using a high-pressure washing device, dirt on concrete can be removed in a short time without relying on the worker, but the device is large and costs are high.

[0006] To provide a rebar washer and a rebar washer system that can remove dirt such as concrete adhering to rebars relatively cleanly in a relatively short working time, without using large-scale equipment and without depending on the worker, even by a weak or elderly worker. [Means for solving the problem]

[0007] The reinforcing bar washer of the present invention is A portable cleaning gun that sprays rebar cleaning liquid (usually water) from a nozzle; a portable fluid bag for collecting the fluid to be delivered to the cleaning gun; a compressed air supply hose, one end of which is connected to the compressed air intake port of the cleaning gun in order to supply compressed air for liquid injection from the outside; a liquid supply hose communicating between a liquid supply port of the liquid bag and a liquid intake port of the cleaning gun; The present invention is characterized by the following features.

[0008] Furthermore, the reinforcing bar washer system of the present invention is configured by combining the reinforcing bar washer having the above-described configuration with an air compressor.

[0009] Here, the portable liquid bag may be one equipped with a body attachment such as a shoulder strap or waist strap. In particular, a backpack-type liquid bag carried by a worker on his / her back allows the worker to use both hands freely, making the work easier. In addition, since it is only necessary to route a compressed air supply hose, the worker can move freely in the work area and work more easily than when cleaning water is pumped to the cleaning gun from a water supply tank or the like installed in a fixed position. Effect of the Invention

[0010] According to the present invention, the force required for the work is small, and dirt such as concrete adhering to the reinforcing bars can be removed relatively cleanly in a relatively short working time without depending on the worker. Therefore, it is possible to realize a reinforcing bar washer and a reinforcing bar washer system that are particularly suitable for work by weak or elderly workers. [Brief description of the drawings]

[0011] [Figure 1] FIG. 1 is an explanatory diagram showing an example of a reinforcing bar washing machine system to which the present invention is applied. [Diagram 2] FIG. 1 is an explanatory diagram showing a rebar washing operation using a rebar washing machine system. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, an embodiment of a reinforcing bar washing system to which the present invention is applied will be described with reference to the drawings. Note that the present invention is not limited to the embodiment described below.

[0013] Explaining with reference to Fig. 1, a rebar washer system 1 according to this embodiment is composed of a rebar washer 10 and an air compressor 20 shown in phantom lines. The rebar washer 10 includes a cleaning gun 30, a backpack-style water storage bag 40 (liquid bag), a water supply hose 50 (liquid supply hose), and a compressed air supply hose 60.

[0014] The cleaning gun 30 comprises a handle 31 that can be held with one hand, an operating lever 32 attached to the handle 31, a thin cylindrical nozzle 33 extending in a straight line from the tip of the handle 31, and a nozzle outlet 34 extending in a direction bent at an obtuse angle from the tip of the nozzle 33. A compressed air passage (not shown) communicating with the nozzle 33 is formed inside the handle 31, and a water supply passage (not shown) joining the compressed air passage at a midpoint is also formed. A tip 61 of a compressed air supply hose 60 is connected to a compressed air inlet 35 at the rear end of the compressed air passage. A tip 51 of a water supply hose 50 is connected to a water inlet 36 at the rear end of the water supply passage.

[0015] The water storage bag 40 comprises a water storage bag main body 41 that stores water for cleaning rebars, and left and right length-adjustable shoulder straps 42, 43 attached to the left and right sides of the water storage bag main body 41. A water supply port 44 is opened at the upper end of the water storage bag main body 41, to which a rear end 52 of a water supply hose 50 is connected. Meanwhile, a connection port 62 at the rear end of a compressed air supply hose 60 is connected to the compressed air discharge port 21 of the air compressor 20.

[0016] Fig. 2 is an explanatory diagram showing the rebar washing work. A worker 70 performing the rebar washing work places an air compressor 20 in a position that does not interfere with the work at a work site 80, and connects a connection port 62 (see Fig. 1) at the rear end of a compressed air supply hose 60. The worker also carries a water storage bag 40 and holds a cleaning gun 30 in his hand, aims its nozzle outlet 34 at the dirty part (adhered concrete) of the rebar to be worked on (main rebar 91, stirrup 92, etc.), and operates an operating lever 32. Water is sprayed at high pressure from the nozzle outlet 34 to the dirty part of the rebar, such as concrete, and the dirt is removed.

[0017] Thus, in this example, a portable rebar washer 10 that sprays water at high pressure is used to reduce the labor required for rebar washing (removing concrete that adheres to rebars when concrete is poured), which was previously done manually. Rebar washing using the rebar washer 10 requires less strength from the worker than conventional brush washing. Also, compared to brush washing, dirt can be removed relatively cleanly in a relatively short working time without depending on the worker. Therefore, the rebar washer 10 of this example is particularly suitable for use by weak and elderly workers.

[0018] In addition, the components of the reinforcing bar washer 10 and the air compressor 20 of this embodiment can be commercially available products. Therefore, the reinforcing bar washer 10 and the system consisting of the reinforcing bar washer 10 and the air compressor 20 can be constructed at low cost.

[0019] Furthermore, various types of cleaning guns 30 with different nozzle shapes and apertures are commercially available, and many types of water storage bags 40 (water bags) with a range of capacities from large to small are commercially available. By appropriately setting these according to the worker and the work subject, rebar washing work can be performed efficiently. [Explanation of symbols]
