Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a protective cap used to cover the tip of a set of reinforcing bars, and a purification device installation method.
[0002]
[Prior art]
In constructing a concrete building, a reinforcing bar group embedded in a concrete member, for example, a vertical bar protrudes to the outside, and the reinforcing bar group is often connected to a group of reinforcing bars called horizontal bars, for example. It is extremely dangerous if these vertical stripes are exposed until the final process.
[0003]
Therefore, conventionally, each tip of the reinforcing bar exposed on the ground is bent downward or a protective cap is attached to the tip.
[0004]
However, there is still a risk of injury even if each rebar tip is bent downward. In addition, since there are many exposed tips on the ground, the bending work takes a long time.
[0005]
Next, in the construction method in which the tip portion of each reinforcing bar is covered with a protective cap, there are many exposed tip portions on the ground covered with the protective cap, so that the operation is troublesome. In addition, the protective cap is removed, and the protective function is impaired.
[0006]
[Problems to be solved by the invention]
The subject of this invention is providing the protective cap which contributes to the safety | security improvement of the worker engaged in a reinforced concrete member construction work.
[0007]
Another object of the present invention is to provide an easy-to-handle protective cap that can cover the tip of a reinforcing bar group as a whole.
[0008]
[Means for Solving the Problems]
In order to solve the above-described problem, a protective cap for reinforcing steel bars according to the present invention includes a closing part on one side of one cavity part and an opening on the other side of the cavity part opposite to the closing part. Part. The closure is closed and the opening is open.
[0009]
The protective cap according to the present invention is used to cover at least one reinforcing bar group protruding from the concrete member.
[0010]
In this case, the protective cap according to the present invention includes a closing part on one side of one cavity part and an opening part on the other side of the cavity part opposite to the closing part, With the protective cap, the tip of the set of reinforcing bars can be covered as a whole. Since the tip of the reinforcing bar group is no longer exposed, the clothes or body of the worker will not be caught by the tip of the reinforcing bar, and will not be injured such as a cut or a scratch.
[0011]
In addition, since the protective cap covers not the single reinforcing bar but the tip of the set of reinforcing bars, the entire reinforcing bar group can be contracted and covered with a protective cap. For this reason, it can prevent that a protective cap slip | deviates easily. Therefore, according to the protective cap of the present invention, it is possible to prevent a decrease in safety due to the falling off of the protective cap.
[0012]
In addition, according to the present invention, the protective cap can cover the tip of a set of reinforcing bars as a whole reinforcing bar, so that the protective cap is compared with a case where a protective cap is attached to each reinforcing bar. The time for attaching can be greatly reduced. For example, when a set of three reinforcing bars is arranged at the four corners of the septic tank, according to the present invention, only four protective caps are provided, as compared with the conventional technology that requires as many as twelve protective caps. Just wear it.
[0013]
Furthermore, according to the present invention, since the protective cap can cover the tip of the set of reinforcing bars, the construction cost is reduced. As described above, since only a small number of protective caps are required to cover the tips of many reinforcing bars, the construction cost can be reduced. Moreover, since the same protective cap can be used over and over again, the construction cost can be further reduced.
[0014]
The protective cap which concerns on this invention is used in order to cover the at least 1 reinforcing bar group with which the concrete member was equipped in the purification apparatus installation method. In the installation method of the purification apparatus, a concrete member including at least one set of reinforcing bars is installed in a hole excavated in the ground. Next, a protective cap is put on the tip of the reinforcing bar group. The protective cap is the protective cap according to the present invention described above. Next, a septic tank is installed in the hole. The protective cap is removed at least after the hole is backfilled.
[0015]
According to the above purification device installation method, the tip of the reinforcing bar group is covered with the protective cap from the installation of the purification tank to the hole, which is the main process, to the backfilling of the hole. The safety of workers involved can be ensured. In addition, the time and cost required for installing the purification device can be reduced.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a front view of a protective cap according to the present invention, and FIG. 2 is a cross-sectional view of FIG. The illustrated protective cap includes a closure 91 on one side of the cavity 90 and an opening 92 on the other side of the cavity 90 opposite the closure 91. The closing part 91 is closed and the opening 92 is open. In this embodiment, the closing portion 91 is curved, which is merely an example. The protective cap can be made of plastic, metal, or a combination thereof.
[0017]
Further, the closing portion 91 is connected to the hollow portion 90. In other words, the closing portion 91 and the hollow portion 90 are formed of separate members and are connected to each other.
[0018]
FIG. 3 is a cross-sectional view showing a use state of the protective cap. As shown in the drawing, the respective leading ends 651 of the reinforcing bars included in the three reinforcing bar groups 65 protrude from the concrete member 60. The number of reinforcing bar groups 65 may be more or less than that illustrated.
[0019]
The protective cap 100 according to the present invention is used to cover the distal end portion 651 of at least one reinforcing bar group 65 protruding from the concrete member 60.
[0020]
In this case, the protective cap 100 according to the present invention includes a closing portion 91 on one side of one cavity portion 90, and an opening 92 on the other side of the cavity portion 90 on the side opposite to the closing portion 91. Therefore, the protective cap 100 can cover the tip end portion 651 of the set of reinforcing bar groups 65 as a whole. Since the distal end portion 651 of the reinforcing bar group 65 is no longer exposed, the clothes or body of the worker is not caught by the distal end portion 651 of the reinforcing bar and is not injured such as a cut or a scratch.
[0021]
Moreover, since the protective cap 100 covers not the single reinforcing bar but the tip 651 of the set of reinforcing bars 65, it is possible to prevent the protective cap 100 from being easily displaced. Therefore, according to the present invention, it is possible to obtain the protective cap 100 with high safety with less risk of dropping off.
[0022]
In addition, according to the present invention, the protective cap 100 can cover the tip 651 of the pair of reinforcing bar groups 65 as the entire reinforcing bar group 65. Therefore, when the protective cap 100 is attached to each reinforcing bar. In comparison, the time for attaching the protective cap 100 can be greatly reduced. For example, when a group of three reinforcing bars 65 are arranged at the four corners of the septic tank, according to the present invention, only four protections are required, as compared with the conventional technique where as many as twelve protective caps 100 are required. It is only necessary to attach the cap 100.
[0023]
Furthermore, according to the present invention, since the protective cap 100 can cover the front end portion 651 of the set of reinforcing bars 65, the construction cost is reduced. As described above, the construction cost can be reduced because only a small number of protective caps 100 are required to cover the tip portions 651 of the numerous reinforcing bar groups 65. Moreover, since the same protective cap 100 can be used repeatedly over and over, construction costs can be further reduced.
[0024]
4 to 6 show other embodiments of the protective cap according to the present invention. In the protective cap illustrated in FIG. 4, the closing portion 91 is formed integrally with the cavity portion 90.
[0025]
In the protective cap illustrated in FIG. 5, the shape of the closure 91 is flat. In the protective cap shown in FIG. 6 in which the closing portion 91 and the hollow portion 90 are separate members and are connected to each other by an adhesive or the like, the shape of the closing portion 91 is flat, and the closing portion 91 is hollow. The unit 90 is integrally formed.
[0026]
7-13 is a figure which shows the septic tank installation method based on this invention. First, as shown in FIG. 7, a concrete substrate 63 is installed at the bottom of a hole 50 excavated in the ground. The concrete board 63 is provided with a necessary number of reinforcing bar groups 65. The size and shape of the concrete substrate 63 must be large enough to support the septic tank that is part of the septic device.
[0027]
The reinforcing bar group 65 includes an arbitrary number, for example, three reinforcing bars, and tip portions 651 to 653 extend from one surface of the concrete substrate 63 in the direction of the ground surface GL and protrude from the ground surface GL.
[0028]
The reinforcing bar group 65 is covered with a concrete member 60 such as a fume pipe, for example, and a tip end portion 651 protrudes from the concrete member 60 to the outside. The protrusion amount is selected so as to be, for example, a length of 40 cm or more in order to connect with a transverse line to be attached later. The concrete member 60 may be formed as a cylinder or a wall. The reinforcing bar group 65 is constrained by loop bars 66 that are coupled to each other in the vertical direction.
[0029]
Next, as shown in FIG. 8, the protective cap 100 is put on the tip portion 651 of the set of the reinforcing bar group 65 so as to cover it. The protective cap 100 has been described with reference to FIGS. 1 to 4 and, therefore, further description is omitted here.
[0030]
Next, as shown in FIG. 9, the septic tank 10 is installed in the hole 50. More specifically, the septic tank 10 is placed on the concrete substrate 63. The lid 81 of the septic tank 10 is almost the same height as the ground surface GL. Further, although not shown, the septic tank 10 may be fixed to the concrete substrate 63. The illustrated septic tank 10 may be any currently known and proposed in the future.
[0031]
Next, as shown in FIG. 10, the periphery of the septic tank 10 is backfilled so that the lid 81 of the septic tank 10 is on the ground surface GL. Further, the protective cap 100 is temporarily removed, and the ready-mixed concrete 30 is injected into the concrete member 60 made of a fume pipe or the like using the funnel-shaped injection member 45. After the concrete member 60 is filled with the ready-mixed concrete 30 until the slab is released, the protective cap 100 is again put on the front end portion 651 of the reinforcing bar group 65.
[0032]
Next, as shown in FIGS. 11 and 12, the distal end portion 651 of the set of the reinforcing bar group 65 is bent and connected to the transverse bar 200 provided on the septic tank 10.
[0033]
Thereafter, as shown in FIG. 13, the ready-mixed concrete 30 is placed around the lids 81, 82 and 83 of the septic tank 10 to form an upper concrete slab 300. Thereby, even if the vehicle is parked on the purification device, the purification device can be protected from the vehicle load.
According to the purification device installation method described above, the tip portion 651 of the reinforcing bar group 65 is attached to the protective cap 100 through all the steps from the installation of the purification tank 10 to the hole 50, which is the main process, to the backfilling of the hole 50. Therefore, the safety of workers engaged in the septic tank installation work can be ensured. Further, the time and cost required for installing the purification device can be reduced.
