For example, when the wiring / piping material is arranged along the wall surface, the protective cover for accommodating and protecting the wiring / piping material inside is the said as shown in FIGS. 4 and 8 of Patent Document 1. It is composed of a base fixed to the wall surface and a lid body covered with the base, and the base is fixed to the wall surface using screws. For this reason, a plurality of fixed pilot holes for inserting screws are formed in the base, but in many cases, only one is actually used in order to improve work efficiency. If two fixed pilot holes are used, the position of the fixed body with respect to the surface to be fixed is theoretically determined.

Therefore, as described above, if the fixing base of only one of the plurality of fixed pilot holes is fixed with screws and the remaining fixed pilot holes are left as they are, the supervision of construction work other than the operator himself / herself. Authorized construction owners, construction supervisors within the contractor, or other collaborators of the construction (hereinafter referred to as "construction personnel") may recognize that they have forgotten to fix the screws. , The recognition is a misunderstanding for the worker himself, and may cause a problem between the two.

4 and 8 of JP-A-2002-58138

The first problem of the present invention is that when there is a fixed pilot hole that remains without being fixed with screws, the existence of the fixed pilot hole is based on the intention of the worker himself / herself. The second problem is to inform the worker, even if the fixed body is fixed to the fixed surface while the fixing pilot hole is closed by the closing member due to an operator's error, the fixed body is not removed. The purpose is to allow the closed fixed pilot hole to be easily opened.

The invention of claim 1 for solving the above-mentioned problems is a fixed body provided with a fixing base which is fixed to a fixed surface by passing a fixing pilot hole and driving a screw from the front side.
A plurality of the fixing pilot holes are provided, and the fixing base can be fixed to the surface to be fixed by a plurality of screws.
At least one of the plurality of fixed pilot holes is closed by a closing member connected to the fixed pilot hole by a breakable connecting portion.

According to the invention of claim 1, among the plurality of fixed pilot holes provided for fixing the fixed body to the surface to be fixed, one or more fixed pilot holes that are usually used are the ordinary fixed pilot holes. The remaining fixed pilot holes that remain open and are not used are closed by the closing member, and the fixed body is screw-fixed to the fixed surface using only the opened fixed pilot holes. In the state where the fixed body is fixed with screws, the fixed pilot holes that are not used for fixing the screws are closed by the closing member. It turned out that it was not used by the worker himself and he did not forget to fix it by mistake, and there was a misunderstanding between the worker himself and other construction personnel regarding the fixed pilot hole that was not fixed with screws. It will not occur.

In addition, for example, when it becomes necessary to use a fixing pilot hole that is closed by a closing member due to circumstances such as increasing the fixing strength of the fixed body to the surface to be fixed, before fixing the fixed body, The blocking member may be removed with a tool.

On the other hand, if you forget to open the solid pilot hole closed by the closing member, and after fixing the fixed body to the surface to be fixed, if you notice the forgetting or misunderstanding, the closing member that closes the fixing pilot hole. the tool engagement recess in a state that is engaged, by tilting the tool, when the closure member Ru is broken, and the tip of the tool tilting state and allowed to tilt integrally state with the tool The closing member enters the space of the fixed pilot hole provided on the back surface side of the closing member before fracture, and the tilted tool and the broken fragment integrated with the tool are removed to the front side of the fixed pilot hole. The fixed pilot hole closed by the closing member can be opened without removing the fixed body from the fixed surface.

The invention of claim 2 is a fixed body provided with a fixing base that is fixed to a fixed surface by passing a fixing pilot hole and driving a screw from the front side.
A plurality of the fixing pilot holes are provided, and the fixing base can be fixed to the surface to be fixed by a plurality of screws.

A locking portion that can lock a tool such as a screwdriver is formed on the front surface of the closing member, and a striking force that enters the space of the fixed pilot hole between the back surface of the closing member and the fixed surface. It is characterized in that the connecting portion is broken by adding the above, and the closing member punched out on the fixed surface side can be taken out to the front side.

According to the second aspect of the present invention, in a state where the fixed body is fixed to the surface to be fixed , a striking force is applied to the closing member to break the connecting portion of the closing member with the fixing base, and the broken piece is formed. Even if it enters the space of the fixed pilot hole, the fixed pilot hole closed by the closing member can be opened by taking out the broken piece to the front side by using, for example, another special tool.

The invention of claim 3 is characterized in that, in the invention of claim 1 or 2, all of the fixed pilot holes are closed by the closing member.

According to the invention of claim 3, in the state where the fixed body is fixed to the surface to be fixed, all the fixing pilot holes that are not used for fixing the screws are closed by the closing member, so that the fixing pilot holes Since the workers themselves and other construction personnel agree on the number of uses and the position of use, there is no misunderstanding about the part related to the screw fixing of the fixed body.

According to the present invention, in a state where the fixed body is fixed with screws, the fixing pilot holes that are not used for fixing the screws are closed by the closing member. It was found that the pilot hole was not used by the worker himself and was not forgotten to be fixed due to an error, and regarding the fixed pilot hole that was not fixed with screws, the worker himself and other construction personnel There will be no misunderstanding between them.

Further, according to the present invention, if the fixing pilot hole closed by the closing member is forgotten and the fixed body is fixed to the fixed surface and then the forgotten or misunderstood is noticed, the fixing pilot hole is found. in a state in which is engaged a tool in the locking recess of the closing member for closing the, and have it tilts the tool, or by adding a striking force to the closure member, by breaking the closing member, the broken fragments By removing it to the front side of the fixed pilot hole, it is possible to open the fixed pilot hole closed by the closing member without removing the fixed body with respect to the surface to be fixed.

It is sectional drawing which shows the opening order of. It is a top view of the _{base V 0} formed in the state that only a pair of fixed pilot holes H along one diagonal direction are opened.

Hereinafter, the present invention will be described in more detail with reference to examples. In the examples shown in FIGS. 1 to 7, the present invention is carried out on a base V _{0 constituting an attached protective cover C 0 that accommodates and protects a bent portion Pa of the pipe body P.} Accessory protective cover C ₀ is a base V ₀ which is fixed to the wall Wa of the building wall W, consists lid L ₀ Metropolitan is covering on the base V _0, the base V ₀ and the lid L ₀ Are all made of resin. The base V ₀ has a pipe insertion hole 2 for inserting the pipe P drawn from the wall through hole 51 of the building wall W in one portion of the rectangular base plate 1 divided in the longitudinal direction. It is formed, on the other hand part of the width for positioning the width direction of the base V ₁ of the plurality of straight protective cover C ₁ having different sizes with respect to the base V ₀ which comes protective cover C ₀ A plurality of different second to fourth notch holes G _{2 to} G ₄ are continuously formed, and the widest second notch hole G ₂ is covered with the maximum size straight protective cover C ₁ . A first notch hole G ₁ capable of accommodating the body L ₁ is formed by opening along the connection direction of the straight protective cover C _1.

A straight vertical wall portion 3 is formed except for a portion that interferes with the arrangement portion of the pipe body P around the pipe body insertion hole 2 of the base plate 1. That is, the vertical wall portion 3 is along the pair of first straight vertical wall portions 3a along the direction of the long side of the base plate 1 and the short side of the base plate 1, and is also a pair of first straight shapes. It is composed of a second straight vertical wall portion 3b connected to one end portion of the vertical wall portion 3a in the longitudinal direction. Each of the first and second vertical wall portion 3a, the intersection of 3b inside and, of the first to fourth side each notched hole G ₁ ~G ₄ is formed of a pair of first straight vertical wall 3a A total of four portions, including the inside of the end portion, are formed to have the same wall thickness as the standing wall portion 3 to form a fixed base portion 4. Total of four respective fixed base 4 is substantially disposed in the portion of intersection of the sides of the rectangle, each fixed base 4, along the arrangement direction Q of the straight protective cover C ₁ (see FIGS. 1 and 5) Each of the fixed pilot holes H having a long hole shape is formed.

The front side of the four elongated fixed prepared holes H are all closed by the closing plate portion S having the same shape as the fixed prepared holes H. The closing plate portion S has a wall thickness at which a long groove-shaped tool locking groove 11 into which the tip portion of the flat-blade screwdriver T _{1 can be inserted can be formed in the central portion in the width direction, and the fixing pilot hole H} The inner peripheral surface of the block plate portion S and the closing plate portion S are connected by a thin-walled connecting portion 12 over the entire circumference so as to be broken by the _{flat-blade screwdriver T 1, and three locations along the circumferential direction of the closing plate portion S are formed.} , It is a connection reinforcement portion 13 that is partially thicker than the other parts. A total of three connecting reinforcing portions 13 are dispersedly arranged on both sides of the tool locking groove 11. In FIG. 2C, reference numeral 14 denotes a thin portion at the bottom of the tool locking groove 11.

In this embodiment, since all of the four fixed pilot holes H are closed by the closing plate portion S, among the total of four fixed pilot holes H, the worker himself / herself has the intention of the wall surface Wa. Only the fixing pilot hole H required for fixing the base V _{0 is opened. For example, when it is determined that the base V 0} can be fixed to the wall surface Wa by driving the screw B into the two fixing pilot holes H along one diagonal direction, as shown in FIG. By inserting the tip of the flat-blade screwdriver T ₁ into the tool locking groove 11 of the closing plate portion S and applying an impact, the closing plate portion S is broken at the thin-walled connecting portion 12, and the fixed pilot hole H Can be opened. The closing plate portion S can be broken by applying a striking force with the _{flat-blade screwdriver T 1} inserted into the fixed pilot hole H from the back surface side of the _{base V 0.}

_{Next, as shown in FIGS. 4 and 5, the base V 0} is driven by driving the screw B into the wall surface Wa by passing through two fixed pilot holes H opened along one diagonal direction. Is fixed to the wall surface Wa, the fixing pilot hole H that is not used for fixing the screw remains closed by the closing plate portion S. Therefore, the operator can sufficiently fix the _{base V 0 to} the wall surface Wa by using two fixed pilot holes H along the diagonal direction of one of the four fixed pilot holes H in total. I thought that there was, that is, it was not necessary to fix the screws in the remaining two fixing pilot holes H related to non-use, and the worker forgot to fix the screws to other construction personnel. It can be clearly shown on the outside that it is not. For this reason, _{regarding the number of screws required for fixing the screws of the base V 0} , misunderstandings do not occur between the worker himself and other construction workers, and the occurrence of minor disputes can be prevented. Construction can be done smoothly.

In the above example, out of a total of four fixed pilot holes H, two fixed pilot holes H along one diagonal direction are opened and fixed with screws, but only one fixed pilot hole H is used. When using the remaining three fixed pilot holes H except for one specific fixed pilot hole H, or when using all the fixed pilot holes H, in exactly the same manner. Only the closing plate portion S of the necessary fixing pilot hole H may be broken and used. When the specific fixed pilot hole H is not used, the presence of the block plate portion S makes it possible to visually inform other construction personnel that the non-use is the intention of the worker himself / herself. ..

In this construction example, as shown in FIG. 5, _{after the base V 0} is fixed to the wall surface Wa with screws, the base V 0 is directly formed in the second notch hole G _{2 of the base V 0.} With the tip of the base V ₁ of the protective cover C ₁ inserted and the linear protective cover C ₁ base V ₁ positioned in the width direction with respect to the base V _{0 of the attached protective cover C 0,} The base V ₁ is fixed to the wall surface Wa with screws. After that, the pipe body P pulled out from the back of the wall is piped on the bases V ₀ and V ₁ , and the lid L ₁ is covered with the base V _{1 of the straight protective cover C 1. When the lid L 0} is covered with respect to the base V ₀ of the attached protective cover C ₀ , the bent portion Pa and the straight portion Pb of the pipe _{body P are covered with the attached protective cover C 0} and the straight protective cover C, respectively. Contained and protected in _1.

On the other hand, due to the operator's forgetfulness or misunderstanding, a screw B is driven into the fixed prepared hole H opened by breaking the closing plate portion S of the specific fixed prepared hole H, and the base V ₀ is mounted on the wall surface Wa. After fixing to, it may be necessary to drive a screw B into another fixing pilot hole H that is closed by the closing plate portion S. For example, in the example shown in FIG. 6, originally, the base V ₀ was planned to be screw-fixed to the wall surface Wa by using two fixing pilot holes H along one diagonal direction, but it was misunderstood. Of the two fixed pilot holes H that are the targets of the breakage of the closing plate portion S, only one of the closing plate portions S is broken, and the base V ₀ is placed on the wall surface Wa with only one screw. This is the case when it is fixed at B.

In the above case, as shown in FIGS. 6 and 7 (a) to 7 (c), the base V ₀ remains fixed without being removed from the wall surface Wa, as shown in FIG. 7 (a). _{, The tip of the flat-blade screwdriver T 1} that is always available to the operator involved in piping is inserted into the tool locking groove 11 of the closing plate portion S of the fixed pilot hole H to be broken, and the bottom of the tool insertion groove 11 is inserted. _{By breaking through the thin portion 14 of the screwdriver T 1} and press-fitting it into the tool locking groove 11, the tip portion of the driver T 1 is locked to the closing plate portion S. In this state, as shown in FIG. 7B _{, by tilting the driver T 1} in a predetermined direction, the thin-walled connecting portion 12 is broken and fixed during or after the breaking. The fragment S'of the closing plate portion S, which is separated from the inner peripheral surface _{of the prepared hole H and is locked to the tip of the driver T 1} , is scooped up and taken out from the inside of the fixed prepared hole H [Fig. 7 (c)]. In FIG. 7, 14'indicates a fragment of the thin-walled portion 14. Therefore, a thin connection section 12 which connects the closure plate portion S on the inner peripheral surface of the fixed lower hole H, the relationship between the bottom of the thin portion 14 of the tool engagement groove 11, the driver T ₁ of the distal portion It is desirable that the thin-walled connecting portion 12 keeps the connected state and is not broken while breaking through the thin-walled portion 14 at the bottom of the tool locking groove 11. After that, while the base V ₀ is fixed to the wall surface Wa, the screw B is driven into the opened fixed pilot hole H so that the base V ₀ can be placed on the wall surface Wa at two points along one diagonal direction. It is fixed with screws.

Therefore, the tool locking groove 11 of the closing plate portion S can be formed in the shape of a locking hole by penetrating the bottom portion thereof. To break the blocking plate portion S and remove the fractured fragment S'from the fixed pilot hole H, _{simply insert the tip of the driver T 1} into the tool locking groove 11 and lock it. This method may be used when the closing plate portion S can be broken and the broken piece S'can be taken out by tilting the _{driver T 1} without breaking through the thin portion 14. ..

Further, while the base V ₀ is fixed to the wall surface Wa, the closing plate portion S of the unopened fixed pilot hole H is broken and taken out to the front side. Although the extraction of the front side of the fragment S 'shows an example in which a flathead screwdriver T ₁ is the same tool, for fixing under the hole H is small (narrow), the screwdriver T _1, the closing plate part S rupture and, may not perform the two different operations and extraction of the broken piece S ', further, there may be a case where the worker has not bring screwdriver T _1.

When the operator _{brings only a brass screwdriver T 2} , as shown in FIG. 8, a Phillips screwdriver T ₂ for breaking the blocking plate portion S and a piercing tool for taking out the broken piece S' Perform in combination with T _3. First, as shown in FIGS. 8A and 8B, _{the tip of the Phillips screwdriver T 2} brought by the operator is inserted into the tool locking groove 12 of the closing plate portion S to apply a striking force. By adding, the closing plate portion S is broken at the portion of the thin-walled connecting portion 11, and then, as shown in FIGS. 8 (c) and 8 (d), a drill-shaped piercing tool T _{3 having a sharp tip.} By piercing the meat portion of the fragment S'and pulling it toward the front side as it is, the fragment S'can be reliably taken out.

Further, in the embodiment described above, all of the total of four fixed lower hole H of the base V ₀ is molded in a state of being closed by the closing plate part S, screw fixing of the base V ₀ against the wall Wa At least one fixed pilot hole H is required, and two fixed pilot holes H are required to determine the arrangement position of the _{base V 0 with respect to the wall surface Wa.} Therefore, as shown in FIG. 9, two fixed pilot holes H along the diagonal direction of one of the four fixed pilot holes H arranged at the intersections of the respective sides of the rectangle are opened as they are. The remaining two fixed pilot holes H along the other diagonal direction are formed in a form of being closed by the closing plate portion S, thereby eliminating the need for the closing plate portion S to break and not being used. The fixed pilot hole H of the above can be closed by the closing plate portion S.

Further, in the above embodiment, as an example of the fixed body to be screw-fixed to the fixed surface, the base V _{0 of the attached protective cover C 0} of the pipe body is mentioned, but the screw is fixed to the fixed surface. Therefore, there are many fixed bodies in which a plurality of fixed pilot holes are formed in advance, and the present invention can be applied to any fixed body fixed to the surface to be fixed by screw fixing.

Further, since the base V _{0 of the attached protective cover C 0} in which the unused fixed pilot hole H exists is completely covered by the lid L ₀ , the unused fixed pilot hole H has a structure that is not exposed. Although it is a fixed body, in the fixed body having a structure in which the unused fixed pilot hole H is exposed in the used state of the fixed body, the unused fixed pilot hole H covered with the closing plate portion S is not applicable. There is an advantage that other construction personnel can visually recognize that the use is based on the intention of the worker himself / herself while using the fixed body.
