Description

Technical Field

[0001] The present invention relates to a protective cover that forms a running surface by covering protected members such as pipes provided at a construction site.

Background Art

[0002] At a construction site of a building, pipes may be temporarily installed on the floor surface of the building or the road surface around the building, and a work cart or worker may travel in a direction crossing these temporary members. In this case, in order to run a work cart or the like, a protective cover is arranged so as to straddle the temporary members in order to protect the temporary members such as pipes as protected members. Examples of the pipes include electric wire pipes such as electric wire cables and fluid guide pipes that guide liquids or air, etc., and these are removed after the construction is completed. Also, at a construction site of a building, a work cart or worker may travel in a direction crossing an attached member such as a door rail that is already attached to the building to guide a door and constitutes a part of the building. In this case, in order to run a work cart or the like, a protective cover for protecting the attached member as a protected member is arranged so as to straddle the attached member.

[0003] A protective cover for protecting pipes such as electric wires, which are temporary members, is described in Patent Document 1.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The protective cover described in Patent Document 1 has a base that forms a storage chamber for accommodating pipes, two inclined plates arranged on both sides of the base, and an opening / closing plate arranged between the inclined plates to cover the storage chamber. This protective cover uses the pipes as a protected member and is used to protect them. A traveling bogie or the like can travel without stepping on the pipes due to the protective cover.

[0006] However, this protective cover cannot protect attachment members such as door rails that are already attached to a building, that is, construction parts that are constructed as part of the building. This is because the attachment members cannot be positioned on the base for accommodating the pipes. Therefore, the protective cover described in Patent Document 1 cannot be used as a protective cover for protecting attachment members in the area for crossing attachment members such as door rails.

[0007] An object of the present invention is to provide a protective cover that protects both temporary members and attachment members at a construction site of a building and guides the travel of a traveling bogie or the like.

Means for Solving the Problem

[0008] The present invention relates to a protective cover that is disposed across the upper part of a member to be protected and forms a running surface, and includes a top plate that extends along the member to be protected and covers the member to be protected, a first side plate provided on one side of the top plate and in contact with the floor surface, and a second side plate provided on the other side of the top plate and in contact with the floor surface. A cover body, a first inclined plate that is connected to the first side plate and disposed on the floor surface, and a second inclined plate that is connected to the second side plate and disposed on the floor surface, and the running surface is formed by the top plate and the first inclined plate. A second inclined plate, a mounting member for mounting the first inclined plate and the second inclined plate on the floor surface, a first support plate extending along the inner side of the first side plate, a second support plate extending along the inner side of the second side plate, and a bottom plate integrated with the first support plate and the second support plate. And a storage tray detachably disposed inside the cover body, and the storage space formed by the storage tray and the cover body houses a member to be protected made of a temporary member and covers it with the top plate, and the storage tray is removed to cover the member to be protected made of an attached member with the top plate of the cover body.

Effects of the Invention

[0009] This protective cover is used to protect temporary members such as pipes used for construction when a work cart is run in a direction crossing the temporary members during building construction. When a work cart or the like is run in a direction crossing an attached member such as a door rail constituting a building, the protective cover is used to protect the attached member. Thus, the protective cover can selectively protect either the temporary member or the attached member as a member to be protected and guide the running of a running cart or the like.

Mode for Carrying Out the Invention

[0011] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a state where a protective cover 10 is arranged on the floor surface F of a building, that is, on a construction work surface, and FIG. 2 is an exploded perspective view of the protective cover 10. The protective cover 10 is arranged on the floor surface F in order to allow a work cart or a worker to travel at a construction site of a building. Piping P is arranged as a temporary member on the floor surface F shown in FIG. 1. In order to protect the temporary member as the member to be protected arranged in this way, the protective cover 10 is arranged on the floor surface F so as to straddle the member to be protected. When the construction of the building is completed, the protective cover 10 is removed from the floor surface F. The piping P is a member in which an electric wire cable is housed inside a protective tube, and is used to supply power to electric equipment used when constructing a building. When the construction of the building is completed, the piping P is removed.

[0012] The protective cover 10 has two inclined plates 11 and 12, a first inclined plate 11 and a second inclined plate 12, and a cover body 13 arranged between these inclined plates 11 and 12. A traveling surface on which a work cart or the like travels is formed by the surfaces of the respective inclined plates 11 and 12 and the surface of the top plate 14. The inclined plates 11 and 12 and the cover body 13 are made of metal, and as the inclined plates 11 and 12, as shown by partially dotting in FIG. 1, a non-slip iron plate is used. The non-slip iron plate is also called a checker plate or a striped steel plate.

[0013] As shown in Fig. 2, the cover body 13 includes a top plate 14 that extends along a protected member composed of pipes P and covers the pipes P, a first side plate 15 integrally provided on one side in the width direction of the top plate 14, and a second side plate 16 integrally provided on the other side of the top plate 14. Each of the side plates 15 and 16 extends in the vertical direction substantially perpendicular to the horizontal top plate 14, and the lower sides of the side plates 15 and 16 abut against and contact the floor surface F. Notch portions 17 are provided at both longitudinal ends of each of the side plates 15 and 16. Since the notch portions 17 are provided, the length in the direction along the top plate 14 in the lower portions of the side plates 15 and 16 is set shorter than the top plate 14.

[0014] The two inclined plates 11 and 12 have the same shape as each other. If one is the first inclined plate 11, the other is the second inclined plate 12. One inclined plate 11 is arranged on the floor surface F connected to one side plate 15 of the cover body 13, and the other inclined plate 12 is arranged on the floor surface F connected to the other side plate 16. One end portion on the cover body 13 side in the traveling direction of each of the inclined plates 11 and 12 is a stepped end portion 21 having a height substantially corresponding to the vertical height dimension of the side plates 15 and 16, and the other end portion is a contact end portion 22 that contacts the floor surface F. The contact end portion 22 has a predetermined width in the traveling direction.

[0015] Fig. 3 is a partially cutaway plan view of Fig. 1, showing a state in which a part of the inclined plates 11 and 12 and a part of the top plate 14 are cut away. Fig. 4 is a cross-sectional view of the protective cover 10.

[0016] On the inner surfaces, i.e., the lower surfaces, of the respective inclined plates 11 and 12, as shown in FIG. 3, five longitudinal reinforcing plates 23 extending in the traveling direction are welded. Each longitudinal reinforcing plate 23 extends from the stepped end portion 21 on the side of the cover body 13 to near the contact end portion 22 and is substantially triangular. Transverse reinforcing plates 24 extending in a direction crossing each longitudinal reinforcing plate 23 are welded to the inner surfaces of the inclined plates 11 and 12, and each transverse reinforcing plate 24 is positioned between the longitudinal reinforcing plates 23. The longitudinal reinforcing plates 23 and the transverse reinforcing plates 24 are made of metal, and a plurality of longitudinal reinforcing plates 23 and a plurality of transverse reinforcing plates 24 are welded to the inner surfaces of the respective inclined plates 11 and 12 in a lattice pattern, enhancing the strength thereof without increasing the weight of the inclined plates 11 and 12. Further, the inclination angles of the inclined plates 11 and 12 are set by the longitudinal reinforcing plates 23.

[0017] When the direction crossing the longitudinal reinforcing plate 23 is defined as the width direction of the inclined plates 11 and 12, as shown in FIG. 3, a reference sign a is shown in parentheses on the longitudinal reinforcing plate 23 located on the outermost side in the width direction.

[0018] Mounting holes 25 are provided at the contact end portions 22 of the inclined plates 11 and 12, and as shown in FIGS. 4 and 5, a fastening member 26 composed of a set screw, a nail, or the like passes through the mounting hole 25 and is fastened to the floor surface F. Thereby, the inclined plates 11 and 12 are fastened to the floor surface F by the fastening member 26 and installed so as not to move. That is, the fastening member 26 constitutes a mounting member.

[0019] When temporary members such as piping P are arranged across the floor surface F as protected members and the temporary members are to be protected, the piping P as a temporary member is accommodated in the accommodation tray 30. The accommodation tray 30 includes a first support plate 31 extending along the inside of the first side plate 15, a second support plate 32 extending along the inside of the second side plate 16, and a bottom plate 33 integrated with both support plates 31 and 32. The accommodation tray 30 is detachably arranged inside the cover body 13, and temporary members such as piping P are accommodated in the accommodation tray 30. The temporary member is arranged in an accommodation space 34 formed by the accommodation tray 30 and the cover body 13, as shown in FIG. 4.

[0020] At both longitudinal ends of the support plate 31, a first connecting rod 35 is provided protruding outward in the width direction of the storage tray 30. Similarly, at both longitudinal ends of the support plate 32, a second connecting rod 36 is provided protruding outward in the width direction of the storage tray 30. As shown in Fig. 2, mounting holes 37 are formed at the tip ends of the respective connecting rods 35, and mounting holes 37 are also formed in the respective connecting rods 36. Mounting holes 38 are formed in the longitudinal reinforcing plates 23(a) on the outer sides in the width direction provided on the respective inclined plates 11 and 12 corresponding to the mounting holes 38. Nuts 39 are welded to the inner surfaces of the longitudinal reinforcing plates 23(a) corresponding to the mounting holes 38. When bolts 41 are passed through the mounting holes 37 of the respective connecting rods 35 and 36 and the mounting holes 38 provided in the longitudinal reinforcing plates 23(a) and screwed to the nuts 39, the two connecting rods 35 are connected to the inclined plate 11, and the two connecting rods 36 are connected to the inclined plate 12. Washers 42 and spring washers 43 are mounted on the bolts 41.

[0021] Thereby, the two inclined plates 11 and 12 are connected to the storage tray 30 by the connecting rods 35 and 36, and due to the weight including the inclined plates 11 and 12 and the storage tray 30, that is, their own weight, the inclined plates 11 and 12 are installed so as not to move on the floor surface F. Therefore, when a temporary member is stored in the storage tray 30, the connecting rods 11 and 12 constitute a mounting member that connects the storage tray 30 to the inclined plates 11 and 12 and mounts it on the floor surface F. Thereby, it is possible to prevent the inclined plates 11 and 12 from moving without attaching a fastening member 26 made of a set screw or the like to the floor surface F. However, the inclined plates 11 and 12 may be connected to the storage tray 30 by the connecting rods 35 and 36, and the fastening member 26 may be attached to the inclined plates 11 and 12 as shown in Fig. 4. In that case, the inclined plates 11 and 12 are installed on the floor surface F by the connecting rods 35 and 36 constituting the mounting members respectively and the fastening member 26.

[0022] The connecting rods 35 and 36 are attached to the vertical reinforcement plate 23(a) by bolts 41, but members provided with mounting surfaces extending in the traveling direction of the inclined plates 11 and 12 may be attached to the respective inclined plates 11 and 12 for connecting the connecting rods 35 and 36. That is, even members other than the vertical reinforcement plate 23(a) can connect the inclined plates 11 and 12 and the storage tray 30. Further, although the bolt 41 is screwed into the nut 39 welded to the vertical reinforcement plate 23(a), if the mounting hole 38 is a threaded hole, the bolt 41 can be screwed into a member such as the vertical reinforcement plate 23(a) without using the nut 39.

[0023] FIG. 5 is a cross-sectional view of the protective cover 10 covering the door rail R as an attached member, and FIG. 6 is a plan view showing the central portion in the traveling direction of the protective cover with the inclined plates 11 and 12 removed in FIG. 5. In FIG. 6, the inclined plates 11 and 12 are shown by a two-dot chain line in a removed state.

[0024] The door rail R in FIG. 6 is attached to a portion partitioning two regions inside the building, and during construction, a work cart or worker may travel in a direction crossing the door rail R as an attached member. In this case, the door rail R as an attached member is covered by the cover body 13 without using the storage tray 30. As shown in FIG. 5, the inclined plates 11 and 12 are arranged on both sides in the traveling direction of the cover body 13. The stepped end portions 21 of the inclined plates 11 and 12 are in contact with the side plates 15 and 16 of the cover body 13 or are continuous with the side plates 15 and 16 with a gap of about several millimeters therebetween.

[0025] When a fastening member 26 such as a set screw is attached to the mounting hole 25 formed at the contact end portion 22 of each of the inclined plates 11 and 12 as shown in FIG. 5, the inclined plates 11 and 12 are installed on the floor surface F by the fastening member 26.

[0026] On the other hand, as shown in FIGS. 5 and 6, mounting holes 38 are formed in the vertical reinforcing plate 23(a), and by using the mounting holes 38, the respective inclined plates 11 and 12 can be connected to the cover body 13 by the first connecting lever 44 and the second connecting lever 45. The connecting levers 44 and 45 have the same shape as each other.

[0027] The connecting lever 44 has a base portion 47 in which a mounting hole 46 is formed, and an engaging portion 48 provided at the tip of the base portion 47 and bent at a right angle with respect to the base portion 47, and has a planar L-shape. When the engaging portion 48 is engaged with the inner surface of the first side plate 15 of the cover body 13 and the connecting lever 44 is connected to the inclined plate 11 by a bolt 41, the inclined plate 11 is fixed to the side plate 15 of the cover body 13. Similarly, the connecting lever 45 has a base portion 47 in which a mounting hole 46 is formed, and an engaging portion 48 provided at the tip of the base portion 47 and bent at a right angle with respect to the base portion 47, and has a planar L-shape. When the engaging portion 48 is engaged with the inner surface of the second side plate 16 of the cover body 13 and the connecting lever 45 is connected to the inclined plate 12 by a bolt 41, the inclined plate 12 is fixed to the side plate 15 of the cover body 13.

[0028] As shown in FIG. 6, the two inclined plates 11 and 12 are connected to the cover body 13 by the connecting levers 44 and 45, and due to the weight including the inclined plates 11 and 12 and the cover body 13, the inclined plates 11 and 12 are installed so as not to move on the floor surface F. Therefore, when covering the attachment member with the cover body 13, the connecting levers 44 and 45 constitute a mounting member that connects the cover body 13 to the inclined plates 11 and 12 and mounts them on the floor surface F. Thereby, even without attaching a fastening member 26 such as a set screw to the floor surface F, the inclined plates 11 and 12 are prevented from moving, but the inclined plates 11 and 12 may be connected to the cover body 13 by the connecting levers 44 and 45, and the fastening member 26 may be attached to the inclined plates 11 and 12 as shown in FIG. 5. In that case, the inclined plates 11 and 12 are installed on the floor surface F by the connecting levers 44 and 45 that constitute the mounting members respectively and the fastening member 26.

[0029] The protective cover 10 is arranged to form a running surface that straddles the upper part of the protected member for the bogie or the runner. As shown in FIG. 4, when constructing a building, the protective cover 10 is used to protect temporary members such as pipes P used for construction when a work cart or the like has to run across the temporary members. That is, the protective cover 10 is used to protect the members used for constructing the building.

[0030] Furthermore, the protective cover 10 is used to protect attached members such as door rails R that form part of the building when a work cart or the like has to run across the attached members during construction work. That is, the protective cover 10 is used to prevent the attached members constructed as the building from being damaged by the construction work and to protect them.

[0031] In this specification, members used for constructing a building and removed after construction are defined as temporary members, and members that form part of the building are defined as attached members. As described above, the protective cover 10 can guide the running of a bogie or the like in the direction across the protected member while protecting both the temporary member and the attached member as the protected member. Therefore, if a large number of protective covers 10 are prepared at a construction site or a civil engineering site, the same type of protective cover can be selectively applied to both the temporary member and the attached member. The floor surface on which the protective cover 10 is arranged is not limited to the floor surface of the building, but means the working area surface of construction work such as a road surface when a work cart or the like runs across the protected member.

[0032] The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist thereof. The temporary member as the protected member may be not only pipes P but also hoses for liquid supply or the like. The attached member as the protected member may be not only door rails R but also crossbars such as thresholds or members protruding from the floor surface.
