Description

  The present invention relates to a shielding plate installation structure for a construction site installed between a construction site and a sidewalk.

  Generally, during various construction works, a shielding plate is installed between the construction site and the sidewalk for the beauty of the city and the safety of pedestrians. Such a shielding plate is also constructed in an assembling manner so that installation costs can be reduced and reused.

  FIG. 1 shows a shield at a construction site that has been used so far. The H beam 100 is fixed vertically with an appropriate distance from the ground. A plurality of scaffolding bars 102 are connected to the H beam 100 in the lateral direction. In the panel 112, a locking recess 104 and a locking protrusion 106 are formed in front of the scaffolding rod 102 and in front portions on both sides of the front surface portion 103, respectively, as shown in FIG. 2. Further, the panel 112 is provided with support pieces 108 and 110 that are bent inwardly of the panel behind the locking recess and the locking protrusion, respectively. Such a plurality of panels 112 are assembled to each other in the lateral direction, and each is assembled to the scaffold bar 102. The upper and lower engagement pieces 118 and 120 of the clamp 116 as shown in FIG. 3 engage with the support pieces 108 and 110 of the left and right panels 112. In this state, the clamp 116 is retracted by tightening the tightening bolt 122, whereby the panel 112 is tightly fixed to the scaffold bar 102.

  However, each panel 112 used is formed by bending a metal plate having a thickness of about 0.5 to 1.2 mm in order to reduce manufacturing costs and reduce weight. The locking recess 104, the locking projection 106, and the support pieces 108 and 110 are bent on both sides of the front surface portion 103 without any reinforcement. Therefore, the front surface portion 103 of the panel 112 is very weak against warping and impact, and is easily deformed even during weak construction or after construction. Therefore, since the lifetime is very short and the reuse rate is low, the burden of the purchase cost increases accordingly.

  Further, the left and right panels 112 are combined with each other by a locking concave portion 104 and a locking convex portion 106 that are exposed at the front portions of the left and right sides. Therefore, when the clamp 116 is clamped, each panel 112 is simply brought into close contact with the scaffolding rod 102, and no pulling force or binding force is given between the panels, and a gap is generated between them. Therefore, not only the appearance is not beautiful, but there is a risk of misunderstanding of hand-cutting construction. Also, when some of the clamps are released due to strong winds or strong impacts, the panel protrudes from the adjacent panel to the sidewalk and is completely separated, leading directly to an accident due to inadequate safety measures. .

  In particular, each clamp 116 that clamps and fixes each panel 112 is fixed so that the body to which the scaffolding rod 102 is assembled and the engagement pieces 118 and 120 that are hooked on the panel 112 are perpendicular to each other. As shown in FIG. 4, also when installing on the inclined surface 124 where the ground is inclined, the scaffold bar 102 for assembling the clamp is perpendicular to the support pieces 108, 110 of the panel 112 regardless of the inclination angle of the ground. Clamping with the clamp 116 can be performed only by fixing as it is made. Therefore, the required number of scaffolding bars 102 increases, and a lot of manpower and time are required during the installation work of the shielding plate. This causes many problems such as an increase in construction costs.

  An object of the present invention is to provide a shield plate installation structure at a construction site that enables the following. The strength of the panel can be improved compared to the thickness of the plate material used. In addition, when the panels are clamped and held by the clamp, the left and right panels can be brought into close contact with each other. Even if some clamps lose their original function, there is no possibility that some panels will protrude forward due to the firm coupling force between the left and right panels. it can. In addition, when installing on an inclined surface, even if the scaffold bar has the same inclination angle as the inclined surface, the panel can be firmly tightened and held by the clamp, so the necessary number of scaffold bars can be reduced.

  The object of the present invention is achieved by a shielding plate installation structure at a construction site configured as follows. At least one reinforcing rib is formed on the front surface of the panel. In the center part of the left and right side parts, an assembling concave part and an assembling convex part that are inclined forward one side are formed so that mutual assembling is performed between the panels from the left and right directions. . The clamp allows the coupling piece for coupling and supporting the rotating piece to rotate with respect to the body to which the scaffold bar is assembled, so that the clamp can be held even when the scaffold bar is inclined with respect to the panel.

  Since each panel 20 used in the present invention has its strength reinforced by the reinforcing ribs 22 provided on the front surface portion thereof, the service life can be extended, so that the construction cost can be reduced accordingly.

  In addition, the left and right panels 20 are inclined with respect to the left and right directions by the assembling concave portions 23 and the assembling convex portions 24 formed so as to be inclined and extend with respect to the left and right directions at the center portions of the left and right side surfaces, respectively. And assembled. By doing so, the left and right panels 20 are more closely adhered to each other by the guide of the inclined surfaces 27 and 28 provided in the assembling concave portion 23 and the assembling convex portion 24 at the time of tightening and holding using the clamp 30. Is done. Therefore, there is no possibility that a gap is generated between the left and right panels 20, and a smooth and neat appearance can be maintained. Further, even when the tightening and holding function of some clamps 30 is lost due to strong winds or strong impacts, the panel is separated forward by the assembly of the assembly recesses 23 and the assembly projections 24. There is no fear of being done. Therefore, a firm assembly force between the left and right panels can be maintained, and the risk of an accident due to inadequate safety measures can be eliminated by separating the panels after construction.

  Further, the upper and lower engaging pieces 35 of the clamp 30 that clamps and fixes the panel 20 to the scaffolding rod 12 are connected to the body 31 by the shaft pin 33. Even when the scaffolding bar 12 does not form a right angle with the panel 20, the clamp 20 can be clamped and held by the clamp 30. Thereby, when installing on the inclined surface, if the scaffolding bar 12 is fixedly installed so as to have the same inclination angle as the inclined surface, the necessary number of scaffolding bars 12 can be reduced. Therefore, not only can the time and manpower during construction be saved, but there are many effects such as saving construction costs.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, in the drawings, the same components are denoted by the same reference numerals as much as possible, and specific descriptions of related known techniques and functions are omitted to avoid obscuring the gist of the present invention. I will decide.

  FIG. 5 is a perspective view of a main part of the present invention. In the present invention, a plurality of scaffolding rods 12 are arranged on the H beam 10 that is vertically fixed at an appropriate interval between the construction site and the sidewalk so that the plurality of scaffolding bars 12 have an appropriate interval in the vertical direction. Connected and fixed in the direction. In front of the scaffolding rod 12, a plurality of panels 20 bent with a metal plate are arranged side by side and joined together. And each using the some clamp 30 assembled | attached to the scaffolding rod 12, each of these is comprised so that the left and right panels 20 which adjoin may be clamp-fixed simultaneously.

  The H beam 10 and the scaffold bar 12 used in the present invention are general ones that are often used during construction work. A plurality of H beams 10 are fixed vertically to the ground so as to surround the construction site. In addition, the scaffold bar 12 is connected and fixed in the horizontal direction between the H beams 10 so as to maintain an appropriate vertical distance.

  8 to 10 show a panel used in the present invention. The panel 20 generally has a narrow left and right width and is vertically long, and one or more reinforcing ribs 22 are formed vertically on the front surface portion 21 thereof. In the central part of the left and right side parts bent from the front part 21, an assembling recess 23 and an assembling protrusion each extend obliquely with respect to the left-right direction for coupling between adjacent panels 20. 24 is formed. In addition, support pieces 25 and 26 that are bent forward and engaged with the clamp 30 are formed at the rear ends of the left and right side portions.

  Furthermore, the assembly recess 23 and the assembly projection 24 provided on both sides of the panel 20 are for male-female coupling. If the assembly convex portion 24 is assembled with a margin, the assembly concave portion 23 is more deeply and safely coupled by the guide of the inclined surfaces 27 and 28 when clamped by the clamp 30. In addition, close contact between the left and right panels 20 is possible.

  11 and 12 show a clamp used in the present invention. In the clamp 30 that clamps and fixes each panel 20 to the scaffolding rod 12, a fastening bolt 32 is screwed to the rear of the U-shaped body 31 to which the scaffolding rod 12 is assembled. A connecting piece 34 is rotatably connected to the upper and lower ends of the body via shaft pins 33. A pair of engaging pieces 35 are connected to the connecting pieces 34 so as to be rotatable by pins 36, respectively.

In the present invention, as in the prior art, a plurality of H beams 10 are fixed vertically at appropriate intervals at the boundary between the construction site and the sidewalk. The scaffolding rods 12 are connected and fixed in the lateral direction so as to have an appropriate space in the vertical direction between the H beams 10. In addition, a plurality of standardized panels 20 are coupled to the front of the scaffold bar 12 on the left and right. Then, the fastening bolts 32 are tightened with the upper and lower engaging pieces 35 of the clamps 30 that are respectively coupled to the scaffolding bars 12 engaged with the supporting pieces 25 and 26 of the adjacent left and right panels 20. Then, the clamp 30 is retracted from the scaffold bar 12. Then, each panel 20 is closely fixed to the scaffolding rod 12 to form the shielding plate A.

  Here, each panel 20 has at least one or more reinforcing ribs 22 formed at the front surface portion 21 so that the bending force and strength are much stronger than the thickness of the plate material used when the panel 20 is manufactured. Will have. Therefore, it is easy to handle and is less likely to be deformed by an external impact, and the service life can be extended.

  Further, the assembly recess 23 and the assembly projection 24 which are the coupling means of each panel 20 are formed at the center of the left and right side surfaces, and are coupled in the left-right direction. For this reason, after the left and right panels 20 are assembled together, even when some clamps 30 cannot perform their original functions when the clamps 30 are fixed by the clamps 30, the panels are affected by the bonding force with other adjacent panels. There is no fear of being separated forward, and the original function can be achieved.

  Furthermore, the assembly recesses 23 and the assembly projections 24 provided on the left and right side portions of each panel 20 are formed so as to extend while being inclined with respect to the left-right direction. The more the pulling force is applied at the time of clamping and holding using the clamp 30, the deeper the assembling convex part 24 is coupled to the assembling concave part 23, and the complete coupling can be achieved. At this time, the left and right panels 20 are subjected to a tensile force between the inclined surfaces 27 and 28 of the assembly concave portion 23 and the assembly convex portion 24. Therefore, there is no possibility that a gap is generated between the left and right panels 20. Therefore, there is a sense of stability and a solid construction is possible.

  In addition, when installing on an inclined surface where the ground is inclined, as shown in FIG. 13, the scaffolding rod 12 connected and fixed to the H beam 10 is connected to the ground regardless of the inclination angle with the panel 20. The H beam 10 is connected and fixed so as to have the same inclination angle. And the clamp 30 is assembled | attached in the point which meets the support pieces 25 and 26 of the left-right panel 20. FIG. Regardless of the inclination angle of the body 31 of the clamp 30, the connecting piece 34 that connects the engaging piece 35 from the body 31 is rotated about the shaft pin 33, and the engaging portion of the engaging piece 35 is The panel 20 is perpendicular to the support pieces 25 and 26 of the panel 20. In this state, after engaging with the support pieces 25 and 26 and then tightening the tightening bolt 32, each panel 20 is tightly fixed to the scaffold bar 12 by the clamp 30 and clamped. The Therefore, the installation time, manpower, and cost of the shielding plate A can be reduced by the amount that can reduce the required number of scaffolding bars 12.
