Description

  The present invention relates to a scaffolding with improved peelability of building materials containing cement such as ready-mixed concrete and mortar with respect to an aluminum material.

  2. Description of the Related Art Conventionally, as a scaffolding platform, a built-up scaffolding at a construction site or the like and a mobile worktable having a folding pedestal have been widely used. In many cases, an aluminum material is used for a scaffold plate spanned between support frames for a temporary scaffold, a scaffold plate made of a top plate of a movable work table, and the like. In recent years, aluminum materials are often used not only for scaffold plates but also for other components such as pedestals.

  Such a scaffolding is usually often used at a construction site, for example, for work using ready-mixed concrete or mortar.

  Aluminum scaffolds used at construction sites are often leased items, and leasing companies lend a large number of scaffolds to construction companies and the like. However, aluminum has the property that ready-mixed concrete, mortar, etc. are likely to adhere to it, and when leasing contractors lend scaffolding bases to the next customer, they can remove the ready-mixed concrete and mortar from the previous site. I was struggling.

  That is, since the commercial value of a dirty scaffolding platform is reduced for a contractor who leases the scaffolding platform, the removal of the ready-mixed mortar and the mortar is processed with respect to the scaffolding plate to which the ready-mixed mortar and mortar are particularly likely to adhere. However, this naturally increases labor costs. Moreover, even if it is going to remove raw concrete and mortar mechanically using a dedicated machine, the initial cost of introducing the dedicated apparatus becomes a burden. Moreover, even if such an apparatus is used, there is still a possibility that the surface of the scaffold base body may be accidentally scraped off.

  In view of this, the present applicant has proposed a scaffolding base in which a sheet material can be replaced on the surface so that the surface of the scaffolding plate can be maintained beautifully (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 10-018585

  If you change the sheet material, you can maintain a beautiful state, and certainly the product value may not be lost, but it is troublesome to change the sheet material one by one. In particular, since the leasing company handles a large number of scaffolds, both the cost of the sheet material and the labor become a considerable burden.

  This invention discovers that the mortar adhering to the coating surface can be peeled easily, and provides the scaffold which can solve the said subject by forming the coating film of predetermined thickness on the surface of the plate body which consists of aluminum materials. The purpose is that.

  (1) The present invention is a scaffolding platform in which a plurality of parts including a plate body serving as a scaffold are formed of an aluminum material, and a foot coat scene is formed by forming a coating film having a predetermined thickness on at least the surface of the plate body. While protecting, the surface property of the said coating film was densified rather than the surface property of the aluminum material, and the peelability of building materials containing cement, such as ready-mixed concrete and mortar, was improved.

  (2) The present invention is the scaffold according to (1), wherein the plate is formed on a surface of an anodized film formed by anodizing.

  (3) The present invention is characterized in that in the scaffold of (1) or (2), the coating film is formed by electrodeposition coating.

  (4) The present invention is characterized in that in the scaffold according to (1) or (2), the coating film is formed by baking.

  (5) In the scaffold according to any one of (1) to (4), the present invention is characterized in that a melamine resin is included in the coating material forming the coating film.

  According to the present invention, while protecting the surface of the scaffolding made of aluminum material so as not to be damaged, even if raw concrete or mortar adheres, they can be quickly removed, and the peeling effect of kelen is remarkably increased. It becomes possible to maintain the raised state over a long period of time. Therefore, for example, in a leasing company, the maintenance of a large number of owned platform is extremely easy. In particular, the removal work of ready-mixed concrete, mortar, and the like attached to the surface of a plate or the like is facilitated, so that labor can be reduced and labor costs can be reduced according to the labor reduction.

It is explanatory drawing by the planar view of the scaffold board used for the scaffold base which concerns on embodiment. It is explanatory drawing by the front view of the same scaffold board. It is explanatory drawing which shows the modification of a scaffold board. It is explanatory drawing by the front view of the scaffold board used for the scaffold base which concerns on other embodiment.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The scaffold board 1 which concerns on 1st Embodiment shown in FIG.1 and FIG.2 is used for the scaffold stand built as a temporary scaffold around the building in the construction site etc. FIG.

  The scaffold plate 1 includes a plate body 10 made of an aluminum material as a main component, and the plate body 10 has a horizontally long rectangular shape, for example, a thin box shape with an open bottom surface. The both ends in the longitudinal direction of the plate body 10 are engaged with the recumbent pipe 4 that is stretched in a state orthogonal to the vertical pipe 3 in the pipe frame of the temporary scaffold, so that the operator can freely come and go. Or used as a scaffold for work. Hereinafter, the upper surface of the plate 10 of the scaffold board 1 is referred to as a foot scene.

  In a temporary scaffold composed of such a scaffold board 1, work using raw concrete (hereinafter sometimes simply referred to as “green concrete”) or mortar is often performed. For example, an operator works on the scaffold board 1. In some cases, mortar is applied to the walls of buildings.

  In the scaffold board 1 used for such an application, in this embodiment, a coating film 11 having a predetermined thickness is formed on the surface of the plate body 10 of the scaffold board 1 to protect the foot scene, and the surface of the foot scene. The property is densified to enhance the peelability of building materials containing cement such as ready-mixed concrete and mortar.

  That is, a scaffold board 1 using a plate body 10 made of an aluminum material as a scaffold, and a coating film 11 having a predetermined thickness is formed on the surface of the plate body 10 to protect a foot scene, and a coating for forming the foot scene. It is characterized in that the surface properties of the film 11 are made higher in density than the surface properties of the aluminum material.

  Here, the coating film 11 is formed by electrodeposition coating. In addition, as a pre-process of electrodeposition coating, the plate body 10 is anodized, and an anodized film surface is formed on the surface of the plate body 10, and the coated film is formed on the anodized film surface. ing. That is, the coating 10 is formed on the surface of the anodic oxide coating (anodized coating) formed by performing anodizing (alumite processing) on the plate 10.

  Thus, an alumite process was performed before performing electrodeposition coating, and the adhesion degree with the coating material used for subsequent coating can be improved.

  Moreover, it is preferable to include at least a melamine resin in the paint used in the electrodeposition coating. This melamine resin is used as an abrasive or a dirt remover, and the component ratio is 5 to 20% by weight, preferably 10 to 15% by weight.

  Further, the thickness of the coating film 11 is at least 15 μm or more. Thus, since it has sufficient thickness, it functions also as a buffer material which protects the surface of the board 10. Therefore, when a tool or the like is dropped or a hard article collides, the damage of the aluminum material is less than that of the bare one as before, and the commercial value as the scaffolding plate 1 may be significantly impaired. Absent.

  Moreover, in this embodiment, since it is electrodeposition coating, it is easy to adjust the thickness of the coating film 11 to the desired thickness, and the coating film 11 of arbitrary thickness can be formed at low cost.

  Thus, since the scaffold board 1 which concerns on this embodiment has the coating film 11 of sufficient thickness formed in the surface of the board 10, while protecting a foot scene, surface property of a foot scene However, it has a higher density than the surface properties of the aluminum material, the peelability of building materials containing cement such as ready-mixed concrete and mortar is increased, and the attached building materials (ready concrete and mortar) can be easily peeled off.

  For example, if the building material is small, it can be easily peeled off by high-pressure washing with water or the like. On the other hand, if the building material is a large lump, the large lump can be easily peeled off by hitting it with a hammer or the like, and even if a small lump remains on the surface of the plate 10, Similarly, it can be easily peeled off by high-pressure cleaning.

  Therefore, for example, for a leasing company such as a building material such as a scaffold, even if the surface of the scaffolding board 1 returned from the lease destination is soiled with raw concrete or mortar, these are easily peeled off to the next lease. It can be provided, and the work that has conventionally been time-consuming to remove mortar and the like is unnecessary, and the maintenance cost is greatly reduced.

  By the way, although formation of the coating film 11 in this embodiment was electrodeposition coating, it is good also as baking coating. In short, it is only necessary to form a film on the surface of the aluminum material and to change the surface properties so that the peeling performance with respect to raw concrete or mortar is improved as compared with the aluminum material.

  In the present embodiment, the scaffold plate 1 used for the temporary scaffold has been described as a type that is placed on the crosspiece pipe 4. However, for example, as shown in FIG. 2 may be attached, and the locking hook 2 may be of a type that engages with the crosspiece pipe 4.

  Moreover, the scaffold board 1 in which the coating film 11 is formed on the surface of the plate body 10 is not only a temporary scaffold as in this embodiment, but also a mobile worktable that is an example of a scaffold platform as shown in FIG. It can also be applied.

  As shown in the figure, the mobile work table has a structure in which four scaffolds 5 are pivotally connected to a scaffold plate 1 made of a top plate so as to be foldable. The leg column 5 is configured such that the sub-leg portion 51 is slidably inserted into the hollow main leg portion 50 so that the leg column 5 can be expanded and contracted. The casters 6 are respectively attached to the lower ends of the leg columns 5 and 5 at the side end portions without being grounded in a normal standing state.

  In addition to the footnote 5, if there is a part using an aluminum material in addition to the scaffold plate 1, the coating film 11 having a predetermined thickness can be formed on the surface thereof.

  From the embodiment described above, the following scaffolding can be realized.
