Description

発明の分野
本発明は足場板に関する。 FIELD OF THE INVENTION The present invention relates to scaffolding boards.

背景
建設、解体、改築、保守および他の建築作業の際に足場を使用することは周知されておりかつ広く普及している。足場は通例、垂直建地、水平布地および水平無目の直線的枠組の仮設物を含む。建地、布地および無目は、通例、クランプによって相互に連結される鋼管である。足場板は、高所作業台を提供するために無目に跨って配置される。足場板は通常、無垢材または単板積層材（LVL）で製造される。 BACKGROUND The use of scaffolds in construction, demolition, remodeling, maintenance and other construction operations is well known and widespread. Scaffolds typically include vertical foundations, horizontal fabrics and temporary structures in a horizontal linear framework. Construction sites, fabrics and blindness are usually steel pipes interconnected by clamps. The scaffolding board is blindly placed to provide a height platform. Scaffold boards are usually manufactured from solid or veneer laminate (LVL).

比較的高価であること、比較的重いこと、腐敗しやすいこと、耐紫外線性がないこと、可燃性であること、化学物質汚染に耐性がないこと、カビ胞子や細菌の繁殖に抵抗性がないこと、および再利用可能でないことを含む、無垢材またはLVLの足場板に関連するいくつかの欠点がある。   Being relatively expensive, being relatively heavy, being susceptible to rot, being non-UV resistant, being flammable, not being resistant to chemical contamination, not being resistant to the growth of mold spores and bacteria There are several disadvantages associated with solid wood or LVL scaffolding boards, including that they are not reusable.

米国特許出願公開第2013/0192927号（出願番号第13/754212号）（特許文献１）は、ポリ塩化ビニル（PVC）で製造された代替的な足場板を開示している。開示の板は、上述の欠点のいくつかを克服する（例えば、開示の板は、腐敗せず、耐紫外線性があり、かつ再利用可能である）。しかしながら、それら足場板は、荷重下での高い撓み性という大きな欠点を有する。そのようなものとして、それら足場板は、様々な国際規格およびオーストラリア規格、特に足場板の撓み検査に合格せず、この撓み検査は、（オーストラリアやニュージーランドでは）中央に適用される使用荷重限界（例えば210kg）に応答して撓みが1mスパンにわたって10mm未満である必要がある。結果として、この製品は、オーストラリア、米国、英国、カナダ（これらの国は同様の規格を有する）および他の多くの重要な建築市場では使用することができない。   US Patent Application Publication No. 2013/0192927 (Application No. 13/754212) (Patent Document 1) discloses an alternative scaffold board made of polyvinyl chloride (PVC). The disclosed boards overcome some of the above-mentioned drawbacks (e.g. the disclosed boards are non-perishable, UV resistant and reusable). However, they have the major disadvantage of high flexibility under load. As such, the scaffolding boards do not pass the various international and Australian standards, in particular the deflection inspection of the scaffolding board, this deflection inspection being used at the center (in Australia and New Zealand) the working load limit ( The deflection needs to be less than 10 mm over 1 m span in response to, for example, 210 kg. As a result, this product can not be used in Australia, the United States, the United Kingdom, Canada (these countries have similar standards) and many other important construction markets.

別の公知の代替的な足場板は繊維強化プラスチック（FRP）で製造されている。この足場板もまた、木材/LVL板のいくつかの同様の欠点を克服する。しかしながら、この足場板はまた、比較的重い製品であり、可燃性の高いタイプのプラスチック材料から作製され、再利用が極めて困難であり、かつほどほどに高い温度での極めて高い撓み性を有する。結果として、この製品は、非常に限られた用途にのみ適している。   Another known alternative scaffolding board is made of fiber reinforced plastic (FRP). This scaffolding board also overcomes some of the similar disadvantages of wood / LVL boards. However, this scaffolding board is also a relatively heavy product, made of a highly flammable type of plastic material, very difficult to reuse and has very high flexibility at moderately high temperatures. As a result, this product is only suitable for very limited applications.

さらなる公知の代替的な足場板はポリプロピレンで製造されている。この足場板は、オーストラリアの規格も満たしていない。板は、黒色であり、太陽光で著しく柔軟になる。板はまた、発火して炎を移し得る。   A further known alternative scaffolding board is made of polypropylene. This scaffold does not meet Australian standards. The board is black and becomes extremely soft in sunlight. The board can also ignite and transfer flames.

足場板はまた、比較的高い材料費および作製費ならびに比較的高重量の点で同様の欠点がある、アルミニウムから作製されている。   The scaffolding board is also made of aluminum, which has similar disadvantages in terms of relatively high material and production costs and relatively high weight.

発明の目的
本発明の目的は、上記の欠点の1つまたは複数を実質的に克服するかまたは少なくとも改善することである。 Objects of the invention The object of the present invention is to substantially overcome or at least ameliorate one or more of the above-mentioned drawbacks.

Figure 2019512620
Detailed Description of the Preferred Embodiments FIGS. 1-3 show a first embodiment of a scaffolding board 10 made from polyvinyl chloride (PVC) thermoplastic material by extrusion. As an example, PVC k62 or k66 is used in the following proportions per 100 parts of PVC resin.
Figure 2019512620

当業者であれば理解するように、上記成分は、特定の用途、気候および温度範囲に適するように配合率を調整するために増加または減少させることができる。   As those skilled in the art will appreciate, the above components can be increased or decreased to adjust the formulation to suit the particular application, climate and temperature range.

板10は、既存の足場設備に適するように既存の木材板の寸法に適合した寸法で作製される。板10は、幅230mm、厚さ39mm（以下で論じる熱間圧延グリップを含む）であり、2400mmおよび3600mmの長さで作製される。   The board 10 is made with dimensions adapted to the dimensions of existing wood boards to be suitable for existing scaffolding equipment. The plate 10 is 230 mm wide, 39 mm thick (including the hot rolled grip discussed below) and is made in lengths of 2400 mm and 3600 mm.

図2に最もよく示すように、板は、上壁12と、底壁14と、側壁16および18の対とによって画定された実質的に矩形の外形輪郭を有する。壁12、14、16および18はすべて約4mmの厚さである。各々が上壁12の内面と底壁14の内面との間に延びる、全体として参照符号20で示す複数の補強材を除いて、板10の内部は、実質的に中空である。   As best shown in FIG. 2, the plate has a substantially rectangular outline defined by the top wall 12, the bottom wall 14 and the pair of side walls 16 and 18. The walls 12, 14, 16 and 18 are all about 4 mm thick. The interior of the plate 10 is substantially hollow, except for a plurality of reinforcements, generally indicated by the reference numeral 20, each extending between the inner surface of the top wall 12 and the inner surface of the bottom wall 14.

補強材20は各々、上部部分20aおよび20bの対と、中間部分20cと、下部部分20dおよび20eの対とを有し、これらはすべて厚さが約3mmである。上部部分20aおよび20bは各々、中間部分20cの上部から上壁12の内面に向かって外方に、実質的に等しいが反対の方向にそれぞれ延びる。下部部分20dおよび20eは各々、中間部分20cの下部から底壁14の内面に向かって外方に、実質的に等しいが反対の方向にそれぞれ延びる。上部部分20aおよび20bの対の各々は、上壁12の隣接内面と共に三角形の長手方向凹部22を画定する。同様に、下部部分20dおよび20eの対は各々、底壁14の隣接内面と共に三角形の長手方向凹部24を画定する。六角形の長手方向凹部26は、隣り合う補強材間に画定される。   The stiffeners 20 each have a pair of upper portions 20a and 20b, a middle portion 20c, and a pair of lower portions 20d and 20e, all of which are about 3 mm thick. The upper portions 20a and 20b each extend outwardly from the upper portion of the middle portion 20c toward the inner surface of the upper wall 12 in substantially equal but opposite directions, respectively. Lower portions 20d and 20e each extend outwardly from the lower portion of middle portion 20c toward the inner surface of bottom wall 14 in a substantially equal but opposite direction, respectively. Each pair of upper portions 20a and 20b, together with the adjacent inner surface of upper wall 12, define a triangular longitudinal recess 22. Similarly, the pair of lower portions 20 d and 20 e each define a triangular longitudinal recess 24 with the adjacent inner surface of the bottom wall 14. Hexagonal longitudinal recesses 26 are defined between adjacent reinforcements.

板10が押出成形されるので、上壁12、下部14、側壁16および18、ならびに補強材20はすべて、板10の全長にわたって長手方向に延びる。上壁12、底壁14、側壁16および18、ならびに補強材20はまた、一体的に形成される。   As the plate 10 is extruded, the upper wall 12, the lower portion 14, the side walls 16 and 18 and the stiffeners 20 all extend longitudinally along the entire length of the plate 10. Top wall 12, bottom wall 14, side walls 16 and 18, and stiffener 20 are also integrally formed.

図3に最もよく示すように、上壁12および底壁14の外面は、グリップ性を高めるために外面に形成された多数の長手方向（滑り止め）突条28を含む。突条28は、テクスチャ加工された熱ローラを使用して形成される。   As best seen in FIG. 3, the outer surfaces of top wall 12 and bottom wall 14 include a number of longitudinal (non-slip) ridges 28 formed on the outer surface to enhance grip. The ridges 28 are formed using a textured heat roller.

内部補強材20を説明する別の方法は、これらが一緒になって、長手方向に延びるセル30の列によって画定される内部ハニカム補強構造を形成することである。六角形の最長寸法が上壁12および底壁14の平面に直交する向きに配置された六角形によって、セル30の各々が画定される。   Another way of describing the internal reinforcements 20 is to combine them to form an internal honeycomb reinforcement structure defined by a row of longitudinally extending cells 30. Each of the cells 30 is defined by hexagons whose longest dimension is oriented orthogonal to the plane of the top wall 12 and bottom wall 14.

図4は、足場板10'の第2の態様を示している。板10'は、先に説明したものと同様であり、類似の特徴を表すために類似の参照符号が使用される。しかしながら、板10'では、補強材20が僅かにより広い間隔をおいて配置され、その結果、補強材20間に八角形凹部26'が得られる。   Figure 4 shows a second embodiment of the scaffolding plate 10 '. The plate 10 'is similar to that described above and similar reference numerals are used to represent similar features. However, in the plate 10 ′, the stiffeners 20 are spaced slightly wider, resulting in octagonal recesses 26 ′ between the stiffeners 20.

板10/10'の構造、特に補強材およびハニカムセルは、優れた曲げ剛性と前述のオーストラリア規格の撓み検査に合格する能力とを板10/10'に与える。板10/10'はまた、それぞれ重さが10.8kgおよび16.2kgである2400mmおよび3600mmの長さの板に関して先に論じた公知の板よりも軽量である。この軽量化によっていくつかの利点がもたらされる。第1に、軽量化によって、板を作製するのに必要な材料が低減され、これにより、製造費および作製費が削減される。輸送費および手作業費も低減される。第2に、板10は、複数の足場高さ間を階段および/または梯子で運ばれるのとは対照的に、足場構造の組立または解体中に複数の高さ間で手渡しできるほど十分に軽量であり、それらの両作業の時間を大幅に短縮する。   The construction of the board 10/10 ', in particular the reinforcements and the honeycomb cells, give the board 10/10' an excellent bending stiffness and the ability to pass the aforementioned Australian standard deflection test. The board 10/10 'is also lighter than the known boards discussed above for the 2400 mm and 3600 mm lengths of boards weighing 10.8 kg and 16.2 kg, respectively. This weight reduction provides several advantages. First, the weight reduction reduces the material needed to make the board, which reduces manufacturing and manufacturing costs. Shipping costs and manual costs are also reduced. Second, the board 10 is lightweight enough to be handed over between heights during assembly or disassembly of the scaffolding structure, as opposed to being carried by stairs and / or ladders between scaffolding heights And significantly reduce the time for both of them.

板10/10'はまた、腐敗しないこと、紫外線に強い耐性があること、自己消炎性、高い耐衝撃性、高い耐腐食性、放射性粒子の移動を許容しないこと、アスベストを含むある範囲の化学物質により汚染されないこと、カビ胞子や細菌の増殖を許容しないこと、昆虫の侵入を許容しないこと、再利用可能でかつ環境的に持続可能であること、異なる用途のために容易に区別できるように制御可能であることを含む、木製/LVL板の熱可塑性構造に関連する他の利点を維持する。   Plates 10/10 'are also non-perishable, highly resistant to ultraviolet light, self-extinguishing, high impact resistance, high corrosion resistance, not allowing movement of radioactive particles, a range of chemistries including asbestos Not to be contaminated by substances, not to allow growth of mold spores and bacteria, not to allow insects to enter, to be reusable and environmentally sustainable, easily distinguishable for different applications Maintaining other advantages associated with the wood / LVL board thermoplastic construction, including being controllable.
