Abstract
Description
本発明は、コンクリート製で岩石や流木により衝撃を受ける砂防ダム、橋脚等のコンクリート構造物を施工する際に、コンクリート構造物の衝撃を受ける表面を保護するため、コンクリート構造物に壁板として固着させるゴム製耐衝撃用保護板に関する。 The present invention is made of concrete and is attached to a concrete structure as a wall plate in order to protect the impact surface of the concrete structure when constructing a concrete structure such as a sabo dam or bridge pier that is impacted by rocks or driftwood. The invention relates to a rubber shockproof protective plate.
従来、砂防ダムや橋脚等のコンクリート構造物を岩石や流木等の衝突から保護するために、ゴム製の保護部材がコンクリート構造物の表面に固着されている。この保護部材としては、特開２００３−２３９２５６号に開示されたゴム製耐衝撃用残存型枠においては、型枠部材の裏面から多数の直棒状の結合部材を突出させたものである。
上記従来のゴム製耐衝撃用残存形枠は、コンクリート構造物に固着させた状態において、充分な耐衝撃性及び耐久性を有するが、多数本の結合部材が型枠部材から突出しているため、保管や運搬時に嵩張り、そのための保管スペースが余分に必要となり、また運搬時においても結合部材が邪魔となり積み下ろしに手間を要し、これらの費用が嵩む問題点を有していた。 The conventional rubber impact resistant residual form has sufficient impact resistance and durability in a state where it is fixed to a concrete structure, but since a large number of coupling members protrude from the formwork member, It is bulky at the time of storage and transportation, and an extra storage space is required for that purpose, and the connecting member is obstructive at the time of transportation.
また、前記残存型枠においては、枠組の際にこの残存型枠同志や他の残存型枠との接続が難しい。つまり、突出した状態の前記結合部材に連結部材を溶接して接続する枠組となり、枠組した状態が正確性を欠き、且つ、手間を要していた。 Further, in the remaining mold, it is difficult to connect the remaining molds and other remaining molds at the time of frame formation. In other words, a frame is formed in which the connecting member is welded and connected to the protruding coupling member, and the framed state lacks accuracy and requires time and effort.
本発明は、前記問題点に鑑み、保管や運搬に便利で、しかも耐衝撃性に強いゴム製耐衝撃用保護板を提供することを目的とする。 In view of the above problems, an object of the present invention is to provide a rubber impact protection protective plate that is convenient for storage and transportation and has high impact resistance.
本発明の他の目的は、コンクリート構造物の施工において本発明の保護板を残存型枠として使用する際に、それ自体同志や他のコンクリート製の残存型枠との接続が容易で、且つ強固で正確な枠組ができるゴム製耐衝撃用保護板を提供するにある。 Another object of the present invention is that, when the protective plate of the present invention is used as a remaining mold in the construction of a concrete structure, it is easy to connect with each other and other remaining molds made of concrete and is strong. It is to provide a rubber shock-resistant protective plate that can be accurately framed.
本発明は、ゴムチップをバインダーで固めた四角状の保護板本体（１）と、その保護板本体（１）内に埋設する補強部材（２）と、該補強部材（２）と固着し前記保護板本体（１）の裏面（1a）側に埋設した複数の高ナット（３）とから成るものである。 The present invention provides a rectangular protective plate main body (1) in which rubber chips are hardened with a binder, a reinforcing member (2) embedded in the protective plate main body (1), and the protective member fixed to the reinforcing member (2). It consists of a plurality of high nuts (3) embedded on the back surface (1a) side of the plate body (1).
又、前記補強部材（２）が、網状に組んだ鉄筋棒であるのが好ましい。この場合には、ゴムチップをバインダーで固めて保護板本体（１）を成形する際に、鉄筋棒を網状に組んだことにより、バインダーを混ぜ合せたゴムチップが補強部材（２）の網目を通過でき、成形金型内に充分行き渡るため、空洞のない強固な保護板本体（１）が成形できる。 Moreover, it is preferable that the reinforcing member (2) is a reinforcing bar assembled in a net shape. In this case, when the rubber chip is hardened with a binder and the protective plate body (1) is formed, the reinforcing bar is assembled in a net shape so that the rubber chip mixed with the binder can pass through the mesh of the reinforcing member (2). Since it is sufficiently distributed in the molding die, a strong protective plate body (1) without a cavity can be molded.
又、前記高ナット（３）が、少なくとも保護板本体（１）の四隅に設けるのが好ましい。これにより、保護板本体（１）とコンクリート構造物との固着性や枠組時に段積した保護板本体（１）を連結する場合にも、四隅に設けた高ナット（３）を利用して、接続金具（４）とボルト（５）でもって容易に連結できる（図３参照）。 The high nut (3) is preferably provided at least at the four corners of the protective plate body (1). Thereby, even when connecting the protective plate body (1) and the protective plate body (1) stacked at the time of framing, using the high nuts (3) provided at the four corners, It can be easily coupled with the connection fitting (4) and the bolt (5) (see FIG. 3).
本発明でいう保護板本体（１）の裏面（1a）側に埋設したとは、高ナット（３）が保護板本体（１）の裏面（1a）から突出せずに雄ネジと螺合可能に埋設した状態をいう。 By embedding on the back surface (1a) side of the protection plate body (1) in the present invention, the high nut (3) can be screwed into the male screw without protruding from the back surface (1a) of the protection plate body (1).

Since there is nothing protruding from 1), the completed protective plate of the present invention is not bulky when storing or transporting it as a product, and does not take up space, so that it is easy to store and transport and the cost for that is also low. .
また、保護板本体（１）に高ナット（３）を固着させたことにより、この高ナット（３）は、保護板本体（１）を残存型枠として使用する際、段積した互いの保護板本体（１）を接続するのに、四隅の高ナット（３）を利用して接続金具（４）とボルト（５）で容易に接続させることができると共に、高ナット（３）にネジ棒（６）を螺合させ、保護板本体（１）の裏面（1a）から突出させることにより、保護板本体（１）とコンクリート構造物とを強固に固着させることが可能となる。要するに、高ナット（３）を設けたことにより、この高ナット（３）を利用して種々のネジ部材が取付けられるため、枠組時の保護板本体（１）の接続の容易さと、保護板本体（１）とコンクリート構造物との強固な結合を同時に満足するものである。 In addition, since the high nut (3) is fixed to the protective plate body (1), the high nut (3) protects the stacked plates from each other when the protective plate body (1) is used as a remaining mold. To connect the plate body (1), the high nuts (3) at the four corners can be used for easy connection with the connecting bracket (4) and the bolt (5), and the high nut (3) is threaded By screwing (6) and projecting from the back surface (1a) of the protective plate body (1), the protective plate body (1) and the concrete structure can be firmly fixed. In short, by providing the high nut (3), various screw members can be attached by using the high nut (3), so that the protection plate body (1) can be easily connected when the frame is assembled, and the protection plate body. (1) satisfies the strong bond between the concrete structure and the concrete structure at the same time.

FIG. 1 is a cross-sectional view of the present invention, FIG. 2 is a plan view of the present invention, and FIG. 3 is an explanatory view showing a use state of the present invention.
図１、２において、（１）はゴムチップをバインダーで固めた四角状の保護板本体であり、ゴムチップとしては廃ゴム、特には廃タイヤが耐衝撃性に優れ、また、リサイクル化の促進及び安価な点で好ましい。また、バインダーはゴムチップを結合させるための接合剤であり、これにはウレタン系，アクリル系，エポキシ系等の接合剤が使用され、特にはウレタン系が耐衝撃性の点で好ましい。 In FIGS. 1 and 2, (1) is a rectangular protective plate body in which rubber chips are hardened with a binder. As rubber chips, waste rubber, especially waste tires are excellent in impact resistance, and recycling is promoted and inexpensive. This is preferable. The binder is a bonding agent for bonding the rubber chip. For this, a bonding agent such as urethane, acrylic or epoxy is used, and urethane is particularly preferable in terms of impact resistance.
（２）は補強部材であり、該補強部材（２）は、金属製で棒状のものを粗い網目の網状に組んで前記保護板本体（１）内に完全に埋設させている。 (2) is a reinforcing member, and the reinforcing member (2) is made of a metal rod-like material assembled into a net-like mesh and is completely embedded in the protective plate body (1).
そして、この補強部材（２）は、鉄筋棒で網状に組んだものが、安価で強度的にも強く、特に鉄筋棒は断面が丸棒で角がないため、保護板本体（１）内に埋設した状態で保護板本体（１）に衝撃力が加わっても、補強部材（２）による保護板本体（１）の損傷が極めて少なく、保護板本体（１）の耐久性の面でも好ましい。 And this reinforcing member (2), which is constructed in a mesh form with reinforcing bars, is inexpensive and strong in strength. Especially, the reinforcing bars are round bars and have no corners.
