単一杭の鉛直引抜抵抗の静荷重試験は、鉛直引抜抵抗杭の実際の作動条件に接近する試験方法を採用し、それは、単一杭の鉛直引抜抵抗の限界耐荷能力を決定し、最も直観的であり、最も信頼できる方法であるが、従来の静荷重引抜抵抗試験機器を使用する時に、それは、単一杭に対して鉄筋を接続する方式が煩雑であり、鉄筋を機器の接続リング上に貼り付ける必要があり、鉄筋の形状を変え、工事の進度に影響を与えるだけでなく、試験が終わった後に杭基礎のアンカーに埋め込まれた鉄筋への損傷が極めて大きく、それによって杭基礎と底板の品質に影響を与える。 The static load test of vertical pull-out resistance of a single pile adopts a test method that approaches the actual operating conditions of the vertical pull-out resistance pile, which is the most intuitive and most reliable method to determine the ultimate load-bearing capacity of the vertical pull-out resistance of a single pile. However, when using traditional static load pull-out resistance test equipment, the method of connecting the rebar to the single pile is complicated, and the rebar needs to be attached to the connection ring of the equipment, which not only changes the shape of the rebar and affects the progress of the construction, but also causes significant damage to the rebar embedded in the anchor of the pile foundation after the test is completed, thereby affecting the quality of the pile foundation and the bottom plate.
本考案は、以下のような技術案を提供する。単一杭の鉛直静荷重引抜抵抗試験を向上させる装置は、杭面と台板とを含み、前記杭面の表面に固定ブロックと鉄筋が固定的に接続され、前記固定ブロックの表面に支持ブロックが当接して接続され、前記支持ブロックの表面に当接板が当接して接続され、前記当接板の表面に支持柱が固定的に接続され、前記台板の表面に接続ロッドが嵌合して接続され、前記台板の表面に調節溝が貫通して開けられ、前記接続ロッドの外面にガスケットが嵌着され、前記接続ロッドの外面にネジを介して螺着リングが嵌着される。 The present invention provides the following technical proposal: A device for improving vertical static load pull-out resistance testing of a single pile includes a pile face and a base plate, a fixed block and a reinforcing bar are fixedly connected to the surface of the pile face, a support block is abutted and connected to the surface of the fixed block, an abutment plate is abutted and connected to the surface of the support block, a support column is fixedly connected to the surface of the abutment plate, a connecting rod is fitted and connected to the surface of the base plate, an adjustment groove is opened through the surface of the base plate, a gasket is fitted to the outer surface of the connecting rod, and a screw ring is fitted to the outer surface of the connecting rod via a screw.

The abutment connection between the abutment plate 5 and the support block 4, and the connection between the support column 6 and the base plate 7, achieves a support control effect on the operating position of the base plate 7.
さらに、台板７は、支持柱６を介して杭面１の上方に作用し、支持柱６と当接板５は、二組で台板７の両端に分布しており、台板７と支持柱６との接続、支持柱６と当接板５との接続により、支持柱６の作用で、台板７の支持ブロック４における作用位置に対する支持効果を実現する。 Furthermore, the base plate 7 acts above the pile surface 1 via the support columns 6, and the support columns 6 and the abutment plates 5 are distributed in two sets at both ends of the base plate 7.

さらに、ガスケット１０は、接続ロッド８を介して台板７と当接して接続され、螺着リング１１は、接続ロッド８を介してガスケット１０と当接して接続され、ガスケット１０と接続ロッド８との接続で、螺着リング１１と接続ロッド８との接続により、接続ロッド８の台板７における作用位置に対する支持効果を実現する。 Furthermore, the gasket 10 is connected to the base plate 7 via the connecting rod 8, and the screw ring 11 is connected to the gasket 10 via the connecting rod 8, and the connection between the gasket 10 and the connecting rod 8 and the connection between the screw ring 11 and the connecting rod 8 provide a support effect for the operating position of the connecting rod 8 on the base plate 7.
作動原理：鉄筋３に対して引抜抵抗試験を行う時に、先ず当接板５を該当する支持ブロック４上に置き、当接板５と支持柱６との接続、支持柱６と台板７との接続で、台板７の作用位置に対する支持を達成し、その後に接続ロッド８を鉄筋３と共に溶接し、接続ロッド８とガスケット１０との接続、螺着リング１１と接続ロッド８との接続で、接続ロッド８の台板７における作用位置に対する制御支持効果を実現し、調節溝９の作用で、接続ロッド８の台板７における作用位置を変え、接続ロッド８の台板７における使用範囲と性能を向上させる。 Operating principle: When conducting a pull-out resistance test on the reinforcing bar 3, first place the abutment plate 5 on the corresponding support block 4, and connect the abutment plate 5 to the support column 6, and then connect the support column 6 to the base plate 7 to achieve support for the working position of the base plate 7.
