本発明は土木、建築用コンクリート建造物を築造する場

The object is to completely block water permeation at the interface between the steel frame and the concrete or mortar to be placed by utilizing the property of the adhesive body to adhere to the concrete or mortar to be placed next.

ると共に大型構造鉄骨の利用で高層ビルの建築が可能と
なった。In recent years, there has been a growing demand for deeper underground structures in general building construction for the purpose of effective use of land area, and in line with technological innovations in construction methods, structural steel frames have been used to effectively support loads and simplify construction. This method was adopted, reducing construction costs and making it possible to construct high-rise buildings using large structural steel frames.
これら大型構造鉄骨を使用する工法ではコンクリートと
の界面を全面的に密着させる事は非常に困難で、確実に
施工出来ないのが実情である。With these construction methods that use large structural steel frames, it is extremely difficult to achieve complete contact with the interface with concrete, and the reality is that construction cannot be performed reliably.
大型構造鉄骨は地中に深く打込まれるために水脈を貫通
し、又、地下水は構造鉄骨の界面を伝導する可能性は非
常に高い確率である。Since large structural steel frames are driven deeply into the ground, there is a very high probability that they will penetrate water veins and that groundwater will be conducted through the interface of the structural steel frames.
又、大型建造物では地下構造を造築する場合に作業場、

通して地下水の噴出する可能性は犬である。In addition, when constructing an underground structure for a large building, a workshop,
Scaffolding and other equipment such as cranes may be installed. In this case, it is necessary to install a temporary supporting steel frame. When removing a work area such as a platform after construction is completed, the temporary supporting steel frame must be cut near the bottom end. There is a small possibility that spring water that has traveled through the interface of supporting steel frames that are driven deep into the ground will gush out through the concrete of the foundation, which is at almost the same level as the ground level.

ある。Conventionally, the upper part of the cut support steel frame was buried in concrete mixed with rubber latex or synthetic resin emulsion to make it waterproof and watertight, but it was very uncertain and caused earthquakes, vibrations, and other problems. If there is subsidence, cracks are inevitable even if the concrete contains resin or latex, and the reality is that water leaks occur.

のである。Here, as shown in FIG. 1 showing an example of implementation, the present invention applies a viscoelastic adhesive composition 2 made of recycled rubber as a base material to the interface of an underground supporting steel frame 1 cast into a foundation concrete 3. If it is adhered to the outer circumferential surface near the lower end of 1 without any gaps and buried in the concrete of concrete building 4, water introduction from the steel frame interface will be blocked, and water will not gush into the underground floorboard completely. This is related to construction methods that can prevent this.

た。Examples of formulations of adhesive compositions based on recycled rubber and examples of adhesion to concrete or mortar, adhesion to iron surfaces, etc. are as follows: (1) Examples of formulations of adhesive compositions Measurement method Vertical shear tension Test Note) The fracture interface is a cohesive failure of the material.As shown above, the adhesive composition based on butyl recycled rubber allows the concrete and adhesive composition to adhere without causing interfacial failure at the same time as the concrete or mortar hardens. We obtained the following results.

故に本発明の止水施工法は、機能的にもコンク’Ｊ −

施工法である。Therefore, the water stop construction method of the present invention is functionally effective as well.
This is a construction method that uses materials that have sufficient adhesion to steel surfaces.

水を遮断して止水、防水が完全に行えるものである。Specifically, a recycled rubber-based adhesive composition is firmly adhered to a part of the structural steel frame or the steel frame used as a temporary supporting steel frame, and then it is buried in concrete or a floor slab is poured. It is completely watertight and waterproof by blocking spring water from deep underground.

通水、透水する可能性は全くない。The adhesive composition according to the present invention has a very high elongation ability, so that misalignment occurs in the behavior of the structural steel frame and the structural concrete when subjected to uneven ground subsidence or earthquakes or other vibrations. Even in this case, the behavior is followed by the deformation and elongation of the adhesive composition itself, so there is no possibility that the water stop location will break and allow water to pass through.

ある。As described above, the present invention has the functional effect of adhering a viscoelastic adhesive composition using recycled rubber as a base material to a part of a structural steel frame, and then pouring concrete or mortar to bond the two. This is a waterproofing and water-stopping construction method characterized by using an adhesive composition that has the property of elongating and following the behavior of external factors such as earthquakes, uneven settlements, etc. without breaking.
