である。2. Description of the Related Art In the conventional slip-form construction method, as shown in FIG. 3, a mold 11 is supported by a yoke 11 via a waving member 15 and embedded in a concrete wall 17 having been cast. It is a construction method in which the yoke 11 is pulled up together with the mold 14 and the scaffold 16 by the jack 18 provided on the rod 12.

がある。In this case, the yoke is U-shaped and holds the molds on both sides of the concrete wall. Therefore, the horizontal lateral pressure of concrete before setting is balanced and stable on both sides of the wall. Since the structure is as described above, if there is an existing structure, the yoke is not used and the slip-form construction method cannot be applied.

を提供することを課題とするものである。Further, in order to launch concrete along an existing structure, a method of taking a separator from existing concrete and supporting a formwork has been conventionally used. However, in this case, the position of the separator attached to the existing structure and the through hole of the mold may not be aligned, and this adjustment took time. Therefore, it has been desired to apply a slip-form construction method that does not require a separator. SUMMARY OF THE INVENTION It is an object of the present invention to provide a slip forming method capable of solving the above problems.

ものである。The slip fork of the present invention
The mud construction method is that when the concrete wall is sequentially cast upward along the existing structure, the form supporting member is separated in the middle and is supported by the existing structure through the connectable support member. The supporting member which is an obstacle to the ascent is separated to raise the mold, and after the mold passes through the supporting member, the operation of connecting the supporting members is repeated, and the concrete wall is sequentially installed along the existing structure. It is characterized by being set up.

ようにロッドを壁中に埋め込む作業は不要となる。The form supporting member is supported by the existing structure through the support member, and by suppressing the amount of deformation of the form supporting member, the protrusion of the form can be suppressed and the form can be easily raised. Further, since the support member can be separated and connected, it does not hinder the raising of the mold. Since the force of raising the formwork can be taken from the existing structure, the work of embedding the rod in the wall as in the conventional case is unnecessary.

Are provided at predetermined intervals in the height direction and the lateral direction so that the amount of deflection can be suppressed without any problem, for example, about 2 mm. The anchor bolt, which is the support member 2, can be separated and connected via the nut 3 at the surface position of the mold 4.

When these operations are repeated and the mold 4 is raised, when it comes into contact with the anchor bolt 2 which is a support member, the anchor bolt is separated at the nut 3 and the mold 4 is raised. After passing through the formwork 4, the anchor bolts 2 which are support members are connected again via the nuts 3 to support the formwork support member 1.

The form supporting member is supported by the existing structure through the supporting member, and the amount of deformation of the form supporting member is suppressed to form the form. It is possible to suppress the protrusion of the mold and to easily raise the formwork. Further, since the support member can be separated and connected, it does not hinder the raising of the mold. Since the force for raising the formwork can be taken from the existing structure, the work of embedding the rod in the wall as in the conventional case is unnecessary.
