クリートからなる捨枠に関するものである。[Detailed description of the invention] [Industrial field of application] The present invention applies to conventional steel used when creating wave-dissipating concrete blocks, wave-dissipating caissons, or retaining walls, breakwaters, embankments, seawalls, dams, and other civil engineering structures. This relates to a pre-cast concrete formwork that can be used as an alternative to wooden or board formwork.

法が存する。[Prior art] Conventionally, at a construction site, the old-fashioned method of assembling a desired shape with reinforcing bars, placing a steel formwork around it, and pouring cast-in-place concrete into it, or using precast members. There are methods to use.

ことが多い。[Problems that the invention aims to solve] However, at construction sites, the assembly and disassembly of formwork and shoring, and the placement and installation of processed reinforcing bars not only require a significant amount of manpower and time, but also the dimensions and reinforcing bars at small sites. Inspecting placement is also often difficult.

る。[Means for solving the problem] The inventors have developed a structure in which the PC members are not only used as shedding plates for formwork, but also can independently support the concrete pouring load without the need for shoring. Furthermore, after pouring cast-in-place concrete, the total amount of reinforcing bars required for the reinforced concrete members of the entire structure integrated with the cast-in-place concrete is determined in advance by PC.
By arranging some parts exposed and some buried inside the members, the reinforcement work on site is minimized, and the exposed reinforcing bars are used to structurally integrate the PC members and cast-in-place concrete. By forming ribs on the surface of the PC member, it is possible to strengthen the bond between the two members.
［実施例］

一部をPC部材から露出させても良い。 In Fig. 1, all the main reinforcing bars 1 corresponding to the total amount of reinforcing bars required for the floor slab structure (the entire area including the shaded area) are buried in the PC member 2. This main reinforcement, on which ribs 5, 6, and 7 are formed on the surface of the PC member, may be partially exposed from the PC member.

に経費の節減が図れる。[Effects of the invention] As described above, according to the waste frame of the present invention, if the total amount of reinforcing bars required for the structure to be created is calculated and embedded in the waste frame in advance, the reinforcing bars can be placed at the work site. Installation work can be omitted, and since this waste frame can also be used as a formwork, there is no need to assemble or dismantle formwork and shoring, resulting in a significant reduction in working time and costs.

達用埋設物といつた余計なものが不要となる。 In addition, the exposed parts of the distribution bars and main threads are useful for structurally integrating the waste frame and cast-in-place concrete, so there is no need for unnecessary items such as buried objects for transmitting shear force that are required to make the two into a composite structure. becomes.
さらにまた、捨枠は工場にて生産できるので、
