Description

Technical Field [0001] The present invention relates to a method of constructing a composite wall having a vertical non-reinforced reinforced concrete structure,

The present invention relates to a composite-wall which comprises an integral wall by filling (casting and curing) a site concrete between two inner and outer precast concrete plates in which vertical and horizontal reinforcing bars are arranged, In the composite zone, which is an internal space, the problem of member displacement due to external force is eliminated (securing structural strength) by allowing the concrete (concrete installation) process to be performed immediately without installing and disassembling various scaffolding including vertical reinforcement work Of course, it is of course possible to drastically shorten the air, reduce the work cost by omitting the field work and omission of the installation material, to reduce the cost of the work (for example, the vertical reinforcement is not required and the inner and outer plates of the high- And the inner and outer plates are formed so as to significantly improve the strength of the inner and outer plates, It is possible to greatly improve the joining property with the foundation bottom portion and to allow the vertical reinforcing bars necessary for the structural strength to be entirely placed in the PC member without increasing the thickness of the PC member, The construction and economical efficiency are greatly improved due to the absence of other supports and construction materials. In particular, the inner and outer plates assembled integrally from the factory to the coupler (shear joint unit) , And is capable of minimizing the occurrence of breakage and cracking during transportation due to an increase in the width of the cross section, and the method of constructing the composite-wall structure and the composite-wall structure having the local vertical reinforcing- .

Generally, a structure or a structure is formed after a foundation (floor) after a terrage (civil engineering work), and an outer wall is constructed by an RC concrete method using a mold thereon, and a slab is formed at the upper end of the outer wall.

Therefore, in the outer wall construction by the RC method in the related art, the reinforcing bars are firstly laid in order to set up the wall, the concrete is installed in the formwork after the concrete is installed and the concrete wall is cured, It is troublesome to install and remove scaffolds one by one, and there is a disadvantage that the construction period is lengthened and the construction cost is increased.

In addition, when the height of the outer wall is increased due to the high height of the floor, the side pressure (bending moment) acting on the form becomes considerably large, which may cause a safety problem. It became a cause.

In the case of a large space structure such as a storage tank, an underground parking lot, and a warehouse, an outer wall having a floor height of about 10 to 20 m is required. In this structure, the RC construction method has a longer construction period, The workability and productivity of various construction materials are greatly decreased, and the construction cost is greatly increased.

In order to improve this, recently, as shown in Patent Application No. 10-2010-0084034, a PC member is manufactured and assembled in situ. However, in the case of a wall member (or a column) The thickness of the PC member becomes thick for the structural rigidity and various supports and construction material are required. Especially, the design is not reflected in the efficiency of the bending moment and the shearing force, There is a problem that structural uneasiness is still present, and in addition, since such a method is used for replacing a formwork in a field, it is necessary to carry out the rebar work on site and the scaffolding work to do the same, It is difficult to expect a great effect.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and its technical object is to provide a composite structure in which a concrete structure is filled (cast and cured) between two inner and outer plates, In the composite zone, which is the inner space of the composite-wall, in the month, the concrete (cast-in-place) process is performed immediately without installing and disassembling various scaffolds including the vertical bar reinforcement, And the cost is reduced due to the reduction of field work and the omission of subsidiary materials. In addition, it is possible to reduce troublesome workability (for example, it is unnecessary to install vertical reinforcing bars, , The outer plate is assembled so as to face each other and then laid down laterally to perform a coupling operation), and the inner and outer A hatch block having a sleeve at the lower portion of the plate is formed to greatly improve the bonding property with the foundation bottom portion and to allow the vertical reinforcing bars necessary for structural strength to be entirely placed in the PC member without increasing the thickness of the PC member, The work can be omitted and the standability (and stand-up) can be achieved. Therefore, the workability and economical efficiency can be greatly improved due to the absence of other support members and the installation material. Especially, the fact that the coupler (shear joint unit) And the outer plate is transported in a side-by-side manner as an integral wall plate, whereby breakage and cracking during transport can be minimized owing to an increase in width section. And a method of constructing the composite-wall.

  4. The internal plate (100) according to claim 1, wherein the inner plate (100) has a shear reinforcement rope (140) coupled to the outer sidewall (111), wherein the shear reinforcement rope A connecting tip 142 connecting the both ends 141 of the arms is formed to be embedded in the inside plate 100 and the both ends 141 of the arms 141, A screw-engaging coupler 150 is coupled to the end of the screw;
    The outer side plate 200 is formed with a synthetic zone Z while facing the inner side plate 100 at a predetermined distance from the inner side plate 100. On the inner side wall surface 211 of the outer side plate 200, The second shear reinforcement 240 is formed such that the second extremity 241 of the second shear reinforcement 240 is branched outwardly from the inner side wall 211, 241 are formed to be embedded in the outer plate 200 and the second extremity 241 of the second arm is formed in the synthetic zone Z with a screw- And is formed so as to form a quadrangular shear joint unit (U) integrally with both the arm ends (141) of the inner side plate.
  5. The internal plate (100) according to claim 1, wherein the inner plate (100) has a shear reinforcement rope (140) coupled to the outer sidewall (111), wherein the shear reinforcement rope The connection tip 142 connecting the both ends of the arms 141 and 141 is formed to be embedded in the inner side plate 100,
    The outer plate 200 is formed in a synthetic zone Z while facing the inner plate 100 with a predetermined distance therebetween. The outer plate 200 has a coupling groove 215- 1) is formed so that when the end side thread portion of the inner side plate 141 of the inner side plate is introduced, the inner side plate is fastened and assembled by the coupling nut 216.
  6. [5] The apparatus as claimed in claim 4 or 5, wherein the shear reinforcement and the second shear reinforcement are connected to each other at a joint end (and a second joint end) The two inner and outer side plates are disposed such that the bent portions of the inner and outer side plates are staggered so that the screw fastening coupler 150 is stiffened while the fastening structure is stably retained when fastened.
