Description

Formwork assembly {CONCRETE FORMING ASSEMBLY}

The present invention relates to a form assembly, and more specifically, to the concrete wall in which a plurality of ties are fixed by reinforcing the vertical support and the horizontal support on the outer wall surface of the formwork board made of a different material of inner, outer plate or single sheet. It relates to a slope type formwork board and an inner wall forming method using the same.

A building material such as a tie for installing a reinforcement plate is used at an end projecting outward of the formwork while being embedded in concrete that is poured between a plurality of formwork.

Conventionally, a process for forming a wall of a building is described schematically, after the plurality of formwork is spaced apart at regular intervals in the width direction and arranged upright along the longitudinal direction, the plurality of longitudinal supports and the horizontal support on the outer wall of the formwork. Place each to fix the tie. The predetermined upright wall can be completed by curing after pouring concrete into the space between the formwork.

After the upright wall is completed, remove the formwork, vertical support and horizontal support, and then finish the outer wall surface by plastering on the wall surface of the upright wall, and install insulation material on the inner wall surface.

This conventional technology has a problem in that the work after the completion of the wall to separate the formwork, plastering, gypsum board construction, insulation construction must be performed separately, a lot of labor is required, and a lot of work time and cost.

In the conventional formwork related technology, since the vertical support is held upright between the formwork and the horizontal support without fixing the vertical support, the support for the formwork is not properly performed when concrete is placed, and there is a risk of work defects and safety accidents. there was.

In addition, since the connection between the formwork is about to be connected by a wire or the like, there is a fear that the wall surface may not be smooth while the arrangement of the formwork becomes uneven.

Moreover, when the assembly was completed by supporting the inner and outer formwork with the horizontal support, there was a rectangular region on the corner region side of the formwork assembly which the horizontal support was not supported because of its short length or mismatch.

Support the first tie 40 to be penetrated through) or the rod 61 is mounted in the fixing groove 16 of the formwork board 10 to perform the combined function to connect the adjacent formwork board 10 do.

The multifunctional member 60 is formed with a fixing piece 62 fixed to the wall surface of the outer plate 12 at the outer ends of the pair of rod-shaped rod 61, the inner end of the rod 61 The fixing plate 63 is fixed to the wall surface of the inner plate member 11 is provided.

In the center of the fixing plate 63 of the multifunctional member 60, there is a seating recess 64 recessed downward to allow the first tie 40 to pass therethrough.

The auxiliary board 70 is formed of a double member like the die board 10 and is disposed at the upper end of the pair of die boards 10 connected by the multifunctional member 60 to close the fixing groove 16. Has the function.

The second tie 50 is penetrated between the locking pin 51 and the inner plate 11 of the second tie 50 to prevent the inner plate 11 from being damaged by the locking pin 51. After the locking pin 51 is caught, the spacer member 80 is arranged to be spaced apart from the inner plate member (11).

1, 4, and 7, the third tie 90 is disposed between both inner plate members 11. The third tie 90 is hung on each seating groove 64 of both fixing plates 63, respectively. The third tie 90 has locking grooves 91 formed at both ends thereof to allow the fixing plate 63 to be firmly supported by the inner plate member 11.

The third tie 90 is disposed below the first tie 40 and stacked side by side with the first tie 40 up and down, and both inner side plates 11 are formed at one side of the third tie 90. A fastening groove 92 is provided to bundle and fix the reinforcing bar 100 vertically disposed therebetween with the first tie 40 and the wire 110.

1 and 4, a support 120 is disposed on the bottom surface of the formwork board 10 and an adjacent outer surface thereof to support the bottom surface of the formwork board 10. Support 120 is located substantially along an area for forming a wall.

1 to 7, the inner wall forming method using the formwork assembly according to an embodiment of the present invention, first, a plurality of formwork boards 10 are arranged in a longitudinal direction in parallel for placing concrete in a predetermined interval in parallel After spacing, the bottom surface is supported by the support neck 120, and the plurality of longitudinal supports 20 are arranged on the outer surface at equal intervals.

At this time, the multi-function member 60 is mounted to the insertion grooves 15 on both sides of the formwork board 10 through the third tie 90.

Next, the plurality of first ties 40 between the formwork boards 10 pass through the first tie through holes 13 or are seated in the seating grooves 64 of the multifunctional member 60 so as to pass through the first ties. After passing through the groove 17 through the first tie through hole 21 of the vertical support 20, the wedge 45 is mounted to the wedge holes 42 of both ends thereof, and the vertical support 20 is mounted. Fix it.

In this state, after placing the plurality of horizontal supports 30 on the outer surface of the vertical support 20, the plurality of second ties 50 are moved to the outside of the outer plate 12 through the second tie through hole 14. After being exposed, the hook 55 hanging on the horizontal support 30 is connected to the wedge 56 to fix the horizontal support 30.
