Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filler foam for concrete construction,

The present invention relates to a filler mold filling an empty space between dies. More specifically, the filler foam is tied to a mold and a wedge form adjacent to each other by a concrete pouring pressure, The present invention relates to a filler foam for constructing a concrete structure for constructing concrete concrete structures (such as beams, girders, slabs, and inners to which structures are connected), and a mold connection structure using the same.

The concrete structure is constructed by installing the reinforcing steel reinforcement, the formwork and the fitting material (the reinforcing material, the long filling material, etc.) according to the design of the building, and curing the concrete in the formwork.

In recent years, the aesthetic improvement of concrete buildings has resulted in the construction of buildings with creative design, and also the structure of buildings in each building is changing.

Therefore, it is impossible to construct a building using an existing form, and in such a case, a filler foam having a smaller size than the existing form is installed between the existing forms. For example, a filler foam is installed between the beams, between the beam form and the slab form, between the beam and the girder, and between the slab form.

The filler foam is configured to fit the structure of the building, for example, when it is used for the construction of a beam, the filler foam is composed of a wall which is raised on both sides in the longitudinal direction of the bottom portion. Since the filler foam has no structure in connection with the neighboring formwork, the spacing is maintained through the long filling that maintains the spacing of the walls and is installed through a separate support.

The filler foam (finishing plate, slab plywood) is used for the construction of slabs in all of the patent documents 1 and 2 (registered patent application No. 10-0819833, registered utility model No. 20-0378317) Therefore, when the concrete is poured, it is separated from the neighboring mold by the putting pressure when the concrete is poured. In order to prevent this, a long filling material (space retaining material) or a reinforcing material is used There is a problem that installation and demolding are complicated and air is lengthened.

Patent No. 10-0819833 Registration Utility Model No. 20-0378317

The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a filler foam which is not detached from a neighboring mold by a putting pressure when a concrete is poured without providing a long filler in a filler foam provided in a space between the molds, The present invention aims to provide a filler foam for use in the construction of a concrete structure for constructing concrete structures (beams, girders, etc.) and a formwork connection structure using the same.

The filler foam for constructing a concrete structure according to the present invention has a smaller size than neighboring formworks and is interposed between neighboring formworks so as to cover the spaces of the formworks to prevent concrete from leaking. And an inclined wedge portion formed in an inclined manner in a direction of being gathered toward the opposite side of the poured surface of the peripheral portion corresponding to the neighboring formwork among the peripheral portions of the placement surface and being wedgedly coupled to the formwork .

The filler foam for constructing a concrete structure according to the present invention is characterized in that it is a gait filler foam comprising a bottom portion, a pair of wall portions, and an inclined wedge portion formed on the bottom portion and the wall portion.

The filler foam for constructing a concrete structure according to the present invention comprises a bottom portion, a first wall portion that is erected on both sides of the bottom portion and connects with the beam form, a second wall portion extending from the first wall portion at a predetermined angle and connected to the girder formwork And a sloped wedge portion formed on the bottom portion and the first and second wall portions and connected to the girder formwork in a wedge manner.

According to the inventive filler foam for constructing a concrete structure and the formwork connection structure using the filler foam, the filler foam is installed in a wedge form between the formwork, and is separated from the formwork only through the connection structure with the formwork, So that it is possible to reduce the number of working hours and shorten the air due to the use of long settlement.

As shown in Fig. 1, the filler foam 10 for concrete building construction according to the present embodiment has a pair of wall side walls 11 and 12 which are respectively formed on both sides in the longitudinal direction of the bottom side placing surface 11 and the bottom side placing surface 11 2 and 3) formed on the outside of the pouring surface of the filler foam body and formed adjacent to the pillar foam body, Shaped wedge portion.

The floor side paved surface 11 and the wall side paved surface 12 may each have a flat surface on which the concrete is laid, and of course, it may be irregular depending on the structure of the building.

The bottom side mounting surface 11 and the wall side mounting surface 12 may form a direct mounting surface or may be used with a separate mounting plate attached thereto.

The inclined wedge portions 11a, 12a, and 13a are inclined in the direction of collecting each other at both ends in the width direction of the opposite side of the concrete installation side of the bottom side installation surface 11 and the wall side installation side surface 12, And a structure having a predetermined length along the inclination at the bottom side placing surface 11 and the wall side placing side 12 is formed.

Although the wedge-shaped wedge portions 11a, 12a and 13a are shown as a pair extending from the bottom-side placement surface 11 and the wall-side placement surface 12 in the figure, the wedge-shaped wedge portions 11a, 12a and 13a ). &Lt; / RTI >

The filler foam 10 having such a structure is made of aluminum and the like and is manufactured by a profile.

Grooves 11b, 12b, and 13b are formed on the form-facing surfaces of the wedge-shaped wedge portions 11a, 12a, and 13a. The protrusions formed on the molds 1 and 2 are coupled to the grooves 11b, 12b and 13b to increase the binding force with the molds 1 and 2.

It is preferable that the end portions of the dies 1 and 2 are formed with inclined support portions at the same angle as the inclined wedge portions 11a, 12a and 13a.

According to the present embodiment, when the molds 1 and 2 are used alone, the voids are formed between the molds 1 and 2 to prevent the concrete from being poured, the filler foam 10 of the present embodiment is molded into molds 1 and 2 ). The filler foam 10 can be installed at the end of one of the molds 1 and 2 between the molds 1 and 2 and is shown as an example between the molds 1 and 2 in the figure.

The molds 1 and 2 are mounted on the ground by means of a support so that the end portions of the molds 1 and 2 which are not adjacent to each other are set to coincide with the other molds (formwork for girders, wall molds, etc.). Therefore, a void space is formed between the molds 1 and 2.

When the filler foam 10 of the present embodiment is sandwiched between the molds 1 and 2, the inclined wedge portions 11a, 12a and 13a of the filler foam 10 are formed on the opposite faces of the molds 1 and 2 And are engaged with each other.

Even if the filler foam 10 is sandwiched between the molds 1 and 2, since the opposite faces of the molds 1 and 2 are spread outside the oblique wedge portions 11a, 12a and 13a, Are not released between the dies (1,2) due to the support of the dies (1,2).

When the concrete is placed in the molds 1 and 2, the concrete pouring pressure in the direction toward the outside is applied to the filler foam 10, and the filler foam 10 is subjected to a force that is caused to spread outward by the pouring pressure, (10) is kept in an installed state without being widened by the inclination of the inclined wedge portions (11a, 12a, 13a) or separated from the molds (1, 2).

When the molds (1,2) are demolded after the curing of the beams, the support base of the filler foam (10) is eliminated, so that the filler foam (10) is easily demoulded.
