Description

Concrete foam panel {CONCRETE FORM PANEL}

The present invention relates to a concrete foam panel in which gas holes are used for the construction of concrete structures, and to a concrete foam panel in the form of a general flat plate.

As is well known, concrete foam panels (commonly referred to as formwork) are assembled to partition an arbitrary space, and when concrete is poured and cured in any of these partitioned spaces, concrete structures are made of wood. This is mainly used, but it is impossible to recycle, the use of uncomfortable problems occurred.

Therefore, in recent years, the GMT (Glassfiber Metreinforced Thermoplastic) concrete foam panel, which is manufactured by injection molding of general resins, has been invented and is already in practical use. Such a GMT type concrete foam panel is recyclable, and compared with the wood concrete foam panel. It is convenient to use, but in order to maintain its own strength while preventing deformation, the thickness must be thickened, and reinforcing frames, etc., must be provided to reinforce the strength so that the weight of the worker increases and the labor load of the worker increases. There was this.

In order to solve this problem, a gas-injected concrete foam panel, which has been previously filed by the applicant as Korean Utility Model Application No. 98-18013, has recently been proposed, and thus, the resin foam concrete foam panel has a relatively smooth surface on its front surface. The rear surface is provided with a plurality of vertical ribs and horizontal ribs intersecting with each other by 90 degrees, and the edges protrude rearward, and the vertical ribs 15a, 15n, 15c, 15d, 15e, and 15f and the rear surfaces 11b, 12b, A reinforcing portion 14 ', 15' is formed at the boundary of 13b) and at the boundary of the edge 14 and the rear surfaces 11b, 12b, 13b, respectively, and inside the reinforcing portions 14 ', 15'. The hole 18 is formed, It is characterized by the above-mentioned. Even if the gas-injected concrete foam panel is formed with a thin resin of high strength, self-deformation is suppressed by the reinforcing portions 14 'and 15' having gas holes 18 formed at each boundary during cooling after molding. Compared with the conventional GMT-type concrete foam panel, its own weight is greatly reduced, thus reducing the labor load of the worker and eliminating the need for insert molding of a separate reinforcing material for strength reinforcement.

On the other hand, the Utility Model Application No. 98-18013 described as a concrete concrete panel 10 of the step form as an embodiment thereof, the concrete foam panel thereof is not limited to this embodiment, it is a general '-' type It can be applied to flat concrete foam panels.

The present invention is another embodiment of Utility Model Application No. 98-18013 as mentioned above, by forming a general '-' type of resin foam concrete foam panel by gas injection, and the boundary between the vertical ribs and the rear Reinforcing portions are formed at the borders and the borders of the rear, respectively, and the gas holes are formed in the reinforcing portions, but an object thereof is to provide a concrete foam panel in which sufficient strength is maintained.

The present invention for achieving the above object, the front surface is formed of a relatively smooth surface, the rear is provided with a plurality of vertical ribs and horizontal ribs intersecting with each other 90 degrees, the edge is projected to the rear, vertical ribs and rear In the '-' type concrete foam panel in which a boundary of the vertical border and a boundary of each vertical border and the rear surface are formed, and a gas hole is formed inside the reinforcing portion, the vertical edge and the vertical rib and the horizontal rib are partitioned. Each side is provided with a plurality of reinforcing horizontal ribs, respectively, and the four corners divided by vertical / horizontal edges and vertical ribs and horizontal ribs are provided with a plurality of reinforcing horizontal ribs and inclined ribs, respectively. It is structured.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 4, the concrete foam panel 10 according to the present invention, the front surface 11 is formed of a relatively smooth surface, the rear surface 12 has a plurality of vertical ribs 15 and horizontally intersected with each other by 90 degrees Ribs 16 and edges 13 and 14 are provided to protrude rearward, and reinforce the boundary portions of the vertical ribs 15 and the rear surface 12 and the boundary portions of the vertical edges 13 and the rear surface 12, respectively. The portions 13 ', 15' are formed, and the gas holes 24 are formed inside the reinforcing portions 13 ', 15'. Further, both side portions 19a partitioned by the vertical rim 13 and the vertical rib 15 and the horizontal rib 16 are each provided with a plurality of reinforcing horizontal ribs 17, in particular the vertical / horizontal rim 13 The four corner ribs 19b partitioned by the fourteen ribs 14 and the vertical ribs 15 and the horizontal ribs 16 are provided with a plurality of reinforcing horizontal ribs 17 and inclined ribs 18, respectively. Are provided with a plurality of reinforcing horizontal ribs 17 and inclined ribs 18, respectively, and both side portions 19a and edge portions 19b are reinforced. Therefore, even if the total thickness of each component of the concrete foam panel 10 can be made thin, it is possible to sufficiently support the external force applied during the casting / curing of concrete.

Referring to the molding operation of the concrete foam panel 10 schematically, a liquid resin having strength reinforced in the mold is injected, gas is injected, and then cooled to cool the gas into the reinforcement parts 13 ′ and 15 ′. In order to form the holes 24, the gas holes 24 are formed by injecting gas into these reinforcement parts 13 'and 15', thereby providing a plurality of gas injectors in the molding apparatus of the concrete foam panel. The gas holes 24 can be formed in each of the reinforcement parts 13 'and 15' by injecting gas in a state where the two gas injectors are arranged at the positions of the one reinforcement parts 13 'and 15'. In this case, a number of gas injectors are required, which increases the number of parts of a device for forming a concrete foam panel.

Accordingly, as shown in FIG. 1, main gas lines 20 and 21 disposed parallel to the horizontal ribs 16 are formed on the rear surface 12 at approximately center positions of the entire longitudinal length, but are divided into two lines. And the gas inlets 20a and 21a are formed separately at approximately mid positions of the respective main gas lines 20 and 21, and the gas holes 24 of the main gas lines 20 and 21 (see FIG. 5). In the case where the gas holes 24 of the reinforcing portions 13 'and 15' communicate with each other, the concrete foam panel 10 can be appropriately formed by only two gas injectors. That is, after injecting liquid (heated) resin into the mold forming the concrete foam panel, gas is injected into the respective injection units 20a and 21a through two gas injectors. The gas injected through the injection parts 20a and 21a is formed such that the gas holes 24 of the main gas lines 20 and 21 and the gas holes 24 of the reinforcement parts 13 ′ and 15 ′ communicate with each other. .

On the other hand, when the main gas line is formed in one line similar to the concrete foam panel of Utility Model Application No. 98-18013, since only one gas injector is required, Although the number of parts is further reduced, gas injection is not performed smoothly, and the time required for gas injection is increased, resulting in a problem that productivity is lowered. In detail, the stepped concrete foam panel of Utility Model Application No. 98-18013 has a large external force at the time of placing / curing concrete, so the size thereof can be limited so much that only one gas injector is used to supply gas. Even if injected, gas injection is made smoothly.

However, since the '-' type concrete foam panel 10 according to the present invention has a smaller external force applied during pouring / curing of concrete than the stepped concrete foam panel, it is larger than the size of the stepped concrete foam panel, approximately 600 × 1200 cm It is common to be manufactured and used to such a degree, and in this case, only one gas injector does not perform gas injection smoothly, which causes a problem of greatly increasing a defective rate.

In addition, when the overall size of the concrete foam panel is larger than the main gas line is divided into three or more lines, each gas line by forming a gas inlet to facilitate the gas injection, but the concrete foam panel It is not preferable when considering the material problem of the material, or the magnitude of external force applied to the concrete foam panel during concrete pouring / curing.

According to FIG. 1, the vertical ribs 15 are formed on the rear surface 12 between the vertical ribs 15 partitioned by the vertical ribs 15 arranged at the center of the horizontal length of the concrete foam panel 10. A plurality of connecting ribs 22 are provided so that the guide grooves 22a are formed at substantially central portions of the horizontal ribs 16 disposed therebetween, and the vertical ribs 15 are interconnected with the connecting ribs 22. ) Is provided with a reinforcement vertical rib 23 arranged in parallel. When forming a plurality of connecting ribs 22 and the reinforcement vertical ribs 23 as described above, it is possible to directly connect a pair of concrete foam panels 10 installed to face each other for placing / curing concrete. This will be described below in detail with reference to FIG. 6.

6 is a view showing the interconnection state between the concrete foam panels according to the present invention, according to the pipe-shaped guide between a pair of concrete foam panels 10 arranged so that the front face 11 is facing each other After installing the member 30, but through the guide groove 22a of any connecting rib 22, the guide member 22a and the pierced guide grooves 22a of the pair of concrete foam panels 10 facing each other. It arrange | positions so that the inner hole of 30 may communicate. Thereafter, the connecting pipe 31 having the anchor bolts 32 at both ends is inserted into the communicating hole, so that the anchor bolts 32 fixed at both ends of the connecting pipe 31 are connected to each of the concrete foam panels 10. Protruding in the direction of the rear surface 12, inserting the washer 34 and the nut 35 to each anchor bolt 32, and then torque the nut 35 to the rib of each concrete foam panel 10 ( 15, 16) A pair of transverse support pipes 33 are fixed to the outer surface. Here, the guide member 30 guides the connecting pipe 31 to pass through / inserts into the guide groove 22a of the opposed concrete foam panel 10, and serves to secure a casting / curing space of the concrete. The transverse support pipe 33 serves to prevent the concrete foam panels 10 which are arranged in the transverse direction and are connected to each other by being pushed out by an external force (by concrete weight) applied during concrete placing / curing. In addition, the connecting rib 22 visually guides the hole processing position for inserting the connecting pipe 31, together with the reinforcing vertical ribs 23, the connecting members 30, 31, 32, 33, 34 and 35. It serves to prevent the concrete foam panel 10 is deformed or broken by the fastening through the medium.
