Abstract

The present invention relates to a self-pouring mold system which ensures uniformity of a material by laterally pouring concrete into a mold installed on a side of a wall structure and minimizing a fall head generated when the concrete is poured to prevent bleeding, thereby ensuring uniformity of a fire-proofing material and adjusting a required fire-proofing coating thickness, and a method of fire-proofing, repairing, and reinforcing using the same.

First claim

What is claimed is:

1. A method of repairing, and reinforcing concrete using a self-pouring mold system, the method comprising:
(a) providing a self-pouring mold system, wherein the self-pouring mold system includes a self-pouring mold apparatus and a pouring pipe,
wherein the self-pouring mold apparatus includes:
a horizontal pouring finishing plate including a horizontal finishing plate set to a front side of a mold, and a horizontal hook part extending from the horizontal finishing plate toward a rear side of the mold through a front panel block out part;
vertical guide units transversely separated from each other on the rear side of the mold so that the front panel block out part is positioned as an opening, and installed to extend vertically;
a vertical pouring finishing plate set to the front side of the mold to finish the front panel block out part so that the horizontal hook part is supported on an upper side thereof from the rear side of the mold, and formed so that the pouring pipe passes therethrough; and
a middle pouring pipe bracket positioned by the vertical guide units and set to be in contact with a rear side of the vertical pouring finishing plate so that the horizontal hook part is supported on the upper side of the mold from the rear side of the mold, and formed so that the pouring pipe passes therethrough;

(b) supplying the concrete to the pouring pipe by using a concrete pumping apparatus; and
(c) inserting the horizontal pouring finishing plate toward the rear side of the mold, wherein the concrete is poured toward the front side of the front panel part of the mold and rises, and the horizontal pouring finishing plate is lifted by a concrete pouring pressure.

2. The method of claim 1 , wherein the self-pouring mold apparatus includes:
the horizontal pouring finishing plate including the horizontal finishing plate set to the front side of the mold, and the horizontal hook part extending from the horizontal finishing plate toward the rear side of the mold through the front panel block out part;
the vertical guide units transversely separated from each other on the rear side of the mold so that the front panel block out part is positioned as the opening, and vertically extending;
the vertical pouring finishing plate set to the front side of the mold to finish the front panel block out part, formed so that the horizontal hook part is supported on an upper surface thereof from the rear side of the mold, and formed so that the pouring pipe passes therethrough; and
the middle pouring pipe bracket positioned by the vertical guide units and set to be in contact with the rear side of the vertical pouring finishing plate so that the horizontal hook part is supported on an upper surface thereof from the rear side of the mold, and formed so that the pouring pipe passes therethrough.

3. The method of claim 2 , wherein the self-pouring mold apparatus further includes a rear pouring pipe bracket whose position is restricted by the vertical guide units, and which is in contact with a rear side of the middle pouring pipe bracket, is formed so that the horizontal hook part is supported on a rear side of the mold, and is formed so that the pouring pipe passes therethrough,
wherein the horizontal hook part is set to be supported on upper surfaces of the vertical pouring finishing plate, the middle pouring pipe bracket, and the rear pouring pipe bracket, and
the vertical pouring finishing plate, the middle pouring pipe bracket, and the rear pouring pipe bracket are guided along the vertical guide units by the pouring pipe passing through the vertical pouring finishing plate, the middle pouring pipe bracket, and the rear pouring pipe bracket and are vertically moved at the same time.

4. The method of claim 2 , wherein the vertical guide units includes:
an upper vertical guide unit formed on an upper end of the vertical guide unit to accommodate the middle pouring pipe bracket and a rear pouring pipe bracket therein; and
a horizontal guide unit extending downward from a lower surface of the upper vertical guide unit to be inserted between the middle pouring pipe bracket and the rear pouring pipe bracket,
wherein an upper central vertical opening part is positioned to correspond to an upper side of a central vertical opening part of the mold frame part, is installed on both sides of reinforcing ribs facing each other and positioned in the middle of the mold frame part, and is formed between the vertical guide units.

5. The method of claim 2 , wherein the vertical pouring finishing plate has a vertical plate shape and includes a holding groove formed on an upper side thereof and a pouring pipe flange part protruding from a rear side thereof so that the pouring pipe passes therethrough, and is set to be attached to a vertical guide block out part of an upper central vertical opening part formed on the front panel part to be vertically moved, and
when the horizontal hook part is horizontally pulled toward a rear surface of the mold, the horizontal finishing plate is guided in a finishing plate-upper opening part of the front panel part by the holding groove to be horizontally inserted therein.

6. The method of claim 2 , wherein the middle pouring pipe bracket has a rectangular plate shape and includes a pouring pipe flange part protruding so that the pouring pipe passes therethrough and formed on a rear side of the middle pouring pipe bracket,
wherein the pouring pipe flange part is in contact with a front side of a rear pouring pipe bracket and is separated from the rear pouring pipe bracket so that horizontal guide units of the vertical guide units are inserted between the middle pouring pipe bracket and the rear pouring pipe bracket, and
a holding groove is formed on an upper surface of the middle pouring pipe bracket so that the horizontal hook part is horizontally inserted into an insertion holding part of the horizontal pouring finishing plate.

7. The method of claim 2 , wherein the pouring pipe is installed to pass through the rear pouring pipe bracket, the middle pouring pipe bracket, and the vertical pouring finishing plate, and binds the rear pouring pipe bracket, the middle pouring pipe bracket, and the vertical pouring finishing plate to vertically move with the rear pouring pipe bracket, the middle pouring pipe bracket, and the vertical pouring finishing plate.

8. The method of claim 3 , wherein the rear pouring pipe bracket does not have holding grooves on an upper surface thereof, and includes a clamping fixture that is separately formed on a rear side thereof to be fixedly fastened to the pouring pipe, allows a fastening fixture inserted into the pouring pipe to be rotatably fastened thereto, and protrudes so that the pouring pipe passes therethrough, and
wherein the middle pouring pipe bracket has a front side which is in contact with a pouring pipe flange part of the vertical pouring finishing plate, and has a pouring pipe flange part formed on a rear surface thereof and set to be in contact with a front side of the rear pouring pipe bracket.

9. A self-pouring mold system which allows a pouring pipe installed to pass through a mold from a rear side of the mold to a front side thereof to pour concrete from a lower portion of the mold so that the concrete is uniformly poured without bleeding, the self-pouring mold system comprising:
a self-pouring apparatus installed to pass through a front panel block out part formed on the mold;
a pouring pipe installed on a front side of the mold so that the concrete is poured through the self-pouring apparatus from the rear side of the mold; and
a concrete pumping apparatus installed using an extension pipe member,
wherein the mold includes a mold frame part including
