This application claims priority to and the benefit of Korean Patent Application No. 2017-0017478, filed on Feb. 8, 2017, the disclosures of which are incorporated herein by reference in its entirety.
The present invention relates to a self-pouring mold system and a method of fire-proofing, repairing, and reinforcing using the same and, more specifically, to a self-pouring mold system allows uniformity of a fire-proofing material to be ensured by pouring concrete at a side of a mold installed at a wall structure and minimizing a fall head generated when the concrete is poured to prevent bleeding and ensure uniformity of a material, and allows adjusting a fire-proof covering to be constructed in a required fire-proof thickness.
Before a concrete wall C is built, molds are connected to a portion in which concrete is poured. The molds are connected by a conventional connection method and structure. At a side wall portion, a side wall contact part 3a of a side wall mold 3 is disposed toward a side of the concrete wall C.
At the same time, both connection surface parts 3c are disposed to adhere to sides of the molds 1. Fixing protrusions 5b of a plurality of fasteners 5 are inserted into fastening holes 1a of the mold 1, and grooves 5a of the fasteners 5 are disposed to surround the side wall mold 3 and sides of molds 1 adjacent to the side wall mold 3. A conventional wedge member is inserted into a wedge insertion groove 5c. The fasteners 5 are coupled to the molds so that the side wall mold 3 is coupled to the adjacent molds 1.
Therefore, concrete is poured into an inner space of the molds 1 and the side wall mold 3 to construct the concrete wall C, and the concrete is generally poured through upper openings of the molds. However, in some cases, the open upper portion is not used due to interference by an existing concrete structure.
Although as not shown, concrete is poured toward sides of molds. In this case, it is not easy to check whether the concrete is poured to be airtight by visual inspection, and it is not easy to manage the quality of the concrete because the concrete is poured toward the sides.
Therefore, pouring of concrete toward rear sides of the molds using the injection hole H is described, and it can be indirectly checked whether the concrete is practically poured to be airtight through an air outlet (not shown).
The mold construction is described based on a case in which a mold is installed in a tunnel cross-section shape, but a mold for a building wall is constructed the same way.
Therefore, when concrete is poured into a mold, whether the concrete is poured into the mold or toward a rear side of the mold to be airtight is checked, and then whether the concrete is evenly poured can be checked by checking whether bleeding of the poured concrete occurs, and thus, construction and quality management of a fire-proof covering for concrete is possible.
However, new quality management of concrete poured into an inside or toward a rear side of an existing mold, for example, quality management of poured concrete according to a pouring pressure, has not been introduced, but it is shown that quality of the concrete is managed by indirect construction management in the field (a method using an air outlet).

Also, a front panel block out part S3 is formed so that the whole front panel part 120 is coupled to a front of the mold frame part 110, and the front panel part 120 is formed to be inserted into the front panel block out part S3 of the the mold frame part 110 so that the front part of the mold frame part 110 is not stepped.
Also, a finishing plate-upper opening part S4 is formed so that a horizontal pouring finishing plate 210, which will be described below, is horizontally inserted between an upper side of the front panel part 120 and a lower side of an upper plate 114 of the mold frame part 110.
Therefore, the front panel part 120 is in direct contact with concrete poured toward the front panel part 120, and a concrete finishing surface is effectively formed.
Next, the front panel part 120 is made of steel, has an upper central vertical opening part S5 cut downward from an upper central portion thereof to communicate with the central vertical opening part S1, and has a smaller width than the central vertical opening part S1.

Therefore, as shown in
In this case, heights of the vertical guide units 220 are slightly greater than a height of the upper central vertical opening part S5 formed on the front panel part 120.
As shown in
As shown in
Therefore, the poured concrete does not leak toward the upper central vertical opening part S5 of the front panel part 120.
In this case, a height of the vertical pouring finishing plate 230 is formed to correspond to the height of the upper central vertical opening part S5 formed on above-described the front panel part 120.

As shown in
Therefore, the pouring pipe flange part 242 of the middle pouring pipe bracket 240 is in contact with a front side of the rear pouring pipe bracket 250 and is separated from the front side thereof, and the pouring pipe flange part 242 and the clamping fixture 252 are set to communicate with each other. As shown in
That is, as shown in
The holding groove 241 is formed in an upper side of the middle pouring pipe bracket 240, and the horizontal hook part 212 is horizontally inserted therein by the insertion holding parts 213 of the horizontal pouring finishing plate 210.
Referring to
As shown in
The pouring pipe 300 is connected to a concrete pumping apparatus 400 using an extension pipe member 410. The fastening fixture 310 is inserted into the pouring pipe 300 and is rotatably fastened to the clamping fixture 252 of the rear pouring pipe bracket 250.
[Method of Fire-Proofing, Repairing, and Reinforcing Using a Self-Pouring Mold System of an Embodiment of the Present Invention]
As shown in
Referring to 4A, it can be seen that the self-pouring apparatus 200 is initially set in the mold 100.
That is, the upper central vertical opening part S5 is exposed toward a front of the front panel part 120 as an opening, and the horizontal pouring finishing plate 210 set by the vertical guide units 220 of the self-pouring apparatus 200 protrudes from a lower end of the upper central vertical opening part S5.
Also, the vertical pouring finishing plate 230 of the self-pouring apparatus 200 is slightly separated from the front of the front panel part 120, and a front side of the pouring pipe 300 is exposed to an upper end of the vertical pouring finishing plate 230.
Therefore, the vertical guide units 220 are exposed to the rear side of the front panel part 120, and the horizontal hook part 212 of the horizontal pouring finishing plate 210 is exposed. The pouring pipe 300 is also exposed to pass through the middle pouring pipe bracket 240, the rear pouring pipe bracket 250, and the vertical pouring finishing plate 230.
Also, as shown in
The pouring pipe 300 is connected to the concrete pumping apparatus 400 by the extension pipe member 410.
Next, as shown in
That is, as shown in
Therefore, the lower side of the horizontal pouring finishing plate 210 rises due to a pouring pressure caused by continuously pouring the concrete, which is applied as a force that lifts the self-pouring apparatus 200.
In the present invention, self-pouring refers to concrete being poured toward the front side of the front panel part 120 while the self-pouring apparatus 200 rises due to the pouring pressure.
In this case, the pouring pipe 300 passes through the the horizontal pouring finishing plate 210, the vertical pouring finishing plate 230, the middle pouring pipe bracket 240, and the rear pouring pipe bracket 250 of the self-pouring apparatus 200 to be lifted together therewith.
Positions of the vertical pouring finishing plate 230, the middle pouring pipe bracket 240, and the rear pouring pipe bracket 250 are guided by the vertical guide units 220 and are lifted at the same time.
The horizontal pouring finishing plate 210 is bound by the holding grooves 231 and 241, the insertion holding parts 213, and the fixed holding part 214 and is placed on upper surfaces of the vertical pouring finishing plate 230, the middle pouring pipe bracket 240, and the rear pouring pipe bracket 250.
Therefore, the insertion holding parts 213 horizontally inserted into the holding grooves 231 and 241 have a triangular or inverted-triangular cross-section to be vertically bound to each other after the insertion holding parts 213 are horizontally inserted therein.
As shown in
As shown in
In this case, the horizontal pouring finishing plate 210 protrudes toward the front side of the mold 100 and is inserted into a rear side of the mold 100 so as not to protrude.
That is, as shown in
In this case, the vertical pouring finishing plate 230 is also inserted into the front panel block out part S3 formed on the front panel part 120 to be finished.
As shown in
That is, as shown in
When the concrete C rises, the pouring pressure is not uniformly applied to the horizontal pouring finishing plate 210, and an upper surface of the poured concrete is not even.
For example, as shown in
A pouring pressure of the pouring pressure adjustor 420 is adjusted to be less than a pouring pressure of concrete all the time, and another part that has tension instead of a spring may be used as the pouring pressure adjustor 420.
Also, the fixing plate 430 may further be installed under the pouring pipe 300 between the pouring pipe 300 and the reinforcing rib 130 to support the pouring pipe 300.
Therefore, when the self-pouring mold system A having the pouring pressure adjustor 420 is used, the pouring pipe installed to pass through the mold from the rear side of the mold to the front side thereof is lifted using a pouring pressure of concrete filled from the lower portion of the mold so that the upper surface of the mold is regularized to a pouring surface, and thus the concrete can be effectively poured. The concrete is evenly poured by determining whether the poured concrete bleeds, and when bleeding of the concrete hardly occurs, construction and quality management for a fire-proof covering of concrete is possible.
By using a self-pouring mold system of the embodiment of the present invention, quality management can be very easily performed because visual inspection is not necessary to check whether concrete is poured in a mold, construction can be effectively managed by easily finishing an upper surface after concrete is poured, concrete can be be effectively poured by being directly installed on a mold to be easily operated, whether poured concrete is poured to be airtight through a self-pouring mold system can be determined, and construction and quality management are possible for a fire-proof covering of concrete because the concrete is poured using a pouring pressure while the pouring pipe is vertically moved so that bleeding of concrete is hardly generated and concrete is evenly poured.
The above description is only exemplary, and it should be understood by those skilled in the art that the invention may be performed in other forms without changing the technological scope and essential features. Therefore, the above-described embodiments should be considered only as examples in all aspects and not for purposes of limitation. For example, each component described as a single component may be realized in a distributed manner, and similarly, components that are described as being distributed may be realized in a coupled manner.
The scope of the present invention is defined not by the detailed description but by the appended claims, and encompasses all modifications or alterations derived from the meanings, scope, and equivalents of the appended claims.
