Description

Non-combustible exterior wall panel and its construction method {Architectural panel for outer wall and construction process of the same}

The present invention relates to a non-combustible exterior wall panel and a method of constructing the same, and more specifically, to a non-combustible exterior wall panel and a construction method thereof, which consists of a panel portion and an exterior portion, and wherein the panel portion and the exterior portion are formed of a non-combustible material, thereby forming an exterior wall of a building without having a separate fire response test report. It relates to a non-combustible exterior wall panel and its construction method that eliminates the burden of the period and cost for obtaining test results by allowing construction to take place, thereby shortening the construction period of the exterior wall, reducing costs, and obtaining fire response. .

In general, the base surface of the concrete wall, brick wall, or steel stud (hereinafter referred to as 'exterior wall') that constitutes a building is equipped with exterior wall panels of various materials to prevent the infiltration of rainwater and etc. and to decorate the beautiful exterior. Construction is done.

As an example of a conventional exterior wall panel, it is made of non-metallic or metallic sheets such as aluminum, hot-dip galvanized steel sheets, and stainless steel sheets, which are expensive for the materials used and finishing treatments as the finishing process is heat-treated after painting or treated in a chemical precipitation tank. Not only does it cost a lot of money, it also has the problem of not being able to apply various finishing materials, and it is not eco-friendly due to the emission of various pollutants.

Another example is the Dry Beat method, which involves placing a foamed styrene-based insulation board on the exterior wall of a building, that is, the base, attaching a mesh made of glass fiber, and then treating it with an external finishing material. However, this method has the problem of being vulnerable to fire.

In fact, as a fire occurred in a high-rise building in Haeundae, Busan in 2010 and the fire spread through exterior materials, people became aware of the risk of exterior wall fires caused by aluminum composite panels and dry bits, and in 2015, an apartment fire in Uijeongbu, Gyeonggi-do occurred on the first floor of a piloti structure. A fire that occurred in a parking lot was connected to the flammable exterior wall finishing material of the Dryvit method, and the flame spread rapidly. When a fire broke out, the fire spread due to the finishing material of the building. In the wake of the Jecheon Fire in 2017, there was a need to improve related systems for exterior finishing materials, etc. The demand for it is increasing.

In the event of a fire in a building, priority is given to suppressing the spread of the initial flame in order to reduce damage to life and property. Measures to prevent the spread of fire include securing the fire resistance of structural members in the fire compartment and restricting the use of finishing materials according to their combustion performance. etc. are also being done. In addition, mitigation policies were mainly aimed at securing economic feasibility from an industrial perspective, such as reducing construction costs and shortening construction periods, but now, it is necessary to consider ensuring safe residence for users and contributing to the environment through reduction of unnecessary energy use. Therefore, although insulation materials have recently been focused on building law and environmental law issues, regulations on building fire safety, building energy reduction, pollutant emission limits, and waste disposal are also strengthening. In other words, it is more effective to prevent a fire in advance than to respond to it after it has occurred in a building, so use semi-non-combustible materials to prevent or delay the spread of fire. Accordingly, if the building's finishing materials are non-combustible, a separate test report is not required, but if the finishing material of the building is semi-non-combustible, a test report proving fire safety is required.

Therefore, the finishing materials of the building, that is, the panel parts and plastering parts that make up the exterior wall panel, are made of noncombustible materials, preventing additional time and costs for obtaining test results, and providing safety against fire. development is on the rise.

<First embodiment>

As shown in FIGS. 1 to 4, the non-combustible exterior wall panel of the first embodiment consists of a panel portion 10 and an exterior portion 20, and the panel portion 10 and the exterior portion 20 are made of non-combustible materials. By allowing the construction of the exterior wall of a building to be carried out without the need for a separate fire response test report, the burden of the period and cost for obtaining the test score is eliminated, thereby shortening the construction period of the exterior wall, reducing costs, and reducing fire damage. Achieve responsiveness.

The panel portion 10 functions to form a base surface so that the exterior portion 20 can remain stably fixed.

The panel unit 10 includes a board 110 and a fixing bracket 120.

The board 110 is formed in the form of a plate of a certain thickness and supports the external wall of the building to be flattened.

The board 110 is a cement board mainly made of cement.

In this case, the board 110 includes 60 to 70 parts by weight of cement, 20 to 25 parts by weight of filler, 10 to 15 parts by weight of tensile reinforcement, 1 to 2 parts by weight of defoaming agent, and 1 to 2 parts by weight of curing accelerator. , 1 to 2 parts by weight of a water reducing agent, 0.5 to 1 part by weight of hydrogen peroxide, 0.5 to 1 part by weight of calcium stearate, and 0.1 to 0.5 parts by weight of a retardant.

Cement, as a base material, is classified into basic cement that hardens in air, hydraulic cement that hardens in air and water, and special cement. Here, Portland cement is the hydraulic cement.

Fillers improve strength and increase the surface area to increase the thickening effect.

The filler is a mixture of calcium carbonate and charcoal at a weight ratio of 1:0.2 to 0.3. Of course, it is not limited to this, and the filler may be calcium carbonate or charcoal alone. In this case, if it is less than 20 parts by weight, strength improvement and thickening effects cannot be expected, and if it exceeds 25 parts by weight, it affects the content of other compositions.

The tensile reinforcement improves the tensile strength and flexural strength of the board 110, thereby improving responsiveness to the behavior acting on the building.

The tensile reinforcement is glass fiber. Glass fiber is made by melting or processing glass containing silicate as a main ingredient into a fiber shape. It is divided into short fibers and long fibers, and here it is long fiber glass fiber. In addition, the glass fibers are formed to a length of 7 to 11 mm, maintaining mutual entanglement within the board 110 to improve the tensile strength and bending strength of the board. In this case, if it is less than 10 parts by weight, the required tensile strength or flexural strength cannot be maintained, and if it exceeds 15 parts by weight, smooth mixing cannot be obtained as it interferes with the mixing of other compositions.

The antifoam agent supports the bubbles generated during mixing to be stabilized and evenly dispersed. The antifoaming agent is hydroxyethyl cellulose.

Hardening accelerator promotes hardening of cement at room temperature. The curing accelerator is ammonium phosphate. In this case, if it is less than 1 part by weight, it is difficult to secure high initial strength, and if it exceeds 2 parts by weight, sufficient mixing time cannot be secured.

A superplasticizer is an admixture that improves strength and durability by reducing the amount of water required when kneading the mixture and promoting coagulation. As is well known, a polycarboxylic acid-based, melamine-based, aminosulfonic acid-based or naphthalene-based water reducing agent can be used.

Hydrogen peroxide is mixed with cement to generate bubbles, thereby reducing the weight of the board 110. In this case, if the amount is less than 0.5 parts by weight, the effect of generating bubbles is minimal, and if it exceeds 1 part by weight, there is almost no effect due to the increase in hydrogen peroxide.

Calcium stearate is a water-repellent material that prevents water from penetrating into cement pores. If it is less than 0.5 parts by weight, the water-repellent effect is minimal. If it exceeds 1 part by weight, water-repellent properties are good, but it interferes with mixing with water, which reduces workability. It deteriorates.

Retardants inhibit the hydration reaction of cement and delay the setting of cement. The retardant is citric acid. In this case, if it is less than 0.1 parts by weight, the delay effect is minimal, and if it exceeds 0.5 parts by weight, mixing with other compositions is hindered and the physical properties are lowered.

The composition of the board 110 prepared as described above is mixed, water is added, and kneaded. The amount of water is 40 to 50 parts by weight per 100 parts by weight of the composition. Then, the formed dough is put into a mold of a certain shape and cured at room temperature for a certain period of time. When the curing is completed, the mold is removed to obtain a board 110 of a certain shape.

The fixing brackets 120 are installed at both ends, that is, at the top and bottom of the board 110 based on the construction state, and support the exterior wall panel to maintain a firm fixation to the base surface (W), which is the exterior wall of the building.

The fixing bracket 120 consists of an upper bracket 122 and a lower bracket 124.

The top bracket 122 is configured at the top of the board 110 to maintain the top portion of the board 110 firmly fixed to the base surface (W).

The top bracket 122 has a first seating surface 1222 formed in close contact with the front top of the board 110, and the end of the first seating surface 1222 is bent as much as the thickness of the board 110. A first bent surface 1224 in close contact with the upper surface of (110), and a contact surface 1226 in close contact with the base surface (W) by bending a certain length upward from the end of the first bent surface 1224. is formed by

The bottom bracket 124 has a second seating surface 1242 formed in close contact with the front bottom of the board 110, and the end of the second seating surface 1242 is bent as much as the thickness of the board 110. It is formed as a second bent surface 1244 that is in close contact with the bottom surface of (110).

In this case, the bottom bracket 124 is formed at the bottom of the board 120 to prevent damage such as cracking of the bottom surface during storage or movement of the board 110. In addition, the lower bracket 124 is maintained to be stably seated on the upper bracket 122 of the fixing bracket 120 of the neighboring exterior wall panel located below. In some cases, the fixing bracket 120 is made of metal, and the upper and lower fixing brackets 120 stacked adjacent to each other are fixed to each other by welding, so that the outer wall is stacked in the upper and lower vertical directions on the base surface (W). It is also possible to improve the holding power of the panel. In some cases, the bottom bracket 124 may be omitted.

Additionally, the fixing bracket 120 remains fixed to the top and bottom of the board 110, respectively.

For example, as shown in FIG. 3A, a certain amount of adhesive is applied to the rear of the first seating surface 1222 of the upper bracket 122 and the rear of the second seating surface 1242 of the lower bracket 124 to secure the board 110. ) The fixing brackets 120 are fixed to the upper and lower ends of each using an adhesive method.

In this case, the adhesive is made of a non-combustible material. For example, the adhesive is mineral wool adhesive, etc.

Or, as shown in Figure 3b, a fixing means 130, for example, a direct screw, a fixing nail, It is configured to drive nails, etc., so that the fixing brackets 120 are fastened to the upper and lower ends of the board 110, respectively.

In this case, the fixing bracket 120 may be fixed to the board 110 by using the above-described adhesive and fastening methods in parallel.

The exterior portion 20 is formed on the front of the panel portion 10 to provide an attractive appearance to the building. In this case, the exterior part 20 is constructed using a mosaic method such as a masonry wall or a tile wall shape. Of course, it is not limited to this, and the exterior part 20 can be any material that is non-combustible and used to finish the exterior wall of a building. Here, for convenience of explanation, the shape of a masonry wall is shown.

The exterior portion 20 includes an exterior block 210, a finishing exterior block 220, and a stripe 230.

The exterior block 210 is formed on the front of the panel portion 10 and is formed to have a mosaic feel. For example, the exterior block 210 uses bricks, tiles, or clay that are actually used. In this case, in the case of actual bricks, it is formed at a thickness ratio of 0.2 to 0.5 with respect to the thickness of the actual brick, thereby reducing the weight of the exterior wall panel. Let it be lowered.

In addition, the exterior block 210 is fixed to the board 110 of the panel unit 10 using a mineral wool adhesive or fixing means, or by using these in parallel.

The finishing exterior block 220 is located at the end of the board 110, and maintains a natural mosaic feel by eliminating the formation of joint lines at the end joints when multiple exterior wall panels are stacked. In this case, the finished exterior block 220 is formed of the same or similar material and thickness as the exterior block 210. Of course, in some cases, the finishing exterior block 220 may be omitted and the exterior blocks 210 may be arranged on the board 110 in a mosaic manner to shorten the construction time of the exterior wall panel.

Meanwhile, the exterior block 210 and the finishing exterior block 220 may be formed in the same composition as the board 110 described above.

The bridging 230 performs bridging between the exterior block 210 and the finishing exterior block 220 attached to the board 110. In this case, the bridging work 230 is not a bridging block formed of synthetic resin as in the past, but is made of a non-combustible material such as cement, mortar, clay, etc. between the exterior block 210 and the finished exterior block 220.

The construction method using the non-combustible exterior wall panel constructed as above is as follows.

As shown in Figure 5, the construction method of the non-combustible exterior wall panel includes a base surface preparation step (S1), a non-combustible exterior wall panel attaching step (S2), a finishing exterior block attachment step (S3), and a rope forming step (S4). ), including.

The base surface cleaning step (S1) is a step of removing and leveling foreign substances remaining on the base surface, which is the exterior wall of the building. In other words, leveling work is performed on the base surface (W), which is the outer wall of the building, by removing or supplementing foreign substances, laitance, or fines remaining on the base surface (W). Additionally, a primer may be applied to the base surface to make the base surface water-repellent or waterproof.

As shown in FIG. 5B, the non-combustible exterior wall panel attachment step (S2) is a step of laminating and fixing the pre-manufactured non-combustible exterior wall panels on the substrate once the substrate preparation step (S1) is completed.

This is done by applying an adhesive made of a non-combustible material, such as a mineral wool adhesive, to the back of the non-combustible exterior wall panel and then adhering it to the base surface (W) so that the non-combustible exterior wall panel is fixed by adhesion. Next, the fixing means 130 is forcibly driven into the upper bracket 122 of the fixing bracket 120 formed on the top of the attached non-combustible exterior wall panel, so that the non-combustible exterior wall panel is firmly fixed to the base surface (W). In this case, as shown in Figure 4b, the fixing means 130 is forcibly inserted into the space between the exterior blocks 210 attached to the board 110 of the non-combustible exterior wall panel, thereby attaching the non-combustible exterior wall panel to the base surface W. Ensure that a firm fixing force is applied.

Meanwhile, the non-combustible exterior wall panel has an exterior block 210 attached to the board 110, as shown in FIG. 4b, and the finished exterior block 220 is attached through a process described later, so that it has a natural mosaic feel. Complete the exterior wall of the building.

As shown in Figure 5c, the finishing exterior block attachment step (S3) involves attaching the finishing exterior block to the board of the attached noncombustible exterior wall panel when the attachment of the noncombustible exterior wall panel to the background is completed through the noncombustible exterior wall panel attachment step (S2). It's a step. That is, when the non-combustible exterior wall panel is attached to the base surface (W), the finishing exterior panel 220 is attached to the space formed at the joint of the adjacent non-combustible exterior wall panels, thereby completing the mosaic-like exterior wall.

Accordingly, if a number of non-combustible exterior wall panels are simply attached, there is a problem of providing a heterogeneous texture as joint lines are formed at the joints of the non-combustible exterior wall panels. However, by constructing the finishing exterior block 220 through a separate process as described above, , It provides a natural mosaic-like appearance with no seam lines.

In the tie forming step (S4), when the attachment of the finishing exterior block is completed in the space formed at the joint of a plurality of non-combustible exterior wall panels through the finishing exterior block attachment step (S3), the attachment is completed in the space between the exterior block and the finishing exterior block. This is the stage where work is performed. In other words, rather than inserting an exterior block into a brick block made of synthetic resin as in the past, a bridge work is performed in the space between the exterior block 210 and the finished exterior block 220 using non-combustible materials such as cement, mortar, clay, etc. .
