Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a brick panel formed into a single panel by connecting individual bricks with a binding agent, and a method for manufacturing the same.

Generally, for brick-style buildings, the exterior method of covering ceramic brick tiles with cement mortar is popular for design reasons and to improve weather resistance. However, on the other hand, peeling of tiles due to earthquakes or poor construction is a problem, and installing tiles after a building is completed requires a large number of skilled workers and requires careful interior and exterior construction. There were other problems.

The present invention has been made in view of the above-mentioned points, and provides a brick panel in which individual bricks are firmly connected together using a solidifying agent such as an adhesive to form a single panel, and a method for manufacturing the same. This is the purpose.

Embodiments of the present invention will be described below based on the drawings. Reference numeral 1 in the figure is a brick panel, which is formed into a single plate by bonding and connecting the adjacent sides of a large number of individual bricks 2, that is, at the joints 3 with a binding agent 4. It is. This brick 2 is called a PS special brick, which has physical properties of compressive strength of 300 kg/cm ² or more and 24-hour static water absorption of 10% or less. Three holes 5 for muscle insertion are bored, but these holes 5 are not necessarily necessary and are provided as needed. In addition, the above-mentioned setting agent 4 is a setting agent 4 exclusively for the above-mentioned brick unit 2. In other words, the brick unit 2 with a water absorption rate of 10% or less is usually called a mortise brick, and this setting agent 4 takes advantage of the characteristics of the mortise brick. Consolidating agent 4 contains 5 parts of an admixture of one or more selected from styrene-butadiene rubber, vinylidene chloride, vinyl acetate, and vinyl chloride per 100 parts by weight of cement.
The mixture is mixed and dispersed in a proportion of ~50 parts by weight, and the required amounts of water, sand, and a high fluidity imparting agent are added thereto. Furthermore, the physical properties of this solidifying agent 4 are that conventional solidifying agents such as mortar have a compressive strength of 187.4 kg/cm ² and a bending strength of
The compressive strength is 468.9Kg/cm2 compared to 37.5Kg/ ^cm2 .
^cm2 , bending strength 103.6Kg/ ^cm2 , and freeze resistance, that is,
The strength decreases by about 1/4 in the freeze-thaw test (50 times), and the fire resistance is 1 hour and 40 minutes (1700℃).

Next, a method for manufacturing this brick panel will be described. Reference numeral 7 is a formwork, and a support plate 7a has a support surface that has good flatness accuracy and can maintain a horizontal surface.
and weir plates 6 erected around the four circumferences of the support plate 7a. This weir plate 6 is reliably and removably attached to a support plate 7a in accordance with the dimensions of the brick panel, and the weir plate 6a located on the left side in the figure is for example used to hold vertical reinforcing bars (not shown). , grooves 6b are bored to match these spacings and dimensions.
Next, a joint member 8 for forming the joint portion 3 is set within this formwork 7. In this case, single brick 2
It is best to use a standard joint width of 10 mm. This joint member 8 is used to determine the position of the brick unit 2 in advance, and is fixed to the surface of the support plate 7a with rubber or other suitable material. After that, the support plate 7a of the formwork 7
A reinforcing wire mesh 9 having the same shape as the formwork 7 is set on the upper surface of the mold. The reinforcing wire mesh 9 may be formed in advance into a mesh shape, or may be formed by combining a large number of bar meshes into a mesh shape.

Next, we proceed to placing the bricks 2 in the formwork 7 and filling the formwork 7 with the solidifying agent 4. In this case, there are two methods. One method is to set the reinforcing wire mesh 9 in the formwork 7, fill it with a hardening agent 4, and then arrange and line up the bricks 2 in accordance with the joint members 8. Another method is to set the reinforcing wire mesh 9 in the formwork 7, place the bricks 2 along the joint members 8, and then fill the cement 4. In the present invention, these two methods can be selected as appropriate depending on the work situation. In both methods, a release agent is applied to the surface of the support plate 7a in advance. Also, solidifying agent 4
Pour only the necessary amount considering the depth of the joint. In this way, a single brick 2 is placed inside the formwork 7.
After arranging and filling the solidifying agent 4, each mold 7 is cured until the solidifying agent 4 is sufficiently hardened and the product reaches sufficient strength. In this case, if the temperature is below 5°C or is likely to fall below 5°C, the product is covered with a sheet or the like until it reaches sufficient strength, and the above-mentioned curing etc. are performed as necessary. By carrying out this curing, the product will not suffer from poor hardening of the solidifying agent due to severe drying.

Next, after curing is completed, the weir plate 6 constituting the formwork 7 is removed, and the mold is demolded while standing up in the width direction together with the support plate 7a surface. The demolded brick panels are stood up in the width direction and stored in the demolded state. If it is unavoidable to move it from the demolding position, use a cloth belt to move it in a horizontally raised position. The brick panel stock stand shall have a structure that does not generate large stress on the brick panel.

The strength of the brick panel manufactured in this way is flexural strength 13.2 to 29.0 Kg/cm ² and elastic modulus 2.2×10 ⁵
~4.7×10 ⁵ Kg/cm ² , deflection ratio (ratio of deflection to span) 1/5841, environmental characteristics are thermal conductivity
Test results have revealed that it has a transmission loss of 0.53 kcal/m·h·deg and a transmission loss of 27 db to 63 db.

In the above embodiment, a case has been described in which the reinforcing wire mesh 9 is set in the formwork 7 and then the solidifying agent 4 is filled, but the reinforcing wire mesh does not necessarily have to be used.

According to the present invention, individual bricks are bonded together using a special binding agent, and the solidifying agent is used as a joint to form a single brick panel. Compared to the conventional method of covering brick tiles with cement mortar, this method improves the performance of external walls, such as heat insulation and weather resistance, and eliminates the need for exterior or interior construction. In addition, it is possible to perform complicated stacking methods without requiring external scaffolding during construction, which is the case with conventional exterior methods. Furthermore, by converting individual bricks into panels, on-site construction time can be shortened and production can be streamlined.

In addition, the brick itself has a water absorption rate of less than 10% and a compressive strength of more than 300Kg/cm ² , and since the brick itself was formed into a single brick panel bonded with a special cement, the adhesion of the brick itself It is possible to easily form a panel by just using the method, and to create a brick panel with good strength and performance.

Further, since the solidifying agent has extremely high fluidity, it is possible to fill the molding frame with the solidifying agent extremely uniformly, thereby making it possible to further strengthen the bond between the bricks.
