Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an acoustic brick panel and a method of manufacturing the same.

This sound-absorbing brick panel refers to a unit sound-absorbing wall that is used to construct a sound-absorbing wall by extending it over a base material, and is unique in that it is made of sound-absorbing bricks.

Conventionally, such unit sound-absorbing tension walls did not exist.
Therefore, a sound-absorbing wall using bricks consists of a sound-absorbing material wall and a brick screen serving as a protective screen for the sound-absorbing material wall. That is, as shown in FIG. 1, for example, in front of a sound absorbing material wall A made of a sound absorbing material such as glass wool, rock wool, wood, fiber, etc.
It was constructed by stacking general-purpose bricks 1 in a grid pattern and erecting a brick screen S as a protective screen. Note that 2 is the frame wall.

In this sound-absorbing wall, the brick screen S itself acts as a protective screen for the sound-absorbing material wall A, and at the same time, the gap g in the meshwork is a net (opening).
Together with the sound absorbing material wall A behind it, it forms a resonant sound absorbing structure.

FIG. 2 shows another conventional example.

This is an example of a sound absorbing wall constructed by stacking perforated bricks 3 with through holes 3a in front of a sound absorbing material wall A alternately with general purpose bricks 1 at the broken joints, and erecting a brick screen S. . In the case of this sound absorption wall as well, the through holes 3a of the perforated bricks 3 in the brick screen S
becomes the netsuku (opening), and the sound absorbing material wall A behind it
Together with forming a resonant sound-absorbing structure, the sound-absorbing material wall A serves to promote the sound-absorbing effect.

Such conventional sound-absorbing walls have a structure that exhibits the sound-absorbing wall function by combining a brick screen S with openings (openings) and a sound-absorbing wall A behind it. During construction, a sound-absorbing wall A was created as an independent wall,
In front of it is a brick screen S, which is also an independent wall.
It is necessary to accumulate. In other words, two walls A,
S must be started up in parallel.

Therefore, firstly, the construction efficiency is poor, and secondly, there are limits to the height and strength of the brick screen S, and the accuracy of the assembling is also possible depending on the skill or proficiency level since it is done on-site. There was a problem in that the results varied.

This invention was made by focusing on these conventional problems, and its purpose is to arrange reinforcing bars in the mortar joints of sound-absorbing bricks that have been laid out in advance, and to attach them to the base material. A sound-absorbing brick panel comprising a first mounting jig and a second mounting jig buried therein (hereinafter referred to as the first invention).
and a manufacturing method thereof (hereinafter referred to as the second invention).

Hereinafter, this invention will be explained based on the drawings.

First, the first invention will be explained with reference to FIGS. 3 to 7.

3 is a perspective view showing an embodiment of the sound-absorbing brick panel according to the present invention, FIG. 4 is a cross-sectional view of FIG. 3, FIG. 5 is a cross-sectional view of FIG. 3, and FIGS. 6 and 7 are It is a perspective view of the parts which constitute the above-mentioned acoustic brick panel.

First, to explain the structure, the sound-absorbing brick panel P according to the first invention consists of sound-absorbing bricks B laid out in a rectangular manner on the same plane, and vertical and horizontal joints formed by these sound-absorbing bricks B. 1, the first mounting jig R and the second mounting jig F arranged at the same joint part 1, and these jigs R,
The joint mortar M is formed by filling the joint portion 1 in which the reinforcing bars S are arranged and the sound-absorbing bricks B are arranged and integrally bonded to the sound absorbing bricks B.

The sound-absorbing brick B here is formed by providing a rectangular opening h on the front side and fitting a sound-absorbing material k that closes the opening h from the back side into a recess on the back side. In this case, the sound absorbing material k is formed in advance into a rectangular parallelepiped.

The reinforcing bars S are usually steel rods with a diameter of 4 to 6 mm, and are connected vertically and horizontally along the joints of the joints 1.

The first mounting jig R consists of an anchor part 4 and a screw fixing part 5, as shown in FIG. The former 4 has a hook 4a formed by bending its base so that it cannot easily come out when buried in joint mortar M, and the latter 5 has a screw hole 5a. This jig R has its anchor part 4 arranged in the joint part 1, and is made to protrude from the outer surface of the sound-absorbing brick B to which the screw fixing part 5 is assigned. The amount of protrusion is set to correspond to the joint width between each panel P when the sound absorbing brick panels P are stretched as described below.

This first mounting jig R is assembled by inserting a self-tapping screw 12 into the screw hole 5a of the screw fixing part 5 (see FIGS. 8 and 9) and screwing it into the rim 9, which is the base material. This is hardware for installing the sound-absorbing brick panel P on the base material by inserting it into the base material.

As shown in FIG. 7, the second mounting jig F is bent into a U-shape and consists of an anchor part 6 and a fitting part 7. The former 6 is a part disposed in the joint part 1 and buried in the filled joint mortar M, and the latter 7 is formed into two prongs and protrudes from the back surface of the laid out sound-absorbing brick. This jig F has its fitting part 7 facing toward the rear surface of the sound-absorbing brick B and is arranged parallel thereto, and its opening 7a is also placed on the outer side surface of the sound-absorbing brick B in the left-right direction. It is placed towards.

This second mounting jig F has its fitting portion 7 connected to a rim 9 which is a base material, as will be described later (FIGS. 8 and 9).
By fitting the fitted part, that is, the angle plate 10 attached to the sound absorbing brick panel P
This is a jig for attaching the material to the base material.

The joint mortar M is a so-called resin mortar.

Although not shown, the sound-absorbing bricks B may have round openings h or relatively small openings, and may be provided in large numbers. Furthermore, a sound-absorbing brick may be used, which is formed by providing an inner cavity in the brick, making a large number or a small number of holes communicating from the inner cavity to the outside, and filling the inner cavity with a sound-absorbing material.

The arrangement of the sound-absorbing bricks B is not limited to the potato joint method of the embodiment, but other commonly used joint methods can be adopted as necessary.

If the first mounting jig R and the second mounting jig F are both attached by welding to the reinforcing bars S, the mounting strength can be further increased. The fitting portion 7 of the second mounting jig F is bifurcated, and for example, the fitting portion 7 described later, that is, the angle plate 1
0 (FIG. 8) is formed into two forks, it may be formed from one rod or one plate. The first mounting jig R and the second mounting jig F may be mounted at the vertical joint portion 1.
In this case, the screw fixing parts 5 of the first mounting jig R are made to protrude from the upper and lower outer surfaces of the allocated sound-absorbing bricks B,
Further, the opening 7a of the fitting part 7 of the second mounting jig F is directed downward so that it can be fitted from above into, for example, an angle plate 10 (FIG. 8) which is a fitted part of the body rim 9, which will be described later. .

With this configuration, when installing the sound-absorbing brick panel P on the base material, for example, as shown in FIGS. 8 and 9, the fitting part 7 of the second mounting jig F is attached to the base material A fitted part provided on the furring 9 which is a material,
That is, after fitting it into the angle plate 10, the lower end of the sound-absorbing brick panel P is placed on the panel receiver 11 attached to the rim 9, and then the first mounting jig R
A self-tapping screw 12 is inserted into the screw hole 5a of the screw fixing portion 5, and screwed into the furring 9 and tightened. A cushioning material 1 is placed between the sound-absorbing brick panel P and the rim 9.
3 to improve the fit.

In this way, the panels P are stretched one after another, and a back-up material 15 is inserted into the joints 14 formed between each panel P, and putty sealing 16 or mortar filling is applied. In addition, 17 is a frame wall, 18 is a baseboard, and 19 is a baseboard support.

As explained above, in the sound-absorbing brick panel according to the first invention, reinforcing bars are arranged at the joints of the sound-absorbing bricks arranged with a certain joint thickness, and the first mounting jig and the second mounting jig are installed at the same joints. In addition to arranging the jigs, mortar is filled in the joint portion where the reinforcing bars are arranged, and the allocated sound absorbing bricks are integrally connected. The following effects can be obtained.

(1) The required sound-absorbing brick panels can be manufactured in advance at a factory, and the panels themselves function as a complete sound-absorbing wall, so all you have to do is attach them to the base material of the frame according to the panel layout. , it is possible to create a desired sound-absorbing wall. Therefore, it is no longer necessary to erect two walls, a sound-absorbing material wall and a brick screen, as in the past, and the construction efficiency of the sound-absorbing wall can be improved.

(2) The strength of the sound-absorbing brick panel itself is high;
The strength of the sound absorbing wall formed by stretching this structure also increases. Therefore, unlike in the past, there is no restriction on the height of stacking, and there are no problems with strength.

Next, the second invention will be explained.

10 to 13 are diagrams for explaining the second invention. Components that are the same as those in FIGS. 3 to 9 are designated by the same reference numerals, and their explanations will be omitted.

First, to explain the structure, the method for manufacturing a sound-absorbing brick panel according to the second invention consists of the following nine steps. In other words, (1) Determine the external dimensions of the acoustic brick panel P that should be obtained by laying out the acoustic bricks B with potato joints according to their dimensions, and set the first panel according to the external dimensions.
0 and 11, a formwork step of assembling the horizontal formwork 21 and the vertical formwork 22 on the base 20 with bolts 23 and 24 to assemble the formwork of the desired sound-absorbing brick panel P; 2) Place sound-absorbing brick B in the formwork with its surface side down as shown in Figures 10 and 11.
(3) The vertical and horizontal joints 1 formed between the laid sound-absorbing bricks B are obtained as shown in Figs. 12 and 13. (4) A joint forming material loading step of loading a joint forming material 26 for forming a tight joint in the sound-absorbing brick panel; 11, 12, and 13, the first joint mortar M is filled with the first joint mortar M to about half the depth of the joint part 1.
Next joint mortar filling step, (5) Fill the joint mortar M with the first joint mortar M, from above the joint mortar M, as shown in Fig. 11.
As shown in Figs. 12 and 13, the reinforcing bars S are placed in the reinforcement process, and (6) the resulting sound-absorbing brick panel P is placed in the joints filled with the first joint mortar M as a base material. (7) a hardware arrangement step of arranging a first mounting jig R and a second mounting jig F for mounting on the furring 9 as shown in FIGS. At the joint part where the reinforcing bars S are arranged and the first mounting jig R and the second mounting jig F are arranged,
Furthermore, a second joint mortar filling step of filling the second joint mortar M up to the back side of the allocated sound-absorbing bricks B; (8) a curing step of curing the first and second joint mortar M; , (9) After the joint mortar M has cured, it consists of a demolding step of removing the formwork.

Here, the joints of the sound-absorbing brick B are not limited to the potato joints as in the embodiment, but may be other joints such as torn joints, if necessary.

The base 20, the horizontal frame 21, and the vertical frame 22 are all made of steel, but may be made of wood or resin. Moreover, the base 20 is a sound-absorbing brick panel P
It is of a size that can be carried by hand and is suitable for making only one sheet, but a relatively large fixed type that is suitable for making multiple sheets side by side at the same time may also be used.

As the joint mortar M, resin mortar is used.
Since this is to be filled into the reinforced joint 1, it is desirable to prepare a material that is soft and fluid.

The filling of the joint mortar M is carried out by taking the mortar M into a small scoop, pouring it into the joint part 1 while lightly poking it with a spatula or rod-shaped trowel, and pressing it well.

Although the first mounting jig R and the second mounting jig F are buried in the joint mortar M independently of the reinforcing bars S in the embodiment, they may be welded to the reinforcing bars S and attached integrally therewith. This is superior in terms of strength.

Furthermore, when installing the first mounting jig R, it is inserted into the hardware insertion hole 22a (FIG. 10) of the vertical frame 22 from the outside.

The method for manufacturing a sound-absorbing brick panel according to the second invention is as follows:
Since it is constructed from the above steps, the following effects can be obtained.

In other words, it is possible to arrange the sound-absorbing bricks with high precision, and to increase the accuracy of the combination of the sound-absorbing bricks based on this, that is, the accuracy of the assembly. Therefore, it is possible to eliminate variations in the accuracy of assembling sound-absorbing walls due to skill level, etc., which occurs in conventional on-site construction.
