Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lightweight cellular concrete panel (hereinafter referred to as an ALC panel) which is attached to a steel frame of a building to constitute a wall, a roof, a ceiling, etc., and is particularly embedded in the panel. The present invention relates to the structure of a reinforcing steel mat and a panel manufacturing technique thereof.

[0002]

2. Description of the Related Art The dimensions of this type of building ALC panel are generally 300-600 mm in width W, depending on the structure of the building.
Thickness H75-150mm, length L600-5000mm
As shown in FIG. 3, a plurality of main bars 2 arranged in the longitudinal direction and a plurality of main bars 2 fixed perpendicularly to the main bars are provided in accordance with the required strength of the panel. An ALC panel 20 is formed by embedding a reinforcing bar mat 20-1 in which two wire-mesh mats composed of the horizontal streaks 3 are combined in parallel on the tension side and the compression side.

[0003] The above-mentioned building ALC panels are manufactured in a required number of pieces at a factory based on specifications determined based on the design of the building, and the factory manufactures panels having predetermined dimensions and structures determined from the beginning. Therefore, if a defective part or defective product that is difficult to repair for any reason during the manufacturing process or handling occurs, it is impossible to cut and remove the defective part. It was necessary to remanufacture the panel products at the factory, which not only required a lot of labor and time, but also had to delay the delivery time of the panel products and the construction period.

On the other hand, an ALC panel for a wall is attached to a frame or a pillar with bolts. In the case of an ALC panel for a wall, if a horizontal streak is arranged within about 100 mm from a panel mounting bolt position. For this reason, a long panel having the same width and the same thickness as the defective panel can be cut and used in many cases. However, in the case of floor, roof, and ceiling panels, both ends in the longitudinal direction are suspended on beams or joists, so unless two or more horizontal streaks are placed within 30 mm from the small edge surface at both ends and within 200 mm on the tension side. No. Therefore, for example, as shown in FIG. 4, the thickness H is 150 mm, the length L is 4100 mm, and the horizontal streaks 3 of the mat 30-1 on the tension side have the lengths l ₁ , l ₂ , l
_{3, l 4,} respectively 18mm, 143mm, 393m
m, 643 mm, the fifth and subsequent wires are arranged at a pitch of 703 mm, and the horizontal streaks 3 of the mat 30-2 on the compression side are arranged at positions opposite to the tension side except for removing the horizontal streak 3 at the extreme end on the tension side. In the case of the floor panel 30, even if the panel is cut at an arbitrary position, it is 30 m from the small edge face 30-3 at both ends.
m, and the condition that two or more horizontal streaks must be arranged within 200 mm on the tensile side cannot be satisfied. For this reason, in the case of floor, roof, and ceiling panels, long panels cannot be cut and used as substitutes, and panels with predetermined intervals must be remanufactured.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and has a desired length in the case of defective products not only for walls but also for floors, roofs and ceiling panels. An object of the present invention is to propose a length-adjusting ALC panel that can be cut into pieces and used as a substitute, and a method of manufacturing the same.

[0006]

The ALC panel for length adjustment according to the present invention comprises a wire mesh mat comprising a main bar in the longitudinal direction and a horizontal bar perpendicular to the main bar. An ALC panel having a structure in which rebar mats combined in parallel are buried, wherein at least the wire mesh mat on the tension side has a length of 30 mm, 70 mm, 110 mm, and 280 mm or less from one edge in the longitudinal direction of the panel. The horizontal streak is arranged at a position, and the other end of the wire mesh mat on both the tension side and the compression side is located within 30 mm from the other edge face, and the second and subsequent horizontal streaks are scheduled to be cut at the mat. 170m at least one pitch ahead
It is characterized by being constituted by rebar mats arranged at a pitch within m.

[0007] Further, as a method of manufacturing the same, a wire mesh mat composed of a main bar in a longitudinal direction and a horizontal bar perpendicular to the main bar is embedded in a reinforcing bar mat in which two mats are combined in parallel on a tension side and a compression side. In manufacturing the ALC panel having the above-mentioned structure, at least the mat on the tension side is placed at a distance of 30 mm, 70 mm, and 110 mm from one of the edge faces in the longitudinal direction of the panel.
mm and 280 mm, and the outermost streak is fixed within 30 mm from the other opposite edge of the mat on both the tension side and the compression side.
The reinforcing bar mat is characterized in that the horizontal streaks subsequent to the first stitch are fixed at a pitch of 170 mm or less to at least one pitch ahead of the planned mat cutting position.

[0008]

FIG. 1 shows a length adjusting A according to the present invention.
This is an example of the structure of the reinforced mat of the LC panel.
(A) is a plan view showing a part of a tension-side reinforcing arrangement,
(B) is a plan view showing the reinforcement side structure on the compression side partially omitted,
FIG. 2 is a partially omitted illustration of an ALC showing another embodiment of the present invention.
It is a vertical front view of a panel, 1 and 11 are ALC panels,
1-1 and 11-1 are wire mesh mats on the tension side, 1-2 and 1
1-2 is a wire mesh mat on the compression side, 1-3 and 11-3 are fore-edges, 3-1 and 3-2, 3-3 and 3-4 are horizontal streaks.

The dimensions of the ALC panel 1 shown in FIG.
It is 600 mm in thickness, 150 mm in thickness, and 4100 mm in length. The inside of the panel is embedded with a reinforcing bar mat in which a wire mesh mat 1-1 on the tension side and a wire mesh mat 1-2 on the compression side are combined in parallel. The wire mesh mat 1-1 on the tension side in this reinforcing bar mat has six main reinforcing bars 2 having a diameter of 5 mm.
And a large number of horizontal streaks 3 having a diameter of 5 mm, which are arranged orthogonally to the main streaks, and the left end face 1-3 of each horizontal streak is fixed.
The distance l _1-1 of the endmost horizontal streak 3-1 is 2
0 mm, the distance l _1-2 of the second horizontal streak 3-2 is 60 m
m, the distance l _1-3 of the third horizontal streak 3-3 is 100 mm,
The distance l _1-4 of the fourth horizontal streak 3-4 is 220 mm. Further, the wire netting mat 1-2 on the compression side is
Is the same as the pull-side wire mesh mat, and the horizontal stripes 3 are the same as the pull-side wire mesh mat except that the second horizontal stripe 3-2 is omitted from the left edge 1-3 of the pull-side wire mesh mat. Is arranged at a position opposite to the wire mesh mat 1-1.

On the other hand, the distance from the right edge face 1-3 of the panel is the same pattern for both the wire mesh mat 1-1 on the tension side and the wire mesh mat 1-2 on the compression side. The distance l _1-1 of 1 is 20 mm, and the second horizontal streak 3-2
Distance _{l 1-2} is 140 mm, 3 knots lateral stripes 3-3 and subsequent of the distance _{l 1-3} is the distance _{l 1-4} of 260 mm, 4 knots lateral stripes 3-4 380 mm, 170 by 120mm pitch
Fifteen horizontal streaks 3 are arranged to 0 mm, and a horizontal streak of 220 mm from the left end forefront 1-3 and one to one from the right end forefront 1-3
The spacing between the 700 mm horizontal streaks is arranged at a pitch of 600 mm to 640 mm.

Therefore, in the case of the ALC panel 1 having the above arrangement, if a panel having a length L of 4090 mm is required, it is cut at a position 10 mm from the left to obtain a horizontal line 3.
Is located 10 mm, 50 mm, and 90 mm from the left edge and 20 mm and 140 mm from the right edge. If a panel with a length L of 4080 mm is required, cut at each 10 mm position on the left and right, and the position of the horizontal streak from the left edge of the front edge is 10 mm, 50 mm,
It becomes 90mm, and the distance of the horizontal streak from the right edge front is 10m
m, 130 mm. Thus, the panel length L
Can be handled at a pitch of 10 mm from 4100 mm to 2500 mm.

In this example, the reason why the horizontal streak position at the outermost end is 20 mm from the fore edge and the pitch is 120 mm after the second stitch is due to consideration of the position accuracy of the reinforcing bar in the manufacturing process, manufacturing equipment, and the like. The reason why the horizontal streak is set to 1700 mm from the right side is that all the horizontal streaks other than both ends of the panel are 12 mm.
By arranging at a 0 mm pitch, it is possible to correspond to all lengths of the same width and the same thickness panel, but since the number of horizontal stripes increases, for a panel of 2500 mm or less,
This is because it is more economical to prepare a shorter adjustment panel.

Next, an ALC panel 11 shown in FIG. 2 is an example of the smallest panel having a thickness of H70 mm, a width of W283 mm, and a length of L1890 mm. 3 main bars 2 of 5mm
And a large number of horizontal streaks 3 having a diameter of 5 mm fixed perpendicular to the main streaks 2, and the left end face 11-3 of each horizontal streak.
The distance l _1-1 of the endmost horizontal streak 3-1 is 2
0 mm, the distance l _1-2 of the second horizontal streak 3-2 is 60 m
m, the distance l _1-3 of the third horizontal streak 3-3 is 100 mm,
The distance l _1-4 of the fourth horizontal streak 3-4 is 220 mm.

The wire mesh mat 11 on the compression side of the panel
2, the main reinforcement 2 is the same as the tension side wire mesh mat 2-1, and the horizontal stripe 3 is the tension side wire mesh mat 11-
Except for omitting the horizontal streak corresponding to the second second horizontal streak 3-2, horizontal streaks are arranged at opposing positions.

On the other hand, the distance from the right end face 11-3 of each horizontal streak is the same as that of the wire mesh mat 11-1 on the tension side and the wire mesh mat 11-2 on the compression side. horizontal stripes 3-1 distance _{l 1-1} is 20 mm, the distance _{l 1-2} two first lateral stripes 3-2 140 mm, 3 knots lateral stripes 3-
After 3 the distance l _1-3 is 260 mm and the fourth horizontal streak 3
4 and 380mm distance _{l 1-4} in at 120mm pitch until 1340mm is 12 lateral stripes 3 are disposed, and the left end small surface 11-3 from 220mm lateral stripes and the right end small surface 11
The interval between the horizontal streaks from -3 to 1340 mm is a 330 mm pitch.

Accordingly, in the case of the ALC panel 2 having the above-described arrangement, if a panel having a length L of 1880 mm is required, the panel is cut at a position 10 mm from the left.
Is located 10 mm, 50 mm, and 90 mm from the left edge and 20 mm and 140 mm from the right edge. If a panel with a length L of 610 mm is required, cut it at the positions of 80 mm and 1200 mm on the left and right sides, and the position of the horizontal streak from the left edge forefront is 10 m as above.
m, 50 mm, and 90 mm, and the distance of the horizontal streak from the right edge face is 20 mm and 150 mm. Thus, the panel length L is 1890 mm to 610 mm,
It can respond at a 0 mm pitch.

The thickness and number (total cross-sectional area) of the main bars of each panel may be appropriately selected as needed.
If the thickness is about 5 to 6 mm, it is easy to cut, and if the total cross-sectional area is 238 cm2 or more per 100 mm of panel width W, a sufficient design load can be obtained by ordinary use. Further, when these panels are cut to a desired length, the cut surface of the main streak is exposed on the short side small edge surface. Therefore, the cut surface of the main streak is coated with a rust inhibitor before use.

There are several types of commonly used panel dimensions having a thickness H of 75 to 175 mm, each having a width W of about 280 to 610 mm, and a length L of 610 to 6000 mm in 10 mm increments. Therefore, these combinations reach a huge number, but since the types of panels actually used are limited, typical thickness, width,
By preparing a plurality of types of adjustment panels that can correspond to the length, it is possible to correspond to most panels.

[0019]

As described above, the length-adjusting ALC panel according to the present invention is provided at least on the pulling-side wire mesh mat from one of the edge faces in the longitudinal direction of the panel.
A horizontal streak is arranged at a position within 0 mm, 70 mm, 110 mm, and 280 mm, and 30 mm and 200 m from the other opposite edge of the wire mesh mat on both the tension side and the compression side.
m, 370 mm and the second and subsequent ones, by arranging the horizontal streaks at a pitch of 170 mm or less up to one pitch ahead of the planned cutting position, do not cut from one edge of the panel, or cut 10 to 80 mm, and cut the rest By cutting from the other fore edge side, a panel of a desired length can be obtained in 100 mm increments, and the position of the horizontal streak of the cut panel is the same as that described above (within 30 mm from both edge fore edge,
Since two or more horizontal streaks are arranged within 200 mm on the pulling side) and the horizontal streaks are always arranged at predetermined positions, it can be used not only for walls but also for floor and roof panels. Therefore, if several types of panels having the reinforcing arrangement according to the present invention are manufactured in advance by changing the thickness and width, if a defective product occurs, the panel can be cut to a desired length and substituted. In addition, there is no need to remanufacture a panel having the same specification as a defective product, and a great effect that a delay in delivery of a product group having various specifications and a delay in construction work can be eliminated is achieved.
