Description

[Detailed description of the invention] This invention relates to a support device for anchor bolts for foundations, and is used to support foundation members such as foundations, as well as building members called wall panels, in the construction of general houses and other buildings. The present invention relates to a foundation anchor bolt support device for accurately positioning and supporting anchor bolts to be fixed onto a cloth foundation at predetermined locations during foundation construction.

In the past, a few proposals have been made regarding devices for positioning and supporting this type of anchor bolt between concrete forms for foundation construction that are temporarily constructed facing each other.

However, these conventional products are troublesome to install, do not allow accurate positioning, and
The problem was that the support of the anchor bolts was weak and the anchor bolts could be misaligned or tilted when pouring fresh concrete. nevertheless,
It is not impossible to correct such slight deviations and inclinations by changing the position of the anchor bolt mounting holes in the base or by re-bending the anchor bolts themselves.

However, in recent years, a simple construction method has been developed in which rectangular composite boards called wall panels are constructed directly on the cloth foundation, without building a foundation on the cloth foundation. . This construction method involves sequentially supporting and fixing wall panels to each anchor bolt set up at a predetermined interval on a cloth foundation. There was a risk that the wall panels would become uneven.
Additionally, since the wall panels themselves are standardized and manufactured, including the anchor bolt mounting holes, if the height of the anchor bolts above the foundation is inaccurate, the wall panels may not be able to be fixed or may not be able to be fixed properly. There was also the possibility that it would become difficult.

For these reasons, there has been a strong demand for the development of a robust support device that can withstand the accurate positioning of anchor bolts and the pouring of fresh concrete during the construction of concrete foundations.

This invention was devised to provide an anchor bolt support device that can quickly and reliably adapt to the new construction methods mentioned in recent years. A board is formed to be supported and fixed in an erected manner on the upper horizontal parts of both concrete forms for temporary foundation construction, and wedges are formed by fixing both side wall ends of channel steel near the center of one side of this board. A charging window with a long hole in cross section is formed so that the anchor bolt can pass through the anchor bolt loosely. The reason lies in the fact that the elongated holes are formed so as to coincide with the orthogonal lines of the substrate.

An embodiment of this invention will be described below.

In the figure, reference numeral 1 denotes a steel substrate having a substantially H-shape in plan, and both ends of the substrate 1 serve as mounting portions 2 for mounting on the upper horizontal portion of a concrete form P for foundation construction. By holding both the mounting portions 2 in a simple vise J, they are supported and fixed between the two concrete forms P in an erected manner.

Of course, in this invention, the means for fixing the mounting portion 2 is not limited to the simple vise J as shown in the illustrated example, and other fixing means such as screws may be optionally used.

In the vicinity of the center of the support part 3 that connects both the mounting parts 2, a charging window 5 having an elongated cross section is formed by fixing the ends of both side walls of a predetermined channel steel 4. A wedge 7 fitted with a ring 6 to prevent it from falling loosely passes through the charging window 5.

Further, a long hole 8 for allowing the anchor bolt A to pass through the bottom wall of the channel steel 4 and the support portion 3 of the base plate 1 facing the bottom wall is bored.
In this case, since both free elongated holes 8 are parallel and are formed so as to coincide with the orthogonal line of the board 1, the board 1 is supported horizontally and the anchor bolt A is set free. A wedge 7 is inserted into the long hole 8.
If you drive in, anchor bolt A will always be supported vertically.

At this time, by forming the free-through elongated hole 8 into a long hole shape so that two anchor bolts A can pass through it, for example, the anchor bolt A can be supported on either the left or right side of the free-through elongated hole 8. There is an advantage that the positioning of the anchor bolt A can be selected in two ways. In other words, the anchor bolt mounting hole S of the wall panel W as a building member for a general house built directly on the cloth foundation F is set at a position of 45 m/m or 60 m/m from the inner wall of the outer concrete form P. In many cases, the design is limited to two types, such as the following, and if the formation position of the free through hole 8 is also drilled to match this, depending on the type of wall panel W,
The anchor bolt A can be quickly positioned and supported.

In addition, the free through hole 8 between the concrete formwork P
In order to ensure the accuracy of the setting position, a part of the support part 3 is cut and bent to form a locking piece 9, and this locking piece 9 is brought into contact with the inner wall of the concrete formwork P to hold the board 1. It is also good to support and fix it.

On the other hand, as shown in the illustrated example, by forming the board 1 into a substantially H-shape in plan, the anchor bolts A can be set even at the corner portions of the cloth foundation F.
Furthermore, by forming the mounting portion 2 to be as narrow as possible, it is possible to prevent it from interfering with the work of placing fresh concrete.

Next, to explain how to use this, the mounting part 2 is placed on the horizontal part of the upper end of the concrete form P that will be temporarily installed in line with the set position of the anchor bolt A, and the board 1 is erected, and then placed in a simple vise J. Both attachment parts 2 of the lever are firmly clamped and fixed. And wall panel W
When trying to set the anchor bolt A at a position of 45 m/m from the inner wall of the outer concrete formwork P, corresponding to the position of the anchor bolt mounting hole S,
As shown in Figs. 1 and 3, the anchor bolt A is loosely inserted into the left side of the elongated free-through hole 8, and after adjusting it to a predetermined height, the wedge 7 is driven in for positioning and support. .

When setting the anchor bolt A at a position 60 m/m from the inner wall of the concrete formwork P, that is, at the center of both concrete formworks P in the illustrated example, it should be set on the right side of the free through hole 8 as shown in Fig. 4. Just let it go through and drive wedge 7.

After the placed fresh concrete has hardened, it can be easily removed from the anchor bolt A by tapping the head on the opposite side of the wedge 7 that has been placed, so it can be used as often as needed.

According to this invention constructed in this way, the substrate 1 is formed to be supported and fixed in an erected manner on the horizontal portions of the upper ends of both concrete forms P for foundation construction which are temporarily constructed facing each other, and the support portion 3 of the substrate 1 is formed. Near the center, channel steel 4
A charging window 5 having an elongated cross section is formed by fixing both side wall ends of the wedge 7 to allow the wedge 7 to pass freely therethrough.
Since a free-through elongated hole 8 was drilled to allow the anchor bolt A to pass through the anchor bolt A loosely, the anchor bolt A can be easily inserted by simply passing the anchor bolt A loosely through both of the free-through elongated holes 8 and then driving the wedge 7. The anchor bolt A can be accurately positioned, and the anchor bolt A can be firmly supported. Therefore,
Anchor bolt A by pouring fresh concrete
There is no risk of the setting position shifting or tilting, so you can use it with confidence.

In addition, since the two free elongated holes 8 are formed so as to coincide with each other on the orthogonal line of the substrate 1, the anchor bolt A can be vertically supported by simply driving the wedge 7, and the supporting state can be maintained as described above. is extremely strong, so once the anchor bolt A is set, ready-mixed concrete can be placed without any worries.

In this way, the anchor bolt A is erected accurately at a predetermined location, so even when the wall panel W is constructed directly on the cloth foundation F by fixing it to the anchor bolt A, the wall panel W will not tilt. Therefore, accurate construction of the wall panel W based on a predetermined design and rapid construction work can be expected. Naturally, this invention can also be used when constructing a foundation on a cloth foundation F.

In addition, after the fresh concrete cast between the concrete forms P has hardened, it can be easily removed from the anchor bolt A by tapping the head on the opposite side of the wedge 7, which has the advantage of being able to be used over and over again. be.

Furthermore, since the charging window 5 is formed to have a long hole shape in cross section so that the wedge 7 can pass through it, and the play hole 8 is formed in a long hole shape, the free penetration length of the anchor bolt A is reduced. It is now possible to choose between two sides of the hole 8, so that it can be built directly on the cloth foundation F,
The anchor bolt A can be quickly and accurately positioned at a predetermined location in response to two types of wall panels W as building components for general houses, where the anchor bolt mounting hole S is often designed to have only two positions. It can be supported by

As explained above, according to this invention, in the construction of general houses and other buildings, anchor bolts for fixing foundation members such as foundations, as well as building members called wall panels, on the foundation. It has various practical effects such as being able to accurately and quickly position and support a predetermined location during foundation construction.
