Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the construction of a concrete foundation provided with anchor bolts, etc., until the cast concrete is sufficiently set and the anchor bolts are stably held. The present invention relates to provision of a temporary retainer for an anchor bolt that is retained in a position and in a desired posture.

[0002]

2. Description of the Related Art In the construction of concrete foundations such as cloth foundations, anchor bolts, which are usually used for mounting foundations, are constructed so that their mounting portions protrude from the top end of the concrete foundations to be constructed. The mounting portion is provided so as to stand upright from the concrete foundation.

Such an anchor bolt is assembled, for example, so as to stand upright at a predetermined position with respect to the top surface of the foundation concrete when constructing a concrete foundation, and vertically so as to have a predetermined protrusion size. It is configured so that the posture can be maintained until the concrete to be cast into the concrete solidifies.

However, in such a method of holding the anchor bolt, the anchor bolt is formed in a predetermined position, and further, the anchor bolt is formed so as to have a required protruding dimension from the top end surface of the foundation concrete to be formed. Alternatively, it is necessary to perform a formwork construction or a bar arrangement construction for fastening to each rebar or the like, which requires a lot of work by a skilled person.

Further, according to such a method, the displacement of the mounting position of the anchor bolt is apt to occur during the placing of concrete, and the anchor bolt is inclined or installed and attached in accordance with the placing of the concrete. This often causes inconveniences such as the movement of the position downwards, so that, for example, an inclined anchor bolt may be reworked to a vertical position or seated against a base that is attached to the anchor bolt. It was necessary to readjust around the foundation, such as by treating the moat.

From this point of view, the concrete is poured into the assembled base formwork, and before the concrete is poured, the anchor bolt is inserted into the cast concrete to fix the anchor. A method of equipping the concrete foundation with bolts is used.

In a method of inserting anchor bolts into the cast concrete foundation and directly equipping the concrete foundations with the anchor bolts, the anchor bolts are scheduled in advance for the formwork or the reinforcing bar. Based on this mounting posture, various operations for accurately mounting and holding this are not necessary, and no countermeasures against impacts on anchor bolts caused by concrete pouring are required, and relatively easily. It has the feature that a concrete foundation with anchor bolts can be constructed.

[0008]

However, in the method of inserting the anchor bolt into the concrete of the cast concrete foundation, the anchor bolt to be inserted into the unconsolidated concrete is
Due to its own weight, it tends to sink, and even if it is an anchor bolt that is set vertically along the water thread and with the required protruding dimension due to the degree of contact with the mixed aggregate etc., after this setting Over time, it was necessary to monitor the degree of sinking, the inclination, etc., and readjust.

Further, in order to avoid the sinking or tilting of the set anchor bolt as much as possible, for example, the anchor bolt is inserted into the cast concrete in a state where the solidification action of the cast concrete is considerably advanced. In such a case, the insertion of the anchor bolt itself may be difficult, and it may be difficult for the concrete to fit into the inserted anchor bolt.

From this point of view, in the conventional method in which the anchor bolt is directly inserted and set in the cast concrete, the concrete suitable for inserting the anchor bolt after placing the concrete in the foundation formwork is used. It was necessary to insert the anchor bolts into the pouring concrete while judging the degree of solidification from the intuition of the operator and watching the time, which caused many inconveniences in the management of the work schedule.

The present invention eliminates the disadvantages of the conventional anchor bolt assembling method, and does not impose a timing restriction on the insertion of the concrete into which it is placed. An object of the present invention is to provide a temporary retainer for an anchor bolt, which can be inserted and set in the anchor bolt, and which can be surely installed on a concrete foundation without the set anchor bolt sinking or tilting.
