JPH0932359A - Earthquake resistant precast strip footing for concrete block fence - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent the collapse of a concrete block fence by an earthquake by providing a plurality of pile driving through-holes in strip footing blocks consisting of reinforced concrete, and inserting pipes in the holes to fix them with fillers. SOLUTION: Precast strip footing main bodies 6 are formed of reinforced concrete when a concrete block fence is constructed and, at the same time, a plurality of pile inserting through-holes 2 are provide to fix them with fillers 3 after piles are inserted. The strip footing main bodies 6 are connected to each other with reinforcement 4. Then, concrete blocks are piled up on the strip footing bodies 6 to construct the concrete block fence. The fence is firmly fixed to the ground. By the constitution, the block fence excellent in earthquake resistance can be obtained.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seismic-resistant precast cloth foundation which is preformed by using reinforced concrete and is provided with a hole for driving a concrete block wall to resist earthquake fall.

[0002]

2. Description of the Related Art In the conventional construction of concrete block walls, there were many quality problems in the most important cloth foundations for preventing the walls from falling. As an example, there were many situations in which thin concrete was simply poured in without performing a fall calculation, the strength of the concrete was not controlled, and there were no reinforcing bars. In addition, due to the small land area in the city, there were situations in which the width of the cloth foundation could not be large enough to withstand a fall.

[0003]

SUMMARY OF THE INVENTION The present inventor has conducted research in order to improve the drawbacks of such cut-out work in construction and lack of control in quality control, and to protect the human life due to the collapse of the fence during an earthquake.

[0004]

As a result, the cloth foundation portion is preformed with reinforced concrete or concrete at a certain size in a place such as a factory under sufficient quality control. In addition, piles for resisting falls will be firmly fixed to the ground. The invention could be completed by installing the through holes for the piles on the cloth foundation.

[0005]

[Function] The precast cloth foundation made according to the present invention has a strong structure because quality control is performed in advance in factories and the like, and it is fixed to the ground by driving the piles through the holes installed in the cloth foundation to make it more earthquake resistant. A fence with a wall is built.

[0006]

EXAMPLES Examples of the present invention will be described below. (A) A hollow portion (1) is formed in the fabric base body (6) to reduce the weight. (B) A hole (2) for pile driving is provided in the cloth foundation body (6), and after the pile is driven, a filling material (3) such as mortar or an adhesive is filled and fixed in a gap between the pile and the hole. (C) The block of the cloth base body (6) and the connecting portion of the block have a structure in which the reinforcing bar (4) is inserted into the hole (5) and joined.

[0007]

[Effect] According to the present invention, the cloth foundation can be surely constructed, and the effect of the pile and the hole for the pile makes the fence, the cloth foundation, and the ground more solidly integrated than before, and prevents the fence from falling during an earthquake to protect lives. You can expect an effect.
