JP2000248558A - Continuous footing for forming truss structure by using h steel for upper main reinforcement - Google Patents

Abstract

PROBLEM TO BE SOLVED: To attain high strength by improving bar arrangement of a continuous footing, and to facilitate execution work and joining with an upper building by using H steel in an upper part, and forming a truss structure by integrally forming these by facilitating joining with a lower main reinforcement by a U-shaped reinforcement. SOLUTION: A truss structure is formed by using H steel 1 as an upper chord member, an anchor reinforcement 3 and concrete 7 as a chord member and a lower main reinforcement 4 as a lower chord member. The reinforcement 3 is inserted into the H steel 1 and a reinforcement 3 flange 8 to be fixed by a welding part, the concrete 7 is placed, and the H steel 1, the reinforcement 3 and the main reinforcement 4 are integrally formed. An angle is installed in a lower part of the main reinforcement 4 to be joined with the main reinforcement 4. Thus, a right level and a position can be set by arranging the H steel 1 in a right position, yield strength of the H steel 1 is compounded as a truss structure by the reinforcement 3 and the lower main reinforcement 4 to cope with a load, and a high yield strength and highly accurate foundation can be formed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[Industrial application] High strength using H steel on the top,
High-strength joints with upper buildings, high-precision construction, and a labor-saving foundation

[0002]

2. Description of the Related Art The level of the upper part of the foundation has been raised, anchor bolts have been installed, and the foundation has been joined to the upper building. Main muscle,
The abrasion streaks corresponded to the load as a fabric base.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to improve the arrangement of reinforcing bars in a cloth foundation, to provide a high-strength foundation structure that can be easily constructed and joined to an upper building.

[0004]

[Means to solve the problem] Using H steel on the upper part,
The U-shaped rebar facilitates the connection with the lower main rebar and is integrated therewith, increasing the bending strength of the truss structure and the high strength foundation with the bending strength of H steel. By welding the anchor bolts to the upper H steel at the site, a high-precision position can be joined to a high-strength upper building.

[0005]

[Function] A truss structure using H steel as an upper material, anchor reinforcing steel and concrete as a material, and a lower main bar as a lower material. As shown in the enlarged view of FIG. 3, the H steel and the reinforcing steel are passed through the flange, fixed by welding, and cast concrete, and the H steel, the reinforcing steel, and the main reinforcing steel are integrally formed. Angles at the bottom of the main bars in Figs. 5 and 7
10 ▼ can be attached to the main bar. 7 and 8
The H steel is also used at the lower part of the upper H steel, and it is connected with the anchor rebar to form a truss structure.

[0006]

[Example] H steel was used for the upper part and H steel was used for the lower part, and four steel bars shown in Figs. 5, 6, 7, 8, and 9 were removed from the hoop.
6) forms a column, and forms a steel and truss truss structure with H steel, and can be used as a foundation beam having a high strength especially when the foundation is high. When the foundation is installed on the deformed ground shown in FIGS. 10, 11 and 12, the height of the foundation beam is higher than the height of the foundation beam. ,
The beams (11) and (17) are connected by a beam (18) corresponding to the deformed ground composed of H steels (14) and (15), so that a high-strength base for deformed ground can be obtained.

[0007]

According to the present invention, if H steel is used on the upper part of the cloth foundation, the correct level and position can be set by installing the H steel at the correct position. It can handle loads by compounding as a structure, and has high proof stress,
The foundation of high precision is made.
