Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Use" The present invention relates to a foundation construction block when a precast concrete foundation construction block structure formed in advance in a factory, etc. is used to construct the foundation of a house, etc. Regarding the joint structure of N4 structures.

``Conventional Technology J As is well known, the foundations of houses were generally formed by pouring concrete on-site, but this construction requires a large number of steps, so the construction period and construction costs are It was difficult to reduce the number of

Therefore, in recent years, the use of precast concrete foundation construction block structures that have been preformed in factories etc. for the foundations of houses, etc. has been installed at the construction site and used as the foundation, thereby saving labor at the construction site. and simplification.

This block structure has a cast-in-place foundation divided perpendicularly to the longitudinal direction of the foundation. The reinforcing bars extending longitudinally inside the block structure were connected by welding.

The above-mentioned foundation is constructed in the same way as a foundation using cast-in-place concrete; a hole is formed in the ground, crushed stone is placed at the bottom of the hole, and it is compacted to form the foundation. It was built by pouring concrete onto the ground.

[Problem to be solved by the invention] By the way, by manufacturing the foundation in advance as a foundation construction block structure in a factory etc., it is possible to save labor at the construction site, but welding the reinforcing bars is This is a special technique and requires skilled work.

There was a problem in that this required a welder and the like, which was an obstacle to labor-saving construction of the foundation.

The present invention has been made in view of the above-mentioned circumstances, and is a block structure for foundation construction which aims to save labor and simplify the joining of block structures for foundation construction, thereby reducing the construction cost and construction period of foundation construction. The purpose is to provide a joint structure for this purpose.

"Means for Solving the Problems" The joint structure of the foundation construction block structure according to the present invention is as follows:
A foundation footing that is placed on the foundation and a rising portion that is provided on the foundation footing and on which a superstructure such as a house is placed are integrally formed, and are connected and installed on the foundation. This is a joint structure for joining foundation construction block structures that form the foundations of houses, etc., by connecting the sheath pipe embedded in the joint surface of the block structure and the longitudinal direction of the block structure. It is equipped with reinforcing bars that are buried inside, pass through the inside of the sheath pipe, and protrude from the joint surface of the block structure, and an injection hole that is drilled in the side of the block structure so as to communicate with the inside of the sheath pipe. The joint surfaces of the block structures are brought into contact with each other, and the reinforcing bars protruding from the other sheath pipe are inserted into the inside of one sheath pipe, so that the adjacent reinforcing bars overlap each other, and the liquid is poured from the injection hole. The solidifying agent is injected and solidified.

"Operation" According to the configuration of the present invention, in order to construct a foundation using the foundation construction block structure equipped with the joint structure of the present invention,
First, a root cutting hole is made at the construction site, a ground cutting is provided at the bottom of the root cutting hole, and a foundation is installed on the ground cutting. Then, block structures are placed in series on this base. On this occasion,
Insert the reinforcing bars that pass through the sheath pipe and protrude from the end face of the block structure into the sheath pipe of the adjacent block structure, thereby overlapping the reinforcing bars of the adjacent block structures inside the sheath pipe. . Then, a liquid solidifying agent is injected through an injection hole formed in the side surface of the block structure. As a result, the solidifying agent hardens without the need to join reinforcing bars by welding as in the past.
Overlapping reinforcing bars inside the sheath pipe can be easily and firmly connected.

"Example" An example of the joining structure of the foundation construction block structure of the present invention will be described with reference to FIGS. 1 to 4.

FIG. 1 shows a block structure I used in the present invention.

Inside this block structure 1, there is a foundation footing m I
Reinforcing bars 2.3 are buried in the longitudinal direction of the rising portion 1b and the rising portion 1b. Then, the joint 4 of the block structure l
A cylindrical sheath tube 5 is embedded in the longitudinal direction, and the reinforcing bars 2 and 3 pass through the sheath tube 5 and protrude from the joint 4a.

Also, block structures! An injection hole 6 communicating with the inside of the sheath tube 5 is bored in the side surface of the sheath tube 5 .

A liquid solidifying agent such as Braut's material is injected into the sheath tube through the opening of the injection hole 6.

Note that the reference numeral 7 in the figure is a block connecting bolt 7 having threaded portions formed at both ends. This bolt 7 for connecting blocks 7 is inserted into the bolt hole 8 of the adjacent block structure 1, and both ends are tightened through the opening 9 using nuts I6 to fix the block structures I together. be.

In order to construct a foundation using the block structure ■ having the above configuration, first, a root cut hole is made at the construction site, a ground work is provided at the bottom of this root cut hole, and the foundation II is installed in this ground work. establish. Then, the block structures 1 are placed in series on this base II (see FIG. 2). Then, the reinforcing bars 2 passing through the sheath pipe 5 and protruding from the joint surface 4a of the block structure 1 are inserted into the interior of the north pipe 5 of the adjacent block structure 1, so that the amount of adjacent reinforcing bars ±2 .2 and 3,
3 are overlapped inside the sheath tube 5. In parallel with this, the block connecting bolt 8 is inserted into the bolt hole 8 of the adjacent lock structure I, and both ends of the block connecting bolt 8 are tightened with nuts 10 through the opening 9 to connect the block structures I. (see Figure 3).

Next, a liquid assimilating agent I2 such as Braut's material is injected through an injection hole 6 formed in the side surface of the block structure I. Then, as the solidifying agent 12 solidifies, the overlapping reinforcing bars inside the sheath tube 5 of ±2.2 and 3.3 are firmly connected (see FIG. 4). As a result, a foundation is constructed using a plurality of block structures l.

As can be easily understood from the above description, in this embodiment, the joint surfaces 4a of the block structures 1 are brought into contact with each other, and a part of the sheath pipe 5 protrudes from the other sheath pipe 5 into the inside of one sheath pipe 5. By inserting the reinforcing bars 2 and 3 that overlap the adjacent reinforcing bars by ±2.2 and 3°3, and injecting the solidifying agent 12 from the injection hole 6, there is no need for conventional welding work. By solidifying the solidifying agent 12, the overlapping reinforcing bars of ±2.2 and 3.3 inserted into the north pipe 5 can be reliably and firmly connected.

"Effects of the Invention" As explained above, according to the joint structure of the block structures for foundation construction of the present invention, the joint surfaces of the block structures are brought into contact with each other, and the sheath pipe of the other is placed inside one sheath pipe. By inserting the reinforcing bars protruding from the pipe, overlapping adjacent reinforcing bars, and injecting a solidifying agent through the injection hole, the solidifying agent solidifies and overlaps the reinforcing bars to create a north-south shape without the need for conventional welding work. Since the reinforcing bars inserted inside the pipe can be reliably and firmly connected to each other, the joining of block structures can be simplified and labor-saving, thereby shortening the construction period and cost of foundation construction.
