Abstract

(57) [Summary] [Purpose] The objective is to reduce the man-hours for concrete foundation work for laying the foundation of wooden structures and to simplify the work. [Structure] Base concrete and rising concrete are made into one body, and blocks divided in the longitudinal direction are manufactured in advance.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a concrete foundation for laying a foundation in a wooden building.

[0002]

[Prior art]

 Conventionally, the base concrete and the foundation of the start-up concrete until the foundation of the wooden building were laid on-site in the longitudinal direction of the site, as shown in the cross section of Fig. 6. The work process after casting is: formwork mounting, rebar assembly, base concrete placement, formwork removal, marking out, formwork installation, rising concrete placement, formwork removal, anchor set, foundation top end leveling However, the work is not only controlled by the weather, but also requires a lot of man-hours.

[0003]

[Problems to be solved by the device]

 According to the present invention, the base concrete and the rising concrete, which are integrally formed in the longitudinal direction described in the above-mentioned conventional technique, are integrated in the longitudinal direction and divided into blocks in the transverse longitudinal direction to form a reinforcing bar on site. The purpose was to simplify the man-hours for on-site work by allowing the factory to perform work such as assembling, mounting and dismounting of formwork, and pouring concrete.

[0004]

[Means for Solving the Problems]

 The base concrete having the predetermined vertical and horizontal reinforcing bars and the rising concrete are integrally formed into a T shape to form a block having a predetermined length, for example, 1820 mm / 917 mm / 450 mm. As a method of connecting each block in the longitudinal direction on site, a round steel rod is welded to a reinforcing bar on one end face of the block so as to be perpendicular and tangential to the outside. On one end surface on the opposite side of the block, a C-shaped steel tube having a cross-section with an inner diameter slightly larger than the outer diameter of the round steel rod is arranged on the reinforcing bar so that the C-shaped open portion is flush with the one end surface. Weld and embed in concrete. When the block is manufactured at the factory, two ventilation holes are penetrated above the rising concrete, and a lattice steel rod of an appropriate size is arranged in the central portion of the length of the ventilation hole. .

[0005]

[Action]

 After placing and discarding waste concrete (Fig. 6), the block is laid. The block to be connected next is connected to the C-shaped steel pipe at one end of the block using the ventilation hole. Then, the round steel rod at one end of the block is inserted into the C-shaped tube to be attached, and the following blocks are sequentially attached. The insertion interval between the round steel rod and the C-shaped steel pipe is small, but cement paste may be injected into the interval if necessary.

【Example】

 FIG. 1 shows a first embodiment of the present invention, which is a front view, and there is no particular distinction between left and right. A 10 mm round steel rod (2) is welded to a built-in reinforcing bar (4) in the longitudinal direction and tangentially to the end face of the block (1). The length of the round steel bar is such that the upper end is aligned with the upper surface of the block (1) and the lower end is up to the inverted T-shaped horizontal upper surface of the block (1).

On the right side of the block (1), a C-shaped steel pipe (3) is positioned such that the open portion is in the vertical direction and is flush with the end face of the block, and like the round steel rod (2). It welds to the built-in rebar. The length of the C-shaped steel pipe is symmetric to the round steel rod (2). Thus, concrete is poured and molded as a block (1). Regarding the lattice steel rod (6), when the ventilation hole (5) is through-molded in the thick direction of the block, it is positioned at the central portion in the thick direction.

FIG. 2 is a plan view of FIG. 1. As described above, the round steel bar (2) welded to the reinforcing bar (4) is tangential to the block end face, and one of the block end faces has The open portion of the C-shaped steel pipe (3) is flush with the end face.

FIG. 3 is a perspective view showing a case where the above blocks are placed on waste concrete (FIG. 6) and connected.

FIG. 4 shows a second embodiment as a method of connecting the blocks in which vertical recesses (9) and projections (10) are integrally formed on the left end face and the right end face of the blocks. The depth of the concave portion (9) is slightly deeper than the protrusion size of the convex portion (10). If necessary, cement paste may be injected into the gap having the difference in depth.

FIG. 5 is a third embodiment showing a mechanical connection method of left-right perfect symmetry. FIG. 5 (b) shows an embedding screw (11) having a notch on its outer surface in advance during block molding. The blocks are embedded in the recesses (14) formed on the left and right shoulders of the block, and after the blocks are laid, rectangular washers (12) are fastened with the laying bolts (13).

Although the embodiments according to the present invention have been specifically described above, the present invention is not limited to the above-mentioned embodiments and various modifications can be made without departing from the scope of the invention.

[0013]

[Effect of device]

 Regarding the construction of base concrete and rising concrete, which are the foundation foundation of wooden buildings, which was performed exclusively on site work, the present invention was described as a connection or split type that can be manufactured in the factory. The work, that is, the work from the mounting of the formwork to the mortar that evens the foundation roof is labor-saving, and the influence of the weather is reduced, which contributes to the improvement of the productivity of wooden structures.
