Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention supports, for example, the floor or wall of a house by screwing a support plate with a horizontal top surface at the same height onto the threaded part of an anchor bolt installed in a cloth foundation. The present invention relates to a structure of a foundation for a house that can be easily constructed and formed with high accuracy.

0002

BACKGROUND OF THE INVENTION For example, mortar is often applied to the upper end of a cloth foundation, which is the foundation of a house, in order to make the height level uniform. Conventionally, such mortar has been attached to the entire circumference of the upper surface of the cloth foundation.

However, in the conventional method of applying mortar all around the top of the cloth foundation, the total amount of mortar increases, leading to an increase in material costs, and mortar application is required to cover the entire circumference of the cloth foundation. It is a difficult work to make the height level uniform, and this work requires a lot of effort and is inferior in workability.

[0004] Also, since the mortar top is coated over the entire circumference of the cloth foundation, the height level may not be uniform in some cases, which has a negative impact on the installation accuracy of floors, walls, etc. that are constructed above it. affect

[0005] The present invention provides a structure in which a support plate having a horizontal upper surface is screwed to the threaded portion of an anchor bolt installed in a cloth foundation protruding from the top surface of the cloth foundation, with the heights being the same, and the support plate and the top surface of the cloth foundation are screwed together. The purpose of this project is to provide a structure for the foundation of a house that can form the foundation of a house with high horizontal accuracy, based on filling mortar between the two.

[0006]

[Means for Solving the Problems] In order to achieve the above object, the structure of the house foundation of the present invention includes threaded parts that are installed at intervals in the cloth foundation of the house and protrude from the upper surface of the cloth foundation. A support plate positioned above the top surface of the cloth foundation and having a horizontal top surface is screwed onto the threaded portion of each anchor bolt having the same height, and mortar is filled between the support plate and the top surface of the cloth foundation. ing.

[0007]

[Operation] A support plate, which is positioned above the upper surface of the cloth foundation and has a horizontal upper surface, is screwed onto the threaded part of the anchor bolt installed in the cloth foundation so that the height is the same. Therefore, by rotating the support plate, the height level of the support plate can be made uniform easily and with high accuracy, and the accuracy of building the house can be improved.

Furthermore, mortar is filled between the support plate and the upper surface of the cloth foundation. Therefore, mortar construction can save materials by applying mortar only to the anchor bolt portion, and it is also possible to eliminate the application of mortar all around the cloth foundation, improving workability.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In the figure, the structure of the foundation of a house according to the present invention is such that each anchor bolt A has a threaded portion A1 that is installed at intervals on the cloth foundation F of the house and protrudes from the upper surface of the cloth foundation F. A support plate 4 with a horizontal upper surface is screwed to the same height, and mortar M is filled between the support plate 4 and the cloth foundation F.

As shown in FIG. 6, the cloth foundation F is installed along the outer periphery of the house, and the cloth foundation F1 that supports the walls inside the house has a lattice between the cloth foundations F and F on the outer periphery. It is arranged in a shape. Further, as shown in FIGS. 3 and 5, anchor bolts A are installed on the cloth foundations F and F1 at appropriate intervals.
A threaded portion A1 protrudes from the upper surface of 1 to which a support member 2 for supporting a wall panel PW and a floor panel PF, and a column 3 are attached.

As shown by broken lines in FIG.
, are positioned above the upper surface of F1 and screwed together at the same height, and mortar M is filled between the support plate 4 and the cloth foundation F and the upper surface of F1.

As shown in FIG. 8, the mortar M is applied to cover the lower part of the threaded portion A1 of the support plate 4 prior to screwing into the threaded portion A1.
1, the support plate 4 is screwed onto it.

As shown in detail in FIG. 7, the support plate 4 is made of a square plate in this embodiment, and has a screw hole 4a formed in the center thereof to be screwed into the screw portion A1. As shown in FIG. 9, the support plate 4 has its screw hole 4a screwed into the screw portion A1, and the mortar M attached in advance.
It is installed horizontally above the top surface of the cloth foundations F and F1 while pressing the top surface. Thereafter, as shown in FIG. 10, the upper surface of the horizontal support plate 4 and the upper surface of the mortar M are aligned with a trowel, and the side surface of the mortar M is finished into a planar shape.

[0014] The spacing between the threads of the threaded portion A1 is usually
It is in the range of 2 mm to 3 mm, and the support plate 4 is 9 mm.
By rotating every 0°, the height level can be set by 0.5
It can be adjusted from mm to 0.75 mm as the lower limit,
The height position of the upper surface of the support plate 4 screwed onto each anchor bolt A can be easily and accurately made uniform. In addition, it is only necessary to fill the mortar M at the anchor bolt A position, which reduces material costs and improves construction efficiency compared to the case where mortar is applied over the entire upper surface of the cloth foundations F and F1. It can be planned.
