Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a method for connecting buildings and foundation piles in cold regions.

[Conventional technology]

In regions such as Siberia, where the annual average temperature is below -10°C, floors of buildings such as factories and houses should be brought into direct contact with the surface soil, as in warmer regions, or steel frames may be used even if the floors are not in direct contact with the ground. When pillars, etc. are brought into contact with the ground surface, the heat from the building is transmitted to the permafrost layer underground through the frozen active layer on the ground surface, disrupting the thermal balance of the frozen soil and causing changes in the bearing capacity of the supporting ground, causing damage to the upper structure. may have an adverse effect on For this reason, even in buildings, it is necessary to avoid direct contact of building members with the ground surface.

For this reason, in buildings for cold regions using the newly developed prefabricated construction method, concrete foundation piles are protruded above the ground, and the building is placed on top of these piles, creating a considerable height between the building floor and the ground. A space was created to allow air to flow in and prevent the heat from the building from being transmitted to the ground.

[Problem that the invention attempts to solve]

However, since there is no precedent and no experience with this method in Japan, the building is placed on foundation piles that protrude above the ground, preventing the transfer of heat from the building, and ensuring a quick and reliable method. It was difficult to find foundation piles that could be connected to buildings.

The purpose of the present invention is to provide a foundation pile that can be quickly and reliably connected to a building in a cold region while preventing heat transfer from the building, while confirming its effectiveness through experiments and the like.

[Means for solving problems]

In order to achieve the above objective, it is first necessary to place the floor beams of the building on concrete piles that protrude above the ground. The tops of the piles must be on the same plane. For this purpose, a cylinder made of a steel plate is inserted into the head of the concrete pile, which is approximately on the same plane,
Grout mortar was used to make the top of each cylinder flush. Next, by bolting the beam of the floor member to the top of the cylindrical portion of the pile via a hard insulating material, the floor of the building is fixed on the foundation pile protruding above the ground.

[Operation] A cylinder made of steel plate is inserted into the head of a concrete pile, and the tops of each cylinder are adjusted using grout mortar so that they are on the same plane, so it is easy to make the tops of the piles on the same plane. be.

Furthermore, since the beam of the floor member is fixed to the top of the pile with bolts through a hard heat insulating material, heat from the floor is prevented from being transferred to the foundation pile.

[Example of idea]

1 and 2 are a perspective view and a partially enlarged view showing an embodiment of the present invention. In the figure, floor member A
1 and the same member B2 are placed on the concrete foundation pile 3 and combined, a cylinder 4 made of a steel pipe is inserted into the head of the concrete pile 3 which is made approximately on the same plane,
Using grout mortar 5, adjust the top of each cylinder 4 so that it becomes the same plane.

After grout mortar 5 has sufficiently dried and solidified,
If the beam parts 6 of the floor members 1 and 2 are fastened to the foundation pile via a hard heat insulating material (for example, neoprene rubber) 7 with bolts 8 embedded in the cylinder 4 and the grout mortar part, the floor members 1 and 2 2 is foundation pile 3
tightly bound to the top.

[Effects of the invention] When constructing a building on the ground in a cold region with frozen land, concrete foundation piles are made to protrude above the ground, steel plate cylinders are inserted onto the piles, and each structure is constructed using grout mortar. The tops of the cylinders were made on the same plane, and when the floor members of the building were fixed to the foundation piles, they were fixed through a hard insulating material. (1) There was no space between the bottom of the building and the ground. exists,
Because air flows in, the heat from the building does not affect the ground surface (2) It is easy to adjust the level of the foundation piles (3) The heat from the building does not transfer to the foundation piles (4) The construction period is short We were able to obtain excellent effects such as

[Brief explanation of drawings]

FIG. 1 is a perspective view of a building constructed using the prefabricated construction method, and FIG. 2 is a sectional view showing the relationship between foundation piles and beams of floor members. In the figure, 1 and 2 are floor members, 3 is concrete foundation pile, 4 is a cylinder made of steel plate, 5 is grout mortar, 6
is a beam of a floor member, 7 is a hard insulation material, and 8 is a bolt.

Claims (1)

[Scope of utility model registration request] When building a building for cold regions using the prefabricated construction method, when placing the beam of the building on a foundation pile that protrudes above the ground, a cylinder made of steel plate is inserted into the head of the concrete pile, and the inside of the cylinder and the pile are separated. By the prefabricated construction method, the beam of the building is fixed with bolts to the top of the cylindrical pile, the level of which is adjusted using grout mortar filled between the pile and the head of the pile, via a heat insulating material. Foundation piles for buildings in cold regions.
