The present invention relates to a method for constructing a dirt between the sides . 2. Description of the Related Art Conventionally, in a unit-type building constructed by combining a plurality of building units, the following method is used when a floor is formed on the floor side of at least a part of the building units in the building. I have. First, after installing the building unit that constitutes the dirt on the foundation, paste a foamed plastic-based heat insulating material with a predetermined thickness along the inner surface of the foundation from the inner side of the floor beam of the building unit, and from inside the ground Fill multiple layers and squeeze each well.
Next, carry in the crushed stone, leveling work to a uniform thickness, then lay a moisture-proof film on the whole surface, then cast concrete between the soil, and finally cast a finishing mortar. To form a soil. [0003] In the conventional method of constructing a sill, a building unit is installed on a foundation, crushed stones are carried in to the floor side of each building unit, a leveling operation is performed, and then a work is performed. In order to carry in crushed stone, the crushed stone must be carried into each building unit while straddling the floor beam of the building unit . did
Therefore, in such a conventional method, the work of carrying the crushed stone is difficult and troublesome. [0004] It is an object of the present invention to solve such a conventional problem and to provide a unit capable of forming a dirt on the floor side of at least a part of building units in a unit building by a simple working method. It is an object of the present invention to provide a method for constructing a soil in a type building. [0005] The method for constructing a dirt floor in a unit-type building according to the present invention is intended to solve the above-mentioned problems.
The following configuration is provided. In other words, in a unit-type building constructed by a combination of a plurality of building units , at least a construction method of forming a soil on the floor side of some building units, and after forming a foundation on the ground, In the foundation, crushed stone is brought in advance to a place where the floor beam of the building unit installed on the foundation is not located, the crushed stone is leveled after the building unit is installed on the foundation, and then the concrete is crushed from the crushed stone. by Da設the,
The floor beams of the building unit is characterized by forming a <br/> dirt floor in a state buried in the concrete. In the construction of the soil, first, a foundation is formed on the ground. At this time, the soil generated by root cutting is piled up in the foundation before the foundation is formed. If the height of the rising portion of the foundation is formed lower than the height of the normal foundation, the last soil level can be lowered. [0007] Then, crushed stone is transported in advance in a place where the floor beam of the building unit installed on the foundation is not located. In this case, in the case of the method of carrying crushed stone after the building unit is installed on the foundation, there is an advantage that the work can be carried out more easily because the crushed stone must be carried over the floor beam of the building unit. Then, after the building unit is installed on the foundation, the crushed stone is leveled, and then concrete is poured from the crushed stone, so that the floor beam of the building unit is buried in the concrete . Form a dirt floor.
Therefore, the floor beams of the building unit do not need to be exposed, and the floor beams do not need to be straddled when entering or exiting the soil. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a method for constructing a dirt floor in a unit building according to the present invention will be described in detail with reference to the drawings. First,
As shown in FIGS. 1A and 1B, the ground 11 is rooted into a rectangular shape in a plane to form a groove 12 for foundation molding. At this time, the root width is made larger and the root is deeper than in the case where the foundation of an ordinary building is formed. Accordingly, a large amount of the root cuttings 13 are generated, but are piled on the ground 11 in the building surrounded by the grooves 12. Crushed stones 14 are spread on the bottom of the groove 12 for foundation molding, and discarded concrete is hit as necessary. Next, as shown in FIGS. 2A and 2B, the foundation 2 is placed on the crushed stone 14 spread on the bottom of the groove 12 for foundation molding.
Form one. For this, first, the footing portion 22 is formed, and then a rising portion 23 is formed by assembling a mold thereon. At this time, the height of the rising portion 23 is formed lower than the height of a normal foundation. In this way, the floor level between soils formed last can be lowered. Next, as shown in FIGS. 3A and 3B, the root cuttings 13 are buried in the gaps between the foundation 21 and the foundation forming grooves 12. In addition, on the ground 11 in the foundation 21,
The embankment 31 is formed using 3. At this time, the root cut 1
If the soil is not suitable for use under soil concrete, use good soil separately. Even if the soil is good, be sure to perform compaction and watertightness. This can prevent uneven settlement of the concrete between the soil and occurrence of cracks. Further, in the embankment 31, a place where a floor beam of a building unit installed on the foundation 21 is located is confirmed in advance, and the place is dug down to a predetermined depth to form a groove 32. In addition, the crushed stones 33 are previously carried in each building unit to a place other than the groove 32, that is, a place where the floor beams of the building units are not located. This way,
When crushed stones are carried in after the building unit is installed on the foundation, the crushed stones must be carried over the floor beams of the building unit, which is advantageous in that the work can be performed more easily. Next, as shown in FIGS. 4A and 4B, a plurality of building units 41 are installed at predetermined positions on the foundation 21. For this purpose, a crane is used to sequentially lift the building units 41 transported from the factory by truck or the like,
After being carried to a predetermined position on the foundation 21, it is installed on the foundation 21. Each building unit 41 has a rectangular parallelepiped frame formed by a plurality of columns 42 arranged at four corners, a ceiling beam (not shown) connecting the upper ends of the columns 42, and a floor beam 44 connecting the lower ends. In this structure, an outer wall, an inner wall, and the like are appropriately attached to the skeleton. After each building unit 41 is installed on the foundation 21, the beam cover 45 is put over the floor beam 44 adjacent to the building unit 41. [0014] Finally, as shown in FIG. 5 (A) (B), after which leveling the crushed stone 33 is carried into each building unit 41 to a uniform thickness, by Da設the dirt floor concrete 51 thereon the floor beams 44 of the building unit 41 to form a dirt floor in embedded tongue state in the concrete 51. Therefore, the floor beams 44 of the building unit 41 do not need to be exposed, and the floor beams do not need to be straddled when entering and exiting the soil. As shown in FIG. 6, each building unit 4
Regarding 1, a flexible styrofoam plate 46 is attached to the upper part of the adjacent floor beam 44 at the factory, and the periphery thereof is covered with a waterproof sheet 47. Thus, the structure is such that the force from the soil is not applied to the floor beam 44. Also,
After leveling the crushed stones 33, before pouring the slab concrete 51 from above, crushed sand is preliminarily filled with crushed sand, and a moisture-proof sheet 52 is laid on the entire surface, and a reinforcing reinforcing bar 53 is arranged inside. By doing so, the strength can be secured. Therefore, according to the construction method of this embodiment, the floor beams 44 of the building unit 41 are buried in the soil.
Therefore, the floor beams of the building unit do not have to be exposed, and the floor beams do not have to be straddled when entering or exiting the soil. Of course, there is no need to remove floor beams at the construction site, and there is no inconvenience when transporting from the factory to the construction site without attaching floor beams in advance. Further, on the embankment 31 in the foundation 21, the location where the floor beam of the building unit is located is confirmed in advance, and the crushed stone 33 is placed in advance in a location where the floor beam 44 of the building unit 41 is not located. The crushed stones 33 can be easily loaded. By the way, if the crushed stone is to be carried in after the building unit is installed on the foundation, the crushed stone must be carried in across the floor beams of the building unit, which is advantageous in that the work can be performed more easily. As described above, according to the method for constructing the dirt in the unit-type building according to the present invention , the dirt is easily formed on the floor side of some building units in the building by a simple working method. be able to.
