摘要： PURPOSE:To shorten a term of works by joining a column member and a beam member in a way that the flange part of a embedding metal located to the joint of the column member is connected to a bracket, protruded from the end part of the beam member, by using a joining metal. CONSTITUTION:After a column member 1 erected in a position is coupled to main reinforcing bars 1a and 1a of the column member 1 on the lower floor side, an embedding metal 3 with a gusset plate 8 is installed on the column member 1 and secured to the column member 1. A beam member 2 is then spanned between the column members 1 and 1, a flange 4b of a bracket 4 of the member 2 is joined with a bracket 3b of the metal 3 through a joining metal 5 by means of bolts 6. A web 4a of the bracket 4 is joined with a plate 8 of the metal 3 by means of a bolt 6 to support the load of the beam member 2 directly to the column member 1. Forms are installed around the end part of the beam member 2 and the joint to place concrete. This method causes a work to save a labor.

摘要： PURPOSE:To increase the degree of freedom for the construction plan of a building and reduce the construction cost by forming a plurality of subsoil improvement bodies of large bore in a weak subsoil immediately under a building foundation, and jointing the foundation under tension to the improvement bodies with ground anchors. CONSTITUTION:A pit is drilled under a building foundation and a pipe 2 is inserted therein. In addition, an ultra-high jet flow containing a curing agent is blown underground via the pipe 2 and a columnar soil improvement body 3 of large bore is formed with the agent and sediment, while the surrounding ground is being drilled. Before the improvement body 3 is cured, a ground anchor tension member 6 and the underground fixing body 4 of a ground anchor are buried in the body 3. After the improvement body 3 is cured and the strength thereof is realized, a building foundation 7 as constructed and the improvement body 3 are jointed to each other under tension with the tension member 6 tightened, thereby fixing the foundation 7 to the improvement body 3. According to this constitution, the degree of freedom for the construction plan of a building can be increased, compared with the conventional method, and the construction cost can also be reduced, compared with the conventional foundation piling method.

摘要： PURPOSE:To reduce the rolling of a water surface construction so as to improve living environment by binding the foundation of the water surface construction and soil improving bodies constructed in the mooring location by numerous ground anchors, and forming an air volume adjusting closed chamber inside the water surface construction. CONSTITUTION:In order to moor a water surface construction 7, soil improving bodies 3 of large bore are numerously built underground directly under a mooring location or in the vicinity thereof. The underground anchor bodies 4 of ground anchors embedded in the respective soil improving bodies 3, and the foundation 8 of the water surface construction 7 are mutually bound by numerous tension members 6 including the tension members 6 of the ground anchors disposed obliquely. A closed chamber 9 is then formed in the construction 7, and a pipe 10 for making water flow in/out from the lower side of the foundation 8 is disposed at the closed chamber 9 so as to change air volume in the closed chamber 9 interlockingly with the vertical movement of the outside water surface. The rolling of the construction 7 caused by a water current, waves and wind is thereby reduced to improve living environment.

摘要： PURPOSE:To enhance the efficiency of construction work and to secure high accuracy in building a structural stud into a foundation consolidation portion by inserting a pipe into a vertical hole drilled in the ground, and injecting a jet to the foundation consolidation portion of the and building the structural stud into the foundation consolidation portion. CONSTITUTION:A vertical hole 2 is bored by rotation of a triple pipe 1 and a jet is injected from the end of the triple pipe 1 to cut the bent root portion of a structural stud 5. Then a stiffener is injected from the triple pipe 1 and substitues for and mixes with drilled earth and sand to form the foundation consolidation portion 3 of the structural stud 5 and form a mix 4 of earth, water and the stiffener. After the triple pipe 3 has been pulled, the structural stud 5 made by an H-steel is suspended down to build its end portion into the unhardended foundation consolidation portion 3. The structural stud 5 is fixed by jigs until the foundation consolidation portion 3 hardens enough to provide strength. Thereby junction of columns and beams can easily and surely be adjusted and the columns and the beams can be directly used, whereby economicity can be enhanced.

摘要： PURPOSE: To increase the efficiency of the earthquake-resisting reinforcement of a foundation by providing a vertical hole on the side of an existing foundation, injecting a hardening agent within a relatively wide range just under the existing foundation through this hole, and forming a columnar foot protection part to reinforce the circumference of a foundation pile. CONSTITUTION: A ground improving vertical hole 2 is drilled from the side of an existing foundation 1, a pipe 3 as a rod is inserted to this vertical hole 2 by use of a constructing machine 6, and a suspension type chemical or a cement solidifying agent or cement milk hardener is injected from the lower end of the pipe 3. At the injection of the solidifying agent, it is sprayed at a super-high pressure to cut the ground, and the soil grains and the hardener are mixed and stirred, or a columnar foot protection part 4 is formed within a relatively wide range just under the existing foundation 1 by substitution. This method can be applied when a pile head is broken by an earthquake. The circumference of a foundation pile 5 is reinforced to reinforce the horizontal supporting force at earthquake. Thus, an earthquake-resisting reinforcement can be executed with a simple method.

摘要： PURPOSE:To enhance workability by arranging a pair of screw reinforcing bars in the axial direction so as to be opposite to the respective surfaces of a reinforced concrete column, and by fixing anchoring members to the upper and lower parts of the respective screw reinforcing bars, and fixing them to the upper and lower flanges by means of bolt connection. CONSTITUTION:A pair of screw reinforcing bars 11 are respectively arranged in the axial direction near to the center of a reinforced concrete column so as to be opposite to the respective surfaces of the column. Two upper and lower anchoring members 3 are fitted to the opposite screw reinforcing bars one end of the upper anchoring member 3 is welded or joined by bolts to the upper flange 1 of steel frame beams, and also one end of the lower anchoring member 3 to the lower flange 1 of the steel structure beams. Thus, the difference in the beam depth in the orthogonal direction or the difference in level of the beams can be easily disposed of.

摘要： PURPOSE: To change a building into a multistoried one by installing a beam to a required floor of a lower layer, composing a rigid framework of a core and an outer circumferential frame or the column of an outer circumferential wall or constituting the rigid framework only of the outer circumferential frame and forming an upper layer floor only in the core and the outer circumferential frame or the outer circumferential wall. CONSTITUTION: A top girder 3 overhangs the core 1 side on the top section of a core 1 and an outer circumferential frame or the columns 2 of an outer circumferential wall, and the top girder 3 and the outer circumferential frame or the columns 2 of the outer circumferential wall are joined through earthquake damping devices 4. Beams 5 are arranged on required floors in the lower layers of a building, and joined rigidly with the outer circumferential frame or the columns 2 mounted on the outer circumferential wall of the building and a rigid framework 6 is constructed. Accordingly, the building can be changed into a multistoried one without spreading the cross section of the core 1. Or the rigid framework is formed only of the outer circumferential frame 2, and the rigidity of the foot of the building is increased.
