Abstract

<P>PROBLEM TO BE SOLVED: To provide a method for constructing a steel wooden building, in which conventionally construction is affected by weather, hard to complete construciton within a scheduled period, and an earthquake resistance needs to be enhanced, inventory of the members can not easily attained, and the work efficiency of unsafe external scaffold work need to be improved for reducing costs. <P>SOLUTION: Members are worked by a standard facilitated working for a framework, and the worked members are kept in stock. The members are assembled for each span on an assembly stand in a yard to finish to external walls, and the external walls are erected by a crane vehicle. Since there is no work on a scaffold for the external wall, safety is high and the effect of weather is less, and a reduction in construction period and the safety reduce cost. A highly earth-resistant building can be constructed by combining steel and wood. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention relates to a wooden structure of steel and wood with a combination of steel and timber and a reduced construction period.

  In traditional wooden buildings, building engineers paint and process drawings for each building. (There is pre-cut processing) When the processing is completed, it is carried on site and built. If it continues to rain, work will be carried out on an external scaffold that will extend the construction period, and the joint will be reinforced with hardware, but it cannot be said that it is sufficient for earthquake resistance, and the work on the scaffold is dangerous and the work efficiency is poor .

  The conventional marking and processing for each building cannot be stocked by processing the parts. In the conventional method, assembly and exterior wall finishing are impossible in the workplace, etc., and it depends on the weather and the construction period cannot be shortened.

  The problem to be solved is that it is impossible to shorten the construction period because the wooden frame processing and inventory are not possible, the seismic reinforcement is not sufficient, the work on the external scaffolding is dangerous and work efficiency is poor, and work in long rainy weather However, there is a problem that the construction period is prolonged.

Means for solving the problem

  The present invention is intended to solve such a conventional problem, and the construction period can be shortened and safety can be secured without weakening the members of the wooden building by further improving the earthquake resistance and simplifying the shaft assembly. The construction method is provided.

  In the present invention, in order to further improve the earthquake resistance by combining the steel strip and the equilateral mountain-shaped steel into the wooden structure, the combination of the steel material and the wood is utilized to secure the safety and the long-term service life by tightening the joint portion. The feature that the shaft assembly and the outer wall finish are completed in the workshop leads to shortened construction period and low cost.

The invention's effect

  According to the present invention, simple processing and stocking of parts can be performed. Because of simplicity, assembly is possible even without being a construction engineer. Tightening of joints improves seismic resistance. Since there is no shortening of the construction period and external scaffold work, safety and efficiency are good, and the above results in low cost.

  In the steel-wood structure of the present invention, the foamed polystyrene for the cavity of the anchor Ha is installed on the column base of the basic K form shown in the detailed diagram of FIG. To do.

  A round shallow hole ma is provided at the required column position of the base of the wooden frame, a base D is provided with through holes at the center and both ends at the width of the column diameter, and a high nut Tn is provided at one end of the steel strip (flat bar). (Coupler) welded together, steel strip 1F with vault hole ba at the other end, round short hoz mh at both ends of the column, high nut accommodation holes at one end, core grinding from one side to the center The steel strip is fitted into the groove of the grooved column, and the fixed steel column H1 is cut and the steel strip width is cut at the center position of the required column on the surface of the angle steel (angle) with the thickness of the steel strip 1F. The angled steel Da is provided with the required round shallow hole ma on one side of the body difference, the through hole is provided on the left and right sides of the column width from the center of the hole, and the angle difference is provided on the other side with the shank groove As fitted into the angled steel. Insert the part without steel hole into the groove and fix the lower body difference D1, the thickness of the steel strip at both ends of the required length of the steel strip A steel strip that has a bent length of 2 mm, a striped steel Sb with dozens of screw holes in the center, and a striped groove with a strip steel width and thickness on the plane of the two pillars. The difference Ms, the tensile force and the compression force are different in one direction.

  For the assembly of the shaft assembly, the base D is placed on the standard assembly base, the high nut flange on one end of the column H1 is inserted into the base round shallow hole ma, and the round washer Mw is inserted into the eye vault Ib and temporarily fixed. The body difference D1 is inserted and fixed with the angle stopper pin ap, and the eyeball is finally tightened. If the stud M is fixed, the wood bars Ms are fixed, and the band steel Sb is fitted into the shank groove and fixed with screws, the first-floor one-span shaft is assembled, and each required span is assembled at the work site. First floor steel wooden frame.

  The required bottom round hole shallow hole mh is provided on one side of the body difference, the body difference tightening vault Db hole is provided on both sides, the bottom round hole is scraped off, the upper body difference D2 of Fa, and the one end vault hole Fba processing of the steel strip The bar Cb is welded to the other end, and the steel strip 2F of the high nut Tn welded joint is fitted into the column of the both ends round short hozo mh groove processing and fixed, and the second hole column H2 is fixed. Girder and beam Kh, with steel strips FB, girders and beams provided with round shallow holes and vault through holes at the column positions.

Columns are placed on the assembly standard table, the upper body difference D2 is inserted, the girder is inserted into the tenon, the eye vault Ib is inserted into the band steel FB hole, and tightened through the girder Kh. Fixing is based on the first floor, and the second span span shaft group and the required span shaft groups are assembled.

  Apply the bond to the first and second floor pillars of the assembly and the pillars, bond the structural plywood Kg and nail it at 12 cm intervals, attach the sash frame to the required opening, and apply waterproof paper, Each span shaft group with the outer wall siding S lifted up is carried to the site.

  Assemble the wire hole ba of the first-floor frame span and hang it with a crane car. After each span is assembled, lay and fix the first floor panel, lay and fix the second floor panel. , Make it a two-storey scaffold. On the second floor assembly, lay the wire on the axis vault 1b of the shaft span and build it by lifting it with a crane truck. After the building is finished, the roof panel Yp is laid and fixed, and the insulation is laid and fixed on the waterproof paper. Make a colonial co. A construction method for a steel wooden structure characterized by the fact that the foundation Ka is filled with mortar and completed with joint caulking C, which is completed when the internal construction is completed, and no scaffolding for external walls is required.

  In the above-mentioned invention, it is possible to finish machining and finishing to the outer wall in the workplace with simple standard processing, there is little influence of the weather, and there is no work on the scaffold outside, safety and work efficiency are good, steel and wood Since the combination of these is high in earthquake resistance and shortening the construction period leads to low cost, the applicability is great.

It is a perspective view of a shaft assembly. It is a section detailed drawing of a foundation, a foundation, a pillar, a trunk difference, a girder, a floor panel, and a roof panel. It is a shaft assembly surface view.
