    Six kinds of stones, which are expansible by heat, were tesed and the heat expansion characters were obtained in stone itself and tile specimens made with the crashed stones. Shale was found to be the most preferable to make aggregate, however it had tittle surface melting and released its foam near surface. In order to improve this quality, the authors carried out the experiments on 18 mixes of clay, pottery stone and shale. The mixing of shale and pottery stone in 90 : 10 was found as the best among them. An aggregate was made with the conbination. The main results obtained on the aggregate were as follows : The specific gravity was 1.6-1.8. The water absorption was 0.8% in 24 hours. The strength of the gravel was greater than that of an artificial aggregate found on the market (A.L.A.) according to the plunger tests. When the A.L.A. gravel in concrete was replaced by the new aggregate : The weight increase of 8% resulted. The tensile strength and the increase rate in compressive strength to c/w ratio became lower. The higher compressive strength was achieved when c/w ratio was under 2.0. The water avsorption, water permeation and drying shrinkage in length became amaller. The modulus of elasticity showed higher value and it was the same as that of the river gravel concrete.

    In the Previous paper, the author reported the theory of the Chain Construction with Elastic Joints as well as the results of the experimental study on the Sandwich Curtain Wall. It was shown that the theory could be appied to the wall with close approximation in its vertical direction. In the horizontal direction however it was found isotropic. The present paper-deals with an experimental study on deflection of the Rectangular Plate composed of istoropic plates and elastic joints. The test plates are constructed with aluminium-panels and rubber-strings. Each and every edges of those test plates are simply supported. The results obtained under vertical load are as follows : 1. The deflection-form of the plates along the y-axis is invariable regardless of Iy : Ix. The deflection-form at 1-1' section is similar to that at 5-5' section. 2. The values of δ'/δ along x-axis are 1.50 all together, at 1-5 section it is about 1.43 however. 3. The deflection-value of the Chain Plate with Elastic Joint is about 2.19-2.30 as large value Elastic Plateis.

    To keep the cost of the wiring of electrical equipments in a building economical, we have hitherto considered it is fundamental that substations, switchboards, and panel boards required should be installed close by load centers concerned. There has been a sharp accentuation of interest in and effort on, economical planning of interior wiring, i.e. to keep electrical equipment installation to load centers in close layout which would minimize the wiring costs. But our practical experiences show that it is very difficult to keep layout of electrical equipments close by load centers in a building as satisfactorily as electrical engineers desire by so many troubles. In some case, close layout is difficult to be carried out as planned by electrical engineers being change of planning necessary for close layout impossible in due time of construction schedule, nothing left except best alternative wiring to be planned. In another case, having time enough to plan close layout and to propose economical layout of switchboads and panel boards to an architect in charge of the building design, and very often no approval from an architect, because of no numerical values specified for close layout as measuring indices in evaluating close layout characteristics. Accordingly, unsatisfactory layout of electrical equipments and rather not economical wiring are carried out in a building, and very often in such cases, electrical engineers are allowed only to seek out the best layout within the limited conditions of the building plan given by an architect. In case of small total floor area, cost-up of wiring according to the unfit layout of electrical equipments to the load center, amounts not to so much as compared with the optimum wiring. But in case of large total floor area, cost-up brought by unfit layout amounts to so much as not negligible. If we can express cost-up rates in numerical terms according to off-distances from the load center considered desirable, we can have measuring indices in numerical terms sufficient to evaluate, and we can change some parts of building plan by positive recommendation effective to carry out general coordination between electrical engineers and an architect. And we can have economical layout of switchboards and panel boards. We must assign quantitative numbers to all the significant factors relative to the economical layout of switchboards and panel boards.

  • RESEARCH ON WEARING OF THE FORMER OSAKA CENTRAL TELEGRAPH OFFICE BUILDING : Part 1 : Reinforced Concrete and Steel Sash : Part 2 : External and Internal Finishing Materials

    In this paper, a research is reported on wearing of the building which was demolished after about forty years. We have tried to catch the fundamental data for building maintenance by this research. 1. Concrete; As the result of concrete tests by a non-destructive method (Schmidt-Hammer) and a destructive method (Core-boring), we have recognized that the compressive strength was higher than the anticipated one by certifications (135kg/cm^2), and the concrete job was not so poor in those days. The mean depth of neutralized plaster was 20mm and agreed with the value of "Pastyear-Neutralization formula". 2. Reinforcing bar; The steel aging was not recognized and its tensile strength didn't reach to the yield point even at a concrete crack-width 1.5mm. 3. Steel sash and shutter; By sunshines and usual winds, the aging difference between northern and southern side was great. Concerning to steel shutters, we were able to operate them very well in spite of few repairs during many years. 4. Ceramic tile; Tiles on the external wall were semi-porcelain by reason of colour, so the absorption ratio was very high. But there was no damage for frost, then it is reliable that the semi-porcelain tile can be used as well as the porcelain one in Kansai district. More than 80% of total wall tiles didn't adhere with the concrete, caused by corrosion of steel sashes. 5. Linoleum; As the result of endurance test and abrasion test, etc., its aging was generally little. 6. Non slip of a stair case; The wearing thickness of non slip made of bronze, were measured and then we recognized the point of 45cm apart from the handrail was most worn away. 7. Others; Brick and other materials were examined and researched.

    We tried to survey the locality constitution of SHIMA town from the following view point. The relationship of mutural dependance in shopping are determined by the pattern of the locality arrangement and the economical function between localities. We studied the trffic afairs, the statics of shops in 1964, and the shopping tendency. We delivered the investigation cards to students of SHIMA middleschool, which inqires the place of shopping, the means of traffic and the reasons of shopping. SHIMA town is divided by 4 sections which were former villages before 1955. and is situated at the end of ITOSHIMA peninsula. It is far form the main rout but bus rout extend to each sections from adjoining town MAEBARA. Most of localities are classified into agricultural and fishing type. Shops sell the daily neccesities, for example, bread and cakes, provisions, row fiishes, liqor and tobaccos. The inhabitants depend them upon the shops at SHIMA town. The durable goods, for example, furnitures, meats, books and magazines, watches and glass, medecines, cloges, radio and TV sets, and clothes are few sold here. They depend them upon the shops at MAEBARA town. In conclusion, it is considered that SHIMA town has not a central locality, and MAEBARA town play an important part in daily life of inhabitants here.
