Description

本発明は、ALCパネルなどを、建物のH型鉄骨小梁に取り付け、屋根や床が構成されている既存建築物において、使用した屋根パネルや床パネルに、経年劣化や損傷などによる強度低下やたわみ量の増加などが認められた場合に行う屋根パネルまたは床パネルの補強方法、補強構造および補強用支持金具に関する。   The present invention attaches an ALC panel or the like to an H-shaped steel beam of a building, and in an existing building in which a roof or a floor is configured, the roof panel or floor panel used has a reduced strength due to aging or damage. The present invention relates to a roof panel or floor panel reinforcement method, a reinforcement structure, and a reinforcing support bracket, which are performed when an increase in deflection is recognized.

従来、例えば、ALCパネルなどを、建物のH型鉄骨小梁に取り付け、屋根や床が構成されている既存建築物において、使用した屋根パネルや床パネルに、経年劣化や損傷などによる強度低下やたわみ量の増加などが認められた場合、その対策としては、屋根パネルまたは床パネルの取替えや、支持梁の追加などを行うことが一般的である。   Conventionally, for example, in an existing building where an ALC panel or the like is attached to an H-shaped steel beam of a building and the roof or floor is configured, the roof panel or floor panel used has a reduced strength due to aging or damage. When an increase in the amount of deflection is recognized, it is common to take measures such as replacing roof panels or floor panels or adding support beams.

屋根パネルまたは床パネルの取替えとして、例えば、特開平9−195431号公報には、剛性を向上させるALCパネル床構造の施行方法が記載されている。このような対策の場合、屋根や床においては、必ず上部に仕上げが施されており、屋根パネルまたは床パネルの取替えに際して、仕上げの撤去が必要であるという問題や、屋根パネルまたは床パネルの解体や搬入などにも手間がかかるという問題がある。   As a replacement of a roof panel or a floor panel, for example, Japanese Patent Laid-Open No. 9-195431 describes a method for implementing an ALC panel floor structure that improves rigidity. In the case of such measures, the roof and floor are always finished at the top, and there is a problem that the removal of the finish is necessary when replacing the roof panel or floor panel. There is a problem that it takes time and trouble to carry in.

一方、パネル支持梁の追加においては、質量の大きいパネル支持梁の取付けに際して、重機などが必要であったり、既存梁への加工が必要であるなど、工事が大掛かりになるという問題がある。   On the other hand, the addition of a panel support beam has a problem that a heavy machine or the like is required to attach the panel support beam having a large mass, or that an existing beam is required to be processed.

また、該当物件が、稼動中の工場や、共同住宅などの場合、工事が実施可能な期間や時間帯、あるいは、使用可能な機械や設備に制限があったり、溶接作業などが制限される可能性が極めて高く、補強を行うことが実施不可能と判断されるケースも見受けられる。   In addition, if the property is a factory or apartment house that is in operation, there may be restrictions on the period and time period during which construction can be performed, the machines and equipment that can be used, and welding work may be restricted. In some cases, it is extremely difficult to carry out reinforcement.

特開平9−195431号公報Japanese Patent Laid-Open No. 9-195431

本発明は、ALCパネルなどを、建物のH型鉄骨小梁に取り付け、屋根や床が構成されている既存建築物において、使用した屋根パネルや床パネルに、経年劣化や損傷などによる強度低下やたわみ量の増加などが認められた場合に、上部仕上げの撤去、重機の使用または既存梁への加工の必要がなく、さらに、溶接を用いることなく、下側から実施することが可能で、建物用途に影響されにくく、比較的、簡易な工事で済み、かつ、強度的に信頼できる補強方法を提供することを目的とする。   The present invention attaches an ALC panel or the like to an H-shaped steel beam of a building, and in an existing building in which a roof or a floor is configured, the roof panel or floor panel used has a reduced strength due to aging or damage. When an increase in the amount of deflection is observed, it is not necessary to remove the upper finish, use heavy machinery or process existing beams, and can be carried out from the bottom without using welding.

It consists of a nut to be tightened and a bolt, and is provided with a notch having a width dimensioned so that the base of the presser fitting can be inserted into one open end of the horizontal piece and the nut does not come off, The other open end is provided with a screw hole to which the bolt can be tightened.

具体的には、前記水平片の一方の開放端部に設けられた前記切り込みに、前記押さえ金具を横方向から挿入し、前記基部を前記ナットにより回し締めすることにより、前記押さえ金具が前記金具本体に固定される。これにより、前記第1の垂直片と第2の垂直片の上端部と、前記水平片に平行に(すなわち、該第1の垂直片と第2の垂直片の上端部に平行に)伸長する前記押さえ部とにより、H型鉄骨小梁の上側フランジを挟んで、前記金具本体を該H型鉄骨小梁に固定することができる。さらに、前記他方の開放端部より前記金具本体に挿入された補強鋼材を、前記ボルトを前記ネジ孔に回し締めすることにより、前記金具本体内に固定するとともに、該補強鋼材により前記H型鉄骨小梁に支持された屋根パネルまたは床パネルを支持させることができる。   Specifically, the press fitting is inserted into the notch provided at one open end of the horizontal piece from the lateral direction, and the base is turned and tightened with the nut, whereby the press fitting is attached to the fitting. Fixed to the body. Accordingly, the upper ends of the first vertical piece and the second vertical piece extend in parallel to the horizontal piece (that is, parallel to the upper ends of the first vertical piece and the second vertical piece). With the pressing portion, the metal fitting body can be fixed to the H-shaped steel beam with the upper flange of the H-shaped steel beam interposed therebetween. Furthermore, the reinforcing steel material inserted into the metal fitting body from the other open end is fixed in the metal fitting body by turning the bolt into the screw hole, and the H-shaped steel frame is fixed by the reinforcing steel material. A roof panel or floor panel supported by the beam can be supported.

なお、前記切り込みは、横方向から前記押さえ金具を挿入可能としているが、前記押さえ金具を前記金具本体にナットにより固定できればよく、前記水平片の一方の開放端部に通孔を設けることにより、代替させてもよい。   In addition, although the said cutting makes it possible to insert the press fitting from the side, it is only necessary to fix the press fitting to the fitting main body with a nut, and by providing a through hole in one open end of the horizontal piece, It may be substituted.

また、屋根パネルまたは床パネルの下側面の角に面取りが設けられている場合には、前記押さえ金具の押さえ部は、該面取りと前記H型鉄骨小梁の上側フランジとの間の隙間に差し込むことが可能となるように、寸法付けされていることが好ましい。   Further, when chamfering is provided at the corner of the lower surface of the roof panel or floor panel, the pressing portion of the pressing metal fitting is inserted into the gap between the chamfering and the upper flange of the H-shaped steel beam. It is preferably dimensioned so that it is possible.

本発明に係る屋根パネルまたは床パネルの補強方法は、屋根パネルまたは床パネルを支持するH型鉄骨小梁の上側フランジに、前述の小梁部の補強用支持金具を固定し、小梁部の補強用支持金具に、補強鋼材を支持させることにより、該補強鋼材により屋根パネルまたは床パネルを支持する。さらに、前記H型鉄骨小梁の上側フランジの下側面に当接させた前記第1の垂直片および第2の垂直片と、上側フランジの上側面に当接させた前記押さえ金具の押さえ部とにより、上側フランジを挟むように、前記水平片の切り欠きに挿通している前記押さえ金具の基部に前記ナットを回し締めし、前記ボルトのある側から水平方向に差し込まれた補強鋼材が、屋根パネルまたは床パネルの下面を押さえるように、前記ボルトを前記ネジ孔に対して回し締める。   The method for reinforcing a roof panel or floor panel according to the present invention is to fix the above-mentioned reinforcing support bracket for the small beam portion to the upper flange of the H-shaped steel beam that supports the roof panel or the floor panel. By supporting the reinforcing steel material on the reinforcing support metal, the roof panel or floor panel is supported by the reinforcing steel material. Further, the first vertical piece and the second vertical piece brought into contact with the lower side surface of the upper flange of the H-shaped steel beam, and the holding part of the presser fitting brought into contact with the upper side surface of the upper flange, By tightening the nut to the base of the presser fitting inserted through the notch of the horizontal piece so as to sandwich the upper flange, the reinforcing steel material inserted in the horizontal direction from the side with the bolt is a roof. The bolt is turned and tightened against the screw hole so as to hold the lower surface of the panel or floor panel.

なお、前記押さえ金具の押さえ部を、屋根パネルまたは床パネルの下側面の角の面取りと、前記H型鉄骨小梁の上側フランジの上側面との間の隙間に差し込むようにすることが好ましい。   In addition, it is preferable that the pressing portion of the pressing metal fitting is inserted into a gap between the chamfered corner of the lower surface of the roof panel or floor panel and the upper surface of the upper flange of the H-shaped steel beam.

また、前記補強鋼材には、所定水準の受け材支持部を少なくとも片側に備え、平行して配置された補強鋼材の受け材支持部の上に両端を載せた受け材が、補強鋼材と協働して屋根パネルまたは床パネルを支えて補強することが望ましい。   Further, the reinforcing steel material includes a receiving material support portion having a predetermined level on at least one side, and the receiving material having both ends placed on the receiving material support portions of the reinforcing steel material arranged in parallel cooperates with the reinforcing steel material. Thus, it is desirable to support and reinforce the roof panel or floor panel.

本発明に係る屋根パネルまたは床パネルの補強構造は、屋根パネルまたは床パネルの両端が2本のH型鉄骨小梁により支持されている構造において、前記パネルの下側より前記H型鉄骨小梁のそれぞれの上側フランジに固定される補強用支持金具と、該補強用支持金具に固定され、前記H型鉄骨小梁間にわたされ、前記パネルを支持する補強鋼材とからなる。当該構造において、前記補強鋼材が複数配置され、該補強鋼材の略中間部に少なくとも1つの受け材支持部が設けられており、該受け材支持部に載置された受け材が、前記補強鋼材間にわたされ、補強鋼材と協働して前記パネルを支持するようにしてもよい。   The roof panel or floor panel reinforcing structure according to the present invention is a structure in which both ends of the roof panel or floor panel are supported by two H-shaped steel beams.
