Description

  The present invention is a thermal insulation structure between two building structures, one projecting from the other (such as a building ceiling or building wall and a balcony), comprising at least the insulator and the insulator And the reinforcing bars connected to both building structures, and the reinforcing bars are arranged at least in the region above the insulator and from the insulator, in particular horizontally. It is related with what is provided with the tension bar which has projected in the direction, and the compression receiving part arranged in the field below the insulator.

  There are strict regulations regarding seismic resistance in the predetermined field of use of such heat insulation structures. In this case, the well-known thermal insulation structure must absorb additional dynamic loads which are conventionally not considered to be a problem in the case of normal requirements. For example, if the heat insulating structure is configured to support the protruding balcony plate and absorb its own weight and the force and moment acting on the balcony plate from the outside, for example, both building structures contacting the heat insulating structure are different. Accelerating and pulling away due to the impact of an earthquake, resulting in forces and moments acting in the opposite direction, or compressive streaks in the lower insulator region used in general form Force component or moment component in which the protruding building structure acts upward in the vertical direction, contrary to the direction of weight action, due to the swinging motion that cannot be withstood by the tension bars in the upper insulator region alone. Exposed to.

  As a measure for this, it is possible to greatly increase the number of reinforcing bars in the heat insulating member and arrange reinforcing bars at each load acting position or moment acting position. In addition to a significant increase in material costs, the insulation properties also lead to the problem that the insulation properties are clearly degraded by the correspondingly increasing cross section of the reinforcing bars extending between the two adjacent building structures.

  In view of the above situation, the object of the present invention is to use a conventional ordinary structure, but with an appropriate increase in the number of reinforcing bars or an increase in one unit, on the other hand, the static and dynamic of reinforcing bars It is an object of the present invention to provide a heat insulating structure that avoids an increase in the cross section of the reinforcing bars extending between the two adjacent building structures, which avoids excessive excess specifications and, on the other hand, impairs the heat insulating properties.

  A heat insulating structure between two building structures, one of which protrudes from the other, comprising at least an insulator and a reinforcement that penetrates the insulator and is connected to both building structures. The reinforcing means includes at least a tensile bar disposed in the upper region of the insulator and protruding from the insulator, and a compression receiver disposed in the lower region of the insulator. In order to solve the above problems, in the present invention, at least one supplementary insulator located on the same row as the insulator is disposed adjacent to the insulator in the horizontal direction. The supplementary insulator has a supplementary tension bar provided in the region of the lower half of the supplementary insulator to counter seismic loads, the supplementary tension line in the horizontal direction It protrudes from the serial insulator.

  Combining the conventional insulation structure used in the past with a supplementary insulator having only a supplementary tension bar in the lower insulator region provided to counter seismic loads has the following advantages in particular: Arise. Conventional ordinary thermal insulation structures are conventionally used to absorb normal static and dynamic loads. Therefore, the supplementary insulator adjacent to the normal heat insulation structure in the same row does not affect the determination and construction of the conventional normal heat insulation structure. This simplifies the design, dimensioning and incorporation of ordinary thermal insulation structures.

  Supplementary insulation adjacent to the same row as the normal insulation structure is captured in the lower region of the insulation through the compression receivers and shears that normally occur in this height region, which occurs during seismic loads. Alternatively, only the supplementary puller is needed to absorb the tensile force that cannot be transmitted. Preferably, the pulling bar, usually located in the insulator, may also function for compressive and / or shear force transmission in the region of the upper insulator half in the event of an earthquake. This eliminates the need for the supplemental insulator to have a separate reinforcement bar other than the supplementary pull bar. As a result, the supplementary insulator joined to the supplementary tensile bar alone cannot take on or secure a sufficient function for both seismic load and normal load. It is clear that the task imposed on the supplementary insulator can only be achieved when it is in conjunction with the adjacent normal insulation structure.

  With respect to the supplementary tension bars, these supplementary tension bars are known per se, but are preferably constructed in the form of rods and are inserted deeply into the building structure to be adjacent and these buildings. In order to achieve a correspondingly good fixing in the structure, it may be projected outwardly via a supplementary insulator.

  The supplementary pulling bar further has a plate-like load introduction shape at least at the end on the end face side, and this load introduction shape is parallel to the plane of the insulator, particularly in a substantially vertical plane. It extends to. In other words, one form of the load-introducing shape part is a rib-like member that expands in the transverse direction of the muscle, and this configuration that receives force is clearly shortening the length required for force introduction. Is done. This is suitable, for example, when there is another building structure such as a support that is not allowed to insert the supplementary pull-in bar within the installation range provided for the supplemental pull-up bar.

  In a further preferred embodiment, the supplemental insulator has two supplemental tension bars juxtaposed with a horizontal spacing. Furthermore, the supplementary insulator comprises only two supplementary pulling bars, so that the task imposed on the supplemental insulator is fully achieved.

  If a second insulator in the horizontal direction adjacent to the supplementary insulator and in the same row as the supplementary insulator and having a tension bar and a compression receiving part is arranged, the continuous row of normal insulation structures is particularly Interrupted by a short section of supplemental insulation with only two pull bars.

Other components and advantages of the present invention will be described below based on the illustrated embodiments.
FIG. 1 shows a heat insulating structure 1 of the present invention. The heat insulating structure 1 is composed of a combination of two conventional heat insulating structures 2 of a conventional type and one heat insulating structure 3 provided to resist an earthquake load. The ordinary heat insulating structure 2 includes an insulator 12 and a reinforcing means. The reinforcing means is disposed on the insulator 12 and extends through the insulator 12 in a plane substantially perpendicular to the longitudinal extension of the insulator 12, and partially extends from the insulator 12. It protrudes. As the reinforcing means, in the ordinary heat insulating structure 2 in the embodiment shown in FIG. 1, the upper pulling bar 4 extending in the horizontal direction and the lower compression receiving portion arranged in substantially the same manner as the insulator 12. 5 and a shear line 6 that extends through the insulator 12 from the top to the bottom and is curved so as to have a step in the vertical direction outside the insulator 12. As is apparent from FIG. 1, these reinforcing bars are provided in correspondence with a grid that is adaptable or adaptable to a predetermined individual load. Such an insulator of the heat insulating structure 2 is usually divided in the horizontal direction in order to facilitate the attachment or positioning of the reinforcing bars in the region of the reinforcing bars.

  A supplementary insulator 14 is arranged between the two ordinary heat insulating structures 2. The supplementary insulator 14 extends in the same row as the thermal insulation structure 2 so as to fit the vertical plane of the adjacent insulator 12 and further extends only into the lower region of the insulator 12 to accept seismic loads. It has a tension bar 15. This supplementary tension bar 15 is generally parallel to the tension bar 4 of the heat insulating structure 2 but extends in a lower height region.

  The simplified front view of FIG. 2 shows a normal insulation structure 2 as well as a supplementary insulator 14 having supplementary tension bars 15 interposed between the two thermal insulation structures 2. The supplementary insulator 14 and the supplementary tension bar 15 form a heat insulation structure specially prepared to counter seismic loads.

  It can be seen from FIG. 2 how reinforcing means in the form of tension bars 4, compression receivers 5 and shear bars 6 are provided for the heat insulating structure against this seismic load. In particular, the compression receiver 5 that resists additional seismic loads has no or little other function, in particular, the tension bar 4 has a compressive force component and a shear force component generated during an earthquake. Help to catch. This function is limited, at least in calculation, to the pulling bars arranged adjacent to the thermal insulation structure 3 that resists this seismic load.

  It is very easy to determine the calculation and dimensions of the thermal insulation structure 3 to counter seismic load without changing the structure itself of the ordinary thermal insulation structure 2, and the installation or installation of these thermal insulation structures 3 for seismic load Assembling can also be carried out in a quite simple manner by joining one seismic load heat insulating structure 3 after the ordinary heat insulating structure 2 is attached or assembled.

  In summary, with a simple means and minimal additional equipment, the normally insulated structure 2 can be used to counter seismic loads. In this case, according to the present invention, the reinforcing bar 4 of the normal heat insulation structure 2 must be taken over by the heat insulation structure 2 against the seismic load. 2 adjacent reinforcement bars 15 can be imposed.
