つた。 Generally, in this type of expansion joint, a cover member is attached to the front and back sides of the gap between opposing building frames via support members to cover the gap, and also to cover the gap between the building frames. Some have a structure in which a protective member is provided to prevent rainwater, dirt, dust, etc. from entering the ground. However, since this protective member has conventionally been made of materials such as synthetic resin such as styrofoam, or synthetic rubber, it is easily melted by high temperatures, and therefore, in the event of a fire, etc. It was impossible to prevent smoke and the like from entering through the gaps.

布しておけば一層その固定像体が確実になる。 The protection member 2 is made of a flexible, stretchable material that has fire resistance and heat resistance. That is, the protective member 2 is formed by adding a small amount of organic binder to fine flex bulk fiber and super heat-resistant alumina fiber, and is highly flexible and has excellent fire resistance and heat resistance. When installing the protective member 2 in the frame gap S, first, in order to prevent the flexible protective member 2 from being deformed after installation, it is necessary to set equal intervals inside the protective member 2 as shown in Fig. 3a and b. The reinforcing pins 3, 3, 3, . . . are buried together, and compression bands 4, 4, . ，
4 maintains the protective member in a compressed state. After the protective member 2 is placed in the gap S between the building frames 1, 1, the compression bands 4, 4... wrapped around the protective member 2 are cut using scissors, and the protective member Due to its elasticity, the compressed state of the protective member 2 is released and the protective member 2 expands, thereby allowing the protective member 2 to be firmly attached to the gap S. In the above case, if an adhesive is applied to the side surfaces of the building frames 1, 1 and both sides of the protective member 2, the fixation of the image becomes even more reliable.

が損なわれることがない。 As explained in detail above, according to the expansion joint according to the present invention, a flexible and expandable fire-resistant and heat-resistant protective member is disposed in the gap between opposing building frames. It is possible to reliably prevent smoke, flame, etc. from entering through the above-mentioned gap, thereby preventing danger to the body, and long reinforcing pins are buried inside the above-mentioned protection part at regular intervals in the width direction of the protection member. Therefore, the installation strength is high, and even if the building frame is relatively displaced due to vibration or uneven settlement, the protection member will not be deformed and the fire prevention and flameproof functions will not be impaired.
