Description

[Detailed description of the invention] A6 Objective of the invention (industrial application field) The present invention is used in the manufacturing and construction industry of expansion joints for construction materials, and is installed on the floor of parallel buildings or on the rooftop river bed frame. This relates to an expansion joint with high waterproofing effect that ensures the end treatment of the tarpaulin sheet and prevents water from entering the inner layer of the building structure.

(Prior Art) As shown in the conventional eaves cap seen in Japanese Patent Application Laid-open No. 56-16756, as a method of waterproofing concrete buildings, the eaves facing the indoor side of the main body covering the upper surface of the corner portion of a concrete building is used. At the top of the building, we used a cap that was formed by installing a waterproof layer support wall extending indoors in an upward-standing manner on the outside. This cap was fixed to the top surface of the corner part of the Hunkreet building, and then the waterproof layer was applied to the building. A method has been invented in which the ends of the waterproof layer are overlapped with the support wall for the waterproof layer, a waterproof presser is applied to the outer surface of the waterproof layer layered on the supporting wall that stands up on both sides of the diameter, and the waterproof presser is screwed to the capboard.

This waterproofing method for buildings with eaves caps is such that the concrete frame of the single building frame is covered with an eave cap that has a rising waterproof layer supporting wall, and the roof is covered with an eaves cap that has a rising waterproof layer support wall. The purpose of this project is to increase the durability of concrete buildings with vertical rises.

(Problems to be Solved by the Invention) However, the conventional waterproofing construction method described above is based on the eaves of a single-sided building frame, and is not a frame that expands and contracts in the gap between each frame, but a rise in the concrete frame. Although it is possible to increase the durability of the part by reinforcing it with eaves caps, etc., the strength of the rooftop walking frame or floor walking frame due to fluctuations such as expansion and contraction, tilting, etc. of the building frames installed side by side can be improved. The problem is that it is impossible to close the gap between the floor structures in a substantially planar manner and to prevent the intrusion of rainwater, etc. into the inner layer of the floor structure by including the rising end of the waterproof material in the inner layer of the floor structure. Met.

The present invention has been made in order to solve the above-mentioned conventional problems, and includes grooves for receiving waterproof material on the side of the fixed mounting member that constitutes the expansion joint of the rooftop walking frame and floor walking frame of a building. A floor walking frame is provided in which the ends of waterproofing materials are provided in the receiving grooves and are affixed upwardly from the inner layer of the floor frame towards the surface of the fixed attachment member, thereby providing good protection against rainwater and general water intrusion prevention. The purpose is to provide an expansion joint.

4. Structure of the Invention (Means for Solving the Problems) The expansion joint according to the present invention to achieve the above object, as shown in the embodiment, is a construction for rooftop walking frames 1. 2. It is composed of a fixed mounting member 5.6 provided in the substantially planar gap a of the floor frame 3.4 of the floor walking frame, and a cover material 14 disposed thereon, which allows for expansion, contraction, and tilting between the frames. At the expansion joint that accommodates fluctuations such as longitudinal movement, the fixed mounting member 5.6 (11 Receiving groove 21.21 that encloses the end portion 19 of the waterproof material 20 that has been erected and pasted.
It is a configuration with.

(Function) When using the expansion joint according to the present invention, as shown in FIG. After fixing the fixing attachment members 5.6 of the cover material 14 that closes the gap a to the ends of the frame, fixing of the cover material 14 forms the fixing attachment members 5.6 on the non-gap side edges of the fixing attachment members 5.6. The raised end 19.19 of the waterproofing material 20, which has been laid in advance on the floor frame 3.4 and raised toward the surface of the fixed attachment member 5.6, is enclosed in the receiving groove 21.21, and then fixed. Pass the water stop plate 9 between the mounting members 5.6, pass the cover material 14 to the fixed mounting member 5.6, fix the cover material 14 to the fixed mounting member 5.6, and then A finishing material 23 such as mortar is applied to the floor frame 3.4, and tooling 24 is applied to the side edges of the fixed mounting members 5.6 to prevent rainwater from entering even if the frame changes, and to seal the gap between This ensures that room a is closed.

C9. Effects of the Invention The present invention relates to an expansion joint, as described above, which includes a fixed mounting member provided in a gap between the floor frames of a rooftop walking frame and a floor walking frame in buildings installed side by side, and a fixed attachment member placed therein. A receptacle containing an end of a waterproof material that is affixed upright from the inner layer of the floor structure toward the surface of the fixed mounting member on the non-gap side edge of the fixed mounting member in the expansion joint constituted by the cover material. Because it has a structure with grooves, it is possible to reliably prevent accumulated rainwater from entering the inner layer of the corresponding floor framework, and when installed on a rooftop walking framework, the roof will be smooth. For example, when an expansion joint is installed between buildings such as a school in the city center, it can be effectively used as a rooftop over a wide area without obstacles, and it can also be used as an open corridor. It is fully waterproof even in areas where water is used, and in this case, it is completely enclosed by the receiving groove that forms the raised end of the waterproof material installed in the layer of the floor structure, so water flowing onto the floor is prevented. This has the unique effect of preventing water from entering the building frame, providing waterproof protection to the building, and preventing freezing accidents to the building frame.
