Description

[Detailed description of the invention] This invention relates to the improvement of joint materials for building panels.

As shown in Fig. 1, this type of conventional joint material is extruded from solid rubber into a hollow shape with a substantially rectangular cross section, and has a plurality of sealing lips 13 protruding from both sides and a depression 14 on the top surface. It is set up.

As shown in FIG. 2, when this joint material is inserted into the groove 12 formed on the outer wall 11 side of the joint 10 of the building panels 8 and 9, the depression 14 of the joint material is further folded in and stands out as a streak. Therefore, it spoils the aesthetic appearance,
In addition, especially in the case of horizontal horizontal joints, there is a problem that dirt such as dust tends to stay in the depressions 14.

This invention was made for the purpose of solving the above-mentioned conventional drawbacks and improving the sealing performance.

An embodiment of this invention will be explained based on FIGS. 3 and 4.

Reference numeral 1 denotes a joint material, which is made of synthetic rubber or synthetic resin and has a substantially rectangular cross section, and has a hollow joint main body 3 with a plurality of seal lips 2 protruding upward from both sides thereof;
A decorative lip 5 having a substantially T-shaped cross section and projecting from the center of a depression 4 provided on the top surface of the joint body is integrally extruded.

Further, the flange portion 6 of the decorative lip 5 is curved upward in a convex manner, and a color layer 7 is provided on the upper surface.

Therefore, when the joint material 1 is inserted into the joint material attachment groove 12 formed on the outer wall 11 side of the joint 10 of the building panels 8 and 9, the joint body 3 is compressed in the lateral direction by the end surfaces of the panels 8 and 9. The uppermost lip 2a of the plurality of seal lips 2 rises upward and pushes up the flange portion 6 of the decorative lip 5.

Therefore, the flange portion 6 changes from an upwardly convex state to a horizontal state so as to close the groove 12 and coincide with the outer wall 11 of the building panels 8 and 9.

As mentioned above, in this invention, the joint material 1 used for the joint 10 of the building panels 8 and 9 has a substantially rectangular cross section with a plurality of upward sealing lips 2 protruding from both sides thereof, and a depression 4 on the top surface. A decorative lip 5 having a substantially T-shaped cross section is protruded from the center of the depression, and a groove 12 for attaching joint material to building panels 8 and 9 is provided.
When the joint material 1 is inserted, the joint main body 3 is laterally compressed by the end faces of the panels 8 and 9, and the uppermost lip 2a of the plurality of seal lips 2 rises upward, resulting in the flange portion 6 of the decorative lip 5. is pushed up, and the uppermost lip 2a and flange portion 6 are formed so that the flange portion 6 changes from an upwardly convex state to a horizontal state, closing the groove 12 and aligning with the outer wall 11 surface of the building panels 8 and 9. This is what I did.

According to this invention, when the joint material 1 is used at the joint 10, the decorative lip 5 closes the joint 10 so that it is flush with the outer wall 11 of the building panels 8, 9. There is no possibility of the formation of streaks due to depressions that impair the aesthetic appearance, and since the decorative lip 5 is in close contact with the end faces of the building panels 8 and 9, the sealing performance can be improved.

Claims (1)

[Scope of utility model registration request] The joint material used for the joints of construction panels has a generally rectangular cross section with multiple upward sealing lips protruding from both sides and a depression on the top surface, with a roughly T-shaped cross section in the center of the depression. When a decorative lip is protruded and the joint material is inserted into the concave groove for installing joint material on a construction panel, the joint body is compressed laterally by the end surface of the panel, and the uppermost lip of the multiple sealing lips is pushed upward. Push up the flange part of the raised decorative lip, and form the uppermost lip and flange part so that the flange part changes from an upwardly convex state to a horizontal state, closing the concave groove, and aligning with the outer wall surface of the building panel. A joint material for architectural panels that is characterized by:
