Description

[Detailed description of the invention] Technical field This invention relates to the technology of a joint device for wall panels of movable partitions (hereinafter referred to as panels), and in particular, joints for sealing (interval sealing) in clean rooms, etc. Related to filling technology.

BACKGROUND ART Conventionally, synthetic resin or metal joint materials have been used to fill the joints that occur when connecting panels to studs, but both are used primarily for the aesthetic purpose of preventing the joints from being exposed. It is something that is done. There are also joint connectors that combine joint filling and panel connection.

However, even with these common joint materials, the joint frames are not completely filled. That is, according to these, there is always a gap between the joint and the joint material.

For this reason, in clean rooms such as hospitals and factories, where it is necessary to prevent the adhesion of dust and to be able to thoroughly wash and clean the joints, filling or sealing agents such as putty or pasta are used to fill the joints. It is possible to completely seal the joint immediately, to apply a joint material that does not lose its shape after steaming into the joint frame, or to use it in combination with pasta or the like.

However, all of these methods are difficult to install (attachment work) and require a lot of time and labor.In addition, steel joint materials are very expensive, and on the other hand, with pasta or Para joint materials, dirt tends to adhere to them. Also, mold and the like can grow and stick to the room, making it a problematic place to use as a clean room.

The present invention is a creation of a joint device for use in such clean rooms, and has been made in order to eliminate the above-mentioned conventional drawbacks in joints in cleaning rooms.

DISCLOSURE OF THE INVENTION The present invention mixes an antifungal agent into a synthetic resin to prevent the attachment of mold, etc., and uses a combination of a hard material and a soft material with elasticity as the synthetic resin material. The joint body is formed of a hard material, and seal pieces made of a soft material are integrally provided on the left and right sides of the joint body in three stages, top, middle, and bottom, protruding outward at right angles to serve as a joint material, and are fitted into the joint material. A locking means is provided on the means and a metal receiving member that receives the same, and the joint material is fitted and attached to the receiving member fixed to a stud, etc., and the joint frame is completely closed with a seal piece on the joint material, and further This is a creation in which the middle and lower seal pieces complement the seal and make it stable.

BEST MODE FOR CARRYING OUT THE INVENTION In order to describe the present invention in more detail, the same will be explained below with reference to the accompanying drawings.

The joint device 1 of the present invention is composed of a joint material 2 and a support material 3, as shown in FIGS. 1 and 2.

The joint material 2 is made of synthetic resin mixed with an anti-mold agent (not shown), and the joint body 4 is made of a hard synthetic resin material, and the joint material 4 is made of a soft and elastic synthetic resin material. Seal piece 5, middle seal piece 6, and lower seal piece 7 are integrally formed.

The joint main body 4 is formed by opening both the open ends 1 of the side parts 9, 9 of a horizontally elongated member 8 having a U-shape with a downward opening in the longitudinal section.
0 and 10 are shaped downward into a quarter circular shape, and one half-chord part 11 is aligned with the line of the outer wall 12 of the side part 9, and the other half-chord part 11 is aligned with the line of the outer wall 12 of the side part 9. The protruding portions of the other half-chord portions 11 are cut diagonally downward to form insertion claws 14, 14.

The upper seal piece 5 is attached to the upper side of the U-shaped upper side part 15 and side part 9 of the downward opening in the longitudinal section of the joint main body 4, and converts the bottom part 16, which has a downwardly facing trapezoidal shape in the longitudinal section, into a rectangular shape. It is a horizontally elongated elastic complex having a rectangular shape with a shallow notch in the longitudinal direction equal to the size of the upper side 15 of the joint main body 4.

The middle seal pieces 6, 6 and the lower seal pieces 7, 7 are arranged in order below the upper seal piece 5 and above the upper seal piece 5.
is slightly shorter than the protrusion of the outer wall 12 of the side portion 9,
It is an elastic body in the form of a horizontally elongated plate with a thin round tip and projecting outward from 12 at a right angle.

The receiving material 3 is formed from the upper surface 18 of the U-shape in a horizontally elongated metal frame 17 that is made of metal and has a U-shape with a downward opening in the longitudinal section and is one size larger than the U-shape in which the joint main body 4 has a downward opening in the longitudinal section. Symmetrically with respect to the center line, column-shaped receiving projections 19, 19, which are small projections extending horizontally upward at right angles, and trapezoidal locking claws 20, 20, which are integrated with the upper ends of the receiving projections, are projected. It is. The locking pawl 20 has a trapezoidal longitudinal section, one end 22 of its lower side 21 is aligned with the inner end 23 of the receiving protrusion 19, and the other end 22 is aligned with the outer end 24 of the receiving protrusion 19. It is made to protrude outward from the top. Receiving protrusion 19,
The top surface 18 sandwiched between 19 and 2 is screwed into stud 2.
5, etc., and serves as a groove portion 26 for fixing the receiving member 3.

Now, as shown in FIG. 3, the receiving material 3 is attached to the joint frame 29 made up of the edge frames 28, 28 of the panels 27, 27 mounted on the stud 25, using the locking claws 20.
Attach and fix the joint with the upper seal piece 5 facing outward, press the joint material 2 toward the receiving material 3 with the upper seal piece 5 facing outward, and insert the insertion claws 14 of the joint body 4 into the locking claws 20 of the receiving material 3. , 20, and at the same time seal the joint frame 29 with the upper seal piece 5, the middle seal piece 6, and the lower seal piece 7.
to seal. The partition is as shown in Figure 4.

According to the joint device 1 of the present invention, as shown in FIG.
In particular, since the upper seal piece 5 has a longer protruding portion than the middle and lower seal pieces 6, 7, its elasticity allows it to bend outward along the side surface 30 as shown in the figure, forming a partial seal. In addition, the joint material 2 is the joint body 4
, the locking claws 20, 20 of the fixed receiving member 3
Snap the top, middle, and bottom seal pieces 5,
Together with the pressure contact with the joint frames 29 of 6 and 7, a strong and stable joint finish is achieved. In addition, the fitting connection between the joint material 2 and the receiving material 3 is performed using the insertion claw 1 of the joint material 2.
4, that is, the quarter part circular shape and the diagonal notch shape of the other half chord part 11, facilitate insertion, and the trapezoidal shape of the locking pawl 20 of the receiving member 3 facilitates insertion and locking. It is made strong.

In addition, regarding cleaning work in a clean room, it is possible to clean the smooth upper seal piece 5 mixed with an anti-mold agent with water or a cleaning solution, and remove mold from the middle and lower seal pieces 6 and 7 and the joint body 4. No occurrence was observed.

Note that the device 1 of the present invention can be manufactured at a unit cost less than one-tenth of the steel joint device, and is lightweight, making it easy to carry.

Industrial applicability The present invention can be used in clean rooms, which are in high demand these days.
It is known for its excellent cleaning effect and is often used for partitions other than clean rooms.
Its industrial applicability is extremely high.
