Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a joining device for the lower part of a panel used in the construction of a space such as a clean room that requires high cleanliness and airtightness.

(Prior art) Fig. 3 shows a conventional joining device of this type, in which a panel guide (c) is supported via a screw rod (b) on a floor rail (a) fixed to the floor, and the panel guide (c) Supports the skirting board (d) fitted to the floor rail (a) above, and has a convex part at the top of the baseboard (d) and a recessed part in the bottom frame of the wall panel (e). It is constructed by fitting.

(Problems to be solved by the invention) In the conventional system, the floor rail (a), baseboard
(c), the bottom frame of wall panel (e) is made of thin steel, so its strength
It has problems with rigidity and poor accuracy when assembling panels.

Additionally, it has poor airtightness as a whole and cannot be used in spaces that require a high degree of cleanliness and airtightness, such as clean rooms.

(Means for solving the problem) The present invention was proposed in order to solve the above problem.It is fitted into an integrally molded groove-shaped foundation liner fixed to the floor so that its height can be adjusted freely. A lower frame is fitted into the integrally molded gate-shaped level adjustment plate, which is made up of a pair of left and right vertical pieces and an intermediate horizontal piece having a protrusion in the center that connects the middle parts of the two vertical pieces. both the vertical pieces are erected on the floor, the intermediate horizontal piece is fixed to the upper surface of the top piece of the level adjustment plate, and a concave strip is integrally formed on the lower surface between the two vertical pieces. Fitting the lower end of the molded wall panel and fitting the groove into the protrusion of the intermediate horizontal piece of the lower frame,
The present invention relates to a joining device for a lower panel, characterized in that an airtight gasket is crimped between both sides of the concave strip on the lower bottom of the wall panel and both sides of the protrusion on the intermediate horizontal piece of the lower frame.

(Function) Since the present invention is constructed as described above,
After adjusting the height of the gate-shaped level adjustment plate fitted to the groove-shaped foundation liner fixed to the floor, the lower frame is fitted to the same plate, and the vertical pieces on both sides of the frame are attached to the floor. erected on top,
In addition, an intermediate horizontal piece connecting the intermediate parts of each vertical piece is seated on the upper surface of the top piece of the gate-shaped level adjustment plate and fixed to the top piece, and the lower frame is held in a predetermined position with respect to the floor. Install.

In this state, the lower bottom of the wall panel is fitted into the recess formed between the left and right vertical pieces and the intermediate horizontal piece in the lower frame, and the groove formed in the lower bottom is inserted into the intermediate horizontal piece in the lower frame. The wall panel is attached to the floor by fitting into the protrusions of the wall panel, and at this time, due to the weight of the wall panel, the protrusions on both sides of the concave strip at the lower base and the intermediate horizontal piece of the lower frame are An airtight gasket is crimped between both sides of the wall frame to maintain the airtightness of the mounting portion of the wall frame to the floor.

(Effects of the invention) As described above, according to the invention, the wall panel can be easily attached to the floor, and at this time, the foundation liner regulates the attachment position of the wall panel and the lower frame to the floor, The lower frame is fixed to the foundation liner via a level adjustment plate that is fitted in such a way that the height can be adjusted. Since the concave strip molded on the bottom is fitted into the protruding strip of the intermediate horizontal piece of the lower frame, the wall panel is positioned in the wall thickness direction, and thus the wall panel is accurately installed in a predetermined position. .

Since the base liner, level adjustment plate, lower frame, and lower bottom of the wall panel are each integrally molded, they have sufficient strength and rigidity and will not be displaced or deformed during installation or work of the wall panel. construction accuracy is improved.

Further, according to the present invention, an airtight gasket is pressed between the wall panel and the lower frame at the same time as the wall panel is installed, thereby maintaining the airtightness of the floor attachment portion of the wall panel.

(Example) The present invention will be described below with reference to the illustrated embodiments.

A is a groove-shaped foundation liner made of extrusion molded aluminum or the like, and is fixed to the floor B via mounting bolts 1.

A level adjustment bolt 2 with a nut 11 is installed on the bottom piece of the basic liner A, and a top piece 3 of a gate-shaped level adjustment plate C made of extrusion molded aluminum or the like is inserted into the bolt 2, and Both side pieces 4 are slidably fitted to both side pieces 5 of the base liner A.

D is a lower frame made of extrusion molded aluminum or the like, and is located between a pair of left and right vertical pieces 6, 6, and has an intermediate horizontal piece 8 with a gate-shaped protrusion 7 molded in the center.
are integrally connected.

Reference numeral E designates a wall panel, in which a grooved portion 10 is molded at the center of the lower bottom of a bottom frame 9 made of integrally molded aluminum or the like.

Then, the level adjustment plate C is set at a predetermined height by operating the nut 11 screwed onto the level adjustment bolt 2 installed in the foundation liner A, and each side piece of the plate C and the foundation liner A is set to a predetermined height. After fixing 4 and 5 with screws 12, fit the lower recess formed between the lower surface of the intermediate horizontal piece 8 of the vertical pieces 6 and 6 on both sides of the lower frame D onto the bolt 2 protruding onto the plate C. , an intermediate horizontal piece 8 is seated on the top piece 3 of said plate C;
The lower frame D is supported on top, and the lower frame D is fixed by tightening the mounting holes 8a and 3a provided in the two pieces 8 and 3 with screws 13.

Next, airtight gaskets F are attached to the upper surfaces of both sides of the protrusion 7 on the top piece 8 of the lower frame D, and the upper surface formed between the vertical pieces 6 on both sides of the lower frame D and the upper surface of the intermediate horizontal piece 8 is attached. The lower bottom part of the wall panel E is fitted into the recess, and the recessed part 10 is fitted onto the protrusion 7 of the intermediate horizontal piece 8 in the lower frame D to attach the wall panel E, and both sides of the recessed part 10 are fitted. An airtight frame F is crimped between the lower surface of the bottom frame 9 and both sides of the protruding portion 7 of the intermediate horizontal piece 8 by the weight of the wall panel E, and the attachment portion of the wall panel E to the floor is airtightly bonded. This is to ensure that

According to the embodiment described above, the wall panel E can be easily attached to the floor B, the height position of the wall panel E is adjusted by the level adjustment plate C, and the bottom frame 9 of the wall panel E is adjusted. The positioning of the wall panel E in the wall thickness direction is achieved by fitting the concave portion 10 provided in the plate C into the protruding portion 7 of the intermediate horizontal piece 8 in the lower frame D supported by the plate C. The wall panel E is then mounted precisely in place.

Furthermore, when installing the wall panel E, an airtight gasket F is pressed between the bottom frame 9 of the panel E and the intermediate horizontal piece 8 of the lower panel D, and at the same time the wall panel E is installed, the floor part of the panel E is The airtightness of the mounting area is maintained.

Furthermore, the foundation liner A, the level adjustment plate C, the lower frame D, and the bottom frame 9 of the wall panel E are all integrally molded and have sufficient strength and rigidity, so that there is no risk of displacement or deformation when the wall panel E is installed. There is no leakage, construction accuracy is improved, and the airtightness of the floor attachment portion of the wall panel E is further improved.
