Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a joint structure for increasing the filtration area of a high-performance filter.

(Prior Art) Recently, demand for high performance filters (high collection efficiency filter papers) with large filtration areas, for example, exceeding 1 meter in length and width, has been increasing.
However, the length and width of the filter paper are standardized, so in order to expand the filter in the width direction, an intermediate frame is provided between the frames, and the filter is housed in each frame. When attaching the filter to a structure, etc., there were methods such as incorporating it through a beam or the like.

(Problem to be solved by the invention) However, the former integrated structure makes the filter large and inconvenient to handle and transport, and the latter requires a separate beam material etc. to be incorporated into a structure. However, since the filter is required, there were problems such as the troublesome work required to install the filter.

This invention was developed to solve the above problems, and it can be easily assembled on site to increase the size of the filter without increasing the size when manufacturing the filter. The purpose of this invention is to obtain a high-performance filter joint structure that eliminates the need for such components.

(Means for Solving the Problems) In the joint structure according to the present invention, the horizontal frame of a high-performance filter framed by a horizontal frame and a vertical frame is composed of a frame with a hollow cross section, and the vertical frame of the high-performance filter is connected. In this state, a connecting member is inserted into and penetrates the horizontal frames to connect them, and the outer ends of the joints of the vertical frames are sealed with a sealing material.

(Function) In the joining structure of the present invention, a plurality of high-performance filters can be connected by inserting and penetrating a connecting member into the connecting hollow horizontal frame in a state where the vertical frames of the high-performance filters are joined. After connecting the high-performance filter, sealing the outer ends of the joints of the vertical frames with a sealant can prevent air leakage from the frame joints.

(Example) An example of implementation of the present invention will be described in detail based on the drawings. Figures 1 and 2 are high performance filter F.
The filter paper 1 of the high-performance filter F is framed by the horizontal frame 2 and the vertical frame 3, and the filter paper 1 of the high-performance filter F is connected in the width direction.
The filter paper 1 used has standardized vertical and horizontal dimensions. Hollow section 2a of the horizontal frames 2, 2
, and vertical frames 3, 3 of two high-performance filters F.
In the state in which the horizontal frames 2, 2 are joined, a long connecting member 4 as shown in FIG. , the horizontal frames 2, 2 are connected. Note that the horizontal frames 2, 2 and the connecting member 4 may be fixed with screws.

Fig. 4 shows the joint portion of the vertical frames 3, 3 in the connected state of two high-performance filters F, and the outer end of the joint of the vertical frames 3, 3 has a V-shaped composite recess 5.
is formed, and a sealing material 6 is placed inside this composite recess 5.
is filled to seal the joint and prevent air leakage from the joint. Reference numeral 7 denotes a rib formed on the inner surface of the vertical frame 3 to reinforce it. Note that, as the above-mentioned sealing material 6, for example, a liquid curing sealer or a foam gasket is used.

To connect and assemble the above two high-performance filters F, first, with the vertical frames 3, 3 joined, the connecting member 4 is inserted into the hollow parts 2a, 2a of the upper and lower horizontal frames 2, 2 from the opening at one end. , connects the two high-performance filters F by penetrating them, and then fills the composite recess 5 at the outer end of the joint between the vertical frames 3, 3 with a sealing material 6 to increase the filtration area. The assembly of the high-performance filter is completed.

In addition, although the connection of two high-performance filters F is shown in the embodiment, it goes without saying that two or more high-performance filters F can be connected by the same coupling means as described above, if necessary. In this case, the length of the connecting member 4 corresponding to the three horizontal frames 2 may be used.

(Effects of the invention) As described above, according to the invention, the horizontal frame of the filter, which is framed by the horizontal frame and the vertical frame, is made of a hollow frame body, and when the vertical frames of the filter are connected, the horizontal frame The filters are connected by inserting and penetrating the connecting material, and the outer ends of the joints of the vertical frames are sealed with sealing material, so when manufacturing the filter, it is made as a single unit and can be easily assembled on site to increase its size. Therefore, the filter can be easily handled and transported, and there is no need to erect additional members such as beams to the structure when installing the filter. In addition, by sealing the sealant to the vertical frame joint,
Air leakage from vertical frame joints can be completely prevented. Furthermore, by inserting and connecting the connecting material into the horizontal frame of the hollow frame, a high-strength joint is possible, and even if external force is applied to the vertical frame, there is no reduction in the degree of sealing. There is.
