Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a large floor pan having a width of 3 meters and a length of 2 meters or more.

[Prior art]

Conventionally, large floor pans of this type are either integrally molded at a factory or otherwise connected together at a factory and then transported directly to the site.

However, in the case of large floor pans, there are many cases in which clumsiness occurs, such as bending and deforming during transportation or not being able to transport them through the frontage. Therefore, a conventional method has been used in which the floor pan is divided into two parts and each floor pan is connected with a shoelace member. However, since it is necessary to secure the necessary distance between the two floor pans for connection with the shoe rail member, positioning the two floor pans is troublesome. Since a member is used, the height of straddling when entering and exiting both floor pans becomes high, making it difficult to enter and exit the pans easily. To solve this problem, on one edge of the main floor pan,
A hook-shaped part bent from one edge of an additional floor pan (sub-floor pan) is engaged to connect both floor pans (JP-A-Sho).
59-10630) is available.

[The problem that the idea aims to solve]

By the way, if the edge of the main floor pan and the hook-shaped part of the additional floor pan (sub-floor pan) are directly fixed with fixing fittings (screws, bolts, etc.), the risk of water leakage etc. will increase, which is undesirable. In the prior art, both ends of the main floor pan and the additional floor pan (sub-floor pan) are fixed with fixing fittings, etc., and a support is provided protruding from the back side of the additional floor pan (sub-floor pan), and a Additional floor pans (sub-floor pans) on the floor of the building frame
By receiving this load, deformation stress is not applied to the portion that engages with the hook-shaped portion.

However, as a practical matter, there are undulations in the floor level of the building frame, so with the type that uses a support platform to receive pressure on the floor, it is impossible to avoid deformation stress acting on the hooked part, which prevents water leakage. I can't. Prepare several types of support stands of different heights,
It is possible to suggest that a support stand of a desired height corresponding to the space under the floor be selected and interposed at the construction site, or that the height of the support stand is adjustable, but maintenance and management of the support stand becomes troublesome, and the support stand When the height is adjusted, an upward deforming force is applied to the hook-shaped portion, which is not useful for avoiding water leakage.

The present invention has been made in view of the above-mentioned conventional circumstances, and its purpose is to improve the height of the floor pan in a large floor pan that engages the hook-shaped portion of the sub-floor pan with one edge of the main floor pan. To provide a large floor pan that does not apply deformation stress during adjustment to a hook-shaped part and is free from the risk of water leakage.

[Means to solve problems]

The technical measures taken to solve the above purpose are:
A main floor pan with legs, which has a horizontal surface for mounting on one edge of the other three edges, a horizontal surface for placing objects that is one step lower than the outer edge of the horizontal surface for mounting on the wall, and a rising surface for hooking; A sub-floor pan with legs, which is placed on the horizontal surface for placing objects and has a hook-shaped part on one edge corresponding to the rising surface for hooking and engaging with the rising surface for hooking. In the large floor pan configured with the above, a first connecting member having a horizontal surface on the upper surface and a vertical surface on the outer surface is provided on the back side of the main floor pan in a protruding manner toward the sub floor pan side; A second connecting member having a horizontal surface placed on a horizontal surface and a vertical surface in surface contact with the vertical surface is provided, and the horizontal surfaces and vertical surfaces of the first and second connecting members are fixed to each other with fixing metal fittings. This is the summary.

[Effect]

According to the above technical means, the hook-shaped portion of the sub-floor pan is engaged with the horizontal surface for loading and the rising surface for hooking of the main floor pan, and the horizontal surfaces of the first and second connecting members are engaged with each other, and the vertical surface of the first and second connecting members is engaged with each other. Secure them together with fixing metal fittings. Vertical tilting of the main floor pan and sub-floor pan is prevented by the surface bonding force created by clamping the fixing fittings between horizontal surfaces and vertical surfaces, and horizontal movement in the lateral direction is prevented by the fastening force of the fixing fittings. Therefore, the deformation stress generated when adjusting the height of the sub-floor pan by adjusting the legs is received by the first and second connecting material portions, and the hook-shaped portion and the main portion engaged with the hook-shaped portion are It does not act on one edge portion of the floor pan, and maintains the engaging portion in an initial watertight state.

[Effect of idea]

As described above, the present invention is a large floor pan of the type that connects the main floor pan and sub-floor pan through the engagement of hook-shaped parts. The above-mentioned engaging part (The engaging part between the hook-shaped part of the sub-floor pan and the edge of the main floor pan) Water leakage can be reliably prevented without causing damage to the caulking material or creating a leakage space between the hooked portion and the hook-shaped portion. Of course, even during long-term use, it has a stable leak-proof structure and promises improved reliability.
