Description

[Detailed Description of the Invention] This invention relates to a surface lattice unit that can be attached to windows in kitchens, washrooms, toilets, etc.

Currently, most grids are made of aluminum, which has excellent strength and corrosion resistance. By the way, conventional aluminum face lattices are made by cutting extruded lattice sections and side beam sections to predetermined dimensions, and forming screw holes at predetermined positions to form a lattice and side lattices. It is assembled by connecting the beams with a plurality of screws that screw into screw holes. but,
In this type of surface grid, the grid spacing and the crossbar spacing are determined at the time of forming the screw holes, so it cannot follow the size of the mounting window and is not flexible. Furthermore, since the step of forming screw holes is added to the production of the lattice and cross-pieces, the manufacturing process of the lattice and cross-pieces is lengthened, and extra manpower is required, which increases manufacturing costs.

This invention was devised in order to solve the above-mentioned conventional problems, and its purpose is to form a lattice and a crossbeam with continuous grooves in the longitudinal direction, and to attach metal fittings to connect these grooves. By screwing them together, you can freely decide the installation interval of the grid and crossbars during assembly to follow the size of the installation window, and shorten the manufacturing process by omitting the step of forming screw holes. It is an object of the present invention to provide a surface lattice unit which can be made more compact and has a lower manufacturing cost.

This invention will be explained below with reference to an illustrative embodiment.

In the figure, numeral 1 is a surface lattice unit, numerals 2 and 2 are upper and lower horizontal beams, numerals 3, . . . are lattices, numeral 4 is a connecting fitting, and numeral 5 is a bracket.

The upper and lower cross-pieces 2, 2 are formed to have a substantially rectangular cross section, and lip grooves 6, 6 are formed on the four sides of the upper and lower cross-pieces 2, 2 to extend in the longitudinal direction of the upper and lower cross-pieces 2, 2, respectively.
In addition, the upper and lower horizontal beams 2, 2 are made of a mixture of cement or mortar mixed with steel fiber, carbon fiber, asbestos fiber, carbon fiber, etc., and the orientation of the steel fiber, carbon fiber, and carbon fiber is enhanced, and the cement or mortar is used as a material. It is molded using an extrusion molding method to increase adhesion and strength. In addition, the upper and lower crosspieces 2, 2 are considered to be somewhat heavy due to the material they are made of, and in order to eliminate this, they are molded with a plurality of communication holes 7, 7 that communicate with each other in the longitudinal direction of the upper and lower crosspieces 2, 2, making them lightweight. is being transformed.

The gratings 3, . . . are formed into a cylindrical shape with a substantially trapezoidal cross section, and lip grooves 6, . Furthermore, the lattice 3, .

The connecting fitting 4 consists of an angle member 8 and fixing screws 9, 9. The angle member 8 is disposed between the horizontal struts 2, 2 and the lattice 3, .

The fixing screws 9, 9 pass through through holes formed in the portions of the angle material 8 corresponding to the lip grooves 6, 6, and are arranged within the lip grooves 6, 6 in correspondence with the angle material 8. It is screwed into the screw hole of the pads 10, 10. Then, by firmly tightening the fixing screws 9, 9 with the angle material 8 and the butts 10, 10 so as to sandwich the lips 6a, 6a of the lip groove section 6.6, the side legs 2, 2 and the lattice 3 ,... are connected.

In such a configuration, when assembling the surface lattice unit 1, the fixing screws 9, 9 of the connecting fittings 4 are loosely tightened to the extent that the connecting fittings 4 slide on the lip grooves 6.6, and the side beams 2, 2 and the lattice 3 are assembled. , ... are temporarily connected. Then, Yokogi 2, 2 and lattice 3,...
... together with the connecting fittings 4, determine the installation interval, and firmly tighten the fixing screws 9, 9.

The thus constructed panel lattice unit 1 is attached to the periphery of the window by means of brackets 5,5. The fixing screws 9, 9 fixing the surface lattice unit 1 to the brackets 5, 5 are attached to pads 10 arranged in the lower lip grooves 6 of the upper and lower horizontal legs 2, 2 corresponding to the brackets 5, 5. , 10 screw holes,
Attach the fixing screws 9, 9 to the brackets 5, 5 and the pad 1.
The surface lattice unit 1 is attached to the brackets 5, 5 by firmly tightening the lips 6a, 6a of the lip groove portion 6 so as to sandwich the lips 6a, 6a of the lip groove portion 6.

To attach the screen lattice unit 1 around the window, first attach the brackets 5, 5, and then attach the screen lattice unit 1 to these brackets.

In the embodiment, the fixing screws 9, 9 are screwed into the screw holes of the pads 10, 10 arranged in the lip groove 6, but they may be screwed directly into the lip groove 6. .

This invention has the above configuration and can be expected to have the following effects.

The lattice and the lattice are molded with continuous grooves in the longitudinal direction, and are connected to each other by screwing connecting fittings to the grooves, so when assembling the lattice and the lattice, the installation interval can be adjusted. It is highly flexible as it allows you to freely decide on the size of the window to be installed. Furthermore, since the step of forming screw holes is omitted when forming the crosspieces and the lattice, the manufacturing process can be shortened and the manufacturing cost can be reduced.

In addition, the upper and lower cross-sections and the lattice are all formed into hollow cross-sections by extrusion molding from a mixture of cement and mortar mixed with reinforcing fibers such as steel fibers, making them lightweight even though they are concrete products. Moreover, the strength can be improved. In addition, the material is highly durable with no fear of rust, and there is no fear of it being easily broken, making it extremely effective in preventing crime.

Furthermore, it can be said that the material gives a solid feel and the design effect is extremely high.
