How to make a hatch in the basement

The process of manufacturing a basement hatch is divided into several stages: the choice of material, thinking out the design, acquiring the missing parts and the implementation of the project.

When developing a homemade hatch in a basement, highlights are taken into account:

Convenient location of the Laza in the underground;
Minimum sizes of internal opening 750x750 mm;
Combination in the design of moderate weight and sufficient strength;
Tightness and thermal insulation of the area covered;
The placement of the upper plane of the hatch flush with the floor;
Attractive outdoor finish.

Additionally, the design can be equipped with a function of smooth closure / opening and a fixing device.

Luke B. wooden floor It is logical to make a thickness of 30-50 mm thick and plywood sheet. The sawn timber is cut in size, planes and impregnated to the assembly of the olphoi or antiseptic.

The procedure for making wood lid:

The support frame is constructed, attached to the draft floor;
The floorboards are cut in size, leaving the gap of 4-5 mm around the perimeter of the lid;
Billets are connected by transverse bars;
Longitudinal rails are nailed along the edges of the shield;
Mineral wool laid inside the crates;
The insulation is closed with a plywood sheet;
The top of the hatch is separated by the material from which the floor is made indoors;
The cover is installed on the loop, the handle is screwed.

For the manufacture of a base metal from metal will require tools:

Bulgarian, cutting circles;
Welding apparatus, electrodes;
Drill, drill.

Necessary materials:

Steel sheet thickness 3-4 and 0.5-1 mm;
Corner with a side of 40-50 mm;
Styrofoam;
Rubber compactor;
Self-tapping screw;
Primer.

Work begins with Laza and drawing drainage.

Billets are cut by a grinder on their own if there is a suitable material in the farm. Otherwise, the metal bases are ordered according to certain sizes. Steel sheet should block the dimensions of the lazium slightly, the corners are placed at a distance of 5-10 mm from the edge. 1-2 ribs are added in the middle. Sliced \u200b\u200bblanks are welded without skips, the assembled cover is determined from rust and ground. The inner cells are laid foam, which hides under a thin sheet of iron. The finished hatch is mounted using anchors, after which the seal is glued.

Make a swimming hatch of a smooth move and fixing in the open position in two ways:

Using spring loops from the car hood - a suitable option for a wooden and light metal cover;
Using gas shock absorbers - produced different power for hatches of any mass and sizes.

The closer parameters are calculated based on the weight of the structure, and the attachment points are placed so that the fully unloaded shock absorber opened the cover at 90 °.

The knob on the lid is performed secret or folding. Specific devices for sale, having an in-depth bowl and embedded in the hatch plane. Another option is a removable handle that allows you to prevent the random opening of the hatch by children.
