The floor is undoubtedly one of the most important elements of warehouse facilities. Its damage is a serious problem for both the user and the building manager. It is the cause of constant frustration and irritation of users, especially forklift operators and the owners themselves.
The critical point of every floor are, of course, expansion joints that cannot be eliminated.
The wheels of vehicles that pass through a straight, open expansion joint (even filled with joint filling sealant) fall into it with impetus, at the same time hitting the edge of the concrete slab or the steel profile, if expansion joints were installed when making the floor.
After a certain period of operation, cracks and crumbling of the expansion joints begin to appear. The time of the first damage depends on the width of the gap, the intensity of the passage of vehicles, the hardness and size of their wheels and their weight and speed. If the edge was reinforced, damage occurs just behind the steel profile used.
An irreversible destruction process begins, which cannot be stopped. At first, the concrete is destroyed only along the profile, with time the larger surface is devastated. Steel expansion joints with a thickness of 2 × 5 mm or 2 × 10 mm or even a profile with a width of over 100 mm used to reinforce the edges of slabs when making the floor does not guarantee that this phenomenon will be eliminated. Simple boundary steel profile - concrete always leads to concrete cracks. Such damage becomes wider and deeper with time. When a problem with expansion joints occurs, an irreversible sequence of deepening damage begins. These, however, grow at an alarming rate, become larger, larger and larger ... this process can no longer be stopped. Don't let this happen to you either!
Growing damage leads with time to the inability to use the floor and thus part or the whole hall! The floor made at low cost quickly becomes expensive to use. These costs are influenced by, among others destructive truck wheels that require constant replacement and damaged loading and unloading equipment. Damaged goods that fall from trembling carts passing through damaged expansion joints also have their share in them. Be careful! SAVINGS AT THE BEGINNING OF INVESTMENT ARE VERY EXPENSIVE!
This closed circle can only be stopped by permanent repair, which ELIMINATES THE CAUSE OF DAMAGE!
HC-SINUS SLIDE REPAIR®
This repair system ensures the passage between concrete slabs 100% free of shocks and even the slightest vibrations, so the appearance of any damage in the future is simply impossible! They provide continuous support for the wheels when passing through expansion joints. As a result, the wheels seem to slide from one plate to another without any impact, vibration or shock. This feature is characterized by sinusoidal expansion joints that arise in modern Sinus Slide® technology. If COSINUS SLIDE® or HC-Delta SINUS Slide® profiles were used initially, no repair would be necessary.
The structure consists of two sinusoidal steel profiles with a thickness of 5 mm, between which there is polyethylene foam. The flexible material allows compensation of shrinkage and expansion movements. The foam is 20mm higher than steel profiles and protrudes downwards beyond their end, which ensures separation of repair material also under the profiles. The profiles are equipped with anchoring elements, they are flat steel profiles parallel to the filling level and a stirrup formed in the letter U from wire. Flat steel profiles facilitate assembly. At their ends there are holes through which rods can be inserted, which are stuck into the ground and which can be welded to them.
AVAILABLE PROFILE HEIGHT:
A = 35mm; 50mm; 60mm; ; 80mm.
Performing the repair is very simple. Cut with a saw and remove damaged concrete on both sides of the expansion joint to the appropriate width and depth - depending on the extent of the damage and the situation. Along the exposed expansion joint, you can lay the backer rods by pushing it slightly into the joint.
Optionally, mounting aid consist of a 500mm long L-profile 40 x 40 mm including 2 fixing screws are supplied with the repair profiles. The HC-Sinus Slide® Repair profile should be hung on special hooks of mounting L-profile. By adjusting the hooks with wing nuts, it can be leveled accordingly. Drill holes in the ground and place the rods in them so that they pass through the holes in the tiles. Weld the bars to the tiles and cut them just abowe tiles. Then removing the mounting brackets, fill the hole by repair mortar and then finish the floor by seizing and polishing.
