Description

Prevent to strike and destroy and be convenient for construction maintenance's elevator mouth threshold stone structure

Technical Field

The utility model relates to a building decoration technical field especially relates to an elevator mouth threshold stone structure that prevents to strike destruction and be convenient for construction and maintain.

Background

The traditional elevator entrance threshold stone structure is a three-layer structure which is formed by sequentially arranging a leveling layer, a threshold stone paving cement mortar bonding layer and a threshold stone from an indoor unfinished ground elevation, wherein the threshold stone paving cement mortar bonding layer is a rigid support layer of the threshold stone. Under traditional threshold stone structure condition, common main construction flow is: firstly, performing main leveling layer construction; secondly, placing the threshold stone coated with cement mortar at the bottom at a preset installation position, and enabling the surface of the threshold stone to be horizontal and the top elevation of the threshold stone to be consistent with the top elevation of the elevator door sill in a manual pressing or rubber hammer knocking mode; and thirdly, jointing and cleaning after the cement mortar bonding layer is hardened.

The doorsill stone constructed in the traditional structure form has the following defects in later use and maintenance: first, in the operation phase, the probability of the cracking of the threshold stone after being impacted by external force is increased, and the later maintenance cost is increased. Due to the groove structure of the elevator sill, when the trolley carrying furniture, building materials and goods is pushed out of the elevator, the trolley must be bounced at the sill, and then huge instantaneous impact force is generated on the edge of the threshold stone when the trolley falls to the ground on the threshold stone. If the height difference exists between the threshold stone and the elevator sill, when any one condition of local hollowing, incomplete mortar filling, untight combination of mortar and the threshold stone exists at the edge of the threshold stone, the elevator sill stone is easy to crack or break. If the threshold stone is not replaced, a penetrating crack develops from a crack at the edge of the threshold stone to a crack, so that the building attractiveness is seriously influenced; if the threshold stone is replaced, the maintenance cost is increased.

Secondly, during maintenance, the sill stone is inconvenient to maintain and operate. When the existing threshold stone structure is adopted, electric and pneumatic breaking and dismantling equipment or manual chiseling and removing are needed to be used for replacement. In the dismantling process, the damaged threshold stone is within 2mm from the elevator door, the elevator sill, the elevator exit door pocket and the adjacent floor tiles, the operation space is limited, the mechanical operation is likely to damage peripheral materials, the loss is further enlarged, and the dismantling difficulty is high. Meanwhile, when the new threshold stone with the bottom coated with cement mortar is installed back into the original groove again, the gap between the original groove and the periphery is usually only 1-2 mm, the installation space is not enough, the process time for fixing the new threshold stone in the original installation groove is long by repeatedly adjusting the position of the threshold stone, the cement mortar has fluidity, the bottom mortar of the threshold stone can continuously fall off in the installation process, the bottom mortar of the threshold stone is not filled enough, the lower edge part of the threshold stone which is paved again can not be filled with the mortar, and the threshold stone is empty and bloated, or the threshold stone is not tightly bonded, and hidden danger is buried due to the fact that the threshold stone is damaged again after being impacted by a trolley for transporting heavy objects.

Third, maintenance can be performed for a long time with adverse effects on the building facilities, adjacent elevator facilities, and normal use of the building. When in maintenance, the original broken threshold stone and the lower bonding layer are chiseled for a longer time; meanwhile, the process time of completely hardening the bonding mortar at the lower part is longer after the threshold stone is paved, so that the corresponding elevator needs to be stopped for a long time, and the influence time on the normal use of the elevator and the building is longer.
