Description

Elevator mouth threshold stone structure convenient to change construction

Technical Field

The utility model relates to a building decoration technical field, concretely relates to elevator mouth threshold stone structure convenient to change construction.

Background

The method for decorating by arranging the doorsill stones between the elevator sill and the tile paving area in the building is a common decoration method in the building decoration engineering, and has two functions: 1. filling pits between the elevator door sill and the tile paving area in the building; 2. decorate the building interior together with elevator mouth door pocket, skirting line. The decoration mode for arranging the threshold stone is almost the current practice in the building decoration industry at the present stage.

Traditional elevator mouth threshold stone structure begins to set gradually main screed-coat, threshold stone and spreads and paste cement mortar tie coat, threshold stone from the interior unfinished ground elevation of room, totally three layer construction. 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 in a manual pressing or rubber hammer knocking mode, wherein the top elevation of the threshold stone is consistent with the top elevation of the elevator door sill; and thirdly, jointing and cleaning after the cement mortar bonding layer is hardened. The threshold stone constructed by the structure is broken by the impact of a heavy object, and is inconvenient to construct when needing to be replaced.

The doorsill stone constructed in the traditional structure form has the following defects in later use and maintenance: first, in the replacement process, the construction operation is inconvenient. 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 a new threshold stone coated with cement mortar at the bottom is installed back into the original groove again, the gap between the original groove and the periphery is extremely small and is only 1-2mm, the installation space is not enough, the process time for fixing the threshold stone in the original installation groove is long when the position of the threshold stone is adjusted repeatedly, and due to the fluidity of the cement mortar, the mortar at the bottom of the threshold stone can continuously fall off in the installation process, so that a floor tile area, an elevator car and the like can be stained, and the construction operation is inconvenient.

Second, maintenance can be carried out 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 time of the process of waiting for the lower bonding mortar to be completely hardened after the threshold stone is paved is long, so that the corresponding elevator needs to be stopped for a long time, and the influence on the normal use of the elevator and the building is long.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an elevator mouth threshold stone structure convenient to change construction, the utility model discloses lay traditional threshold stone and paste cement mortar tie coat and change into the supporting layer with adjustable the sand is joined in marriage to the grade, simplified the construction flow, shorten construction and maintenance time greatly, it is long to the use interference of elevator facility to have reduced the maintenance construction, solve because of the limited threshold stone of messenger's operating space change construction difficulty, change the cost of labor higher, use the influence great and lead to the problem of maintaining the difficulty to elevator mouth threshold stone to corresponding building facilities such as elevator.
