Threshold device with shrinkage protection assistance for building construction

Abstract

The invention discloses a threshold device with shrinkage protection assistance for building construction. The structure of the threshold device with the shrinkage protection for the building construction comprises a door frame and a threshold device body, the threshold device body is arranged on the inside of the door frame and the door frame is attached to the outer surface of the threshold device body, and the threshold device body is embedded on the ground. The threshold device body comprises a main body, a moving threshold block, a holding handle and a fixed threshold block. The thresholddevice with shrinkage protection assistance for building construction has the beneficial effect that under the effect of matching of a roller and a guide slide rail, the two sides of a threshold canshrink towards the middle, a trolley is conveniently pushed into a door, the trolley is prevented from pressing the threshold, and the threshold being pressed to deformation or damage is effectively avoided; under the effect of a guiding booster and an electromagnetic device, the push resistance of the trolley can be effectively reduced, the driving power is improved, and the power to assist is provided; and a dust removal brush can clean dirt attached to the outer surface of the guiding booster, and the guiding booster is prevented from being stuck during rotating.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a threshold device for shrinkage protection and boosting for building construction. Background technique [0002] The threshold is generally set under the door frame. After the installation of the threshold is completed, when the construction personnel need to transport relatively heavy decoration materials during the later construction of the house, due to the relatively large amount of materials to be transported, trolleys are usually used. To transport materials, when transporting to the threshold, because the threshold is relatively high, it is difficult to push the trolley into the house, resulting in the need for manual handling many times, which greatly reduces the efficiency of decoration, and in the process of transportation, it is inevitable that it will hit The threshold is easy to be damaged or deformed by hitting the threshold. Since the threshold is generally in...

Problems solved by technology

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a threshold device for shrinkage protection and boosting for building construction, so as to solve the problem that construction personnel still need to transport relatively heavy decoration materials during the later construction of the house. When transporting a large amount of materials, trolleys are usually used to transport materials. When transporting to the threshold, due to the relatively high threshold, it is difficult to push the trolley into the house, resulting in the need for manual handling many times, which greatly reduces the decoration cost. Efficiency, and in the process of transportation, it is inevitable to bump into the threshold, which is easy to damage or deform the threshold. Since the threshold is generally installed in a fixed way, it is relatively troublesome to disassemble, and when pushing the trolley, due to the relatively heavy material, When pushing through the threshold, its resistance will be relatively high, and it will be relatively laborious to push
