Abstract

The utility model discloses an assembled elevator pit, which comprises four corresponding upright posts, a plurality of precast concrete blocks and precast slabs, wherein the upright posts are vertically arranged; the cross section of the upright post is rectangular, one corner of the upright post is an arc corner, and two straight sides of the upright post are provided with rectangular grooves; the precast concrete block is a rectangular concrete block, and two ends of the precast concrete block are provided with rectangular clamping blocks corresponding to the rectangular grooves; a plurality of fasteners are uniformly arranged on the prefabricated plate. According to the utility model, four upright posts are firstly installed at the reserved positions installed in the elevator pit, then a plurality of precast concrete blocks are installed among the upright posts one by one, and finally the precast slabs are installed and reinforced through the fasteners, and the precast concrete blocks are adopted for the current installation and construction, so that the current concrete pouring is not required for the construction, the construction period is greatly reduced, and the construction period can be reduced by 70-80%. In addition, the upright post and the precast concrete block are connected through the clamping groove and the clamping block, so that the mounting is convenient, the structural stability and the combination firmness are very high, and the safety is good.

Description

Assembled elevator pit

Technical Field

The utility model relates to an elevator device, in particular to an assembled elevator pit.

Background

As the aging society progresses further, the aging population becomes more and more. The old people mostly live in old districts, but the multi-storey houses in the old districts are not provided with elevators, so that the old people face the increasingly serious problem of difficulty in going upstairs and downstairs. Therefore, the state goes out of the old building and installs the elevator.

However, in the existing additionally-installed elevator pit, a pit is dug on the ground of a preset place, then reinforcing steel bars are laid, and then concrete is poured, so that a large amount of concrete needs a long time to solidify, and is easily influenced by weather, so that great inconvenience and high labor intensity are brought to site construction.

Therefore, the existing elevator-added concrete pouring pit has the problems of long construction time and high labor intensity.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a fabricated elevator pit. The utility model has the advantages of relatively shorter construction time and relatively lower labor intensity.

The technical scheme of the utility model is as follows: an assembled elevator pit comprises four corresponding upright posts which are vertically arranged, a plurality of precast concrete blocks which are horizontally arranged between the adjacent upright posts and precast slabs which are arranged at the top of each upright post and connected with the precast concrete blocks; the cross section of the upright post is rectangular, one corner of the upright post is an arc angle, and two sides corresponding to the arc angle are provided with rectangular grooves; the precast concrete block is a rectangular concrete block, and rectangular clamping blocks corresponding to the rectangular grooves of the stand columns are arranged at two ends of the precast concrete block; and a plurality of fasteners are uniformly arranged on the prefabricated plate.

In the fabricated elevator pit, the width of the precast concrete block corresponds to the width of the upright column, and the length and the thickness of the precast concrete block are set according to actual requirements.

In the fabricated elevator pit, the prefabricated slab is uniformly provided with a plurality of fastening holes, and the fastening blocks correspond to the upright posts and the prefabricated concrete blocks respectively.

Compared with the prior art, the utility model firstly installs four upright posts at the reserved positions installed in the elevator pit, then installs a plurality of precast concrete blocks between the upright posts one by one, finally installs the precast slabs and carries out reinforcement through the fasteners, and the precast concrete blocks are installed and constructed at present without carrying out concrete pouring at the present time of construction, thereby greatly reducing the construction period and reducing the construction period by 70 to 80 percent. In addition, the upright post and the precast concrete block are connected through the clamping groove and the clamping block, so that the mounting is convenient, the structural stability and the combination firmness are very high, and the safety is good.

Therefore, the utility model has the advantages of relatively shorter construction time and relatively lower labor intensity.

Furthermore, one corner of the upright post is set to be an arc angle, so that the degree of injury caused by spraying of pedestrians, vehicles and the like is reduced, and the safety is further enhanced.

Detailed Description

The utility model is further illustrated by the following figures and examples, which are not to be construed as limiting the utility model.

Examples are given. An assembled elevator pit is formed as shown in figures 1-5 and comprises four corresponding upright posts 1 which are vertically arranged, a plurality of precast concrete blocks 2 which are horizontally arranged between the adjacent upright posts 1 and precast slabs 3 which are arranged at the top of each upright post 1 and connected with the precast concrete blocks 2; the cross section of the upright post 1 is rectangular, one corner of the upright post is an arc angle 11, and two sides corresponding to the arc angle 11 are provided with rectangular grooves 12; the precast concrete block 2 is a rectangular concrete block, and two ends of the precast concrete block are provided with rectangular fixture blocks 21 corresponding to the rectangular grooves 12 of the upright posts 1; and a plurality of fastening pieces 4 are uniformly arranged on the precast slab 3.

The width of the precast concrete block 2 corresponds to the width of the column 1.

The precast slab 3 is uniformly provided with a plurality of fastening holes 31, and the fastening blocks 31 correspond to the upright posts 1 and the precast concrete blocks 2 respectively.

The working principle is as follows: as shown in fig. 1-5, firstly, four upright posts 1 are vertically installed at the construction reserved position, then the precast concrete block 2 is installed between the connected upright posts 1, and the rectangular fixture block 21 on the precast concrete block 2 is correspondingly clamped with the rectangular groove 12 on the upright post 1.

Finally, the prefabricated panels 3 are installed on top of the columns 1 and the installation is completed by installing the fastening members 4 into the fastening holes 31 of the prefabricated panels 3.
