Abstract

A prefabricated concrete-frame elevator shaft enclosed by plastic-steel plates comprises an underground part having a cast-in-situ concrete structure and an overground part having a prefabricated concrete-frame structure with plastic-steel plate enclosure. Generally, a cast-in-situ concrete elevator shaft may have a height of 1m above the ground. The elevator shaft of the overground part comprises four concrete columns and concrete beams, and has a prefabricated concrete-frame which is enclosed by plastic-steel plates. The elevator shaft is fabricated in a prefabrication factory and transported to the construction site, and the bottom portion of the elevator shaft is connected with the cast-in-situ concrete elevator shaft walls to form an integration. The beneficial effects of the utility model are that, the on-site installation operations are reduced, the construction progress is significantly accelerated, the cost is lowered, the wet operations are reduced, the construction waste is reduced, the energy is saved, the environment is protected, the productivity is raised and the installation is facilitated.

Description

A kind of precast concrete framework plastic-steel plate is gone along with sb. to guard him elevator shaft

Technical field

The utility model relates to the building structure technology field, is that a kind of precast concrete framework plastic-steel plate is gone along with sb. to guard him elevator shaft.

Background technology

At present, in housing construction, adopt the cast-in-situ concrete elevator shaft mostly, though its globality is better; But it is a wet trade, the reinforcing bar materials are many, cost is high, long in time limit, especially for the dwelling house of needs repackings elevator, need a kind ofly not only shorten the construction period; And reduce cost, and effectively reduce wet trade, reduce building waste; Energy-conserving and environment-protective reduce manual work, the elevator shaft that increases productivity.

The utility model content

The utility model provides a kind of precast concrete framework plastic-steel plate to go along with sb. to guard him elevator shaft, reduces the on-site consolidation operation, accelerating construction progress greatly, and reduce cost; And effectively reduce wet trade, reduce building waste, energy-conserving and environment-protective; Reduce manual work, increase productivity, easy for installation.

For realizing above-mentioned purpose, the utility model is taked following technical scheme:

A kind of precast concrete framework plastic-steel plate is gone along with sb. to guard him elevator shaft; It comprises under ground portion and overground part; This under ground portion adopts cast-in-place concrete structure, and overground part is a precast concrete framework plastic-steel plate space enclosing structure, and under ground portion is about cast-in-situ concrete elevator shaft 1m above ground level; The precast concrete framework plastic-steel plate of overground part is gone along with sb. to guard him elevator shaft, includes four concrete columns and concrete beam, is a kind of precast concrete framework, and with the plastic-steel plate as the elevator shaft framework of going along with sb. to guard him; The bottom and the cast-in-situ concrete elevator shaft wall of this precast concrete framework plastic-steel plate elevator shaft link into an integrated entity, and are embedded with connecting reinforcement at a side external surface of concrete beam.

The precast concrete frame height designs by floor height, is provided with the slotted hole slot at the pillar top, is provided with latch in the pillar bottom, and latch inserts in the slotted hole slot at following one deck frame column top, and seals with high-strength non-shrinkage cement mortar.

Described precast concrete column is pre-buried expansion bolt will connect steel disc and be fixed on the concrete column outside through expansion bolt, be welded with angle steel connecting on the steel disc, and the upper and lower end of said plastic-steel plate is connected with angle steel through screw.

Be provided with Z-shaped waterproof junction plate between the described plastic-steel plate upper and lower end, this Z-shaped waterproof junction plate is connected through screw with angle steel, and the lower cover of this Z-shaped waterproof junction plate is on the top of plastic-steel plate.

The beneficial effect of the utility model is: reduce on-the-spot installation procedure, accelerating construction progress greatly, and reducing cost, and effectively reduce wet trade reduces building waste, and energy-conserving and environment-protective reduce artificially, increase productivity, and are easy for installation.
