Description
Technical field
The invention belongs to precast stair to lift field, and in particular to a kind of pre-buried lifting part of precast stair.
Background technology
Building Trade in China is chronically at labour intensive, mode of construction relatively backward conventional industries stage, traditional construction mould
Formula has the characteristic of high energy consumption, high pollution, poor efficiency, in order to change this present situation, in recent years, country greatly develop steel construction and
Assembled architecture, for response, country calls, and the assembly rate requirement that relevant policies propose new building is put into effect in various regions in succession.Wherein,
Stair are component components indispensable in building, have the features such as of single specification, easy standardization, mass production, are built in assembled
Build the primary stage of popularization and application, preferential popularization and application assembled stair, be the road for the first choice for improving assembly rate.Precast stair
Lifting mode is not perfect at present, and practices well is the pre-buried built-in fitting with bolt hole, then by the suspension ring with screw rod and in advance
Embedded part bolt connection.This way has the defects of certain, and debris is easily fallen into bolt hole, blocks bolt hole；Suspension ring and built-in fitting
During bolt connection, if worker is not carefully careful, easily there is the situation do not tightened or skidded, add the danger of lifting.
The content of the invention
To solve the above problems, the invention discloses a kind of pre-buried lifting part of precast stair, safe, lifting is convenient,
Difficulty of construction is reduced, shortens construction period.
To reach above-mentioned purpose, technical scheme is as follows：
A kind of pre-buried lifting part of precast stair, it is characterised in that：Including hanging piece, suspension rod and bottom plate, the suspension rod is vertically set on
On bottom plate, the suspension rod is cylinder, and suspension rod side is provided with symmetrical vertical slot, and a circle translot, translot top are provided with below vertical slot
Provided with locating slot, the hanging piece includes suspension ring and connecting cylinder, and the suspension ring are arranged on connecting cylinder, and connecting cylinder is lower opening
Open column shape structure, connecting cylinder inwall are provided with projection, and the quantity of the projection, position match with vertical slot.
As a modification of the present invention, the quantity of the vertical slot and locating slot is four.
As a modification of the present invention, the locating slot is square groove, and projection is square.
As a modification of the present invention, the translot is highly arranged on suspension rod 1/3 and highly located.
As a modification of the present invention, the bottom plate is square plate.
As a modification of the present invention, the suspension ring are semicircular ring.
The beneficial effects of the invention are as follows：
The pre-buried lifting part of a kind of precast stair of the present invention, connecting cylinder are connected in the locating slot of suspension rod side, security
Height, difficulty of construction is reduced, lifting is convenient, shortens construction period, and hanging piece can reclaim, and reduces cost of manufacture.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is hanging piece upward view of the present invention.
Reference numerals list：
1st, hanging piece, 2, suspension rod, 3, bottom plate, 4, vertical slot, 5, translot, 6, locating slot, 7, suspension ring, 8, connecting cylinder, 9, projection.
Embodiment
With reference to the accompanying drawings and detailed description, the present invention is furture elucidated, it should be understood that following embodiments are only
For illustrating the present invention rather than limitation the scope of the present invention.It should be noted that the word " preceding " used below in description,
" rear ", "left", "right", "up" and "down" refer to the direction in accompanying drawing, and word " interior " and " outer " refer respectively to direction or remote
From the direction of particular elements geometric center.
As illustrated, the pre-buried lifting part of a kind of precast stair of the present invention, including hanging piece 1, suspension rod 2 and bottom plate 3, institute
State suspension rod 2 to be vertically set on bottom plate 3, the suspension rod 2 is cylinder, and the side of suspension rod 2 is provided with symmetrical vertical slot 4, vertical slot lower section
Provided with a circle translot 5, locating slot 6 is provided with above translot, the hanging piece 1 includes suspension ring 7 and connecting cylinder 8, and the suspension ring 7 are arranged on
On connecting cylinder 8, connecting cylinder 8 is the open column shape structure of lower opening, and the inwall of connecting cylinder 8 is provided with projection 9, the number of the projection 9
Amount, position match with vertical slot 4.
The pre-buried lifting part of a kind of precast stair of the present invention, is embedded in stair when pouring, plane of marking time upper shed,
Suspension rod 2 is arranged in opening, and when lifting stair, connecting cylinder 8 is enclosed on suspension rod 2 from top, in translot 5 and the infall of vertical slot 4, is hung
Part 1 is rotated horizontally, and projection 9 is connected in the locating slot 6 of suspension rod side, and suspension ring are caught on suspension hook, can sling stair safely,
The present invention is safe, is not easy to slide, and reduces difficulty of construction, and lifting is convenient, shortens construction period, and lifting is hung afterwards in place
Part 2 can unclamp recovery, reduce cost of manufacture.
