Abstract
The utility model relates to a building floor construction field specifically is a bracket for roof drilling, characterized by: it includes bracing piece, action bars, connecting rod and ejector pin, wherein, the vertical setting of bracing piece, its top is rotated with connecting rod one end and is connected, and its middle part AND operation pole middle part is rotated and is connected, the vertical setting of ejector pin, its bottom AND operation pole rotates to be connected, and its middle part is rotated with the connecting rod other end and is connected, so, four members form a parallelogram linkage, and the luffing motion action bars can make the ejector pin rise or descend, top at the ejector pin is provided with a layer board, fixed connection between triangle wedge and the ejector pin through the triangle wedge. This bracket simple structure, the preparation material is convenient, the preparation of can gathering materials on the spot especially at the construction field (site), the operator can be at the lower to the roof operation of holing through it to the operation security has also improved when guaranteeing construction quality.
Description
Technical field
The utility model relates to building floor construction field, specifically a kind of bracket for top plate drilling.
Background technology
At present, in the newly-built, renovating and enlarging engineering of architectural engineering, when when needing to carry out (at the bottom of plate) steel planting, furred ceiling at the bottom of constructional column beam, the construction such as suspension rod, crane span structure suspension rod boring installation suspension rod is installed in suspension rod boring, bore operation labour intensity is large, high-altitude (place) is dangerous large, inefficiency, annoyings enterprises management of building construction personnel and workmen all the time.Traditional boring method is that a workmen ascends a height, hand-held electrician tool is passed eminence workmen by another workmen, lower workmen be energized electric tool, the hand steered electrician tool of eminence workmen one, another hand is opened the switch of electric tool and is upwards lifted and withstand electric tool.This method not only increases cost of labor, and workmen lifts and withstands electric tool and hole.The weight that the arm lifted not only will bear drilling tool also will give the jacking force that drilling tool creeps into, very easily tired aching and limp unable.Because mechanical oscillation are large when construction operation, and spirit absent-mindedness is caused to cause mechanical wounding.
Summary of the invention
The purpose of this utility model is to provide a kind of lever-type boring bar tool lifting apparatus, and so, operating personnel just can make boring bar tool lift at lower, thus improve operating efficiency and operational security.
In order to achieve the above object, the utility model is achieved in that
For a bracket for top plate drilling, it comprises support bar, action bars, connecting rod and push rod, and wherein, support bar is vertically arranged, and its top and connecting rod one end are rotationally connected, and are rotationally connected in the middle part of it with in the middle part of action bars; Push rod is vertically arranged, and is rotationally connected bottom it with action bars, is rotationally connected in the middle part of it with the connecting rod other end; So, four rod members form a parallelogram linkage, swing up and down action bars and push rod can be made to increase or decline; At the top of push rod, triangle chock is provided with one block of supporting plate, triangle chock is fixedly connected with between push rod.
This carrier structure is simple, and make material convenient, making of can gathering materials on the spot especially at the construction field (site), operator can carry out bore operation at lower to top board by it, thus also improves operational security while guarantee construction quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The utility model is further illustrated below by way of specific embodiment.
As shown in Figure 1, a kind of bracket for top plate drilling, it comprises support bar 2, action bars 1, connecting rod 3 and push rod 7, and wherein, support bar 2 is vertically arranged, and its top and connecting rod 3 one end are rotationally connected, and are rotationally connected in the middle part of it with in the middle part of action bars 1; Push rod 7 is vertically arranged, and is rotationally connected bottom it with action bars 1, is rotationally connected in the middle part of it with connecting rod 3 other end; So, four rod members form a parallelogram linkage, swing up and down action bars 1 and push rod 7 can be made to rise or decline; At the top of push rod 7, triangle chock 8 is provided with one block of supporting plate 10, triangle chock is fixedly connected with between push rod.
When this bracket uses, drilling tool afterbody and middle part are bundled on push rod 7 by belt or rope, and with plastic adhesive tape, drilling tool switch opens is wrapped on supporting plate 10, then bracket is moved at the bottom of the beam needing boring or floor slab bottoms, drilling tool is energized, downward pressing operation bar 1 makes push rod 7 rising start bore operation, after drilling depth to be done, lifts action bars 1, push rod 7 is declined, namely reaches the object of boring.
This carrier structure is simple, and make material convenient, making of can gathering materials on the spot especially at the construction field (site), operator can carry out bore operation at lower to top board by it, thus also improves operational security while guarantee construction quality.
