Description
Technical field:
The utility model relates to reserved opening protection technology fields, and in particular to a kind of telescopic reserved opening horizontal protective
Bracket.
Background technique:
" construction safety inspection is implemented by People's Republic of China's house and the publication of town and country construction portion from July 1st, 2012
Look into standard ", number JGJ/59-2011 has increased the related content of construction safety newly on the basis of original regulation, and the 3.13.3 articles
Regulation: the holes such as reserved opening, elevator shaft mouth of project under construction should take safeguard procedures, further emphasize hole protection.Closely
Nian Lai, with the continuous expansion of construction market scale, building structure construction also more complicated multiplicity, the various peaces for facing side, hole
Full accident happens occasionally, and the accident frequency for occurring high falling in whole building construction accident, in elevator shaft also increases.Cause
This, the protection inside and outside the elevator of skyscraper is the most important thing of current construction site security protection.
But from the point of view of the actual conditions of current each construction site, protection and operating platform in elevator mainly utilize steel
Pipe, fastener set up into derrick type frame body, and security protection requirement is generally all not achieved.Some construction enterprises, in order to reduce cost,
Also the operating platform of packaged type is set up into the elevator shaft of construction site using steel pipe, but due to unreasonable structure, is existed
Security risk.Due to being connected using steel pipe with fastener, stress point is shelved on the concrete building plate face of elevator door opening, and another side leans against
On the metope of the concrete hoistway of Core Walls Structure, though taking low inside and high outside, and anti-fall measure is taken in door opening, set up again above
At operating platform.But due to using the steel pipe of Ф 48 for main stressed member, fastener is easy to happen steel pipe change as connector
Shape, fastener loosen sliding, and structural system is destroyed, and high fall accident will occur.Currently, protecting existing construction site in elevator
It mostly uses steel pipe to set up greatly, and does not take every layer of setting, but interlayer is taken to be arranged, most of protection is also taken every two layers
Setting hard protection and horizontal protective match, and cannot have enough to meet the need utilization well, waste manpower and material resources.
Utility model content:
The purpose of this utility model is exactly in order to make up for the deficiencies of the prior art, to provide a kind of telescopic hole to be provided saliva
Flat protective stent, it have many advantages, such as it is simple and reasonable, easy to install and use, adjustable, can be recycled, solve existing
There is the problem of technology.
Used technical solution is the utility model to solve above-mentioned technical problem:
A kind of telescopic reserved opening horizontal protective bracket, including the rectangle shielded frame being made of four L-type side frames, institute
The protection plain net of rectangle shielded frame can be covered by stating rectangle shielded frame and being equipped with, four side of protection plain net respectively with L-type
Frame connection, L-type side frame both ends end are respectively equipped with connecting plate, and connecting plate is equipped with connecting hole, and adjacent two connecting plate is logical
Bolt is overregulated to connect with adjusting nut.
The L-type side frame is made of angle steel.
The hook of installation protection plain net is respectively equipped on the lateral wall of L-type side frame both ends.
The adjusting bolt is equipped with adjusting nut A, adjusting nut B and adjusting nut C, the adjusting nut A and adjusts
Bolt cooperation is fastened on a connecting plate, and adjusting nut B and adjusting nut C cooperation are fastened on another connecting plate.
The utility model using the above scheme, for existing reserved opening, devises a kind of flexible
Formula reserved opening horizontal protective bracket, by designing four L-type side frames, realization quickly assembles rectangular shielded frame, and installation is torn open
It unloads conveniently；Realize the connection of two L-type side frames by adjusting bolt and adjusting nut, and can according to the size of reserved opening into
Row adjusts the size of rectangle shielded frame.
Detailed description of the invention:

Wherein, 1, L-type side frame, 2, rectangle protective stent, 3, protection plain net, 4, connecting plate, 5, connecting hole, 6, adjusting spiral shell
Bolt, 7, adjusting nut A, 8, adjusting nut B, 9, adjusting nut C, 10, hook, 11, reserved opening.
Specific embodiment:
The utility model is described further with embodiment with reference to the accompanying drawing:
As shown in Figure 1-3, a kind of telescopic reserved opening horizontal protective bracket, including the square being made of four L-type side frames 1
Shape shielded frame 2, rectangle shielded frame 2 are equipped with the protection plain net 3 that can cover rectangle shielded frame 2, protect 3 four side of plain net
It is connect respectively with L-type side frame 1,1 both ends end of L-type side frame is respectively equipped with connecting plate 4, and connecting plate 4 is equipped with connecting hole 5, adjacent
Two connecting plates 4 are connected by adjusting bolt 6 with adjusting nut.By designing four L-type side frames 1, realization quickly assembles rectangular
Shielded frame 2, it is easy for assemble or unload；The connection of two L-type side frames 1 is realized by adjusting bolt 6 and adjusting nut.
L-type side frame 1 is made of angle steel.Structural strength is high, at low cost.
The hook 10 of installation protection plain net 3 is respectively equipped on 1 both ends lateral wall of L-type side frame, convenient for protecting plain net 3 to installation
With plain net 3 will be protected to even up.
As illustrated in figures 4-5, it adjusts bolt 6 and is equipped with adjusting nut A7, adjusting nut B8 and adjusting nut C9, adjusting nut
A7 and the adjusting cooperation of bolt 6 are fastened on a connecting plate 4, and adjusting nut B8 and adjusting nut C9 cooperation are fastened on another company
On fishplate bar 4.By installing three adjusting nuts on adjusting bolt 6, realization, can when adjusting 2 size of rectangle shielded frame
Two spaced L-type side frames 1 can be connected firmly.
Above-mentioned specific embodiment cannot function as the limitation to scope of protection of the utility model, for the skill of the art
For art personnel, any alternate modification or transformation made to the utility model embodiment all fall within the guarantor of the utility model
It protects in range.
Place is not described in detail for the utility model, is the well-known technique of those skilled in the art of the present technique.
