Description
Technical field
The utility model relates to.A kind of side horizontal protective that faces having enough to meet the need pacifies tear steel tube fastener open fastly, public civil buildings room
Side horizontal safety guard rail is faced at interior construction hole
Background technique
Side horizontal protective railing (horizontal steel tube) is faced at traditional architecture indoor construction hole, according to facing side dimension of opening demand
It sets up, is stayed in advance in concrete column wall or ground and set built-in fitting and be connected and fixed with vertical steel pipe, then using the double fastener pipe threads in right angle
By vertical steel pipe and horizontal steel tube assembly and connection, side hole horizontal protective railing is faced in formation.The method defect is as follows: 1, needing preparatory
Buying production built-in fitting, when construction, need to increase installation of embedded parts process, increase construction cost；2, horizontal protective steel pipe two sides need to increase
Add two vertical steel pipes to be first connected and fixed with built-in fitting, horizontal protective steel pipe could be connected later；3, edge protection is set up
The double fastener pipe thread higher costs in the right angle Shi Caiyong, amortization charge are high.
Summary of the invention
In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide one kind can have enough to meet the need to face side horizontal protective fast
Peace tears steel tube fastener open, and solid and reliable, installing and dismounting is simple, repeatable to be used in turn.
To achieve the above object, the utility model is achieved through the following technical solutions:
A kind of side horizontal protective that faces having enough to meet the need pacifies tear steel tube fastener open fastly, including single fastener, nut, screw rod, plastic expansion
It manages, is fixedly connected with nut on the outer wall of single fastener, screw rod is double threaded screw, and screw rod one end is connect with nut, the other end and modeling
Expect expansion tube connection, the screw rod is at L-shaped.
The plastic dowel sleeve include expansion tube body, expand tube body upper section be equipped between space, space will be swollen
The upper section of tube expansion ontology is divided into two expansion tenons, is fixed with trunnion outside expansion tenon；The lower section for expanding tube body, which is equipped with, to be connected
Connect hole.
Compared with prior art, the utility model has the beneficial effects that
The side horizontal protective that faces that can be had enough to meet the need pacifies that tear steel tube fastener overall structure open simple, at low cost and light fastly, without preparatory
It is stayed in wall column or floor and sets built-in fitting, plug and play, installing and dismounting is simple, simplifies installation process, construction efficiency is improved,
It can be connect with concrete column wall using plastic dowel sleeve with the function from swollen fixation, it is solid and reliable.Cost of manufacture is lower, saves
Built-in fitting purchases cost of manufacture；It takes and has replaced vertical fixed steel pipe, saved hiring cost, it is repeatable to be used in turn, reduce construction
Cost.The production of waste steel bar head can be used in double threaded screw, accomplishes waste reclamation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: the mono- fastener 2- screw rod 3- nut 4- plastic dowel sleeve 5- nozzle 6- expansion tenon 7- trunnion of 1-.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings of the specification, it should be noted that the utility model
Implement embodiment not limited to the following.
See Fig. 1, a kind of side horizontal protective that faces having enough to meet the need pacifies tear steel tube fastener open fastly, including single fastener 1, nut 3, screw rod 2,
Plastic dowel sleeve 4, nut 3 is fixedly connected on the outer wall of single fastener 1, and screw rod 2 is double threaded screw 2,2 one end of screw rod and nut 3
Connection, the other end are connect with plastic dowel sleeve 4, and the screw rod 2 is at L-shaped.
Plastic dowel sleeve 4 includes expansion tube body, expand tube body upper section be equipped between space, space is by expansion tube sheet
The upper section of body is divided into two expansion tenons 6, is fixed with trunnion 7 outside expansion tenon 6；The lower section for expanding tube body is equipped with connection
Hole.Single fastener 1 can be purchased directly, and single fastener 1 is made of fixed part and movable part, and fixed part one end and movable part are hinged, fixed
Portion's other end is bolted with movable part, and fixed part and movable part close intermediate formation nozzle 5 after button, for installing steel pipe.
When production, screw rod 2 is at L-shaped using 6 diameter waste steel bar 90-degree bent shape of Φ, then is all made of rolling at L shape reinforcing bar both ends
Silk machine rolled thread screw thread, the connecting hole of longer one end insertion plastic dowel sleeve 4 of L shape reinforcing bar, single 1 back side of fastener and steel spiral shell
Female 3 firm weldings are facing side hole two sides concrete wall column using percussive drilling, the reinforcing bar for connecting plastic dowel sleeve 4 are being inserted into
After in hole, fixation is screwed clockwise, then steel nut 3 is connect with the reinforcing bar other end, the pipe by horizontal steel tube directly with single fastener 1
Mouthfuls 5 connections form interim horizontal protective, and when dismounting is removed piece by piece by installation reverse order, and plastic dowel sleeve 4 can stay in
In concrete.
The double fasteners of original cross are changed to single fastener 1 by the utility model, and the cost of material is low and light；Face side hole level
Two sides vertical steel pipe has been saved in setting up for protection, saves rental charge；Buying, production, installation built-in fitting process are reduced, material is reduced
Cost；Quick for installation, disassembly is simple, saves cost of labor, lifting construction efficiency.
