Description

Building faces side modular guard railing

Technical field

The utility model is related to a kind of safety protection facility of construction site use and in particular to a kind of building faces side combination Formula guard rail.

Background technology

With the expansion of construction scope, security incident is also to take place frequently, and causes very to the personal property of China builder Major injury, the raising of awareness of safety is very urgent.Require according to country is relevant, excavation of foundation pit, project under construction face side hole all Need to carry out security protection, typically we carry out scene protection using guard rail.

Guard rail is that a kind of common tubing connects product, how to build temporarily, is easy to play provisional protection Effect, improves the security of job site.Present guard rail is typically made up of tubing and joint, wherein tubing include crossbeam and Cylindrical vertical tube, in order to preferably increase stability, the structure of guard rail is made using metal material entirely.Wherein, many water The upper and lower arranged for interval of flat crossbeam, many vertical tubes are plugged in the middle of crossbeam along vertical direction interval, are connected formation one with crossbeam Individual overall guard rail.For good connecting cross beam and vertical tube, how to be assembled using T-shaped type joint, abbreviation T font or Three-way connection, usually crossbeam run through the horizontal opening of T-shaped type joint, and vertical tube is fixed on the vertical openings of T-shaped type joint.And T-shaped joint is applied to horizontal basal plane, and for the place upstairs having angle of inclination, T font joint cannot be carried out connecting and fixing.

For this reason, now many connected using the pipeline that special-shaped T-shaped type joint carries out angle of inclination, special-shaped T-shaped type joint by T-shaped type joint, horizontal tube and bend pipe composition, wherein horizontal tube and bend pipe are separately mounted at the horizontal opening of T-shaped type joint, Then pass through the installing hole on horizontal tube and bend pipe surface with bolt, so that it is fixed using frictional force.So there is problems with：1st, build Build and be disposed in the outdoor the guard rail on building site more, because long wind and weather and guard rail are made up of metal material, different Connection within shape T-shaped type joint and tubing and joint, all get rusty easily, and the guard rail after getting rusty is in dismounting Very inconvenient；2nd, the fixation of joint and tubing and the fixation within joint, is all carried out by the way of bolt insertion installing hole Fixing, bolt, under wind and weather, gets rusty easily, and dismounting is inconvenient.

In addition, existing corner coupling head, including the first connector, the second connector and joint among three members, three companies It is integrated making between joint and is mutually perpendicular between any two, but corner coupling head is used in building corner by builder During connecting two sections of guard rails, it is frequently encountered orientation problem：Need to fix corner coupling head one end with one section of guard rail, Then the corner coupling head other end and another section of guard rail are fixed, and are frequently necessary in this process corner coupling head is carried out repeatedly Angle adjustment, builder generally uses brute-force or hard thing impact corner coupling head, not only have impact on construction speed, and easily Cause the damage of corner coupling head, increased cost.

Utility model content

The utility model aims to provide a kind of building and faces side modular guard railing, shortens the engineering time.

Base case：Building in this programme faces side modular guard railing, including transverse strands pipe, vertical frame pipe, is used for Guard rail corner coupling head that transverse strands pipe at corners of building, vertical frame pipe connect, for two transverse strands pipes, one vertical Guard rail T-shaped type joint that frame pipe connects, cross for two transverse strands pipes, two vertical frame pipe connection guard rails Joint and the guard rail being connected with building masonry wall for frame pipe lean on wall list joint, wherein guard rail corner coupling head Including the first connector, the second connector and joint among three members, it is vertical setting between the wherein first connector and the second connector Put, guard rail T-shaped type joint includes tee T joint body, and described tee T joint body is along horizontal direction one end Be cased with horizontal tube, the other end of tee T joint body is cased with bend pipe, the first described connector include the first inserted joint casing and Fixing first pivot fitting vertical with the first inserted joint casing, the second described connector includes the second inserted joint casing and with second The second fixing pivot fitting of inserted joint casing, the first described pivot fitting forms pivot joint with the second described pivot fitting；The It is hinged with screw-button between in the middle part of one inserted joint casing and in the middle part of the second inserted joint casing；Joint among three members includes and the first pivot fitting Connecting tube and threeth inserted joint casing fixing with connecting tube that end is detachably connected；Described elbow internal wall is provided with cushion； Described horizontal tube is divided into outer tube and inner tube, outer tube and inner tube with axis and interference fit, and the end sidewalls of said inner tube open up Jagged, the surfaces externally and internally of inner tube is cased with interior elastic layer and outer elastic layer respectively, and interior elastic layer, outer elastic layer and cushion are along axle To all offering cut-off rule.

Compared to prior art, the utility model has the advantage of：It is pivot joint between first connector and the second connector , the angle that operative employee adjusts between the first connector and the second connector according to actual conditions then can be facilitated right to realize The connection of two section guards or assembling are very convenient quick.Wherein first inserted joint casing, the 3rd inserted joint casing and a section guard Rod member is connected, and then turn screw-button is adjusted angle with the rod member of an other section guard, is aligned and goes forward side by side to the second inserted joint casing Row is connected；Whole process is convenient and swift, thus realizing quick adjustment, installing and fixing, greatly reduces the engineering time.

Additionally, compared with existing bolt connection, adopting elastic connection, horizontal tube and bend pipe all with squeezing in the utility model The mode of compression elasticity material, is changed to the contact surface between horizontal tube, bend pipe and tubing, special-shaped T-shaped type joint itself Assembling and special-shaped T-shaped type joint are convenient with the connection of tubing, good fixing effect, and it is more convenient to dismount link.With When, using elastic connection way, and it is interference fit, firm effect is more preferable.Horizontal tube is divided into outer tube and inner tube, and the side of inner tube Wall end is provided with breach, can be knocked out inner tube, outer tube and tee T using first being exerted a force to indentation, there with instrument in outer tube Reserve space between joint body, tubing, can easily outer tube be taken off very much, such dismounting mode, will not be because of The baptism of rainwater and dismantle and waste time and energy, detaching structure is ingenious, and dismantle easily save time.Due to being externally provided with interior elasticity in inner tube Layer and outer elastic layer, in unloading process, will not produce to the surface of inner tube, tubing and outer tube and scratch, be easy to reuse, Economize on resources.Cut-off rule is all offered above interior elastic layer, outer elastic layer and cushion, convenient disassembly, and reusable. It is elastic connection that the utility model mainly changes contact surface, and more preferably, do not got rusty by tubing etc. is affected firm effect, and to pipe The damage of material and joint is less, reusable；Meanwhile, structure and the dismounting mode of horizontal tube are changed, dismounting is time saving and energy saving.

The security protection facing side and hole be applied to Building Construction for the utility model, has structure letter Singly, build dismounting fast and convenient, have enough to meet the need convenient transportation, the repeatable advantage being used in turn.
