Along with the increasing development of national economy, the construction safety consciousness of the building engineering is improved, and the safety protection requirement is higher and higher. In the building engineering work progress, building engineering faces limit portion position and has certain potential safety hazard, has the risk factor of certain degree, need carry out safety protection to the building engineering that entrance to a cave or edge are not convenient for set up the pole setting for this reason, faces limit safety protection railing and is a common use's way. The existing holes and the safety protection railings which are not convenient to arrange the vertical rods have various connection forms, but most of the connection and erection forms are inconvenient to construct and operate, cannot be repeatedly used and damage a base layer, so that a large amount of manpower and material resources are consumed in the construction of the edge safety protection, and even safety accidents can be caused.
SUMMERY OF THE UTILITY MODEL
The utility model overcomes building engineering construction safety protection still needs the problem of improving among the prior art, provides an operation and convenient to use, and the installation and the dismantlement of being convenient for, but reuse's steel construction bridge faces frontier defense guardrail.
The technical solution of the utility model is that, a steel structure bridge faces frontier defense guardrail with following structure is provided: contain protection montant, protection horizontal pole and montant connecting piece, wherein protection montant and protection horizontal pole are alternately arranged, and the cross section passes through connector link fixed connection, and the steel sheet in protection montant and steel construction bridge pterygoid lamina edge is connected to the montant connecting piece.
Preferably, the vertical rod connecting piece comprises 2 occlusion clamping plates and clamping devices, wherein one end of each occlusion clamping plate is vertically connected with the bottom of the protective vertical rod, an occlusion opening is formed in the middle of the other end of each occlusion clamping plate, the clamping devices are arranged on the outer sides of the occlusion clamping plates and located on the upper side and the lower side of the occlusion opening respectively, each clamping device is a nut and bolt combined piece, and the annular side edge of each nut is connected to the occlusion clamping plate.
Preferably, the included angle between the occlusal splint and the center line of the occlusal notch is alpha, wherein the alpha is more than or equal to 20 degrees and less than or equal to 40 degrees.
Preferably, the inner side surfaces of the occlusion gaps are respectively provided with an antiskid projection.
Preferably, the top of the bolt is provided with an internal hexagonal interface.
Preferably, the protection vertical rods and the protection transverse rods are all hollow round steel tubes.
Compared with the prior art, the utility model discloses steel construction bridge faces frontier defense guardrail has following advantage: protection horizontal pole and protection montant are connected each other through the connecting piece, form the guardrail of standard, the interlock opening that sets up on the interlock splint matches the pterygoid lamina of bridge edge, finally can guarantee the straightness that hangs down of protection montant, the non-skid protrusions can make the frictional force between non-skid opening and the pterygoid lamina bigger, the bolt is through fastening moderately, the inseparable degree of centre gripping of junction department has been increased, hexagonal interface makes things convenient for the workman to consolidate with interior hexagonal spanner in the top surface setting of bolt, and be difficult to drop at first half bolt reinforcement's in-process.
Drawings
Fig. 1 is one of the schematic structural diagrams of the working state of the present invention;
fig. 2 is a second schematic view of the working state structure of the present invention;
fig. 3 is a schematic diagram of the top surface structure of the bolt of the present invention.
In the description of the attached drawings, the number 1 is a protective cross rod, the number 2 is a protective vertical rod, the number 3 is a bridge, the number 4 is a wing plate, the number 5 is an occlusion splint, the number 6 is an anti-skid bump, the number 7 is a bolt, the number 8 is an occlusion opening, the number 9 is a nut, and the number 10 is an internal hexagonal connector.
Detailed Description
The following combines the figure and the embodiment is right the utility model discloses steel structure bridge faces frontier defense guardrail and makes further explanation: as shown in the figure, contain protection montant 2, protection horizontal pole 1 and montant connecting piece in this embodiment, wherein protection montant 2 and the 1 cross arrangement of protection horizontal pole, the cross section passes through connector link fixed connection, and the montant connecting piece is connected the steel sheet of 4 edges of protection montant 2 and 3 pterygoid laminas of steel construction bridge. The connecting buckle comprises a right-angle buckle (cross buckle), a rotating buckle (universal buckle) and a butt buckle (straight buckle: inner pipe joint and outer pipe joint).
The vertical rod connecting piece comprises occlusion clamping plates 5 and clamping devices, wherein the number of the occlusion clamping plates 5 is 2, one end of each occlusion clamping plate is respectively and vertically connected with the bottom of the protective vertical rod 2, an occlusion opening 8 is formed in the middle of the other end of each occlusion clamping plate 5, the clamping devices are arranged on the outer sides of each occlusion clamping plate 5 and are respectively located on the upper side and the lower side of the occlusion opening 8, each clamping device is a combined piece of a nut 9 and a bolt 7, and the annular side edge of each nut 9 is connected to the occlusion clamping plate 5.
Need insert on 3 one side pterygoid lamina 4's of bridge inclined plane with the opening of interlock splint 5 of the 2 lower parts of protection montant when using, then rock more abundant that makes it link up, the workman is wearing under the condition of safety rope this moment, lie prone on one side of bridge 3, bolt 7 through interior hexagonal spanner with pterygoid lamina 4 top is screwed up, because when the edge of pterygoid lamina 4 was regarded as the rotation fulcrum, protection montant 2 can hang down under the action of gravity, then the opposite side of preventing the interlock splint 5 then rises relatively, bolt 7 of first one this moment just can play the reinforcing effect to strengthening, make the stability of junction strengthen greatly.
