Description
Technical field
The present invention relates to the safe constructions such as windproof, fire prevention during steel box arch bridge bridge location overhead welding construction operation, rain-proof
Technical field, it can be widely used for the construction of steel box arch bridge bridge location, and in particular to a kind of protector of overhead welding construction.
Background technology
Steel case arch structure is a kind of structure type generally used in current bridge structure, and its interface type of attachment includes
It is welded to connect, three kinds of forms of bolt connection and bolting and welding.Because steel case arch structure is attractive in appearance, increasing municipal bridge work
Cheng Jun uses this structure type to increase urban landscape.Because steel case arch bridge is big relative to general bridge structure construction difficulty, and
Municipal works serve primarily in urban area, and the target of government, the limiting of traffic, convenient civic requires, the work of municipal works
Phase typically will not be oversize, belongs to the project type of " short, flat, fast ", the difficulty of construction of steel case arch bridge is further increased, especially with
It is welded to connect the most obvious for the structure of interface shape.And requirement of the welding job to construction environment is especially high, especially to rainwater
Especially sensitive with wind, therefore, rain-proof, draught exclusion device employed in welding procedure (especially overhead welding construction) are closed very much
Key.
The content of the invention
In view of the above-mentioned problems, the present invention proposes a kind of reasonable in design, compact, using dark group last year, reliable, can protect
Steel case sagitta missing solder is connected in general wind to card, rainy day gas is normally carried out, on the premise of welding quality, construction safety is ensured effectively
Shorten the construction period, the smooth realization to project overall goals acts on the protector of obvious overhead welding construction.
Technical scheme is as follows：
The protector of above-mentioned overhead welding construction, including type steel skeleton, glass fibre flameproof fabric, shrouding and positioning are tight
Firmware；The type steel skeleton is integrally welded in arch structure and using shaped steel, and it is reserved between soldered main structure body
There is gap；The glass fibre flameproof fabric is wrapped on the outside of the type steel skeleton；The shrouding is detachable to be installed in the type
In the gap reserved between steel skeleton and soldered main structure body；Fastened between the shrouding and the type steel skeleton by positioning
The detachable assembly connection of part, bar shaped mounting hole is also uniformly provided with the shrouding；The positioned fastener includes positioning angle steel
And fastener, described position offer the screwed hole to match with the fastener on angle steel, the positioning angle steel is welded and fixed
In in the type steel skeleton inner frame；The shrouding is by loading the fastening into the screwed hole and bar shaped mounting hole
Part realizes assembly connection with the type steel skeleton, and passes through the position of shrouding described in the bar shaped mounting hole Reasonable adjustment.
The protector of the overhead welding construction, wherein：The type steel skeleton includes a pair of vertical skeletons arranged vertically
With the top slat iron for being connected to the pair of vertical skeleton top.
The protector of the overhead welding construction, wherein：Reserved between the type steel skeleton and soldered main structure body
There is 250mm gap.
Beneficial effect：
The present invention is reasonable in design, compact, using dark group last year, reliably, it is ensured that steel case sagitta missing solder is connected on typically
Wind, rainy day gas be normally carried out, ensureing welding quality, effectively shortening the construction period on the premise of construction safety, it is whole to project
The smooth realization effect of body target is obvious.Encircle the fabrication scheme of rib structure according to steel case, each steel case arch rib structure need to divide
Complete to manufacture in manufactory respectively into several making piecemeals, then carry out lifting respectively by divided making piecemeal in bridge location and determine
Position, each two form the bridge location seam that a steel case encircles between making piecemeal.In the design of bridge location seaming position, a set of protection is installed
Device, a relative closing space being formed, reaches windproof, rain-proof effect, protector material therefor is fire proofing material,
Possess fire prevention effect, it is safe to use, reasonable, live overhead welding construction quality is ensure that, improves efficiency of construction.Meanwhile this
Invention fusion high-altitude construction fireproofing technique, strong safety guarantee is provided for overhead welding construction.Main innovation point：1. structure
Simply, it is easy to make；2. construction space sealing effectiveness is relatively good, welding quality is greatly improved；3. carried out using crane overall
Mobile, recycling frequency is very high, greatly reduces operating expenses；It is 4. easy to operate；5. the agent structure welded to needs does not have
Damage.

Embodiment
As shown in Fig. 1 to Fig. 8 the protector of overhead welding construction of the present invention, including the fire prevention of type steel skeleton 1, glass fibre
Cloth 2, shrouding 3 and positioned fastener 4.
The type steel skeleton 1 is overall to be welded in arch structure and using shaped steel, including the vertical skeleton arranged vertically for a pair
11 and it is connected to the top slat irons 12 on a pair of vertical tops of skeleton 11.In order to ensure that the displacement of protector is convenient, the type steel skeleton 1 with
250mm gap is reserved between soldered main structure body.
The glass fibre flameproof fabric 2 is wrapped in the outside of the type steel skeleton 1, to prevent that fire occurs during welding procedure
Cause security incident.
The shrouding 3 (can be wooden) is detachable to be installed between the type steel skeleton 1 and soldered main structure body in advance
In the gap stayed, for the protection during welding procedure；Wherein, multiple bar shaped mounting holes 31 are uniformly provided with the shrouding 3, its
It can in real time be adjusted according to the condition of construction in closing space, reach internal smoke evacuation and require；Meanwhile for present on protector
Asbestos cloth can be used to be blocked for a small amount of gap.
The shrouding 3 is realized with the connection of type steel skeleton 1 using positioned fastener 4；Wherein, the positioned fastener 4 includes
Angle steel 41 and fastener 42 are positioned, the screwed hole 411 to match with fastener 42 is offered on the positioning angle steel 41, positions angle steel
41 temporary welds are fixed on type steel skeleton 1；The shrouding 3 is directed at the screwed hole 411 of positioning angle steel 41 by bar shaped mounting hole 31,
The shrouding 3 is to complete assembly connection with type steel skeleton 1 by loading fastener 42 into screwed hole 411 and bar shaped mounting hole 31,
And have using the position of the Reasonable adjustment shrouding 3 of bar shaped mounting hole 31, during use using it is light, quick the characteristics of.
The present invention is reasonable in design, compact, using dark group last year, reliably, it is ensured that steel case sagitta missing solder is connected on typically
Wind, rainy day gas be normally carried out, ensureing welding quality, effectively shortening the construction period on the premise of construction safety, it is whole to project
The smooth realization effect of body target is obvious.
