Effectively shorten the construction period, the smooth realization to project overall goals acts on the preventer of obvious overhead welding construction.
The technical solution of the utility model is as follows：
The preventer of above-mentioned overhead welding construction is tight including type steel skeleton, glass fibre flameproof fabric, shrouding and positioning
Firmware；The type steel skeleton is in integrally arch structure and is welded using shaped steel, and which 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；By positioning fastening between the shrouding and the type steel skeleton
The detachable assembly connection of part, is also uniformly provided with bar shaped installing hole on the shrouding；The positioned fastener includes positioning angle steel
And securing member, the screwed hole matched with the securing member is offered on the positioning angle steel, the positioning angle steel is welded and fixed
In the type steel skeleton inner frame；The shrouding is by loading the fastening into the screwed hole and bar shaped installing hole
Part realizes assembly connection with the type steel skeleton, and by the position of shrouding described in the bar shaped installing hole Reasonable adjustment.
The preventer of the overhead welding construction, wherein：The type steel skeleton includes a pair vertical skeletons vertically arranged
With the top slat iron for being connected to the pair of vertical skeleton top.
The preventer of the overhead welding construction, wherein：Reserve between the type steel skeleton and soldered main structure body
There is the gap of 250mm.
Beneficial effect：
It is this utility model reasonable in design, compact, using dark group last year, reliability, it is ensured that steel case sagitta missing solder is connected on
General wind, rainy day gas are normally carried out, and effectively shorten the construction period, to item on the premise of welding quality, construction safety is ensured
The smooth realization effect of mesh overall goals is obvious.The fabrication scheme of rib structure is encircleed according to steel case, each steel case encircles rib structure
Several making piecemeals need to be divided into and manufacture is completed in maker respectively, then divided making piecemeal is hung respectively in bridge location
Position is set, each two makes the bridge location seam for forming a steel case arch between piecemeal.In the design of bridge location seaming position, install a set of
Preventer, forms a relative closing space, reaches the effect of Radix Saposhnikoviae, rain-proof, and preventer material therefor is fire prevention
Material, possesses fire prevention effect, using safety, rationally, it is ensured that live overhead welding construction quality, improves efficiency of construction.Together
When, this utility model fusion high-altitude construction fireproofing technique provides strong safety guarantee for overhead welding construction.Main innovation
Point：1. simple structure, makes easy；2. construction space sealing effectiveness is relatively good, and welding quality is greatly improved；3. using crane
Moved integrally, recycling frequency is very high, greatly reduces operating expenses；4. it is easy to operate；5. main body needs welded
Structure is not damaged.

Specific embodiment
As shown in Fig. 1 to 8, the preventer of this utility model overhead welding construction, including type steel skeleton 1, glass fibre
Flameproof fabric 2, shrouding 3 and positioned fastener 4.
1 entirety of type steel skeleton is in arch structure and is welded using shaped steel, including the vertical skeletons of a pair vertical arrangements
11 and it is connected to the top slat iron 12 on a pair vertical 11 tops of skeleton.In order to the displacement for ensureing preventer it is convenient, the type steel skeleton 1 with
The gap of 250mm is reserved between soldered main structure body.
The glass fibre flameproof fabric 2 is wrapped in the outside of the type steel skeleton 1, there is fire during preventing welding procedure
