Description
Technical field
Radix Saposhnikoviae when the present invention relates to steel box arch bridge bridge location overhead welding construction operation, fire prevention, the safe construction such as rainproof
Technical field, can be widely used for the construction of steel box arch bridge bridge location, is specifically related to the preventer of a kind of overhead welding construction.
Background technology
Steel case arch structure is a kind of version commonly used in current bridge structure, and its interface type of attachment includes
Be welded to connect, bolt connects and three kinds of forms of bolting and welding.Owing to steel case arch structure is attractive in appearance, increasing municipal administration bridge work
Cheng Jun uses this version to increase urban look.Owing to steel case arch bridge is big relative to general bridge structure construction difficulty, and
Municipal works serve primarily in urban area, the target of government, the restriction of traffic, convenient civic requirement, the work of municipal works
Phase typically will not be oversize, belongs to the project type of " short, flat, fast ", makes the difficulty of construction of steel case arch bridge strengthen further, especially with
It is welded to connect the structure for interface shape the most obvious.And welding job is the highest to the requirement of construction environment, especially to rainwater
Especially sensitive with wind, therefore, employed in welding procedure (especially overhead welding construction) rainproof, draught exclusion device is non-the normally off
Key.
Summary of the invention
For the problems referred to above, the present invention proposes a kind of reasonable in design, compact, uses and secretly organizes last year, reliable, can protect
Card steel case sagitta missing solder is connected on general wind, rainy day gas is normally carried out, on the premise of ensureing welding quality, construction safety effectively
Shorten the construction period, the preventer to the smooth realization effect obvious overhead welding construction of project overall goals.
Technical scheme is as follows:
The preventer of above-mentioned overhead welding construction is tight including type steel skeleton, glass fibre flameproof fabric, shrouding and location
Firmware；Described type steel skeleton entirety is in arch structure and uses shaped steel to be welded, reserved between itself and soldered main structure body
There is gap；Described glass fibre flameproof fabric is wrapped in outside described type steel skeleton；Described shrouding is detachable is installed in described type
In gap reserved between steel skeleton and soldered main structure body；Fastened by location between described shrouding and described type steel skeleton
The detachable assembly connection of part, described shrouding is also uniformly provided with bar shaped installing hole；Described positioned fastener includes positioning angle steel
And securing member, described location angle steel offers the screwed hole matched with described securing member, described location angle steel is welded and fixed
In described type steel skeleton inner frame；Described shrouding is by loading described fastening in described screwed hole and bar shaped installing hole
Part and described type steel skeleton realize assembly connection, and by the position of shrouding described in described bar shaped installing hole Reasonable adjustment.
The preventer of described overhead welding construction, wherein: described type steel skeleton includes a pair vertical skeleton vertically arranged
With the top slat iron being connected to the pair of vertical skeleton top.
The preventer of described overhead welding construction, wherein: reserved between described type steel skeleton and soldered main structure body
There is the gap of 250mm.
Beneficial effect:
Present configuration is reasonable in design, compact, uses and secretly organizes last year, reliable, it is ensured that steel case sagitta missing solder is connected on typically
Wind, rainy day gas be normally carried out, effectively shorten the construction period on the premise of welding quality, construction safety ensureing, whole to project
The smooth realization effect of body target is obvious.According to the fabrication scheme of steel case arch rib structure, each steel case arch rib structure need to divide
Become several to make piecemeal to complete to manufacture at maker respectively, then at bridge location, divided making piecemeal is carried out lifting respectively and determine
Position, each two makes the bridge location seam forming a steel case arch between piecemeal.In the design of bridge location seaming position, a set of protection is installed
Device, forms a relative closing space, reaches Radix Saposhnikoviae, rainproof effect, and preventer material therefor is fire proofing material,
Possess fire prevention effect, use safely, rationally, it is ensured that on-the-spot overhead welding construction quality, improve efficiency of construction.Meanwhile, originally
High-altitude construction fireproofing technique is merged in invention, provides strong safety guarantee for overhead welding construction.Main innovation point: 1. structure
Simply, make easily；2. construction space sealing effectiveness is relatively good, and welding quality is greatly improved；3. may utilize crane and carry out entirety
Mobile, recycle frequency the highest, greatly reduce operating expenses；The most easy to operate；5. the agent structure needing welding is not had
Damage.

Detailed description of the invention
As Fig. 1 is to shown in 8, and the preventer of overhead welding of the present invention construction, including type steel skeleton 1, glass fibre fire prevention
Cloth 2, shrouding 3 and positioned fastener 4.
This type steel skeleton 1 entirety is arch structure and uses shaped steel to be welded, including a pair vertical vertical skeleton arranged
11 and be connected to a pair indulge the top slat iron 12 on skeleton 11 top.Convenient in order to ensure the displacement of preventer, this type steel skeleton 1 with
It is soldered the gap being reserved with 250mm between main structure body.
This glass fibre flameproof fabric 2 is wrapped in the outside of this type steel skeleton 1, to prevent breaking out of fire during welding procedure
Cause security incident.
This shrouding 3 (can be wooden) is detachable to be installed between this type steel skeleton 1 and soldered main structure body in advance
Protection in the gap stayed, during welding procedure；Wherein, this shrouding 3 is uniformly provided with multiple bar shaped installing hole 31, its
