Description
Technical field
The utility model belongs to water conservancy and hydropower the realm of building construction, is related to the template load-carrying members of architectural engineering, especially
The working template load-carrying members of hanging concrete structured beam.
Background technique
In the prior art, the common support for shuttering structure of concrete structure single-beam has following several：
1. stiff skeleton formwork, which is Liang Zhongshe property skeleton without a break, this skeleton frame (can be ox in two ends
Leg is similar) on.The self weight of concrete, template, reinforcing bar etc. and construction loads (including aisle weight, construction personnel's self weight etc.) by
This stiff skeleton undertakes.Stiff skeleton is steel construction, is usually made of fashioned iron.Stiff skeleton presses the force analysis of beam, and foundation
The size of power chooses fashioned iron specification.Stiff skeleton pours into the concrete of beam, does not further take out recycling, thus cost compared with
It is high.
2. bottom truss formwork, which is only placed in stiff skeleton below beam similar to stiff skeleton formwork.It is mixed
The self weight of solidifying soil, template, reinforcing bar etc. and construction loads (including aisle weight, construction personnel be self-possessed etc.) thus structure (bracket+steel
Structure) it undertakes.Formwork is steel construction, is usually welded or is bolted by fashioned iron.Steel structure truss, usually by fashioned iron system
At.The force analysis of beam is pressed, and chooses the specification size of fashioned iron according to the size of power.After beam construction, the support for shuttering
Dismountable, the reason of this support for shuttering is because of load-bearing, material selection fashioned iron is higher in cost.
3. full support for shuttering, sets up a scaffold, from substrate (roofing, ground below beam etc.) to beam bottom.Concrete,
The self weight of template, reinforcing bar etc. and construction loads (including aisle weight, construction personnel's self weight etc.) are undertaken by scaffold.According to beam
Length is different from section, and the load handed down is different, and scaffold upright rod stress is limitation, by adjusting between upright bar
Away from come the size that meets top power.It is intuitively：When beam section size is big, bar is with regard to closeer.Scaffold uses fastener steel tube, material
Material repeats turnover utilization rate height, and material is also most common, but the material that full hall frame structure itself needs is more, and overlaps expense
When it is laborious.
Formwork erecting structure in above several common single-beams constructions exist difficulty of construction is big, it is costly, set up it is complicated it is laborious,
Long in time limit, hanging device requires high difficulty of construction.Especially in the situation that single-beam position is high, span is big, especially highlight
It is at high cost due to building to state conventional support for shuttering structure, builds period length and causes waste economically.
Utility model content
The purpose of the utility model is to provide the template load-bearing of a kind of template for bearing cast-in-situ concrete beam and construction loads
Structure.
Specifically, the utility model provides a kind of template load-carrying members, for bear cast-in-situ concrete beam template and
Construction loads, wherein template load-carrying members are equipped with two truss structures；Every truss structure by beam framework of steel reinforcement and reinforcing bar web member group
At；It is connected between two truss structure by framework of steel reinforcement stirrup.
Further, the framework of steel reinforcement includes top bars and lower layer's reinforcing bar；The reinforcing bar web member is connected to upper layer steel
Between muscle and lower layer's reinforcing bar.
Further, the reinforcing bar web member is W-shaped structure between top bars and lower layer's reinforcing bar.The reinforcing bar of W-shaped structure
Web member more effectively contacts top bars and lower layer's reinforcing bar, keeps the structure of truss more stable and solid, bearing capacity is higher.
Further, reinforcing bar web member is welded on top bars and lower layer's reinforcing bar.
In the utility model, bearing structure is to set two truss structures in every beam.Every truss structure is by beam reinforcement cages：Positioned at beam
Reinforcing bar web member (diagonal web member) is set between the top bars of side, lower layer's reinforcing bar to form, and joist steel muscles and bones is then utilized between two truss structures
The stirrup of frame contacts, and constitutes load-carrying members.
When in use, template is put by cross bar hang-up on truss, and lay-down location sets concrete pad, pad thickness and reinforcing bar
Protective layer thickness is identical, and cushion block can be prefabricated in advance, and such cross bar would not be occupied into beam body, to ensure that the matter of beam body
Amount.Multilayer steel wire, outer package steel wire, such cushion block structure, one side cushion block and concrete are equipped in prefabricated cushion block
There can be good bonding, on the other hand cushion block can be made to be unlikely to crush under biggish pressure.In the construction process, it pours
The construction loads of concrete, the concrete gravity of beam, self weight of template etc., are all born by truss.Truss and concrete reinforcement
The load-carrying members of skeleton composition, bear template, concrete gravity and construction loads of cast-in-situ concrete beam etc..It is practical by this
The construction that cast-in-situ concrete beam is completed woth no need to support for shuttering may be implemented in novel bearing structure.
Beneficial effect
The utility model forms load-bearing formwork erecting structure using the slightly a small amount of reinforcing bar of framework of steel reinforcement and welding, and traditional
Full hall support for shuttering scheme, stiff skeleton form erection plan etc. compare, and production is simple, on material can handy some waste materials, cost of manufacture
It is cheap, save setting up and dismounting workload, when the support for shuttering especially set up needed for beam position is higher is high, economy for support for shuttering
Effect is more significant.
