It is reinforced in such a way that reinforcing bar is welded with Leak-tight liner channel steel, this method is time-consuming, takes object, is laborious, while work progress difficulty
Greatly, the quality of reinforcing is difficult to control, once serious consequence will be caused by falling off.
Utility model content
Technical problem to be solved in the utility model is that existing reactor building primary containment one side formwork top adds
Gu work progress difficulty is big, operation is time-consuming and laborious, and its purpose is to provide a kind of containment one side formwork top bracing means, should
Structure can reduce the reinforcing difficulty in primary containment one side formwork work progress, improve construction efficiency, save construction cost.
The utility model is achieved through the following technical solutions：
A kind of containment one side formwork top bracing means, including pull rod are fixed with and Leak-tight liner channel steel on the pull rod
The gib head of fastening is cased on pull rod and is arranged in fastener and hook with the fixed fastener of formwork reinforcement steel back rib, formwork reinforcement steel back rib
Between head.Reactor current workshop primary containment one side formwork top carries out in such a way that reinforcing bar is welded with Leak-tight liner channel steel
It reinforces, this ruggedized construction belongs to fixed reinforcing, and bonding area is small, more demanding for welding quality, once there is solder skip
Or solder joint is uneven, it is inconsistent to may result in the stress being subject at reinforcing, causes to fall off, and the quality reinforced is not achieved and wants
Ask, once serious consequence will be caused by falling off, while, there is open fire generation in while welding, there are security risk, it is comprehensive for, this reinforcing
Mode is time-consuming, take object, laborious, also causes that work progress difficulty is big, and the efficiency of construction is low, and this programme is then by using fastening
Mode, i.e., first the pull rod of high intensity and gib head are welded and fixed in builder's temporary shed, bonding area is big and not easily to fall off, then by hook
Head is buckled on Leak-tight liner channel steel, then is tensed pull rod to realize by rotary buckle, to which gib head and Leak-tight liner channel steel be fastened,
It can ensure that pull rod is in tension and reaches consolidation effect, the difficulty of reinforcing reduces, and improves construction efficiency, while can be into
Row dismounting enables structure to reuse, and has saved construction cost.
In order to realize consolidation effect, the groove of Leak-tight liner channel steel insertion, the size of groove are recessed in the bottom of gib head
It is mutually matched with Leak-tight liner channel steel, depth enough in this way is inserted into convenient for Leak-tight liner channel steel, while ensureing to will not fall off when using
And shaking, strengthening quality are met the requirements.
The intensity that pull rod can be influenced when pull rod size is long, be easy to cause deformation, so being cased with reinforcing cone on pull rod
Body, and the larger one end in cone end face is reinforced towards gib head or fastener, the intensity of pull rod can be increased in this way, reduce its deformation
Probability when actually being installed, is reinforced cone and is provided at pull rod center and between gib head and formwork reinforcement steel back rib.
In order to ensure clasping effects, is slided after preventing pull rod from positioning and be provided with fastener, fastener includes backing plate and locking screw
Mother, and backing plate and locking nut are sleeved on pull rod, backing plate is arranged between formwork reinforcement steel back rib and locking nut.Utilize lock
Backing plate is pressed on formwork reinforcement steel back rib by tight nut rotation, prevents from reinforcing back stay movement, guarantee pull rod has enough
Tension dynamics, while adjusting template verticality and sectional dimension.
The utility model compared with prior art, has the following advantages and advantages：The utility model can be reduced
Reinforcing difficulty in primary containment one side formwork work progress, primary containment one side formwork top consolidation time is compared to original
There is reinforcing mode to shorten 24 hours, improve construction efficiency, and bracing means can be utilized repeatedly, the apparent satisfaction of concrete is tested
Receipts standard, which save construction costs.
