A kind of steel reinforcement cage main reinforcement attachment device
Technical field
The utility model belongs to steel reinforcement cage processing and fabricating field, and in particular to a kind of steel reinforcement cage main reinforcement attachment device.
Background technique
In current science of bridge building pile foundation construction, the processing of steel reinforcement cage mainly uses reinforcing bar cage seam welding to be processed, special
Property for process velocity it is fast, one class of stock and 5~7 people of roll welding part under normal circumstances, point two classes of operations, 10 people one day
The cage (stock, roll welding, reinforcing rib installation, detection pipes installation, guiding cushion block installation etc.) of more than 20 12 meters of long finished product is processed,
Working efficiency is very high.Since using do mechanization operation, main reinforcement, the spacing for winding muscle are uniform, and steel reinforcement cage diameter is consistent, produce
Code requirement is fully achieved in quality.Stirrup is not required to overlap: saving material 1% compared with handwork, reduces construction cost.?
In steel reinforcement cage processing and making process, since the progress of technology is in development, the pier stud of bridge is higher and higher, and the length of pile foundation is also more next
Bigger, due to the limitation of seam welder length, the length maximum when carrying out steel reinforcement cage processing is only 9m, and current science of bridge building
In pile foundation length it is much in 9m, provided according to bridge construction specification: the same section reinforcing bar piece-ups amount of bridge pile foundation steel reinforcement cage
No more than the 50% of splice total quantity, connector must be staggered, and the minimum range being staggered is 35 times of bar diameter and not small
In 50cm, so pile foundation biggish for length needs to carry out segmentation production, then two sections of steel reinforcement cages are connected with sleeve again
Come, when connection need to manually carry out the connection one by one of sleeve, time-consuming and laborious;Mistake is generated due to inevitable during steel bar meter
Difference often will appear corresponding steel bar end length two-by-two and mismatch so that main reinforcement accuracy in connection is poor, the length of sleeve
It is shorter, it needs to modify unmatched main reinforcement reinforcing bar before being attached using sleeve, seriously affects construction speed and construction matter
Amount.
Summary of the invention
The utility model uses easy when sleeve connection produce to solve main reinforcement during existing steel reinforcement cage processing and spreading
Raw positioning is inaccurate, constructs time-consuming and laborious, so that the problem of seriously affecting construction speed and construction quality, provides a kind of steel reinforcement cage
Main reinforcement attachment device.
The utility model is achieved by the following technical solution: a kind of steel reinforcement cage main reinforcement attachment device, including steel sleeve,
Be provided with groove in the middle part of steel sleeve, steel bushing pipe surface be located at groove both ends be symmetrical arranged there are four positioning and locking device, positioning and locking
Device includes the nut and positioning screw of mating setting, and nut-welding is fixed on steel bushing pipe surface, and positioning screw can run through steel
Sleeve surface simultaneously protrudes into steel sleeve, and reinforcing bar is inserted at steel sleeve both ends respectively, and the end of positioning screw can hold out against reinforcing bar appearance
Face realization steel sleeve is fixedly connected with reinforcing bar.
Positioning screw is perpendicular to steel sleeve axis.
It is inserted into the contact point portion in the grooves of two reinforcing bars in steel sleeve.
Steel sleeve uses seamless steel pipe processing and fabricating, and the internal diameter of steel sleeve is greater than 1~3 centimetre of bar diameter.
The steel bonding glue for being used for stiffener and steel sleeve connective stability can be injected by groove.
The specified features and beneficial effect that the utility model has compared with prior art are:
The utility model is not only simple in structure, designs rationally, and cost of manufacture is lower, and convenient positioning accurate is operated when use
Quasi-, saving manually, can greatly improve the quality and efficiency of steel reinforcement cage processing.The utility model is particularly suitable for Large-size rebar cage
Main reinforcement be connected and fixed, have stronger promotional value.
Detailed description of the invention
Fig. 1 is the structural representation front view of the utility model;
Fig. 2 is the structural representation side view of the utility model;
Fig. 3 is the structural schematic diagram under the utility model use state.
In figure: 1- steel sleeve, 2- nut, 3- positioning screw, 4- groove, 5- reinforcing bar.
Specific embodiment
The utility model is further elaborated in referring to Fig.1~Fig. 3, a kind of steel reinforcement cage main reinforcement attachment device, including steel
Casing 1, is provided with groove 4 in the middle part of steel sleeve 1, and 1 surface of steel sleeve is located at 4 both ends of groove and is symmetrical arranged that there are four positioning and lockings to fill
It sets, positioning and locking device includes the nut 2 and positioning screw 3 of mating setting, and nut 2 is weldingly fixed on 1 surface of steel sleeve, positioning
Screw rod 3 can run through 1 surface of steel sleeve and protrude into steel sleeve 1, and reinforcing bar 5 is inserted at 1 both ends of steel sleeve respectively, positioning screw 3
End can hold out against 5 outer surface of reinforcing bar and realize being fixedly connected for steel sleeve 1 and reinforcing bar 5.
When steel reinforcement cage needs spreading, prepare the utility model connection dress of identical quantity according to the main reinforcement radical of steel reinforcement cage
It sets, steel sleeve 1 uses seamless steel pipe processing and fabricating, and the internal diameter of steel sleeve 1 is greater than 1~3 centimetre of 5 diameter of reinforcing bar.This distance is same
When be also positioning screw 3 the effective length protruded into steel sleeve 1.The excessive waste that will cause steel sleeve 1 of effective length, effectively
The too small stability being screwed that will lead to of length is deteriorated.1 one end of steel sleeve of attachment device is set in steel reinforcement cage main reinforcement
One end adjust the position of two reinforcing bars 5 by another end cap of steel sleeve 1 in 5 one end of reinforcing bar for connecting of needs, from groove 4 into
Row observation guarantees that the contact point of two reinforcing bars 5 in insertion steel sleeve 1 is located at 4 middle part of groove, at this point, groove 4 is used as watch window
It carries out using there are deviations for the size that reinforcing bar 5 can be effectively prevent to be inserted into steel sleeve 1;Further, difference screwed in place screw rod
3, hold out against it with reinforcing bar 5.
In view of steel reinforcement cage main reinforcement utilizes the force stability of the utility model connection, groove 4 can be used as injecting glue window simultaneously
Mouthful use, it may be assumed that after reinforcing bar 5 is tentatively fixed by positioning bolt 3, by groove 4 inject on a small quantity can quick-drying steel bonding glue,
Steel bonding glue can effectively fill up the gap of reinforcing bar 5 Yu steel sleeve 1, be conducive to being connected and fixed for the two;Further, to positioning spiral shell
Bar 3 is twisted again, to reduce a possibility that positioning screw 3 loosens.
