Technical field
The utility model relates to assembled arthitecutral structure, specifically a kind of assembling body of wall vertical reinforcement steel sleeve overlap joint syndeton.
Background technology
At present, in assembling frame structure, shear wall structure, the connection of reinforcing bar adopts sleeve connected mode mostly, i.e. the constraint to grouting material by sleeve makes power transmission reinforcing bar, grouting material and sleeve shaped integral, and its switching performance is good.But this sleeve and power transmission reinforcing bar all need machining screw, and offer upper and lower steam vent in cartridges sides, bring some problems to site operation, and cost cannot reduce.In addition, all there will be and easily enter the problems such as foreign material at construction middle sleeve upper and lower end, affected contacting of grouting material and sleeve, power transmission reinforcing bar, thereby reduced the switching performance of reinforcing bar.
Another kind of connected mode is uncased bar splicing mode.In this mode, common upper and lower power transmission reinforcing bar close contact, there is not a determining deviation, then concreting or grouting material form one, this form of construction work has affected concrete or grouting material contacts with the whole of power transmission reinforcing bar, cannot make concrete or grouting material and power transmission reinforcing bar form enough bond stresss, be unfavorable for the transmission of reinforcing bar longitudinal shear.
Utility model content
The technical problems to be solved in the utility model is, a kind of assembling body of wall vertical reinforcement steel sleeve overlap joint connector is provided, so that the node of assembled arthitecutral structure, seam are connected to and ensure that structure connects under safe prerequisite, greatly reduces difficulty of construction, saves cost.
The technical scheme that the utility model solves described problem employing is:
A kind of assembling body of wall vertical reinforcement steel sleeve overlap joint syndeton, comprise steel sleeve, upper body of wall vertical reinforcement, lower body of wall vertical reinforcement, band diplopore rubber location snap ring is housed respectively in the upper and lower port of described steel sleeve, described upper and lower body of wall vertical reinforcement upper and lowerly penetrates in described steel sleeve with the locating hole on the snap ring of diplopore rubber location by described respectively, between described steel sleeve and described upper and lower body of wall vertical reinforcement by fixed being integrated of high-strength grout of pouring into.
Before the construction of above-mentioned assembling body of wall vertical reinforcement steel sleeve overlap joint syndeton, should require choose reasonable steel sleeve length according to design and structure, do not need additionally machining screw on steel sleeve or body of wall vertical reinforcement, do not need to offer upper and lower steam vent as ordinary casing side, before construction, build with band diplopore rubber locator card ring seal steel sleeve lower end, play positioning wall vertical reinforcement, exhaust and prevent the effect that foreign material enter, in construction, lower body of wall vertical reinforcement is inserted in steel sleeve lower port with in the locating hole on the snap ring of diplopore rubber location, steel sleeve adopts seat slurry method guarantee steel sleeve to place safely, then another band diplopore rubber location snap ring is enclosed within on upper body of wall vertical reinforcement in advance, again upper body of wall vertical reinforcement is inserted to steel sleeve, and extend in the locating hole on the snap ring of band diplopore rubber location, lower end, pour into high-strength grout from top, after filling, build band diplopore rubber location snap ring in steel sleeve upper end, make steel sleeve, high-strength grout and upper, lower body of wall vertical reinforcement is connected to one.
The utility model that adopts technique scheme, compared with prior art, its beneficial effect is:
Do not need steel sleeve to carry out secondary operations, directly after the snap ring of capping band diplopore rubber location, use, greatly reduce construction cost and difficulty; Can play body of wall vertical reinforcement, the exhaust of intermal force and prevent that foreign material from entering by effective location with diplopore rubber location snap ring, and thering is feature easy for installation; The environmental protection of band diplopore rubber locator card has been demonstrate,proved upper and lower body of wall vertical reinforcement and has been kept a determining deviation, is beneficial to the enough bond stresss of performance between grouting material and body of wall vertical reinforcement; This structure connection procedure does not need welding, and wet trade is few, effectively ensures good reinforcing bar switching performance.
As preferably, the utility model further technical scheme is:
Described steel sleeve is seamless steel pipe or ERW.
The described external diameter with diplopore rubber location snap ring is slightly larger than described steel sleeve internal diameter, retains certain gap, to ensure effective connection the between described high-strength grout and described upper and lower body of wall vertical reinforcement between two locating holes on the snap ring of diplopore rubber location.
Described high-strength grout is the grouting material that is not less than C80.
Described high-strength grout is the strong fast duralumin acid salt cement of superelevation.
