Abstract
The utility model relates to a tenon type joint of precast steel bar concrete for an underground continuous wall, which is preformed by mixing steel bars and concrete. The utility model has the structure that two short side faces of a sliver-shaped ventral plate are respectively connected with the middle of the long side face of a sliver-shaped flange to form an approximate H-shaped sliver-shaped tenon type joint. The tenon type joint does not need to be drawn out after the unit groove section of the underground wall is poured with concrete and can be combined with the poured underground wall into a whole, so the anti-leakage property of the underground wall is enhanced. When the underground wall is constructed, the utility model saves manpower and material resources, reduces the cost and accelerates the engineering progress. The tenon type joint of precast steel bar concrete for an underground continuous wall can be popularized and used in all places where underground continuous walls are built.
Description
The utility model relates to a kind of joint of diaphragm wall, refers in particular to a kind of prefabricated reinforced concrete tenon formula joint.
Development along with urban renewal and urban construction, the construction of continuous concrete wall that adopts in the deep pit digging is extensive day by day in engineering construction, and existing original foundation ditch list retaining wall develops into double " three-in-one " body of wall of doing load-bearing and basement structure wall, therefore, more and more higher to the requirement of the construction quality of underground diaphragm wall and speed.For satisfying this requirement, construction technology commonly used at present is such: subterranean wall is divided into some unit groove sections, the steel fore shaft pipe of the groove section two ends vertical installation code of each unit groove section behind fluting, carrying out concrete then in the groove section builds, treat with equipment steel fore shaft pipe to be extracted gradually after concrete is solidified to certain hour, and then carry out the operation of next groove section.There is following shortcoming in this technology: the one, and the weight of steel fore shaft pipe own is bigger, after the concrete initial set, carry out underground demoulding lifting and need the special pulling machine of large-tonnage, and extubation time also is subjected to the concrete restriction of time of setting, if tube drawing can cause that the concrete of pipe nearside collapses, and has influenced joint quality too early; If crossing slow tube drawing can cause demoulding difficulty and be difficult for stirring, in the practice of construction since the accident that the fore shaft pipe that human factor or mechanical breakdown cause is set in the concrete happen occasionally, not only influence workmanship, and because fore shaft pipe cost height has caused bigger waste.The 2nd, the fore shaft pipe can make cast-in-place concrete cause in various degree damage in the process of extracting, and often forms joint folder mud, leaks or quality problems such as local concrete is outstanding.In sum, when building diaphragm wall, utilize the unit groove section form of construction work of extracting joint, because its long construction period, labour intensity is big and quality can not get guaranteeing, progressively not welcome by Construction Party and unit in charge of construction.
The purpose of this utility model is to design a kind of construct when building diaphragm wall simple, save trouble and labor, and the anti-leakage performance is strong, can improve the diaphragm wall prefabricated reinforced concrete tenon formula joint diaphragm wall total quality and that can save cost.
The purpose of this utility model is to realize like this, diaphragm wall prefabricated reinforced concrete tenon formula joint is prefabricated into tenon formula joint by concrete and many reinforcing bars mixing, wherein tenon formula joint be configured to that each is connected with the middle part of the long side surface on a block length bar edge of a wing in two short sides of a block length bar web, forms one closely
The strip tenon formula joint of type, on a horizontal plane, the both wings acies face of the other end is on a horizontal plane and place web end face between two edges of a wing to stretch out to protrude in both wings acies face at the both wings acies face of an end on the horizontal plane or wherein and web end face for the both wings acies face that is shaped as every end of the both ends of the surface of tenon formula joint and web end face.Form a tenon.
When in building diaphragm wall, using precast reinforced tenon formula joint of the present utility model to substitute used steel fore shaft pipe, because this tenon formula joint needn't be extracted, can with after the subterranean wall of watering coagulate integrator, eliminated the folder mud and the infiltration phenomenon of the seam crossing of subterranean wall and joint, and near
The tenon notch type section of type has further improved the shearing resistance interlock performance and the water resistance of joint, therefore, this construction technology has improved the anti-leakage performance of diaphragm wall greatly, in addition, because this tenon formula joint needn't be extracted, human and material resources have both been saved, reduced construction cost, accelerated the progress of engineering again greatly, therefore, this prefabricated reinforced concrete tenon formula joint suits to promote the use of in the place of all construction diaphragm walls.
Details are as follows to structure of the present utility model below with reference to the accompanying drawing of two embodiment:
Fig. 1 is the structure chart of the tenon formula joint of one of embodiment of the present utility model;
Fig. 2 is the structure chart of two the tenon formula joint of embodiment of the present utility model;
Fig. 3 is the cross section view of the joint of tenon formula shown in Fig. 1 and Fig. 2;
Fig. 4 is the structural behavior figure when Fig. 1 is connected use when building than deep underground continuous wall with two kinds of tenon formula joints shown in Fig. 2.
Structure of the present utility model is referring to Fig. 1-Fig. 3, diaphragm wall prefabricated reinforced concrete tenon formula joint is prefabricated into by concrete 7 and many reinforcing bars 6 mixing, wherein tenon formula joint be configured to that each is connected with the middle part of the long side surface on a block length bar edge of a wing 3 in two short sides of a block length bar web 4, forms one closely
The strip tenon formula joint of type, the both ends of the surface of tenon formula joint can be made following two kinds of shapes, a kind of shape is referring to the tenon formula joint 1 of one of embodiment of the present utility model among Fig. 1, the end face on two edges of a wing 3 of the every end in the both ends of the surface of tenon formula joint 1 and the end face of web 4 are on a horizontal plane, another kind of shape is referring to two the tenon formula joint 2 of embodiment of the present utility model among Fig. 2, the end face on two edges of a wing 3 of a wherein end of the both ends of the surface of tenon formula joint 2 and the end face of web 4 are on a horizontal plane, the end face on two edges of a wing 3 of the other end is on a horizontal plane and place the end face of the web 4 between two edges of a wing 3 to stretch out to protrude in the end face on two edges of a wing 3, form a tenon, if when building the diaphragm wall of the general degree of depth, as long as use one one end that the tenon formula joint 2 of tenon is arranged, will have an end of tenon imbed the underground just can be easily fixing tenon formula joint; If when building darker diaphragm wall, because it is not too convenient to make long tenon formula joint, can connect with many tenon formula joints and use, Fig. 4 is with two, below a tenon formula joint 2 that uses a butt face that tenon is arranged, above a tenon formula joint 1 that uses two ends all to be the plane, can also connect with tenon formula joint 1 above as required.In order further to improve the water resistance of tenon formula joint, respectively be inlaid with the rubber 5 that slow swollen characteristic is arranged in two outsides that the web 4 of tenon formula joint 1 and tenon formula joint 2 is connected with two edges of a wing 3, this rubber 5 can expand when meeting water, has strengthened the waterproof effect of diaphragm wall.
