Description
Technical field
The utility model belongs to a kind of connected node structure of diaphragm wall and basement structure top board, can be applied to adopting in the foundation pit supporting project of " two wall unifications " diaphragm wall.
Background technology
Diaphragm wall have anti-side rigidity large, can effectively control the many advantages such as foundation pit deformation protection surrounding enviroment and construction technology maturation, require to have obtained a large amount of application in base pit engineering high and that the excavation of foundation pit degree of depth is darker in surrounding enviroment protection in recent years.Consider from the angle of saving construction costs, the overwhelming majority selects diaphragm wall all to adopt " two wall unifications " pattern as the engineering of supporting and protection structure, and diaphragm wall, in the Foundation Pit Construction stage as supporting and protection structure, plays the object of gear soil and sealing; As main body basement structure outer wall, outer wall of underground structure is set no longer in addition in the permanent operational phase of structure.For strengthening the integral rigidity of basement structure, meet stressed and waterproof requirement, " two wall unifications " diaphragm wall is effectively connected with main body underground structure inner horizontal beam slab, structural stud and sole plate by corresponding structure node is set.In the base pit engineering of implementing along the practice, because diaphragm wall and top Guan Liang thereof constructed in the excavation of foundation pit stage, and basement structure top board is construction in later period, conventional way is the basement construction stage to connect body of wall or beam on Guan Liang, and basement structure top board reinforcing bar is anchored into and connect in body of wall or beam.When basement structure top board framework bottom elevation is during lower than hat beam face absolute altitude, way is watered and is connect in body of wall or structural beams after structural beams bottom surface reinforcing bar cannot being anchored into routinely, in common engineering, adopt Guan Liang is partly or entirely cut, together again build with basement structure beam slab, so that basement roof Bar Anchorage.For the larger engineering of foundation ditch area, this huge loss that first cuts the method for reforming afterwards and not only cause manpower and materials, also can cause the delay of programming.
Utility model content
Technical problem to be solved in the utility model has been to provide the connected node structure of a kind of diaphragm wall Guan Liang and basement structure top board, this connection is configured to arrange inverted L-shaped structure ring beam between diaphragm wall Guan Liang and structure roof, the two is effectively connected by inverted L-shaped ring beam, avoid Guan Liang to cut.
For solving the problems of the technologies described above, basic scheme of the present utility model is: Guan Liang is positioned at the top of diaphragm wall, pilaster is affixed on the inner side of described diaphragm wall, diaphragm wall is " two wall unifications " body of wall, reinforced concrete structure ring beam is arranged between described Guan Liang and steel concrete basement structure top board and is fixed together, described ring beam is inverted L-shaped, interior breach tips upside down on described Guan Liang, the vertical limb frame of described ring beam is in described pilaster, and with described pilaster uniform thickness, the face absolute altitude of described ring beam is with the face absolute altitude of described basement structure top board, the vertical limb depth of section of described ring beam is not less than the Vierendeel girder depth of section of described basement structure top board.
In the utility model, the sectional dimension of ring beam is determined jointly by Vierendeel girder height, hat beam cross sectional dimensions and the pilaster thickness of basement structure top board, the beam reinforced steel bar of basement structure top board anchor in ring beam and with ring beam synchronous construction, ring beam can be connected with Guan Liang by reserved steel bar, and the connected mode between each member belongs to prior art.In the basement roof construction stage, reserved steel bar is stripped out and anchored in ring beam.Between hat back portion and ring beam, rubber fastening band can be set, guarantee the stagnant water effect between constuction joint.
Due to the use of above-mentioned diaphragm wall Guan Liang and basement structure top board connected node structure, realizing Guan Liang is connected with the effective of basement structure top board, avoid cutting of Guan Liang, saved a large amount of man power and materials, make base pit engineering and Underground Construction more efficient.

Detailed description of the invention
The utility model is applied in the foundation pit supporting project of employing " two wall unifications " diaphragm wall, by being set, inverted L-shaped structure ring beam diaphragm wall Guan Liang effectively can be connected with basement structure top board, avoid cutting Guan Liang, play the effect of convenient construction, saving cost.By reference to the accompanying drawings, specific descriptions are as follows:
As shown in Figure 1, inverted L-shaped structure ring beam 3 is arranged between the hat beam 1 and basement structure top board 4 on diaphragm wall 2 wall tops, the beam reinforced steel bar 8 of basement structure top board 4 anchor in ring beam 3 and with ring beam 3 synchronous constructions, ring beam 3 is by vertical connecting reinforcement 6, level connection joint reinforcing bar 7 and be preced with beam 1 and be connected.
As shown in Figure 2, Figure 3 and Figure 4, the hat beam 1 of diaphragm wall can be reserved vertical connecting reinforcement 6 and level connection joint reinforcing bar 7 in the time of construction; Vertical connecting reinforcement 6 is arranged at hat beam 1 top, and its bottom, top anchor into respectively in hat beam 1 and ring beam 3; Level connection joint reinforcing bar 7 is arranged at hat beam 1 and meets hole side, and one end anchors in hat beam 1, and the other end bends and is positioned over hat beam 1 and meets in the side concrete cover of hole; Diameter, spacing and the anchorage depth of vertical connecting reinforcement 6 and level connection joint reinforcing bar 7 should be by calculative determinations.
