[0002] With the rapid development of urban construction, the demand for the development and utilization of underground space by people is increasing and becoming more urgent. Among them, in the construction process of the underground part of large buildings and underground buildings themselves, in the supporting structure of underground foundation pits, the diaphragm wall structure has been widely used due to its characteristics such as large stiffness, good integrity, and strong applicability.
[0003] Traditional diaphragm walls are mostly reinforced concrete structure walls built by in-situ casting construction. However, as a concealed project of a building, the reinforced concrete structure diaphragm wall has problems that need to be solved urgently in the process of its construction and use, such as easy deviation of the steel cage, joint mud inclusion and water leakage, concrete flow-around, intrusion (bulging), unsightliness (unable to be directly used as the outer wall of the main structure), and easy cracking on the outside. Summary of the Utility Model
[0004] The main purpose of the utility model is to propose a steel-concrete composite system for diaphragm walls and a diaphragm wall, aiming to solve the technical problems that need to be solved urgently in the process of construction and use of the existing reinforced concrete structure diaphragm wall, such as easy deviation of the steel cage, joint mud inclusion and water leakage, concrete flow-around, intrusion (bulging), unsightliness (unable to be directly used as the outer wall of the main structure), and easy cracking on the outside.

On the side of the second plate body close to the second blocking steel plate where the third card slot is located, it extends in a direction away from the corresponding second blocking steel plate to form the third connection strip. The third connection strip on any one steel plate outer skeleton can be engaged with the third card slot on the other steel plate outer skeleton in a snap-fit manner.
[0011] In one embodiment, on the side of the two second blocking steel plates facing the filling area, a plurality of reinforcing rib strips are arranged at intervals along the extending direction of the second blocking steel plates.

[0032] Please refer to Figures 1 to 7 , in an embodiment of the present utility model, the diaphragm wall steel-concrete composite system includes a plurality of steel-concrete composite structures 100, and the plurality of steel-concrete composite structures 100 are connected end to end in sequence to enclose and form the diaphragm wall steel-concrete composite system;
[0033] The steel-concrete composite structure 100 includes a steel plate outer skeleton 110 and a concrete block 120. A filling area is formed on the steel plate outer skeleton 110, and the concrete block 120 is made by casting and filling concrete materials into the filling area. The two ends of the steel plate outer skeleton 110 along its length direction are respectively a first connection position 130 and a second connection position 140. The first connection position 130 is formed with a first connection strip 111 and a first card slot 112 that are arranged at intervals along the width direction of the steel plate outer skeleton 110. The second connection position 140 is correspondingly formed with a second card slot 113 for accommodating the first connection strip 111 and a second connection strip 114 for accommodating the second card slot 113. The first connection strip 111 and the first card slot 112 on any steel plate outer skeleton 110 can be correspondingly clamped and matched with the second card slot 113 and the second connection strip 114 on another steel plate outer skeleton 110.
[0034] In this embodiment, by arranging a plurality of steel-concrete composite structures 100, the steel-concrete composite structure 100 is arranged to include a steel plate outer skeleton 110 and a concrete block 120. During use, each steel-concrete composite structure 100 is connected end to end with the second connection position 140 of another steel-concrete composite structure 100 through the correspondingly arranged first connection position 130 in sequence to enclose and form a steel-concrete composite system for diaphragm wall, so that when the present utility model is in use, problems such as deviation of the reinforcement cage, joint mud leakage, concrete flow-around, and easy cracking on the outer side of the intrusion limit can be avoided by using the arranged steel plate outer skeleton 110. At the same time, since the steel plate outer skeleton 110 is arranged on the outer side of the concrete, the overall aesthetic degree of the diaphragm wall can also be improved by using the arranged steel plate outer skeleton 110 when the present utility model is in use.
[0035] In this embodiment, the exemplary concrete material can be but is not limited to concrete above C30. In an exemplary embodiment, the steel plate outer skeleton 110 can be a steel plate arranged only on the outer periphery of the concrete block 120, and the first connection position 130 and the second connection position 140 are respectively arranged on both sides of the length direction of the first steel plate.
[0036] In some specific embodiments, the steel plate outer skeleton 110 includes two first blocking steel plates 115 and two second blocking steel plates 116. The two first blocking steel plates 115 are opposite and spaced apart along the length direction of the steel plate outer skeleton 110, and the two second blocking steel plates 116 are spaced apart at both ends of the two first blocking steel plates 115 along the width direction of the steel plate outer skeleton 110 to enclose a filling area with the two first blocking steel plates 115. The sides of the two first blocking steel plates 115 facing away from the filling area respectively form the first connection position 130 and the second connection position 140.
[0037] In this embodiment, by arranging two first blocking steel plates 115 and two second blocking steel plates 116, the function of connecting a plurality of steel-concrete composite structures 100 can be realized when the present utility model is in use. At the same time, by respectively arranging the first connection position 130 and the second connection position 140 on the two first blocking steel plates 115, and using the arranged first connection position 130 and the second connection position 140 to connect multiple steel-concrete composite structures 100, when the foundation pit is relatively deep and the geological conditions are relatively complex, the steel plate outer skeleton 110 can be used as the steel plate outer skeleton 110 of the steel-concrete composite structure 100, while in the application scenario where the foundation pit is relatively shallow and the geological conditions are good, only the outer steel plate can be used as the steel plate outer skeleton 110. In this way, under the premise of meeting different application needs and ensuring the quality requirements of the constructed diaphragm wall structure, materials can be saved and construction costs can be reduced.
[0038] In one embodiment, the two first blocking steel plates 115 are respectively a first plate body 150 and a second plate body 160, a side of the first plate body 150 away from the filling area forms a first connection position 130, a side of the first plate body 150 close to one of the second blocking steel plates 116 extends in a direction away from the corresponding second blocking steel plate 116 to form a first connecting strip 111, and the first plate body 150 is recessed in a direction toward the filling area to form a first slot 112 spaced apart from the first connecting strip 111;
[0039] The second plate body 160 forms a second connection position 140 on the side away from the filling area, and the second plate body 160 extends from the second blocking steel plate 116 on the side close to the first connecting strip 111 to the direction away from the second blocking steel plate 116 on the corresponding side to form a second slot 113, and the position of the second plate body 160 corresponding to the first slot 112 is recessed toward the filling area to form a second connecting strip 114.
[0040] In this embodiment, by adopting the steel-concrete composite structure 100, not only the tensile strength of the steel structure can be fully utilized, but also the compressive strength of the concrete can be fully utilized, thereby greatly improving its bearing capacity and crack resistance. During use, the side in contact with the soil layer is supported by an external steel plate, thereby perfectly solving the technical problem of the outer side concrete of the existing reinforced concrete underground continuous wall being prone to cracking and water seepage.
[0041] In one embodiment, a third slot 131 is formed on one side of the first plate body 150 close to another second blocking steel plate 116 and is spaced apart from the first slot 112. The second plate body 160 is close to the second blocking steel plate 116 on the side where the third slot 131 is located, and extends in a direction away from the second blocking steel plate 116 on the corresponding side to form a third connecting strip 141. The third connecting strip 141 on any steel plate outer frame 110 can be snap-fitted with the third slot 131 on the other steel plate outer frame 110.
[0042] In this embodiment, the steel-concrete composite structure 100 module adopts a structural form combining a steel plate outer skeleton 110 and concrete blocks 120. When the foundation pit is relatively deep and the geological conditions are relatively complex, by setting the steel plate outer skeleton 110, not only the steel cage structural materials in the existing reinforced concrete diaphragm wall are saved, but also the binding operation process of the steel cage is saved; and in the application scenario where the foundation pit is relatively shallow and the geological conditions are good, using the outer steel plate as the steel plate outer skeleton 110 can save materials and reduce construction costs; moreover, the steel-concrete composite structure 100 provided in this embodiment can be prefabricated on the ground, so as to realize its high-quality, high-efficiency, factory-based and standardized batch prefabrication and rapid on-site assembly connection. Moreover, through ground prefabrication, the structural problem of its uneven surface can be solved, so that it can become a part of the permanent support structure of the relevant building in the later stage without post-treatment, meeting the requirements of saving and economy, etc.
[0043] On one side of the two second blocking steel plates 116 facing the filling area, a plurality of reinforcing rib strips 132 are arranged at intervals along the extending direction of the second blocking steel plates 116. A plurality of reinforcing steel sections 134 are arranged at intervals along the length direction of the second blocking steel plates 116 in the filling area, and the reinforcing steel sections 134 and the reinforcing rib strips 132 are arranged at intervals. A plurality of tenon columns 135 are arranged at intervals along the length direction of the second blocking steel plates 116 in the filling area, and the plurality of tenon columns 135 are arranged at intervals with the tenon columns 135.
[0044] In one embodiment, a plurality of first connection grooves 136 are formed at intervals at the top of the steel-concrete composite structure 100, and a first connection column 137 with the same number as the first connection grooves 136 and arranged in one-to-one correspondence is formed at the bottom of the steel-concrete composite structure 100. The first connection groove 136 on any steel-concrete composite structure 100 can be correspondingly connected with the first connection column 137 on another steel-concrete composite structure 100.
[0045] In this embodiment, by adopting the set splicing method, not only the functions of load transfer and water stop are achieved, but for the vertical connection, not only the splicing members are used to realize the superposition splicing of the upper and lower modules, but also the steel plate outer skeletons 110 of the two steel-concrete composite structures 100 are welded, so as to not only improve the integrity between the modules, but also improve its anti-seepage performance.
[0046] In one embodiment, a plurality of second connection grooves 138 are formed at intervals at the top of the steel-concrete composite structure 100, the second connection grooves 138 are arranged at intervals with the first connection grooves 136, and a second connection column 139 with the same number as the second connection grooves 138 and arranged in one-to-one correspondence is formed at the bottom of the steel-concrete composite structure 100. The second connection column 139 is arranged at intervals with the first connection column 137. The second connection groove 138 on any steel-concrete composite structure 100 can be correspondingly connected with the second connection column 139 on another steel-concrete composite structure 100.
[0047] In this embodiment, an up-and-down splicing method is adopted, so that the upper and lower adjacent steel-concrete composite structure 100 modules can be stacked and spliced vertically, continuously spliced horizontally, and combined with each other vertically and horizontally, enabling them to form a diaphragm wall with a continuous and complete structure, improving the integrity and impermeability of the diaphragm wall.
[0048] Based on the same technical concept, in a second aspect, the present utility model provides a diaphragm wall, which applies the steel-concrete composite system of the diaphragm wall in the first aspect.
