Description

Technical Field

[0001] The invention relates to the technical field of assembled concrete structures, and in particular to a core-pulling, hole-forming, and then grouting composite shear wall and a construction method thereof. Background Art

[0002] With the improvement of society's awareness of sustainable development, resource conservation, and environmental protection, as well as the strong advocacy of green buildings and intelligent construction, the construction industry urgently needs to transform to a green, low-carbon, and efficient modern construction model. The market demand for high-quality, short-term, and low-energy construction products is growing, which provides broad application prospects for the lean production of prefabricated components and the research on efficient construction technology. In this context, the development of a new type of industrialized construction system that is fast, efficient, energy-saving, and environmentally friendly has become an urgent need and an important trend in the construction industry's downturn.

[0003] At present, most prefabricated buildings adopt the sleeve grouting connection technology system, and their core components, prefabricated exterior walls, mostly adopt sandwich insulation exterior walls, which are composed of inner page panels, insulation panels, and outer page panels. The outer page panels are usually made of 50mm~60mm thick concrete, which increases the dead weight and production cost of the wall and increases the difficulty of transportation and construction. At the same time, the inner page panels and the outer page panels are connected by FRP pin connectors. The connectors bear shear loads for a long time. Under complex working conditions, there is a certain risk of falling off in the later stage.

[0004] At the same time, prefabricated exterior walls usually use sleeve grouting connections. Compared with traditional mechanical connections or welding, the material cost (including customized grouting sleeves, special grouting materials and necessary grouting equipment, etc.), on-site construction accuracy, and construction technology requirements are relatively high. In addition, the existing grouting fullness detection methods are expensive, and the current standards only require sampling detection, which cannot achieve comprehensive coverage. The quality of the building structure has problems such as unstable structural connections caused by the embedded channel structure and hole formation, and the quality of grouting generated by the prefabricated wall steel bar connection is difficult to guarantee, the connection strength is unstable, the construction quality control is difficult, and the inner leaf plate and the new composite insulation board are easily connected to form a thermal bridge.

[0005] Therefore, it is necessary to propose a new type of core-pulling and hole-forming grouting composite shear wall to solve the problems of quality and cost of traditional prefabricated exterior walls of assembled buildings. Summary of the invention

[0006] In view of the problems in the related art, the present invention proposes a core-drawing hole-forming and then grouting composite shear wall and a construction method to overcome the above-mentioned technical problems existing in the existing related art.

[0007] To this end, the specific technical solution adopted by the present invention is as follows: A core-pulling and hole-forming post-grouting composite shear wall comprises an inner page plate and, the composite insulation plate is connected to one side of the inner page plate, the inner page plate comprises reinforcement, vertical channel anchoring steel bars, spiral stirrups, a gourd-shaped cavity with vertical holes, and post-cast concrete, a plurality of gourd-shaped cavities with vertical holes are provided in the post-cast concrete, the spiral stirrups are provided on the outside of the gourd-shaped cavity with vertical holes, the vertical channel anchoring steel bars are provided at the ends of the gourd-shaped cavity with vertical holes, concrete is poured between the inner wall of the gourd-shaped cavity with vertical holes and the vertical channel anchoring steel bars, and a plurality of groups of reinforcement are also provided in the post-cast concrete.

[0008] Preferably, the gourd-shaped cavity with vertical holes comprises a plurality of gourd cavities and a plurality of vertical channels that are distributed at intervals in the vertical direction, and the gourd cavities and the vertical channels are connected.

[0009] Preferably, the composite insulation board includes an insulation board and a polymer cement mortar composite fiberglass mesh, a plurality of inner reserved grooves of the insulation board are opened on the connecting surface of the insulation board and the inner page board, the inner reserved grooves of the insulation board are filled with concrete to form an inner concrete bonding layer, a plurality of long strip-shaped outer reserved grooves of the insulation board are evenly opened on the other side of the insulation board, the outer reserved grooves of the insulation board are filled with polymer cement mortar to form an outer concrete bonding layer, and the polymer cement mortar composite fiberglass mesh is provided on the outside of the insulation board.

[0010] Preferably, a plurality of reserved grooves on the inner side of the insulation board are evenly distributed along the length direction and the width direction of the inner page board surface.

[0011] Preferably, a plurality of the grooves reserved on the outer side of the insulation board are consistent with the length direction of the insulation board, and the grooves reserved on the outer side of the insulation board are equal in length to the length of the insulation board.

[0012] Preferably, the spacing between two adjacent reserved grooves on the outer sides of the insulation boards is 300 mm.

[0013] According to another aspect of the present invention, a method for constructing a superimposed shear wall by grouting after core pulling and drilling is provided, which is used for constructing a superimposed shear wall by grouting after core pulling and drilling, and comprises the following steps: Insulation board slotting: the production worker opens several long strip-shaped insulation board outer side reserved grooves along the length direction of the insulation board at a spacing of 300mm on one side of its outer surface. After the long strip-shaped insulation board outer side reserved grooves are opened, the production worker opens the insulation board inner side reserved grooves with a small upper opening and a large lower opening on the other outer surface of the insulation board along the inner length and width direction of the insulation board at a spacing of 300mm. Filling and pouring: filling polymer cement mortar in the reserved groove outside the long strip insulation board to form an outer concrete bonding layer, and pouring polymer cement mortar composite glass fiber mesh on the outside of the insulation board to form a new composite insulation board; The production workers support the inner blade mold, tie the reinforcement in the supported inner blade mold, install several gourd-shaped core molds in the supported inner blade mold, then install the spiral stirrups on the outside of the vertical channel of the gourd-shaped core mold, and place the gourd-shaped core mold and the spiral stirrups on the outside inside the inner blade mold according to the design requirements. After the placement is completed, start to inflate and finalize; Concrete pouring: hoist the assembled inner blade mold above the composite insulation board, then pour the post-pour concrete into the inner blade mold, and fill the post-pour concrete into the reserved groove inside the insulation board on the insulation board to form an inner concrete bonding layer. The inner concrete bonding layer anchors the insulation board and the inner blade together to form an anchor-free connection; After the inner blade concrete reaches a certain strength, the gourd-shaped core mold is deflated and removed to form a gourd-shaped cavity with vertical holes.

[0014] The beneficial effects of the present invention are: 1. The construction method of the present invention adopts an inflatable core mold to be embedded in the assembled concrete shear wall. After the core is pulled out, a gourd-shaped channel with vertical holes is formed. Spiral stirrups are placed on the outside of the vertical hole channel to avoid loose concrete pouring on the outside of the channel. At the same time, the weak position of the channel can be locally strengthened. The gourd-shaped channel with vertical holes formed can greatly improve the anchoring force between the channel and the post-cast concrete pouring area. The structure is stable and the force is reasonable, which solves the problems of the structure and hole-forming process of the embedded channel.

[0015] 2.
