[0002] Prefabricated concrete structural components of houses, as an indispensable part of construction sites, have occupied a place in the construction industry with their unique advantages. They have won the favor of many builders with their simple assembly method, efficient installation speed, and easy recycling and disassembly. At the same time, the use of these prefabricated concrete structural components has also greatly promoted the implementation of environmental protection concepts in the construction field, and has played a positive role in reducing the generation of construction waste and the waste of resources.

[0003] However, despite the many advantages of prefabricated concrete structural components for houses, there is a common problem with the products on the market today, that is, the structural design is relatively simple. This simplicity leads to the connection between prefabricated concrete structural components being not strong enough, which seriously affects the overall stability of the house made up of these components.

[0038] The frame column 1 and the frame column 1 are respectively composed of an exterior decoration layer, an exterior wall waterproof layer, a thermal insulation layer, a high-strength concrete layer, and an interior decoration layer from the outside to the inside. The high-strength concrete layer of the frame beam 2 and the frame column 1 is provided with a steel plate layer, steel plate outer stirrups, and an inner steel cage;

[0039] The wall 3 is provided with a blocking laminated layer around it, and a polyethylene nostril foam strip is pre-embedded on the blocking laminated layer to form a waterproof measure combining structural waterproofing and material waterproofing;

[0040] The wall 3 is a lightweight high-strength wall and a shear wall. The wall 3 is composed of an exterior decoration layer, an exterior wall waterproof layer, a high-strength concrete layer, a lightweight high-strength foamed concrete layer, and an interior decoration layer from the outside to the inside. A double-layer high-strength fiber mesh tensile resistance layer is provided in the high-strength concrete layer of the wall 3;

[0041] The U-shaped steel bars 8 are exposed on four sides of the floor slab 4, which are combined with the U-shaped steel bars 8 on the frame beam 2, and 4 steel bars are inserted for binding connection; a post-cast strip 9 is formed between the frame beam 2 and the floor slab 4, and between the floor slabs 4, and a sealing overlap layer is provided below the floor slab 4;

[0042] After the wall 3 and floor slab 4 are inserted into the dovetail groove cavities 10 on the frame beam 2 and the frame column 1, they are connected by bolts 6 and cast to form a mortise and tenon structure.

[0043] The frame beam 2 and the frame column 1 are provided with a leveling device 11 .

[0044] The thickness of the sealing superimposed layer of the floor slab 4 is 10-15 cm.

[0045] The exterior decoration layer is one of ceramic tile, real stone paint and exterior wall paint.

[0046] The sealing superimposed layer around the wall 3 is 3 cm long and 3 cm thick.

[0047] The frame beam 2 and the steel bars in the frame column 1 are connected by a sleeve 7 .

[0048] The specific implementation process of the present invention is as follows:

[0049] 1. Excavate the foundation and make column foundation and raft foundation first.

[0050] 2. Reserve steel plates to embed socket box-type steel plate connectors on the foundation, and first connect the ground beams to the socket box-type connectors (the connectors are connected to the external ground beams and the internal ground beams).

[0051] Connection method of column connector and ground beam: first insert the frame beam into the beam-column connector, then connect the external steel plate with the bolts of the steel plate, and then connect the internal steel bar of the beam with the sleeve of the steel bar. After the connector and ground beam are fully connected, install the floor slab on the ground beam, leave a post-cast strip between the floor slab and the floor slab, and between the floor slab and the box-type steel plate connector, and then pour high-strength steel fiber fine stone concrete. First pour the connector and ground beam, then pour the post-cast strip between the ground beam and the floor slab, and wait for it to solidify to reach the required strength after pouring.

[0052] 3. Install the frame column. Insert the frame column on the upper part of the embedded box-type steel plate connector. The upper steel plate mouth of the connector is 30 degrees beveled to facilitate the insertion of the box-type frame column. After the insertion is aligned, first insert the M20 10.9 grade high-strength screw and tighten it. Then use the fastener to level and straighten the box-type frame column with high-strength bolts on the built-in leveling device inside the frame. Then tighten the high-strength bolts to tighten it. Then, connect the pre-sleeved steel sleeve on the steel bar of the steel plate connector with the steel bar on the upper frame column. Then, use bolts to connect the three-sided opening on the plugging plate, reserve a 10-centimeter post-casting circular mouth on one of the plugging plates, insert the trumpet-mouthed pouring device to pour high-strength steel fiber fine stone concrete, and after the initial setting reaches the strength, pull out the trumpet-mouthed pouring device and repair the post-casting reserved mouth.

[0053] 4. Hoist the frame beam. The steel plate connector of the frame column has a 30-degree groove to facilitate the insertion of the box-type frame beam. After the insertion is aligned, first insert the M20 10.9-grade high-strength screw, tighten it in place with a fastener, and then use the pre-sleeved steel sleeve on the steel bar on the connector inside the frame column to connect and tighten it with the steel bar on the parallel frame beam.

[0054] 5. Wall hoisting. When the wall is prefabricated in the factory, a 3 cm long and 3 cm thick sealing superposition layer is prefabricated on the four sides of the wall. A polyethylene closed-cell foam strip pad is pre-embedded on this 3 cm sealing superposition layer to form a waterproof measure that combines structural waterproofing and material waterproofing, forming multiple waterproof measures for the exterior wall and frame structure. After the wall is hoisted and inserted into the designated position, the M16 high-strength screw is passed through the prefabricated steel plate holes on the frame column, and penetrated into the high-strength nut on the reserved steel plate on the sealing plate in the wall, and initially tightened. After all the penetrations are completed, they are finally tightened. An operating seam of 10-20 cm is formed between the column and the wall, and between the beam and the wall in the upper, lower, left and right directions inside the wall. After the wall is inserted, the U-shaped steel bars on the four sides of the wall are combined with the U-shaped steel bars on the column and beam, and 4 steel bars are inserted for binding connection. After the connection is completed, the movable connecting plate of the wall is used to bolt and seal the 10-20 cm operating gap between the column and the wall, and between the beam and the wall. Finally, a dovetail groove cavity will be formed between the wall and the column and beam, so that the wall, column and beam are first bolted, and then the steel bars connecting the wall, column and beam are tied, and finally the dovetail groove cavity module is post-cast and then the mortise and tenon structure is formed. Such a post-cast mortise and tenon structure is easy to operate and has good stability.

[0055] 6. Floor slab hoisting. Hoist the floor slab and insert it onto the designated beam. After the floor slab is inserted, the U-shaped steel bars exposed on the four sides of the floor slab are combined with the U-shaped steel bars on the beam, and 4 steel bars are inserted for binding connection. After the connection is completed, a post-cast strip is formed between the beam and the floor slab, and between the floor slabs. There is a floor slab between the floor slabs, and there is a 10-20 cm sealing overlap layer underneath, which can replace the formwork for post-casting of post-cast strip concrete. After the installation of the columns, beams, walls, and floor slabs is completed, there is an open circular hole at the bottom of the frame beam that is connected to the dovetail groove cavity module of the wall, so that the post-cast high-strength steel fiber fine stone concrete can form a whole.

[0056] The strength, seismic resistance and stability of this structure are better than those of existing cast-in-place concrete structures.

[0057] Steel plates are pre-buried in the waistline, eaves, windows, doorways, and column openings of the house, such as at the eaves of door and window columns, to facilitate quick installation of the lines.

[0058] The exterior decoration layer of the exterior wall has been completed in the factory and is protected by a protective film. After the lines are installed, structural glue is injected into the joints between columns and beams, beams and walls, and columns and walls to complete the secondary material waterproofing of the joints and beautify the exterior decoration layer of the joints.

[0059] The pre-embedded integrated water and electricity pipelines and wire boxes and other water and electricity devices can be modified in any part of the wall and floor slab, and they have been prefabricated in the factory and assembled on site. The thickness of the floor slab is 10-15 cm. There is a post-cast strip on the edge of the floor slab. The window frame has been prefabricated on the wall in the factory and is protected by a film.

[0060] The assembly rate of this structure and walls, floor beams, columns and exterior wall decoration can be as high as over 95%.

[0061] From outside to inside, the columns and beams are composed of 1 exterior decorative layer (ceramic tiles, real stone paint, exterior wall paint, etc.), 2 exterior wall waterproof layer, 3 thermal insulation layer, 4 high-strength concrete (including steel pipe layer, steel pipe outer stirrups, inner steel cage), and 5 interior decoration layer.

[0062] The lightweight high-strength wall is composed of 1 exterior decoration layer (ceramic tiles, real stone paint, exterior wall paint, etc.) 2 exterior wall waterproof layer 3 high-strength concrete (including double-layer high-strength fiber grid tensile resistance layer) 4 lightweight high-strength foamed concrete 5 interior decoration layer

[0063] From the outside to the inside, the floor slabs and shear walls are composed of 1 exterior finishing layer (ceramic tiles, real stone paint, exterior wall paint, etc.) 2 high-strength concrete containing a double-layer steel cage.

[0064] Advantages of this structure:

[0065] High structural strength, good structural stability, strong seismic resistance, good anti-corrosion performance, good fire resistance, good thermal insulation and sound insulation performance, short construction period, low project cost, long service life, high safety factor, green, low-carbon and environmentally friendly.

[0066] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
