Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated buildings, and in particular to a fully assembled wall panel system for a multi-story building and a construction method thereof. Background Art

[0002] In order to promote prefabricated buildings, there is an urgent need for a prefabricated construction system that is compatible with self-built houses on rural residential land.

[0003] At present, there are two mainstream market systems for prefabricated construction in rural homestead housing projects. One is a frame system based on precast concrete such as beams, columns, and slabs, and the internal and external partitions are constructed with lightweight partitions such as ALC. The other is a shear wall system based on precast concrete wall panels and fully precast floor slabs. The upper and lower left and right connections of the wall panels are connected by bolts made of steel connectors, and then supplemented with high-strength mortar or caulking materials to fill the connection positions. The first system is easy to construct and has low cost, but because the ALC lightweight partition wall is used for the outer protection, it has a high risk of water seepage, and the sound insulation and durability are not as good as the red brick walls widely used in rural areas. The second system is also easy to construct, but because the wall panels are all made of concrete materials, the cost is high, and the wall panel splicing positions are bolted, the structure cannot achieve self-waterproofing; although there are tongue-and-groove waterproofing and weather-resistant sealants as auxiliary waterproofing, the durability of weather-resistant sealants is poor, and the waterproofing effect in areas with high temperature and humidity is inevitably not as good as the wet connection method. Therefore, a wall panel assembly system that can better adapt to the prefabricated construction of rural self-built houses is needed. Summary of the invention

[0004] In order to overcome the defects of the prior art, the technical problem to be solved by the present invention is to propose a multi-story building fully assembled wall panel system and a construction method thereof, so as to increase the prefabrication rate of prefabricated buildings of rural self-built houses and improve the comfort and durability of the buildings.

[0005] To achieve this object, the present invention adopts the following technical solutions:

[0006] The present invention provides a fully assembled wall panel system for a multi-story building, comprising a plurality of shear wall panels constituting building units and a composite panel matched with the top of the shear wall panels, wherein the building units of a plurality of layers constitute a main building body along the vertical direction, and also comprise a prefabricated balcony matched with the building units, and the main building body is also provided with a prefabricated staircase for moving in the building units of different layers; a wall panel connection node is provided between two adjacent shear wall panels, and the wall panel connection node includes a flat connection portion, an angle connection portion, and a vertical connection portion according to the connection mode; a composite panel non-reinforced connection node is provided between two adjacent composite panels; a balcony connection node is provided between the prefabricated balcony and the adjacent shear wall panels and the composite panel; the prefabricated staircase comprises two, and the two prefabricated staircases are staggered in height, and a matching staircase connection node is provided in the building unit with the staircase.

[0009] When the building unit continues to be constructed layer by layer, the shear wall panels need to be vertically connected. The vertical connection part includes two shear wall panels. Several corrugated tubes are evenly pre-buried near the bottom of the shear wall panels. The plug interface of the corrugated tube leads to the bottom of the shear wall panels, and the pouring port of the corrugated tube extends to the side of the shear wall panels. Vertical connecting bars cooperating with the corrugated tubes are also pre-buried near the top of the shear wall panels. During assembly, the protruding end of the vertical connecting bar is inserted into the corrugated tube of the adjacent shear wall panel, and grouting is performed into the corrugated tube from the pouring port. Preferably, the composite plate is inserted between the two adjacent wall panels connected vertically. When the protruding end of the vertical connecting bar is inserted into the corrugated tube of the adjacent shear wall panel, the protruding end of the vertical connecting bar passes through the composite plate, and the gap between the composite plate and the shear wall panel is provided with grouting sealing material.

[0010] At the connection of the composite plates, the unreinforced connection nodes of the composite plates include edge support nodes, intermediate support nodes and close-jointed nodes. The edge support nodes are the cooperation between the edge supports and the composite plates, the intermediate support nodes are the cooperation between the two adjacent composite plates and the supports, the close-jointed nodes are the cooperation between the two adjacent composite plates, and additional steel bars are arranged at the joints of the connection points of the composite plates.

[0011] At the balcony connection, the balcony connection node includes a balcony composite plate and a balcony support that match the prefabricated balcony, and one end of the prefabricated balcony and the balcony composite plate are fixed on the balcony support in a stepped manner; it also includes additional ribs and additional distribution ribs, one end of the additional ribs is in a hook shape and overlaps the ribs of the prefabricated balcony, and the other end is tied to the additional distribution ribs, and the other end of the additional distribution ribs is matched with the balcony composite plate and tied.

[0012] At the stair connection, the stair connection node includes a top beam and a middle beam, matching welded steel plates are pre-embedded in the shear wall panels at both ends of the top beam and the middle beam, the top beam cooperates with the stair composite plate at the top of the building unit, the middle beam is arranged between the top and bottom of the building unit, one end of one prefabricated staircase is built on the top beam, and the other end is built on the middle beam, one end of another prefabricated staircase is built on the middle beam, and the other end is built on the bottom of the building unit, and the middle beam forms a transfer platform for the two prefabricated staircase supports; the prefabricated staircase is provided with pin holes at both ends near the top beam and the middle beam, and the top beam and the middle beam are fixed with stair dowels that cooperate with the pin holes, and during assembly, the stair dowels are inserted into the pin holes.

[0013] A method for constructing a fully assembled wall panel system for a multi-story building, which is used for the construction of the wall panel system described above, comprises the following steps: S00: the shear wall panels are brought into the site, after which the size of the shear wall panels is checked, the corrugated pipes are positioned, the vertical joints, the flat joints and the corner joints are positioned, and after the shear wall panels are installed in place, grouting construction is carried out, and the composite panels can be hoisted only after the grouting strength reaches the requirements; S10: after the composite panels are brought into the site, the size of the composite panels needs to be checked, and additional steel bars, additional surface bars and additional distribution bars are prepared according to the design requirements; at the same time, it should be noted that due to the connection between the composite panels and the ladder beam supports, the welding construction of the top beam and the middle beam should be completed in advance before the composite panels are hoisted; the prefabricated balcony can be hoisted after the composite panels are installed in place; S20: after the prefabricated balcony is brought into the site, the outer dimensions need to be checked, and the prefabricated balcony can be hoisted only after the composite panels are hoisted, so as to ensure the normal construction of the composite panels at the intersection of the balconies. After the prefabricated balcony is installed in place, additional surface reinforcement and additional distribution reinforcement are tied, and subsequent mechanical and electrical installation is carried out at the same time; when all the work is completed, the board surface can be poured; S30: After the board surface is poured, an effective connection is formed between the top beam and the middle beam and the shear wall panel, providing a stable working condition for the installation of the prefabricated staircase. Before hoisting the stairs, it is necessary to install the corresponding steel beam position at the pin hole and weld the staircase dowel bar. At the same time, mortar is applied to the contact position between the stairs and the steel beam for leveling. After the prefabricated stairs are installed in place, the pin hole is grouted; S40: Continue to install the next layer of the main body. After the main body is completed, the joint position needs to be processed according to the node, and the PE rod is placed in the joint of the floor slab and the wall panel when the component is installed; Among them, in step S00, when connecting vertically adjacent shear wall panels, the on-site construction must reserve the length of the vertical reinforcement in advance according to the shear wall panel installation requirements to insert the corrugated pipe.

[0014] The beneficial effects of the present invention are:

[0015] (1) This case solves the problem of poor comfort and durability caused by the use of lightweight partition walls on the exterior walls of traditional frame systems. Compared with ALC wall panels, concrete wall panels have a higher waterproof effect. Compared with bolt connections, mortar anchor lap joints have a structural self-waterproofing function, ensuring the waterproof performance of the building in long-term use. Compared with ALC wall panels, this system uses concrete shear wall panels, which can effectively reduce the propagation of sound waves and improve living comfort and durability.

[0016] (2) Based on the characteristics of prefabricated buildings in rural houses, this solution can also avoid the problem of wall columns needing to be cast in situ when the shear wall system of high-rise residential buildings is constructed in an assembled manner, further improve the prefabrication rate of buildings, reduce carbon emissions, and be more suitable for the needs of rural buildings.

[0046] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0047] like Figure 1As shown, the present invention provides a multi-story building fully assembled wall panel system, including a plurality of shear wall panels 11 constituting building units 1 and a composite panel 12 matched with the top of the shear wall panels 11, the shear wall panels 11 are concrete wall panels, a plurality of layers of building units 1 form a building body 10 along the vertical direction, and also include a prefabricated balcony 13 matched with the building unit 1, and the building body 10 is also provided with a prefabricated staircase 14 for moving in the building units 1 of different layers; further, a wall panel connection node 2 is provided between two adjacent shear wall panels 11, and the wall panel connection node 2 includes a flat connection portion 21, a corner connection portion 22, and a vertical connection portion 23 according to the connection mode; specifically, when two shear wall panels 11 are horizontally connected, that is, the straight sections of the two shear wall panels 11 are spliced ​​together, such as Figure 2 and Figure 4 As shown, the butt joint 21 includes two shear wall panels 11 and butt joint ribs 211. The assembly ends of the two shear wall panels 11 are evenly provided with a plurality of butt joint steel wire ropes 212 along the vertical direction. The free ends of the butt joint steel wire ropes 212 exposed after bending are in the shape of a rope loop, and the other end is anchored in the shear wall panel 11. The free ends of the butt joint steel wire ropes 212 of the two shear wall panels 11 are staggered in the vertical direction to avoid mutual interference. In order to facilitate subsequent grouting, the matching ends of the two shear wall panels 11 can also be provided with grooves sloping to both sides to match the butt joint steel wire ropes 212. During assembly, the butt joint ribs 211 are inserted into the rope loops of the free ends of the butt joint steel wire ropes 212 of the two matching shear wall panels 11; finally, fine stone concrete is poured in the cavity formed by the grooves of the two shear wall panels 11, so that the two shear wall panels 11 can transmit horizontal forces. PE rods 6 are arranged along the vertical seams on the outdoor side so that weather-resistant sealant can be applied later to enhance the waterproof effect of the joints;

[0048] When two shear wall panels 11 are connected at an angle vertically, that is, when a corner connection is performed, the end surface of one shear wall panel 11 is connected to the side surface of another shear wall panel 11, such as Figure 5 and Figure 7As shown, the corner joint 22 includes two shear wall panels 11 and corner reinforcement 221, wherein a plurality of corner steel wire ropes 222 are evenly arranged at the assembly end of one shear wall panel 11 in the vertical direction, the free end of the corner steel wire rope 222 exposed after bending is in the shape of a rope loop, and the other end is anchored in the shear wall panel 11; a plurality of open stirrups 223 cooperating with the free end of the corner steel wire rope 222 are arranged on the side of the other shear wall panel 11, and the free end of the open stirrup 223 is connected to the free end of the corner steel wire rope 222. The free ends of the corner steel wire ropes 222 are staggered in the vertical direction, and the other ends are anchored in the shear wall panels 11. The ends of the shear wall panels 11 can also be provided with grooves sloping to both sides to facilitate subsequent grouting. During assembly, the corner reinforcement 221 is inserted into the staggered free end rope loops of the corner steel wire ropes 222 and the open stirrups 223; then, fine stone concrete is poured in the cavity formed by the two shear wall panels 11, so that the two shear wall panels 11 can transmit horizontal forces;

[0049] After the construction of one layer of building unit 1 is completed, when the construction continues upward, two shear wall panels 11 need to be vertically connected, such as Figure 3 and Figure 6 As shown, the vertical connection part 23 includes two shear wall panels 11, and a plurality of corrugated tubes 231 are uniformly pre-buried near the bottom of the shear wall panel 11. The plug interface of the corrugated tube 231 leads to the bottom of the shear wall panel 11, and the pouring port of the corrugated tube 231 extends to the side of the shear wall panel 11; the shear wall panel 11 is also pre-buried with a vertical connection rib 232 matched with the corrugated tube 231 near the top. During assembly, after the protruding end of the vertical connection rib 232 is inserted into the corrugated tube 231 of the adjacent shear wall panel 11, grouting is performed from the pouring port into the corrugated tube 231; during vertical connection, the composite plate 12 is inserted between the two adjacent wall panels to be vertically connected, and when the protruding end of the vertical connection rib 232 is inserted into the corrugated tube 231 of the adjacent shear wall panel 11, the protruding end of the vertical connection rib 232 passes through the composite plate 12, and the gap between the composite plate 12 and the shear wall panel 11 is provided with Grouting plugging material; when the two shear wall panels 11 are prefabricated, vertical steel bars are provided to ensure strength. When the two shear wall panels 11 are vertically connected, they are spliced ​​together from top to bottom. When assembled, the protruding end of the vertical connecting bar 232 is inserted into the corrugated pipe 231 of the adjacent shear wall panel 11. When the length of the vertical connecting bar 232 is not enough, the vertical connecting bar 232 can be lengthened by using a straight threaded sleeve joint. At the same time, the total cross-sectional area of ​​the vertical connecting bar 232 is greater than the total cross-sectional area of ​​the longitudinal steel bars of the reinforced concrete wall, which meets the necessity of vertical load transmission between the upper and lower layers; the bottom of the upper shear wall panel 11 is sealed with grouting plugging material around to form a closed grouting cavity at the bottom of the shear wall panel 11, and the grouting material is poured from the pouring port to fill the grouting cavity, so that the vertical connecting bar 232 and the corrugated pipe 231 connect the two shear wall panels 11 up and down under the action of the grouting material;

[0050] In summary, according to the connection structure of the shear wall panels 11, the main steps of the construction process of the vertical shear wall panels 11 are:

[0051] ① Before hoisting, check the position of the embedded vertical reinforcement 232 and the corrugated pipe 231, and extend the vertical reinforcement 232 through a straight threaded sleeve to ensure that the error is within the allowable range, and place leveling gaskets at appropriate intervals at the installation position of the shear wall panel 11 to adjust the elevation of the shear wall panel 11 from the structural surface;

[0052] ② The shear wall panel 11 is vertically positioned, the vertical connecting bars 232 extend into the corrugated tube 231, the overlapping area of ​​the flat connecting wire rope 212 is placed with the flat connecting bars 211 of this layer; the overlapping area of ​​the corner connecting wire rope 222 and the open stirrup 223 is placed with the corner connecting bars 221 of this layer;

[0053] ③ Use grouting material to seal the shear wall panel 11 to form a closed cavity at the bottom, and pour the grouting material through the grouting port of the bellows 231 after the sealing material reaches the required strength;

[0054] By utilizing the recoverable deformation property of the flat-jointed steel wire ropes 212 and the corner-jointed steel wire ropes 222, after the shear wall panel 11 is vertically dropped into place, the vertical connecting bars 232 and the longitudinal steel bars in the shear wall panel 11 are replaced with equal strength, and the interlayer longitudinal load transfer is achieved by utilizing the slurry anchor connection method; the load between the shear wall panels 11 is transferred to the flat-jointed steel wire ropes 212 and the corner-jointed steel wire ropes 222 through the bonding effect of the inserted bars and the concrete, thereby realizing the horizontal load transfer between the two shear wall panels 11.

[0055] Further, such as Figures 8 to 10As shown, a composite plate non-reinforced connection node 3 is provided between two adjacent composite plates 12; specifically, the composite plate non-reinforced connection node 3 includes an edge support node 31, an intermediate support node 32 and a close-fitting node 33, the edge support node 31 is the cooperation between the edge support and the composite plate 12, that is, the edge support node 31 is the situation when one end of the composite plate 12 cooperates with a single support (that is, a single shear wall panel 11), which is generally an external wall; the intermediate support node 32 is the cooperation between two adjacent composite plates 12 and the support, that is, the intermediate support node 32 is the situation when one end of the two composite plates 12 cooperates with a single support (that is, a single shear wall panel 11), This situation generally occurs at the cooperation between the building and the shear wall panel 11; the close-jointed node 33 is the cooperation between the two adjacent composite panels 12, that is, the close-jointed node 33 is the situation when the two composite panels 12 cooperate with each other. This situation generally occurs at the splicing of the two composite panels 12 inside the building; additional steel bars 34 are arranged at the splicing of the connection points of the composite panels 12. In order to ensure the integrity and waterproof performance of the building, the floor slab abandons the fully prefabricated floor slab and adopts the method of composite floor slab. The bottom slab is prefabricated, the composite layer is cast in place, and the composite panel has no reinforcement connection node 3. Refer to the "Technical Code for Application of Reinforced Truss Concrete Composite Slabs" T / CECS 715-2020 issued by the China Association for Engineering Construction Standardization; by adding additional steel bars 34 at the splicing positions of the side supports and the middle supports with the floor slab and the positions of the two adjacent composite panels 12, while ensuring the force transmission performance of the bottom reinforcement of the composite panel 12, the construction quality problems caused by the collision between the bottom reinforcement and the reinforcement of the support on site are avoided, and the production mold cost of prefabricated components is also reduced.

[0056] When setting up a balcony, Fig.11 and Fig.12 As shown, a balcony connection node 4 is arranged between the prefabricated balcony 13 and the adjacent shear wall panels 11 and the composite panels 12; the balcony connection node 4 includes a balcony composite panel 41 and a balcony support 42 matched with the prefabricated balcony 13, and one end of the prefabricated balcony 13 and the balcony composite panel 41 is fixed on the balcony support 42 in a stepped manner; it also includes an additional rib 43 and an additional distribution rib 44, one end of the additional rib 43 is in a hook shape and overlaps the rib of the prefabricated balcony 13, and the other end is tied with the additional distribution rib 44, and the other end of the additional distribution rib 44 is matched with the balcony composite panel 41 and tied. In this way, the balcony adopts a separated design, and the balcony ribs are split into additional ribs 43 and additional distribution ribs 44. During construction, the collision between the ribs of the balcony support 42 and the ribs of the prefabricated balcony 13 when in place can be avoided, thereby solving the problem that the prefabricated balcony 13 is difficult to be in place.

[0057] When installing stairs, Figures 13 to 17As shown, the prefabricated staircase 14 includes two, the two prefabricated staircases 14 are arranged at different heights, and a staircase connection node 5 matching the staircase is arranged in the building unit 1; the staircase connection node 5 includes a top beam 51 and a middle beam 52, and matching welded steel plates 53 are pre-embedded in the shear wall panels 11 at both ends of the top beam 51 and the middle beam 52, the top beam 51 is matched with the staircase composite plate 54 at the top of the building unit 1, and the middle beam 52 is arranged between the top and bottom of the building unit 1, one end of one of the prefabricated staircases 14 is built on the top beam 51, and the other end is built on the middle beam 52, and the other prefabricated staircase 14 is built on the top beam 51. One end of 14 is built on the middle beam 52, and the other end is built on the bottom of the building unit 1. The middle beam 52 forms a transfer platform 55 at the support of the two prefabricated stairs 14; the prefabricated stairs 14 are provided with latch holes 56 at both ends near the top beam 51 and the middle beam 52, and the top beam 51 and the middle beam 52 are fixed with stair dowels 57 that match the latch holes 56. During assembly, the stair dowels 57 are inserted into the latch holes 56; in this way, by pre-embedding the welded steel plate 53 in the shear wall panel 11 that matches the prefabricated stair 14, the top beam 51 and the middle beam 52 are connected to the pre-embedded welded steel plate 53 by welding. One end of the prefabricated staircase 14 is placed on the top beam 51, and the other end is placed on the middle beam 52. The contact position is leveled with cement mortar in advance; the stair dowel bars 57 welded on the top beam 51 and the middle beam 52 are respectively inserted into the pin holes 56 provided at both ends of the prefabricated staircase 14, and finally grouting material is injected into the pin holes 56 to complete the connection between the prefabricated staircase 14 and the top beam 51 and the middle beam 52; the gaps between the prefabricated staircase 14 and the top beam 51 and the middle beam 52 are filled with filling materials, and after placing the PE rod 6, the modified silicon series sealant is evenly applied. Angle steel is also welded on the side of the top beam 51 to form a staggered platform for the top beam 51, with one end used as a support for the prefabricated staircase 14 and the other end as a support for the composite plate.
