Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated buildings, and in particular to a construction method of a beam-column connector and a wall. Background Art

[0002] The prefabricated interior walls in rail transit stations are relatively high, with some areas exceeding 6m in height. Wall panels usually use lightweight wall panels such as ALC panels with a single wall panel length of 3m, a thickness of 0.1m-0.2m, and a width of 0.5m-0.6m. In order to enhance the overall stability of the wall, it is necessary to set up structural columns and ring beams. Structural columns and ring beams are usually prefabricated. Connecting steel bars are reserved at the ends of the prefabricated ring beams and prefabricated structural columns. When the ring beams are connected to the structural columns, local cast-in-situ is carried out at the connection nodes. Therefore, there are currently a lot of on-site wet operations in the construction and construction of large walls. Since multiple ring beams and structural columns are connected and fixed at the nodes, the connecting steel bars in multiple directions are prone to occupying each other, which is not convenient for welding and fixing, and it is difficult to accurately position them when connecting. The space at the connection node is small and cast-in-situ is difficult. During construction, the structural columns require a large number of temporary fixed supports. The overall cast-in-situ fixation will not be carried out until the wall panels are installed, resulting in disadvantages such as a long construction period. Since the structures of the ring beams and ground beams are similar, the main difference is that the corresponding settings are different, so the structural columns and ground beams also have the above problems. Summary of the Invention

[0003] The purpose of the invention is to provide a beam-column connector, through which the structural column and the ring beam are connected to each other, thereby avoiding the mutual occupation of the connecting steel bars of the structural column and the ring beam, thereby enabling the structural column and the ring beam to be accurately positioned during installation, and increasing the space of the connection node, thereby facilitating connection and fixation.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is:

[0005] A beam-column connector includes an upper connecting plate and a lower connecting plate, wherein a side connecting plate is connected between the upper connecting plate and the lower connecting plate, wherein the upper connecting plate and the lower connecting plate are both provided with at least two through holes 1, and the side connecting plate is provided with at least two through holes 2, wherein the through holes 1 are used to fix the connecting steel bars of the structural column, and the through holes 2 are used to fix the connecting steel bars of the ring beam or the ground beam.

[0006] After the connecting steel bars of the structural column are passed through at least two of the first through holes of the upper connecting plate or the lower connecting plate, the beam-column connecting piece can constrain the structural column to form a preliminary connection, thereby facilitating the fixing of the beam-column connecting piece to the structural column by conventional fixing measures such as welding at the construction site. Similarly, the beam-column connecting piece can also be connected and fixed to the ring beam through the second through hole;

[0007] The upper connecting plate and the lower connecting plate can both be fixedly connected to the structural column. According to the positional relationship between the structural column and the ring beam in the wall, the side connecting plate is set on different sides of the beam-column connecting piece according to the specific working conditions, and then adaptively connected and fixed with the ring beam. Through the cooperation of multiple beam-column connecting pieces, all the structural columns and ring beams in the wall can be connected and fixed to each other, and the beam-column connecting piece is a three-dimensional structural piece with a certain internal space that can be used for fixing operations. Compared with the previous cross-welding of connecting steel bars in multiple directions, it can have a larger node space. Similarly, the beam-column connecting piece is also suitable for the connection and fixation of structural columns and ground beams to achieve the corresponding effect.

[0008] The present invention provides a beam-column connector, in which the structural column and the ring beam are connected to each other through the beam-column connector, so the connecting steel bars of the ring beam and the structural column do not need to be cross-welded to each other, thereby avoiding the situation where the end steel bars of the structural column and the ring beam occupy each other's position, thereby enabling the structural column and the ring beam to be accurately positioned during the installation process, and increasing the space of the connection node, making it easier for workers to connect and fix.

[0009] Preferably, a distance is provided between the side connecting plate and the through hole, and the distance is used to form a space for fixing operation.

[0010] Through the designed spacing, the connecting steel bars between the ring beam and the structural column do not need to be staggered, and can also adapt to the working condition where the connecting steel bars are too long. It has stronger on-site compatibility and can effectively reduce the phenomenon of mutual occupation. Workers can use the space formed by the interval to fix the connecting steel bars passing through the second through hole, that is, a space is formed for fixing operations on the inner wall of the beam-column connector.

[0011] Preferably, there are two side connecting plates, the upper connecting plate and the lower connecting plate are "L"-shaped plates, and the two side connecting plates are respectively located at two end surfaces of the "L"-shaped plate.

[0012] The upper connecting plate, the lower connecting plate and the side connecting plates are combined to form an "L"-shaped structural member, and the two side connecting plates serve as the two end faces of the "L"-shaped structural member. The beam-column connecting member can connect and fix two mutually perpendicular ring beams, and is suitable for working conditions where the beam-column connecting member is located at the connection of two mutually perpendicular walls, such as the corner of a wall.

[0013] Preferably, there are three side connecting plates, the upper connecting plate and the lower connecting plate are "T"-shaped plates, and the three side connecting plates are respectively located on the three end surfaces of the "T"-shaped plate.

[0014] The upper connecting plate, the lower connecting plate and the side connecting plate are combined to form a "T"-shaped structural member, and the three side connecting plates serve as the two end faces of the "T"-shaped structural member. The beam-column connecting member can connect and fix three ring beams, which is suitable for working conditions where the beam-column connecting member is located at the connection of three wall surfaces.

[0015] Preferably, two side connecting plates are provided, the upper connecting plate and the lower connecting plate are rectangular plates, and the two side connecting plates are located at two opposite end surfaces of the rectangular plate.

[0016] The upper connecting plate, the lower connecting plate and the side connecting plates are combined to form a rectangular structural member, and the two side connecting plates are parallel to each other. The beam-column connecting member can connect and fix two collinear ring beams, which is suitable for working conditions where the beam-column connecting member is located within a single wall surface. Since the two side connecting plates are located on two opposite sides of the rectangular structural member, the other two opposite sides of the rectangular structural member are vacant and can be used as space for fixed operations. Therefore, the side connecting plates and the through hole 1 do not need to be set to form a spacing for fixed operation space.

[0017] Preferably, the upper connecting plate is provided with four through holes 1, and the lower connecting plate is also provided with four through holes 1, and the positions of the through holes 1 are adapted to the connecting steel bars of the structural column.

[0018] The upper connecting plate and the lower connecting plate are provided with four through holes, which can effectively match the existing structural column structure and facilitate the connection and fixation of the structural column. The existing structural column is usually prefabricated with four connecting steel bars, and the four connecting steel bars are evenly distributed at the four corners of the structural column.

[0019] Preferably, the side connecting plate has four through holes 2, and the opening positions of the multiple through holes 2 can adapt to the connecting steel bars of the ring beam or the ground beam; or the side connecting plate has two through holes 2, and the horizontal heights of the two through holes 2 are the same.

[0020] The side connecting plate is provided with four through holes 2, which can effectively match the existing ring beam structure or ground beam structure, and is convenient for the connection and fixation of the ring beam or ground beam. The existing ring beam or ground beam is also usually prefabricated with four connecting steel bars, and the four connecting steel bars are evenly distributed at the four corners of the structural column; according to the different positions of the beam-column connector in the wall, the side connecting plate may not need to be connected to the ring beam or ground beam. For example, the beam-column connector can also be used for the connection and fixation of the structural column and the upper floor slab. The beam-column connector can also be fixed to the floor slab through expansion bolts or post-anchor bars, so that the beam-column connector can also realize the connection and fixation of the entire wall skeleton. The side connecting plate only has two through holes 2, which can change the height of the beam-column connector, so that the height of the entire wall can be flexibly fine-tuned, which is beneficial to the installation and leveling of the wall.

[0021] Preferably, a vertical transverse partition is connected between the upper connecting plate and the lower connecting plate, and the transverse partition is vertically connected to the side connecting plate.

[0022] The transverse partition strengthens the structural strength of the beam-column connection, and the vertical arrangement of the transverse partition enhances the bearing capacity of the beam-column connection. The transverse partition and the side connecting plate are perpendicular to each other to avoid the formation of excessively long connecting steel bars extending into the through hole one or the through hole two.

[0023] Preferably, the transverse partition is provided with a third through hole, and the third through hole is used to provide an operating space.

[0024] The aperture of the through hole three can be designed specifically according to the working conditions, and the mass of the beam-column connection can be reduced while ensuring the structural strength. The through hole three is used to provide an operating space for fixing the connecting steel bars on one side of the diaphragm to the other side, such as by welding. The aperture of the through hole three can be convenient for welding construction, that is, the welding tool welds the connecting steel bars on the other side of the diaphragm on one side, thereby avoiding the obstruction of the wall or ring beam and making it difficult to perform the fixing operation on the other side of the diaphragm. In addition, the through hole three also facilitates the later pouring and filling of the beam-column connection with ALC concrete.

[0025] Preferably, the plate surface of the side connecting plate is smaller than the cross section of the ring beam or the ground beam.

[0026] Since rail transit specifications do not allow exposed steel structures in walls, the side connecting plate is designed so that the sides of the beam-column connectors do not protrude from the sides of the ring beam or ground beam, making it easier to fill and wrap the exposed beam-column connectors with concrete at a later stage, complying with rail transit specifications and not hindering the installation of prefabricated wall panels.

[0027] Preferably, the beam-column connector is a steel structural member.

[0028] The materials for steel structural parts are easy to obtain, have good structural strength, and have good welding performance with connecting steel bars.

[0029] A wall construction method, using the beam-column connector as described above to construct the wall, comprises the following steps:

[0030] A: Use beam-column connectors to connect the structural columns and ring beams to form the wall skeleton and fix them to the floor slab;

[0031] B: Assemble and fix the wall panels in sequence within the wall frame, use mortar to fill the beam-column connectors, and complete the wall construction.

[0032] The wall construction method of the present invention can first install and fix the structural columns and ring beams to form a wall skeleton and then fill in the prefabricated wall panels. The beam-column connectors have good connection performance. The structural columns are connected and fixed by the beam-column connectors, which has better stability than the existing method of fixing by connecting steel bars through welding. Therefore, the temporary fixed supports required for the structural columns can be greatly reduced during the wall construction process. The use of the beam-column connectors effectively reduces the amount of cast-in-place construction, avoids the problem of the connecting steel bars of the structural columns and the ring beam occupying each other, and is conducive to increasing the construction speed, shortening the construction period, and saving construction costs.

[0033] Preferably, in step A, threaded grooves are provided at the ends of the connecting steel bars of the ring beam and the structural column, and the threaded grooves are used for installing nuts.

[0034] After threading the ends of the connecting steel bars between the ring beam and the structural column and passing them through the through holes of the beam-column connector, they can be fastened to the beam-column connector with nuts, eliminating the need to weld the connecting steel bars to the beam-column connector. The operation is simple, the construction conditions are low, and the on-site operability is strong.

[0035] Preferably, in step B, sequentially assembling and fixing the wall panels in the wall frame includes the following steps:

[0036] B1: Assemble the wall panels from the bottom layer of the wall frame upwards. Remove the rib structure in advance in the area of the wall panel corresponding to the ring beam connection surface. Then, place the wall panels in other areas into the wall frame from this area and push them horizontally to the corresponding area. Finally, assemble the wall panels in this area to complete the bottom layer of wall panel assembly.

[0037] B2: Complete the assembly of the wall panels of the remaining layers in sequence according to the assembly method of the bottom layer.

[0038] In prefabricated walls, prefabricated wall panels and ring beams are usually connected by grooves and ribs on the connecting surface. Here, the connecting surface of the ring beam needs to be designed as a rib structure, and the connecting surface of the wall panel is a groove structure. By partially smoothing the rib structure on the connecting surface of the ring beam, the wall panel can be easily placed into the wall frame in the area where the rib structure is removed, and the entire layer of wall panels can be connected and assembled by horizontal pushing, which greatly simplifies the assembly construction of the wall panels and has strong on-site operability.

[0039] Preferably, in step B1, for the area where the rib structure of the ring beam is removed, the corresponding wall panels are reduced in size so that a gap for filling mortar is formed between the wall panels and the ring beam or floor slab.

[0040] Since the wall panel corresponding to the area where the rib structure is removed is the last wall panel assembled on the entire floor, there is no corresponding operating space to use pipe clamps to fix the wall panel. If the length of the wall panel is not adjusted, the connection gap between the wall panel and the ring beam or floor slab is very small, making it difficult to implement some fixing measures. By reducing the size of the wall panel, a certain gap is created between the wall panel and the ring beam or floor slab, which is convenient for bonding and fixing with cement mortar, thereby simplifying the fixing operation of the wall panel and improving on-site operability.

[0041] Preferably, a local notch is opened at the connecting end of the wall panel to reduce the size, and the wall panel is fixed to the ring beam or floor slab through pipe clamps; or the overall length of the wall panel is reduced to reduce the size, and the wall panel is fixed to the beam-column connector or structural column through bent pipe clamps.

[0042] There are many ways to reduce the size of the wall panels to fill the gaps. The overall length of the wall panels can be shortened during prefabrication to provide space for filling with cement mortar during assembly. At the same time, the connection stability of the wall panels can be further enhanced by bending pipe clamps. Local gaps can be opened in the connecting sections of the wall panels to provide bonding space for cement mortar during assembly, and conventional pipe clamps can be used for further connection and reinforcement.

[0043] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0044] 1. A beam-column connector of the present invention connects the structural column and the ring beam to each other through the beam-column connector, so the connecting steel bars of the ring beam and the structural column do not need to be cross-welded, thereby avoiding the situation where the end steel bars of the structural column and the ring beam occupy each other's position, thereby enabling the structural column and the ring beam to be accurately positioned during installation, and increasing the space of the connection node, making it easier for workers to connect and fix. Similarly, the beam-column connector is also suitable for connecting the structural column and the ground beam;

[0045] 2. Through the specific shape design of the beam-column connector, it can be effectively applied to different locations of the wall to connect the structural column and the ring beam. The "T"-shaped beam-column connector is suitable for the nodes of three walls, the "L"-shaped beam-column connector is suitable for the nodes of the wall corners, and the rectangular beam-column connector is suitable for the nodes inside a single wall. Various forms of beam-column connectors enable the structural column and the ring beam to be accurately positioned during the installation process, and the structural connection does not require cast-in-place, which is convenient and fast in construction. Similarly, various forms of beam-column connectors are also suitable for the connection of structural columns and ground beams.

[0046] 3. The number and position design of the second through-holes on the side connecting plate make it easy to flexibly fine-tune the height of the entire wall when the beam-column connector is applied to the top layer of the wall, which is beneficial for the installation and leveling of the wall;

[0047] 4. Through the design of the diaphragm and the three through holes, the diaphragm can strengthen the structural strength of the beam-column connection. It is also convenient for fixing the connecting steel bars on one side of the diaphragm to the other side, and is conducive to the subsequent pouring and filling of concrete on the beam-column connection.

[0048] 5. A wall construction method of the present invention can first install and fix the structural columns and ring beams to form a wall skeleton and then fill in the prefabricated wall panels. The beam-column connectors have good connection performance. The structural columns are connected and fixed by the beam-column connectors, which has better stability than the existing method of fixing by welding connecting steel bars. Therefore, the temporary fixed supports required for the structural columns can be greatly reduced during the wall construction process. The use of the beam-column connectors effectively reduces the amount of cast-in-place construction and avoids the problem of the connecting steel bars of the structural columns and the ring beam occupying each other's space, which is conducive to increasing the construction speed, shortening the construction period, and saving construction costs.

[0049] 6. By partially smoothing the rib structure at the ring beam connection surface and reducing the size of the corresponding wall panels, the wall panels can be easily placed into the wall frame in the area where the rib structure is removed. The entire layer of wall panels can be snapped together and assembled by pushing horizontally. A certain gap is left between the assembled wall panels and the ring beam or floor slab, making it easier to bond and fix them with cement mortar. This greatly simplifies the wall panel assembly construction and improves on-site operability.

[0050] 7. By threading the ends of the connecting steel bars of the ring beam, ground beam and structural column, they can be passed through the through holes of the beam-column connectors and then fastened to the beam-column connectors with nuts. This eliminates the need to weld the connecting steel bars to the beam-column connectors. The operation is simple, the construction conditions are low, and the on-site operability is strong.

DETAILED DESCRIPTION

[0066] The present invention will be described in detail below with reference to the accompanying drawings.

[0067] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0068] Example 1

[0069] like Figure 1 、 Figure 4 and Figure 7 As shown, a beam-column connector of the present invention includes an upper connecting plate 1 and a lower connecting plate 2, a side connecting plate 3 is connected between the upper connecting plate 1 and the lower connecting plate 2, the upper connecting plate 1 and the lower connecting plate 2 are each provided with at least two through holes 1 4, the side connecting plate 3 is provided with at least two through holes 2 5, the through holes 1 4 are used to fix the connecting steel bars 10 of the structural column 8, and the through holes 2 5 are used to fix the connecting steel bars 10 of the ring beam 9 or the ground beam 17.

[0070] In this embodiment, the beam-column connector is a steel structural member. Since the structural column 8, ground beam 17 and ring beam 9 are usually provided with four embedded steel bars during prefabrication, there are also four corresponding connecting steel bars 10 extending out of the end face, and the four connecting steel bars 10 are usually located at the four corners of the end face of the structural column 8, ground beam 17 or ring beam 9, and serve as the four vertices of the rectangle. The upper connecting plate 1 of the beam-column connector is correspondingly provided with four through holes 4, and the four through holes 4 are mutually adapted with the four connecting steel bars 10 of the structural column 8, that is, the four connecting steel bars 10 of the structural column 8 can be inserted into the four through holes 4 without obvious shaking in the through holes 4; the lower connecting plate 2 is also provided with four through holes 4, and the through holes 4 of the lower connecting plate 2 are vertically corresponding to the through holes 4 of the upper connecting plate 1, and the lower connecting plate 2 can also be adapted and connected with the structural column 8, and the shape and size of the upper connecting plate 1 and the lower connecting plate 2 are also consistent.

[0071] When the beam-column connector needs to connect the ring beam 9 or the ground beam 17 , the side connecting plate 3 is provided with four through holes 2 5 . Similarly, the four through holes 2 5 are adapted to the four connecting steel bars 10 of the ring beam 9 or the ground beam 17 .

[0072] Furthermore, when the beam-column connectors are connected at different positions of the wall, the number and relative positions of the side connecting plates 3 will be adaptively changed;

[0073] like Figure 1-Figure 3As shown, when the beam-column connector is used at the connection of three wall surfaces, the beam-column connector may simultaneously connect two structural columns 8 and three ring beams 9. The beam-column connector is correspondingly provided with three side connecting plates 3. In order to facilitate workers to fix the connecting steel bars 10 of the ring beam 9, each side connecting plate 3 has a certain distance from the through hole 1 4, so that the beam-column connector forms an operating space for the through hole 2 5. That is, the upper connecting plate 1 and the lower connecting plate 2 are both designed as "T"-shaped steel plates. The upper connecting plate 1 and the lower connecting plate 2 cooperate with the side connecting plates 3 to form a "T"-shaped structural member, and the three side connecting plates 3 correspond to the three end faces of the "T"-shaped structural member.

[0074] like Figure 4-Figure 6 As shown, when the beam-column connector is used at the connection between two wall surfaces, such as the corner of a wall, the beam-column connector may need to connect two mutually perpendicular ring beams 9. The beam-column connector is correspondingly provided with two side connecting plates 3. The upper connecting plate 1 and the lower connecting plate 2 are both designed as "L"-shaped steel plates. The upper connecting plate 1 and the lower connecting plate 2 cooperate with the side connecting plates 3 to form an "L"-shaped structural member. The two side connecting plates 3 correspond to the two end faces of the "L"-shaped structural member, so that there is a certain distance between the side connecting plates 3 and the through hole 1 4. Workers use this spacing to facilitate the fixing of the connecting steel bars 10 passing through the through hole 2 5.

[0075] like Figure 7 and Figure 8 As shown, when the beam-column connector is used in a single wall surface, the beam-column connector may also need to connect two collinear ring beams 9. The beam-column connector is correspondingly provided with two side connecting plates 3. The upper connecting plate 1 and the lower connecting plate 2 are both designed as rectangular steel plates. The upper connecting plate 1 and the lower connecting plate 2 cooperate with the side connecting plates 3 to form a rectangular structural member. The two side connecting plates 3 serve as two opposite sides of the rectangular structural member, and the two side connecting plates 3 are parallel to each other.

[0076] When the beam-column connector is used to connect the structural column 8 and the floor slab at the top of the wall, the beam-column connector may not need to connect the ring beam 9. On the basis of the rectangular, "L"-shaped or "T"-shaped structural member, the side connecting plate 3 can correspondingly only be provided with two through holes 5 of the same horizontal height, leaving the operating space required for fixing the structural column 8 connecting the steel bar 10, and the two through holes 5 can be used to fix the bent pipe clamp 12 during construction, such as Figure 9 As shown, the adaptability deformation of the beam-column connection is made based on the rectangular structure.

[0077] Furthermore, a vertical transverse partition 6 is connected between the upper connecting plate 1 and the lower connecting plate 2. Each side connecting plate 3 is connected to a corresponding transverse partition 6. The side connecting plates 3 and the transverse partitions 6 connected thereto are perpendicular to each other and are located at the midline position corresponding to the four through holes 2 5.

[0078] A through hole 3 7 is further provided in the middle of each diaphragm 6. The aperture of the through hole 3 7 can be designed to be larger according to the working conditions, which can reduce the mass of the beam-column connection parts and facilitate the welding of the welding tool on one side of the diaphragm 6 to the connecting steel bars 10 on the other side. That is, the welding tool passes through the through hole 3 7 for welding, thereby avoiding the obstruction of the wall or the ring beam 9 and making it difficult to perform the fixing operation on the other side of the diaphragm 6. In addition, the design of the through hole 3 7 also facilitates the subsequent pouring and filling of the beam-column connection parts with ALC concrete.

[0079] The size of the through hole 1 4 and the through hole 2 5 can be just adapted to the cross section of the corresponding connecting steel bar 10, or can be slightly larger than the cross section of the connecting steel bar 10 to facilitate the plug-in operation during construction, as long as the four through holes can interact with each other to constrain the four connecting steel bars 10 from shaking too much;

[0080] Since rail transit specifications do not allow exposed steel structures in walls, the surface of the side connecting plate 3 is designed to be slightly smaller than the cross-section of the ring beam 9 or the ground beam 17, that is, the surface of the side connecting plate 3 will not protrude from the side of the ring beam 9 or the ground beam 17, which makes it easier to fill and wrap the exposed beam-column connectors with concrete in the later stage, complies with the requirements of relevant specifications, and will not affect the installation of the prefabricated wall panels 16.

[0081] In addition, the specific technical solution of this embodiment is based on the fact that the ring beam 9, the ground beam 17 and the structural column 8 are all pre-embedded with four embedded steel bars, so the corresponding connecting plates are provided with the same number of through holes, that is, the number and position of the through holes of the connecting plate are determined based on the prefabricated ring beam 9, the ground beam 17 or the structural column 8.

[0082] Example 2

[0083] A wall construction method of the present invention uses the beam-column connector described in Example 1 to construct the wall, comprising the following steps:

[0084] A: Use beam-column connectors to connect the structural columns 8 and ring beams 9 to form a wall skeleton and fix them to the floor slab;

[0085] B: Assemble and fix the wall panels 16 in sequence within the wall frame, fill the beam-column connectors with mortar, and complete the wall construction.

[0086] In this embodiment, if Figure 10 As shown, the object of construction is a single-sided wall. The wall skeleton is formed by four structural columns 8, a ring beam 9 and a ground beam 17. The wall skeleton is divided into a bottom layer and a top layer. Each layer in the wall skeleton is filled with five prefabricated wall panels 16 that are assembled horizontally. The ring beam 9 and the wall panels 16 are clamped and fixed by a groove and rib structure, and the connecting surface of the ring beam 9 is provided with a rib, and the connecting surface of the wall panel 16 is provided with a groove.

[0087] In step A, the upper floor 14 and the lower floor 15 are fixed with connecting steel plates 13 at the positions corresponding to the connection of the structural columns 8. Figure 11 As shown, the connecting steel plate 13 is a connector with four steel bars perpendicular to the plate surface. The four steel bars of the connecting steel plate 13 can be inserted into the four through holes 4 of the upper connecting plate 1 and can be fixed by welding, or threaded grooves are opened at the ends of the four steel bars of the connecting steel plate 13, and nuts are used to fix the connecting steel plate 13 to the beam-column connector.

[0088] There is a beam-column connector at each end of each structural column 8. The structural column 8 of the bottom layer is fixed to the lower floor 15 through the beam-column connector at the bottom end, and the structural column 8 of the top layer is fixed to the upper floor 14 through the beam-column connector at the top end. The structural columns 8 corresponding vertically to the bottom and top layers are also connected together through the beam-column connector. The top end of the bottom structural column 8 is horizontally connected to the ring beam 9, and the bottom end of the bottom structural column 8 is horizontally connected to the ground beam 17. The ring beam 9 and the ground beam 17 are also fixedly connected to the structural column 8 through the beam-column connector to complete the construction of the wall skeleton; wherein, the connecting steel bars 10 of the ring beam 9 or the ground beam 17 and the structural column 8 are correspondingly inserted into the through holes 5 of the side connecting plate 3, and can be fixed by welding, or a threaded groove can be opened at the end of the connecting steel bar 10, and the ring beam 9 and the ground beam 17 are fixed to the beam-column connector and the structural column 8 respectively using nuts.

[0089] Furthermore, the beam-column connectors can also be connected to the structural columns and floor slabs through expansion bolts or post-installed anchor bars, thereby achieving the connection and fixation between the wall frame and the main structure.

[0090] In addition, since the beam-column connector between the structural column 8 and the upper floor slab 14 does not need to be horizontally connected to the ring beam 9, a beam-column connector with only two through holes 25 in the side connecting plate 3 can be selected, and the horizontal height of the two through holes 25 is the same. In this way, the height of the beam-column connector can be changed, so that the height of the entire wall can be flexibly fine-tuned. For example, the height of the beam-column connector with four through holes 25 in the side connecting plate 3 is usually 200 mm, and the height of the beam-column connector with two through holes 25 in the side connecting plate 3 can be as low as 100 mm. Therefore, during construction, the height of the wall can be effectively adjusted within the range of 0 to 100 mm, which is beneficial to the installation and leveling of the wall.

[0091] In step B, to ensure the stability of the wall frame, the wall panels 16 must be assembled from the bottom up first, that is, the wall panels 16 of the lower layer must be assembled before the wall panels 16 of the upper layer can be assembled;

[0092] This time, all the wall panels 16 of the bottom layer are assembled before assembling the wall panels 16 of the top layer. When prefabricating the ring beam 9, the ribs are removed from the portion of the connection surface of the ring beam 9 corresponding to the rightmost wall panel 16. The ring beam 9 is also the ring beam 9 that is transversely connected to the top structural column 8. When prefabricating the wall panels 16, the wall panels 16 corresponding to the rightmost side of the wall are correspondingly reduced in length, so that a sufficient gap is formed between the wall panels 16 on the rightmost side of the wall and the ring beam 9, thereby facilitating the operation of filling mortar. In addition, the connection surface of the wall panels 16 can also be free of grooves.

[0093] The area where the ribs are eliminated in the ring beam 9, the wall panels 16 at other positions of the wall (the wall panels 16 that have not been reduced in size) can be placed directly in the wall frame. During assembly, the wall panel 16 on the far left of the wall is first placed directly in the area on the far right of the bottom layer, and then the wall panel 16 is pushed horizontally to the left side of the ring beam 9. When pushed horizontally, the groove at the top of the wall panel 16 on the far left of the wall can be engaged with the ribs of the ring beam 9. Similarly, the wall panels 16 at other positions are assembled in sequence until the wall panel 16 on the far right of the bottom layer is placed in and fixed by the pipe clamps 11. Before assembly, each wall panel 16 is first nailed into the pipe clamps 11 at the upper and lower end faces of the wall panel 16, about 100 mm away from the right side. After each wall panel 16 is pushed to the predetermined area, the pipe clamps 11 are connected to the ring beam 9 or the ground beam 17 with nails to complete the fixation of each wall panel 16. Figure 12 As shown, the pipe clamp 11 is a connecting piece with a cylindrical column fixed on a single flat plate; after the five wall panels 16 fill the bottom layer, the five wall panels 16 on the top layer can be assembled with reference to the wall panels 16 on the bottom layer. The only difference is that the upper end of the wall panel 16 is fixedly connected to the upper floor slab 14, and the connection surface of the ring beam 9 without the rib corresponds to the lower end of the wall panel 16.

[0094] The size of the rightmost wall panel 16 of the wall can be reduced by shortening the entire length of the wall panel 16 or by designing a local notch at the connecting end of the wall panel 16, such as Figure 13 As shown, for example, a rectangular notch is provided at the top of the wall panel 16 to form an L-shaped end;

[0095] If the wall panel 16 on the far right of the wall is designed to be shortened in overall length, and the overall length of the wall panel 16 is reduced by 100 mm, a gap of 100 mm is formed between the wall panel 16 and the ring beam 9, and the top end of the wall panel 16 is connected and fixed to the beam-column connector by the bent pipe clamp 12, as shown in FIG. Figure 14 As shown, the bent pipe clamp 12 is a conventional pipe clamp 11 with a bent section added to the flat end thereof, thereby facilitating the fixing of the wall panel 16 to the beam-column connector or the structural column 8;

[0096] If the rightmost wall panel 16 of the wall body is a rectangular notch designed in the top section, the gap between the wall panel 16 and the ring beam 9 is the size of the corresponding notch, and the top end of the wall panel 16 can be connected and fixed to the ring beam 9 through an ordinary pipe clamp 11.

[0097] After the wall panels 16 are assembled, ALC mortar is used to fill the gaps between the rightmost wall panel 16 and the ring beam 9 and the floor slab. The gaps in all beam-column connectors are also filled with ALC mortar, and the outer surfaces of all beam-column connectors are also coated with a layer of ALC mortar to wrap them so that the surfaces of the beam-column connectors remain flat with the surface of the ring beam 9 or the ground beam 17.

[0098] In addition, the ring beam 9 can also choose to cancel the rib setting corresponding to the part of any segment wall panel 16, and the installation of the entire wall panel 16 can be completed. For example, the ring beam 9 connection surface corresponding to the middle wall panel 16 is selected. After canceling the ribs of the ring beam 9, the wall panels 16 in the remaining positions can be pushed horizontally from the middle to both sides and inserted into the wall frame. Finally, the wall panel 16 with reduced size is installed in the middle position to complete the installation of the wall panel 16 of this layer of the wall frame.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
