Description

[0002] For a side wall shear wall component of a garbage pool such as a garbage incineration power station, the interlayer height is large, and usually needs to be poured in layers. For the formwork support of a middle section shear wall, due to the lack of support of horizontal structural components, according to the traditional method, the horizontal bars of the outer landing scaffold (operation frame) are extended to the wall side to support the weight of the formwork and the main and secondary keels. This method is prone to cause the stress overload of the outer landing scaffold, thereby increasing the risk of collapse and lateral overturning. In addition, for the middle section shear wall, the lateral support frame is difficult to set up, and the lower end of the support rod is usually fixed in two ways. One is to be fixed on the outer landing scaffold vertical rod by rotating fasteners, which further increases the risk of lateral overturning of the outer landing scaffold. The other method is to set a pre-embedded part in the lower wall to install the lower support tripod. When the pouring height is large, since the angle of the inclined support is usually less than 60°, the length of the cantilever beam is required to be large. Taking a pouring height of 3.5 meters as an example, the length of the upper beam body of the tripod will reach 2 meters, and the lateral stability is not easy to guarantee, and the work load of installing and dismounting the support frame is large.

[0062] In the embodiment, the first shear wall 1 can be understood as a shear wall structure at the bottom of the entire shear wall structure

[0063] The force wall region, that is, the low section shear wall, the second shear wall can be understood as the shear wall region of the middle section of the whole shear wall structure, that is, the middle section shear wall. Specifically, the whole shear wall structure needs to be poured and built in sections during the manufacturing process. The stage at which the support structure shown in the embodiment is adapted is when the first shear wall 1 has been poured and the second shear wall has not yet been poured, that is, the pouring and manufacturing stage of the middle section shear wall.

[0064] Further, during the manufacturing process of the second shear wall, a formwork assembly 2 needs to be prepared, which includes a first formwork 21 and a second formwork 22. The structure and material of the first formwork 21 and the second formwork 22 can be completely the same, the difference being that the first formwork 21 corresponds to one side of the second shear wall, and the second formwork 22 corresponds to the other side of the second shear wall. In use, the first formwork 21 and the second formwork 22 are placed on the upper mounting area 8 of the first shear wall 1. It should be noted that after pouring, the first shear wall 1 is placed in the mounting area 8 for ease of description. Specifically, the lower part of the first formwork 21 has a first connecting section, and the lower part of the second formwork 22 has a second connecting section. The first connecting section and the second connecting section are oppositely arranged in the mounting area 8, that is, the first connecting section is the part of the first formwork 21 placed in the mounting area 8 of the first shear wall 1, and the second connecting section is the part of the second formwork 22 placed in the mounting area 8 of the first shear wall 1. Further, the first connecting section is attached to one side of the outer surface of the first shear wall 1, and the second connecting section is attached to the other side of the outer surface of the first shear wall 1. The first connecting section and the second connecting section can provide a fixed basis for the space structure of the first formwork 21 and the second formwork 22, so that the first formwork 21 and the second formwork 22 can be parallel to each other, and the pouring cavity formed by the first formwork 21 and the second formwork 22 is consistent in shape with the first shear wall 1, that is, the second shear wall formed after subsequent pouring of concrete is consistent in size with the first shear wall 1, thereby improving the overall consistency of the first shear wall 1 and the second shear wall.

[0065] Further, the first support assembly 3 is arranged in the mounting area 8, which includes a first cross beam 31 and a second cross beam 32. The first cross beam 31 supports the first formwork 21, and the second cross beam 32 supports the second formwork 22. The first cross beam 31 is arranged at the lower edge of the first connecting section, and can be stably connected to the mounting area 8 in the form of a first embedded bolt 41 described later, while bearing the entire weight of the first formwork 21. Similarly, the second cross beam 32 is arranged at the lower edge of the second connecting section, and can be stably connected to the mounting area 8 in the form of a first embedded bolt 41 described later, while bearing the entire weight of the second formwork 22. Optionally, the first cross beam 31 and the second cross beam 32 can be placed at the same height and oppositely arranged on both sides of the first shear wall 1.

[0066] Specifically, the embodiment further includes a first embedded component 4, the first embedded component 4 includes a first embedded bolt 41 and a second embedded bolt 42, the first embedded bolt 41 penetrates the installation area 8 of the first shear wall 1 to connect the first cross beam 31 and the second cross beam 32, that is, during the pouring process of the first shear wall 1, the first embedded bolt 41 is placed in the pouring area of the first shear wall 1 in advance, then after pouring and setting of the concrete, the first embedded bolt 41 is embedded in the installation area 8, on this basis, the first cross beam 31 and the second cross beam 32 are installed and locked by the corresponding nut, which can realize the fixation of the first cross beam 31 and the second cross beam 32 on the first shear wall 1. Similarly, the second embedded bolt 42 can be placed in the installation area 8 in the same embedding manner as the first embedded bolt 41. The second embedded bolt 42 penetrates the installation area 8 of the first shear wall 1 and connects the first connecting section and the second connecting section. The first embedded bolt 41 and the second embedded bolt 42 adopt a three-section conical water stop bolt.

[0067] In the embodiment, the first formwork 21 and the second formwork 22 refer to the formwork in construction, and the materials generally include steel formwork, aluminum alloy formwork, plywood, plastic formwork, etc. The main function of the formwork is to serve as a mold shell and support for concrete pouring and forming, to maintain the position, size and geometric shape required by the design, to bear the self-weight of the formwork and external loads thereon, and to ensure the forming of the concrete structure. The fixing mode of the formwork has a direct impact on the construction efficiency, cost and concrete pouring effect.

[0068] On this basis, the embodiment further includes a second support component 5, the second support component 5 includes a third cross beam 51, a fourth cross beam 52, a first longitudinal beam 53 and a second longitudinal beam 54, wherein the third cross beam 51 and the first longitudinal beam 53 are used to fix the first formwork 21, the fourth cross beam 52 and the second longitudinal beam 54 are used to fix the second formwork 22, the third cross beam 51 and the first longitudinal beam 53 are cross-distributed on the outer surface of the first formwork 21, further, the third cross beam 51 and the first longitudinal beam 53 are fixed by the second embedded component 6, the fourth cross beam 52 and the second longitudinal beam 54 are cross-distributed on the outer surface of the second formwork 22, further, the fourth cross beam 52 and the second longitudinal beam 54 are fixed by the second embedded component 6. In this process, the cross points of the third cross beam 51 and the first longitudinal beam 53 and the cross points of the fourth cross beam 52 and the second longitudinal beam 54 can be arranged on the same reference line, so that one embedded bolt can be used to connect the cross points on both sides, saving the production cost and process, while fully guaranteeing the consistency of the structural distribution between the first formwork 21 and the second formwork 22.

[0069] Further, the second pre-embedded component 6 comprises a third pre-embedded bolt 61 and a fourth pre-embedded bolt 62. The third pre-embedded bolt 61 is arranged in the pouring cavity where the second shear wall is located. Specifically, the two ends of the third pre-embedded bolt 61 protrude out of the first formwork 21 and the second formwork 22, respectively. The part of the third pre-embedded bolt 61 protruding out of the first formwork 21 can hold the third cross beam 51 together with a nut, and the part of the third pre-embedded bolt 61 protruding out of the second formwork 22 can hold the fourth cross beam 52 together with a nut. In this way, the relative fixation of the third cross beam 51 and the fourth cross beam 52 can be achieved. It can be understood that the cross point of the first longitudinal beam 53 and the third cross beam 51 can be arranged at the fixed position of the third pre-embedded bolt 61, and the cross point of the second longitudinal beam 54 and the fourth cross beam 52 can be arranged at the fixed position of the third pre-embedded bolt 61. In this way, the specific fixation operation of the second support component 5 can be further saved. Correspondingly, the size of the third pre-embedded bolt 61 is adjusted and selected according to the shear force borne thereon. The third pre-embedded bolt 61 is a three-section conical water stop bolt, and the fourth pre-embedded bolt 62 is a three-section conical water stop bolt. The fourth pre-embedded bolt 62 can be understood as a pre-embedded bolt connecting the third cross beam 51 and the fourth cross beam 52. The fourth pre-embedded bolt 62 and the third pre-embedded bolt 61 can use the same structure and model, which is not limited in the embodiment. It should be noted that the arrangement of the fourth pre-embedded bolt 62 can strengthen the connection between the third cross beam 51 and the fourth cross beam 52, thereby enhancing the overall stability and bearing capacity between the first formwork 21 and the second formwork 22.

[0070] In the embodiment, the first cross beam 31, the second cross beam 32, the third cross beam 51, and the fourth cross beam 52 refer to horizontal members connecting longitudinal beams (vertical supports). The main function is to provide stability and bearing capacity in the horizontal direction for the formwork frame, to constitute a fixed frame structure of the formwork assembly 2, and to enhance the rigidity and bearing capacity of the entire formwork assembly 2. The first longitudinal beam 53 and the second longitudinal beam 54 refer to main bearing beams arranged in the longitudinal direction of the building structure, which transmit the load to the support system.

[0071] In this embodiment, the middle placement assembly 7 includes a core-filled steel pipe 71, a first hook bolt 72, and a second hook bolt 73. The core-filled steel pipe 71 is a steel pipe for pouring concrete in the middle. Further, the core-filled steel pipe 71 is divided into a first support section 712 and a first embedded section 711. The first embedded section 711 is inserted into the pouring area of the first shear wall 1 in advance when the first shear wall 1 is poured. After the concrete in the first shear wall 1 solidifies, the first embedded section 711 is formed to be embedded in the installation area 8. The first support section 712 is arranged in the pouring chamber and is used to support the part of the first formwork 21 and the second formwork 22 for pouring the second shear wall. It can be understood that the core-filled steel pipe 71 remains in the vertical direction and serves as the main support structure of the first formwork 21 and the second formwork 22. The core-filled steel pipe 71 is connected perpendicularly to the first shear wall 1. A plurality of connection nodes for fixing the first formwork 21 and the second formwork 22 can be arranged on the first support section 712, such as the socket disc 74 described below. The first support section 712 is connected to the first cross beam 51 through the first hook bolt 72 and is connected to the fourth cross beam 52 through the second hook bolt 73. It should be noted that the number of core-filled steel pipes 71 can be multiple, and the number of first hook bolts 72 and second hook bolts 73 can also be multiple. The number of first hook bolts 72 and second hook bolts 73 can be set according to actual needs. The first hook bolt 72 and the second hook bolt 73 adopt a single-side cone water stop bolt.

[0072] This embodiment includes the formwork assembly 2, the first support assembly 3, the second support assembly 5, the first embedded assembly 4, the second embedded assembly 6, and the middle placement assembly 7. The middle placement assembly 7 solves the problem of vertical support and lateral stability in the existing formwork system, especially when the height of the formwork assembly 2 is large. The lateral support scheme is more difficult to implement. In this embodiment, the core-filled steel pipe 71 in the middle placement assembly 7 is pre-filled to form a steel pipe concrete structure, which greatly enhances the stiffness of the core-filled steel pipe 71 itself. After the current support structure and concrete pouring are completed, the position of the second shear wall does not need to be supplemented with grouting, which improves the efficiency of on-site construction. In the case where there is no horizontal structural member to provide support in the support structure of the second shear wall, the core-filled steel pipe 71 can be embedded. For the construction of the side wall at the floor, the traditional construction process of the outer inclined bracing structure can still be used for construction. The scheme selection is flexible. The first embedded bolt 41 and the first support assembly 3 are used to support the formwork assembly 2, which can bear the self-weight of the first formwork 21, the second formwork 22, and the second support assembly 5. The on-site construction operation is convenient, and the force transmission path is simple. The first hook bolt 72 and the second hook bolt 73 are used to pull together, which can realize reliable force transmission, improve efficiency, and improve economy.

[0073] Please refer to Figure 1 and Figure 2In some embodiments, the first support assembly 3 further comprises a fifth cross beam 33 and a sixth cross beam 34. The fifth cross beam 33 is arranged at the first connecting section, and the second embedded bolt 42 is connected to the first connecting section through the fifth cross beam 33; the sixth cross beam 34 is arranged at the second connecting section, and the second embedded bolt 42 is connected to the second connecting section through the sixth cross beam 34; the first embedded assembly 4 further comprises a first fastener 43 and a second fastener 44. The first fastener 43 is fastened at the connection between the fifth cross beam 33 and the second embedded bolt 42; and the second fastener 44 is fastened at the connection between the sixth cross beam 34 and the second embedded bolt 42.

[0074] In the present embodiment, the fifth cross beam 33 is arranged on the outer surface of the first connecting section, and the sixth cross beam 34 is arranged on the outer surface of the second connecting section. Optionally, the fifth cross beam 33 and the sixth cross beam 34 are arranged at the same height, and the two ends of the second embedded bolt 42 can be connected to the fifth cross beam 33 and the sixth cross beam 34, respectively. Specifically, the first embedded assembly 4 further comprises the first fastener 43 and the second fastener 44, and the specific shape of the first fastener 43 and the second fastener 44 can be set according to actual needs. For example, in the present embodiment, the number of the fifth cross beams 33 is two and they are arranged side by side, and the first fastener 43 corresponds to a 3-type fastener or a C-type fastener. The second embedded bolt 42 is arranged between the two fifth cross beams 33 and is bolted to the first fastener 43 to fix the two fifth cross beams 33 and the first connecting section in the installation area 8. Similarly, the number of the sixth cross beams 34 is also two and they are arranged side by side, and the second fastener 44 corresponds to a 3-type fastener or a C-type fastener. The second embedded bolt 42 is arranged between the two sixth cross beams 34 and is bolted to the second fastener 44 to fix the two sixth cross beams 34 and the second connecting section in the installation area 8.

[0075] In the present embodiment, by arranging the first fastener 43, the second fastener 44, the fifth cross beam 33 and the sixth cross beam 34, the stable connection between the first formwork 21 and the installation area 8 of the first shear wall 1, and the stable connection between the second formwork 22 and the installation area 8 of the first shear wall 1 are achieved.

[0076] Please refer to Figure 1 and Figure 2 In some embodiments, the non-inclined support shear wall support structure of the middle filling core steel pipe 71, part of the first longitudinal beam 53 and the fifth cross beam 33 are arranged in cross, and the first longitudinal beam 53 and the first cross beam 31 are overlapped; part of the second longitudinal beam 54 and the sixth cross beam 34 are arranged in cross, and the second longitudinal beam 54 and the second cross beam 32 are overlapped.

[0077] In the embodiment, a part of the first longitudinal beam 53 is hung down to the mounting area 8 and crosses the fifth cross beam 33, and further, the lower end of the first longitudinal beam 53 is overlapped on the first cross beam 31, so that the first cross beam 31 can bear the gravity of the first longitudinal beam 53, the third cross beam 51 and the first formwork 21. Similarly, a part of the second longitudinal beam 54 is hung down to the mounting area 8 and crosses the sixth cross beam 34, and further, the lower end of the second longitudinal beam 54 is overlapped on the second cross beam 32, so that the second cross beam 32 can bear the gravity of the second longitudinal beam 54, the fourth cross beam 52 and the second formwork 22.

[0078] The structure shown in the embodiment can increase the connection stability of the first longitudinal beam 53 and the second longitudinal beam 54, and further strengthen the connection tightness of the first formwork 21 and the second formwork 22 with the mounting area 8.

[0079] Please refer to Figure 1 and Figure 2 In some embodiments, the third cross beam 51 extends in the horizontal direction, and the fourth cross beam 52 is symmetrically arranged with the third cross beam 51; the first longitudinal beam 53 extends in the vertical direction, and the second longitudinal beam 54 is symmetrically arranged with the first longitudinal beam 53.

[0080] The embodiment shows that the extending direction of the third cross beam 51 and the fourth cross beam 52 is the horizontal direction, and the extending direction of the first longitudinal beam 53 and the second longitudinal beam 54 is the vertical direction, so that the orthogonal layout is adapted to the existing construction method, and the construction of the first formwork 21 and the second formwork 22 is more convenient. The setting position of the third embedded bolt 61 can save the laying of the redundant bolts on site, and improve the utilization rate of the third embedded bolt 61.

[0081] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments, the second embedded component 6 further comprises a third fastener 63 and a fourth fastener 64. The third fastener 63 is fastened at the connection between the fourth embedded bolt 62 and the third cross beam 51; and the fourth fastener 64 is fastened at the connection between the fourth embedded bolt 62 and the fourth cross beam 52.

[0082] In the embodiment, the use of the third fastener 63 and the fourth fastener 64 can improve the overall stability and safety of the structure. Similar to the first fastener 43 and the second fastener 44, the specific structure of the third fastener 63 and the fourth fastener 64 can be set according to actual needs, which is not limited in the embodiment. In the embodiment, the connection of the plurality of structural components is more stable by setting the third fastener 63 and the fourth fastener 64, which reduces the risk of structural instability caused by improper construction or load changes, and improves the construction efficiency and quality, prevents relative sliding or loosening of the connection part under stress, and enhances the rigidity and carrying capacity of the structure.

[0083] Please refer to Figure 1 、 Figure 2 and Figure 3 In some embodiments, the intermediate assembly 7 further comprises a set of socket plates 74. The set of socket plates 74 comprises a plurality of socket plates 74, which are spaced apart along the vertical direction on the first support section 712. Each socket plate 74 is provided with a first connecting hole 741 and a second connecting hole 742, which are oppositely arranged. The first hook head bolt 72 is connected to the first support section 712 through the first connecting hole 741, and the second hook head bolt 73 is connected to the first support section 712 through the second connecting hole 742.

[0084] In this embodiment, the first hook head bolt 72 and the core filling steel pipe 71 are connected to the first connecting hole 741, and the second hook head bolt 73 and the core filling steel pipe 71 are connected to the second connecting hole 742. The socket plate 74 is sleeved on the periphery of the core filling steel pipe 71. In this embodiment, the plurality of socket plates 74 can be spaced apart along the axial direction of the core filling steel pipe 71 by welding. It should be noted that the first hook head bolt 72 and the second hook head bolt 73 correspond to one socket plate 74. When the number of socket plates 74 is more than one, the number of first hook head bolts 72 and second hook head bolts 73 corresponds to the number of socket plates 74. Optionally, in some embodiments, if the height of the socket plate 74 is exactly the cross point of the first longitudinal beam 53 and the third transverse beam 51, and is also the cross point of the second longitudinal beam 54 and the fourth transverse beam 52, the first hook head bolt 72 and the second hook head bolt 73 can replace the third embedded bolt 61 that is supposed to be arranged at this position, achieving the same supporting effect and reducing the production cost. In this embodiment, the plurality of socket plates 74 are arranged to make the connection between the core filling steel pipe 71 and the first formwork 21 and the second formwork 22 more stable, simple in structure and high in safety factor.

[0085] Please refer to Figure 1 and Figure 2 In some embodiments, the length of the first embedded section 711 is not less than 500 mm. This length can improve the anchoring effect of the core filling steel pipe 71 in the first shear wall 1, increase the strength of the first support section 712, and improve the construction safety.

[0086] Please refer to Figure 1 and Figure 2 In some embodiments, the first transverse beam 31 and / or the second transverse beam 32 is made of a square steel pipe.

[0087] In some embodiments, using square steel tubes as the first cross beam 31 and / or the second cross beam 32 can provide higher stability and load-bearing capacity. Square steel tubes have good torsional resistance and symmetrical cross-sectional properties due to their structural characteristics, which makes the load distribution more uniform when under load, reducing the risk of structural damage caused by local stress concentration. In addition, square steel tubes are also easy to process and install, which helps to improve construction efficiency. Square steel tubes can provide better mechanical properties when under load due to their cross-sectional properties. The moment of inertia of a square cross-section is more uniform in all directions than other shapes, which helps to maintain the stability of the structure in complex stress situations. At the same time, the four corners of the square steel tube provide additional support points, which can better resist shear force and bending moment, thereby improving the stiffness and strength of the entire support structure. Square steel tube refers to a tube with a square cross-section made of steel, with four equal sides and four right angles. Square steel tubes are often used in building structures that require high stability and load-bearing capacity due to their structural symmetry and uniform cross-sectional properties.

[0088] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments, the number of first embedded components 4 is multiple, and the multiple first embedded components 4 are distributed along the horizontal direction; the number of third cross beams 51 is multiple, and the multiple third cross beams 51 are distributed along the vertical direction on the first formwork 21; the number of fourth cross beams 52 is multiple, and the multiple fourth cross beams 52 are distributed along the vertical direction on the second formwork 22; the number of first longitudinal beams 53 is multiple, and the multiple first longitudinal beams 53 are distributed along the horizontal direction on the first formwork 21; the number of second longitudinal beams 54 is multiple, and the multiple second longitudinal beams 54 are distributed along the horizontal direction on the second formwork 22; the number of middle components 7 is multiple, and the multiple middle components 7 are distributed along the horizontal direction.

[0089] Further, according to the above scheme, the following examples can be developed:

[0090] A non-inclined bracing shear wall formwork system using a middle core filling steel tube 71, including a core filling A core disc buckle steel tube, a hook bolt and a hook bolt for connecting the formwork and the middle steel tube, a socket disc 74 welded on the side wall of the built-in steel tube, a wall-penetrating counter-bolt, a vertical back brace of the shear wall formwork, a horizontal brace, a type buckle, a bottom hanging formwork, a bottom hanging formwork, a bottom embedded wall-penetrating counter-bolt, and a bottom horizontal brace.

[0091] After the lower segment of the shear wall is poured and the formwork is removed, the pre-buried wall-penetrating tension bolts at the bottom are reserved, the bottom cross-beam is fixed, and the formwork of the middle segment of the shear wall is hung down by one segment, that is, the bottom hanging formwork and the bottom hanging formwork in the figure are placed on the upper part of the bottom cross-beam. The bottom cross-beam is generally made of square wood or square steel pipe to abut against the poured lower segment of the shear wall. At the same time, the vertical cross-beam is also extended downward by a certain length and locked by the tension bolts to reduce the risk of bottom leakage and misalignment of the poured shear wall. The self-weight of the upper shear wall formwork and the back-beam is borne by the bottom cross-beam.

[0092] Before pouring the lower segment of the shear wall, the disc buckle steel pipe treated by the shrinkage-compensating concrete is pre-buried on the upper part of the lower segment of the shear wall, the pre-buried depth is not less than 500mm, the verticality is adjusted, and the hook head bolt is installed after positioning. The hook head bolt is arranged at the position of the wall-penetrating tension bolt. Then, after the reinforcement binding of the middle segment of the shear wall is completed, the position of the tension bolt hole is determined, the formwork of the shear wall is holed, the installation of the formwork of the shear wall and the back-beam is completed, and finally the hook head bolts on both sides are fastened to ensure that the formwork of the shear wall and the internal steel pipe bear force together.

[0093] By adopting the technical scheme, the present application has the beneficial effects compared with the prior art:

[0094] Different from the prior art, the above technical scheme comprises a formwork assembly 2, a first support assembly 3, a second support assembly 5, a first pre-buried assembly 4, a second pre-buried assembly 6 and a middle assembly 7. The middle assembly 7 solves the problem of vertical support and lateral stability in the existing formwork system, especially when the height of the formwork assembly 2 is large, the lateral support scheme is more difficult to adopt. The pre-coring of the core steel pipe 71 in the middle assembly 7 forms a steel pipe concrete structure, greatly enhancing the rigidity of the core steel pipe 71 itself. After the current support structure and the concrete pouring are completed, the position of the second shear wall can no longer be supplemented with grouting, improving the efficiency of on-site construction. In the case that there is no horizontal structural member to provide support in the support structure of the second shear wall, the core steel pipe 71 can be pre-buried. For the side wall construction at the floor, the traditional side wall construction process can still be used for construction with the outside diagonal bracing structure, and the scheme selection is flexible. The first pre-buried bolt 41 and the first support assembly 3 are used to support the formwork assembly 2, which can bear the self-weight of the first formwork 21, the second formwork 22 and the second support assembly 5, and the on-site construction operation is convenient, and the force transmission path is simple. The first hook head bolt 72 and the second hook head bolt 73 are used to connect, which can realize reliable force transmission, improve efficiency and improve economy.

[0095] The above merely describes some embodiments of the present application, and is not intended to limit the protection scope of the present application, and any equivalent device or equivalent process transformation, or direct or indirect application in other related technical fields, which are made by using the content of the present application specification and drawings, are also included in the patent protection scope of the present application.
