Description

Technical Field

[0002] Double-headed steel joists are an important component used in building support frames, especially in socket-type disc-type steel pipe support frame systems. The main function of this joist is to increase the distance between the vertical poles, thereby reducing the amount of support frame materials used, while ensuring the overall safety and stability of the support frame.

[0003] For non-vertical beams, such as T-beams, the angle of the template needs to be adjusted according to the inclination angle of the beam to ensure that the support frame can adapt to the inclination of the beam.

[0038] The technical solution of the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] The components of the embodiments of the present application generally described and shown in the accompanying drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the application claimed, but merely represents the selected embodiments of the present application.

[0040] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of this application.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0042] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0043] like Figure 1 As shown, the present invention proposes a double-headed steel joist replacing the bottom upright of the beam, comprising at least two columns 1, a joist 2 fixedly installed between the two columns 1, a supporting component installed on the joist 2, a template 104 installed on the supporting component and the columns 1, the columns 1 are connected to the ground, the joist 2 is supported by the columns 1, and the template 104 is supported by the joist 2 and the columns, and concrete 9 can be poured on the template 104.

[0044] In this embodiment, Figure 1 , Figure 2A second tray 102 is fixedly mounted on the column 1, and a second support column 103 is movably mounted in the second tray 102. The second support column 103 can directly contact the template 104 and support the template 104, which can effectively increase the support area of ​​the template 104 and improve the stability of the support of the template 104. A plurality of reinforcing rods 106 are detachably mounted on the first plate buckle 105, and the reinforcing rods 106 are detachably connected to adjacent first plate buckles 105. Adjacent columns 1 are connected to each other through the reinforcing rods 106, which can improve the integrity of the overall structure and thus improve the stability of the structure.

[0045] See also Fig.11 The third plate buckle 101 is fixedly installed on the column 1, and the joist 2 includes two double-channel steels 201. A second connecting pipe 202 is detachably installed between the two double-channel steels 201. A second bolt 203 is threadedly connected to the second connecting pipe 202. The two double-channel steels 201 can be fixedly connected through the threaded connection of the second connecting pipe 202 and the second bolt 203, so that the two double-channel steels 201 can form a joist 2, and the joist 2 can be supported by the third plate buckle 101. The supporting component includes a plurality of supporting plates 301 movably installed on the two double-channel steels 201. The supporting plates 301 abut against the joist 2 under the action of gravity, and the supporting component can be supported by the joist 2. The support disk 301 is fixedly mounted with a support cylinder 3, and the support cylinder 3 is internally threaded with a height adjustment rod 302, and the third tray 303 is rotatably mounted on the height adjustment rod 302, and the third support column 304 is movably mounted on the third tray 303. The third support column 304 can support the template 104 by supporting and contacting the third support column 304 with the template 104, and the height adjustment rod 302 can be rotated to lift and lower the height adjustment rod 302, thereby driving the third tray 303 to lift and lower, and then adjusting the height of the third tray 303, thereby ensuring that the third support column 304 effectively supports the template 104. A limit assembly for limiting the support cylinder 3 is detachably mounted on the support cylinder 3. Since the support disk 301 is abutted against the joist 2, when the support cylinder 3 is subjected to lateral force, the support cylinder 3 is prone to slippage, thereby causing the problem of unstable support effect.

[0046] Among them Fig.12 , Fig.13The limiting assembly includes a connecting head 4 detachably mounted on the supporting plate 301, a connecting block 401 is rotatably mounted on the connecting head 4, a limiting rod 402 is fixedly mounted on the connecting block 401, a fourth sealing head 403 is fixedly mounted on the limiting rod 402, a fourth positioning cylinder 404 is slidably mounted on the fourth sealing head 403, both ends of the fourth positioning cylinder 404 are connected through a fourth pipe 405, a second valve 406 is fixedly mounted on the fourth pipe 405, the fourth positioning cylinder 404, the fourth pipe 405 and the second valve 406 are all filled with hydraulic medium, a connecting plate 407 is fixedly mounted on the other end of the fourth positioning cylinder 404, two clamping blocks 408 are rotatably mounted on the connecting plate 407, and connecting columns 409 are threadedly connected to the two clamping blocks 408. When installing the limit assembly, first fix the connector 4 to the support plate 301, sleeve the two clamping blocks 408 on the second connecting tube 202, and fix the two clamping blocks 408 through the connecting column 409, and then the limit assembly can be installed between the support plate 301 and the second connecting tube 202.

[0047] Furthermore, due to the setting of the fourth sealing head 403, the space inside the fourth positioning cylinder 404 is divided into two parts. When the second valve 406 is closed, the hydraulic medium in the two parts of the space inside the fourth positioning cylinder 404 will not be able to circulate with each other. At this time, when the fourth sealing head 403 moves inside the fourth positioning cylinder 404, it is necessary to squeeze the hydraulic medium inside the fourth positioning cylinder 404, and the hydraulic medium is a fluid that is not easily compressed, such as hydraulic oil. This will cause the fourth sealing head 403 to be unable to move under working conditions, and thus the limit rod 402 cannot move, and thus the total length of the limit rod 402 and the fourth positioning cylinder 404 cannot change. When the support cylinder 3 slips, it will inevitably drive the limit rod 402 to move, and the limit rod 402 will not be able to move when the second valve 406 is closed. Then, the opening and closing of the second valve 406 can be controlled to control whether the position of the support cylinder 3 is fixed, thereby effectively preventing the entire support component from slipping, thereby ensuring the stability of the device in supporting the template 104.

[0048] like Figure 1The double-headed steel support beam of this embodiment also includes a side support component, which is installed on the column 1. The side support component includes a bracket installed on the column 1, a support part rotatably installed on the column 1 to support the template 104, an angle adjustment mechanism installed on the bracket to control the angle of the support part, and an auxiliary support assembly installed on the bracket to fix the support part. Since when pouring the beam body, it is necessary not only to support the bottom of the beam body through the template 104, but also to support the side of the beam body through the template 104, it is necessary to set a side support component to support the template 104 on the side of the beam body. For T-shaped beams, the side templates of the beam body are inclined, which requires an angle adjustment mechanism to adjust the angle of the template 104 to ensure that the template 104 is parallel to the side of the beam body, so that the template 104 can effectively support the beam body. Since the template 104 is built on the steel support beam, it is difficult to finely and accurately adjust the angle of the template 104, which will increase the difficulty of construction and cause problems such as extended construction period.

[0049] Further Figure 1 , Figure 3 In the embodiment, the first buckle 105 and the second buckle 107 are fixedly mounted on the column 1, and the support portion includes a first connecting pipe 5 detachably mounted on the first buckle 105 and the second buckle 107, and the first connecting pipe 5 is threadedly connected with a first bolt 501. The first connecting pipe 5 is passed through the first buckle 105 and the second buckle 107, and the first bolt 501 is threadedly connected to the first connecting pipe 5, so that the first connecting pipe can be fixed on the first buckle 105 and the second buckle 107, and before installing the first connecting pipe 5, the support block 502 is placed between the first connecting tube 5 passing through the first disc buckle 105 and the second disc buckle 107. The first connecting tube 5 passes through the support block 502, and the support block 502 can be fixedly installed between the first disc buckle 105 and the second disc buckle 107. In order to prevent the first connecting tube 5 from rotating on the first disc buckle 105 and the second disc buckle 107, the connection between the first connecting tube 5 and the first disc buckle 105 and the second disc buckle 107 can be set to a polygon. Similarly, the connection between the first connecting tube 5 and the support block 502 can also be set to a polygon.

[0050] Please review Figure 3 , Figure 4In the embodiment, a sleeve 503 is fixedly mounted on the support block 502, a distance adjusting rod 504 is connected to the sleeve 503 through an internal thread, a support plate 505 is rotatably mounted on the distance adjusting rod 504, a guide rod 506 is fixedly mounted on the support plate 505, and the guide rod 506 is slidably connected to the sleeve 503. The distance adjusting rod 504 can be moved inside the sleeve 503 by rotating the distance adjusting rod 504, thereby adjusting the total length of the sleeve 503 and the distance adjusting rod 504. A base plate 507 is rotatably mounted on the support plate 505, a plurality of first trays 508 are fixedly mounted on the base plate 507, and a plurality of first support columns 509 are detachably mounted on the first tray 508. The template 104 can be supported by the first support columns 509, so that the first support columns 509 can evenly contact the template on the side of the beam body, thereby effectively improving the support stability of the template 104 on the side of the beam body. A positioning assembly is installed in the first tray 508 to fix the first support column 509 according to the gravity of the first support column 509. Since the installation position of the first support column 509 is inclined and close to vertical, the first support column 509 is easy to slide off the first tray 508 when installing it, which is easy to cause harm to the construction workers, and the construction is difficult and takes a long time.

[0051] Among them Figure 6 As shown, the positioning assembly includes two steel bars 6 fixedly installed on both sides of the first pallet 508, a support shaft 601 is fixedly installed between the two steel bars 6 located on both sides of the first pallet 508 and symmetrical to each other, a driving sleeve 602 is slidably installed on the two support shafts 601, and two connecting grooves 603 are provided on the driving sleeve 602. The connecting grooves 603 correspond to the support shafts 601 one by one and are slidably connected. The driving sleeve 602 is limited and guided by the two connecting grooves 603, so that the driving sleeve 602 can only rotate around its axis. Two cylinders 604 are fixedly installed in the first tray 508, and a guide sleeve 605 is fixedly installed on the two cylinders 604. A plurality of displacement rods 606 are slidably installed on the guide sleeve 605, and a first positioning block 607 is fixedly installed on the displacement rod 606. A connecting rod 608 is rotatably installed on the other end of the displacement rod 606, and the other end of the connecting rod 608 is rotatably connected to the driving sleeve 602. A push rod 609 for supporting the first support column 509 is slidably installed on the guide sleeve 605. When installing the first support column 509, it is necessary to place the first support column 509 inside the guide sleeve 605. At this time, the first support column 509 entering the guide sleeve 605 will squeeze the push rod 609 and drive the push rod 609 to move.

[0052] The first tray 508 is provided with a transmission assembly that drives the driving sleeve 602 to rotate according to the position of the push rod 609. Under the action of the transmission assembly, when the push rod 609 moves, the driving sleeve 602 will be driven to rotate, and the rotating driving sleeve 602 will drive the multiple connecting rods 608 to rotate, and the rotating connecting rods 608 will push the displacement rod 606 to move, and the moving displacement rod 606 will drive the first positioning block 607 to move in the direction close to the first support column 509. By setting multiple first positioning blocks 607, and multiple first positioning blocks 607 are located around the first support column 509, the first positioning blocks 607 can effectively support the first support column 509 to prevent the first support column 509 from slipping, which can effectively improve the safety during construction.

[0053] Further, Fig. 9 As shown, the transmission assembly includes a first sealing head 610 fixedly mounted on the top rod 609, a first positioning cylinder 611 fixedly mounted in the first tray 508, the first sealing head 610 is slidably connected to the first positioning cylinder 611, a second positioning cylinder 612 is rotatably mounted on the first tray 508, a second sealing head 613 is slidably mounted in the second positioning cylinder 612, a driving rod 614 is fixedly mounted on the second sealing head 613, the driving rod 614 passes through one end of the second positioning cylinder 612 and is rotatably connected to the driving sleeve 602, first pipes 615 are fixedly mounted at both ends of the first positioning cylinder 611 and the second positioning cylinder 612, the first positioning cylinder 611 and the second positioning cylinder 612 are connected at both ends through the first pipe 615, and the first positioning cylinder 611, the second positioning cylinder 612 and the first pipe 615 are filled with hydraulic medium. When the push rod 609 moves downward, it will drive the first sealing head 610 to move. The moving first sealing head 610 will press the hydraulic medium inside the first positioning cylinder 611 into the second positioning cylinder 612, and the hydraulic medium entering the second positioning cylinder 612 will push the second sealing head 613 to move, thereby driving the driving rod 614 to move to the outside of the first positioning cylinder 611, thereby changing the assembly degree of the first positioning cylinder 611 and the driving rod 614, thereby making the first positioning cylinder 611 rotate on the first tray 508, and making the driving rod 614 rotate on the driving sleeve 602 while driving the driving sleeve 602 to rotate. Fig.10 .

[0054] It is worth noting that Fig. 9 In the embodiment, the driving sleeve 602 is provided with a notch 616, and the cylinder 604 and the first positioning cylinder 611 are both located inside the notch 616. By setting the notch 616, the cylinder 604 and the first positioning cylinder 611 will not interfere with the rotation of the driving sleeve 602 when the driving sleeve 602 rotates.

[0055] In this embodiment, Figure 5 As shown, the inclination adjustment mechanism includes an arc sleeve 7 fixedly mounted on the support plate 505, an arc plate 701 fixedly mounted on the first tray 508, the center of the arc sleeve 7 and the arc plate 701 coincides with the rotation connection axis of the first tray 508 and the support plate 505, a sealing block 702 is fixedly mounted on the arc plate 701, a receiving barrel 703 is fixedly mounted on the support plate 505, the receiving barrel 703 is connected to the arc sleeve 7 through a second pipe 704, a sealing plate 705 is slidably mounted in the receiving barrel 703, an adjusting rod 706 is threadedly connected to the receiving barrel 703, and a rotating shaft on the adjusting rod 706 is provided. A second positioning block 707 is installed, and the arc plate 701 and the receiving barrel 703 are filled with hydraulic medium. When the angle of the first support column 509 is adjusted, it is necessary to rotate the base plate 507 to drive the first tray 508 to rotate, and then drive the first support column 509 to rotate, so that the plane formed by the sides of multiple first support columns 509 can be parallel to the surface of the template 104. When the base plate 507 rotates, it will drive the arc plate 701 to rotate inside the arc sleeve 7. Under the sealing action of the sealing block 702, the hydraulic oil inside the arc sleeve 7 will be pressed into the receiving barrel 703.

[0056] Figure 7 It can be seen that a transparent strip 708 is fixedly mounted on the containing barrel 703 , and a scale strip 709 is provided on one side of the containing barrel 703 and located on the transparent strip 708 . The second positioning block 707 can be driven to move by rotating the adjusting rod 706, and the position of the second positioning block 707 will limit the highest position of the sealing plate 705, and then the effective volume inside the containing barrel 703 can be adjusted by rotating the adjusting rod 706, and the hydraulic medium entering the containing barrel 703 through the second pipe 704 will squeeze the sealing plate 705, so that the sealing plate 705 moves upward, and when the sealing plate 705 abuts the second positioning block 707, the sealing plate 705 will not be able to move, and the arc plate 701 cannot rotate inside the arc sleeve 7, so that the rotation angle of the base plate 507 can be limited, and the liquid level position of the hydraulic medium can be observed through the transparent strip 708, and the rotation angle of the base plate 507 can be accurately controlled and limited in combination with the scale bar 709, which can effectively reduce the construction difficulty and improve the construction efficiency, and is suitable for the construction of non-vertical beam formwork 104.

[0057] Among them Figure 8As shown, the auxiliary support assembly includes a third positioning cylinder 8 rotatably mounted on the support plate 505, a third sealing head 801 is slidably mounted in the third positioning cylinder 8, a long rod 802 is fixedly mounted on the third sealing head 801, the long rod 802 penetrates one side of the third positioning cylinder 8 and extends to the outside of the third positioning cylinder 8, the other end of the long rod 802 is rotatably connected to the support plate 505, the two ends of the third positioning cylinder 8 are connected through a third pipe 803, a first valve 804 is fixedly mounted on the third pipe 803, and the third positioning cylinder 8, the third pipe 803 and the first valve 804 are all filled with hydraulic medium. Referring to the principle introduction of the limit assembly, it can be obtained by the same logic that when the angle of the substrate 507 is adjusted, the position of the substrate 507 needs to be fixed. At this time, the angle of the substrate 507 can be fixed by simply closing the first valve 804. When the angle of the substrate 507 is adjusted again, the first valve 804 needs to be opened and the position of the second positioning block 707 is adjusted again.

When the base plate 507 rotates, it will drive the arc plate 701 to rotate inside the arc sleeve 7. Under the sealing action of the sealing block 702, the hydraulic oil inside the arc sleeve 7 will be pressed into the inside of the containing barrel 703.

[0066] The second positioning block 707 can be driven to move by rotating the adjusting rod 706, and the position of the second positioning block 707 will limit the highest position of the sealing plate 705, and then the effective volume inside the containing barrel 703 can be adjusted by rotating the adjusting rod 706, and the hydraulic medium entering the containing barrel 703 through the second pipe 704 will squeeze the sealing plate 705, so that the sealing plate 705 moves upward, and when the sealing plate 705 abuts the second positioning block 707, the sealing plate 705 will not be able to move, and the arc plate 701 cannot rotate inside the arc sleeve 7, so that the rotation angle of the base plate 507 can be limited, and the liquid level position of the hydraulic medium can be observed through the transparent strip 708, and the rotation angle of the base plate 507 can be accurately controlled and limited in combination with the scale bar 709, which can effectively reduce the construction difficulty and improve the construction efficiency, and is suitable for the construction of non-vertical beam formwork 104.
