Description

Technical Field

[0001] The present application relates to the field of building construction, and in particular to a multi-layer combined temporary support structure of a door frame and a buckle frame. Background Art

[0002] In the process of bridge construction, such as temporary bridge deck construction, main beam and support construction, cable tower construction and other stages, disc-type scaffolding is usually used for temporary support construction.

[0003] The use of disc-type scaffolding for temporary support construction can achieve three-dimensional construction area in a short time, improve the utilization rate of construction personnel and equipment, and thus improve the overall construction efficiency. Moreover, since the disc-type scaffolding can be used multiple times, it can effectively reduce the cost caused by material loss during the construction process.

[0004] Regarding the above-mentioned related technologies, although the disc-type frame is convenient for quickly realizing the temporary erection of the supporting structure to facilitate the construction of the bridge, when constructing some larger bridge decks, the disc-type frame usually also needs to occupy a large ground space for overall erection, the space utilization rate is low and the continuous flatness requirements of the ground are high, which is not convenient for adapting to different terrains. Utility Model Content

[0005] In order to improve the space utilization of the temporary support structure and adapt to different terrains, the present application provides a multi-layer combined temporary support structure of a door frame and a disc buckle frame.

[0006] The present application provides a multi-layer combined temporary support structure of a door frame and a disc buckle frame, which adopts the following technical solution:

[0007] A multi-layer combined temporary support structure of a gantry and a disc-hook frame comprises a gantry and a disc-hook frame, wherein the gantry comprises columns and Bailey beams arranged on the tops of the columns, wherein the columns are provided in two groups, and the two groups of columns are respectively close to both sides of the length direction of the Bailey beam; the disc-hook frame comprises a vertical unit and a horizontal unit, wherein a plurality of connecting I-beams distributed along the length direction of the Bailey beam are installed on the top of the Bailey beam, and the horizontal unit is arranged on the top of the Bailey beam and connected to the connecting I-beams through a connecting assembly, and the vertical units are provided in two groups and are respectively connected to both sides of the length direction of the horizontal unit, and the gantry is located between the two groups of vertical units.

[0008] By adopting the above technical scheme, the temporary support structure composed of the door frame and the disc-hook frame does not need to occupy a large ground space for overall erection compared to the temporary support structure directly erected by the disc-hook frame, which is beneficial to improve the space utilization rate after the temporary support structure is erected. At the same time, the uneven ground between the two groups of columns will not affect the erection of the overall temporary support structure, thereby facilitating adaptation to different terrains and having strong applicability. In addition, the Bailey beam achieves further stable support for the horizontal unit by connecting the I-beam, which is beneficial to fully ensure the overall stability of the temporary support structure.

[0009] Optionally, the horizontal unit includes vertical rods, and a plurality of groups of the vertical rods are arranged in a one-to-one correspondence with the connecting I-beams, and each group of the vertical rods has several vertical rods distributed along the length direction of the connecting I-beams. The connecting components are arranged in a one-to-one correspondence with the vertical rods, and the connecting components include a connecting block, a connecting screw and a fixing plate. The connecting block is installed at the bottom of the vertical rod, and the connecting block is provided with a sliding groove. The connecting I-beam is slidably fitted in the sliding groove, the connecting screw is penetrated and threadedly fitted in the connecting block, and the fixing plate is fixedly installed on one end of the connecting screw close to the connecting I-beam, and the fixing plate is located in the sliding groove.

[0010] By adopting the above technical solution, when the connecting screw is rotated, the connecting screw cooperates with the thread of the connecting block to drive the fixing plate to move towards or away from the connecting I-beam. When the fixing plate is pressed against the connecting I-beam, a firm fixation between the vertical rod and the connecting I-beam is achieved. When there is a gap between the fixing plate and the connecting I-beam, the fixation between the vertical rod and the connecting I-beam is released. The fixing or loosening of the vertical rod and the connecting I-beam can be achieved by rotating the connecting screw, and the operation is convenient and fast.

[0011] Optionally, a positioning screw is threadedly matched with the top of the connecting block, and one end of the positioning screw extends into the sliding groove.

[0012] By adopting the above technical solution, the setting of the positioning screw makes it easier for personnel to achieve initial fixation between the connecting block and the connecting I-beam, and then facilitates the subsequent firm fixation between the connecting block and the connecting I-beam by screwing the connecting screw.

[0013] Optionally, two groups of the connecting screws and the fixing plates are provided and are respectively located on both sides of the width direction of the connecting I-beam, and a rotating handle is fixedly connected to one end of each connecting screw away from the connecting I-beam.

[0014] By adopting the above technical solution, the two fixing plates respectively clamp the two sides of the connecting I-beam in the width direction, which is beneficial to further ensure the connection stability between the vertical rod and the connecting I-beam. The setting of the rotating handle makes it easy for the staff to apply force to rotate the connecting screw.

[0015] Optionally, the Bailey beam is provided with a clamping and positioning assembly, which includes a fixed block, a clamping and positioning piece, and a driving clamping piece. The fixed block is installed on the Bailey beam, and two clamping and positioning pieces are provided and are respectively located on both sides of the width direction of the connecting I-beam. Both clamping and positioning pieces are rotatably installed on the fixed block, and the driving clamping piece is used to drive the two clamping and positioning pieces to rotate in a direction close to or away from each other.

[0016] By adopting the above technical solution, when the connecting I-beam is located between the two clamping positioning members, the connecting I-beam can be stably positioned by driving the clamping member to drive the two clamping positioning members to rotate in a direction approaching each other until they are in conflict with the connecting I-beam, thereby facilitating the rapid installation of the connecting I-beam to the specified position of the Bailey beam.

[0017] Optionally, the driving clamping member includes a driving connecting rod, a driving rod and a driving screw. The driving screw is vertically penetrated through the fixed block and engaged with the fixed block thread. The driving rod is rotatably installed on one end of the driving screw. The driving rod is slidably engaged with the fixed block in the vertical direction. Two driving connecting rods are corresponding to the clamping positioning member. One end of the driving connecting rod is rotatably installed on the driving rod, and the other end is rotatably installed on the clamping positioning member.

[0018] By adopting the above technical solution, when the driving screw is rotated, the driving rod drives the driving rod to move in the vertical direction due to the cooperation with the thread of the fixed block. At this time, the two driving connecting rods respectively drive the two clamping positioning parts to rotate in the direction of approaching or moving away from each other. The setting of the driving screw makes the operation of rotating the two clamping positioning parts in the direction of approaching or moving away from each other quick and easy.

[0019] Optionally, a buffer pad is fixedly provided on one side of the I-beam where the two clamping positioning members are abutted and connected.

[0020] By adopting the above technical solution, the provision of the buffer pad reduces the wear of the clamping and positioning member when clamping and positioning the connected I-beam, which is beneficial to ensuring the performance of the connected I-beam.

[0021] Optionally, the fixing block is slidably matched with the Bailey beam along the length direction of the Bailey beam, and the fixing block is tightly fixed to the Bailey beam by fixing screws.

[0022] By adopting the above technical solution, the fixing block can be adjusted along the length direction of the Bailey beam and fixed at the adjusted position by fixing screws, thereby facilitating the clamping and positioning of the connecting I-beam at different positions of the Bailey beam, and has strong applicability.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Compared with the temporary support structure directly erected by the disc-locking frame, the temporary support structure composed of the door frame and the disc-locking frame does not need to occupy a large ground space for overall erection, which is conducive to improving the space utilization rate after the temporary support structure is erected. In addition, it is easy to adapt to different terrains and has strong applicability.

[0025] 2. When the fixing plate is pressed against the connected I-beam, the vertical rod and the connected I-beam are firmly fixed. When there is a gap between the fixing plate and the connected I-beam, the fixation between the vertical rod and the connected I-beam is released. The vertical rod and the connected I-beam can be fixed or loosened by rotating the connecting screw. The operation is convenient and fast.

[0026] 3. By driving the clamping member to drive the two clamping positioning members to rotate in a direction close to each other until they are in conflict with the connected I-beam, the stable positioning of the connected I-beam can be achieved, which is convenient for quickly installing the connected I-beam to the specified position of the Bailey beam.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-3 This application is described in further detail.

[0033] The embodiment of the present application discloses a multi-layer combined temporary support structure of a door frame and a buckle frame. Figure 1The multi-layer combined temporary support structure of the portal frame and the disc-hook frame includes a portal frame 1 and a disc-hook frame 2, wherein the portal frame 1 includes a column 101 and a Bailey beam 102 arranged on the top of the column 101. In the embodiment of the present application, two groups of columns 101 are arranged, and the two groups of columns 101 are respectively arranged on both sides of the length direction of the Bailey beam 102. Each group of columns 101 is horizontally arranged along the length direction perpendicular to the Bailey beam 102, and a load-bearing I-beam 3 is horizontally arranged on the top of each group of columns 101, so that the two groups of columns 101 can achieve stable bearing of the Bailey beam 102 by bearing the I-beam 3.

[0034] Continue to refer to Figure 1 The buckle frame 2 includes a vertical unit 201 and a horizontal unit 202. The horizontal unit 202 is arranged at the top of the Bailey beam 102. The vertical unit 201 is provided with two groups and respectively connected to the two sides of the horizontal unit 202 in the length direction. The door frame 1 is located between the two groups of vertical units 201. Specifically, the horizontal unit 202 includes a cross bar 2021, a vertical bar 2022 and an oblique bar 2023 connected to each other. The vertical bars 2022 are distributed in multiple groups along the length direction of the Bailey beam 102. Each group of vertical bars 2022 is evenly distributed along the width direction of the Bailey beam 102. A plurality of connecting I-beams 4 are installed on the top of the Bailey beam 102. The plurality of connecting I-beams 4 are distributed along the length direction of the Bailey beam 102 and are arranged one by one with the plurality of vertical bars 2022. Each vertical bar 2022 is connected to the connecting I-beam 4 through a connecting assembly.

[0035] Reference Figure 2 and Figure 3 The connection assembly includes a connection block 5, a connection screw 6 and a fixing plate 7. The connection block 5 is fixedly installed at the bottom of the vertical rod 2022. The connection block 5 is provided with a sliding groove 8 that penetrates along the horizontal direction. The connecting I-beam 4 penetrates into the sliding groove 8 and slides with the sliding groove 8. The two groove walls opposite to the sliding groove 8 are fixedly connected to the limiting parts 9. When the connecting I-beam 4 slides in the sliding groove 8, the two limiting parts 9 respectively abut against the two sides of the web of the connecting I-beam 4 to ensure the stability of the connecting I-beam 4 when sliding in the sliding groove 8.

[0036] Reference Figure 1 and Figure 3, two groups of connecting screws 6 and fixing plates 7 are provided and are respectively located on both sides of the width direction of the connecting I-beam 4. In the embodiment of the present application, each group of connecting screws 6 and fixing plates 7 is provided with two along the length direction of the connecting I-beam 4. The two groups of connecting screws 6 are penetrated in the horizontal direction and threadedly matched with the connecting I-beam 4. The two groups of fixing plates 7 are respectively fixedly installed on one end of the two groups of connecting screws 6 penetrated in the sliding groove 8 and are arranged directly opposite to each other. The ends of the two connecting screws 6 away from the two fixing plates 7 are fixedly connected with a rotating handle 10, through When the connecting screw 6 is rotated by applying force through the rotating handle 10, the connecting screw 6 drives the fixing plate 7 to move in the direction close to or away from the connecting I-beam 4. When the fixing plate 7 is pressed against the connecting I-beam 4, a firm fixation between the vertical rod 2022 and the connecting I-beam 4 is achieved. When there is a gap between the fixing plate 7 and the connecting I-beam 4, the fixation between the vertical rod 2022 and the connecting I-beam 4 is released. The pressing effect of the two sets of fixing plates 7 on the connecting I-beam 4 is conducive to fully ensuring the connection stability between the vertical rod 2022 and the connecting I-beam 4.

[0037] Reference Figure 3 The top thread of the connecting block 5 is equipped with four positioning screws 11 distributed in a rectangular shape. One end of each positioning screw 11 extends into the sliding groove 8. When the positioning screw 11 is screwed so that the positioning screw 11 is pressed against the connecting I-beam 4 in the vertical direction, it is convenient for personnel to achieve preliminary fixation between the connecting block 5 and the connecting I-beam 4, and then it is convenient to achieve firm fixation between the connecting block 5 and the connecting I-beam 4 by screwing the connecting screw 6 later.

[0038] Reference Figure 2 and Figure 3 In order to facilitate the rapid installation of the connecting I-beam 4 to the designated position on the top of the Bailey beam 102, the Bailey beam 102 is provided with a clamping and positioning assembly, which includes a fixed block 12, a clamping and positioning member 13 and a driving clamping member. The fixed block 12 is fixedly connected with a T-shaped slider 14. The Bailey beam 102 is provided with a T-shaped slide groove 15 that runs through its own length direction. The T-shaped slider 14 slides in the T-shaped slide groove 15. The T-shaped slider 14 is threaded with two horizontally arranged fixing screws 16. When the fixing screws 16 are rotated so that the fixing screws 16 are pressed against the groove wall of the T-shaped slide groove 15, the fixing block 12 and the Bailey beam 102 are tightly fixed.

[0039] Reference Figure 3 Two clamping positioning members 13 are provided and are respectively located on both sides of the width direction of the connecting I-beam 4. The two clamping positioning members 13 are rotatably installed on the fixed block 12. When the connecting I-beam 4 is located between the two clamping positioning members 13 and the two clamping positioning members 13 are rotated to a state of tightening the connecting I-beam 4, the stable positioning of the position of the connecting I-beam 4 is achieved, thereby facilitating the rapid installation of the connecting I-beam 4 to the specified position of the Bailey beam 102.

[0040] Reference Figure 2 and Figure 3 , a buffer pad 17 is provided on the side where the two clamping positioning members 13 are close to each other, that is, the side where the two clamping positioning members 13 abut against the connecting I-beam 4. The material of the buffer pad 17 is selected to be rubber. When the two clamping positioning members 13 rotate, the buffer pad 17 abuts against the connecting I-beam 4 to reduce the wear of the clamping positioning members 13 when clamping and positioning the connecting I-beam 4, thereby ensuring the performance of the connecting I-beam 4. When the two clamping positioning members 13 rotate to a horizontal state, the height of the top of the two clamping positioning members 13 is lower than the height of the bottom of the connecting I-beam 4, so that when the connecting I-beam 4 is located at the position of the Bailey beam 102 and adjusted in the horizontal direction, it is not easy to interfere with the clamping positioning members 13.

[0041] Continue to refer to Figure 2 and Figure 3 The driving clamping member includes a driving connecting rod 18, a driving rod 19 and a driving screw 20. The driving screw 20 is located at the bottom of the connecting I-beam 4. The driving screw 20 is vertically penetrated through the fixed block 12 and is threadedly matched with the fixed block 12. One end of the bottom of the driving screw 20 is fixedly connected to a driving handle 21, so that the staff can apply force to rotate the driving screw 20. The driving rod 19 is rotatably installed on one end of the top of the driving screw 20. The driving rod 19 slides and cooperates with the fixed block 12 in the vertical direction. Two driving connecting rods 18 and the clamping positioning member 13 are correspondingly provided. The two driving connecting rods 18 are respectively arranged near the two ends of the length direction of the driving rod 19. One end of the driving connecting rod 18 is rotatably installed on the driving rod 19, and the other end is rotatably installed on the clamping positioning member 13, so that when the driving screw 20 rotates, the driving rod 19 moves in the vertical direction, and then the two clamping positioning members 13 are driven to rotate in the direction of approaching or moving away from each other through the driving connecting rod 18. The threaded self-locking effect of the driving screw 20 and the fixed block 12 is conducive to fully ensuring the stability of the position of the two clamping positioning members 13 after rotation.

[0042] The implementation principle of a multi-layer combined temporary support structure of a portal frame and a disc frame in an embodiment of the present application is as follows: compared with a temporary support structure directly erected by the disc frame 2, the temporary support structure formed by the combination of the portal frame 1 and the disc frame 2 does not need to occupy a large ground space for overall erection, which is beneficial to improving the space utilization rate after the temporary support structure is erected. At the same time, the uneven ground between the two groups of columns 101 will not affect the erection of the overall temporary support structure, thereby facilitating adaptation to different terrains and having strong applicability. In addition, the Bailey beam 102 can achieve further stable support for the horizontal unit 202 by connecting the I-beam 4 and the setting of the connecting assembly, which is beneficial to fully ensure the overall stability of the temporary support structure.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
