Description

Technical Field

[0001] The utility model relates to the technical field of cap beam construction, in particular to a distribution beam hanging type cap beam door opening formwork construction structure. Background Art

[0002] With the rapid development of cities, the construction of viaducts is increasing, and many cross-line bridges have inevitably appeared. Building bridges on existing roads will inevitably affect the traffic on the roads below. In order to ensure that the basic traffic requirements of existing traffic are maintained during the construction of viaducts, setting up doorway supports has become an effective way to solve this problem.

[0003] The Bailey beam has the characteristics of simple structure, convenient transportation, quick erection, large load-bearing capacity, good interchangeability, and strong adaptability. It can perfectly meet the requirements of short construction period and fast pace, while also meeting the requirements of safety and strong load-bearing capacity. It has gradually been widely used in the construction of bridge projects.

[0004] The Chinese patent with the announcement number CN216809519U discloses a detachable Bailey beam and distribution beam locking device, which includes a Bailey beam and a distribution beam, the Bailey beam and the distribution beam are cross-connected, and the locking device is connected to the intersection of the Bailey beam and the distribution beam. The locking device includes a bottom tray for supporting the Bailey beam, a cover plate for buckling the distribution beam, and a screw connecting the bottom tray and the cover plate. The bottom tray is rectangular and the two ends are folded toward one side of the cover plate to form two flanges, and the distance between the two flanges is adapted to the width of the Bailey beam. The utility model solves the technical problem of the inconvenience of connecting the Bailey beam and the I-beam in the prior art by arranging arc-shaped cover plates and bottom trays on both sides of the intersecting Bailey beam and distribution beam, and fixing them with screws. The device has a simple structure and is easy to operate. A construction worker can stand on the Bailey beam to install it, and the distance between the screw and the distribution beam is large, allowing workers to use a wrench for installation and disassembly, thereby improving construction efficiency.

[0005] With regard to the above-mentioned related technologies, in the prior art, construction workers use the bottom tray to resist the Bailey beam, and use the cooperation of nuts, protective strips and cover plates to stabilize the distribution beam on the Bailey beam. This installation method requires a group of units on both sides of the distribution beam to balance the force on the distribution beam, but it increases the operation steps of the construction workers and prolongs the construction time of the project. In addition, the cover plate in the prior art is arc-shaped, and the contact part between the nut and the cover plate is only a line, which easily reduces the friction between the nut and the cover plate. At the same time, a single nut is matched with the screw rod, and the above-mentioned contact part is less, which makes it easy for the nut to vibrate and loosen the restriction on the cover plate. In this way, the distribution beam is easily displaced by vibration, which increases the incidence of accidents during construction and reduces the firmness of the formwork. Utility Model Content

[0006] In order to improve the firmness of the formwork, the present application provides a distribution beam hanging type cap beam door opening formwork construction structure.

[0007] This application provides a distribution beam hanging cap beam door opening formwork construction structure using the following technical solutions:

[0008] A distribution beam hanging cap beam door opening formwork construction structure includes Bailey beams and distribution beams, the Bailey beams are arranged in several rows in parallel, the distribution beams are arranged at the bottom of the Bailey beams, and a short section channel steel is provided on the top of the Bailey beam. The short section channel steel is a double-piece channel steel. A connecting piece is passed through the middle position between the short section channel steel and the distribution beam. Two locking nuts are threaded on the connecting piece. The locking nuts press against the short section channel steel. The connecting piece is used to assist the locking nuts in applying pressure to the short section channel steel. A positioning component for limiting the installation angle of the distribution beam is provided on the Bailey beam.

[0009] By adopting the above technical solution, during construction, the construction workers first use the positioning assembly to limit the installation angle of the distribution beam, then place the short-section channel steel on the top of the Bailey beam, use the connector to pass through the middle of the short-section channel steel and the distribution beam, and finally use two locking nuts to tighten the short-section channel steel to achieve the installation of the formwork. The construction workers pass the connector through the middle position of the short-section channel steel and the distribution beam, so that the force points of the short-section channel steel and the distribution beam can be concentrated in one position, that is, the middle position of the short-section channel steel and the distribution beam. This not only balances the force position of the distribution beam, but also reduces the number of locking nuts installed, shortening the construction period. The installation of the two locking nuts can further prevent the loosening of the connector. Compared with the existing technology, under the conditions of the gravity of the cap beam and the vibration during construction, it can more stably support the distribution beam, reduce the incidence of accidents during construction, and improve the efficiency and safety of formwork construction.

[0010] Optionally, the positioning assembly includes side limit blocks and middle limit blocks, the distribution beam is a double-piece I-beam, the side limit blocks are connected to two pieces on the Bailey beam, the two side limit blocks are arranged opposite to each other, the middle limit block is connected to the Bailey beam and is located between the two side limit blocks, and the distribution beam is located between the two side limit blocks and the middle limit block.

[0011] By adopting this technical solution, limiting the angle of the distribution beam can improve the installation accuracy of the formwork and enhance its load-bearing capacity. Construction workers installed side and center limit blocks at the bottom of several Bailey beams to limit the relative installation angle of the distribution beam at the bottom of the Bailey beam. This improves the installation accuracy of the distribution beam, facilitates the installation of other formwork components in subsequent steps, and enhances the formwork's installation accuracy and load-bearing capacity.

[0012] Optionally, the connecting piece is a straight threaded steel bar, a short section I-beam is provided at the top of the Bailey beam, the short section I-beam is a double-section I-beam, and a short section channel steel is provided at the top of the short section I-beam and the bottom end of the distribution beam. The connecting piece passes through the short section channel steel, the distribution beam, the Bailey beam and the short section I-beam, and two locking nuts are threadedly fitted at both ends of the connecting piece, and the locking nuts are pressed against the short section channel steel.

[0013] By adopting the above technical solution, the construction workers set the short-section I-beam between the short-section channel steel and the top of the Bailey beam, and then passed the connecting piece through the middle position of the short-section channel steel, the distribution beam and the Bailey beam. Two locking nuts were set at both ends of the connecting piece, and the locking nuts were used to tighten the short-section channel steel, thereby limiting the freedom of the distribution beam and realizing the installation of the distribution beam.

[0014] Optionally, a stabilizing tube is provided on the distribution beam, and a connecting plate is detachably connected to the stabilizing tube at a position corresponding to the distribution beam, and the connecting member is inserted into the stabilizing tube.

[0015] By adopting the above technical solution, during construction, the construction workers will detachably connect the connecting plate to the distribution beam, and then pass the connecting piece through the stabilizing tube, thereby limiting the installation position and angle of the connecting piece and keeping the connecting piece in a vertical state. This can better balance the tightening force of the locking nuts at both ends of the connecting piece and improve the installation accuracy of the formwork.

[0016] Optionally, a partition assembly is provided on the connecting plate, and the partition assembly includes a bidirectional screw, a limiting rod, a moving block and a resistance block. The bidirectional screw is rotatably connected to one connecting plate, the limiting rod is connected to the other connecting plate and is parallel to the bidirectional screw, and two moving blocks are provided on the bidirectional screw and the limiting rod. A fixed plate is connected between the two moving blocks on the same side, and the resistance block is connected to the moving block, and the resistance block resists the Bailey beam.

[0017] By adopting the above technical solution, during construction, the construction workers rotate the bidirectional screw to make the moving blocks at both ends move synchronously, and drive the two moving blocks on the same side to move synchronously through the fixed plate until the interference block interferes with the Bailey beam, thereby adjusting the distance between the two adjacent Bailey beams, ensuring that the installation distance between the two adjacent Bailey beams is equal, and improving the convenience of Bailey beam installation.

[0018] Optionally, the connecting member includes two connecting parts and a supporting part, the supporting part is integrally formed between the two connecting parts, the distribution beam is arranged on the supporting part, and the locking nuts are threadedly engaged with two of the connecting parts.

[0019] By adopting the above technical solution, during construction, the construction workers place the distribution beam on the support part, pass the two connecting parts through the middle position of the short section channel steel, and finally tighten the two locking nuts against the short section channel steel until the distribution beam hits the bottom of the Bailey beam, limiting the degree of freedom of the distribution beam and realizing the construction and installation of the distribution beam.

[0020] Optionally, a straightening plate is detachably connected to the distribution beam, and a positioning groove is provided on the straightening plate at a position corresponding to the connecting portion, and the connecting portion is inserted into the positioning groove.

[0021] By adopting the above technical solution, construction workers limit the installation angles of the two connecting parts through the positioning grooves on the straightening plate, so that the installation angles of several connecting parts are kept consistent, thereby improving the installation accuracy of the connecting parts.

[0022] Optionally, a contact plate is connected to the straightening plate, and the contact plate contacts between the two Bailey beams.

[0023] By adopting the above technical solution, the abutment plate is used to limit the distance between two adjacent Bailey beams, so that the spacing between several Bailey beams is kept consistent, thereby improving the installation stability of the distribution beam.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. During construction, the construction workers first use the positioning assembly to define the installation angle of the distribution beam, then place the short-section channel steel on the top of the Bailey beam, use the connector to pass through the middle of the short-section channel steel and the distribution beam, and finally use two locking nuts to tighten the short-section channel steel to achieve the installation of the formwork. The construction workers pass the connector through the middle position of the short-section channel steel and the distribution beam, so that the force points of the short-section channel steel and the distribution beam can be concentrated in one position, that is, the middle position of the short-section channel steel and the distribution beam. This not only balances the force position of the distribution beam, but also reduces the number of locking nuts installed, shortening the construction period. The installation of the two locking nuts can further prevent the connector from loosening. Compared with the existing technology, under the conditions of the gravity of the cap beam and the vibration during construction, it can more stably support the distribution beam, reduce the incidence of accidents during construction, and improve the efficiency and safety of formwork construction.

[0026] 2. During construction, the construction workers rotate the bidirectional screw to make the moving blocks at both ends move synchronously, and drive the two moving blocks on the same side to move synchronously through the fixed plate until the interference block interferes with the Bailey beam, thereby adjusting the distance between the two adjacent Bailey beams, ensuring the installation distance between the two adjacent Bailey beams, and improving the convenience of Bailey beam installation.

[0035] The following is combined with Figure 1-Figure 7 This application is described in further detail.

[0036] Example 1 of the present application discloses a distribution beam hanging type cap beam door opening formwork construction structure. Figure 1 The distribution beam hanging cap beam door formwork construction structure includes a Bailey beam 1 and a distribution beam 2. Several Bailey beams 1 are set. In this embodiment, several Bailey beams 1 are divided into three rows. The distribution beam 2 is a double-piece I-beam, and the distribution beam 2 is set at the bottom of the Bailey beam 1.

[0037] Reference Figure 2 Bailey beam 1 is provided with a positioning assembly 3 comprising side restraints 31 and a center restraint block 32. Two side restraint blocks 31 are welded to Bailey beam 1, facing each other. The center restraint block 32 is welded to Bailey beam 1 and positioned between the two side restraint blocks 31. The distribution beam 2 is positioned between the two side restraint blocks 31 and the center restraint block 32. The coordination of the two side restraint blocks 31 and the center restraint block 32 limits the installation angle of the distribution beam 2, improving the installation accuracy of the overall formwork.

[0038] Reference Figure 2 and Figure 3 The top of the Bailey beam 1 is provided with a short I-beam 4, which is a double-jointed I-beam. A short channel steel 41 is provided at the top of the short I-beam 4 and at the bottom of the distribution beam 2. The short channel steel 41 is a double-jointed channel steel. A connector 5 is provided between the two short channel steels 41. The connector 5 is a straight threaded steel bar. The connector 5 is inserted in the middle of the two short channel steels 41 and also passes through the middle of the short I-beam 4. Both ends of the connector 5 are threaded with two locking nuts 51, which press against the short I-beam 4.

[0039] During construction, the construction workers first thread the two locking nuts 51 into the bottom end of the connector 5, and then use the short-section channel steel 41 to support the distribution beam 2 until the distribution beam 2 touches the bottom of the Bailey beam 1. Then, the short-section I-beam 4 and the short-section channel steel 41 are placed on the top of the Bailey beam 1 in sequence, so that the connector 5 passes through the short-section I-beam 4 and the short-section channel steel 41, and finally the two locking nuts 51 are threaded into the top end of the connector 5 to complete the installation of the distribution beam 2.

[0040] Reference Figure 3 and Figure 4 A stabilizing tube 6 is provided at the position corresponding to the connecting member 5 on the distribution beam 2. A connecting plate 61 is connected to the stabilizing tube 6 at the position corresponding to the distribution beam 2 by bolts, and the connecting member 5 is inserted into the stabilizing tube 6. A partition assembly 7 is provided on the connecting plate 61. The partition assembly 7 includes a bidirectional screw 71, a limiting rod 72, a moving block 73 and a resistance block 74. The bidirectional screw 71 is rotatably connected to one of the connecting plates 61, and the limiting rod 72 is fixedly connected to the other connecting plate 61 and is arranged parallel to the bidirectional screw 71. Two moving blocks 73 are provided on each of the bidirectional screw 71 and the limiting rod 72, and a fixed plate is welded between the two moving blocks 73 on the same side. The resistance block 74 is fixedly connected to the moving block 73, and the resistance block 74 is attached to the connecting plate 61 and resists the Bailey beam 1. A stabilizing tube 6 is also provided at the bottom of the short section I-beam 4.

[0041] When separating several Bailey beams 1, the construction workers rotate the bidirectional screw 71 to make the moving blocks 73 on both sides move synchronously, driving the abutment blocks 74 to move until the abutment blocks 74 abut the side walls of the Bailey beam 1, thereby adjusting the distance between two adjacent Bailey beams 1.

[0042] The implementation principle of the distribution beam hanging cap beam door opening formwork construction structure in Example 1 of the present application is as follows: during construction, the construction personnel thread the two locking nuts 51 into the bottom end of the connecting piece 5, and use the short section channel steel 41 to support the distribution beam 2. The connecting piece 5 passes through the stabilizing tube 6 until the distribution beam 2 contacts the bottom of the Bailey beam 1. The bidirectional screw 71 is rotated to make the moving blocks 73 on both sides move synchronously, driving the contact block 74 to contact the side wall of the Bailey beam 1 to adjust the distance between the two adjacent Bailey beams 1. Subsequently, the short section I-beam 4 and the short section channel steel 41 are placed on the top of the Bailey beam 1 in sequence. Finally, the two locking nuts 51 are threaded into the top of the connecting piece 5 to realize the installation of the distribution beam 2.

[0043] The construction workers pass the connecting piece 5 through the middle position of the short section channel steel 41 and the distribution beam 2, so that the force points of the short section channel steel 41 and the distribution beam 2 can be concentrated in one position, that is, the middle position of the short section channel steel 41 and the distribution beam 2. This not only balances the force positions of the distribution beam 2, but also reduces the number of installation of the locking nuts 51, shortens the construction period, and the installation of the two locking nuts 51 can further prevent the connecting piece 5 from loosening. Compared with the existing technology, under the conditions of the gravity of the cap beam and the vibration during construction, it can more stably support the distribution beam 2, reduce the occurrence rate of accidents during construction, and improve the efficiency and safety of formwork construction.

[0044] Example 2: The difference between this example and Example 1 lies in the different structure of the connecting member 5 .

[0045] Reference Figure 5 and Figure 6 The connector 5 includes two connecting portions 52 and a supporting portion 53. The supporting portion 53 is integrally formed between the two connecting portions 52. The connector 5 is U-shaped, and the distribution beam 2 is located between the two connecting portions 52 and abuts the supporting portion 53. Two short-section channel steels 41 are provided at the top of the Bailey beam 1. The short-section channel steels 41 are double-piece channel steels, and the connecting portions 52 pass through the middle position of the short-section channel steels 41. Two locking nuts 51 are threadedly engaged on the connecting portions 52, and the locking nuts 51 are tightly against the short-section channel steels 41.

[0046] Reference Figure 7 A straightening plate 8 is bolted to the distribution beam 2. A positioning slot 81 is formed on the straightening plate 8 at the position corresponding to the connection portion 52, and the connection portion 52 is inserted into the positioning slot 81. A contact plate 82 is welded to the straightening plate 8, and the contact plate 82 contacts between the two Bailey beams 1. A straightening plate 8 is also provided at the bottom of the short section channel steel 41.

[0047] During construction, the construction workers place the short-section channel steel 41 on the Bailey beam 1, place the distribution beam 2 on the support part 53, pass the connecting part 52 through the positioning groove 81, and then move the connecting part 5 until the distribution beam 2 touches the bottom of the Bailey beam 1. The connecting part 52 passes through the short-section channel steel 41, and finally rotate the two locking nuts 51 to complete the installation of the distribution beam 2.

[0048] Due to the shape limitation of the connecting member 5 , the positioning assembly 3 in this embodiment enables the distribution beam 2 to be compactly arranged (double I-beams are fitted together), so the middle limit block 32 in the positioning assembly 3 in this embodiment is omitted.

[0049] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
