Description

Technical Field

[0001] The utility model belongs to the field of building template support structures, in particular to a disc-type steel pipe frame template support structure. Background Art

[0002] In construction projects, traditional formwork systems were mostly made of wood, making them difficult to adjust in size and height. Later, they evolved into steel and wood formwork brackets. However, this system was labor-intensive, material-intensive, and inefficient to assemble and construct. With the development of society and the economy, steel formwork has become widely used due to its scalability, high strength, and reusability. However, traditional formwork systems are no longer able to meet the demands of modern architecture, especially high-rise buildings and large-scale construction projects. Therefore, my country has introduced a disc-type formwork support system.

[0003] The disc-type formwork support's disc-type nodes include connecting plates welded on the vertical poles and rod-end buckle joints on the horizontal poles. The pins are hammered into the connecting plates to connect the bracket sections to each other. Even though the pins have simple anti-fall-off structural measures, the brackets continue to vibrate during construction operations, and there is still a risk that the pins will loosen and detach from the connecting plates, causing the disc-type formwork support to become loose, which is very likely to cause a safety hazard. Utility Model Content

[0004] The utility model aims to solve the problem that the latch pins at the buckle nodes of the buckle type template support are easy to loosen and fall off.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a disc-type steel pipe frame formwork support structure, including vertical poles, horizontal poles, connecting plates and fixing devices; the connecting plates are fixed on the vertical poles, the joints at the ends of the horizontal poles are plugged into the connecting plates, the fixing device includes a sliding assembly, the sliding assembly includes a fixed block, the fixed block is fixed to the top of the horizontal pole, a tooth block that can slide left and right is provided inside the fixed block, a tooth column that can slide up and down is provided inside the fixed block, when the tooth block slides to the right position, the tooth column engages with the teeth of the tooth block, when the tooth block slides to the left position, the tooth column separates from the tooth block, a bolt rod is connected to the bottom of the tooth column, the bolt rod is plugged into the socket of the connecting plate, and a window for toggling the tooth block is opened on the fixed block.

[0006] Furthermore, a positioning block capable of sliding left and right is provided in the fixed block, the tooth block is mounted on the positioning block, and a rebound spring is connected between the positioning block and the inner wall of the fixed block.

[0007] Furthermore, telescopic springs are connected between the top and bottom of the tooth block and the positioning block.

[0008] Furthermore, a pull rod is connected to the gear column.

[0009] Furthermore, a support rod assembly is provided on the surface of the bolt rod, and the support rod assembly includes a groove, which is opened on the surface of the bolt rod; a rotating rod is fixedly connected in the groove, and a tilting rod is rotatably connected to the rotating rod, the tilting rod is engaged with the bolt rod, and a support spring is fixedly connected to the surface of the tilting rod; one end of the support spring away from the tilting rod is fixedly connected to the inner wall of the groove, and a blocking block is fixedly connected to the surface of the groove, and the upper surface of the blocking block is against the surface of the tilting rod.

[0010] Furthermore, a cross groove is provided on the surface of the bolt rod; a cross block is slidably connected to the inner wall of the cross groove, a contraction spring is fixedly connected to the surface of the cross block, an end of the contraction spring away from the cross block is fixedly connected to the inner wall of the cross groove, a sliding cap is fixedly connected to the surface of the cross block, and the sliding cap is against the surface of the tilting rod.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] The utility model provides a disc-type steel pipe frame formwork support structure with two safety lines of defense to prevent the bolt rod from falling out of the connecting disk. The first line of defense is the engagement of the teeth of the tooth block and the tooth column, and the rebound spring always pushes the tooth block toward the tooth column. In the absence of external force, the tooth block and the tooth column always remain in an engaged state, preventing the bolt rod from falling out of the connecting disk; the second line of defense is that the tilting rod on the bolt rod remains in an open state under the push of the supporting spring, preventing the tail of the bolt rod from falling out of the socket of the connecting disk.

DETAILED DESCRIPTION

[0019] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0020] like Figure 1 、 Figure 2 、 Figure 3 As shown: a disc-type steel pipe frame template support structure, including a vertical pole 1, a horizontal pole 2, a connecting plate 5 and a fixing device 6; the connecting plate 5 is fixed to the vertical pole 1, the joint at the end of the horizontal pole 2 is plugged into the connecting plate 5, the fixing device 6 includes a sliding component 61, the sliding component 61 includes a fixing block 611, the fixing block 611 is fixed to the top of the horizontal pole 2, the fixing block 611 is provided with a tooth block 613 that can slide left and right, the fixing block 611 is provided with a tooth column 616 that can slide up and down, the tooth block 613 slides When the tooth column 616 is in the right position, the tooth column 616 is engaged with the teeth of the tooth block 613. When the tooth block 613 slides to the left position, the tooth column 616 is separated from the tooth block 613. The bottom of the tooth column 616 is connected to the bolt rod 62, which is plugged into the socket of the connecting disk 5. A window for moving the tooth block 613 is opened on the fixed block 611. When the tooth column 616 is engaged with the teeth of the tooth block 613, the tooth column 616 and the bolt rod 62 cannot slide up and down, so the bolt rod 62 cannot fall out of the socket of the connecting disk 5, which increases safety.

[0021] A positioning block 612 that can slide left and right is provided in the fixed block 611, and the tooth block 613 is installed on the positioning block 612. A rebound spring 615 is connected between the positioning block 612 and the inner wall of the fixed block 611. The elastic force of the rebound spring 615 pushes the positioning block 612 so that the tooth block 613 and the tooth column 616 in the positioning block 612 always remain in an engaged state. When the tooth column 616 needs to be moved, the tooth block 613 is pressed hard, and the tooth block 613 overcomes the elastic force of the rebound spring 615 and moves to the left.

[0022] A telescopic spring 614 is connected between the top and bottom of the tooth block 613 and the positioning block 612, which can lift the tooth block 613 upward so that the tooth block 613 always applies downward pressure to the tooth column 616, making the plug rod 62 and the connecting plate 5 more tightly connected.

[0023] A pull rod 617 is connected to the tooth column 616, and the pull rod 617 is used to facilitate lifting the tooth column 616 and the bolt rod 62.

[0024] like Figure 4 、 Figure 5 As shown: a support rod assembly 63 is provided on the surface of the bolt rod 62, and the support rod assembly 63 includes a groove 631, which is opened on the surface of the bolt rod 62; a rotating rod 632 is fixedly connected in the groove 631, and a tilting rod 634 is rotatably connected to the rotating rod 632, and the tilting rod 634 is engaged with the bolt rod 62, and a support spring 633 is fixedly connected to the surface of the tilting rod 634; one end of the support spring 633 away from the tilting rod 634 is fixedly connected to the inner wall of the groove 631, and a blocking block 635 is fixedly connected to the surface of the groove 631, and the upper surface of the blocking block 635 is against the surface of the tilting rod 634.

[0025] A cross groove 636 is formed on the surface of the bolt rod 62; a cross block 637 is slidably connected to the inner wall of the cross groove 636, and a contraction spring 638 is fixedly connected to the surface of the cross block 637. The end of the contraction spring 638 away from the cross block 637 is fixedly connected to the inner wall of the cross groove 636, and a sliding cap 639 is fixedly connected to the surface of the cross block 637, which abuts against the surface of the tilting rod 634.

[0026] The bolt rod 62 slides downward, and after the bolt rod 62 passes through the socket of the connecting plate 5, the sliding cap 639 slides upward, and the sliding cap 639 separates from the surface of the tilting rod 634. The tilting rod 634 will pop out from the bolt rod 62 due to the elastic force of the supporting spring 633, and finally hit the blocking block 635. When the bolt rod 62 needs to be pulled out of the socket of the connecting plate 5, the sliding cap 639 is slid upward, and then the tilting rod 634 is pressed back into the groove 631 of the bolt rod 62.

[0027] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
