Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of deformation joint support, in particular to a deformation joint support device. BACKGROUND

[0002] The deformation joint is a construction joint set to deal with the deformation of the building due to factors such as temperature, humidity, earthquake, etc. In the traditional process, extruded board (or other foam board) is often used as a separation material on the inside of the formwork, but the formwork often lacks sufficient keel support, resulting in insufficient stiffness. When pouring concrete on both sides at the same time, the concrete may be squeezed to the opposite side due to the vibration process, causing the concrete structure on both sides of the deformation joint to expand, displace, and other quality accidents. The formwork removal will become difficult, and manual tools will be needed to crush and clean the extruded board, causing great interference and waste to the construction progress.

[0003] This not only affects the appearance quality of the building, but also may affect its use function and safety. This traditional construction method not only has low efficiency, but also increases the construction cost. A cast-in-place concrete double-beam deformation joint formwork support device is disclosed in Chinese patent (publication number: CN209855286U), which can avoid quality accidents such as expansion and displacement of the concrete structure on both sides of the deformation joint during pouring, and also facilitates formwork removal while adjusting the distance between the two formworks according to the width of the deformation joint, which can further improve the use range.

[0004] However, the top end of the two formworks in the above-mentioned document is not provided with a shielding structure, which causes debris, dust, etc. to fall into the space between the two formworks, so that the deformation joint needs to be cleaned during subsequent caulking, thereby causing inconvenience to the subsequent process. CONTENT OF THE UTILITY MODEL

[0005] In view of the deficiencies of the prior art, the present application provides a deformation joint support device, which has the advantages of convenient shielding, and solves the problem of inconvenient shielding.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a deformation joint support device, comprising a support assembly, the support assembly comprising two support formworks, a double-shaft screw, two groups of push rods and two displacement blocks, the top end of the two support formworks being provided with a top sealing assembly;

[0007] The top sealing assembly comprises two narrow plates, two sleeve plates, two telescopic plates fixedly installed on the opposite wall of the two narrow plates, two support blocks fixedly installed at the top end of the telescopic plates, and a splicing structure fixedly installed at the back side of the two narrow plates.

[0008] The space between the two supporting templates can be shielded, so that sundries and dust cannot fall into the space between the two supporting templates, and the deformed joint needs to be cleaned when the deformed joint is subsequently filled.

[0009] Further, the bottom walls of the two narrow plates are fixed to the top ends of the two supporting templates, and the sleeve plates are rectangular with hollow interiors and missing left and right ends.

[0010] The above technical solution enables the telescopic plates to move into or out of the interiors of the sleeve plates.

[0011] Further, the opposite sides of the two sleeve plates are each provided with a semicircular groove, and the opposite sides of the front and rear groups of telescopic plates are each provided with an arc-shaped groove.

[0012] The above technical solution reserves a space for operating the double-shaft screw.

[0013] Further, the top wall of the interior of the sleeve plate is provided with two sliding grooves, and the supporting blocks are slidingly connected to the interiors of the sliding grooves.

[0014] The above technical solution enables the telescopic plates to be prevented from being completely pulled out of the interiors of the sleeve plates when the telescopic plates move out of the interiors of the sleeve plates.

[0015] Further, the splicing structure comprises two splicing blocks, two supporting plates, a horizontal plate fixedly installed at the front end of the splicing block, a pull plate hingedly fixedly installed at the front end of the horizontal plate, a moving block fixedly installed at the other end of the pull plate, and a stop block fixedly installed at the left and right walls of the horizontal plate, and a threaded rod is rotatably connected to the top end of the moving block through a bearing.

[0016] The above technical solution enables two adjacent supporting assemblies to be stably spliced together, so as to further improve the supporting strength of the supporting assembly.

[0017] Further, the rear ends of the two narrow plates are each provided with a groove, the supporting plates are fixedly installed in the interiors of the grooves, and the front ends of the supporting plates are provided with through holes for sliding the horizontal plate therein.

[0018] The above technical solution enables the horizontal plate to be stably moved in the groove of the narrow plate through the supporting plate.

[0019] Further, the front ends of the two narrow plates are each provided with a splicing groove for inserting the splicing block into the interior thereof.

[0020] The above technical solution enables the splicing block to move into the splicing groove, and enables two adjacent supporting assemblies to be stably spliced together, so as to prevent the phenomenon of misalignment of multiple supporting assemblies.

[0021] Further, the top end of each of the two narrow plates is provided with a threaded hole for allowing a threaded rod to move into the hole, and the threaded hole is in communication with the groove.

[0022] The above technical solution allows the threaded rod to move in the groove of the narrow plate, thereby facilitating the threaded rod to drive the moving block to move up and down in the groove of the narrow plate.

[0023] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0024] The deformation joint support device can shield the top end of the two support templates to prevent sundries and dust from falling into the space between the two support templates, thereby avoiding the need to clean the deformation joint during subsequent joint filling, and the adjacent two support assemblies can be stably spliced together to further improve the support strength of the support assembly.

[0036] The bottom walls of the two narrow plates 21 are fixedly installed on the top ends of the two support templates 11, the sleeve plates 22 are rectangular with the left and right ends missing, so that the telescopic plates 23 can slide in the interiors of the sleeve plates 22, and when the distance between the two support templates 11 is expanded, the support templates 11 drive the telescopic plates 23 to move out of the interiors of the sleeve plates 22 through the narrow plates 21, so as to extend the width of the capping assembly.

[0037] In addition, the opposite sides of the two sleeve plates 22 are each provided with a semicircular groove, and the double-shaft screw rod 12 can extend from the bottom to the top of the two sleeve plates 22 through the two semicircular grooves, so as to facilitate the staff to rotate it, and the opposite sides of the front and rear groups of telescopic plates 23 are each provided with an arc-shaped groove, so that the telescopic plates 23 can be attached to the inner walls of the sleeve plates 22.
