An adjustable building formwork support

Abstract

This utility model discloses an adjustable building formwork support, including a support base plate. An adjustment auxiliary mechanism is provided at the lower end of the support base plate. The adjustment auxiliary mechanism includes a fixing block fixedly connected to the lower end of the support base plate, and a support leg movably connected to the outer side of the fixing block. An adjustment frame is fixedly connected to the lower end of the support base plate near the fixing block, and a sliding groove is provided at the front end of the adjustment frame. The adjustable building formwork support of this utility model allows the adjustment rod to slide within the adjustment frame and the threaded rod to slide within the sliding groove by pulling down the support base plate. This also causes the support base plate to rotate around a pivot axis within the inner side of the support leg. Tightening the internal threaded ring further limits the angle between the support base plate and the support leg, thus limiting the tilt angle of the support base plate and allowing it to be adjusted to a suitable angle, thereby facilitating the support of the stair formwork.

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-4 As shown, an adjustable building formwork support includes a support base plate 1. An adjustment auxiliary mechanism 7 is provided at the lower end of the support base plate 1. The adjustment auxiliary mechanism 7 includes a fixing block 71 fixedly connected to the lower end of the support base plate 1. A support leg 72 is movably connected to the outer side of the fixing block 71. An adjustment frame 73 is fixedly connected to the lower end of the support base plate 1 near the fixing block 71. A sliding groove 74 is provided at the front end of the adjustment frame 73. A rotating shaft 75 is movably connected to the inside of the fixing block 71. An adjustment rod 76 is movably connected to the inner side of the adjustment frame 73. A threaded rod 77 is movably connected to the inside of the adjustment rod 76. The outer side of the threaded rod 77 is movably connected to the inner side of the sliding groove 74. An internal threaded ring 78 is threadedly connected to the outer side of the threaded rod 77 near the front side of the sliding groove 74. A fixing plate 79 is fixedly connected to the front end of the support leg 72. A support shaft 710 is movably connected to the inside of the adjustment rod 76 near the lower side of the threaded rod 77.

[0021] In this embodiment, a cross bracket 711 is fixedly connected to the rear end of the support leg 72, a rotating shaft 75 extends into the interior of the support leg 72, and the rotating shaft 75 is movably connected to the support leg 72. The internal threaded ring 78 is in contact with the adjusting frame 73, and the support shaft 710 extends into the interior of the fixed plate 79, and the support shaft 710 is movably connected to the fixed plate 79. There are two sets of support legs 72, and the two sets of support legs 72 are connected by the cross bracket 711. There are two sets of adjusting frames 73 and two sets of adjusting rods 76.

[0022] Specifically, the bracket base plate 1 is tilted downwards, causing the adjusting rod 76 to slide within the adjusting frame 73 and the threaded rod 77 to slide within the sliding groove 74. Simultaneously, the adjusting rod 76 rotates about the support shaft 710, causing the bracket base plate 1 to rotate around the rotation shaft 75 within the inner side of the bracket leg 72. This adjusts the bracket base plate 1 to the specified tilt angle. Then, the internal threaded ring 78 is tightened, limiting the angle between the bracket base plate 1 and the bracket leg 72, thus limiting the tilt angle of the bracket base plate 1 and adjusting it to a suitable angle. The support base plate 1 supports the stair mold. By pulling down the support base plate 1, the adjusting rod 76 slides in the adjusting frame 73, and the threaded rod 77 slides in the sliding groove 74. The support base plate 1 drives the fixing block 71 to rotate around the rotating shaft 75 on the inner side of the support leg 72. Then, the inner threaded ring 78 is tightened. This can achieve the purpose of limiting the included angle between the support base plate 1 and the support leg 72, thereby limiting the tilt angle of the support base plate 1 and adjusting the support base plate 1 to a suitable angle, so as to facilitate the support base plate 1 to support the stair mold.

[0023] In this embodiment, a crossbar 2 is fixedly connected to the inner wall of the support base plate 1. A connecting block 3 is fixedly connected to the lower end of the support base plate 1 near the control frame 73. An adjustment frame 4 is movably connected to the outer side of the connecting block 3. A support leg 6 is slidably connected to the inner side of the adjustment frame 4 near the lower side of the connecting block 3. A movable shaft 5 is movably connected inside the connecting block 3. A bolt 8 is threadedly connected inside the support leg 6. The adjustment frame 4 is U-shaped. The movable shaft 5 extends into the interior of the adjustment frame 4 and is movably connected to the adjustment frame 4. The bolt 8 extends into the interior of the adjustment frame 4 near the lower side of the movable shaft 5 and is threadedly connected to the adjustment frame 4. There are two sets of connecting blocks 3, adjustment frames 4, and support legs 6.

[0024] Specifically, the worker first places the support base plate 1 in the designated position, then loosens the internal threaded ring 78 and unscrews the bolt 8, and pulls the adjusting frame 4 downward, causing the adjusting frame 4 to slide downward along the support leg 6. At the same time, the adjusting frame 4 drives the connecting block 3 to move downward through the movable shaft 5, and changes the included angle between the connecting block 3 and the adjusting frame 4. Then, the bolt 8 is screwed into the adjusting frame 4 and the support leg 6, thus limiting the included angle between the support base plate 1 and the adjusting frame 4.

[0025] Working principle:

[0026] In use, the worker first places the support base plate 1 in the designated position, then loosens the internal threaded ring 78 and unscrews the bolt 8, and pulls the adjusting frame 4 downward, causing it to slide downward along the support leg 6. Simultaneously, the adjusting frame 4, via the movable shaft 5, moves the connecting block 3 downward, changing the angle between the connecting block 3 and the adjusting frame 4. This causes the support base plate 1 to tilt downward, allowing the adjusting rod 76 to slide within the adjusting frame 73 and the threaded rod 77 to slide within the sliding groove 74. Simultaneously, the adjusting rod 76 rotates about the support shaft 710, causing the support base plate 1 to rotate the fixing block 71 within the support leg 72 about the rotating shaft 75, thus adjusting the support base plate 1 to the designated tilt angle. Then, the internal threaded ring 78 is tightened, thus tightening the clamp between the support base plate 1 and the support leg 72. By limiting the angle and then tightening the bolt 8 into the adjusting frame 4 and the support leg 6, the included angle between the support base plate 1 and the adjusting frame 4 is limited, thus limiting the tilt angle of the support base plate 1. This allows the support base plate 1 to be adjusted to a suitable angle, thereby facilitating the support of the stair mold. By pulling down the support base plate 1, the adjusting rod 76 slides in the adjusting frame 73, and the threaded rod 77 slides in the sliding groove 74. This also causes the support base plate 1 to drive the fixing block 71 to rotate around the rotating shaft 75 on the inner side of the support leg 72. Then, by tightening the inner threaded ring 78, the included angle between the support base plate 1 and the support leg 72 can be limited, thus limiting the tilt angle of the support base plate 1. This allows the support base plate 1 to be adjusted to a suitable angle, thereby facilitating the support of the stair mold.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
