[0031] See Figure 1 The utility model provides a support frame for installing prefabricated beams, which is used to install prefabricated beams on bridge piers. The support frame includes: a frame body 1, a movable ring 2, a hinge seat 3, and an extension arm 4. The hinge seat 3 is rotatably arranged on both side ends of the frame body 1, and the extension arm 4 is arranged on the hinge seat 3.

[0032] Preferably, if Figure 1 As shown, the movable ring 2 can be rotated and adjusted through the movable groove 1, and its movement range can be limited during the rotation process of the movable ring 2.

[0033] See Figure 1 、 Figure 2 In a specific embodiment of the present invention, movable grooves 11 are provided at both ends of the frame body 1, and movable rings 2 connected to the hinge seat 3 are inserted into the movable grooves 11.

[0034] Further, if Figure 1 、 Figure 2As shown, by setting the square frame shape, the movable ring 2 can be clamped in the movable groove 11 by the corner clamps around the frame during rotation adjustment, thereby increasing the friction force, achieving a limiting effect, and preventing the movable ring 2 from rotating on its own.

[0035] See Figure 1 、 Figure 2 In a specific embodiment of the present invention, the movable ring 2 is a square ring, one ring arm of the movable ring 2 is connected to the hinge seat 3, and the other ring arm opposite is inserted into the movable groove 11. The movable ring 2 can be rotated and adjusted around the ring arm inserted into the movable groove 11, so that the hinge seat 3 is located above the frame body 1 or on the side of the frame body 1.

[0036] Further, if Figure 1 、 Figure 2 As shown, the side length of the movable ring 2 is consistent with the inner diameter of the movable groove 11, so that the movable ring 2 is more stably wrapped in the movable groove 11.

[0037] See Figure 1 、 Figure 2 In a specific embodiment of the present invention, the two movable rings 2 on the frame body 1 are arranged in parallel.

[0038] See Figure 1 、 Figure 2 In a specific embodiment of the present invention, a T-shaped connecting plate 21 is connected to the movable ring 2 , and the connecting plate 21 is installed at the bottom of the hinge seat 3 .

[0039] See Figure 1 、 Figure 2 In a specific embodiment of the present invention, the connecting plate 21 includes a vertical plate connected to the movable ring 2 and a horizontal plate connected to the hinge seat 3.

[0040] See Figure 1 、 Figure 2 In a specific embodiment of the present invention, a movable block 31 is installed on the hinge seat 3, and the movable block 31 is connected to the extension arm 4.

[0041] Further, if Figure 1 、 Figure 2 As shown, the movable block 31 can be angle-adjusted by hinge connection with the hinge seat 3, thereby solving the problem that the angle of the support frame cannot be adjusted when in use. The hinge seat 3 and the movable block 31 are combined to form a rotation adjustment component.

[0042] See Figure 2 In a specific embodiment of the present invention, the movable block 31 includes a vertical plate connected to the hinge seat 3 and a horizontal plate connected to the extension arm 4.

[0043] See Figure 4 In a specific embodiment of the present invention, the extension arm 4 includes a first arm tube and an extension plate 41 partially inserted into the first arm tube. The length of the connecting portion between the extension plate 41 and the first arm tube is adjustable, and a plurality of protrusions 42 are connected to the extension plate 41.

[0044] Preferably, if Figure 4 As shown, the extension plate 41 is adjusted up and down in the extension arm 4, so that the support frame can be adjusted in length according to needs during the installation process, and the extension arm 4 is combined with the extension plate 41 to form an extension fixing component.

[0045] Furthermore, by providing a plurality of protrusions 42 , the supporting contact area with the prefabricated beam can be increased.

[0046] Furthermore, the extension plate 41 increases the support range for the precast beam through the square setting, and can also be applied to precast beams of multiple different sizes.

[0047] See Figure 4 In a specific embodiment of the present invention, the protrusions 42 are arranged in a circular shape and in a linear equidistant array on the extension plate 41 .

[0048] Further, if Figure 4 As shown, the protrusion 42 is made of elastic material and can adapt to prefabricated beams of different shapes and sizes.

[0049] like Figures 1 to 4 As shown, the installation process of a support frame for installing a prefabricated beam of the present invention is described below.

[0050] First, the frame body 1 can be pre-buried into the concrete, and then the movable ring 2 can be used to move freely inside the movable groove 11, so that the connecting plate 21 can move freely to a suitable position. The hinge seat 3 can facilitate the T-shaped connecting plate 21 to drive the extension arm 41 to rotate to the position area where the prefabricated beam needs to be installed and fixed. The movable ring 2 can be placed in the groove 11 to rotate freely to adapt to the required position of prefabricated beams of different sizes, and then the extension plate 41 inside the extension arm 4 is pulled, so that the extension plate 41 can be pulled out to adapt to prefabricated beams of different lengths.

[0051] The beneficial effects of the support frame for installing prefabricated beams of the utility model are:

[0052] By using the movable adjustment component, the rotation adjustment component and the extension fixing component, the movable block on the hinge seat can be driven to rotate freely, and the placement slot can also be freely rotated to adapt to the required position of prefabricated beams of different sizes. The extension plate inside the sliding slot can be used to pull out the extension 1 to adapt to prefabricated beams of different sizes and lengths, preventing the prefabricated beams from being unable to be installed due to the inability to rotate the angle and extend the length, which brings a lot of convenience to the installation personnel to a certain extent.

[0053] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. A person skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention. The scope of protection of the present invention shall be determined by the scope defined in the appended claims.
