[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] like Figure 1-Figure 5 As shown, this embodiment provides an adjustable device for a precast beam notch, which is suitable for a precast beam notch to adapt to notches of different widths. The adjustable device for a precast beam notch includes a first clamp 1, a second clamp 2, and a fastener 3 adjustably connected to the first clamp 1 and the second clamp 2.

[0031] Specifically, the first clamp 1 and the second clamp 2 are respectively abutted against opposite sides of the notch 4 to ensure that the device is stably fixed at the notch 4. The fastener 3 is adjustably connected between the first clamp 1 and the second clamp 2. By changing the position of the fastener 3 on the first clamp 1, the overall length of the device can be adjusted to adapt to the reinforcement of the notch of the precast beam with different widths, so as to facilitate the demoulding and hoisting of the precast beam with the notch and prevent the line at the notch from breaking.

[0032] Furthermore, if Figure 1 and Figure 2 As shown, the first clamping member 1 includes a first support 11 and a first connecting rod 12, and the first support 11 abuts against one side of the notch; the first support 11 is fixedly connected to the first connecting rod 12, and the first connecting rod 12 can be movably connected to the fastener 3. An adjustable adjusting member 13 is also provided on the outer wall of the first connecting rod 12, and when the device is used, the adjusting member 13 abuts against one end of the fastener 3. More specifically, the outer wall of the first connecting rod 12 is provided with threads, preferably a screw; the adjusting member 13 adopts a nut, preferably an adjusting nut, and when the fastener 3 is adjusted to the desired position, the adjusting member 13 abuts against the fastener 3, and the adjusting member 13 serves to limit or control the relative position, which can ensure the stability of the adjustment, and is firmly fixed to the first connecting rod 12 through a threaded connection.

[0033] Specifically, the second clamp 2 includes a second connecting rod 21, a baffle 22, a third connecting rod 23 and a second support 24 which are fixedly connected in sequence, the second support 24 abuts against the other side of the prefabricated beam notch 4, the baffle 22 abuts against the end of the fastener 3, and the second connecting rod 21 is embedded in the fastener 2. A third connecting rod 23 is also arranged between the second support 24 and the baffle 22, and these components are fixedly connected in sequence to form a stable structure.

[0034] In order to improve the stability of the device, the first support 11 and the second support 24 are designed to be truncated cone-shaped, which can better disperse the pressure; the first connecting rod 12, the second connecting rod 21, and the third connecting rod 23 are arranged horizontally, and are perpendicular to the first straight line 11 or the second support 24. The shape of the baffle 22 is designed to be circular. The fastener 3 is a tubular structure with threads arranged inside, and this design allows the fastener 3 to be easily connected to the first connecting rod 12 and the second connecting rod 21. More specifically, the second connecting rod 21 adopts a solid round rod, and the third connecting rod 23 adopts a hollow round tube, which not only ensures the strength of the structure but also reduces the overall weight.

[0035] The adjustable device for the notch of the precast beam provided in this embodiment can be used by first sleeveing ​​one end of the fastener 3 on the second connecting rod 21 of the second clamp 2, so that the fastener 3 abuts against the baffle 22, and then the adjusting member 13 is threadedly sleeved on the first connecting rod 12 of the first clamp 1, and the other end of the fastener 3 is also threadedly connected to the first connecting rod 12, and then the fastener 3 is screwed to adjust the length of the entire device, so that the first support 11 of the first clamp 1 and the second support 24 of the second clamp respectively abut against the two opposite sides of the notch of the precast beam, which can adapt to the reinforcement of notches of different widths of precast beams.

[0036] The adjustable device for the notch of the prefabricated beam provided in this embodiment can conveniently adjust the overall length of the device by adjusting the position of the fastener 3 on the first clamp 1, so that it is suitable for notches of different widths of the prefabricated beam, and has strong applicability. The position of the fastener 3 can be further fixed by the provided adjusting member 13, which provides double protection for the device and increases its safety in use. When the device needs to be disassembled, it only needs to be rotated in the reverse direction to tighten the steel pipe, which is convenient and quick to operate, and the device can be reused repeatedly, thereby improving work efficiency.

[0037] The adjustable device for the notch of the precast beam provided in this embodiment is applied to the notch of the precast beam, and its schematic diagram is shown in FIG. Figure 3-Figure 5. First, measure the width of the notch 4 of the prefabricated beam 5 to determine the adjustment range of the fastener 3. Before hoisting the prefabricated beam 5 with the line 6, place the device at the center of the notch 4, and rotate the fastener 3 to tightly fix its two first supports 11 and second supports 24 on the steel side molds 7 on both sides of the notch 4, and rotate the adjusting member 13 to tightly clamp the end of the fastener 3 to increase the safety of the device. Subsequently, the prefabricated beam 5 is hoisted. During disassembly, first rotate the adjusting member 13, and then rotate the fastener 3 in the opposite direction to separate the second clamp 2 from the fastener 3, and then take out the second clamp 2, the first clamp 1, etc. in turn. The device can be reused.
