[0031] Example

[0032] When casting a frame beam, a casting space with an upper opening is usually formed by setting a beam side formwork 100 and a beam lower formwork 200, and concrete is cast into the casting space through the upper opening to form a beam.

[0033] Reference Figure 1-2 As shown, the utility model provides a beam side formwork reinforcement device, comprising a first square tube 1, a second square tube 2, two telescopic tubes 3 and a plurality of tension bolts 4;

[0034] The second square tube 2 is movably sleeved in the first square tube 1 ; two telescopic tubes 3 are respectively fixed on the same side of the first square tube 1 and the second square tube 2 , and a plurality of through holes 33 are opened on the telescopic tubes 3 ; and the tension bolts 4 are respectively penetrated in the through holes 33 .

[0035] The device has a "door"-shaped overall structure. The second square tube 2 is movably sleeved in the first square tube 1. The overall length of the first square tube 1 and the second square tube 2 is adjustable, and the lengths of the two telescopic tubes 3 themselves can also be adjusted. After the template is supported, the device is sleeved outside the template. The overall lengths of the first square tube 1 and the second square tube 2 are adjusted according to the width of the lower side template 200 of the beam. The length of the telescopic tube 3 is adjusted according to the length of the side template 100 of the beam, so that the first square tube 1 and the second square tube 2 support the reinforcement wood outside the lower side template 200 of the beam, and the two telescopic tubes 3 support the reinforcement wood outside the side template 100 of the beam. Then, the tension bolts 4 are passed through the through holes 33 on the telescopic tubes 3 to tighten and fix the two telescopic tubes 3 to complete the reinforcement of the beam side template.

[0036] The utility model has an integral structure and is easy to operate. The overall length of the first square tube 1 and the second square tube 2 and the length of the two telescopic tubes 3 can be adjusted. It can be used to reinforce beam side formworks of different widths and lengths. It has strong applicability and can save construction costs.

[0037] In a specific embodiment, the two telescopic tubes 3 are respectively fixed to ends of the first square tube 1 and the second square tube 2 that are away from each other.

[0038] In a specific embodiment, the telescopic tube 3 includes a third square tube 31 and a fourth square tube 32; the third square tube 31 is fixedly connected to the first square tube 1 or the second square tube 2; the fourth square tube 32 is movably sleeved in the third square tube 31; both the third square tube 31 and the fourth square tube 32 are provided with a through hole 33, and the fourth square tube 32 can be pulled out from the third square tube 31, and the overall length of the telescopic tube 3 can be adjusted by different pulling lengths.

[0039] In a specific embodiment, it also includes a head plate 5, a first nut 6, a screw 7 and a second nut 8; the head plate 5 is fixed to the end of the first square tube 1 away from the second square tube 2; the first nut 6 is fixed in the second square tube 2; the screw 7 is rotatably installed in the first square tube 1, one end of which is threadedly connected to the first nut 6, and the other end passes through the outside of the head plate 5; the second nut 8 is fixed to the end of the screw 7 that passes through the head plate 5.

[0040] The first square tube 1 and the second square tube 2 cooperate with each other and cannot rotate with each other. After screwing the second nut 8, the screw rod 7 can be driven to rotate clockwise and counterclockwise, thereby driving the second square tube 2 to approach or move away from the first square tube 1, thereby adjusting the distance between the two telescopic tubes 3.

[0041] In a specific embodiment, the first nut 6 is fixed to one end of the second square tube 2 close to the first square tube 1, so that the first square tube 1 and the second square tube 2 can obtain the maximum adjustable length.

[0042] In a specific implementation manner, a gasket 9 is provided between the head plate 5 and the second nut 8 to isolate the head plate 5 from the second nut 8 to avoid mutual friction and play a buffering role.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
