DETAILED DESCRIPTION

[0024] The technical solutions of the present application will be described clearly and completely in combination with the embodiments. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative effort are within the scope of the present application.

[0025] Referring to Figures 1-5 , the present application provides a technical solution:

[0026] Embodiments:

[0027] As Figures 1-5 shown, a pavement pouring formwork with a force transmission rod support frame comprises a formwork body 1, a support frame 2 and a force transmission rod 3, the support frame 2 is a right-angled trapezoidal structure, the support frame 2 is used for supporting the formwork body 1, the formwork body 1 is provided with a first through hole 4 for mounting the force transmission rod 3, and further comprises a horizontal support rod 6, the horizontal support rod 6 is provided with a second through hole 7 coaxial with the first through hole 4, and the force transmission rod 3 extends into the first through hole 4 through the second through hole 7.

[0028] Among them, the support frame 2 is welded by four profile steels, one long and one short vertical parallel profile steels are arranged, one horizontal profile steel is arranged between the two vertical profile steels, and the last profile steel is arranged at the top end of the two vertical profile steels.

[0029] The horizontal support rod 6 is supported by at least two height-adjustable support frames 11.

[0030] The outer side of the support frame 2 is provided with a vertical fixing sleeve 8, the fixing sleeve 8 is provided with a steel drill 9, and a wedge block 10 is arranged between the steel drill 9 and the support frame 2.

[0031] The wedge block 10 is made of wooden material. The wooden material can be but is not limited to bamboo wood and raw wood.

[0032] The horizontal support rod 6 is a square steel.

[0033] As Figures 3-5 shown, the support frame 11 comprises a support circular pipe 12, a support screw rod 13, a support screw sleeve 16 and a support ring plate 14, the bottom end of the support circular pipe 12 is provided with a base 15, and the top end of the circular pipe is open;

[0034] The support ring plate 14 is arranged outside the support screw sleeve 16, the size of the support ring plate 14 is greater than the inner diameter of the support circular pipe 12, the support screw sleeve 16 is threadedly connected outside the support screw rod 13, the bottom end of the support screw rod 13 extends into the support circular pipe 12, and the top end of the support screw rod 13 is fixedly connected with a limiting support plate 5.

[0035] The limiting support plate 5 is used for supporting the horizontal support rod 6 and limiting the axial displacement of the horizontal support rod 6 along the second through hole 7.

[0036] The limiting support plate 5 is a C-shaped steel.

[0037] The base 15 is welded with the support circular pipe 12 as a whole, and the support ring plate 14 is welded with the support screw sleeve 16 as a whole.

[0038] When the formwork is erected, a row of fixed holes corresponding to the upper and lower fixed sleeves 8 is first drilled along the length direction of the formwork, and the fixed holes are arranged at equal intervals. Then the steel drill 9 is inserted into the fixed hole from the fixed sleeve 8, and since the inner diameter of the fixed sleeve 8 is larger than the outer diameter of the steel drill 9, the formwork will be displaced in the horizontal direction. At this time, the wedge-shaped block 10 is clamped between the support 2 and the steel drill 9, and in this process, the wedge-shaped block 10 is downwardly extruded on the steel drill 9, the steel drill 9 is inclined, the vertical surface of the wedge-shaped block 10 is attached to the vertical surface of the support 2, and when the wedge-shaped block 10 cannot continue to go down, the steel formwork is fixed.

[0039] Then the horizontal support rod 6 is horizontally inserted into the trapezoidal hole of the support 2, the horizontal support rod 6 is lifted to keep the second through hole 7 coaxial with the first through hole 4, and at this time, the support frame 11 is installed at the bottom of the horizontal support rod 6, so that the fixation of the horizontal support rod 6 is completed.

[0040] Then the force transmission rod 3 is inserted into the first through hole 4 from the second through hole 7 of the horizontal support rod 6, so that the erection of the formwork is completed. Since the force transmission rod 3 is limited by the first through hole 4 and the second through hole 7, the axial displacement of the force transmission rod 3 will not occur.

[0041] The height of the support frame 11 is adjustable, so that it can be applied to formworks with different heights of the first through hole 4. The height adjustment process of the support frame 11 is that the support screw sleeve 16 is rotated, the support screw sleeve 16 is raised / lowered along the support screw rod 13, so that the length of the support screw rod 13 entering the support circular pipe 12 at the bottom is increased / decreased, and then the lifting / lowering of the limiting support plate 5 is realized. When the support frame 11 is used, the limiting support plate 5 can limit the axial displacement of the horizontal support rod 6 along the second through hole 7.

[0042] The utility model discloses a force transmission rod support frame can provide support for the force transmission rod, and the axial displacement of the force transmission rod during construction can be avoided.

[0043] The above merely describes preferred embodiments of the present application, and it should be understood that the present application is not limited to the forms disclosed herein, and should not be considered as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concepts described herein, by the above teachings or related art or knowledge. Any modification and change made by those skilled in the art without departing from the spirit and scope of the present application shall be within the protection scope of the claims of the present application.
