[0021] In the following, only some exemplary embodiments are briefly described to make the purpose, features and advantages of the utility model more obvious and understandable. As those skilled in the art will appreciate, the described embodiments can be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0022] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] like Figures 1 to 3 As shown, the utility model provides a double steel pipe fixing device for the bottom of a formwork frame beam, comprising: a fixing mechanism 1; a U-shaped steel plate 2 for fixing double steel pipes 5 is arranged at the upper end of the fixing mechanism 1; an anti-slip fastener 3; the anti-slip fastener 3 is arranged on one side of the fixing mechanism 1; a locking mechanism 4; one end of the locking mechanism 4 is movably arranged on the fixing mechanism 1, and the other end of the locking mechanism 4 is detachably connected to the anti-slip fastener 3.

[0024] In this embodiment, there are two U-shaped steel plates 2, which are respectively arranged on both sides of the upper end of the fixing mechanism 1. The U-shaped steel plate 2 and the fixing mechanism 1 can be a prefabricated integrated structure or a split structure, and nuts or buckles are used to combine and fix the components; the length of the U-shaped steel plate 2 can be customized according to the design plan so that it can adapt to double steel pipes or multiple steel pipes;

[0025] When the fixing device is used, the fixing mechanism 1 is installed on the side upright 6 of the formwork frame beam, and is locked and fixed by the cooperation relationship between the anti-slip fastener 3 and the clamping assembly 4, so that the fixing device is in a closed state (see Figure 1 and Figure 3 ), the U-shaped steel plates 2 on both sides of the upper end of the fixing mechanism 1 can fix and support the double steel pipes 5, so that the double steel pipes 5 and the beam side uprights 6 are connected as a whole, thereby achieving a fixing effect between the beam side uprights 6 and the double steel pipes 5, thereby forming a stable support system and reducing safety risks during use.

[0026] Furthermore, the fixing mechanism 1 includes: a first fixing member 11 and a second fixing member 12; the first fixing member 11 and the second fixing member 12 are rotatably connected; the U-shaped steel plate 2 is respectively arranged on the upper ends of the first fixing member 11 and the second fixing member 12; the anti-slip fastener 3 is arranged on one side of the first fixing member 11; and the locking mechanism 4 is movably arranged on the second fixing member 12.

[0027] In this embodiment, the fixing mechanism 1 includes a first fixing member 11 and a second fixing member 12 symmetrically arranged on both sides, and the two fixing members are connected and can rotate relative to each other. When the fixing member 1 is rotated to different angles, the fixing mechanism 1 is in a closed state and an open state (see Figure 1 and Figure 2 );

[0028] Two U-shaped steel plates 2 are respectively arranged at the upper ends of the first fixing member 11 and the second fixing member 12; the anti-slip fastener 3 is arranged on the first fixing member 11, and the locking mechanism 4 is arranged on the second fixing member 12. When the fixing mechanism 1 is in an open state, the anti-slip fastener 3 is separated from the locking mechanism 4, and when the fixing mechanism 1 is in a closed state, the anti-slip fastener 3 and the locking mechanism 4 are abutted and locked with each other.

[0029] Furthermore, the first fixing member 11 has a first mounting groove 13 corresponding to the side upright 6 of the formwork frame beam, and the second fixing member 12 has a second mounting groove 14 corresponding to the first mounting groove 13. Both the first mounting groove 13 and the second mounting groove 14 are arc-shaped grooves.

[0030] In this embodiment, the inner side of the first fixing member 11 has a first mounting groove 13, and the inner side of the second fixing member 12 has a second mounting groove 14. The first mounting groove 13 and the second mounting groove 14 are both arc-shaped grooves. Both adopt an arc-shaped groove structure, which corresponds to the shape of the side upright 6 of the formwork frame beam, so that when the first fixing member 11 and the second fixing member 12 are closed, they can be tightly clamped on the beam side upright 6 through the first mounting groove 13 and the second mounting groove 14.

[0031] Furthermore, the locking mechanism 4 includes: a movable rod 41 and a pressing assembly 42 ; the movable rod 41 is rotatably disposed on the second fixing member 12 ; and the pressing assembly 42 is movably disposed on the movable rod 41 .

[0032] In this embodiment, the movable rod 41 is rotatably set on the second fixing member 12, and the clamping assembly 42 is set on the movable rod 41. When the fixing mechanism 1 is in an open state, the movable rod 41 and the anti-slip fastener 3 are separated from each other. When the fixing mechanism 1 is in a closed state, the movable rod 41 rotates to one side of the anti-slip fastener 3, and the clamping assembly 42 and the anti-slip fastener 3 are pressed against each other, so that the first fixing member 11 and the second fixing member 12 are fixed and no longer rotate.

[0033] Furthermore, a positioning groove 31 capable of accommodating the movable rod 41 is provided on the anti-slip fastener 3 .

[0034] In this embodiment, the positioning groove 31 is provided on the anti-slip fastener 3, and the positioning groove 31 can accommodate the movable rod 41. When the fixing mechanism 1 is in the closed state, the movable rod 41 rotates into the positioning groove 31, and the pressing component 42 and the outer side of the anti-slip fastener 3 are pressed against each other (see Figure 1 ), thereby achieving a locking effect on the fixing mechanism 1 after closing.

[0035] Further, the movable rod 41 is a stud. The pressing assembly 42 comprises: a nut and a washer corresponding to the nut; the nut is threadedly connected to the stud; and the washer is movably arranged on the stud.

[0036] In this embodiment, the movable rod 41 can adopt a stud structure, and the clamping assembly 4 is composed of a nut and a corresponding gasket. The nut is threadedly connected to the stud. When the fixing mechanism 1 is in a closed state, the stud is rotated into the positioning groove 31, and the nut is manually controlled so that the nut and the anti-slip fastener 3 are pressed against each other through the gasket, thereby achieving a locking effect after the fixing mechanism 1 is closed, and the operation is simple and convenient.

[0037] Furthermore, a right-angle portion is provided on the U-shaped steel plate 2 .

[0038] In this embodiment, a right-angle portion is provided on the outer side of the U-shaped steel plate 2 , and the right-angle portion makes the U-shaped steel plate 2 more stable when supporting the double steel pipes, thereby preventing the steel pipes from detaching from the U-shaped steel plate 2 .

[0039] The utility model provides a double steel pipe fixing device for the bottom of a formwork frame beam. The functions of each module in each device of the embodiment can be referred to the corresponding description in the above method. It has the advantage of being able to fix the beam side uprights and the double steel pipes to form a stable support system.
