[0037] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0038] Please refer to Figure 1 and Figure 4, the present invention provides an adjustable support device for a floor pouring formwork, including an adjustable cross bar and two vertical rods 1. Discs 2 are fixedly installed on the outer walls of the two vertical rods 1, and the vertical rods 1 penetrate through the discs 2. The adjustable cross bar includes an adjusting screw rod 6. Sleeve steel pipes 7 are threadedly connected to both ends of the adjusting screw rod 6. The sleeve steel pipes 7 are connected to the discs 2. The interior of the sleeve steel pipes 7 is a hollow structure. Threads 14 matching the adjusting screw rod 6 are provided on the inner walls of the sleeve steel pipes 7. Anti-loosening heads 12 are installed at both ends of the adjusting screw rod 6. Screw holes 8 are provided at the tops of the anti-loosening heads 12. Two rows of rack teeth 13 are provided on the outer walls of the sleeve steel pipes 7. An activity groove 9 is provided between the two rows of rack teeth 13. A tooth gasket 10 is installed on the surface of the sleeve steel pipes 7. The bottom of the tooth gasket 10 meshes with the rack teeth 13. A locking nut 4 is installed on the tooth gasket 10. The bottom end of the locking nut 4 penetrates through the tooth gasket 10 and inserts into the screw hole 8 inside, and the locking nut 4 is fixed by meshing the tooth gasket 10 with the rack teeth 13.

[0039] In this embodiment, when it is necessary to fix the pouring formwork of a building floor, the entire adjustable device is placed between two formworks to be supported. The adjusting screw rod 6 is rotated according to the required length. Since both ends of the adjusting screw rod 6 are threadedly connected to the inner walls of the sleeve steel pipes 7, the length of the adjusting screw rod 6 inside the sleeve steel pipes 7 changes, so as to facilitate adjusting the length of the entire adjustable cross bar. After the adjusting screw rod 6 is rotated to a suitable position, the locking nut 4 is inserted into the activity groove 9 between the two rows of rack teeth 13, so that the bottom end of the locking nut 4 is inserted into the screw hole 8 on the anti-loosening head 12. At the same time, the tooth gasket 10 is meshed with the rack teeth 13, so that the locking nut 4 will not move randomly inside the activity groove 9, ensuring the stability of the adjusting screw rod 6 after adjustment. Thus, after adjusting the length of the entire device, the sleeve steel pipes 7 at both ends of the adjusting screw rod 6 can be fixed between the floor formworks to support the floor formworks, ensuring the safety and stability of the pouring process.

[0040] In some embodiments, the thread rotation directions on both sides of the center position of the adjusting screw rod 6 are opposite, so that the adjusting screw rod 6 moves in opposite directions when rotating to achieve synchronous retraction or extension of the sleeve steel pipes 7.

[0041] Specifically, since the threads of the adjusting screw rod 6 are divided into positive and negative threads in the middle position, that is, one is a positive thread and the other is a reverse thread, when the adjusting screw rod 6 rotates in the same direction, the two ends of the adjusting screw rod 6 can move in opposite directions inside the sleeve steel pipes 7. The ends of the adjusting screw rod 6 simultaneously extend into the sleeve steel pipes 7 or simultaneously extend out of the sleeve steel pipes 7, so as to conveniently adjust the length of the adjusting screw rod 6 inside the sleeve steel pipes 7, thereby adjusting the length of the entire adjustable cross bar, which is more convenient to use.

[0042] In some other embodiments, a handle 5 is installed at the middle position of the adjusting screw rod 6, and the handle 5 is used to rotate the adjusting screw rod 6, making the operation more convenient.

[0043] Specifically, the handle 5 is installed at the middle position of the adjusting screw rod 6. The thread of the adjusting screw rod 6 on one side of the handle 5 is in the clockwise direction, and the thread of the adjusting screw rod 6 on the other side of the handle 5 is in the counterclockwise direction, so as to facilitate the adjustment of the adjusting screw rod 6.

[0044] Furthermore, a first opening 15 is provided on the disc 2. One end of the sleeve steel pipe 7 far from the adjusting screw rod 6 is connected with a support seat 16. A second opening 11 corresponding to the position of the first opening 15 is provided on the support seat 16. An insertion port 17 matching the disc 2 is provided outside the support seat 16. A pin 3 is movably inserted into the support seat 16. The pin 3 is sequentially inserted into the support seat 16 and the disc 2 to fixedly install the sleeve steel pipe 7 on the disc 2.

[0045] In order to fix the adjusting screw rod 6 after adjusting the length, the insertion port 17 of the support seat 16 connected to the sleeve steel pipes 7 at both ends is docked with the disc 2 to preliminarily fix the disc 2 on the support seat 16. Then, the pin 3 is sequentially inserted into the second opening 11 of the support seat 16 and the first opening 15 of the disc 2, so as to fix the support seat 16 and the disc 2 together through the pin 3, thereby fixing the entire adjustable cross bar on the vertical rod 1. Since the vertical rod 1 is fixedly connected to the disc 2, the entire adjustable cross bar can be fixed to the vertical rod 1, so as to stably support the formwork.

[0046] Furthermore, the outer end of the support seat 16 fits with the surface of the vertical rod 1 to ensure close contact and is not prone to deviation. And the vertical rod 1 and the disc 2 are perpendicularly connected.

[0047] When the adjustable support device of the floor slab casting formwork of the present invention is in use, according to the required length, the adjusting screw rod is rotated, so that the adjusting screw rod rotates in the sleeve steel pipe, thereby changing the length of the adjusting screw rod in the sleeve steel pipe, and thus adjusting the length of the entire adjustable cross bar. After adjusting the length of the adjustable cross bar, the lock nut is fixed through the tooth gasket and the rack, so as to ensure the stability of the adjustable cross bar after length adjustment. Then, both ends of the entire adjustable cross bar are respectively fixed on the discs of the vertical rods, and the formwork can be supported by using the vertical rods at both ends. It is more convenient to use under the condition of ensuring the use strength and can meet the support use requirements of different lengths.

[0048] The present invention also provides a support method for the adjustable support device of the floor slab casting formwork, which is applied to the adjustable support device of the floor slab casting formwork as described above. Refer to Figure 5, the support method includes the following steps:

[0049] S100. Measure the erection spacing of the floor formwork to be supported;

[0050] S200. Place the adjustable support device of the floor casting formwork between the floor formworks, and according to the erection spacing, rotate the adjusting screw so that the adjusting screw rotates along the inner walls of the sleeve steel pipes at both ends until the adjusting screw rotates to the corresponding position, and then fix it with a locking nut;

[0051] S300. Insert a pin into the disc to fix the support base at the outer end of the sleeve steel pipe on the vertical rod, so as to fixedly support the formwork.

[0052] Specifically, in this embodiment, when it is necessary to fix the casting formwork of the building floor, place the entire adjustable device between the two formworks to be supported, and rotate the adjusting screw 6 according to the required length. Since both ends of the adjusting screw 6 are threadedly connected to the inner walls of the sleeve steel pipes 7, the length of the adjusting screw 6 inside the sleeve steel pipes 7 changes, so as to facilitate the adjustment of the length of the entire adjustable cross bar. After the adjusting screw 6 rotates to a suitable position, insert a locking nut 4 into the movable slot 9 between the two racks 13, so that the bottom end of the locking nut 4 is inserted into the screw hole 8 on the anti-disengagement head 12, and at the same time, the tooth washer 10 is engaged with the rack 13, so that the locking nut 4 will not move randomly inside the movable slot 9, ensuring the stability of the adjusting screw 6 after adjustment. In order to fix the adjusting screw 6 after adjusting the length, dock the socket 17 of the support base 16 connected to the sleeve steel pipes 7 at both ends with the disc 2 to initially fix the disc 2 on the support base 16, and then insert the pin 3 into the second opening 11 of the support base 16 and the first opening 15 of the disc 2 in sequence, so as to fix the support base 16 and the disc 2 together through the pin 3, thereby fixing the entire adjustable cross bar on the vertical rod 1. Since the vertical rod 1 is fixedly connected to the disc 2, the entire adjustable cross bar can be fixed to the vertical rod 1, so as to stably support the formwork, so that after adjusting the length of the entire device, the sleeve steel pipes 7 at both ends of the adjusting screw 6 can be fixed between the floor formworks to support the floor formwork, ensuring the safety and stability of the casting process.

[0053] The above are only the preferred embodiments of the present invention, and are not used to limit the protection scope of the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
