Description

Technical Field

[0001] The utility model relates to the field of the construction industry, in particular to a prefabricated steel structure cable-supported beam support falsework. Background Art

[0002] A cable-supported beam is a building component with a simple structure and uniform stress, and its rigid and flexible properties are stable, which can be used for people to build houses. In order to avoid the rust of the falsework, steel is needed to make the falsework. When it exists as a support component, a ladder needs to be assembled inside the frame for the convenience of workers to go up and down.

[0003] With the increase of the building height, the support falsework used for the cable-supported beam often rises accordingly. Prefabricated falsework needs to be used and assembled one by one for support. However, the column spacing around the previous such falsework is fixed, and the size specification and support range of the falsework cannot be changed according to the temporary construction requirements. Summary of the Invention

A moving block 17 is installed at the center of the side surface of the hinge seat 6. A gear 18 matching the rack 19 is arranged on the side surface of the moving block 17. A positioning piece 21 is further installed on the surface of the hinge seat 6. A second bolt 20 is threadedly connected inside the positioning piece 21 to fix the moved hinge seat 6 on the inner wall of the slideway 16 through the second bolt 20. An inclined rod 5 is connected to the outer end of the hinge seat 6. A sleeve 7 is sleeved on the outer end of the inclined rod 5. A support rod 8 is horizontally connected between the centers of the foundation frame body 1 and the splicing frame body 10. The sleeve 7 is hingedly connected to the support rod 8 through a connecting piece 12. Threaded telescopic rods 28 are connected to both ends of the support rod 8. The threaded telescopic rods 28 are fixedly connected to the columns of the foundation frame body 1 and the columns 30 of the splicing frame body 10 through connecting bolts 29. The ladder 3 is welded to the support rod 8.

[0048] In this embodiment, after the base frame 1 and the splicing frame 10 are assembled together, when it is necessary to adjust the sizes of the base frame 1 and the splicing frame 10 to meet different requirements. First, loosen the connecting bolt 29 to separate the threaded telescopic rod 28 from the columns 30 of the base frame 1 and the columns 30 of the splicing frame 10. Then, by moving the hinge seat 6 at the end of the inclined rod 5, the moving block 17 installed outside the hinge seat 6 moves up and down along the rack 19 on the inner wall of the slideway 16 through the gear 18, so as to adjust the position of the hinge seat 6. Under the action of the inclined rod 5, the columns 30 of the base frame 1 and the splicing frame 10 are pushed outward. When it moves to a suitable position, stop moving the hinge seat 6, and use the second bolt 20 outside the positioning piece 21 to fix the entire moving block 17 inside the slideway 16, thereby fixing the inclined rod 5. Then, according to the gap between adjacent columns in the base frame 1 and the splicing frame 10, adjust the length of the threaded telescopic rod 28 to a suitable position, and use the connecting bolt 29 to fix the outer end of the threaded telescopic rod 28 to the column 30, so as to ensure the stability of the entire structure after the size adjustment of the base frame 1 and the splicing frame 10, and make the use more flexible and safe.

[0049] In some embodiments, insertion rods 23 are connected to the corners at the bottom ends of the columns 30 of the splicing frame 10, connection grooves 9 are provided at the corners at the top ends of the columns 30 of the base frame 1, silica gel sleeves 22 matching the insertion rods 23 are arranged inside the connection grooves 9, and pins 13 located outside the top ends of the insertion rods 23 are further installed at the bottom ends of the corners of the splicing frame 10. A retaining sleeve 14 is fixedly installed at the top ends of the corners of the base frame 1. The pin 13 is inserted into the retaining sleeve 14, and a first bolt 15 is threadedly connected to the retaining sleeve 14 to fix the pin 13 and the retaining sleeve 14 through the first bolt 15.

[0050] During the splicing and assembly process of the splicing frame 10 and the base frame 1, first insert the insertion rods 23 at the bottom ends of the four columns 30 of the splicing frame 10 into the connection grooves 9 at the top ends of the columns 30 of the base frame 1, so that the insertion rods 23 and the silica gel sleeves 22 inside the connection grooves 9 are inserted and fixed together. Then, fix the pins 13 at the bottom ends of the corners of the columns 30 of the splicing frame 10 on the retaining sleeve 14, and fix the pin 13 and the retaining sleeve 14 together through the first bolt 15 to ensure the stability after the splicing frame 10 and the base frame 1 are assembled.

[0051] In still other embodiments, the ladder 3 includes two vertical rods 27, and a plurality of cross rods 4 are horizontally welded between the two vertical rods 27 at equal intervals. A plurality of limiting grooves 26 are uniformly arranged on the surface of the vertical rod 27. A handle 11 is inserted into the limiting groove 26. A clamping block 25 is welded to the side surface of the handle 11. The handle 11 slides along the limiting groove 26 through the clamping block 25, and the clamping block 25 is fixedly connected to the limiting groove 26 through a third bolt 24.

[0052] In this embodiment, horizontally welding a plurality of cross rods 4 between the vertical rods 27 of the ladder 3 facilitates workers to go up and down, and the handle 11 is convenient for workers to grasp when using the ladder 3. And since the handle 11 slides along the limiting groove 26 through the clamping block 25 and is fixed by the third bolt 24, the position of the sliding block 25 inside the limiting groove 26 can be adjusted according to actual needs. After adjustment, the clamping block 25 is fixed inside the limiting groove 26 through the third bolt 24, so as to adjust the position of each handle 11 on the vertical rod 27, which is convenient for use.

[0053] In some embodiments, a bottom pad 2 is installed at the bottom end of the base frame 1, which plays a role in supporting and protecting the base frame 1 and enhances the stability of the whole device.

[0054] The assembled steel structure cable-supported beam support falsework of the present invention is provided with a base frame and a splicing frame spliced up and down, which is convenient for realizing horizontal assembly. And since both the base frame and the splicing frame are connected with inclined rods through hinge seats, and the inclined rods are connected inside the sleeves, according to the sizes that need to be adjusted for the base frame and the splicing frame, the hinge seats connected to the inclined rods are pushed to slide up and down inside the slideway. The hinge seats slide up and down along the rack on the inner wall of the slideway under the action of the gears, so as to adjust the distance between the columns of the base frame and the splicing frame. After determining that the distance between the columns of the base frame and the splicing frame has been adjusted, the hinge seats are fixed on the inner wall of the slideway through the second bolts. And after stretching the threaded telescopic rod on the outer wall of the tension support rod to an appropriate length, the outer end of the threaded telescopic rod is fixed on the columns of the base frame and the splicing frame through the connecting bolts, so as to realize the size adjustment of the base frame and the splicing frame, which can meet different usage requirements and is more flexible to use.
