Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

With reference to accompanying drawings 2 to 4, a beam jacking for construction includes a plug 1 and a threaded rod 4, the upper end of the threaded rod 4 is fixedly connected with the top 1, and an adjusting nut 5 is screwed on the threaded rod 4. It also includes a wooden square 3 and a connecting buckle 10, the top 1 is provided with a groove 2, the wooden square 3 is installed in the groove 2, and the first nail holes 8 are respectively provided on both sides of the groove 2 and the set screw 9, the first nail hole 8 and the set screw 9 all penetrate from the top 1 to the groove 2; the two ends of the wooden frame 3 are respectively connected with a slanting block 12, and the two slanting blocks 12 below each rotate A diagonal strut 11 is connected, and the lower ends of the two diagonal struts 11 are rotatably connected to the connecting buckle 10; the lower end of the threaded rod 4 is also connected with the limited pendulum block 7 .

After adopting the above-mentioned structure, the utility model has the following beneficial effects: wooden beams are installed on the jacking bracket, and when the formwork is installed, the beam bottom plate and the wooden beams can be directly fixed by iron nails, and there will be no relative movement between the two. Moreover, there are two flat surfaces in contact between the wooden beam and the beam bottom plate, and it is more stable when placing the beam bottom plate. In addition, the two ends of the wooden beams are provided with diagonal bracing structures, and the connecting buckle at the lower end of the diagonal bracing rods can be locked on the outer ring of the steel pipe inserted by the threaded rods. The wooden beams supported by this diagonal bracing structure are very stable, no need Then erect steel pipe supports at both ends of the wooden beams, saving a lot of steel pipes.

The swing limiting block 7 is detachably connected with the threaded rod 4 . The detachable connection makes the maintenance and installation of the whole product more flexible and convenient. At the same time, the swing limiting block can be quickly replaced according to steel pipes of different calibers. Described pendulum-limiting block 7 can use rubber block, also can use nut, and its effect is to prevent threaded rod 4 from being inserted into steel pipe 14 and can swing when being subjected to external force.

The adjusting nut 5 is provided with a booster handle 6 . The helper handle structure can help the user to quickly turn the adjustment nut. The first nail holes 8 are two or more, arranged side by side in the horizontal direction on one side of the groove 2, the first nail holes 8 are used to drive in iron nails to fix the plug 1 and the wooden square 3 relative positions. The design of more than two first nail holes can make the wooden beam and the top more firmly connected. The set screws 9 can also be more than two, arranged side by side in the horizontal direction on one side of the groove 2, and the set screws 9 are used to push the wooden beam 3 whose width is smaller than the groove 2 to the first nail hole side of where. Double set screws can better tighten the wooden beam, and the diagonal brace 12 is an angle steel, and the angle steel is provided with a second nail hole 13. There are mature products of angle steel, which can be modified directly, and the production of products is more convenient. The upper end of the diagonal brace 11 is hinged with the diagonal brace 12, and the lower end is hinged with the connecting buckle 10. The connecting buckle 10 can be fixed on the steel pipe 14 by using a hoop or a hoop structure.

Further in conjunction with accompanying drawing 5, when the utility model patent is in specific use, the threaded rod 4 is inserted into the steel pipe 14 used to match the jacking on the construction site, and the pendulum limiting block 7 is inserted together until the adjustment nut The lower end surface of 5 is offset against the upper end surface of steel pipe 14, and then the adjusting nut 5 is rotated to move the top head to a suitable height. The wooden beams are generally matched with the size that can be tightly matched with the groove 2, and the wooden beams are smaller than The size of groove 2, then with set screw 9 wooden frame 3 is pushed to the other side of groove. Then drive an iron nail from the first nail hole to lock the relative position of the wooden beam and the top. Of course, when the size of the wooden beam and the groove is just enough to be clamped, it is also best to drive the iron nail through the first nail hole to make the connection stronger.

When the building beams are molded, a jacking is needed every certain distance, so it is necessary to arrange and install a plurality of jackings in advance, and then lay the beam bottom plate 15 on the arranged wooden beams, and then use nails Directly fix the beam bottom plate 15 and the wooden beam together, and then install the beam side plates 16 on both sides. When the height of the beam side plate 16 is too high, you can directly install the support rod 17 on the outside of the side plate, and the support rod 17 The lower end of the wooden frame can be directly fixed to the wooden frame, which is also the place where the wooden frame structure is more convenient than the steel pipe. Workers can also stand and walk on the wooden frame very conveniently during the molding process. During the production of the construction beam support involved in the utility model, the wooden beams 3 and the diagonal braces 11 all can use waste materials on the construction site, that is, directly recycle relevant materials from the construction site, which is more energy-saving and environmentally friendly.

The utility model and its implementations have been described above, but the description is not restrictive. What is shown in the drawings is only one of the implementations of the utility model, and the actual structure is not limited thereto. All in all, if a person of ordinary skill in the art is inspired by it, without departing from the purpose of the utility model, without creatively designing a structural method and embodiment similar to the technical solution, it shall be protected by the utility model scope.
