Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 4, an embodiment of the present invention provides a reusable raft reinforcing bar support, which is composed of support members, cross bars, and hooks disposed on the cross bars.

The supporting member is a linear strip-shaped structure, and in order to ensure the supporting stability and the structural strength of the supporting member, the supporting member in this embodiment may adopt angle steel 1. The surface of the angle steel 1 close to the upper end is provided with a cross rod, and the cross rod is vertically arranged on the angle steel 1. In order to enable the supporting piece and the cross rod to be of a detachable structure, a threaded hole is formed in the surface of the angle steel 1, and the cross rod is detachably arranged in the threaded hole. Preferably, the cross rod adopts a screw rod 2, the screw rod 2 is connected to the angle steel 1 through threads, and a screw rod fixing nut 6 is further arranged on the screw rod 2 and fixed with the angle steel 1.

The screw rod 2 is provided with a hook 3, and the hook 3 is detachably connected with the screw rod 2. Specifically, one end of the hook 3 is a fixing part connected with the screw rod 2, the other end of the hook is a hook part, the fixing part of the hook 3 is detachably sleeved on the screw rod 2, the fixing part of the hook 3 can be set to be an annular structure for being sleeved on the screw rod 2, and the fixing part of the hook 3 can also be set to be U-shaped to be hung on the screw rod 2. The hook part of the hook 3 extends to the lower part of the screw rod 2 and is used for hooking the raft plate reinforcing steel bars 8. Like this, angle steel 1 bottom sprag is on the bottom raft, and the hook portion of couple 3 hooks upper raft reinforcing bar 8, plays stable support to whole raft.

In this embodiment, the screw is provided with a fixing member for fixing the hook 3. The mounting is for two couple fixation nuts 4 of cover on screw rod 2, and two couple fixation nuts 4 set up respectively in the both sides of couple 3 fixed part, carry out the centre gripping to couple 3 fixedly. Further, the fixing piece also comprises a gasket 5, and the gasket 5 is arranged between the fixing part of the hook 3 and the hook fixing nut 4. Two couple fixation nuts 4 play the fixed action to the displacement of couple 3 on screw rod 2 is horizontal, can improve the support stability to hooking raft reinforcing bar 8.

As shown in fig. 4, during use, at least two raft steel bar supports are arranged on the same raft steel bar 8 to be supported, so that the raft steel bars 8 are supported and balanced. Raft reinforcing bar 8 level is placed in couple 3, and at this moment, raft reinforcing bar 8 is hung to couple 3, and raft reinforcing bar 8 remains the distance more than 7cm with the screw rod 2 of top at least, and the distance about 7cm is exactly the thickness of upper muscle and concrete protection layer. When concrete 9 is poured, the lower ends of the angle steels 1 and the hook parts of the hooks 3 are buried in the concrete 9, and the concrete 9 is poured to a position about 7cm above the raft plate reinforcing steel bars 8, so that the upper ends of the angle steels 1, the screws 2 and the fixing parts of the hooks 3 are located outside the concrete 9. When concrete 9 is initially set (about 3 hours), raft steel bar support is completely taken out, and fine aggregate concrete or high-grade cement mortar can be poured back into the holes left in concrete 9.

In this embodiment, the support member is arranged in a linear strip structure, so as to be conveniently drawn out from the initially set concrete 9, and therefore, the angle steel 1 is adopted, and naturally, the angle steel 1 can also be replaced by the square steel 7, as shown in fig. 3, the screw rod 2 transversely penetrates through two opposite sides of the square steel 7, so that a more stable effect can be achieved, the screw rod is also conveniently drawn out from the initially set concrete 9, and only the reserved cavity is large. Similarly, the supporting member may be a circular tube or other shapes, so that the shape of the supporting member may be determined according to actual conditions. Hook 3 can be dismantled also be the taking out of the raft reinforcing bar support of being convenient for with screw rod 2 in this embodiment, can make hook 3 and screw rod 2 separation through couple fixation nut 4 to take out it respectively.

From above, this raft steel bar support can be easily taken out from the concrete 9 of initial set, has realized raft steel bar support's reuse, has avoided traditional steel bar support to bury and has caused the extravagant problem of material in concrete 9, has also solved traditional structure steel bar support and has buried the difficult problem of taking out in concrete 9 because of the structure restriction, and effective save material practicality is strong.

The installation and construction steps of the reusable raft plate steel bar support provided by the embodiment of the utility model are as follows:

(1) after the steel bars are bound, arranging a threaded hole in the surface of one end of the angle steel 1;

(2) inserting one end of the screw rod 2 into a threaded hole drilled in advance, and fixing the screw rod 2 at one end of the threaded hole on the angle steel 1 by using a screw rod fixing nut 6;

(3) the screw rod 2 is provided with a hook 3, the hook 3 hooks raft reinforcing steel bars 8 to be supported, and the height of the raft reinforcing steel bars 8 is determined;

(4) and pass the screw rod 2 in the reinforcing bar middle space, sheathe gasket 5 in one side of raft reinforcing bar 8, use couple fixation nut 4 to fasten, prevent 8 lateral shifting of raft reinforcing bar.

(5) Pouring concrete 9 to embed the lower ends of the angle steels 1 and the hook parts of the hooks 3 in the concrete 9, pouring the concrete to about 7cm above the raft plate steel bars 8, and enabling the upper ends of the angle steels 1, the screw rods 2 and the fixing parts of the hooks 3 to be positioned outside the concrete 9

(6) And after the concrete 9 is poured, loosening the hook fixing nut 4 and the screw fixing nut 6 after initial setting and before final setting (about 3 hours), taking all materials out of the concrete 9, removing formed holes, and filling the holes with high-grade waterproof cement mortar.

The whole process has few steps and flows, is simple to operate, effectively saves energy of supporting materials when the raft steel bar support plays a role in stable support, reduces the cost of construction materials, and has very high practical value.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
