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, the embodiment of the present invention provides a reusable steel bar support, which includes a column 1, a sleeve 2, and a support rod 3. Wherein, the upright post 1 is a straight rod, and the sleeve 2 is sleeved on the upright post. In this embodiment, in order to move the sleeve 2 in the extending direction of the column 1, the column 1 is provided as a screw having an external thread on the surface. Meanwhile, a through hole is formed in the sleeve 2, an internal thread matched with the external thread of the stand column 1 is arranged in the through hole, namely the sleeve 2 is arranged into a threaded sleeve, and the sleeve 2 is in threaded connection with the stand column 1, so that the sleeve 2 moves on the stand column 1.

In this embodiment, 2 surfaces of sleeve pipe are equipped with perpendicular to sleeve pipe 2's bracing piece 3, and when stand 1 and sleeve pipe 2 were in vertical state, bracing piece 3 just was in the horizontality, can be used for placing raft reinforcing bar 6 this moment, and bracing piece 3 effectively supports raft reinforcing bar 6. In order to guarantee that raft reinforcing bar 6 is stable in bracing piece 3 position, be equipped with the limit structure who is used for fixed raft reinforcing bar 6 on bracing piece 3. Preferably, the limiting structure is at least two fixing nuts 4 sleeved on the support rod 3. At this moment, bracing piece 3 is the threaded rod, and two fixation nut 4 are located raft reinforcing bar 6's both sides respectively, carry out certain spacing or clamping action to raft reinforcing bar 6, prevent that raft reinforcing bar 6 from removing along 3 horizontal directions of bracing piece.

Of course, the limiting structure may also be a fixing nut 4 sleeved on the support rod 3. As shown in fig. 3, the inclined rod 5 is disposed on the surface of the sleeve 2 above the support rod 3, the inclined rod 5 and the support rod 3 are in the same vertical plane, and the inclined rod 5 and the support rod 3 form an outward-opening included angle. Put into the contained angle that down tube 5 and bracing piece 3 formed with raft board reinforcing bar 6 to 3 bracing pieces through the outside at raft board reinforcing bar set up a fixation nut 4, fixation nut 4 and down tube 5 carry on spacingly to raft board reinforcing bar 6 jointly, play effectual fixed action.

Further, the polished rod can be set to bracing piece 3, and limit structure is two archs of fixed setting at 3 upper surfaces of bracing piece, and two bellied intervals are less than raft reinforcing bar 6's diameter, places raft reinforcing bar 6 between two archs, can realize fixing raft reinforcing bar 6.

In this embodiment, the threaded connection between the upright post 1 and the sleeve 2 can realize effective separation of the upright post and the sleeve, and similarly, the support rod 3 and the sleeve 2 can also be detachably arranged. Specifically, set up the screw hole on the lateral wall of sleeve pipe 2, 3 tip of bracing piece are equipped with the external screw thread, and bracing piece 3 can insert in the screw hole on the lateral wall of sleeve pipe 2 with sleeve pipe 2 threaded connection. Of course, in order to ensure the stable connection between the support rod 3 and the sleeve 2, the support rod 3 and the sleeve 2 may be fixedly connected or may be provided as an integral structure.

During the use, as shown in fig. 4, with vertical being fixed in the base of stand 1 on, place raft reinforcing bar 6 in 3 upper ends of bracing piece, carry out certain horizontal fixed to raft reinforcing bar 6 through fixation nut 4, guarantee raft reinforcing bar 6 stable in position. Simultaneously, can realize reciprocating of sleeve pipe 2 on stand 1 through rotatory sleeve pipe 2, adjust raft board reinforcing bar 6 to appropriate high position, solve the nonadjustable problem of traditional support height. And after the raft plate reinforcing steel bars 6 are installed and fixed, pouring concrete. When pouring, concrete is poured to a position above the raft reinforcing steel bars 6, at the moment, the lower end parts of the upright posts 1 and the support rods 3 are buried in the concrete, and the upper end parts of the upright posts 1 are exposed outside the concrete. After the initial setting of the concrete, the entire scaffold is removed before the final setting (about 3 hours). The reserved concrete holes can be refilled with high-grade cement mortar or cement mortar with a concrete ratio.

In the embodiment, the upright post 1 can be easily taken out of concrete by using the simple structure of the upright post 1, and the threaded connection between the upright post 1 and the sleeve 2 can realize effective separation of the upright post and the sleeve and can be taken out by decomposition. Bracing piece 3 also is convenient for take out from the concrete with the detachable setting of sleeve pipe 2, and this repeatedly usable's steel bar support has effectively solved traditional support and has received the difficult problem of taking out of structure restriction in the concrete, has realized the used repeatedly of support, has practiced thrift the material.

The installation and construction method of the steel bar support comprises the following specific steps:

1) after the binding of the steel bars is finished, vertically inserting the upright post 1 into the steel bars;

2) sleeving the sleeve 2 into the upright post 1, and screwing the support rod 3 into a threaded hole in the sleeve 2;

3) two fixing nuts 4 are screwed in the outer side of the support rod 3, and the raft plate steel bar 6 to be supported is fixed between the two fixing nuts 4;

4) adjusting the height of the sleeve 2 to the position required to be controlled by the raft steel bar 6, and screwing the support rod 3 to fasten the sleeve 2.

5) After the concrete is poured, the supporting rods 3 are loosened before the concrete is initially set (about 3 hours) and all the materials are taken out. And (3) recharging high-grade cement mortar (or cement mortar with concrete proportion).

Whole process step flow is few, easy operation, and steel bar support plays effective support to raft reinforcing bar 6, and can carry out the nimble control of raft reinforcing bar 6 height through the position that control sleeve 2 is fixed, has solved the problem that traditional support height is not adjustable. All parts of the steel bar support can be taken out of concrete, and can be repeatedly used in the supporting process of the raft plate steel bars 6, so that a large amount of materials are saved, and the construction cost is reduced.

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.
