This patent can reach following beneficial effect:

the utility model discloses a concrete placement construction's of having combined two F shaped steel muscle fixtures and concrete protective layer cushion appurtenance, this appurtenance both can guarantee the reinforcing bar interval, makes it not take place whole skew, dislocation or warp, also can make reinforcing bar protective layer thickness obtain effective control, avoids too thin or too thick to have advantages such as reliable and stable, easy and simple to handle, low cost.

Drawings

The invention will be further explained with reference to the following figures and examples:

FIG. 1 is a diagram showing the effect of the present invention in example 1;

FIG. 2 is a schematic structural view of the present invention in example 1;

fig. 3 is a schematic diagram of the structure of the present invention in embodiment 2.

In the figure: the steel plate protective layer comprises a main supporting rod 1, a hollow rod 101, a supporting rod 102, radial insertion holes 103, supporting rods 2, a threaded rod 3, a protective layer cushion block 4, a hexagonal prism column 401, a protective layer body 402, a plug pin 5, a main steel bar 6 and a template 7.

Detailed Description

Example 1:

as shown in fig. 1 to 2, a concrete pouring construction auxiliary tool includes a main support rod 1, wherein two ends of the main support rod 1 are respectively provided with a support rod 2 vertically connected with the main support rod 1, and the two support rods 2 and the main support rod 1 form an "F" -shaped steel bar fixture; two ends of the main support rod 1 are respectively provided with a threaded rod 3, and the threaded rods 3 are in threaded connection with the protective layer cushion blocks 4. The F-shaped steel bar clamp is used for being clamped on two main steel bars 6, and the protective layer cushion block 4 is used for being in contact with the template 7.

The threaded rod 3 can adopt a pointed bolt, so that the installation is convenient. The protective layer cushion block 4 can adopt a concrete block, when the concrete block is adopted, an internal thread pipe can be embedded in the concrete block, and the distance between the two protective layer cushion blocks 4 can be changed by rotating the protective layer cushion block 4. Can adopt the spanner when rotatory protective layer cushion 4, for the convenience of spanner operation, protective layer cushion 4 can adopt following two kinds of forms:

first, the protective layer pad 4 is a square block. The square protective layer cushion block 4 is directly rotated by a spanner for adjustment. The size of the protective layer cushion block 4 is not easily made too large due to the size of the wrench.

Secondly, the protective layer cushion block 4 is provided with a square column or a hexagonal column 401, the square column or the hexagonal column 401 is provided with an internal thread hole, and the internal thread hole is in threaded connection with the threaded rod 3; the outer ends of the square pillars or hexagonal pillars 401 are connected to the protection layer body 402. The size of the protective layer body 402 can be increased by the design, and the position of the protective layer cushion block 4 can be adjusted by rotating the hexagonal prism column 401 with a wrench.
