Detailed Description

Other advantages and effects of the present utility model will become apparent to those skilled in the art from the following disclosure, which describes the embodiments of the present utility model with reference to specific examples. The utility model may be practiced or carried out in other embodiments that depart from the specific details, and the details of the present description may be modified or varied from the spirit and scope of the present utility model.

The utility model is described in further detail below with reference to fig. 1-3.

The embodiment of the utility model discloses a retaining wall steel template reinforcing structure and a construction method thereof. Referring to fig. 1-3, the retaining wall steel form reinforcing structure comprises a plurality of steel forms 1 spliced together and a plurality of groups of fixing components 2 for fixing the steel forms 1, wherein the fixing components 2 comprise a pair of pull screws 21 for fixing the steel forms 1 on two sides of a retaining wall to be poured and a plurality of reinforcing rods 22 transversely arranged on the steel forms 1, in the embodiment, every two reinforcing rods 22 are in a group, two groups are arranged from right to bottom to top according to the steel forms 1, and the number of the groups of the reinforcing rods 22 can be determined according to the specification and the size of the steel forms 1; the opposite-pulling screw rod 21 passes through two adjacent reinforcing rods 22, locking pieces 23 for fixing the reinforcing rods 22 are arranged at two ends of the opposite-pulling screw rod 21, the locking pieces 23 in the embodiment are butterfly buckles and nuts, the butterfly buckles pass through the opposite-pulling screw rod 21 to abut against the reinforcing rods 22, and the butterfly buckles are fixed on the opposite-pulling screw rod 21 through nut pieces, so that the reinforcing rods 22 are fixed on the steel template 1.

In order to facilitate the splicing of a plurality of steel templates 1 together, rib walls 11 are folded at the peripheral sides of the steel templates 1, and the rib walls 11 of two adjacent steel templates 1 are attached to each other and fixedly connected through bolts; simultaneously in order to avoid when installing reinforcing rod 22, the condition that crooked inconvenient fixed appears in reinforcing rod 22, steel form 1 is located on rib wall 11 from bottom to top and is equipped with a plurality of constant head tanks 12 that are used for preventing reinforcing rod 22 gliding, constant head tank 12 is convex, reinforcing rod 22 can just put into in the constant head tank 12, when installing reinforcing rod 22, can directly keep whole reinforcing rod 22 on same horizontal line through constant head tank 12, the installation is more convenient, can avoid steel form 1 to receive the impact of concrete when pouring concrete simultaneously and lead to the gliding condition to appear in reinforcing rod 22.

Meanwhile, in order to ensure that the steel template 1 can bear larger impact force when concrete is poured, the steel template casting device further comprises a plurality of groups of supporting components 3 which are arranged on one side of the steel template 1 and used for supporting the steel template 1, each supporting component 3 comprises a supporting plate 31 which is abutted against the steel template 1 and a supporting rod 32 which is used for tightly supporting the supporting plate 31 on the steel template 1, the supporting rods 32 are fixed on the ground, the end parts of the supporting rods 32 are hinged with the supporting plates 31, when concrete is poured, the situation that gap grouting occurs due to deformation of the lower side of the steel template 1 is easy to cause because the impact force received by the lower part of the steel template 1 is the largest, the supporting plates 31 are abutted against the position of the steel template 1 close to the bottom, in this embodiment, the supporting plates 31 are abutted against the lower part of the lowest reinforcing rods 22, and the supporting plates 31 and the supporting rods 32 can play a good supporting role on the steel template 1 when concrete is poured, so that the possibility of deformation and slurry leakage of the lower side of the steel template 1 is reduced.

Meanwhile, when the steel template 1 is impacted by concrete, the bottom side of the steel template 1 tends to move to two sides, so that the supporting plate 31 is easy to slide upwards on the steel template 1, the supporting plate 31 loses the supporting effect, the rib walls 11 on the two sides of the steel template 1 are provided with limiting blocks 13, the top of the supporting plate 31 is abutted against the limiting blocks 13, the limiting blocks 13 can enable the supporting plate 31 to be at a fixed position on the steel template 1, the supporting plate 31 can be prevented from moving on the steel template 1, and the possibility of deformation of the bottom side of the steel template 1 can be reduced; meanwhile, the two ends of the supporting plate 31 are abutted against the rib walls 11 on the two sides of the steel template 1, so that the contact area between the supporting plate 31 and the steel template 1 is larger, and the supporting effect can be further improved.

Because the thickness of the supporting plate 31 is smaller, when a larger force is applied, the supporting plate 31 is likely to deform, the top plate 33 of the supporting plate 31 is folded and provided with the top plate 33 for abutting against the limiting block 13, the supporting plate 31 is contacted with the limiting block 13 through the top plate 33, the contact area between the supporting plate 31 and the limiting block 13 is increased, and the supporting plate 31 is abutted against the limiting block 13 more firmly; simultaneously, the limiting groove 14 is formed in the bottom side of the limiting block 13, the top plate 33 is abutted against the limiting groove 14, the top plate 33 is limited through the limiting groove 14, sliding of the top plate 33 on the limiting block 13 can be avoided, and the supporting plate 31 is abutted against the steel template 1 more firmly.
