The term "connected" can be direct or indirect, that is through intermediary components (elements). The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments".

[0025] It should be noted that the terms "first", "second", and the like in the present application are only used to distinguish different devices, modules or units, and are not intended to limit the devices, modules or units to be different devices, modules or units, nor to limit the order or interdependence of the functions performed by the devices, modules or units.

[0026] In view of the problem of fixed size of the steel bar cage binding jig frame, the present application provides a steel bar installation positioning jig frame, which comprises a jig frame base 1, a positioning support frame 2 and a positioning steel plate 3. The positioning support frame 2 is fixed on the jig frame base 1, and the positioning steel plate 3 is installed on the jig frame base 1 through the positioning support frame 2. The positioning steel plate 3 is used to assist in binding the steel bars of the steel bar cage of the concrete member under construction, so that different positioning steel plates 3 can be replaced to adapt to the processing of steel bar cages of different diameters. That is, when processing steel bar cages of different diameters, the jig frame does not need to be replaced as a whole, but only the positioning steel plate 3 of different specifications needs to be replaced based on the original jig frame, which greatly improves the work efficiency and reduces the device cost of the steel bar installation positioning jig frame.

[0027] Specifically, the top side of the positioning steel plate 3 is recessed downward to form a groove 31, the diameter of the groove 31 is consistent with the diameter of the steel bar cage required to be bound, and a plurality of steel bar positioning grooves 32 are arranged at intervals on the groove 31. The positioning of the steel bars is realized through the steel bar positioning grooves 32. The worker only needs to place the steel bars to be bound according to the steel bar positioning grooves 32, which is simple to operate.

[0028] In different embodiments, the grooves 31 can be provided with different groove 31 shapes according to the shape of the reinforcement cage of the concrete member being constructed, for example, when a cylindrical reinforcement cage with a circular cross-section needs to be bound, the groove 31 is an arc-shaped groove 31, and when a square reinforcement cage with a rectangular cross-section needs to be bound, the groove 31 is a square groove 31, and a special-shaped groove 31 is also provided to meet the binding needs of the special-shaped structure of the reinforcement cage.

[0029] The positioning support frames 2 are provided in two groups on both sides of the jig base 1, and the two groups of positioning support frames 2 limit the two sides of the positioning steel plate 3, respectively, to ensure the stability of the support of the positioning steel plate 3. Furthermore, each group of positioning support frames 2 is provided with at least two along the axial direction of the concrete member being constructed, so that the positioning steel plate 3 is clamped between the adjacent two positioning support frames 2 of each group, and the positioning steel plate 3 is installed in a plug-in manner between the adjacent two positioning support frames 2 of each group, which is convenient to disassemble and can facilitate workers to replace different positioning steel plates 3 according to the size of the reinforcement cage to be bound.

[0030] Furthermore, to improve the binding effect of the long reinforcement, the positioning steel plate 3 is provided with N pieces along the axial direction of the concrete member being constructed, and N≥2, so that the reinforcement is positioned by at least two positioning steel plates 3, which can improve the accuracy of the binding of the reinforcement cage. Since the positioning steel plate 3 needs to be plugged between the adjacent two positioning support frames 2, the number of each group of positioning support frames 2 in the embodiment is N+1.

[0031] The positioning steel plate 3 of the present application is supported and limited by the positioning support frames 2 installed on the jig base 1, and each positioning support frame 2 in the present application includes a stand 21 and an inclined rod 22. The stand 21 extends along the axial direction of the concrete member being constructed, and the inclined rod 22 is obliquely arranged between the stand 21 and the jig base 1, and the inclined rod 22 is lower than the groove 31 of the positioning steel plate 3, avoiding the influence of the inclined rod 22 on the binding of the reinforcement. The positioning support frame 2 of the present application forms a triangular structure between the inclined rod 22, the stand 21 and the jig base 1, thereby increasing the stability and carrying capacity of the positioning support frame 2, and effectively dispersing and transmitting the stress to the jig base 1 or other support points, preventing the positioning support frame 2 from tilting, twisting or collapsing, to improve the positioning and supporting effect of the positioning steel plate 3.

[0032] Furthermore, the height of the stand 21 is not less than the height of the positioning steel plate 3, ensuring that the top of the positioning steel plate 3 also has good supporting capacity.

[0033] The stand 21 of the embodiment comprises two lengthwise working steels 211 arranged in an up-down manner and vertical working steels 212 arranged between the two lengthwise working steels 211, the lengthwise working steels 211 extend along the axial direction of the concrete member to be constructed, the height of the stand 21 can be adjusted by selecting vertical working steels 212 with different lengths, meanwhile, the vertical working steels 212 are arranged in multiple along the length direction of the lengthwise working steels 211 to ensure the structural stability of the stand 21, the lengthwise steel bars at the bottom of the stand 21 can be fixed on the jig base 1 by welding or screwing.

[0034] In addition, one end of the inclined rod 22 is connected with the lengthwise working steel 211 at the top of the stand 21, and the other end is fixed with the jig base 1, thereby forming a triangular stable structure, and multiple inclined rods 22 are arranged along the length of the lengthwise working steel 211, thereby greatly increasing the structural stability of the positioning support frame 2.

[0035] In summary, the steel bar installation positioning jig of the present application can replace the positioning steel plate 3 with different groove 31 structures to adapt to the processing of steel bar cages with different diameters by inserting the positioning steel plate 3 between each group of two adjacent positioning support frames 2 arranged on the jig base 1, thereby greatly improving the work efficiency, reducing the cost of the steel bar installation positioning jig, and having high applicability.

[0036] The above only describes some embodiments of the present application, and it should be noted that those skilled in the art can make some improvements and refinements without departing from the principles of the present application, and these improvements and refinements should also be considered as the protection scope of the present application.
