DETAILED DESCRIPTION

[0027] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0028] Reference Figures 1 to 5 , this embodiment provides a steel bar cage frame, which includes a base 1, a lower mold 2 connected to the base, and an upper mold 3 connected to the lower mold;

[0029] The base comprises a bottom plate 11 and a support plate 12 vertically connected to the middle of the bottom plate, a semicircular give way groove 13 with an opening facing upward is formed in the middle of the support plate, and a plurality of circumferentially arranged adjusting members 16 that can change their positions in the radial direction of the give way groove are connected along the edge of the give way groove 13. Specifically, the support plate is provided with a plurality of circumferentially arranged strip positioning holes 15 at the edge of the give way groove, and the length direction of the strip positioning holes is consistent with the radial direction of the give way groove. A mounting hole 161 is provided at one end of the adjusting member, and the adjusting member and the support plate can be relatively fixed by screws passing through the mounting hole and the strip positioning hole. The fixed position of the adjusting member can be changed by changing the matching position of the mounting hole and the strip positioning hole. A fixing portion for connecting the lower mold is formed at the other end of the adjusting member, and the fixing portion is provided with a first connecting hole 166;

[0030] The lower mold comprises a semicircular first base, the first base is provided with a second connection hole 23 corresponding to the first connection hole 166, the adjustment member and the first base can be fixedly connected by screws, the inner circumference of the first base is provided with a plurality of equidistantly arranged inner positioning grooves 21 for placing the main ribs, and the two ends of the first base are provided with lower connection parts 22;

[0031] The upper mold comprises a semicircular second base, the outer circumference of the second base is provided with a plurality of equally spaced outer positioning grooves 31 for placing the main ribs, and upper connecting parts 23 are provided at both ends of the second base. The lower connecting part 22 and the upper connecting part 23 can be fixedly connected by screws, so that the lower mold and the upper mold are combined to form a structure approximately in a circular ring, at which time the inner positioning groove 21 and the outer positioning groove 31 are in a cocircular state, so that the main ribs placed in the inner positioning groove and the outer positioning groove are arranged in a circular manner; the upper mold is composed of two symmetrically arranged mold blocks 33, the ends of which can be butted against each other and connected by a connecting plate 34 to form a semicircular ring structure;

[0032] The working principle of this embodiment is as follows: prepare a plurality of bases 1, pre-adjust the adjustment member 16 on each base to the target position, and then arrange the plurality of bases in a straight line so that the center normals of the make way grooves of different bases coincide, then fix the lower jig 2 with the adjustment member 16, place the main reinforcement 4 in the inner positioning groove 21 of the lower jig in sequence, set the reinforcing ribs at the specified positions of the main reinforcements as required and weld the reinforcing ribs to the main reinforcements, then fix the upper jig 3 with the lower jig, place the main reinforcements in the outer positioning grooves 31 of the upper jig in sequence, weld the main reinforcements to the reinforcing ribs, and complete the welding step of the steel cage, then release the connection between the upper jig and the lower jig and the connection between the two jig blocks 33, so that the upper jig can be separated from the steel cage, and the steel cage can be removed from the jig frame for standby use.

[0033] It should be noted that in the present application, the "semi-circular ring" is not precisely defined as a structure with a central angle of 180° formed by dividing the circular ring in half along the diameter. In the present application, the upper mold and the lower mold are connected through the lower connecting part and the upper connecting part to form a structure that is approximately a circular ring. Therefore, the upper mold and the lower mold are approximately regarded as two semi-circular ring structures, but the lower mold and the upper mold are of different sizes and an additional connecting structure is required. At the same time, considering the processing accuracy factor, the two are not perfect semi-circular ring shapes, and their central angles will have certain deviations compared to the precise semi-circular ring.

[0034] In a further embodiment, the adjusting member 16 is provided with a limiting protrusion 161 which can be embedded in the strip positioning hole and slidably cooperate with the inner walls on both sides of the strip positioning hole. The length of the limiting protrusion is smaller than the strip positioning hole. The limiting protrusion can facilitate the installation of the adjusting member, make the direction of the adjusting member consistent with the radial direction of the give way groove, and at the same time improve the installation strength of the adjusting member.

[0035] In a further embodiment, the fixing portion includes a first limiting plate 163 and a second limiting plate 164 arranged in parallel, and a slot 165 that can accommodate the outer edge of the lower tire is formed between the first limiting plate and the second limiting plate. The second limiting plate is further extended relative to the first limiting plate to form an extension portion, and the first connecting hole 166 is provided on the extension portion. The slot and the limiting plate can facilitate the positioning and installation of the lower tire.

[0036] In a further embodiment, the base further includes a reinforcing plate 14, which is arranged perpendicular to the bottom plate and the support plate to prevent structural deformation between the support plate and the bottom plate.

[0037] Figure 6 Another connection method between the adjusting member and the mounting plate in the utility model is shown, wherein the support plate is provided with a plurality of guide members 121 at the edge of the give way groove, and the guide members are connected with a locking mechanism 122, and the guide members 121 can be slidably matched with the adjusting member 16, and the adjusting member and the guide members are relatively fixed by the locking mechanism 122, thereby changing the position of the adjusting member. In order to improve the position accuracy of the adjusting member, a scale can be set on the adjusting member.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
