[0030] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0031] like Figures 1 to 5As shown, a T-beam web stirrup mounting frame includes a frame 1, bottom positioning members 2 symmetrically fixed to the left and right sides of the top of the frame 1, and a cylinder 4; the bottom positioning members 2 are used to place the bottom of the T-beam web stirrups, and the bottom positioning members 2 are provided with a plurality of bottom slots 21 corresponding to the bottom of the T-beam web stirrups;

[0032] The telescopic end of the cylinder 4 is fixed with a side positioning member 3 via a bent plate connector 5;

[0033] The side positioning member 3 is provided with a plurality of mounting grooves 31 corresponding to the side parts of the T-beam web stirrups. The mounting grooves 31 on the side positioning members 3 on both sides are opposite to each other and are used to clamp and position the side parts of the T-beam web stirrups from both sides; the mounting grooves 31 are provided corresponding to the bottom clamping grooves 21; the mounting grooves 31 can be moved forward and backward by the extension and contraction of the cylinder 4, so that the distance between the mounting grooves 31 on both sides can be changed, thereby achieving the clamping or complete release of the T-beam web stirrups.

[0034] Figure 6 This is a schematic diagram of the structure of the T-beam web stirrups positioned in this utility model. For a T-beam web stirrup, if Figure 5 As shown, it has two bottom slots 21 for positioning at the bottom, and mounting slots 31 for positioning on the left and right sides, respectively, with a total of four fulcrums. After the T-beam web stirrups are placed and during the process of the cylinder 4 extending and retracting the clamping side positioning parts 3, the position of the T-beam web stirrups can be effectively fixed to ensure their longitudinal alignment and verticality.

[0035] like Figures 1 to 5 As shown, the cylinder 4 can be installed on the outside or inside of the side locating member 3. Considering that installing the cylinder 4 on the outside will increase the overall width of the mounting frame and may affect the installation and movement of other auxiliary structures, the present embodiment preferably installs the cylinder 4 on the inside of the side locating member 3, that is, both cylinders 4 are located between the side locating members 3 on both sides. At the same time, in order to avoid the bottom locating member 2, the cylinder 4 is set below the bottom locating member 2. If the two symmetrically arranged groups of cylinders 4 are counted as one group, the telescopic ends of each group of cylinders 4 are facing each other. This arrangement not only ensures the basic requirements of positioning and clamping the T-beam web stirrups, but also has a compact structure and does not hinder the installation or movement of other components on both sides of the frame 1.

[0036] Further, such as Figures 1 to 3 、 Figure 5As shown, the frame 1 includes top beams symmetrically arranged left and right, legs fixed to the lower side of the top beams and a first frame plate 11, as well as a second frame plate 12 fixed to the upper side of the top beams; first mounting holes corresponding to the mounting positions of two cylinders 4 are provided on the first frame plate 11, and mounting seats 41 are installed at the left and right ends of the cylinder 4, and the cylinder 4 is installed on the first frame plate 11 through the mounting seats 41. At least two bottom groove mounting holes 23 are provided at the bottom of the bottom positioning member 2, and the bottom positioning member 2 is installed on the second frame plate 12 by rivets or bolts passing through the bottom groove mounting holes 23. Adjustable feet 13 are installed at the bottom of the legs to meet the adjustment requirements of different heights of the tire rack.

[0037] Further, as Figures 1 to 3 、 Figure 5 shown, the position of the bottom positioning member 2 is between the two top beams; the lateral gap between the bottom positioning member 2 and the top beam on the same side is denoted as the active gap, the bent plate connecting member 5 is arranged in the active gap, and the width of the active gap is not less than 25 mm, and preferably the width of the active gap is 31 mm - 35 mm.

[0038] Further, as Figures 1 to 3 、 Figure 5 shown, the cross-section of the bottom positioning member 2 is L-shaped, the bottom card slot 21 is opened at the upper part of the bottom positioning member 2, and a number of reinforcing ribs 22 are vertically fixed inside the bottom positioning member 2 to enhance rigidity.

[0039] Further, as Figures 1 to 5 shown, the side positioning member 3 includes a U-shaped plate frame 33 and a grooved plate 34 fixed to the U-shaped plate frame 33, and the internal space of the grooved plate 34 forms a mounting groove 31; side mounting holes 32 for bolt-mounting the side positioning member 3 are provided at the bottom of the U-shaped plate frame 33; the overall shape of the grooved plate 34 is approximately the outer contour of the letter Y, and the cross-section is a "凵" shape or a U shape; the top of the mounting groove 31 is trapezoidal in reverse, which is convenient for inserting the stirrups of the T-beam web; the middle and lower parts of the mounting groove 31 are rectangular and adapted to the diameter of the stirrups of the T-beam web, which is convenient for keeping the stirrups of the T-beam web vertical after insertion and ensuring the perpendicularity.

[0040] Further, as Figures 1 to 5 shown, the bent plate connecting member 5 serves to mount the side positioning member 3 to the cylinder 4, the bent plate connecting member 5 is fixed to the bottom surface of the side positioning member 3, and the cross-section of the bent plate connecting member 5 is an inverted L shape, so that it can move left and right in the active gap without collision; a relief hole 51 is provided in the middle and upper part of the bent plate connecting member 5 corresponding to the position of the mounting groove 31, and during use, part of the stirrups of the T-beam web are placed in the relief hole 51; a triangular plate 52 for enhancing rigidity is also fixed to the bent side of the bent plate connecting member 5.

[0041] In this embodiment, Figures 1 to 3 、 Figure 5 As shown, the length of the frame 1 is no less than the T-beam web reinforcement skeleton, resulting in its long length. Accordingly, there are three sets of legs, each consisting of two symmetrically arranged legs. Each side has three side locators 3, three bottom locators 2, and three cylinders 4. The cylinders 4 are connected to the center of the side locators 3 via bent plate connectors 5. Three sets of second frame plates 12 are provided, each with two bottom locators 2. Each bottom locator 2 is fixedly mounted on the second frame plate 12 of the same set; the first frame plate 11 is positioned between the two second frame plates 12 of the same set.

[0042] The present invention provides a bottom clamping groove 21 at the bottom and mounting grooves 31 on both sides for clamping the T-beam web stirrups. The bottom clamping groove 21 and mounting groove 31 are arranged in a corresponding manner. The two work together to fix the stirrups and ensure the verticality of the stirrups. The mounting groove 31 and the bottom clamping groove 21 are arranged in three spacings: 50mm, 100mm, and 150mm to accommodate different T-beam web stirrup installation spacings.

[0043] The workflow of this utility model is:

[0044] (1) Before installing the T-beam web stirrups, the installation slot 31 is driven by the cylinder 4 to retreat 18 mm to ensure that there is enough space on the side to facilitate the easy insertion of the T-beam web stirrups during installation, thereby increasing the allowable range for the insertion of the T-beam web stirrups and facilitating the installation of the T-beam web stirrups.

[0045] (2) After all the stirrups are installed on the frame according to the designed spacing, the installation groove 31 is driven by the cylinder 4 to move forward a certain distance, such as extending 18 mm, so that the distance between the installation grooves 31 on both sides is reduced, and the side surfaces of the T-beam web stirrups are aligned, and the stirrups are clamped at the same time.

[0046] (3) After the web stirrups of the T-beam are aligned and clamped, the longitudinal reinforcement of the web is installed, and the web stirrups of the T-beam are welded firmly to the longitudinal reinforcement to form a reinforcement cage (T-beam web reinforcement skeleton).

[0047] (4) Use a gantry crane in conjunction with a sling to fix the steel cage. The installation slot 31 is driven by the cylinder 4 to move back 30 mm, and the T-beam web stirrups are released from the clamped state. The T-beam web stirrups are completely withdrawn from the installation slot 31. At this time, the steel cage is only placed on the bottom positioning piece 2; use the sling to lift the steel cage out of the stirrup installation frame and transfer it to the next site.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
