[0023] Hereinafter, embodiments of the hardened ground elevation adjustable grid assembled tire rack of the present utility model will be described with reference to the drawings.

[0024] The embodiments described herein are specific specific implementation manners of the present utility model for explaining the concept of the present utility model, and are all explanatory and exemplary, and should not be construed as limiting the implementation manners of the present utility model and the scope of the present utility model. Except for the embodiments described herein, those skilled in the art can also adopt other obvious technical solutions based on the content disclosed in the claims and the specification of the present application, and these technical solutions include technical solutions that make any obvious substitutions and modifications to the embodiments described herein.

[0025] The drawings in this specification are schematic diagrams for assisting in explaining the concept of the present utility model, and schematically show the shapes of various parts and their mutual relationships. Please note that in order to clearly show the structures of the components of the embodiments of the present utility model, the drawings are not drawn according to the same scale. The same reference numerals are used to represent the same parts.

[0026] Combined with Figures 1 to 6Describes an adjustable grid assembly jig 100 for the elevation of a hardened ground in an embodiment of the present utility model, which includes:

[0027] Adjustable jig supports 1 and stable connecting beams. The adjustable jig supports 1 form a layout structure according to the support points required for grid support. The stable connecting beams are connected between two adjacent adjustable jig supports 1; for example, Figure 6 shows a steel structure grid 200. There are a total of eight grid lower chord balls 201 in it. Each group of four is arranged in a row, and two adjacent rows are arranged parallel to each other. That is to say, the adjustable jig supports 1 form a rectangular layout structure according to the support points required for grid support. Correspondingly, the adjustable jig supports are arranged at positions corresponding one by one to the grid lower chord balls. As Figure 1 shown, two rows of adjustable jig supports 1 are arranged at intervals along the long side of the rectangle. Each row of adjustable jig supports 1 is connected by a transverse stable connecting beam 2, and the corresponding adjustable jig supports 1 between adjacent rows are connected by a longitudinal stable connecting beam 3. According to the above structure, each grid lower chord ball has an adjustable jig support corresponding to it to support it, so as to bear the pressure from the grid lower chord ball and avoid the problem of unstable support caused by the number of adjustable jig supports being less than the grid lower chord balls. Of course, if the steel structure grid is of other structures and the grid lower chord balls are arranged in other ways, the number and layout of the adjustable jig supports need to be adjusted correspondingly.

[0028] The adjustable jig support 1 includes a jig base 11, a fixed column 12 and an adjustment section 13;

[0029] As Figure 3 shown, the jig base 11 includes a base transverse frame 111, a base longitudinal frame 112, a base middle longitudinal rod 113 and a base middle transverse rod 114. The base transverse frame 111 and the base longitudinal frame 112 are spliced into an outer frame of a rectangular structure. The base middle longitudinal rod 113 and the base middle transverse rod 114 are arranged in a cross shape inside the outer frame. The above jig base is preferably made of stainless steel material. In a preferred embodiment, the jig base is welded by I-beams.

[0030] The fixed column 12 is fixed on the jig base 11. The fixed column 12 includes a column body 121 and a limit block 122. The limit block 122 is fixed on the outer wall of the column body 121; preferably, the limit block is fixed at the middle position in the vertical direction of the column body.

[0031] The adjusting section 13 is provided with an adjusting groove 134. The adjusting section 13 is sleeved outside the column body 121. The adjusting groove 134 is a groove-like structure that gradually rises from bottom to top around the outer wall of the adjusting section 13. The outer wall of the adjusting section corresponding to the upper side of the adjusting groove 134 is constructed as a stepped wall 136. The limiting block 122 is rectangular or right-angled triangular. The right angle of the limiting block 122 is clamped into the stepped wall 136 for height positioning. For example, when it is necessary to adjust the height of the adjusting section to a higher position, the adjusting section is moved upward to disengage the stepped wall of the adjusting groove from the limiting block, and when it is moved to the required height, the limiting block is engaged with the corresponding stepped wall, that is, the height of the adjusting section 13 is positioned through the cooperation between the limiting block 122 and the adjusting groove 134. In Figure 5 In a specific embodiment shown, the outer wall of the adjusting section corresponding to the lower side of the adjusting groove 134 is constructed as a smooth wall 135. This structural design can prevent the limiting block from contacting and jamming with the outer wall of the adjusting section at the lower side of the adjusting groove when the adjusting section is moved upward, affecting the height adjustment operation.

[0032] The hardened ground elevation adjustable assembled jig 100 proposed by the present utility model can effectively cope with the elevations of different grid lower chord balls by adjusting the height of the support, thereby improving the construction efficiency and flexibility. This innovation not only reduces material waste but also simplifies the assembly process, ensuring the stability and safety of the structure.

[0033] In a further preferred embodiment of the hardened ground elevation adjustable grid assembled jig, the adjusting section 13 includes an adjusting column 131, a balance plate 132, and a grid ball limiting member 133. The balance plate 132 is fixed to the top of the adjusting column 131, and the grid ball limiting member 133 is fixed to the top of the balance plate 132. In a specific embodiment, the grid ball limiting member 133 is a round tube, and the diameter of the round tube is adapted to the size of the grid lower chord ball 201. The bottom of the grid lower chord ball 201 can be placed into the round tube. For example, the diameter of the grid lower chord ball is 10 cm and the diameter of the round tube is 8 cm. Such a fit enables the lower part of the grid lower chord ball to be placed into the round tube, preventing the grid lower chord ball from moving. In another preferred embodiment, the grid ball limiting member is a spherical bowl structure, and the grid lower chord ball can be placed into the spherical bowl structure.

[0034] In such as Figure 7 and Figure 8In a preferred embodiment shown, the fixed column 12 includes a column body 121 and a limit block 122, and the limit block 122 is fixed to the outer wall of the column body 121; the fixed column 12 further includes a screw 123, a nut 124 and a pressure plate 125. The screw is vertically fixed on the surface of the limit block, the nut is installed on the screw, and the pressure plate is sleeved on the screw and is located between the nut and the limit block. When it is necessary to adjust the height of the adjustment section to a higher position, move the adjustment section upward to disengage the stepped wall of the adjustment groove from the limit block, and when it is moved to the required height, engage the limit block with the corresponding stepped wall, and then adjust the position of the nut on the screw to move the nut in the direction towards the limit block. Since the limit block is arranged in the adjustment groove, the limit block is flush with or not higher than the outer surface of the adjustment section in height; therefore, by tightening the nut to lock the pressure plate, the pressure plate can be made to closely adhere to the outer surface of the adjustment section, thereby realizing the position locking of the fixed column and the adjustment section.

[0035] The disclosed technical features are not limited to the combinations with other disclosed features. Those skilled in the art can also make other combinations among the technical features according to the purpose of the utility model, taking the achievement of the purpose of the utility model as the criterion.
