[0025] like Figures 1 to 3 As shown, the utility model provides a pier cap placement device, comprising:

[0026] The bottom frame 100 has a plurality of pairs of lower limit holes 11 circumferentially disposed on the top thereof; the lower limit holes 11 can be configured to be cylindrical, rectangular, or have a cross-shaped transverse cross section, etc. The lower limit holes 11 are used to position and connect the fixed vertical ladder 500 .

[0027] The top frame 200 is provided with a plurality of pairs of upper limit holes 21 vertically corresponding to the plurality of pairs of lower limit holes 11 on the top, and a plurality of columns 300 are arranged between the top frame 200 and the bottom frame 100, and a vertical scale is provided on the column 300 in the vertical direction; the shape of the upper limit hole 21 can be set to be the same as the shape of the lower limit hole 11, or it can be different, but it needs to be adapted to the shape of the positioning protrusion 53. The column 300 is used to connect the bottom frame 100 and the top frame 200 to form a space for tying steel bars. The column 300 can be made of I-beams, channel steels, or round steels. The vertical scale preferably starts from the upper surface of the bottom plate 400 as the starting point 0, and the vertical scale can be set on the surface of the column 300 by spraying paint to facilitate identification of the scale. The vertical scale is used to help determine the vertical height when tying the pier cap steel bars to improve the accuracy of the pier cap steel bar tying.

[0028] The bottom plate 400 is arranged on the base frame 100. The bottom plate 400 is provided with transverse scales and longitudinal scales. The transverse scales, longitudinal scales and vertical scales form a three-dimensional coordinate system. The transverse scales and longitudinal scales can form a horizontal coordinate system, which is used to help determine the longitudinal and transverse positions when tying the pier cap reinforcement bars, and is also used to improve the accuracy of the tying of the pier cap reinforcement bars. The transverse scales and longitudinal scales can also be set by spraying paint. For easy identification, the vertical scales, transverse scales and longitudinal scales can also be sprayed with paints of different colors. The bottom plate 400 can be a one-piece steel plate, or it can be formed by fixing multiple steel plates by tie bolts.

[0029] At least one vertical ladder 500, the vertical ladder 500 includes a ladder body 51, positioning strips 52 relatively arranged on the upper and lower sides of the ladder body 51, and a pair of positioning protrusions 53 arranged at intervals at the bottom of the positioning strips 52, and the upper and lower pairs of positioning protrusions 53 are respectively movably inserted into a pair of upper limit holes 21 and a pair of lower limit holes 11. The pier cap has a certain height. When tying the steel bars from bottom to top to a certain height, it is necessary to use a lifting structure to help the construction workers. In the prior art, the construction workers usually step on the bottom steel bars that have just been tied to tie the upper steel bars, which will affect the overall accuracy of the pier cap to a certain extent. Therefore, the vertical ladder 500 is set to reduce the number of times the construction workers step on the unformed pier cap. After the positioning protrusions 53 are respectively inserted into the upper limit hole 21 and the lower limit hole 11, the vertical ladder 500 is released, and then under the action of their own gravity, the upper and lower positioning strips 52 are automatically abutted against the top frame 200 and the bottom frame 100, respectively, so that the vertical ladder 500 is stable and reliable, and can be climbed by construction workers. By installing the vertical ladder 500 on the upper limit hole 21 and the lower limit hole 11 at different positions, the position of the vertical ladder 500 can be adjusted so as to tie the steel bars at different positions.

[0030] In the above technical solution, by setting the bottom plate 400, the pier cap in the process of binding and the completed binding can be stably supported; by setting the horizontal scale, the longitudinal scale and the vertical scale to construct a three-dimensional coordinate system, the accuracy of the pier cap steel bar binding can be improved; by setting the vertical ladder 500 with the positioning strips 52 and the positioning protrusions 53, the position of the vertical ladder 500 can be adjusted to facilitate the construction workers to bind steel bars at different positions.

[0031] In another technical solution, a plurality of legs 12 are evenly arranged at the bottom of the base frame 100, and a universal wheel 13 with a brake structure is provided at the bottom of the legs 12. In the prior art, after the pier cap is tied, it is hoisted to the pier by a hoist. However, due to the tight location of the construction site, the pier cap will be tied in the factory building. Due to the small size of the factory building, the commonly used hoists cannot enter the factory building. The prior art is to use a temporary support mobile cart at the bottom of the pier cap, and multiple people cooperate to move it slowly. After moving it out of the factory building, it is hoisted to the loading vehicle and transported to the construction site by a hoist. In view of the above working conditions, this technical solution is provided with legs 12 and a universal wheel 13 with a brake structure. When the pier cap is tied, the brake is released, and the device can be pushed to move outside the factory building, which significantly improves the movement efficiency and stability of the pier cap.

[0032] In another technical solution, a plurality of transverse bracing plates 14 are arranged at intervals along the horizontal direction on the bottom frame 100, and a plurality of longitudinal bracing plates 15 are arranged along the longitudinal direction on the bottom frame 100. The plurality of longitudinal bracing plates 15 and the plurality of transverse bracing plates 14 form a support grid, and the bottom plate 400 is arranged on the support grid. The top frame 200 and the bottom frame 100 are formed by welding I-beams, and the longitudinal bracing plates 15 and the transverse bracing plates 14 are welded to form the support grid, and the support grid is welded to the bottom frame 100. The support grid is provided to improve the support stability of the bottom plate 400.

[0033] In another technical solution, a plurality of positioning circular plates 31 are arranged at intervals on the column 300, and the positioning circular plates 31 are arranged horizontally, and the distance between the positioning circular plates 31 and the zero point of the vertical scale is an integer centimeter. By setting the positioning circular plates 31, the scale recognition speed can be improved, and the support force can be provided when the steel bars are initially tied.

[0034] In another technical solution, the top frame 200 is provided with a plurality of lifting ears 22, and the plurality of lifting ears 22 are arranged in a rhombus shape, and the geometric center is on the same vertical line as the geometric center of the top frame 200 and the bottom frame 100. Since the pier cap is often in a shape of being larger at the top and smaller at the bottom, there is a hidden danger of shaking during transportation. In this technical solution, by providing a plurality of lifting ears 22, the placement device (top frame 200) and the pier cap can be hoisted onto a transport vehicle together and transported to the construction site together. After arriving at the construction site, it is also possible to lay tracks on the ground according to specific circumstances, for example, if the transport vehicle cannot reach a position very close to the pier, then the placement device and the pier cap can be hoisted to the ground together, and the universal wheel 13 can be made to fall into the track at the same time, and then after releasing the brake, the placement device is pushed to the position closest to the pier, and then the pier cap is hoisted to the pier construction position using a hoist.

[0035] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
