Description

Technical Field

[0001] The utility model relates to the technical field of templates for pier column casting, in particular to a template for pier column construction. Background Art

[0002] The formwork for pier casting usually uses steel formwork for formwork support and concrete pouring to form the bridge pier structure. These formworks are designed to match the shape of the pier and have sufficient strength and stability to withstand the weight and pressure when pouring concrete.

[0003] After the steel cage is installed on the pier cap, the formwork for casting the pier needs to be installed on the cap. When installing the existing formwork, the accuracy of the overall formwork needs to be ensured. The formwork is composed of several layers of stacked sub-formworks, so the accuracy of the bottom formwork installation is particularly important. After adjusting the position and level of the bottom formwork, the gap between the bottom formwork and the cap needs to be resolved to avoid large amounts of leakage and overflow, which leads to problems such as low efficiency and low precision when installing the formwork. Utility Model Content

[0004] The utility model aims to provide a template for pier column construction, which solves the problems of low efficiency, low precision and easy leakage of slurry when installing traditional templates.

[0005] The embodiment of the utility model is realized by the following technical scheme: a template for pier column construction, comprising a plurality of sub-templates vertically stacked and arranged on a pier cap, wherein a plurality of positioning screws are vertically pre-embedded on the pier cap;

[0006] A positioning plate is sleeved on the sub-template located at the bottom layer, and a plurality of positioning holes are arranged in an array on the positioning plate;

[0007] A plurality of the positioning screws are respectively slidably penetrated through a plurality of the positioning holes, two locking nuts are arranged on the positioning screws at intervals, and the positioning plate is located between the two locking nuts;

[0008] A plurality of plumb lines are arranged on the sub-template.

[0009] Furthermore, it also includes an auxiliary mold frame, an elastic member and a driving member, wherein the auxiliary mold frame and the elastic member are both slidably sleeved on the portion of the sub-mold located at the bottom of the positioning plate;

[0010] The elastic member is located between the auxiliary mold frame and the pier cap;

[0011] A plurality of driving members are arranged in a circular array on the positioning plate, and the driving members are used to drive the auxiliary mold frame to squeeze the elastic member.

[0012] Furthermore, the elastic member is a rubber tube.

[0013] Furthermore, the driving member includes a driving screw and a fixed nut, the positioning plate is provided with a plurality of through holes, and the fixed nut is coaxially fixed with the through holes;

[0014] The driving screw is threadably matched with the fixed nut, and the lower end of the driving screw slides through the through hole and abuts against the top of the auxiliary mold frame;

[0015] The driving screw is provided with a driving part, and the driving screw is driven to rotate by the driving part.

[0016] Furthermore, the driving part is a driving ring, and the driving ring is located at the top of the driving screw.

[0017] Furthermore, the cross section of the driving portion is a regular hexagon.

[0018] Furthermore, it also includes a common steel gasket and a reinforced steel gasket mounted on the positioning screw, and the common steel gasket and the reinforced steel gasket are arranged between the two locking nuts and the positioning plate on the same positioning screw, and the reinforced steel gasket is located between the common steel gasket and the positioning plate.

[0019] The technical solution of the embodiment of the utility model has at least the following advantages and beneficial effects:

[0020] 1. Use multiple plumb lines to measure the inclination of the sub-template, and then adjust the locking nuts at the bottom of each positioning screw until the sub-template is in a vertical state. It should be noted that before adjustment, the sub-template needs to be in contact with the pier cap, and then adjust the locking nut at the low position of the sub-template to finally level the sub-template at the bottom, and then adjust the locking nut at the top of the positioning screw to fix the sub-template at the bottom horizontally with the cap to ensure the horizontality of the remaining sub-templates above, and the leveling efficiency is high.

[0021] 2. The driving screw rotates, thereby realizing the up and down movement of the driving screw, usually downward movement, forcing the auxiliary formwork to compress the elastic part, thereby sealing the gap between the sub-formwork and the pier cap. The overall leveling efficiency is high and it is not easy to leak slurry.

[0022] 3. When adjusting the level of the sub-template, it can be achieved by driving the driving screw. Then the locking nuts on the several positioning screws in the early stage do not act on the positioning plate. Instead, multiple plumb lines and several positioning screws are moved downward. After the sub-template is leveled, the locking nuts on the multiple positioning screws are clamped on the positioning plate to achieve the leveling and positioning of the sub-template. In this way, the elastic part is compressed to a greater extent, thereby achieving a better effect of sealing the gap between the sub-template and the pier cap, with high overall leveling efficiency and less leakage.

[0035] During specific implementation, a plurality of plumb lines 7 are provided on the sub-template 2; the inclination of the sub-template 2 is measured by means of the plurality of plumb lines 7, and then the locking nuts 6 located at the bottom on each positioning screw 3 are adjusted until the sub-template is in a vertical state. It should be noted that before adjustment, the sub-template 2 needs to be in contact with the pier cap 1, and then the locking nuts 6 at the lower position of the sub-template are adjusted, and finally the sub-template 2 at the bottom is leveled, and then the locking nuts 6 located at the top on the positioning screw 3 are adjusted, and then the sub-template 2 at the bottom is fixed horizontally with the cap to ensure the horizontality of the remaining sub-templates above.

[0036] Embodiment 2:

[0037] Based on the above embodiments, Figure 1-5 As shown, it also includes an auxiliary mold frame 8, an elastic member 9 and a driving member 5.

[0038] A plurality of driving members 5 are arranged in a circular array on the positioning plate 4 , and the driving members 5 are used to drive the auxiliary mold frame 8 to extrude the elastic member 9 .

[0039] When implementing it, Figure 4 As shown, the auxiliary mold frame 8 is driven downward by the driving member 5, thereby deforming the elastic member 9, where the elastic member 9 is a rubber tube, or other rubber ring, etc. After being squeezed and deformed, it can seal the gap between the sub-mold 2 at the bottom after leveling and the base 1.

[0040] More specifically, the driving member 5 includes a driving screw 51 and a fixed nut 52. The positioning plate 4 is provided with a plurality of through holes 42. The fixed nut 52 is coaxially fixed with the through holes 42.
