Problems solved by technology

However, the traditional shaped formwork cannot adjust the height of the pad stone, and it is difficult to control the height difference of the four corners. The support is prone to local edge voids. Over time, shear deformation or damage will occur due to uneven force, and it is inconvenient to find that there is a problem with the support. Replacement and Adjustment

[0026] An adjustable bearing pad stone formwork, including a rectangular formwork made of square steel and a formwork adjustment device, the rectangular formwork is made of two horizontal square steels and two vertical square steels connected to each other, and the adjacent horizontal A detachable connection is formed between the square steel and the vertical square steel through a connecting device.

[0027] In one embodiment of the present invention, the connecting means are bolts.

[0028] In another embodiment of the present invention, the connecting means are pins.

[0029] In another embodiment of the present invention, tie rods or stiffening members are arranged between adjacent horizontal square steels and vertical square steels to provide assistance for fixing the formwork.

[0030] An obvious difference that the present invention is superior to the prior art is that the rectangular formwork is made of square steel, while the prior art generally adopts wooden formwor...

[0033] Use epoxy resin mortar to fill the gap, and the mix ratio (weight ratio) of epoxy resin mortar is as follows:

[0034] Epoxy wax (6101): 95-99,

[0035] Ethylenediamine: 11-14,

[0036] Triethylenetetramine: 13-15,

[0037] Dibutyl phthalate: 8-11,

Abstract

The invention discloses an adjustable support pad stone template. The adjustable support pad stone template comprises a rectangular template and a template adjusting device, wherein the rectangular template is made of square steels; the rectangular template is made by connecting two transverse square steels with two vertical square steels; the transverse square steels and the vertical square steels, which are adjacent to each other, are detachably connected with each other through connecting devices; the template adjusting device comprises angle irons and angle screws which are correspondinglypaired with the square steels; the template adjusting device is movably connected with the rectangular template and used for adjusting elevation of the template and height differences of four cornersof the top surface of the template; and the angle screws are fixed at the four corners of the angle irons. According to the adjustable support pad stone template, it can be guaranteed that the elevation of support pad stone is accurate and the height differences of the four corners of the support pad stone conform to a specified value; and the quality of the support pad stone can be improved.

Description

technical field [0001] The invention relates to the field of bridge engineering, in particular to the technical field of bridge engineering bearing pad stone formwork. Background technique [0002] The bridge support pad stone is an important part of the bridge structure, and its quality directly affects the service life and structural safety of the bridge. The support pad stone is a short reinforced concrete column arranged at the position of the support on the pier cap, and the support pad stone plays an important role in ensuring the quality of the support from damage. The support pad stone has the unique characteristics of small concrete volume, large force, stress concentration, and high construction precision requirements. [0003] In bridge engineering, the slope of the bottom of the bridge beam is inconsistent with the slope of the top of the pier, the height of the support is inconsistent, or the height of the two bridges is inconsistent. In the prior art, the slop...
