Embodiment 1
[0015] A pre-filled construction tool for concrete expansion joints such as figure 1 , figure 2 As shown, it includes a left side panel 101, a right side panel 102, a roller 20 and a pressure roller 30, the two ends of the roller 20 are respectively fixed on the bottom of the left and right side panels, and the pressure roller 30 is fixed on the long screw rod of the pressure roller At the center position of 301, both ends of the long screw rod 301 of the pressure roller are fixed on the bottom of the front end of the left and right side panels; the pressure roller 30 is as wide as the expansion joint, and extends downward by 25mm beyond the roller.
[0016] During travel, the roller 20 rolls against the ground to reduce friction and save energy. The pressure roller 30 is embedded in the expansion joint to ensure that the expansion joint is maintained at a set value between 20-30mm, and there will be no inconsistent depth of the expansion joint The problem.

The invention discloses a pre-filling construction tool for a concrete expansion joint, and relates to the technical field of concrete expansion joint construction. The pre-filling construction tool comprises left and right panels, a drum and a pinch roller, wherein two ends of the drum are respectively fixed at the bottoms of the left and right panels, the pinch roller is fixed in the center of a pinch roller long screw, and two ends of the pinch roller long screw are fixed at the bottoms of the front ends of the left and right panels; the pinch roller is as wide as the expansion joint, and exceeds the drum 20-30 mm downward. The pre-filling construction tool can be used for realizing pretreatment of the expansion joint by a simple structural combination, perfectly solving the problem that the construction result is influenced by inconsistent depth of the expansion joint, and greatly improving the construction effect of the expansion joint.
Description
technical field [0001] The invention relates to the technical field of concrete expansion joint construction, in particular to a pre-filled construction tool for concrete expansion joints. Background technique [0002] Expansion joint refers to a structural joint set at an appropriate position along the direction of the construction joint of a building or structure in order to prevent the building components from thermal expansion and contraction caused by climate temperature changes, causing cracks in the structure. Generally, polyurethane is used to fill expansion joints, but the construction quality of existing expansion joint filling generally has problems such as insufficient depth of polyurethane joint filling materials, unevenness, and unsightly appearance. Contents of the invention [0003] In view of the above problems, the present invention provides a pre-filled construction tool for concrete expansion joints. [0004] A construction tool for pre-filling concret...
