Embodiment Construction

[0032] The present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.

[0033] The column expansion joint airbag template as shown in the figure includes 2 reinforcement plates 1, an inflatable air bag 3 and a plurality of limit rods 2 for limiting the width of the predetermined expansion joint 24; On both sides, the inflatable airbag 3 uses its internal pressure to reinforce the two reinforcing plates 1; multiple limit rods 2 are arranged in parallel and perpendicular to the reinforcing plate 1;

[0034] The inflatable airbag 3 is provided with an inflatable port 9 for inflating, a pressure gauge 12 for observing its internal predetermined pressure, and an air release valve 10; the air release valve 10 is used to exhaust the internal air of the inflatable airbag 3;

[0035] The limit rod 2 is composed of the front end 4 of the limit rod and the rear end 5 of the limit rod. The front end 4 of the limit rod is rod...

Abstract

The invention discloses a column expansion joint airbag template and a reinforcement method thereof. The column expansion joint airbag formwork of the present invention includes two aluminum alloy plates or steel plates, an inflatable air bag and a plurality of limit rods for limiting the width of the predetermined expansion joint; two aluminum alloy plates or steel plates are located on both sides of the inflatable air bag; The two limit rods are arranged in parallel and perpendicular to the reinforcement plate 1; there are multiple reserved holes around the reinforcement plate to facilitate the penetration of the limit rods into threaded fixing; one side of the aluminum alloy plate or steel plate is also provided with multiple reinforcements. Belt; one end of the reinforcement belt is connected with an aluminum alloy plate or steel plate, the other end of the reinforcement belt is provided with a lock, and the middle end of the reinforcement belt is provided with a rubber corner sticker to closely fit the corner of the poured concrete column. The method of the present invention cannot use traditional steel pipes and wooden beams for reinforcement at narrow expansion joints, and adopts airbag templates for column expansion joints, which can ensure construction quality, safety and construction progress.

Description

technical field [0001] The invention relates to the construction technical field of column formwork reinforcement at expansion joints of frame structures, in particular to an airbag formwork for column expansion joints and a reinforcement method thereof. Background technique [0002] Due to the influence of temperature, the concrete frame structure will expand with heat and contract with cold. In order to avoid cracks or even damage to the structure due to changes in external temperature, expansion joints are usually set at appropriate positions during the construction process. Due to the narrow width of the column expansion joints, people cannot enter. After the concrete is poured on site, due to the lateral pressure of the concrete, the formwork here cannot be completely removed, which affects both the construction quality and the progress. Contents of the invention [0003] Aiming at the deficiencies of the prior art and combined with the site practice, the object of th...
