Test device for measuring lateral pressure of concrete template

Abstract

The invention provides a test device for measuring lateral pressure of a concrete template. The test device comprises a base plate, at least one pair of opposite pouring templates, at least one pair of opposite pressure measurement templates, at least one steel bar meter, at least one split bolt, a plurality of surrounding purlins and a plurality of vertical ribs, wherein the pouring templates and the pressure measurement templates form a pouring space together with the base plate; the pressure measurement templates are positioned between the opposite pouring templates; a plurality of vertical ribs are arranged on one side, which is far away from the pouring space, of each pouring template and one side, which is far away from the pouring space, of each pressure measurement template; each steel bar meter is used for pulling and fixing one pair of opposite pressure measurement templates through a clearance between each surrounding purlin and each vertical rib; a protection sleeve sleeves the outer side of each steel bar meter and is positioned in the pouring space. The pressure measurement temperatures are pulled by the steel bar meter, so that the lateral pressure on the pressure measurement templates can be measured; furthermore, the protection sleeves are arranged on the outer sides of the steel bar meters, so that the steel bar meters in a test can be repeatedly used for multiple times, and the aim of lowering the test cost is achieved.

Description

technical field [0001] The invention belongs to the field of building construction, in particular to a test device for measuring the lateral pressure of a concrete formwork. Background technique [0002] In recent years, in the construction of civil buildings and bridges, there have been reports of formwork collapse events. With the continuous development of construction technology and concrete materials, the construction site puts forward higher requirements for the pressure on the clear formwork. [0003] The horizontal load generated by the newly poured concrete on the formwork is different from the gravity load of the platform formwork. The effect of the newly poured concrete pushing the formwork horizontally outward is similar to that of water pushing the container wall. However, unlike water pressure, the lateral pressure of concrete on the formwork is a complex variable, which will vary to varying degrees with changes in concrete materials, pouring conditions, time, ...
