A vibrating screed comprising a screed member, a motor, and an exciter assembly configured to vibrate the screed member in response to receiving torque from the motor via a driveshaft. The exciter assembly includes a first eccentric mass fixed on the driveshaft and a second eccentric mass axially and rotationally moveable along the driveshaft between a first position and a second position in which the second eccentric mass is axially closer to the first eccentric mass than in the first position. The vibrating screed further comprises a mode selection member to switch the exciter assembly between a first, low vibration mode, in which the second eccentric mass is in the first position, and a second, high vibration mode, in which the second eccentric mass is in the second position.

The present invention relates to a method for detecting a void in a concrete composite member covered with a steel plate using a thermal image, and a method for managing the construction of a concrete composite member covered with a steel plate by applying same. According to the present invention, since the presence of the void is determined based on the steel plate surface temperature measured using the thermal image during the construction of the concrete composite member covered with the steel plate, the void generation may be precisely expected.

The invention comprises a product. The product comprises a first removable concrete form having a concrete forming face and a first insulating panel insert having a first primary surface and an opposite second primary surface, wherein the second primary surface of the first insulating panel insert contacts the concrete forming face of the first removable concrete form. The product also comprises an elongate anchor member having an enlarged portion and an elongate portion, the elongate portion having a first end and an opposite second end, wherein the enlarged portion is disposed adjacent the first end and contacts the second primary surface of the first insulating panel insert and wherein the elongate portion extends through the first insulating panel insert and extends outwardly from the first primary surface of the first insulating panel insert. A method of using a removable insulated concrete form system is also disclosed.

A vibratory assembly has a power source with a rotational output, an implement configured to work uncured concrete, and a vibratory head means for receiving a rotational input from the power source and converting the input from the power source into mechanical oscillation and to transfer the mechanical oscillation to the implement.

A device that compensates for abrupt variations in fluid flow rate for a pump line is described. One or more aspects pertain to a system to accomplish automated in-situ placement of a concrete wall or embankment, where a fluid concrete is pumped into place, consolidated, and screeded to a finished surface, with remotely controlled or automated equipment.

A machine for removing beams from underneath formwork at an underside of a concrete slab includes a wheeled base movable on and supported at a support structure, a raisable-and-lowerable structure disposed on the wheeled base, and a beam-removal device coupled to the raisable-and-lowerable structure. The beam-removal device includes a beam-gripping mechanism. With the raisable-and-lowerable structure raised to position the beam-removal device at a beam that supports the formwork at the underside of the concrete slab, the beam-gripping mechanism operates to grasp the beam. With the beam grasped by the beam-gripping mechanism, the machine is operated to remove the beam from the formwork.

An electric work machine allows use of batteries with different sizes with battery covers and allows easy maintenance of a damaged battery cover. A rechargeable concrete vibrator includes a motor, a motor housing accommodating the motor, a battery holder connected to the motor housing to receive a battery in a detachable manner, and a battery cover to cover an overall part of the battery held by the battery holder. The battery cover is attachable to and detachable from the battery holder.

A heat generating fabric for curing outer wall concrete is provided and more specifically, to a heat generating fabric for curing outer wall concrete and an outer wall concrete curing method using the same, wherein the heat generating fabric has the effects of: enabling concrete curing even in winter; having a uniform temperature distribution; having excellent flexibility, and thus excellent adhesion when applied to a concrete structure having a stepped region; having excellent heat insulating performance; enabling uniform curing even to the inside of concrete; having remarkably little change in material properties after generating heat; and having excellent durability.
