Problem to be solved

To provide an aluminum pipe support having lighter weight and higher rigidity compared to an iron pipe support.

Solution

An aluminum pipe support 1 is configured with two pieces of pins 2A, an inner pipe 3 having an outer periphery formed in any one of a regular hexagonal shape, a regular octagonal shape, and a regular decagonal shape, and having, at a position not subjected to insertion of the pin 2A, a cross-sectional area of 1.96 times or larger than a cross-sectional area at a corresponding position of an inner pipe of a targeted-size iron pipe support, an outer pipe 2 having an inner shape allowing the inner pipe 3 to be inserted into, and having, at a position not subjected to the insertion of the pin 2A, a cross-sectional area of 1.35 times or larger than a cross-sectional area at a corresponding position of an outer pipe of the targeted-size iron pipe support. The upper limits of the cross-sectional areas of the inner pipe 3 and the outer pipe 2 are set so that the total weight of the inner pipe 3 and the outer pipe 2 is lighter than the total weight of the inner pipe and the outer pipe of the targeted-size iron pipe support.

Effects

The specified load bearing capacity is satisfied, and drastic reduction in weight and high rigidity are achieved.

The present invention relates to a sensor device, system, and monitoring system for monitoring force and inclination of load supporting members, such as temporary support props. The sensor devices include a tubular member that interface with and slidably/detachably attached to the temporary support props, and sensors on the tubular member for measuring force, inclination and position of the temporary support props for construction and demolition work. The sensor device includes a controller for processing data from the sensors. The sensor system includes a wireless device that communicates with the sensor device. The sensor system further comprises positioning device, such that precise location or position of the sensor devices may be detected/calculated by the sensor system. The monitoring system includes a server that communicates one or more sensor systems to form a network.

A formwork system includes (a) a wallform panel for forming a wall portion; and (b) at least one brace assembly including a pair of vertically spaced apart props pivotably connected to the wallform panel for pivoting of the brace assembly relative to the wallform panel between a storage position, in which the brace assembly lies adjacent the wallform panel, and a deployed position, in which the brace assembly projects from the wallform panel for anchoring the props to a ground surface through a common base plate connected to each prop.

A telescopic edge protection post arrangeable between a floor and a ceiling, wherein the telescopic edge protection post comprises an outer tube having a floor end and a top end, and an inner tube having a bottom end and a ceiling end. The inner tube extends into the outer tube and is movable with respect thereto between an extended position and a collapsed position. The post further has a locking mechanism arranged to lock the inner tube with respect to the outer tube, and a tensioning device. The locking mechanism comprises a fixed element, which is attached to the outer tube at its top end, and a movable element, which is movable with respect to the fixed element between a locking position in which the movable element engages with the inner tube and the fixed element to prevent the inner tube from being retracted into the outer tube.

Various implementations described herein are directed to a load bearing ledger fitting, a modular header beam, a perimeter safety deck, a multi-purpose bearing plate, and a mega-shore bearing plate of an integrated construction system.

A surgery table includes a patient support structure coupled to a connection assembly and a base structure coupled to the connection assembly. The connection assembly includes an arm and a locking member that engages the arm. The arm includes spaced apart first and second apertures. The locking member includes spaced apart first and second bores. A first key member and a second key member are included.

A shoring support structure (3) comprising an outer tube (2) having a threaded region (22) with opposing longitudinal slots (16) and an inner tube (4) slidable within the outer tube and having a plurality of pairs of transverse holes (14) at spaced apart intervals. The inner tube and outer tubes terminate in a plate (6) and a pin (10) is receivable through the slots of the outer tube and a pair of transverse holes of the inner tube. A collar (8) is mounted on the threaded region and is rotatable to raise and lower the pin within the slots. The collar includes a driven member (30) such as a bevel gear for mating with a driving member (32) such as a pinion connectable to an actuator (38), actuation of the driving member causing rotation of the driven member to effect rotation of the collar (8) to move the pin.

Disclosed is a prop head for connecting a formwork prop to an elevated concrete slab formwork waler table or the like; said waler table having a plurality of support beams having a cavity or gap space adapted to receive an upper part of said prop head, said table being adapted to receive a bolt across said gap or cavity; wherein said prop head has: a central plate having a front end, a rear end and two sides, said sides having downwardly projecting lower L-shape angle brackets therefrom, said brackets being adapted to receive the top of said prop in a horizontally sliding manner from said front end; a downwardly projecting stop wall from the rear end of said central plate, adapted to abut the upper part of said prop; an upper turret, rising from said lower plate, adapted to fit in said cavity or gap space; and having one or more laterally located slots or holes adapted to correspond with the position of complementary holes or slots in said support beams; and a hole or slot in said central plate adjacent said front end and adapted to receive a locking pin, bolt or wedge thereby to prevent said prop being removed from said brackets. Also disclosed is a method of first securely connecting the prop to a support beam of a waler table and subsequently sliding the T-shaped end of a prop into connection with the prop head and then securing with a locking member.

An indicator for a compression post includes a leg defining an upper end and a lower end, the lower end configured to engage a support plate of the compression post; and an indicator bracket comprising a central portion coupled to the leg at the upper end and an indication portion oriented distal to the leg, the central portion defining a bend extending away from the leg such that the indication portion is laterally offset from the leg, the indicator defining a first visual indicator configured to indicate that the compression post is in either a compressed configuration or an uncompressed configuration.
