The invention discloses anovel inner octagonal bolt frame structure joint and a construction method. Thenovel inner octagonal bolt frame structure joint includesa steel column and a square steel tube,the steel column sleeves the square steel tube, thenthe steel column and the square steel tube are placed on a bolt sleeve with a hole, the steel column and the outer side of the square steel tube are connected with an H-shaped belt end plate steel beam to form a whole through anoctagonal bolt. According to the novel inner octagonal bolt frame structure joint and the construction method, the disadvantages that the bearing capacity is reduced due to opening forming iscompensated by reinforcing a beam-column joint, the stability of the joint isimproved, the novel inner octagonal bolt frame structure jointhas the advantages that frame arrangement isflexible, installation issimple, construction process issimple, the manufacturing quality of parts is easy to ensure, and the site installation connection is facilitated;and the inner octagonal sleeve is placed inside the joint, and the problems that the bolt is complex to be connected at the joint and a nut is complex to be installed inside are solved.

A two-dimensional fast deflection table integrating a sensing unit and a constraint element, and a method. The deflection table comprises X-axis and Y-axis angular displacement sensing measurement devices (3, 4) which are located between a micro-angle pendulum platform 1 and a base 2, a double-axis flexible hinge 10 being arranged on the lower surface of the micro-angle swinging platform; and the deflection table also comprises four linear voice coil motors (6, 7, 8, 9); the X-axis and Y-axis angular displacement sensing measurement devices (3, 4) each comprise a pair of flexible metal beams (3-1, 3-2) projecting from two opposite sides of a rigid support 5 and mass blocks (3-3, 3-4) which are fixedly connected to the tail ends of the flexible metal beams (3-1, 3-2); a strain gauge is attached to upper and lower surfaces near the root of each flexible metal beam (3-1, 3-2); the first and third voice coil motors (6, 7) are oppositely arranged using the same specifications and form a first actuator set; the second and fourth voice coil motors (8, 9) are oppositely arranged using the same specifications and are perpendicular to the first actuator set in a cross arrangement; With the present invention, the constraining rigidity of the deflection table is increased by means of the flexible metal beams; meanwhile, the deflection table serves as a sensing unit for performing real-time measurement of double-axis deflection angles in a strain feedback mode.
