The embodiments described below are exemplary and are intended to explain the principles of the present application, and are not to be understood as limiting the present application.

[0021] Referring to Figures 1 to 5 The present application provides a buckling-restrained brace member for seismic resistance of a venue, which comprises a cross-shaped inner core member 101, four first angle steels 102, four second angle steels 103, an outer frame 104, and two end covers 105. Four first angle steels 102 are arranged in the four right-angled corners of the cross-shaped inner core member 101. The outer side wall of each first angle steel 102 is fitted with the inner side wall of the right-angled corner of the cross-shaped inner core member 101 through a hard rubber pad 106. The two ends of each first angle steel 102 extend to the outside of the cross-shaped inner core member 101. The end portions of every two adjacent first angle steels 102 form a first clamping groove 107. The inner side wall of each first angle steel 102 is reversely fitted with a second angle steel 103. The inner side wall of the second angle steel 103 and the inner side wall of the first angle steel 102 form a first concrete cavity 108.

[0022] Two ends of the outer side wall of each second angle steel 103 are provided with wing plates 109, one end of each wing plate 109 is flush with the end of the first angle steel 102, and a second clamping groove 110 is arranged between each wing plate 109 and the corresponding end of the first angle steel 102. The outer frame 104 is clamped on the outside of the four second angle steels 103 and the four first angle steels 102 through cooperation of the first clamping grooves 107 and the second clamping grooves 110. The inner wall of the outer frame 104 and the two wing plates 109 arranged on each second angle steel 103 form a second concrete cavity 111. The end cover 105 is arranged at both ends of the outer frame 104, and the fixing screw 112 is arranged at four corners of the end cover 105. The fixing screw 112 is detachably connected with the outer frame 104.

[0023] In the embodiment, after the four first angle steels 102 are placed inside the four straight angle inclusions of the cross-shaped core member 101, one second angle steel 103 is placed on the inner side wall of each first angle steel 102. Then, the outer frame 104 is clamped on the outside of the four second angle steels 103 and the four first angle steels 102 through cooperation of the first clamping grooves 107 and the second clamping grooves 110. After one end cover 105 is installed at one end of the outer frame 104, concrete is filled outside the first concrete cavity 108 and the second concrete cavity 111. Another end cover 105 is arranged at the other end cover 105 of the outer frame 104, thereby completing the installation of the buckling-restrained brace member. The cross-shaped core member 101, the first angle steel 102, the second angle steel 103, the outer frame 104, and the two end covers 105 in the above structure are all fabricated structures, which can be processed in a factory, and the precision is easy to control, making the on-site construction more convenient.

[0024] Further, the outer frame 104 is composed of four surrounding plates 113. The four surrounding plates 113 are mutually enclosed to form a square structure of the outer frame 104. The inner side wall of each surrounding plate 113 is clamped with the first clamping groove 107 and the second clamping groove 110. The end of each surrounding plate 113 is provided with a threaded hole 114, which is matched with the fixing screw 112. The threaded hole 114 on each surrounding plate 113 corresponds to the threaded hole 114 on the adjacent surrounding plate 113.

[0025] In the embodiment, the four surrounding plates 113 are clamped on the outside of the first angle steel 102 and the second angle steel 103, thereby completing the installation of the outer frame.

[0026] Further, the inner side wall of each of the surrounding plates 113 is provided with a first clamping block 115 and a second clamping block 116, the first clamping block 115 is matched with the first clamping groove 107, and the two sides of the first clamping block 115 are fixedly provided with the second clamping block 116, and the second clamping block 116 is matched with the second clamping groove 110.

[0027] In the embodiment, the surrounding plates 113 are clamped outside the second angle steel 103 and the first angle steel 102 through the first clamping block 115 and the second clamping block 116.

[0028] Further, one end of each of the first clamping blocks 115 away from the corresponding surrounding plate 113 is fitted with the end of the cross-shaped inner core member 101, and one end of each of the second clamping blocks 116 away from the corresponding surrounding plate 113 is fitted with the inner bottom of the second clamping groove 110.

[0029] In the embodiment, one end of each of the first clamping blocks 115 away from the corresponding surrounding plate 113 is fitted with the end of the cross-shaped inner core member 101, and one end of each of the second clamping blocks 116 away from the corresponding surrounding plate 113 is fitted with the inner bottom of the second clamping groove 110, so that the structure of the entire buckling-restrained brace member is more compact and stable.

[0030] Further, each of the end covers 105 comprises a cover plate 117 and a fixed frame 118, the center of the cover plate 117 is provided with a cross-shaped groove 119 matched with the cross-shaped inner core member 101, the cover plate 117 is fitted with the top end of the outer frame 104, and the side of the cover plate 117 close to the outer frame 104 is fixedly provided with the fixed frame 118, and the four end corners of the fixed frame 118 are provided with the fixed screw 112.

[0031] In the embodiment, the fixed frame 118 is fixedly connected with the cover plate 117, and is made by an integral molding technology when the end cover 105 is prepared, so that the structure is more stable.

[0032] Further, the length of the cross-shaped inner core member 101 is greater than the length of the outer frame 104, that is, the two ends of the cross-shaped inner core member 101 protrude out of the two ends of the outer frame 104.

[0033] In the embodiment, since the two ends of the cross-shaped inner core member 101 protrude out of the two ends of the outer frame 104, the installation of the cross-shaped inner core member 101 is facilitated.

[0034] Further, two sides of the interior of each second clamping groove 110 are provided with anti-skid rubber pads 120, and two sides of the second clamping block 116 are in close contact with the anti-skid rubber pads 120.

[0035] In the present embodiment, the structure is more firm when the second clamping plate on the fence 113 is clamped in the interior of the second clamping groove 110 by the provision of the anti-skid rubber pads 120.

[0036] The above disclosure is only a preferred embodiment of the present application, and of course cannot limit the scope of the present application, and those skilled in the art can understand that all or part of the above-mentioned embodiments can be implemented, and equivalent changes made according to the claims of the present application still belong to the scope of the present application.
