The cross section of the arc piece 25 is rectangular, the side wall of the arc piece 25 is attached to the inner wall of the through hole 221, and after the arc piece 25 penetrates through the through hole 221, the through hole 221 is closed by the arc piece 25.
Initially, the cover plate 32 of the bracket 3 is firstly connected to the steel beam 2 in a rotating mode, and when the cover plate 32 provides an installation position for the arc piece 25, the constructor can conveniently control the rotation of the arc piece 25. The position of the cover plate 32 is controlled by a constructor, so that the free end of the arc piece 25 is temporarily retracted into the cavity 23, the through hole 221 is opened at the moment, the constructor injects cement slurry into the cavity 23 through the through hole 221, then the cover plate 32 is rotated to enable the cover plate 32 to be attached to the adjacent wing plate 22, and at the moment, the free end of the arc piece 25 penetrates out of the closed through hole 221 of the cavity 23 to prevent the cement slurry from leaking through the through hole 221. Then constructor hoists the steel beam 2 to the installation position on the stand 1, after the tip of steel beam 2 is fixed on the stand 1, constructor rotates the apron 32 again, make the apron 32 rotate to the position of butt joint with backup pad 31, circular arc 25 follows the apron 32 and rotates, the free end of circular arc 25 retracts into cavity 23 again and breaks away from with through-hole 221, through-hole 221 opens this moment, refer to fig. 3, the grout in the cavity 23 begins to discharge through-hole 221, the grout then gathers in the space that is enclosed by apron 32, two backup pads 31, accept board 34 and stand 1 under through-hole 221, it can to wait for the grout to solidify afterwards. In this a scheme for constructing bracket 3, backup pad 31, accept board 34 and apron 32 solidify the fashioned template as grout, have saved constructor and have set up the template on stand 1, and the grout that is used for pouring bracket 3 simultaneously is stored in steel crossbeam 2, when realizing that the installation of steel crossbeam 2 is fixed, still can accomplish the construction of the cast-in-place part of bracket 3, has avoided the inconvenience of cast-in-place in high altitude, and then has made things convenient for the operation of construction bracket 3.
Referring to fig. 2, a flow guiding block 26 is further disposed in the cavity 23, the flow guiding block 26 is fixed on the wing plate 22 with the through hole 221, two sides of the flow guiding block 26 are respectively abutted to the adjacent side plates 211, and the arc piece 25 simultaneously rotates to pass through the flow guiding block 26. The side wall of the flow guide block 26, which is not connected with the wing plate 22, is inclined downwards towards the through hole 221, so that the inclination degree of the bottom of the cavity 23 is increased by the flow guide block 26 when the steel beam 2 is in the installation position, cement slurry can flow to the through hole 221 more easily, and the residue of the cement slurry in the cavity 23 can be reduced.
Referring to fig. 3, two sides of the cover plate 32 are fixedly connected with an ear plate 321, and each ear plate 321 is provided with a fixing bolt 33 in a penetrating manner. When circular arc piece 25 is in the position of closed through-hole 221, apron 32 and adjacent pterygoid lamina 22 laminating, at this moment, adjacent pterygoid lamina 22 can be worn to establish by the screw thread to fixing bolt 33, and constructor can fix the position of apron 32 through screwing fixing bolt 33 on pterygoid lamina 22, and circular arc piece 25 alright continue closed through-hole 221, and at the in-process of installation steel crossbeam 2, grout will be difficult to take place to leak through-hole 221.
Referring to fig. 3, a fixing block 311 is fixedly connected to a side wall of the two support plates 31 opposite to each other, when the cover plate 32 rotates to a position where the cover plate abuts against the support plates 31, the two ear plates 321 on two sides of the cover plate 32 respectively face the fixing block 311 on the same side, and the fixing bolt 33 can penetrate through the fixing block 311. The constructor will follow the fixing bolt 33 that pterygoid lamina 22 went down, wear to establish again the otic placode 321 and the fixed block 311 of the homonymy, so can fix the position when apron 32 and backup pad 31 butt, alright later on the solidification of the grout takes shape. Caulking grooves 312 are formed in the side edges, abutted to each supporting plate 31 and the cover plate 32, of the cover plate 32, the side edges of the cover plate 32 are embedded into the caulking grooves 312 in the supporting plate 31 on the same side through the rotation of the cover plate 32, the abutting of the cover plate 32 and the supporting plate 31 is achieved, the contact area of the cover plate 32 and the supporting plate 31 can be increased through the caulking grooves 312, and therefore the probability of leakage of cement slurry between the cover plate 32 and the supporting plate 31 is reduced.
It should be noted that, when the cover plate 32 is rotated to the position of abutting against the support plate 31, in order to ensure that the cement can be smoothly discharged from the through hole 221, the arc length of the arc member 25 needs to be such that the free end of the arc member 25 is retracted into the cavity 23 before the cover plate 32 abuts against the support plate 31, and accordingly, when the cover plate 32 does not fully abut against the support plate 31, the cement is retained through the through hole 221, the vertical projection of the through hole 221 falls on the receiving plate 34, and the receiving plate 34 is used for receiving the part of the cement paste flowing out in advance, thereby reducing the waste of the cement paste.
The implementation principle of the embodiment of the application is as follows: the support plate 31 of the bracket 3 is pre-embedded on the upright post 1 when the upright post 1 is constructed, and cement paste for pouring the bracket 3 is pre-stored in the steel beam 2.
