Examples
Referring to fig. 3 and 4, the fixing device 001 for the cast-in-place arch bridge formwork in the present embodiment includes a body frame 100 and an expansion frame 200, and the body frame 100 itself may be directly used to support an end mold of the arch bridge formwork. And it is great at some end mould, perhaps can increase expansion frame 200 when end mould upper end operation platform need be provided after the end mould supports, provide the additional support of end mould or operation platform's installation basis through expansion frame 200.
Referring to fig. 1, in particular, the body frame 100 includes a brace 110, a fixing rod 130 and a reinforcing diagonal brace 150, and the brace 110, the fixing rod 130 and the reinforcing diagonal brace 150 are all # 10 angle steels, which are low in cost but have sufficient strength to provide sufficient safety performance. The stay bar 110 is vertically and fixedly connected with the fixed rod 130, and a reinforcing inclined strut 150 is fixedly arranged between the stay bar 110 and the fixed rod 130; one surface of the stay bar 110 far away from the fixing bar 130 is provided with an end mold abutting piece; the end mould abutment comprises a rubber plate 111.
The rubber sheet 111 can be used to softly contact the end mold to prevent damage to the end mold. In other embodiments, the end mould abutments may also comprise air bubble concrete, increasing the amount of resilience of a portion whilst ensuring strength.
Referring to fig. 2, in the present embodiment, the expansion bracket includes a first expansion rod 210 for coaxial connection with the stay rod 110, and a second expansion rod 230 for coaxial connection with the fixing rod 130; a connection brace 250 is fixedly arranged between the first expanding rod 210 and the second expanding rod 230.
The first expanding rod 210 is used for expanding the length of the supporting rod 110, the second expanding rod 230 is used for supporting the first expanding rod 210, the stability of the whole fixing device is improved, and the connecting inclined strut 250 is used for enabling the first expanding rod 210 and the second expanding rod 230 to form an integral necessary connecting piece on one hand and transmitting the stress of the first expanding rod 210 to the second expanding rod 230 to realize the force dispersion on the other hand.
In this embodiment, the angle between the connecting diagonal brace 250 and the second expanding rod 230 is equal to the angle between the reinforcing diagonal brace 150 and the fixing rod 130. The dowel bar 270 is fixedly arranged on the connecting inclined strut 250, one end, far away from the connecting inclined strut 250, of the dowel bar 270 is used for being in contact fit with the reinforcing inclined strut 150, and the dowel bar 270 and the connecting inclined strut 250 are vertically arranged.
In this way, the force transmission rod 270 is perpendicular to the connecting inclined strut 250 and the reinforcing inclined strut 150 at the same time, and the force transmission rod 270 is prevented from being separated from the connecting inclined strut 250 due to excessive local stress caused by the axial misalignment of the force transmission rod and the force transmission rod.
