Description

Technical Field

[0001] The utility model belongs to the technical field of bridge brackets, and in particular relates to a bridge casting bracket structure for bridge piers. Background Art

[0002] During the suspended cast-in-place construction of a bridge, bridge brackets need to be installed on the piers. The brackets are fixed to the piers and are important structures that support the weight of formwork, supports and concrete extending on both sides of the bridge. Their quality and sturdiness directly affect the quality of bridge construction. Therefore, the installation of brackets is particularly important.

[0003] The Chinese patent with publication number CN220335730U discloses a composite assembled bridge cantilever construction bracket, including a pier body, a support seat and an upper pressure plate. The support seat is provided with a movable groove and a guide groove is arranged in the movable groove. Movable plates are rotatably arranged on both sides of the upper pressure plate. A guide block is rotatably arranged on the other end of the movable plate and the guide block is slidably located in the guide groove. A spring is installed in the guide groove and the other end of the spring is connected to the guide block. A transverse bracket is fixed to the bottom of the support seat, an upper rotating pin is arranged at one end of the transverse bracket and a longitudinal bracket is rotatably connected to the inner side of the upper rotating pin, and a lower rotating pin is rotatably arranged at the lower end of the longitudinal bracket. Thus, the folding and contraction operation of the two groups of brackets can be realized. The structure is simple and the device can be conveniently placed and carried, avoiding the problem of poor operability of welding fixation, and can achieve shock-absorbing and buffering protection effect on the bracket, thereby improving the stability and service life of the bracket during operation.

[0004] However, in actual use, since the telescopic rod is movably inserted into the diagonal support rod, and the diagonal support rod is rotatably connected to the longitudinal bracket, when the telescopic rod is connected to the transverse bracket by fastening bolts, it is necessary to repeatedly adjust the position of the end of the telescopic rod and the length of the telescopic rod relative to the diagonal support rod so that the mounting hole on the telescopic rod is aligned with the mounting hole on the transverse bracket, and the transverse bracket, longitudinal bracket and diagonal support assembly are connected in advance and then connected to the pier body. Also, since the longitudinal bracket can rotate relative to the transverse bracket, it is difficult to control the extended length of the telescopic rod relative to the diagonal support rod, and thus it is difficult to accurately control the overall length of the telescopic rod and the diagonal support rod. In summary, the above-mentioned support structure has poor positioning accuracy during installation and connection, which is not conducive to actual use. Utility Model Content

[0005] The utility model aims to provide a bridge casting bracket structure for bridge piers, so as to solve the problem of poor positioning accuracy of the existing supporting structure during installation and fixing mentioned above.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bridge pier casting bracket structure, comprising

[0007] A cross bracket, the longitudinal section of which is in the shape of "n", an upper mounting seat is fixed to one end of the cross bracket, and a lug is provided at the bottom of the other end of the cross bracket;

[0008] The longitudinal bracket comprises two vertical plates symmetrical to the horizontal bracket, the vertical plates are rotatably mounted on the outer wall of the horizontal bracket close to the upper mounting seat, the lower end of the vertical plates is rotatably mounted with the lower mounting seat, and the side wall of the vertical plates is provided with a vertical slide groove;

[0009] The oblique bracket includes an oblique support plate and a connecting column. One end of the oblique support plate is located on the inner side of the horizontal bracket and is rotatably connected to the lug. An oblique slide groove is provided on the side wall of the oblique support plate. The connecting column is inserted into the oblique slide groove, and both ends of the connecting column extend into the vertical slide grooves on both sides respectively. A connecting plate is fixed to the end of the connecting column.

[0010] The principle and effect of this technical solution:

[0011] 1. By connecting one end of the diagonal support plate to the lug of the horizontal bracket and the other end to the vertical plate through the connecting column, the position and state of the diagonal support can be controlled according to the vertical plate, that is, by setting the vertical slide, the inclined slide and the connecting column, a crank slider mechanism is formed, and the connecting column can drive the vertical plate or the diagonal support plate to move by driving the diagonal support rod or the vertical plate. Therefore, during installation, after the upper mounting seat and the lower mounting seat are fixed on the pier, the position of the diagonal support plate is automatically adjusted to the right position without excessive intervention, and the connecting column is used to limit (cooperate with the vertical slide and the inclined slide at the same time) and bear the load, so that the diagonal support plate can be stably supported.

[0012] 2. By setting the oblique bracket of the main force-bearing member to be solid, the strength of the oblique bracket is improved, and by setting the longitudinal bracket, the force can be transmitted and distributed (in a lifting manner) between the upper mounting seat and the lower mounting seat, avoiding the lower mounting seat bearing the main force while the upper mounting seat is underloaded, making the force more uniform.

[0013] The utility model is further configured as follows: a cross plate is fixed between the two vertical plates, the cross plate is located on a side of the vertical plate close to the lug, and the cross plate is located between the bottom edge of the side of the cross bracket close to the upper mounting seat and the top edge of the vertical slide groove.

[0014] The principle and effect of this technical solution: The setting of the cross-board can make the strength between the two vertical boards higher, and also make the two vertical boards form a whole, which is convenient for management and adjustment.

[0015] The utility model is further configured as follows: the plate thickness at the position on the inclined support plate corresponding to the inclined slide groove is greater than the plate thickness at the position on the inclined support plate where the inclined support plate is rotatably connected to the lug.

[0016] The principle and effect of this technical solution: by increasing the thickness of the diagonal support plate at the inclined slide groove, the strength of the diagonal support plate will not be greatly reduced due to the opening of the inclined slide groove, and the diagonal support plate can be abutted against the inner sides of the two vertical plates, thereby fitting more closely.

[0017] The utility model is further configured as follows: it also includes a reinforcing bracket, the reinforcing bracket includes a guide rail, a slider and a reinforcing plate, the guide rail is installed on the top of the inner side of the cross bracket, the slider is slidably fitted in the guide rail, one end of the reinforcing plate is rotatably installed on the bottom of the slider, and the other end of the reinforcing plate is rotatably installed on the outer wall of the diagonal support plate.

[0018] The principle and effect of this technical solution:

[0019] The utility model is further configured as follows: the reinforcing bracket also includes a limiting bolt, the limiting bolt is threadedly inserted into the top of the transverse bracket, and the end of the limiting bolt extends to the inner side of the guide rail.

[0020] The principle and effect of this technical solution: by setting the limit bolt, the limit bolt can hinder the movement of the slider, thereby locking the position of the reinforcement plate, so that the reinforcement plate can stably stretch and strengthen the diagonal support plate, and when the bracket is in a folded state, it can also prevent the reinforcement plate from unfolding by limiting the movement of the slider, so that the bracket can maintain a stable folded state during transportation.

[0021] The utility model is further configured as follows: the guide groove of the guide rail is T-shaped.

[0022] The principle and effect of the technical solution: the T-shaped guide groove can limit the slider without hindering the normal sliding of the slider.

[0023] The utility model is further configured to include a side pull bracket, which includes a side mounting seat and a side pull plate, one end of the side pull plate is rotatably connected to the outer wall of the cross bracket, and the other end of the side pull plate is rotatably mounted on the side mounting seat.

[0024] The principle and effect of this technical solution: by rotatably connecting the side pull plate with the side mounting seat, the device can rotate the side mounting seat to abut against the outer wall of the cross bracket, thereby reducing space occupancy and facilitating lifting and carrying. By installing the side mounting seat on the outer wall of the pier, the side pull plate can be used to side-pull the cross bracket, thereby avoiding lateral rotation of the cross bracket, making the support structure more stable.
