Description

Combined high pier capping beam construction support

Technical Field

The utility model relates to a bridge bent cap construction formwork support, concretely relates to modular bent cap construction formwork support system.

Background

Under the condition that the ground support cannot be adopted due to terrain and geological reasons at the bridge position, the construction of the bridge high pier capping beam in mountain and valley areas can adopt a pin rod type, hoop type or bracket type support structure. A hole that runs through the pier stud needs to be reserved to the round pin stick method, and the later stage adopts the concrete to fill, and it is difficult to guarantee to pack the concrete quality, and round cross-section bending resistance effect of round pin stick is not good moreover, and the bearing capacity is not high. By adopting the hoop method, the value of the friction coefficient between the hoop and the pier stud is difficult to master, and the slippage accident of the hoop is easy to occur during construction, so that the bearable load is limited. The bracket method is characterized in that brackets are installed on a pier by means of connecting pieces embedded in a pier body, and although certain influence is caused on the appearance of the pier body, the bracket method is high in bearing capacity, so that the bracket method is frequently adopted in large-volume bent cap construction. No matter above be round pin stick formula, staple bolt formula or cow-leg formula support, because the support is installed at high mound top, no lower part basis supports, does not have construction platform during installation is dismantled, consequently all has the problem of support mounting and dismantlement difficulty.

Disclosure of Invention

The utility model aims to solve the not enough of current bent cap support construction existence, provide one set of be convenient for installation and the combination formula bridge bent cap construction support of dismantling.

The technical scheme of the utility model as follows:

the utility model provides a modular high mound bent cap construction support, installs two brackets through pier shaft built-in fitting respectively in every pier in the same direction as the bridge both sides, and the transverse bridge has set up the spandrel girder to putting up on the bracket of pier with one side, has set up the distribution roof beam on the spandrel girder, installs bent cap construction template, its characterized in that on the distribution roof beam: the bottom of each bracket is connected with an L-shaped hanging bracket, each L-shaped hanging bracket comprises a vertical rod and a cross rod, the vertical rods are tightly attached to the pier body, the upper ends of the vertical rods are connected with the bracket bottom supporting plate through pin shafts, the lower ends of the vertical rods are fixedly connected with one end of the cross rod, and the other end of the cross rod horizontally extends along the direction along the bridge; the vertical rods of the two L-shaped hanging frames on each side of each pier are connected through a cross brace, a plurality of supporting rods are arranged among the cross rods of all the L-shaped hanging frames on the same side of the pier in an overlapping mode, a panel is laid on the supporting rods to form a lower platform, and lower platform guardrails are arranged on the periphery of the lower platform; and a lower crawling ladder leading to the lower platform is arranged at the bottom of the pier along the pier body.

The utility model discloses a modular bent cap construction support, support girder place on supporting the bracket, bear the upper portion load by supporting bracket and built-in fitting jointly, and the bracket below has set up lower platform through L shape gallows, makes things convenient for the workman to install, demolish the bent cap support. The problem of traditional support mounting dismantlement do not have operation platform is solved to can guarantee the work progress safety.

Drawings

Fig. 1 is a schematic view showing a vertical structure of a transverse bridge of the present invention;

fig. 2 is a schematic view of the vertical structure along the direction of the bridge.

Detailed Description

As shown in fig. 1 and 2, in the combined high pier capping beam construction support provided by the present invention, two corbels 2 are respectively installed on two sides of each pier 1 along the bridge direction through pier body embedded parts, a bearing beam 3 is erected on the corbel of the same side of the pier 1 along the transverse bridge direction, a distribution beam 4 is erected on the bearing beam 3, and a capping beam construction template 5 is installed on the distribution beam 4; an L-shaped hanging bracket is connected to the bottom of each bracket 2, and comprises a vertical rod 6 and a cross rod 7. Bracket 2 includes curb plate and roof, and the curb plate is connected with pier shaft built-in fitting, and the roof level sets up, two vertical backup pads of roof bottom welding. The vertical rod 6 is tightly attached to the pier body, the upper end of the vertical rod is positioned between the two support plates of the bracket, a pin shaft is transversely arranged between the two support plates of the bracket and the upper end of the vertical rod, and the vertical rod is connected with the support plate at the bottom of the bracket through the pin shaft; the lower end of the vertical rod 6 is fixedly connected with one end of a cross rod 7, and the other end of the cross rod 7 horizontally extends along the bridge direction. The vertical rods 6 of the two L-shaped hanging frames on each side of each pier are connected through a cross brace 8, a plurality of support rods 9 are erected among the cross rods 7 of all the L-shaped hanging frames on the same side of the pier, a panel is laid on the support rods 9 to form a lower platform, and lower platform guardrails 10 are arranged on the periphery of the lower platform; and a lower ladder 11 leading to the lower platform is arranged at the bottom of the pier along the pier body.

The utility model discloses when the installation, earlier through pier shaft built-in fitting installation bracket 2, after 2 installations of bracket are accomplished, connect L type gallows, set up down the platform bottom the bracket, lower platform sets up the completion back, can carry out support superstructure's installation construction with the help of lower platform.

Support dismantlement after accomplishing for the construction of being convenient for, the utility model discloses install between two corbels tops of every pier every side and fill up roof beam 12, fill up and install wedge on the roof beam 12 and unload frame 13, spandrel girder 3 sets up on the wedge unloads the frame.

In order to ensure the stable integral structure of the support, after the bearing beams 3 are installed, the bearing beams on the two sides of the bridge pier are connected through a plurality of tension rods 14.

The utility model discloses 4 upper berths of distribution beam are equipped with the panel and form the upper mounting plate, and upper mounting plate guardrail 15 is installed to the upper mounting plate periphery. When the bent cap is poured, constructors mainly operate on the upper platform, and can perform auxiliary operations on the lower platform. In order to facilitate the constructors to get on and off the platform, an upper ladder stand 16 is erected between the lower platform and the upper platform.
