Description
Technical Field
The utility model relates to a turnover type system roof beam pedestal belongs to civil construction field.
Background
In the bridge construction field, the beam body prefabrication is indispensable for many bridges, and in the construction of present stage, system beam structure seat adopts masonry structure or concrete structure more, uses big gun hammer to abolish after the construction, and the reconversion soil original state, fertilizer are handled, and this construction method has following shortcoming:
1) the cost is high: the structure seat is a disposable structure, and equipment is needed to be adopted for breaking after construction.
2) Environmental pollution: the removed masonry material can not be recycled as construction waste for treatment.
3) Affected by seasons: the traditional beam-making structure seat adopts a concrete structure or a masonry structure, and construction is influenced by air temperature and rainwater.
4) Non-adjustable: the traditional concrete beam-making structure seat cannot be adjusted after construction is finished, and no effective method is available for adjustment if the size is deviated and is affected by frost heaving.
5) The vibration is inconvenient: the traditional beam-making structure seat is of a solid structure, the vibrating rod cannot go deep into the bottom of the beam, and the attached vibrator needs to be arranged in the core mold, so that the installation and control are inconvenient.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a turnover type system roof beam pedestal, detachable construction makes the pedestal can reuse, has the practicality, and is with low costs, energy-concerving and environment-protective, the construction is easy and make things convenient for the later stage adjustment.
For solving the above problems, the specific technical scheme of the utility model is as follows: the utility model provides a turnover type system beam structure seat is from last to being equipped with pedestal top surface, horizontal bearing structure and vertical bearing structure down in proper order, vertical bearing structure and ground fixed connection, and the lower terminal surface of pedestal top surface passes through the steel band bolt to be connected with horizontal bearing structure up end, and the terminal surface passes through U type card bolt and vertical bearing structure up end fixed connection under the horizontal bearing structure.
The longitudinal section of the transverse supporting structure is of an I-shaped structure.
And the contact structure of the transverse supporting structure and the longitudinal supporting structure is clamped tightly by a U-shaped clamping bolt.
The lower end face of the longitudinal supporting structure is fixedly connected with the ground through an embedded bolt or a fastener.
The utility model discloses the beneficial effect who brings does: the beneficial effect who adopts above scheme: 1. the turnover type beam-making pedestal is bolted and fixed by adopting a steel structure, so that the turnover type beam-making pedestal can be recycled, and can be recycled after the end of scrap; 2. because the scheme can be repeatedly utilized, the construction waste pollution environment can not be generated during the installation and the disassembly; 3. on the premise of finishing foundation treatment, pedestal installation can be carried out in any season, and construction limitation in winter and rain seasons is avoided; 4. if the cross-year use is affected by freezing and thawing, the elevation of the structure can be adjusted; 5. the beam bottom die can be provided with an attached vibrator, so that the vibration quality of the beam body is improved.

Detailed Description
As shown in fig. 1 to 3, a turnover type beam-making pedestal is sequentially provided with a pedestal top surface 1, a transverse supporting structure 2 and a longitudinal supporting structure 3 from top to bottom, the longitudinal supporting structure 3 is fixedly connected with the ground, the lower end surface of the pedestal top surface 1 is connected with the upper end surface of the transverse supporting structure 2 through a steel belt bolt 4, and the lower end surface of the transverse supporting structure 2 is fixedly connected with the upper end surface of the longitudinal supporting structure 3 through a U-shaped clamping bolt 5.
The longitudinal section of the transverse supporting structure 2 is of an I-shaped structure.
The contact structure of the transverse supporting structure 2 and the longitudinal supporting structure 3 is clamped by a U-shaped clamping bolt 5.
The lower end face of the longitudinal supporting structure 3 is fixedly connected with the ground through an embedded bolt or a fastener.
The major structure is divided into three layers, the first layer: the top surface 1 of the pedestal is a beam bottom die which is a steel template; a second layer: the transverse steel supporting structure 2 is made of 18C I-shaped steel; and a third layer: and the longitudinal steel supporting structure 3 is made of 18C I-shaped steel. The steel templates can be properly adjusted according to the specification of the beam body, for example, a 30m box beam is adopted as the beam bottom die, the template is in a form of 1m x 1.5m x 0.05m (width x length x height), the front surface of the template is used as the top surface of the pedestal, and a fixed steel strip is arranged at every 0.5m of the rib part on the back surface of the template and is used for connecting the second layer of transverse I-shaped steel support. The length of the transverse supporting I-steel of the second layer is 1.1m, the number of the transverse supporting I-steel is 31, and the distance between the transverse supporting I-steel and the transverse supporting I-steel is 0.5 m. The second layer passes through steel band bolted connection with the first layer, adopts U type card bolted connection with the third layer, and the vertical steel of third layer supports I-steel length 6m, and quantity 15, every 5 connect into 30 long I-steel through the gusset plate, and root interval 0.45m, the third layer supports and passes through buried bolted connection in advance or adopt the fastener fixed form with ground, and height adjustment adopts the height-adjusting gasket to adjust, adopts the mortar to make level after the adjustment.
After the mounting, a beam-forming pedestal having a height of 41cm, a length of 30m and a width of 1m was formed. According to beam making requirements, the back side of the top surface template of the pedestal can be provided with attached vibrators according to the calculated intervals for vibrating the concrete at the beam bottom. And the side die and the pedestal bottom die are tightly supported and reinforced through the supporting bolt arranged on the second layer of I-steel.
Need carry out the ground reinforcement before the pedestal installation, can install turnover type system roof beam pedestal behind bearing capacity reaches the design requirement. The problem that the quality accident of the box girder is caused due to the uneven settlement of the pedestal caused by insufficient bearing capacity is avoided.
What has been described above is merely a preferred embodiment of the invention. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, several modifications and improvements can be made, and shall be considered as belonging to the protection scope of the present invention.
