Description

Technical Field

[0001] The utility model belongs to the technical field of precast T - beams for bridges, and more specifically, relates to a precast T - beam steel formwork pedestal. Background Technique

[0002] With the rapid development of road engineering construction in China, the construction technology has been continuously matured, the construction standard requirements have become higher and higher, and the construction cost has been continuously increasing. The ecological environment in high - altitude areas is fragile, the geology is complex, and the terrain changes greatly. For road construction projects in high - altitude areas, the environmental conditions are complex, the construction conditions are harsh, and the construction difficulty is relatively large; in highway engineering construction, bridge engineering is an important part, and its superstructure is mostly post - tensioned simply - supported T - beams.

[0003] In the prior art, the material transportation for manufacturing T - beams in high - altitude areas is difficult, the supply and demand of sand and gravel materials do not match, and the material yard insulation is difficult. Moreover, the production efficiency of T - beams in high - altitude areas is low, which affects the overall construction progress and causes economic losses. Currently, before the production of precast T - beams, it is first necessary to set up a temporary pedestal. Due to the surface steel plate material of the traditional integral cement concrete pedestal, the problem of steel plate uplift caused by thermal expansion and contraction due to material differences of the pedestal cannot be solved, which affects the flatness of the beam bottom surface. In addition, the one - time construction cost of the pedestal is relatively high, and a large amount of concrete waste will be generated after the precast T - beams are completed, which affects the environment.

[0004] To solve the above problems, a precast T - beam steel formwork pedestal is proposed in this application. Content of the Utility Model

[0005] Aiming at the problems in the related technology, the utility model proposes a precast T - beam steel formwork pedestal to overcome the above - mentioned technical problems existing in the related prior art.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A precast T - beam steel formwork pedestal includes a base main body. An embedded channel steel is fixedly connected to the top of the base main body. An adjusting plate is attached to the top of the embedded channel steel. A main beam is attached to the top of the adjusting plate. A distribution beam is welded to the top of the main beam. A steel panel is welded to the top of the distribution beam. The main beam is an I - shaped steel, and the distribution beam is a channel steel.

[0008] Preferably, the base main body includes a concrete foundation. Stirrups are arranged inside the concrete foundation. The stirrups are linearly and array - distributed inside the concrete foundation. The inner side wall of the stirrups is fixedly connected with main reinforcement bars.

[0009] By setting the concrete foundation, stirrups and main reinforcement bars, the bearing capacity of the concrete foundation is enhanced through the stirrups and main reinforcement bars, ensuring the structural stability.

[0010] Preferably, the main beams are linearly arrayed on the top of the embedded channel steel, and multiple distribution beams are equidistantly distributed on the top of the main beams.

[0011] By setting the main beams and the distribution beams, the main beams are equidistantly arranged on the top of the embedded channel steel, and multiple distribution beams are welded on the top of multiple main beams, so that the bearing capacity of the pedestal is improved, and the pedestal evenly distributes the load.

[0012] Preferably, fixing holes are formed in the top of the embedded channel steel, and bolts are connected to the embedded channel steel through the fixing holes by threads.

[0013] By setting the bolts and the fixing holes, the adjusting plate and the main beam can be disassembled and installed through the bolts, so that the main beam can be quickly installed on the top of the embedded channel steel and can be quickly disassembled.

[0014] Preferably, a sponge slurry stop belt is fixedly connected to the inner side wall of the distribution beam.

[0015] By setting the sponge slurry stop belt, the sponge slurry stop belt is installed inside the distribution beam with openings facing outwards on both sides of the top of the main beam, so that the sponge slurry stop belt can prevent slurry leakage.

[0016] In summary, the technical effects and advantages of the present utility model are as follows: for the precast T-beam steel pedestal, by linearly arraying the main beams on the top of the embedded channel steel, the length of the steel pedestal can be adjusted according to the number of the main beams, thereby saving the cost investment of the pedestal and saving temporary land. The main beams, the distribution beams and the steel panel are fixed by welding, so that the pedestal has strong reliability and is convenient for installation and disassembly.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] Referring to Figures 1-3 , a precast T-beam steel pedestal includes a base main body 1. An embedded channel steel 2 is fixedly connected to the top of the base main body 1. An adjusting plate 3 is attached to the top of the embedded channel steel 2. A main beam 4 is attached to the top of the adjusting plate 3. A distribution beam 6 is welded to the top of the main beam 4. A steel panel 7 is welded to the top of the distribution beam 6. The main beam 4 is an I-beam, and the distribution beam 6 is a channel steel. The main beam 4 can be leveled by the adjusting plate 3 attached to the bottom of the main beam 4, so that the top of the main beam 4 after installation is horizontal. The main beam 4 made of I-beam makes the pedestal have high bending strength and stiffness. The distribution beam 6 made of channel steel makes the load on the pedestal more evenly distributed to the main beam 4. Therefore, the strength of the pedestal can be effectively improved through the materials and installation structures of the main beam 4 and the distribution beam 6, and the length of the pedestal can be adjusted quickly, avoiding waste of land and saving the investment in temporary land and pedestal cost.

[0024] Referring to Figure 1 and Figure 4 , the base main body 1 includes a concrete foundation 101. Stirrups 102 are arranged inside the concrete foundation 101. The stirrups 102 are linearly and arrayedly distributed inside the concrete foundation 101. A main reinforcement 103 is fixedly connected to the inner side wall of the stirrups 102. By arranging the stirrups 102 and the main reinforcement 103 inside the concrete foundation 101, the spacing of the stirrups 102 is 20 cm, and the stirrups 102 are made of Φ8 steel bars. The main reinforcement 103 fixes a plurality of stirrups 102, and the main reinforcement 103 is made of Φ14 steel bars. Thus, the bearing capacity of the concrete foundation 101 can be effectively enhanced, and the structural stability can be ensured.

[0025] Referring to Figure 1 and Figure 4 , the main beams 4 are linearly and arrayedly distributed on the top of the embedded channel steel 2, and a plurality of distribution beams 6 are equally spaced on the top of the main beams 4. By linearly and arrayedly distributing the main beams 4 on the top of the embedded channel steel 2, and a plurality of distribution beams 6 are equally spaced on the top of the main beams 4, the plurality of distribution beams 6 can be effectively kept horizontal, which can enhance the bearing capacity of the pedestal and make the pedestal evenly distribute the load.

[0026] Referring to Figure 1 and Figure 4, a fixing hole 9 is provided at the top of the embedded channel steel 2, and a bolt 5 is threadedly connected to the embedded channel steel 2 through the fixing hole 9. By adding an appropriate amount of adjusting plate 3 between the embedded channel steel 2 and the main beam 4, the bolt 5 is connected to the embedded channel steel 2, so that the adjusting plate 3 and the main beam 4 are fixed on the top of the embedded channel steel 2. The angle of the main beam 4 is adjusted through the adjusting plate 3, so that the main beam 4 can be effectively kept horizontal, and then the distribution beam 6 can be kept horizontal, avoiding affecting the production of the T-beam.

[0027] Refer to Figures 1-3 , a sponge slurry stop belt 8 is fixedly connected to the inner side wall of the distribution beam 6. By arranging a plurality of distribution beams 6 on the top of the main beam 4, the openings of the distribution beams 6 on both sides face outward, and the sponge slurry stop belts 8 are installed inside the distribution beams 6 on both sides. When the side formwork is closely attached to the base, the gaps can be blocked to avoid slurry leakage.

[0028] Working principle: The base body 1 is made of a concrete foundation 101, stirrups 102 and main reinforcements 103, so that the stirrups 102 and main reinforcements 103 enhance the bearing capacity of the concrete foundation 101, and the embedded channel steel 2 is embedded in the top of the base body 1. The main beam 4 and the adjusting plate 3 are installed on the top of the embedded channel steel 2 through bolts 5, so that the main beam 4 can be quickly disassembled and installed. The main beam 4 can be adjusted through the adjusting plate 3 to keep the main beam 4 horizontal, so that the distribution beam 6 and the steel panel 7 can be kept stable. By installing the sponge slurry stop belt 8 inside the distribution beam 6, slurry leakage is avoided, so that the prefabrication of the T-beam can be effectively carried out.

[0029] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
