Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and particularly relates to a trestle platform for construction on the high-slope terrain of a super-large high-speed railway station building. Background Art

[0002] In the construction of super-large high-speed railway station buildings, it is crucial to transport materials and construction machinery efficiently and safely, as well as to carry out construction operations. However, in the actual construction process, there are many challenges in the transportation of materials and construction machinery on a large scale in the station building.

[0003] Under the condition of high-slope terrain, the transportation link is particularly a key point and a difficult point. At present, the common vertical transportation methods mainly rely on tools such as construction hoist elevators, but this method has obvious defects. On the one hand, the installation and use of construction hoist elevators are restricted by various factors such as site conditions and construction progress, and often cannot meet the large-scale and diversified material and construction machinery transportation needs in the construction of the station building. On the other hand, its operation is complex and requires professional personnel for operation and maintenance, increasing the construction cost and management difficulty. The actual application effect is not good and the convenience is relatively low.

[0004] For the construction of steel trestles under the condition of high-slope terrain, there are also many problems. Due to the complex terrain, a large height difference and irregular slopes need to be overcome during the construction process, which greatly increases the difficulty of construction operations. During the construction process, a large amount of earthwork excavation and support work may be required, not only increasing the construction cost, but also having a great impact on the stability of the slope. Once not handled properly, it is extremely easy to cause safety accidents such as slope landslides and collapses, posing a serious threat to the construction.

[0005] With the continuous expansion of the construction scale of super-large high-speed railway station buildings and the continuous development of construction technologies, the demand for construction transportation under the condition of high-slope terrain is becoming increasingly urgent. The current construction methods and technical means are difficult to meet the requirements of efficient, safe and convenient construction. Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the technical problem solved by the utility model is a trestle platform for construction on the high-slope terrain of a super-large high-speed railway station building, which overcomes the defects of insufficient transportation capacity and low convenience of existing vertical transportation tools such as construction hoist elevators in the construction of super-large high-speed railway station buildings on high-slope terrain, realizes efficient, large-scale and diversified transportation of materials and construction machinery, reduces the operation difficulty of steel trestle construction under high-slope terrain, reduces the adverse impact of the construction process on the slope stability, and avoids safety accidents such as slope landslides and collapses caused by construction.

[0007] In order to solve the above problems, the technical solution adopted by the utility model is: a trestle platform for the construction of an extra-large high-speed railway station building on high slope terrain, characterized in that: it includes a portal frame column, there are multiple portal frame columns, and a connecting head is provided on the portal frame column, and a load-bearing longitudinal beam is provided on the connecting head, and the load-bearing longitudinal beam is fixedly connected to the connecting head; multiple portal frame main beams are provided on one side of the load-bearing longitudinal beam, and the portal frame main beams and the portal frame main beams and the portal frame longitudinal beams are fixedly connected by connecting joints; multiple I-beams are provided on the portal frame main beam and are arranged on the portal frame main beam; a bridge panel is provided at the upper end of the I-beam, and the bridge panel is fixedly connected to the I-beam.

[0008] The beneficial effects of this scheme are as follows: the scheme is conducive to improving the stability, safety and economy of the trestle platform construction process under the high slope terrain conditions of the extra-large high-speed railway station building. Compared with the traditional method, the safety and convenience of construction operation are greatly improved; the arrangement of multiple gantry main beams and I-beams greatly improves the bearing capacity of the trestle platform, which can meet the needs of transporting a large amount of materials and machinery at the same time in the construction of extra-large high-speed railway stations, and improves the construction efficiency; the gantry main beams and the gantry main beams and the load-bearing longitudinal beams are fixedly connected by connecting joints, so that when the gantry main beams are hoisted during installation, they are flexible, light, easy to install, and have low space requirements. The gantry main beams are connected by connecting joints, which is convenient for increasing the contact area of ​​welding in the subsequent welding process and improving the stability of welding.

[0009] Furthermore, buffers are arranged between the I-beams, and the buffers are fitted against the I-beams and arranged at intervals between the I-beams. The buffers are arranged between the I-beams and fit against the I-beams and arranged at intervals, which can effectively disperse the load, reduce stress concentration, and make the structure more evenly stressed, thereby enhancing the overall stability of the trestle platform. When the trestle platform is vibrated or impacted, the buffers can absorb and slow down energy transfer, reduce damage to the structure, and extend its service life.

[0010] Furthermore, a monolithic truss is arranged on the portal column, and the monolithic truss is welded to the portal column. The monolithic truss is arranged on the portal column and connected by welding, so that the monolithic truss and the portal column become a whole, which greatly improves the strength and stability of the structure and reduces the risk of deformation or damage of the portal column.

[0011] Furthermore, a fixing seat is provided at the lower end of the portal column. The fixing seat is integrally arranged and can ensure the connection strength and stability between the portal column and the portal column. There is no weak link in the connection part, so that the load borne by the portal column is more evenly transferred to the ground, thereby enhancing the vertical bearing capacity of the column and effectively reducing the possibility of settlement and tilting.

[0012] Furthermore, a connecting rod is provided on the gantry column. The connecting rod is cross-fixed on the gantry column. The cross-fixed connecting rod can enhance the overall rigidity and stability of the gantry column. When the trestle platform is subjected to forces from different directions, such as horizontal wind force, vibration during construction, or uneven loads, the connecting rod can effectively disperse and transfer these forces, avoiding excessive stress concentration at local parts of the column, and reducing the risk of deformation and damage.

[0013] Furthermore, an anti-slip plate is provided on the bridge deck. The anti-slip plate is fixedly connected to the bridge deck, improving the safety of construction workers walking on the bridge deck and reducing the risk of slipping and injury; it can effectively prevent the transported materials and tools from sliding and rolling on the bridge deck, ensuring the smooth progress of construction and reducing losses and delays caused by the slipping of items.

[0014] Furthermore, the connection head is rotationally and cooperatively connected to the gantry column. The angle of the connection head is set to be a structure with fine-tuning. It can better adapt to the irregular changes of the high slope terrain. By fine-tuning the angle of the connection head, the gantry column can maintain a good support state under different terrain conditions, thus ensuring the stability and balance of the entire trestle platform structure. At the same time, it facilitates the construction and installation process, reduces the extra processing and adjustment work due to terrain differences, and improves the construction efficiency.

[0015] Furthermore, the connection joint is an I-beam with an I-shaped structure. The I-beam is arranged at both ends and between the main gantry beams. The I-shaped structure has good bending and torsional resistance performance, can effectively transfer and disperse loads, and enhance the bearing capacity of the connection part. Arranged at both ends of the main gantry beam, it improves the integrity of the entire structure. Using the I-beam connection joint between the main gantry beams can strengthen the cooperative working ability between the main beams, make the loads more evenly distributed on the entire structure, reduce local stress concentration, and the divided main beams are more flexible and convenient during transportation, reducing the transportation difficulty and cost. During hoisting and welding, the space requirements are greatly reduced, and it can better adapt to complex construction environments such as high slope terrains, improving the feasibility and efficiency of construction.

[0016] Furthermore, the gantry longitudinal beam is arranged parallel to the gantry column. Arranging the gantry longitudinal beam parallel to the gantry column enables the gantry longitudinal beam to evenly bear the loads from above and effectively transfer them to the gantry column, avoiding the stress concentration phenomenon caused by unreasonable layout, thereby enhancing the overall bearing capacity and stability of the structure.

[0022] Embodiment 1 is basically as shown in the attached Figures 1-4 drawing: A trestle platform for construction on high-slope terrain of a super-large high-speed railway station building includes gantry columns 3. There are multiple gantry columns 3, and the height of the gantry columns 3 is customized according to the terrain. Two gantry columns 3 are arranged correspondingly. A fixed seat 4 is provided at the lower end of the gantry columns 3. The fixed seat 4 is integrally arranged, so that the load borne by the gantry columns 3 is more evenly transmitted to the ground, enhancing the vertical bearing capacity of the columns and effectively reducing the possibility of settlement and inclination. It is welded and arranged on the gantry columns 3, so that the load borne by the gantry columns 3 is more evenly transmitted to the ground, enhancing the vertical bearing capacity of the columns and effectively reducing the possibility of settlement and inclination. And a single-piece truss 5 is provided on the gantry columns 3, and the single-piece truss 5 is welded to the gantry columns 3.

[0023] A connecting head 1 is provided on the gantry columns 3. The connecting head 1 is rotationally and cooperatively connected with the gantry columns 3. The angle of the connecting head 1 is set to be a structure with fine adjustment, which can better adapt to the irregular changes of the high-slope terrain. By fine-tuning the angle of the connecting head 1, the gantry columns 3 can maintain a good support state under different terrain conditions, thus ensuring the stability and balance of the entire trestle platform structure. At the same time, it facilitates the construction and installation process, reduces the additional processing and adjustment work due to terrain differences, improves the construction efficiency. Parallel load-bearing longitudinal beams 2 are provided on the connecting head 1, and the load-bearing longitudinal beams 2 are fixedly connected to the connecting head 1 by bolts.

These I-beams 7 can enhance the collaborative working ability between the main beams, make the load more evenly distributed on the entire structure, reduce local stress concentration, and make the main beams divided into two parts more flexible and convenient during transportation, reducing the transportation difficulty and cost. During hoisting and welding, the space requirements are greatly reduced, and it can better adapt to complex construction environments such as high-slope terrains, improving the feasibility and efficiency of construction.

The buffer members 8 are arranged in a fitting manner with the I-beams 7. The buffer members 8 are arranged at intervals between the I-beams 7. By arranging buffer members 8 between the I-beams 7 and having the buffer members 8 arranged at intervals in a fitting manner with the I-beams 7, the load can be effectively dispersed, the stress concentration phenomenon can be reduced, and the structure can be more evenly stressed, thereby enhancing the overall stability of the trestle platform.
