Description

Technical Field

[0001] This invention relates to the field of civil engineering construction technology, and to a method for handling the collision between basement supporting lattice columns and the main structure, particularly to a method for handling the collision between basement supporting lattice columns and walls / beams to ensure the smooth construction of the main structure. Background Technology

[0002] Lattice columns are generally composed of steel sections or plates with cross-sections designed to be biaxially or uniaxially symmetrical. They are commonly used as compression-bending members, frequently found in factory building frame columns and independent columns. With the development of the construction industry, underground engineering projects are increasingly common, and internal bracing is a frequent form of support in these projects. Lattice columns are often used as vertical support members in internal bracing systems. However, in actual construction, due to design limitations, the lattice columns used for basement support inevitably collide with the main basement structure. Since these columns cannot be removed, it makes it difficult to construct the structure according to the drawings. This not only significantly impacts construction progress but may also affect the structural safety of the lattice columns, thus compromising construction safety. Currently, addressing this issue primarily involves reinforcement design based on specific circumstances, without a standardized operational plan.

[0003] Therefore, developing a safe and standardized method for handling collisions between basement support lattice columns and the main structure that has minimal impact on construction progress is of great practical significance. Summary of the Invention

[0004] Due to the aforementioned deficiencies in existing technologies, this invention provides a safe and standardized method for handling collisions between basement support lattice columns and the main structure that has minimal impact on construction progress. This method addresses the problems of existing solutions lacking uniformity and standardization, having poor safety, and significantly affecting construction progress.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A method for handling the collision between the basement support lattice column and the main structure involves marking the collision location and form of the lattice column and the main structure according to the foundation pit support and basement structure construction drawings before construction. During the construction of the main structure, the main structure is enlarged at the collision location between the lattice column and the main structure so that the lattice column is wrapped by the enlarged main structure. At the same time, reinforcement is added at the collision location during the rebar binding stage to enhance the structural strength.

[0007] The method for handling collisions between basement support lattice columns and the main structure in this invention has a relatively simple overall procedure. It provides a unified and standardized method for handling collisions between basement support lattice columns and the main structure, which can ensure the safety of the support while ensuring the smooth construction of the main structure. That is, it ensures both construction progress and construction safety, and has great application prospects.

[0008] As a preferred technical solution:

[0009] The method for handling the collision between the basement supporting lattice column and the main structure, as described above, comprises the following steps:

[0010] (1) Based on the construction drawings of the foundation pit support and basement structure, mark the collision position and form between the lattice column and the existing structure;

[0011] (2) Chisel and clean the concrete inside the lattice columns at the construction site;

[0012] (3) The site was leveled by excavation in the foundation pit. After reaching the design elevation, mortar spots were placed and the foundation concrete was poured.

[0013] (4) Foundation slab brick formwork construction, reinforcement binding, and concrete pouring;

[0014] (5) Tie the wall and column reinforcement. The wall and beam of the lattice column must be reinforced and fixed according to the position of the corresponding lattice column touching the wall and beam. Before the formwork is sealed, the foundation slab wall and column base should be roughened and cleaned. Concrete can be poured only after the debris inside the formwork is cleaned.

[0015] (6) While the main structure is being constructed, the replacement beams are being constructed in accordance with the construction drawings;

[0016] (7) When the main structure and the replacement beams reach the design strength, the support beams and lattice columns are removed, and the exposed steel of the lattice columns is coated with anti-rust paint.

[0017] As described above, in the method for handling the collision between the basement support grid column and the main structure, in step (5), the wall and beam that collide with the grid column must be reinforced according to the position of the grid column colliding with the wall and beam. Specifically, this means reinforcing according to the collision form between the grid column and the existing structure.

[0018] The above-described method for handling collisions between basement supporting lattice columns and the main structure includes collisions between the lattice columns and existing structures, collisions between the lattice columns and walls, partial collisions between the lattice columns and beams, complete collisions between the lattice columns and beams, and partial oblique collisions between the lattice columns and beams.

[0019] As described above, a method for handling the collision between a basement support grid column and the main structure is described. The collision between the grid column and the existing structure occurs when the grid column collides with the wall. Specifically, the reinforcement involves adding longitudinal main bars around the grid column and fixing the longitudinal main bars with stirrups. The stirrups are U-shaped stirrups. The enlargement of the main structure at this point is to enlarge the wall locally and enclose the grid column in the inner wall.

[0020] The collision mode between the lattice column and the existing structure is when the lattice column and the beam collide locally. The reinforcement is specifically to add open-type steel bars on the outside of the beam of the lattice column that extends beyond the beam area. The open-type steel bars surround the lattice column inside the beam and open towards the side of the beam that is not locally enlarged. The enlargement of the main structure at this point is to make a local enlargement treatment on the outside of the beam of the lattice column that extends beyond the beam area, so that the lattice column that extends beyond the beam area is wrapped in the beam.

[0021] The collision form between the lattice column and the existing structure is when the lattice column completely collides with the beam, that is, when both sides of the lattice column exceed the cross section of the beam. The reinforcement specifically involves adding open-type steel bars on both sides of the lattice column that exceed the cross section of the beam. The open-type steel bars surround the lattice column inside the beam. The enlargement of the main structure at this point is to enlarge both sides of the lattice column that exceed the cross section of the beam, so that the lattice column is wrapped in the beam.

[0022] The collision between the lattice column and the existing structure is when the lattice column and the beam collide locally at an oblique angle. The reinforcement specifically involves adding straight vertical steel bars to the outside of the lattice column on the outside of the beam. The enlargement of the main structure at this point is that the lattice column is enlarged on the outside of the beam, and the lattice column is wrapped inside the beam.

[0023] This invention provides the above standard operating procedure for handling the collision between the basement supporting lattice column and the main structure. When faced with this problem, those skilled in the art can complete the handling of the collision between the basement supporting lattice column and the main structure by following the above standard procedure. The above method does not affect the structural safety of the basement supporting lattice column, thus ensuring the safety of construction.

[0024] The above invention has the following advantages or beneficial effects:

[0025] The method for handling collisions between basement support lattice columns and the main structure in this invention has a relatively simple overall procedure. It provides a unified and standardized method for handling collisions between basement support lattice columns and the main structure, which can ensure the safety of the support while ensuring the smooth construction of the main structure. That is, it ensures both construction progress and construction safety, and has great application prospects. Attached Figure Description

[0032] The structure of the present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0033] Example 1

[0034] A method for handling the collision between the basement supporting lattice columns and the main structure was specifically applied in the construction of the basement structure of the Sun Hotel in the Nanxun Ancient Town Tourism Service Supporting Improvement Project (Phase I). The steps are as follows:

[0035] (1) Based on the construction drawings of the foundation pit support and basement structure, mark the collision position and form between the lattice column and the existing structure;

[0036] (2) Chisel and clean the concrete inside the lattice columns at the construction site;

[0037] (3) The site was leveled by excavation in the foundation pit. After reaching the design elevation, mortar spots were placed and the foundation concrete was poured.

[0038] (4) Foundation slab brick formwork construction, reinforcement binding, and concrete pouring;

[0039] (5) Tie the reinforcing bars of the walls and columns. The walls and beams that collide with the lattice columns must be reinforced and fixed according to the corresponding positions of the lattice columns that collide with the walls and beams (reinforcement is carried out according to the collision form of the lattice columns with the existing structure (collision between the lattice columns and the walls, partial collision between the lattice columns and the beams, complete collision between the lattice columns and the beams, and partial oblique collision between the lattice columns and the beams)). Before the formwork is sealed, the foundation slab walls and column roots are roughened and cleaned. Concrete can only be poured after the debris inside the formwork is cleaned.

[0040] (6) While the main structure is being constructed, the replacement beams are being constructed in accordance with the construction drawings;

[0041] The collision between the lattice column and the existing structure occurs when lattice column 1 collides with wall 4. Specifically, reinforcement involves adding longitudinal main bars 2 around lattice column 1, and simultaneously using stirrups 3 (U-shaped stirrups 3.1) to fix the longitudinal main bars 2. The presence of stirrups 3 provides shear resistance. Enlarging the main structure at this point involves locally enlarging the wall, enclosing the lattice column within the wall, such as... Figure 1 As shown;

[0042] The collision between the lattice column and the existing structure occurs when the lattice column 1 and beam 6 experience a partial collision. The reinforcement specifically involves adding open-type steel bars 5 to the outside of the beam of the lattice column extending beyond the beam area. These open-type steel bars 5 enclose the lattice column 1 within the beam 6, and open towards the side of the beam that is not locally enlarged. The enlargement of the main structure at this point is essentially a partial enlargement of the outside of the beam of the lattice column extending beyond the beam area, enclosing the lattice column 1 extending beyond the beam area within the beam 6. Figure 2 As shown;

[0043] The collision between the lattice column and the existing structure occurs when the lattice column 1 completely collides with beam 6, meaning both sides of the lattice column extend beyond the beam's cross-section. The reinforcement specifically involves adding two open-type steel bars 5 to both sides of the lattice column extending beyond the beam's cross-section. These two open-type steel bars 5 enclose the lattice column 1 within beam 6. The enlargement of the main structure at this point involves enlarging both sides of the lattice column extending beyond the beam's cross-section, effectively enclosing the lattice column 1 within beam 6. Figure 3 As shown;

[0044] When the collision between the lattice column and the existing structure occurs as a local oblique collision between the lattice column 1 and beam 6, the reinforcement specifically involves adding straight vertical steel bars 7 to the lattice column on the outside of the beam. The enlargement of the main structure at this point is achieved by enlarging the lattice column on the outside of the beam, effectively enclosing the lattice column 1 within beam 6. Figure 4 As shown;

[0045] (7) When the main structure and the replacement beams reach the design strength, the support beams and lattice columns are removed, and then the exposed steel of the lattice columns is coated with anti-rust paint.

[0046] In summary, the method for handling collisions between basement support lattice columns and the main structure of the present invention has a relatively simple overall procedure, providing a unified and standardized method for handling collisions between basement support lattice columns and the main structure. It can ensure the safety of the support while ensuring the smooth construction of the main structure, thus ensuring both construction progress and construction safety, and has great application prospects.
