Technical Field

[0001] This utility model relates to the field of building construction technology, and specifically to a column base structure for installing guardrail posts. Background Technology

[0002] In construction projects, edge protection is an important safety measure, typically achieved by erecting edge guardrails using columns and horizontal bars. However, to ensure the stability of the columns, it is usually necessary to pre-embed or use expansion bolts to fix the column base structure to the ground. This method is time-consuming, labor-intensive, and cumbersome to dismantle. Utility Model Content

A fixing plate is set at the corner platform of the stairs, and a connecting column is set on the fixing plate to connect the column. The fixing plate is limited by the upper and lower hanging plates abutting against the treads of the upper and lower stairs.

[0004] The technical solution to achieve the above objective is a column base structure for installing guardrail posts, installed on a stair corner platform. An upper run of stairs and a lower run of stairs are connected to the side of the stair corner platform, and the upper and lower runs of stairs are located on the same side of the stair corner platform. The column base structure includes:

[0005] A fixing plate is installed on the top of the staircase corner platform;

[0008] The upper hanging plate is disposed on the side of the fixing plate and is attached to the edge of the step of the upper run of the stairs.

[0009] Furthermore, a fixed foot plate is vertically installed on the lower hanging plate, and an adjustable rod is installed on the fixed foot plate. A portion of the adjustable rod extends towards the bottom of the upper staircase to form a limiting section. A limiting plate is fixed to the limiting section, and the limiting plate is attached to the bottom of the upper staircase.

[0010] Furthermore, the limiting plate is L-shaped, with one side of the limiting plate attached to the bottom of the upper run of the stairs, and the other side of the limiting plate attached to the side of the upper run of the stairs.

[0011] Furthermore, an adjustment groove is formed on the fixed foot web plate, the adjustment groove is opened along the height direction of the fixed foot web plate, and the adjustment rod is slidably disposed in the adjustment groove.

[0012] Furthermore, the adjusting rod is threaded with two adjusting nuts, the size of which is larger than the size of the adjusting groove. The two adjusting nuts are respectively located on both sides of the fixed foot plate. By screwing the adjusting nuts, the two adjusting nuts clamp the fixed foot plate to fix the adjusting rod.

[0013] Furthermore, the height of the fixed foot plate is adapted to the height of the descending stairs.

[0014] Furthermore, the length of the adjusting rod is determined according to the on-site construction requirements.

[0015] Furthermore, a baffle is provided on the side of the lower hanging plate away from the upper hanging plate, and the baffle is located near the bottom of the lower hanging plate.

[0016] Furthermore, the length of the lower hanging plate is adapted to the height of the treads of the lower staircase.

[0017] Furthermore, the length of the upper hanging plate is adapted to the height of the treads of the upper staircase.

[0018] Compared with the prior art, this utility model has the following advantages:

[0019] A fixing plate is installed at the landing of the staircase, and a connecting column is installed on the fixing plate to connect the column. The fixing plate is limited by the upper and lower hanging plates abutting against the treads of the upper and lower run of the staircase. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] See Figure 1A column base structure for installing guardrail posts is provided on a stair corner platform 9. An upper run staircase 10 and a lower run staircase 11 are connected to the side of the stair corner platform 9. The upper run staircase 10 and the lower run staircase 11 are located on the same side of the stair corner platform 9. The column base structure includes: a fixing plate 1 located on the top of the stair corner platform 9; a connecting column 2 fixed to the top of the fixing plate 1 and for connection with a column 8; a lower hanging plate 6 located on the side of the fixing plate 1 and attached to the tread edge of the lower run staircase 11; and an upper hanging plate 3 located on the side of the fixing plate 1 and attached to the tread edge of the upper run staircase 10.

[0026] In this utility model, a preferred embodiment is as follows: the column base structure is set in the middle of the stair corner platform 9. The lower hanging plate 6 is attached to the edge of the step of the lower run of the stair 11, and the upper hanging plate 3 is attached to the edge of the step of the upper run of the stair 10 to limit the column base structure and prevent the column 8 from shaking during use. Then the column 8 is fixed on the stair corner platform 9. When dismantling, the connecting column 2 and the column 8 can be removed first, and then the connecting column 2 can be slid away from the upper run of the stair 10 to remove it.

[0027] Furthermore, the upper hanging plate 3 and the lower hanging plate 6 are made of steel plates.

[0028] Furthermore, the column 8 and the connecting column 2 can be fixed together by bolts or threads.

[0029] Furthermore, a fixed foot plate is vertically installed on the lower hanging plate 6, and an adjusting rod 5 is adjustable on the fixed foot plate. A portion of the adjusting rod 5 extends towards the bottom of the upper staircase 10 to form a limiting section. A limiting plate 4 is fixed to the limiting section and fits against the bottom of the upper staircase 10. Preferably, a lower external corner is formed at the bottom of the upper staircase 10, and the baffle 7 is engaged at this lower external corner.

[0030] Furthermore, the limiting plate 4 is L-shaped, with one side of the limiting plate 4 fitting against the bottom of the upper run of the staircase 10 and the other side fitting against the side of the upper run of the staircase 10. In use, the L-shaped limiting plate 4 is used to lock the lower external corner of the upper run of the staircase 10 to further limit the column base structure.

[0031] Furthermore, an adjustment groove is formed on the fixed foot plate, the adjustment groove being opened along the height direction of the fixed foot plate, and the adjustment rod 5 is slidably disposed within the adjustment groove. In use, the position of the adjustment rod 5 can be adjusted by sliding the adjustment rod 5 along the height direction of the adjustment groove, so that the limiting plate 4 is engaged at the lower external corner of the upper runway 10.

[0032] Furthermore, the adjusting rod 5 is threaded with two adjusting nuts, the size of which is larger than the size of the adjusting groove. The two adjusting nuts are respectively located on both sides of the fixed foot plate. By screwing the adjusting nuts, the two adjusting nuts clamp the fixed foot plate to fix the adjusting rod 5.

[0033] Furthermore, the height of the fixed foot plate is adapted to the height of the downstairs staircase 11.

[0034] Furthermore, the length of the adjusting rod 5 is determined according to the on-site construction requirements.

[0035] Furthermore, a baffle 7 is provided on the side of the lower hanging plate 6 away from the upper hanging plate 3, and the baffle 7 is provided near the bottom of the lower hanging plate 6.

[0036] Furthermore, the length of the lower hanging plate 6 is adapted to the height of the treads of the lower runway 11.

[0037] Furthermore, the length of the upper hanging plate 3 is adapted to the height of the treads of the upper running stairs 10.

[0038] The following describes the usage process of the column base structure for installing a guardrail post according to this utility model.

[0039] The column base structure is set in the middle of the stair landing platform 9. The lower hanging plate 6 is attached to the edge of the step of the lower run of the stairs 11, and the upper hanging plate 3 is attached to the edge of the step of the upper run of the stairs 10 to limit the column base structure and prevent the column 8 from shaking during use. Then the column 8 is fixed to the stair landing platform 9. When dismantling, the connecting column 2 and the column 8 can be removed first, and then the connecting column 2 can be slid away from the upper run of the stairs 10 to remove it.
