Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a construction protection frame for a building adjacent structural column and a construction method thereof. Background Art

[0002] Structural columns are also called structural columns. In order to enhance the integrity and stability of the building, reinforced concrete structural columns should be installed in the walls of multi-story brick-concrete structures and connected to the ring beams of each floor to form a spatial frame that can resist bending and shearing. It is an effective measure to prevent the collapse of houses.

[0003] During the construction process of a building project, many structural columns will be constructed, and the edge structural columns refer to the structural columns close to the outer edge. During the construction process, many guardrails will be built for construction protection.

[0004] However, the height of the guardrail is generally low. When construction is carried out at a high place adjacent to the structural column, the guardrail cannot play an effective protective role. It is necessary to build a temporary construction protection frame near the adjacent structural column. However, there are many similar adjacent structural columns. It would be too cumbersome if each adjacent structural column needs to be built during construction. Therefore, we proposed a construction protection frame for building adjacent structural columns and a construction method thereof. Summary of the invention

[0020] The construction method of the protective frame for the construction of the building adjacent structural column comprises the following steps:

[0021] S1.

[0022] S2. At this time, the two movable square tubes can be pulled toward each other or pushed to move in the opposite direction according to the width of the adjacent structural column, until the two first support bars are respectively located on both sides of the adjacent structural column, and then the pull rod is released, and under the action of multiple reset springs, the two limit blocks are reinserted into the two limit holes on the front side of the movable bar, thereby fixing the positions of the movable square tube, the movable bar, the first fixed bar and the first support bar;

[0023] S3, then push the two protective members to rotate outward respectively, so that the two protective members are in a vertical state with the first fixing bar and the first supporting bar, and then rotate the screw rods on the front side of the supporting square tube on both sides respectively, so that the screw rods rotate inside the nut seat, thereby driving the positioning plate at the end of the screw rod to rotate toward the side wall of the adjacent structural column, until the positioning plate is tightly fitted with the side wall of the adjacent structural column, thereby fixing the position of the fixing member and the two protective members;

[0024] S4. When it is necessary to protect the higher positions on both sides of the adjacent structural columns, the reset rod is pulled outward to drive the short positioning rack to move toward the positioning block, so that the short positioning rack is separated from the long limiting rack and the positioning spring is compressed. At this time, the top rod can be pulled upward to drive the two protection bars and multiple protection bars at the bottom of the top rod to move upward. At this time, they can be moved to a suitable height according to the floor height, and then the reset rod is released. Under the action of the positioning spring, the short positioning rack and the long limiting rack are re-engaged, so that the position of one of the protection bars can be fixed, and then the two protection bars and the multiple protection bars can be fixed at the same time. The two protection bars and the multiple protection bars can play an effective protective role, which is convenient for construction personnel to carry out construction;

[0025] S5. When it is necessary to construct other adjacent structural columns, it is only necessary to rotate the screw rod in the opposite direction to separate the positioning plate from the side wall of the adjacent structural column, and then the positions of the fixing parts and the two protective parts can be moved to carry out construction protection on other adjacent structural columns;

[0026] S6. After the construction is completed, pull the reset rod again so that the two protection bars and multiple protection bars can slide downward, so that the two protection bars and multiple protection bars can enter the interior of the two supporting square tubes and multiple supporting sleeves, and then pull the pull rod outward so that the two movable square tubes can move toward each other, and then pull the two protection parts to rotate toward the fixed parts, thereby greatly reducing the space occupied by the equipment and facilitating storage and transportation.

[0027] The invention discloses a construction protection frame for a building adjacent structural column and a construction method thereof, which has the following beneficial effects:

[0028] 1. The protective frame for the construction of the adjacent structural columns of the building and the construction method thereof can pull the two movable square tubes to move toward each other or push the two movable square tubes to move oppositely according to the width of the adjacent structural column, so that the two first support bars are respectively located on both sides of the adjacent structural column, so that the positioning plate is tightly fitted with the side wall of the adjacent structural column, thereby fixing the positions of the fixing member and the two protective members; the two protective strips and multiple protective rods at the bottom of the top rod are driven to move upward, and at this time, they can be moved to a suitable height according to the floor height, and then the reset rod is loosened, and under the action of the positioning spring, the short positioning rack and the long limiting rack are re-engaged, and then the two protective strips and the multiple protective rods are fixed at the same time, so that the two protective strips and the multiple protective rods can play an effective protective role, which is convenient for construction personnel to carry out construction.

[0029] 2. The protective frame for the construction of the adjacent structural columns of the building and the construction method thereof, when it is necessary to carry out construction on other adjacent structural columns, it is only necessary to rotate the screw rod in the reverse direction to separate the positioning plate from the side wall of the adjacent structural column, and then the positions of the fixing parts and the two protective parts can be moved to carry out construction protection on other adjacent structural columns.

Under the action of the positioning spring (506), the short positioning rack (505) and the long limiting rack (504) are re-engaged, thereby fixing the position of one of the protection strips (501), and then fixing the two protection strips (501) and the multiple protection rods (502) at the same time. The two protection strips (501) and the multiple protection rods (502) play an effective protective role, which is convenient for construction personnel to carry out construction; S5. When it is necessary to carry out construction on other adjacent structural columns, it is only necessary to rotate the screw rod (401) in the opposite direction to separate the positioning plate (402) from the side wall of the adjacent structural column, thereby moving the position of the fixing member (1) and the two protection members (2) to carry out construction protection on other adjacent structural columns; S6. After the construction is completed, the reset rod (507) is pulled again to make the two protection bars (501) and the multiple protection bars (502) slide downward, so that the two protection bars (501) and the multiple protection bars (502) enter the interior of the two supporting square tubes (203) and the multiple supporting sleeves (204), and then the pull rod (305) is pulled outward to make the two movable square tubes (103) move toward each other, and then the two protection parts (2) are pulled to rotate toward the fixing part (1), thereby greatly reducing the space occupied by the equipment and facilitating storage and transportation.

2. The construction method of the building edge structure column construction protection frame according to claim 1 is characterized by: The lower surfaces at both ends of the first fixing bar (101) and the lower surface of one end of the second fixing bar (201) are respectively equipped with a first universal wheel (105) and a second universal wheel (205).
