Description

Technical Field

[0001] The present application relates to the technical field of safety frames, and in particular to a construction safety frame for civil engineering buildings and a construction method thereof. Background Art

[0002] A safety rack is a work platform erected during civil construction to ensure the safety of construction workers, stack materials, and transport them over short distances. It plays an important role in the construction process and provides a strong guarantee for safe construction. Safety racks are divided into two types: cantilever and pull-up types, depending on their installation and splicing methods.

[0003] Compared with the cantilever safety frame, the pull-up safety frame significantly reduces the amount of I-beams used during installation and splicing, and reduces the weight of the safety frame itself. It has a higher safety factor and effectively shortens the construction period during installation and splicing, becoming the first choice for safety frame installation and splicing in modern building construction. However, when the existing pull-up safety frame uses fasteners to install and splice I-beams, due to the large mass and size of the I-beams, the operator's body position is required to be high when disassembling and assembling it in the air on a high-rise wall. The disassembly and assembly of the I-beams is difficult and there are major safety hazards.

[0004] Therefore, there is an urgent need for a safety frame structure for civil engineering construction to solve the defects of the above-mentioned existing safety frames in actual use. Summary of the Invention

[0005] The present application proposes a construction safety frame for civil engineering buildings and a construction method thereof, which has the advantages of effectively reducing the difficulty of operating the I-beams when they are suspended and disassembled, and having high safety and reliability. It is used to solve the problem that in the process of installing and splicing the I-beams using fasteners on the existing pull-up safety frame, due to the large mass and size of the I-beams, the operator's body position is required to be high when suspended and disassembled on high-rise walls, the disassembly and assembly of the I-beams is difficult, and there are major safety hazards.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical solution: a construction safety frame for civil engineering construction, comprising a wall on which a safety frame needs to be installed for construction, an upper ear seat being fixedly installed on the top of the front face of the wall by fasteners, a lower support seat being fixedly installed on the bottom of the front face of the wall and located directly below the upper ear seat by fasteners, an I-beam being clamped on the end of the lower support seat, a pull rod being pinned on one side of the top end of the I-beam, and the other end of the pull rod being pinned to the upper ear seat, so that the end of the I-beam can be tightened by the upper ear seat and the pull rod and stably fixed to the wall, and a plurality of groups of upper ear seats, lower support seats and I-beams are arranged at equal intervals on the wall, and a cross bar is arranged between two groups of I-beams to form a working platform;

[0007] The top of one side of the end face of the lower support seat is provided with a card slot, and the middle part of one side of the end face of the lower support seat is fixedly installed with an L-shaped block for supporting the end of the I-beam, and a threaded hole is provided at the end of the L-shaped block. Compared with the I-beam, the lower support seat is lighter in weight and smaller in size, which is convenient for installation and disassembly, and then the lower support seat is used to clamp the I-beam, which effectively reduces the difficulty of disassembling the I-beam directly through fasteners. The left end of the I-beam is fixedly installed with a card block that cooperates with the card slot, and then the card block and the card slot can be used to fix the I-beam. They cooperate with each other to clamp the I-beam, and a second positioning block is fixedly installed in the middle of the bottom end of the I-beam, and a linkage screw that cooperates with the threaded hole is movably sleeved inside the second positioning block. When installing the I-beam, first place the left side of the bottom end of the I-beam on the L-shaped block, and then screw the linkage screw to form a threaded engagement with the threaded hole, and drive the I-beam to move along the direction of the lower support seat until the clamping block on it is completely clamped in the clamping groove to fix one end of the I-beam, and then fix one side of the top end of the I-beam to the upper ear seat through the pull rod.

[0008] Furthermore, a first positioning block is fixedly installed on the left side of the bottom end of the I-beam with a spacing the same as the width of the top end of the L-shaped block. Therefore, in the process of clamping the end of the I-beam onto the L-shaped block, the first positioning block can be used to align the end of the I-beam with the L-shaped block, and in the process of suspending and moving the I-beam, the I-beam is less likely to shake left and right.

[0009] Furthermore, a positioning groove is provided at the right end of the L-shaped block, and a protrusion matching the same is provided at the inner end of the second positioning block. Then, through the arrangement of the positioning groove and the protrusion on the second positioning block, when the blocking block is fully engaged in the blocking groove, the movement of the I-beam is further restricted, and the firmness of the lower support seat when engaging the I-beam is improved, thereby alleviating the load pressure borne by the blocking block and the blocking groove.

[0010] Furthermore, the distance between the right end face of the first positioning block and the end face of the clamping block is smaller than the distance between the inner end of the L-shaped block and the right end face of the lower support seat, thereby ensuring that during the process of disassembling and assembling the I-beam, the left end of the I-beam can be stably placed on the L-shaped block, and under the threaded transmission action of the linkage screw, the I-beam can be forced to move left and right along the trajectory of the L-shaped block.

[0011] Furthermore, the clamping slot is configured as a rectangular hole structure, and the overlapping depth between the clamping slot and the clamping block is designed according to the load-bearing capacity of the I-beam.

[0012] A construction method for a construction safety frame for civil engineering construction includes the following construction process:

[0013] S1. Fix the upper ear base and the lower support base to specific positions of the wall where the safety frame needs to be installed for construction by fasteners;

[0014] S2. Then, suspend the I-beam just above the L-shaped block on the lower support seat, and place one end of the I-beam on the L-shaped block so that it is horizontal. Then, use a tool to rotate the linkage screw to engage the threaded hole and force the I-beam to move toward the lower support seat until the clamping block is completely engaged with the clamping slot;

[0015] S3. Use a tie rod to fix one side of the top of the I-beam to the upper ear seat, and tighten the tie rod to form an effective support for one end of the I-beam;

[0016] S4. Afterwards, according to the requirements of the construction, a number of upper ear seats and I-beams arranged at equal intervals are set on the wall, and cross bars are laid on the I-beams arranged at equal intervals to form a working platform on the wall.

[0017] The beneficial effects of the present invention are as follows:

[0018] The present application provides a construction safety frame for civil engineering buildings and a construction method thereof. Regarding the arrangement of the lower support seat, the I-beam and the connection structure therebetween, the lower support seat is lighter in weight and smaller in size than the I-beam, making it easier to install and disassemble. The I-beam is then clamped with the lower support seat, thereby solving the problem of the existing pull-up safety frame posing a greater safety hazard during the process of installing and splicing the I-beam using fasteners due to the large weight and size of the I-beam during the process of disassembling the I-beam due to its large weight and size, and effectively reducing the operational difficulty of directly disassembling the I-beam using fasteners.
