Description

Technical Field

[0001] The invention relates to the technical field of high-altitude work protection devices, and in particular to a high-altitude cap beam construction safety protection device. Background Art

[0002] In bridge design, columnar piers are a commonly used structural type. The cap beam refers to the crossbeam installed on the top of the pier to support, distribute and transfer the load of the superstructure. The cap beam is an important component that connects the upper and lower parts. When the cap beam supports the upper bridge plate components, it needs to bear concentrated stress, so pad stones will be installed at the connection.

[0003] Currently, when constructing bridge slab components, manual labor is required to perform a series of construction operations on the cap beam. However, the working environment is high-altitude work, and there are safety hazards when constructing on the exposed cap beam. Construction safety requires wearing a safety rope, but the cap beam has a simple structure and there is no location to install a safety rope. The method of installing guardrails around the cap beam is inefficient, and it is inconvenient to disassemble and assemble the guardrails at high altitude. Therefore, it is considered to design a safety protection device that can be quickly disassembled and assembled to ensure the safety of construction operations on the cap beam. In view of this, we propose a safety protection device for high-altitude cap beam construction. Summary of the invention

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0033] See also Figure 1-7 The present invention describes the above technical solution in detail through the following embodiments:

[0034] A high altitude cap beam construction safety protection device, such as Figure 1 , Figure 2 In the structure shown, a cap beam 2 is built between the piers 1. In order to bear the prefabricated components above, the cap beam 2 is currently provided with a plurality of evenly arranged pad stones 3 above; specifically, it includes:

[0035] Two fixing components 5, such as Figure 1 and Figure 2 The installation relationship shown is used for clamping and installing on the pad stone 3 at both ends of the cap beam 2, so as to obtain a stable clamping and fixing state; it includes a clamping block 51 inserted and clamped on the pad stone 3, and a mouth-shaped sleeve block 53 sleeved on the pad stone 3 and located below the clamping block 51, and side limit units 54 are detachably installed on both sides of the clamping block 51; in this embodiment, a safety steel cable 4 is installed between the two fixing components 5. When in use, the safety steel cable 4 is used to provide a hanging position for the safety rope carried by the operator. The safety rope on the operator is hung on the safety steel cable 4, which does not affect their construction work while ensuring their safety and anti-falling performance.

[0036] Specifically, Figure 3-Figure 7 As shown in the structure, the clamp block 51 of the present application adopts an inverted U-shaped structure with an opening facing downward; the side limit unit 54 includes a clamp head 541 installed with a fastening bolt 542. The clamp head 541 of this embodiment adopts a horizontal U-shaped structure with an opening toward the open side of the clamp block 51. The clamp head 541 is installed on the open sides of both ends of the clamp block 51 by fastening bolts 542. By tightening the fastening bolts 542, the structure as a whole can be kept against the cushion stone 3. However, relying solely on the force of the fastening bolts 542 is not safe in the event of an accidental fall, and the device may be completely peeled off the cushion stone 3.

[0037] In order to avoid the situation that the device may peel off the cushion stone 3 when the force is large, the present embodiment Figure 6 and Figure 7 In the structure shown in FIG. 1 , a second L-shaped block 544 is provided on the clamp block 51, and first L-shaped blocks 531 corresponding to the positions of the second L-shaped block 544 are provided on both sides of the mouth-shaped sleeve block 53; Figure 7 As shown in the clamping relationship, the first L-shaped clamping block 531 is provided with a clamping slot with an opening facing downward, and the second L-shaped clamping block 544 is provided with a clamping slot clamped with the first L-shaped clamping block 531 and with an opening facing upward, the two are clamped with each other, and in this example, the bottom surface of the second L-shaped clamping block 544 is in horizontal contact with the cap beam 2. When a fall occurs, the clamped first L-shaped clamping block 531 and the second L-shaped clamping block 544, based on the condition of being fitted on the cap beam 2, will maintain a clamping force between the device and the cap beam 2 and the cushion stone 3, that is, the pulling force of the falling object is converted into a clamping force of the device, thereby preventing the device from sliding and peeling off the cushion stone 3.

[0038] It should be noted that in this embodiment, an L-shaped bracket 543 is fixedly connected to the outside of the clamp head 541, and a support bracket 5431 is provided on the L-shaped bracket 543. Figure 1 and Figure 2 The L-shaped bracket 543 is installed at the corner of the cap beam 2 and fits on the surface of the cap beam 2. As a whole, the cap beam 2 structure further obtains a force that resists the falling path, thereby keeping the device in a "locked" and stable state. Even if a fall occurs in time, the safety cable 4 will keep the device in a suspended state, providing a buffer time for rescue. The device has a multiple force tightening effect, which is conducive to effective installation without damaging the cap beam 2. The device has a simple structure and is suitable for scenes where high-altitude operations are inconvenient.

[0039] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0040] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the attached claims rather than the above description, and it is intended that all changes that fall within the meaning and scope of the equivalent elements of the claims are included in the present invention.
