Description

Technical Field

[0001] The utility model belongs to the field of building construction safety, and particularly relates to a concrete support beam guardrail installation device. Background Art

[0002] The function of the concrete support beam is to support and share the load of the structure. When carrying out related construction work, workers need to walk on the concrete support beam. In order to prevent the hidden danger of falling from height and ensure the safety of workers and surrounding personnel, it is necessary to install a guardrail on the concrete support beam. When installing the guardrail, it is necessary to drill holes on the concrete support beam to fix the vertical poles of the guardrail, and then install the yellow protective mesh on the vertical poles. Because there are many steel bars in the concrete support beam, it is difficult to drill holes in the concrete support beam, the operation process is unsafe, the workload is large, and drilling will also damage the concrete support beam structure. In addition, the yellow protective mesh is easily damaged, the protective effect is poor, the turnover rate is low, and the cost is high. Summary of the invention

[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0018] The concrete support beam guardrail installation device of this embodiment includes a plurality of U-shaped steel plates 1, the inner width of the U-shaped steel plate 1 is equal to the width of the concrete support beam 2, and the U-shaped steel plate 1 is opened downward and just stuck on the concrete support beam 2. In order to make the U-shaped steel plate 1 more tightly stuck on the concrete support beam 2, the U-shaped steel plate 1 can be slightly wider at the top and narrower at the bottom, that is, the longitudinal section of the U-shaped steel plate 1 is a trapezoid, and the lower inner width is 2-5cm smaller than the upper inner width. In this way, the side plates of the U-shaped steel plate 1 can have a certain clamping force on the concrete support beam 2, and the side plates of the U-shaped steel plate 1 are more firmly stuck on the concrete support beam 2. Because the U-shaped steel plate 1 is the basis for installing the guardrail later, in order to ensure firmness, the length of the U-shaped steel plate 1 is preferably 30-60cm, and the length here refers to the length along the direction of the concrete support beam 2, and the height of the side plates of the U-shaped steel plate 1 is not less than 50cm.

[0019] Vertical fixed tubes 3 are symmetrically welded on the left and right outer sides of the U-shaped steel plate 1. The upper end of the fixed tube 3 is open and the lower end is closed. The fixed tube 3 is used to insert the vertical rod 4 of the guardrail to be installed later. Since the vertical rod 4 of the guardrail can be a round tube or a rectangular tube, the fixed tube 3 can also be a round tube or a square tube. The size of the fixed tube 3 is consistent with the size of the vertical rod 4 of the guardrail to ensure that the vertical rod 4 can just be inserted into the fixed tube 3. In order to ensure the stability of the guardrail, it is preferred that the height of the fixed tube 3 is not less than 50 cm.

[0020] A lifting plate 5 is welded on the left and right outer sides of the U-shaped steel plate 1. The lifting plate 5 is provided with a lifting hole 6. The U-shaped steel plate 1 is lifted by the lifting plate 5 and placed at a suitable position of the concrete support beam 2. In order to ensure stability during lifting, it is preferred that the lifting plates 5 are distributed in a diagonal form, as shown in the attached figure. Figure 2 As shown, the hanging plates 5 on both sides are staggered and arranged in a diagonal manner.

[0021] In order to further enhance the stability of the entire device, adjacent U-shaped steel plates 1 are connected as a whole through connecting rods 8. Specifically, a plurality of screws 7 are welded on the left and right outer surfaces of the U-shaped steel plate 1. The screws 7 are perpendicular to the U-shaped steel plate 1. Circular holes are provided at both ends of the connecting rods 8. The two ends of the connecting rods 8 are sleeved on the screws 7 of the adjacent U-shaped steel plates 1 through the circular holes, and then the connecting rods 8 and the screws 7 are fixed together by nuts 9. In this embodiment, a screw 7 is welded on the upper and lower sides of one side of the outer side of the U-shaped steel plate 1, and two screws 7 are welded on the upper part of the other side. A horizontal connecting rod 8 and an inclined connecting rod 8 are respectively fixed between the same sides of the adjacent U-shaped steel plates 1. A triangle is formed between the two connecting rods 8. The connecting rod 8 connects the two adjacent U-shaped steel plates 1 as a whole.

[0022] Usage process: First, hoist the U-shaped steel plate 1 onto the concrete support beam 2 through the hoisting rope and the hoisting plate 5, then press the U-shaped steel plate 1 downward to make it tightly clamped on the concrete support beam 2, and clamp a U-shaped steel plate 1 on the concrete support beam 2 at a certain interval. After all the U-shaped steel plates 1 are installed, put the two ends of the connecting rod 8 on the screw rod 7 of the adjacent U-shaped steel plates 1 respectively, and fix the connecting rod 8 on the screw rod 7 through the nut 9 to connect the adjacent U-shaped steel plates 1 as a whole. Then insert the vertical rod 4 of the guardrail into the fixed tubes 3 on both sides, and then fix the crossbar 10 of the guardrail on the vertical rod 4 through the fasteners to form the guardrail, and the installation is complete. When disassembling, you only need to separate the crossbar 10 and the vertical rod 4, pull out the vertical rod 4, and then lift the U-shaped steel plate 1 upward from the concrete support beam 2. The device can be used repeatedly.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
