Description

Technical Field

[0001] This utility model relates to a working platform, specifically a protective platform for bridge construction. Background Technology

[0002] In road and bridge engineering, a cap beam refers to a horizontal beam installed on top of a pier to support, distribute, and transfer the load of the superstructure. During the construction of cap beams, safety protection platforms are typically installed on the piers to protect the safety of workers.

[0003] Protective platforms are usually welded from channel steel. This type of fully welded protective platform has high strength. The disadvantage is that because different cap beams have different sizes, protective platforms of corresponding sizes need to be prepared, which increases the cost.

[0004] To address this issue, adjustable-width protective platforms have been designed in this field. For example, Chinese patent document CN219753019 U (application number 202321157495.X) discloses an adjustable-width protective device for a support pad construction cap beam, comprising two symmetrical side guardrail assemblies. A stop bar is fixedly installed at the bottom of each side guardrail assembly, and a baffle is fixedly installed on one side of the stop bar. A connecting crossbar is vertically fixedly installed in the middle of one side of each side guardrail assembly. An adjusting connecting pipe is slidably fitted onto the connecting crossbar, and a locking mechanism is provided on the adjusting connecting pipe for locking or releasing it from the connecting crossbar. A telescopic upper pull rod is provided between the tops of the two side guardrail assemblies, and the end of the telescopic upper pull rod is detachably and fixedly connected to the end of the side guardrail assembly. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a protective platform for the construction of cap beams with high structural strength and adjustable width.

[0006] The technical solution for achieving the purpose of this utility model is a protective platform for the construction of a cap beam, including a frame, crossbars, sleeves, connectors, a protective net, and a walkway. The frame includes a left frame and a right frame, and the crossbars connect the left frame and the right frame. The sleeves are fitted onto the crossbars located outside the left and right frames, and the ends of the sleeves are connected to the connectors. The connectors are provided with upward-facing slots, and the protective net is inserted into the connectors. The walkway is placed above the sleeves.

[0007] The crossbar includes two end crossbars, one at the front and one at the back. The end crossbars have first mounting holes at equal intervals and are fixed to the frame with bolts.

[0008] The sleeve is provided with second mounting holes at equal intervals, and bolts are used to fix the sleeve to the crossbar.

[0009] The frame includes two vertical bars, an upper and a lower one, and a vertical post between the two vertical bars. A protrusion is provided below the upper vertical bar, and a limiting part for placing a horizontal bar is formed between the upper vertical bar and the protrusion. A connecting hole is opened on the vertical post corresponding to the limiting part.

[0010] The number of sleeves is the same as the number of crossbars, and each sleeve is fitted onto the corresponding crossbar.

[0011] For the sleeve on the right, when the sleeve moves to the right, the overlap between the sleeve and the crossbar decreases, the width of the support formed becomes wider, and the walkway panel can be placed further away from the frame; when the sleeve moves to the left, the overlap between the sleeve and the crossbar increases, the width of the support formed becomes narrower, and the walkway panel is placed closer to the frame.

[0012] For the sleeve on the left, when the sleeve moves to the left, the overlap between the sleeve and the crossbar decreases, the width of the support formed becomes wider, and the walkway panel can be placed further away from the frame; when the sleeve moves to the right, the overlap between the sleeve and the crossbar increases, the width of the support formed becomes narrower, and the walkway panel is placed closer to the frame.

[0013] The crossbar also includes a middle crossbar, which is placed away from the pier column.

[0014] This utility model has positive effects:

[0015] The adjustable width of the protective platform of this utility model includes two aspects. First, the width between the left and right frames is adjustable, so the protective platform of this utility model can be applied to cap beam piles with similar dimensions within a certain range. Second, the width of the supports on the outer sides of the left and right frames is adjustable. By pulling the sleeve outward or pushing it inward from the crossbar, the width of the supports can be adjusted, thereby adjusting the placement position of the walkway board, so that workers of different trades can obtain the most appropriate working distance from the cap beam.

[0016] The protective platform of this utility model allows for easy adjustment of the width of the supports on the outer sides of the left and right frames. Several sleeves are connected to the connectors of the protective net. By pushing and pulling the connectors, the position of the sleeves on the crossbars can be adjusted to obtain supports of different widths. Attached Figure Description

Therefore, they should not be construed as limitations on the embodiments of this application.

[0023] (Example 1)

[0024] In the following description, according to Figure 1 The directions are defined as follows: left and right are called horizontal, and front and back are called vertical.

[0025] See Figures 1 to 3 The protective platform for the construction of the cap beam in this embodiment includes a frame 1, a crossbar, a sleeve 4, a connector 5, a protective net 6, and a walkway 7. The frame 1 includes a left frame 1a and a right frame 1b, and the crossbar connects the left frame 1a and the right frame 1b. The sleeve 4 is fitted onto the crossbar located outside the left frame 1a and the right frame 1b, and the end of the sleeve 4 is connected to the connector 5. The connector 5 is provided with an upward-facing slot, and the protective net 6 is inserted into the connector 5. The walkway 7 is placed above the sleeve 4.

[0026] The frame 1 includes two upper and lower longitudinal bars 1-1 and uprights between the two longitudinal bars 1-1. The uprights include at least two at the front and rear ends, and the number of uprights in the middle is determined according to the length of the longitudinal bars 1-1; the longer the length, the more uprights are required. To further increase strength, reinforcing bars (not shown in the figure) can also be installed between the longitudinal bars 1-1 and between the uprights.

[0027] A protrusion 1-2 is provided below the upper vertical bar 1-1, thereby forming a limiting part between the upper vertical bar 1-1 and the protrusion 1-2 for placing the horizontal bar. A connecting hole is opened on the column corresponding to the limiting part.

[0028] The crossbar includes two end crossbars 2 at the front and rear and a middle crossbar 3, with the middle crossbar 3 placed away from the pier column.

[0029] The end crossbar 2 is placed within the limiting part formed between the upper longitudinal bar 1-1 and the protrusion 1-2 of the frame 1. The end crossbar 2 has first mounting holes 2-1 at equal intervals, and the end crossbar 2 is fixed to the frame 1 by bolts.

[0030] After the distance between the left frame 1a and the right frame 1b is determined, the end crossbar 2 and the middle crossbar 3 are fixed to the uprights of the frame using bolts. If it is necessary to adjust the distance between the left frame 1a and the right frame 1b, the crossbars can be disassembled for adjustment, and then reconnected with crossbars after adjustment.

[0031] Sleeve 4 is a hollow tube that fits onto both sides of the crossbar, positioned on the left side of the left frame 1a or the right side of the right frame 1b. Second mounting holes 4-1 are evenly spaced on sleeve 4. Sleeve 4 can move left and right on the crossbar.

[0032] The number of sleeves 4 is the same as the number of crossbars, and each sleeve is fitted onto the corresponding crossbar.

[0033] For the right sleeve 4, when the sleeve 4 moves to the right, the overlap between the sleeve 4 and the crossbar decreases, the width of the support formed becomes wider, and the walkway board can be placed further away from the frame; when the sleeve 4 moves to the left, the overlap between the sleeve 4 and the crossbar increases, and the width of the support formed by the sleeve 4 and the crossbar becomes narrower.

[0034] For the sleeve 4 on the left, when the sleeve 4 moves to the left, the overlap between the sleeve 4 and the crossbar decreases, and the width of the support formed becomes wider; when the sleeve 4 moves to the right, the overlap between the sleeve 4 and the crossbar increases, and the width of the support formed by the sleeve 4 and the crossbar becomes narrower.

[0035] After the positions of sleeve 4 and crossbar are determined, sleeve 4 is fixed to crossbar with bolts.

[0036] See Figure 3 The outer ends of all sleeves 4 are connected to the connectors 5; the push-pull connectors 5 can control the movement of all sleeves 4. The connectors 5 have upward-facing slots.

[0037] The protective net 6 is plugged into the connector 5. The protective net can be a whole piece of protective net or a protective net spliced ​​from units.

[0038] The walkway 7 is placed above the sleeve 4 and can be fixed to the sleeve 4 with fasteners.

[0039] The adjustable width of the protective platform of this utility model includes two aspects. First, the width between the left and right frames is adjustable; second, the width of the supports on the outer sides of the left and right frames is adjustable, by pulling the sleeve 4 outwards from the crossbar (e.g., Figure 2 As shown, the crossbar exposes two mounting holes) or pushes it inward (as shown). Figure 1 As shown, the crossbar has no exposed mounting holes. The width of the bracket can be adjusted, thereby adjusting the placement of the walkway slab, so that workers of different trades can obtain the most appropriate working distance from the cap beam.
