[0017] The drawings of this specification are schematic diagrams, which assist in explaining the concept of the utility model and schematically show the shapes of various parts and their mutual relationships. Please note that in order to clearly show the structure of various components of the embodiments of the utility model, the drawings are not drawn according to the same scale. The same reference numerals are used to represent the same parts.

[0018] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The embodiments are only used to explain the present invention and are not intended to limit the scope of the present invention. Figure 1 , the preferred embodiments of the utility model are further described in detail:

[0019] like Figure 1 As shown, the utility model is preferably a construction work platform for a confined space of a fertilizer trough, comprising a support bracket 1 and a platform plate 5, wherein one end of the support bracket 1 is fixed on a retaining structure 3, and the other end extends into the fertilizer trough 2 between the retaining structure 3 and the structural outer wall 4 to form a cantilevered section, and the support bracket 1 is provided with a plurality of groups, and the plurality of groups of support brackets 1 are arranged on the retaining structure 3 at intervals along the extension direction of the fertilizer trough 2, and the platform plate 5 is laid and fixed on the cantilevered section of the support bracket 1, and the platform plate 5 blocks and closes the gap between two adjacent groups of support brackets 1, and forms a platform for construction workers to work at the positions where the plurality of groups of support brackets 1 are arranged;

[0020] Since the space of the fertilizer trough 2 is relatively small, the design of the support bracket 1 needs to fully consider the deadweight of the structure, the structural strength and the convenience of installation and disassembly. After fully considering the above factors, the present application selects an angle steel tripod as the support bracket 1. Specifically, the support bracket 1 includes a bracket upright 101, a bracket cross bar 102 and a bracket diagonal bar 103 made of angle steel. The bracket upright 101 is attached to the vertical surface of the enclosure structure 3 close to the fertilizer trough 2 and is anchored to the enclosure structure 3 through a plurality of expansion bolts 105. One end of the bracket cross bar 102 is fixed to the bracket upright 101, and the other end extends into the fertilizer trough 2 to be arranged in a cantilevered state. The bracket diagonal bar 103 is arranged in an inclined state below the bracket cross bar 102, and its two ends are respectively fixed to the bracket cross bar 102 and the bracket upright 101, and the bracket uprights 101, bracket cross bars 102 and bracket diagonal bars 103 form a stable triangular frame structure. In order to further improve the flexibility of the support bracket 1 and facilitate on-site construction, the bracket uprights 101, bracket cross bars 102 and bracket diagonal bars 103 are all fixedly connected in a detachable manner by connecting bolts 104. The single-piece bracket uprights 101, bracket cross bars 102 and bracket diagonal bars 103 can be more conveniently carried and installed in the fertilizer tank 2, reducing the difficulty of installation. After being carried into place, the bracket uprights 101, bracket cross bars 102 and bracket diagonal bars 103 are first assembled into shape by connecting bolts 104, and then the whole is lifted to the designed height for installation, thereby effectively improving the installation efficiency of the support bracket 1;

[0021] In order to ensure the safety of construction workers on the working platform, a safety rope hanging point needs to be provided. For this purpose, the top of the bracket upright 101 is set to exceed the bracket cross bar 102, and a rope threading hole 106 is opened at the top of the bracket upright 101. The safety rope passes through the rope threading holes 106 at the top of each bracket upright 101 in sequence, and the rope ends of the safety rope are bent and fixed by rope clips to prevent it from falling off the bracket upright 101.

[0022] The platform board 5 is a scaffolding board commonly used on construction sites. The platform board 5 is set on the bracket cross bar 102 and fixed by a U-shaped clamp 6. The U-shaped clamp 6 is sleeved on the platform board 5 with its opening facing downward. Its clamp arm passes through the bracket cross bar 102 and is locked on the bracket cross bar 102 by matching nuts. In order to prevent the scaffolding board from having problems with probe boards or slipping, a steel plate is welded to the cantilevered end of the bracket cross bar 102 as a limit baffle 107 to prevent the platform board 5 from slipping out. The bottom end of the limit baffle 107 is fixed on the bracket cross bar 102, and the top end extends upward and exceeds the top surface of the bracket cross bar 102.

[0023] During actual installation, the bracket upright rod 101, the bracket cross rod 102 and the bracket diagonal rod 103 are first assembled by connecting bolts 104;

[0024] After the support bracket 1 is assembled, the construction height is determined in the fertilizer tank 2 and the positioning is marked, and then the assembled support bracket 1 is lifted to the marked position and anchored to the retaining pile or retaining wall through the expansion bolt 105;

[0025] After that, the quality inspection of the support bracket 1 is carried out. After the inspection is completed, the platform board 5 in the form of a scaffolding board is fully laid in double rows. After the scaffolding board is laid, the scaffolding board is pressed and fixed on the bracket cross bar 102 using a U-shaped clamp 6 to prevent the scaffolding board from moving or the occurrence of a probe board situation;

[0026] Next, a steel wire rope is passed through the rope hole 106 at the top of each bracket upright 101 as a safety rope, and the end of the steel wire rope is bent and fixed by a rope clamp to prevent the steel wire rope from falling off;

[0027] Finally, a pre-use inspection is carried out. After passing the inspection, the construction workers wear safety protection equipment and buckle the safety belts on the wire rope before they can carry out construction work. Two sets of safety belt buckles need to be set to ensure that at least one set of buckles is securely connected to the safety rope when the safety belt crosses the bracket upright 101. This application is mainly used for the steel bar binding, formwork support and subsequent waterproofing operations of the inner structure exterior wall 4 of the fertilizer trough 2, which can effectively improve the construction efficiency.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
