Description

Technical Field

[0001] This utility model relates to the field of light pole base construction, and in particular to a prefabricated light pole base. Background Technology

[0002] Existing pole light bases mostly utilize cast-in-place concrete structures, requiring formwork erection, rebar tying, concrete pouring, and curing. The curing phase typically takes several weeks, severely hindering construction progress, especially in projects with tight schedules. Furthermore, cast-in-place structures necessitate transporting large quantities of bulk building materials, resulting in low vehicle capacity and inefficient transportation. Currently, large pole light foundations often employ cast-in-place construction techniques, leading to low construction efficiency and difficulty in guaranteeing quality. Using prefabricated assembly methods, with their heavy lifting capacity, places high demands on equipment.

[0003] Cast-in-place concrete construction involves excavating the foundation pit, tying the reinforcing cage, erecting the formwork, pouring concrete, and curing to form an integral foundation structure. This process requires a long time to occupy the construction site, and the concrete curing period is as long as 28 days, which seriously restricts the progress of the project. The construction period for a single cast-in-place foundation is about 15-20 days, of which the erection and dismantling of the formwork accounts for more than 40% of the working time.

[0004] In addition, cast-in-place construction is greatly affected by environmental factors, the quality of concrete is prone to fluctuation, and the amount of on-site work is large, resulting in high labor costs. To solve the above problems, it is necessary to develop a prefabricated pole light base that uses high-strength concrete and can be assembled on-site. Utility Model Content

[0005] The main purpose of this utility model is to provide a prefabricated light pole base, which solves the problem of long construction cycle for light pole bases constructed with cast-in-place concrete.

[0014] The upper reinforcing bar holes are arranged in the upper pressure plate groove, and the lower reinforcing bar holes are arranged in the lower pressure plate groove;

[0045] The upper pressure plate groove 103 and the lower pressure plate groove 105 are used to install the tensioning plate 201.

[0046] In the preferred embodiment, the reinforcing bar assembly 2 includes multiple U-shaped insert reinforcing bars 202, which are arranged in the upper reinforcing bar hole 104 and the lower reinforcing bar hole 106.

[0047] The upper reinforcing bar holes 104 and the lower reinforcing bar holes 106 are arranged alternately in the base block 101.

[0048] In the preferred embodiment, a threaded portion 203 is provided on one side of the lead of the inserting steel bar 202, and a tensioning plate 201 is provided between the inserting steel bar 202 and the base assembly 1.

[0052] Example 2

[0053] In conjunction with Embodiment 1, the detailed construction process of a prefabricated pole light base is as follows: First, preparatory work is carried out before construction. The column assembly 3 and the multi-layer base assembly 1 are transported together to the construction site. During transportation, the prefabricated column 301, base blocks 101, etc. can be loaded separately to make full use of the transportation space.

[0054] Upon arrival at the construction site, the assembly of the light pole bases began in the prefabrication yard. First, the corresponding prefabricated columns 301 were selected and assembled into column components 3 according to the design requirements. This ensured that the distribution of the assembled connecting columns 302 was completely matched with the hole positions on the base plate 501 of the light holder, laying the foundation for subsequent installation.

[0055] Next, using the tension rod 401 in the tensioning assembly 4, it is passed through the upper connecting hole 303 and the lower connecting hole 304 below the column assembly 3, and also through the tensioning hole 305 on the upper side and the tensioning hole 306 on the lower side of the column assembly 3, so that the tension rod 401 completely penetrates multiple precast columns 301. Then, nuts are installed on the threads at both ends of the tension rod 401, and the multiple precast columns 301 are tightened by tightening the nuts, so that the column assembly 3 forms a stable whole.

[0056] After the column assembly 3 is assembled, base blocks 101 are placed around the column assembly 3. Since there are four base blocks 101, the mating grooves 102 of these four base blocks 101 need to be combined together towards the center so that the mating grooves 102 fit against the outside of the column assembly 3 and together form a fixing groove 107, so that the column assembly 3 is stably placed in the fixing groove 107.

[0057] Subsequently, the tensioning plate 201 is placed in the upper pressure plate groove 103 and lower pressure plate groove 105 on one side of the base block 101. The upper pressure plate groove 103 and lower pressure plate groove 105 are arranged on the side away from the mating groove 102. At the same time, it is ensured that the upper connecting hole 303 corresponds one-to-one with the upper reinforcing bar hole 104 and is arranged coaxially, and the lower connecting hole 304 corresponds one-to-one with the lower reinforcing bar hole 106 and is arranged coaxially. The upper reinforcing bar hole 104 is arranged in the upper pressure plate groove 103, and the lower reinforcing bar hole 106 is arranged in the lower pressure plate groove 105.

[0058] Next, multiple U-shaped insert steel bars 202 from the steel bar assembly 2 are arranged in the upper steel bar hole 104 and the lower steel bar hole 106, with the upper steel bar hole 104 and the lower steel bar hole 106 arranged alternately in the base block 101. The insert steel bars 202 pass through the upper steel bar hole 104 and the lower steel bar hole 106, with the threaded part 203 on one side of its lead exposed. Nuts are installed using the threaded part 203 to lock the insert steel bars 202 to the tension plate 201, thereby completing the fixed connection between the base assembly 1 and the column assembly 3.

[0059] Next, the foundation pit 6 was excavated according to the design dimensions. The bottom of the foundation pit 6 was leveled and compacted to ensure the stability of the foundation. Then, the assembled light pole base was hoisted into the foundation pit 6 using a crane. The top level of the column assembly 3 was adjusted using professional equipment to meet the construction standards.

[0060] Finally, step S8 is executed to backfill the foundation pit 6. Suitable backfill materials are selected, and the backfill is carried out in layers and the ground is compacted to ensure that the light pole base is stable. The construction of the entire light pole base is completed. No concrete needs to be poured in place. Subsequently, the light pole can be connected to the base plate 501 of the light holder under the high light pole 5 through the connecting column 302 at the top of the precast column 301 to complete the installation of the high light pole.
