Description

Technical Field

[0001] This utility model relates to the field of municipal road construction equipment, specifically to a street light foundation pile casting mold for municipal road construction. Background Technology

[0002] In the construction of municipal roads, the installation of streetlights is crucial, and the quality of the streetlight foundation piles, as the basic structure supporting the streetlights, directly affects the stability and safety of the streetlights. Traditional streetlight foundation pile casting molds are often simple in structure, presenting many inconveniences. Most molds are integral rigid structures, making disassembly difficult. Demolding after casting is time-consuming and laborious, and can easily damage the finished foundation piles. Moreover, the molds have poor adaptability to foundation piles of different specifications. If the design parameters of the streetlight foundation piles change, the entire set of molds must be replaced, increasing construction costs and the risk of project delays. Furthermore, the vibration operation during casting is restricted, making it difficult to ensure uniform and dense concrete, which can easily lead to quality defects such as voids and honeycombing inside the foundation piles, affecting their load-bearing capacity. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a street light foundation pile casting mold for municipal road construction, which realizes convenient demolding, multi-specification adaptation and efficient vibration, thereby improving the efficiency and quality of street light foundation pile casting construction.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a street light foundation pile casting mold for municipal road construction, comprising an outer mold assembly, an inner mold assembly, and a vibration auxiliary mechanism. The outer mold assembly is formed by splicing at least two arc-shaped plates into a circle, with adjacent arc-shaped plates connected by hinges. The bottom of the arc-shaped plates is connected to an outwardly extending base plate, and the base plate has several mounting holes for fixing to the ground.

[0005] The inner mold assembly includes at least two arc-shaped support plates, which are spliced ​​together to form a circle. The at least two arc-shaped support plates are joined by mortise and tenon joints. The arc-shaped support plates are evenly distributed with reverse threaded holes along the circumference. The central column is a hollow tubular structure. The central column is evenly distributed with forward threaded holes along the circumference on its tube wall. One end of the support rod has a screw adapted to the forward threaded hole of the central column, and the other end has a screw adapted to the reverse threaded hole of the arc-shaped support plate. The two ends of the support rod are respectively screwed to the reverse threaded hole of the arc-shaped support plate and the forward threaded hole of the central column. Each arc-shaped support plate is connected to the central column by at least three support rods. A base is provided at the lower end of the central column.

[0006] The vibration auxiliary mechanism is located in the annular cavity between the outer mold assembly and the inner mold assembly. The vibration auxiliary mechanism includes multiple vibration plates evenly distributed along the circumference. A vibration motor is fixedly connected to one side of each vibration plate. The vibration plate is connected to the arc-shaped plate and arc-shaped support plate of the outer mold assembly through an elastic connector.

[0007] Furthermore, the outer side of the arc-shaped plate is evenly distributed with several reinforcing strips along the longitudinal direction. The two ends of the reinforcing strips are provided with bolt holes, which are used to securely connect the arc-shaped plate with fastening bolts. Sealing grooves are provided on the left and right sides of the arc-shaped plate, and sealing strips are provided in the sealing grooves.

[0008] Furthermore, the elastic connector is composed of an elastic connecting block and a connecting strip; the elastic connecting block is located on the inner side of the arc plate and the outer side of the arc support plate of the outer mold assembly, and a slot is opened on the side of the elastic connecting block facing the vibrating plate. A rubber strip is provided in the slot, and one end of the connecting strip is fixedly set on the vibrating plate, while the other end is located in the slot of the elastic connecting block.

[0009] Working principle: During the construction preparation stage, based on the design specifications of the street light foundation piles, select the specifications of the arc plate and arc support plate of the outer formwork component, and screw the support rod so that its screw can be screwed in or out of the threaded hole of the central column to connect and fix the arc support plate; then assemble the outer formwork component, unfold the arc plate into a circle through the hinge, and tighten the fastening bolts on the reinforcing strip; fix the mold to the construction site of the street light foundation pile through the mounting holes of the base plate with expansion bolts.

[0010] During pouring, concrete is poured into the annular cavity between the outer and inner molds. The vibration motor of the vibration auxiliary mechanism is turned on, and the vibration is evenly transmitted to all parts of the concrete through the vibration plate and elastic connectors, expelling air bubbles and making the concrete dense. The elastic connectors buffer the vibration of the vibration plate to avoid damaging the mold structure.

[0011] After the concrete has been poured and initially set, the outer formwork arc plate is removed; the support rod is turned to separate the support rod from the arc plate, the arc plate is retracted, and demolding is easily completed to obtain the formed street light foundation pile.

[0012] The beneficial effects of this utility model are: the spliced ​​outer mold and adjustable inner mold greatly improve the versatility of the mold, one set of molds can be adapted to various specifications of street light foundation piles, saving costs; the convenient demolding method reduces the difficulty of demolding and reduces the probability of foundation pile damage; the built-in vibration auxiliary mechanism optimizes the vibration process, ensures the quality of concrete pouring, improves the structural stability of street light foundation piles, and meets the requirements of efficient and high-quality construction of municipal roads; the parts not described in detail in this utility model are existing commonly used technologies.
