Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of street lamp construction, in particular to a street lamp foundation pouring auxiliary device and a construction method. BACKGROUND

[0002] With the continuous development of urban road construction and lighting engineering, street lamps as important public infrastructure, the installation quality is directly related to road traffic safety and urban image. In the construction process of street lamp, the foundation pouring is the key link to ensure the long-term stable service of the lamp pole. At present, the method of pre-burying the cage is generally used to fix the lamp pole in the construction of street lamp foundation, and the verticality of the cage and the accuracy of the exposed length of the bolt have important influence on the subsequent installation quality of the lamp pole.

[0003] However, in the actual construction process, the phenomenon of the cage position deviating after the completion of concrete pouring often occurs. Specifically, the verticality of the cage exceeds the allowable deviation range, or the exposed length of the anchor bolt is insufficient, resulting in that the lamp pole cannot be normally installed. The reason is that, in the process of concrete pouring and vibrating, although the construction personnel will continuously adjust the position of the cage, the cage may still sink or tilt under the action of its own weight in the plastic stage when the concrete has not formed strength. Since it takes several hours from the completion of concrete pouring to the complete loss of plasticity and the beginning of strength, the cage lacks effective positioning measures during this period, and the position is easy to change.

[0004] When the concrete is completely solidified, if the deviation of the position of the cage is found, it is usually difficult to effectively adjust. The construction personnel often can only take temporary measures such as adjusting the installation height of the nut and reducing the number of gaskets to remedy, which may affect the installation firmness of the lamp pole. If the deviation is too large to be compensated by adjustment, the already poured foundation needs to be abandoned and re-constructed, which not only causes material waste, but also affects the progress of the project. SUMMARY

[0005] The present application aims to solve the above problems, and provides a street lamp foundation pouring auxiliary device and a construction method which can effectively maintain the design position of the cage.

[0006] The present application solves the problem by adopting the following technical scheme: A street lamp foundation pouring auxiliary device, comprising two parallel rigid horizontal rods; the bottom of the horizontal rod is provided with a supporting leg, the bottom end of the supporting leg is used for welding and fixing with the flange plate of the street lamp foundation, and the horizontal rod is erected above the foundation pit to form a stable support structure for maintaining the spatial position of the foundation cage before the concrete solidifies.

[0007] A street lamp foundation pouring construction method, comprising the following steps: S1: placing the flange plate of the street lamp foundation at a predetermined position in the foundation pit.

[0008] S2: Weld and fix the bottom end of the support leg of the street light foundation pouring auxiliary device to the flange, so that the crossbar is erected on the ground on both sides of the foundation pit.

[0009] S3: Use a level measuring instrument to adjust the crossbar to a horizontal position.

[0010] S4: Insert the pre-embedded conduit into the center hole of the flange, and at the same time insert the fixing bolts of the foundation cage into the four corner bolt holes of the flange, and use nuts to initially fix them.

[0011] S5: Use a vertical measuring instrument to measure the verticality of the foundation cage. Adjust the height of each nut to adjust and fix the foundation cage in a vertical position.

[0012] S6: Carry out the concrete pouring operation in layers, and vibrate and compact each layer of concrete until the foundation design elevation is reached.

[0013] S7: Use multiple sets of street light foundation pouring auxiliary devices for continuous operation. After the foundation concrete poured first reaches the predetermined strength, remove the auxiliary devices on the foundation and use them for subsequent foundation pouring construction.

[0014] The present invention, which adopts the above technical solution, has the following prominent features compared with the prior art: This invention provides continuous and stable spatial positioning support for the ground cage during the critical stage from the completion of concrete pouring to its complete solidification by setting up a support structure and horizontal crossbar that are welded and fixed to the flange. This helps reduce displacement caused by the ground cage's own weight and provides structural assurance for maintaining the ground cage's designed position. Simultaneously, the coordinated operation of horizontal adjustment and vertical measurement helps improve the positional accuracy of the ground cage installation, creating favorable conditions for subsequent light pole installation. The construction method of using multiple sets of devices in a cyclical manner can improve equipment utilization efficiency while ensuring construction quality.

[0015] As a preferred embodiment, a further technical solution of the present invention is: Furthermore, the crossbars are made of angle steel, a material commonly used in construction engineering. Its cross-sectional properties may provide good bending resistance, which helps maintain the stability of the support system, while also providing a certain degree of durability in the construction environment.

[0016] Furthermore, the support legs are welded vertically to the bottom of the crossbar, which helps to form a stable support system, makes the load transfer path clearer, and enhances the overall stability of the device during the concrete pouring process.

[0017] Furthermore, two support legs are symmetrically arranged at the bottom of each crossbar. The symmetrical arrangement of support points helps to balance the force and distribute the load, which can improve the stability of the device during the support process and reduce the risk of deformation caused by uneven force.

[0018] Furthermore, welding the bottom end of the support leg to the midpoint of the connection line between the pre-drilled hole in the center of the flange and the bolt holes at the four corners can make the distribution of the support force more reasonable, help maintain the flatness of the flange during the concrete pouring process, and provide a reliable reference surface for the positioning of the ground cage.

[0020] The present invention will be further described below with reference to embodiments, the purpose of which is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0021] A street light foundation pouring auxiliary device includes two parallel rigid crossbars 1; the bottom of the crossbars 1 is provided with a support leg 2, the bottom end of the support leg 2 is used to weld and fix to the flange 3 of the street light foundation, and the crossbars 1 are erected above the foundation pit to form a stable support structure for maintaining the spatial position of the foundation cage before the concrete solidifies.

[0022] Furthermore, the crossbar 1 is made of angle steel, with a specification of 2 meters long and 30*30*3 angle steel. This type of material is commonly used in construction engineering. Its cross-sectional characteristics may provide good bending resistance, which helps to maintain the stability of the support system, while also having a certain degree of durability in the construction environment.

[0023] Furthermore, the support leg 2 is vertically welded below the crossbar 1, which helps to form a stable support system, makes the load transfer path clearer, and enhances the overall stability of the device during the concrete pouring process.

[0024] Furthermore, two support legs 2 are symmetrically arranged at the bottom of each crossbar 1. The symmetrical arrangement of support points helps to balance the force and distribute the load, which can improve the stability of the device during the support process and reduce the risk of deformation caused by uneven force.

[0025] A method for pouring concrete for street light foundations includes the following steps: S1: Place the flange 3 of the street light foundation in the predetermined position in the foundation pit.

[0026] S2: Weld and fix the bottom end of the support leg 2 of the street light foundation pouring auxiliary device to the flange 3 so that the crossbar 1 is erected on the ground on both sides of the foundation pit.

[0027] S3: Use a level measuring instrument to adjust the horizontal bar 1 to a horizontal state.

[0028] S4: Insert the pre-embedded conduit into the center reserved hole of flange 3, and at the same time insert the fixing bolts of the foundation cage into the four corner bolt holes of flange 3, and use nuts to initially fix them.

[0029] S5: Use a vertical measuring instrument to measure the verticality of the foundation cage. Adjust the height of each nut to adjust and fix the foundation cage in a vertical position.

[0030] S6: Carry out the concrete pouring operation in layers, and vibrate and compact each layer of concrete until the foundation design elevation is reached.

[0031] S7: Use multiple sets of auxiliary devices for street light foundation pouring to carry out continuous operation. After the foundation concrete poured first reaches the predetermined strength, remove the auxiliary devices on the foundation and use them for subsequent foundation pouring construction. It generally takes about 5 hours for the concrete to completely lose its plasticity and begin to generate strength. Prepare five sets of auxiliary devices for cyclical operation.

[0032] Furthermore, welding the bottom end of the support leg 2 to the midpoint of the connection line between the center reserved hole and the four corner bolt holes of the flange 3 can make the distribution of support force more reasonable, help maintain the flatness of the flange 3 during the concrete pouring process, and provide a reliable reference surface for the positioning of the ground cage.

[0033] This invention, through the installation of a support structure welded and fixed to the flange 3 and a horizontal crossbar 1, provides continuous and stable spatial positioning support for the ground cage during the critical stage from the completion of concrete pouring to its complete solidification. This helps reduce displacement caused by the ground cage's own weight and provides structural assurance for maintaining the ground cage's designed position. Simultaneously, the coordinated operation of horizontal adjustment and vertical measurement helps improve the positional accuracy of the ground cage installation, creating favorable conditions for subsequent light pole installation. The construction method of using multiple sets of devices in a cyclical manner can improve equipment utilization efficiency while ensuring construction quality.
