Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a steel pipe base for protective scaffolding on building construction sites. Background Technology

[0002] Construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of buildings, or the process of turning the lines on design drawings into physical objects at designated locations. It includes foundation construction, main structure construction, roof construction, and decoration construction. The place where construction work is carried out is called the "construction site" or "construction site." Construction is a production activity carried out by people using various building materials and machinery and equipment according to specific design blueprints within a certain space and time to build various types of building products. It includes the entire production process from construction preparation and groundbreaking to project completion and acceptance. This process involves construction preparation, construction organization design and management, earthwork, blasting, foundation engineering, reinforcement engineering, formwork engineering, scaffolding engineering, concrete engineering, prestressed concrete engineering, masonry engineering, steel structure engineering, timber structure engineering, and structural installation engineering. The scaffolding steel pipe base is an important component that supports the entire scaffolding. Its main function is to distribute the weight of the scaffolding and fix it to the ground, thereby ensuring the stability and safety of the scaffolding.

[0003] Existing equipment, such as CN221481367U, describes an adjustable scaffolding steel pipe base designed to prevent loosening. This base includes a base plate with an angle adjustment seat at its center. A vertical screw is hinged to the angle adjustment seat, and the screw is fixed to the angle adjustment seat by screw bolts. A support nut is threaded onto the vertical screw. An annular limiting groove is provided on the upper surface of the angle adjustment seat. Several movable support arms are hinged to the outer circumference of the support nut, with the lower ends of the movable support arms contacting the annular limiting groove. This invention uses three movable support arms to support the support nut on the vertical screw, preventing loosening. The annular limiting groove, with its vortex structure, guides and limits the movement of the movable support arms, allowing them to rotate with the support nut and be limited in real time. The angle adjustment and positioning of the vertical screw are achieved by the engagement of the first meshing tooth on the angle adjustment seat with the second meshing tooth at the bottom of the vertical screw.

[0004] When workers need to install scaffolding, they place a base on the ground so that they can install the scaffolding on the base. However, due to uneven ground, the existing bases require workers to constantly adjust the angle of the base during installation, which increases the workload of the workers. Utility Model Content

[0005] The purpose of this utility model is to solve the problem of increased labor for workers installing scaffolding in the existing technology, and to propose a steel pipe base for protective scaffolding at construction sites.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a steel pipe base for protective scaffolding at a construction site, comprising a base, a hollow pipe, a main sleeve, and an adjusting device. The hollow pipe is inserted inside the main sleeve, the base is positioned below the main sleeve, and the adjusting device is positioned on the surface of the base. The adjusting device includes an adjusting sleeve, which is fixedly connected to the top of the base. An adjusting ball is fixedly connected to the bottom of the main sleeve, and the adjusting ball is rotatably connected to the interior of the adjusting sleeve. Multiple support sleeves are fixedly connected to the surface of the adjusting sleeve. A storage groove is provided inside the adjusting sleeve, and the storage groove communicates with the support sleeves. A threaded hole is provided on the surface of the support sleeve, and a threaded rod is threadedly connected to the inner side of the threaded hole. A stop block is fixedly connected to one end of the threaded rod, and the stop block is slidably connected to the interior of the storage groove. The stop block is inserted into the surface of the adjusting ball. A hexagonal block is fixedly connected to the end of the threaded rod away from the adjusting ball, and the hexagonal block is located on one side of the support sleeve. The hexagonal block can cooperate with the threaded rod to achieve the purpose of adjusting the threaded rod.

[0007] Preferably, the surface of the main sleeve is provided with a limiting device, the limiting device including a support ring, the support ring being fixedly connected to the surface of the main sleeve, a limiting sleeve being placed on the surface of the support ring, the limiting sleeve being rotatably connected to the surface of the main sleeve, and the support ring being able to cooperate with the main sleeve to achieve the purpose of fixing the support ring.

[0008] Preferably, a guide sleeve is fixedly connected to the surface of the limiting sleeve. The guide sleeve is located between the two support rings and can cooperate with the limiting sleeve to achieve the purpose of fixing the guide sleeve.

[0009] Preferably, an insert plate is placed inside the guide sleeve, and a limiting block is fixedly connected to the surface of the insert plate. The limiting block is slidably connected to the inside of the guide sleeve, and the insert plate can cooperate with the guide sleeve to achieve the purpose of guiding the insert plate.

[0010] Preferably, an elastic plate is fixedly connected to the surface of the insert plate. The elastic plate is placed on the surface of the guide sleeve, and the elastic plate can cooperate with the insert plate to achieve the purpose of fixing the elastic plate.

[0011] Preferably, the surface of the main sleeve is provided with a positioning hole, and the insert plate is inserted into the interior of the positioning hole. The positioning hole can cooperate with the main sleeve to achieve the purpose of storing the insert plate.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting an adjustment device, rotating the main sleeve drives the adjustment ball, which rotates inside the adjustment sleeve. When the main sleeve is tilted at a certain angle, rotating the hexagonal block drives the threaded rod. The threaded rod is guided by the threaded hole and extends, pushing the abutment block. The abutment block slides inside the receiving groove. When the abutment block slides to the designated position, it abuts against the adjustment ball. By setting an adjustment device, it is possible to effectively facilitate workers to adjust the angle of the base, avoiding the need for workers to constantly adjust the base when installing scaffolding, thereby reducing the workload of workers installing scaffolding.

[0014] 2. In this utility model, by setting a limiting device, the worker inserts the pin into the slot on the surface of the main sleeve. The pin passes through the hollow tube. The limiting sleeve rotates on the support ring, and the main sleeve guides the limiting sleeve. When the limiting sleeve rotates to a certain angle, the limiting sleeve blocks the slot on the surface of the main sleeve, pushing the insert plate. The insert plate pushes the elastic plate. The elastic plate is squeezed during the sliding process and opens. When the insert plate is inserted into the positioning hole, the elastic plate resets and clamps the guide sleeve. By setting a limiting device, it is possible to effectively limit the pin for the worker, avoiding the time-consuming situation when limiting the pin, thereby improving the efficiency of the worker in installing scaffolding.
