Description

Technical Field

[0001] This utility model relates to the field of construction platform technology, specifically a construction platform used for engineering construction. Background Technology

[0002] Construction platforms are temporary structures or equipment built to achieve specific operational goals. They are widely used in fields such as construction, bridges, water conservancy, and power. Construction platforms can be classified according to their structural form into ground-mounted construction platforms, cantilevered construction platforms, mobile construction platforms, attached lifting construction platforms, suspended construction platforms, and full-span construction platforms. Ground-mounted construction platforms are directly supported on the ground or foundation and consist of a stable frame structure composed of several crisscrossing metal pipes and clamps, with scaffold boards installed on the frame structure.

[0003] In the current technology, the frame structure of the ground-mounted construction platform needs to use right-angle couplers, swivel couplers and butt couplers to connect several metal pipes. Right-angle couplers connect metal pipes that are perpendicular to each other on the same plane, swivel couplers connect metal pipes that are perpendicular to each other at the corner of the frame structure, and butt couplers connect two metal pipes on the same axis. In actual assembly, the angles of the members at the corners of the frame structure need to be precisely adjusted. The arbitrary angle connection characteristics of the swivel fasteners rely on manual alignment, which will result in angle errors, causing the members to deviate from the designed force direction, forming eccentric bending moments, weakening the node stiffness, and thus affecting the load strength of the ground-mounted construction platform. Moreover, each fastener requires manual alignment of the steel pipe, insertion of the fastener, threading of bolts, and tightening with a wrench, which makes assembly and subsequent disassembly difficult. Therefore, a construction platform for engineering construction is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a construction platform for engineering construction. It has the advantages of adapting to the transmission of vertical angular moments and being easy to assemble and disassemble quickly. It solves the problems of the need to accurately adjust the angle of the members at the corners of the frame structure, the reliance on manual alignment for the arbitrary angle connection characteristics of the swivel fasteners, which will result in angle errors, causing the members to deviate from the design force direction, forming eccentric bending moments, weakening the node stiffness, and thus affecting the load strength of the ground-mounted construction platform. In addition, each fastener requires manual alignment of the steel pipe, insertion of the fastener, threading of bolts and tightening with a wrench, which leads to difficulties in assembly and subsequent disassembly.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a construction platform for engineering construction, comprising a connecting cylinder and several metal pipes disposed on the construction platform, wherein the connecting cylinder is provided with connecting components that connect to the metal pipes, and the connecting cylinder is provided with locking components for fixing the angle of the connecting components; The connecting component includes two connecting sections that are symmetrically distributed vertically. A double ring and a single ring are rotatably mounted on the connecting cylinder. Arc-shaped plates that are symmetrically distributed vertically are fixedly connected to the double ring and the single ring respectively, and the two arc-shaped plates are fixedly connected to the opposite end of the double ring and the single ring respectively. The locking component includes two adjusting sleeves rotatably mounted at both ends of the connecting cylinder, and clamping elements for fixing the two arc-shaped plates are installed on the two adjusting sleeves; The clamping components include a double-headed retaining ring and a single-headed retaining ring that are slidably mounted on the connecting cylinder, and the double-headed retaining ring and the single-headed retaining ring are respectively threadedly connected to the adjusting sleeve on the same side.

[0006] Furthermore, two limiting blocks are fixedly installed on the connecting cylinder, and limiting grooves are opened on the inner walls of both the double-headed retaining ring and the single-headed retaining ring, and the limiting grooves are slidably connected to the limiting blocks. Several anti-slip grooves are opened on both adjusting sleeves in a symmetrical distribution along the central axis.

[0007] Furthermore, the two protrusions of the double-headed retaining ring are arc-shaped, and the arc of the arc protrusion on the double-headed retaining ring is 90 degrees; the single protrusion of the single-headed retaining ring is arc-shaped, and the arc of the arc protrusion on the single-headed retaining ring is 180 degrees.

[0008] Furthermore, the arc of both arc plates is 90 degrees, and the arc plate on the double ring is slidably connected to the outer peripheral wall of the single ring, and the arc plate on the single ring is slidably connected to the outer peripheral wall of the double ring.

[0009] Furthermore, both ends of the connecting cylinder are threaded to metal pipes, and the connecting section is threaded to a metal pipe.

[0010] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1. This construction platform for engineering construction uses arc-shaped plates for guidance and precise locking with snap rings to replace manual alignment of fasteners, preventing the members from deviating from the design force direction and reducing eccentric bending moment at the source. Moreover, the locking components achieve zero-gap mechanical locking angle, thereby further improving node stiffness and enhancing the platform's load-bearing strength. 2. This construction platform for engineering construction restricts the rotation of the retaining ring by rotating the adjusting sleeve and the cooperation of the limiting block and the limiting groove, so that the double-headed retaining ring or the single-headed retaining ring can be accurately inserted between the arc plates. This allows the same connection structure to quickly switch between two commonly used nodes, 180-degree straight line and 90-degree right angle, without the need to change parts to adapt to the frame erection needs of multiple fields such as construction and bridges. 3. The construction platform used for engineering construction uses the sliding contact of the arc plates on the double ring and single ring to provide guidance for angle adjustment and limit the offset through the arc contact surface, thereby avoiding radial shaking during angle adjustment, reducing component wear, and extending service life.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Example 1: Please refer to Figure 1-5 In this embodiment, a construction platform for engineering construction includes a connecting cylinder 1 and several metal pipes 3 set on the construction platform. The connecting cylinder 1 is provided with a connecting component 2 that connects to the metal pipes 3, and the connecting cylinder 1 is provided with a locking component 4 for fixing the angle of the connecting component 2.

[0015] Example 2: Please refer to Figure 1-5 Based on Embodiment 1, the connecting component 2 includes two connecting sections 21 that are symmetrically distributed vertically. A double ring 22 and a single ring 23 are rotatably mounted on the connecting cylinder 1. Arc-shaped plates 24 that are symmetrically distributed vertically are fixedly connected to the double ring 22 and the single ring 23 respectively, and the two arc-shaped plates 24 are fixedly connected to the opposite end of the double ring 22 and the single ring 23 respectively. The locking component 4 includes two adjusting sleeves 41 rotatably mounted at both ends of the connecting cylinder 1, and clamping parts 42 for fixing the two arc-shaped plates 24 are installed on the two adjusting sleeves 41. The clamping component 42 includes a double-headed retaining ring 421 and a single-headed retaining ring 422 that are slidably mounted on the connecting cylinder 1, and the double-headed retaining ring 421 and the single-headed retaining ring 422 are respectively threadedly connected to the adjusting sleeve 41 on the same side.

[0016] It should be noted that the angle adjustment is achieved by rotating the double ring 22 and the single ring 23, and then mechanically locked by the clamping part 42. This eliminates manual alignment errors from the structure, integrates the angle adjustment and locking functions, replaces the combination of multiple fasteners, simplifies the node structure, and lays the foundation for quick assembly and disassembly.

[0017] Among them, the two protrusions of the double-headed retaining ring 421 are arc-shaped, and the arc of the arc protrusion on the double-headed retaining ring 421 is 90 degrees. The single-headed retaining ring 422 has a single arc-shaped protrusion, and the arc of the arc protrusion on the single-headed retaining ring 422 is 180 degrees. The 90-degree arc protrusion of the double-headed retaining ring 421 is precisely matched with the gap of the arc plate 24 at the 180-degree node. The 180-degree arc protrusion of the single-headed retaining ring 422 is completely fitted with the clamping space of the arc plate 24 at the 90-degree node, realizing zero-gap locking and preventing node loosening. The two retaining rings have clear division of labor, and the node type can be switched without replacing parts, improving structural adaptability.

[0018] In addition, the arcs of the two arc plates 24 are both 90 degrees, and the arc plates 24 on the double ring 22 are slidably connected to the outer peripheral wall of the single ring 23, and the arc plates 24 on the single ring 23 are slidably connected to the outer peripheral wall of the double ring 22. The arc plates 24 of the double ring 22 and the single ring 23 slide against each other to form a concentric guide structure, ensuring that the connecting joint 21 rotates along the preset trajectory without radial offset when the angle is adjusted. The 90-degree arc plates 24 are adapted to the outer peripheral walls of the double ring 22 and the single ring 23, and the sliding contact surface is smooth, reducing frictional resistance and making the angle adjustment smoother.

[0019] It should be noted that the two ends of the connecting cylinder 1 are threaded to the metal pipe 3 respectively, and the connecting section 21 is threaded to the metal pipe 3. The threaded connection between the connecting cylinder 1, the connecting section 21 and the metal pipe 3 can be quickly tightened and fixed. The connection strength is higher than that of the fastener bolts and it is not easy to loosen. The threaded mating surface can form a sealing effect, reducing the entry of rainwater and dust into the connection part, delaying corrosion and extending the service life of the node.

[0020] Using the above technical solution, the double ring 22 and single ring 23 in the connecting component 2 are concentrically rotated and installed on the connecting cylinder 1. The two connecting sections 21 are fixed to the double ring 22 and single ring 23 respectively. Therefore, rotating the double ring 22 or single ring 23 can drive the connecting section 21 to adjust the included angle. The arc plates 24 on the double ring 22 and single ring 23 slide against each other, which not only provides guidance for angle adjustment, but also limits the offset through the arc contact surface, avoiding radial shaking during angle adjustment. The adjusting sleeve 41 of the locking component 4 is threadedly connected to the clamping part 42. When the adjusting sleeve 41 is rotated, the cooperation between the limiting block 43 and the limiting groove 44 restricts the rotation of the retaining ring, so that the double-headed retaining ring 421 or single-headed retaining ring 422 is accurately inserted between the arc plates 24, and the angle is locked through the mechanical structure.

[0021] Example 3: Please refer to Figure 1-5 Based on Embodiment 2, two limiting blocks 43 are fixedly installed on the connecting cylinder 1. Limiting grooves 44 are opened on the inner walls of the double-headed retaining ring 421 and the single-headed retaining ring 422, and the limiting grooves 44 are slidably connected to the limiting blocks 43. Several anti-slip grooves 411 are opened on the two adjusting sleeves 41, which are symmetrically distributed in a central axis.

[0022] Using the above technical solution, the limiting block 43 and the limiting groove 44 slide together to forcibly restrict the rotational freedom of the double-headed retaining ring 421 and the single-headed retaining ring 422, ensuring that they only move along the axial direction of the connecting cylinder 1, thereby improving the locking and positioning accuracy. The anti-slip groove 411 increases the friction between the hand and the sleeve, making the rotation operation more labor-saving and adaptable to the complex operating environment of the construction site.

[0023] The working principle of the above embodiments is as follows: When using this construction platform for engineering construction, several metal pipes 3 are threadedly connected to both ends of the connecting cylinder 1 and the connecting section 21 respectively. At this time, the double ring 22 and the single ring 23 can rotate freely around the connecting cylinder 1, and the connecting section 21 is in the state of waiting to be adjusted. To assemble a 180-degree straight node, rotate the double ring 22 and the single ring 23 to make the two connecting sections 21 collinear. At this time, the two arc plates 24 are symmetrically opened, and the gap matches the arc protrusion of the double-headed retaining ring 421. Rotate the adjusting sleeve 41 that is threaded to the double-headed retaining ring 421 to move the double-headed retaining ring 421 toward the arc plate 24 until the arc protrusion of the double-headed retaining ring 421 is engaged in the gap between the two arc plates 24, thereby completing the angle fixation. To assemble a 90-degree right-angle node, rotate the double ring 22 and the single ring 23 until the two connecting sections 21 are perpendicular. At this point, the edges of the two arc plates 24 are in complete contact, forming a clamping space that matches the protrusion of the single-head retaining ring 422. Rotate the adjusting sleeve 41 on the same side of the single-head retaining ring 422 until the arc protrusion of the single-head retaining ring 422 is inserted into the clamping space, so that the 180-degree arc protrusion is clamped by the two fitting arc plates 24, thus completing the angle fixation.
