Description

Technical Field

[0001] This utility model relates to an integral adjustable lantern frame for concrete column construction. Background Technology

[0002] In modern building frame structure construction, concrete columns, as core load-bearing components, are of paramount importance in terms of construction quality. During operations such as rebar tying, formwork erection, and concrete pouring and vibration, safe and stable high-altitude working platforms are essential for workers. Currently, such operations largely rely on on-site steel pipe scaffolding or temporary working frames, which have several drawbacks: First, the erection and dismantling process is cumbersome, consuming significant manpower and time, and resulting in low material turnover efficiency; second, traditional platforms are mostly fixed structures, and their operating space cannot be flexibly adjusted according to column dimensions and construction procedures, often hindering worker operations and affecting construction efficiency; third, safety protection often relies on hanging safety nets, which have poor impact resistance and insufficient reliability, posing a risk of falls from height; finally, scaffolding needs to be repeatedly assembled and disassembled at each construction point, resulting in significant material waste and difficulty in ensuring the standardization and stability of each erection.

[0003] Therefore, there is an urgent need in this field for a construction platform that can overcome the above-mentioned defects. It should have the characteristics of quick assembly and disassembly, high turnover efficiency, safety and reliability, and adjustable operating space to meet the needs of modern industrialized and prefabricated construction.

[0010] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0011] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0012] Reference Figure 1-6 As shown, an integral adjustable lantern frame for concrete column construction is fitted around the concrete column 11 and includes a base system, a three-dimensional frame system, a footboard system, and a guardrail system; wherein, The three-dimensional frame system includes multiple vertically arranged square steel tube columns 6, multiple horizontally arranged transverse truss frames 7, and multiple longitudinal horizontal connecting rods 8. The square steel tube columns 6, transverse truss frames 7, and longitudinal horizontal connecting rods 8 are detachably connected by high-strength bolts 5 to form modular frame standard sections. The transverse truss frame 7 is composed of a square steel tube main body and equilateral angle steel 13 welded to both sides. The three-dimensional frame system contains multiple frame standard sections. The upper and lower adjacent frame standard sections are connected by the end joints of the square steel tube columns 6 and bolts 5, thereby realizing the vertical extension of the frame. The square steel tube columns 6 are pre-drilled with bolt holes for connecting the transverse truss frames 7 and the longitudinal horizontal connecting rods 8.

[0013] Specifically, the core idea of ​​this case is to decompose a complex engineering structure into a series of simple, standard, and easily mass-producible components (such as square steel tube columns 6 of specific lengths, transverse truss frames 7 of several standard sizes, and longitudinal connecting rods 8). All these components are completed in the factory using precision cutting, drilling, and welding (such as welding angle steel 13 to the transverse main trunk), ensuring controllable quality and high precision. At the same time, on-site work is no longer "processing" but "assembly." Construction workers can assemble Lego bricks by simply using a wrench and connecting the corresponding components with high-strength bolts 5 according to the design drawings. This greatly reduces the reliance on the technical level of workers and also reduces the quality and safety hazards caused by on-site cutting and welding. Among them, the transverse truss frame 7 is welded from square steel tubes and angle steel 13 to form a small truss structure. The characteristic of the truss structure is that it uses a triangular geometric invariant system to bear the load, which can achieve great stiffness and strength with less material. This makes the transverse truss frame 7 deform very little when bearing the vertical load from the tread and the horizontal load from the guardrail, providing solid transverse stiffness and stability for the entire frame, which is the key to ensuring overall safety.

[0014] Furthermore, compared to traditional fastener connections that rely on the friction of bolts, which result in uncertainties in node slippage, poor overall rigidity, and limited erection height, the bolt connection in this case is a rigid connection with strong nodes and excellent overall structural integrity. In addition, the bolt connection in this case requires no hot work, making it safe and environmentally friendly, and it can be repeatedly disassembled and reassembled indefinitely.

[0015] The tread system is laid on a horizontal frame layer composed of a three-dimensional frame system; the tread system includes ordinary treads 9 and hooked galvanized treads 10; the two ends of the ordinary treads 9 are fixedly laid on the left and right sides of the frame; the bottom of the hooked galvanized treads 10 is provided with hooks, which can be hooked onto the longitudinal horizontal connecting rod 8, and the hooked galvanized treads 10 are laid on the front and rear sides of the frame; the hooked galvanized treads 10 are slidably connected to the longitudinal horizontal connecting rod 8 through the hooks at their bottom, and their position can be adjusted laterally along the length of the rod.

[0016] Specifically, the pedal system utilizes a combination of hooks and round / square rods. The longitudinal horizontal connecting rod 8 (usually a round or square steel tube) is itself a load-bearing structural component, and the hook of the galvanized pedal 10 with hooks is directly hooked onto it, so that the pedal load is directly transferred to the main structure. The force transmission path is clear and reliable. The "sliding" is achieved because the inner diameter of the hook is slightly larger than the outer diameter of the connecting rod 8, leaving enough clearance to allow sliding. At the same time, the structural design (such as the depth and angle of the hook) prevents the pedal from coming off when subjected to upward or lateral forces.

[0017] The base system includes a base 1 and a vertical guide tube mounted thereon. The bottom layer of the three-dimensional frame system is connected and fixed to the vertical guide tube by bolts 5.

[0018] The guardrail system is installed on the periphery of the three-dimensional frame system by bolts 5; the guardrail system includes multiple guardrail posts 12 and rigid safety guardrails 3 installed between them, and the guardrail posts 12 are vertically installed on the transverse truss frame 7 and / or the longitudinal horizontal connecting rod 8 by bolts 5.

[0019] It also includes a steel staircase 2 and a stair handrail 4. The steel staircase 2 is attached to the horizontal truss frame 7 of the upper and lower floors by hooks at its top, and the stair handrail 4 is installed on one side of the steel staircase 2 by bolts 5.

[0020] The top of the frame is equipped with lifting rings and / or slings for overall hoisting.

[0021] Working principle: First, the prefabricated square steel tube columns 6, horizontal truss frames 7, and longitudinal horizontal connecting rods 8 are quickly assembled on site into a stable modular three-dimensional frame using bolts 5, and then fixed to the base 1. When workers are working on the frame level, they can flexibly adjust the operating space by sliding the hooked galvanized footboard 10 laterally according to the size of the concrete column 11 and the construction needs, while being protected by the surrounding rigid guardrail system. After the construction of this column is completed, the entire frame is lifted up by the top hoisting components, moved horizontally, and fitted onto the next column, achieving efficient turnover and use.

[0022] This utility model also includes a method for installing and reusing a modular prefabricated lantern frame for concrete column construction, the steps of which are as follows: S1: Construction preparation and component prefabrication: Design the frame according to the dimensions of the concrete column 11, and prefabricate all standard components in the factory, including square steel tube columns 6 with pre-drilled bolt holes, horizontal truss frames 7, longitudinal horizontal connecting rods 8, galvanized footboards with hooks 10 and connecting parts. S2: On-site assembly of the first-floor standard section: Connect the four square steel pipe columns 6 and the horizontal truss frame 7 with high-strength bolts 5 to form two side frames. Then, use the longitudinal horizontal connecting rods 8 to connect the two side frames with high-strength bolts 5 to form a three-dimensional frame, and fix the frame to the base 1. S3: Install auxiliary facilities: Hang the steel staircase 2 on the horizontal truss frame 7 and install the stair handrail 4; install the guardrail uprights 12 and safety guardrails 3 on the frame to form rigid protection; lay ordinary treads 9 on the left and right sides of the frame, hook the galvanized treads 10 with hooks on the longitudinal horizontal connecting rods 8 and place them on the front and back sides of the frame. S4: Vertical extension: Repeat steps S2-S3, connect the square steel tube column 6 of the upper standard section to the lower layer with bolts 5, and gradually increase the height to the design working height. S5: Overall Turnover: After completing the construction of the current concrete column 11, disconnect the frame from the ground, use lifting equipment to lift the entire lantern frame as a whole through the hoisting components at the top of the frame, move it horizontally and place it on the next concrete column to be constructed and fix it in place.

[0023] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
