Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a convenient and movable construction material stacking rack. Background Technology

[0002] Construction material storage racks are specialized facilities on construction sites used for the standardized storage and management of construction materials. They are used to store materials such as reinforcing bars, formwork, pipes, and hardware in designated areas. This prevents mixing and improves retrieval efficiency, prevents safety hazards such as slippage and collapse caused by haphazard stacking, and protects materials from damage such as moisture and contamination. Standardizing the site layout helps maintain cleanliness, avoids obstructing passageways or work areas, and meets safety and civilized construction standards. Furthermore, by storing materials off the ground (for rust prevention of metals), using ventilation designs (for mildew prevention of wood), and employing rain and sun protection racks (such as waterproof membranes), the lifespan of materials is extended, thereby ensuring construction safety, quality, and cost control.

[0003] Existing construction material storage racks are mainly divided into two types: fixed and mobile. Fixed storage racks have strong load-bearing capacity but poor flexibility. Mobile storage racks can be adjusted in position by rollers or slide rails, but they occupy a lot of space, which can easily lead to crowding and inconvenience in small construction sites. Moreover, when storing building materials such as steel bars and steel pipes, they are prone to rolling down and injuring construction workers.

[0004] Therefore, those skilled in the art have provided a conveniently movable construction material stacking rack to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a conveniently movable construction material stacking rack. This stacking rack can adapt to different space requirements by adjusting its horizontal and vertical lengths, thereby improving the flexibility of construction. At the same time, the design of the limiting mechanism effectively prevents steel bars and steel pipes from rolling off.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a construction material stacking rack that is easy to move, comprising a limiting mechanism and four positioning mechanisms. Each of the front and rear ends and the left and right sides of the limiting mechanism is slidably provided with an unfolding mechanism. Each of the unfolding mechanisms slidably provided at the front and rear ends of the limiting mechanism is fixedly provided with a support plate. Multiple limiting grooves are opened on both sides of the two support plates. The four unfolding mechanisms are respectively slidably within the four positioning mechanisms.

[0007] The limiting mechanism includes a main frame, with sliding grooves on the front, rear, and sides of the main frame. A telescopic rod is fixedly installed at the center of the upper surface of the main frame, and a telescopic plate is fixedly installed at the upper end of the telescopic rod. Limiting blocks are hinged to the front and rear sides of the telescopic plate, and the four limiting blocks are respectively engaged in multiple limiting grooves opened on both sides of the two support plates.

[0008] Furthermore, the four unfolding mechanisms include an unfolding frame, and a second sliding block is fixedly disposed at the center of the front end of the unfolding frame, the second sliding block sliding inside the first sliding groove.

[0009] Furthermore, each of the two sides of the unfolding frame is fixedly provided with a sliding block, and the upper surface of the two sliding blocks is provided with multiple positioning holes.

[0010] Furthermore, the four positioning mechanisms include positioning frames and positioning blocks. The upper surface of the positioning frame is provided with a through hole, and the front end and the other side of the positioning frame are provided with sliding grooves.

[0011] Furthermore, a round shaft is fixedly provided at the lower center of the positioning block, and the round shaft passes through a through hole to the interior of the second slide groove.

[0012] Furthermore, grooves are provided on the upper sides of both sides of the positioning frame, and both sides of the positioning block are engaged in the two grooves.

[0013] Furthermore, a baffle is fixedly installed in the middle of the upper end face of the positioning frame.

[0014] This utility model has the following beneficial effects:

[0015] 1. The present invention proposes a convenient mobile construction material stacking rack. Compared with existing construction material stacking racks, this stacking rack adjusts the lateral length of the stacking rack by using the front and rear unfolding mechanisms of the moving limiting mechanism, and adjusts the longitudinal length of the stacking rack by using the unfolding mechanisms on both sides of the moving limiting mechanism. In this way, the stacking rack can adapt to construction environments of different sizes. In addition, the structural stability of the material stacking rack can be ensured by fixing the round shaft.

[0016] 2. The present invention proposes a convenient mobile construction material stacking rack. Compared with existing construction material stacking racks, this stacking rack pushes the telescopic plate downward to make it contact the reinforcing bars and steel pipes, and then rotates the limiting blocks on both sides of the telescopic plate to rotate it into the limiting groove, thereby fixing the position of the telescopic plate. In this way, the reinforcing bars and steel pipes are effectively prevented from rolling off, reducing the risk of material accidents. Attached Figure Description

[0023] 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.

[0024] Reference Figure 1 An embodiment of this utility model provides a convenient mobile construction material stacking rack, including a limiting mechanism 1 and four positioning mechanisms 3. Each of the front and rear ends and the left and right sides of the limiting mechanism 1 is slidably provided with an unfolding mechanism 2. Each of the unfolding mechanisms 2 slidably provided at the front and rear ends of the limiting mechanism 1 is fixedly provided with a support plate 4. Multiple limiting grooves 5 are opened on both sides of the two support plates 4. The four unfolding mechanisms 2 are respectively slidably in the four positioning mechanisms 3.

[0025] Specifically, construction workers can adjust the lateral length of the stacking rack by moving the front and rear unfolding mechanisms 2 of the limiting mechanism 1. When the unfolding mechanism 2 is moved, the positioning mechanisms 3 on both sides will move accordingly, thereby adjusting the width of the entire stacking rack. In addition, construction workers can also move the unfolding mechanisms 2 on both sides of the limiting mechanism 1 to drive the positioning mechanisms 3 at both ends, thereby adjusting the longitudinal length of the stacking rack.

[0026] Reference Figure 1 , Figure 2 , Figure 3The limiting mechanism 1 includes a main frame 101. The main frame 101 has sliding grooves 102 at the front, rear and sides. A telescopic rod 103 is fixedly installed at the center of the upper surface of the main frame 101. A telescopic plate 104 is fixedly installed at the upper end of the telescopic rod 103. Limiting blocks 105 are hinged to the front and rear sides of the telescopic plate 104. The four limiting blocks 105 are respectively engaged in the multiple limiting grooves 5 opened on both sides of the two support plates 4.

[0027] Specifically, construction workers push the telescopic rod 103 downwards to move the telescopic plate 104, which then comes into contact with the reinforcing bars and steel pipes placed on the main frame 101. Next, the limiting blocks 105 hinged on both the front and rear ends of the telescopic plate 104 are rotated into the limiting grooves 5. In this way, the position of the telescopic plate 104 is fixed, thereby effectively preventing the reinforcing bars and steel pipes from rolling off. In addition, the length of the telescopic plate 104 can be manually adjusted at both the front and rear ends.

[0028] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 The four unfolding mechanisms 2 include an unfolding frame 201. A sliding block 204 is fixedly installed at the middle of the front end of the unfolding frame 201. The sliding block 204 slides inside the sliding groove 102. Sliding blocks 1 203 are fixedly installed on both sides of the unfolding frame 201. Multiple positioning holes 202 are opened on the upper surface of the two sliding blocks 1 203.

[0029] Specifically, the sliding block 204 at the front end of the unfolding frame 201 slides inside the slide groove 102, which facilitates the movement of the unfolding frame 201. The sliding blocks 203 on both sides of the unfolding frame 201 slide inside the slide groove 302. When the construction personnel move the unfolding frame 201, the sliding block 203 will drive the positioning mechanism 3 to move together. In addition, the multiple positioning holes 202 on the upper surface of the sliding block 203 cooperate with the round shaft 305 to fix the unfolding mechanism 2. The unfolding frame 201 is made of high-strength alloy steel.

[0030] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 The four positioning mechanisms 3 include a positioning frame 301 and a positioning block 304. The upper end face of the positioning frame 301 is provided with a through hole 306. The front end and the other side of the positioning frame 301 are provided with a second sliding groove 302. A round shaft 305 is fixedly installed in the middle of the lower end of the positioning block 304. The round shaft 305 passes through the through hole 306 and extends into the second sliding groove 302. Grooves are provided on the upper sides of the positioning frame 301. The two sides of the positioning block 304 are engaged in the two grooves. A baffle 303 is fixedly installed in the middle of the upper end face of the positioning frame 301.

[0031] Specifically, the construction workers pass the round shaft 305 through the through hole 306 opened on the positioning frame 301 and into the positioning hole 202. In this way, the positions of the positioning mechanism 3 and the unfolding mechanism 2 can be fixed. Then, the two sides of the positioning block 304 are respectively inserted into the grooves opened at the upper ends of the two sides of the positioning frame 301. By engaging the positioning block 304 in the groove, the positioning block 304 is fixed. In addition, the baffle 303 serves to block the construction materials and prevent them from slipping out. The positioning frame 301 is also made of high-strength alloy steel.

[0032] Working principle: The construction worker grasps the positioning block 304 and pulls it upward, causing the round shaft 305 to be pulled out of the through hole 306. Then, the unfolding frame 201 at the front and rear ends of the main frame 101 is pushed towards the center, causing the positioning frames 301 on both sides to move synchronously, thereby adjusting the lateral length of the material stacking rack. Next, the unfolding frames 201 on both sides of the main frame 101 are pushed towards the center, causing the positioning frames 301 to move to adjust the longitudinal length. After the adjustment is completed, the round shaft 305 is passed through the through hole 306 and the positioning hole 202 in sequence for fixation. Then, the construction worker places the steel bars and steel pipes on the limiting mechanism 1 and the unfolding mechanism 2, pushes the telescopic plate 104 downward until it contacts the materials, and then rotates the limiting block 105 into the limiting groove 5 to lock the position of the telescopic plate 104, thereby fixing the steel bars and steel pipes and preventing them from rolling off.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
