Description

Technical Field

[0001] This utility model relates to the field of building construction, specifically a detachable floor armor joint elevation and flatness adjustment device. Background Technology

[0002] In the construction industry, especially in locations with high requirements for floor durability, flatness, and maintenance cost control, such as hospitals, underground parking garages, and industrial plant floors, the industry commonly uses floor armor joints to guide and buffer floor deformation and prevent structural damage, in order to minimize cracking or deformation caused by factors such as temperature changes, loads, and foundation settlement. During the installation and subsequent maintenance of floor armor joints, elevation and flatness adjustment devices are needed to calibrate the height difference and flatness of the armor joints, ensuring a smooth floor surface that meets the requirements for passage, load-bearing capacity, and aesthetics. Therefore, the adjustment device is a key auxiliary component in the construction of armor joints. Currently, most floor armor joint elevation and flatness adjustment devices on the market are one-piece molded designs. While these devices can achieve basic elevation and flatness adjustment functions, they have significant limitations in practical applications.

[0003] The patent publication number CN217175560U, entitled "An Auxiliary Installation Support Structure for Floor Armor Joints," describes a fixed, integrated structure consisting of a base plate, frame columns, and elevation components. This structure cannot be stored after use. When constructing large-area floors (such as factories, warehouses, and plazas), numerous adjustment devices are required. The integrated structure results in a fixed device volume, occupies significant space during transportation, and increases logistics packaging and transportation costs. Furthermore, the devices are difficult to stack or compress after construction, leading to low space utilization. Additionally, the non-foldable structure makes the devices susceptible to damage during handling.

[0004] The patent publication number CN223189979U, entitled "An Automatic Device for Adjusting the Height of Armored Joints in Flooring," describes a frame consisting of two fixed-spaced columns and a top beam. The elevation can only be controlled by a lifting slider, and the horizontal adjustment range of the device is fixed, making it inflexible for various sizes of armored joints. Construction companies must customize or purchase corresponding models of adjustment devices for different sizes of armored joints, increasing procurement costs and inventory management difficulties.

[0005] The patent publication number CN214246505U, "An Armored Seam Adjustment Device", adopts a hard steel plate design, which has insufficient friction with the ground. Under the influence of construction vibration, it is prone to slippage, making the base not fit tightly with the ground. This not only affects the flatness accuracy of the armored seam height adjustment, but may also cause the device to be unstable due to the slippage of the base, increasing the risk of construction rework.

[0006] In conclusion, the existing floor armor joint elevation adjusting devices cannot meet the requirements of efficient and low-cost construction in terms of transportation and recovery convenience, specification versatility and ground adaptability. Utility Model Content

[0007] The technical problem to be solved by the present utility model is how to improve the transportation and recovery efficiency and adapt to armor joints of multiple specifications.

[0008] To solve the above technical problem, the present utility model provides the following technical solution: a detachable elevation and flatness adjusting device for floor armor joints, comprising a gantry assembly, an elevation adjusting assembly and a rubber gasket, characterized in that: the gantry assembly comprises two upright posts and a detachable cross beam, the two upright posts and the detachable cross beam form an inverted U-shaped gantry structure, which can realize detachable storage of the upright posts and the cross beam and adapt to armor joints of multiple specifications; the elevation adjusting assembly is located inside the upright posts and can slide up and down along the upright posts to realize elevation adjustment of the armor joints.

[0009] The device creatively arranges the gantry structure of the traditional armor joint adjusting device into a detachable gantry assembly, which greatly reduces the volume of the armor joint elevation adjusting device, and reduces the costs of storage, logistics packaging and transportation. Since the upright posts can move horizontally along the cross beam, the device can also be applied to armor joints of different specifications, which can reduce procurement cost and storage difficulty.

[0010] As a preferred technical solution of the present utility model, the upright posts are hollow square upright posts, and a long slot is opened along the vertical direction on the inner side of the upright post close to the armor joint.

[0011] As a preferred technical solution of the present utility model, the detachable cross beam is a "long U-shaped" rectangular beam member with one open end and one closed end, and a chute is further provided on the inner wall of the open end of the detachable cross beam.

[0012] As a preferred technical solution of the present utility model, the gantry assembly further comprises a horizontal adjusting slider, the horizontal adjusting slider is located at the top of the upright post, and cooperates with the chute of the detachable cross beam to drive the upright post to slide horizontally along the direction of the cross beam.

[0013] The detachable cross beam cooperates with the horizontal adjusting slider, which can realize detachable storage of the cross beam, reduce the volume, facilitate handling, and meanwhile reduce transportation and storage costs.

[0014] As a preferred technical solution of the present utility model, the gantry assembly further comprises a gantry fixing bolt, the gantry fixing bolt is located at the top of the horizontal adjusting slider and is used for fixing the detachable cross beam and the upright posts.

[0015] As a preferred technical solution of this utility model, the rubber pad is a rubber sheet with a size larger than the bottom area of ​​the column and is located on the bottom side of the column.

[0016] Rubber pads can enhance adhesion and friction with the ground, improve adaptability to construction scenarios, and avoid problems such as slippage under construction vibration and poor adhesion between the base and the ground caused by the steel plate design at the bottom of the column of the traditional armored seam elevation adjustment device.

[0017] As a preferred technical solution of this utility model, the elevation adjustment assembly consists of two sets, both located inside the column. Each elevation adjustment assembly includes a rotating handle, a lead screw, a lifting control device, a horizontal support bracket, an elevation control slider, a slider hinge block, and a slider limiting bolt. The lead screw is located inside the column. The lifting control device is located at the top of the lead screw and inside the column. The rotating handle is connected to the lifting control device and is used to drive the lead screw to rotate. The elevation control slider is penetrated by the lead screw, located inside the column, and can slide up and down along the column's long groove as the lead screw rotates. The slider hinge block is located on the side of the elevation control slider. The horizontal support bracket is a square block-shaped component with a recess on one side, hinged to the elevation control slider via the slider hinge block, and slides up and down with the elevation control slider. The slider limiting bolt is located between the elevation control slider and the horizontal support bracket, used to fix the horizontal support to maintain horizontality.

[0018] As a preferred technical solution of this utility model, the rotating handle is located on the front or rear side of the column.

[0019] As a preferred technical solution of this utility model, the horizontal support bracket can support the armor seam force transmission plate.

[0020] As a preferred technical solution of this utility model, the slider limiting bolt is removed, and the horizontal support bracket is stored through a hinge; the gantry fixing bolt is loosened, and the horizontal adjusting slider drives the detachable crossbeam to slide out from the column, thereby realizing the storage of the gantry structure.

[0021] The advantages of this utility model are: 1. Traditional armor seam height adjustment devices are integrally molded, resulting in a fixed device size, large space occupation during transportation, and increased logistics packaging and transportation costs. This application creatively proposes a detachable gantry structure design, allowing the device to be quickly stored. When not in use, the device's volume can be compressed to 1 / 3-1 / 2 of its unfolded state. After disassembly, it can be stacked for storage, significantly improving warehouse space utilization and avoiding damage during handling caused by non-foldable devices. Furthermore, the improved space utilization significantly reduces logistics transportation and packaging costs.

[0022] 2. The horizontal adjustment slider can slide horizontally along the detachable crossbeam, adapting to various armored seams. It eliminates the need to purchase multiple models for different projects, making it more suitable for armored seams of different specifications. This avoids the drawback of traditional armored seam elevation adjustment devices that require "one specification, one customization," improving the universality of the adjustment device, significantly reducing the types of devices in stock, lowering inventory management costs, and preventing construction delays caused by model mismatch, thus improving on-site construction efficiency.

[0023] 3. The rubber pads allow the device to fit as closely as possible to the ground, and can accommodate small stones and debris with a diameter of 10mm or less. This changes the contact between the device and the ground from point contact with the existing rigid base to surface contact, reducing flatness adjustment errors and meeting the requirements of high-precision construction. The rubber material also significantly increases the friction between the base and the ground, simplifying the fixing process and preventing deviations in the armor seam elevation caused by device slippage, thus reducing rework rates.

[0026] 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.

[0027] like Figure 1-3 As shown in the figure, this utility model discloses a detachable floor armor seam elevation and flatness adjustment device, including a gantry assembly 1, an elevation adjustment assembly 2, and a rubber pad 3. The elevation adjustment assembly 2 is located inside the gantry assembly, and the rubber pad 3 is located at the bottom of the gantry assembly.

[0028] Specifically, the gantry assembly 1 includes uprights 11, a detachable crossbeam 12, a horizontal adjustment slider 13, and gantry fixing bolts 14. The uprights 11 consist of two hollow cubic columns, positioned symmetrically opposite each other on either side of the armor seam. The inner surface of each upright 11 (the side closest to the armor seam) has a long, vertically oriented groove in the center, with a pre-reserved mounting slot for the lifting control device 22 in the upper part of the column. Combined with… Figure 4 and Figure 5 It can be seen that the detachable crossbeam 12 is a rectangular beam, with a long groove running through its length along its upper and lower surfaces, extending from one end of the detachable crossbeam 12 to near the other end, making the detachable crossbeam 12 generally U-shaped. The width of the long groove is the same as the width of the horizontal adjusting slider 13. The inner walls of the long groove of the detachable crossbeam have grooves on both sides corresponding to the length of the long groove. Combined with... Figure 6 As can be seen, the horizontal adjusting slider 13 is a rectangular block component with a width consistent with the width of the long groove of the detachable crossbeam 12. It is located on the top plane of the column 11. A protruding strip is provided on the long side of the upper plane of the slider, which cooperates with the sliding groove of the detachable crossbeam 12, allowing the horizontal adjusting slider 13 to drive the column 11 to slide horizontally along the detachable crossbeam 12. The gantry fixing bolt 14 is located on top of the horizontal adjusting slider 13, and can fix the detachable crossbeam 12 and the horizontal adjusting slider 13 by tightening. In use, this device can significantly reduce the size of the device by utilizing its detachable performance, improving space utilization and reducing storage and transportation costs. Simultaneously, the column can move horizontally along the crossbeam, allowing for adjustment of the column spacing to accommodate different specifications of armored seams, significantly reducing equipment procurement costs.

[0029] according to Figure 2As shown, the elevation adjustment assembly 2 includes a lead screw 21, a lifting control device 22, a rotary handle 23, an elevation control slider 24, a horizontal support bracket 25, a slider hinge block 26, and a slider limit bolt 27. The lead screw 21 is a threaded rod located inside the column 11. The lifting control device 22 is located at the top of the lead screw and is placed in a pre-reserved mounting slot on the column 11. The rotary handle 23 is rudder-shaped with a handle on its outer ring, located on the front side of the column 11, and connected to the lifting control device 22 to control the rotation of the lead screw. The elevation control slider 24 is a rectangular block component, with the lead screw 21 penetrating its center. A hinge block mounting slot and bolt holes are pre-reserved in the center of its right side. Most of the elevation control slider 24 is placed inside the column 11, with a portion on its right side protruding from the inner side of the column 11 through a long slot. The elevation control slider 24 can move up and down along the long slot. Figure 7 As can be seen, the horizontal support bracket 25 is a U-shaped plate component with a recessed left side center, and bolt holes and hinge holes are reserved. The slider hinge block 26 is fixed to the hinge block mounting slot on the right side of the elevation control slider 24, and is hinged to the horizontal support bracket 25 through the hinge holes. The slider limit screw 26 fixes the horizontal support bracket 25 to the elevation control slider 24 through the bolt holes reserved in the elevation control slider 24. In application, the horizontal support bracket 25 is placed under the armor seam force transmission plate 4, and the rotating handle 23 is turned. Under the action of the screw 21, the elevation control slider 24 drives the horizontal support bracket 25 to move up and down, thereby driving the force transmission plate to adjust the elevation.

[0030] Rubber gasket 3 is a rubber sheet with a size larger than the bottom area of ​​the column. During production, it is fixed to the bottom side of the column as an integral part.

[0031] The specific steps for using the device according to this embodiment of the utility model are as follows: Step 1: Unfold and make preliminary adjustments to the device and armor seam position: Take out the device in its stored state, align the detachable crossbeam 12 with the horizontal adjustment slider 13 at the top of the column; slide the column 11 left and right to adjust the horizontal distance between the column 11 and the crossbeam, and make preliminary adjustments to the device and armor seam position to roughly adapt to the current armor seam specifications.

[0032] Step 2: Fix the horizontal support bracket: Use the rotating handle 23 to initially adjust the elevation control slider 24 to a suitable position, and unfold the horizontal support bracket 25 hinged to the elevation control slider 24 to a horizontal state; align the limit bolt holes on the elevation control slider 24 and the horizontal support bracket 25, insert the slider limit bolt 27 and tighten it so that the bracket can stably support the force transmission plate of the armor seam.

[0033] Step 3: Adjust the armor seam elevation: Rotate the rotary handle 23, and the elevation control slider 24 will move up and down through the lifting control device 22. The horizontal support bracket 25 will then adjust the armor seam elevation until it meets the construction requirements.

[0034] Step 4: Adjust the flatness of the armor seam: Use the slide to fine-tune the position of the column 11 and the detachable crossbeam 12, insert the gantry fixing bolt 14 and tighten it to complete the precise contact between the horizontal support bracket and the armor seam force transmission plate, and ensure that the flatness of the armor seam meets the standard.

[0035] Step 5: Device Storage: After construction is completed, first unscrew the slider limit bolt 27 at the horizontal support bracket, and the bracket will automatically retract inward; then unscrew the gantry fixing bolt 14 and slide the detachable crossbeam 12 off the column; sort the separated column and crossbeam for transportation or storage.

[0036] This utility model significantly improves the storage capacity of the device by making the crossbeam of the traditional gantry-type armor seam elevation adjustment device detachable, thus reducing the storage and transportation costs. Simultaneously, the application of a horizontal adjustment slider allows the device to adapt to a wider range of armor seam specifications, avoiding the drawback of traditional armor seam elevation adjustment devices requiring only one specification and thus significantly reducing operating costs. The use of rubber pads greatly increases friction and allows the device to better adapt to the complex environment under paved surfaces, preventing slippage under vibration and thus avoiding rework.
