Description

Technical Field

[0001] This utility model relates to the field of building construction, specifically a foldable 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 folded or 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, occupying significant space during transportation and increasing 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 elevation adjustment devices for floor armor joints cannot meet the requirements of efficient and low-cost construction in terms of transportation and recycling convenience, specification versatility and ground adaptability. Utility Model Content

[0007] The technical problem to be solved by the present utility model lies in how to improve the transportation and recycling 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 foldable elevation and flatness adjustment device for floor armor joints, comprising a gantry assembly, an elevation adjustment assembly and a rubber gasket, wherein the gantry assembly comprises two upright columns and a foldable cross beam, the two upright columns and the foldable cross beam form a 冂-shaped gantry structure, and the gantry structure can be folded for storage; the elevation adjustment assembly is located inside the upright columns and can slide up and down along the upright columns, so as to realize elevation adjustment of armor joints and adapt to armor joints of multiple specifications.

[0009] This device creatively arranges the gantry structure of the traditional armor joint adjustment device into a foldable storable gantry assembly, which greatly reduces the storage volume of the armor joint elevation adjustment device, and reduces the costs of storage, logistics packaging and transportation; the elevation adjustment assembly can not only move in the vertical direction to realize elevation adjustment of armor joints, but also move in the horizontal direction to adapt 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 column is a square upright column with a hollow interior, and a long slot is opened along the vertical direction on the inner side of the upright column close to the armor joint.

[0011] As a preferred technical solution of the present utility model, the foldable cross beam is composed of two rectangular plates, the middle part is connected by a hinge, and the left and right ends are connected with the upright columns by hinges.

[0012] The middle part and both ends of the cross beam are connected by hinges, so the device can be stored in the horizontal direction, which reduces the volume, is convenient for handling, and at the same time reduces transportation and storage costs.

[0013] As a preferred technical solution of the present utility model, the gantry assembly further comprises a gantry limit bolt and a gantry hinged block, the gantry limit bolt is located at the connection between the upright column and the foldable cross beam, and is used for fixing the upright column and the cross beam; the gantry hinged block is located at the top of the upright column and is hinged with the foldable cross beam.

[0014] As a preferred technical solution of the present utility model, the rubber gasket is a rubber sheet with a size larger than the bottom area of the upright column, and is located at the bottom side of the upright column.

[0015] 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.

[0016] 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 telescopic 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 located on the outer side of the column, 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 direction as the lead screw rotates. The slider hinge block is located on the side of the elevation control slider. The telescopic horizontal support bracket is 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 telescopic horizontal support bracket, used to fix the telescopic horizontal support bracket to maintain horizontality.

[0017] As a preferred technical solution of this utility model, the telescopic horizontal support bracket includes an inner slider and an outer slider; the outer slider is a block-shaped component with a groove on one side and a sliding groove on the inner sidewall of the groove; the inner slider is a square block-shaped component with a recess on one side and an overall "U" shape, the recessed side can be hinged to the elevation control slider, and the inner slider also has strip-shaped protruding sliding strips on both sides; the inner slider can be inserted into the groove of the outer slider, and the protruding sliding strips can be locked in the sliding groove.

[0018] As a preferred embodiment of this invention, the length of the groove is greater than that of the protruding slide bar, and the outer slider can slide horizontally through the groove.

[0019] As a preferred technical solution of this utility model, the outer slider 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 telescopic horizontal support bracket is stored through a hinge; the gantry limiting bolt is removed, and the crossbeam is stored through a hinge in the middle of the crossbeam and hinges at both ends.

[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 foldable 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 folding, it can be stacked for storage, significantly improving warehouse space utilization and preventing damage during handling caused by non-foldable devices. Simultaneously, the improved space utilization significantly reduces logistics transportation and packaging costs.

[0022] 2. The telescopic horizontal support bracket can slide horizontally, allowing for a horizontal adjustment stroke of ±10cm. It can adapt to various armored seams with width differences within 20cm, eliminating the need to purchase multiple models for different projects. It is better suited to armored seams of different specifications and models, avoiding the drawbacks of traditional armored seam elevation adjustment devices that require "one specification, one customization". This improves the universality of the adjustment device, significantly reduces the types of devices in stock, lowers inventory management costs, and avoids construction delays caused by model mismatch, thereby 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 , 2 As shown in the figure, this utility model discloses a foldable 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 columns 11, folding crossbeams 12, gantry hinge blocks 13, and gantry limiting bolts 14. The columns 11 consist of two hollow cubic columns, positioned opposite each other symmetrically on either side of the armor seam. The inner surface of each column 11 (the side closest to the armor seam) has a long, vertically oriented groove in the center. A mounting groove for the lifting control device 22 is pre-reserved in the upper part of the column. The gantry hinge block 13 is installed in the middle of the upper inner surface of the column, and bolt holes for the gantry limiting bolts 14 are pre-reserved on both sides of the upper inner surface. The folding crossbeam 12 consists of two rectangular plate-like components of a certain thickness: a left crossbeam 121 and a right crossbeam 122. The left crossbeam 121 has a recess, a limiting bolt hole, and a hinge hole in the center of its left side surface; and a protrusion and a hinge hole in the center of its right side surface. The left side of the right crossbeam 122 has a recess and a hinge hole in the middle, and the right side also has a recess, a hinge hole, and a limit bolt hole in the middle. The width of the left and right crossbeams is similar to the width of the column 11. The gantry hinge block 13 is a block structure that can mate with the recesses of the left crossbeam 121 and the right crossbeam 122, and has a pre-drilled hinge hole. The gantry limit bolt 14 can be fixed to the folding crossbeam 12 through the bolt holes pre-drilled in the column 11. During assembly, the left side recess of the left crossbeam 121 and the right side recess of the right crossbeam 122 mate with the gantry hinge block 13, and the hinge connection is completed through the hinge hole; the gantry limit bolt 14, through the bolt holes pre-drilled in the column 11, fixes the left and right crossbeams to the column 11 respectively through the bolt holes on the left side of the left crossbeam 121 and the bolt holes on the right side of the right crossbeam 122. The protruding part on the right side of the left crossbeam 121 mates with the recessed part on the left side of the right crossbeam 122 and is connected through a hinge hole.

[0029] according to Figure 3 As 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 telescopic 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. The rotary handle 23 is rudder-shaped with a handle on the outer ring, located on the outer side of the column, 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 through a long slot. The elevation control slider 24 can move up and down along the long slot. Figure 3As shown, the telescopic horizontal support bracket 25 includes an outer slider 251 and an inner slider 252. The outer slider 251 is a right-angled trapezoid (but not limited to a right-angled trapezoid), with its right-angled side being hollowed out. The two inner sides of the hollowed-out area also have grooves of a certain length. The inner slider 252 is a U-shaped plate-like component, with a recessed left side center containing bolt holes and hinge holes. The right front and right rear sides have protruding slide bars of a certain length. The inner slider 252 can be inserted into the hollowed-out area of ​​the outer slider 251, and the protruding slide bars can be engaged in the grooves of the outer slider, achieving a slide rail connection. The length of the groove is longer than the length of the protruding slide bars, ensuring that the outer slider 251 can slide smoothly within a certain horizontal distance without slipping out. The outer slider 251 and the inner slider 252 together form the telescopic horizontal support bracket 25. The outer slider 251 is located below the armor seam force transmission plate 4 and is used to adjust the armor seam elevation. 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 inner slider 252 through the hinge hole. The slider limit screw 26 fixes the inner slider 252 to the elevation control slider 24 through the bolt hole reserved in the elevation control slider 24. In use, the telescopic horizontal support bracket 25 is placed under the armor seam force transmission plate, and the rotating handle 23 is turned. Under the action of the screw 21, the elevation control slider 24 drives the telescopic horizontal support bracket 25 to move up and down, thereby driving the force transmission plate 4 to adjust the elevation. Since the outer slider 251 can extend and retract horizontally through the groove, when applied to armor seams of different specifications, it is not necessary to equip it with a corresponding specification elevation adjustment device. Only the extension and retraction length of the outer slider 251 needs to be adjusted, which improves the versatility of this device.

[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 fix the main body of the device: Take out the device in its stored state, unfold the two end columns 11 outwards, and unfold the folding crossbeam 12, which is hinged in the middle and at both ends, to a horizontal state; align the corresponding horizontal limiting holes on the columns and crossbeams, insert the gantry limiting bolts 14 and tighten them to complete the fixing of the main body of the device.

[0032] Step 2: Adjust the telescopic horizontal support bracket: Using the rotating handle 23, initially adjust the elevation control slider 24 to a suitable position, and unfold the telescopic 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 inner slider 252, insert the slider limit bolt 27 and tighten it; according to the armor seam specifications, slide the outer slider 251 horizontally so that the outer slider 251 can reach directly below the armor seam force transmission plate.

[0033] Step 3: Adjust the elevation and flatness of the armor seam: Rotate the rotary handle 23, and the elevation control slider 24 will move up and down through the lifting control device 22. The elevation of the armor seam will be adjusted by the telescopic horizontal support bracket 25 until the elevation of the armor seam meets the construction requirements. By fine-tuning the position of the outer slider of the telescopic horizontal support bracket, ensure that the armor seam force transmission plate is flat and meets the construction flatness standard.

[0034] Step 4: Device Storage: After construction is completed, first unscrew the slider limit bolt 27 at the telescopic horizontal support bracket 25, and the bracket will automatically retract inward; then unscrew the gantry limit bolt 14 at the folding crossbeam, move the two side columns 11 inward, and fold the crossbeam; organize the folded device for transportation or storage.

[0035] This utility model application significantly improves the storage capacity of the device by designing the crossbeam and horizontal support bracket of the traditional gantry-type armor seam elevation adjustment device as hinged and foldable, thereby reducing the storage and transportation costs of the armor seam elevation adjustment device. The telescopic horizontal support bracket can be adjusted to a certain extent in the horizontal direction, which can adapt to more specifications of armor seams, avoiding the drawback of the traditional armor seam elevation adjustment device being "one specification, one customization", and greatly reducing the cost of using the device. The use of rubber pads can greatly increase friction and also make the device better adapt to the complex environment under the paving, avoiding slippage under vibration and thus avoiding rework.
