Description

Technical Field

[0001] This application relates to the field of coal mine roadway support equipment technology, and more specifically, to a detachable steel grate and support structure for flexible concrete. Background Technology

[0002] Flexible formwork concrete is a composite structural material formed by filling concrete into a flexible formwork. The flexible formwork and concrete work together to improve the load-bearing capacity and have high compressive and shear strength. It has gradually become the mainstream method of roadway support to ensure the stability and safety of roadways.

[0003] During the construction of flexible formwork concrete, a reinforcing grate is required as lateral support to provide lateral restraint for the freshly poured concrete and prevent large-area bulging. Under traditional construction equipment and methods, the reinforcing grate is a one-piece structure, fixed to the flexible formwork concrete by tie bolts. After the flexible formwork concrete reaches the predetermined curing time, the tie bolts must be removed before the reinforcing grate can be dismantled. This results in low efficiency in grate removal, and during the removal of the tie bolts, the lateral restraint stress provided by the tie bolts to the flexible formwork concrete fails, causing disturbance to the concrete and affecting the support safety of the roadway.

[0004] Therefore, a detachable steel grate and support structure for flexible formwork concrete is needed to solve the above problems. Utility Model Content

[0005] In view of this, the purpose of this application is to propose a detachable steel grate and support structure for flexible formwork concrete, which can provide lateral restraint for the initial stage of flexible formwork concrete pouring without removing the tie bolts, while effectively recovering the steel grate.

[0006] To achieve the above objectives, this application provides a detachable steel grate for flexible formwork concrete, comprising:

[0007] At least two grate bodies, the at least two grate bodies being arranged opposite each other and spaced apart;

[0008] At least one matching plate is disposed between two adjacent grate bodies;

[0009] Multiple first connection assemblies are divided into two groups and are arranged side by side on the surface of the matching plate facing away from the flexible concrete. The first connection assemblies are used to realize the detachable connection between the grate body and the adjacent matching plate.

[0010] Multiple second connection assemblies are arranged sequentially at intervals along the height direction of the matching plate, and the opposite ends of the second connection assemblies are respectively connected to the matching plate and the flexible concrete formwork.

[0011] Optionally, the grate body has a plurality of extension ribs on the side facing the matching plate. The plurality of extension ribs are arranged sequentially at intervals along the height direction of the grate body. Each extension rib abuts against the matching plate and is detachably connected through the first connecting assembly.

[0012] Optionally, the first connection assembly includes a connection block and a plurality of limiting connectors. The connection block and the matching plate enclose a connection channel, and the extension rib can pass through the connection channel. The plurality of limiting connectors are evenly distributed on opposite sides of the connection channel. The limiting connectors are used to detachably connect the connection block to the matching plate to limit the extension rib within the connection channel.

[0013] Optionally, the limiting connector is a screw, and the connecting block and the matching plate have corresponding screw holes, so that the screw can pass through the screw holes and connect the connecting block and the matching plate together.

[0014] Optionally, the first connection assembly and the second connection assembly are arranged at intervals on the mating plate.

[0015] Optionally, the second connection assembly includes tie bolts, which are inserted through the matching plate. The opposite ends of the tie bolts are located on opposite sides of the matching plate and are detachably connected to the flexible concrete formwork and the matching plate, respectively.

[0016] Optionally, the tie bolt is threaded to the flexible concrete template; and / or the tie bolt is threaded to the matching plate.

[0017] Optionally, the tie bolt is provided with a threaded end at one end connected to the matching plate. The threaded end is provided with a tray and a connecting nut. The threaded end passes through the matching plate and the tray. The connecting nut is screwed into the threaded end and rotated until the tray abuts against the matching plate.

[0020] Flexible concrete formwork, wherein flexible concrete formwork is used for pouring to form flexible concrete;

[0021] At least two removable reinforcing bars for flexible concrete as described above are respectively arranged on opposite sides of the flexible concrete.

[0022] As can be seen from the above, the detachable steel grate and support structure for flexible formwork concrete provided in this application have the following advantages compared with the prior art: Using the aforementioned detachable steel grate for flexible formwork concrete, the first connecting assembly enables a detachable connection between the grate body and the matching plate. After the flexible formwork concrete reaches its curing strength, the first connecting assembly can be removed, separating the grate body from the matching plate, allowing for effective recycling of the grate body.

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0034] Figure 1 This is a schematic diagram of a detachable steel grate used for flexible concrete in the first embodiment of this application. Figure 2 for Figure 1 A schematic diagram of the first connection assembly is shown. Figure 3 for Figure 2 A schematic diagram of the second connection assembly is shown. (As shown) Figures 1 to 3 As shown, the detachable steel grate for flexible formwork concrete includes at least two grate bodies 1, at least one matching plate 2, multiple first connection assemblies 3 and multiple second connection assemblies 4.

[0035] At least two grate bodies 1 are arranged opposite each other and spaced apart. The grate bodies 1 are usually made of steel bars, steel pipes, or steel plates. For example, the grate body 1 consists of multiple steel bars arranged in a crisscross pattern, or the grate body 1 consists of a frame and multiple steel bars, which are arranged in a crisscross pattern within the frame. When there are multiple grate bodies 1, the multiple grate bodies 1 are arranged sequentially and spaced apart along the same direction.

[0036] Matching plates 2 are installed between two adjacent grate bodies 1; matching plates 2 are installed between adjacent grate bodies 1 located in the same direction. The opposite sides of the matching plates 2 are in contact with the adjacent grate bodies 1. Typically, the height of the matching plate 2 is less than the height of the grate body 1, the thickness of the matching plate 2 is approximately equal to the thickness of the grate body 1, and the width of the matching plate 2 is 1 / 5 to 1 / 10 of the width of the grate body 1.

[0037] Multiple first connecting assemblies 3 are divided into two groups and arranged side-by-side on the surface of the matching plate 2 facing away from the flexible concrete. The first connecting assemblies 3 are used to achieve a detachable connection between the grate body 1 and the adjacent matching plate 2. One side surface (inner side) of the matching plate 2 and the grate body 1 abuts against the flexible concrete, and the first connecting assemblies 3 are located on the side surface (outer side) of the matching plate 2 facing away from the flexible concrete. One set of first connecting assemblies 3 is located on the left side of the matching plate 2, used to connect the grate body 1 on its left side to the matching plate 2; the other set of first connecting assemblies 3 is located on the right side of the matching plate 2, used to connect the grate body 1 on its right side to the matching plate 2. The grate body 1 is detachably connected to the matching plate 2 via the first connecting assemblies 3. By placing the first connecting assemblies 3 on the side surface (outer side) of the matching plate 2 facing away from the flexible concrete, operation is facilitated and the difficulty of assembly and disassembly is reduced.

[0038] Multiple second connecting assemblies 4 are arranged sequentially at intervals along the height direction of the matching plate 2, and the opposite ends of the second connecting assemblies 4 are respectively connected to the matching plate 2 and the flexible concrete formwork. The grate body 1 is located on the side of the flexible concrete formwork, and the second connecting assemblies 4 are used to connect the matching plate 2 and the flexible concrete formwork together. In one embodiment of this application, the second connecting assemblies 4 include, but are not limited to, tie bolts, i.e., threaded steel bars 403. By increasing the number of second connecting assemblies 4, the connection stability between the matching plate 2 and the flexible concrete formwork can be increased.

[0039] During assembly, the flexible concrete template is centered, and detachable steel bars are provided on opposite sides of the flexible concrete template. The detachable steel bars are used to clamp the flexible concrete template. Then, the matching plate 2 and the flexible concrete template are connected together by the second connecting assembly 4. The second connecting assembly 4 is set along the vertical direction of the matching plate 2. The detachable steel bars in each direction are connected together by the matching plate 2 and the first connecting assembly 3, which connects the grate bodies 1 that are set at intervals. The first connecting assembly 3 is set on the side facing away from the flexible concrete and is set along the horizontal direction of the matching plate 2.

[0040] Then, flexible concrete is poured into the flexible concrete formwork. After the flexible concrete reaches its curing strength, the first connecting assembly 3 is removed, and the grate body 1 is separated from the matching plate 2. At this point, the grate body 1 is effectively recycled. Meanwhile, the matching plate 2, under the action of the second connecting assembly 4, can remain on the flexible concrete without removing the tie bolts. This ensures that the tie bolts provide effective lateral restraint stress to the flexible concrete and avoids disturbing the flexible concrete.

[0041] Using the aforementioned detachable steel grate for flexible formwork concrete, the first connecting assembly 3 enables a detachable connection between the grate body 1 and the matching plate 2. After the flexible formwork concrete reaches its curing strength, the first connecting assembly 3 is removed, separating the grate body 1 from the matching plate 2, allowing for effective recycling of the grate body 1. Simultaneously, the second connecting assembly 4 retains the matching plate 2 on the flexible formwork concrete, providing effective lateral restraint stress and preventing disturbance to the concrete. The detachable steel grate for flexible formwork concrete offers advantages such as ease of application, high practicality, and recyclability, not only improving the recycling efficiency of the grate body 1 but also saving costs and simplifying the construction process.

[0042] Optionally, the grate body 1 has multiple extension ribs 101 on the side facing the matching plate 2. These extension ribs 101 are spaced apart sequentially along the height of the grate body 1. Each extension rib 101 abuts against the matching plate 2 and is detachably connected via a first connecting assembly 3. The extension ribs 101 abut against the surface of the matching plate 2 facing away from the flexible concrete, facilitating the assembly and disassembly of the first connecting assembly 3. The first connecting assembly 3 connects the extension ribs 101 to the matching plate 2. Each extension rib 101 is used in conjunction with one first connecting assembly 3. By increasing the number of extension ribs 101, a stable connection is maintained between the grate body 1 and the matching plate 2.

[0043] In one embodiment of this application, a plurality of extension ribs 101 are sequentially spaced along the height direction on the side of the grate body 1. The extension ribs 101 and the reinforcing bars of the grate body 1 can be an integral structure. Typically, the grate body 1 located at the ends may have extension ribs 101 on only one side, while the grate body 1 located in the middle may have extension ribs 101 on both opposite sides, and the extension ribs 101 are arranged in a mirror-symmetrical manner along the centerline of the grate body 1.

[0044] Optionally, the first connecting assembly 3 includes a connecting block 301 and multiple limiting connectors. The connecting block 301 and the matching plate 2 enclose a connecting channel, through which the extension rib 101 can pass. The multiple limiting connectors are evenly distributed on opposite sides of the connecting channel. The limiting connectors are used to detachably connect the connecting block 301 to the matching plate 2, thereby confining the extension rib 101 within the connecting channel. The connecting channel provides installation space for the extension rib 101. After the extension rib 101 passes through the connecting channel, the limiting connectors confine the extension rib 101 within the connecting channel. When the grate body 1 needs to be removed, only the limiting connectors need to be removed. The connecting block 301 separates from the matching plate 2, the extension rib 101 can exit the connecting channel, and the matching plate 2 separates from the grate body 1.

[0045] In one embodiment of this application, the connecting block 301 may have an arc-shaped groove, which is pressed onto the extension rib 101 to prevent the extension rib 101 from moving in the height direction. Two limiting connectors may be provided, with the two limiting connectors located on the upper and lower sides of the arc-shaped groove respectively, to further enhance the limiting effect.

[0046] Optionally, the limiting connector is a screw 302. The connecting block 301 and the matching plate 2 have corresponding screw holes 302. The screw 302 passes through these holes to connect the connecting block 301 and the matching plate 2 together. The screw 302 has advantages such as being easy to install and remove, providing a stable connection, and is also low in cost.

[0047] In one embodiment of this application, the connecting block 301 is provided with two screw holes 302, and the corresponding position of the first connecting assembly 3 on the matching plate 2 is also provided with two screw holes 302, which are located on the upper and lower sides of the extension rib 101 respectively. When the connecting block 301 is fastened on the extension rib 101, the screw holes 302 on the connecting block 301 correspond one-to-one with the screw holes 302 on the matching plate 2, and are fixed by screws 302 passing through.

[0048] Optionally, the first connecting assembly 3 and the second connecting assembly 4 are arranged at intervals on the matching plate 2. Typically, each pair of first connecting assemblies 3 is connected to the adjacent grate body 1 to meet the connection requirements between the matching plate 2 and the grate body 1; a second connecting assembly 4 is provided between every two pairs of first connecting assemblies 3, and the second connecting assembly 4 can still meet the stress requirements of the flexible concrete when the first connecting assembly 3 is removed.

[0049] In one embodiment of this application, the supporting plate 2 is provided with four pairs of first connecting assemblies 3 and three second connecting assemblies 4, the second connecting assemblies 4 are centrally located and arranged sequentially along the height direction; each pair of first connecting assemblies 3 is located on opposite sides of the second connecting assembly 4.

[0050] Optionally, the second connection assembly 4 includes tie bolts that pass through the matching plate 2. The opposite ends of the tie bolts are located on opposite sides of the matching plate 2 and are detachably connected to both the flexible concrete formwork and the matching plate 2. Before pouring concrete, the tie bolts are connected to the flexible concrete formwork, and then the tie bolts are passed through the matching plate 2, achieving a connection between the matching plate 2 and the side of the matching plate 2 facing away from the flexible concrete. The tie bolts are used to connect the flexible concrete formwork to the outer matching plate 2, bear the lateral pressure of the flexible concrete and other loads, and meet the requirements for integrity, stiffness, and strength.

[0051] Optionally, the tie bolts are threadedly connected to the flexible concrete formwork; and / or the tie bolts are threadedly connected to the matching plate 2. The tie bolts include, but are not limited to, threaded steel bars 403, with threaded ends at both opposite ends of the threaded steel bars 403. Using threaded connections can accelerate the connection process, improve connection stability, and enhance structural strength.

[0052] Optionally, the tie bolt has a threaded end at one end connected to the matching plate 2. A tray 401 and a connecting nut 402 are provided on the threaded end. The threaded end passes through the matching plate 2 and the tray 401. The connecting nut 402 is screwed into the threaded end and rotated until the tray 401 abuts against the matching plate 2. The matching plate 2 has a threaded hole that mates with the threaded end. The threaded end is screwed into the threaded hole. The tray 401 is placed on the surface of the matching plate 2 facing away from the flexible concrete. The connecting nut 402 is screwed into the threaded end and rotated until the tray 401 abuts against the matching plate 2. The tray 401 provides support and restraint for the threaded end, and the connecting nut 402 locks the relative configuration of the tray 401 and the matching plate 2, thereby ensuring connection strength.

[0053] Figure 4 This is a schematic diagram of a detachable steel grate used for flexible formwork concrete in the second embodiment of this application. Figure 5 for Figure 4 The diagram shown illustrates the connection hinge. Figure 6 for Figure 5 The exploded view of the connecting hinge is shown. Figures 4 to 6 As shown, the detachable steel grate for flexible concrete also includes: a third connection assembly 5.

[0054] Optionally, when the detachable steel grate needs to be rotated, the detachable steel grate for flexible concrete also includes multiple third connecting assemblies 5. These assemblies 5 are sequentially arranged along the height of the grate body 1, and are used to achieve a rotatable connection between adjacent grate bodies 1. When the grate bodies 1 are in different directions, the matching plate 2 can be removed, and the third connecting assembly 5 can be installed between the two grate bodies 1. With the third connecting assembly 5 as an axis, the grate bodies 1 can rotate relative to each other, allowing for a fold at any angle between the two grate bodies 1. By increasing the number of third connecting assemblies 5, the timely response of the grate body 1 when rotation is required can be ensured.

[0055] In one embodiment of this application, the third connecting assembly 5 includes, but is not limited to, connecting hinges. The connecting hinges are disposed between adjacent grate bodies 1, and the opposite sides of the connecting hinges are respectively connected to the adjacent grate bodies 1 to realize the rotatable connection of the adjacent grate bodies 1.

[0056] In one embodiment of this application, the connecting hinge includes a bearing 501, a sleeve 502, and a nut 503. The top end of the bearing 501 passes through the sleeve 502, and the bottom end of the sleeve 502 abuts against the base of the bearing 501. The nut 503 is connected to the bearing 501 and is located above the sleeve 502. The bearing 501 and the sleeve 502 are respectively connected to the grate bodies 1 on both sides. By rotating one or both sides of the grate body 1, an included angle θ is formed between adjacent grate bodies 1.

[0057] The following section further describes the application process of the detachable steel grate for flexible formwork concrete.

[0058] When assembling a detachable steel grate, if multiple grate bodies 1 are located in the same direction, adjacent grate bodies 1 only need to be connected together by a matching plate 2 and multiple first connecting assemblies 3. If the detachable steel grate has a folding requirement, a matching plate 2 is not required between the two grate bodies 1 at the folding point; only multiple third connecting assemblies 5 need to be installed.

The first and second grate bodies 1 on the left and right are located at both ends, and two, three, or more grate bodies 1 can be set between the two ends. Taking two as an example, the second grate bodies 1 on the left and the second on the right are set in the middle. A matching plate 2 is set between every two grate bodies 1.

[0060] The leftmost grate body 1 and the leftmost second grate body 1 are connected by a third connecting assembly 5. A matching plate 2 is installed between the leftmost second grate body 1 and the rightmost second grate body 1.
