Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to an installation node for an arc-shaped composite slab structure. Background Technology

[0002] Composite floor slabs are assembled monolithic floor slabs made by stacking precast slabs and cast-in-place reinforced concrete layers. Curved (arc-shaped) composite slabs, as a special type of composite slab structure, may be installed in an upward or downward bent state depending on the design requirements.

[0003] In existing technologies, when installing curved composite panels onto a wall, specifically when connecting the ends of the curved composite panels to the top of the wall, a combination of hoisting and support methods is used. Specifically, if the design requires a downward bend, a reverse semi-circular (convex) steel frame needs to be installed on the base floor; if the design requires an upward bend, a forward semi-circular (concave) steel frame needs to be installed on the base floor. During hoisting installation, it is also necessary to ensure the position and level of the curved composite panels, as well as the firmness of the connections. However, constructing this steel frame requires significant space, time, and material costs; furthermore, during construction, multiple adjustments to the support height at various support points are required to ensure the curvature of the convex or concave support surface of the steel frame. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an arc-shaped composite panel installation node, which allows for relatively quick installation of the arc-shaped composite panel onto a wall, reducing time, material, and space costs.

[0005] According to an embodiment of the present invention, an arc-shaped composite panel mounting node is provided for assisting in the installation of an arc-shaped composite panel onto a wall. The arc-shaped composite panel mounting node includes a bottom support unit disposed on the wall, the bottom support unit comprising:

[0006] The bottom mounting component is installed on one end of the wall and extends laterally to form a cantilever.

[0007] Vertical support rods are provided at intervals, and their lower ends are fixed to the cantilever end of the bottom mounting component;

[0008] And a top support assembly, which has multiple components, each located at the top of a number of vertical support rods, to support the underside of the curved composite plate.

[0009] Preferably, the top support component includes:

[0010] The middle support rod is fixed at its lower end to the vertical support rod;

[0011] And elastic support rods, with multiple rods arranged circumferentially in the middle support rod, and the middle support rod and elastic support rods are simultaneously supported on the lower side of the arc-shaped composite plate.

[0012] Preferably, the elastic support rod includes:

[0013] A horizontal plate, one end fixed to the middle support rod, and the other end extending horizontally;

[0014] The vertical rod is fixed at its lower end to the extension end of the horizontal plate;

[0015] A sliding sleeve is fitted and slidably connected to the upper end of the vertical rod;

[0016] A spring is provided inside the sliding sleeve, and the two ends of the spring are respectively fixed to the vertical rod and the sliding sleeve. When the spring is in its natural state, the top of the sliding sleeve is higher than the middle support rod.

[0017] Preferably, the vertical rod is a polygonal rod, and the inner wall of the sliding sleeve is adapted to and abuts against the outer wall of the vertical rod.

[0018] Preferably, the top support assembly is provided with a flexible support block on one side of the arc-shaped composite plate.

[0019] Preferably, the vertical support rod includes:

[0020] The support tube is vertically installed and its lower end is fixed to the bottom mounting component;

[0021] The drive ring is coaxially rotatably connected to the top of the support tube;

[0022] A support rod is threaded to a drive ring, and the vertical projection of the support rod is located inside a support tube. The top support assembly is located at the top of the support rod.

[0023] And a limiting rod, which is installed inside the support tube and vertically slidably connected to the support rod to prevent the support rod from rotating.

[0024] Preferably, the support tube has an annular groove, and one end of the drive ring is adapted to and rotatably connected to the annular groove.

[0025] Preferably, the bottom mounting assembly includes:

[0026] Mounting blocks, multiple of which are installed on the wall;

[0027] The horizontal plate is provided in multiple pieces, with one end fixed to the mounting block, and the vertical support rod is fixed to the horizontal plate;

[0028] And diagonal bracing, one end of which is fixed to the wall, and the other end is tilted upward and supported at the ends of multiple horizontal plates.

[0029] Preferably, the arc-shaped composite plate mounting node further includes an end pressing component disposed on the wall. The end pressing component includes a mounting base, a pressing plate connected to the mounting base, and a pressing rod threaded to the pressing plate.

Compared with the existing technology that requires the construction of a steel frame for support, the present invention can install the arc-shaped composite plate on the wall relatively quickly, reducing time, material and space costs.

[0033] 2. By setting a drive ring and a support rod, the height of the support rod and the top support assembly set on the support rod can be changed by rotating the drive ring, so as to ensure the support effect of multiple top support assemblies on arc-shaped composite plates with different arc directions and curvatures.

[0034] 3. By setting up end pressing components, the curved composite plate is supported from below by the top support components, while the pressing rod presses down on the upper side of the curved composite plate near the wall to ensure the stability of the curved composite plate and facilitate subsequent installation work.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following description is provided in conjunction with the appendix. Figure 1-3 The present invention will be further described below; the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0040] In the description of this invention, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0041] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0042] Reference Figure 1 and Figure 2This invention provides an arc-shaped composite panel installation node for assisting in the installation of an arc-shaped composite panel 1 onto a wall 2. In this embodiment, the arc-shaped composite panel installation node includes a bottom support unit, which includes a bottom mounting component 3, a vertical support rod 4, and a top support component 5. One end of the bottom mounting component 3 is mounted on the top of the wall 2, and the other end extends laterally to form a cantilever. Multiple vertical support rods 4 are provided and are spaced apart along the cantilever direction of the bottom mounting component 3. The lower end of the vertical support rod 4 is fixed to the cantilever end of the bottom mounting component 3.

[0043] Multiple top support components 5 are provided, which are vertically equal to the multiple vertical support rods 4, and the multiple top support components 5 are provided one by one at the top of the multiple vertical support rods 4 to support the lower side of the arc-shaped composite plate 1.

[0044] When the curved composite panel 1 needs to be installed at the top of the wall 2, first install the bottom mounting assembly 3 at the top of the wall 2, and then install the vertical support rod 4 and the top support assembly 5. Afterwards, when the curved composite panel 1 is installed at the top of the wall 2 by means of hoisting, the multiple top support assemblies 5 can provide support for the lowered curved composite panel 1, and the weight of the curved composite panel 1 is transferred to the wall 2. After the support is in place and the curved composite panel 1 is installed on the wall 2, it can be disassembled.

[0045] With the above installation method, it is only necessary to set the installation node of the arc-shaped composite plate at the top of the wall 2. Compared with the existing technology that requires the construction of a steel frame for support, the present invention can install the arc-shaped composite plate on the wall relatively quickly, reducing time, material and space costs.

[0046] Reference Figure 1 In one embodiment, the bottom mounting assembly 3 includes mounting blocks 31, horizontal plates 32, and diagonal bracing plates 33; multiple mounting blocks 31 are provided and are bolted to the wall 2; multiple horizontal plates 32 are provided corresponding to the mounting blocks 31; one end of the horizontal plate 32 is fixed to the mounting block 31, and the other end extends to form a cantilever end.

[0047] One end of the diagonal brace 33 is fixed to the wall 2 by the mounting block 31, and the other end is inclined upward and supported at the ends of multiple horizontal plates 32 to form a support for the cantilever ends of multiple horizontal plates 32.

[0048] Of course, in another embodiment, the mounting block 31 can also be installed by means of expansion bolts or the like pre-embedded in the wall 2.

[0049] Reference Figure 1 and Figure 2In one embodiment, the vertical support rod 4 includes a support tube 41, a drive ring 42, a support rod 43, and a limiting rod 44; the support tube 41 is a hollow tubular structure, which is vertically arranged and its lower end is fixed to the horizontal plate 32 of the bottom mounting component 3. Of course, it can be fixed to multiple horizontal plates 32 at the same time; an annular groove 411 is coaxially formed at the upper end of the support tube 41. The annular groove 411 can be a dovetail groove or a stepped groove.

[0050] One end of the drive ring 42 is adapted to and rotatably connected to the ring groove 411 to achieve connection with the support tube 41, and an internal thread is provided on the inner side of the drive ring 42, the size of which is smaller than the inner diameter of the support tube 41.

[0051] The support rod 43 is threaded to the drive ring 42, and the vertical projection of the support rod 43 is located inside the support tube 41, so that the support rod 43 can be driven to perform corresponding actions by rotating the drive ring 42. The support rod 43 has a through hole in the vertical direction. The top support assembly 5 is set at the top of the support rod 43.

[0052] The limiting rod 44 is vertically installed inside the support tube 41. Its lower end is fixed to the horizontal plate 32, and its upper end is adapted to and slidably connected to the through hole of the support rod 43. The limiting rod 44 prevents the support rod 43 from rotating with the drive ring 42, thus ensuring that the support rod 43 can only move vertically.

[0053] As one possible configuration, the through hole of the support rod 43 can be a polygonal hole, rather than a round hole.

[0054] As a second configuration, the through hole of the support rod 43 can be a round hole, but the center of the round hole does not coincide with the rotation axis of the drive ring 42.

[0055] When the vertical support rod 4 supports the arc-shaped composite plate 1 with different curvatures or directions, the support rod 43 can be moved vertically by rotating the drive ring 42, which in turn moves the top support component 5 vertically, thereby changing the support height of the top support component 5. This changes the support height of multiple top support components 5, thus ensuring the support effect on the arc-shaped composite plate 1.

[0056] Reference Figure 1 and Figure 2 The top support assembly 5 includes a central support rod 51 and multiple elastic support rods 52. The central support rod 51 is vertically arranged and its lower end is fixed to the top of the support rod 43.

[0057] Multiple elastic support rods 52 are circumferentially arranged around the central support rod 51. Each elastic support rod 52 includes a horizontal plate 521, a vertical rod 522, a sliding sleeve 523, and a spring 524. One end of the horizontal plate 521 is fixed to the central support rod 51, and the other end extends horizontally. The lower end of the vertical rod 522 is fixed to the extended end of the horizontal plate 521. The sliding sleeve 523 is fitted onto and slidably connected to the upper end of the vertical rod 522. The spring 524 is disposed inside the sliding sleeve 523, and both ends of the spring 524 are fixed to the vertical rod 522 and the sliding sleeve 523, respectively. When the spring 524 is in its natural state, the top of the sliding sleeve 523 is higher than the central support rod 51.

[0058] When the top support assembly 5 supports the arc-shaped composite plate 1, the middle support rod 51 provides rigid support to the arc-shaped composite plate 1. At the same time, under the gravity of the arc-shaped composite plate 1, the spring 524 contracts and the sliding sleeve 523 moves, ensuring that each sliding sleeve 523 can support the arc-shaped composite plate 1.

[0059] In one embodiment, flexible support blocks 53 are provided at the top of both the central support rod 51 and the sliding sleeve 523. The flexible support blocks 53 may be made of rubber to reduce damage to the surface of the arc-shaped composite plate 1 during the support process.

[0060] In one embodiment, the vertical rod 522 is a polygonal rod, and the inner wall of the sliding sleeve 523 is adapted to and abuts against the outer wall of the vertical rod 522. During the vertical movement of the sliding sleeve 523, the spring 524 is twisted due to the different force points at the top of the sliding sleeve 523, which affects its use.

[0061] Reference Figure 1 and Figure 3 According to another embodiment of the present invention, the arc-shaped composite plate mounting node further includes an end pressing component 6, which is disposed on the wall 2 and located on the end side of the arc-shaped composite plate 1 in the width direction. The end pressing component 6 applies downward pressure to the end of the arc-shaped composite plate 1 connected to the wall 2, so as to further ensure the stable installation of the arc-shaped composite plate 1 under the upward support of the top support component 5 on the other end.

[0062] Specifically, the end pressing assembly 6 includes a mounting base 61, a pressing plate 62 connected to the mounting base 61, and a pressing rod 63 threadedly connected to the pressing plate 62. The lower end of the pressing rod 63 abuts against the upper side of the arc-shaped composite plate 1 near the wall 2.

[0063] In one embodiment, the mounting base 61 includes a rotating base 611 mounted on the wall 2 and an L-shaped rod 612 rotatably connected to the rotating base 611 at one end, with a lower pressure plate 62 fixed to the upper end of the L-shaped rod 612.

[0064] While the arc-shaped composite plate 1 is supported by the top support assembly 5, the L-shaped rod 612 can be rotated so that the lower pressure plate 62 rotates to the upper side of the arc-shaped composite plate 1. Then, the lower pressure rod 63 is rotated so that the lower pressure rod 63 presses down on the arc-shaped composite plate 1.

[0065] The end of the pressure rod 63 is rounded and has a flexible layer to reduce damage.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
