Description

Technical Field

[0001] The utility model relates to the technical field of scaffolding, and more specifically, to a scaffolding connecting device for civil construction. Background Art

[0002] Scaffolding plays an important role in civil engineering projects. Proper scaffolding installation can ensure accuracy and smoothness during construction. The connection structure of scaffolding joints can ensure the stability of the scaffolding under various construction conditions.

[0003] The patent with announcement number CN213806542U discloses a scaffold connection device for civil engineering construction, which realizes the rapid construction of scaffolding by matching sleeve 1 with fastening screw sleeve 1, and sleeve 2 with fastening screw sleeve 2. However, in the above-mentioned scaffold connection device, the connection block connecting each metal pipe is connected to the main block by a pressure block and bolts. When the scaffold is subjected to a large force, the plate-shaped pressure block connected by the bolt may not be able to withstand the excessive force, so there is a possibility that the scaffold connection will loosen or even fall, and its stability is poor. At the same time, scaffolding built at a high place needs to be fixed with diagonal rods to increase the stability of the whole frame. However, the above-mentioned scaffold connection device does not have a connection structure for installing diagonal rods, so diagonal rods cannot be installed, and its scope of application is limited. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings, the utility model aims to provide a scaffold connecting device for civil construction.

[0005] A scaffold connection device for civil construction includes a main body block, wherein the main body block is provided with transverse through-holes, longitudinal through-holes and vertical through-holes;

[0006] The horizontal rod, the longitudinal rod and the vertical rod are respectively passed through the horizontal through-hole, the longitudinal through-hole and the vertical through-hole and then positioned by fasteners; the fasteners are threadedly connected to the ends of the horizontal rod, the longitudinal rod and the vertical rod.

[0007] Furthermore, the transverse perforations and longitudinal perforations are respectively arranged horizontally, and the two are staggered and perpendicular; the vertical perforations are arranged vertically, and do not intersect with the transverse perforations and longitudinal perforations.

[0008] Furthermore, both ends of the horizontal rod, the longitudinal rod and the vertical rod are respectively provided with threads.

[0009] Furthermore, the fastener includes a ring and a rotating rod fixed to the outer wall of the ring; the ring is provided with an internal thread, which is adapted to the threads of the ends of the cross bar, longitudinal bar and vertical bar.

[0010] Furthermore, the rotating rod is two rods symmetrically arranged on the outer wall of the ring. By turning the rotating rod, the fastener can be rotated so that it rotates at the end of the horizontal rod, vertical rod or vertical rod until it reaches a suitable position.

[0011] Furthermore, it also includes a rotating connecting member;

[0012] The rotating connecting member is rotatably connected to the threaded position of the end of the horizontal rod, vertical rod or vertical rod;

[0013] The rotating connecting member comprises a rotating body, and an oblique through hole for connecting an oblique rod is provided on the rotating body.

[0014] Furthermore, after the oblique rod passes through the oblique through-hole, its end is limited by a fastener.

[0015] Furthermore, the inner walls of the transverse perforations, longitudinal perforations, vertical perforations, and oblique perforations are not provided with threads.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] During the scaffolding construction process, the connections between the horizontal bars, vertical bars, and vertical bars are connected using local construction scaffolding connection devices. The horizontal bars pass through the horizontal perforations, the vertical bars pass through the longitudinal perforations, and the vertical bars pass through the vertical perforations. After passing through the main block, the ends of each bar are limited and connected using fasteners, thus forming a stable connection between the horizontal bars, vertical bars, and vertical bars, preventing the connection from falling and providing excellent stability. In addition, at the end of the horizontal bar, vertical bar, or vertical bar extending out of the main block, the diagonal bar can be installed by rotating the connecting piece, providing flexible installation with adjustable angles for the installation of the diagonal bar in the scaffolding, strong adaptability, and a wide range of applications.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] like Figures 1-4 As shown, this embodiment provides a scaffold connection device for civil engineering, comprising a main body block 1. The main body block 1 is provided with transverse through-holes 11, longitudinal through-holes 12, and vertical through-holes 13. The transverse bars 2, longitudinal bars 3, and vertical bars 4 are inserted through the corresponding transverse through-holes 11, longitudinal through-holes 12, and vertical through-holes 13, respectively, and then positioned by fasteners 5. The fasteners 5 are threadedly connected to the ends of the transverse bars 2, longitudinal bars 3, and vertical bars 4, thereby securing the ends of the transverse bars 2, longitudinal bars 3, and vertical bars 4.

[0029] In this embodiment, Figure 1 and Figure 2 As shown, the main block 1 is rectangular with rounded vertical edges. Transverse perforations 11, longitudinal perforations 12, and vertical perforations 13 are provided on the main block 1. The transverse perforations 11 and longitudinal perforations 12 are arranged horizontally, located on different horizontal planes and staggered perpendicularly. The vertical perforations 13 are arranged vertically on the main block 1 and do not intersect with the transverse perforations 11 and longitudinal perforations 12. This design ensures that the transverse rods 2, longitudinal rods 3, and vertical rods 4 do not interfere with each other when inserted into the main block 1. Each rod can be independently inserted into its corresponding hole and then fixed in place using fasteners 5.

[0030] More specifically, both ends of the horizontal rod 2 , the vertical rod 3 and the vertical rod 4 are respectively provided with threads, which can be threadedly connected with the fastener 5 .

[0031] Specifically, if Figure 1 and Figure 3 As shown, fastener 5 comprises a collar 51 and a rotating rod 52 fixed to the outer wall of collar 51. Collar 51 is internally threaded, matching the threads on the ends of crossbar 2, longitudinal rod 3, and vertical rod 4. The rotating rods 52 are two rods symmetrically arranged on the outer wall of collar 51. By turning the rotating rods 52, fastener 5 can be rotated, rotating it around the ends of crossbar 2, longitudinal rod 3, or vertical rod 4 until it reaches a desired position, for example, until it abuts the main body.

[0032] During the erection of the scaffold, at the intersection of the horizontal bars 2, the vertical bars 3 and the vertical bars 4, the present connection device is used to insert the horizontal bars 2, the vertical bars 3 and the vertical bars 4 into the corresponding through-holes in the main block 1 of the present device respectively, and then the fasteners 5 are screwed on the ends of the horizontal bars 2, the vertical bars 3 and the vertical bars 4 extending out of the main block 1, and the fasteners 5 are tightened so that they abut against the outer wall of the main block, thereby achieving a stable and fixed connection of the horizontal bars 2, the vertical bars 3 and the vertical bars 4 at this connection point.

[0033] In this embodiment, Figure 4-Figure 7 As shown, to stably secure the diagonal rod 6, the scaffolding connection device further includes a rotating connector 7. The rotating connector 7 is rotatably connected to the threaded ends of the horizontal rod 2, vertical rod 3, or vertical rod 4. The rotating connector 7 includes a rotating body 71 having a sleeve hole 711, which is adapted to be sleeved over the threaded ends of the horizontal rod 2, vertical rod 3, or vertical rod 4. The rotating body 71 is provided with an oblique through-hole 72 for connecting the diagonal rod 6. After the diagonal rod 6 passes through the oblique through-hole 72, its end is secured by a fastener 5.

[0034] by Figure 5 For example, set the crossbar 2 to the X-axis direction, the longitudinal bar 3 to the Y-axis direction, and the vertical bar 4 to the Z-axis direction. The rotating connector 7 can be installed on the crossbar 2 so that it can be installed together with the rotating connector at the end of another crossbar that is offset above or below the horizontal plane of the crossbar 2 to install the diagonal rod of the YZ plane. Since two points can determine a straight line, the rotating connectors at the ends of the two crossbars can be used to firmly fix the diagonal rod. After the rotating connectors at the ends of the two crossbars have adjusted their angles and positions respectively, fasteners 5 are used to tighten the ends of the rotating connectors. At this time, the two ends of the rotating connector are respectively abutted against each other with fasteners, which can achieve the fixation of the rotating connector at this position and angle.

[0035] Similarly, if Figure 6As shown, when the connecting rotatable member 7 is installed on the longitudinal rod 3, it is coordinated with the rotating connector of another longitudinal rod offset above or below the horizontal plane of the longitudinal rod 3 to install the diagonal rod in the XZ plane. After the rotating connectors at the ends of the two longitudinal rods are adjusted to the desired angle and position, fasteners are used to tighten the external ends of the rotating connectors. At this point, the fasteners abut both ends of the rotating connectors, securing the rotating connectors at the desired position and angle.

[0036] Similarly, if Figure 7 As shown, when the connecting rotatable member 7 is installed on the vertical pole 4, it cooperates with the rotating connecting member of another vertical pole offset to the left or right of the vertical plane where the vertical pole 4 is located to install the diagonal rod in the XY plane. After the rotating connecting members at the ends of the two vertical poles are adjusted to the desired angle and position, fasteners are used to tighten the external ends of the rotating connecting members. At this point, the fasteners abut against each other at both ends of the rotating connecting member, thus securing the rotating connecting member at the desired position and angle.

[0037] It is worth noting that the inner walls of the transverse through-hole 11 , the longitudinal through-hole 12 , the vertical through-hole 13 , the oblique through-hole 72 , and the sleeve hole 711 are not provided with threads, so that they can be directly inserted into the corresponding structure more conveniently.

[0038] The scaffolding connection device for civil engineering provided in this embodiment is used to connect the crossbars 2, longitudinal bars 3, and vertical bars 4 at their joints during the scaffolding construction process. The crossbars 2 pass through the transverse through-holes 11, the longitudinal bars 3 pass through the longitudinal through-holes 12, and the vertical bars 4 pass through the vertical through-holes 13. After passing through the main block 1, the ends of each bar are connected by fasteners 5 for position limiting, thereby forming a stable connection between the crossbars 2, longitudinal bars 3, and vertical bars 4. The connection will not fall off, and the stability is excellent. At the end of the crossbars 2, longitudinal bars 3, or vertical bars 4 extending out of the main block 1, the diagonal bars 6 can be installed by rotating the connector 7, providing a flexible installation method with adjustable angles for the installation of diagonal bars in the scaffolding, with strong adaptability and a wide range of applications.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
