Description

Technical Field

[0001] This invention belongs to the field of wall tie technology, specifically relating to a scaffold wall tie device and its usage method that facilitates position adjustment. Background Technology

[0002] With the development of large-scale high-rise building systems in cities, various types of scaffolding have emerged for construction, including commonly used ground-supported scaffolding, cantilevered scaffolding, and attached lifting scaffolding. In scaffolding systems, wall ties are crucial components connecting the scaffold frame to the main building structure and transmitting tension and compression. Their installation requirements, based on calculations, typically include "two steps and three spans" or "three steps and three spans," with strict regulations on the coverage area of ​​each wall tie. Wall ties must also be installed at both ends of open scaffolding. However, in shear wall structures such as residential buildings, exterior shear walls are predominant, and the distance from the center of the connection point to the main node (the interlocking point of the upright, longitudinal horizontal bar, and transverse horizontal bar) cannot exceed 300mm. Therefore, wall ties are frequently installed on shear walls. However, traditional methods of pre-embedding wall ties have many shortcomings. Inaccurate pre-embedding can easily cause the connection point to deviate too far from the main node, and missing pre-embedding often results in wall ties failing to connect to the wall, posing a significant safety hazard. Summary of the Invention

[0003] To address the shortcomings of related technologies, this invention proposes a scaffolding wall tie device and its usage method that allows for easy position adjustment. The device can be adjusted to adapt to the main node and solve the problem of pre-embedded connection points deviating from the main node.

[0004] The technical solution adopted by this invention to solve its technical problem is:

[0005] A scaffolding wall tie device that is easy to adjust in position includes a wall tie member, wherein the wall tie member includes:

[0006] Embedded components, embedded in the wall, are used to connect the device to the wall, including an embedded plate, with embedded connectors connected to the side of the embedded plate facing the scaffold, and the embedded connectors extending out of the wall;

[0007] A wall tie assembly for connecting to a wall includes a wall tie base plate connected to a pre-embedded connector. The wall tie base plate is connected to a guide rail on the side facing the scaffold. The guide rail has multiple guide rail adjustment holes. When the wall tie base plate is rotated, the guide rail rotates accordingly to adapt to the connection point between the scaffold and the wall tie assembly.

[0008] A connecting frame assembly for connecting scaffolding includes a connecting horizontal bar, which includes a horizontal bar body and a bar base. The horizontal bar body has a vertical insertion hole, and the bar base cooperates with a guide rail slide rail. The position of the bar base and the guide rail is fixed by a bar base fixing component.

[0009] The scaffolding is connected to a vertical connecting rod on the side closest to the wall. The lower part of the vertical connecting rod is slidably inserted into a vertical insertion hole and fixed by a horizontal bar fastener.

[0010] The above-mentioned scaffolding wall tie device is easy to adjust in position.

[0011] The embedded connector is a threaded sleeve, which includes a central threaded sleeve and a side threaded sleeve. The central threaded sleeve is connected to the middle part of the embedded plate facing the scaffold, and the side threaded sleeve is connected to the side.

[0012] The wall-connecting assembly also includes a central hole in the base plate, a side hole in the base plate, and connecting bolts. The central hole in the base plate is located at a position that corresponds to the central threaded sleeve, and the side hole in the base plate is located at a position that corresponds to the side threaded sleeve. The connecting bolts are screwed onto the central threaded sleeve through the central hole in the base plate, and the connecting bolts are tightened onto the side threaded sleeves through the side hole in the base plate.

[0013] The rod base fixing component is a base screw. The rod base has a base threaded hole at a position that matches the guide rail adjustment hole. The base screw passes through the guide rail adjustment hole and is threadedly connected to the base threaded hole, thereby fixing the connecting crossbar and the guide rail together.

[0014] The scaffold is connected to a horizontal extension rod on its side, and the horizontal extension rod is connected to the upper part of the vertical connecting rod.

[0015] The aforementioned scaffolding wall tie device, which facilitates position adjustment, has an arc-shaped side hole in the base plate.

[0016] The aforementioned scaffolding wall tie device, which facilitates position adjustment, has side threaded sleeves arranged in an array around the center of the central threaded sleeve, evenly connected to the embedded plate.

[0017] The aforementioned scaffolding wall tie device, which facilitates position adjustment, has a square embedded plate with four threaded sleeves on its sides, evenly distributed in an array at the four corners of the embedded plate. The guide rail is parallel or perpendicular to one of the pairs of opposite side holes in the base plate.

[0018] The aforementioned scaffolding wall-connecting device, which facilitates position adjustment, has its guide rails closed at both ends.

[0019] The aforementioned scaffolding wall tie device, which facilitates position adjustment, has three threaded holes in the base and three corresponding base screws.

[0020] The aforementioned scaffolding wall-connecting device for easy position adjustment includes a crossbar fixing component that is a tightening screw. The side wall of the connecting crossbar has a tightening threaded hole that communicates with a vertical insertion hole. The tightening screw is threadedly connected to the tightening threaded hole for tightening.

[0021] The method of using the scaffolding wall tie device described above for easy position adjustment involves first vertically embedding the pre-embedded plate into the wall, ensuring the length of the pre-embedded connector is such that the threaded end protrudes from the wall after concrete pouring; then, attaching the wall tie base plate to the wall, and first pre-positioning by screwing the connecting bolts onto the central threaded sleeve through the central hole of the base plate; when the vertical deviation of the pre-embedded connection point from the main node is large, rotating the wall tie base plate to make its guide rail vertical, and then tightening the connecting bolts onto the side threaded sleeve through the side hole of the base plate. When the horizontal deviation of the connection point from the main node is large, rotate the wall-connecting base plate to make its guide rail horizontal. Then, tighten the connecting bolts to the side threaded sleeve through the side hole of the base plate, and tighten the connecting bolts on the middle threaded sleeve. When the pre-embedded connection point deviates from the main node at an angle, the angle can be finely adjusted through the arc-shaped side hole of the base plate. Move the connecting crossbar to slide on the guide rail. After moving it to a suitable position, screw the base screw through the guide rail adjustment hole and into the base threaded hole. Insert the lower part of the scaffolding vertical connecting rod into the vertical insertion hole and fix it with fasteners.

[0022] The purpose of the scaffolding wall tie device described in any of the above-mentioned embodiments is to connect scaffolding and walls.

[0023] The beneficial effects of this invention are:

[0024] (1) This wall connection device can adjust the position of the connecting crossbar through the guide rail to adapt to the main node and solve the problem of the pre-embedded connection point deviating from the main node.

[0025] (2) This wall connection device is equipped with a guide rail, which can be installed in a suitable position by following the direction of the guide rail. By rotating the wall connection base plate, the guide rail can be made horizontal or vertical, so that adaptive adjustments can be made according to whether the position of the pre-embedded connection point and the main node is more horizontally or vertically deviated.

[0026] (3) The side holes of the base plate are arc-shaped, which can accommodate a certain angle of adjustment, and can also make fine adjustments in the horizontal and vertical directions to further improve adaptability.

[0027] (4) The vertical connection is made by inserting the vertical connecting rod of the scaffold into the horizontal connecting rod, which is more reliable than the traditional horizontal connection. Attached Figure Description

[0038] A scaffolding wall tie device that is easy to adjust in position, such as Figure 1 As shown, it includes a wall tie 1000, which includes:

[0039] like Figure 1 and Figure 2 As shown, the embedded component 1100 is embedded in the wall 3000 and is used to connect the device to the wall. It includes an embedded plate 1101, and an embedded connector is connected to the side of the embedded plate 1101 facing the scaffold 2000. The embedded connector extends out of the wall 3000.

It includes a wall tie base plate 1201, which is connected to the pre-embedded connector. The wall tie base plate 1201 is connected to a guide rail 1202 on the side facing the scaffold 2000. The guide rail 1202 has multiple guide rail adjustment holes 12021. When the wall tie base plate 1201 is rotated, the guide rail rotates accordingly to adapt to the connection point between the scaffold 2000 and the wall tie 1000.

[0041] like Figure 1 , Figure 3 , Figure 2 As shown, the connecting frame assembly 1300 is used to connect the scaffolding 2000. It includes a connecting crossbar 1301, which includes a crossbar body 13011 and a pole base 13012. The crossbar body 13011 has a vertical insertion hole 13015. The pole base 13012 is slidably engaged with the guide rail 1202, and the position of the pole base 13012 and the guide rail 1202 is fixed by a pole base fixing component.

[0042] like Figure 1 , Figure 2 , Figure 3 As shown, the scaffold 2000 is connected to a vertical connecting rod 2002 on the side near the wall 3000. The lower part of the vertical connecting rod 2002 is slidably inserted into the vertical insertion hole 13015 and fixed by the horizontal bar fixing member.

[0043] like Figure 1 , Figure 3 , Figure 2 As shown, first, vertically embed the pre-embedded plate 1101 into the wall 3000. The length of the pre-embedded connector must ensure that the end of the pre-embedded thread is exposed after the concrete is poured. Then, pour the concrete. Next, attach the wall tie base plate 1201 to the wall 3000 and connect the wall tie base plate 1201 to the pre-embedded connector. When the vertical direction of the pre-embedded connection point deviates significantly from the main node, rotate the wall tie base plate 1201 to make the guide rail 1202 on it vertical. When the horizontal direction of the pre-embedded connection point deviates significantly from the main node... At this time, rotate the wall-connecting base plate 1201 to make the guide rail 1202 on it horizontal; move the connecting horizontal bar 1301 to slide on the guide rail 1202, and after moving to a suitable position, fix the position of the bar base 13012 and the guide rail 1202 by the bar base fixing component; insert the lower part of the scaffold vertical connecting rod 2002 into the vertical insertion hole 13015, and fix the scaffold vertical connecting rod 2002 and the connecting horizontal bar 1301 together with the horizontal bar fixing component.

[0045] like Figure 1 , Figure 2 As shown, the pre-embedded component 1100 includes a pre-embedded plate 1101 and a threaded sleeve 1102. The threaded sleeve 1102 includes a central threaded sleeve 11021 and a side threaded sleeve 11022. The central threaded sleeve 11021 is connected to the central part of the side of the pre-embedded plate 1101 facing the scaffold 2000, and the side threaded sleeve 11022 is connected to the side. It is pre-embedded in the wall 3000 and used to connect the device to the wall.

[0046] like Figure 1 , Figure 3 , Figure 4 As shown, the wall-connecting assembly 1200 includes a wall-connecting base plate 1201, a central hole 12011, a side hole 12012, a guide rail 1202, and connecting bolts 1203. The wall-connecting base plate 1201 has a central hole 12011 at a position corresponding to the central threaded sleeve 11021, and a side hole 12012 at a position corresponding to the side threaded sleeve 11022. The connecting bolts 1203 are screwed onto the central threaded sleeve 11021 through the central hole 12011, and onto the side threaded sleeve 11022 through the side hole 12012. The guide rail 1202 is connected to the side of the wall-connecting base plate 1201 facing the scaffold 2000.

The rod base 13012 has a base threaded hole 13013 at a position corresponding to the guide rail adjustment hole 12021. The base screw 13014 passes through the guide rail adjustment hole 12021 and is threadedly connected to the base threaded hole 13013, thereby fixing the connecting crossbar 1301 and the guide rail 1202 together.

[0048] like Figure 1 , Figure 2 , Figure 3 As shown, the scaffold 2000 is connected to a horizontal extension rod 2001 on its side. The upper part of the horizontal extension rod 2001 and the vertical connecting rod 2002 are connected by a right-angle coupler 2003. The lower part of the vertical connecting rod 2002 is slidably inserted into the vertical insertion hole 13015.

[0049] like Figure 4 , Figure 3 As shown, specifically, the side hole 12012 of the base plate is arc-shaped, which allows for fine-tuning of the position of the connecting bolt 1203, thus solving the problem of the connection point deviating from the main node by a certain angle due to inaccurate pre-embedding.

[0050] Instructions for use: First, vertically embed the pre-embedded plate 1101 into the wall 3000. The lengths of the central threaded sleeve 11021 and the side threaded sleeve 11022 must ensure that they are flush with the wall 3000 after the concrete is poured. A formwork can be placed over the sleeve opening to prevent concrete from clogging the sleeve. Then pour the concrete. Next, attach the wall-connecting base plate 1201 to the wall 3000. First, screw the connecting bolt 1203 onto the central threaded sleeve 11021 through the central hole 12011 of the base plate for pre-positioning. When the pre-embedded connection point deviates significantly from the main node vertically, rotate the wall-connecting base plate 1201 to make its guide rail 1202 vertical. Then, tighten the connecting bolt 1203 onto the side threaded sleeve 11022 through the side hole 12012 of the base plate. When the pre-embedded connection point deviates significantly from the main node horizontally, rotate... Tie the wall base plate 1201 to make the guide rail 1202 on it horizontal. Then, tighten the connecting bolt 1203 to the side threaded sleeve 11022 through the side hole 12012 of the base plate, and tighten the connecting bolt 1203 on the middle threaded sleeve 11021. When the pre-embedded connection point deviates from the main node at an angle, the angle can be finely adjusted through the arc-shaped side hole 12012 of the base plate. Move the connecting crossbar 1301 to slide on the guide rail 1202. After moving it to a suitable position, screw the base screw 13014 through the guide rail adjustment hole 12021 and screw it into the base threaded hole 13013. Insert the lower part of the scaffold vertical connecting rod 2002 into the vertical insertion hole 13015, and screw the tightening screw 13016 into the tightening threaded hole on the side of the tightening connecting crossbar 1301 to tighten it.

The guide rail 1202 is parallel to one of the pairs of opposite bottom plate side holes 12012.

[0053] Furthermore, the guide rail 1202 is closed at both ends to prevent the connecting component from detaching from the wall-connecting component 1200 during operation, thus avoiding the components from falling from a height.

[0054] Furthermore, an elastic washer can be installed between the connecting bolt 1203 and the wall base plate 1201 to improve the reliability of the connection.
