Description

Technical Field

[0001] The invention relates to the technical field of prefabricated bay window construction, in particular to a temporary supporting and binding device for a prefabricated bay window. Background Art

[0002] With the continuous advancement of the construction industrialization process, the prefabricated construction model with precast concrete components as the core has been widely used. Precast bay windows are a common, standardized building component that can be produced in factories. They are installed on the main structure through integral hoisting, which can significantly improve construction efficiency and ensure component quality. During the installation process, after the precast bay window components weighing several tons are hoisted into place, a stable and reliable temporary fixing system is required to precisely maintain them in the designed position until their connection with the main structure (such as post-poured concrete, grouting sleeves, etc.) reaches sufficient strength. Therefore, designing a safe, reliable, easy-to-install, and highly adjustable temporary support and tie device is crucial to ensuring the installation accuracy and construction safety of precast bay windows.

[0003] In current construction practices, the common practice for temporary support and fixation of prefabricated bay windows is to use simple measures such as on-site temporary erection. Its mechanical structure usually utilizes existing scaffolding steel pipes, square timber, and other materials. Workers cut, weld, or tie them on-site according to actual conditions to construct one or more independent support columns. The technical principle is relatively simple, mainly installing one or two vertical support rods (commonly known as "top supports" or "jacks") below the bottom of the prefabricated bay window. By rotating the top support screw, a supporting force is applied upward to bear the weight of the bay window. Horizontally, square timber or steel pipes are used, with one end against the inside of the bay window and the other end against the indoor shear wall or floor slab. By driving wooden wedges, a horizontal tensile force is provided to prevent it from overturning or displacement.

[0004] However, this traditional support method, which relies on temporary on-site fabrication and improvised assembly, suffers from significant technical drawbacks. First, its adaptability is poor, making it incapable of accommodating prefabricated bay windows with varying base elevations. Since support rods are often cut to size on-site or employ a single top bracket with limited adjustment range, existing supports become unusable when bay windows with varying design elevations require re-fabrication, resulting in material waste and inefficient work. Second, the reliability and safety of this support system are questionable. The vertical base brace and horizontal diagonal brace are two or more independent, unsystematically connected components. They provide support or tension from only a single direction and fail to form a stable and reliable overall load-bearing system. This loose assembly, in complex construction environments, is weak against unexpected collisions and disturbances, posing a safety hazard. Finally, this method has a very low reuse rate. Due to the extensive use of welding, lashing, and wooden wedges, disassembly is difficult and damages the rods themselves. This essentially represents a one-time investment, which does not meet the requirements of green construction and cost reduction and efficiency improvement. Summary of the Invention

[0005] The purpose of the present invention is to provide a temporary support and tie device for prefabricated bay windows, which solves the problem that the original support cannot be used when encountering a bay window with a changed design elevation because the support rods are mostly cut to a fixed size on site or use a single top support with a limited adjustment range.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A temporary support and anchoring device for a prefabricated bay window comprises a bay window body, a diagonal brace embedded part fixedly connected to the interior of the bay window body, a diagonal brace adjustment rod provided inside the diagonal brace embedded part, a floor embedded reinforcement provided at the other end of the diagonal brace adjustment rod, a bottom brace adjustment rod provided at the bottom of the bay window body, a connecting plate fixedly connected to the outer wall of the bottom brace adjustment rod, and an anchoring assembly provided inside the diagonal brace adjustment rod; The tie assembly includes a second threaded rod, which is slidably connected to the inside of the diagonal support adjusting rod, and the diagonal support adjusting rod is rotatably connected to a limiting ring. One end of the limiting ring is fixedly connected to a nut, and the outer wall of the nut is fixedly connected to an extension column. The nut is threadedly connected to the outer wall of the second threaded rod, one end of the second threaded rod is fixedly connected to a connecting head, and one end of the connecting head is fixedly connected to a connecting ring. The connecting ring is buckled with the diagonal support embedded part, and an adjustment assembly is provided inside the bottom support adjusting rod, and the bottom of the bottom support adjusting rod is fixedly connected to a base.

[0007] Preferably, the adjustment component includes a threaded rod 1, which is threadedly connected to the inside of the bottom support adjustment rod. One end of the threaded rod is fixedly connected to a support plate, the top of the support plate fits with the bottom of the bay window body, and a limiting component is provided inside the bottom support adjustment rod.

[0008] Preferably, the limit assembly includes a limit plate 1, the limit plate 1 is slidably connected to the inside of the bottom support adjustment rod, a limit slot is opened inside the limit plate 1, the limit plate 1 is rotatably connected to the other end of the limit block, the limit block is fixedly connected to the inside of the bottom support adjustment rod, and the limit block is slidably connected to the inside of the limit slot.

[0009] Preferably, the outer wall of the bottom support adjustment rod is fixedly connected with a rotating fastener, and the interior of the rotating fastener is fixedly connected with a connecting steel pipe 1.

[0010] Preferably, an extension rod is slidably connected to the interior of the connecting steel pipe 1, one end of the extension rod is fixedly connected to the connecting steel pipe 2, and the interior of the extension rod is provided with adjustment slots arranged in a linear array.

[0011] Preferably, the other end of the extension rod is fixedly connected to a second limiting plate, and the second limiting plate is slidably connected to the inside of the first connecting steel pipe.

[0012] Preferably, a connecting rod is slidably connected inside the connecting steel pipe, and an adjusting column is fixedly connected to one end of the connecting rod, and the adjusting column is engaged with the adjusting groove.

[0013] Preferably, the other end of the connecting rod is rotatably connected to a rotating shaft, and the outer wall of the rotating shaft is rotatably connected to a buckle plate.

[0014] Preferably, a spring is sleeved on the outer wall of the connecting rod, one end of the spring is fixedly connected to one end of the adjusting column, and the other end of the spring is fixedly connected to the inside of the connecting steel pipe.

[0015] Working principle: When using the temporary support and tie device of the prefabricated bay window, first, when connecting, pre-embedded floor reinforcements are embedded in the building, and pre-embedded diagonal bracing parts are embedded in the bay window body. Then, the bay window body is tied to the building through the diagonal bracing adjustment rod and the pre-embedded floor reinforcements and the pre-embedded diagonal bracing parts. At the same time, the bottom of the bay window body is supported by the bottom support adjustment rod. Multiple bottom support adjustment rods are combined and limited by connecting plates. The two groups of bottom support adjustment rods are bound by connecting steel pipe 1. The connecting steel pipe 1 and the bottom support adjustment rod are installed by rotating fasteners, thereby providing temporary support and tie for the installation of the prefabricated bay window in both horizontal and vertical directions. When the support height of the bottom support adjusting rod needs to be adjusted, it is only necessary to directly rotate the threaded rod 1. The bottom of the threaded rod 1 slides and limits on the outer wall of the limit block through the limit groove in the limit plate 1, thereby preventing the threaded rod 1 from rotating together with the bottom support adjusting rod. Then, the threaded rod 1 extends from the bottom support adjusting rod through the supporting plate and abuts against the bottom of the bay window body, achieving the effect that the bottom shell does not rotate with the threaded rod when the bottom support adjusting rod is adjusted. When it is necessary to adjust the spacing between the connecting steel pipe 1 and the connecting steel pipe 2 to adapt to bay window bodies of different sizes, first, the buckle plate is pulled to rotate it with the rotating shaft as the center of the circle, and then one end of the buckle plate is pressed against the outer wall of the connecting steel pipe 1 and the adjusting column is retracted into the interior of the connecting steel pipe 1 through the connecting rod. Then, the connecting steel pipe 2 is pulled out of the connecting steel pipe 1 through the extension rod, and the extension rod is limited in the connecting steel pipe 1 by the limit plate 2. After the adjustment is in place, the buckle plate is reset, and then the adjusting column is supported by the tension of the spring, so that the adjusting column is embedded in the adjusting groove to fix the extension rod and the connecting steel pipe 1, thereby achieving the effect of facilitating the adjustment of the length of the connecting steel pipe; When it is necessary to tighten the bay window body to the building, it is only necessary to drive the nut to rotate through the extension column. The nut is rotated and limited in the diagonal bracing adjustment rod through the limiting ring, and one end of the threaded rod is connected to the diagonal bracing embedded part and the floor embedded reinforcement through the connecting ring on one side of the connecting head. Then, when the nut is turned, the threaded rod is retracted into the diagonal bracing adjustment rod for tightening. In summary, the present invention includes at least one of the following beneficial technical effects: 1. The height of the bottom support adjusting rod in the bottom support system of the present invention is adjustable, which can be applied to the installation of prefabricated bay windows with different bottom elevations. The combined system of the diagonal support and the bottom support provides temporary support and tensioning for the installation of the prefabricated bay windows in both horizontal and vertical directions, which has higher reliability, is easy to install, can be reused, has a solid structure, and is safe and reliable.

[0016] 2. The present invention rotates the threaded rod 1, and the bottom of the threaded rod 1 slides and limits on the outer wall of the limit block through the limit groove in the limit plate 1, thereby preventing the threaded rod 1 from rotating together with the bottom support adjustment rod. When the bottom support adjustment rod is adjusted, the bottom shell will not rotate along with the threaded rod, which solves the problem that when the bottom support adjustment rod is adjusted, the bottom shell is easy to rotate along with the threaded rod, resulting in the need for manual support of the bottom during adjustment, thereby improving the practicality of the temporary support and tie device of the prefabricated bay window.

[0017] 3. The present invention activates the buckle plate to rotate around the rotating shaft, and then one end of the buckle plate presses against the outer wall of the connecting steel pipe and drives the adjusting column to retract into the connecting steel pipe through the connecting rod. Then the connecting steel pipe is pulled out from the connecting steel pipe through the extension rod, thereby achieving the effect of facilitating the adjustment of the length of the connecting steel pipe. It solves the problem that the size of the connecting steel pipe is relatively fixed and inconvenient to combine when adjusting the bottom support rod of prefabricated bay windows of different sizes, and improves the convenience of temporary support and tie devices.

[0022] The outer wall of the bottom support adjustment rod 5 is fixedly connected with a connecting plate 6, which is used to connect the vertical bottom support with the diagonal tension support to form a stable triangular support structure. A tensioning assembly is provided inside the diagonal support adjustment rod 3; this assembly is used to adjust the length and tension of the diagonal support rod to achieve precise positioning and pre-tightening.

[0023] The tie assembly includes a threaded rod 26, which is used as the core force-bearing and adjustment part in the tie assembly. The threaded rod 26 is slidably connected to the inside of the diagonal support adjustment rod 3, which is used to allow the threaded rod to perform axial telescopic movement in the tube body of the diagonal support rod. The diagonal support adjustment rod 3 is internally rotatably connected to a limit ring 29, which is used as a support and positioning ring for the rotating nut, so that it can rotate in the tube but will not move axially. One end of the limit ring 29 is fixedly connected to a nut 27, which is used to indicate that the nut is fixed on the rotatable limit ring. The outer wall of the nut 27 is fixedly connected to an extension column 28, which is used as a force arm or handle to facilitate the operator to rotate the nut. The nut 27 is threadedly connected to the outer wall of the threaded rod 26, which is used to extend or retract the threaded rod 26 axially by rotating the nut, thereby adjusting the length of the diagonal support.

[0024] One end of the threaded rod 26 is fixedly connected to a connector 24, which is used as a connector at the end of the threaded rod. One end of the connector 24 is fixedly connected to a connecting ring 25, which is used as a component that is finally engaged with the embedded part. The connecting ring 25 is engaged with the diagonal brace embedded part 2 to complete the reliable connection between the diagonal brace rod and the bay window body. An adjustment component is provided inside the bottom support adjustment rod 5, which is used to accurately adjust the height of the bottom support to adapt to different installation elevations. The bottom of the bottom support adjustment rod 5 is fixedly connected to the base 14, which is used to expand the contact area with the ground, disperse the pressure, and ensure the stability of the support.

[0025] The adjustment component includes a threaded rod 12, which is used as a lifting screw rod of the height adjustment mechanism. The threaded rod 12 is threadedly connected to the bottom support adjustment rod 5 and is used to rotate the threaded rod 12 to rise or fall in the bottom support adjustment rod to achieve height adjustment. One end of the threaded rod 12 is fixedly connected to a support plate 13, which is used to provide a flat bearing surface at the top of the screw rod. The top of the support plate 13 is in contact with the bottom of the bay window body 1, which is used to evenly transfer the supporting force to the bottom of the bay window. A limit assembly is set inside the bottom support adjustment rod 5, which is used to prevent unnecessary rotation of the bottom support rod cylinder when adjusting the height.

[0026] The limiting assembly includes a limiting plate 10, which is used as a core moving component in the limiting mechanism. The limiting plate 10 is slidably connected to the bottom support adjusting rod 5 to allow the plate to move axially in the cylinder of the bottom support rod. A limiting groove 11 is provided inside the limiting plate 10 to provide a sliding guide rail for other parts. The limiting plate 10 is rotatably connected to the other end of the limiting block 9 to allow the plate to rotate relative to the limiting block. The bottom support adjusting rod 5 is fixedly connected to the limiting block 9 to provide a fixed reference point or connection point in the cylinder of the bottom support rod. The limiting block 9 is slidably connected to the limiting groove 11 to make the limiting block fixed on the cylinder slide along the groove on the limiting plate, so as to constrain movement in a specific direction.

[0027] Please see the attached Figure 4 -Attached Figure 5 The outer wall of the bottom support adjustment rod 5 is fixedly connected with a rotating fastener 7, which is used as a connecting node to connect the horizontal connecting steel pipe with the vertical bottom support adjustment rod and allow the angle between the two to be adjusted. The inside of the rotating fastener 7 is fixedly connected with a connecting steel pipe 8, which is used as the outer tube of the telescopic connecting rod and constitutes the main body of the length adjustment mechanism. The inside of the connecting steel pipe 8 is slidably connected with an extension rod 16, which is used as the inner tube of the telescopic connecting rod. The total length can be adjusted by extending or retracting it.

[0028] One end of the extension rod 16 is fixedly connected to a connecting steel pipe 2 17, which is used to constitute the other end of the telescopic connecting rod and is used to be connected to the diagonal brace adjustment rod. The extension rod 16 is provided with adjustment slots 18 arranged in a linear array inside, which are used to provide a series of discrete locking points for quick locking at different lengths. The other end of the extension rod 16 is fixedly connected to a limit plate 2 15, which is used to provide a baffle at the end of the extension rod to prevent it from completely sliding out of the connecting steel pipe 1 8. The limit plate 2 15 is slidably connected to the inside of the connecting steel pipe 1 8 to ensure that the extension rod can slide smoothly in a straight line inside the connecting steel pipe 8, and at the same time plays a guiding and limiting role.

[0029] Please see the attached Figure 5 -Attached Figure 8 The connecting steel pipe 8 is slidably connected to a connecting rod 19 inside, which is used as a transmission part to transmit the operating force from the buckle plate 22 to the adjusting column 20. One end of the connecting rod 19 is fixedly connected to the adjusting column 20, which is used as a locking pin and is responsible for inserting into the adjusting groove 18 to achieve length fixation. The adjusting column 20 is engaged with the adjusting groove 18 and is used to rigidly lock the connecting steel pipe 8 and the extension rod 16 through the engagement of the pin and the hole, thereby determining the total length of the connecting steel pipe.

[0030] The other end of the connecting rod 19 is rotatably connected to a rotating shaft 21, which is used as a fulcrum of the lever mechanism, allowing the buckle plate 22 to rotate around it. The outer wall of the rotating shaft 21 is rotatably connected to a buckle plate 22, which is used as a manually operated wrench or pull ring. By pulling it, the connecting rod 19 can be pulled. A spring 23 is provided on the outer wall of the connecting rod 19, which is used to provide a continuous thrust for the adjusting column 20 to achieve automatic reset and default locking. One end of the spring 23 is fixedly connected to one end of the adjusting column 20, which is used to directly apply the elastic force of the spring to the locking pin so that it always has a tendency to extend. The other end of the spring 23 is fixedly connected to the inside of the connecting steel pipe 8, which is used to provide a fixed support point for the spring, so that it can generate effective thrust on the adjusting column 20.

[0031] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
