Description

Technical Field

[0001] This utility model relates to the field of building assembly technology, specifically a temporary fixing device for prefabricated columns in building assembly. Background Technology

[0002] In the construction of prefabricated structures for buildings, precast columns need to be precisely installed in the designed positions. Due to the large self-weight of precast columns, their susceptibility to external load disturbances during installation, and the need to maintain stability after verticality adjustment until the joint connection strength meets the standards, temporary fixing devices must be used to achieve positioning and stability during installation to ensure construction accuracy and safety.

[0003] Existing temporary fixing devices typically connect to precast columns and foundations via adjustable support structures, enabling fine-tuning of the precast column's verticality and providing a certain load-bearing capacity to temporarily support the column's self-weight and construction loads, creating stable conditions for node construction. However, existing devices suffer from insufficient support stability and weak resistance to lateral displacement, making them prone to swaying under sudden loads such as strong winds, and failing to ensure the precast column's verticality remains within allowable deviation range. Therefore, we provide a temporary fixing device for precast columns in building assembly to address these issues. Utility Model Content

[0004] 1) Technical problems to be solved

[0005] This utility model proposes a temporary fixing device for prefabricated columns in building construction. Through the cooperation of components such as sliding cavity, second connecting plate, second through hole, second threaded hole, second threaded rod, second rotating disk, sliding plate, and ground nail, it solves the problems of insufficient support stability and weak anti-lateral displacement ability of existing devices. These devices are prone to shaking when encountering sudden loads such as strong winds, and it is difficult to ensure that the verticality of the prefabricated column is kept within the allowable deviation range.

[0006] (ii) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a temporary fixing device for prefabricated columns in building assembly, including a support mechanism, with two sets of mutually symmetrical anti-slip mechanisms arranged below the support mechanism. The anti-slip mechanism includes a sliding frame, a sliding cavity is formed on the lower surface of the sliding frame, a second connecting plate is fixedly connected to the bottom of the inner sidewall of the sliding cavity, a plurality of second through holes are formed on the upper surface of the second connecting plate, and two sets of mutually symmetrical second threaded holes are formed on the inner top wall of the sliding cavity. A second threaded rod is threadedly connected to the inner sidewall of each of the two sets of second threaded holes.

[0008] The top ends of both sets of second threaded rods are fixedly connected to a second rotating disk, and the bottom ends of both sets of second threaded rods are fixedly connected to a sliding plate. The side wall of the sliding plate is slidably connected to the inner side wall of the sliding cavity. The lower surface of the sliding plate is fixedly connected to a plurality of gripping nails, and the conical tips of the plurality of gripping nails pass through a plurality of second through holes.

[0009] Furthermore, the support mechanism includes a U-shaped frame and a first connecting plate. The right side of the U-shaped frame has two sets of symmetrical first through holes, and the left side of the first connecting plate is fixedly connected to two sets of symmetrical lead screws.

[0010] Furthermore, the left ends of both sets of lead screws pass through the first through hole and are threaded with nuts. The U-shaped frame and the first connecting plate are fixed together by the lead screws and nuts to form an annular frame.

[0011] Furthermore, the outer surface of the annular frame is provided with two sets of mutually symmetrical first threaded holes, and the inner sidewalls of the two sets of first threaded holes are threaded with first threaded rods.

[0012] Furthermore, each of the two sets of first threaded rods has a first rotating disk fixedly connected to its far-away ends, and a top holding disk rotatably connected to its close-away ends.

[0013] Furthermore, two sets of mutually symmetrical first hinge blocks are fixedly installed on the lower part of the outer surface of the annular frame, and the annular frame is hinged to two sets of mutually symmetrical hinge rods through the two sets of mutually symmetrical first hinge blocks.

[0014] Furthermore, a second hinge block is installed at one end of each of the two sets of hinge rods away from the first hinge block, and the two sets of hinge rods are respectively hinged to the upper surface of the sliding frame inside the two sets of anti-slip mechanisms through the two sets of second hinge blocks.

[0015] (iii) Beneficial effects:

[0016] Compared with existing technologies, this temporary fixing device for prefabricated columns in building construction has the following advantages:

[0017] I. This temporary fixing device for prefabricated columns in building construction, through a design combining anti-slip mechanism threaded transmission and mechanical anchoring, constructs a stable ground connection system. When the second rotating disk is rotated, the spiral motion of the second threaded rod along the second threaded hole is converted into the linear downward movement of the sliding plate along the inner wall of the sliding cavity. This causes multiple gripping nails at the bottom of the sliding plate to pass through the second perforation on the second connecting plate. Their conical tips can quickly penetrate the ground soil, concrete base layer, or gravel cushion layer, forming a multi-point evenly distributed anchoring structure. This design not only increases the contact area and friction between the device and the ground, but the conical structure of the gripping nails can also generate strong pull-out force, effectively resisting the horizontal thrust and vertical pull-out force generated by strong winds and prefabricated column swaying, solving the problem of easy swaying in traditional devices. In addition, the sliding cooperation between the sliding plate and the sliding cavity ensures the smoothness of the adjustment process, avoids adjustment jamming, and further improves operating efficiency.

[0018] II. This temporary fixing device for precast columns in building construction uses a screw rod and nut to fix a U-shaped frame and a first connecting plate into a fixed-size annular frame. Its innovation lies in the adjustment and clamping structure formed by the first threaded rod, the first rotating disk, and the top holding disk. The rotation of the first rotating disk drives the first threaded rod to extend and retract along the first threaded hole, allowing the top holding disk to closely fit the surface of precast columns of different diameters. This achieves stable clamping of precast columns of various sizes without the need to replace the annular frame for different sizes of precast columns, reducing equipment replacement costs and operational complexity. At the same time, the coordinated clamping of multiple sets of top holding disks can achieve fine adjustment of the verticality of the precast column, with adjustment accuracy controllable within the millimeter range. This solves the problems of poor adaptability and insufficient positioning accuracy of traditional devices for precast columns of different sizes, ensuring that the installation error of the precast column is strictly controlled within the design allowable deviation.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1-5 As shown, this utility model provides a technical solution: a temporary fixing device for prefabricated columns in building assembly, including a support mechanism 1. Below the support mechanism 1, two sets of mutually symmetrical anti-slip mechanisms 2 are arranged. Each anti-slip mechanism 2 includes a sliding frame 201. A sliding cavity 202 is formed on the lower surface of the sliding frame 201. A second connecting plate 203 is fixedly connected to the bottom of the inner wall of the sliding cavity 202. Multiple second through holes 204 are formed on the upper surface of the second connecting plate 203. Two sets of mutually symmetrical anti-slip mechanisms 2 are formed on the inner top wall of the sliding cavity 202. Symmetrical second threaded holes 205, the inner walls of both sets of second threaded holes 205 are threaded with second threaded rods 206, the top ends of both sets of second threaded rods 206 are fixedly connected with second rotating disks 207, the bottom ends of both sets of second threaded rods 206 are fixedly connected with sliding plates 208, the side walls of sliding plates 208 are slidably connected with the inner walls of sliding cavities 202, and the lower surface of sliding plates 208 is fixedly connected with multiple gripping nails 209, the conical tips of the multiple gripping nails 209 respectively penetrate multiple second through holes 204.

[0028] The pointed ends of the multiple gripping spikes 209 here all face downwards, and the preferred material for the gripping spikes 209 here is high-strength hot-rolled steel.

[0029] By combining the anti-slip mechanism 2 with threaded transmission and mechanical anchoring, a stable ground connection system is constructed. When the second rotating disk 207 is rotated, the spiral motion of the second threaded rod 206 along the second threaded hole 205 is converted into the linear downward movement of the sliding plate 208 along the inner wall of the sliding cavity 202. This causes multiple gripping nails 209 at the bottom of the sliding plate 208 to pass through the second perforation 204 on the second connecting plate 203. Their conical tips can quickly penetrate the ground soil, concrete base layer, or gravel cushion layer, forming a multi-point evenly distributed anchoring structure. This design not only increases the contact area and friction between the device and the ground, but the conical structure of the gripping nails 209 can also generate strong pull-out force, which can effectively resist the horizontal thrust and vertical pull-out force generated by strong winds, precast column swaying, etc., solving the problem of easy swaying of traditional devices. In addition, the sliding cooperation between the sliding plate 208 and the sliding cavity 202 ensures the smoothness of the adjustment process, avoids adjustment jamming, and further improves the operating efficiency.

[0030] The support mechanism 1 includes a U-shaped frame 101 and a first connecting plate 103. Two sets of symmetrical first through holes 102 are opened on the right side of the U-shaped frame 101. Two sets of symmetrical lead screws 104 are fixedly connected to the left side of the first connecting plate 103. The left ends of both sets of lead screws 104 pass through the first through holes 102 and are threaded with nuts 105. The U-shaped frame 101 and the first connecting plate 103 form an annular frame through the fixing of the lead screws 104 and nuts 105. Two sets of symmetrical first threaded holes 106 are opened on the outer surface of the annular frame. First threaded rods 107 are threadedly connected to the inner walls of both sets of first threaded holes 106. The ends of the first threaded rods 107 that are far apart from each other are fixedly connected to the first rotating disks 108. The ends of the two sets of first threaded rods 107 that are close to each other are rotatably connected to the top holding disks 109. Two sets of mutually symmetrical first hinge blocks 110 are fixedly installed on the lower part of the outer surface of the annular frame. The annular frame is hinged to two sets of mutually symmetrical hinge rods 111 through the two sets of mutually symmetrical first hinge blocks 110. The ends of the two sets of hinge rods 111 that are far away from the first hinge blocks 110 are installed with second hinge blocks 112. The two sets of hinge rods 111 are respectively hinged to the upper surface of the sliding frame 201 inside the two sets of anti-slip mechanisms 2 through the two sets of second hinge blocks 112.

[0031] The U-shaped frame 101 and the first connecting plate 103 are fixed together by the cooperation of the lead screw 104 and the nut 105 to form a ring frame of a fixed size. Its innovation lies in the adjustment and clamping structure formed by the first threaded rod 107, the first rotating disk 108 and the top holding disk 109. The rotation of the first rotating disk 108 drives the first threaded rod 107 to extend and retract along the first threaded hole 106, so that the top holding disk 109 can closely fit the surface of the precast column of different diameters, thereby achieving stable clamping of precast columns of various sizes. There is no need to replace the ring frame for precast columns of different sizes, reducing equipment replacement costs and operational complexity. At the same time, the coordinated clamping of multiple sets of top holding disks 109 can achieve fine adjustment of the verticality of the precast column. The adjustment accuracy can be controlled within the millimeter range, which solves the problems of poor adaptability and insufficient positioning accuracy of traditional devices for precast columns of different sizes, and ensures that the installation error of the precast column is strictly controlled within the design allowable deviation.

[0032] Working principle: First, the U-shaped frame 101 and the first connecting plate 103 are connected by a screw 104 through the first through hole 102 and screwed into a nut 105 to form a ring frame of a fixed size. The ring frame is then fitted onto the outside of the precast column. Next, the first rotating disk 108 is rotated, causing the first threaded rod 107 to advance along the first threaded hole 106, driving the top holding disk 109 to tightly adhere to the surface of the precast column. The extension and retraction of the first threaded rod 107 adapts to precast columns of different sizes. The verticality of the precast column is adjusted through the coordinated clamping action of multiple sets of top holding disks 109 until the design requirements are met. After the support mechanism is positioned, the anti-slip mechanism 2 is placed in a preset position on the ground through the cooperation of the first hinge block 110, the hinge rod 111, and the second hinge block 112. The second rotating disk 108 is then rotated. The rotating disc 207 moves the second threaded rod 206 downward along the second threaded hole 205, pushing the sliding plate 208 down the inner wall of the sliding cavity 202. At this time, the gripping nail 209 at the bottom of the sliding plate 208 passes through the second through hole 204 on the second connecting plate 203, and the conical tip gradually penetrates into the ground soil or base layer, forming a multi-point anchoring structure. By increasing the friction and pull-out resistance, the device is prevented from sliding or tipping over. When the connection strength of the precast column node reaches the standard, the second rotating disc 207 is rotated in the opposite direction, so that the gripping nail 209 is retracted into the sliding cavity 202. Then, the nut 105 is loosened to separate the U-shaped frame 101 from the first connecting plate 103, and the support mechanism 1 is removed, completing the device disassembly. Each component can be disassembled and stored for easy transfer to the next construction node for reuse.
