Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a temporary tie-up device for short scaffolding. Background Technology

[0002] During the reverse construction of the foundation pit, to avoid excessive excavation depth for underground structure construction, a short scaffolding method can be adopted. Short scaffolding is generally composed of short steel pipes, allowing the bottom formwork of the beam to be at least approximately 0.2m above the foundation layer. Compared to conventional scaffolding (where the bottom formwork of the beam is 1-1.5m above the foundation layer), this significantly reduces the depth of each excavation, effectively improving the safety of the foundation pit project.

[0003] However, the drawback of using short scaffolding is that when excavating the next layer of underground structure, the limited internal space of the short scaffolding makes it impossible to dismantle it in advance, resulting in the scaffolding becoming suspended. To avoid the danger of the scaffolding falling, the existing fixing method is to use steel wire ropes during formwork construction, with one end tied to the scaffolding and the other end placed in the concrete to be poured. This allows it to form an integral whole with the concrete structure layer after pouring, providing a tie force to the short scaffolding. However, the tie force of this method is greatly affected by human operation, posing numerous safety hazards; moreover, the tie effect is not visually apparent, which can psychologically affect construction workers and hinder the smooth progress of underground structure construction. Summary of the Invention

[0004] To address the problems of numerous safety hazards and unintuitive tying effects in existing short-frame tie structures, the present invention provides a temporary tie device for short-frame structures, comprising: a support rod and a support frame. The top end of the support rod is fixed to the floor slab, and the bottom end of the support rod is connected to the support frame. The support frame includes multiple tie rods, one end of which is connected to the bottom end of the support rod and is horizontal in use.

[0005] A further improvement is that the top of the support rod passes through the floor slab and is fixedly connected to the floor slab by a fixing cap.

[0006] A further improvement is that the bottom end of the support rod is provided with a connecting seat, the end of the tie rod is provided with a connecting head, and the connecting head is connected to the connecting seat through a rotating shaft, and a limiting base is provided under the connecting seat.

[0007] A further improvement is that there are four tie rods, and the four tie rods are symmetrically distributed.

[0008] A further improvement is that each of the tie rods has a connector at both ends, and each connector is connected to a connector seat via a pivot.

[0009] A further improvement is that a support assembly is connected between the connecting seats on the outer sides of two adjacent tie rods.

[0010] A further improvement is made to the support assembly, which includes a connecting seat and two support rods. One end of each support rod is connected to the connecting seat at a 90° angle via the connector, and the other end of each support rod is connected to the connecting seat on the outside of the tie rod via the connector.

[0011] The beneficial effects of this invention are:

[0012] The temporary tie-up device for short scaffolding provided by this invention is detachably connected to the floor slab via support rods and is used to tie up the short scaffolding through the support frame. This not only enhances the safety and stability of the short scaffolding but also allows for direct observation of the tying effect during use, providing a better visual experience.

[0016] Figure 3 This is a structural schematic diagram of the short frame temporary tie-up device of the present invention in use. Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0018] In the description of the invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the invention and 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.

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0020] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0021] like Figures 1 to 3 As shown, the present invention provides a temporary tie-down device for short shelving units, comprising: a support rod 1 and a support frame 2. The top end of the support rod 1 is detachably fixed to the floor slab 100, and the bottom end of the support rod 1 is fixedly connected to the support frame 2. The support frame 2 includes a plurality of tie rods 21, one end of which is connected to the bottom end of the support rod 1 and is horizontal in use. Specifically, in use, the plurality of tie rods 21 are approximately horizontal, and through the tie-down action of the support rod 1, the support frame 2, composed of the plurality of tie rods 21, supports the short shelving unit 200 from the bottom.

[0022] The temporary tie-up device for short scaffolding provided by this invention is detachably connected to the floor slab via support rods and is used to tie up the short scaffolding through the support frame. This not only enhances the safety and stability of the short scaffolding but also allows for direct observation of the tying effect during use, providing a better visual experience. Furthermore, it is recyclable after use. Combined with the application of short scaffolding, it can improve the safety of foundation pit construction and the construction efficiency of underground structures.

[0023] A further improvement is that the top of the support rod 1 passes through a pre-drilled hole in the floor slab 100 and is fixedly connected to the upper surface of the floor slab 100 via a fixing cap 3. For ease of disassembly, the fixing cap 3 is threaded to the top of the support rod 1. Furthermore, to improve stability and durability, the fixing cap 3 is disc-shaped, preferably a disc with a diameter of not less than 10cm. Through the fixing cap 3, the tension force of this device on the short frame is converted into an upward supporting force on the floor slab 100, making the tensioning effect of this device more stable and reliable.

[0024] To facilitate the use of this device and allow it to pass through the pre-reserved pouring opening in the floor slab, a folding structure is adopted. Specifically, a further improvement of this technical solution is that the bottom end of the support rod 1 is provided with a connecting seat 4. The connecting seat 4 is connected to the bottom end of the support rod 1 by welding or other fixed connection methods. The connecting seat 4 provides an extended connecting arm for the installation of the connecting head 22 and the rotating shaft. The connecting arm has a through hole through which the rotating shaft passes. The end of the tie rod 21 is welded and fixed with the connecting head 22, and the connecting head 22 is rotatably installed on the rotating shaft. The connecting seat 4 is provided with a limiting base 5 to limit the rotation angle of the tie rod 21 so that it cannot be folded downwards. In use, the tie rod 21 is folded up close to the support rod. After the device is passed through the reserved hole in the floor slab, the tie rod is folded up horizontally in the direction of the short frame. Then the top of the support rod is fixedly connected to the upper surface of the floor slab by the fixing cap. The length of the support rod passing through the floor slab is adjusted by turning the fixing cap so that the support frame can support the short frame upward.

[0025] A further improvement is that there are four tie rods 21, and the four tie rods 21 are arranged in a cross-shaped symmetrical distribution.

[0026] In order to increase the support area of ​​the support frame in this solution, a further improvement of this technical solution is that each of the tie rods 21 is provided with a connector 22 at both ends, and each connector 22 is connected to a connector 4 through a rotating shaft.

[0027] A further improvement is that a support assembly is connected between the connecting seats 4 on the outer sides of two adjacent tie rods 21, so that the support frame is in a grid shape when unfolded, thereby increasing its support area.

[0028] A further improvement is made to the support assembly, which includes a connecting seat 4 and two support rods 23. One end of the two support rods 23 is connected to the connecting seat 4 at a 90° angle via the connecting head 22, and the other end of the support rods 23 is connected to the connecting seat 4 on the outside of the tie rod 21 via the connecting head 22.

[0029] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
