Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, and in particular to a universal support structure for post-pouring strips. Background Technology

[0002] The pouring of post-pouring strips is often carried out in sections according to the divided areas. The traditional formwork system for post-pouring strips uses a frame with six rows of scaffolding on both sides as the back support. Within the traffic flow of the basement roof slab, construction vehicles travel according to the planned traffic route. Therefore, the back support within the traffic route range cannot be removed and reused in other construction areas of the post-pouring strip, resulting in excessive accumulation of scaffolding materials over a long period of time. Consequently, the materials on site cannot be reused in a timely manner. Furthermore, due to the presence of scaffolding, the post-pouring strip area is not easily accessible. Utility Model Content

[0003] The purpose of this utility model is to provide an effective back-top support structure and a universal support structure for post-pouring strips that facilitates the repeated reuse of scaffolding materials.

[0004] This utility model is implemented by the following technical solution: a universal support structure for post-pouring strips, comprising a fixed base, a lifting single column, a steel pipe, a support top plate, and an adjusting nut; two or more columns with external threads are fixed on the fixed base, and the adjusting nut is screwed onto each column; a sleeve is coaxially fixed to the bottom end of the lifting single column, the sleeve is fitted onto one of the columns, and the corresponding steel pipe is fitted onto the other columns, the sleeve and the steel pipe abutting against the corresponding adjusting nut; a lifting support rod is slidably inserted into the steel pipe, and a sleeve fitted onto the telescopic end of the corresponding lifting support rod and the lifting single column is fixed on the support top plate, a locking screw is screwed onto the sleeve, and the end of the locking screw is pressed against the telescopic end of the corresponding lifting support rod and the lifting single column; the lifting single column and each steel pipe are connected by a connecting frame.

[0005] Furthermore, the connecting frame includes horizontal pull plates and diagonal pull plates. The lifting unit support column and each of the steel pipes are respectively fixed with two or more rows of horizontal pull plates, and the diagonal pull plates are fixed between the two corresponding rows of horizontal pull plates.

[0006] Furthermore, reinforcing ribs are fixed between the outer wall of the column and the fixed base, and between the outer wall of the sleeve and the supporting top plate.

[0007] Furthermore, a transverse connecting plate is connected between the telescopic rod of the adjacent lifting unit support and the lifting support rod, and between the adjacent lifting support rods. The transverse connecting plate is connected to the transverse pull plate through a support mechanism.

[0008] Furthermore, each of the telescopic rods of the lifting unit support and each of the lifting support rods is fitted with a clamp, and each clamp is vertically fixed on both sides. The two ends of the transverse connecting plate are respectively provided with adjustment elongated holes fitted on the corresponding screws, and a clamping nut that abuts against the transverse connecting plate is fitted on the screw.

[0009] Furthermore, the support mechanism includes an inclined support plate and a support sleeve sleeved on the inclined support plate. The support sleeve is rotatably connected to the transverse pull plate, and one end of the inclined support plate is rotatably connected to the transverse connecting plate. The support sleeve is provided with a limiting structure that is movably engaged with the inclined support plate.

[0010] Furthermore, the limiting structure includes a leaf spring, a pawl, and a limiting block; the support sleeve has an operating port, a hinge shaft is rotatably provided in the operating port, the pawl is fixedly sleeved on the hinge shaft, and the limiting block is fixed between the two sides of the operating port above the hinge shaft; a leaf spring that abuts against the pawl is fixed on one side of the limiting block; a plurality of arc-shaped triangular teeth are fixed along the length direction on the inclined support plate, one end of the pawl is movably engaged in the corresponding arc-shaped triangular teeth, and the other end of the pawl passes upward through the operating port and is movably engaged in the limiting block.

[0011] The advantages of this utility model are: during the construction of the post-pouring strip, scaffolding is erected in the construction area and the support structure of this embodiment is set up at intervals on both sides of the post-pouring strip; in actual use, the fixed base of the support structure is in contact with the ground, and the lifting height of the lifting single column is controlled according to the height of the support, which can be used for basement construction of different heights and has strong versatility; when the telescopic rod of the lifting single column rises, the supporting top plate and the corresponding sleeve pull each lifting rod up along the steel pipe.

[0012] When it is necessary to fine-tune the support height of the top support plate upward, the height of the lifting single support column can be fine-tuned by rotating the adjusting nut under the sleeve. Driven by the connecting frame, the height of each steel pipe is fine-tuned simultaneously. Then, rotate the adjusting nut under the steel pipe to make it abut against the corresponding steel pipe, so as to achieve precise adjustment of the installation elevation and make the top support plate in close contact with the top wooden formwork.

[0013] Once the post-cast strip construction is completed and the concrete reaches its design strength, the scaffolding can be dismantled. The support structure in this embodiment can then be used as an independent support to continue supporting both sides of the post-cast strip within the driving route area. As a result, the dismantled scaffolding materials can be reused in other construction areas, realizing material turnover and reuse, and reducing construction costs. Moreover, the spaced-out support structure increases the usable space for basement construction operations, facilitating the work of construction personnel and machinery. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0024] Example 1: As Figure 1 and Figure 2 As shown, this embodiment provides a general support structure for post-pouring strips, which includes a fixed base 1, a lifting single column 4, a steel pipe 6, a supporting top plate 10, and an adjusting nut 3.

[0025] Three columns 2 arranged in a triangular pattern are vertically fixed on the fixed base 1. Reinforcing ribs 12 are fixed between the outer wall of the columns 2 and the fixed base 1 to strengthen the support. The columns 2 are provided with external threads, and each column 2 is fitted with an adjusting nut 3. The bottom end of the lifting unit support 4 is coaxially fixed with a sleeve 5. In this embodiment, the lifting unit support 4 is a hydraulic support. The sleeve 5 is fitted on one of the columns 2, and the other columns 2 are fitted with corresponding steel pipes 6. The sleeve 5 and the steel pipes 6 abut against the corresponding adjusting nuts 3. The adjusting nuts 3 provide effective support for the sleeve 5 and the steel pipes 6.

[0026] A lifting support rod 7 is slidably inserted inside the steel pipe 6. A sleeve 8 is fixed on the top support plate 10 and sleeved on the telescopic ends of the corresponding lifting support rod 7 and lifting single column 4. A reinforcing rib plate 12 is fixed between the outer wall of the sleeve 8 and the top support plate 10 to strengthen the support. The top ends of the lifting support rod 7 and the telescopic rod of the lifting single column 4 are in contact with the top support plate 10. A locking screw 9 is screwed through the sleeve 8. The end of the locking screw 9 is pressed against the telescopic ends of the corresponding lifting support rod 7 and lifting single column 4 to ensure that the lifting single column 4 can drive each lifting support rod 7 to move up and down when it is raised and lowered. The top support plate 10 can be easily disassembled and assembled by tightening and loosening the locking screw 9.

[0027] In this embodiment, as a back-top support, the fixed base 1 contacts the ground during actual use. The lifting height of the lifting single column 4 is controlled according to the support height, which can be used for basement construction at different heights and has strong versatility. When the telescopic rod of the lifting single column 4 rises, the supporting top plate 10 and the corresponding sleeve 8 pull each lifting support rod 7 to rise along the steel pipe 6.

[0028] The main body of the lifting single support column 4 and each steel pipe 6 are connected by a connecting frame 11, which helps to improve the overall load-bearing capacity. When it is necessary to make a slight upward adjustment to the support height of the support top plate 10, the height of the lifting single support column 4 can be finely adjusted by rotating the adjusting nut 3 below the sleeve 5. Under the drive of the connecting frame 11, the height of each steel pipe 6 is finely adjusted simultaneously. Then, the adjusting nut 3 below the steel pipe 6 is rotated to make it abut against the corresponding steel pipe 6.

[0029] The connecting frame 11 includes a horizontal tie plate 11.1 and an oblique tie plate 11.2. The lifting unit support column 4 and each steel pipe 6 are respectively fixed with two rows of horizontal tie plates 11.1. The two corresponding rows of horizontal tie plates 11.1 are fixed with oblique tie plates 11.2 by connecting bolts 11.3, which facilitates disassembly and assembly.

[0030] During the pouring of the post-pouring strip, scaffolding is erected in the construction area, and the support structure of this embodiment is set up at intervals on both sides of the post-pouring strip. After the post-pouring strip construction is completed and the concrete reaches the design strength, the scaffolding can be dismantled. The support structure of this embodiment continues to support both sides of the post-pouring strip within the driving route area as an independent support. Thus, the dismantled scaffolding materials can be reused in other construction areas, realizing the turnover and reuse of materials and reducing construction costs. Moreover, the spaced support structure increases the operating space for basement construction, which is convenient for construction personnel and construction machinery.

[0031] Example 2: Figures 3 to 7 As shown, based on Embodiment 1, this embodiment also includes a transverse connecting plate 13, a support mechanism 14, and a clamp 15.

[0032] A transverse connecting plate 13 is connected between the telescopic rods and lifting rods 7 of adjacent lifting single support columns 4 and between adjacent lifting rods 7. The transverse connecting plate 13 is connected to the transverse tie plate 11.1 through the support mechanism 14, which plays a stabilizing role for the telescopic rods of the lifting single support column 4 and each lifting rod 7, and further improves the overall support strength.

[0033] The telescopic rods of the lifting single support column 4 and each lifting support rod 7 are fitted with clamps 15 for easy assembly and disassembly; each clamp 15 is vertically fixed on both sides with screws 16; the two ends of the transverse connecting plate 13 are respectively provided with adjusting elongated holes 13.1 fitted on the corresponding screws 16; the screws 16 are fitted with clamping nuts 17 that abut against the transverse connecting plate 13, thereby pressing the transverse connecting plate 13 tightly onto the clamps 15.

[0034] The support mechanism 14 includes an inclined support plate 14.1 and a support sleeve 14.2 sleeved on the inclined support plate 14.1. The support sleeve 14.2 is rotatably connected to the transverse pull plate 11.1. In the prior art, the rotation of the support sleeve 14.2 can be achieved by passing a rotating shaft through the transverse pull plate 11.1 and fixing one end of the shaft to the support sleeve 14.2. One end of the inclined support plate 14.1 is rotatably connected to the transverse connecting plate 13. The support sleeve 14.2 is provided with a limiting structure 14.3 that is movably engaged with the inclined support plate 14.1. During the process of the inclined support plate 14.1 rising and falling with the transverse connecting plate 13, the inclined support plate 14.1 moves along the support sleeve 14.2, while simultaneously driving the support sleeve 14.2 to swing.

[0035] The limiting structure 14.3 includes a leaf spring 14.31, a pawl 14.32, and a limiting block 14.33. An operating port 14.21 is provided on the support sleeve 14.2. A hinge shaft 14.34 is rotatably mounted within the operating port 14.21. The hinge shaft 14.34 is positioned along the width direction of the inclined support plate 14.1. A pawl 14.32 is fixedly fitted onto the hinge shaft 14.34, and the pawl 14.32 can swing with the hinge shaft 14.34 when subjected to force. A limiting block 14.33 is fixed between the two sides of the operating port 14.21 above the hinge shaft 14.34. A leaf spring 14.31, which abuts against the pawl 14.32, is fixed on one side of the limiting block 14.33. Several arc-shaped triangular teeth 14.11 are fixed along the length direction on the inclined support plate 14.1. One end of the pawl 14.32 is movably engaged within the corresponding arc-shaped triangular tooth 14.11, while the other end of the pawl 14.32 passes upward through the operating port 14.21 and is movably engaged with the limiting block 14.33. Under the action of the leaf spring 14.31, one end of the pawl 14.32 presses against the arc surface of the arc-shaped triangular tooth 14.11. During the upward movement of the inclined support plate 14.1, each arc-shaped triangular tooth 14.11 passes through the pawl 14.32 in sequence. However, when the inclined support plate 14.1 moves downward, one end of the pawl 14.32 will engage between two adjacent arc-shaped triangular teeth 14.11, serving as a limiting support function. According to operational needs, when it is necessary to adjust the inclined support plate 14.1 downward, the other end of the pawl 14.32 is moved in advance, such as... Figure 7 As shown, the pawl 14.32 removes the restriction on the arc-shaped triangular tooth 14.11, making it easier for the inclined support plate 14.1 to move downward.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
