Description

Technical Field

[0001] The present application relates to the field of foundation engineering technology, and more specifically, to a slope support formwork support frame and a construction method thereof. Background Art

[0002] Slope support refers to the support, reinforcement and protection measures taken on the slope to ensure the safety of the slope and its environment. Commonly used support structure types include: gravity retaining wall, buttress retaining wall, cantilever support, plate rib or lattice anchor retaining wall support, pile anchor retaining wall support, anchor spraying support, and slope method. Slope support is widely used in engineering construction, but it also has some disadvantages:

[0003] There is a certain complexity in construction. The installation and removal of slope support formwork requires professional skills. For unfamiliar construction workers, it is easy to make mistakes. The complex steps in the construction process may extend the construction period and affect the overall progress of the project. There is a disadvantage of high investment in material costs. The use of high-strength materials and formwork may lead to increased initial investment, especially in large-scale projects. The formwork may be worn during use and requires regular maintenance and replacement, which increases long-term operating costs.

[0004] As for its supporting performance, there are two situations: uneven force and design limitations. When the slope support is subjected to uneven force, it may cause deformation or tilt of the supporting structure, affecting its stability. At the same time, due to design limitations, under certain special geological conditions, traditional support solutions may not ensure sufficient safety. If the support is improper, it may cause the collapse of the entire slope, posing a threat to construction personnel and equipment. In addition, traditional support methods often lack effective monitoring methods and cannot detect potential risks in a timely manner, posing a potential threat to the project.

[0005] In response to the above problems, the utility model patent with announcement number CN207608909U discloses a lattice beam formwork fixer and a lattice beam formwork support structure for slope support. The structure replaces the original wooden square fixing method by inserting the fixer outside the two side forms and clamping the side forms. Although this design reduces the waste of wooden squares, its fixing and stabilizing effect is not ideal, especially when facing complex terrain and large construction loads.

[0006] The invention patent with publication number CN110355733A discloses an adjustable inclined plane support device and method, which is connected and fixed to the base through a vertical support and a lifting mechanism, connected to the vertical support and the lifting mechanism through the inclined plane support pin, and the inclined plane support is pushed to rotate around the vertical support to adjust the inclination angle of the support member during the lifting process of the lifting mechanism. Although this design provides a certain degree of adjustability, its structure is complex, the operation is inconvenient, and there may be stability problems in actual application.

[0007] Therefore, how to provide a slope support formwork support frame with a simpler structure and higher stability to adapt to different construction environments, ensure the safety and reliability of the support frame when bearing heavy loads, and reduce construction risks has become a technical problem that needs to be solved. Summary of the invention

[0008] In view of this, the present application provides a slope support formwork support frame and a construction method thereof, which adopts multi-point support for the slope support formwork and does not need to set up multiple connecting support frame mechanisms, thus saving time and effort in operation and improving installation efficiency and safety.

[0009] In a first aspect, the present application provides a slope support formwork support frame, comprising a support column and at least two support structures arranged along the height direction of the support column;

[0010] The support structure includes a threaded rod, a mounting seat arranged at one end of the threaded rod, and a triangular support frame fixed to a side of the mounting seat away from the threaded rod; the mounting seat is rotatably connected to the threaded rod, and the side of the triangular support frame away from the threaded rod is provided with at least two pressing plates for supporting the slope support template body, and at least two of the pressing plates are equidistantly distributed along the length direction of the triangular support frame;

[0011] A guide seat corresponding to the triangular support frame is vertically fixedly connected to one side of the support column close to the triangular support frame, and each guide seat is located under the corresponding triangular support frame. A sliding groove is provided on the top of the guide seat; a sliding block slidably connected to the sliding groove is provided at the bottom of the mounting seat.

[0012] In one possible implementation, an inclined support mechanism is fixed at the bottom of the support column, and the inclined support mechanism includes a support base, a first inclined support rod fixedly connected between the support column and the support base, and two second inclined support rods fixed on both sides of the support base; wherein the two second inclined support rods are parallel to each other and are connected to the support column via a transverse connecting member fixed on the support column.

[0013] In one possible implementation manner, an inclination angle between the two second inclined support rods and the support base is greater than an inclination angle between the first inclined support rod and the support base.

[0014] In one possible implementation, the slope support formwork support frame also includes a rotating rod, and the support structure also includes a connecting piece fixed to the other end of the threaded rod; the rotating rod is vertically inserted into one side of the connecting piece.

[0015] One possible implementation method further includes a controller and pressure sensors disposed on each pressure plate;

[0016] The controller is installed on a supporting column, and a communication module, a control mainboard module, a voice reminder module, a flashing light module and a battery module are arranged inside the controller; the control mainboard module is electrically connected to the communication module, the voice reminder module, the flashing light module, the battery module and each pressure sensor respectively.

[0017] In one possible implementation, an internal threaded hole threadedly matched with the threaded rod is provided at the inner end of the support column; and a rubber sleeve is provided between the threaded rod and the corresponding internal threaded hole.

[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] Embodiment 1

[0032] See also Figure 1 to Figure 3 The first embodiment of the present application provides a slope support template support frame, comprising a support column 1, a slope support template body 2, a rotating rod 4 and at least two support structures 5. The bottom of the support column 1 is fixed with a tilting support mechanism 11 by bolts. Figure 1 As shown in , the tilt support mechanism 11 includes a support base 111 and a tilt support rod. A plurality of fixing holes are symmetrically arranged on both sides of the bottom of the support base 111. When in use, the support base 111 is fixedly installed on the ground by bolts.

[0033] The inclined support rod is used to provide auxiliary support to the support column 1 to ensure that the support column 1 is in a vertical state. Figure 1In order to stabilize the support column 1, a plurality of inclined support rods are provided in the first embodiment, including a first inclined support rod 112 fixedly connected between the support column 1 and the support base, and two second inclined support rods 113 fixed on both sides of the support base. The two second inclined support rods are arranged in parallel and connected to the support column 1 through a transverse connecting member 114. The transverse connecting member 114 is fixed on the support column 1 so that the second inclined support rod 113 maintains a certain inclination angle with the support base 111, and the inclination angle between the second inclined support rod 113 and the support base 111 is greater than the inclination angle between the first inclined support rod 112 and the support base.

[0034] The support structure 5 includes a threaded rod 51, and the inner end of the support column 1 is provided with an internal threaded hole corresponding to the threaded rod 51, and the internal threaded hole can cooperate with the thread of the threaded rod 51. Figure 1 As shown in FIG. 1 , at least two support structures 5 are arranged on one side of the support column 1 along the height direction of the support column 1. The support structure 5 can be extended and retracted in the horizontal direction under the guidance of the threaded rod 51 to achieve contact and extrusion support for the slope support template body 2.

[0035] Furthermore, in order to prevent the threaded rod 51 from being loosened from the support column 1 during the support process, a rubber sleeve can be provided between the threaded rod 51 and the internal threaded hole of the support column 1. The surface of the rubber sleeve is rough, so that the contact surface between the threaded rod 51 and the support column 1 is no longer smooth, thereby increasing the friction between the threaded rod 51 and the support column 1 and improving the anti-loosening effect of the support frame.

[0036] The rotating rod 4 is used to adjust the contact and extrusion support force of the supporting structure 5 on the slope support formwork body 2, which relatively conveniently realizes all-round support for the slope support formwork body 2 and avoids the problem that the slope support formwork body 2 needs to be supported and fixed at different positions when being supported.

[0037] The supporting structure 5 specifically includes a connecting block 52, a mounting seat 53, a triangular supporting frame 54 and a plurality of pressing plates 55. The connecting block 52 is fixedly mounted on one end of the threaded rod 51, and one side of the connecting block 52 is vertically plugged into the rotating rod 4.

[0038] The other end of the threaded rod 51 is rotatably connected to the mounting seat 53. The rotatable connection here is a narrow sense of rotatable connection, that is, the threaded rod 51 and the mounting seat 53 only rotate relative to each other, and there is no lateral relative sliding movement tendency. The specific method of the above-mentioned rotatable connection can be connected through a ball bearing, or a corresponding limit mechanism is set on the threaded rod 51 and the mounting seat 53 to prevent the two from separating in the lateral direction, such as a structure of a ball and a spherical cavity, etc., which can meet the requirement that the threaded rod 51 cannot be separated from the mounting seat 53 along its own axis.

[0039] The mounting base 53 is fixed to the triangular support frame 54. The triangular support frame 54 is provided with at least two pressing plates 55 for supporting the slope support template body 2 on one side away from the threaded rod 51. Figures 2-3 As shown in the figure, a plurality of pressing plates 55 are equidistantly distributed along the length direction of the triangular support frame 54 and are fixed to the triangular support frame 54 by bolts. When in use, the rotating rod 4 is inserted into the connecting block 52 of the threaded rod 51, and the rotating rod 4 is rotated, so that the threaded rod 51 and the support column 1 are threadedly engaged and extended, driving the mounting seat 53 and the connected triangular support frame 54 to extend, so that the plurality of pressing plates 55 are in contact with the slope support template body 2 for extrusion support, thereby providing uniform and stable supporting force and ensuring the stability of the slope support.

[0040] In addition, in order to prevent the mounting seat 53 and the triangular support frame 54 from being deflected during the extension process, a guide seat 12 is provided below the extending side of each mounting seat 53 and the triangular support frame 54 in the first embodiment. Figures 2-3 As shown in , each guide seat 12 is vertically fixedly connected to a side of the support column 1 close to the triangular support frame 54 , and is respectively located below each triangular support frame 54 , corresponding to each triangular support frame 54 one by one.

[0041] The top of the guide seat 12 is provided with a slide groove 13. The bottom of each mounting seat 53 is fixed with a slider 56 by bolts, and the slider 56 is guided forward in the slide groove 13 of the guide seat 12, providing a stable guide for the extension of the mounting seat 53 and the triangular support frame 54, ensuring that they move along a predetermined path during the extension process, avoiding deflection, improving the directional accuracy and stability of the support structure 5 during the extension process, and reducing the structural stress and potential failure risk caused by deflection.

[0042] Compared with the prior art, the first embodiment of the present application has the following beneficial effects:

[0043] This embodiment proposes a support frame for a slope support formwork, which uses a combination of support columns and at least two independent support structures to enhance the stability of the formwork and avoid displacement or collapse of the formwork due to external forces or changes in geological conditions during construction. The threaded rods in the support structure allow precise adjustment of the engagement and extension of the support frame to adapt to slopes of different slopes and shapes, thereby improving the flexibility and adaptability of construction. The mounting seat and the threaded rod are connected by rotation and the slider and the slide groove are matched, so that the installation and adjustment process of the support structure is simple, accurate and quick to operate, reducing construction time and labor intensity.

[0044] Embodiment 2

[0045] In the solution of the first embodiment, multiple pressing plates 55 provided on the supporting structure 5 are in extrusion contact with the slope support template body 2, thereby achieving all-round support for the slope support template body 2. Furthermore, in the extrusion contact process, in order to prevent the slope support template body 2 from having cracks due to insufficient extrusion force, the second embodiment of the present application is improved as follows on the basis of the first embodiment.

[0046] Specifically, the slope support template support frame provided in the second embodiment also includes a controller 3 and a plurality of pressure sensors. Figure 1 As shown in , the controller 3 is fixed to one side of the support column 1 by bolts. A pressure sensor is provided in each of the plurality of pressing plates 55 on the triangular support frame 54 of each support structure 5 threadedly connected to the support column 1. The plurality of pressing plates 55 on the triangular support frame 54 of each support structure 5 contacts with the slope support template body 2, generating a pressing plate pressure. Through the pressure sensor, the pressing plate pressure value of each pressing plate 55 when in contact with the slope support template body 2 can be obtained in real time.

[0047] The controller 3 is internally provided with a communication module, a control mainboard module, a voice reminder module, a flashing light module and a battery module. Among them, the battery module is used to provide power for the controller 3. The communication module is an Internet of Things chip and is wirelessly connected to an external control terminal. Through the Internet of Things chip, the communication module is wirelessly connected to the external control terminal to improve intelligence. The battery module is used to provide power for the controller 3. The control mainboard module is electrically connected to the communication module, the voice reminder module, the flashing light module and the battery module respectively, and is used to control each module to perform a corresponding function.

[0048] The control mainboard module is electrically connected to the pressure sensors in each pressure plate 55, so as to obtain the real-time pressure value of each pressure plate. Subsequently, the control mainboard module processes and judges the real-time pressure value of each pressure plate 55, and determines in real time whether the pressure value of each pressure plate reaches the set pressure value. If not, the voice reminder module and the flashing light module remain closed. If reached, the voice reminder sounds and the flashing light flashes to remind the staff that the support is qualified, thereby greatly improving the qualified rate of the support frame for the slope support formwork, and preventing cracks from appearing in the support of the slope support formwork body 2, resulting in unqualified pouring.

[0049] The second embodiment also provides a method for constructing a slope support formwork support frame, which specifically includes the following steps:

[0050] S1. Construction workers fix the support column 1 on the ground through the tilt support mechanism 11.

[0051] S2. Adjust the multiple support structures 5 that are threadedly connected to the support columns so that the multiple support structures 5 are close to the slope support formwork body 2.

[0052] S3, vertically insert the rotating rod 4 into the connecting block 52 of the threaded rod 51, rotate the rotating rod 4, so that the threaded rod 51 and the support column 1 are threadedly engaged and extended, driving the mounting seat 53 and the connected triangular support frame 54 to extend. At the same time, the slider 56 is guided forward in the slide groove 13 of the guide seat 12, so that the multiple pressing plates 55 on the supporting structure 5 are in contact with the slope support template body 2 for extrusion support. The other supporting structures 5 are operated in the same way, so as to relatively conveniently realize the all-round support of the slope support template body 2, which will not be repeated here.

[0053] S4. During the process of multiple pressing plates 55 on the triangular support frame 54 of each supporting structure 5 contacting and squeezing the slope support template, the construction personnel monitor the prompt information issued by the controller 3 in real time. When the voice prompt sounds and the flashing light flashes, it indicates that the pressing plate pressure value of each pressing plate reaches the set pressure value and the support is qualified.

[0054] Compared with the prior art, the second embodiment of the present application has the following beneficial effects:

[0055] The second embodiment further optimizes the technology of the first embodiment by integrating pressure sensors on multiple pressure plates of the support structure and working in coordination with the controller to achieve accurate monitoring of the degree of compression of the contact surface of the slope support template body, ensuring that the slope support template will not have gaps due to insufficient compression during the construction process, thereby avoiding possible leakage of concrete or substandard pouring quality during concrete pouring. At the same time, it simplifies the quality inspection steps during the construction process, effectively improves work efficiency, reduces errors caused by human factors, reduces construction risks, and provides a solid guarantee for project quality.
