Description

Technical Field

[0001] The invention relates to the technical field of construction engineering, and in particular to a highly efficient and stable beam bottom formwork supporting device. Background Art

[0002] Beam bottom formwork is a formwork used to support the pouring of concrete at the bottom of the beam in construction. It is mainly divided into three types: wooden formwork, steel formwork and plastic formwork. The main reason for setting a support frame at the bottom of the beam is that the beam bottom formwork needs to bear vertical loads. Setting a support frame (such as a bracket or a support rod) can effectively disperse the weight and pressure of the beam, enhance the stability and safety of the beam bottom, prevent the beam bottom from sagging, deformation or fracture, and ensure the overall stability and construction quality of the building structure.

[0003] The support frame is mainly composed of several vertical poles, horizontal poles, sweeping poles, diagonal braces, adjustable drag braces, bases and pads, and the connection between the steel pipes is connected by fasteners. The fasteners used for this connection mainly include butt fasteners, rotating fasteners and right-angle fasteners. Butt fasteners ensure that the two vertical poles can be firmly and accurately connected to each other to form a continuous and rigid support structure. Butt fasteners effectively transfer and disperse the load between the vertical poles through their unique design and fastening mechanism, enhancing the stability and bearing capacity of the entire building frame. They are an indispensable connection component in construction projects and are of great significance for ensuring construction safety and improving building quality.

[0004] However, for different sizes of beam bottom formwork, the sizes of supporting uprights required are also different, so the supporting uprights have many different sizes. However, in order to ensure the connection with the uprights, the sizes of the butt fasteners are usually matched with the sizes of the uprights. Due to the inconsistency of the sizes of the uprights, the butt fasteners are also inconsistent, and this type of butt fastener has great limitations. Therefore, it does not meet the existing needs. In this regard, we propose an efficient and stable beam bottom formwork support device. Summary of the invention

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment 1, this embodiment is intended to promote the solution of the problem that the existing butt fastener 2 has a fixed size and needs to be used in conjunction with the vertical pole 11, which has great limitations. Please refer to Figures 1 to 10 A highly efficient and stable beam bottom formwork support device comprises a support assembly 1, wherein the support assembly 1 comprises a plurality of vertical poles 11 and a horizontal pole 12, wherein the number of vertical poles 11 is determined according to the area or number of beam bottom formworks to be supported on site, and is not specifically limited here, wherein the vertical poles 11 are connected by a butt fastener 2, wherein the butt fastener 2 comprises a truncated cone 21 and a cross rod 22, wherein the truncated cone 21 and the cross rod 22 are fixedly connected, wherein an extension assembly 3 is arranged in the truncated cone 21, wherein the extension assembly 3 is used for expanding the support diameter of the truncated cone 21, and can be applied to the connection between vertical poles 11 of different diameters.

[0034] The intersecting vertical rods 11 and horizontal rods 12 are connected by right-angle fasteners to form a bracket to ensure support for the bottom formwork of the beam.

[0035] The truncated cone 21 is arranged between two adjacent vertical poles 11, and two clamping rings 23 are arranged on the side wall of the truncated cone 21, and the clamping rings 23 are used to tighten the vertical poles 11 on both sides of the truncated cone 21, and one end of the clamping ring 23 is fixedly connected with a fastening block 24, and one side of the fastening block 24 is provided with a bolt 25 and a nut 26.

[0036] After the workers have completed the beam formwork, since the middle of the beam is in a suspended state and cast-in-place concrete is required in the formwork, in order to ensure the load-bearing effect of the beam formwork, a support assembly 1 needs to be set at the bottom of the beam bottom formwork to ensure that the beam formwork can support the weight of the cast-in-place concrete. The support assembly 1 is mainly composed of vertical poles 11 and horizontal poles 12, and the connection between the vertical poles 11 is connected by a butt fastener 2. As a prior art, the butt fastener 2, under the tightening action of the bolts 25 and the nuts 26, tightens the two clamping rings 23 arranged on both sides of the truncated cone 21 inward, and also tightens the two vertical poles 11 installed on the side walls of the truncated cone 21, thereby ensuring a stable connection between the two vertical poles 11.

[0037] The truncated cone 21 is the core part of the butt fastener 2, and its main function is to connect the two vertical poles 11. By matching its shape and size with the inner diameter of the vertical pole 11, the truncated cone 21 can be tightly inserted into the vertical pole 11, thereby realizing a stable connection between the two vertical poles 11. This connection not only ensures the integrity of the structure, but also improves the overall bearing capacity.

[0038] The extending component 3 includes an empty slot 31 and an extending slot 32 opened in the truncated table 21, an extending block 33 is slidably connected in the extending slot 32, one side of the extending block 33 is rotatably connected to a connecting rod 34, the other end of the connecting rod 34 is rotatably connected to a driving cylinder 36, the bottom of the driving cylinder 36 is inserted in a fixed shaft 35, a No. 1 spring 37 is arranged between the driving cylinder 36 and the fixed shaft 35, the fixed shaft 35 is fixedly connected in the empty slot 31, and one end of the driving cylinder 36 extends out of the cross rod 22.

[0039] The extension component 3 is designed to flexibly adjust the outer dimensions of the truncated table 21 to accommodate vertical poles 11 of different diameters. The truncated table 21 is a core component responsible for bearing and transmitting the load from the vertical poles 11, and the vertical poles 11 are respectively arranged on the upper and lower surfaces of the truncated table 21.

[0040] In actual operation, the user only needs to simply press the drive cylinder 36 to make it slide downward. Through the clever rotation connection of the connecting rod 34, the extension block 33 can slide outward under the guidance of the extension groove 32. This design ensures that the extension block 33 can move smoothly along the preset direction, thereby accurately adjusting the diameter of the table 21 according to the actual size of the vertical pole 11.

[0041] The two ends of the connecting rod 34 are connected to the extension block 33 and the driving cylinder 36 through a rotating block, which is mainly connected by a base and an axis. This connection method is simple and convenient (this connection method is a prior art and will not be described in detail).

[0042] This innovative design gives the docking fastener 2 unprecedented versatility. Regardless of the diameter of the vertical pole 11, the table 21 can be adjusted in real time during the installation process to ensure a perfect fit. This feature effectively solves the limitations of the docking fastener 2 in the prior art, namely the need to be used in conjunction with a vertical pole 11 of a specific size.

[0043] Through the ingenious design of the extending component 3, the user no longer needs to prepare a variety of docking fasteners 2 for vertical poles 11 of different sizes, which greatly saves cost and time. At the same time, the design also improves the flexibility and practicality of the docking fastener 2, so that it can be widely used in various construction and engineering fields.

[0044] Exemplary: As reusable components, the vertical pole 11 and the butt fastener 2 are often subject to wear and tear during use. During the connection process between the vertical pole 11 and the butt fastener 2, the inner wall of the vertical pole 11 is always in contact with the outer wall of the inner cone 21 of the butt fastener 2 and the inner wall of the clamping ring 23. These contact surfaces serve as load transfer surfaces. After long-term use, these parts will have their diameters reduced due to wear. In this solution, the butt fastener 2 can be adjusted in real time according to the change in the inner diameter of the vertical pole 11 during use through the extension design of the extension block 33, further ensuring that the connection between the inner wall of the vertical pole 11 and the butt fastener 2 is more stable, avoiding the unstable connection between the vertical pole 11 and the butt fastener 2 due to wear, and further improving the stability effect of the support component 1 on the beam bottom formwork.

[0045] Embodiment 2: This embodiment is intended to facilitate solving the problem that the length of the extension block 33 needs to be set with different restrictions according to the different sizes of the vertical pole 11. This embodiment is an explanation made on the basis of Embodiment 1. For details, please refer to Figures 1 to 10 A control component 4 is disposed inside the cross rod 22 , and the control component 4 is used to control the extension range of the extension component 3 , thereby further improving the connection between the vertical rod 11 and the docking fastener 2 .

[0046] The control assembly 4 includes a control slot 41 opened on the top of the cross rod 22, a scale rod 42 is fixedly connected in the control slot 41, a control slider 43 is slidably connected in the control slot 41, a mounting slot 48 is opened in the control slider 43, a shaft rod 44 is fixedly connected in the mounting slot 48, and the outer wall of the shaft rod 44 is rotatably connected to a scale block 46 through a torsion spring 45.

[0047] One side of the control slider 43 is rotatably connected to a rotation link 47 , and the other end of the rotation link 47 is rotatably connected to the outer side wall of the driving cylinder 36 .

[0048] The control assembly 4 is specially designed for adjusting the extension length of the extension block 33. It can be accurately adjusted and fixed according to the inner diameter of the vertical rod 11. When the driving cylinder 36 slowly descends, the control slider 43 will slide smoothly to both sides (such as Figure 7 As shown, it slides to the left), at this time, the scale block 46 inside the control slider 43 will rotate downward under the push of the scale rod 42 until it slides to another empty position, and then bounces open under the elastic force of the torsion spring 45, and is firmly stuck in the gap between the scale rods 42. The No. 1 spring 37 is responsible for the upward reset of the drive cylinder 36. At the same time, due to the engagement of the scale block 46 with the scale rod 42, the scale block 46 is always pressed against one side of the scale rod 42 under the push of the No. 1 spring 37, which ensures the stability of the extension distance of the extension block 33 and effectively avoids excessive retreat, thereby fully demonstrating the limiting effect of the control component 4.

[0049] A recovery component 5 is provided in the control slider 43, and the recovery component 5 includes a recovery chute 51 opened in the control slider 43, a recovery rack 52 is slidably connected in the recovery chute 51, and the recovery rack 52 is meshingly connected with a recovery tooth block 53, and the recovery tooth block 53 is fixedly connected to the outer wall of the scale block 46, and the recovery chute 51 is connected to the cross drive groove 55 through a pneumatic channel 54, and the cross drive groove 55 is opened at the top of the drive cylinder 36, and a cross drive rod 56 is slidably connected in the cross drive groove 55, and the bottom of the cross drive rod 56 is slidably connected in the cross drive groove 55 through a No. 2 spring 57.

[0050] The pneumatic channel 54 includes a channel No. 1 541 opened in the control slider 43, a channel No. 2 543 opened in the rotating connecting rod 47, and a channel No. 3 545 opened in the driving cylinder 36. The channel No. 1 541 and the channel No. 2 543 are connected by a No. 1 hose 542, and the channel No. 2 543 and the channel No. 3 545 are connected by a No. 2 hose 544.

[0051] The design of the recovery component 5 focuses on controlling the rotation direction of the scale block 46 so as to smoothly recover the protruding block 33. During the disassembly process, the user only needs to gently press the cross drive rod 56 to squeeze the gas at the bottom of the cross drive groove 55. This gas is transmitted through the pneumatic channel 54 to push the recovery rack 52 to slide, thereby driving the scale block 46 equipped with the recovery gear block 53 to rotate. As the scale block 46 rotates into the installation groove 48, the drive cylinder 36 slowly rises under the elastic force of the No. 1 spring 37, thereby driving the control slider 43 and the protruding block 33 to reset. This ingenious design ensures the smooth disassembly of the docking fastener 2. The whole process is efficient and convenient. Through the coordinated work of the control component 4 and the recovery component 5, the entire system realizes precise control of the extension and recovery of the protruding block 33.

[0052] Embodiment 3, this embodiment is intended to promote the solution of the problem that the notch formed by the extension block 33 after extension and the installation of the extension assembly 3 reduces the compressive strength of the truncated table 21. This embodiment is an explanation based on the embodiment 2. For details, please refer to Figures 1 to 10 A filling component 6 is provided in the truncated cone 21 , and the filling component 6 is used to fill the hollow area formed in the truncated cone 21 to ensure the strength of the truncated cone 21 .

[0053] The filling assembly 6 includes a cross groove 61 opened in the cross rod 22, a cross sliding plate 62 is slidably connected in the cross groove 61, a rubber elastic isolation membrane 64 is arranged in the empty groove 31 and the extended groove 32, the rubber elastic isolation membrane 64 is connected to the cross groove 61 through a filling flow channel 63, and the filling flow channel 63 is opened between the cross rod 22 and the frustum 21.

[0054] The filling assembly 6 is designed to fill the hollow inside the truncated cone 21, thereby ensuring the overall strength of the truncated cone 21. By filling the hollow inside the truncated cone 21 with materials, the structural strength of the truncated cone 21 is improved. In terms of the selection of filling materials, in order to ensure practicality and economy, the selection of filling materials for filling the hollow inside the truncated cone 21 is carried out through the following comparative analysis: Metallic particles: Although they have high compressive strength, they are more expensive and their weight may have a negative impact on the overall performance of the disc.

[0055] Polystyrene foam and polyurethane foam: The compressive strength is relatively low and may not meet the application scenarios with high strength requirements.

[0056] Plastic pellets: Although they have a certain degree of compressive strength, they may cost more than sand, and the recycling process may be relatively complicated.

[0057] Concrete: Although it has high compressive strength, it is difficult to replace or recycle once poured and has poor flexibility.

[0058] Rubber granules: Mainly used to improve earthquake resistance, they have relatively low compressive strength and may cost more than sand.

[0059] Sand is the best choice. In terms of economy, sand is a common building material with a wide range of sources and relatively low cost. Compared with other filling materials (such as metal particles, polystyrene foam, polyurethane foam, plastic particles, etc.), the procurement cost of sand is usually lower. In terms of practicality, sand has good compaction and fluidity, which can effectively disperse pressure and improve the compressive strength of the disc. Through proper compaction treatment, the compressive strength of sand can be further improved. Sand has strong adaptability to the environment and will not undergo significant performance changes due to changes in external conditions such as temperature and humidity.

[0060] Due to the fluidity of sand, in order to prevent part of the sand from getting stuck in the internal moving parts when entering the hollow area of ​​the truncated cone 21, causing the internal moving parts to be unable to move, a rubber elastic isolation membrane 64 is set in the hollow area of ​​the truncated cone 21. The rubber elastic isolation membrane 64 has an isolation effect and has the ability of elastic deformation. Therefore, it can expand as the protruding block 33 in the truncated cone 21 extends, and the expanded space in the truncated cone 21 needs to be filled with new sand. Therefore, a cross groove 61 is set in the cross rod 22, and the cross groove 61 is also filled with sand. As the driving cylinder 36 descends, the cross sliding plate 62 fixedly connected to the side wall of the driving cylinder 36 slides downward synchronously and squeezes the sand in the cross groove 61, driving the sand into the rubber elastic isolation membrane 64 in the truncated cone 21 through the filling flow channel 63. Under the action of the rotating component 7, the sand can be evenly filled in the rubber elastic isolation membrane 64, thereby ensuring the stability of the internal structure of the truncated cone 21.

[0061] A rotating assembly 7 is provided in the filling flow channel 63, and the rotating assembly 7 includes a T-shaped positioning rod 71 fixedly connected to the inner wall of the rubber elastic isolation membrane 64, and the top of the T-shaped positioning rod 71 is rotatably connected to a rotating spiral rod 72, and the top of the rotating spiral rod 72 is provided with a plug-in groove 73 and a spiral groove 75, and a plug-in rod 74 is plugged into the plug-in groove 73, and a spiral slider 76 is fixedly connected to the side wall of the plug-in rod 74, and the spiral slider 76 is slidably connected in the spiral groove 75.

[0062] The design of the rotating component 7 is used to ensure the uniformity of sand entering the rubber elastic isolation membrane 64. During the descent of the cross sliding plate 62, the plug-in rod 74 slides downward synchronously in the plug-in groove 73. Since a spiral slider 76 and a spiral groove 75 are provided between the plug-in rod 74 and the rotating screw rod 72, the rotating screw rod 72 rotates during the descent of the plug-in rod 74. Through the rotation of the rotating screw rod 72, the sand can move with the spiral leaves of the side wall of the rotating screw rod 72. This design ensures that the sand in the cross groove 61 can smoothly enter the rubber elastic isolation membrane 64. At the same time, the spiral design of the rotating screw rod 72 can evenly transport the sand to various parts of the rubber elastic isolation membrane 64. At the same time, in order to further ensure the uniformity of the sand, the user can bridge the docking fastener 2 after the adjustment is completed, so that the internal sand is more evenly filled in the rubber elastic isolation membrane 64, thereby ensuring the overall strength of the truncated table 21 and the supporting strength of the support component 1 on the beam bottom formwork.

[0063] During recycling, due to the elastic design of the rubber elastic isolation membrane 64 and the reverse rotation of the rotating screw rod 72, the sand can be transported upward again to facilitate the next filling.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0065] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
