Description

Technical Field

[0001] The utility model relates to a supporting device, in particular to an improved temporary supporting device for prefabricated T-beams, which is mainly used for temporarily reinforcing and supporting the T-beams during the prefabrication of the T-beams so as to prevent them from tipping over, and belongs to the technical field of auxiliary supporting and reinforcing technology for construction supplies. Background Art

[0002] Generally speaking, T-beams are the most common form of bridges in the current highway bridge construction. During the process of prefabricated T-beams being poured and maintained on prefabricated pedestals, or after the prefabricated beam slabs are prefabricated on the pedestals in the prefabrication yard and the side forms are removed, or during the process of beam transfer and storage, in order to prevent the structure from overturning, it is necessary to effectively support it to prevent it from overturning. Because the lateral stability of prefabricated T-beams is poor, temporary support is required to prevent the lateral overturning of the prefabricated T-beams and cause production safety accidents.

[0003] In the process of construction, for the sake of convenience, it is usually used to support wooden blocks or steel sections on a stable ground after being wedged tightly by wedges. Due to the unevenness of the ground, it is necessary to cut wooden blocks or steel sections of different lengths and process wedges of various specifications at different support heights during the support process, which not only wastes support materials, but also is time-consuming and labor-intensive, and the support operation cannot be performed quickly.

[0004] After searching, Chinese utility model patent CN217026688U discloses a temporary support device for a prefabricated T-beam, comprising a bottom support (1), a support rod (2), an adjustable screwing member (3), a lifting sleeve (4) and a support top plate (5) arranged in sequence from bottom to top, one end of the support rod (2) is connected to the bottom support (1), and the other end is connected to the lifting sleeve (4), the lifting sleeve (4) and the support rod (2) are lifted and lowered in coordination and are fixed and limited by the adjustable screwing member (3); the lifting sleeve (4) is connected to the support top plate (5), and a stopper (6) is symmetrically arranged at the upper end of the support top plate (5); a prestressed stress dispersion mechanism (7) is symmetrically arranged at the lower end of the support top plate (5), one end of the prestressed stress dispersion mechanism (7) is hingedly connected to the support top plate (5), and the other end is hingedly connected to the outer wall of the lifting sleeve (4);

[0005] The inner surfaces of the supporting top plate (5) and the stopper (6) are also provided with anti-skid pads (8), which are rubber pads. The outer wall of the rubber pads is provided with a plurality of rubber protective protrusions of a connected structure, and the protective protrusions are granular or annular protrusions.

[0006] Although the support device of this design structure has the same purpose as the improved prefabricated T-beam temporary support device of the present patent application, the prefabricated T-beam temporary support device of the existing structure has the following defects and shortcomings:

[0007] On the one hand, the structure is relatively complex, which not only makes it difficult to process and manufacture on the construction site, but also has high costs. Most importantly, in the actual use process, it is completely difficult to operate during installation and use. It seems that the upper end of the support top plate (5) is symmetrically provided with a stopper (6), which can play a role in limiting and fixing. In fact, it increases the difficulty in installing the support. When supporting the T-beam, it is undoubtedly necessary for the operator to pre-center and align the support T-beam so that the upper end of the support top plate (5) can just support the T-beam. Otherwise, due to the existence of the stopper (6), it will block and limit the accurate support of the T-beam, causing deflection and requiring continuous adjustment. It can be seen that the installation requirements for the operator are relatively high, especially when the space is small and the T-beam is placed at a low height, the installation and use are more difficult and time-consuming; it is difficult to meet the requirements of convenience and speed during the support process;

[0008] On the other hand, the lifting structure is relatively complex, the lifting operation is difficult, time-consuming and labor-intensive, and during use, the supporting top plate cannot be easily and quickly replaced according to actual needs or when it is damaged. In short, it is often very inconvenient.

[0009] Therefore, the key to solving the above technical problems is to develop an improved prefabricated T-beam temporary support device that is quick to install, simple and convenient to disassemble, and has high working reliability. Summary of the invention

[0010] In view of the many defects and shortcomings existing in the above-mentioned background technology, the present invention has made improvements and innovations thereto, and aims to provide a device that can meet the support height by adjusting the height, without the need for wedges. By adjusting the height, various beams or other structures that need support to prevent overturning can be effectively supported, and the device is reusable. Compared with the traditional support method, it eliminates the need to cut different lengths of wood or steel and process various specifications of wedges at different support heights, which not only saves support materials, but also allows for convenient and quick support operations. It can effectively improve work efficiency and reduce construction costs while ensuring safety.

[0011] Another invention purpose of the utility model is to have a compact design structure, which allows for quick and convenient height adjustment and occupies little space. It can achieve effective support and fixation in a limited space, thus saving space. The support device is simple in design and easy to install. It can be quickly and easily installed on a T-beam or beam that needs support, saving construction time and labor costs. It is easy to use in a small space and can provide solid support, which can effectively increase the load-bearing capacity of the T-beam or beam, enabling it to withstand greater loads, thereby improving the safety and reliability of the structure, and ensuring that the T-beam or beam maintains structural stability under the action of gravity or other external forces, thereby avoiding deformation or tilting.

[0023] As a further improvement of the above-mentioned utility model, the support sleeve (22) is further provided with a tightening hole (221), which is a bolt hole. The bolt hole passes through the front and back sides of one side wall of the support sleeve (22). After the tightening member (23) passes through the tightening hole (221), the support sleeve (22) and the upper end of the adjustable lifting rod (1) are fastened as a whole.

[0028] As a further improvement of the above-mentioned utility model, the fixing mechanism (3) further includes several reinforcing members (34) and an anti-slip pad (35), wherein:

[0029] One end of the reinforcing member (34) is connected to the outer wall of the lower end of the supporting column (31), and the other end of the reinforcing member (34) is connected to the supporting base (32);

[0030] The structure of the anti-skid pad (35) matches the structure of the support base (32), and the anti-skid pad (35) is arranged at the contact connection between the support base (32) and the ground;

[0031] Fixing holes (321) are provided at the four corners of the support base (32). The fixing holes (321) are bolt holes through which bolts pass to tighten against the ground or are connected to the ground.

[0035] A movable member (43) is threadedly connected to the other end of the connecting rod (41); wherein:

[0036] The fixed part (42) and the movable part (43) are spherical or square.

[0037] The working principle is: before using an improved prefabricated T-beam temporary support device of the above-mentioned design structure, the prefabricated T-beam temporary support device of the design structure that has been manufactured needs to be transported to the designated working position by manual or corresponding transport equipment for installation as a spare.

[0038] During installation, first, the operator only needs to carry a reasonable number of prefabricated T-beam temporary support devices to the designated work location for installation and use according to the actual needs of the construction. When using, when supporting the T-beam (5), the operator places the utility model at the bottom of the prefabricated T-beam diaphragm (51), aligns and corrects it to ensure that the placement position is accurate, and then uses the tightening member (23) to pass through the tightening hole (221) to tighten the support sleeve (22) and the upper end of the adjustable lifting rod (1) into a whole; then, according to the T-beam diaphragm (5 1), by rotating the adjustable operating member (4) with one hand or both hands, the adjustable lifting rod (1) is lifted and lowered in the supporting column (31), thereby adjusting the height of the supporting mechanism (2), until the top surface of the supporting top plate (21) is tightly fitted with the bottom surface of the T-beam diaphragm (51), thereby preventing the T-beam diaphragm (51) from being suspended after demoulding; the upper supporting top plate (21) tightly supports the T-beam diaphragm (51), thereby preventing the T-beam (5) from overturning as a whole, thereby achieving the purpose of supporting and limiting.

[0039] During the entire implementation process described above, in order to provide a more stable support, the operator can use high-strength bolts to pass through the fixing holes (321) provided on the support base (32) to stably and firmly fix the support device body on the ground or press it against the ground, thereby making its fixation more stable and reliable.

[0040] During use, if the support mechanism (2) needs to be replaced, the operator only needs to loosen the top fastener (23) and remove it, then remove the support mechanism (2) and replace it with a new one. The specific use is the same as above and will not be repeated here.

[0041] Finally, as time goes by, when the support device needs to be dismantled after use, the operator only needs to rotate the adjustable operating member (4) to lower the support device to a position where the space height is sufficient and convenient for the operator to operate. The operator then stops rotating the adjustable operating member (4). At this time, the operator takes out the high-strength bolts at the bottom from the fixing holes (321) on the support base (32), and then slowly lays the support device flat on the ground by manpower. The operator then cleans and repairs its various components and moves them to a designated storage warehouse for storage, preparing for reuse in the next project or for recycling and turnover next time.

[0042] Compared with the prior art, the utility model has the following beneficial effects:

[0043] 1. The utility model has a compact design structure and occupies little space. It can achieve effective support and fixation in a limited space, saving space. The support device is simple in design and easy to install. It can be quickly and easily installed on the T-beam or beam that needs to be supported, saving construction time and labor costs.

It has the characteristics of strong durability and easy cleaning. The maintenance is relatively simple, which can extend the service life and reduce the maintenance cost;

[0047] 5. The utility model can meet the support height by adjusting the height, without the need for wedges. After adjusting the height, various beams or other structures that need support to prevent overturning can be effectively supported, and the device can be reused.

[0048] 6. The utility model provides an anti-skid pad with protective protrusions at the contact connection between the support top plate and the T-beam diaphragm, which not only plays a protective role and ensures the structural integrity of the support top plate and the T-beam diaphragm, but also increases the friction at the connection, so that the support top plate can reliably press against the T-beam diaphragm, so that it and the T-beam diaphragm are pressed together as a whole and will not slip;

[0049] 7. The utility model provides an anti-skid pad with protective protrusions on the outside at the contact connection between the support base and the ground, which not only plays a protective role and ensures the structural integrity of the support base, but also increases the friction at the connection, so that the support base can reliably contact the ground, press against the ground as a whole, and will not slide or move, making its contact with the ground more stable and reliable.

The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0063] In summary, a more specific implementation method of the present invention is:

[0064] Example 1

[0065] An improved prefabricated T-beam temporary support device, comprising:

[0066] An adjustable lifting rod 1, one end of which is detachably connected to a supporting mechanism 2, and the other end of which is detachably inserted into a fixing mechanism 3;

[0067] The support mechanism 2 includes a support top plate 21, the upper end of the support top plate 21 is used to support the T-beam diaphragm 51; the lower end of the support top plate 21 is connected to the support sleeve 22, and the support sleeve 22 is plug-in connected to the upper end of the adjustable lifting rod 1;

[0068] A fixing mechanism 3, the upper end of which is in lifting and lowering cooperation with the adjustable lifting rod 1, and the lower end of which is in contact with or connected to the ground;

[0069] The adjustable operating member 4 is slidably arranged on the adjustable lifting rod 1 in a sleeve-like manner, and is used to manually complete the lifting and lowering of the adjustable lifting rod 1 in the fixing mechanism 3.

[0070] Further, such as Figure 5 and Figure 6 As shown, the supporting top plate 21 is a square plate-shaped component, the adjustable lifting rod 1 is a screw or lead screw with an external threaded section on the outside, or the lower section of the adjustable lifting rod 1 is a screw or lead screw with an external threaded section on the outside, and the upper section of the adjustable lifting rod 1 is a smooth round rod on the outside.

[0071] Further, such as Figure 6 As shown, the adjustable lifting rod 1 is provided with a mounting hole 11 for the adjustable operating member 4 to pass through for installation, and the mounting hole 11 runs through the front and back sides of the adjustable lifting rod 1 .

[0072] Further, such as Figure 5 As shown, the fixing mechanism 3 includes:

[0073] Support column 31;

[0074] A support base 32, the support base 32 is connected to the bottom of the lower end of the support column 31;

[0075] The threaded sleeve 33 is connected to the top of the upper end of the supporting column 31 .

[0076] In the present invention, the threaded sleeve 33 may be an elongated nut.

[0077] Further, such as Figure 6 As shown, the adjustable operating member 4 includes:

[0078] A connecting rod 41, the connecting rod 41 is slidably mounted on the adjustable lifting rod 1;

[0079] A fixing member 42, the fixing member 42 is connected to one end of the connecting rod 41;

[0080] The movable member 43 is threadedly connected to the other end of the connecting rod 41; wherein:

[0081] The fixed member 42 and the movable member 43 are spherical or square.

[0082] Before using the improved prefabricated T-beam temporary support device of the design structure of the above-mentioned embodiment 1, the prefabricated T-beam temporary support device of the design structure that has been manufactured needs to be transported to the designated working position by manual labor or corresponding transport equipment for installation as a standby.

[0083] During installation, first, the operator only needs to carry a reasonable number of prefabricated T-beam temporary support devices to the designated work position for installation and use according to the actual needs of the construction. When in use, when supporting the T-beam 5, the operator places the utility model at the bottom of the prefabricated T-beam diaphragm 51, aligns and corrects it to ensure that the placement is accurate. Then, according to the height position of the T-beam diaphragm 51, the operator rotates the adjustable operating part 4 with one hand or both hands to achieve the lifting and lowering of the adjustable lifting rod 1 in the supporting column 31, thereby adjusting the height of the supporting mechanism 2 until the top surface of the supporting top plate 21 is tightly fitted with the bottom surface of the T-beam diaphragm 51 to avoid the T-beam diaphragm 51 being in a suspended state after the demolding; the upper support top plate 21 tightly supports the T-beam diaphragm 51, so that the T-beam 5 as a whole will not overturn, thereby achieving the purpose of support limitation.

[0084] During the entire implementation process described above, in order to provide a more stable support, on the one hand, the operator can use high-strength bolts to pass through the fixing holes 321 provided on the support base 32 to stably and firmly fix the support device body on the ground or press it against the ground, thereby making its fixation more stable and reliable.

[0085] During use, if the support mechanism 2 needs to be replaced, the operator only needs to loosen the top member 23 and remove it, then remove the support mechanism 2 and replace it with a new one. The specific use is the same as above and will not be repeated here.

[0086] Finally, as time goes by, when the support device needs to be dismantled after use, the operator only needs to rotate the adjustable operating part 4 to lower the support device to a position where the space height is sufficient and convenient for the operator to operate. The operator then stops rotating the adjustable operating part 4, and then the operator takes out the high-strength bolts at the bottom from the fixing holes 321 on the support base 32, and then slowly lays the support device flat on the ground by manpower. The operator then cleans and repairs its various components and moves them to a designated storage warehouse for storage, preparing for reuse in the next project or for recycling and turnover next time.

[0089] In the present invention, the anti-skid pad 211 is a rubber protective pad, and a plurality of rubber protective protrusions of a connected structure are arranged on the outside of the rubber protective pad.

[0090] When in use, since an anti-skid pad 211 with external protective protrusions is provided at the contact connection between the support top plate 21 and the T-beam cross-plate 51, it can not only play a protective role and ensure the structural integrity of the support top plate 21 and the T-beam cross-plate 51, but also increase the friction at the connection, so that the support top plate 21 can reliably press against the T-beam cross-plate 51, so that it is pressed against the T-beam cross-plate 51 as a whole and will not slip.

[0091] The specific installation and use are the same as those in Example 1 and will not be repeated here.

[0092] Example 3

[0093] like Figure 6 As shown, the embodiment 3 is the same as the embodiment 1 and the embodiment 2, the only difference being that the support mechanism 2 further includes a tightening member 23, which is a tightening bolt.

[0094] The support sleeve 22 is also provided with a tightening hole 221, which is a bolt hole. The bolt hole passes through the front and back sides of one side wall of the support sleeve 22. After the tightening member 23 passes through the tightening hole 221, the support sleeve 22 and the upper end of the adjustable lifting rod 1 are fastened as a whole.

[0095] During use, when supporting the T-beam 5, the operator places the utility model at the bottom of the prefabricated T-beam cross partition 51, aligns and corrects it to ensure that the placement is accurate, and then uses the tightening piece 23 to pass through the tightening hole 221 to fasten the support sleeve 22 and the upper end of the adjustable lifting rod 1 into a whole.

[0096] The specific installation and use are the same as those in Example 1 to Example 2, and will not be repeated here.

[0097] Example 4

[0098] like Figure 6 As shown, this embodiment 3 is the same as embodiments 1 to 3, with the only difference being that the support mechanism 2 further includes a plurality of reinforcing members 24 , one end of the reinforcing member 24 being connected to the bottom end of the support top plate 21 , and the other end of the reinforcing member 24 being connected to the outer wall of the support sleeve 22 .

[0099] In the present invention, the reinforcement member 24 is a triangular plate-shaped structure.

[0100] When in use, due to the design of the reinforcement 24, it can provide solid support, which can effectively increase the load-bearing capacity of the T-beam or the crossbeam, so that it can withstand a larger load, improve the safety and reliability of the structure, and at the same time ensure that the T-beam or the crossbeam maintains structural stability under the action of gravity or other external forces to avoid deformation or tilting.

[0101] The specific installation and use are the same as those in Examples 1 to 3 and will not be described again here.

[0102] Example 5

[0106] Fixing holes 321 are formed at the four corners of the support base 32 . The fixing holes 321 are bolt holes. Bolts pass through the bolt holes to tighten against the ground or connect to the ground.

[0107] In the present invention, the reinforcement member 34 is a triangular plate-shaped structure;

[0108] The anti-skid pad 35 is a rubber protective pad, and a plurality of rubber protective protrusions of a conjoined structure are arranged outside the rubber protective pad. The shape and structure of the anti-skid pad 35 are the same as the shape and structure of the support base 32.

[0109] When in use, the anti-skid pad 35 with an external protective protrusion is provided at the contact connection between the support base 32 and the ground, which not only plays a protective role and ensures the structural integrity of the support base 32, but also increases the friction at the connection, so that the support base 32 can reliably contact the ground, be pressed against the ground as a whole, and will not slide or move, making its contact with the ground more stable and reliable.

[0110] At the same time, due to the design of the reinforcement 34, it can provide solid support again, which can effectively increase the bearing capacity of the T-beam or beam, so that it can withstand a larger load, improve the safety and reliability of the structure, and ensure that the T-beam or beam maintains structural stability under the action of gravity or other external forces to avoid deformation or tilting.

[0111] The specific installation and use are the same as those of Examples 1 to 4 and will not be repeated here.

[0114] When in use, since protective covers are provided on the hand-holding parts of the fixed part 42 and the movable part 43, the hands of the operator can be protected from wear and tear during long-term work, thereby ensuring the safety of construction.

[0115] At the same time, on the basis of Examples 1 to 6, an injection molding layer, an anti-rust layer, a waterproof layer and a warning layer are arranged in sequence from the inside to the outside on the outer surfaces of the adjustable lifting rod 1, the supporting mechanism 2, the fixing mechanism 3 and the adjustable operating part 4, and the warning layer is coated with fluorescent powder.

[0116] In the utility model, a polymer wear-resistant material is injection molded on the injection molding layer; the anti-rust layer includes an epoxy zinc-rich primer and a chlorinated rubber topcoat and an epoxy micaceous iron intermediate paint located between the epoxy zinc-rich primer and the chlorinated rubber topcoat; the waterproof layer is a polyurethane waterproof coating; the warning layer is a reflective warning tape or a reflective color film or a reflective paint of a single color or a mixture of multiple colors.
