Description

Technical Field

[0001] The utility model belongs to the technical field of building construction tire frame support, and specifically relates to an adjustable supporting tire frame. Background Art

[0002] In recent years, with the development of bridge construction, the initial cast-in-place prefabricated beams have gradually evolved into prefabricated ones. The application of prefabricated technology in bridge construction has become more and more mature. Prefabricated components have the advantages of factory-based centralized production to ensure the stability of the production process, high precision, high utilization of automated machinery, high production efficiency, cost savings and site savings. Due to external factors such as project type and transportation limitations, prefabricated components must be assembled in specific tire frames for specific products.

[0003] The patent with publication number CN219930737U discloses a portable, detachable and recyclable bridge deck assembly frame. The frame can adjust the support height and the support spacing at the same time. However, the height of the frame can only be adjusted by adding or reducing steel plates on the cushion beam, and the bridge often needs to be assembled as a whole or n+1 (one span is reserved as the mother frame) to match the next segment. For example, taking the standard span of 30m and the minimum assembled segment of 1+1 as an example, the shortest distance of one assembly is 60m, and the longitudinal slope is 0.3%, the height difference is 18 cm, that is to say, from 1 meter to the 60th meter, the corresponding height needs to be increased successively until the 18 cm high steel plate. These steel plates need to be adjusted and increased in sequence according to the longitudinal slope of 0.3%. The workload and anti-overturning risk are very large. This does not include the pre-arch height of 1 / 1000 to 3 / 1000 and the 2% transverse slope in the width direction that need to be adjusted, and the mother frame must be adjusted to the original height after each round of assembly. Otherwise, the height will be increased by 18 cm in each round of subsequent assembly, and the safety risk will also increase accordingly. Therefore, the disadvantages of the tire frame when adjusting the height are low precision and high labor, and in order to extract the steel plate, a jack or other auxiliary tools are needed to support the bottom of the component before the steel plate can be replaced.

[0011] When the slide plate needs to be locked and fixed to the upper end surface of the I-shaped slide rail, the adjusting bolt is adjusted to pull the two connecting plates closer to each other, driving the two C-shaped buckles to be clamped on both sides of the upper end surface of the I-shaped slide rail respectively.

[0012] Furthermore, the connecting tie rod between the two first support rods located on the same slide rail includes a sleeve, and a telescopic rod telescopically connected to both ends of the sleeve, one end of the telescopic rod facing away from the sleeve is connected to one of the first support rods, and the other end of the telescopic rod facing away from the sleeve is connected to the other first support rod.

[0013] Furthermore, the sleeve is threadedly connected to the corresponding telescopic rod.

[0014] Furthermore, each of the first support rods is provided with an ear plate, and the connecting tie rod is connected to the corresponding first support rod via the ear plate.

After the rough adjustment is completed, the bowl-shaped nut is rotated to drive the screw rod to rise or fall according to the actual construction situation to achieve fine adjustment. Because the bowl-shaped nut is connected to the screw rod through threaded matching, the adjustment accuracy is high when fine-tuning the height, which can meet the requirements of refined construction, and the height fine adjustment can be achieved by only screwing the bowl-shaped nut, without the need to use auxiliary tools such as jacks to lift the body to be supported, thereby improving work efficiency and reducing labor.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Combination Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present application provides an adjustable tire support frame, including a base 1, on which four first support rods 2 are arranged in a rectangular array, and a second support rod 3 is telescopically inserted in each first support rod 2, and the upper end of the second support rod 3 is rotatably covered with a bowl-shaped nut 4, and the bowl-shaped nut 4 is matched and connected with a screw 5, the lower end of the screw 5 is movably inserted in the second support rod 3, and the upper end of the screw 5 is connected to a support plate 6.

[0034] In other words, the adjustable support tire frame can meet the support requirements in various occasions. The tire frame is mainly composed of a base 1, a first support rod 2, a second support rod 3, a bowl-shaped nut 4, a screw 5 and a support plate 6. The base 1 is the foundation of the entire support tire frame. Its design is sturdy and stable, and it can effectively bear the weight of the entire tire frame. On the base 1, four first support rods 2 are arranged in a rectangular array. This design not only ensures the stability of the tire frame, but also facilitates the adjustment of the overall height of the tire frame. Each second support rod 3 can be telescopically operated inside the corresponding first support rod 2. This design allows the height of the tire frame to be flexibly adjusted as needed. At the same time, the upper end of the second support rod 2 is designed with a rotatable cover provided with a bowl-shaped nut 4. The design of the bowl-shaped nut 4 allows it to fit closely with the second support rod 3 to prevent displacement during rotation. The bowl-shaped nut 4 is matched with a screw 5, and the screw 5 can be driven to move up and down by rotating the bowl-shaped nut 4. The lower end of the screw rod 5 is movably inserted into the second support rod 3, so that the screw rod 5 can perform stable lifting and lowering movements in the second support rod 3. At the same time, the upper end of the screw rod 5 is connected to a support plate 6, which serves as the load-bearing surface of the entire tire frame. The support plate 6 is designed to be flat and sturdy, and can effectively carry the items that need to be supported.

[0035] Exemplarily, the bowl-shaped nut 4 can be directly covered on the top of the second support rod 3. Of course, the two can also be connected by a bearing, and such a design can make the bowl-shaped nut 4 rotate more smoothly.

[0036] During use, the base 1 is placed under the object to be supported, and the object to be supported is placed on the support plate 6; the height is roughly adjusted by controlling the second support rod 3 to extend or retract the first support rod 2; the height is finely adjusted by controlling the bowl-shaped nut 4 to rotate clockwise or counterclockwise to drive the screw rod 5 to rise or fall. In other words, the user can adjust the telescopic length of the combination of the first support rod 2 and the second support rod 3 as needed, thereby achieving a rough adjustment of the overall height of the tire frame. At the same time, by rotating the bowl-shaped nut 4 and driving the screw rod 5 to move up and down, the height of the support plate 6 can be finely adjusted to meet different support requirements. The adjustable support tire frame can adapt to various construction conditions that require fine adjustment. At the same time, it has a simple structure and is easy to operate, so that users can easily get started during use and improve work efficiency. The adjustable support tire frame is a support device with comprehensive functions, simple operation, and strong stability, and is suitable for various occasions where the support height needs to be flexibly adjusted.

[0037] Preferably, Figure 2 As shown, a rotating handle 12 is provided on the bowl-shaped nut 4, which is convenient for holding and the rotating operation is more convenient.

[0038] In one embodiment, if Figure 1As shown, the base 1 includes two slide rails 100 arranged opposite and in parallel, and a connecting rod 101 connecting the two slide rails 100. Exemplarily, a connecting rod 101 is connected to each of the two parallel slide rails 100 near both ends, and both ends of the connecting rod 101 are detachably connected to the corresponding slide rails 100, for example, the two are connected by a connecting block and a bolt.

[0039] Two sliding assemblies 7 are slidably matched on each slide rail 100, each sliding assembly 7 can be locked and fixed with the corresponding slide rail 100, and each sliding assembly 7 is correspondingly connected to a first support rod 2. Two adjacent first support rods 2 are connected by a connecting tie rod 8, and the length of the connecting tie rod 8 between the two first support rods 2 on the same slide rail 100 is adjustable.

[0040] Specifically, when it is necessary to adjust the distance between the two first support rods 2 on the same slide rail 100, first release the locking state of the sliding component 7 and the corresponding slide rail 100, change the distance between the two sliding components 7 to the required requirement, and adjust the length of the connecting rod 8 at the same time; finally, lock and fix the sliding component 7 to the corresponding slide rail 100, and the distance adjustment between the two adjacent first support rods 2 can be quickly completed to meet different support requirements.

[0041] Compared with using steel plates as the tire frame foundation, the base 1 of this embodiment is more stable and saves materials. Specifically, if a steel plate foundation is used, it needs to be fully paved, and the consumption of steel plates is very large. The way it is fixed to the support column is bolted, and holes need to be opened according to the actual needs of the site. The holes opened cannot be recycled, and large-area holes are opened, which wastes manpower and reduces the strength of the steel plate. When installing the high bolt fixed with it, the steel plate needs to be suspended in the air, and the nut needs to be fixed under the steel plate to tighten the high bolt. Usually, the exposed threads of the high bolt are 2-3 threads. If there are more exposed threads, there will be more contact with the ground. The steel plate is suspended in the air and cannot be closely attached to the ground and cannot serve as a foundation. The short exposed threads cannot guarantee the tightening effect. Therefore, compared with this, the base design of this embodiment can flexibly adjust the spacing, can be recycled, has a stable and reliable structure, and has low cost.

[0042] Better, combined Figure 4 and Figure 5 As shown, the slide rail 100 is an I-shaped slide rail, and the sliding assembly 7 includes a slide plate 700 slidably arranged on the upper end surface of the I-shaped slide rail, and an adjustable lock 701 for locking and fixing the slide plate 700 to the upper end surface of the I-shaped slide rail; the slide plate 700 is fixedly connected to the corresponding first support rod 2. Exemplarily, the I-shaped slide rail is made of double-jointed I-beams.

[0043] That is to say, by controlling the adjustable lock 701, the slide plate 700 and the I-shaped slide rail can be in a locked and fixed state or an unlocked state.

[0044] As a preferred embodiment, Figure 4 and Figure 5 As shown, the adjustable lock buckle 701 includes a C-shaped buckle 701a which is set in a mirror image and pressed on the slide plate 700, and the top ends of the two C-shaped buckles 701a are respectively connected to connecting plates 701b which are set opposite to each other, and the two connecting plates 701b are connected by adjusting bolts 701c. Specifically, when the slide plate 700 needs to be locked and fixed to the upper end surface of the I-shaped slide rail, the adjusting bolts 701c are adjusted to pull the two connecting plates 701b closer to each other, and drive the two C-shaped buckles 701a to be clamped on both sides of the upper end surface of the I-shaped slide rail.

[0045] In other words, this embodiment adopts a simple clamp-like design to conveniently and quickly realize the control of the connection state between the slide plate 700 and the I-shaped slide rail. When the control adjustment bolt 701c pulls the two connecting plates 701b closer to each other, the two connecting plates 701b respectively drive the corresponding C-shaped buckles 701a closer to each other until the two C-shaped buckles 701a are respectively clamped on both sides of the upper end surface of the I-shaped slide rail, and locking and fixing can be achieved. When the locking and fixing needs to be released, it is only necessary to reversely rotate the adjustment bolt 701c to unlock it.

[0046] Preferably, a chamfer is provided inside the C-shaped buckle 701a, and when the adjusting bolt 701c pulls the two connecting plates 701b closer to each other, the buckle will become tighter and tighter, and even if the bottom plate of the connecting plate is deformed or the thickness deviation of the connecting plate is too large, the C-shaped buckle 701a can be ensured to be clamped.

[0047] In one embodiment, in combination Figure 1 and Figure 2 As shown, the connecting tie rod 8 between two first support rods 2 on the same slide rail 100 includes a sleeve 800 and a telescopic rod 801 telescopically connected to both ends of the sleeve 800, one end of the telescopic rod 801 away from the sleeve 800 is connected to one first support rod 2, and the other end of the telescopic rod 801 away from the sleeve 800 is connected to the other first support rod 2. In other words, the length adjustment of the connecting tie rod 8 is achieved by extending the telescopic rod 801 into or out of the sleeve 800. Compared with arranging a large number of lugs around the support column and adjusting by changing the X-connection system and the lugs at different positions (because the lugs are fixed and the X-connection system is also fixed in length, the distance can only be adjusted by changing the connection position of the lugs), the design method of this embodiment is simpler to operate and has a low design cost (because there are many lugs, which is labor-intensive and time-consuming to process).

[0048] Better, such as Figure 2 As shown, the sleeve 800 is threadedly connected to the corresponding telescopic rod 801, that is, the length of the connecting rod 8 can be quickly adjusted by screwing, and the threaded connection has high reliability.

[0049] For example, an internal thread is provided in the sleeve 800, and an external thread is provided at one end of the telescopic rod 801 connected to the sleeve 800, so that the two are threadedly connected. It should be understood that the threads on the two telescopic rods 801 have opposite rotation directions.

[0050] Better, combined Figures 1 to 3 As shown, a lug plate 9 is provided on each first support rod 2, and the connecting tie rod 8 is connected to the corresponding first support rod 2 through the lug plate 9. In more detail, the connecting tie rod 8 is connected to the lug plate 9 through a bolt assembly. Exemplarily, the lug plate 9 is fixed to the first support rod 2 by welding.

[0051] More preferably, Figure 1 and Figure 2 As shown, two adjacent first support rods 2 are connected by two connecting tie rods 8 arranged in an X shape, which provides better stress resistance and more reliable connection reinforcement.

[0052] In one embodiment, in combination Figures 1 to 3 As shown, elevation adjustment holes 10 are provided on the first support rod 2 and the second support rod 3. The first support rod 2 and the second support rod 3 are connected in a telescopic manner by inserting a latch 11 into the elevation adjustment holes 10 facing each other on the first support rod 2 and the second support rod 3, so that the first support rod 2 and the second support rod 3 can be easily adjusted. For example, the elevation adjustment holes 10 are evenly distributed.

[0053] In the support frame provided in one embodiment, after adjusting the position of the support rods, the four support rods are fixed to the slide rails through the sliding assembly. According to whether the assembled components are assembled in a whole joint or the segments to be assembled require n+1 segments to be assembled at the same time to ensure the bridge line shape, longitudinal slope and pre-arching, the elevation is adjusted according to the above elevation requirements. In the face of beam bridge blocks with different cross-sectional heights and different spans, if the long-line method is used for assembly or the whole joint assembly or the longitudinal slope is large, the support rods (coarse adjustment) + bowl-shaped nuts and screws (fine adjustment) need to cooperate with each other to adjust the elevation. The measured line shape, transverse slope, longitudinal slope, and pre-arching values ​​are adjusted according to the design values ​​of each point using the fine adjustment structure to meet the design requirements. It is more accurate and convenient to operate than the traditional elevation adjustment by adding or removing steel plates. For the assembly of bridges with complex spatial structures such as large and extra-large beam bridges, if the distance needs to be adjusted according to the stress points of the beams and slabs, it can be adjusted arbitrarily on the double-jointed I-beam base, the relative position of the support rods can be adjusted according to the required distance, and the connecting tie rods can be extended or shortened accordingly to connect them with the ear plates on the support rods, so that the adjustment can be conveniently and quickly realized according to the beams of different forms and different stress points; when the spatial dimensions of the bridge deck are large, the structure is irregular and the stress is unstable, multiple groups of support frames can be added, and the connecting tie rods can be used to connect the groups of support frames. No other auxiliary measures can be added to complete the assembly. The process is simple and can achieve prefabricated construction, improve the reuse rate of materials, and improve construction efficiency. The support rods and the double-jointed I-beam rails, support rods and connecting tie rods laid on the ground are detachable and retractable. They can be selected and used according to the specific conditions on site. They are easy to install and disassemble and can be recycled.
