Description

Technical Field

[0001] This utility model relates to the field of protective support technology, and more specifically, to a protective support for building engineering. Background Technology

[0002] In the field of construction engineering, protective supports are crucial facilities for ensuring construction safety and isolating hazardous areas, and their use is extremely frequent. Existing construction engineering protective supports mostly rely on bolt and nut connections or welding for assembly when multiple supports are joined together. Bolt and nut connections require workers to use specialized tools for individual installation and tightening, which is cumbersome, consuming significant manpower and time. Furthermore, in complex working environments such as at heights, the operation is difficult and poses safety hazards. While welding provides a stable connection, it requires specialized welding equipment and operators, and the sparks generated during welding can potentially cause fires and other safety accidents. Additionally, welded supports are difficult to disassemble and reuse. Therefore, developing a construction engineering protective support system that is easy to assemble, provides a strong connection, and is simple to operate has significant practical significance and application value. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a protective support for building engineering, which has the advantage of being able to easily splice the supports together.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a protective support for construction projects, comprising:

[0005] A column, wherein a connecting rod and a round rod are fixedly installed on the outer surface of the column, and a connecting block is fixedly installed on one side of the column;

[0006] An assembly mechanism is provided on the outer surface of the column;

[0007] The assembly mechanism includes a vertical rod, the outer surface of which is in contact with the outer surface of the column. A roller is fixedly installed at the bottom end of the vertical rod. A fixing block is fixedly installed on the outer surface of the vertical rod. A movable sleeve is movably sleeved inside the fixing block. A sliding groove is opened on the outer surface of the vertical rod. A slider is slidably connected inside the sliding groove. An insert rod is fixedly installed on the outer surface of the slider.

[0008] As a preferred embodiment of this utility model, a bidirectional screw is movably sleeved inside the vertical rod, the outer surface of the bidirectional screw is threaded into the inner surface of the slider, and a screwing block is fixedly installed at the top end of the bidirectional screw.

[0009] As a preferred embodiment of this utility model, a base is fixedly installed at the bottom of the column, and a reinforcing rod is fixedly installed at the top of the base. The end of the reinforcing rod away from the base is fixedly connected to the outer surface of the column.

[0010] As a preferred technical solution of this utility model, a first telescopic rod and a second telescopic rod are fixedly installed on the outer surface of the vertical rod. The outer surface of the first telescopic rod is movably connected with the interior of the column and the connecting rod. The outer surface of the second telescopic rod is movably connected with the interior of the column and the round rod. A slot is provided at the top of the first telescopic rod.

[0011] As a preferred embodiment of this utility model, a circular block is fixedly installed at the top of the column, a lever is slidably connected inside the circular block, a moving rod is fixedly installed at the bottom of the lever, the outer surface of the moving rod is movably sleeved with the inside of the column, and the bottom end of the moving rod is inserted into the inside of the slot.

[0012] As a preferred embodiment of this utility model, a spring is fixedly installed at the top of the paddle, and the top of the spring is fixedly connected to the inside of the circular block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This type of protective support for construction projects allows for initial connection simply by fitting the connecting block into the movable sleeve during assembly. Subsequently, by turning the turning block, a bidirectional screw is driven to rotate, causing the insertion rod to simultaneously insert into the aligned holes of the connecting block and the movable sleeve, quickly achieving a stable connection between the supports. This significantly simplifies the installation process and shortens operation time. Simultaneously, the movable sleeve and fixed block's sliding connection structure allows operators to flexibly adjust the connection angle of adjacent supports according to the actual layout requirements of the construction site. This effectively solves the adaptation problem of traditional fixed-angle supports in complex scenarios, significantly improving the versatility and practicality of the protective support in different construction environments, and providing an efficient solution for the rapid construction and personalized layout of protective structures in construction projects.

[0015] 2. This type of construction engineering protective bracket achieves flexible lateral extension of the bracket's protective length through a telescopic and locking structure. When it is necessary to expand the protective range, the operator only needs to move the lever to disengage the moving rod from the slot of the first telescopic rod, thereby releasing the overall locking of the telescopic rod. Then, pulling the vertical rod causes the first and second telescopic rods to extend outward simultaneously. The operation is simple and convenient, requiring no complicated tools or professional skills, and greatly improving construction efficiency. In addition, multiple slots with the same spacing, together with the moving rod, can precisely adjust the protective length to adapt to the needs of different engineering scenarios. The spring reset design ensures that the locked state can be quickly restored after unlocking. Furthermore, the roller design enhances structural stability, ensuring the overall stability and reliability of the bracket while extending the protective length, effectively improving the practicality and safety of construction engineering protection.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figs. 1 to 4 As shown, this utility model provides a protective support for building engineering, comprising:

[0023] Column 1, with connecting rod 2 and round rod 3 fixedly installed on the outer surface of column 1, and connecting block 4 fixedly installed on one side of column 1;

[0024] The assembly mechanism is located on the outer surface of column 1;

[0025] The assembly mechanism includes a vertical rod 5, the outer surface of which is in contact with the outer surface of the column 1. A roller 14 is fixedly installed at the bottom end of the vertical rod 5. A fixing block 6 is fixedly installed on the outer surface of the vertical rod 5. A movable sleeve 7 is movably sleeved inside the fixing block 6. A sliding groove 9 is opened on the outer surface of the vertical rod 5. A slider 10 is slidably connected inside the sliding groove 9. An insert rod 11 is fixedly installed on the outer surface of the slider 10.

[0026] This section clarifies the basic architecture of the protective bracket and the core components of the assembly mechanism. The column 1 serves as the main support structure, and the connecting rod 2 and the round rod 3 fixed on the outer surface constitute the basic protective frame. The connecting block 4 is fixed to one side of the column 1. During docking, the operator puts the connecting block 4 inside the movable sleeve 7 on another bracket to complete the docking with the adjacent bracket. The movable sleeve design of the fixed block 6 and the movable sleeve 7 allows the adjacent brackets to be flexibly rotated and the connection angle adjusted after the initial docking, adapting to complex scenarios such as building corners and slopes. The cooperation of the slide groove 9, the slider 10 and the insertion rod 11 provides a mechanical linkage basis for locking the splicing angle in the future. When the two sliders 10 move in opposite directions along the inside of the slide groove 9, they will drive the two insertion rods 11 to move in opposite directions. Then, the two insertion rods 11 will be precisely inserted into the alignment holes of the connecting block 4 and the movable sleeve 7 to achieve the limit locking of the connecting block 4 and the movable sleeve 7, thereby completing the connection between the two brackets.

[0027] The vertical rod 5 is internally fitted with a bidirectional screw 12, the outer surface of which is threaded into the inner surface of the slider 10, and a screwing block 13 is fixedly installed at the top of the bidirectional screw 12.

[0028] This section supplements the power transmission structure of the assembly mechanism. The bidirectional screw 12 passes through the interior of the vertical rod 5, and its outer surface is threadedly connected to the slider 10. The top screw block 13 is used for manual drive. When the operator rotates the screw block 13, the positive and negative thread structure of the bidirectional screw 12 can simultaneously drive the sliders 10 on both sides to move in opposite directions or towards each other along the slide groove 9, thereby driving the insertion rod 11 to accurately insert or disengage from the alignment hole of the connecting block 4 and the movable sleeve 7. This structure converts the manual rotation force into the linear motion of the slider 10, realizing the rapid locking and unlocking of the splicing angle, avoiding the cumbersome operation of traditional manual pins, and improving assembly efficiency.

[0029] The bottom of the column 1 is fixedly installed with a base 15, and the top of the base 15 is fixedly installed with a reinforcing rod 16. The end of the reinforcing rod 16 away from the base 15 is fixedly connected to the outer surface of the column 1.

[0030] This section strengthens the stable support structure of the bracket. The base 15 is fixed to the bottom of the column 1 and is used to connect with the building ground or foundation structure to provide foundation bearing capacity. The two ends of the reinforcing rod 16 are connected to the base 15 and the column 1 respectively. Through the principle of triangular stability, the anti-overturning ability of the column 1 is enhanced, ensuring the stability of the overall structure under complex working conditions.

[0031] The outer surface of the vertical rod 5 is fixedly equipped with a first telescopic rod 17 and a second telescopic rod 19. The outer surface of the first telescopic rod 17 is movably connected to the interior of the column 1 and the connecting rod 2. The outer surface of the second telescopic rod 19 is movably connected to the interior of the column 1 and the round rod 3. The top end of the first telescopic rod 17 is provided with a slot 18.

[0032] This section reveals the core structure for extending the lateral protection length. The first telescopic rod 17 and the second telescopic rod 19, which are fixed to the outer surface of the vertical rod 5, are respectively movably connected to the inside of the column 1 and the connecting rod 2 and the round rod 3, forming a telescopic linkage system. When the operator pulls the vertical rod 5, the two sets of telescopic rods extend outward synchronously, expanding the protection range.

[0033] The top of the column 1 is fixedly installed with a round block 20, and a paddle 21 is slidably connected inside the round block 20. The bottom end of the paddle 21 is fixedly installed with a moving rod 22. The outer surface of the moving rod 22 is movably connected to the inside of the column 1, and the bottom end of the moving rod 22 is inserted into the inside of the slot 18.

[0034] This section improves the locking mechanism of the telescopic rod. When the moving rod 22 is inserted into the slot 18, the first telescopic rod 17, the vertical rod 5 and the second telescopic rod 19 will be locked together by mechanical locking. When the lever 21 is pushed upward, the moving rod 22 will disengage from the slot 18 of the first telescopic rod 17, unlocking the rod and allowing it to extend and retract freely.

[0035] Among them, a spring 8 is fixedly installed at the top of the paddle 21, and the top of the spring 8 is fixedly connected to the inside of the round block 20.

[0036] This section reveals the source of the reset power for the moving lever 22. The spring 8 is fixed between the top of the paddle 21 and the inside of the round block 20. When the paddle 21 moves upward, the spring 8 is compressed and stores elastic potential energy. After the paddle 21 is released, the spring 8 releases its potential energy to push the paddle 21 and the moving lever 22 to automatically reset.

[0037] Working principle and usage process of this utility model:

[0038] When assembling the brackets, first bring the two brackets to be assembled close together, and insert the connecting block 4 on one bracket into the movable sleeve 7 on the other bracket to initially align and position the two brackets. Since the movable sleeve 7 is movably connected to the fixed block 6, the brackets to be assembled can be manually rotated according to the on-site building structure, such as corners and slopes, to flexibly adjust the connection angle between the two brackets to meet the protection layout requirements, thus solving the problem of fixed connection angle of traditional brackets. Then, the operator rotates the screw block 13 by hand, which drives the bidirectional screw 12 below it to rotate synchronously. The positive and negative thread design of the bidirectional screw 12 drives the two sliders 10 to move in opposite directions along the inside of the slide groove 9 when it rotates. At this time, the sliders 10 will drive the two insert rods 11 to move in opposite directions, and then accurately insert them into the alignment holes of the connecting block 4 and the movable sleeve 7. After the insert rods 11 are inserted, they block the relative movement of the connecting block 4 and the movable sleeve 7, firmly locking and fixing the two brackets to ensure the stability of the assembled bracket structure.

[0039] When it is necessary to expand the protection range by extending the lateral protection length, the operator moves the lever 21 upwards. The upward movement of the lever 21 causes the fixedly connected moving rod 22 to move upwards as well. At this time, the spring 8 will be compressed. Due to the design of the spring 8, it will have a good restoring effect on the overall movement of the lever 21. When the bottom of the moving rod 22 disengages from the inside of the slot 18 during movement, it will release the lock on the first telescopic rod 17. After unlocking, the operator holds the vertical rod 5 and pulls it outwards. Since the first telescopic rod 17 is fixedly connected to the vertical rod 5 and the second telescopic rod 19 is fixedly connected to the round rod 3, pulling the vertical rod 5 will cause the first telescopic rod 17 and the second telescopic rod 19 to extend outwards from the bracket simultaneously. The roller 14 contacts the ground and uses rolling friction to greatly reduce pulling resistance, making operation more labor-saving. A single person can easily complete the extension. The roller 14 can also provide good support for the entire vertical rod 5. When the telescopic rod is extended to the required length (the slots 18 on the first telescopic rod 17 are evenly spaced and can be positioned according to the requirements), the operator releases the lever 21. At this time, the spring 8 will drive the moving rod 22 to return downward through the lever 21, so that the bottom end of the moving rod 22 is inserted into the corresponding slot 18, and the position of the telescopic rod is relocked. At this time, the first telescopic rod 17, the second telescopic rod 19 and the vertical rod 5 can extend the protection range of the bracket to meet the diverse protection needs of construction projects.
