Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a safety springboard for building construction. Background Art

[0002] A construction safety springboard usually refers to a temporary step or walkway used to provide an aerial work platform at the construction site. It is designed to ensure the safety of workers' walking and avoid falls and other accidents. The use of safety springboards is an important part of building safety regulations, especially in high-altitude work scenarios such as scaffolding construction, roof operations, and bridge construction.

[0003] However, the prior art has the following disadvantages when used: the existing construction safety springboard hooks and external steel pipes are constructed, which is convenient and quick to operate, but the anti-slip effect between the hooks and the steel pipes is general, which is not conducive to improving the stability of the construction safety springboard and the steel pipe when they are placed. In addition, the existing construction safety springboard is provided with a platform for placing tools, but the platform for placing tools will cause the volume of the construction safety springboard to change, which will occupy a large space and make the construction safety springboard inconvenient to transport. Therefore, a construction safety springboard is urgently needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the existing construction safety springboard hooks and external steel pipes are used to build the existing construction safety springboard, which is convenient and quick to operate, but the anti-slip effect between the hooks and the steel pipes is general, which is not conducive to improving the stability of the construction safety springboard and the steel pipes when they are placed. In addition, the existing construction safety springboard is provided with a platform for placing tools, but the platform for placing tools will cause the volume of the construction safety springboard to change, which will occupy a large space and make the construction safety springboard inconvenient to transport.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a construction safety springboard, comprising: a board body, wherein a plurality of rectangular iron bars are fixedly installed on the inner circle of the board body, and further comprising:

[0006] Four hooks are fixedly mounted at both ends of the plate body, and two receiving slots are provided at one end of the plate body close to the hooks;

[0007] Two U-shaped blocks are respectively slidably mounted on the inner walls of the two receiving grooves, and the opposite ends of the two U-shaped blocks are rotatably mounted with limit hooks;

[0008] Two slide grooves are respectively provided at one end of the two limit hooks away from the U-shaped block, and the inner walls of the two slide grooves are both slidably mounted with sliding rods;

[0009] The two extension rods are respectively fixedly mounted on one end of the two U-shaped blocks located at the receiving grooves, and the two extension rods have limiting holes on one end located inside the plate body.

[0010] Preferably, two limiting rods are slidably mounted on one end of the plate body close to the extension rod, and elastic members are fixedly mounted on one end of the two limiting rods away from the extension rod.

[0011] The technical effect of adopting the above further scheme is that there are gaps between the multiple rectangular iron bars in the plate body, so that when the staff members step on the shoes, the bottoms of the shoes are squeezed to deform the shoes, thereby enhancing the friction with the shoes and preventing the staff members from sliding on the plate body and the rectangular iron bars. When the staff members hang the hooks on the external steel pipes that are horizontally parallel to the short sides of the plate body, the limit hooks are flipped from the U-shaped block, so that the slide groove at one end of the limit hook and the sliding rod are away from the U-shaped block, and the sliding rod is extended from the slide groove due to the influence of gravity but does not fall, which is convenient for extending the limit hook. The total length of one end of the positioning hook makes it convenient for the limiting hook to hook the external steel pipe that is horizontally parallel to the long side of the plate body. The staff pulls the limiting rod to stretch the elastic part to make one end of the limiting rod come out of the limiting hole, and the limiting rod no longer restricts the extension rod. Then, the limiting hook is pulled to drive the U-shaped block to slide on the inner wall of the storage groove, and the extension rod is pulled out from the inside of the plate body, which is convenient for extending the limiting hook, thereby adapting to steel pipes in different positions, which is beneficial to multi-directional restriction of the plate body, preventing the plate body from sliding with the external steel pipe, and further improving the stability of the plate body when placed.

[0012] Preferably, one end of the two elastic members close to the extension rod is fixedly mounted on one end of the plate body, and one end of the two limiting rods located inside the plate body is slidably connected to the inner wall of the limiting hole.

[0013] The technical effect of adopting the above further solution is: the staff pulls the limit rod to stretch the elastic member, so that one end of the limit rod comes out of the limit hole, and the limit rod no longer restricts the extension rod.

[0014] Preferably, a bidirectional threaded rod is rotatably mounted on one end of the plate body close to the hook, and threaded blocks are threadedly mounted on both ends of the bidirectional threaded rod.

[0015] The technical effect of adopting the above further solution is that the two ends of the bidirectional threaded rod are threaded with the two threaded blocks, so that when the bidirectional threaded rod is rotated, the two threaded blocks are driven to move.

[0016] Preferably, one end of the two threaded blocks away from the bidirectional threaded rod is slidably mounted on one end of the plate body, and one end of the two threaded blocks away from the plate body is rotatably mounted with a connecting rod.

[0017] The technical effect of adopting the above further solution is that the threaded block is slidably installed with the plate body, which is convenient for limiting the threaded block so that it cannot rotate with the bidirectional threaded rod, thereby improving the stability of the threaded block when moving.

[0018] Preferably, a connecting block is rotatably mounted on one end of the two connecting rods away from the threaded block, and an embedding groove is formed on one end of the two connecting blocks close to the bidirectional threaded rod.

[0019] The technical effect of adopting the above further solution is: when the two connecting rods move, they drive the two connecting blocks to move toward the plate body, and when the connecting blocks move, they drive the embedded grooves to move, and the embedded grooves move to contact the outer surface of the bidirectional threaded rod.

[0020] Preferably, a T-shaped block is fixedly mounted on one end of the two connecting blocks away from the embedding groove, and a placement plate is provided on one end of the two connecting blocks close to the T-shaped block.

[0021] The technical effect of adopting the above further solution is: when the connecting block moves, it drives the T-shaped block to move, and when the T-shaped block moves, it drives the placement plate to move towards the plate body.

[0022] Preferably, two T-shaped grooves are provided at one end of the placement plate close to the connection block, and the outer surfaces of the two T-shaped blocks are slidably connected to the inner walls of the two T-shaped grooves respectively.

[0023] The technical effect of adopting the above further solution is: the staff pushes the placement plate from the end of the placement plate away from the plate body, so that the T-shaped groove slides on the T-shaped block.

[0024] Compared with the prior art, the advantages and positive effects of the utility model are:

[0025] 1. In the utility model, when in use, the limit rod no longer limits the extension rod, and then the limit hook is pulled to drive the U-shaped block to slide on the inner wall of the storage groove, and the extension rod is pulled out from the inside of the plate body, which is convenient for extending the limit hook, thereby adapting to steel pipes in different positions, which is beneficial to multi-directional restriction of the plate body, preventing the plate body from sliding with the external steel pipe, and further improving the stability of the plate body when placed.

[0026] 2. In the utility model, when in use, the embedded groove moves to contact the outer surface of the bidirectional threaded rod, and when the outer surface of the placement plate fits with the outer surface of the plate body, the staff pushes the placement plate from the end of the placement plate away from the plate body to make the T-shaped groove slide on the T-shaped block, which is convenient for moving the placement plate to the top of the plate body, thereby greatly reducing the volume of the utility model, helping to reduce the space occupied and facilitating transportation.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0034] Embodiment 1, as Figure 1 - Figure 4 As shown, the utility model provides a safety springboard for construction, comprising: a board body 1, a plurality of rectangular iron bars 2 are fixedly installed on the inner circle of the board body 1, and further comprising:

[0035] Four hooks 3 are fixedly mounted on both ends of the plate body 1, and two receiving grooves 4 are formed at one end of the plate body 1 close to the hooks 3;

[0036] Two U-shaped blocks 5 are respectively slidably mounted on the inner walls of the two receiving grooves 4, and the opposite ends of the two U-shaped blocks 5 are both rotatably mounted with limit hooks 6;

[0037] Two slide grooves 7 are respectively provided at one end of the two limit hooks 6 away from the U-shaped block 5, and the inner walls of the two slide grooves 7 are slidably mounted with sliding rods 8;

[0038] The two extension rods 9 are respectively fixedly mounted on one end of the two U-shaped blocks 5 located at the receiving groove 4 , and the two extension rods 9 have a limiting hole 901 formed on one end located inside the plate body 1 .

[0039] In this embodiment, when in use, there are gaps between the multiple rectangular iron bars 2 in the plate body 1, so that when the staff members step on the shoes, the bottom of the shoes are squeezed to deform the shoes, thereby enhancing the friction with the shoes and preventing the staff members from sliding on the plate body 1 and the rectangular iron bars 2. When the staff members hang the hooks 3 on the external steel pipes that are transversely parallel to the short sides of the plate body 1, the limiting hooks 6 are flipped out of the U-shaped block 5, so that the slide groove 7 and the sliding rod 8 at one end of the limiting hook 6 are away from the U-shaped block 5, and the sliding rod 8 is extended from the slide groove 7 due to the influence of gravity but does not fall, so as to extend the total length of one end of the limiting hook 6. , so that the limiting hook 6 can hook the external steel pipe that is horizontally parallel to the long side of the plate body 1. The staff pulls the limiting rod 108 to stretch the elastic member 109, so that one end of the limiting rod 108 comes out of the limiting hole 901, and the limiting rod 108 no longer restricts the extension rod 9. Then, the limiting hook 6 is pulled to drive the U-shaped block 5 to slide on the inner wall of the storage groove 4, and the extension rod 9 is pulled out from the inside of the plate body 1, so as to extend the limiting hook 6, thereby adapting to the steel pipes in different positions, which is beneficial to multi-directional restriction of the plate body 1, preventing the plate body 1 from sliding with the external steel pipe, and further improving the stability of the plate body 1 when placed.

[0040] Embodiment 2, as Figure 1 - Figure 4 As shown, two limiting rods 108 are slidably installed at one end of the plate body 1 close to the extension rod 9, and elastic members 109 are fixedly installed at one end of the two limiting rods 108 away from the extension rod 9. The two elastic members 109 are fixedly installed at one end of the plate body 1 close to the extension rod 9. The ends of the two limiting rods 108 located inside the plate body 1 are slidably connected to the inner wall of the limiting hole 901. A two-way threaded rod 101 is rotatably installed at one end of the plate body 1 close to the hook 3. Thread blocks 102 are threadedly installed at both ends of the two-way threaded rod 101. The two thread blocks 102 are slidably installed at one end of the plate body 1 away from the end of the two-way threaded rod 101. A connecting rod 103 is rotatably installed on the end of the block 102 away from the plate body 1, and a connecting block 104 is rotatably installed on the end of the two connecting rods 103 away from the threaded block 102. An embedding groove 105 is provided on the end of the two connecting blocks 104 close to the bidirectional threaded rod 101, and a T-shaped block 106 is fixedly installed on the end of the two connecting blocks 104 away from the embedding groove 105. A placing plate 10 is provided on the end of the two connecting blocks 104 close to the T-shaped block 106, and two T-shaped grooves 107 are provided on the end of the placing plate 10 close to the connecting block 104, and the outer surfaces of the two T-shaped blocks 106 are slidably connected to the inner walls of the two T-shaped grooves 107 respectively.

[0041] When the two connecting rods 103 move, they drive the two connecting blocks 104 to move toward the direction of the plate body 1. When the connecting block 104 moves, it drives the embedded groove 105 and the T-shaped block 106 to move. When the T-shaped block 106 moves, it drives the placement plate 10 to move toward the plate body 1. When the embedded groove 105 moves to contact the outer surface of the two-way threaded rod 101, the outer surface of the placement plate 10 is in contact with the outer surface of the plate body 1, and the staff pushes the placement plate 10 from the end of the placement plate 10 away from the plate body 1, so that the T-shaped groove 107 slides on the T-shaped block 106, so as to facilitate the placement plate 10 to be moved above the plate body 1, thereby greatly reducing the volume of the utility model, which is conducive to reducing the occupied space and facilitating transportation.

[0042] Working principle: When in use, there are gaps between the multiple rectangular iron bars 2 in the plate body 1, so that when the staff step on the shoes, the bottom of the shoes are squeezed to deform the shoes, thereby enhancing the friction with the shoes and preventing the staff from sliding on the plate body 1 and the rectangular iron bars 2. When the staff hangs the hook 3 on the external steel pipe that is horizontally parallel to the short side of the plate body 1, the limit hook 6 is flipped from the U-shaped block 5, so that the slide groove 7 and the sliding rod 8 at one end of the limit hook 6 are away from the U-shaped block 5, and the sliding rod 8 is extended from the slide groove 7 under the influence of gravity but The limiting hook 6 will not fall off, so it is convenient to extend the total length of one end of the limiting hook 6, so that the limiting hook 6 hooks the external steel pipe that is horizontally parallel to the long side of the plate body 1. The staff pulls the limiting rod 108 to stretch the elastic member 109, so that one end of the limiting rod 108 comes out of the limiting hole 901, and the limiting rod 108 no longer restricts the extension rod 9. Then, the limiting hook 6 is pulled to drive the U-shaped block 5 to slide on the inner wall of the storage groove 4, and the extension rod 9 is pulled out from the inside of the plate body 1, so as to extend the limiting hook 6, thereby adapting to steel pipes in different positions, which is conducive to multiple adjustment of the plate body 1. Directional restriction prevents the plate body 1 from sliding with the external steel pipe, further improving the stability of the plate body 1 when placed. When in use, the two-way threaded rod 101 is rotated to drive the two threaded blocks 102 to move relatively close to one end of the plate body 1. When the two threaded blocks 102 move, they drive the two connecting rods 103 to move, so that the two connecting rods 103 are gradually parallel to the plate body 1. When the two connecting rods 103 move, they drive the two connecting blocks 104 to move toward the plate body 1. When the connecting blocks 104 move, they drive the embedded grooves 105 and the T-shaped blocks 106 moves, and when the T-shaped block 106 moves, it drives the placement plate 10 to move toward the plate body 1, and the embedded groove 105 moves to contact the outer surface of the two-way threaded rod 101. When the outer surface of the placement plate 10 is in contact with the outer surface of the plate body 1, the staff pushes the placement plate 10 from the end of the placement plate 10 away from the plate body 1 to make the T-shaped groove 107 slide on the T-shaped block 106, which is convenient for moving the placement plate 10 to the top of the plate body 1, thereby greatly reducing the volume of the utility model, which is beneficial to reducing the occupied space and facilitating transportation.
