Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a scaffolding connection structure for building construction. Background Technology

[0002] Scaffolding is a working platform erected to ensure the smooth progress of various construction processes. In existing technology, scaffolding connections are mainly made through various fasteners and screws. When connecting support rods and horizontal bars, multiple screws are used to fix them in order to ensure the firmness between the horizontal bars and support rods. Therefore, during construction, the screws need to be tightened repeatedly, which not only takes a lot of time and greatly reduces work efficiency, but also makes it easy for screws and fasteners to be lost, resulting in unstable fixing effect. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art and provide a scaffolding connection structure for building construction, which ensures the firmness of the connection between the horizontal connecting pipe and the vertical connecting pipe, saves installation time, and improves work efficiency.

[0004] To achieve the above technical effects, this utility model provides a scaffolding connection structure for building construction, which includes:

[0005] A cross-shaped connecting rod includes transverse and longitudinal support rods connected in a cross shape;

[0006] A longitudinal connecting pipe is detachably connected to the longitudinal support rod. Two trapezoidal fixing blocks are symmetrically installed at the ends of the longitudinal connecting pipe. The longitudinal support rod has a first cavity. Two first locking blocks are slidably installed between the two trapezoidal fixing blocks in the first cavity. Two first locking slots are respectively opened on the two trapezoidal fixing blocks for the corresponding first locking blocks to slide and engage. The ends of the longitudinal support rod are provided with a multi-directional elastic movement component for multi-directional turning during the process of the longitudinal connecting pipe being pressed down to connect with the longitudinal support rod, so as to drive the two first locking blocks to slide relative to each other and thus achieve engagement with the two first locking slots respectively.

[0007] A transverse connecting tube is detachably connected to the transverse support rod. A fixing rod is fixedly connected to the end of the transverse support rod. A sleeve is fixedly fitted on the side of the fixing rod that is relatively away from the transverse support rod, and a first truncated cone is slidably fitted on the side that is relatively close to the transverse support rod. Two second cavities are symmetrically provided on the inner wall of the transverse connecting tube, and two second locking blocks are provided in the two second cavities for sliding relative to each other during the process of the transverse connecting tube being translated to connect with the transverse support rod. The first end of the second cavities extends out of the corresponding second cavity and is locked between the first truncated cone and the sleeve, thereby realizing the connection between the transverse connecting tube and the transverse support rod.

[0008] Preferably, a crossbar is fixedly connected inside the first cavity, and two sliding plates are slidably sleeved on the crossbar. A first compression spring is fixedly connected between the opposite sides of the two sliding plates and the inner wall of the first cavity. The first compression spring is sleeved on the crossbar, and the ends of the two sliding plates are respectively fixedly connected to the corresponding first locking blocks.

[0009] Preferably, the longitudinal support rod has a groove in the middle, and the multi-directional elastic movement component includes a trapezoidal slider elastically disposed in the first cavity and for receiving two first blocks, and an L-shaped slider fixedly connected to the bottom of the trapezoidal slider. The longitudinal bar of the L-shaped slider passes through the side wall of the longitudinal support rod and extends into the groove, the transverse bar of the L-shaped slider is slidably installed in the groove, and a second compression spring is sleeved on the outer side of the L-shaped slider.

[0010] The trapezoidal slider has two pairs of inclined planes on each side, which are respectively connected to the first card block, to convert the downward pressing motion of the longitudinal connecting tube into a lateral outward motion.

[0011] Preferably, the sleeve is provided with a groove, and a third compression spring is fixedly connected between the first truncated cone and the inner wall of the groove, and the third compression spring is sleeved on the fixed rod.

[0012] Preferably, two second slots are symmetrically provided on the inner wall of the transverse connecting pipe, and the second slots are provided in a one-to-one correspondence with the second cavity. A square slide rod is fixedly connected to the second end of the second block. One end of the square slide rod facing away from the second block passes through the transverse connecting pipe and extends into the second slot, and a stop block is fixedly connected to the end. A fourth compression spring is fixedly connected between the second block and the inner side wall of the second cavity, and the fourth compression spring is sleeved on the outside of the square slide rod.

[0013] Preferably, the elastic force of the second compression spring is greater than that of the first compression spring, and the elastic force of the fourth compression spring is greater than that of the third compression spring.

[0014] Preferably, the longitudinal connecting pipe is provided with a slot for inserting and connecting the longitudinal support rod.

[0015] Preferably, a second frustum is fixedly connected to the side of the sleeve opposite to the first frustum, and the second frustum is sleeved and fixed on the fixed rod.

[0016] The technical effects achieved by this utility model due to the adoption of the above technical solution are as follows:

[0017] 1) With the fourth compression spring, it is convenient for the second locking block to slide into and out of the second cavity. When the second locking block extends between the sleeve and the first truncated cone, the second locking block can effectively lock the transverse connecting pipe onto the fixed rod, and the sleeve effectively supports the transverse connecting pipe.

[0018] 2) By applying external force, the two L-shaped sliding rods and the trapezoidal slider move closer to the center. At this time, under the force of the first compression spring, the first locking block moves into the first cavity. This makes it easy to put the trapezoidal fixing block and the longitudinal connecting tube onto the longitudinal support of the cross connecting rod. Then, the external force is released, and under the force of the second compression spring, the first locking block slides into the first slot, effectively locking and fixing the trapezoidal fixing block onto the two longitudinal support rods on the cross connecting rod.

[0019] 3) It ensures the firmness of the connection between the horizontal and vertical connecting pipes, saves a lot of installation time, and improves work efficiency. Attached Figure Description

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.

[0030] Please see Figures 1 to 6 As shown, this utility model embodiment provides a scaffolding connection structure for building construction, including a cross connecting rod 1, a longitudinal connecting pipe 22, and a transverse connecting pipe 21. The cross connecting rod 1 includes a transverse support rod 101 and a longitudinal support rod 102 connected in a cross shape. The longitudinal connecting pipe 22 is detachably connected to the longitudinal support rod 102. Two trapezoidal fixing blocks 23 are symmetrically installed at the ends of the longitudinal connecting pipe 22. The longitudinal support rod 102 is provided with a first cavity 2. Two first locking blocks 4 are slidably installed between the two trapezoidal fixing blocks 23 in the first cavity 2. Two first locking slots 20 are respectively opened on the two trapezoidal fixing blocks 23 for the corresponding first locking blocks 4 to slide and engage. The ends of the longitudinal support rod 102 are provided with a multi-directional elastic movement component for multi-directional turning during the process of the longitudinal connecting pipe 22 being pressed down to connect with the longitudinal support rod 102, so as to drive the two first locking blocks 4 to slide relative to each other and thus engage with the two first locking slots 20 respectively.

[0031] Furthermore, the transverse connecting pipe 21 is detachably connected to the transverse support rod 101. A fixing rod 12 is fixedly connected to the end of the transverse support rod 101. A sleeve 10 is fixedly sleeved on the side of the fixing rod 12 that is relatively far away from the transverse support rod 101, and a first frustum 11 is slidably sleeved on the side that is relatively close to the transverse support rod 101. Two second cavities 16 are symmetrically provided on the inner wall of the transverse connecting pipe 21. Two second locking blocks 15 are provided in the two second cavities 16 for sliding relative to each other during the process of the transverse connecting pipe 21 being translated to connect with the transverse support rod 101. The first end extends out of the corresponding second cavity 16 and is locked between the first frustum 11 and the sleeve 10, thereby realizing the connection between the transverse connecting pipe 21 and the transverse support rod 101.

[0032] Please see Figure 1 and Figure 5 As shown, a crossbar 3 is fixedly connected inside the first cavity 2. Two sliding plates 6 are slidably mounted on the crossbar 3. A first compression spring 7 is fixedly connected between the opposite sides of the two sliding plates 6 and the inner wall of the first cavity 2. The first compression spring 7 is mounted on the crossbar 3, and the ends of the two sliding plates 6 are respectively fixedly connected to the corresponding first locking blocks 4. Preferably, a groove 25 is provided in the middle of the longitudinal support rod 102. The multi-directional elastic movement assembly includes a trapezoidal slider 5 elastically disposed in the first cavity 2 and for receiving the two first locking blocks 4, and an L-shaped slider 9 fixedly connected to the bottom of the trapezoidal slider 5. The longitudinal rod of the L-shaped slider 9 passes through the side wall of the longitudinal support rod 102 and extends into the groove 25. The crossbar of the L-shaped slider 9 is slidably installed in the groove 25. A second compression spring 8 is mounted on the outer side of the L-shaped slider 9.

[0033] In this embodiment, the trapezoidal slider 5 has two pairs of inclined surfaces on each side of its corresponding first locking block 4, forming two pairs of inclined surfaces to convert the downward pressing motion of the longitudinal connecting pipe 102 into a lateral outward motion. It should be noted that in this embodiment, the longitudinal connecting pipe 22 is provided with slots 26 for inserting and connecting the longitudinal support rod 102.

[0034] Furthermore, in this embodiment, a second frustum 13 is fixedly connected to the side of the sleeve 10 opposite to the first frustum 11, and the second frustum 13 is fixedly sleeved on the fixing rod 12. The sleeve 10 is provided with a groove 24, and a third compression spring 14 is fixedly connected between the first frustum 11 and the inner wall of the groove 24, and the third compression spring 14 is sleeved and installed on the fixing rod 12.

[0035] Furthermore, two second slots 27 are symmetrically provided on the inner wall of the transverse connecting pipe 21. The second slots 27 are arranged one-to-one with the second cavities 16. A square slide rod 18 is fixedly connected to the second end of the second locking block 15. The end of the square slide rod 18 facing away from the second locking block 15 passes through the transverse connecting pipe 21 and extends into the second slot 27, and a stop block 19 is fixedly connected to the end. A fourth compression spring 17 is fixedly connected between the second locking block 15 and the inner wall of the second cavity 16, and the fourth compression spring 17 is sleeved on the outside of the square slide rod 18. It should be noted that in this embodiment, the elastic force of the second compression spring 8 is much greater than that of the first compression spring 7, and the elastic force of the fourth compression spring 17 is much greater than that of the third compression spring 14.

[0036] The working principle of the scaffolding connection structure for building construction according to this utility model embodiment includes:

[0037] When connecting the transverse connecting pipe 21, the transverse connecting pipe 21 is fitted onto the second frustum 13 and the sleeve 10 and slid towards the first frustum 11. During this process, the inclined surface of the second locking block 15 provided on the transverse connecting pipe 21 first contacts the inclined surface of the second frustum 13, and then the second locking block 15 is pushed into the second cavity 16. After the second locking block 15 slides past the sleeve 10, under the force of the fourth compression spring 17, the second locking block 15 slides out of the second cavity 16 again and extends between the sleeve 10 and the first frustum 11. At this time, the transverse connecting pipe 21 can be effectively locked onto the fixing rod 12 by the second locking block 15, and the sleeve 10 effectively supports the transverse connecting pipe 21.

[0038] When connecting the longitudinal connecting pipe 22, under the action of external force, the two L-shaped sliding rods 9 drive the trapezoidal slider 5 to move closer to the middle of the cross connecting rod 1. At this time, under the force of the first compression spring 7, the slide plate 6 slides on the cross bar 3, thereby causing the two first locking blocks 4 to move into the first cavity 2. At this time, the first locking blocks 4 are in the position as follows: Figure 2 In the state shown, the trapezoidal fixing block 23 and the longitudinal connecting pipe 22, which are fixedly connected together, are then fitted onto the two longitudinal support rods 102 on the cross connecting rod 1. Then, the external force on the two L-shaped sliding rods 9 is released. Under the force of the second compression spring 8, the trapezoidal slider 5 slides towards the first locking block 4 until it engages with the two first locking blocks 4. The two first locking blocks 4 are then slid to both sides, causing the first locking blocks 4 to slide into the first locking groove 20, effectively locking and fixing the trapezoidal fixing block 23 onto the two longitudinal support rods 102 on the cross connecting rod 1. At this time, as shown... Figure 1 The state shown is as described above. Then, multiple directional connecting pipes 21 and longitudinal connecting pipes 22 are connected together sequentially in the same manner as described above, thereby constructing a scaffold. At this point, as shown... Figure 4 The state shown.

[0039] When disassembling the transverse connecting pipe 21, continue to move the transverse connecting pipe 21 closer to the center of the cross connecting rod 1, so that the inclined surface of the second locking block 15 on the transverse connecting pipe 21 contacts the first truncated cone 11. Then, push the second locking block 15 into the second cavity 16. When the second locking block 15 slides to the middle of the first truncated cone 11, under the force of the fourth compression spring 17, the second locking block 15 slides out of the second cavity 16 again and contacts the inclined surface of the first truncated cone 11. Then, pull the transverse connecting pipe 21 to both sides. Then, under the action of the fourth compression spring 17, the second locking block 15 drives the first truncated cone 11 to slide synchronously to both sides until the first truncated cone 11 contacts the sleeve 10. At this time, if Figure 3 In the state shown, the second locking block 15 is then pushed into the second cavity 16 again, so that the second locking block 15 slides over the sleeve 10 and the second frustum 13. At this time, its transverse connecting tube 21 can be removed from the sleeve 10, the second frustum 13 and the fixing rod 12.

[0040] When the longitudinal connecting rod 22 is removed, external force is applied again to cause the two L-shaped sliding rods 9 to move the trapezoidal slider 5 closer to the center of the cross connecting rod 1. At this time, under the force of the first compression spring 7, the slide plate 6 slides on the crossbar 3, thereby causing the two first locking blocks 4 to move into the first cavity 2. At this time, the first locking blocks 4 are once again in the same position as before. Figure 2 As shown in the diagram, the longitudinal connecting rod 22 can then be directly removed from the cross connecting rod 1.

[0041] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
