This device has a simple structure and effectively utilizes a threaded clamping structure to extend the keel rods and achieve middle overlap, exhibiting good practicality and economy, which is beneficial for the promotion and use of the equipment.

Description

Technical Field

[0001] This utility model relates to the technical field of construction auxiliary materials, specifically to a keel frame that can be quickly disassembled and assembled. Background Technology

[0002] During construction, keel frames are widely used in infrastructure construction due to their relatively light weight and high support capacity. However, if the keel frame is too short during construction, it needs to be welded to make up for it, which is inefficient and affects the strength. In addition, facilities built using keel frames usually have a short service life, and welding is not conducive to disassembly of equipment. Furthermore, there is also a need for lateral connections during facility construction, requiring a keel frame that can be quickly assembled and disassembled for easy installation. Utility Model Content

[0003] In order to solve the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a keel frame that can be connected laterally and extended longitudinally, while meeting the requirements of quick disassembly and assembly.

[0004] The technical solution adopted in this utility model is: a keel frame that can be quickly disassembled and assembled, including...

[0005] The keel frame pole includes a support plate, and two sets of support uprights are provided with connecting hook plates on opposite sides. The connecting hook plates have an "L" shaped cross-section, and one side of the connecting hook plate is fixedly connected to the side of the support uprights away from the support plate.

[0006] The connecting plate has a "C" shaped cross-section. The inner cavity of the connecting plate is fastened to the outer side of the supporting upright plate and the connecting hook plate. The two ends of the middle part of the connecting plate are provided with through holes. Fixing members are provided in the through holes. The fixing members are used to connect one end of the keel frame rod with the connecting plate.

[0007] In one embodiment, the fastener includes a screw that passes through the through hole. The fastener also includes an abutment plate disposed on the inner cavity side of the connecting plate near the supporting plate. The screw passes through and is rotatably connected to the middle of the abutment plate. The abutment plate has an arc-shaped chamfer on one diagonal. The two ends of the abutment plate abut against the opposite sides of the adjacent supporting plates.

[0008] In one embodiment, a washer is provided between the screw and the connecting plate.

[0009] In one embodiment, a support member is provided between the abutment plate and the connecting plate. The support member includes a support cylinder, the screw passes through but does not abut against the support cylinder, and both ends of the abutment plate pass through the inner cavity of the support cylinder.

[0010] In one embodiment, a limiting piece is provided between the support cylinder and the connecting plate. The length of the limiting piece is less than the distance between the two sets of connecting hook plates. The limiting piece is used to prevent the support cylinder from rotating between the two sets of connecting hook plates.

[0011] In one embodiment, the connecting plate further includes a transverse connector, which includes a connecting extension plate. The connecting extension plate is located in the middle of the side of the connecting plate away from the supporting plate. The cross-section of the connecting extension plate has the same "C" shape as the cross-section of the connecting plate. One end of the connecting extension plate is fixedly connected to the connecting plate. A connecting through hole is provided in the middle of the connecting extension plate. A fixing member is also provided in the middle of the connecting through hole. The end of the keel rod fixed by the connecting extension plate and the fixing member abuts against the connecting plate.

[0012] In one embodiment, the support cylinder and the limiting piece are made of plastic.

[0013] In one embodiment, the keel frame rod, the connecting plate, and the fastener are made of aluminum alloy.

[0014] The beneficial effects of this utility model are as follows: This utility model is a keel frame that can be connected laterally and extended longitudinally, while meeting the requirements for quick assembly and disassembly. The specific implementation method is as follows:

[0015] The operator first inserts one of the support cylinders on the connecting plate into the space between the two sets of connecting hook plates, so that the abutment plate abuts against one side of the connecting hook plate. The support cylinder helps the fixing parts on the connecting plate to be inserted between the two sets of connecting hook plates more quickly. Then, the screw is rotated. During the rotation of the screw, the abutment plate is fixed by the limiting plate of the connecting hook plate to prevent the abutment plate from rotating. As the screw is gradually rotated to reduce the distance between the abutment plates, the position where the abutment plate abuts against the support plate is an arc-shaped chamfer. The abutment plate and the connecting plate clamp the connecting hook plate to achieve the connection of the keel frame rod. At the same time, since the support cylinder is made of plastic, it cannot completely limit the rotation of the abutment plate. After the support cylinder breaks, the abutment surface of the side of the abutment plate turns from the arc-shaped chamfer to both ends, so as to achieve complete fixation. The other end is used in the same way to make the ends of the two sets of keel frame rods abut against each other and fix them, so as to achieve the extension of the keel frame rod.

[0016] If it is necessary to connect another set of keel frame rods in the middle of the keel frame rod, select a workpiece with a connecting extension plate on one side of the connecting plate. After the two sets of fixing pieces on the connecting plate are completely slid into the connecting hook plates in the keel frame rod, fix them in the manner described above. Then, use the fixing piece in the middle of the connecting extension plate to pass through the end of the other keel frame rod and abut against the connecting plate. Then, rotate the screw to fix it, and the lateral connection of the keel frame rods can be achieved.

[0017] The equipment has a simple structure and effectively utilizes the special structure of the keel frame rod in conjunction with the fasteners to complete the extension and connection of the keel frame rod. At the same time, it can realize the quick disassembly function, which has good practicality and economy, and is beneficial to the promotion and use of the equipment. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] The following is combined with Figure 1-5This invention describes a specific embodiment of a keel frame that can be quickly assembled and disassembled, comprising:

[0028] The keel frame pole 1 includes a support plate 11 and two sets of support uprights 12 with connecting hook plates 13 on opposite sides. The cross section of the connecting hook plate 13 has an "L" shape structure. One side of the connecting hook plate 13 is fixedly connected to the side of the support upright 12 away from the support plate 11, forming multiple bends to strengthen the support strength.

[0029] The connecting plate 2 has a "C" shaped cross-section. The inner cavity of the connecting plate 2 is fastened to the outer side of the supporting plate 12 and the connecting hook plate 13. The two ends of the middle part of the connecting plate 2 are provided with through holes 21. The through holes 21 are provided with fasteners 3. The fasteners 3 are used to connect one end of the keel frame rod 1 to the connecting plate 2. Specifically, the fasteners 3 include screws 31, which pass through the through holes 21. The fasteners 3 also include abutment plates 34. The abutment plates 34 are located on the inner cavity side of the connecting plate 2 near the supporting plate 11. The screws 31 pass through and are rotatably connected to the middle part of the abutment plates 34. One diagonal corner of the abutment plates 34 is provided with an arc-shaped chamfer 341. The two ends of the abutment plates 34 abut against the opposite sides of the adjacent supporting plates 12.

[0030] Beneficially, a washer 311 is provided between the screw 31 and the connecting plate 2;

[0031] Advantageously, a support member is provided between the abutment plate 34 and the connecting plate 2. The support member includes a support cylinder 32. The screw 31 passes through but does not abut against the support cylinder 32. Both ends of the abutment plate 34 pass through the inner cavity of the support cylinder 32. Advantageously, a limiting piece 33 is provided between the support cylinder 32 and the connecting plate 2. The length of the limiting piece 33 is less than the distance between the two sets of connecting hook plates 13. The limiting piece 33 is used to prevent the support cylinder 32 from rotating between the two sets of connecting hook plates 13. Specifically, the support cylinder 32 and the limiting piece 33 are made of plastic to support the abutment plate 34 and facilitate the insertion of the fixing member 3 between the connecting hook plates 13.

[0032] Beneficially, the connecting plate 2 also includes a transverse connecting member, which includes a connecting extension plate 4. The connecting extension plate 4 is located in the middle of the side of the connecting plate 2 away from the supporting plate 11. The cross-section of the connecting extension plate 4 has the same "C" shape as the cross-section of the connecting plate 2. One end of the connecting extension plate 4 is fixedly connected to the connecting plate 2. The connecting extension plate 4 has a connecting through hole 41 in the middle. The connecting through hole 41 also has a fixing member 3 in the middle. The end of the keel rod 1 fixed by the connecting extension plate 4 and the fixing member 3 abuts against the connecting plate 2.

[0033] Beneficially, the keel frame rod 1, connecting plate 2, and fastener 3 are made of aluminum alloy, which helps to reduce weight and increase strength.

[0034] Working principle of this utility model:

[0035] The operator first inserts one of the support cylinders 32 on the connecting plate 2 into the space between the two sets of connecting hook plates 13, so that the abutment plate 34 abuts against one side of the connecting hook plate 13. The support cylinder 32 can assist the fixing piece 3 on the connecting plate 2 to be inserted between the two sets of connecting hook plates 13 more quickly. Then, the screw 31 is rotated. During the rotation of the screw 31, the abutment plate 34 is fixed by the limiting piece 33 of the connecting hook plate 13, preventing the abutment plate 34 from rotating. As the screw 31 is gradually rotated to reduce the distance between the abutment plates 34, the abutment plate... The position of the abutment plate 34 abutting the support plate 12 is an arc-shaped chamfer 341. The abutment plate 34 and the connecting plate 2 clamp the connecting hook plate 13 to connect the keel frame rod 1. At the same time, since the support cylinder 32 is made of plastic, it cannot completely limit the rotation of the abutment plate 34. After the support cylinder 32 breaks, the abutment surface of the side of the abutment plate 34 turns from the arc-shaped chamfer 341 to both ends, which can achieve complete fixation. The other end adopts the same method so that the ends of the two sets of keel frame rods 1 abut against each other and are fixed, which can achieve the extension of the keel frame rod 1.

[0036] If it is necessary to connect another set of keel frame rods 1 in the middle of the keel frame rod 1, select a workpiece with a connecting extension plate 4 on one side of the connecting plate 2. After the two sets of fixing parts 3 on the connecting plate 2 are completely slid into the connecting hook plates 13 in the keel frame rod 1, fix them in the above manner. Then, use the fixing part 3 in the middle of the connecting extension plate 4 to pass through the end of the other keel frame rod 1 and abut against the connecting plate 2. Then rotate the screw 31 to fix it, and the lateral connection of the keel frame rods 1 can be realized.
