Description

Technical Field

[0001] The utility model relates to the technical field of template support frames, in particular to an adjustable horizontal rod and a template support frame. Background Art

[0002] At present, the commonly used formwork support frames in the engineering industry include sleeve-type scaffolding, bowl-type scaffolding, and disc-type scaffolding, and the length of the horizontal bars of these scaffoldings is 300mm. When setting up formwork support frames, it is often encountered that the distance between two vertical bars is non-standard. In this case, in order to meet the specifications and safety requirements, it is often necessary to rearrange the distance between the vertical bars, or use steel pipes as horizontal bars to connect with the vertical bars at both ends with fasteners, and the horizontal bars extend to both ends to buckle at least 2 vertical bars of the fixed bracket.

[0003] For example, the current standards for steel pipe scaffolding rods are all fixed modulus and distance. The horizontal rod is made of Q235B steel pipe with a diameter of 48mm and a wall thickness of 2.5mm. The length of the horizontal rod is set in multiples of 300mm. There are 6 lengths, and the horizontal rod models are: SG300, SG600, SG900, SG1200, SG1500, and SG1800. At present, for the non-300mm modulus of the horizontal bar spacing, the anomaly (triangular area, circular area) or non-rectangular area processing method, whether it is a work frame or a support frame, the main method is to use ordinary steel pipes and disc buckle vertical rods to connect at each step at the break of the frame, which serves as the horizontal rod function, and the horizontal steel pipes are connected to extend to both ends to buckle at least two vertical rods of the fixed bracket, and scissor braces are continuously set along the vertical direction of the frame.

[0004] This approach is not only complex to construct, but also difficult to operate in some areas with dense frames. It is easy to miss the horizontal rod, which affects the overall stability of the frame. It is not a matching standardized scaffolding component, and it is not easy to construct a geometrically invariant steel pipe support system. In the case of non-standard modules, the spacing of the vertical poles needs to be adjusted, which increases the difficulty of construction; steel pipes are used as horizontal rods and connected to the vertical poles at both ends with fasteners. At least 4 fasteners and 1 short steel pipe are required in each step of the vertical pole, which requires a large amount of materials and increases costs. Utility Model Content

[0005] The purpose of the utility model is to provide an adjustable horizontal rod and a template support frame, so as to at least solve one of the problems raised in the above-mentioned background technology.

[0006] The technical solution of the utility model is:

[0010] Furthermore, the threads of the screws at both ends of the tube body have opposite rotation directions, and the two screws can enter and exit the tube body at the same time.

[0011] Furthermore, one end of the screw rod close to the buckle joint is welded to the buckle joint.

[0012] Furthermore, the auxiliary adjustment handle is U-shaped.

[0018] Furthermore, the inner wall of the mounting portion elastically abuts against the outer wall of the vertical rod.

[0019] The utility model provides an adjustable horizontal rod and a template support frame through improvement, which has at least the following improvements and beneficial effects compared with the prior art:

[0020] 1.

In addition, the overall construction method of the horizontal rod of the utility model is similar to the construction method of the traditional scaffolding, so it is more convenient and safer to use. Whether in special-shaped, non-rectangular and insufficient modulus areas, by adjusting the length of the horizontal rod, the horizontal rod joint can be inserted into the installation plate and connected with a plug-in to form a steel pipe bracket with a structural geometry unchanged system, thereby ensuring the absolute stability and safe operation of the support frame during the construction process.

[0033] The utility model provides an adjustable horizontal rod and a template support frame through improvement. The technical solution of the utility model is:

[0034] like Figure 1 As shown,

[0035] An adjustable horizontal rod, comprising:

[0036] The tube body has screws threadedly connected at both ends of the tube body. The screws at both ends of the tube body have opposite thread directions, and the two screws can enter and exit the tube body at the same time. By providing the screw, the total length of the tube body and the screw can be changed when the tube body is rotated, and the overall length of the horizontal rod can be adjusted, that is, the length of the horizontal rod can be freely adjusted. It breaks through the limitation of the length of the traditional horizontal rod and realizes the precise control of the plane size of the erection area. Compared with the prior art, it can effectively realize the connection of the two vertical poles according to the distance requirements between the vertical poles of the two formwork support frames, and there is no need to cut the horizontal rod on site due to the change in length during connection, which causes waste and increases the construction cost.

[0037] like Figure 1As shown, an auxiliary adjustment handle is provided in the center of the tube body, and the auxiliary adjustment handle is used to assist in adjusting the length of the horizontal rod, providing a convenient operation method for the user to adjust the length of the horizontal rod, making the adjustment process simpler and more intuitive, and improving the operation efficiency. By holding the auxiliary adjustment handle and then driving the tube body to rotate through the auxiliary adjustment handle, the length of the horizontal rod can be easily changed to adapt to the situation of non-standard modules encountered in the erection of the formwork scaffolding. Whether it is necessary to increase or decrease the length of the horizontal rod, it can be achieved by operating the auxiliary adjustment handle without using other tools or performing complicated operations. In addition, the auxiliary adjustment handle may also have a stabilization function, and is connected to the auxiliary adjustment handle through an additional fixing device, so that after adjusting to the appropriate length, the horizontal rod can remain stable and will not change unexpectedly during use. It helps to improve the stability and safety of the equipment.

[0038] Buckle joints, such as Figure 2 As shown, the snap joint is arranged at both ends of the tube body, the snap joint is fixedly connected to the screw rod, and the snap joint is used to connect the formwork support frame. The snap joint includes a mounting portion and a plug-in arranged along the radial direction of the mounting portion. The mounting portion is used to connect the screw rod and the formwork support portion, and the plug-in is used to fix the mounting portion and the formwork support frame together. The plug-in can be made of an iron sheet with a thickness of 3 to 5 mm to ensure the stability of the connection during plugging.

[0039] In some embodiments, one end of the screw rod near the buckle joint is welded to the buckle joint. By welding the screw rod and the buckle joint together, a permanent connection can be created, which is more secure and reliable than traditional bolts, rivets or adhesive connections. After welding, the screw rod and the buckle joint will form a whole, making the overall strength of the horizontal rod higher.

[0040] In some embodiments, the auxiliary adjustment handle is U-shaped. The design of the U-shaped handle allows the user to easily rotate the tube body, and the operation can be easily completed with one hand, and the other hand can also fix the template support frame to be connected, so as to easily complete the installation operation.

[0041] like Figure 2 As shown, a slot is provided in the middle of the mounting portion, and the slot is used to match a template support frame with a connecting plate, so that the slot can be inserted into the connecting plate to stably connect the template support frame horizontally.

[0042] In some embodiments, the plug-in is a pin that gradually narrows along the length direction, and the top width of the pin is greater than the bottom width. The plug-in adopts a pin that gradually narrows along the length direction, which can effectively help strengthen the connection between the mounting portion and the template support frame. An anti-slip portion is provided at the bottom end of the pin. The anti-slip portion is used to prevent the plug-in from falling out. The anti-slip portion of the plug-in can be a protrusion along the bottom surface of the plug-in, and the processing method can be to punch in a small iron column, and the length of the small iron column is greater than the width of the socket to limit the movement of the plug-in. It can also be a round head at the bottom end of the plug-in, and the diameter of the widest part of the round head is slightly larger than the socket, thereby playing a role in limiting the movement of the plug-in.

[0043] It is worth noting that in addition to the above-mentioned implementation modes, the anti-detachment portion may also adopt other forms, as long as the plug-in is not detached and lost, which will not be described in detail here.

[0044] This embodiment also provides a template support frame, including the above-mentioned adjustable horizontal rod, and also including a support frame, and the support frames are connected by the horizontal rod. The support frame includes a plurality of vertical rods, each of which is fixedly connected to a mounting plate, the mounting portion clamps the mounting plate, the plug-in is inserted into the mounting plate, and the mounting plate is used to connect with the mounting portion. The inner wall of the mounting portion elastically abuts against the outer wall of the vertical rod, and the elasticity between metals is used to make it firmly installed.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
