Description

Technical Field

[0001] The utility model relates to the technical field of fixing construction column templates, in particular to a fixing fixture for a lintel and a construction column template. Background Art

[0002] Most of the existing reinforcement fixtures for lintel and structural column formwork are fixed with square wood and tension screws. This fixing method has many steps and is prone to deformation, mold movement, and leakage. It is used in large quantities and has a low turnover rate, resulting in a waste of resources. The wall holes left by the screws in the concrete affect the appearance and need to be repaired during later decoration. Summary of the Invention

[0003] The purpose of the utility model is to solve the problems raised in the background technology and to provide a novel fixing fixture for lintel and structural column templates.

[0004] The technical solution of the utility model to achieve the above purpose is as follows:

[0005] A new type of fixing fixture for lintel and structural column templates, including a transverse square tube, a sub-square tube, an extended nut, a mother square tube, a positioning nut, a reinforcing screw, a screw block, a clamping square tube, and a baffle; the transverse square tube is fixedly connected to the sub-square tube, the inner center position of the sub-square tube is fixedly connected to the extended nut, the sub-square tube is inserted into the mother square tube, the inner part of the mother square tube is fixedly connected to the positioning nut, the reinforcing screw is located at the center position of the mother square tube and is engaged with the extended nut, the reinforcing screw is engaged with the positioning nut, the end of the reinforcing screw is fixedly connected to the screw block, the side surface of the transverse square tube is fixedly connected to a clamping square tube, the side surface of the mother square tube is fixedly connected to another clamping square tube, and the reinforcing screw is fixedly connected to the baffle.

[0006] Preferably, the transverse square tube, the sub-square tube, the mother square tube and the clamping square tube form a "U"-shaped structure.

[0007] Preferably, the specifications of the sub-square tube are 40mm*40mm*4.0mm, and the specifications of the mother square tube are 50mm*50mm*4.0mm.

[0008] Preferably, the transverse square tube, sub-square tube, main square tube and clamping square tube are made of galvanized stainless steel.

[0009] Preferably, the length of the transverse square tube is 80 mm, the length of the sub-square tube after being connected to the transverse square tube is 150 mm, the length of the mother square tube is 200 mm, the specification of the extension screw is φ16 mm×200 mm, the specification of the clamping square tube is 40 mm*40 mm*4.0 mm, and the length of the clamping square tube is 500 mm.

[0010] The utility model provides a novel fixing fixture for lintel and structural column formwork, which has the following beneficial effects:

[0011] Through its structural design, this device is composed of a horizontal square tube and a sub-square tube welded together, an extended nut is set in the center, the sub-square tube is inserted into another mother square tube, and a reinforcing screw is arranged in the middle of the mother square tube to engage with the positioning nut in the mother square tube. The outer end of the reinforcing screw is an extended hexagonal screw block. The transverse square tube and the mother square tube have two longitudinal clamping square tubes welded to the transverse square tube and the mother square tube. During use, only an electric wrench is needed to clamp the clamping square tube on the outside of the lintel and structural column template, and the electric wrench is used to tighten the screw block. The rotation of the screw block drives the reinforcing screw to rotate on the positioning nut. The reinforcing screw is located in the extension nut. When the reinforcing screw rotates, it drives the extension nut to rotate on the reinforcing screw, thereby driving the sub-square tube to move toward the center. The movement of the sub-square tube toward the center drives the transverse square tube toward the center. The movement of the transverse square tube toward the center drives the clamping square tube to move toward the center to clamp the template. After the concrete reaches the required strength, the electric wrench is used to loosen the screw block to remove the clamp and achieve reuse. Compared with the existing technology, the utility model is simple to operate and can be dismantled after use, which simplifies the construction process, increases the number of turnovers, and reduces resource waste. It solves the problem that traditional formwork clamps are prone to deformation, mold movement, and slurry leakage, are used in large quantities but have few turnover times, and the problem that the screw holes through the wall need to be repaired during later decoration is left.

[0020] In this embodiment, the horizontal square tube 1, the sub-square tube 2, the main square tube 4 and the clamping square tube 8 form a "U"-shaped structure. The shape of the "U"-shaped structure can better clamp the lintel and structural column templates.

[0021] In this embodiment, the specifications of the sub-square tube 2 are 40mm*40mm*4.0mm, and the specifications of the main square tube 4 are 50mm*50mm*4.0mm. The sub-square tube 2 and the main square tube 4 of conventional specifications can make it more convenient for construction workers to obtain materials.

[0022] In this embodiment, the transverse square tube 1, the sub-square tube 2, the mother square tube 4 and the clamping square tube 8 are made of galvanized stainless steel. The transverse square tube 1, the sub-square tube 2, the mother square tube 4 and the clamping square tube 8 made of galvanized stainless steel have excellent corrosion resistance and high strength and hardness, which can make the utility model have a longer service life.

[0023] In this embodiment, the length of the horizontal square tube 1 is 80 mm, the length of the sub-square tube 2 after being connected to the horizontal square tube 1 is 150 mm, the length of the mother square tube 4 is 200 mm, the specification of the extension screw is φ16 mm×200 mm, the specification of the clamping square tube 8 is 40 mm*40 mm*4.0 mm, and the length of the clamping square tube 8 is 500 mm. This specification can be applied to conventional walls with a thickness of 200 mm-350 mm or conventional lintels with a width of 200 mm-350 mm.

[0024] In this embodiment: the overall shape of the utility model is a "U"-shaped structure, with a horizontal square tube 1 with a specification of 40mm×40mm×4.0mm and a sub-square tube 2 with a length of 80mm and a specification of 40mm×40mm×4.0mm welded together, with a total length of 150mm. An extension nut 3 is provided in the center of the sub-square tube 2, and the sub-square tube 2 is inserted into another 50mm×50mm×4.0mm mother square tube 4 with a length of 200mm. There is a φ16mm×200mm reinforcing screw 6 in the middle of the mother square tube 4, which engages with the positioning nut 5 in the mother square tube 4 and the extension nut 3 in the sub-square tube 2. The outer end of the reinforcing screw 6 is an extended hexagonal screw block 7. There are two longitudinal clamping square tubes 8 with specifications of 40mm×40mm×4.0mm and a length of 500mm on the end sides of the transverse square tube 1 and the mother square tube 4. They are welded to the transverse square tube 1 and the mother square tube 4. This specification is suitable for conventional walls with a thickness of 200mm-350mm or conventional lintels with a width of 200mm-350mm. During use, only an electric wrench is needed to clamp the clamping square tube 8 on the outside of the lintel and structural column formwork, and tighten the screw block 7 with the electric wrench. The rotation of the screw block 7 drives the reinforcing screw 6 to rotate on the positioning nut 5. The reinforcing screw 6 is located in the lengthening nut 3. When the reinforcing screw 6 rotates, it drives the lengthening nut 3 to rotate on the reinforcing screw 6, thereby driving the sub-square tube 2 to move toward the center. The movement of the sub-square tube 2 toward the center drives the horizontal square tube 1 to move toward the center. The movement of the horizontal square tube 1 toward the center drives the clamping square tube 8 to move toward the center to clamp the formwork. After the concrete reaches the strength, only the electric wrench needs to be used to loosen the screw block 7 to remove the clamp for reuse.
