Description

A screw type clamp for steel frame formwork

Technical Field

The invention belongs to the technical field of building template quick-disassembly system, and in particular relates to a screw-type clamp for a steel frame template.

Background technique

Building formwork is a temporary supporting structure, manufactured according to design requirements, which allows concrete structures and components to be formed according to specified positions and geometric dimensions, maintain their correct positions, and bear the deadweight of the building formwork and external loads acting on it.

The building formwork structure used in cast-in-place concrete structure construction mainly consists of three parts: panel, support structure and connection accessories. The panel is the load-bearing plate that directly contacts the newly poured concrete; the support structure is a temporary structure that supports the panel, concrete and construction load, ensuring that the building formwork structure is firmly combined without deformation or damage; the connection accessories are accessories that connect the panel and the support structure into a whole.

In traditional aluminum alloy formwork, the connection accessories commonly used between aluminum alloy frames are pin-type clamps. However, pin-type clamps are easy to loosen due to vibration and other reasons during construction, and have poor fastening. Therefore, it is necessary to develop a new structure and more universal frame connection clamp.

Detailed ways

A preferred embodiment of the present invention will be described below in conjunction with the accompanying drawings to clearly and completely describe the technical solution in a preferred embodiment of the present invention.

Please refer to FIG. 1 , the present invention includes a connecting square tube, and a first clamping mechanism and a second clamping mechanism installed at two ends of the connecting square tube.

The connecting square tube comprises a connecting square tube body 1 , one end of which is fixedly provided with a fastening mechanism, and the other end of the connecting square tube body 1 is provided with three groups of connecting holes 2 at equal intervals on the opposite tube wall.

The first clamping mechanism includes a square tube-shaped first connecting end 4, which can be sleeved on the outside of the connecting square tube body 1. A group of first mounting holes 5 matching the connecting hole 2 are opened on the tube wall opposite to the first connecting end 4. A first clamping portion 6 is fixedly arranged at the bottom of the first connecting end 4. The inner side of the first clamping portion 6 is bent inwardly into an arc shape, and the end of the arc protrudes inwardly to form a first flange 7.

The second clamping mechanism includes a square tube-shaped second connecting end 9, which can be sleeved on the outside of the connecting square tube body 1. The length of the second connecting end 9 is greater than the first connecting end 4. A group of second mounting holes 10 matching the connecting hole 2 are opened on the relative tube wall near the outer end of the second connecting end 4. A second clamping portion 11 is fixedly provided at the bottom of the second connecting end 9 at a position corresponding to the second mounting hole 10. The inner side of the second clamping portion 11 is bent inwardly into an arc shape, and the end of the arc protrudes inwardly to form a second flange 13.

In this embodiment, a first clamping block 8 is provided in the middle of the outer side of the first clamping portion 6, and a second clamping block 12 is provided in the middle of the outer side of the second clamping portion 11; the edges of the first clamping block 8 and the second clamping block 12 are serrated structures.

In this embodiment, the fastening mechanism includes a fastening screw 3 fixedly arranged at one end of the square tube body 1 , and a corresponding fastening nut 14 is provided on the fastening screw 3 .

In this embodiment, a reinforcing rib is provided at the connection between the first connecting end 4 and the first clamping portion 6 ; and a reinforcing rib is provided at the connection between the second connecting end 9 and the second clamping portion 11 .

In this embodiment, the fastening screw 3 is welded to the inner wall of one end of the connecting square tube body 1 .

Please refer to Figure 2. The installation method of the present invention is: the first connecting end 4 and the second connecting end 9 are respectively sleeved on the connecting square tube body 1 for pre-fixation; then the clamp is installed on a group of relatively arranged steel frames, and the first flange 7 and the second flange 13 are respectively inserted into the clamping grooves on both sides of the steel frame. The clamp is adjusted so that the first clamping part 6 and the second clamping part 11 clamp and fix the steel frame, and then screwed into the first mounting hole 5, the second mounting hole 10 and the connecting hole 2 for fixing, and then further tightened from the side by the fastening screw 3 and the fastening nut 14 to complete the fixed connection process.

Please refer to Figure 3. There is another method of using the present invention, which can be used for traditional aluminum alloy frames. The difference from the above installation method is that the first connecting end 4 and the second connecting end 9 are reversely sleeved on the connecting square tube body 1, that is, the first clamping block 8 and the second clamping block 12 of the clamp are installed oppositely, and the first clamping portion 6 and the second clamping portion 11 cooperate with the serrated rough surfaces of the edges of the first clamping block 8 and the second clamping block 12 to clamp the aluminum alloy frame, and the fastening method is the same as the above method.

The present invention firstly pre-fixes the connecting square tube to the first clamping mechanism and the second clamping mechanism respectively by means of screws, then adjusts the relative position of the clamp and the frame to clamp the frame, and then further tightens it from the side by means of a fastening screw and a fastening nut to complete the fixed connection process, with good fastening performance and convenient removal. The present invention has two installation methods, which can simultaneously realize the fixed connection of the traditional aluminum alloy frame and the new steel frame, and has high versatility.
