Description

Technical Field

[0001] This utility model relates to the technical field of steel structure auxiliary tools, specifically a pre-assembled steel component connector. Background Technology

[0002] Steel components refer to steel structural composite components that can bear and transmit loads, made of steel plates, angle steel, channel steel, I-beams, welded or hot-rolled H-beams cold-bent or welded and connected by connectors. Steel component systems have comprehensive advantages such as light weight, factory manufacturing, quick installation, short construction period, good seismic performance, fast investment recovery and less environmental pollution. Compared with reinforced concrete structures, they have unique advantages in the three aspects of "high, large and light".

[0003] Steel components typically require two or more components to be butt-jointed and welded together. Before welding, the steel components need to be pre-assembled according to the welding shape. Pre-assembly is to improve the efficiency of subsequent steel structure welding.

[0004] However, the positioning of steel components during pre-assembly and welding is cumbersome and time-consuming, which does not meet the current requirements. Therefore, we propose a pre-assembly connector for steel components. Utility Model Content

[0005] The purpose of this utility model is to provide a pre-assembled steel component connector to solve the problems mentioned in the background art, such as the cumbersome and time-consuming positioning operation of steel components during pre-assembly and welding.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pre-assembled steel component connector, comprising two bases, with a support frame fixed to the upper surface of the two bases at their adjacent ends, a crossbeam detachably mounted on the top of the support frame, and a positioning strip fixed to the same side of the support frame and the crossbeam, the positioning strip comprising a fixing part, one end of the fixing part being fixed to the support frame and the crossbeam, the other end of the fixing part being fixed to an elastic bending part, the other end of the elastic bending part being fixed to a guide part, and an internal fitting piece provided on the inner side of the elastic bending part.

[0007] Preferably, the fixing part and the guiding part are both made of hard steel plates, and the elastic bending part is made of spring steel.

[0008] Preferably, the inner bonding piece is V-shaped, and one side of the inner bonding piece is on the same straight line as the guide portion, and the other end of the inner bonding piece is welded and fixed to the inner wall of the elastic bending portion.

[0009] Preferably, the inner sides of both ends of the support frame are provided with positioning slots, and the ends of both ends of the crossbeam are provided with positioning protrusions, which are slidably engaged with the inner sides of the positioning slots.

[0010] Preferably, a plurality of linearly arranged lifting platforms are slidably mounted on the upper surface of the base, and the lifting platforms are hollow inside and have an open bottom.

[0011] Preferably, an electric telescopic rod is installed inside the lifting platform, with the bottom end of the electric telescopic rod fixed to the base and the top end of the electric telescopic rod fixed to the lifting platform.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. When steel components are joined together, this utility model guides the two steel components towards the middle of the support frame through four guide parts, and then uses four elastic bending to adjust the spacing between the four positioning strips, so that the internal bonding piece elastically deforms and fits the outer surface of the steel component, so that the axes of the two steel components coincide, simplifying the operation process of positioning the two steel components, saving operation time and improving positioning efficiency.

[0014] 2. This invention uses multiple lifting platforms to support the steel components, ensuring that the two steel components are connected at the same height, thus avoiding misalignment or deviation caused by inconsistent heights between the two steel components. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figures 1 to 4 As shown, a pre-assembled steel component connector has a support frame 2 fixed to the upper surface of the two bases 1 that are close to each other. A crossbeam 3 is detachably installed on the top of the support frame 2. Positioning strips 4 are fixed on the same side of the support frame 2 and the crossbeam 3. The positioning strip 4 includes a fixing part 41. One end of the fixing part 41 is fixed to the support frame 2 and the crossbeam 3. The other end of the fixing part 41 is fixed to an elastic bending part 42. The other end of the elastic bending part 42 is fixed to a guide part 43. An internal fitting piece 6 is provided on the inner side of the elastic bending part 42. The steel component is positioned and guided towards the middle of the support frame 2 by four symmetrically distributed positioning strips 4, so as to ensure that the center of the steel component coincides with the center of the support frame 2 and avoid positional deviation of the two steel components during positioning.

[0022] Both the fixing part 41 and the guide part 43 are made of hard steel plates, and the elastic bending part 42 is made of spring steel. The elastic bending part 42 is elastic and can bend outward after being subjected to force, thereby increasing the distance between the four adjacent guide parts 43 and ensuring that the steel component can smoothly enter between the four fixing parts 41.

[0023] The inner bonding piece 6 is V-shaped and one side of the inner bonding piece 6 is on the same straight line as the guide part 43. The other end of the inner bonding piece 6 is welded and fixed to the inner wall of the elastic bending part 42. The unfixed end of the V-shaped inner bonding piece 6 can bend towards the elastic bending part 42 after being subjected to force, ensuring that the inner bonding piece 6 always adheres to the outer surface of the positioned steel component.

[0024] The inner sides of both ends of the support frame 2 are provided with positioning slots 7, and the ends of both ends of the crossbeam 3 are provided with positioning protrusions. The positioning protrusions are slidably engaged with the inner side of the positioning slots 7. The crossbeam 3 can be removed from the support frame 2 simply by sliding it. This makes it easy to remove the welded steel components after the two steel components have been welded together.

[0025] Multiple linearly arranged lifting platforms 5 are slidably installed on the upper surface of the base 1. The lifting platform 5 is hollow inside and has an open bottom. An electric telescopic rod is installed inside the lifting platform 5. The bottom end of the electric telescopic rod is fixed to the base 1, and the top end of the electric telescopic rod is fixed to the lifting platform 5. The height of the lifting platform 5 is adjusted by the electric telescopic rod, thereby supporting steel components of different thicknesses and making the center of the steel component coincide with the center of the support frame 2.

[0026] Working principle: First, adjust the top height of the lifting platform 5 according to the thickness of the steel component to be welded. Then, activate the electric telescopic rod inside the lifting platform 5, causing the top of the electric telescopic rod to extend and move the lifting platform 5. The distance between the top surface of the lifting platform 5 and the center line of the support frame 2 is half the thickness of the steel component. At this point, place the steel component on the upper surface of the lifting platform 5 and push the two steel components to slide on the surface of the lifting platform 5 and move towards the support frame 2. When the steel components approach the support frame 2 and the crossbeam 3, they press against the crossbeam 3. During the movement, the steel components contact the guide part 43 and squeeze the guide part 43. At this time, the guide part 43 applies a square force to the steel component. The force causes the steel component to shift on the surface of the lifting platform 5. At the same time, the elastic bending part 42 bends and increases the distance between adjacent guide parts 43. After the steel component shifts on the surface of the lifting platform 5, it contacts all four guide parts 43. At this time, the center of the steel component coincides with the center of the support frame 2. Meanwhile, the four internal bonding pieces 6 are squeezed and bonded to the outer surface of the steel component. The operator only needs to push the two steel components until their ends coincide. Finally, the two steel components are welded. After welding, the crossbeam 3 is removed from the support frame 2, and the welded steel component can be taken out. This simplifies the operation process of positioning the two steel components, saves operation time, and improves positioning efficiency.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
