Description

Technical Field

[0002] During the construction process, workers need to work at heights. In order to prevent people from falling and objects from falling, a safe and reliable working platform must be built. By fully paving the I-beam secondary beams and welding them for reinforcement, a stable structural foundation can be provided to reduce the risk of collapse and deformation. The steel mesh is set up to form a closed structure, which can effectively prevent small tools and materials from falling from the gaps and avoid harm to the people and environment below. The formation of a complete construction road helps workers move and operate more conveniently during the construction process, reducing time wasted due to inconvenient passage, thereby improving overall construction efficiency.

[0003] When the platform frame is erected, multiple main beam I-beams and secondary beam I-beams need to be fixedly connected. The existing secondary beams and main beams are generally connected by welding.

In addition, when the secondary beams and the main beams are installed, they need to be manually calibrated repeatedly for verticality. This process is cumbersome and affects the connection efficiency. Therefore, a cantilevered I-beam secondary beam connection structure is proposed. Utility Model Content

[0030] Example 1

[0031] Reference Figure 1 - Figure 6 , which is the first embodiment of the utility model, and provides a cantilever I-beam secondary beam connection structure, including a cantilever I-beam 1 and a secondary beam 2. The bottom surface of the cantilever I-beam 1 is fixedly connected with a side beam 101, and one end of the side beam 101 is provided with a connecting groove 101a, and the connecting groove 101a is welded and connected to the wall embedded part; through the side beam 101 and the connecting groove 101a, it is welded to the wall embedded part, and on the upper layer, the cantilever I-beam 1 is locked and fixed with a U-shaped steel to realize the installation of the cantilever I-beam 1, and then the secondary beam 2 is laid, and the secondary beam 2 is vertically laid flat on the upper surface of the cantilever I-beam 1;

[0032] The correction component 3 includes an adjustment plate 301 installed on the upper surface of the secondary beam 2, an adjustment groove 301a provided on the inner wall of the adjustment plate 301, a bidirectional screw 301b rotatably connected to the inner wall of the adjustment groove 301a, a slide seat 301c symmetrically installed on the side of the bidirectional screw 301b, a turning handle 301d fixed to one end of the bidirectional screw 301b, and a positioning column 302 fixed to the bottom surface of the slide seat 301c. Through the correction component 3, two groups of positioning columns 302 can be displaced at the same time, driving two groups of fixing components to simultaneously fix and press the angle between the cantilever I-beam 1 and the secondary beam 2. By setting the adjustment groove 301a, the bidirectional screw 301b and the slide seat 301c, the distance between the positioning columns 302 can be adjusted arbitrarily, which is convenient for connecting cantilever I-beams 1 and secondary beams 2 of different widths, thereby improving the connection flexibility;

[0033] The fixing assembly includes a connecting member 4, a first fixing member 5 and a second fixing member 6 which are sleeved on the peripheral side of the positioning column 302; a first high-strength bolt 8 is installed between the first fixing member 5, the second fixing member 6 and the connecting member 4; the first fixing member 5 is pressed onto the inner wall of the secondary beam 2, and the second fixing member 6 is pressed onto the inner wall of the cantilevered I-beam 1; and a pressure plate 7 is also included, which is pressed onto the inner wall of the secondary beam 2; by pressing the first fixing member 5 onto the inner bottom surface of the secondary beam 2 and pressing the second fixing member 6 onto the inner top surface of the main beam at the same time, fixation is achieved at the angle between the cantilevered I-beam 1 and one side of the secondary beam 2.

[0034] Specifically, the connecting member 4 is a connecting plate 401, and the upper surface of the connecting plate 401 is provided with a first through hole 401a, a first fixing hole 401b and a mounting hole 401c. The first fixing member 5 is a first fixing plate 501, and the surface of the first fixing plate 501 is provided with a second through hole 501a and a second fixing hole 501b. The second fixing member 6 is a second fixing plate 601, and the surface of the second fixing plate 601 is provided with a third through hole 601a and a third fixing hole 601b. The positioning column 302 passes through the first through hole 401a, the second through hole 501a and the third through hole 601a. ​​The first high-strength bolt 8 passes through the first fixing hole 401b, the second fixing hole 501b and the third fixing hole The first fixing hole 401b, the second fixing hole 501b and the third fixing hole 601b are provided, so that the first high-strength bolt 8 can stably fix the connecting plate 401 to the first fixing plate 501 and the second fixing plate 601, and the connecting plate 401 can be placed on the upper surface of the cantilevered I-beam 1, so that the first fixing plate 501 and the second fixing plate 601 can completely press the main beam and the secondary beam; by providing the first through hole 401a, the second through hole 501a and the third through hole 601a, when the connecting plate 401, the first fixing plate 501 and the second fixing plate 601 are fixed, the positioning column 302 can be pulled out to carry out the installation at the next angle.

[0035] Furthermore, a horizontal limit rod 402 is fixedly connected to the bottom surface of the connecting plate 401, and the horizontal limit rod 402 is located at the outer top wall of the cantilevered I-beam 1, and the thickness of the horizontal limit rod 402 is less than the cantilevered I-beam 1; since the connecting plate 401 is close to the upper surface of the cantilevered I-beam 1, and the bottom surface of the secondary beam 2 is installed close to the upper surface of the cantilevered I-beam 1, the horizontal limit rod 402 is close to the outer top wall of the cantilevered I-beam 1. At this time, the connecting plate 401 and the cantilevered I-beam 1 are in a vertically connected state, and then the bottom edge of the secondary beam is aligned with the long edge of the connecting plate 401, so as to achieve vertical paving between the secondary beam 2 and the main beam, avoid the secondary beam 2 from being laid tilted, and even if the angle of the secondary beam 2 is calibrated later, there is no need to move the position of the secondary beam 2 significantly, thereby improving the connection efficiency.

[0036] Furthermore, a first extrusion portion 502 is provided on the bottom surface of the first fixed plate 501, and a second extrusion portion 602 is provided on the upper surface of the second fixed plate 601; the first extrusion portion 502 and the second extrusion portion 602 are both adapted to the position of the I-beam flange. Since the main beam and the secondary beam 2 are both I-beams, and the I-beam flange is thinner to form a certain inclination angle, the extrusion portion can better fit the I-beam flange to improve the connection stability.

[0037] Furthermore, a mounting hole 401c is opened on the upper surface of the connecting plate 401, and a connecting part 701 is fixedly connected to the side wall of the pressure plate 7. The connecting part 701 passes through an adjustable screw hole 701a. A second high-strength bolt 9 is installed between the adjustable screw hole 701a and the mounting hole 401c, and the pressure plate 7 can be fixed by the second high-strength bolt 9.

[0038] Operation process: through the side beam 101 and the connection groove 101a, the cantilever I-beam 1 is welded to the embedded part of the wall, and at the same time, the cantilever I-beam 1 is locked and fixed with a U-shaped steel at the upper layer of the embedded part to realize the installation of the cantilever I-beam 1, and then the secondary beam 2 is laid, and the secondary beam 2 is vertically laid flat on the upper surface of the cantilever I-beam 1; after the secondary beam 2 is laid on the cantilever I-beam 1, the connecting piece 4, the first fixing piece 5 and the second fixing piece 6 are respectively installed at the four angles between the secondary beam 2 and the cantilever I-beam 1 through the correction component 3;

[0039] First, roughly connect the two groups of first fixing plates 501 and the second fixing plates 601 with the connecting plates 401 through the first high-strength bolts 8, and then place the two groups of connecting plates 401 diagonally on the upper surface of the cantilevered I-beam 1, and place the horizontal limit rod 402 close to the outer top wall of the cantilevered I-beam 1. At this time, the connecting plates 401 and the cantilevered I-beam 1 are in a vertical connection state, and then align the bottom edge of the secondary beam with the long edge of the connecting plate 401, so as to achieve vertical tiling between the secondary beam 2 and the main beam, and rotate the first fixing plate 501 and the second fixing plate 601 so that the second fixing plate 601 is attached to the inner top surface of the main beam, and the first fixing plate 501 is attached to the inner bottom surface of the secondary beam 2;

[0040] At this time, by turning the handle 301d, the positions of the two groups of positioning columns 302 are adjusted to a suitable length, so that the two groups of positioning columns 302 are simultaneously inserted into the two groups of connecting plates 401, the first fixing plate 501 and the second fixing plate 601; at this time, the handle 301d is rotated again to retract the two groups of connecting plates 401, so that the connecting plates 401 can press against the outer top wall of the main beam and the outer bottom wall of the secondary beam 2, and then the position of the horizontal limit rod 402 is observed to determine whether the secondary beam 2 is perpendicular to the main beam;

[0041] Then tighten the first high-strength bolt 8 to connect the main beam and the secondary beam 2 with the first fixing plate 501 and the second fixing plate 601. After the installation is completed, the positioning column 302 can be pulled out through the perforation, which is convenient for correcting the position of the connecting parts and fixing plates at other angles; repeat the above operation to connect the four corners of the main beam and the secondary beam 2 through the first fixing plate 501 and the second fixing plate 601. This method greatly improves the connection strength and ensures the connection stability between the secondary beam 2 and the main beam without welding. At the same time, the installation efficiency is high, and the secondary beam 2 and the main beam can be ensured to be in a relatively vertical state, thereby improving the accuracy of the installation. Subsequently, the secondary beam 2 can be separated from the main beam only by removing the bolts, which greatly improves the convenience of disassembly and does not require cutting operations at high altitudes.

[0042] Example 2

[0043] Reference Figure 1 - Figure 6 , which is the second embodiment of the utility model, and is different from the previous embodiment in that: a hook mesh component 702 is provided on the upper surface of the pressure plate 7, and a mesh sheet 10 is fixedly installed on the hook mesh component 702.

[0044] Specifically, the hooking net component 702 includes a spring groove 702a opened on the upper surface of the pressure plate 7, a return spring 702b connected to the inner wall of the spring groove 702a, a slider 702c connected to one end of the return spring 702b, and a hook ring 702d fixed on the upper surface of the slider 702c.

[0045] The rest of the structure is the same as that of Example 1.

[0046] Operation process: by setting the pressure plate 7 and using the second high-strength bolt 9, the pressure plate 7 can be stably pressed onto the inner wall of the secondary beam 2, further improving the connection stability between the secondary beam 2 and the main beam; by setting the hook ring 702d, the hook ring 702d can quickly hook and fix the steel mesh laid in the secondary beam 2, greatly improving the installation efficiency of the steel mesh, and only the hook ring 702d needs to be hooked on the edge of the steel mesh, and the hook rings 702d on both sides can hook the steel mesh at the same time, so as to realize the rapid laying of the steel mesh; and a reset spring 702b is provided, so that the hook ring 702d has a certain buffer distance, which improves the installation flexibility and saves more effort during installation.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
