Description

Technical Field

[0001] The utility model belongs to the field of construction equipment, and in particular relates to an installation device for supporting between upper and lower steel beams. Background Art

[0002] During the construction of steel structures, in order to ensure the stability and safety of the main structure, it is often necessary to install temporary supports after the main structure is installed. These supports serve as support for the subsequent installation of special structures on the upper floor, and are responsible for effectively transferring the load to the structure below. At present, the efficiency of temporary support docking installation for steel structures is not high. The supporting steel components need to be lifted by a large crane and hung in the air for a long time. Workers calibrate the support installation position before welding. During the welding process, the supporting steel components are prone to movement, resulting in an offset in the installation position. The support construction is difficult, and the actual on-site operation is relatively inconvenient, which affects the overall construction progress of the project. It is also time-consuming and has a high risk factor. Therefore, there is an urgent need to develop an installation device for supporting between upper and lower steel beams. Utility Model Content

[0030] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of the specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. The technical features of the various embodiments of the present invention may be combined accordingly, provided that there is no conflict between them.

[0031] like Figure 1 As shown, as a preferred embodiment of the present invention, this embodiment provides an installation device for supports between upper and lower steel beams, comprising a fixed base 1, a sliding module 2, and two jacks 3. The fixed base 1 is fixedly mounted on the lower steel beam 5, the sliding module 2 is disposed above the fixed base 1, and jacks 3 are disposed between the fixed base 1 and the sliding module 2 for lifting supports 4, wherein the supports 4 are disposed between the upper and lower steel beams 5. In this embodiment, the supports 4 are made of square steel tubes, and the steel beams 5 are made of H-shaped steel. In other embodiments, the supports 4 and steel beams 5 may be made of other suitable shapes and materials according to actual construction requirements.

[0032] like Figure 2 As shown, the fixed base 1 consists of four sliding rails 1-1, two fixing mechanisms 1-2, and two adjustment mechanisms 1-3. The two fixing mechanisms 1-2 are spaced parallel to each other on either side of the lower steel beam 5. Each fixing mechanism 1-2 has a connection hole at each end. Two adjustment mechanisms 1-3 are perpendicularly positioned on either side of the fixing mechanisms 1-2. Each adjustment mechanism 1-3 has several connection holes spaced along its length. Both adjustment mechanisms 1-3 are detachably connected to the sliding rails 1-1 via fixings. An angle steel with connection holes is fixed to the bottom of each fixing mechanism 1-2. Nuts are welded to each connection hole. During construction, bolts or pins are screwed into the nuts to abut against the lower end of the lower steel beam 5, thereby securing the fixing mechanism 1-2 to the steel beam 5. In this embodiment, the angle steel at the bottom of each fixing mechanism 1-2 has two connection holes. During construction, bolts are screwed into the nuts until they abut against the flange at the lower end of the steel beam 5, securing the fixing mechanism 1-2 solely to the steel beam 5. This ensures that the entire fixed base 1 is securely mounted on the steel beam 5. In other embodiments, the number of angle steel connection holes at the bottom of the fixing mechanism 1-2 can be increased or decreased according to the size of the support 4. If the support 4 is larger, more connection holes can be opened to increase the installation stability of the fixing mechanism 1-2. Otherwise, the number of connection holes can be appropriately reduced to reduce the production difficulty.

[0033] Each sliding track 1-1 comprises a round rod base and a round rod vertically fixed to the base. The base is positioned inside the intersection of the fixing mechanism 1-2 and the adjustment mechanism 1-3. The two sidewalls of the base are provided with connection holes for connecting to the fixing mechanism 1-2 and the adjustment mechanism 1-3, respectively. Fixing members pass through the connection holes in the sidewalls of the base and the connection holes at different locations on the adjustment mechanism 1-3 to accommodate steel beams 5 of varying widths on site. A jack stop collar 1-4 is fixed to the outside of each adjustment mechanism 1-3, which is used to secure the jack 3. The jack stop collar 1-4 is a double semicircular clamp made of thin steel plate, with a circular center and parallel straight steel plates at both ends. One end of the parallel straight steel plate is welded to the adjustment mechanism 1-3, and the other end has bolt holes. The diameter of the center circle of the jack stop collar 1-4 is adjusted according to the bottom diameter of the jack 3. The jack 3 is then secured and restrained by tightening the bolts.

[0034] like Figure 3 As shown, the sliding module 2 includes four limiting mechanisms 2-1, two lifting arms 2-2 and two supporting and fixing mechanisms 2-3. The two supporting and fixing mechanisms 2-3 are arranged in parallel and spaced apart on both sides of the support 4, and each supporting and fixing mechanism 2-3 has connecting holes at both ends. The two lifting arms 2-2 are arranged vertically on both sides of the supporting and fixing mechanisms 2-3. Each lifting arm 2-2 has a number of connecting holes spaced apart along the length direction. The two and the limiting mechanisms 2-1 are detachably connected through fixing parts. Each supporting and fixing mechanism 2-3 is provided with a fixing hole for fixing the support 4, and a nut is welded on the fixing hole. During construction, a bolt or a pin is screwed in to tighten against the support 4, thereby achieving the purpose of fixing the support 4. Each limiting mechanism 2-1 includes two mutually perpendicular connecting plates and a round tube fixed at the connection between the two connecting plates. In other embodiments, the two mutually perpendicular connecting plates can be replaced with L-shaped steel or angle steel, and connecting holes are provided on both connecting plates of the limiting mechanism 2-1. The fixing parts pass through the connecting holes on the connecting plates and the different connecting holes on the cantilever 2-2 to adapt to the steel beams 5 of different widths on site.

[0035] To achieve component recycling and reduce production costs, removable components such as bolts or pins can be used as fixings. The diameter of the circular tube of the limiting mechanism 2-1 is larger than the diameter of the round rod of the sliding track 1-1. The circular tube is installed outside the round rod of the sliding track 1-1. The round rod of the sliding track 1-1 has a limiting effect on the sliding module 2, and the entire sliding module 2 moves up and down along the direction of the circular rod.

[0036] The outer sides of the two cantilever arms 2-2 are welded and fixed with height limit plates for limiting the height of the jacks 3. The height limit plates are cantilevered outwards and are located above the jacks 3. During construction, the lower edges of the two height limit plates abut against the tops of the jacks 3. The two height limit plates limit the lifting height of the two jacks 3, achieving synchronous lifting of both sides of the support 4, thereby ensuring better contact between the support 4 and the steel beam 5.

[0037] like Figure 4 As shown, after the support 4 is fixed on the device, the support 4 is lifted by adjusting the height of the jack 3. Due to the limitation of the height limit plate, the height of the top of the two jacks 3 is the same, so that the lifting height on both sides of the support 4 is the same, so that the top of the support 4 is tightly pressed against the upper steel beam 5. In order to facilitate the installation of the support 4, the length of the support 4 is generally smaller than the distance between the two adjacent steel beams 5 above and below. Therefore, there is a gap between the bottom end of the support 4 and the lower steel beam 5. A filling steel plate 6 is filled in the gap. The thickness of the filling steel plate 6 can be changed according to the distance between the bottom end of the support 4 and the steel beam 5, so that the filling steel plate 6, the support 4 and the upper and lower steel beams 5 are tightly pressed against each other. In order to increase stability and improve the safety of workers during construction, the filling steel plate 6 and the support 4, the support 4 and the upper steel beam 5, and the filling steel plate 6 and the lower steel beam 5 are fixedly connected by welding.

[0038] Next, this embodiment also provides a construction process for installing the support between the upper and lower beams using the above device, which is specifically as follows:

[0039] Step 1: If Figure 5 As shown, the installation position between the fixing mechanism 1-2 and the adjusting mechanism 1-3 is determined according to the width of the lower steel beam 5, and the four sliding rails 1-1 of the fixing base 1, the two fixing mechanisms 1-2, and the two adjusting mechanisms 1-3 with jack limit hoops 1-4 welded on both sides are installed on the lower steel beam 5. The fixing base 1 is fixed to the lower steel beam 5 by tightening the bolts that match the connection holes on the angle steel at the bottom of the fixing mechanism 1-2;

[0040] Step 2: If Figure 6 As shown, the round tubes of the four limiting mechanisms 2-1 of the sliding module 2 are sleeved on the outside of the round rod of the sliding track 1-1, thereby limiting the moving direction of the sliding module 2 and ensuring that the components of the sliding module 2 and the fixed base 1 are parallel to each other.

[0041] Step 3: If Figure 7 As shown, the support 4 is lifted by a crane or other equipment and prevented from being placed in the sliding module 2, the sliding module 2 is lifted to a suitable position, and the bolts that match the fixing holes on the support fixing mechanism 2-3 are tightened to fix the support 4 in the sliding module 2 to prevent the support 4 from shaking or shifting during the lifting process of the jack 3;

[0042] Step 4: If Figure 8 As shown, the jack 3 is installed in the circle in the middle position of the jack limit hoop 1-4, and the bolts at the end are tightened to fix the jack 3. By adjusting the height of the jack 3, the jack 3 is lifted upward, driving the sliding module 2 to lift, thereby driving the support 4 to lift steadily until the upper end of the support 4 is tightly against the upper steel beam 5;

[0043] Step 5: If Figure 9 As shown, there is a gap between the lower end of support 4 and the lower steel beam 5. Therefore, a filler steel plate 6 of appropriate thickness is inserted. The filler steel plate 6 cooperates with the support 4 to support the upper and lower steel beams 5. The filler steel plate 6 is fixed to the support 4, between the support 4 and the upper steel beam 5, and between the filler steel plate 6 and the lower steel beam 5 by welding to increase the stability of the overall structure. After welding is completed, the fixed base 1, sliding module 2, and jack 3 are disassembled and stored for use in the next construction.

[0044] The above-described embodiment is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Persons skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, any technical solution obtained by equivalent substitution or equivalent transformation falls within the scope of protection of the present invention.
