Description

Technical Field

[0001] The invention belongs to the technical field of beam installation construction, and in particular relates to a temporary fixing construction device for beam installation and a beam construction method. Background Art

[0002] In the related technology, during the construction of steel structures, the steel beams need to be temporarily fixed with the assistance of lifting equipment during the installation process until the node construction is completed. Not only does this waste the man-hours of the lifting equipment, but also due to the flexibility of the slings and the difficulty of operating the lifting equipment, it is difficult to ensure the stability and accuracy during the installation process. There are great safety risks in the construction process, and the installation efficiency is low. Summary of the invention

[0005] When a steel beam is connected to a steel column or a steel beam, the connection surface is not a smooth vertical surface, and the steel beam cannot be built by welding and installing angle steel.

In the related technology, a lifting device is used to suspend the steel beam to be installed, and the lifting device is used to find the position and height, and then the connection node is constructed. After the node construction is completed, the suspension device is no longer under stress, the connection between the suspension device and the steel beam is removed, and the lifting device is removed, resulting in the lifting device being occupied for a long time, and it is difficult to ensure the stability and accuracy during the installation process.

[0046] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0047] like Figure 1-Figure 4 As shown, the temporary fixing construction device for beam installation of an embodiment of the present invention includes a frame 1 and a connecting component 2, the frame 1 has a first positioning portion 14 and a first supporting portion, the first positioning portion 14 is in the shape of a U-shaped groove; the connecting component 2 is arranged at the notch of the first positioning portion 14, the connecting component 2 and the frame 1 are detachably connected, the beam 3 is arranged at the first positioning portion 14, and is fixed between the connecting component 2 and the frame 1; the first supporting portion is used to abut against the structure at the beam installation station 4, so that the beam 3 is supported at the beam installation station 4 through the first supporting portion.

[0048] It should be understood that the connecting component 2 and the frame 1 are two components, which can be detachably connected together to facilitate assembly and installation on the beam 3. The first positioning portion 14 is in the shape of a U-shaped groove. During installation, the frame 1 is first placed across the beam 3 so that the beam 3 is located in the first positioning portion 14 for preliminary positioning. Then, the frame 1 and the beam 3 are connected as a whole through the connecting component 2 to stabilize the relative positions of the frame 1 and the beam 3. The first supporting portion is used to abut against the structure at the beam installation station 4. After the temporary fixing construction device for beam installation is assembled on the beam 3, the beam 3 is hoisted to the beam installation station 4 by a lifting device. Then, the beam 3 can be supported on the structure by the first supporting portion. At this time, there is no need to continuously lift the beam 3 with the help of the lifting device, and the working hours of the lifting device are no longer required, which greatly improves the turnover and application efficiency of the equipment of the construction length, and can more reasonably plan the project construction process and improve the construction progress.

[0049] After the first supporting portion of the embodiment of the present invention abuts against the structure, the position of the beam body 3 can be ensured to be relatively stable without shaking, which makes it easier to assemble the connection nodes and improves the assembly accuracy.

[0050] Therefore, the temporary fixing construction device for beam installation in the embodiment of the present invention can arrange the frame 1 and the connecting component 2 on the beam 3, and use the first supporting part of the frame 1 to support the beam 3 on the structure at the beam installation station 4, thereby reducing the operating hours of the lifting equipment and improving the efficiency and safety of the construction work.

[0051] In some embodiments, the frame 1 includes a crossbeam 11 and two longitudinal beams 12. The two longitudinal beams 12 are respectively arranged at both ends of the length direction of the crossbeam 11. The length direction of the longitudinal beam 12 is orthogonal to the length direction of the crossbeam 11. A first positioning portion 14 is formed between the crossbeam 11 and the two longitudinal beams 12.

[0052] The frame 1 further includes a support beam 13 , which is connected to the cross beam 11 and extends in a direction orthogonal to both the length direction of the cross beam 11 and the length direction of the longitudinal beam 12 to form a first support portion.

[0053] The cross beam 11 and the two longitudinal beams 12 form a U-shaped frame 1, the first positioning portion 14 is in the shape of a U-shaped groove, the beam body 3 is a horizontal beam, the cross beam 11 is arranged along the width direction of the beam body 3 and is located at the top of the beam body 3, the longitudinal beams 12 are arranged along the height direction of the beam body 3 and are located on both sides of the width direction of the beam body 3, and the connecting component 2 is located at the bottom of the beam body 3, which is used to connect the two longitudinal beams 12, so that the beam body 3 can be fixed in the first positioning portion 14 of the frame 1.

[0054] The support beam 13 is used to overlap with the structure, so the support beam 13 needs to extend outward for a certain distance. The extension direction of the support beam 13 in the embodiment of the present invention is the same as the length direction of the beam body 3. The support beam 13 extends in a direction orthogonal to the length direction of the cross beam 11 and the length direction of the longitudinal beam 12 (a direction parallel to the horizontal plane), so as to ensure that after the beam body 3 is hoisted into place, the support beam 13 can be overlapped with the structure, thereby supporting the entire beam body 3.

[0055] In some embodiments, the cross beam 11 and the support beam 13 are both H-shaped steels, and the longitudinal beam 12 is H-shaped steel or channel steel.

[0056] In order to ensure the structural stability of the frame 1, the cross beam 11 and the support beam 13 are both made of H-shaped steel, and the longitudinal beam 12 can be made of H-shaped steel or channel steel.

[0057] The cross beam 11 and the support beam 13 bear a large bending force, so the H-shaped steel can ensure sufficient rigidity to prevent its deformation, while the longitudinal beam 12 mainly bears the tensile force along its length direction, so channel steel can be used, and of course H-shaped steel can also be used.

[0058] Furthermore, the spacing distance between the two longitudinal beams 12 is greater than the width of the beam body 3 .

[0059] In the embodiment of the present invention, when fixing the beam body 3, the cross beam 11 and the connecting component 2 are used to support and limit the top and bottom of the beam body 3, that is, the relative position stability of the beam body 3 can be guaranteed. By constraining the spacing distance between the two longitudinal beams 12, the beam body 3 can be moved laterally between the two longitudinal beams 12, which is convenient for the installation between the frame 1 and the beam body 3. At the same time, according to the assembly requirements of the connection nodes of the beam body 3, the relative position between the frame 1 and the beam body 3 can be adjusted while ensuring the stability of the beam body 3, which has higher flexibility.

[0060] In some embodiments, the connecting component 2 includes a top plate 21 and two side plates 22 . The two side plates 22 are respectively arranged at two ends of the length direction of the top plate 21 , and the two ends of the length direction of the side plates 22 are orthogonal to the length direction of the top plate 21 .

[0061] The top plate 21 has a first abutting surface 23, and the side plate 22 has a second abutting surface 24. The first abutting surface 23 is arranged opposite to the bottom wall of the first positioning portion 14. The first abutting surface 23 and the bottom wall of the first positioning portion 14 are used to abut against the opposite side walls of the beam body 3 respectively. The second abutting surfaces 24 of the two side plates 22 abut against the side walls of the first positioning portion 14.

[0062] In the embodiment of the present invention, the connecting component 2 is located in the U-shaped groove of the first positioning portion 14, the two side panels 22 can be positioned in abutment with the side walls of the U-shaped groove, the top plate 21 can be arranged relative to the cross beam 11 to fix the beam body 3, and the side panels 22 also have the function of reinforcing the structure of the top plate 21. At the same time, there is sufficient operating space between the two side panels 22, which facilitates the connection between the connecting component 2 and the frame 1 and makes the operation more convenient.

[0063] Furthermore, the top plate 21 and the side plates 22 are both channel steels. While meeting the structural strength requirements, the embodiment of the present invention uses channel steels to facilitate assembly and disassembly of the connector 26 between the side plates 22 and the frame 1, thereby facilitating operation.

[0064] Furthermore, a first groove is defined between the two side plates 22 , and the first groove is located on a side of the top plate 21 away from the first abutting surface 23 .

[0065] That is to say, the U-shaped arrangement of the top plate 21 and the two side plates 22 can improve the structural stability. The two side plates 22 can increase the contact area with the frame 1, and improve the structural stability between the connecting component 2 and the frame 1. The first groove reserves an operating space for the disassembly between the connecting component 2 and the frame 1, which facilitates the disassembly and assembly of the connecting part 26 in the first groove.

[0066] When the structure abutting against the first support part is not aligned with the beam body 3 in the vertical direction, the position of the first support part may not be limited. However, when the structure abutting against the first support part is flush with the beam body 3 in the vertical direction, the first support part is limited to ensure that the connection node of the beam body 3 is accurately aligned after the first support part abuts against the structure, thereby improving the working efficiency.

[0067] Therefore, in the embodiment of the present invention, the lower end surface of the first supporting portion is the third abutting surface 131 , which is used to abut against the structure at the beam installation station 4 , and the third abutting surface 131 is flush with the bottom wall of the first positioning portion 14 .

[0068] The third abutting surface 131 not only plays a role of abutting against the structure for support, but also limits the position of the beam body 3 in the vertical direction, thereby improving the efficiency and accuracy of the installation of the beam body 3 .

[0069] Of course, when the third abutting surface 131 is not flush with the bottom wall of the first positioning portion 14 , the height can be adjusted by providing a pad, a jack or other equipment.

[0070] In some embodiments, the frame 1 and the connecting components 2 are each in two groups, and the frame 1 and the connecting components 2 are disposed at both ends of the beam 3 .

[0071] Both ends of the beam body 3 are provided with temporary fixing construction devices for beam body installation, so the beam body 3 can be supported on the structure at the beam body installation station 4 by two sets of temporary fixing construction devices for beam body installation.

[0072] In some embodiments, the temporary fixing construction device for installing the beam body also includes a connecting piece 26, one of the side panel 22 and the frame body 1 is provided with a long connecting hole 25, and the other is provided with a circular or long connecting hole 25, and the side panel 22 and the frame body 1 are detachably and fixedly connected by the connecting piece 26 arranged in the connecting hole 25.

[0073] By arranging the long strip-shaped connecting holes, the distance between the frame body 1 and the connecting component 2 can be adjusted according to the height of the beam body 3, thereby improving the scope of use. The connecting member 26 can be a connecting bolt and a connecting nut.

[0074] In the frame body 1 of the embodiment of the present invention, the cross beam 11 and the longitudinal beam 12 and the cross beam 11 and the supporting beam 13 are fixed by welding, and the top plate 21 and the side plate 22 in the connecting component 2 are also fixed by welding.

[0075] The beam body 3 in the embodiment of the present invention may be a steel beam or a non-steel structure beam body 3 .

[0076] The structure at the beam installation station 4 can be a structure such as a column or other stiffening rib plate on the beam 3 that has been installed and a connecting stand.

[0084] S105. After the beam body is installed, remove the beam body and install a temporary fixing construction device.

[0085] After the construction of the connecting nodes of the beam body is completed, the beam body can be supported on the known structure through the connecting nodes. At this time, the temporary fixed construction device installed on the beam body can be removed. When the weight of the temporary fixed construction device installed on the beam body is heavy, it can be disassembled with the help of lifting equipment or a small electric hoist.

[0086] The beam construction method according to the embodiment of the present invention is used for disassembling the beam, and specifically comprises the following steps:
