Description

Technical Field

[0001] The utility model belongs to the field of construction equipment, and in particular relates to a multi-span assembled operating platform hung under a steel beam. Background Art

[0002] At present, during the construction of multi-story steel structures, steel beam installation is mostly carried out in a construction environment without floor support plates. Horizontal passages and construction platforms need to be set up to ensure the safety, convenience and efficiency of steel beam installation. Existing multi-story steel structure construction platforms are mostly welding operation platforms in the form of hanging baskets. The operating space of such operation platforms is small. After the welding of a single steel beam is completed, the hanging basket needs to be moved to the bottom of another steel beam, which makes it inconvenient for personnel to move. Existing horizontal passages in multi-story steel structures are mostly for workers to walk directly on the upper part of the steel beams, or to set up platforms on the top of two steel beams as horizontal passages for walking. The former has low safety, and the latter increases construction costs. In the existing technology, the horizontal passage and the construction platform are set up separately, which increases costs and reduces construction convenience.

[0003] Therefore, there is an urgent need to provide a multi-span assembled operating platform hanging under a steel beam that integrates a horizontal channel and a construction platform. Utility Model Content

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.

[0029] In the description of this utility model, it should be understood that the terms "first" and "second" are used only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one of such features.

[0030] like Figure 1 and Figure 2 As shown in FIG. 1 , as a preferred embodiment of the present invention, this embodiment provides a multi-span assembled operating platform suspended from a steel beam, comprising a platform section 1 under the beam, a platform section 2 between spans, and a lifting device 5. The platform section 1 under the beam is disposed below the steel beam 7. Specifically, a lifting belt 4 is provided on the steel beam 7. One end of the lifting device 5 is connected to the lifting belt 4, and the other end is connected to the platform section 1 under the steel beam 7 via a lifting sling 6. The platform section 2 between spans is disposed between adjacent platform sections 1 under the beam.

[0031] The utility model provides a platform section 1 under the beam, comprising a longitudinal beam 1-1 under the beam, a transverse beam 1-2 under the beam, a vertical pole 1-3 under the beam and a vertical pole drag seat 1-6 under the beam, wherein the longitudinal beam 1-1 under the beam, the transverse beam 1-2 under the beam and the vertical pole 1-3 under the beam are all made of square steel pipes.

[0032] like Figure 3 As shown, the lower longitudinal beams 1-1 are arranged in parallel and spaced apart, and a number of lower cross beams 1-2 are fixed between adjacent lower longitudinal beams 1-1 by welding to form the platform frame of the lower platform section. Each lower cross beam 1-2 is fixed vertically between the lower longitudinal beams 1-1 on both sides. A number of lower vertical rod brackets 1-6 are fixed to the lower longitudinal beam 1-1 at intervals along the length direction, and the lower vertical rod brackets 1-6 are fixed to the lower longitudinal beam 1-1 by welding. The lower vertical rod brackets 1-6 are provided with holes for forming a detachable connection with the lower vertical rods 1-3. The bottom of the lower vertical rod 1-3 is vertically inserted into the lower vertical rod bracket 1-6, and bolts are passed through the holes provided in the bottom of the lower vertical rod bracket 1-6 and the bottom of the lower vertical rod 1-3 to fix the two. A cross bar is provided between adjacent lower vertical rods 1-3 to form a platform guardrail.

[0033] In this embodiment, adjacent lower beam uprights 1-3 are secured by welding to first lower beam crossbars 1-4 and second lower beam crossbars 1-5, forming a platform guardrail. These first lower beam crossbars 1-4 and second lower beam crossbars 1-5 can be constructed of square steel tubes, channel steel, angle steel, I-beams, round steel, or other similar steel. It should be noted that in actual construction, one or more crossbars can be installed between adjacent lower beam uprights 1-3, as long as they meet the protective function of the railing.

[0034] In the present invention, a lug plate 1-7 for setting a lifting sling 6 is fixed to the outer side of the lower longitudinal beam 1-1. One end of the lifting sling 6 is connected to the lug plate 1-7, and the other end is connected to the lifting device 5. In this embodiment, the lifting sling 6 adopts a double-chain sling, which is a device used to connect and fix two objects, usually consisting of two chains or slings. The design of the double-chain sling enables it to withstand greater tension and weight. Therefore, in this embodiment, two lug plates 1-7 are fixed to the outer side of each lower longitudinal beam 1-1 by welding, and each lug plate 1-7 is set at a point where the length of the lower longitudinal beam 1-1 is divided into three equal parts to ensure the stability and safety of the connection.

[0035] The inter-span platform section 2 provided by the utility model comprises an inter-span longitudinal beam 2-1, an inter-span transverse beam 2-2, an inter-span vertical pole 2-3 and an inter-span vertical pole drag seat 2-6, wherein the inter-span longitudinal beam 2-1, the inter-span transverse beam 2-2 and the inter-span vertical pole 2-3 are all made of square steel pipes.

[0036] like Figure 3 As shown, the span longitudinal beams 2-1 are arranged in parallel and spaced apart, and a number of span cross beams 2-2 are fixed between adjacent span longitudinal beams 2-1 by welding to form the span platform section platform frame. Each span cross beam 2-2 is fixed vertically between the span longitudinal beams 2-1 on both sides. A number of span vertical pole brackets 2-6 are fixed on the span longitudinal beams 2-1 at intervals along the length direction, and each span vertical pole bracket 2-6 is fixed to the span longitudinal beam 2-1 by welding. The span vertical pole bracket 2-6 is provided with holes for forming a detachable connection with the span vertical pole 2-3. The bottom of the span vertical pole 2-3 is vertically inserted into the span vertical pole bracket 2-6, and bolts pass through the holes provided in the span vertical pole bracket 2-6 and the bottom of the span vertical pole 2-3 to fix the two. Cross bars are provided between adjacent span vertical poles 2-3 to form a platform guardrail.

[0037] In this embodiment, the first crossbar 2-4 and the second crossbar 2-5 between the adjacent span vertical poles 2-3 are fixed by welding to form a platform guardrail. The first crossbar 2-4 and the second crossbar 2-5 between the spans can be made of square steel pipes, channel steels, angle steels, I-beams, round steels and other steel sections. It should be noted that in actual construction, one or more crossbars can be set between the adjacent span vertical poles 2-3, as long as the guardrail protection function is met. Wooden boards or steel plates are laid on the platform frame of the platform section under the beam and the platform frame of the platform section between the spans, which can be used as horizontal passages.

[0038] In the present invention, the cross-sectional dimensions of the inter-span longitudinal beam 2-1 are larger than those of the lower beam longitudinal beam 1-1. The lower beam longitudinal beam 1-1 is inserted into the adjacent inter-span longitudinal beam 2-1 and secured using detachable connectors, thereby securing the inter-span platform section 2 between the adjacent lower beam platform sections 1. Two parallel movable chains 3 are provided between adjacent lower beam uprights 1-3 and inter-span uprights 2-3, connecting the lower beam uprights 1-3 and the inter-span uprights 2-3. In this embodiment, the two parallel movable chains 3 are at the same height as the first lower beam crossbar 1-4 and the second lower beam crossbar 1-5, respectively.

[0039] This embodiment uses two lifting belts 4, each with a lifting device 5. The distance between the two lifting belts 4 is slightly larger than the width of the platform section 1 under the beam. The lifting device 5 can be a hand chain hoist or an electric hoist according to the actual working conditions.

[0040] This embodiment also provides a construction method for the multi-span assembled operating platform hung under the steel beam, which is specifically as follows:

[0041] S1: Hang two lifting straps 4 on each of the mutually parallel steel beams 7.

[0042] S2: Hang a hand hoist on each lifting belt 4.

[0043] S3: Hang a double chain sling under each hand hoist.

[0044] S4: Install the platform section 1 under the beam on both sides of the middle span of the steel structure: Assemble the platform frame and platform guardrail of the platform section 1 under the beam, and connect the two double-chain rigging on both sides of the platform section 1 under the beam to the four lug plates 1-7 of the platform section 1 under the beam to complete the hanging of the platform section 1 under the beam.

[0045] S5: Installing the mid-span platform section 2 of the steel structure: Assemble the platform frame and platform guardrails of platform section 2 and hoist it to the same height as platform section 1. Slightly shift platform section 1 to ensure sufficient clearance for inserting platform section longitudinal beam 1-1 into platform section longitudinal beam 2-1. Insert longitudinal beam 1-1 into longitudinal beam 2-1 to the specified length and then bolt it together.

[0046] S6: Install the beam platform section 1 and the span platform section 2 from the steel structure to both sides in sequence and connect them with bolts.

[0047] S7: Install the movable chain 3 between the guardrails of all the platform sections 1 under the beams and the platform sections 2 between the spans. The multi-span assembled operating platform hanging under the steel beam 7 is installed. Figure 4 shown.
