Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for building construction, in particular to a truss-type supporting beam for a scaffold and a connecting structure thereof. Background Art

[0002] In frame-system houses and industrial buildings, scaffolding is widely used in construction. In the process of adopting scaffolding construction technology, how to save materials and labor more effectively while ensuring safe construction has always been the research direction.

[0003] In construction applications, scaffolding often needs to build temporary operating platforms, anti-smashing sheds, safety passages, external scaffolding and other platform structures. The current conventional practice is to connect the crossbar between the two vertical poles of the scaffolding support structure, and directly lay the scaffolding planks on the crossbar to form a platform structure. When a large-width platform structure needs to be built, the span of the crossbar is also large, which cannot meet the requirements of load-bearing safety and stability. At this time, it is usually solved by increasing the number of vertical poles connected to the crossbar. However, increasing the vertical poles not only increases the input of materials and labor, resulting in low construction efficiency and waste of resources, but also the increased vertical poles will occupy the space under the platform structure, which cannot meet the need to reserve space for setting up labor or vehicle passages under the platform structure. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a truss support beam for scaffolding and a connection structure thereof which can reduce materials and labor, lower costs and improve construction efficiency while meeting the requirements of a large-span platform structure.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A truss support beam for a scaffold comprises an upper crossbar and a lower crossbar which are arranged side by side and at intervals, a plurality of connecting rods are connected between the upper crossbar and the lower crossbar, and connecting heads for connecting to a scaffold neutral rod are respectively provided at both ends of the upper crossbar and the lower crossbar.

[0007] As a further improvement of the above technical solution:

[0008] The connecting rod comprises a plurality of vertical webs which are perpendicular to the upper cross bar and the lower cross bar, and two ends of each vertical web are respectively connected and fixed to the upper cross bar and the lower cross bar.

[0009] The connecting rod also includes a plurality of diagonal bracing web members which are arranged at an acute angle relative to the vertical web members, and two ends of each diagonal bracing web member are respectively connected and fixed to the upper cross bar and the lower cross bar.

[0010] Two diagonal bracing web members and two vertical web members are connected between the upper cross bar and the lower cross bar, and the two diagonal bracing web members are located between the two vertical web members.

[0011] One diagonal brace web member extends obliquely from the upper cross bar toward one end of the lower cross bar, and another diagonal brace web member extends obliquely from the upper cross bar toward the other end of the lower cross bar.

[0012] The upper cross bar and the lower cross bar have the same length and are aligned at both ends. A vertical web member and a diagonal brace web member are respectively provided on both sides of the midpoint line of the upper cross bar and the lower cross bar, and the vertical web members and the diagonal brace web members on both sides of the midpoint line of the upper cross bar and the lower cross bar are symmetrically arranged relative to the midpoint line of the upper cross bar and the lower cross bar.

[0013] The upper cross bar, the lower cross bar, the vertical web members and the diagonal bracing web members are all steel pipes.

[0014] The connecting head is a crossbar joint matched and connected with the connecting plate on the middle pole of the disc-type scaffolding.

[0015] A connection structure comprises two columns, between which the above-mentioned scaffolding truss support beam is connected, and the connecting heads at both ends of the upper cross bar and the lower cross bar in the scaffolding truss support beam are respectively connected to the two columns.

[0016] Compared with the prior art, the advantages of the utility model are:

It is a truss beam structure composed of a plurality of connecting rods connected by the upper cross bar and the lower cross bar. It has a very good load-bearing capacity and meets the load-bearing capacity, stability and safety requirements of the large-span platform structure. There is no need to increase the number of poles, which can reduce materials and labor, reduce costs, improve construction efficiency, and can meet the needs of reserving space for setting up labor or driving passages under the platform structure.

[0024] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Embodiment 1:

[0026] like Figure 1 As shown, the truss-type support beam for scaffolding of this embodiment comprises an upper crossbar 1 and a lower crossbar 2 arranged side by side and at intervals, a plurality of connecting rods are connected between the upper crossbar 1 and the lower crossbar 2, and connectors 3 for connecting with the scaffolding neutral pole are respectively provided at both ends of the upper crossbar 1 and the lower crossbar 2. The truss-type support beam for scaffolding can be connected to the scaffolding neutral pole through the connectors 3 at both ends of the upper crossbar 1 and the lower crossbar 2, and can be used for laying scaffolding boards to form a platform structure. It is a truss-type beam structure composed of a plurality of connecting rods connected by the upper crossbar 1 and the lower crossbar 2, and has a very good bearing capacity. When meeting the bearing capacity, stability and safety requirements of the large-span platform structure, there is no need to increase the number of poles, which can reduce materials and labor, reduce costs, and improve construction efficiency, and can meet the requirements of reserving space for setting up labor or vehicle passages under the platform structure.

[0027] In this embodiment, the connecting rod includes two vertical web members 4 perpendicular to the upper cross bar 1 and the lower cross bar 2, and the two ends of each vertical web member 4 are respectively connected and fixed to the upper cross bar 1 and the lower cross bar 2. The two ends of the vertical web members 4 are respectively connected and fixed to the upper cross bar 1 and the lower cross bar 2 and are perpendicular to the upper cross bar 1 and the lower cross bar 2, which can effectively transmit the supporting force, use less materials, and help reduce costs.

[0028] In this embodiment, the connecting rod further comprises two diagonal bracing members 5 arranged at an acute angle relative to the vertical bracing members 4, and the two ends of each diagonal bracing member 5 are respectively connected and fixed to the upper cross bar 1 and the lower cross bar 2. The diagonal bracing members 5 have a better load transfer capacity, and combined with the vertical bracing members 4, can greatly improve the overall stability and load-bearing capacity of the truss support beam for scaffolding.

[0029] In this embodiment, the two diagonal bracing web members 5 are located between the two vertical web members 4, which can reduce the cantilever lengths at both ends of the upper cross bar 1 and the lower cross bar 2, thereby ensuring a high load-bearing capacity.

[0030] In this embodiment, one diagonal brace member 5 extends obliquely from the upper cross bar 1 toward one end of the lower cross bar 2, and another diagonal brace member 5 extends obliquely from the upper cross bar 1 toward the other end of the lower cross bar 2, which can further improve the overall stability and load-bearing capacity of the truss support beam for scaffolding.

[0031] In this embodiment, the lengths of the upper crossbar 1 and the lower crossbar 2 are consistent and the two ends are aligned, a vertical web member 4 and a diagonal web member 5 are respectively provided on both sides of the midpoint connection line of the upper crossbar 1 and the lower crossbar 2, and the vertical web members 4 and the diagonal web members 5 on both sides of the midpoint connection line of the upper crossbar 1 and the lower crossbar 2 are symmetrically arranged relative to the midpoint connection line of the upper crossbar 1 and the lower crossbar 2. That is, the truss-type support beam for scaffolding is a symmetrical structure as a whole, its force is balanced, and its bearing capacity and structural stability are better.

[0032] In other embodiments, the number of vertical web members 4 and diagonal web members 5 is not limited to two, and the connection and arrangement positions may also be different from that in this embodiment.

[0033] In this embodiment, the upper cross bar 1, the lower cross bar 2, the vertical web members 4 and the diagonal bracing web members 5 are all steel pipes, which are easy to obtain, light in weight and low in cost.

[0034] In this embodiment, the connector 3 is a crossbar connector that matches and connects with the connecting plate on the middle pole of the disc-type scaffolding, so as to be directly assembled into the disc-type scaffolding. The connecting plate on the middle pole of the disc-type scaffolding and the crossbar connector that matches and connects with it are both prior art, and specific reference can be made to the existing disc-type scaffolding.

[0035] Embodiment 2:

[0036] like Figure 2 and Figure 3 As shown, a connection structure includes two columns 6, between which the truss-type support beam for scaffolding of Example 1 is connected, and the connectors 3 at both ends of the upper crossbar 1 and the lower crossbar 2 in the truss-type support beam for scaffolding are respectively connected to the two columns 6. Specifically, the two columns 6 are columns with connecting plates in a disc-type scaffolding, and the connecting heads 3 are connected to the connecting plates on the columns by means of a latch, that is, the connecting heads 3 are connected to the connecting plates on the columns by means of a disc-type connection structure in an existing scaffolding.

[0037] A combination of multiple connection structures of the present embodiments can be used to directly lay scaffolding boards to form platform structures such as operating platforms, anti-smashing sheds, safety passages, and external scaffoldings. Since the connection structure of the present embodiment adopts the truss support beam for scaffolding of Example 1, it also has the advantages of the truss support beam for scaffolding.

[0038] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. For those skilled in the art, improvements and changes obtained without departing from the technical concept of the present invention should also be regarded as the protection scope of the present invention.
