Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to an adjustable crossbar and scaffolding for scaffolding. Background Technology
[0002] Disc-lock scaffolding, also known as circular disc scaffolding, consists of uprights, horizontal bars, and diagonal braces. Each disc has eight holes: four small holes for horizontal bars and four large holes for diagonal braces. Horizontal and diagonal braces are connected using a pin-type connection, ensuring a secure bond between the horizontal and diagonal braces and the uprights. The joints of the horizontal and diagonal braces are manufactured according to the arc of the pipe diameter, making full contact with the upright. After tightening the pin, the structure experiences three points of force (two points above and below the joint and one point between the pin and the disc), providing a strong fixation and increasing structural strength. Horizontal bar joints are fully welded to the steel pipe body, while diagonal brace heads are rotatable joints, secured to the steel pipe body with rivets. The upright connection method eliminates the need for additional joint components, saving the trouble of lost materials and misorganization.
[0003] Therefore, it can be seen that traditional disc-lock scaffolding, because the horizontal bars are designed according to a fixed modular length, cannot be adapted to non-fixed modular lengths during scaffolding erection. In complex beam and slab construction environments, due to the various variations in beam and slab formwork spacing, if existing disc-lock scaffolding has already been used to support the formwork, then at locations of structural formwork that do not conform to the modular design, it is necessary to provide separate support for the structural formwork or to use other types of scaffolding that are not compatible with the disc-lock connection type. Both of these methods require a significant increase in the investment of construction facilities and materials, resulting in high construction difficulty, low efficiency, and construction safety risks. Utility Model Content
[0004] In view of the shortcomings of the prior art described above, the technical problem to be solved by this utility model is to provide an adjustable horizontal bar for scaffolding and scaffolding. The length of the adjustable horizontal bar is adjustable, so that it can be used at the position of structural templates that do not conform to the module, so as to support the uprights and improve construction efficiency and safety.
[0005] To solve the above-mentioned technical problems, this utility model provides an adjustable crossbar for scaffolding, which includes: a first member and a second member connected together, and two connectors for connecting to the disc buckle on the scaffolding. The two connectors are respectively located at the non-connected ends of the first member and the second member. Multiple connecting holes are distributed along the length direction on both the first member and the second member. The second member is stacked on top of the first member and connected to the first member by a connector passing through the connecting holes.
[0006] Preferably, the connector includes an insertion section that passes through the connection hole and a curved section that hangs on the first rod. The curved section is connected to the insertion section and can slide along the first rod.
[0007] Preferably, the first rod and the second rod are square tubes, channel steel or round tubes, and the first rod and the second rod are sleeved together.
[0008] Preferably, the connector is welded to the first rod or the second rod.
[0009] Preferably, the connector is detachably connected to the first rod or the second rod.
[0010] Preferably, the first or second rod is provided with reinforcing ribs or support rods.
[0011] Preferably, the connector includes a locking part for locking the disc buckle and a fixing pin, the fixing pin being inserted into a through hole through the locking part, and the opening width of the locking part matching the thickness of the disc buckle.
[0012] Preferably, a limiting part is provided at the overlapping point of the first rod and the second rod to prevent relative rotation of the first rod and the second rod.
[0013] This application also provides a scaffolding, comprising:
[0014] The scaffolding includes vertical and horizontal poles arranged in a longitudinal and transverse manner. The vertical poles are equipped with disc buckles, and the two ends of the horizontal poles are equipped with joints. The vertical poles and horizontal poles are fixedly connected through the joints and the disc buckles. The scaffolding also includes adjustable horizontal poles for scaffolding as described in any of the above claims. The two connectors of the adjustable horizontal poles are respectively fixedly connected to the disc buckles on the two vertical poles.
[0015] Preferably, the scaffolding further includes an inclined support member that connects the uprights and the horizontal bars at an angle.
[0016] As described above, the adjustable horizontal bar and scaffolding of this utility model have the following beneficial effects: the first and second members are connected by a connector, realizing the adjustment of the total length of the first and second members. This adjustable horizontal bar can be used at the position of the structural template that does not conform to the module on the scaffolding to realize the lateral support at this location, avoid the instability caused by the lack of support or other supports, and improve the construction safety. That is, the size of the scaffolding is adjustable. Moreover, it is directly connected to the disc buckle (i.e., disc buckle disc) on the upright through two joints by a pin, which improves the construction efficiency. Attached Figure Description

[0034] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.
[0035] It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings of this specification are merely for illustrative purposes and to aid those skilled in the art in understanding and reading the content disclosed herein. They are not intended to limit the implementation conditions of this utility model and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and objectives achieved by this utility model, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of implementation of this utility model.
[0036] like Figure 1 and Figure 2As shown, this utility model provides an adjustable crossbar for scaffolding, comprising: a first member 1 and a second member 2 connected together, and two connectors 5 for connecting to the scaffolding's disc buckles. The two connectors 5 are respectively located at the non-connected ends of the first member 1 and the second member 2. Multiple connecting holes 3 are distributed along the length direction on both the first member 1 and the second member 2. The second member 2 is stacked on top of the first member 1 and connected to the first member 1 by a connector 4 passing through the connecting holes 3. The adjustable crossbar of this embodiment has an adjustable total length and can be used at positions on scaffolding that do not conform to the modular structure, achieving stable support. Its length adjustment is easy to achieve; simply sliding the first member and the second member through the connector into the aligned connecting holes achieves locking and fixation.
[0037] As a preferred embodiment of the above-mentioned connector, see Figure 3 As shown, the connector 4 includes an insertion section 42 that passes through the connection hole and a curved section 41 that hangs on the first rod 1. The curved section 41 connects with the insertion section 42 and can slide along the first rod 1. In this embodiment, the connector is hung on the first rod 1 by the curved section 41, preventing the connector from falling off when adjusting the length of the adjustable crossbar. The connector 4 can be formed by bending steel bars or steel strips, etc. More preferably, the bending dimension of the curved section 41 matches the outer peripheral dimension of the first rod 1 to further prevent it from falling off.
[0038] The aforementioned first member 1 and second member 2 are square tubes, channel steel, or round tubes, and are nested together. The tubular steel structure of the first and second members provides more stable support, and ideally, their material should match that of the uprights and horizontal bars on the scaffold. Furthermore, using square tubes, channel steel, or round tubes increases the resilience of the adjustable horizontal bars, preventing bending when they are fixed.
[0039] The aforementioned connector 5 is welded to the first rod 1 or the second rod 2, resulting in a more stable structure. Connector 5 can also be rotatably connected to the first rod 1 or the second rod 2, facilitating installation and allowing for rotational implementation.
[0040] To increase support and stability, the first member 1 or the second member 2 is provided with reinforcing ribs or support rods.
[0041] See Figure 2 As shown, the connector 5 includes a locking part 51 for locking the disc buckle and a fixing pin 52. The fixing pin 52 passes through the through hole of the locking part 51, and the opening width of the locking part 51 matches the thickness of the disc buckle (i.e., the disc buckle disc on the upright).
[0042] As a preferred embodiment, a limiting part is provided at the overlapping point of the first rod 1 and the second rod 2 to prevent relative rotation of the first rod and the second rod, so as to enhance the resistance to twisting and facilitate construction, and avoid the two rods rotating during adjustment, which would make it difficult to install the connecting parts.
[0043] like Figure 4 As shown, this application also provides a scaffolding, which includes:
[0044] The scaffolding includes vertical and horizontal poles 300 and horizontal bars 200 arranged longitudinally and laterally. The vertical poles 300 are equipped with snap fasteners, and the horizontal bars 200 have connectors at both ends. The vertical poles 300 and horizontal bars 200 are fixedly connected through the connectors and snap fasteners. It also includes adjustable horizontal bars 100 for scaffolding as described in any of the preceding embodiments. Two connectors in the adjustable horizontal bar 100 are fixedly connected to snap fasteners on two vertical poles 200, respectively. The scaffolding of this embodiment is adjustable in size. It is erected using existing vertical and horizontal poles, and the adjustable horizontal bars are adjusted according to the actual distance and then installed on the vertical poles through connectors. This facilitates construction, provides strong support, and improves construction safety.
[0045] The aforementioned connectors and joints can have identical structures, facilitating connection to the disc buckles on the uprights. The aforementioned scaffolding also includes diagonal support members that connect the uprights and horizontal members at an angle.
[0046] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.
[0047] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
