Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a scaffold for building construction. Background Technology

[0002] In the field of construction engineering, scaffolding, as a temporary support and working platform, is widely used in house construction, bridge construction, equipment installation, and interior and exterior decoration. Its basic structure typically includes uprights, horizontal bars, diagonal braces, and connectors.

[0003] Currently, common scaffolding on the market, especially coupler-type steel pipe scaffolding and some socket-type scaffolding, has some significant shortcomings in the erection process.

[0004] Firstly, regarding the installation of horizontal bars, traditional coupler-type scaffolding requires individual couplers, such as right-angle couplers and swivel couplers, to fix the horizontal bars to the vertical bars. This connection method is cumbersome, requiring workers to tighten each bolt individually. This is not only time-consuming and labor-intensive, but the tightness of the bolts also depends on the worker's operation, making it easy for the connection to loosen due to inadequate tightening, posing a safety hazard. Although some quick-release scaffolding uses a socket structure, it requires the insertion of fixing pins, which is not only cumbersome to install, but the fixing pins, being separate parts, are also prone to being lost.

[0005] Secondly, the length and angle of existing diagonal braces are usually fixed, and specific diagonal braces are usually required for scaffolding of different sizes, which is not convenient for general use.

[0006] Therefore, existing scaffolding technologies need improvement in terms of horizontal bar installation efficiency, diagonal brace adaptability, and installation accuracy. Utility Model Content

[0007] To overcome the shortcomings mentioned above, this utility model aims to provide a construction scaffold that enables quick, simple, and reliable installation of horizontal members, while allowing for flexible adjustment of the length and installation angle of diagonal braces to adapt to different construction conditions and improve erection efficiency. The objective of this utility model is achieved through the following technical solution: A type of scaffolding for building construction includes uprights, horizontal bars, and diagonal bars.

[0008] Several connecting plates are fixed at intervals on the outer side of the upright. The connecting plates are provided with connecting pin holes. The length of the upright between two adjacent connecting plates is adjustable. The upper and lower ends of the upright are respectively connected to a top support and a bottom support.

[0009] The crossbar is provided with quick connectors at both ends. Each quick connector includes a connector seat, a movable pin, and a spring. The connector seat is fixed to the end of the crossbar and has a through hole in the vertical direction. The movable pin is movably inserted into the through hole through the spring. The movable pin can be selectively inserted into the connecting pin hole. The quick connector is connected to the connecting plate through the movable pin.

[0010] The diagonal brace is inclined between two adjacent uprights and located between two adjacent connecting plates. The two ends of the diagonal brace are detachably connected to the uprights via ball joint assemblies.

[0011] Furthermore, the quick connector includes two connector seats arranged vertically opposite each other, two movable pins symmetrically arranged with beveled surfaces on opposite sides, the two beveled surfaces forming cuts facing the connecting disc, and the two movable pins being inserted from the upper and lower ends of the connecting pin hole respectively.

[0012] Furthermore, both the upper and lower ends of the through hole of the connector seat are fixed with limiting inner rings. The movable pin includes a pin body and a stop. The beveled surface is provided at the end of the pin body away from the stop. A limiting outer ring is fixed on the outside of the pin body and close to the stop. The limiting outer ring can selectively abut against the two limiting inner rings.

[0013] Furthermore, the spherical universal joint assembly includes a ball head component, a ball groove component, and a cover. The ball head component and the ball groove component are threadedly connected to the diagonal rod and the upright rod, respectively. The ball head component and the ball groove component are adapted to each other. The cover is movably sleeved on the outside of the ball head component and threadedly connected to the ball groove component.

[0014] Furthermore, the length of the diagonal bar is adjustable.

[0015] Furthermore, the inclined rod includes a first fixed rod, a first sleeve, and a first screw. The first fixed rod and the first screw are respectively disposed on both sides of the first sleeve. The first fixed rod is fixedly connected to the first sleeve, and the first screw is partially inserted into the first sleeve and threadedly connected to the first sleeve.

[0016] Furthermore, the upright includes multiple sets of second fixed rods, second sleeves and second screws arranged in sequence. The connecting plate is fixed to the outer side of the middle part of the second fixed rod, the second sleeve is fixed to the upper end of the second fixed rod, the second screw is fixed to the lower end of the second fixed rod, and the second screw is partially inserted into the second sleeve and threadedly connected to the second sleeve.

[0017] Furthermore, a mounting base is provided at the end of the spherical universal joint assembly away from the inclined rod, the mounting base is fixed to the second fixed rod, and the ball groove component is threadedly connected to the mounting base.

[0018] Compared with the prior art, the beneficial effects of this utility model are: The scaffolding for construction in this invention features quick-connect couplings at both ends of the horizontal bars. These couplings allow for direct pushing of the couplings to insert the movable pins into the connecting pin holes on the connecting discs. This eliminates the need for external tools and additional fixing pins, effectively reducing the installation steps for the horizontal bars and improving their installation efficiency.

[0019] By installing spherical universal joint assemblies at both ends of the diagonal brace, the installation angle between the diagonal brace and the upright can be adjusted, thereby improving utilization. Attached Figure Description

Example

[0028] like Figures 1-6 As shown, the scaffolding used for construction in this embodiment includes uprights 1, horizontal bars 5, and diagonal bars 7.

[0029] Among them, several connecting plates 2 are fixed at intervals on the outer side of the upright 1. Four connecting pin holes are arranged in a circular array on the connecting plates 2. The length of the upright 1 between two adjacent connecting plates 2 is adjustable. The upper and lower ends of the upright 1 are respectively connected to the top support 3 and the bottom support 4.

[0030] Specifically, the upright 1 includes multiple sets of sequentially arranged second fixing rods 101, second sleeves 102, and second screws 103. The top of the uppermost second fixing rod 101 is connected to a top support 3, and the bottom of the lowermost second fixing rod 101 is connected to a bottom support 4. A connecting plate 2 is fixed to the outer side of the middle of the second fixing rod 101, the second sleeve 102 is fixed to the upper end of the second fixing rod 101, and the second screw 103 is fixed to the lower end of the second fixing rod 101. The second screw 103 is partially inserted into the second sleeve 102 and threadedly connected to it. This allows adjustment of the distance between adjacent connecting plates 2, thereby adjusting the length of the entire upright 1 to accommodate different installation positions. Furthermore, the threaded connection between the second screw 103 and the second sleeve 102 facilitates the overall installation and removal of the upright 1.

[0031] In this embodiment, quick connectors 6 are provided at both ends of the crossbar 5. Each quick connector 6 includes a connector base 601, a movable pin 602, and a spring 603. The connector base 601 is fixed to the end of the crossbar 5 and has a vertically oriented through hole. The movable pin 602 is movably inserted into the through hole via the spring 603. The movable pin 602 can be selectively inserted into a connecting pin hole. The quick connector 6 is connected to the connecting plate 2 via the movable pin 602. No other external tools or additional separate fixing pins are required, thus effectively reducing the installation steps of the crossbar 5 and improving its installation efficiency.

[0032] Preferably, the quick connector 6 includes two connector seats 601 arranged vertically opposite each other, and two movable pins 602 are symmetrically arranged with beveled surfaces on their opposite sides. The two beveled surfaces form cuts facing the connecting plate 2. Correspondingly, the edges of the upper and lower ends of the connecting plate 2 are beveled, so as to facilitate the insertion of the connecting plate 2 between the two movable pins 602, and thus facilitate the insertion of the two movable pins 602 from the upper and lower ends of the connecting pin hole respectively.

[0033] Specifically, both the upper and lower ends of the through hole of the connector seat 601 are fixed with limiting inner rings 604. The movable pin 602 includes a pin body and a stop. The beveled surface is set at the end of the pin body away from the stop. A limiting outer ring 605 is fixed on the outside of the pin body and close to the stop. The limiting outer ring 605 can selectively abut against the two limiting inner rings 604. In the initial state, the spring 603 is in a natural or compressed state, and the limiting outer ring 605 abuts against the limiting inner ring 604 away from the stop.

[0034] In this embodiment, the diagonal brace 7 is inclinedly disposed between two adjacent uprights 1 and between two adjacent connecting discs 2. Both ends of the diagonal brace 7 are detachably connected to the uprights 1 via ball joint assemblies 8. This allows for adjustment of the installation angle between the diagonal brace 7 and the uprights 1, improving utilization.

[0035] Specifically, the spherical universal joint assembly 8 includes a ball head component 801, a ball groove component 802, and a cover 803. The ball head component 801 and the ball groove component 802 are threadedly connected to the diagonal rod 7 and the upright rod 1, respectively. A universal ball head and a ball groove are respectively provided on the side of the ball head component 801 and the ball groove component 802 that are close to each other. The universal ball head and the ball groove are compatible with each other. The ball groove is a hemispherical groove. The cover 803 is provided with a limiting hole, and the inner diameter of the limiting hole is smaller than the ball diameter of the universal ball head. The cover 803 is movably sleeved on the outside of the ball head component 801 and threadedly connected to the ball groove component 802, thereby facilitating installation.

[0036] Preferably, the length of the diagonal rod 7 in this embodiment is adjustable. The diagonal rod 7 includes a first fixing rod 701, a first sleeve 702, and a first screw 703. The first fixing rod 701 and the first screw 703 are respectively disposed on both sides of the first sleeve 702, and the ends of the first fixing rod 701 and the first screw 703 away from the first sleeve 702 are threadedly connected to the ball joint component 801. The first fixing rod 701 is fixedly connected to the first sleeve 702, and the first screw 703 is partially inserted into the first sleeve 702 and threadedly connected to the first sleeve 702. A mounting seat 9 is provided at the end of the spherical universal joint assembly 8 away from the diagonal rod 7. The mounting seat 9 is fixed to the second fixing rod 101, and the ball groove component 802 is threadedly connected to the mounting seat 9. This allows for adjustment of the length of the diagonal rod 7, further improving the utilization rate of the diagonal rod 7. The threaded connection between the spherical universal joint assembly 8, the mounting seat 9, and the diagonal rod 7 also facilitates the installation and removal of the diagonal rod 7.
