Description

Technical Field

[0001] The invention relates to the technical field of scaffold assembly, in particular to a quick inverted square tube and round tube scaffold. Background Art

[0002] Scaffolding is mostly used for exterior wall construction, facade decoration and reinforced concrete engineering. It is a very common and important auxiliary device in the construction industry. So far, the construction of high-rise buildings and bridges has been inseparable from scaffolding. Scaffolding includes pipe fittings and fasteners (or scaffolding sleeves). Pipe fittings are generally used as the main body of the scaffolding, and fasteners are used to connect pipe fittings to form a stable scaffolding.

[0003] Existing scaffolds need to bear the weight of the human body as well as the weight of the building materials. In order to allow the scaffold to bear a larger weight, it is necessary to ensure the strength and stability of the connection between the fasteners and the pipe fittings. Bolts are often used for fixing to increase the stability of the fasteners. The efficiency of fastening by bolts is not high, which leads to a decrease in the efficiency of scaffold installation. Summary of the invention

[0004] The present invention aims to provide a quick inverted square tube and round tube scaffold, so as to provide a scaffold that can be quickly installed and improve the installation efficiency of the scaffold.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a quick inverted square tube and round tube scaffold, comprising a main body with an installation hole, a plurality of first connecting members evenly distributed along the circumference of the installation hole on the main body, and a plurality of second connecting members. During installation, the second connecting members are invertedly inserted into the first connecting members, the first connecting members and the second connecting members are matched with each other in a taper, and a support member for connecting the square tube is installed on the second connecting member.

[0006] The principle and beneficial effects of the present invention are as follows: (1) The main body is welded or bolted to the supporting tube of the scaffold through the mounting holes to form the basic structure of the scaffold. The main body is evenly distributed with first connecting members, and the gravity acting on the main body is dispersed through multiple first connecting members, thereby improving the strength and stability of the main body.

[0007] (2) A support member is installed on the second connecting member, and the support member supports the square tube, thereby increasing the strength of the square tube and the load-bearing capacity of the square tube, and reducing the probability of the square tube being easily deformed. In this solution, the square tube is supported by the support member, and the contact area between the square tube and the operator's feet is larger, which overcomes the problem of the small contact area between the existing round tube and the human foot, and is more conducive to the operator's stepping and placing construction materials, so that the surface of the square tube is similar to the ground, thereby providing the operator with a more solid working environment.

[0008] (3) During installation, the second connector is inserted upside down into the first connector and the taper is matched, so that the second connector can be quickly installed on the first connector, thereby improving the installation efficiency of the square tube, thus reducing the use of bolts and welding fixation, and reducing the cost of scaffolding. During installation, the second connector is inserted upside down into the first connector. When the square tube is subjected to gravity, the friction between the first connector and the second connector gradually increases, further increasing the stability of the first connector and the second connector.

[0009] Furthermore, the first connecting member includes a first protrusion and a second protrusion, a distance is left between the first protrusion and the second protrusion, the longitudinal section of the first protrusion is fishtail-shaped, the width of the fishtail-shaped top surface gradually increases from top to bottom, and the cross-section of the first protrusion is trapezoidal.

[0010] Beneficial effect: The first protrusion cooperates with the second connector to achieve the purpose of taper cooperation. The second protrusion is provided to reduce the distance between the body and the second connector, increase the friction between the second connector and the second protrusion, and further improve the stability of the second connector when being inverted.

[0011] Furthermore, a connecting hole is formed on the second connecting member, the longitudinal section of the connecting hole is in a fishtail shape, the width of the top surface of the fishtail shape gradually increases from top to bottom, and the cross section of the connecting hole is a trapezoid.

[0012] Beneficial effect: The first protrusion is stably installed in the connecting hole by matching the taper of the connecting hole and the first protrusion, which is convenient for the installation of the first protrusion. At the same time, the first protrusion is limited to improve the installation stability of the second connecting member. The longitudinal section of the first protrusion is fishtail-shaped with a small upper part and a large lower part. When the first protrusion is subjected to the force of the second connecting member, the first protrusion and the second connecting member will be more and more tightly matched. In addition, since the lower part of the fishtail shape is large and the force bearing capacity is strong, the overall support capacity and strength of the scaffolding are enhanced. In addition, since the cross-section of the first protrusion is trapezoidal, the tensile strength of the first protrusion and the second connecting member can be increased by the trapezoidal shape.

[0013] Furthermore, a pin hole is formed at the bottom of the second connecting member, and a pin shaft is detachably connected to the pin hole.

[0014] Beneficial effect: When the operator places construction materials on the square tube, the square tube will be subjected to a certain impact, causing the square tube to slide upward under the reaction force, and the second connecting piece is locked by the pin shaft to prevent the second connecting piece from sliding and buffer the force applied to the second connecting piece.

[0015] Furthermore, a clamping protrusion is provided on the second connecting member, and the width of the clamping protrusion is equal to the width of the spacing.

[0016] Beneficial effect: When the second connecting member is installed on the first connecting member, the clamping protrusion extends into the distance between the first protrusion and the second protrusion. Under the action of friction, the second connecting member is clamped on the first connecting member, thereby improving the installation stability of the second connecting member.

[0017] Furthermore, the diameter of the mounting hole is 30 mm to 150 mm.

[0018] Beneficial effect: The main body can be installed on the supporting pipes within the diameter range of 30mm to 150mm, so it can adapt to various types of supporting pipes.

[0019] Furthermore, the cross section of the support member is rectangular.

[0020] Beneficial effect: The cross section of the support is rectangular, so that the square tube can be sleeved on the support. Compared with the circular support, the rectangular support can not only fit the square tube better, but also increase the contact area between the support and the square tube. The rectangular support has a strong load-bearing capacity, which is convenient for the installation and welding of the square tube on the support, and improves the installation efficiency of the square tube.

[0021] Furthermore, the first protrusion and the second protrusion are integrally formed, and the second protrusion and the first protrusion are integrally formed.

[0022] Beneficial effect: Since the first connecting member is subjected to a large force, if welding is adopted, the weld is prone to fatigue failure or even breakage, which leads to a decrease in the stability and strength of the first connecting member. The first protrusion and the second protrusion are integrally formed to ensure the overall stability of the first connecting member. When installing the scaffold, since the first protrusion and the second protrusion are integrally formed, the strength is high, the safety factor of the scaffold is improved, and the scaffold is made more solid.

[0023] Furthermore, the clamping protrusion and the second connecting member are integrally formed.

[0024] Beneficial effect: The second connecting piece and the clamping protrusion are integrally formed, which has greater strength, is easier to manufacture, and reduces production costs compared to welding.

[0025] Furthermore, the number of the first connecting members is at least four.

[0026] Beneficial effect: Since the first connecting members are evenly distributed on the main body along the circumference of the mounting hole, the forces acting on the main body are dispersed through the four connecting members, thereby improving the supporting capacity of the main body.

[0036] The following is further described in detail through specific implementation methods:

[0037] The reference numerals in the drawings of the specification include: body 1, first protrusion 11, second protrusion 12, second connecting member 2, clamping protrusion 21, connecting hole 22, supporting member 23, pin shaft 24, square tube 3, second supporting member 4, slide plate 41, top shaft 42, spring 43, bubble membrane 44.

[0038] Embodiment 1:

[0039] Basically as attached Figure 1 As shown, the quick inverted square tube and round tube scaffolding includes a main body 1. A mounting hole with a circular cross section is opened in the middle of the main body 1. The diameter of the mounting hole is 30-150 mm. In this embodiment, the diameters are 30 mm, 150 mm, 40 mm, 50 mm, etc. In this embodiment, 30 mm is selected as an example. The main body 1 is provided with four first connecting members evenly distributed along the circumference of the mounting hole. The first connecting member includes a first protrusion 11 and a second protrusion 12. The second protrusion 12 is integrally formed with the first protrusion 11, and the second protrusion 12 is integrally formed with the main body 1. A spacing is left between the first protrusion 11 and the second protrusion 12. Combined with the attached Figure 2 and attached Figure 3As shown, the longitudinal section of the first protrusion 11 is fishtail-shaped, the width of the fishtail top surface gradually increases from top to bottom, the lower area of ​​the fishtail is larger than the upper area, increasing the bearing strength and tensile strength of the first protrusion, and the cross-section of the first protrusion 11 is trapezoidal.

[0040] The quick inverted square tube and round tube scaffold also includes a second connecting member 2, which has a connecting hole 22. Figure 4 and attached Figure 5 As shown, the longitudinal section of the connecting hole 22 is fishtail-shaped, and the width of the top surface of the fishtail shape gradually increases from top to bottom. The connecting hole 22 is tapered with the first protrusion 11, and the cross section of the connecting hole 22 is trapezoidal. A clamping protrusion 21 is integrally formed on the second connecting member 2. The width of the clamping protrusion 21 is equal to the width of the spacing. A support member 23 is integrally formed on the second connecting member 2, and the longitudinal section of the support member 23 is rectangular. A pin hole is opened at the lower part of the second connecting member 2, and a pin shaft 24 is detachably installed in the pin hole in a clamping manner.

[0041] The specific implementation process is as follows:

[0042] The installation steps of quick inverted square tube and round tube scaffolding are as follows: Step 1: As shown in the attached Figure 5 , Attachment Figure 6 and attached Figure 7 As shown, the operator first removes the pin 24 from the second connecting member 2, sets the square tube 3 with a rectangular cross section on the support member 23, and welds the square tube 3 and the support member 23 together, so that the square tube 3 and the second connecting member 2. Under the support of the support member 23, the square tube 3 enhances the support strength of the square tube 3 and improves the load-bearing capacity of the square tube 3, so that the operator can walk on the square tube 3 more steadily. In the prior art, round tubes are used for the construction of scaffolding. Compared with the square tube 3, the square tube 3 has a larger contact area with the human body, and the operator has a larger area to step on, which makes the operator feel more secure.

[0043] Step 2: Since the second connector 2 has a fishtail-shaped connection hole 22 with a width gradually increasing from top to bottom, and the longitudinal section of the first protrusion 11 is a fishtail-shaped shape with a width gradually increasing from top to bottom, the second connector 2 is inserted from top to bottom onto the first protrusion 11, clamped by taper matching, and the clamping protrusion 21 extends into the spacing. Since the clamping protrusion 21 is equal to the width of the spacing, the spacing and the clamping protrusion 21 further clamp the second connector 2 on the body 1. In this way, it is not necessary to fix the second connector 2 by bolts or welding, which reduces the steps of scaffolding installation and improves the efficiency of scaffolding construction. Since the cross-sections of the first protrusion 11 and the connection hole 22 are trapezoidal, the tensile strength of the first connector and the second connector can be increased by trapezoidal matching.

[0044] Step 3: After the second connecting member 2 is inserted upside down on the body 1, the pin 24 is inserted into the pin hole of the second connecting member 2. When the gravity on the square tube 3 is large, the support of the body 1, the first connecting member, the second connecting member 2, and the support member 23 is used to improve the load-bearing capacity of the square tube 3.

[0045] Since the first connector and the second connector 2 are tapered and inverted, the square tube 3 is more tightly clamped and more stable when pushing the second connector 2 downward, and the longitudinal section of the first protrusion 11 is fishtail-shaped, so it has greater strength. When a heavy object is placed on the square tube 3, it has a certain impact on the square tube 3, and the square tube 3 will be subjected to a reverse force, and the square tube 3 will slide upward with the second connector 2, and the pin 24 will slide upward with the second connector 2, and the second connector 2 will be against the first protrusion 11. In this way, the second connector 2 and the square tube 3 are limited by the pin 24, which prevents the second connector 2 from being separated from the first connector, thus ensuring the safety performance of the scaffolding. At the same time, when the force on the second connector 2 and the square tube 3 acts on the pin 24, the pin 24 provides a certain buffer to the second connector 2.

[0046] Embodiment 2:

[0047] The difference between the second embodiment and the first embodiment is that, as shown in the attached Figure 8 and attached Fig. 9 As shown, a second support member 4 is arranged inside the support member 23, and the second support member 4 includes a main shaft welded on the second connecting member 2, and a slideway running through the upper and lower parts of the main shaft is opened inside the main shaft, and a support assembly is arranged at the upper and lower parts of the slideway, and the support assembly includes a top shaft 42 and a slide plate 41, the slide plate 41 is welded to the bottom of the top shaft 42, the top shaft 42 is welded to the support member 23, the slide plate 41 is located in the slideway and the slide plate 41 is vertically slidably connected to the slideway, and a spring 43 is arranged between the slide plates 41 of the two support assemblies, and the two ends of the spring 43 are respectively welded to the slide plate 41. A bubble film 44 is bonded to the outside of the main shaft, and an air hole connected to the bubble film 44 is opened on the main shaft, and the air hole is located between the two slide plates 41. The volume between the two slide plates 41 is three times the volume of the bubble film 44, so as to ensure that the gas between the slide plates 41 enters the bubble film 44 and can break the bubble film 44.

[0048] The specific implementation process is as follows:

[0049] When the square tube 3 is subjected to the gravity of the human body or building materials, the second support member 4 and the support member 23 support the square tube 3 and the second connecting member 2, thereby improving the load-bearing capacity of the square tube 3; and when the square tube 3 is impacted, the support components at both ends of the second support member 4 buffer the square tube 3, thereby improving the stability of the square tube 3.

[0050] If the weight of the heavy object exceeds the load-bearing range of the square tube 3, the square tube 3 will deform and squeeze the second support member 4, so that the slides 41 at one or both ends of the second support member 4 slide toward the middle of the main shaft and squeeze the gas between the slides 41 into the bubble membrane 44, the bubble membrane 44 expands, and then the bubble membrane 44 bursts. The sound produced by the bursting reminds the operator that the square tube 3 has been deformed and needs to be dealt with in time, thereby further ensuring the safety of the operator.

[0051] The above are only preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention, which should also be regarded as the protection scope of the present invention, and will not affect the effect of the implementation of the present invention and the practicality of the patent. The technology, shape, and structural parts omitted in the present invention are all well-known technologies.
