Description

Technical Field

[0001] The utility model belongs to the technical field of civil construction support, in particular to a support device for civil construction. Background Art

[0002] In the process of civil construction, support devices have always played a pivotal role as an important tool to ensure the stability of buildings and construction safety. With the continuous development of construction technology, traditional support devices such as wooden supports and steel pipe fastener scaffolding have gradually failed to meet the construction needs of modern housing construction in terms of efficiency, safety and environmental protection.

[0003] The disc-type scaffold is a new type of scaffolding. The connection method of its vertical poles, cross bars and diagonal poles is to use the pins at both ends of the cross bars and diagonal poles and the connecting plates of the vertical poles for connection. When installing, just align the joints of the cross bars and diagonal poles with the connecting plate position, then insert the pins into the holes of the connecting plate by hand and pass through the bottom of the joints, and then hit the top of the pins with a hammer to make the arc surface on the joints of the cross bars and diagonal poles tightly combined with the vertical poles. The tightness of the pins is directly related to the reliability of the rod connection and thus affects the overall stability of the scaffolding body.

[0004] According to the operating specifications, when erecting scaffolding, it is advisable to use a hammer of no less than 0.5kg to hit the top surface of the pin for no less than 2 times until the pin is tightened. After the pin is tightened, it should be hit again, and the amount of sinking of the pin should not exceed 3mm. However, in actual implementation, it is difficult for both operators and managers to determine the exact amount of sinking with the naked eye. If the amount of sinking of the pin does not meet the standard, it will cause instability in the rod connection and affect the life safety of construction workers. Utility Model Content

[0005] The utility model aims to provide a supporting device for civil construction, which can facilitate construction workers to judge whether the sinking amount of the latch meets the standard.

[0006] The support device for civil construction comprises a vertically arranged upright pole, a connecting plate is installed on the upright pole, four first connecting holes are opened on the connecting plate, which are connected up and down and distributed at equal intervals along the circumference thereof, a cross bar is connected to the connecting plate, the cross bar and the connecting plate are connected by a connecting head, a slot is opened on the connecting head for inserting the connecting plate, a pin hole connected up and down is opened on the connecting head corresponding to the slot, and the same pin is passed through the pin hole and the first connecting hole; a plurality of positioning blocks are arranged on the top and bottom of the connecting plate, which are distributed at equal intervals along the circumference thereof, the positioning blocks are fixed between the upright pole and the connecting plate, and positioning grooves for inserting the positioning blocks are opened on the connecting head on the upper and lower sides of the corresponding connecting plate; when the pin is locked in the pin hole and the first connecting hole, the connecting head fits on the side wall of the upright pole.

[0007] Furthermore, the first connecting hole and the pin hole are both rectangular in structure, and the left hole walls of both are inclined surfaces that are wider at the top and narrower at the bottom.

[0008] Furthermore, the latch has a right-angled trapezoidal structure, and the inclined surface of the right-angled trapezoid is located on one side of the vertical pole.

[0009] Furthermore, the side wall of the connector close to the vertical pole is in the form of an arc surface, and the center of the arc surface is located on the center line of the vertical pole.

[0010] Furthermore, a second connection hole is provided between every two adjacent first connection holes, and the second connection holes are opened on the connection plate and communicated with each other vertically.

[0011] Furthermore, the upright pole and the connecting plate are integrally formed.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model wedges the latch into the pin hole and determines whether the sinking amount of the latch meets the standard by relying on the contact between the connecting head and the vertical rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0020] Example

[0021] A supporting device for civil construction described in this embodiment, such as Figures 1 to 3As shown, it includes a vertically arranged upright pole 1, on which a connecting plate 3 is installed, and the upright pole 1 and the connecting plate 3 are integrally formed; thus, the connecting plate 3 and the upright pole 1 have better structural strength; this embodiment only considers the case where a single upright pole 1 and a cross bar 4 are connected; the upright pole 1 and the connecting plate 3 are both made of carbon steel or aluminum alloy;

[0022] The connection disk 3 is provided with four first connection holes which are connected vertically and are evenly spaced along its circumference; a second connection hole is provided between each two adjacent first connection holes, and the second connection hole is provided on the connection disk 3 and is connected vertically;

[0023] The connecting plate 3 is connected with a cross bar 4, and the cross bar 4 is connected to the connecting plate 3 through a connecting head 5; during the construction process, the first connecting hole is used for the connecting head 5 on the cross bar 4, and the second connecting hole is used for the diagonal rod connection (omitted in the drawings of the specification); the cross bar 4 is made of aluminum alloy or carbon steel;

[0024] The four first connection holes are distributed in four directions, front, back, left, and right. That is, one connection plate 3 can be connected to four connection heads 5 at the same time.

[0025] The connector 5 is provided with a slot for inserting the connection plate 3, and a pin hole communicating with each other from top to bottom is provided on the connector 5 corresponding to the slot. The pin hole is wide at the top and narrow at the bottom, and the slot is located in the middle of the connector 5. Figure 1 For example, the connector 5 is located on the right side of the upright pole 1, and the slot is opened on the left side wall of the connector 5, and the width of the slot can just be inserted into the connecting plate 3, that is, the thickness of the connecting plate 3 is slightly smaller than the width of the slot;

[0026] The same plug pin 6 is installed in the pin hole and the first connection hole, and the first connection hole is wide at the top and narrow at the bottom; the plug pin 6 is wide at the top and narrow at the bottom and is inclined; the first connection hole and the pin hole are both rectangular, and the left side hole walls of both are inclined surfaces that are wide at the top and narrow at the bottom; the left side wall of the plug pin 6 is a wedge surface that is wide at the top and narrow at the bottom, and the plug pin 6 is generally made of high-strength, corrosion-resistant, and wear-resistant steel material;

[0027] When in use, the latch 6 is inserted from the upper opening of the pin hole, passes through the first connecting hole and then passes out from the lower end of the pin hole. The latch 6 is locked in the pin hole and the first connecting hole, and the connector 5 is attached to the side wall of the upright pole 1. Figure 1 As shown, the latch 6 is in a right-angled trapezoidal structure, the inclined surface of the right-angled trapezoid is located on one side of the vertical pole 1, and the inclined surface is also the left side wall of the latch 6. The right side wall of the latch 6 is in a vertical state, and its left side wall is inclined from top to left, bottom to right.

[0028] When in use, as the hammer strikes the top surface of the latch 6, the latch 6 sinks along the pin hole, and the connector 5 is driven by the wedge surface of the latch 6 to approach the upright pole 1 until the connector 5 fits against the side wall of the upright pole 1, indicating that the latch 6 has been brought in completely, thereby judging the amount of sinking of the latch 6.

[0029] The side wall of the connector 5 close to the vertical pole 1 is in an arc shape, and the center of the arc is located on the center line of the vertical pole 1, so that the connector 5 fits better with the vertical pole 1, and the stability of the structure between the cross bar 4 and the vertical pole 1 is increased to a certain extent.

[0030] like Figure 1 and Figure 3 As shown, the top and bottom of the connection plate 3 are provided with a plurality of positioning blocks 2 distributed at equal intervals along the circumference thereof, and there are 8 positioning blocks 2, corresponding to the four first connection holes and the second connection holes respectively, and the 8 positioning blocks 2 are all made of carbon steel;

[0031] The positioning block 2 is fixed between the upright pole 1 and the connecting plate 3. During production, the positioning block 2 can be fixed between the upright pole 1 and the connecting plate 3 by welding. Positioning grooves for inserting the positioning block 2 are provided on the connector 5 at the upper and lower sides of the corresponding connecting plate 3.

[0032] During installation, the positioning groove on the upper side of the connecting head 5 corresponds to the positioning block 2 located on the upper side of the connecting disk 3, and the positioning groove on the lower side of the connecting head 5 corresponds to the positioning block 2 located on the lower side of the connecting disk 3; after the pin 6 locks the connecting head 5, the connecting head 5 fits against the vertical pole 1, and the positioning block 2 just enters the positioning groove and adapts to it, further limiting the possible deviation and looseness of the connecting head 5, making the overall erection of the scaffolding more stable; in addition, the positioning block 2 also acts as an inner plate, increasing the structural strength between the connecting disk 3 and the vertical pole 1.

[0033] In actual use:

[0034] The latch 6 is inserted into the pin hole and the first connecting hole, and as the latch 6 sinks into the pin hole, the connector 5 slowly approaches the pole 1 until the connector 5 rests against the pole 1 and the positioning block 2 enters the positioning groove, thereby judging whether the sinking amount of the latch 6 is wedged in place and meets the standard.
