Description

Technical Field

[0001] This invention belongs to the field of support technology, and in particular relates to an adjustable flat and curved surface support frame structure and its connection method. Background Technology

[0002] In most bridge construction operations in my country, full-span scaffolding technology is widely used due to its advantages such as simple process, low labor intensity, no need for large machinery for erection and dismantling, convenient loading and unloading of poles, and low equipment cost.

[0003] However, most current scaffolding technologies are applicable to planar structure construction. For structures with curved or sloping outer surfaces (such as the fish-belly beam structure of elevated bridges), there is a lack of reasonably designed and scientific support technologies. Reasonably designed and scientific support technologies can ensure construction safety, improve construction efficiency and save costs during construction, and can also indirectly improve a series of problems such as the impact of inadequate formwork support on the quality of concrete pouring. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable flat and curved support frame structure, which aims to solve the problems existing in the background art.

[0005] The present invention is implemented as follows: an adjustable flat and curved surface support frame structure, the structure comprising:

[0006] Top support surface, used to support the pouring surface;

[0007] A support surface, one side of which is connected to a top support surface via a fixed connecting rod, and the other side of which is connected to a top support surface via an adjustable connecting rod;

[0008] A support link is connected at the center of the lower side of the support surface;

[0009] One end of the fixed connecting rod is hinged to the top support surface, and the other end of the fixed connecting rod is rigidly connected to the support surface.

[0010] Preferably, the support surface is provided with a graduated groove for determining the position of the adjustable connecting rod.

[0011] Preferably, the adjustable connecting rod securely connects the top support surface to the support connecting rod through a graduated groove.

[0012] Preferably, the fixed link is connected to the support link through the extension line of the support surface.

[0013] Preferably, when the top support surface is subjected to force, the resultant force on the fixed connecting rod and the adjustable connecting rod is along the direction of the supporting connecting rod, and the supporting connecting rod transmits the resultant force to the node of the full-span scaffold.

[0014] Preferably, the position of the adjustable link is calculated using the following formula:

[0015] α + Δα + β + γ = 180° (1)

[0016] sinβ / (L3+L4)=sinγ / L2 (2)

[0017] L / (L4cosγ1)=tan(γ-γ1) (3)

[0018] L=tan{arcsec[sec(α+Δα)-L2 / (L3+L4)sin(α+Δα)]-α-Δα-γ1}L4cosγ1 (4);

[0019] Wherein, Δα represents the change in α when the top support surface changes from horizontal support to curved inclined support;

[0020] β represents the angle between the adjustable connecting rod and the top support surface when the top support surface is a curved inclined surface support;

[0021] γ represents the angle formed by the extension of the adjustable connecting rod and the support surface when the top support surface is a curved inclined surface support;

[0022] γ1 represents the angle between the extension of the fixed link and the supporting link when the top support surface is a horizontal plane;

[0023] L2 represents the distance between the fixed point of the fixed link and the fixed point of the adjustable link on the top support surface;

[0024] L3 represents the length of the fixed link;

[0025] L4 represents the length from the extension of the fixed link to the support link;

[0026] L represents the distance from the position of the adjustable link through the support surface to the center of the support surface, which can be calculated according to formula (4).

[0027] Another objective of this invention is to provide a connection method for an adjustable flat and curved surface support frame structure, comprising the following steps:

[0028] Step 1): Place the top support flat on the work platform, dividing it into two symmetrical sides;

[0029] Step 2): The left side of the top support surface is connected to the fixed connecting rod, with a fixed included angle of α. The connection method is a hinge connection, which is connected by a hinge.

[0030] Step 3): The support link is connected to the center of the lower side of the support surface in a rigid connection manner;

[0031] Step 4): Connect the other end of the fixed link to the upper side of the support surface. The connection method is a rigid connection, wherein the extension line of the fixed link through the support surface must be connected to the support link.

[0032] Step 5): After determining the position of the adjustable link, the adjustable link is fixedly connected to the right side of the top support surface and the support link through the scale groove on the support surface.

[0033] This invention provides an adjustable flat and curved surface support frame structure, which consists of a top support surface, a support surface, a fixed connecting rod, a support connecting rod, and an adjustable connecting rod connected in sequence. The bottom support connecting rod is fixed to the node at the top of the full-span support frame. The top support surface is adjusted to a suitable angle so that the top support surface fits tightly with the template. Finally, the position of the adjustable connecting rod is determined and the fixed connection is completed in sequence. At this point, the structure can complete the support of the flat or curved surface, and the force distribution is more scientific and reasonable. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0041] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0042] like Figure 1 and Figure 3 The diagram shown illustrates a structural design of an adjustable flat / curved support frame according to an embodiment of the present invention. The structure includes:

[0043] Top support surface 1, a template used to support the pouring surface;

[0044] Support surface 2, one side of which is connected to top support surface 1 via a fixed connecting rod 3, and the other side of which is connected to top support surface 1 via an adjustable connecting rod 4;

[0045] Support link 5 is connected at the lower center of the support surface 2;

[0046] One end of the fixed connecting rod 3 is hinged to the top support surface 1 via a hinge 6, and the other end of the fixed connecting rod 3 is rigidly connected to the support surface 2.

[0047] In one embodiment of the present invention, the adjustable flat and curved surface support frame structure addresses the problem in the prior art where the outer surface of the construction structure is curved or inclined, and lacks reasonable and scientific support technology for stress design. It is provided with a top support surface 1, a support surface 2, a fixed connecting rod 3, an adjustable connecting rod 4, and a support connecting rod 5, which constitute the entire support system. The surface of the top support surface 1 is used to support the template of the pouring surface. The top support surface 1 and the fixed connecting rod 3 are connected by a hinge. Therefore, the top support surface 1 can rotate up and down around the hinge, so it can be used to support both flat and curved / inclined surfaces.

[0048] like Figure 1 and Figure 3 , Figure 5 As shown, in a preferred embodiment of the present invention, the support surface 2 is provided with a scale groove for determining the position of the adjustable connecting rod 4.

[0049] The graduated groove on the support surface 2 can accurately determine the position of the adjustable link 4. The top support surface 1 and the support surface 2 are connected on one side by a fixed link 3, and the position of the adjustable link 4 is determined by the length or angle of the adjustable link 4 on the other side.

[0050] like Figure 1 and Figure 3 As shown, in another preferred embodiment of the present invention, the adjustable connecting rod 4 fixes the top support surface 1 and the support connecting rod 5 through the scale groove.

[0053] When the top support surface 1 is subjected to force, the resultant force on the fixed connecting rod 3 and the adjustable connecting rod 4 is along the direction of the supporting connecting rod 5. The supporting connecting rod 5 then transmits the resultant force to the node of the full-span scaffold. This force transmission method is scientific and reasonable.

[0054] like Figure 2 and Figure 4 As shown, in a preferred embodiment of the present invention, the position of the adjustable link 4 is calculated using the following formula:

[0055] α + Δα + β + γ = 180° (1)

[0056] sinβ / (L3+L4)=sinγ / L2 (2)

[0057] L / (L4cosγ1)=tan(γ-γ1) (3)

[0058] L=tan{arcsec[sec(α+Δα)-L2 / (L3+L4)sin(α+Δα)]-α-Δα-γ1}L4cosγ1 (4);

[0059] Wherein, Δα represents the change in α when the top support surface 1 changes from horizontal support to curved inclined support;

[0060] β represents the angle between the adjustable connecting rod 4 and the top support surface 1 when the top support surface 1 is a curved inclined surface support;

[0061] γ represents the angle formed by the adjustable connecting rod 4 and the extension line of the support surface 2 when the top support surface 1 is a curved inclined surface support;

[0062] γ1 represents the angle between the extension line of the fixed link 3 and the supporting link 5 when the top support surface 1 is a horizontal support.

[0063] L2 represents the distance between the fixed point of the fixed connecting rod 3 and the fixed point of the adjustable connecting rod 4 on the top support surface 1;

[0064] L3 represents the length of fixed link 3;

[0065] L4 represents the length from the extension of the fixed link 3 to the support link 5;

[0066] L represents the distance from the position of the adjustable link 4 through the support surface 2 to the center of the support surface 2, which can be calculated according to formula (4).

[0067] The position L of the adjustable link 4 on the support surface 2 can be obtained relatively accurately by using the relationship between the interior angles of a triangle and the law of sine.

[0068] A connection method for an adjustable flat and curved surface support frame structure includes the following steps:

[0069] Step 1): Place the top support surface 1 flat on the work platform, dividing it into two symmetrical sides;

[0070] Step 2): The left side of the top support surface 1 is connected to the fixed connecting rod 3, with a fixed included angle of α. The connection method is a hinge connection, which can be connected by hinge 6.

[0071] Step 3): The support rod 5 is connected to the center of the lower side of the support surface 2 in a rigid connection manner;

[0072] Step 4): Connect the other end of the fixed link 3 to the upper side of the support surface 2. The connection method is rigid connection, wherein the extension line of the fixed link 3 through the support surface 2 must be connected to the support link 5.

[0073] Step 5): After determining the position of the adjustable link 4, the adjustable link 4 is fixedly connected to the right side of the top support surface 1 and the support link 5 through the scale groove of the support surface 2. The adjustable link 4 can be finely adjusted and strengthened according to the scale.
