The overall hoisting method has high requirements for the hoisting environment, and the quality is difficult to control during the overall hoisting process. At the same time, ground assembly will occupy too much space, and the production cost will be high. Utility Model Content

[0007] The construction platform is located on the upper surface of the roof. The sliding mechanism is symmetrically located on the outer top wall of a set of parapet walls opposite each other along the length of the roof. One end of the support mechanism is connected to the end of the truss, and the other end is connected to the sliding mechanism. The support mechanism can slide along the extension direction of the sliding mechanism to drive the truss to move synchronously.

[0019] This utility model provides a roof truss sliding construction fixture, including a sliding mechanism, a support mechanism, and a construction platform. The construction platform is directly set on the upper surface of the roof to facilitate welding and assembly operations by construction personnel. Simultaneously, sliding mechanisms are symmetrically arranged on the outer top walls of a set of parapet walls opposite each other along the length of the roof. One end of the support mechanism is connected to the end of the truss, and the other end is connected to the sliding mechanism.

[0031] like Figure 1 and Figure 2As shown, this utility model provides a roof truss sliding construction fixture, including a sliding mechanism, a support mechanism, and a construction platform 100. The construction platform 100 is located on the upper surface of the roof 200. The sliding mechanism is symmetrically located on the outer top wall of a set of parapet walls 201 opposite each other along the length direction of the roof 200. One end of the support mechanism is connected to the end of the truss 202, and the other end is connected to the sliding mechanism. The support mechanism can slide along the extension direction of the sliding mechanism to drive the truss 202 to move synchronously.

[0032] In this embodiment, the roof truss sliding construction fixture includes a sliding mechanism, a support mechanism, and a construction platform 100. The construction platform 100 is directly installed on the upper surface of the roof 200 to facilitate welding and assembly operations by construction personnel. Simultaneously, sliding mechanisms are symmetrically arranged on the outer top walls of a set of parapet walls 201 opposite each other along the length of the roof 200. One end of the support mechanism is connected to the end of the truss 202, and the other end is connected to the sliding mechanism. Since the support mechanism can slide along the extension direction of the sliding mechanism, it can drive the truss 202 to move synchronously, so that it can be transported to the designated position for construction personnel to carry out construction. This avoids the high costs incurred by using special hoisting equipment when assembling on the ground first and then hoisting the whole structure. Only ordinary tower cranes are needed to complete the hoisting. At the same time, displacement measurement can be carried out in real time during the sliding process, which can better control the installation quality of the truss 202.

[0033] According to one embodiment provided by this utility model, such as Figure 1 and Figure 2 As shown, the sliding mechanism includes two slide rails 300, which are symmetrically arranged on the outer top wall of a set of parapet walls 201 opposite each other along the length of the roof 200.

[0034] In this embodiment, the sliding mechanism includes two slide rails 300. Preferably, the two slide rails 300 are arranged symmetrically, that is, the two slide rails 300 are arranged parallel to each other on the outer top wall of a set of parapet walls 201 opposite to each other along the length direction of the roof 200, so as to ensure that the displacement at both ends of the truss 202 can be kept consistent.

[0037] Preferably, the sliding traction of the support column 400 is accomplished by using an electric hoist. The support columns 400, which are symmetrically arranged on two slide rails 300, are simultaneously pulled by an electric hoist to achieve the effect of uniform force on both sides of the truss 202, while also saving costs and speeding up the construction period.

[0038] According to one embodiment provided by this utility model, such as Figure 2 As shown, the support mechanism also includes a reinforcing column 401, one end of which is connected to the support column 400, and the other end is connected to the truss 202.

The gasket is in contact with the bottom wall of the support column 400, and the side of the gasket facing the support column 400 is coated with a drag-reducing layer.

[0041] In this embodiment, each slide rail 300 is provided with a shim inside. Preferably, the shim is made of stainless steel plate. The shim is attached to the bottom wall of the support column 400, and a friction-reducing layer is coated on the side of the shim facing the support column 400 to reduce the frictional resistance between the support column 400 and the slide rail 300, that is, to reduce the coefficient of friction, thereby effectively reducing the difficulty of sliding and improving construction efficiency.

[0042] Optionally, the drag-reducing layer can be formed by coating the upper surface of the pad with grease, which is low in cost and has a significant effect on reducing the difficulty of sliding.

[0043] According to one embodiment provided by this utility model, such as Figure 1 As shown, the construction platform 100 includes a platform 101 and a column 102. One end of the column 102 is vertically installed on the roof 200, and the platform 101 is connected to the other end of the column 102 away from the roof 200.

One end of each column 102 is perpendicular to the plane of the roof 200. The platform 101 is fixed to the other end of the column 102 away from the roof 200, thereby providing a construction platform 100 for construction workers to carry out construction work and ensure construction efficiency and quality.

[0047] According to one embodiment provided by this utility model, such as Figure 1 As shown, the top surface of the countertop 101 is flush with the top surface of the parapet wall 201.

[0048] In this embodiment, in order to facilitate construction personnel to observe the displacement distance of the column 102 inside the slide rail 300 at all times and to make it convenient to measure, the top surface of the platform 101 is flush with the top surface of the parapet wall 201.

After the truss 202 is fully assembled, a jack is used for support, the column 102 and the slide rail 300 are removed, and then the first connecting piece 402 and the second connecting piece are welded together to fix them, thereby achieving the effect of fixing the roof 200 to the truss 202 and completing the installation of the truss 202 of the roof 200.

[0051] According to one embodiment provided by this utility model, such as Figure 2 As shown, the slide rail 300 is provided with mounting holes, and the fastener 301 passes through the mounting holes and the parapet wall 201 in sequence.

[0052] In this embodiment, preferably, the slide rail 300 is made of channel steel.
