Description
Technical Field
[0001] This utility model belongs to the technical field of construction engineering equipment, specifically relating to a floor splicing frame. Background Technology
[0002] During the construction of the new Chongqing East Railway Station on the Chongqing-Guizhou Railway, the roof adopted a spatial truss structure system, mainly composed of roof truss structures, roof beams, and roof support structures. The main roof truss is a triangular truss with a maximum span of 72m and lower chord support. Some main trusses are connected to the lower tree-shaped columns by pins, while the remaining main trusses are rigidly connected to the lower straight steel columns. For example, [the following is an example]. Figure 1 The schematic diagram of the roof truss structure shown in the image consists of three main truss members and multiple web members welded to them. Due to its large size and weight, it is inconvenient to install and transport. Therefore, it is usually disassembled into multiple segments and transported to the construction site for welding and assembly. During the on-site assembly process, to facilitate fixing and subsequent processing, jigs need to be fabricated on-site to support the disassembled segments on the ground before welding and assembly. This construction method is currently the mainstream solution for the installation of large-volume, heavy-weight building structures, but it also has its drawbacks. There are some shortcomings. The formwork needs to be pre-installed and fixed according to the assembled roof truss segments. After the roof truss segments are hoisted onto the formwork, the two need to be fixedly connected to ensure stability during subsequent construction. After the roof truss is welded, the connection between the formwork and the roof truss needs to be loosened again. The operation is cumbersome, time-consuming and labor-intensive. Usually, a large roof truss requires at least dozens of segments to be welded. Fixing so many roof truss segments to the formwork and then loosening the connection after welding greatly increases the construction cost and efficiency needs to be improved. Utility Model Content
[0003] In view of this, the purpose of this utility model is to provide a floor splicing frame to solve the problem that the current roof truss segments and the frame require construction workers to fix and disassemble them multiple times, resulting in high construction costs and low efficiency.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A floor slab splicing frame includes roof truss segments and a frame assembly fixed to the ground for supporting the roof truss segments. The frame assembly includes multiple support bodies for supporting the roof truss segments and clamping members disposed on each support body for fixing the roof truss segments. Each support body corresponds to a main truss member on the roof truss segment in a vertical plane. Each clamping member is vertically disposed and clamps the corresponding main truss member. Each clamping member includes a bracket fixedly disposed on the upper surface of the corresponding support body and elastically hinged to the bracket. Two clamping blocks are symmetrically arranged on both sides of the corresponding truss main members about the vertical axis of the bracket. An opening is left between the two clamping blocks to allow the truss main members to move. Each clamping block has a pressure surface and a clamping surface that abut against the surface of the truss main member. The clamping surface is higher than the horizontal height of the pressure surface. When the truss main member moves vertically downward toward the opening of the two clamping blocks, the truss main member abuts against the pressure surface of the two clamping blocks and simultaneously drives the clamping blocks to rotate until the clamping surfaces of the two clamping blocks simultaneously abut against the surface of the truss main member and fix it.
[0006] Furthermore, each of the clamping blocks has a groove on the side surface near the main truss member, and multiple sliders that move radially along the main truss member are slidably connected in the groove. Each slider is provided with a first driving member for adjusting the movement of the slider between it and the support block.
[0007] Furthermore, the surface of each slider that abuts against the main truss member is arc-shaped and covered with an anti-slip layer.
[0008] Furthermore, the bottom end of the bracket is connected to a base, and the upper surface of the base is provided with two blocks that are vertically symmetrical about the bracket. Each block corresponds to an adjacent clamping block, and when the opening between the two clamping blocks is opened to the maximum, the surface of the clamping block abuts against the block.
[0009] Furthermore, each of the supporting bodies located on both sides of the roof truss segment is provided with a lead screw for driving the clamping component to move vertically. The lead screw is vertically arranged, and a movable block is sleeved and threadedly connected to the outer surface of the lead screw. The movable block is also slidably connected to the supporting body. The movable block is fixedly connected to the lower surface of the base. The lead screw is connected to a second driving component that drives its movement.
[0010] The beneficial effects of this utility model are as follows:
[0011] 1. This utility model sets up multiple support bodies on the ground to support the main truss pole, and sets clamping parts on the upper surface of each support body. When the main truss pole is hoisted and moves downward in the direction of the opening of the clamping parts, the surface of the main truss pole will drive the two clamping blocks to rotate and abut against its surface through its own weight, realizing the effect of automatic clamping. This effectively reduces the construction steps of construction personnel and the corresponding time costs, and effectively improves work efficiency.

The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

[0022] like Figures 1-6 As shown,
[0023] A floor splicing frame includes a roof truss segment 1 and a frame assembly 2 fixed to the ground for supporting the roof truss segment 1. The roof truss segment 1 consists of three main truss members 101 and multiple web members 102 welded between the main truss members 101 (specific welding steps are detailed in the attached document). Figure 6 As shown), the frame assembly 2 includes three support bodies 201 for supporting the roof truss segment 1 and clamping members disposed on each support body 201 for fixing the roof truss segment 1. Each support body 201 corresponds to a truss main rod 101 on the roof truss segment 1 in the vertical plane. Each clamping member is vertically disposed and clamps the corresponding truss main rod 101. Each clamping member includes a bracket 10 fixedly disposed on the upper surface of the corresponding support body 201 and two clamping blocks 202 elastically hinged to the bracket 10 (the two clamping blocks 202 are provided with torsion springs at the pivot of the bracket 10 and the bracket 10, and normally the two clamping blocks 202 are in an open state). The two clamping blocks 202 are related to the bracket 10. The vertical axis of 0 is symmetrically arranged on both sides of the corresponding truss main rod 101. An opening is left between the two clamping blocks 202 for the truss main rod 101 to move. Each clamping block 202 has a pressure surface and a clamping surface that abut against the surface of the truss main rod 101. The clamping surface is higher than the horizontal height of the pressure surface. When the truss main rod 101 moves vertically downward toward the opening of the two clamping blocks 202, the truss main rod 101 abuts against the pressure surface of the two clamping blocks 202 and simultaneously drives the clamping blocks 202 to rotate until the clamping surfaces of the two clamping blocks 202 simultaneously abut against the surface of the truss main rod 101 and fix it. Each roof truss segment 1 is supported and fixed at both ends by at least two frame assemblies 2.
[0024] As shown in the figure, this roof truss segment 1 is supported by at least two jig assemblies 2 arranged along its length. Before assembling the roof truss segment 1, three main truss members 101 need to be placed horizontally on the jigs and clamped and fixed by clamping components. Each main truss member 101 is horizontally positioned during hoisting and moves vertically toward the openings of the two clamping blocks 202. When the main truss member 101 enters the inner side of the two clamping blocks 202 and simultaneously abuts against the pressure surface, the two clamping blocks 202 rotate under the weight of the main truss member 101 and move closer to each other until the two clamping surfaces simultaneously abut against the surface of the main truss member 101. Since the main truss member 101 is made of steel, its own weight will... This design ensures that the two clamping blocks 202 are firmly pressed against their surfaces, achieving an automatic clamping effect. This effectively reduces the need for manual operation and fixing of the truss main rod 101 by construction personnel, thus reducing their costs and burden. Furthermore, when it is necessary to remove the truss main rod 101, it is only necessary to hoist the truss main rod 101 again and move it vertically upward. Since the weight of the truss main rod 101 is borne by the hoisting device, no pressure is applied to the pressure surfaces of the two clamping blocks 202. Therefore, under the action of the torsion spring, the two clamping blocks 202 will move away from each other and reset, and the clamping surfaces will no longer press against the truss main rod 101. The truss main rod 101 can be easily removed, reducing the need for construction personnel to untie the fixing steps of the truss main rod 101 and effectively improving construction efficiency.
[0025] In this embodiment, each clamping block 202 has a groove on its surface near the truss main rod 101, and two sliders 3 that move radially along the truss main rod 101 are slidably connected in the groove. Each slider 3 is provided with a first driving member 4 for adjusting the movement of the slider 3 between it and the support block. As shown in the figure, the first driving member 4 consists of a rotating rod rotatably disposed on the surface of the slider 3 and a rotating block fixedly connected to the free end of the rotating rod. The rotating rod is arranged radially along the clamped truss main rod 101, and the end of the rotating rod away from the slider 3 extends out of the clamping block. The block 202 is fixedly connected to the rotating block, and the rotating rod is also threadedly connected to the clamping block 202; the side surface of each slider 3 that abuts against the truss main rod 101 is arc-shaped and covered with an anti-slip layer; the bottom end of the bracket 10 is welded and fixed with a base 5, and the upper surface of the base 5 is provided with two vertically symmetrical blocks 6 about the bracket 10. Each block 6 corresponds to the adjacent clamping block 202, and when the opening between the two clamping blocks 202 is opened to the maximum, the block 6 abuts against the surface of the clamping block 202 and restricts the movement of the clamping block 202.
[0026] As shown in the figure, when the truss main rod 101 is clamped and fixed for the first time by the corresponding clamping device, by turning the rotating block and driving the rotating rod to rotate, the rotating rod will drive the corresponding slider 3 to move radially along the truss main rod 101, so that one side surface of the slider 3 abuts against the surface of the truss main rod 101. The sliders 3 on other clamping blocks also adhere tightly to the truss main rod 101 through the above operation steps. The anti-slip layer can effectively improve the friction coefficient between the slider 3 and the truss main rod 101 (and also reduce the scratches on the surface of the truss main rod 101 by the slider 3), which can further improve the stability and clamping force when the truss main rod 101 is clamped and fixed. Of course, each slider 3 only needs to be adjusted once, and then the same size truss main rod 101 can be effectively clamped and fixed. Furthermore, when it is necessary to fix truss main rods 101 with different radii, the slider 3 can also be moved by adjusting the rotating block, and the clamping effect of truss main rods 101 with different sizes within a certain range can be achieved, which improves the applicability of this clamping device.
[0027] Furthermore, after the truss main rod 101 disengages from the clamping member, the two clamping blocks 202 move away from each other under the action of the torsion spring until the surface of the clamping block 202 abuts against the stop block 6. At this time, the opening angle between the two clamping blocks 202 is at its maximum, which facilitates the truss main rod 101 to re-enter the clamping member. The stop block 6 can effectively prevent the opening of the two clamping blocks 202 from being too large, ensuring the stability of its movement.
[0028] In this embodiment, each of the support bodies 201 located on both sides of the roof truss segment 1 is provided with a lead screw 7 for driving the clamping member to move vertically. The lead screw 7 is vertically arranged, and a movable block 8 is sleeved and threadedly connected to the outer surface of the lead screw 7. The movable block 8 is also slidably connected to the support body 201. The movable block 8 is fixedly connected to the lower surface of the base 5 by bolts. The lead screw 7 is connected to a second driving member 9 that drives its movement. The second driving member 9 includes a turntable and a bevel gear set. The turntable is rotatably arranged on the surface of the corresponding support body 201, and the turntable and the lead screw 7 are poweredly connected through the bevel gear set.
[0029] As shown in the figure, since the three truss main rods 101 are arranged in a triangular structure, only two of the truss main rods 101 need to be adjusted in height, while the height of the other truss main rod 101 remains unchanged, to achieve different combination effects. Therefore, in this embodiment, only two support bodies 201 are equipped with lead screws 7 and second driving components 9 for adjusting the height of the truss main rods 101, while the height of the other support body 201 remains unchanged. Through the cooperation of the turntable and the bevel gear set, the lead screw 7 can be driven to rotate. While the lead screw 7 rotates, it drives the movable block 8 to move up and down, thereby achieving the effect of adjusting the height of the clamping component and the truss main rod 101, and fixing and assembling roof truss segments 1 with different arrangement shapes, which can further improve the applicability of this utility model.
[0030] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
