Description

Technical Field

[0001] This utility model relates to the field of support device technology, and in particular to a fixed wooden truss support device for concrete pouring in flow channels. Background Technology

[0002] A timber truss is a truss composed of wooden components. When pouring concrete into flow channels, formwork is needed to shape the channels. The timber truss serves as part of the formwork support system. It can bear the weight of the formwork and concrete, preventing the formwork from deforming or collapsing during concrete pouring.

[0003] Wood is affected by environmental factors during use, such as humidity changes. When wood absorbs or releases moisture, it expands or contracts. At the joints of a wooden truss, such dimensional changes may cause the joints to loosen. For example, in a humid environment, wood absorbs moisture and expands; when the environment becomes dry, the wood shrinks, creating gaps and loosening at the joints, affecting the stability of the entire wooden truss. Therefore, this application proposes a shaped wooden truss support device for concrete pouring in flow channels. Utility Model Content

[0004] The purpose of this invention is to address the problem in the prior art where the connection of wooden trusses can easily affect stability, and to propose a fixed wooden truss support device for concrete pouring in flow channels.

[0005] The technical solution of this utility model is as follows: A fixed wooden truss support device for concrete pouring in a flow channel includes a lower chord and connecting blocks. The connecting blocks are symmetrically fixedly installed on both sides of the lower chord. A fixing plate is fixedly installed on the connecting blocks, and a side chord is fixedly installed on the fixing plate. An upper chord is fixedly installed on one side of the side chord. A middle web member is fixedly installed at the center of the lower chord. Vertical web members are symmetrically fixedly installed on both sides of the lower chord. One end of the vertical web member is fixedly connected to the side chord. A limiting mechanism to enhance the stability of the side chord is provided on the lower chord.

[0006] Optionally, the limiting mechanism includes reinforcing rods that are fixedly and symmetrically installed on both sides of the lower chord, with the other end of the reinforcing rod bolted to the middle web member, and both sides of the reinforcing rod bolted to the vertical web member. Limiting rods are symmetrically and fixedly installed on the middle web member, with one end of the limiting rod bolted to the vertical web member and the other end of the limiting rod fitting against the reinforcing rod.

[0007] Optionally, an upper chord is fixedly installed on the middle web member, and one end of the upper chord is bolted to the side chord.

[0008] Optionally, the connecting block is provided with a first connecting groove, which is sleeved on both ends of the lower chord.

[0009] Optionally, the fixing plate is provided with a second connecting groove, which is fixedly connected to the side chord.

[0010] Optionally, the reinforcing rod is located below the side chord, and the side chord and the reinforcing rod are arranged parallel to each other.

[0011] Optionally, one end of the side chord is fixedly connected to the middle web member, and one end of the side chord abuts against both sides of the upper chord.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] This invention improves the stability of the entire wooden truss by setting up a triangle between the side chord and the bottom chord. In conjunction with the connecting blocks on both sides of the bottom of the bottom chord, it enhances the stability of the connection point between the side chord and the bottom chord, reduces weak points caused by the connection between the two, and increases the ease of installation.

[0014] Furthermore, by setting the reinforcing rod parallel to the side chord and bolting it to the vertical and middle web members, the stability of the connection between the side chord, middle web member, and vertical web member is further improved. In conjunction with the limit rod bolting it to the vertical and middle web members, the fixation between the fixing rod and the lower chord and middle web member is improved.

[0015] This invention improves the stability of the entire wooden truss and its connections, facilitates installation and dismantling, has high installation precision, and is highly practical. Attached Figure Description

A fixing plate 6 is fixedly installed on the connecting block 3, and a side chord 10 is fixedly installed on the fixing plate 6. This improves the stability of the connection between the lower chord 1 and the side chord 10, reduces the weak points caused by the connection between the two, and makes the installation more convenient and efficient. The side chord 10 is bolted to the fixing plate 6. An upper chord 8 is fixedly installed on one side of the side chord 10. A middle web member 2 is fixedly installed at the center of the lower chord 1. The bottom of the lower chord 1 is bolted to the bottom of the middle web member 2. Vertical web members 4 are symmetrically fixedly installed on both sides of the lower chord 1. One end of the vertical web member 4 is fixedly connected to the side chord 10. A limiting mechanism to enhance the stability of the side chord 10 is provided on the lower chord 1.

[0029] like Figure 2-3 As shown, the limiting mechanism includes reinforcing rods 5 fixedly and symmetrically installed on both sides of the lower chord 1. The other end of the reinforcing rod 5 is bolted to the middle web rod 2. Both sides of the reinforcing rod 5 are bolted to the vertical web rod 4, so that it can provide support for the upper middle part of the middle web rod 2. Limiting rods 11 are symmetrically and fixedly installed on the middle web rod 2. One end of the limiting rod 11 is bolted to the vertical web rod 4. The limiting rod 11 connects the reinforcing rod 5 and the middle web rod 2, improves the fixing effect, and makes the overall structure more stable. One end of the limiting rod 11 fits against the reinforcing rod 5.

[0030] like Figure 3-4 As shown, an upper chord 8 is fixedly installed on the middle chord 2. The upper chord 8 is bolted to one end of the side chord 10 to connect the side chords 10 on both sides.

The lower chord 1 is bolted to the first connecting groove 9 so that it can be installed quickly. A second connecting groove 7 is provided on the fixing plate 6. The second connecting groove 7 is fixedly connected to the side chord 10. The second connecting groove 7 is threadedly connected to the side chord 10. The reinforcing rod 5 is located below the side chord 10. The side chord 10 and the reinforcing rod 5 are arranged in parallel. One end of the side chord 10 is fixedly connected to the middle chord 2. One end of the side chord 10 abuts against both sides of the upper chord 8.

[0031] The working principle of this embodiment is as follows: the triangular arrangement formed by the side chord 10 and the lower chord 1 improves the stability of the entire wooden truss. The connecting blocks 3 on both sides of the lower chord 1 make the connection point between it and the side chord 10 more stable and easier to install. The parallel arrangement of the reinforcing rod 5 with the side chord 10 and its bolted connection with the vertical web member 4 and the middle web member 2 further improves the stability of the connection between the side chord 10, the middle web member 2, and the vertical web member 4. The bolted connection of the limiting rod 11 with the vertical web member 4 and the middle web member 2 improves the fixation between the reinforcing rod 5, the lower chord 1, and the middle web member 2. This achieves improved stability of the entire wooden truss and its connections, convenient installation and dismantling, high installation accuracy, and strong practicality.
