[0003] However, the existing dustproof canopy brackets are fixed by pre-embedded or other non-detachable fixing methods, which has low construction efficiency, and the brackets cannot be freely moved and cannot be used cyclically after construction, which is costly.

[0004] Based on this, it is necessary to study a movable dust-proof canopy support device. Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide a movable dustproof canopy support device, which can effectively solve the problem that the existing dustproof canopy bracket cannot be moved and cannot be circulated after being built.

A column is vertically installed on the horizontal support. The column is combined with an inclined support rod to form a single stable support point. A top beam is erected on the top of each column. Each horizontal support is fixedly connected by a ground beam to form a single-sided support as a whole. It is symmetrically arranged in two groups, and a steel wire rope is connected between the top beams between the two groups, thereby forming a complete dustproof canopy support foundation. Compared with the traditional dustproof canopy support structure, it does not require embedded bolts and cast foundations, and is quick to deploy. After use, the top beam and the ground beam can be disassembled, and the counterweight can be released to quickly dismantle the device for storage, so that it can be used in rotation.

It can be used in rotation for many times, reducing construction costs.

[0020] (2) The utility model adopts diagonal braces and ground beams to achieve the reliability of the supporting structure. The diagonal braces are fixedly connected with the columns and the horizontal base to form a triangular structure, which significantly enhances the lateral stability of the entire device and prevents swaying or tipping caused by lateral forces (such as wind pressure); the ground beam connects the various horizontal supports into a whole to ensure the integrity and rigidity of the structure in the longitudinal direction; in addition, the counterweight frame is arranged at the connection point between the ground beam and the horizontal support to increase the bottom weight of the entire structure, while the diagonal braces and the counterweight frame are respectively located on the left and right sides of the columns to form a symmetrical supporting structure and provide two-way stable support. This layout helps to evenly distribute the loads introduced from the canopy and external conditions (such as wind pressure), reduce the tilting or collapse that may be caused by overload on one side, and improve the stability and reliability of the overall structure.

DETAILED DESCRIPTION

[0030] The utility model is further described in detail below with reference to the accompanying drawings and specific implementation methods:

[0031] Embodiment 1, this embodiment aims to provide a movable dustproof canopy support device, which is mainly used for deploying dustproof canopy during foundation pit construction, and aims to solve the problem that the bracket of the existing dustproof canopy cannot be moved and cannot be circulated after being erected.

[0032] A movable dustproof canopy support device, such as Figure 1 and Figure 3 , including a horizontal support 1, a column 2, a diagonal brace 3, a counterweight frame 4, a top beam 5, a steel wire rope 6 and a ground beam 7; the horizontal support 1 is an H-shaped steel beam, and the horizontal support 1 is horizontally arranged on the ground along the left and right directions, wherein the left and right directions refer to Figure 3 .like Figure 3 , the column 2 is an H-shaped steel beam, and the column 2 is vertically installed in the middle of the horizontal support 1, such as Figure 4 The web of the column 2 is bolted to the upper edge plate of the horizontal support 1 through an L-shaped connecting plate 8.

[0033] The diagonal brace 3 is arranged obliquely, the top end of the diagonal brace 3 is fixedly connected to the column 2, and the bottom end of the diagonal brace 3 is fixedly installed on the horizontal support 1; a hinge seat 9 is installed on the upper part of the column 2, and a round hole is opened on the top end of the diagonal brace 3 and is hingedly connected to the column 2 through a rotating shaft and the hinge seat 9; Figure 6 A horizontal mounting plate 10 is welded and fixed to the bottom of the diagonal brace 3, and is bolted to the upper edge plate of the horizontal support 1 through the mounting plate 10. The upper end of the diagonal brace 3 is hinged and the lower end is fixed, so that when assembling and disassembling, the lower end can be removed and the upper end can be folded and stored, simplifying the installation steps.

[0034] like Figure 2 , the horizontal support 1, the column 2, the diagonal support rod 3 and the counterweight frame 4 are arranged in multiple groups at intervals along the front-to-back direction, and the top of each column 2 is detachably connected with a top beam 5, such as Figure 5 , the top beam 5 is an H-shaped steel beam, and the top beam 5 is bolted to the column 2 through an L-shaped connecting plate 8; each horizontal support 1 is vertically and detachably connected with a ground beam 7 along the front-to-back direction, and the ground beam 7 is located on the side opposite to the diagonal support rod 3. The counterweight frame 4 is bolted to the horizontal support 1 and at the connection point between the ground beam 7 and the horizontal support 1. Sand or sandbags are placed in the counterweight frame 4 to increase the weight of the horizontal support 1 and transfer the center of gravity to the connection node between the ground beam 7 and the horizontal support 1, providing a good fixed foundation and increasing stability. The ground beam 7 is an H-shaped steel beam, and can also be square steel, etc. It is mainly used to connect the horizontal supports 1 arranged at intervals in the front and back into a whole to improve the overall stability. The ground beam 7 is a full-length steel beam, and the model size is smaller than the horizontal support 1, so that the ground beam 7 is connected from the web position of the horizontal support 1 to achieve a quick installation effect. The structure is simple and reliable, and it is suitable for the situation where the ground is flat and continuous.

[0035] like Figure 1 and Figure 2The horizontal support 1, the column 2, the diagonal brace 3, the counterweight frame 4 and the top beam 5 are arranged symmetrically in two rows. The top beam 5 is provided with a through hole for tying and fixing the steel wire rope 6, wherein the left and right groups of top beams 5 are vertically connected with the steel wire rope 6 through the through hole, and the steel wire rope 6 is arranged at intervals along the front and rear direction. The steel wire rope 6 is mainly used to install the dustproof canopy. Regarding the installation of the dustproof canopy, it is an existing technology in this field to install and deploy the dustproof canopy by using the top beams 5 on both sides and the steel wire rope 6 connecting the top beams 5 on both sides. The dustproof canopy can be directly fixed and tied to the steel wire rope 6 and the top beams 5 on both sides, which will not be repeated here.

[0036] In order to further optimize the mechanical properties and stability of the structure, such as Figure 1 The diagonal bracing rod 3 is arranged on the opposite side of the left and right columns of horizontal supports 1, while the counterweight frame 4 and the ground beam 7 are arranged on the opposite side of the left and right columns of horizontal supports 1.

[0037] Embodiment 2: This embodiment is basically the same as Embodiment 1, except that the connection node between the ground beam 7 and the horizontal support 1 is improved. This embodiment further illustrates the structure.

[0038] Considering that the bottom of the ground beam 7 in Example 1 is not in direct contact with the ground but has a gap, it cannot increase the contact area of ​​the overall structure with the ground, cannot effectively deal with the situation of ground subsidence, and has a high requirement for the flatness of the ground. When facing an uneven ground, the installation of the ground beam 7 is more difficult, and when the length of the ground beam 7 is long, it is inconvenient to transport; in this embodiment, if Figure 6 and Figure 7 The ground beam 7 is segmented, with a ground beam 7 connected between every two horizontal supports 1, and the horizontal support 1 and the ground beam 7 are bolted to the counterweight frame 4 to form a whole; the ground beam 7 and the horizontal support 1 are still H-shaped steel beams, and the model of the ground beam 7 is still smaller than that of the horizontal support 1, so that the upper and lower thicknesses of the ground beam 7 are smaller than the upper and lower thicknesses of the horizontal support 1, and the upper surface of the horizontal support 1 contacts the bottom of the counterweight frame 4, so that an adjustment gap is formed between the ground beam 7 and the counterweight frame 4, and the adjustment gap is filled with pads 11. By replacing pads 11 of different thicknesses, the ground beam 7 can be appropriately adjusted up and down to adapt to the uneven ground conditions, and the lower surface of the ground beam 7 can be in contact with the ground as much as possible, thereby increasing the contact area of ​​the structure with the ground and preventing sinking.

[0039] In order to further improve the connection strength between the ground beam 7 and the horizontal support 1, a reinforcement piece 12 is also included. The reinforcement piece 12 is L-shaped and has an upward and downward adjustment flat hole 13 on the reinforcement piece 12; the reinforcement piece 12 is fixedly connected to the horizontal support 1 and is bolted to the ground beam 7 through the adjustment flat hole 13 to adapt to the upward and downward adjustment ability of the ground beam 7.
