Description

Temporary structures to prevent construction equipment from falling

The present invention is composed of a support frame installed on the upper surface of the ground at the border of the work site and a pair of supports that protrude from the front of the support frame and on which the wheels of construction equipment are seated, making installation and disassembly easy, and depending on the size of the construction equipment. This is a temporary structure to prevent construction equipment from tipping over, which can be operated variably depending on the load and can safely prevent construction equipment from tipping over without digging into the ground.

In construction or civil engineering work, drilling equipment such as piles for foundation construction or cranes for transporting materials are used.

Drilling equipment reaches a height of 20 to 40 m, and the equipment itself has a dead weight of 80 to 130 tons. In addition, mobile cranes also have a self-weight of several tens of tons, and the maximum working height is quite high, ranging from 40 to 90 m.

Construction equipment such as drilling equipment and cranes are high in height, so falling accidents often occur during construction.

In particular, when construction is carried out with large construction equipment on a site adjacent to a railroad facility, subway facility, or other important facility, extensive damage may occur if the construction equipment tips over to the adjacent major facility.

Therefore, a temporary structure to prevent tipping over is installed at the border of the work site where construction is taking place to prevent large construction equipment from tipping over to adjacent major facilities.

The conventional fall prevention temporary structure 100 shown in FIG. 1 is configured in a lattice form by installing posts 101, which are shape steel members, spaced apart in the horizontal direction, and installing horizontal support beams 102 in the horizontal direction on the posts 101. do.

When the construction equipment (1) falls, the post (101) is built into the ground at a certain depth in order to support the load of the construction equipment (1) by the bending rigidity of the post (101).

However, the conventional fall-prevention temporary structure in the form of this fence installs a plurality of posts into the ground, and after installing the posts, a horizontal support beam must be connected to the posts. Therefore, it takes a lot of installation time and constructability is poor.

In addition, when removing or moving a temporary structure to prevent falls, the horizontal support beam must be dismantled and the post pulled out. Therefore, it also takes a lot of time, and there is a problem that separate large-scale construction equipment must be used again to pull out the post.

In addition, since the conventional fall-prevention temporary structure has posts embedded in the ground and fixed, it is very cumbersome to move or relocate it depending on site conditions. In addition, it is difficult to freely adjust the height depending on the size of the construction equipment.

In order to solve the above problems, the present invention seeks to provide a temporary structure to prevent construction equipment from falling over, which is very easy to install and dismantle, and can be operated variably depending on the size or load of the construction equipment.

Hereinafter, the present invention will be described in detail according to the accompanying drawings and preferred embodiments.

Figure 2 is a perspective view showing a temporary structure to prevent construction equipment from falling according to the present invention. Figure 3 is a perspective view showing a state in which construction equipment is mounted on a temporary structure to prevent construction equipment from tipping over, and Figure 4 is a diagram showing the concept of preventing construction equipment from tipping over by a temporary structure to prevent construction equipment from tipping over.

As shown in Figures 2 to 4, etc., the construction equipment fall prevention temporary structure of the present invention is intended to prevent the construction equipment (1) from falling, and is used to support the construction equipment (1) when the construction equipment (1) falls. A support frame (3) installed on the upper surface of the ground at the boundary of the work site; and a pair of supports (4) that protrude forward from the front of the support frame (3) on which the wheels of the construction equipment (1) are seated and are spaced apart from each other in the transverse direction. It is characterized by being composed of.

The present invention is very easy to install and dismantle, can be operated variably depending on the size or load of the construction equipment (1), and can safely prevent the construction equipment (1) from falling without entering the ground. It is intended to provide a temporary structure.

The construction equipment fall prevention temporary structure (2) of the present invention prevents the construction equipment (1) from falling toward the existing main facility when construction is carried out with high-height construction equipment (1) adjacent to the existing main facility. Protect existing major facilities.

The fall prevention temporary structure (2) consists of a support frame (3) and a support portion (4).

The support frame 3 is installed at the border of the work site adjacent to the main facility.

Unlike conventional fall-prevention temporary structures installed in the ground, the support frame 3 is simply mounted on the upper surface of the ground at the boundary of the work space.

The support frame (3) has a predetermined height, and is at least 1/3 to 1/2 the height of the construction equipment (1) to support the construction equipment (1) and prevent the construction equipment (1) from falling. It is desirable to have.

The support frame (3) is self-supporting, lightweight, and can be configured in the form of a rectangular parallelepiped formed by vertically and horizontally assembled section steel materials to effectively prevent the construction equipment (1) from falling.

A pair of the support portions 4 are formed to protrude from the front of the support frame 3.

That is, the support frame 3 is provided in a vertical direction, and the support portion 4 is provided in a horizontal direction, forming right angles to each other.

At this time, the rear of the support portion 4 may be rigidly connected to the support frame 3 to resist rotation.

A pair of support portions 4 are provided to be spaced apart from each other on the left and right.

Construction equipment (1) rides on the upper surface of the support portion (4). That is, the wheels on both sides of the construction equipment (1) are each seated on the upper surface of the pair of supports (4).

Accordingly, the temporary structure (2) is prevented from falling due to the self-weight of the construction equipment (1).

That is, even if the construction equipment (1) is tilted and the front (e.g., front leader part) of the construction equipment (1) presses the top of the support frame (3), the center of gravity of the construction equipment (1) is the construction equipment (1) ), so the construction equipment (1) presses the support portion (4) downward to prevent it from falling (Figure 4).

The front end of the support portion 4 may be provided with an entry slope portion 41 whose height decreases toward the front to facilitate movement of the construction equipment 1 into the upper part of the support portion 4.

The support portion 4 can be constructed by connecting a plurality of H-beams with excellent cross-sectional performance laterally.

The position of the support portion 4 can be changed depending on the wheel width of the construction equipment 1 mounted on the top.

Existing temporary structures to prevent falls were constructed with posts embedded in the ground, so it was difficult to move the temporary structures to prevent falls in reality. Accordingly, it was necessary to install temporary structures to prevent falls along the entire construction site boundary on the main facility side. In contrast, in the present invention, since the fall prevention temporary structure (2) is easy to move, it may be installed only at the construction location of the construction equipment (1).

Since the fall prevention temporary structure 2 is simply installed on the upper surface of the ground, it is easy to install, change the location, or dismantle.

When the construction equipment (1) is a drilling equipment, ground drilling work is performed through the space between the mutually spaced support parts (4) while the construction equipment (1) is mounted on the upper part of a pair of support parts (4). possible.

As shown in FIG. 2, etc., an inclined reinforcement bar (5) may be coupled between the support portion (4) and the support frame (3).

After installing the fall prevention temporary structure (2) in the correct position, construction equipment (1) is entered through the front of the support part (4) and moved to the upper part of the support part (4). Therefore, the support portion 4 must be formed to be somewhat thin.

In this case, if the support portion 4 is directly joined to the support frame 3 in a cantilever structure, there is a limit to the bending rigidity of the joint between the support portion 4 and the support frame 3.

Therefore, by installing an inclined reinforcement bar (5) between the support part (4) and the support frame (3), the bending rigidity of the right corner where the support part (4) and the support frame (3) are joined can be reinforced.

The upper end of the inclined reinforcement (5) may be hinged to the front of the support frame (3), and the lower end may be hinged to the upper surface of the support unit (4).

The upper and lower ends of the inclined reinforcement (5) can be detachably coupled to the support frame (3) and the support portion (4), respectively.

It is desirable that the position where the inclined reinforcement (5) is coupled to the support portion (4) is set to a location that does not interfere with the wheels of the construction equipment (1) mounted on the top of the support portion (4).

As shown in FIG. 3, etc., fixed spikes 6 that are embedded and supported in the lower ground may be formed to protrude from the lower surface of the support portion 4.

When construction equipment 1 enters the upper part of the support 4 or the construction equipment 1 is about to fall, the position of the fall prevention temporary structure 2 may be pushed off the ground.

Therefore, a plurality of fixed spikes 6 can be formed to protrude from the lower surface of the support portion 4 so that the fall-prevention temporary structure 2 can firmly maintain its correct position without being pushed against lateral force.

The fixed spike (6) can be installed on the support portion (4) so that it penetrates the support portion (4) through the upper part of the support portion (4) and protrudes to the lower part of the support portion (4).

When the support portion 4 is made of H-beam steel, fixed spikes 6 can be installed through the upper and lower flanges of the H-beam steel.

The fixed spike (6) can be fixed to the flange with a nut. If necessary, the fixing spike 6 can be removed from the support part 4 by loosening the nut or lifted upward to release its fixation to the ground.

Figure 5 is a perspective view showing a unit frame. And Figure 6 is a perspective view showing the coupling relationship of unit frames adjacent to the left and right, and Figure 7 is a perspective view showing the coupling state of unit frames adjacent to the left and right.

As shown in FIG. 5, the support frame 3 can be formed by combining a plurality of unit frames 30, in which a plurality of horizontal bars 31 and a vertical bar 32 are formed of a rectangular parallelepiped, vertically, horizontally, and horizontally. .

Construction equipment (1) varies in width and height depending on the type of equipment and specifications.

Therefore, in order to easily adapt to the size of the construction equipment 1 and improve lifting and transportation convenience, the support frame 3 can be divided into small unit frames 30.

That is, the support frame 3 can be formed by assembling a plurality of unit frames 30 of the same standard up and down and/or left and right.

The unit frame 30 consists of four lower horizontal bars 31, four upper horizontal bars 31, and four vertical bars 32 connecting the ends of the upper and lower horizontal bars 31, and has an overall rectangular parallelepiped shape. can be formed.

In order to reinforce the rigidity of the unit frame 30, a bracing material 33 may be provided on each side of the unit frame 30 to connect neighboring corners.

As shown in FIGS. 5 to 7, coupling plates 34 may be provided at both ends of the horizontal bar 31.

The coupling plate 34 is provided to protrude outward from one end of the horizontal bar 31, and may be coupled to the inside of the horizontal bar 31 at the other end of the horizontal bar 31.

A fastening hole (H) may be formed through the coupling plate 34.

When the coupling plate 34 is coupled to the inside of the horizontal bar 31, a fastening hole H may be formed in the web of the horizontal bar 31.

Neighboring unit frames 30 can be joined by fastening the fastening members 7 to simultaneously penetrate the plurality of fastening holes H with the coupling plates 34 of the horizontal bars 31 on both sides overlapped (see Figure 6, Fig. 7).

When the support frame 3 is divided into small unit frames 30, lifting and transportation is possible even with small equipment.

FIG. 8 is an enlarged view showing part A of FIG. 2.

As shown in FIGS. 2 and 8, a fastening hole (H) penetrating upward and downward is formed in the horizontal bar 31 of the unit frame 30, so that the unit frames 30 stacked vertically are adjacent to each other vertically. They can be joined to each other by fastening the fastening member (7) to the fastening hole (H) of the horizontal bar (31).

In order to join the unit frames 30 stacked vertically to each other, fastening holes H may be formed through the horizontal bar 31 vertically.

Accordingly, after stacking the unit frames 30 up and down, fastening members 7 such as bolts can be fastened to the fastening holes H of the horizontal bars 31 to be joined to each other.

The overturning load of construction equipment (1) acts only in the front-to-back direction of the support frame (3). Therefore, a fastening hole (H) may be formed in the front and rear horizontal bars 31 of the unit frame 30 to which the fastening member 7 is fastened.

When the horizontal bar 31 is an H-beam steel, fastening holes H may be formed in the upper and lower flanges of the H-beam steel.

When the inclined reinforcement (5) is provided, the upper end of the inclined reinforcement (5) is the horizontal bar (31). It can be fixed to the fastening hole (H) with a fastening member (7) such as a bolt.

Figure 9 is a bottom perspective view showing the coupling relationship between the support and the unit frame, and Figure 10 is an enlarged view showing part B of Figure 9.

As shown in FIGS. 9 and 10, the support portion 4 may be fixed to the front and rear horizontal bars 31 of the unit frame 30, the rear of which is disposed at the bottom, respectively.

When the inclined reinforcement (5) is installed between the support (4) and the lowest unit frame (30), the support (4) can rotate on the front horizontal bar (31) located on the bottom unit frame (30). It can be hinged.

However, in this case, excessive stress is concentrated on the horizontal bar 31 to which the support portion 4 is coupled, and there is a risk that the horizontal bar 31 may be deformed. In addition, when the inclined reinforcement (5) is removed, the support portion (4) rotates freely, making it difficult to transport the fall-prevention temporary structure (2).

Therefore, the rear of the support portion 4 can be positioned on the lowermost unit frame 30 and simultaneously fixed to the horizontal bar 31 located at the front and rear of the lowermost unit frame 30.

Accordingly, since the support portion 4 is supported at two points on the unit frame 30, the support portion 4 and the unit frame 30 can be firmly fixed.

A fastening hole (H) may be formed in the support portion (4) at a position corresponding to the position of the fastening hole (H) formed in the horizontal bar (31) of the lowermost unit frame (30) to be joined. In addition, the supporting members 4 and the horizontal bar 31, which are adjacent up and down, can be joined to each other by passing the fastening member 7 through the fastening hole H of the horizontal bar 31.

As shown in FIG. 10, the fastening hole (H) of at least one of the horizontal bars (31) coupled to the support portion (4) has a hole that penetrates the support portion (4) and is embedded in the lower ground. The fixed spike (6) can be fastened.

Some or all of the fastening members (7) fastened to join the support portion (4) and the horizontal bar (31) can be replaced with fixed spikes (6).

That is, the fixing spike 6 may be fastened through the horizontal bar 31 and the support portion 4, but the lower end of the fixing spike 6 may be formed to protrude from the lower surface of the support portion 4.

Then, the fixing spikes (6) not only connect the horizontal bar (31) and the support portion (4) to each other, but also simultaneously perform the role of fixing the fall-prevention temporary structure (2) to the ground to prevent it from sliding due to lateral force. You can.

Figures 11 to 16 are diagrams showing an example of the assembly sequence of a temporary structure to prevent construction equipment from falling.

Referring to FIGS. 11 to 16, when the support frame 3 is formed by combining a plurality of unit frames 30 up, down, left, and right, the assembly sequence of the construction equipment tipping prevention temporary structure 2 of the present invention will be described.

First, a rectangular parallelepiped-shaped unit frame 30 consisting of a plurality of horizontal bars 31 and vertical bars 32 is manufactured or prepared (FIG. 11).

Then, the unit frame 30 and the support portion 4 are assembled together (Figure 12). At this time, since the fixing spikes 6 may protrude from the lower portion of the support portion 4, the support portion 4 is erected vertically and assembled with the unit frame 30.

Thereafter, the unit frames 30 to which the support portion 4 is coupled are assembled together in the horizontal direction (FIG. 13). At this time, the neighboring unit frames 30 are joined by fastening the fastening members 7 to the fastening holes H with the coupling plates 34 of the horizontal bars 31 on both sides overlapping. Accordingly, a pair of support parts 4 are spaced apart from each other so that the left and right wheels of the construction equipment 1 are mounted.

Next, the assembly of FIG. 13 in which the support part 4 is provided in the vertical direction is rotated 90 degrees and installed so that the support part 4 is located on the upper surface of the ground (Figure 14).

Then, the entry slope part 41 is coupled to the front end of the support part 4, and the upper unit frame 30 is stacked and coupled to the upper part of the lower unit frame 3 (FIG. 15). Here, the upper and lower unit frames 30 can be joined to each other by fastening the fastening members 7 to the fastening holes H of the horizontal bars 31 adjacent to each other.

Finally, assembly of the construction equipment tipping prevention temporary structure (2) of the present invention is completed by combining the inclined reinforcement bar (5) between the support portion (4) and the support frame (3) (FIG. 16).

The construction equipment toppling prevention temporary structure of the present invention consists of a support frame installed on the upper surface of the ground at the boundary of the work site and a pair of supports that are protruding from the front of the support frame and onto which the wheels of the construction equipment are seated. The support frame is used to support the work site. Since it is simply mounted on the top of the ground at the boundary of the site, it is very easy to install and dismantle, and it has industrial applicability in that it can be operated variably according to the size or load of construction equipment.
