Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of crash barrier construction, in particular to a construction residue collecting device for crash barrier construction. BACKGROUND

[0002] At present, in order to prevent vehicles from going out of the road, workers will set up crash barriers on both sides of the road during road construction. During the construction of the crash barrier, the workers first lay the reinforcement mesh on both sides of the road, then place the pouring mold at the reinforcement mesh, and finally pour the concrete into the mold. After the concrete solidifies, the mold is removed. When the workers pour the concrete into the mold, the concrete aggregate or slurry is easy to fall from the mold and pollute the ground. In order to facilitate cleaning afterwards, the workers will set up a protective shed at the construction site.

[0003] However, when workers construct roads in the air, such as viaduct construction, mountain-crossing road construction, etc., they mostly use precast box girder splicing construction, so they cannot set up a protective shed. When pouring the crash barrier on both sides of the precast box girder, the concrete aggregate or slurry is easy to fall from the outside of the crash barrier, causing unpredictable safety hazards to the vehicles passing below. SUMMARY

[0004] In view of the defects in the prior art that the construction residue generated during the pouring of the crash barrier when constructing the road in the air causes unpredictable safety hazards to the vehicles passing below, the present application provides a construction residue collecting device for crash barrier construction. It can collect construction residue and avoid damage to vehicles passing below during construction.

[0005] To solve the above technical problems, the present application uses the following technical scheme:

[0006] A construction residue collecting device for crash barrier construction includes a collecting device main body, which includes a collecting plate arranged on the outside of the crash barrier. One end of the collecting plate extends downward to the precast box girder. The one end of the collecting plate is bent inward to form a bent portion, and the two ends of the bent portion are provided with baffle plates. The baffle plates and the bent portion together form a collecting groove for collecting construction residue.

[0007] According to the present application, after the workers install the mold, they install the crash barrier outside the mold. Then, when the workers pour the concrete into the mold, the concrete aggregate or slurry that falls outside the mold is blocked by the baffle plates and falls into the collecting groove at the lower end of the baffle plates. This prevents the concrete aggregate or slurry from falling onto the road below, causing damage to the vehicles passing below and endangering the safety of the people in the vehicles. When the concrete aggregate or slurry falls inside the mold, it stays on the precast box girder, making it easy for the workers to clean up later.

[0008] As preferred, the crash barrier is provided with a fixing mechanism for fixing the collecting plate at the outer side wall of the crash barrier; the fixing mechanism comprises a support frame arranged at the outer side of the crash barrier; the support frame comprises a plurality of horizontal rods and longitudinal rods for connecting the horizontal rods; one end of the longitudinal rod is bent inward to form an installation cage for storing the bent part together with the horizontal rod; the other end of the longitudinal rod is bent to form a hook, and the hook is provided with a channel steel passing through the hook;

[0009] The crash barrier is provided with a plurality of connecting seats arranged at the upper end side wall of the crash barrier; the upper end of the crash barrier is provided with a connecting rod for connecting the channel steel and the connecting seat; the side wall of the crash barrier away from the connecting seat is provided with a fixing rod; the crash barrier is provided with a basket screw rod for connecting the fixing rod and the connecting seat; and the crash barrier is provided with a support rod between the crash barrier and the collecting plate.

[0010] According to the application, the staff first places the support frame outside the mold by the crane, then connects the channel steel and the connecting seat by the connecting rod, and then connects the fixing rod and the connecting seat by the basket screw rod, so as to fix the support frame; finally, the staff places the baffle in the support frame, thereby facilitating the staff to install the baffle; after the baffle is installed, the staff places the support rod between the baffle and the mold, so that there is a gap between the baffle and the mold, and the concrete aggregate or slurry can fall into the collecting groove through the gap;

[0011] After the concrete is solidified in the mold, the staff removes the support rod, lifts the support frame by the crane, and then removes the mold; after the mold is removed, the staff places the support frame, and then places the support rod between the baffle and the crash barrier; when the staff cleans the crash barrier, the concrete aggregate falling outside the crash barrier will fall into the collecting groove, thereby facilitating the staff to clean the crash barrier after pouring.

[0012] As preferred, the connecting seat comprises two parallel support plates, one end of the two support plates is recessed inward to form a groove for the edge of the crash barrier to extend into; one end of the support plate away from the groove is provided with a connecting plate for connecting the two support plates; the upper end of the connecting plate is provided with a first nut; the connecting rod is a threaded rod, one end of the threaded rod is matched with the first nut, and the other end of the threaded rod passes through the channel steel; one end of the threaded rod passing through the channel steel is provided with a second nut.

[0013] According to the application, when the staff connects the channel steel and the connecting seat, the threaded rod passes through the first nut and the channel steel, and then the second nut is rotated to pull the distance between the channel steel and the connecting seat, so that the connecting seat is clamped at the upper end side wall of the crash barrier, and then the connecting seat is pulled by the basket screw rod, thereby preventing the support frame from falling; when the support plate is arranged at the side wall of the crash barrier, the edge of the upper end of the crash barrier is clamped in the groove of the support plate, thereby preventing the connecting seat from sliding when being pulled.

[0014] Preferably, the support plate side wall is provided with a first through hole for the pull hook on the flower basket screw rod to pass through; the support plate side wall is also provided with a second through hole and a third through hole; the anti-collision guard rail is provided with a limiting rod at one end close to the connecting seat, the limiting rod passing through the second through hole.

[0015] According to the present application, before the concrete is poured into the mold, the staff needs to set the pull hook on the surface of the precast box girder, then hang the pull hook at one end of the flower basket screw rod on the pull hook on the precast box girder, pass the pull hook at the other end of the flower basket screw rod through the first through hole, rotate the second nut, adjust the distance between the channel steel and the connecting seat, make the connecting seat tightly abut against the mold, and connect the connecting seat and the mold through the bolts passing through the second through hole and the third through hole; thereby the connecting strength between the connecting seat and the mold is increased, and the connecting seat is prevented from falling off.

[0016] When the mold is removed, the limiting rod passes through the second through hole on all the connecting seats, thereby preventing the single connecting seat from shaking when being pulled, and improving the stability of the fixing mechanism as a whole.

[0017] Preferably, the connecting plate and the upper end surface of the precast box girder are provided with a support column arranged obliquely.

[0019] Preferably, the end of the connecting plate away from the first nut is provided with an inclined surface; the end of the support column close to the connecting plate is provided with a flange abutting against the inclined surface.

[0020] According to the present application, the flange at one end of the support column abuts against the inclined surface of the connecting plate, thereby increasing the contact area between the connecting plate and the support column, and preventing the support point from being damaged due to excessive pressure.

[0021] Preferably, the end of the support rod close to the anti-collision guard rail is provided with a rubber pad.

[0022] According to the present application, after the mold is removed, the staff places the rubber pad on the end surface of the support rod in contact with the anti-collision guard rail, thereby preventing the contact point of the support rod and the anti-collision guard rail from being damaged due to excessive pressure.

[0023] Preferably, the collecting plate is provided with a plurality of sleeves at the end surface close to the anti-collision guard rail.

[0024] According to the present application, before the crane lifts the support frame, the staff needs to insert a round rod into the sleeve, and support the end of the round rod at the side wall of the precast box girder, thereby preventing the collecting plate and the side wall of the precast box girder from being scratched during the movement of the support frame.

[0025] Preferably, the baffle is provided with a discharging hole, a stand is arranged at the upper end of the discharging hole, and a blocking plate for blocking the discharging hole is arranged at the hole of the discharging hole, and the upper end of the blocking plate is provided with a sleeve ring sleeved on the stand.

Both ends of the bent portion 740 are provided with baffles 730. The baffles 730 and the bent portion 740 together constitute a collection trough 750 for collecting construction waste.

[0043] In this embodiment, after the mold is installed, the crash barrier 120 is installed on the outside of the mold. When the concrete is poured into the mold, if concrete aggregate or slurry falls into the outside of the mold, it will be blocked by the baffle 730 and fall into the collection trough 750 at the lower end of the baffle 730. This prevents concrete aggregate or slurry from falling into the road below, causing damage to passing vehicles and endangering the safety of people inside the vehicles. When concrete aggregate or slurry falls into the inside of the mold, it will remain on the precast box girder, making it convenient for the workers to clean up later.
