Description

Technical Field

[0001] The utility model relates to the field of construction safety, in particular to a construction channel for quickly assembling a steel bar bottom plate end. Background Art

[0002] During the foundation construction process of buildings or structures, the concrete is often poured in sections. The bottom plate steel bars will be exposed at the ends of the positions where the concrete has been poured. In order to prevent the bottom plate steel bars from being damaged by trampling or mechanical collision, it is necessary to set up ladders or construction passages at the ends of the bottom plate steel bars to facilitate workers to move between the poured and unpoured positions. Currently, most people use wooden boards or iron plates to place them between the poured and unpoured positions to simply build inclined construction passages. However, such passages have poor stability and are not easy to recycle in the later stage, resulting in a waste of resources. Utility Model Content

DETAILED DESCRIPTION

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] like Figure 1-3 As shown, a fast-assembly steel bar bottom plate end construction channel includes several sections of precast panels 1. The two ends of the precast panels 1 are respectively provided with an integrally formed protrusion 8 and groove 7. Adjacent precast panels 1 are butted together through the protrusions 8 and grooves 7. Circular holes 9 that pass through the protrusions 8 and grooves 7 are provided on the sides of the protrusions 8 and grooves 7. The circular holes 9 on the protrusions 8 and grooves 7 correspond to each other. The circular holes 9 are arranged along the width direction of the precast panels 1. After the adjacent precast panels 1 are butted together through the protrusions 8 and grooves 7, the adjacent precast panels 1 are fixed together by the pins 10 that pass through the circular holes 9 of the protrusions 8 and grooves 7. Several sections of precast panels 1 are assembled to form the bottom horizontal channel part and placed in a position where no concrete has been poured. To further ensure the safety of workers, guardrails 3 are preferably installed on both sides of the prefabricated panel 1. The guardrail 3 is preferably installed in such a way that square grooves 11 for screw installation are provided on both sides of the upper surface of the prefabricated panel 1. The bottom of the guardrail 3 is a square block that matches the square groove 11. The bottom of the guardrail 3 is inserted into the square groove 11 to achieve quick installation of the guardrail 3.

[0019] This embodiment also includes an inclined channel portion, which is a ladder 4. The ladder 4 can be an iron ladder or a wooden ladder commonly used on construction sites. Preferably, railings are provided on both sides of the ladder 4. A protrusion 8 or a groove 7 is also provided at the bottom end of the ladder 4. Similarly, a circular hole 9 is provided on the side of the protrusion 8 or the groove 7. The ladder 4 and the prefabricated plate 1 are also fixedly connected by docking the protrusion 8 and the groove 7 and passing the pin 10 through the circular hole 9. No further details are given here. Fixed ears 5 installed with screws are provided downward on both sides of the bottom surface of the ladder 4. The fixed ears 5 are fixedly connected to the piston rod of the hydraulic cylinder 6 below. Preferably, the base of the hydraulic cylinder 6 adopts an enlarged foundation to increase the stability of the placement of the hydraulic cylinder 6. In this embodiment, a hydraulic cylinder 6 is provided at the upper and lower positions of the ladder 4, and a total of four hydraulic cylinders 6 are provided.

[0020] A board 2 is rotatably connected to the upper end of the ladder 4. The board 2 can be connected by a hinge or an axis. There are no excessive restrictions here. The board 2 is used to be placed on the upper surface of the end bottom plate steel bars and the upper surface of the cast foundation. The board 2 is the upper horizontal channel part.

[0021] To further enhance the stability of the entire device, a counterweight design can be preferably added to the bottom horizontal channel portion. The interior of the precast panel 1 is designed as a hollow structure, with an inner groove 12 provided within the precast panel 1. A guide plate 13 is fixed to the inner groove 12 via screws. The guide plate 13 is tilted and tilts downward toward a discharge port 15, which is located on the side of the precast panel 1. Two inclined plates 14 are fixed to the upper surface of the guide plate 13, forming a funnel shape. The narrow opening formed by the two inclined plates 14 faces the discharge port 15. A feeding port is provided on the upper surface of the precast panel 1, which is not shown in the accompanying drawings. The discharge port 15 and the feeding port are sealed with screw plugs when the channels are in normal use.

[0022] When in use, several sections of prefabricated panels 1 are spliced ​​at the uncast position, the protrusions 8 and grooves 7 of the prefabricated panels 1 are docked together, and then the pins 10 are passed through the round holes 9 to fix the prefabricated panels 1 together. Then the guardrails 3 are inserted into the square grooves 11 on both sides of the prefabricated panels 1, the feeding port on the upper surface of the prefabricated panels 1 is opened, and sand is injected into the interior of the prefabricated panels 1 from the feeding port. At this time, the discharge port 15 on the side of the prefabricated panels 1 is blocked, and the sand is located in the cavity inside the guide plate 13 and the prefabricated panels 1. Then the ladder 4 is placed, and the lower end of the ladder 4 is docked with the prefabricated panels 1. The inclination of the ladder 4 is adjusted so that the plank 2 can be placed on the upper surface of the cast foundation. On the top, rotate the scaffolding 2 so that it can be placed horizontally on the upper surface of the poured foundation, then pass the pin 10 through the circular hole 9 of the ladder 4 and the precast plate 1 to fix the lower end of the ladder 4 and the precast plate 1 together. At this time, place the hydraulic cylinder 6 under the fixed ear 5 of the ladder 4, raise and lower the piston rod of the hydraulic cylinder 6 to the position of the fixed ear 5, and then fix the upper end of the piston rod of the hydraulic cylinder 6 to the fixed ear 5. Use the hydraulic cylinder 6 to support the ladder 4 to complete the installation of the channel. Workers can use the channel to cross between the uncast and cast foundations to carry out other construction, and there will be no collision or damage to the end bottom plate steel bars during construction. When not in use, open the discharge port 15 to let the sand in the precast plate 1 flow out, and then gradually dismantle the channel.

[0023] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, based on the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, replacements and variations made to the implementation methods are still within the scope of protection of the present invention.
