Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically to a foundation pit guardrail for building construction. Background Technology

[0002] Building construction is a production activity that transforms design drawings into physical objects. It encompasses the entire process from construction preparation to final acceptance, involving multiple stages such as foundation engineering, main structure construction, roofing and decoration engineering. It requires the application of theories such as mechanics of materials to solve technical problems and ensure project quality and safety. During the construction process, foundation pits are usually excavated. To prevent personnel and vehicles from falling into the pit, guardrails need to be installed around the perimeter of the pit to implement protective measures for the pit's edges. Currently, guardrails typically consist of two parts: a mesh fence and posts. The posts are fixed to the mesh fence on both sides with multiple bolts (generally, more than four bolts are needed on each side of the post to fix two mesh fences). However, this method of installing the mesh fence and posts is relatively cumbersome, wastes a lot of workers' time, and is inefficient, and needs improvement. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a foundation pit guardrail for building construction, so as to solve the problems existing in the background art.

[0004] This utility model provides the following technical solution: a foundation pit guardrail for building construction, comprising a mesh guardrail, with posts on both sides of the mesh guardrail, limit slots on both sides of the posts, limit rods fixedly installed on both sides of the mesh guardrail, the outer wall of the limit rods inserted into the interior of the limit slots, a limit cap threaded onto the top of the posts, the bottom of the limit cap overlapping the side of the top of the mesh guardrail, a warning board fixedly installed on the top of the mesh guardrail, a warning slogan provided in the center of the front of the warning board, a rigid water pipe fixedly installed above the warning board, multiple atomizing nozzles fixedly installed on the front of the rigid water pipe, the atomizing nozzles communicating with the interior of the rigid water pipe, and a flexible metal hose provided at the right end of the rigid water pipe.

[0005] Furthermore, a fixing block is welded to the bottom end of the column, and the fixing block has an installation hole inside.

[0006] Furthermore, protective grooves are provided on both sides of the front of the warning board, and reflective strips are fixedly installed inside the protective grooves.

[0007] Furthermore, a transparent plate is fixedly installed on the front side of the inner wall of the protective groove, and the transparent plate is located in front of the reflective strip.

[0008] Furthermore, a No. 1 pipe connector is installed at one end of the metal flexible hose, one end of the No. 1 pipe connector is installed at the right end of the rigid water pipe, and a No. 2 pipe connector is installed at the other end of the metal flexible hose.

[0009] Furthermore, a fixing frame is fixedly installed on the back of the mesh fence.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. This utility model, through the cooperation of limiting slots on both sides of the column and limiting rods on the sides of the two mesh guardrails, can initially restrict the two mesh guardrails to both sides of the column. With the setting of limiting caps, they can be spirally installed on the top of the column, so that the two bottoms of the limiting caps press down on the top of the two mesh guardrails, which facilitates quick and easy limiting and fixing of the mesh guardrails on both sides of the column. This method facilitates the installation of the mesh guardrails on both sides of the column, thereby saving workers' time and improving installation efficiency.

[0012] 2. This utility model uses a warning board to easily alert nearby people, and the reflective strips improve nighttime visibility. The combination of the protective groove and the transparent plate helps to protect the reflective strips and prevents environmental pollution from affecting their service life.

[0013] 3. This utility model uses a combination of a metal flexible hose, a No. 1 pipe connector, and a No. 2 pipe connector to facilitate the connection of rigid water pipes above two guardrails. Water is then pumped into the rigid water pipes using external pumping equipment and sprayed out through atomizing nozzles, which facilitates dust suppression near the guardrails.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The foundation pit guardrail for building construction involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1:

[0024] like Figure 1-7 As shown, a foundation pit guardrail for construction includes a mesh guardrail 1, a fixing frame 12 fixedly installed on the back of the mesh guardrail 1, posts 2 on both sides of the mesh guardrail 1, limit slots 5 on both sides of the posts 2, limit rods 4 fixedly installed on both sides of the mesh guardrail 1, the outer wall of the limit rods 4 being inserted into the inside of the limit slots 5, a limit cap 3 threadedly fitted onto the top of the posts 2, the bottom of the limit cap 3 overlapping the side of the top of the mesh guardrail 1, and a fixing pier 21 welded to the bottom of the posts 2, with an installation hole inside the fixing pier 21.

[0025] In this embodiment, the mesh fence 1 includes a metal frame and a metal mesh. The metal mesh is fixedly installed inside the metal frame, and the fixing frame 12 is installed inside the metal frame and located behind the metal mesh. At the same time, the front of the fixing frame 12 is welded to the back of the metal mesh. The fixing frame 12 is used to protect the back of the metal mesh and increase the strength of the metal mesh. By inserting the limiting rods 4 on the sides of the two mesh fences 1 into the limiting slots 5 on both sides of the column 2, the mesh fences 1 are initially limited. Then, the limiting caps 3 are screwed onto the top of the column 2, and the two sides of the bottom of the limiting caps 3 are pressed down on the top of the two mesh fences 1, which facilitates the quick limitation and fixation of the mesh fences 1 on both sides of the column 2. Through the setting of the mounting holes, bolts or other connecting parts can be used to fix the fixing piers 21 at the bottom of the column 2 onto the ground above the foundation pit.

[0026] Example 2:

[0027] like Figure 1-7As shown, a warning board 6 is fixedly installed on the top of the mesh fence 1. A warning slogan is provided in the center of the front of the warning board 6. Protective grooves 61 are provided on both sides of the front of the warning board 6. A reflective strip 63 is fixedly installed inside the protective groove 61. A transparent plate 62 is fixedly installed on the front of the inner wall of the protective groove 61. The transparent plate 62 is located in front of the reflective strip 63.

[0028] In this embodiment, the warning signs on the front of the warning board 6 facilitate warning and reminders to nearby personnel. The reflective strip 63 enhances the visibility of the guardrail in low-light environments by reflecting light, improves nighttime visibility, and reduces the risk of accidentally entering the construction area. The transparent board 62 can be fixedly glued to the inside of the protective groove 61 with waterproof adhesive, which facilitates the protection of the reflective strip 63 and prevents the reflective strip 63 from being affected by environmental pollution, thus affecting its service life.

[0029] Example 3:

[0030] like Figure 1-7 As shown, a rigid water pipe 7 is fixedly installed above the warning board 6. Multiple atomizing nozzles 8 are fixedly installed on the front of the rigid water pipe 7. The atomizing nozzles 8 are connected to the inside of the rigid water pipe 7. A metal flexible hose 9 is provided at the right end of the rigid water pipe 7. A first pipe connector 10 is installed at one end of the metal flexible hose 9. One end of the first pipe connector 10 is installed at the right end of the rigid water pipe 7. A second pipe connector 11 is installed at the other end of the metal flexible hose 9.

[0031] In this embodiment, the No. 1 pipe connector 10 and No. 2 pipe connector 11 at both ends of the metal flexible hose 9 can be connected to the rigid water pipes 7 above the two guardrails respectively. Water is pumped into the rigid water pipes 7 using external pumping equipment and sprayed out through multiple atomizing nozzles 8 to facilitate dust suppression near the guardrails.

[0032] In summary, as Figure 1-7 As shown, this type of foundation pit guardrail for construction uses the following steps: First, the limiting rods 4 on the sides of the two mesh guardrails 1 are inserted into the limiting slots 5 on both sides of the column 2 to initially limit the mesh guardrails 1. Then, the limiting caps 3 are screwed onto the top of the column 2, and the bottom sides of the limiting caps 3 are pressed down on the top of the two mesh guardrails 1, facilitating quick and easy limiting and fixing of the mesh guardrails 1 on both sides of the column 2. This method facilitates the rapid assembly of multiple mesh guardrails 1 and columns 2. By installing the No. 2 pipe connector 11 at one end of the metal flexible hose 9 onto one end of the rigid water pipe 7 above another guardrail, the rigid water pipes 7 above the two guardrails can be connected together. Water is then pumped into the rigid water pipe 7 using external pumping equipment and sprayed out through multiple atomizing nozzles 8 to facilitate dust suppression near the guardrails.

[0033] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The installation methods between equipment are also the same as conventional installation methods in the prior art. For example, the connection position of valve components is provided with anti-leakage rubber strips, the outside of threaded rods or lead rods is provided with dust covers, and the equipment can be driven by either built-in batteries or external power supply. The control method is automatic control by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, this utility model will not explain the control method and circuit connection in detail.
