Description

Technical Field

[0001] This scheme belongs to the field of prefabricated building design and construction, and specifically involves a prefabricated concrete foundation for temporary enclosure of a construction site. Background Art

[0002] As the future development direction of the construction industry, prefabricated buildings are one of the most effective ways to achieve the industrialization of construction, which is conducive to improving production efficiency. At present, my country is vigorously promoting the development of prefabricated buildings, and prefabricated concrete components are widely used. Prefabricated prefabricated concrete wall foundation is one of the typical cases of prefabricated prefabricated building technology application. The prefabricated prefabricated wall foundation is composed of four prefabricated wall foundation structures. In addition to meeting the requirements for the use of prefabricated structures, it also follows the design principles of "integration", "standardization", "modularization" and "universalization", and improves construction efficiency and reduces costs through fewer specifications and more combinations.

[0003] However, the traditional connection method between the prefabricated foundation fence and the fence pole is that the prefabricated foundation fence is provided with a threaded hole, and the fence pole is provided with an external thread. The fence pole is rotated by manual operation to tighten and fix the thread, which is time-consuming and laborious. Summary of the invention

[0004] The purpose of this scheme is to provide a precast concrete foundation for temporary enclosures on construction sites that is easy to fix, so as to solve the problem of manually fixing and tightening multiple fence poles.

[0005] In order to achieve the above-mentioned purpose, this scheme provides a precast concrete foundation for temporary enclosure of a construction site. It includes: a fence pole and a prefabricated fence foundation; the prefabricated fence foundation includes: prefabricated assembled fence foundation No. 1, prefabricated assembled fence foundation No. 2, prefabricated assembled fence foundation No. 3 and prefabricated assembled fence foundation No. 4; the prefabricated fence foundation is assembled in sequence according to prefabricated assembled fence foundation No. 1, prefabricated assembled fence foundation No. 2, prefabricated assembled fence foundation No. 3 and prefabricated assembled fence foundation No. 4; the prefabricated fence foundation is provided with a fixing hole; the fence pole is matched with the fixing hole; the fence pole is provided with a card slot; the prefabricated concrete foundation of the temporary fence at the construction site also includes: a first spring, a connecting rod, a positioning shaft, a second spring and a third spring; the first spring is arranged in the fixing hole; the positioning shaft is fixedly connected to the prefabricated fence foundation; the connecting rod is rotatably connected to the positioning shaft; the connecting rod is in contact with the first spring; one end of the second spring is fixedly connected to the prefabricated fence foundation, and the other end is fixedly connected to the connecting rod; the free end of the connecting rod is arc-shaped; the free end of the connecting rod is engaged with the card slot.

[0006] Principle of this scheme: The prefabricated fence foundations are assembled in sequence according to prefabricated assembled fence foundation No. 1, prefabricated assembled fence foundation No. 2, prefabricated assembled fence foundation No. 3 and prefabricated assembled fence foundation No. 4, and the fence rod is placed in the fixing hole. The first spring is forced to move downward, pushing the connecting rod to move. Under the action of the positioning shaft, the free end of the connecting rod is tilted and stuck into the slot of the fence rod, thereby fixing the fence rod and the prefabricated fence foundation.

[0007] Beneficial effects of this solution: Compared with the traditional locking method, this solution uses the gravity of the fence pole itself and cooperates with the prefabricated fence foundation to achieve automatic locking, thereby reducing manual operation. The prefabricated fence foundation is factory-made, which reduces on-site operations and can efficiently control the operation time; it can not only be mass-produced, but also prefabricated in advance, ensuring quality, saving time, and simplifying the construction and installation steps, which improves assembly efficiency. At the same time, it reduces the disharmony brought by infrastructure construction to the surrounding environment and greatly improves the success rate of infrastructure construction.

[0008] Furthermore, the slot is set to be "L"-shaped. When the fence rod moves downward, the spring is squeezed, the free end of the connecting rod is tilted, and is inserted into the slot of the fence rod. The fence rod is rotated to make the connecting rod fall into the groove of the slot, preventing the fence rod from rotating and causing the railing to slide out of the slot, while locking the connecting rod.

[0009] Furthermore, a warning sign is provided outside the second prefabricated fence foundation; a pressure sensing device is provided on the ground outside the second prefabricated fence foundation, and the pressure sensing device includes: a pressure plate, a second spring and a pressure sensor; a wire is provided inside the connecting rod; the second spring is fixedly connected to the pressure plate; the pressure sensor is arranged below the second spring; a battery is provided inside the fence pole; a conductive contact piece is provided inside the slot of the fence pole; the battery, the contact piece, the warning sign and the pressure sensing device are connected by a wire; the warning sign is connected in series with the pressure sensing device, and when a pedestrian passes by outside the construction fence, the gravity sensing device is subjected to pressure, thereby conducting the circuit, and then the warning sign lights up, reminding passers-by to stay away from the construction site and avoid danger. At the same time, the warning sign lights up when pedestrians pass by, and does not light up when no one is around, thereby saving power and avoiding waste of resources.

[0010] Furthermore, a warning sign is provided outside the prefabricated fence foundation No. 4; a photoresistor is provided on the prefabricated fence No. 4; a battery is provided in the fence pole; a conductive contact piece is provided in the fence pole slot; the battery, contact piece, warning sign and photoresistor are connected by a wire; the warning sign is connected in parallel with the photoresistor, and when there is sunlight during the day, the resistance of the photoresistor decreases, the current increases, the circuit is turned on, the warning sign is short-circuited, and will not light up; at night when there is no sunlight, the resistance of the photoresistor increases, the circuit is disconnected, and the warning sign is connected, thereby lighting up, with the purpose of reminding pedestrians to avoid the construction site at night.

Not only can it be mass-produced, but it can also be prefabricated in advance, which ensures quality, saves time, and simplifies the construction and installation steps, which improves assembly efficiency.

[0025] As attached Figure 2 As shown:

[0026] Prefabricated assembled fence foundation No. 14 is a rectangular structure, in which a rectangular body with reserved connection holes is embedded, and the material is all concrete.

[0027] As attached Figure 3 As shown:

[0028] The cross-sectional shape of the prefabricated assembled wall foundation No. 2 15 foundation body is an equilateral trapezoid. Wall grooves are set at both ends of the foundation body wall foundation plate. There is a groove on the left side and a groove on the right side, and there is a reserved connection hole in the groove on the right side. Two hanging nails are installed on the wall foundation for construction and lifting.

[0029] As attached Figure 4 As shown:

[0030] A fixing hole is provided on the prefabricated fence foundation 2, and the fence rod 1 is arranged in the fixing hole. A first spring 4 is provided in the prefabricated fence foundation 2, and the first spring 4 is arranged below the fixing hole, and the first spring 4 is in contact with the fence rod 1. A connecting rod 3 is provided below the first spring 4 to contact the first spring 4, and a third spring 13 is provided below the connecting rod 3 and fixedly connected to the connecting rod 3, and the other end of the third spring 13 is fixedly connected to the prefabricated fence foundation 2. A fixedly connected positioning shaft 5 is provided on the prefabricated fence foundation 2, and the connecting rod 3 is hinged to the positioning shaft 5, and the positioning shaft 5 is arranged between the connecting rods 3.

[0031] As attached Figure 5 As shown:

[0032] The cross-sectional shape of the main body of the prefabricated assembled wall foundation No. 3 16 structural foundation is a non-standard "L"-shaped section. There are reserved connection holes on the upper part of the structure for inserting steel bars to facilitate connection with other prefabricated wall foundations.

[0033] As attached Figure 6 As shown:

[0034] The cross-sectional shape of the prefabricated assembled wall foundation No. 4 17 foundation body is an equilateral trapezoid. Wall grooves are set at both ends of the foundation body wall foundation plate, and there are reserved connection holes. The wall foundation is equipped with two hanging nails for construction and hoisting.

[0035] like Figure 7-Figure 9 As shown:

[0036] A wire 11 is provided in the connecting rod 3, a slot 12 is provided on the fence rod 1, a contact piece 6 with conductive properties is provided in the slot 12, and a battery 7 of about 5V is provided in the fence rod 1, which is only used for the operation of the warning sign 8. The contact pieces 6 in the slots 12 at both ends are externally connected to the wire 11, and the lead-out wire 11 is connected to the battery 7. A warning sign 8 is fixedly connected to the prefabricated fence foundation 2, and the warning sign 8 is provided with a connector, which is connected through the wire 11. A pressure sensing device is provided within one meter of the ground outside the prefabricated fence foundation 2, including a second spring 9 and a pressure sensor 10, the connector of the warning sign 8 is connected to the pressure sensor 10 through the wire 11, and the warning sign 8 is connected to the second spring through the wire 11. When the fence rod 1 is inserted into the fixing hole, the first spring 4 moves downward, thereby pushing the connecting rod 3 to move downward. Under the action of the positioning shaft 5, the other end of the connecting rod 3 is tilted, and then stuck in the slot 12, and the fence rod 1 is rotated to make the connecting rod 3 stuck in the groove part on the slot 12, thereby ensuring that the fence rod 1 will not pop out of the fixing hole. When the connecting rod 3 is stuck to the fence rod 1, the connecting rod 3 contacts the contact piece 6, and the wire 11 is connected. When the ground is under pressure, the second spring 9 moves downward and contacts the pressure sensor 10, thereby forming a closed loop. The pressure sensing device is connected in series with the warning sign, the circuit is turned on, and the warning sign 8 lights up. When there is no pressure, the second spring 9 does not contact the pressure sensor 10, the circuit is disconnected, and the warning sign 8 light does not light up.

[0037] Prefabricated fence foundation 2 Other warning signs 8 are connected to photoresistors, which are connected in parallel with warning signs 8. When there is light, the resistance of the photoresistor decreases, the parallel circuit is turned on, and the warning sign 8 is short-circuited, so it does not light up. On the contrary, when there is no light, the resistance of the photoresistor increases, the parallel circuit is disconnected, and the warning sign 8 is connected, so it lights up to remind pedestrians.

[0038] like Fig.10 As shown:

[0039] A warning sign 8 is provided outside the prefabricated assembled fence foundation No. 4 17, a photoresistor 18 is provided on the prefabricated assembled fence foundation No. 4 17, a battery 7 is provided in the fence pole 1, and a conductive contact piece 6 is provided in the slot 12 of the fence pole 1. The battery 7, the contact piece 6, the warning sign 8 and the photoresistor 18 are connected by a wire 11, and the warning sign 8 is connected in parallel with the photoresistor 18. When there is sunlight during the day, the resistance of the photoresistor 18 decreases, the current increases, the circuit is turned on, the warning sign 8 is short-circuited, and thus will not light up; at night when there is no sunlight, the resistance of the photoresistor 18 increases, the circuit is disconnected, and then the warning sign 8 is connected, thereby lighting up, the purpose is to remind pedestrians to avoid the construction site at night.

[0040] The operation method of this scheme is as follows: the fence rod 1 is inserted into the fixing hole, the first spring 4 moves downward, and under the action of the positioning shaft 5, the arc-shaped end of the connecting rod 3 is tilted up and inserted into the slot 12 of the fence rod 1, and the fence rod 1 is rotated to make the connecting rod 3 fall into the groove of the slot 12.

[0041] During daytime construction, a pedestrian walks by the prefabricated fence foundation 2 and steps on the pressure sensing device, causing the second spring 9 to contact the pressure sensor 10, thereby conducting the circuit and lighting up the warning sign 8 to alert the pedestrian.

[0042] When resting at night, due to the dim light, the photoresistor is not irradiated by the light source, the parallel circuit is disconnected, and the warning sign 8 is always on to remind pedestrians.

[0043] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
