Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to the construction of horizontal openings such as elevator shafts. Specifically, the utility model is an adjustable horizontal opening protection device. Background Technique

[0002] During the modern building construction process, the construction of facilities such as horizontal openings is often encountered, or there are horizontal openings that cannot be blocked or closed temporarily during the intermediate process of construction, such as elevator shafts. At this time, a temporary protection device needs to be set at the opening to prevent construction workers or other people or objects from falling into the opening and ensure the safety of construction. Due to different construction projects and types, the size of the opening for each construction is also different. The disadvantage of the existing opening protection device in construction is that its fixed-size design results in poor adaptability in different projects and cannot meet the protection requirements of openings of various specifications. After each construction is completed and removed, it cannot be reused, thus causing waste of resources and reduction of construction efficiency. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the defects of the single-shaped protection size, low utilization rate, and inconvenient turnover of the horizontal opening protection device in the prior art during the construction process, and to provide an adjustable horizontal opening protection device. The purpose of the utility model is achieved through the following technical solutions.

[0004] An adjustable horizontal opening protection device includes an adjustable frame and a wire mesh installed on the adjustable frame. The adjustable frame includes 4 cross-shaped keels connected end to end in sequence; each cross-shaped keel is composed of two mutually perpendicular installation keels and two mutually perpendicular support keels intersecting at the cross-shaped center; the two mutually perpendicular installation keels are respectively a core body and a sleeve. The outer diameter of the core body is smaller than the inner diameter of the sleeve. A plurality of bolt installation holes arranged in a straight line are sequentially arranged along the length direction of the core body on the core body. Through holes with the same opening direction and size as the bolt installation holes are arranged on the sleeve. The core body of each cross-shaped keel is inserted into the sleeve of another cross-shaped keel and connected by bolts. The core body of the keel of another cross-shaped frame is inserted into the sleeve of each cross-shaped frame and connected by bolts.

[0005] Further optimization, the wire mesh is connected to the adjustable frame by bolts.

[0006] Further, the length of the support keel is shorter than that of the installation keel. The two support keels are welded to the installation keel or one of the support keels is integrally formed with the installation keel.

[0007] Further, the core body and the sleeve are welded together.

[0008] Further, the sleeve is a square steel pipe, and the core is a square steel pipe.

[0009] In another optimization, mounting grooves are provided on the side walls of each cruciform keel, and the mounting grooves are arranged in pairs. Each pair of mounting grooves are respectively distributed on the core and the sleeve of the same cruciform keel and are equidistant from the cruciform center.

[0010] Further, a protective rod is installed between the mounting groove on one sleeve and the mounting groove on the core at the opposite position.

[0011] Further, the mounting groove penetrates through the side wall of the cruciform keel, and bolt mounting holes that penetrate up and down are provided at the position of the mounting groove.

[0012] Advantages of the present utility model:

[0013] For the horizontal opening protection device of the present utility model, through the docking between the core and the sleeve of the cruciform keel, the size of the frame can be adjusted telescopically according to actual needs, realizing an adjustable frame design and being able to adapt to horizontal openings of different sizes.

[0014] By adjusting the length of the mounting keel with bolts and welding support keels at the four corners, the stability of the keel after adjustment is ensured, preventing displacement during the construction process. After the protection task is completed, only need to loosen the bolts to disassemble the frame into four cruciform keels for storage or transportation, which is convenient for the next construction use. Moreover, each cruciform keel can be made into exactly the same shape and size, and can be combined arbitrarily, making production and installation very convenient and having good versatility.

[0015] Compared with the traditional fixed horizontal opening protection device, the protection device of the present utility model improves the applicable range of opening protection, increases the turnover and utilization rate of opening protection, reduces costs and improves construction efficiency at the same time.

[0025] Embodiment 1

[0026] As Figures 1 to 4 shown, an adjustable horizontal opening protection device includes an adjustable frame 1 and a wire mesh 2 installed on the adjustable frame 1. The wire mesh 2 can be connected to the frame by bolts for easy disassembly, or other installation forms can be selected.

[0027] The adjustable frame 1 includes 4 cross-shaped keels connected end to end in sequence; as Figure 2 , 3 shown, each cross-shaped keel is composed of two mutually perpendicular installation keels and two mutually perpendicular support keels 11 that intersect at the cross-shaped center. Each cross-shaped keel can be made into completely identical components, which is convenient for manufacturing and also convenient for storage after disassembly. The length of the support keel 11 is shorter than that of the installation keel, and the two support keels 11 are welded to the installation keel or one of the support keels 11 is integrally formed with the installation keel.
