Description

Technical Field

[0001] The utility model belongs to the field of construction equipment, and in particular relates to a support frame base structure for inclined floors. Background Art

[0002] When using a lattice support frame or a tower crane standard section support frame on a sloped floor, the traditional leveling method is usually to use materials already on site to extend the vertical rods to achieve the leveling effect, but this on-site adjustment method is difficult to guarantee the leveling accuracy. Moreover, because the contact between the support frame and the floor is usually a single-point contact, after the load is applied, it is easy to damage the concrete surface layer and waterproof layer of the floor. After the support frame is unloaded, the concrete surface layer and waterproof layer need to be repaired, which affects the on-site construction progress. Therefore, there is an urgent need to develop a support frame base structure that can reduce damage to the original inclined floor. Utility Model Content

DETAILED DESCRIPTION

[0027] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of the specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. The technical features of the various embodiments of the present invention may be combined accordingly, provided that there is no conflict between them.

[0028] like Figure 1As shown, as a preferred embodiment of the present invention, this embodiment provides a support frame base structure for inclined floors, including an inner frame structure 1, an adjustment plate 2 and a formwork structure 3. In the device provided by the present invention, the inner frame structure 1 is an integral frame structure composed of 4 H-shaped steels. In other embodiments, the inner frame structure 1 can also be an integral frame structure composed of square tube channel steel or other suitable steel sections. The inner frame structure 1 is arranged above the inclined floor 4, and a number of adjustment plates 2 are arranged between the inner frame structure 1 and the upper surface of the inclined floor 4. The adjustment plates 2 are used for leveling so that the support frame 5 can adapt to the slope of the floor. There is a certain distance between each adjustment plate 2, so that when the concrete base 6 is poured later, the concrete can flow smoothly from the interval space between the adjustment plates 2. Considering the stability, welding is usually used to fix it to the inner frame structure 1. Formwork structure 3 is the formwork framework for casting the concrete base 6. It includes an outer frame structure, height adjustment rods 33, and fixing rods 34. The outer frame structure is arranged outside the inner frame structure 1. The outer structure is composed of a first form 31 and a second form 32 as a single frame structure. The first form 31 is vertically installed on the inclined floor 4, perpendicular to the horizontal plane, while the second form 32 is fixed perpendicular to the upper surface of the inclined floor 4. This arrangement facilitates casting a concrete base 6 that matches the slope of the inclined floor 4.

[0029] like Figure 2 As shown, each leveling plate 2 is a right-angled triangular plate, including a first right-angled side 2-1, a second right-angled side 2-2, and a hypotenuse 2-3. The hypotenuse 2-3 contacts and is fixed to the upper surface of the inclined floor to prevent the impact of concrete during concrete pouring from causing the position of the leveling plate 2 and the inner frame structure 1 fixed to the leveling plate 2 to change. The angle between the hypotenuse 2-3 and the second right-angled side 2-2 is adjusted according to the slope of the inclined floor 4 to ensure that the inner frame structure 1 fixed above the second right-angled side 2-2 is in a horizontal state, so that the support frame 5 installed on the upper surface of the inner frame structure 1 is perpendicular to the ground after installation, increasing the stability of subsequent equipment installation. The welding work between the leveling plate 2 and the inner frame structure 1 can be processed in the factory. The standardized operation of the trimming and welding work of the leveling plate 2 improves the leveling accuracy of the support frame 5 to a certain extent, and it can be used directly at the construction site, reducing the time for on-site adjustment. When in use, the combined structure of the adjustment plate 2 and the inner frame structure 1 welded together after being trimmed according to the angle of the inclined floor 4 is directly placed on the inclined floor 4 .

[0030] like Figure 3As shown, the two ends of the first template 31 of the template structure 3 are bent at right angles in the same direction to form a bent plate, which is provided with holes for connecting with the second template 32. The second template 32 is a common square plate, and its two ends are also provided with holes that match the holes on the bent plate of the first template 31. In order to increase stability, the first template 31 and the second template 32 are both made of steel. Figure 4 As shown, the bottom of the height adjustment rod 33 is fixedly mounted on the end of the first formwork 31. The height adjustment rod 33 is arranged vertically upward, and a fixing rod 34 is mounted on the other end. Several mounting holes are provided on the height adjustment rod 33 along the height direction to adjust the mounting position of the fixing rod 34. One end of the fixing rod 34 is fixedly connected to the height adjustment rod 33, and the other end is fixedly connected to the upper surface of the inner frame structure 1 via bolts. This facilitates the removal of the formwork structure 3 after the concrete base 6 is poured. The mounting position of the fixing rod 34 on the height adjustment rod 33 can be adjusted according to the height of the upper surface of the inner frame structure 1. Both the height adjustment rod 33 and the fixing rod are made of angle steel or channel steel. To enable formwork reuse and reduce construction costs, the first formwork 31 and the second formwork 32, the first formwork 31 and the height adjustment rod 33, and the height adjustment rod 33 and the fixing rod 34 are all detachably connected. Generally, bolts or pins are used. In this embodiment, bolts are used to secure the various components.

[0031] like Figure 5 As shown, the inner frame structure 1 and the adjustment plate 2 that have been fixed in advance are placed on the inclined floor 4, the first formwork 31 and the second formwork 32 are fixedly installed around the inner frame structure 1, the fixing rod 34 finds a position on the height adjustment rod 33 that matches the height of the upper surface of the inner frame structure 1 and is fixed to the inner frame structure 1, and concrete is poured into the inner frame structure 1 to form a concrete base 6. The use of concrete filling can increase the contact area between the base structure and the inclined floor 4, convert the line load into a surface load, increase the structural stability, and avoid damage to the surface layer of the inclined floor 4 during the erection of the support frame 5. Concrete can pass through the gap in the middle of the adjustment plate 2, and the pouring height of the concrete base 6 is not higher than the minimum height of the first formwork 31 and the second formwork 32 relative to the ground. Therefore, the first formwork 31 and the second formwork 32 block the concrete while also playing a shaping role. As shown Figure 6 As shown, after the concrete has dried, the components of the formwork structure 3 can be removed and stored for recycling, reducing construction costs. The formed concrete base 6 plays a good leveling role between the inclined floor 4 and the upper surface of the inner frame structure 1, while greatly enhancing the stability of the base structure.

[0032] like Figure 7As shown, after the formwork structure 3 is removed, a support frame 5 is installed on the upper surface of the inner frame structure 1. The support frame 5 is a standard section support frame and is fixedly connected to the upper surface of the inner frame structure 1. In this embodiment, the support frame 5 is fixedly connected to the inner frame structure 1 by bolts. In other embodiments, the support frame 5 and the inner frame structure 1 can also be fixed by welding or other methods.

[0033] The utility model also provides a method for using the support frame base structure for inclined floors:

[0034] The leveling plate 2, which has been pre-trimmed according to the slope of the inclined floor 4, is fixedly connected to the inner frame structure 1 and placed on the inclined floor 4, so that the leveling plate 2 contacts the inclined floor 4;

[0035] Sequentially fix the first template 31 and the second template 32 into a square structure surrounding the outer side of the inner frame 1, fix one end of the height adjustment rod 33 to the first template 31, and confirm the position of the fixing rod 34 according to the height of the inner frame structure 1 and fix it to the other end of the height adjustment rod 33;

[0036] Fill the internal frame structure 1 with concrete to cast the concrete base 6, with the concrete filling amount not exceeding the minimum height of the first formwork 31 and the second formwork 32 relative to the ground;

[0037] After the concrete base 6 is dry and formed, the formwork structure 3 is removed;

[0038] A support frame 5 is installed on the upper surface of the internal frame structure 1 .

[0039] The above-described embodiment is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Persons skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, any technical solution obtained by equivalent substitution or equivalent transformation falls within the scope of protection of the present invention.
