Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a large-angle inclined concrete bottom plate template system. Background Art

[0002] The foundation slab is a building structure that bears the compression, pulling, shearing and other loads of the building superstructure. In the existing technology, the foundation slab is generally set horizontally. However, with the rapid development and construction of cities, more and more buildings are gradually developing in the direction of three-dimensional space, and the construction of various underground projects is also increasing. In some industrial buildings, it is necessary to set a concrete foundation slab inclined along the slope on a slope with a large angle as the basis of a connecting passage connecting the underground space with the ground space. The connecting passage is used to install transportation equipment, personnel passage or installation of cables and other facilities; the angle of the slope can reach 30° to 60°, and the height can reach more than 10 meters, which brings challenges to the construction of the concrete slab. In the existing technology, two methods are usually used to construct the slab at the large angle bevel part. One method is to first construct a plum blossom-type ground anchor rod, then manually pile up a concrete cushion layer, then tie the steel bars, connect the top and side molds of the bottom plate fixed by the tie rods, and pour concrete; the other method is to first install a plum blossom-type ground anchor rod, then spray the concrete cushion layer, then tie the steel bars, connect the top and side molds of the bottom plate fixed by the tie rods, and pour concrete. Both of the above methods require the installation of dense anchors that penetrate deep into the slope soil. Due to the large slope gradient and area, it is difficult for workers to maintain stability when performing anchor construction on the slope, which increases the difficulty of operation, resulting in slow construction progress and the inability to guarantee construction quality and safety. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a large-angle inclined concrete floor template system, which solves the problems of complex construction process, slow construction progress, and difficulty in ensuring construction quality and construction safety of large-angle inclined concrete floors.

[0004] The technical solution adopted by the utility model is:

[0005] A large-angle inclined concrete bottom plate formwork system is used for the bottom plate construction of the original soil part of the slope, comprising: a bottom plate, including a fixed plate that fits the original soil of the slope and has the same size as the slope surface of the original soil; a support block, which is arranged at the bottom of the slope surface and abuts against the bottom plate; and a top plate, which is arranged parallel to the top of the bottom plate and connected to the bottom plate by a screw.

[0006] Furthermore, the screw is a two-stage water-stop screw, one end of which is a fixed end fixed to the fixed plate; the other end is a connecting end, which vertically passes through the top mold and fixes the top mold between the conical nut and the mountain-shaped clamp.

[0007] Furthermore, the bottom formwork also includes vertical ribs, reinforcing diagonal ribs, longitudinal steel bars and transverse steel bars; the vertical ribs are vertically arranged on the fixed plate, and the reinforcing diagonal ribs connect the top of the vertical ribs with the fixed plate; the longitudinal steel bars are parallel to the fixed plate and connected to the top of the vertical ribs; the transverse steel bars are vertically connected to the longitudinal steel bars.

[0008] Furthermore, the height of the vertical rib is less than the thickness of the bottom plate minus the thickness of the protective layer.

[0009] Furthermore, the screw rods are evenly arranged on the fixing plate.

[0010] Furthermore, one end surface of the support block is perpendicular to the fixing plate.

[0011] Furthermore, it also includes side molds, which are arranged at the ends of the bottom mold and the top mold and are connected with the bottom mold and the top mold to form a whole.

[0012] Furthermore, the fixing plate is a thin steel plate, and the top formwork is a wooden formwork.

[0013] The advantages and positive effects of the utility model are:

[0015] 2. The bottom formwork is installed in an integral manner, which is easy and quick to operate and improves construction efficiency;

[0016] 3. By setting vertical reinforcement, strengthening diagonal reinforcement, longitudinal reinforcement and transverse reinforcement, the reinforcement binding operation is reduced and the construction efficiency is further improved;

[0017] 4. By setting fixed plates, vertical ribs, reinforced diagonal ribs, longitudinal reinforcements and transverse reinforcements, the bottom formwork and the bottom plate are connected as a whole, so that the bottom plate has better strength and performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Example 1

[0034] The utility model provides a large-angle inclined concrete bottom plate formwork system, which is used for the bottom plate construction of the original soil part of the slope, such as Figure 1 As shown, in this embodiment, the bottom plate 8 is arranged along the slope surface of the sloped original soil 1, and the top of the bottom plate 8 is designed as a connecting channel 5 for connecting the above-ground space 6 and the underground space 7.

[0035] like Figure 2-Figure 4 As shown, a large-angle inclined concrete base plate formwork system includes a bottom formwork 2, a support block 3 and a top formwork 4, wherein the bottom formwork 2 includes a fixed plate 201 that is attached to the original soil 1 on the slope and has the same size as the slope surface of the original soil 1, and the bottom of the fixed plate 201 is attached to the slope surface of the original soil 1 on the slope; the support block 3 is arranged at the bottom of the slope surface of the original soil 1 on the slope, and abuts against the bottom formwork 2 to prevent the bottom formwork 2 from sliding down along the slope surface; the top formwork 4 is arranged parallel to the top of the bottom formwork 2 and is connected to the bottom formwork 2 by a screw rod 202, and the screw rod 202 connects the bottom formwork 2 and the top formwork 4 to form a whole, which serves as a formwork for casting the base plate 8, and is fixed to the slope under the friction between the bottom formwork 2 and the original soil 1 on the slope and the support of the support block 3. It can be understood that the distance between the bottom formwork 2 and the top formwork 4 is the thickness of the base plate 8.

[0036] In this embodiment, one side of the bottom of the slope surface of the original slope soil 1 is an underground space 7, which has been constructed in advance, and a space is reserved between the bottom of the slope surface and the underground space 7 for accommodating the bottom plate 8. The support block 3 is arranged in the reserved space and fixed to the ground or soil below; preferably, the support block 3 is constructed together with the structure of the underground space 7 and is connected to the underground space 7 as a whole.

[0037] In a preferred embodiment, the support block 3 is arranged along the width direction of the slope surface of the slope original soil 1, which is the same as the width of the bottom mold 2. One end face of the support block 3 is perpendicular to the fixed plate 201, so that the bottom mold 2 is more stable; in some other embodiments of the utility model, the support block 3 is a block structure dispersedly arranged along the width direction of the slope surface of the slope original soil 1.

[0038] In the prior art, anchor rods are usually densely installed on the slope surface of the original soil 1 of the slope, followed by cushion construction, and finally the top formwork 4 is connected by anchor rods to realize the template support of the bottom plate 8. This method requires multiple construction processes at the slope. Due to the large slope angle, it is difficult for workers to stand during construction, which has an adverse effect on the construction quality and safety. Compared with the bottom formwork 8 template in the prior art, the bottom formwork 2 in this embodiment is made according to the slope surface size of the slope, installed on the slope surface as a whole, and fixed by the support block 3, which simplifies the process of template construction, can ensure construction quality and construction safety, and greatly improve construction efficiency.

[0039] In this embodiment, the screw 202 can connect the bottom mold 2 and the top mold 4, and can also provide support for the top mold 4 to fix the top mold 4 above the bottom mold 2; specifically, the top mold screw 202 is a two-stage water-stop screw, including a fixed end 2021 and a connecting end 2023, and the fixed end 2021 and the connecting end 2023 are respectively threadedly connected to the conical nut 2022 to form a whole screw 202; wherein the fixed end 2021 is fixed to the fixed plate 201; the connecting end 2023 vertically passes through the top mold 4, and fixes the top mold 4 between the conical nut 2022 and the mountain-shaped clamp (not shown); it should be noted that the mountain-shaped clamp is a commonly used component in the template construction process in this field, and the conical nut 2022 and the mountain-shaped clamp are both threadedly connected to the connecting end 2023, so that the inner side of the top mold 4 is in conflict with the conical nut 2022, and the outer side of the top mold 4 is in conflict with the mountain-shaped clamp, and the top mold 4 can be clamped by rotating the mountain-shaped clamp, and finally the top mold 4 is made more stable.

[0040] Preferably, in order to further enhance the stability of the top form 4, there are multiple screws 202 evenly arranged on the fixed plate 201, so that each part of the top form 4 is subjected to balanced force, ensuring that it is not easy to move and deform during the process of template erection and concrete pouring.

[0041] The bottom formwork includes a fixed plate 201 and vertical ribs 203, reinforced diagonal ribs 204, longitudinal steel bars 205 and transverse steel bars 206; the vertical ribs 203 are vertically arranged on the fixed plate 201, and the reinforced diagonal ribs 204 connect the top of the vertical ribs 203 and the fixed plate 201, which can effectively improve the bending resistance of the vertical ribs 203; the longitudinal steel bars 205 are arranged along the inclination direction of the slope, parallel to the fixed plate 201, and connected to the top of the vertical ribs 203, which can be spliced, welded or riveted, among which welding is preferred; the transverse steel bars 206 are vertically connected to the longitudinal steel bars 205, which can be connected by welding, riveting or binding, preferably welding. The fixed plate 201 and the vertical ribs 203, the reinforced diagonal ribs 204, the longitudinal steel bars 205 and the transverse steel bars 206 are connected to form a whole, which on the one hand enhances the rigidity of the fixed plate 201 and makes the bottom mold 2 have better stability; on the other hand, structural steel bars are arranged inside the bottom plate 8, and by arranging the vertical ribs 203, the reinforced diagonal ribs 204, the longitudinal steel bars 205 and the transverse steel bars 206, at least part of the structural steel bars are replaced, thereby saving the subsequent steel bar binding process.

[0042] It is understandable that the height of the vertical rib 203 should not be too high. Even if the vertical rib 203, the reinforced diagonal rib 204, the longitudinal steel bar 205 and the transverse steel bar 206 can completely replace the structural steel bars, sufficient protective layer thickness should be reserved to prevent the steel bar corrosion from affecting the service life of the base plate 8; therefore, the height of the vertical rib 203 is less than the thickness of the base plate 8 minus the thickness of the protective layer; the thickness of the protective layer is set according to the design requirements.

[0043] According to the requirements of pouring the base plate 8, the present embodiment also includes a side form (not shown), which is arranged at the ends of the base form 2 and the top form 4, and is connected to the base form 2 and the top form 4 to form a whole, and the cavity inside it is used for pouring concrete of the base plate 8; specifically, the relative side forms are fixed by tension bolts.

Wooden planks and steel pipes are commonly used components in formwork construction, which will not be elaborated here.
