Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a concrete anti-slope hanging formwork reinforcement structure and a construction method. Background Art

[0002] At present, most projects use wooden formwork, composite support formwork or metal formwork for secondary formwork to complete the design requirements of the counter-slope structure. Concrete counter-slope is generally used to meet the functional requirements of the building. It is a treatment done when encountering an opening or edge to prevent rainwater from leaking in or to set a cover on the top (for example, indoor toilets, showers or kitchens require waterproof areas). The counter-slope is a concrete component with a certain thickness and height around the opening and connected to the surrounding concrete slabs. Counter-slope concrete is required on the ground or floor panels of kitchens, toilets, showers and floors with waterproofing requirements.

[0003] However, the current construction method still has drawbacks in actual use. When pouring, the existing concrete counter-step formwork is poured directly after the formwork is set. The formwork generally adopts a door-shaped clamp to clamp and fix the top of the formwork. During the pouring process, the concrete will impact the formwork on both sides. Since the force of the clamps on the formwork on both sides is not uniform, the formwork is prone to displacement when impacted by the concrete, resulting in an offset between the formed counter-step and the originally designed position. At the same time, due to the change in volume of the concrete after solidification, the formwork that is deformed by the impact of the concrete during pouring is easily damaged by squeezing the formwork during the concrete solidification process.

[0004] Therefore, the existing concrete anti-step formwork cannot meet the needs in actual use, so there is an urgent need for improved technology in the market to solve the above problems. Summary of the Invention

[0005] In order to improve the problem that the force applied by the clamps to the formwork is not uniform, which causes the formwork to be easily displaced when impacted by concrete, resulting in an offset between the formed counter-ridge and the originally designed position; at the same time, since the volume of the concrete changes after solidification, the formwork is deformed when impacted by concrete during pouring, and the formwork is easily damaged by squeezing during the concrete solidification process, the present invention provides a concrete counter-ridge hanging formwork reinforcement structure and a construction method.

[0032] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention.

[0033] The following is combined with Figure 1-2 The present invention is described in further detail.

[0034] The embodiment of the present invention provides a concrete anti-slope hanging formwork reinforcement structure and construction method. Figure 1 and Figure 2 The concrete anti-slope hanging formwork reinforcement structure includes a support formwork 1, a positioning bracket 2, and a reinforcement assembly 3. The support formwork 1 includes a support plate 11 and an inner support bracket 12. A steel skeleton is reserved between two adjacent sections of the wall or column at the anti-slope design location. The positioning bracket 2 is welded and fixed to the steel skeleton. In this embodiment, the inner support bracket 12 is a steel frame. The inner support bracket 12 is installed at the construction location according to the drawings. The two ends of the inner support bracket 12 are welded and fixed to the positioning bracket 2. Two support plates 11 are provided and are vertically installed on both sides of the inner support bracket 12.

[0035] Reference Figure 1 The reinforcement component 3 includes a fixing part 31, which has two vertically arranged card plates 311 and a crossbeam 312 for connecting the two card plates 311 together. The crossbeam 312 is located at the top of the two card plates 311. The fixing parts 31 are evenly arranged along the length direction of the two support plates 11. The two card plates 311 respectively contact the outer side surfaces of the two support plates 11, and the crossbeam 312 contacts the top of the two support plates 11, fixing the two support plates 11 on both sides of the inner support bracket 12.

[0036] In order to prevent the fixing member 31 from sliding and tilting on the support plate 11, a plurality of card grooves 111 are evenly and vertically arranged on the outer side surfaces of the two support plates 11. When installing the fixing member 31, the two card plates 311 of the fixing member 31 are inserted into the card grooves 111 to limit the position of the fixing member 31 and prevent the fixing member 31 from slipping or tipping over.

[0037] Reference Figure 1The reinforcement assembly 3 also includes a reinforcement member 32 and a fixing screw 33. The number of reinforcement members 32 is the same as the number of fixing members 31. The reinforcement member 32 includes a reinforcement plate 321 and a fastening plate 322. The fastening plate 322 is bent, and one end of the fastening plate 322 is bent and abuts against the middle position of the outer side surface of one of the support plates 11, and the other end extends horizontally and abuts against the beam 312, and extends out of the range of the support formwork 1. One end of the reinforcement plate 321 is set on the fastening plate 322, and the other end extends downward and abuts against the middle position of the outer side surface of the other support plate 11. The fixing screw 33 fixes the reinforcement plate 321 and the fastening plate 322 to the support plate 11.

[0038] Among them, in order to enable the reinforcement 32 to clamp the support plate 11 more tightly, in this embodiment, the reinforcement plate 321 and the fastening plate 322 are both made of elastic steel plates, and the bent part of the fastening plate 322 has an elastic force to squeeze inward, and the middle position of the reinforcement plate 321 is bent away from the support plate 11, so that the reinforcement plate 321 has an elastic force to squeeze in the direction of the support plate 11, and the reinforcement plate 321 and the fastening plate 322 are both squeezed in the direction of the support plate 11, so that the two support plates 11 are more firmly pressed against the inner support bracket 12, and the two support plates 11 can withstand greater impact force.

[0039] When the fixing plate 321 is in the fixed position, the fixing plate 321 is locked and the fixing plate 322 is locked.

[0040] In order to make the two support plates 11 more evenly subjected to the extrusion force of the reinforcement 32, a fixing plate 112 is fixed along the length direction of the two support plates 11 at the middle position of the outer side surfaces thereof, and the bottom ends of the reinforcement plate 321 and the fastening plate 322 are in contact with the fixing plate 112. The fixing plate 112 can distribute the extrusion force applied by the reinforcement 32 on the support plate 11 more evenly, so that the force applied to the support plate 11 is more even.
