Description

Technical Field

[0001] This invention relates to the field of precast building technology, and in particular to a vertical one-time forming production mold for precast ribbed base plates. Background Technology

[0002] Cast-in-place, prefabricated, and prefabricated monolithic floor slabs are the three most common types. Cast-in-place floor slabs offer advantages such as good integrity and high horizontal stiffness, but involve significant on-site wet work, large amounts of formwork, and serious on-site noise and environmental pollution. Compared to cast-in-place floor slabs, prefabricated floor slabs avoid many of the problems associated with cast-in-place construction, but their biggest drawback is poorer integrity and seismic resistance. Prefabricated monolithic floor slabs, also known as composite floor slabs, offer integrity and seismic resistance between cast-in-place and prefabricated floor slabs. Precast ribbed composite slabs are a type of composite floor slab, with a precast base slab composed of a reinforced concrete slab and concrete ribs on the slab. The ribs and holes on the ribs of the precast ribbed base slab significantly improve the rigidity of the base slab during construction, while also solving pipeline layout issues. Figure 6 As shown, the perforated ribs on the slab give the precast ribbed base slab good mechanical properties; however, they also make the fabrication of the precast ribbed base slab more complicated, requiring the formwork to be erected and the concrete ribs 23 to be poured a second time after the reinforced concrete slab 22 is poured. The complicated fabrication process is not conducive to the industrial production of precast ribbed base slabs and also hinders their widespread application. Summary of the Invention

[0003] In view of this, the present invention provides a vertical one-time forming production mold for prefabricated ribbed base plates, the main purpose of which is to reduce the production steps of prefabricated ribbed base plates and reduce labor costs.

[0004] To achieve the above objectives, the present invention mainly provides the following technical solutions:

[0005] This invention provides a vertical one-time forming production mold for prefabricated ribbed bottom plates, which includes: an upper cover plate, a lower cover plate, an intermediate support plate, an intermediate vertical plate, a bottom plate, and two side plates.

[0006] Each of the side plates includes a first side plate, a middle plate, and a second side plate that are fixedly connected in sequence, with the first side plate and the second side plate being parallel to each other;

[0007] The upper cover plate is connected to the outer edge of the first side plate by a detachable structure;

[0008] The lower cover plate is connected to the outer edge of the second side plate via a detachable structure;

[0009] The intermediate support plate is detachably connected to the inner edge of the second side plate, and the intermediate support plate is sequentially connected to the lower side of the intermediate plate, the inner edge of the first side plate, and the lower side of the first side plate.

[0010] The middle vertical plate is connected to the inner edge of the second side plate via a detachable structure, and the middle vertical plate is sequentially connected to the upper side of the middle plate and the inner edge of the first side plate.

[0011] The base plate is detachably connected to the lower side of the intermediate support plate and the lower side of the lower layer cover plate via a detachable structure.

[0012] The intermediate vertical plate has multiple first holes arranged axially on the surface of the intermediate plate, and the intermediate support plate has multiple second holes arranged axially on the surface of the intermediate plate. Each first hole corresponds to one of the second holes and is used to insert the rib hole mold.

[0013] The objectives of this invention and the technical problems it addresses can be further achieved by the following technical measures.

[0014] Optionally, a connecting rod is also included, with multiple rib-hole molds arranged sequentially on the axial side of the connecting rod, for simultaneously inserting the multiple rib-hole molds into the first hole and the second hole.

[0015] Optionally, the first side plate is evenly distributed with multiple first reserved longitudinal reinforcement holes.

[0016] Optionally, the second side plate has a plurality of second reserved longitudinal reinforcement holes evenly distributed thereon.

[0017] Optionally, the detachable structure is a detachable hinge.

[0018] By employing the above technical solution, the present invention has at least the following advantages:

[0019] After the mold is assembled, a first pouring gate is formed between the middle vertical plate and the upper cover plate (the width of the first pouring gate is equal to the width of the first side plate), and a second pouring gate is formed between the middle vertical plate and the lower cover plate (the width of the second pouring gate is equal to the width of the second side plate).

[0020] Then, multiple ribbed molds are passed through the first hole and the second hole in sequence.

[0021] Concrete is poured into the mold through the first and second pouring ports, so that the upper slab, lower slab and ribs are formed simultaneously. Since multiple rib hole molds are arranged sequentially along the axial direction of the mold, after the concrete is poured and cured, each rib hole mold is pulled out in sequence, each detachable structure is removed in sequence, and then each plate is removed in sequence for demolding.

[0022] Specifically, the advantages of this mold are as follows:

[0023] 1. A one-time casting mold for precast ribbed base plates is provided. The mold is easy to assemble and disassemble, has no technical threshold, and does not require secondary casting of the ribs. It can effectively reduce the production steps of precast ribbed base plates and reduce labor costs.

[0024] 2. Using vertical casting to produce precast base slabs greatly reduces the floor space occupied by a single production unit, improves the utilization efficiency of the work area, thereby increasing production efficiency, reducing production costs, and facilitating industrialized production.

[0025] 3. It is recyclable. The intermediate mold can be modified, customized and flexibly replaced according to different rib forms, so that it can be used to produce precast ribbed base plates with different rib forms. Attached Figure Description

Detailed Implementation

[0033] To further illustrate the technical means and effects adopted by the present invention to achieve the intended purpose, the specific embodiments, structures, features, and effects according to the present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments. In the following description, different "embodiments" or "embodiments" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0035] like Figure 1 , Figure 2 , Figure 4 As shown, an embodiment of the present invention provides a vertical one-time forming production mold for a prefabricated ribbed bottom plate, which includes: an upper cover plate 4, a lower cover plate 5, an intermediate support plate 6, an intermediate vertical plate 7, a bottom plate 8, and two side plates.

[0036] Each of the side plates includes a first side plate 1, a middle plate 2, and a second side plate 3 that are fixedly connected in sequence, with the first side plate 1 and the second side plate 3 being parallel to each other;

[0037] The upper cover plate 4 is connected to the outer edge of the first side plate 1 by a detachable structure;

[0038] The lower cover plate 5 is connected to the outer edge of the second side plate 3 by a detachable structure;

[0039] The intermediate support plate 6 is connected to the inner edge of the second side plate 3 by a detachable structure. The intermediate support plate 6 is sequentially connected to the lower side of the intermediate plate 2, the inner edge of the first side plate 1, and the lower side of the first side plate 1.

[0040] The middle vertical plate 7 is connected to the inner edge of the second side plate 3 by a detachable structure. The middle vertical plate 7 is sequentially connected to the upper side of the middle plate 2 and the inner edge of the first side plate 1.

[0041] The bottom plate 8 is detachably connected to the lower side of the intermediate support plate 6 and the lower side of the lower layer cover plate 5 via a detachable structure.

[0042] The intermediate vertical plate 7 has multiple first holes 9 arranged axially on the surface of the intermediate plate 2, and the intermediate support plate 6 has multiple second holes 10 arranged axially on the surface of the intermediate plate 2. Each first hole 9 corresponds to one of the second holes 10, which are used to insert the rib hole mold 11.

[0043] The working process of the vertical one-time forming production mold for prefabricated ribbed base plates is as follows:

[0044] After the mold is assembled, a first pouring port is formed between the middle vertical plate 7 and the upper cover plate 4 (the width of the first pouring port is equal to the width of the first side plate 1, and the length of the first pouring port is equal to the distance between the two side plates), and a second pouring port is formed between the middle vertical plate 7 and the lower cover plate 5 (the width of the second pouring port is equal to the width of the second side plate 3, and the length of the second pouring port is equal to the distance between the two side plates).

[0045] Then, the multiple ribbed molds 11 are passed through the first hole 9 and the second hole 10 in sequence.

[0046] Concrete is poured into the mold through the first and second pouring ports, so that the upper plate, lower plate and plate ribs are formed simultaneously. Since multiple rib hole molds 11 are arranged sequentially along the axial direction of the mold, after the concrete is poured and cured, each rib hole mold 11 is pulled out in sequence, each detachable structure is removed in sequence, and then each plate is removed in sequence for demolding.

[0047] In the technical solution of the present invention, the upper concrete slab, concrete ribs and lower concrete slab are poured simultaneously, which avoids the cumbersome manufacturing process, reduces the production links of the precast ribbed bottom slab 8, is conducive to the industrial production of the precast ribbed bottom slab 8, and is conducive to its widespread application.

[0048] Specifically, to facilitate demolding, a release agent can be brushed on the inside of the mold in the early stage. During the demolding process, first remove the rib mold 11, then remove the cover plate and side plate, and then rotate the precast base plate 8 and the mold so that the lower plate is placed on the ground. Remove the base plate 8, the middle vertical plate 7 and the middle support plate 6 respectively to complete the demolding of the precast base plate 8.

[0049] like Figure 3 As shown, in a specific embodiment, a connecting rod 12 is also included, and a plurality of rib hole molds 11 are arranged sequentially on the axial side of the connecting rod 12 for synchronously inserting the plurality of rib hole molds 11 into the first hole 9 and the second hole 10.

[0050] In this embodiment, specifically, the operator can hold the connecting rod 12 and simultaneously align multiple rib hole molds 11 with the first hole 9 and the second hole 10, avoiding the need to insert and remove the rib hole molds 11 one by one, thus avoiding tedious and inefficient repetitive work.

[0051] like Figure 1 As shown in the specific embodiment, the first side plate 1 is evenly distributed with a plurality of first reserved longitudinal rib holes 13.

[0052] In this embodiment, specifically, two first side plates 1 are arranged opposite each other at both ends of the mold, and the first reserved longitudinal reinforcement holes 13 are opposite each other. The steel bars are passed through the two first reserved longitudinal reinforcement holes 13 in sequence. The length of the steel bars is greater than the distance between the two first side plates 1 so that the tensioning machine can tension the steel bars. The purpose of tensioning is to straighten the steel bars and reduce the deflection caused by the weight of the steel bars themselves. When the precast base plate 8 is a prestressed base plate 8, the steel bars can be replaced with prestressed steel bars and tensioned to apply prestress.

[0053] like Figure 1 As shown in the specific embodiment, the second side plate 3 is evenly distributed with a plurality of second reserved longitudinal reinforcement holes 14.

[0054] In this embodiment, specifically, two second side plates 3 are positioned opposite each other at both ends of the mold, and the second reserved longitudinal reinforcement holes 14 are positioned opposite each other. Reinforcing bars are sequentially passed through the two reserved longitudinal reinforcement holes 14, with the length of the reinforcing bars being greater than the distance between the two second side plates 3, so that the tensioning machine can tension the reinforcing bars. The purpose of tensioning is to straighten the reinforcing bars and reduce deflection caused by their own weight. When the precast base plate 8 is a prestressed base plate 8, the reinforcing bars can be replaced with prestressed reinforcing bars and tensioned to apply prestress.

[0055] like Figure 5 As shown, in a specific embodiment, the detachable structure is a detachable hinge.

[0056] In this embodiment, the detachable hinge specifically includes a sub-hinge plate 15, a female hinge plate 16, and pins. The sub-hinge plate 15 and the female hinge plate 16 are respectively fixedly connected to adjacent plate components. The pins include a first pin 17 and a second pin 18. The sub-hinge plate 15 is fixedly connected to a insertion tube 19. The first pin 17 and the second pin 18 are slidably connected to opposite ends of the insertion tube 19. A spring 21 is located inside the insertion tube 19 and is used to abut the first pin 17 and the second pin 18. The female hinge plate 16 is fixedly connected to two end tubes 20 and is used to accommodate the exposed portions of the first pin 17 and the second pin 18. When it is necessary to disassemble the hinge, the pushing force of the spring 21 is manually overcome, and the first pin 17 and the second pin 18 are simultaneously pushed into the insertion tube 19, thereby separating the sub-hinge plate 15 and the female hinge plate 16, and thus separating the various plate components.

[0057] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
