Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a tongue-and-groove formwork construction device. Background Art

[0002] A construction joint is the joint formed between the first and last concrete pours during the concrete pouring process, when the concrete is poured in sections due to design or construction needs. A construction joint is not a physical "joint"; it simply forms a bond between the first concrete pour and the next concrete pour, created when the initial setting time has expired.

[0003] In the existing construction method, the construction joint of the concrete slab is vertically continuous. If the construction joint treatment process is slightly improper during actual on-site construction, if there is water accumulation on the slab surface, it will easily leak along the gap, which can easily cause leakage and cracking in the construction joint of the concrete slab, resulting in poor construction molding quality.

[0004] Therefore, in response to the above technical problems, how to improve the construction quality of concrete slab construction joints is a technical problem that technical personnel in this field need to solve. Utility Model Content

[0005] The purpose of this application is to provide a tongue-and-groove formwork construction device, which makes the construction joint of the concrete slab into a tongue-and-groove shape, effectively reducing the quality risks of leakage and cracking at the construction joint of the concrete slab and improving the construction quality.

[0006] To achieve the above-mentioned purpose, the present application provides a tongue-and-groove formwork construction device, comprising:

[0007] A positioning plate is placed on the bottom surface of the template;

[0008] A side mold is vertically and fixedly arranged above the positioning plate;

[0009] Tongue-and-groove timbers are fixed perpendicularly to the side forms and are arranged parallel to the positioning plates, so that the vertical construction joint of the concrete slab forms two staggered vertical sections at the tongue-and-groove timbers and the side forms;

[0010] The locking square timber is located above the tongue-and-groove square timber and is fixedly connected thereto.

[0011] Preferably, a reinforcing square timber is provided on the end surface of the side formwork away from the tongue-and-groove square timber, one end surface of the reinforcing square timber is in contact with the side formwork, and the other end surface is in contact with the positioning plate;

[0012] A supporting connecting plate is provided on the outside of the reinforcing square timber, and a plurality of iron nails are provided on the supporting connecting plate. A part of the iron nails are inserted into the reinforcing square timber and then inserted into the side form, and another part of the iron nails are inserted into the reinforcing square timber and then inserted into the positioning plate, so as to reinforce the connection effect between the positioning plate and the side form.

[0013] Preferably, the supporting connecting plate is arranged obliquely, and the iron nails on the supporting connecting plate are inserted obliquely into the reinforcing square timber.

[0014] Preferably, one side surface of the tongue-and-groove square timber is fitted with a side surface of the side form, and the tongue-and-groove square timber is fixed to the side form by nails.

[0015] Preferably, the locking square timber is arranged parallel to the tongue-and-groove square timber, and the locking square timber is fixed to the tongue-and-groove square timber by nails.

[0016] Preferably, steel bars are inserted between the locking square timber and the tongue-and-groove square timber, and steel bars are also inserted between the side formwork and the positioning plate.

[0017] Preferably, concrete is poured in the formwork to form a reinforced concrete slab having two staggered vertical sections.

[0018] Compared with the above-mentioned background technology, the present application uses tongue-and-groove square timber to form two staggered vertical sections at the construction joint of the concrete slab, that is, one vertical section is formed by the tongue-and-groove square timber, and the other vertical end face is formed by the side form. The two vertical sections are not on the same vertical plane, thereby effectively slowing down or even blocking the infiltration of accumulated water along the construction joint, reducing the risk of leakage of the concrete slab, and improving the construction quality.

[0019] Specifically, the present application includes a positioning plate, a side form, a tongue-and-groove square timber and a locking square timber. The positioning plate is fixed on the bottom surface of the column formwork, and plays a basic positioning role to ensure the accuracy of the position of the device. The side formwork is vertically and fixedly arranged on the upper side of the positioning plate. The tongue-and-groove square timber is vertically fixed to the side formwork and is arranged parallel to the positioning plate. Since the tongue-and-groove square timber itself has a certain thickness and protrudes on one side of the side formwork, a vertical section different from the side formwork will be formed at the tongue-and-groove square timber on the original vertical construction joint of the concrete slab, thereby forming two staggered vertical sections. Compared with the traditional vertical through-construction joint, the two staggered vertical sections can obviously reduce the penetration effect, thereby avoiding leakage, cracking and other problems in the construction joint of the concrete slab.

[0024] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] It should be noted that in this embodiment, the directions or positional relationships indicated by "upper," "lower," "front," and "back" are based on the directions or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this application and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction. Therefore, they should not be construed as limitations on this application. Furthermore, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0027] like Figure 1 and Figure 2 As shown, in this embodiment, a tongue-and-groove formwork construction device is provided. The device includes a positioning plate 1, side forms 2, tongue-and-groove square timbers 3, and lock-joint square timbers 4. The positioning plate 1 is located on the bottom surface of the formwork 7 and serves as a basic positioning function to ensure the accuracy of the device's installation position. The side forms 2 are vertically and fixedly mounted above the positioning plate 1 and have flat side surfaces on both sides.

[0028] The tongue-and-groove timber 3 is located on the side of the side form 2 facing away from the positioning plate 1 and is fixed perpendicularly to the side of the side form 2. On this basis, the tongue-and-groove timber 3 is arranged parallel to the positioning plate 1. Because the tongue-and-groove timber 3 has a certain thickness and protrudes from one side of the side form 2, it will form a vertical cross-section different from that of the side form 2 at the tongue-and-groove timber 3 on the original vertical construction joint of the concrete slab, thus forming two staggered vertical cross-sections.

[0029] In other words, due to the protruding effect of the tongue and groove square timber 3, the vertical construction joint of the concrete slab forms two staggered vertical sections at the tongue and groove square timber 3 and the side formwork 2.

[0030] The locking square timber 4 is located above the tongue and groove square timber 3 and is fixedly connected thereto, thus playing a certain reinforcing role.

[0031] Based on the above embodiments, the present application utilizes the tongue-and-groove square timber 3 to form two staggered vertical sections at the construction joint of the concrete slab, that is, one vertical section is formed by the tongue-and-groove square timber 3, and the other vertical end face is formed by the side form 2. The two vertical sections are not on the same vertical plane, thereby effectively slowing down or even blocking the infiltration of accumulated water along the construction joint, reducing the risk of leakage of the concrete slab, and improving the construction quality.

[0032] In addition, in order to further improve the stability of the side form 2, in this application, a reinforcing square wood 5 is provided on the end surface of the side form 2 away from the tongue and groove square wood 3, please refer to Figure 1 or Figure 2 One end face of the reinforcing square timber 5 is in contact with the side mould 2, and the other end face is in contact with the positioning plate 1, thereby playing a certain supporting role.

[0033] On this basis, a supporting connecting plate 6 is provided on the outside of the reinforcing square timber 5. Please refer to Figure 2 A plurality of iron nails are provided on the supporting connecting plate 6. Some of the iron nails are inserted into the reinforcing square timber 5 and then inserted into the side form 2, while the other part of the iron nails are inserted into the reinforcing square timber 5 and then inserted into the positioning plate 1, thereby strengthening the connection effect between the positioning plate 1 and the side form 2 and ensuring the stability of the side form 2 setting.

[0034] It should be noted that the supporting connecting plate 6 of the present application is inclined, and the inclination here is relative to the reinforcing square wood 5, and the iron nails on the supporting connecting plate are inserted obliquely into the reinforcing square wood 5. Compared with the vertical insertion method, the oblique insertion of the iron nails has a better fixing effect and a stronger bearing capacity.

[0035] Similarly, one side of the tongue-and-groove square timber 3 is also fitted with the side of the side form 2 to ensure the fit between the two and improve relative stability, and the tongue-and-groove square timber 3 is fixed to the side form 2 by nails.

[0036] The locking square wood 4 is arranged parallel to the tongue-and-groove square wood 3 and is also fixed to the tongue-and-groove square wood 3 by nails. It should be noted that the above-mentioned nail fixing methods include but are not limited to this method, which will not be described in detail here. It is sufficient to ensure good connection stability between the relative components.

[0037] Please refer to Figure 2 Rebars 8 are inserted between the interlocking timbers 4 and the tongue-and-groove timbers 3, and between the side forms 2 and the positioning plate 1. Of course, the provision of the rebars 8 does not affect the overall arrangement of the device, and holes can be opened at the corresponding positions for the rebars 8 to pass through. When concrete is poured in the formwork 7, two rebar 8 concrete slabs with staggered vertical sections can be formed at the tongue-and-groove timbers 3 and the side forms 2.

[0038] For the above components, in-depth design and prefabrication can be carried out according to actual needs; similarly, their thickness, material, size, model specifications can be selected according to actual needs, and no excessive restrictions will be imposed here.

[0039] Compared with traditional construction devices, this application is simple, fast, efficient, low-cost to manufacture, firmly fixed, not prone to displacement, reduces the risk of concrete slab leakage, and improves construction quality.

[0040] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0041] This document uses specific examples to illustrate the principles and implementation methods of this application. The description of the above examples is only intended to help understand the method and core ideas of this application. It should be noted that for those skilled in the art, without departing from the principles of this application, various improvements and modifications can be made to this application, and such improvements and modifications also fall within the scope of protection of the claims of this application.
