Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The external wall template structure and the construction method thereof solve the problem that the conventional wood template needs to be dismantled, and have simple and convenient construction. The external wall template structure can be used as a part of structural layer of a building after construction is completed, and can also be used as a decorative layer, so that the economical efficiency is good. The exterior wall formwork structure and the construction method thereof according to the present invention will be described with reference to the accompanying drawings.
As shown in fig. 1 to 5, the exterior wall formwork structure of an embodiment includes a plurality of prefabricated panels 1, each prefabricated panel 1 includes a prefabricated panel main body 10, reinforcing bars 12, connecting members 14, and fixing holes, the reinforcing bars 12 are cast in the prefabricated panel main body 10, the connecting members 14 are disposed in the prefabricated panel main body 10 and are used for being connected with the reinforcing bars 12 of an exterior wall, and the fixing holes are opened in the prefabricated panel main body 10 and penetrate through the prefabricated panel main body 10.
When the external wall template structure is used, the precast slab 1 is formed by sizing manufacturing in a manufacturer or on site, and the internal reinforcing steel bars 12 are fixed with the external wall reinforcing steel bars 12 through the connecting pieces 14. The prefabricated slab 1 is adopted to replace the traditional template, does not need to be dismantled after concrete pouring, can be directly used as a structural layer and a decorative layer of a building, saves a large amount of manual machines, and keeps better site appearance. In addition, the template is fixed through the fixing holes, so that the template supporting process is simplified, and the construction period is saved.
When the prefabricated panel 1 is manufactured, the reinforcing bars 12 are internally provided so that the reinforcing bars 12 can be cast in the prefabricated panel main body 10. In this embodiment, the reinforcing bars 12 are bidirectional reinforcing bars, which improves the strength of the prefabricated panel 1. In order to facilitate the fixing of the precast slab 1, a connecting member 14 is arranged on the inner side of the precast slab main body 10, and is bound and fixed with the outer wall steel bar 12 through the connecting member 14, so that the connection between the precast slab 1 and the outer wall is realized. Wherein the connecting member 14 may be a lifting ring or a lifting hook, etc. It will be understood that the number of the connecting members 14 can be selected according to the actual construction requirements, and in general, the more the number of the connecting members 14, the more stable the connection of the prefabricated panel 1 to the exterior wall. In order to facilitate mass production and assembly of the prefabricated panels 1, the prefabricated panels 1 are rectangular in shape in this embodiment. In other embodiments, the preformed sheet may have other shapes, such as diamond, triangle, etc.
The fixing holes are for facilitating penetration of the fixing member to fix the prefabricated panels 1 against lateral pressure of the concrete. The conventional external wall formwork needs the main edge, the secondary edge and the split bolt to be fixed so as to resist the lateral pressure of concrete and avoid the phenomenon of mold explosion. As shown in fig. 3, in this embodiment, the exterior wall formwork structure further includes an anchor plate 20 and a tie bolt 30, and the tie bolt 30 passes through the anchor plate 20 and the fixing hole in turn, thereby fixing the prefabricated panel 1 to the exterior wall structure. Since the precast slab 1 is a concrete precast slab and can resist a certain pressure, the lateral pressure of the concrete can be resisted by only arranging the backing plate 20 and the split bolt 30, and the formwork supporting process is greatly simplified. The shape and size of the shim plate 20 may be selected according to the actual situation, wherein the size of the shim plate 20 is larger than the size of the fixation hole. In the present embodiment, the backing plate 20 is a rectangular steel plate. During construction, holes may be punched in the backing plate 20 in advance to facilitate penetration of the tie bolts 30. The connection between the split bolt 30 and the outer wall 2 (or the ground wall) is realized by a connection method commonly used in the art, and the detailed description is omitted.
In this embodiment, the number of the fixing holes is plural, and the density of the fixing holes below the prefabricated panel 1 is greater than that of the fixing holes above the prefabricated panel 1. And taking the horizontal bisector of the precast slab 1 as a boundary, wherein the part above the bisector is the upper part of the precast slab 1, and the part below the bisector is the lower part of the precast slab 1. Since the lateral pressure generated by the concrete pouring varies with the height, the lateral pressure applied to the bottom of the prefabricated panel 1 is relatively the largest, and thus the number of the fixing holes is large, and it is convenient to arrange a plurality of tie plates 20 and tie bolts 30, thereby maximally using the tie bolts 30 and tie plates 20 to resist the lateral pressure generated when the concrete is poured. The shape and size of the fixing hole may be selected according to actual conditions, and the shape of the fixing hole matches the shape of the split bolt 30. In the present embodiment, the fixing hole is circular in shape.
In addition, before construction, whether the outer wall formwork structure can bear the lateral pressure of the concrete needs to be rechecked, and if only the counter bolts 30 and the backing plates 20 are adopted and cannot bear the lateral pressure of the concrete, a transverse main ridge can be additionally arranged on the precast slab 1 to prevent the occurrence of a mold explosion phenomenon. In addition, the prefabricated panels 1 should be as thin as possible to facilitate installation. Meanwhile, the length of the precast slab 1 is not too large, and the height of the one-time concrete pouring is not too high, so that the phenomenon of mold explosion caused by too large side pressure of the concrete is avoided.
Generally, a plurality of prefabricated panels 1 are provided according to the size of the exterior wall structure. As shown in fig. 1, in the present embodiment, opposite ends of the prefabricated panel main body 10 are provided with tongues and grooves 100. The two prefabricated panels 1 can be effectively connected by the tongue-and-groove 100. The tongue-and-groove 100 means that when two prefabricated plates 1 are connected, the adjacent side edges respectively form a half-edge through groove opening, so that the two prefabricated plates 1 can be conveniently overlapped and spliced up and down, thereby preventing a through seam and avoiding slurry leakage.
After the precast slabs 1 are hoisted to the preset positions, before concrete is poured, in order to prevent the concrete from generating a slurry explosion phenomenon, single-sided glue can be pasted between two adjacent precast slabs 1. Specifically, a single-sided adhesive is adhered to a gap between two precast slabs 1 to prevent the slurry leakage phenomenon, and then concrete is poured. The single-sided adhesive can be selected from the single-sided adhesives commonly used in the art, and is not limited herein.
In addition, as shown in fig. 4 and 5, in the process of erecting the external wall formwork in the basement, there may be a situation that the surrounding purlin 3 is arranged above the formwork, and in this situation, the pouring of concrete is not convenient. In this embodiment, one end of the prefabricated panel 1 is provided with a casting notch 40. When concrete is poured, a dustpan opening can be arranged on the pouring notch 40 so as to facilitate the pouring of the concrete. The shape and size of the casting notch 40 may be selected according to actual needs, and is not limited herein.
During construction, the prefabricated slab 1 needs to be hoisted to a preset position. As shown in fig. 1, in this embodiment, the external wall form structure further includes a bolt sleeve 50, and the bolt sleeve 50 is embedded in the precast slab main body 10 and connected to the reinforcing bars 12. In the manufacturing process of the prefabricated panel 1, the bolt sleeves 50 are pre-embedded in the prefabricated panel 1 and connected with the steel bars 12 inside the prefabricated panel 1. The bolt sleeves 50 can facilitate the installation of the hanging rings on the prefabricated panels 1 to facilitate the hoisting of the prefabricated panels 1. It will be appreciated that the end of the bolt housing 50 may be maintained flush with the end of the prefabricated panels 1 so that the disposition of the bolt housing 50 does not interfere with the coupling between the prefabricated panels 1.
The construction method of the above-described external wall formwork structure will be explained below.
The construction method of the external wall template structure of the embodiment comprises the following steps:

In this embodiment, a hanging ring is arranged on one side of the prefabricated slab 1 close to the outer wall. The prefabricated slab 1 is bound and fixed with the external wall steel bar 12 through a hanging ring. In addition, a bolt sleeve 50 is embedded in the prefabricated slab 1, and the bolt sleeve 50 is connected with the steel bar 12 in the prefabricated slab 1. The prefabricated panels 1 can be conveniently hoisted by the bolt sleeves 50.
The prefabricated panel 1 is fixed through the fixing holes. The backing plate 20 is disposed above the fixing holes, and the split bolts 30 are sequentially passed through the backing plate 20 and the fixing holes to connect the prefabricated panel 1 with the exterior wall 2 (i.e., the floor wall).
And pouring concrete to complete the construction of the external wall template structure. After the poured concrete reaches a certain strength, only the backing plate 20 and the split bolts 30 need to be removed, and the precast slab 1 does not need to be removed. The backing plate 20 and the counter bolts 30 can be recycled and turned over to the next supporting of the external wall formwork of the prefabricated slab 1.
Since the exterior wall structure requires installation of a plurality of prefabricated panels 1, in this embodiment, before pouring concrete, the method further includes: and single-sided adhesive is adhered to the gap between the adjacent prefabricated panels 1. The single-sided adhesive can prevent the concrete from leaking.
In addition, in this embodiment, before the step of binding the external wall reinforcing bars 12, the method further includes: after the construction of the underground structure bottom plate or the floor slab is completed, a waterproof blanket is constructed between the ground wall and the outer wall. After the waterproof construction is finished, the external wall steel bars 12 are bound, and then the prefabricated slab 1 is hoisted.
