Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to a reinforcement device for fair-faced concrete wall construction. Background Art

[0002] The secondary structure is constructed after the primary structure is completed. It is relative to the load-bearing structure and is a non-load-bearing structure. The fair-faced concrete secondary structure wall refers to a concrete secondary structure wall that directly uses the natural texture after concrete forming as the finishing effect. In seismic areas, it is usually necessary to set expansion joints at the parts where both sides of the wall are connected to the load-bearing columns to relieve the stress of the building during the seismic wave process, reduce the damage degree of the structure, and ultimately improve the seismic performance of the building.

[0003] Before constructing the fair-faced concrete secondary structure wall between two load-bearing columns, it is usually necessary to first install and fix the formwork, and then carry out the pouring construction of the wall. At present, for the construction of the secondary structure wall with expansion joints, generally, a shaped formwork with expansion joints is directly formed by splicing and fixing between the formworks. There are generally quality problems such as difficult reinforcement of the formwork at the expansion joint, easy misalignment of the formwork, and poor forming quality of the expansion joint. For fair-faced concrete walls, it cannot meet the quality requirements.

[0004] The prior art such as the document with the authorization announcement number of CN220848689U discloses a shaping device for fair-faced concrete secondary structure wall construction, including two groups of load-bearing columns and a formwork assembly arranged between the two groups of load-bearing columns. The formwork assembly includes Formwork I, Formwork II, and expansion joint strips respectively fixed at both ends in the length direction of Formwork I. The expansion joint strip is an integrally formed part, and a connecting piece is arranged at Formwork II for connecting Formwork II with the load-bearing column.

[0005] The working principle of the above structure is as follows: First, complete the connection of the expansion joint strip and the connecting piece with the load-bearing column respectively, then fix Formwork I and Formwork II respectively through the expansion joint strip and the connecting piece, and then pour the fair-faced concrete secondary structure wall. Finally, remove the two formworks, expansion joint strip, and connecting piece respectively.

[0006] However, the device still has the following problems: The expansion joint strip and the connecting piece need to be aligned during installation, otherwise the installation of the two formworks is prone to misalignment, affecting the forming of the structural wall; at the same time, when removing the components, especially when removing the expansion joint strip, it is easy to cause damage to the structural wall. Summary of the Utility Model

[0007] In view of the above problems, the purpose of the present utility model is to provide a reinforcement device for fair-faced concrete wall construction. By setting the first formwork, the second formwork and two positioning components, the purpose of pouring the secondary concrete wall is achieved. And a single positioning component in this device can position and fix the two formworks on the same side, avoiding the misalignment problem caused by the separate positioning and installation of the two formworks. At the same time, the positioning component is embedded at the connection between the load-bearing column and the wall after the concrete pouring is completed, greatly strengthening the connection strength between the two, and having the advantages of simple construction and accurate positioning.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0028] A reinforcement device for fair-faced concrete wall construction provided by the present utility model is arranged between two load-bearing columns a, and includes two relatively arranged first templates 1 and second templates 2, and two positioning components 3 respectively installed on the two load-bearing columns a; both ends of the positioning component 3 are respectively connected to the first template 1 and the second template 2.

[0029] In this embodiment, the positioning component 3 includes a bottom plate 301, mounting holes 302 provided on the bottom plate 301, connecting bolts 303 passing through the mounting holes 302 and connected to the load-bearing column a, a first folding plate 304 provided at one end of the bottom plate 301 and connected to the first template 1, and a second folding plate 305 provided at the other end of the bottom plate 301 and connected to the second template 2.

[0030] In this embodiment, the bottom plate 301 is a strip-shaped plate, and the number of the mounting holes 302 and the connecting bolts 303 is multiple and they correspond one by one. It is worth noting that the first folding plate 304 and the second folding plate 305 can be strip-shaped plates the same as the bottom plate 301, or can be multiple plate bodies distributed at a certain interval on the bottom plate 301. Further preferably, in order to ensure the structural strength of the positioning component, the bottom plate 301, the first folding plate 304 and the second folding plate 305 are formed by integral bending.

[0031] In this embodiment, the first folding plate 304 has a flange 304a with an opening facing the load-bearing column a. The first folding plate 304 further includes a folding edge 304b provided at the end of the flange 304a and connected to the surface of the first template 1, and a first connection hole 304c provided on the folding edge 304b. Among them, the flange 304a is preferably a right-angle flange, and the folding edge 304c is parallel to the bottom edge of the flange 304a.

[0032] In this embodiment, the second folding plate 305 includes a right-angle plate 305a connected to the end of the bottom plate 301 and opening towards the load-bearing column a, a folding plate 305b disposed at the end of the right-angle plate 305a and connected to the surface of the second template 2, and a second connection hole 305c disposed on the folding plate 305b; perfusion holes 305d are provided on both the right-angle plate 305a and the folding plate 305b, and the second folding plate 305 further includes a resisting plate 305e disposed at the end of the folding plate 305b and connected to the surface of the load-bearing column a. Among them, the folding plate 305b is parallel to the bottom edge of the right-angle plate 305a, and the setting of the resisting plate 305e is used to enhance the connection strength between the second folding plate 305 and the load-bearing column a.

[0034] The working principle of the reinforcement device provided in this embodiment is as follows:

[0035] The two positioning components 3 are installed on the two load-bearing columns a through connection bolts 303. The connection bolts 303 protrude from the bottom plate 301 to serve the role of embedded steel bars, strengthening the connection strength between the secondary structure wall after pouring and the original load-bearing column a.

[0036] The first template 1 and the second template 2 are respectively connected to the two positioning components 3 at both ends through the first bolt 304d and the second bolt 305f. After the first template 1 and the second template 2 are installed, the two templates and the two load-bearing columns a are connected to form a closed cavity for pouring the secondary structure wall, and the two positioning components 3 are located at the connection between the template and the load-bearing column a.

[0037] After the template installation is completed, concrete is poured. At this time, the concrete fills the formed closed cavity. The first folding plate 304 promotes the formation of a separation joint, and the space between the second folding plate 305 and the load-bearing column a is filled with concrete through the perfusion holes 305d. Finally, the two templates are removed after the secondary structure wall is formed. The positioning component 3 is built in at the connection between the formed secondary structure wall and the load-bearing column a, thereby greatly improving the structural strength of the connection.

[0038] The reinforcement device provided in this embodiment has the following advantages compared with the existing devices: First, one positioning component can position and fix two templates on the same side, avoiding the dislocation problem caused by the separate positioning and installation of the two templates. Second, the positioning component is embedded at the connection between the load-bearing column and the wall after the concrete pouring is completed, greatly enhancing the connection strength between the two. Third, the second folding plate structure in the positioning component forms a cavity for filling concrete again, which, in cooperation with the connecting bolts, enhances the connection strength between the positioning component and the load-bearing column, avoiding the problem of cracks appearing between the positioning component and the load-bearing column after the secondary structure wall is poured.

[0039] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the art to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar ways to substitute them, but they will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
