Technical Field
[0001] This utility model belongs to the technical field of a hollow inner mold metal mesh cement partition wall mesh frame, and particularly relates to a hollow inner mold metal mesh cement partition wall mesh frame. Background Technology
[0002] Hollow core metal mesh cement partition walls are widely used in existing buildings. These partition walls typically employ a mesh frame fixed to the floor and roof, with mortar applied to the exterior. This design offers advantages such as light weight, good sound insulation, heat insulation, fire resistance, and earthquake resistance, while also saving mortar. One existing mesh frame for hollow core metal mesh cement partition walls comprises two opposing wavy mesh panels. The troughs of the two mesh panels are joined together, and the crests face each other, forming a cavity between the crests. Vertical ribs are installed within this cavity, and binding holes are spaced vertically on these ribs for securing them to the mesh panels. Due to its structure, this type of hollow internal mold metal mesh cement partition wall has the following defects: First, it has poor impact resistance. When constructing the hollow internal mold metal mesh cement partition wall, the upper and lower keels are only fixed to the roof and ground with nail guns, which has a poor fixing effect. In the event of an impact, the nails are easy to fall off, reducing the overall impact resistance of the wall. Second, it has poor seismic resistance. In the event of an earthquake, the ground and roof will be misaligned, causing the hollow internal mold metal mesh cement partition wall to break or collapse. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a hollow inner mold metal mesh cement partition wall mesh frame with good impact resistance, good seismic resistance and long service life.
[0004] To solve the above problems, the technical solution of the hollow inner mold metal mesh cement partition wall frame of this utility model is as follows: it includes two opposing wavy mesh sheets, the troughs of the two mesh sheets are attached together, the crests of the two mesh sheets are opposite each other, and a cavity is formed between the crests of the two mesh sheets. A vertical keel is set in the cavity, and the vertical keel is tied and fixed to the mesh sheet. A vertical support frame is set at the trough position of the two mesh sheets, and the vertical support frame is fixed to the mesh sheet. The vertical support frame includes a support vertical rod, and multiple horizontal rods are fixed on the support vertical rod. The length of the horizontal rod is greater than the distance between two adjacent crests, and the two ends of the horizontal rod are fixed to the crests on both sides of the corresponding trough of the horizontal rod.
[0005] Its additional technical features are: The length of overlap between the two ends of the crossbar and the crest of the mesh is greater than or equal to 2cm; Vertical support frames are provided on both sides of each trough position, and the two vertical support frames are fixedly connected. A vertical support frame is provided on one side of each trough position, and the vertical support frames are arranged at intervals on both sides of the mesh. The vertical support frame is positioned at intervals of one or more troughs.
[0006] Compared with the prior art, the hollow inner mold metal mesh cement partition wall frame provided by this utility model has the following advantages: First, it includes two opposing wavy mesh sheets, with the troughs of the two mesh sheets fitting together and the crests of the two mesh sheets facing each other, forming a cavity between the crests of the two mesh sheets. A vertical keel is set in the cavity, and the vertical keel is tied and fixed to the mesh sheet. A vertical support frame is set at the trough position of the two mesh sheets, and the vertical support frame is fixed to the mesh sheet. The vertical support frame includes a support vertical rod, and multiple horizontal rods are fixed on the support vertical rod. The length of the horizontal rod is greater than the distance between two adjacent crests, and the two ends of the horizontal rod are fixed to the crests on both sides of the corresponding trough.
[0007] According to the design requirements for the hollow internal formwork metal mesh cement partition wall, lines are manually laid out above the floor and below the roof. The lower keel is then fixed at the marked lines above the floor, and the upper keel is fixed at the marked lines below the roof. Two opposing wavy mesh panels are spot-welded together, with their troughs touching and their crests facing each other. Vertical keels are inserted into the cavities between the crests of the two mesh panels and tied to them or fixed with U-shaped nails. The wire mesh and vertical keels are cut according to the height and width of the hollow internal formwork metal mesh cement partition wall. The cut mesh panels are then erected so that they stand upright on the roof. Between the keel and the lower keel; tie the erected mesh panels and the upper and lower sides of the vertical keel to the upper and lower keels respectively, and tie the joints of the two sets of adjacent mesh panels to the upper and lower keels; according to the design requirements, place conduits at the troughs where the mesh panels fit; according to the design, drill anchor holes above the floor at the troughs where the mesh panels fit, and drill anchor holes below the roof at the corresponding positions of the upper anchor holes. Insert upper anchor bars with anchoring adhesive into the upper anchor holes, and insert lower anchor bars with anchoring adhesive into the lower anchor holes. The length of the upper and lower anchor bars protruding from the floor and roof should be ≥20cm; fix the upper end of the vertical support frame to the upper anchor bars, and fix the lower end of the vertical support frame to the upper anchor bars. The lower rebar is fixed; an inner mortar layer is applied to the outer side of the troughs of the two mesh panels by spraying or manual application, with the outer surface of the inner mortar layer roughly flush with the plane where the crests of the two mesh panels are located; after the inner mortar layer at the troughs of the two mesh panels has solidified, an outer mortar layer is applied to the entire outer side of the mesh panel by manual application, with the thickness of the outer mortar layer ≥2.5cm, maintaining the flatness of the outer surface of the outer mortar layer; the upper and lower rebars are connected by vertical support frames, with a vertical support frame set at intervals, greatly improving the wall's impact resistance and seismic performance; secondly, because the two ends of the crossbar overlap with the crests of the mesh panels... The length of the vertical support frame is greater than or equal to 2cm, which prevents the horizontal bar from coming off the mesh at the crest during construction. Thirdly, since the vertical support frame is set at intervals of one or more troughs, it saves material costs for walls with low earthquake and impact resistance requirements, depending on design and seismic performance needs. Fourthly, the presence of vertical support frames on one side of each trough, and their spaced arrangement on both sides of the mesh, improves the wall's impact and earthquake resistance. Fifthly, the fixed connection between the two vertical support frames on both sides of each trough further enhances the wall's earthquake resistance. Attached Figure Description

Detailed Implementation
[0009] The structure and operating principle of a hollow inner mold metal mesh cement partition wall according to this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0010] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The diagram shows a structural schematic of a hollow internal mold metal mesh cement partition wall according to this utility model. The hollow internal mold metal mesh cement partition wall includes opposing wavy mesh sheets 1 and 2. The troughs 3 of the two mesh sheets are joined together, and the crests 4 of the two mesh sheets are opposite each other, forming a cavity 5 between the crests 4. A vertical keel 6 is installed within the cavity, and the vertical keel 6 is tied and fixed to the mesh sheets or fixed with "U"-shaped nails. A vertical support frame 7 is installed at the troughs 3 of the two mesh sheets, and the vertical support frame 7 is fixed to the mesh sheets. The vertical support frame 7 includes a supporting vertical rod 71, and multiple horizontal rods 72 are fixed on the supporting vertical rod 71. The length of the horizontal rods 72 is greater than that of two adjacent wavy rods. The distance of peak 4, the two ends of the horizontal bar 72 are fixed to the peaks on both sides of the corresponding trough of the horizontal bar 72. According to the design requirements of a mesh frame for a hollow inner mold metal mesh cement partition wall, lines are manually laid above the floor and below the roof. Then, the lower keel is fixed at the line position above the floor, and the upper keel is fixed at the line position below the roof. The two opposite wavy mesh pieces have their troughs 3 attached together and their peaks 4 facing each other. The mesh pieces are spot welded together using a welding machine. Vertical keels 6 are inserted into the cavity between the peaks of the two mesh pieces and tied to the mesh pieces or fixed with "U"-shaped nails. According to the height and width of the hollow inner mold metal mesh cement partition wall, the wire mesh and vertical keels are connected. Cut the ribs; erect the cut mesh panels so that they stand between the upper and lower keels; tie and fix the erected mesh panels and the upper and lower sides of the vertical keel 6 to the upper and lower keels respectively, and tie and fix the connection points of the two sets of adjacent mesh panels; according to the design requirements, place conduits at the troughs where the mesh panels fit; according to the settings, drill anchor holes above the floor at the troughs where the mesh panels fit, and drill anchor holes below the roof at the corresponding positions of the upper anchor holes; insert upper anchor bars with anchor adhesive into the upper anchor holes, and insert lower anchor bars with anchor adhesive into the lower anchor holes, with the length of the upper and lower anchor bars protruding from the floor and roof ≥ 20cm; connect the upper end of the vertical support frame to the upper anchor bars. Fix the lower end of the vertical support frame to the lower rebar; apply mortar layer 8 to the outer side of the trough of the two mesh panels by spraying or manual application, with the outer surface of the mortar roughly flush with the plane where the crests of the two mesh panels are located; after the mortar at the trough of the two mesh panels has solidified, apply mortar to the entire outer side of the mesh panel by manual application, with the thickness of the mortar layer 9 on the mesh panel surface ≥2.5cm, and maintain the flatness of the applied mortar. The upper and lower rebars are connected together by the vertical support frame, and a vertical support frame is set at intervals. In this way, the vertical support frame and the mesh panel are integrated, making processing more convenient and greatly improving the impact resistance and seismic performance of the wall.
[0011] The overlap length between the two ends of the crossbar 72 and the crest of the mesh 5 is greater than or equal to 2cm, which prevents the crossbar from coming out of the mesh at the crest during construction.
[0012] like Figure 1 As shown, a vertical support frame 7 is provided on one side of each trough 3 position, and the vertical support frames 7 are arranged at intervals on both sides of the mesh, which further improves the seismic performance of the wall.
[0013] like Figure 4 As shown, the vertical support frame 7 is set at a distance of one or more troughs 3. For some walls with low requirements for earthquake resistance and impact resistance, the material cost of the vertical support frame is saved according to the design and earthquake performance requirements.
[0014] like Figure 5 As shown, vertical support frames 7 are installed on both sides of each trough 3 position, and the two vertical support frames 7 are fixedly connected, which further improves the seismic performance of the wall.
[0015] The scope of protection of this utility model is not limited to the above embodiments. Any structure that is the same as or similar to the mesh frame structure of the hollow inner mold metal mesh cement partition wall of this utility model falls within the scope of protection of this utility model.
