Description

Technical Field

[0001] This invention relates to the field of building construction, and in particular to a method for installing cross-grids. Background Technology

[0002] like Figure 1 As shown, some decorative structures are designed on the exterior of the glass curtain wall 3 of some buildings 1, such as crisscrossing rods to form a grille 2 shape. However, the rods of the grille 2 are inclined, and if the installation angle is not accurate, the rods of the grille 2 will not be parallel, resulting in rework. Therefore, this poses a challenge to the hoisting and installation of the rods of the grille 2. Summary of the Invention

[0003] The purpose of this invention is to provide a method for installing cross-grids, addressing the problem that some existing buildings have grid-shaped exterior glass curtain walls with inclined grid members, requiring high parallelism in the installation of the members.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A method for installing a cross grille includes the following steps: S1. In the installation area of ​​the building, lay out the horizontal control lines, grid center lines, and intersection angle control lines for the grille installation, mark all connection points between the grille and the building, and check the outer frame edge lines of the grille. S2. Drill holes at the connection points between the grille and the building, install post-installed anchor bolts for the post-installed embedded parts in the drilled holes, connect the post-installed anchor bolts to the corresponding pre-embedded steel plates, and adjust the pre-embedded surfaces to be on the same plane; plugs are connected to the pre-embedded steel plates at the top and bottom of the installation area. S3. Connect the pre-embedded steel plates on the beams in the installation area to the corresponding angle brackets and level them. S4. Lay all the grid members flat on the ground. The grid members include first-direction members and second-direction members. The first-direction members are installed along the entire length, while the second-direction members are installed in segments. First, arrange all the first-direction members, and then arrange the second-direction members between adjacent first-direction members. Check the intersection gaps and the overlap length of the members. Spray a number on each member according to the left-right installation order and mark the intersection opening points. Set up the connection structure at the intersection opening points. The connection structure includes angle steel, first screws, and second screws. First, connect the angle steel to the corresponding position of the first-direction member with the first screws and hoist it together with the first-direction member. S5. According to the ground number, hoist the first direction member. The two ends of the first direction member are connected to the plug for positioning, and the plug extends into the first direction member. The corner bracket is connected to the middle of the first direction member. Arrange the first direction members one by one along the horizontal control line, control the spacing and straightness of the first direction members. The screws at both ends of the first direction member are temporarily fixed. The connection between the middle section and the corner bracket is not tightened at all, leaving a margin for cross-interlacing. S6. Hoist the second-direction member. Connect the corresponding angle steel at both ends of the second-direction member with the second screw. Do not tighten it completely to form a cross grid. Ensure that the gaps in the entire grid are uniform, the cross angles are consistent, and there is no misalignment or extrusion deformation. After the interlacing is completed, make minor adjustments to the overall flatness and grid spacing. S7. Tighten all end and cross node screws or nuts in a consistent sequence from the middle of the first member to both ends.

[0006] The present invention employs a method for installing cross-grids. First, the connection points between the grid and the building are determined by laying out lines. Then, post-installed embedded parts are set at the connection points as the installation foundation to ensure a stable connection between the grid and the building. Next, the connection form of the first-direction members is determined by inserting end plugs into the grid members and connecting the first-direction members with the middle angle brackets. The second-direction members are connected based on the first-direction members. The connection positions of the first and second-direction members are determined by pre-assembling and numbering the grid on the ground, and a pre-set connection structure is used to connect them. First, the first-direction members are hoisted according to the ground numbers. After the first-direction members are inserted into the plugs, they are temporarily fixed with screws, but the angle bracket connections are not tightened. Then, the second-direction members are hoisted and connected to the angle steel with second screws, but not fully tightened. After adjusting parameters such as gaps, angles, misalignments, and compression deformation of the first and second-direction members, the entire area of ​​nodes is finally tightened to complete the installation of the grid on the building.

[0025] In related technologies, some buildings have a grid-like design on the exterior of their glass curtain walls. The grid's members are angled, posing a significant challenge to the parallelism of the members during installation. This leads to the technical solution presented in this application, which is described below in conjunction with... Figures 1 to 9 To elaborate.

[0026] Example 1 like Figures 1 to 9 As shown, the installation method of the cross grille according to the present invention includes the following steps: Step 1: Measurement and layout like Figure 1 and Figure 3As shown, in the installation area 11 of building 1, use a laser level to mark the horizontal control lines, grid center lines, and bidirectional cross angle control lines for the installation of grille 2, mark all connection points between grille 2 and building 1, check the outer frame edge lines of grille 2, and verify the squareness of the diagonal lines.

[0027] Step 2: Drill holes and install / fix the first rear-mounted part 4 and the second rear-mounted part 6. like Figures 4 to 6 , Figure 9 As shown, the first post-embedded component 4 includes a first pre-embedded steel plate 41, a plug 42 and a first post-embedded anchor bolt 43. The plug 42 is welded to the first pre-embedded steel plate 41, and the first pre-embedded steel plate 41 and the first post-embedded anchor bolt 43 are connected by a nut.

[0028] like Figure 4 , Figure 7 and Figure 8 As shown, the second post-embedded part 6 includes a second pre-embedded steel plate 61, an angle bracket 62, a second post-embedded anchor bolt 63, and a bolt 64. The second pre-embedded steel plate 61 and the second post-embedded anchor bolt 63 are connected by nuts. The angle bracket 62 is attached to the second pre-embedded steel plate 61 and is connected to the second post-embedded anchor bolt 63 by nuts. The angle bracket 62 and the bolt 64 are connected by nuts.

[0029] like Figures 4 to 9 As shown, use an electric hammer to drill vertical holes at the top and bottom of the installation area 11 and on the beam 12 that runs through the installation area 11, according to the marked points. Clean the dust and debris in the holes (it must be blown clean to prevent the anchor bolts from failing under stress). Insert the first post-installed anchor bolt 41 into the holes at the top and bottom of the installation area 11, and insert the second post-installed anchor bolt 63 into the holes on the beam 12. Let it stand and wait for the agent to fully cure. After curing, install the first pre-embedded steel plate 41 corresponding to the first post-installed anchor bolt 41, and install the second pre-embedded steel plate 61 corresponding to the second post-installed anchor bolt 63. Fine-tune the positions of the first pre-embedded steel plate 41 and the second pre-embedded steel plate 61 to ensure that all pre-embedded surfaces are on the same plane. Both the first pre-embedded steel plate 41 and the second pre-embedded steel plate 61 are galvanized pre-embedded steel plates.

[0030] Step 3: Install and level the corner bracket 62 like Figure 4 , Figure 7 and Figure 8 As shown, the corner bracket 62 is connected to the second rear anchor bolt 63 by a nut to fix it on the second embedded steel plate 61, and leveled piece by piece according to the horizontal control line; the in-and-out dimensions of the corner bracket 62 are uniformly reserved with an adjustment margin of 15mm, and the nuts of all corner brackets 62 connected to the second embedded steel plate 61 are initially tightened but not finally tightened to avoid batch deviation.

[0031] Step 4: Pre-assemble and number the grating 2 on the ground. like Figure 3As shown, all grid 2 members are laid flat in the hard paved area. According to the first and second directions designed, the grid 2 members include first-direction members 21 and second-direction members 22. All first-direction members 21 are arranged according to the first direction, and all second-direction members 22 are arranged according to the second direction. The first-direction members 21 are installed along their full length, while the second-direction members 22 are installed in segments. First, all first-direction members 21 are arranged, and then second-direction members 22 are arranged between adjacent first-direction members 21. The intersection gaps and member overlap lengths are checked. Each member is sprayed with a number according to the left-right installation sequence, the intersection opening points are marked, and the cutting burrs on the members are corrected. Figure 6 and Figure 8 As shown, a connecting structure 5 is provided at the hole where the first directional member 21 connects to the second directional member 22. The connecting structure 5 includes an angle steel 51, a first screw 52, ​​and a second screw 53. First, the angle steel 51 is connected to the corresponding position of the first directional member 21 through the first screw 52, ​​and then hoisted together with the first directional member 21. In some optional embodiments, the first direction and the second direction are arranged perpendicularly, that is, the first directional member 21 and the second directional member 22 are arranged perpendicular to each other.

[0032] Step 5: Fix the first member 21 at high altitude like Figures 4 to 6 , Figure 9 As shown, according to the ground numbering, the first directional member 21 is hoisted, and both ends of the first directional member 21 are inserted and positioned into the plug 42 of the first rear embedded part 4, with the plug 42 extending into the first directional member 21; as shown Figure 7 and Figure 8 As shown, a sleeve rod 23 is provided in the position of the first directional rod 21 corresponding to the corner bracket 62. The bolt 64 passes through the sleeve rod 23, the first directional rod 21, and the corner bracket 62 in sequence and is then connected to the nut. The first directional rods 21 are arranged one by one along the horizontal control line to control the spacing and straightness of the first directional rods 21. The screws at both ends of the first directional rods 21 are temporarily fixed, and the connection between the middle section and the corner bracket 62 is not tightened at all, leaving a margin for cross-interpenetration.

[0033] Step 6: Second-direction member 22 is inserted, aligned, and fixed. like Figure 3 As shown, the second directional member 22 is hoisted, and its two ends are connected to the fixed first directional member 21, forming a standard intersecting grid; as shown. Figure 6 and Figure 8 As shown, align the pre-reserved holes one by one, and connect the second direction member 22 with the angle steel 51 already installed on the first direction member 21 through the second screw 53. Do not tighten completely to ensure that the gaps in the whole grid are uniform, the intersection angles are consistent, and there is no misalignment or extrusion deformation. After the interlacing is completed, make minor adjustments to the flatness of the body and the grid spacing.

[0034] Step 7: Final tightening of all joints and gap finishing Tighten all end and cross node screws or nuts in a consistent order from the middle of the first member 21 to both ends; check for height misalignment of the members of the grid 2 and use a rubber hammer to fine-tune and level them; cut off the excess members and grind the cut edges to ensure that the outer frame edge of the grid 2 is straight.

[0035] Step 8: Finishing and cleaning, protecting the finished product Neutral weather-resistant sealant is evenly applied to the gaps between the grille 2 and the wall and ceiling of building 1, and the sealant is pressed into the gaps smoothly without any breaks; the protective film on the surface of the grille 2 is removed, and fingerprints and dust are wiped off; anti-collision corner guards are affixed to the corners of the grille 2.

[0036] The installation method of the cross-grid described in this embodiment involves determining the connection points between the grid 2 and the building 1 by laying out lines, and then setting up post-installed embedded parts at the connection points as the installation foundation to ensure a stable connection between the grid 2 and the building 1. The connection form of the first directional member 21 is then determined by inserting the end plugs 42 into the grid 2 members and connecting the middle corner brackets 62 to the first directional member 21. The second directional member 22 is then connected based on the first directional member 21. The first directional member 21 is determined through ground pre-assembly and numbering of the grid 2. The connection positions of the first and second direction members 21 and 22 are determined, and the connection structure 5 is preset to connect the two. First, the first direction member 21 is hoisted according to the ground number. After the first direction member 21 is plugged into the plug 42, it is temporarily fixed by screws. The angle bracket 62 is not tightened at the connection. Then, the second direction member 22 is hoisted and the angle steel 51 is connected by the second screw 53 without final tightening. After adjusting the parameters such as the gap, angle, misalignment, and extrusion deformation of the first and second direction members 21 and 22, the final tightening of all nodes is carried out to complete the installation of the grid 2 on the building 1.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
