Description

Technical Field

[0001] The invention relates to the technical field of interior decoration, and in particular to a clean laboratory suspended ceiling conversion layer system and a construction method thereof. Background Art

[0002] The clean laboratory has a high floor height and the length of the hanger is greater than 2.5m. There are many pipelines installed on the upper part and the layout is complicated. The ceiling needs to be set up with a conversion layer. The ceiling conversion system is located in the clean laboratory area and has high requirements for cleanliness. The conventional ceiling conversion layer system generally uses steel to make a conversion layer, and the hangers are welded on the conversion layer according to the standard spacing. On this basis, the following ceiling keels and panels are installed. This method is relatively convenient to construct when the space is high and can meet the requirements of the ceiling structure, but the cost of construction materials is relatively high, and the welding work of the steel must take protective measures for the installation pipelines, which will increase the construction cost. In order to ensure the stability of the conversion layer, there must be diagonal braces that are reliably connected to the structural beam side and the wall side, and they are set up in both the vertical and horizontal directions. The installation pipelines need to be avoided, and the construction is difficult. Summary of the invention

[0003] In order to solve the technical problems existing in the prior art, the present invention provides an interior decoration technology and a construction method thereof.

[0004] To achieve the above object, the technical solution of the present invention is as follows:

[0005] A clean laboratory ceiling conversion layer system comprises a vertical structure, a horizontal structure, a building floor and a building wall. The vertical structure comprises a hanger, which is fixedly connected to the building floor through expansion bolts, the horizontal structure is fixedly connected to the building wall through angle steel and through bolts, and the vertical structure is fixedly connected to the horizontal structure through bolts.

[0006] As a preferred technical solution, the outer shell of the boom is provided with a thick-walled galvanized steel pipe.

[0007] As a preferred technical solution, the hanger rod and the thick-walled galvanized steel pipe are an integrated structure.

[0008] As a preferred technical solution, the horizontal structure includes transverse U-shaped channel steel and longitudinal U-shaped channel steel.

[0009] As a preferred technical solution, the construction method of the clean laboratory ceiling conversion layer system includes the following steps:

[0010] Step 1: confirm the location of the boom according to the on-site installation pipeline layout;

[0011] Step 2: On-site line laying;

[0012] Step 3: Locate the fixed point positions on the building floor and building wall according to the layout;

[0013] Step 4: Punch holes at the fixing points of the building wall panels, and place angle steel and through bolts for temporary fixing;

[0014] Step 5: Place the vertical structure and fix the hanger on the building floor with expansion bolts;

[0015] Step 6: Fix the horizontal structure and the suspension rod by bolts;

[0016] Step seven: Fix the horizontal structure to the building wall panel using through bolts and angle steels.

[0017] As a preferred technical solution, in step 2, on-site layout includes: laying out the hanger layout positions on the building floor, and laying out the elevations of the transverse U-shaped channel steels and the longitudinal U-shaped channel steels on the building wall panels.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The clean laboratory ceiling conversion layer system of the present invention has a vertical structure with a thick-walled galvanized steel pipe as the outer cover of the hanger. The galvanized steel pipe has a light weight, is pressure-bearing, corrosion-resistant, and has strong deformation resistance. The force system composed of the hanger and the galvanized steel pipe can replace the steel structure and can be customized by the factory without the need for on-site secondary processing. The material cost is low and the construction cost is low. The connection between the structures adopts a non-welding connection form to avoid the impact of welding operations on the installation of pipelines. The horizontal structure is fixed to the building wall panel with angle steel fixings and expansion bolts. The building wall panel provides horizontal support, and there is no need to set diagonal braces. The construction impact is small and the construction material cost is low.

[0024] The technical solution of the present invention is further described below in conjunction with specific implementation methods:

[0025] like Figure 1As shown, a clean laboratory ceiling transfer layer system includes a vertical structure 1, a horizontal structure, a building floor 7 and a building wall 4. The vertical structure 1 uses a thick-walled galvanized steel pipe with a hanger. The galvanized steel pipe has a light weight, is pressure-bearing, corrosion-resistant and has strong deformation resistance. The hanger and the thick-walled galvanized steel pipe are an integrated structure. The force system composed of the hanger and the thick-walled galvanized steel pipe can replace the steel structure and can be customized by the factory without the need for on-site secondary processing. Figure 3 As shown, the hanger rod is fixedly connected to the building floor 7 via expansion bolts 7 .

[0026] The horizontal structure includes transverse U-shaped channel steel 2 and longitudinal U-shaped channel steel 3. Figure 2 As shown, the horizontal structure is fixedly connected to the building wall panel 4 by angle steel 5 and through bolts 6. The building wall panel 4 provides horizontal support, and there is no need to set diagonal supports, which has little impact on construction.

[0027] The vertical structure 1 is fixedly connected to the horizontal structure by bolts.

[0028] The connections between system structures are not welded to avoid the impact of welding operations on the installed pipelines.

[0029] The construction method of the clean laboratory ceiling conversion layer system includes the following steps:

[0030] Step 1: confirm the location of the boom according to the on-site installation pipeline layout;

[0031] Step 2: On-site layout, specifically, laying out the hanger arrangement position on the ground of the building floor 7, and laying out the elevations of the horizontal U-shaped channel steel 2 and the longitudinal U-shaped channel steel 3 on the building wall panel 4;

[0032] Step 3, locating the fixed point positions on the building floor 7 and the building wall 4 according to the setting line;

[0033] Step 4: Punch holes at the fixing points of the building wall panels 4, and place angle steels 5 and through bolts 6 for temporary fixing;

[0034] Specifically, one side of the angle steel 5 is attached to the building wall panel 4, and the through bolt 6 is passed through the holes on the fixing points of the angle steel 5 and the building wall panel 4. The through bolt 6 passes through the entire building wall panel 4 and is fixed with a nut.

[0035] Step 5, placing the vertical structure 1, i.e., the thick-walled galvanized steel pipe is covered on the hanger rod, and the hanger rod is fixed on the building floor 7 by expansion bolts 7;

[0036] Step 6: Fix the horizontal structure and the suspension rod by bolts;

[0037] Step seven, fix the horizontal structure to the building wall panel 4 by through bolts 6 and angle steel 5, fit the other side of angle steel 5 to U-shaped channel steel, and fix it with through bolts 6, so that the horizontal structure is fixed to the building wall panel 4.
