Description

Technical Field

[0001] The utility model belongs to the field of prefabricated steel structure design and construction, and in particular relates to a prefabricated wall sealing node suitable for the reconstruction of multi-story industrial plants. Background Art

[0002] Most of the multi-storey industrial plants that have been built use reinforced concrete frame structures. In particular, heavy industrial enterprises have a large number of multi-storey reinforced concrete frames. Due to the weak environmental awareness of the people in the early days, these industrial plants were mostly open structures when they were put into production. Walls were not considered, and railings were used to surround the building floors. There are certain dust emissions during production, and there may also be some other low-risk pollution sources.

[0003] With the continuous advancement of the country's industrialization process, the impact and damage to the ecological environment are becoming increasingly severe, the public and the country's awareness of environmental protection is gradually strengthened, and the sewage treatment of existing factory buildings has become an urgent problem to be solved. The wall enclosure sealing transformation of existing open-type multi-story factory buildings has become the key construction content of the old factory renovation.

[0004] The general traditional solution is to use metal corrugated steel plates (hereinafter referred to as color plates) as the main wall material, and use C-shaped purlins as the color plate support structure. The construction process is roughly as follows: first, set post-embedded parts next to the original concrete columns and weld purlin supports on the embedded parts; set wind-resistant column embedded parts at the edge of the floor slab on the top surface of the frame beam of the wall-sealed renovation floor, and set corresponding wind-resistant column embedded parts at the bottom of the frame beam on the upper floor of the wall-sealed renovation floor; hoist the wind-resistant column to the installation position, weld the bottom to the embedded parts at the bottom of the frame beam, and connect the upper part to the embedded parts of the frame beam by bolts, and set purlin supports at the position where purlins need to be set; hoist the C-shaped purlins to the installation position, and connect the C-shaped purlins to the purlin supports by bolts; finally, fix the color plate and the color plate support structure together by self-tapping screws. The overall layout diagram is shown in the attached figure. Figure 1 shown.

[0005] This construction method has the following problems:

[0006] The construction speed is slow and the efficiency is low. When installing the purlins, each purlin needs to be hoisted to the installation position and bolted separately. Each purlin also needs to be equipped with two or more purlin brackets. The workload of on-site bolt connection and welding is large, there are many control points, the construction speed is slow, the construction period is long, and the efficiency is low.

[0007] The construction accuracy is low and the finished effect is poor. Due to the large number of embedded parts and the order of magnitude difference between the construction accuracy of the concrete structure and the steel structure, the original concrete itself may not be in the same plane. After the purlin support is installed, it is difficult to ensure that the purlins are in the same plane when they are installed. When the color plate is finally installed, there will be gaps in the overlap of the color plate, which will cause the risk of light leakage and dust leakage. In addition, there will be uneven areas on the surface of the color plate, which will affect the overall aesthetic effect.

[0008] The construction cost is high and the economic benefits are poor. There are many purlin support nodes, the welding workload is large, the steel consumption is large, and the material cost is high. There are many post-embedded parts, and the construction period of embedded parts is long. There are many nodes, and each purlin needs to be hoisted separately, which takes a long time to hoist and construct, and the rental cost of installation equipment is high.

[0009] Post-embedded parts are not good for concrete structures and pose a safety hazard. Columns, as the main vertical load-bearing components of the structure, play an extremely critical role in the stress of the structure. Generally, there are a large number of vertical steel bars in concrete columns. When post-embedded parts are constructed on the original concrete columns, the anchor bars of the embedded parts can easily hit the steel bars in the columns, and in extreme cases, the original steel bars in the columns may be broken. Post-embedded parts on beams are set at the top of the beams. There are a large number of load-bearing steel bars at the supports on the top of the beams, which are also easy to collide with the post-embedded steel bars, affecting the overall safety of the structure.

[0030] Beneficial effects of the utility model:

[0031] The utility model prefabricated wall node adopts the prefabricated structure and takes measures to make the color plate support structure in the reconstruction wall construction to be assembled and installed quickly and accurately. While meeting the basic use functions and safety reserves, it has the following advantages:

[0032] 1. High degree of assembly, fast construction speed and short construction period. The utility model prefabricated wall node sets a component for fixing the wind-resistant column on the side of the frame beam, so that the purlins and wind-resistant columns that originally required single hoisting construction can be made into a whole in advance in the factory, so that the original complex and cumbersome construction process of the wall renovation is changed into an assembly construction process, which greatly reduces the work of on-site hoisting and welding, greatly increases the construction speed and shortens the construction period of on-site construction.

[0033] 2. High construction accuracy and good finishing effect. By setting the upper baffle and leveling layer in advance, it is ensured that the position of the node can reach the preset design accuracy, so that the color plate support structure can be installed quickly and accurately with high accuracy. The existence of the limit hole can well control the distance between the color plate support structure and the factory frame beam, so that the entire color plate support structure is on an absolutely vertical plane, reducing the construction time of the color plate and increasing the aesthetic applicability of the color plate after construction.

[0034] 3. The original concrete column structure is not damaged, and the structure is safe and reliable. Compared with the traditional solution of adding post-embedded parts on the column side, adding post-embedded parts in the middle of the beam side is because the beam has less reinforcement, and most of them are arranged at the top and bottom of the beam, and there are only some waist reinforcements in the middle of the beam. The anchor bars of the post-embedded parts just stagger the stress-bearing steel bars of the beam, which greatly reduces the degree of damage to the original concrete structure and ensures the safety of the structure.

[0035] 4. Low cost, reducing construction cost. Although the addition of baffles and wind-resistant column limit plates to the assembled wall nodes of the utility model increases the amount of steel used, it reduces the time for welding, reduces labor costs, shortens the time for renting lifting equipment, greatly reduces the cost of construction, and effectively controls the construction budget.

[0036] 5. Strong versatility, which is conducive to standardized production and construction. The assembled wall sealing node of the utility model is installed on the side of the original concrete beam through post-embedded parts. The problem that the edges of the concrete beams on different floors are not in the same plane is solved by adjusting the length of the upper and lower baffles. The problem of uneven beam facades on the same floor is solved by the leveling layer, which reduces the size types of node components and greatly facilitates the mass production of components. This solution is suitable for the renovation of most concrete plants. For the situation where the cross-section of the wind-resistant column is too large or the concrete beam is originally flush with the concrete column, the node can still be used. It is only necessary to use foam plugs to fill the gaps between floors. BRIEF DESCRIPTION OF THE DRAWINGS
