Description

A new node device for cornice parapet

Technical field:

The utility model relates to a connection device for a node of a steel structure house, in particular to a novel node device for a cornice parapet of a steel structure house.

Background technique:

At present, the connection method of the parapet column of the steel structure: one is the welding connection close to the steel column, and the welding length is generally only about 300mm; the other connection method is the bolt connection close to the steel column. The current parapet column often has the following defects:

1. When the height requirement of the parapet wall is too high, the cantilever length of the parapet column is too large, resulting in a large bending moment of the parapet column, and when welding with the steel column due to the limited length of the weld, it is prone to instability, and the rigidity cannot be guaranteed ,There are security risks;

2. The width of the inner gutter is difficult to guarantee. The top of the side column of the steel structure and the connecting plate of the steel beam are mostly connected vertically. For roofs with a long single slope, the effective net width of the bottom of the inner gutter is often limited by the width of columns, connecting plates, stiffening plates, etc., and the net width of the bottom of the gutter is difficult to meet the requirement of 450mm. The size of the section is too small, resulting in the untimely drainage of the cornice and gutter, which seriously affects the drainage of the roof, and what is more serious water leakage at the gutter, causing serious economic losses;

3. The components are easily deformed during the process of production, installation and transportation, and the quality is difficult to guarantee;

4. Judging from the effect of the facade, the overall shape does not meet the aesthetic requirements of craftsmanship.

Invention content:

The purpose of this practical technology is to provide a more reasonable structure, simple production and installation procedures, low cost, can increase the effective width of the bottom of the gutter in the roof, improve roof drainage, and beautiful, atmospheric cornice parapet and steel The connecting nodes of the columns make the steel structure workshop meet the technical requirements of safety, economy, practicality, reliability and beauty.

In order to meet the above requirements, the technical solution adopted by the utility model is a new node device for cornice parapet, which is composed of H-shaped steel, thin-arm C-shaped steel, edge-sealed angle steel, corner-wrapped edge, and profiled steel plate. It is characterized in that H The section steel is welded into an inverted F-shaped parapet frame, and the two short sides are determined according to the width of the inner gutter, and the long side is determined according to the height of the parapet wall. The two short sides of the inverted F-shaped parapet frame are welded to the top of the cornice column. Thin arm C-shaped steel is used for reinforcement between each inverted F-shaped parapet frame, and profiled steel plates are used as decorative panels on the outside. The inner and outer corners are respectively sealed with angle steel and corner edging to press the decorative panel, and the corners are edged Make drainage holes every 1-2 categories, install inner gutters on the short side of the inverted F-shaped parapet wall frame, and make waterproof edges with the profiled steel panel on the parapet wall and the eaves, and install drainage pipes at the bottom of the gutter .

The advantages of the utility model technology compared with the traditional technology: 1. The inverted "F" type welded H-shaped steel skeleton structure is more stable; 2. The components are not easy to deform during the process of production, installation and transportation; 3. Solve the impact of the effective net width of the bottom of the gutter, Ensure the effective drainage of the gutter; 4. The overall shape of the eaves is beautiful, clear and atmospheric; 5. Solve the problem that the downspout in the gutter cannot be installed due to many tie rods, supports and other components; 6. Corner wrapping every other Drainage holes are set at 1-2 meters to effectively solve the problem of drainage at the corners of the overhanging eaves by using the rainwater's own weight.

7. The cantilevered length and height of the frame can be adjusted according to customer requirements. The device of the utility model is suitable for any steel structure workshop with parapet shape design requirements.

Fig. 2 is a schematic diagram of installation of a new node device for cornice parapet wall of the utility model.

detailed description:

Referring to accompanying drawing 1 and accompanying drawing 2, further description is as follows, first weld the H-shaped steel into an inverted F-shaped parapet frame 1, wherein the two short sides are determined according to the width of the inner gutter 6, and the long side is determined according to the height of the parapet, and the inverted The two ends of the two short sides of the F-shaped parapet frame 1 are welded to the top of the cornice column 2, and the thin-arm C-shaped steel 3 is used for reinforcement between each inverted F-shaped parapet frame. Use edge-sealed angle steel 5 and corner edging 7 to press the decorative panel respectively, and drill drainage holes 8 every 1-2 types on the corner edging, and install inner gutter 6 on the short side of the inverted F-shaped parapet frame , and with the profiled steel plate 4 of the finish on the parapet wall and the eaves, the waterproof edge is done, and the drainage pipe 9 is installed at the bottom of the gutter. The device of the utility model has good practicability and economy.
