Abstract

The invention discloses a sectional material. One surface of a section of the sectional material is a plane, and the other surface is a convex-concave arc wood plate with a tooth-shaped surface. Compared with the prior art, the sectional material has such advantages as beautiful appearance, sound absorption, strong fireproof performance, convenience for construction and low processing cost.

Description

A kind of section bar

Technical field

The present invention relates to a kind of materials for wall, relate in particular to a kind of section bar.

Background technology

At some buildings stadiums for example, in the construction of theater etc., the moulding of interior of building body of wall is to outward appearance, fireproof performance, the requirement of sound-absorbing etc. is very high, traditional building interior wall figure modelling is taked the form of cement paste outside fiberboard or veneer substantially, but in practice of construction process, owing to pursuing effect attractive in appearance, the inside body of wall of some buildings need to carry out special metope manufacture, such as thering is metope that several are circular-arc or circular arc is alternate etc., traditional interior of building moulding is due to the reason of the outside section bar of body of wall, be difficult to realize circular arc metope smooth construction, need to carry out significantly post-processed, so not only make construction period lengthen, productivity slowdown, cost increases, and body of wall external form is not attractive in appearance, sound-absorbing effect is poor, cause the moulded effect of body of wall bad, in the today of pursuing construction aesthetic perception, traditional section material for wall cannot meet the demand of construction.

Summary of the invention

The object of the present invention is to provide a kind of section material for wall, that this section bar has is aesthetic in appearance, sound-absorbing, fireproof performance are strong, constructability, and processing cost is low, guarantees the advantages such as body of wall whole structure.

A kind of section bar that the present invention proposes, it is that a face in cross section is plane, another face is the wooden arc-shaped plate of concavo-convex alternate toothed surface.

Described section bar is preferably made by LVL sheet material.

For making section bar more firm, the flank of tooth of described section bar is established some reinforcing ribs corresponding thereto between plane, and reinforcing rib is arranged at the bottom of the tooth of the flank of tooth centre with described plane.

The flank of tooth of described section bar is established several chaining parts on the end face between plane corresponding thereto, and chaining part is connected with section bar by bolt; The main board of described chaining part is rectangular metal plate, and main board length direction one end end top is connected with section surface, closely on main board establishes 3 countersunk head screws with section bar link position; Along a perpendicular metal sheet of end face length direction centre position welding of described main board, i.e. top board, the length of this top board is less than the length of main board, and the end top, one end of top board is pushed up concordant with the disconnected section end of main board; On described main board and be positioned at top board both sides and establish respectively one group of uniform circular hole; Described chaining part and section bar are by together with being bolted to of countersunk head screw on main board.

The present invention can realize the manufacture of the inner body of wall special shape metope of building (theater, stadiums etc.), the section bar that the present invention proposes is adding man-hour, can utilize Digit Control Machine Tool straight forming, realizes quick, Precision Machining, automaticity is high, guarantees product quality; The section bar that the present invention proposes is when practice of construction, first on concrete wall surface, by spacing (being generally 600mm), steel joist is installed, by chaining part, section bar is fixed on steel joist again, reinforcing bar dragon is connected by the bolt through through hole on main board with chaining part, a whole modeling wall surface of final formation after section bar is fixing.

The present invention compared with prior art tool has the following advantages:

Aesthetic in appearance when 1, realizing the manufacture of special shape metope, the radian of self and the flank of tooth can meet metope shape construction demand, guarantee metope overall aesthetic;

2, automation processing can reduce whole construction cost, and the cycle in operation is saved in easy construction, reduces constructor's labour intensity;

3, sound-absorbing effect is good, and the performance of setting fire is strong, and self stability is good, long service life.

the specific embodimentbelow just by reference to the accompanying drawings the present invention is elaborated.

As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5 and Fig. 6, this section bar 1 is that a face in cross section is plane 2, another face is the wooden arc-shaped plate of concavo-convex alternate toothed surface 3, this section bar is made by LVL sheet material, the flank of tooth of described section bar is established reinforcing rib 4 corresponding thereto between plane, reinforcing rib is arranged at the bottom of the tooth of the flank of tooth centre with described plane, and the flank of tooth of described section bar is established chaining part 5 on the end face between plane corresponding thereto, and chaining part is connected with section bar by bolt 6.

As shown in Fig. 7, Fig. 8 and Fig. 9, the main board 1 of chaining part is rectangular metal plate, and main board length direction one end end top is connected with section surface, closely in main body establishes 3 countersunk head screws 2 with section bar link position; Along a perpendicular metal top plate 3 of end face length direction centre position welding of described main board, the length of this top board is less than the length of main board, and the end top, one end of top board is concordant with the disconnected section end of main board top; On described main board and be positioned at top board both sides and establish respectively one group of uniform circular hole 4; Described chaining part and section bar are by together with being bolted to of countersunk head screw on main board.
