Moldboard support beam

Abstract

A moldboard support beam including a beam body and a wooden beam installed in the beam body. The beam body has a recessed space inward recessed from the top wall of the beam body. Two hooking members are respectively formed on the two sidewalls of the recessed space and protrude from the sidewalls into the recessed space. The wooden beam is inserted in the recessed space with two sides engaged with the hooking members so that the wooden beam cannot be extracted out of the recessed space. A wooden moldboard can be nailed on the wooden beam of the support beam. By means of the hooking members, the wooden beam can be easily fixed in the recessed space of the beam body without using any other fixing member.

1 . A moldboard support beam comprising a beam body and a wooden beam installed in the beam body, wherein: 
 the beam body is integrally made of iron metal material and has a certain cross-section including:    two vertical walls which are parallel to each other and spaced by a certain distance;    a top wall transversely connected with top edges of the vertical walls;    a recessed space inward recessed from the top wall, the recessed space having two sidewalls respectively spaced from the two vertical walls by a certain distance;    two bottom walls respectively horizontally disposed at bottom ends of the vertical walls; and    two hooking members respectively formed on the two sidewalls of the recessed space, each hooking member having multiple hook sections, the hook sections being longitudinally arranged along the beam body at intervals, the hook sections protruding from the sidewalls of the recessed space into the recessed space; and    the wooden beam is downward inserted into the recessed space with two sides engaged with the hook sections of the hooking members so that the wooden beam cannot be extracted out of the recessed space.    
   
   
       2 . The moldboard support beam as claimed in  claim 1 , wherein the hook sections are reverse hooks having bottom edges protruding into the recessed space.  
   
   
       3 . The moldboard support beam as claimed in  claim 1 , wherein the bottom walls inward extend from the bottom ends of the vertical walls, the beam body further including two erect walls respectively upward extending from free ends of the bottom walls.  
   
   
       4 . The moldboard support beam as claimed in  claim 3 , wherein the erect walls are respectively vertically aligned with the sidewalls of the recessed space.  
   
   
       5 . The moldboard support beam as claimed in  claim 1 , further comprising a predetermined number of reinforcing sections disposed on the vertical walls.  
   
   
       6 . The moldboard support beam as claimed in  claim 1 , wherein each of two ends of the beam body is formed with a transverse through hole passing through the vertical walls, the bottom walls inward extending from bottom ends of the vertical walls, the moldboard support beam further comprising an axially connecting member having a rectangular tube, two vertical boards being respectively fixed on two sidewalls of each of two ends of the rectangular tube, two transverse through holes being respectively formed on two ends of the axially connecting member, the axially connecting member being fitted in the beam body with the top end and bottom end of each vertical board respectively abutting against the top wall and bottom wall of the beam body, a screwing member being screwed through the through hole of the beam body and the through hole of the axially connecting member to fix the axially connecting member with the beam body.
