Detailed Description
The following description will be made in conjunction with the accompanying drawings.
As a specific example, the parapet wall structure of the embodiment of the present invention includes a parapet wall body 1.
The outer side surface of the parapet wall body 1 is provided with a separation seam 11 along the height direction of the parapet wall body 1.
In a specific embodiment, the inner side surface of the parapet wall 1 is provided with a separation seam 11 along the height direction of the parapet wall 1.
The section of the separation seam 11 is rectangular or polygonal such as triangular. The corners of the polygon of the cross section of the dividing slit 11 are less stressed (compared to flat) so that the crack can be guided into the dividing slit 11.
The working principle is that when the surface stress of the parapet wall 1 generates cracks (along the width direction), the separating seam 11 can guide the cracks so that the cracks are positioned in the separating seam 11 (especially the corners of the separating seam 11, namely the polygonal corners of the section of the separating seam 11), and for inclined cracks, namely the cracks with the length which is not zero in the width direction and the height direction, the cracks can be completely limited in the separating seam 11, so that the cracks can be cut in the width direction; the adverse effect on the appearance of the parapet wall 1 is small.
The partition seam 11 on the outer side surface of the parapet wall body 1 and the partition seam 11 on the inner side surface of the parapet wall body 1 are arranged in a staggered manner, that is, there is no overlapping portion between the partition seam 11 on the outer side surface of the parapet wall body 1 and the partition seam 11 on the inner side surface of the parapet wall body 1 in a rear VIEW (i.e., a VIEW angle of VIEW 1).
As a specific example, the distance between the separation slits 11 on the same plane is equal to or greater than one meter.
The parting line 11 is filled with a flexible filler 12, and the expansion coefficient of the parapet wall 1 and the expansion coefficient of the filler 12 are different from each other. As a specific example, the filling body 12 is a non-hardening type mastic (such as a conventional asphalt mastic or a resin mastic). The expansion coefficient of parapet wall body 1, there is the difference between the expansion coefficient of obturator 12 for when obturator 12 and parting joint 11 have the difference because the deflection, the contact surface between it can stagger each other, parting joint 11 can shelter from parting joint 11, and the repair of plastering to the crack when can avoiding or reducing later stage restoration parapet wall body 1 reduces later stage restoration labour cost and material cost, reduces material waste, reduce cost to a certain extent.
The surface of the parapet wall 1 (the inner side surface, the outer side surface, the top end surface and the like of the parapet wall 1) is provided with a plastering layer (not shown in the attached drawings).
The parapet construction method of the embodiment of the invention comprises the following steps,
building a construction assembly 2, and fixedly arranging two templates 21 fixedly arranged (such as fixing through nails) or detachably arranged (such as connecting through mutual abutting) with partition bodies 22 (generally, the thickness is 15mm, the width is 30mm, and the partition bodies 22 are made of wood) at intervals;
filling concrete between the two formworks 21;
the concrete hardens to form a parapet wall 1.
As a specific example, the embedded rod 23 penetrates the form 21 and the concrete, and the mounting lug 231 is connected with the embedded rod 23 in the thread, so that the embedded rod 23 abuts against the tubular object 24 (such as a steel pipe, etc.), and the tubular object 24 abuts against the form 21 directly or indirectly (via the external abutting body 211), thereby fixing the two spacers 22. After the concrete is hardened to form the parapet wall 1, the embedded rod 23 is drawn out or the end of the embedded rod 23 is cut off.
The partition 11 is filled with a non-setting cement, and the non-setting cement is filled and set to form a filler 12.
Plastering on the surface of the parapet wall body 1 to form a plastering layer.
