Abstract

The patent of the utility model relates to a be used for cast-in-place concrete door and window entrance to a cave template to support fixture, its characterized in that: firstly, laying a template at a cast-in-place concrete door and window opening, placing battens, adjusting the space between the battens and the verticality of the template, and then installing a template supporting clamp which consists of a horizontal rod, two groups of vertical rods, a stud, a nut and a connecting bolt; the horizontal rods and the vertical rods are both made of galvanized square tubes, and the horizontal rods are uniformly provided with drill holes; the two ends of each group of vertical rods are respectively drilled, according to the cross section size of the cast-in-place concrete door and window opening, one end hole of each group of vertical rods is fixed together with a hole in the horizontal rod through a connecting bolt to form a U-shaped frame, the other end hole of each group of vertical rods is aligned with a hole reserved in the template, the stud is inserted into the hole and screwed down by a nut, and the phenomena of expansion, irregular external corner and the like at the cast-in-place concrete door and window opening can be avoided.

Description

Be used for cast-in-place concrete door and window entrance to a cave template to support fixture

Technical Field

The patent of the utility model relates to a be used for cast-in-place concrete door and window entrance to a cave template to support fixture mainly applies to the construction field.

Background

In a cast-in-place concrete structure, a part of door and window openings are formed in one step by cast-in-place concrete, because the cross section of the part is small, the external corners are more, the reinforcing mode is complicated, and steel pipe fasteners are adopted for reinforcing in the past, so that the reinforcing method causes the phenomena of expansion and irregular external corners during concrete pouring, and influences the clearance size of the door and window openings and the impression quality of the concrete pouring.

Disclosure of Invention

The utility model aims at avoiding the cast-in-place concrete door and window entrance to appear expanding die and the phenomenon such as external corner is square and invent a finished product is of high quality, easy operation's template supports fixture.

The utility model aims at adopting following mode to realize:

firstly, laying a template at a cast-in-place concrete door and window opening, placing battens, adjusting the space between the battens and the verticality of the template, and then installing a template supporting clamp which consists of a horizontal rod, two groups of vertical rods, a stud, a nut and a connecting bolt; the horizontal rods and the vertical rods are both made of galvanized square tubes, and as the sizes of the cross sections of the openings of the cast-in-place concrete doors and windows are different, drilling holes are uniformly distributed on the horizontal rods and are used for adjusting the fixed size of the cross section of the opening of the cast-in-place concrete door and window; the two ends of each group of vertical rods are respectively drilled, according to the cross section size of the cast-in-place concrete door and window opening, one end hole of each group of vertical rods is fixed together with a hole in the horizontal rod through a connecting bolt to form a U-shaped frame, the other end hole of each group of vertical rods is aligned with a hole reserved in the template, the stud is inserted into the hole and screwed down by a nut, and the phenomena of expansion, irregular external corner and the like at the cast-in-place concrete door and window opening can be avoided.

The utility model has the advantages that: by adopting the template supporting fixture, the phenomena of expansion of a cast-in-place concrete door and window opening, irregular external corner and the like can be avoided, the size of the door and window opening is ensured, the impression quality after concrete pouring is improved, the construction efficiency is effectively improved, the template supporting fixture can be repeatedly used for many times, and the cost is reduced.

Drawings

Fig. 1 is a usage state diagram of the present invention.

Fig. 2 is a left side view of fig. 1.

Referring to fig. 1 and 2, the utility model discloses a including cast in situ concrete door and window entrance to a cave 1, template 2, flitch 3, pole setting 4, nut 5, stud 6, horizon bar 7, connecting bolt 8.

Detailed Description

Firstly, laying a template 2 at a cast-in-place concrete door and window opening 1, placing battens 3, adjusting the space between the battens 3 and the verticality of the template 2, and then installing a template supporting clamp which consists of a horizontal rod 7, two groups of vertical rods 4, a stud 8, a nut 5 and a connecting bolt 8; the horizontal rods 7 and the vertical rods 4 are both made of galvanized square tubes, and as the sizes of the sections of the cast-in-place concrete door and window openings 1 are different, drilling holes need to be uniformly distributed on the horizontal rods 7 for adjusting the fixed size of the section of the cast-in-place concrete door and window opening 1; the two ends of each group of vertical rods 4 are respectively drilled, according to the section size of the opening 1 of the cast-in-place concrete door and window, one end hole of each group of vertical rods 4 is fixed together with a hole on the horizontal rod 7 through a connecting bolt 8 to form a U-shaped frame, the other end hole is aligned with a hole reserved on the template 2, the stud 6 penetrates into the hole and is screwed up by the nut 5, and the phenomena of expansion, irregular external corner and the like of the opening 1 of the cast-in-place concrete door and window can be realized.

Claims

1. The utility model provides a be used for cast-in-place concrete door and window entrance to a cave template to support fixture which characterized in that: the template supporting clamp consists of a horizontal rod, two groups of vertical rods, a stud, a nut and a connecting bolt; the horizontal rods and the vertical rods are both made of galvanized square tubes; drilling holes are uniformly distributed on the horizontal rod; the two ends of each group of vertical rods are respectively drilled, a hole at one end is fixed with a hole on the horizontal rod through a connecting bolt to form a U-shaped frame, a hole at the other end is aligned with a reserved hole on the template, a stud is inserted into the hole and is screwed up by a nut.
