Description

Detachable floor support plate bottom die joint pin key

Technical Field

The utility model relates to a building material technique, concretely relates to can dismantle building carrier plate die block piece cotter key.

Background

The steel bar truss floor bearing plate is an important member of an assembly type building, has a plurality of remarkable advantages, is composed of steel bars, a truss and a bottom die, is improved on the basis of a profiling floor bearing plate, and is a new building material. The on-site reinforcement work load can be reduced (by about 70 percent), the construction progress is accelerated, the construction safety guarantee is increased, and the civilized construction is realized. The detachable bottom die steel bar truss floor support plate can solve the decoration problem of the top of the floor. Specifically, a plurality of steel bars are arranged on the bottom die and connected with the truss. When the floor support plate works, cement is poured on the bottom die, and after water is solidified, the floor support plate is formed after construction is finished. The detachable bottom die is characterized in that the bottom die is detachably connected with the steel bars (mainly connected through bolts), and the bottom die can be detached and separated from the steel bars after cement is fixed.

However, in the construction of a common detachable floor support plate, due to concrete construction load, truss bending deformation error and template deformation error, two adjacent bottom moulds are seriously staggered up and down at a joint, so that the bottoms of the floor slabs are uneven after the moulds are removed.

In order to solve the problem, a supporting piece is added below a joint of the bottom die or a connecting piece is added on the bottom die during a common method, the conventional connecting piece is mostly made of I-shaped steel, the connecting piece is connected with the bottom die, the adjacent connecting pieces are required to be connected, and the problem of leveling is required to be noticed during connection, so that the construction workload and the operation difficulty can be greatly increased by adding the supporting piece below the bottom die in the prior art. And on it will be when pouring cement with the connecting piece, leave behind the cement solidification with the sunken of connecting piece shape matching, can let the floor unevenness equally, the connecting piece is also convenient dismantlement simultaneously, is difficult to guarantee construction quality and reduction construction cost.

Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Example 1

As shown in figure 1, can dismantle 4 piece cotter keys of building carrier plate die block, including cotter key main part 1, cotter key main part 1 is the rectangle main part, is equipped with the vertical bar bolt hole that runs through the rectangle main part in the rectangle main part, is convenient for can dismantle with die block 4 and be connected

The one end of rectangle main part is equipped with bolt 2, and the other end of rectangle main part is equipped with bolt mouth 3, and bolt 2 matches completely with 3 shapes of bolt mouth, size, when inserting bolt 2 and inserting

bolt mouth

3, 2 faces of bolt paste tightly with bolt mouth 3 to eliminate installation error, make the building carrier plate assemble more easily.

The pins 2 are connected to the bottom dies 4 through bolts and are arranged perpendicular to the splicing seams 5, so that when two adjacent bottom dies 4 are spliced, the pins 2 of the pin keys connected with one bottom die 4 are inserted into the pin openings 3 of the pin keys connected with the other bottom die 4. Through the grafting form, realized quick concatenation, and the grafting form has guaranteed that two cotter keys align, has just so guaranteed the alignment of die block 4, and need not be like prior art after the installation connecting piece, bolted connection again after still needing to the connecting piece alignment, simple structure, and the operation is convenient fast.

Further on the die block 4 with the bolt hole that corresponds on the key main part 1 can be located the cushion below (the cushion is that floor support plate is own, mainly is in order to guarantee the clearance between reinforcing bar and the die block 4), the bolt hole that corresponds on the key main part 1 also is the cell type bolt hole that can be 1 bottoms of key main part. Of course, the bolt holes in the pin key body 1 may be ordinary bolt holes penetrating the bottom mold 4.

As shown in fig. 2, the adjacent two bottom molds 4 in the y-axis direction are spliced by the pin key body 1, while the adjacent bottom molds 4 in the x-axis direction are connected by the truss above them in the prior art, and thus, splicing is not required. And the splicing of the adjacent bottom dies 4 in the y-axis direction enables the splicing seams 5 to be aligned, so that the problem of staggered joints caused by deformation of the bottom dies 4 due to pressure during cement pouring is solved. While the pin gives support to the splice seam 5.

Example 2

As shown in fig. 4 to 5, the difference between the present embodiment and embodiment 1 is that the key body 1 is a T-shaped body, and a pin 2 is disposed at one end of the T-shaped body, and a pin opening 3 is disposed at the other end of the T-shaped body.

A T-shaped groove is arranged below the bottom die 4 matched with the seam splicing pin key for use, the notch of the T-shaped groove is positioned below the T-shaped groove, one end of the T-shaped groove is open, the other end of the T-shaped groove is closed, and the pin key is inserted into the T-shaped groove from one end of the opening and is detachably connected with the T-shaped groove. The T-shaped groove and the bottom die 4 are integrally formed.

Preferably, the end of the pin 2 of the pin key is positioned at the closed end of the T-shaped groove. The closed end of the T-shaped groove is used for limiting the pin key.

In this embodiment, adopt the cooperation of T type groove and T type main part for when the cotter key installation, need not the bolt, it is more convenient to dismantle.

As shown in fig. 4, it can be known that, because one end of the T-shaped groove is closed, the structure of the T-shaped groove is avoided due to the structural design of the T-shaped main body, and the length of the T-shaped groove is ensured to be matched with the bottom die 4.

According to the above embodiment, alright realize the utility model discloses well. It is worth to say that, on the premise of the above structural design, in order to solve the same technical problem, even if some insubstantial changes or retouching are made in the utility model, the essence of the adopted technical scheme is still the same as the utility model, so it should be in the protection scope of the utility model.
