Description

Technical Field

[0001] The utility model belongs to the technical field of building main body construction, and in particular relates to a floor non-disassembly formwork protective layer control component. Background Art

[0002] With the rapid development of the industrialization of construction projects, many new technologies have emerged in accordance with the requirements of national green building materials and the construction of prefabricated insulation and energy-saving systems; among them, the cast-in-place concrete steel wire mesh insulation and sound insulation non-removal formwork floor insulation system uses Class A non-combustible composite expanded polystyrene insulation board as the insulation core layer, and the polymer reinforced transition layer with built-in alkali-resistant mesh cloth is combined with the cast-in-place concrete structure and the outer leveling mortar without cavity. The cast-in-place concrete steel wire mesh insulation and sound insulation non-removal formwork is prefabricated in the factory and acts as a formwork in the cast-in-place concrete structure. It is a permanent non-removal formwork with its own insulation and sound insulation formwork functions.

[0003] This cast-in-place concrete steel wire mesh thermal insulation and sound insulation non-removal formwork also has some problems in actual construction: because the strength of its surface crack resistance layer is relatively low, the steel stirrups and pads set on the upper cast-in-place layer are very likely to be penetrated and damaged after being compressed. After the lower ends of the stirrups and pads are compressed and sink into the non-removal formwork, the upper protective layer of the steel bars is too large and the lower protective layer is insufficient; the oblique belly steel wire is stepped on and cannot maintain a certain inclination angle, affecting the overall anchoring strength of the non-removal formwork material and the cast-in-place concrete layer; at the same time, the spacing between the upper and lower steel bars on the slab surface is not easy to control, and the pre-buried wire pipes are easily squeezed during the concrete pouring process, affecting the later installation project construction. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The beneficial effects of the utility model are as follows: the integrated arrangement of the pad and the stirrup can effectively control the upper and lower steel bar protective layers, avoiding the thickness of the floor slab steel bar protective layer not meeting the standard requirements; the standardized prefabrication production method is adopted in the factory, and the equipment is directly installed after being transported to the site, which reduces the influence of human factors. At the same time, compared with the separate arrangement of the pad and the steel bar stirrup, it is not easy to deform, saves workload, and is simpler to construct. The quality of the integrated material and the steel bar protective layer can be guaranteed; the construction labor input is small, the material process is simple, the loss rate is low, the comprehensive cost is low, and the construction cost is reduced; the utility model effectively enhances the integrity of the cast-in-place steel bar layer, avoids penetration of the non-dismantling formwork anti-cracking layer, and affects the anchorage and overall strength of the non-dismantling formwork material.

[0023] The utility model is a cast-in-place formwork-free structure steel bar protective layer control component, a pad and a stirrup two-in-one material component, the bottom pad is made of C30 concrete, the average compressive strength is greater than 30Mpa after testing, the impact resistance, compression resistance and bending strength are large, the size is 40*40mm, the thickness is 30mm, the first embedded steel bar stirrup 14 and the second steel bar stirrup 15, the diameter of the "X"-shaped stirrup bar is φ4.8, that is, the steel bar support leg extends into the pad, and the total height of the steel bar protective layer control component is adjusted with the floor thickness and the protective layer thickness; when in use, the lower steel mesh is placed in the longitudinal and transverse grooves on the upper part of the pad, and the "X"-shaped stirrup bar supports the upper steel mesh; the component is light in weight, easy to transport and install, and efficient.

[0024] The floor non-removal formwork protective layer control component is mainly composed of a plain concrete pad 11 and a first steel stirrup 14,

[0025] The second steel bar stirrup 15 is composed of the longitudinal and transverse first steel bar groove 12 and the second steel bar groove 13 arranged on the top of the plain concrete pad 11, and the upper part of the first steel bar stirrup 14 is concave downward to form a U-shaped groove to fix the lower steel bars of the floor and the upper stress-bearing steel bars respectively. The bottom end of the first steel bar stirrup 14 does not contact the expansion tray 16, so that the staff can bend the first steel bar stirrup 14 to ensure that the bottom steel bars are more convenient to install.

[0026] The component is symmetrically connected with two "X"-shaped steel stirrups, which can effectively enhance the overall stability of the component. The stirrups are integrated with the lower plain concrete pad 11, avoiding quality problems such as puncture damage of the non-removal formwork and insufficient thickness of the bottom protective layer of the slab caused by construction control deviation during the construction process.

[0030] Simulating the situation in which people or heavy objects on the working floor during construction impose normal construction loads on the slab surface, the steel stirrups transfer all loads to the non-removal formwork through the integrated plain concrete stirrups. The entire steel system can remain stable under the impact of normal construction loads, and the non-removal formwork will not be damaged.
